The maintenance and enhancement of our quality of life, our economic wealth, and the health of our citizens are dependent on our natural environment and the ecological services it provides. As defined by Gretchen Daily in her book, NatUre's Services, "ecological services" are "the conditions and processes through which natural ecosystems, and the species that make them up, .sustain and fulfill human life." The ecological functions provided by the County's environmental resources that are critical to our economy and quality of life include: * purification of air and water * mitigation of floods and droughts * detoxification and decomposition of wastes * generation and renewal of soil fertility * pollination of crops , control of pests * maintenance of bidiversity for human needs . moderation of climate, including temperature extremes, wind, etc. * aesthetic beauty and intellectual stimulation * recreation This Natural Resources and Cultural Assets Chapter applies to both the Development Areas and the Rural Area. It discusses the concept of sustainability; the physical setting of Albemarle County; open space resources, including natural, scenic and historic resources; ~d open space planning. Water resources, (including surface water, surface drinking water and groundwater), and agricultural and forestry resources are discussed under natural resources. This chapter incorporates as a freestanding document the Open Space and Critical Resources Plan, originally adopted in 1992 as part of the Comprehensive Plan. [It is anticipated that it will also incorporate the Historic Preservation Plan, being prepared by the Historic Preservation Committee.] Included in Appendices are the Mountain Protection Plan, prepared by the Mountain protection Committee in 1996, and the detailed Greenways Plan. Sustainability GOAL: Achieve a sustainable community which meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainability is a concept which recognizes that natural systems are essential to providing both economic needs and quality of life. The goal of sustainable development is to accomodate economic development, while protecting the environment for present and future needs. Sustainability gained international attention at the 1992 United Nations' Conference on Environment and Development. In 1993, the Virginia General Assembly passed House Joint Resolution No. 653, encouraging the Governor, state and local officials, and the leaders of educational institutions and civic organizations to work together to prepare a Virginia strategy for sustainable development. The Thomas Jefferson Sustainability Council was created in 1994 by the regional Thomas Jefferson Planning District Commission. The Council grew out of the 1990-92 Thomas Jefferson Study to Preserve and Assess the Regional Environment (TJSPARE). It is a 34-member council with representatives from the six member localities: Albemarle, Fluvanna, Greene, Louisa and Nelson Counties, and the City of Charlottesville. The diverse group of farmers, business people, foresters, environmentalists, developers and elected officials was given the charge to, "describe a future where our economic, human, social, and environmental health are assured." The Council addressed the areas of: human population, basic human needs, economic development, transportation, land development, waste, values/ethics, community awareness, interdependence/balance, government, natural environment, and agriculture/forestry. Th.e Council has developed a mission statement, principles which govern a sustainable community, and the goals, objectives, indicators and benchmarks of a sustainable region. These conclusions stress the importance of taking the long view and the interdependence of all aspects of a community. The Mission of the Thomas Jefferson Sustainability Council is to provide citizens throughout the Region with information and encouragement to meet the needs of the present without compromising the ability of future generations to meet their own needs. ~ The final product of the Council's work is development of 15 Statements of Accord. The Council now seeks to develop a consensus through the Accords and the State of the Region Report in the localities, within local governments and among the diverse interests of the community to work together for a sustainable future in the Region. Strategy: Review and support as appropriate the following Sustainability Council's Statements of Accord: Encourage and maintain strong ties between the Region's urban and rural areas, fostering healthy economic, environmental, social and political interactions. Strive for a size and distribution of human population which will preserve the vital resources of the Region for future generations. Retain the natural habitat required to support viable plant and animal communities which make up the Region's biological diversity. Ensure that water quality and quantity in the Region are sufficient to support the human population and ecosystems. Optimize the use and reuse of developed land Promote clustering in residential areas and the 2 integration of business, industry, recreation, residential and open space. Promote the consideration of appropriate scale in all development and land use decisions. Retain farmland and forest land for the futur~ Broaden the use of sustainable forestry practices among loggers and landowners. Promote the sale of locally produced farm and forest products in local, national and international markets. Develop attractive and economical transportation alternatives to singe occupancy vehicle use. Promote the conservation and efficient use of energy resources. Provide, at all levels, educational opportunities open to every member of the community. Ensure that every member of the community is able to obtain employment that provides just compensation, mobility, and fulfillmena Increase individual participation in neighborhood and community organizations. Encourage greater understanding of sustainability issues as they affect individuals and the Region, using formal and informal education and local media coverage. Physical Setting Location and Geography The County of Albemarle lies in the central part of the Commonwealth of Virginia. Charlottesville, which is located basically in the center of the County, is approximately 70 miles from Richmond, 115 miles from Washington, D.C., 189 miles from Virginia Beach, 21 miles from Skyline Drive, 68 miles from Lynchburg, and 123 miles from Roanoke. Albemarle is bordered on the north by Greene and Orange Counties, on the east by Louisa and Fluvanna Counties, on the south by Buckingham County, and on the west by Nelson, Augusta, and Rockingham Counties. The crest of the Blue Ridge Mountains forms the northwestern edge of the County. The County is included in the Charlottesville Metropolitan Statistical Area (MSA), which was designated by the U. S. Department of Commerce in 1981. The MSA is made up of Charlottesville and Albemarle, Greene and Fluvanna Counties. Area Albemarle, the fifth largest county in the state, contains 465,040 acres or 726.6 square miles of land area, of which six square miles are water. Within this area is the Town of Scottsville which contains about 833 acres or 1.3 square miles, and the Shenandoah National Park, which contains 15,000 acres, or 23.4 square miles. Not included in the County area figure is the City of Charlottesville, a separate jurisdiction which contains approximately ten square miles. Albemarle County is shown in Map--. Geology Albemarle County is underlain by bedrock which, in its western half, is primarily igneous and metamorphic in character..The eastern part of the County is underlain by sedimentary and igneous rocks which have been subjected to different degrees of metamorphism. Sedimentary rocks of Triassic age occur in the vicinity of Scottsville and Burnleys. Throughout the County th~ rocks outcrop in broad belts extending in a northeasterly- southwesterly direction. The major structural feature is the Southwest Mountains - Blue Ridge anticline. This is a great recumbent anticline with drag folds bounded on the east by the Southwest Mountains and on the west by the Blue Ridge Mountains. It is bisected by the Mechums River graben, a down-faulted belt of metamorphosed rocks, composed of the Rockfish conglomerate, the Lynchburg gneiss, the Charlottesville formation and the Mechums River formation. For further information on the geology and mineral resources of Albemarle County, consult the Geology and Mineral Resources of Albemarle County, published by the Virginia Division of Mineral Re. sources, 1962. (See also Groundwater Resources, page --, and Mineral Resources, page -.) Topography Albemarle County is situated within two physiographic provinces: The Blue Ridge Physiographic Province and the Piedmont Physiographic Province. The highest point in the County, 3,389 feet (1,033 m), is on the crest of Big Flat Mountain in the extreme northwestern corner of the County. The lowest elevation, approximately 235 feet (72 m), occurs where the Rivanna River crosses into Fluvanna County just south of Boyd Tavern. The elevation of Charlottesville is approximately 500 feet (152 m). Most areas of the County 4 lie below 1,000 feet (305 m) in elevation. Approximately 83,634 acres are designated as Mountains, including 15,000 acres in the Shenandoah National Park (See Map -). Slope Slope refers to the slant or steepness of the land. suitability and physical development. It is one of the most important determinants of land use Slope is expressed in a percentage as measured by the number of feet change in elevation per 100 horizontal feet. The following list provides a description of various slope categories: 0-2% flat land; 3-7 % rolling, moderately sloping; 8-15 % hillside; '16-24% steep hillside; 25% + critical slope. The County's steepest lands are concentrated on its western border and are made up of the eastern slopes of the Blue Ridge. Other major concentrations of steep terrain include a series of mountains in the southwest quadrant of the County and the north south linear formation made up by the Southwest Mountains and Carter's Mountain (see Map -). Critical slopes are discussed further under the Natural Resources section, page --. Climate Warm, humid summers, and mild winters characterize the climate of Albemarle County. The mountains along the western boundary, along with the Chesapeake Bay and the Atlantic Ocean to the east, are major factors controlling the climate, in addition to the latitude and location on the North American continent. Records from the State Climatologist's Office (1961-90) in CharlOttesville indicate that the average annual temperature in the area is approximately 57°F (13.9°C). Extremes have been recorded as high as 107°F (41.7°C) in September, 1954, and as low as -10°F(-23.3°C) in January, 1994. The average annual precipitation is approximately forty-seven (47) inches, and rainfall is the dominant form of precipitation. The average annual snowfall is approximately twenty-four (24) inches. The typical growing season (from the last freeze In spring to the first freeze in autumn) is 210 days. Freezes usually do not occur between April 7 and November 4. However, freezing temperatures have occurred as late as May 10 and as early as October 3. OPEN SPACE RESOURCES GOAL: Protect the County's natural, scenic, and historic resources in the Rural Area and Development Areas. Introduction Open space resources include natural, scenic, and historic resources. Natural resources discussed in this chapter include, among others, water resources, agricultural and forestry resources, biological resources, and mountains. Natural, scenic and historic resources are recognized in both the Rural Area and the Development Areas of the County, but these open space resources, and resource protection efforts, are more closely tied to the Rural Area through the Growth Management goal. There is a strong relationship between natural, scenic and historic resources, water supply protection, and agricultural and forestry preservation, which are defining elements for the Rural Area.- Agricultural and forestry resources are recognized and protected for agricultural and forestry uses uniquely in the Rural Area. Those uses are discussed further in Chapter Four, the Rural Area. Natural, scenic, and historic resources are essential to Albemarle County's character, both rural and urban, its economic vitality, and quality of life.. The three types of open space resources are discussed separately in the following sections. Often, however, a single reSOurce will serve all three functions. The Rivanna River, for example, is a natural resource which provides aquatic habitat and floodplain; it is a scenic resource which is designated a Virginia Scenic River; and it is a hiStoric resource with evidence of canal locks remaining from the days when it was a major transportatiOn route. All open space resources have several properties in common: · Open space resources provide multiple benefits: ecological, educational, recreational, aesthetic, and ecoriomic. · They share interdependency. Protection or misuse of one resource will also protect or adversely affect other resources. For example, the maintenance of forested areas protects surface and ground water quality, wildlife habitat, critical slopes, and air quality. Open space resources are non-renewable. They can be depleted, such as through the conversion of farmland, or the destruction of a historic resource; or they can be degraded, such as through the polluti°n of drinking water supplies. These characteristics increase the importance of providing open space resource protection. The ways that we currently use and protect our open space recources will determine whether we will be able to maintain our current quality of life into the future. The concept of sustainability provides a method to objectively look at our actions, and to ensure the stewardship of Albemarle County's resources for future generations. The Open Space and CriticalResources Plan, adopted in 1992, consolidates information on open space resources in a comprehensive and integrated fashion in order to identify the most important areas to protect as open space. It identifies four major systems of open space which extend across the boundaries of the Rural Area and the Development Areas: Major Stream Valleys, Important Farmlands and Forests, Mountains, and Cultural Resources. This Comprehensive Plan continues that effort to identify resources and to recommend appropriate protection measures. 6 · Natural Resources GOAL: Preserve and manage the County's natUral resources in order to protect the environment and to conserve resources for future use. Natural resources in Albemarle include its surface water and groundwater resources, biological resources, agricultural and forestry resources, critical slopes, mountains, the dark sky, wooded areas, soils, air, and minerals. Conservation of natural resources, avoids wasteful or destructive uses, and provides for future availability. Unwise use of these resources constitutes a potential danger to the public health, safety, and welfare. It is the County's intent that development and other human activity should adapt to the natural environment, rather than unnecessarily modifying the natural environment with unknown consequences to accommodate development and man's activities: Regulations which currently protect natural resources are referenced under each section. Standards, where 'applicable, are statements of desirable levels of protection for resources. They are intended to assist in evaluation of rezoning, special use permit, site plan, subdivision, and other reviews, and are presented in the form of recommendations. 7 Water Resources GOAL: Protect and conserve the County's surface water and groundwater supplies for the benefit of Albemarle County, the City of Charlottesville, the Town of $cottsville, downstream interests, and ecological communities in the region. Introduction Protection of water resources is of vital importance io Albemarle County and Virginia in general. Albemarle's location adjacent to the Blue Ridge Mountains provides both the advantage of clean headwaters, and a responsibility to protect them. Albemarle shares the statewide concern for the water quality of the Chesapeake Bay. The County's water resources program includes watershed protection for drinking water supplies, groundwater protection, Chesapeake Bay protection, storm water management, and implementing best management practices. The program, however, cannot function without effective education and outreach and the active participation of concerned citizens. Citizens have been and will continue to be active in stream monitoring, stream clean-ups, and spreading the message of environmental stewardship. Although Albemarle County has been undertaking water resources protection for many years, this effort is represented by an assemblage of various programs, as outlined above. As our population continues to grow and stresses on our water resources increase, it is becoming imperative that the various components of the water resources programs be unified in philosophy and action to represent a cohesive and effective vision of how to protect these vital resources into the future. In other words, it is important that the whole become more than the sum of the parts. PRINCIPLES In order to strive for this unification, we Understand the following principles about the natural landscape and the people that inhabit that landscape: Water resources do not follow jurisdictional boundaries. Albemarle County is connected hydrologically (through surface water and groundwater) to the City of Charlottesville, Greene County, Fluvanna County, Nelson County, Louisa County, Orange County, and the rest of the Chesapeake Bay watershed. Surface water and groundwater are interconnected Systems. The quality and quantity of one is interdependent on the quality' and quantity of the other. For instance, groundwater recharges springs and streams, Impervious surfaces reduce groundwater recharge and increase the rate and volume of surface water discharge during storms. Our populatiOn is dependent for its health and well-being on both surface water and groundwater. Our businesses, industry and jobs, not just residents, are also dependent on water resources. Approximately half of the County's population uses surface water for consumptive uses through the public system consisting of five reservoirs and one run-of-the-river intake. The other half uses groundwater via private, individual wells and springs or small community systems. As our population grows and stresses on water resources increase, we must increasingly strive to use these resources in an efficient manner. The more use we get out of every gallon of water leaves more in streams and groundwater for the maintenance and health ofnatural ecosystems. Economically, this approach will help keep our current resources viable into the future. 8 Land use and development should strive to work with natural processes to minimize, by design, impacts on streams and groundwater. This includes reducing impervious cover and incorporating design features that consider runoff quantity and quality, the integrity of natural stream channels, and aquatic habitats. All land uses, landowners, and residents (urban, suburban, agriculture, forestry) share the responsibility for preserving, protecting, and enhancing water resources in the community for current and future generations and the biological communities we share this landscape with. The Comprehensive Plan, while enumerating the specific programs that compose water resources management, must always refer back to these guiding principles to establish a blueprint for philosophy and action. PUBliC EDUCATION OBJECTIVE: Implement an ongoing educational program for the general public that emphasizes protection of surface and groundwaters and the property owner's responsibility. Coordinate efforts with the public schools, the EnvirOnmental Education Center, Thomas Jefferson Soil and Water Conservation District, the Rivanna Water and Sewer Authority, Albemarle County Service Authority, Ivy Creek Foundation, Thomas Jefferson Sustainability Council, and other local environmental education efforts. Individual households and farms play an important role in the prevention of surface water and groundwater pollution. Non-point source pollution of surface water will result from runoff carrying sediment, agricultural and lawn chemicals and nutrients from fertilizers, septic system effluent, and toxic substances such as oil and antifreeze. Groundwater can also be threatened by seepage of agricultural and household products and waste and underground storage tanks for home fuel oil and other products. AgricUltural uses are exempt from many water protection regulations. Therefore, voluntary techniques must be conveyed to farmers that will both educate and inspire positive measures on their part. For the typical County household, environmental stewardship is voluntary. It is important that property owners understand the impact of their daily activities and how to help protect water resources. Public education to residents (not only property owners) should be included in water bills, tax bills, or other means of disseminating water protection information.' Also, activities should be coordinated with other local environmental education efforts. EXISTING COUNTY REGULATIONS OBJECTIVE: Continue to enforce all existing regulations for the protection of water resources. The County's preexisting water resources ordinances were consolidated and updated in the form of the Water Protection Ordinance (Chapter 19.3 of the Code of Albemarle), which was adopted by the Board of Supervisors on February 11, 1998. This ordinance replaced the following ordinances: (1) Erosion and Sediment Control Ordinance, (2) Runoff Control Ordinance, (3) Water Resources Protection Areas Ordinance, and (4) the stormwater detention requirements of the Subdivision Ordinance. The intention of the new ordinance is to simplify the administration of water-related development review, eliminate redundancy between programs, provide a more user-friendly process for applicants, and create a more comprehensive and up-to-date water resources program. 9 In addition to the Water Protection Ordinance, the other programs listed below are County efforts that directly or indirectly benefit water resources: Rural Areas zoning; Critical slopes regulations; Flood hazard overlay regulations; Supplementary regulations for tree cutting; Scenic overlay for designated streams; Industrial performance standards and restrictions on excessive water use or discharges other than domestic waste; and, Site plan requirements including soils suitability and storage of potential pollutants. Strategy: Produce a local Design Manual with criteria for complying with all regulations. The Engineering Department should lead the effort of Design Manual production. 10 AGENCIES RESPONSIBLE FOR WA'rER RESOURCES IN VIRGINIA Virginia has an intricate web of agencies responsible for different aspects of water resources management.

WATER RESOURCES COMMITTEE OBJECTIVE: Maintain a water resources committee to coordinate local water resources protection matters. The Water Resources Committee began meeting in 1989. Current membership includes representatives from County Planning and Engineering Departments, the Rivanna Water and Sewer Authority, the Thomas Jefferson Soil and Water Conservation District, and the Soil Conservation Service. Non-appointed representatives include members of the Planning Commission, the development community, and an environmental organization. The Committee has addressed the following topics: streamlining and consolidation of County water resources ordinances, stormwater management, review of the South Fork Rivanna Reservoir Watershed Management Plan, permitting and construction of the Liekinghole Creek regional sedimentation basin, development of the Water Resources Protection Areas Ordinance, review of the Groundwater Protection Study and pilot groundwater project, and review of the Water Resources section of the Comprehensive Plan. Committee membership should include citizens involved in fanning and forestry. It should also be broadened to include City, University, neighborhood, and civic organization representation. This is particularly relevant in light of the Moores Creek study for stormwater management, a joint effort between the County, City, and University. Such a committee would be able to consider water resources issues in a collaborative and regional fashion, and would facilitate communication between jurisdictions on water resources topics. Strategy: The Committee should continue to work towards coordination and citizen participation at the committee level Strategy: Broaden membership on the committee to include citizens involved in farming and forestry, representatives from the City of Charlottesville, the University of Virginia, Thomas Jefferson Health District, other relevant agencies, and community organizations. Strategy: Seek input through coordination with existing committees such as the Planning and Coordination Council's technical committee, P~I CC- Tech. Strategy: The Committee should work through ad hoc committees to address timely and relevant water resources topics, either at their own discretion or at the discretion of the Board of Supervisors or Planning Commissiota 16 Surface Water OBJECTIVE: Protect the County's surface water through a management program that recognizes the functional interrelationship of stormwater hydrology, stream buffers, floodplains, wetlands, and human management practices. It is a challenge to balance public (human) uses for surface water with the maintenance of water-dependent ecosystems. In this regard, the following sections outline the components of surface water management in Albemarle County. The initial section outlines the geography of Albemarle's watersheds. Subsequent sections discuss aspects of surface water management: public uses, stormwater management, Chesapeake Bay and stream buffers, flood plain management, wetlands, voluntary best management practices, and the consideration of special resource areas. It is important to understand that these program areas are interrelated. For instance, stormwater management influences flooding and flood plains; stream buffers and wetlands protect stream channels from stormwater and help absorb flood waters; and best management practices prevent pollution of local streams and the Chesapeake Bay. While each program area is given separate treatment in this chapter, their functional interrelationship remains the most important feature of sound water resources management. MA]OR WATERSHEDS Albemarle County forms the headwaters for the Middle James River Basin, with only a small portion of northeast Albemarle draining into the York and the Rappahannock River basins (see Map --). The entire County is part of the Chesapeake Bay Basin. Each major river basin (James, York, Rappahannock) contains several smaller river watersheds (e.g., The North Fork'Rivanna, South Fork Rivanna, and Hardware River watersheds are components of the James River Basin). Similarly, within each river watershed are yet smaller stream and creek watersheds (e.g., the Moormans and Mechums river drainages are components of the South Fork Rivanna Watershed). These smaller watershed units can be viewed as "home" watersheds, as they are at a geographical scale that people can actually experience, much like a neighborhood or the jurisdictional limits of a town. For Albemarle County, the following list outlines each major river basin along with the river and home watersheds that form their building blocks: 17 Middle James River Basin North Fork Rivanna River 1.

Graphics and In[ormaLion Resources PUBLIC USES AND ECOLOGICAL VALUES OBJECTIVE: Maintain the integrity of existing stream channels and networks for their biological functions and drainag~ Protect the condition of state waters for ali reasonable public uses and ecological functions. Restore degraded stream and wetland ecosystems where possible. Surface water serves many purposes: drinking water supplies, recreation (swimming, fishing, boating), agriculture (irrigation, livestock), industrial and commercial uses, wastewater assimilation, scenic beauty and open space, aquatic and shoreline habitat, and drainage. Withdrawals for public drinking water supplies are a major use of surface water in Albemarle. The current demand for public drinking water exceeds 12 MGD (see Surface Drinking Water, p-- and the Land Use Plan Chapter, Public Water and Sewer section, p. 109). There is minor demand for golf courses and quarries. Agricultural uses of surface water include watering of livestock and irrigation, although exact rates are difficult to determine. Fi shing and boating are permitted on all County reservoirs. Lake Albemarle near White Hall is designated a public fishing lake. Several streams in northwest Albemarle are designated natural trout waters by the DEQ: North and South Fork Moorman's River, Doyle River, Jones Run, and Pond Ridge Branch. County swimming facilitieS are provided at Mint Springs Lake, Chris Greene Lake, and at Walnut Creek Regional Park. As land use changes occur one parcel at a time, it can be difficult to ascertain cumulative impacts to water resources. A "tragedy of the commons" can ensue if each parcel-level impact is deemed acceptable according to existing standards while the larger ecosystem declines incrementally to levels that the community would otherwise find unacceptable. One approach used by federal and state agencies to address this phenomenon is "Total Maximum Daily Load," or TMDL. The use of TMDL's for a given river segment allows regulatory agencies to determine acceptable pollutant loads for that river as a whole, and then to allocate pollutant limits to the various pollution sources within the river basin such that the total acceptable load is not exceeded. Of course, how and by whom the "acceptable" pollutant level is set is of critical importance to this approach. There may be a better method to assess the cumulative effects of land use decisions. TMDL's set pollution thresholds but may not discourage pollution. TechnolOgies and approaches to restore degraded ecosystems are continually being developed and refined. While promising, restoration is an extremely complex undertaking, as a web of interconnected factors (e.g., hydrology, vegetation, geology, soils) must be understood to create a successful design. In addition, costs can be high and outcomes uncertain. For these reasons, it is essential to: (1) place major emphasis on protecting water resources before they become degraded or furflaerdegraded (from existing conditions), and (2) establish priorities for restoration to make best use of technical and financial resources. Strategy: The County should adopt a TMD£ or similar approach to understand cumulative impacts and to prevent ecosytem degradation. Strategy: Create a prioritization method for restoration projects to make best use of resources. 20 5'I'ORMWATER MANAGEMENT OBJECTIVE: Protect the safety and welfare of the citizens, 'property owners, and businesses by minimizing the negative impacts of increased stormwater discharges from new land developmena OBJECTIVE: Facilitate the integration of stormwater management and pollution control with other programs, policies, educational efforts, and Comprehensive Plans of jurisdictions in the region. Urban and suburban development changes the nature of streams and drainage ways, and can result in increased flooding, loss of groundwater recharge, and water quality degradation. Pollutants present in urban and suburban runoff include: sediment, fertilizers, pesticides, heavy metals, bacteriological contaminants, and grease and oil, among ether pollutants. Since 1980, the County has required development in an urban and urbanizing Portion of the County known as the "storm water detention area" to utilize facilities that detain storm water. The purpose of these measures is to protect downstream properties from excessive drainage, erosion, and flooding. As part of the process of developing the Water Protection Ordinance, the County has been studying how the storm water program can be enhanced to be more comprehensive, to Coordinate storm water management within entire drainage basins, to incorporate water quality concerns, and to improve the design and maintenance of storm water facilities. The Design Manual currently under development will further refine County guidance on these matters. The standards developed in the Water Protection Ordinance should also be considered by the City and University. The regionalization of stormwater management has been discussed by PACC-Tech and other City/County/University forums, and a focus group with regional representation assisted with the development of objectives for the new ordinance. It certainly makes sense to address drainage and stormwater in a regional framework, especially for Moores Creek, Meadow Creek, the Rivanna River, and the drinking water supplies, since all of these resources are shared by the region's jurisdictions. Watershed studies for Moores Creek and the South Fork Rivanna (including Meadow Creek) watersheds were completed in 1997 by Dewberry & Davis. The County, City, and University all contributed funds to the development of these studies. The studies include hydrology, hydraulics, water quality, and stormwater recommendations for those drainage basins. An associated EPA grant included the following activities: teacher workshops for City and County teachers on watershed education, the development of a watershed team concept, storm drain stenciling, and the training of citizen stream monitoring teams. The Moore's Creek and South Fork Rivanna watershed studies recommend the following actions: · Develop stormwater management practices and policies. · Develop proactive flood hazard mitigation practices. · Develop a prioritized remedial plan for watershed improvements. · Develop a monitoring program. · Implement a public awareness and education program. The major projects outlined above will change the nature and scope of how the County manages stormwater runoff. Strategy: Control nonpoint source pollution, erosion and sedimentation, and stream channel erosion. Strategy: Implement the recommendations of the Moores Creek and South Fork Watershed Studies. Initiate additional watersheds studies based on a prioritization plan. Strategy: Encourage the design and construction of creative and effective stormwater facilitie~ and best 21 management practices, including nonstructural approaches. Provide for the long term maintenance of these practices and facilities. Strategy: Future Development Area boundaries should follow watershed divides in order to coordinate land use policy and water resources policy. Strategy: Coordinate within the County government, with State'agencies, and with the design and development communities to encourage development and transportation design that reduces impervious cover, and that minimizes, by design, adverse impacts on Water resources. CHESAPEAKE BAY AND LOCAL STREAM CORRIDORS OBJECTIVE: Continue to support Chesapeake Bay protection initiatives. OBJECTIVE: Preserve designated Stream Valleys in their natural state in order to protect significant resources associated with stream valleys and to provide buffer areas. The Chesapeake Bay Program is a partnership between the U.S. Environmental Protection Agency and the signatories to the Chesapeake Bay Agreement: the states of Virginia, Maryland, and Pennsylvania, and the District of Columbia. Each jurisdiction has adopted its own programs and regulations in a regional effort to restore the Chesapeake Bay ecosystem. Indicators for. which data continue to be collected include: hutrient levels, concentrations of toxic chemicals, the health of submerged aquatic vegetation, fish populations, and habitat integrity. The General Assembly adopted the Chesapeake Bay Preservation Act in 1988, which establishes the Chesapeake Bay Local Assistance Board to promulgate regulatiOns and criteria for land use controls to protect the Bay. Local governments in the Tidewater area are required to: (1) incorporate general water quality protection measures into their comprehensive plans, zoning ordinances, and subdivision ordinances; and, (2) establish programs in accordance with the Board's criteria that define and protect Chesapeake Bay Preservation Areas. The Commonwealth is required to provide assistance to 16cai governing bodies, and all agencies of the Commonwealth must exercise their delegated authority in a manner consistent with water quality protection provisions of local plans and ordinances. In June of 1991, Albemarle County became the first, and remains the only, non-Tidewater locality in Virginia to voluntarily adopt a local Chesapeake Bay protection ordinance:~ This action broadened the County's approach to water resources issues to a County-wide and regional perspective. This includes a recognition that Albemarle County is one piece of the Chesapeake Bay watershed, and that local efforts to help restore the Bay will also benefit the health of stream and rivers within the County. Albemarle County's Water Protection Ordinance is a local effort to enhance the quality and health of local streams and rivers and help in the Bay restoration effort. The ordinance establishes stream buffers along many County streams and associated non-tidal wetlands.'The intent of the ordinance is to maintain areas of vegetation along perennial streams (and intermittent streams within a drinking water watershed) and associated wetlands in order to retard runoff, prevent erosion, filter pollutants from runoff. The buffer areas also function to moderate stream ~ A few other localities, such as Clarke and Loudoun counties, have adopted stream buffer type ordinances through their zoning ordinances, but not under the auspecies of the Chesapeake Bay Preservation Act. 22 qALBEMARLE /f~, COUNTY, VIRGINIA~'~ '~ CHESAPEAKE BAY WATERSHED Department of Planning and Community Development *Office of Ya, pping. Graphics and Information Resources (OOMGAIR} j 23 temperature and provide high quality habitat for aquatic and terrestrial life, including fish, and other types of wildlife. Mitigation Plans are required for development activities that propose to encroach into the buffer areas, and mitigation measures are required. For agricultural activities, buffer encroachments are allowed as long as soil and water conservation practices are employed. The Thomas Jefferson Soil and Water Conservation District (TJSWCD) administers the ordinance for agriculture. TJSWCD also employs the Virginia Best Management Practice Cost-Share Program to provide financial assistance for agricultural landowners to implement runoff control and nutrient management practices. The program uses a prioritized list of watersheds to target its BMP funds; in Albemarle County, the Totier Creek watershed has the highest priority. A lesson from implementation of the stream buffer program to date is that it is better to leave existing buffer areas undisturbed than to attempt to recreate buffers through revegetation, which can be costly and have uncertain success. Therefore, the program's chief challenge is to build awareness and acceptance of the ordinance among those regulated by it and the general public so that land disturbing activities are designed around the buffer areas instead of trying to mitigate encroachments after they occur. Efforts to protect and enhance stream buffers mesh closely with areas designated in the Open Space Plan as "Major and Locally Important Stream Valleys.' These areas include 100 year floodplains, adjacent non-tidal wetlands, critical slopes, and soils with severe restrictions due to flooding or wetness. The Open Space Plan recommends that these stream valleys be protected for environmental purposes and as important community open space corridors. Strategy: Develop guidelines (or standards) for activities in stream buffer areas to be incorporated into the County Design Manual FLOODPLA~'NS OBJECTIVE: Protect floodplains from inappropriate uses and recognize their value for stormwater management and ecological functions. Flooding occurs regularly on all major streams. Major flooding occurred, especially near Scottsville, in 1969 during Hurricane Camille and in 1972 during Hurricane Agnes. As a result, a federal grant was obtained in order to construct an earthen dike to protect the Town of Scottsville. The Route 29 North Urban Area experienced flash flooding in 1982 as a result of an unusually severe localized storm. The Moorman's River experienced major flooding and debris flows during June, 1995 storms. In December, 1980, new flood hazard maps and the Flood Hazard Overlay District were adopted as part of the County's Zoning Ordinance. This action was the basis for the Federal Emergency Management Agency to increase Albemarle County's coverage under the National Flood Insurance Program. In order to continue under this program, the County must strictly adhere to zoning regulations governing floodplain usage. Flood hazard areas are those lands identified as being subject to flooding by a one-hundred-year storm. The U.S. Army Corps of Engineers maps delineate floodplains for ali streams having a watershed of one square mile or greater. In addition, the Site Development Plan section of the Zoning Ordinance requires delineation of one- hundred-year floodplain limits for all watercourses with watersheds of fifty acres or more. Soils which are limited by occasional or frequent flooding are also addressed in the Zoning Ordinance. Encroachment into floodplain lands by development and inappropriate uses can result in increased danger to life, 24 health and property; public costs for flood control measures, rescue and reliefefforts; soil erosion, sedimentation and siltation; pollution of water resources, and general degradation of the natural and man-made environment. Stripping land and paving over soil increases the rate and amount of storm water runoff, and can increase flood levels. The County Zoning Ordinance regulates structural uses, wells, septic systems, storage facilities, water and sewer facilities, and renovation/restoration of structures/facilities in the floodplain. WETLANDS OBJECTIVE: Protect wetlands from inappropriate uses and recognize their value fOr maintaining surface water quality and other benefits. Non-tidal wetlands are currently regulated under the federal Clean Water Act. Section 404 of the Act requires a permit for the discharge of dredged or fill material into waters of the United States, including wetlands. The U.S. Army Corps of Engineers administers these permits. Through Section 401 of the Clean Water Act, the Virginia Department of Environmental Quality may also review and require mitigation for projects that impact wetlands and streams. Wetlands are defined as those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs and similar areas. Evidence of wetland indicators from each parameter (hydrology, soil, and vegetation) must be found in order to make a positive wetland determination. Wetlands are important for maintaining surface water quality. Other benefits include erosion control, flood reduction, spawning areas, groundwater recharge areas, and wildlife habi- tats. The County regulates wetlands associated with perennial streams through the Water Protection Ordinance. Evidence that all applicable state and federal permits have been obtained is required by the County as part of the development review process. Strategy: Continue to coordinate County development review with state and federal wetland regulations. Strategy: Encourage the voluntary protection of wetlands not required by regulation through conservation easements and deed restrictions. MOORMAN'S RIVER "EXCEPTIONAL WATER" DESIGNATION OBJECTIVE: Continue to protect the M[~orman's River exceptional environmental setting, aquatic community and recreational opportunities. Virginia Water Quality Standards allow designation and protection of surface waters which provide exceptional environmental settings and exceptional aquatic communities or exceptional recreational opportunities. The State standards for "exceptional water,"effective May, 1992, were adopted to comply with the federal anti-degradation regulation implementing the Clean Water Act. Waters that are designated under this regulation are to be maintained and protected to prevent permanent or long-term degradation or impairment. No new or increased discharge of sewage or industrial wastes will be allowed into waters designated under this category, but water withdrawals will be allowed. 25 The Board of Supervisors, in February, 1993, endorsed a citizen petition to designate the Moorman's River as an exceptional water from its headwaters in the Shenandoah National Park, including its North and South Forks, to its confluence with the Mechum's River near White Hall. Following public comment, the Virginia Water Control Board recommended going forward with the nomination. The designation is currently pending.. This designation would be consistent with County efforts to protect the quality of water that flows to public drinking water reservoirs. Sugar Hollow Reservoir is at the confluence of the Moorman's North and South Forks. The Moorman's River flows eventually to the South Fork Rivanna Reservoir. The Moorman's is designated both a County Scenic stream and a State Scenic River from the Sugar Hollow Reservoir to the Mechum's River. County residents have voluntarily established conservation easements and two agriculturaVforestal districts along the banks of the Moorman's. The North and South Forks are designated natural trout streams by Department of Environmental Quality. During some summer dry periods, water in the Sugar Hollow Reservoir can drop below the crest of the spillway. As a result, a section of the Moorman's River downstream can experience very low flow conditions, which may be detrimental to aquatic communities. The Sugar Hollow Dam does not have a minimum release requirement because the structure predates state regulations pertaining to minimum instream flow. Water demand from the Sugar Hollow Reservoir, especially in the summer months, causes increases in the frequency and duration of low flow conditions in the Moorman's River. Conservation measures discussed on page -- are necessary' to help reduce the demand on the Sugar Hollow Reservoir, but may not alone solve the problems of low flow in the Moorman's River. Strategy: Work with the Rivanna Water and Sewer Authority and appropriate state agencies to balance water supply needs with minimal streamflow requirements for the Moormans River in Sugar Hollow. RIVANNA RIVER BASIN PROJECT The Thomas Jefferson Planning District Commission (TJPDC) sponsored the Rivanna River Basin Project, including a citizens' Rivanna Roundtable, basin land cover analysis and citizen monitoring (in conjunction with the Environmental Education Center). The project has culminated in a series of recommendations for the Rivanna River basin, a report that outlines the current state of the basin, and desired future conditions for the basin. Recommendations include: (1) Develop a Corridor Plan; (2) Establish a knowledge base; (3) Establish a resource organization; (4) Develop community design practices; and (5) Expand stewardship. Plans are underway to c. ontinue the citizen roundtable in some format and to continue the strong foundation of citizen monitoring that was established during the year-long project (October '96 through December '97). The Rivanna River is a designated state Scenic River from the Woolen Mills Dam (at the Moores Creek confluence) to the confluence with the James River in Fluvanna County. Strategy: Review and implement recommendations of the Rivanna River basin project as appropriate. Strategy: Provide assistance to the Thomas Jefferson Planning District Commission and the Environmental Education Center to continue citizen monitoring efforts in the Rivanna Basin. 26 AGRICULTURAL AND FORESTRY BEST MANAGEMENT PRACTICES OBJECTIVE: Encourage BMP's to reduce nonpoint source pollution from agricultural and forestry uses. The importance of public education to insure the Cooperative efforts of individual property owners has previously been noted as a major water resource protection su'ategy. Another major voluntary strategy for surface water is the encouragement of Best Management Practices (BMP's). BMP'S were discussed under Agricultural and Forestry Resources, page --. Voluntary Best Management Practices are the best method to reduce non-point source pollution from agricultural and forestry uses since those uses cannot be easily regulated. The Thomas Jefferson Soil and Water Conservation District, the Virginia Department of Forestry, and the Agricultural Stabilization and Conservation Service administer cost-share programs. The Agricultural Stewardship Act was adopted by the General Assembly in 1996, and took effect on April 1, 1997. The Act provides a formal mechanism for agricultural water quality complaints to be investigated, and plans developed and implemented to remedy actual problems (the Act is known informally as the "Bad Actor" law). The program is administered by the Virginia Department of Agriculture and Consumer Services (VDACS). The Thomas Jefferson Soil and Water Conservation District (TJSWCD) will be active in investigating many of the complaints and developing conservation solutions to identified problems. At present, state-level and TJSWCD staffto implement the Act is very limited. Implementation of the Act is likely to require more staff resources. Strategy: Make technical and financial assistance to implement Best Management Practices projects more readily available to the public through appropriate departments and agencies. [Fork with TJ$IVCD to promote participation in cost-share programs. Strategy: }Fork with TJSgFCD to respond to and help resolve agricultural water quality issues raised by the /lgricultural Stewardship/1 ct. 27 SURFACE WATER STANDARDS The following GENERAL STANDARDS should be applied to protect surface water: Protect and enhance riparian corridors in their natural condition. Maintain natural buffer areas for all land uses. Buffer areas reduce erosion and runoff of sediment, nutrients, and pesticides from land activities adjacent to watercourses; provide stream bank stabilization by maintenance of live root systems; maintain temperature norms along watercourses; and maintain shoreline and aquatic habitats. Maintain along all watercourses buffers of undisturbed natural or established vegetation, or replanted buffers with the goal of an indigenous bottomland forest. Stream buffer widths should be adjusted based on the presence of wetlands, flood plains, adjacent critical and/or erodible slopes, guidance from the Open Space Plan, and other watershed considerations. Avoid placing fences, bridges, and other impediments across canoeable streams. Property owners should be encouraged to remove fallen trees and other obstacles to canoe and boat passage on streams commonly used for boating and canoeing. As development occurs, design development and asociated BMPs to reduce impervious cover and to minimize negative impacts on streams, including stream channel erosion, habitat degradation, and loss of groundwater recharge. Undertake ecosystem restoration projects in high priority areas. The following GENERAL STANDARDS should be used in flood hazard areas: Locate and design utilities such as gas lines, electrical, and telephone systems to minimize damage and prevent flotation and dislocation due to flooding. Require storm water detention facilities for developments with high impervious coverage and design such facilities to maintain pre-development runoffrates for the 2-year and 1 O-year storms. Encourage regional and subregional stormwater detention facilities that can serve as BMPs and that can serve more than one individual development. Utilize floodplains for their natural ability to assimilate floodwaters. Appropriate uses include passive recreation, greenbelt development, buffer areas, and open space. Restore natural floodplain functions where they have been altered. Plant appropriate floodplain vegetation as part ofa BMP and buffer program. Encourage and promote landowners to put floodplains into conservation easements. 28 Surface Drinking Water OBJECTIVE: Protect the availability and quality of surface drinking water supplies. Surface drinking water supply resources for Albemarle County include six impoundments and one river intake structure. The South Fork Rivanna River Reservoir, Beaver Creek Reservoir, and Sugar Hollow Reservoir are located in the South Fork Rivanna River watershed. Ragged Mountain Reservoir is located in the Rivanna River watershed. The Totier Creek Reservoir is located in the James River watershed. Chris Greene Lake is located along Jacob's Run in the North Fork Rivanna River watershed. A river intake structure is located in the North Fork Rivanna River. The North Fork Rivanna Riverwatershed is the only water supply watershed which contains significant acreage (sixty-nine square miles) outside of Albemarle County. (See the Land Use Plan Chapter, Public Water and Sewer section for additional information; page 109). Albemarle has since 1972 enacted and enforced measures to protect the watersheds of the public water impoundments within the County and has successfully defended these measures in litigation. Urban and suburban development in water supply watershed areas causes the degradation of water quality through runoff from development activities, and conflicts with water quality protection efforts. Therefore, it has been a County policy to restrict development in water supply watersheds and to discourage the location of public facilities such as public sewer and water lines and major roads. The policy of protecting the environmental integrity of these watersheds will continue to be an important component of this Comprehensive Plan. Water supply protection is one of the six major elements that form the basis for the Rural Area concept. The County's Rural Area plays a crucial role in water supply protection, including protection of surface drinking water impoundment watersheds and protection of groundwater supplies for the Rural Area population. The maintenance of pasture and especially forestry areas is generally beneficial to water quality. HoWever, some agricultural and forestry activities in the Rural Areas, such as livestock access to streams, chemical use, irrigation, and animal waste storage or application may also conflict with water supply protection objectiws. ~Pollutants including sediment, nutrients, pesticides, and herbicides may be introduced into streams and rivers. Efforts can be made, however, to mitigate such conflicts. The County, in pa. rtnership with the Thomas JefferSon Soil and Water Conservation District and the Virginia Department of Forestry, promotes the adoption of best management practices for agricultural and forestry activities. (SeeAgricultural and Forestry ResOUrces section, page --.) WATERSHED MANAGEMENT PLANNING Surface water supply protection has been a special concern in Albemarle County since 1972 when the City and County adopted a joint resolution forming the Rivanna Water and Sewer Authority. In November, 1973, the Authority appointed an advisory committee to study the reservoir pollution problem. In 1975 a study of the South Fork Rivanna Reservoir was undertaken by Betz Environmental Engineers, Inc. for the Rivanna Water and Sewer Authority. This study recommended the implementation of a comprehensive watershed management plan that included reservoir management, water treatment modifications, point and non-point source controls, and routine watershed monitoring. The 1977 report resulting from this initial study, Water Quality Management Study of the South Rivanna Reservoir and Tributary ~lrea by Betz Environmental Engineers, Inc., provided the basic guidelines for future measures taken to provide water supply protection in the area. The first step toward implementing the recommended watershed plan was taken by the Albemarle County Board of Supervisors in September, 1977, when they adopted a Runoff.Control Ordinance applicable in all water supply impoundment watersheds (see Map -). The purpose of this ordinance was to protect against and minimize the pollution and eutrophication of the public drinking water supply impoundments resulting from land development in the watershed areas. 29 ALBEMARLE COUNTY.

In July, 1977, a Report on Alternative Water Supply Sources prepared by Camp, Dresser & MeKee, Inc. was published. It concluded that the only viable alternatives were: (1) expansion of the South Fork Rivanna Reservoir by the addition of flashboards; (2) development of the Buck Mountain system as a supplement to the South Fork Rlvanna Reservoir; and, (3) development of the James River and abandonment of the South Fork Rivanna Reservoir. This study reaffirmed the importance of protecting the South Fork Rivanna Watershed. In 1978, the Board of Supervisors rezoned all publicly owned properties except school sites within water supply watersheds to a conservation district designation. In August, 1979, a second study was completed; the South Rivanna Reservoir Watershed Management Plan was prepared by F. X. Browne and Associates, Inc. and the Watershed Management Plan Committee, made up of representatives of agencies and interest groups involved with water supply in Albemarle and Charlottesville. The report recommended: (1) creating the position of a Watershed Management Official; (2) eliminating major point source discharge; (3) that the Virginia Department of Transportation install and maintain erosion and sedimentation control measures as specified in its manual; and, (4)integrating watershed management goals into agricultural, technical, and financial assistance programs. After 1979, significant efforts were made to deal with watershed pollution problems. A $5.8 million sewer interceptor was constructed from the Moore's Cl:eek interceptor to Crozet. This allowed for collection of sewage in Crozet through a public system, eliminating several major point discharges and failing septic systems. A $5 million sewage collection system was completed in Crozet. To alleviate non-point discharge from the Crozet Community, the Lickinghole Creek Sedimentation Basin was completed in 1994. In 1980, growth area land use plan amendments to the 1977 Comprehensive Plan were adopted which removed all land from the Urban Area also located in the South fork Rivanna watershed. In August, 1980, a moratorium was enacted on development in the proposed Buck Mountain Creek impoundment watershed. It remained in place until agreement was reached between the City and County regarding the extent of land necessary to be purchased for the potential future impoundment and the means of financing the purchases. In December, 1980, a comprehensive rezoning of the County placed major limitations on development in the Rural Areas. Special use permit criteria addressed proposed developments located within water supply watersheds. A 1982 revision to the Plan removed watershed properties from Growth Areas in Crozet, Scottsville, Earlysville, and Ivy, These properties, containing over 1,000 acres, were rezoned to Rural Areas the following year. Crozet and Ivy, both located entirely in water supply watersheds, were scaled back in size. In Crozet, the Growth Area was planned to drain into the Liekinghole Creek Sedimentation BaSin. In 1982, a Section 208 Watershed Management Study of the South Rivanna Reservoir was completed by F. X. Browne and Associates, Inc. The study concluded that the watershed plan developed in. 1977 and refined in 1979 was still valid and should be fully implemented. A Report on the James River prepared by the Rivanna Water and Sewer Authority in 1982 updated the 1977 study of alternative water supply sources. It concluded that the quantity of water in the James River is more than adequate, but the cost of supplying the City of Charlottesville with water from the James River was over $20 million (1982 dollars) greater than the Buck Mountain Reservoir alternative. A recent watershed activity was a Phase II EPA Clean Lakes project federally funded to implement agricultural and highway Best Management Practices projects in a portion of the South Fork Rivanna watershed. The final report from the Phase II project was completed by F.X: Browne in April, 1993. The report recommends further 31 monitoring on the South Fork Rivanna Reservoir and for the new Lickinghole Creek facility. The report also reiterates the validity of the Section 208 Watershed Management Study. In November, 1994, Black & Veatch prepared the Urban Raw Water Management Plan for RWSA to prOVide and update information for planning, permitting, and implementing additional raw water supplies to the year 2040. Three memoranda were prepared regarding the Buck Mountain Reservoir Evaluation Update, South Rivanna Bathymetric Study, and Feasibility of Flashboards on the South Rivanna Dam. The plan reports that the RWSA's projected average daily demand in the year 2040 for the urban area will be 18.7 million gallons per day (mgd). Current sources are capable of supplying only 10.1 mgd in year 2040 to satisfy the average daily demands. A deficit of 8.6 mgd is anticipated by year 2040. Additional supplies must be on-line by year 2015 to meet the average daily demands of the Charlottesville Urban Services Area. PLANNING FOR THE FUTURE WATER SUPPLY The Rivanna Water and Sewer Authority (RWSA) has retained the firm' ofVanasse Hangen Brustlin, Inc. (VHB) to assist with the task of future water supply permitting. The permitting process must identify and evaluate all realistic sources of water for the community. The study has produced to date a water needs analysis for the urban system consisting of a Demand Analysis report and a Supply Analysis report. These reports update the figures provided in the Black & Veatch study. According to the reports, water demand in the year 2050 is projected to be between 18 and 21 mgd. Current safe yield (the amount of water the system can supply during a drought of historic record) is between 11.9'and 12.6 mgd, and is expected to decrease to between 4.5 and 4.8 mgd in the year 2050 based on current water supplies. Based on data provided in these repons, additional supplies may be needed sometime before 2015 if the area were to experience a drought similar to the drought of record used in the analyses. Current and future goals of the study involve identifying possible water supply alternatives, developing criteria to evaluate the alternatives (e.g., feasibility, environmental impacts), narrowing the list of alternatives based on the evaluation, and, ultimately, selecting a preferred altemative and promoting this to the state and federal agencies responsible for water supply permitting. The previously-proposed Buck Mountain Reservoir is one of the available alternatives that will be considered in the present study, along with other alternatives, such as flashboards on the South Fork Rivanna Reservoir, dredging the South Fork Rivanna Reservoir, obtaining water from the James River, water conservation, and any other alternatives that will be identified in the study. The discovery of the James spineymussel, a federally-listed endangered species, in Buck Mountain Creek will be one of the factors considered in the.evaluation of alternative supplies. DEVELOPING A WATER CONSERVATION/EFFICIENCY PROGRAM OBJECTIVE: Support water conservation and use efficiency measures to prolong the life of existing and future water supplies. Water conservation and efficiency of water use will be strong factors considered in the future water supply permitting process. The permitting agencies will require this analysis as part of the future water supply permitting process. While the permitting process is likely to drive this analysis, the principles listed at the beginning of this chapter suggest that water conservation and efficiency are important overall objectives for water resources management in the County and the region. Water conservation and use efficiency measures have the potential to prolong the life of existing and future water supplies, which~ is important for economic, ecological, and ethical reasons. Water conservation affects the demand on the Sugar Hollow Reservoir, for example, which in turn impacts the amount of instream flow in the Moorman's River, page --. 32 Many activities related to water conservation and efficiency will be directed by the Albemarle County Service Authority and City of Charlottesville (Public Works Department) as measures that are implemented by those suppliers based on the characteristics of their respective customer bases. Other measures, if implemented, will require a stronger role for the County, such as providing for the use of drought-tolerant landscaping (xeriscaping). The Rivanna Water and Sewer Authority will play a key supporting role in designing and implementing any water conservation or efficiency measures. To that end, a Citizens' Advisory Committee, · appointed by the RWSA Board of Directors, began meeting in February 1998. One of the initial tasks assigned to this committee is to work with the RWSA Board and staff on water conservation issues. Current water conservation efforts of the Albemarle County Service Authority include leak surveys, funding for a water conservation curriculum in schools, conservation information for new customers, speakers~ bill inserts, public service anouncements, and leak trouble-shooting for customers. Also, some measures can be implemented during emergency drought conditions. Additional measures ultimately chosen for implementation will be evaluated by the current Vanasse Hangen Brustlin, Inc. (VHB) study and other related efforts. Some of the potential measures include: Water conservation devices for new construction. Water conservation devices retrofit into existing structures, beginning with institutional buildings. Additional public education materials inserted with water bills and through other media. pOssible reuse of certain waste streams for landscape maintenance and other non-drinking water uses. Use ofxeriscaping (drought-tolerant landscape design). Utility rate restructuring. Mandatory water conservation during dry periods. Strategy: Support the Albemarle County Service Authority, City of Charlottesville, and Rivanna Water and Sewer Authority to develop a water conservation and efficiency program through the future water supply permitting process. Implement recommended measures that require County action through regulatory or non-regulatory programs. NORTH FORK WATER SUPPLY/CHRIS' GREENE 'LAKE OBJECTIVE: Use Chris Greene Lake to supplement water supply to the North Fork Systert~ Chris Greene Lake on Jacob's Run was constructed in 1967-68 to provide a drinking water supply~' In 1970, the Board approved the recreational development of the lake. Chris Greene Lake can be used to enhance the water supply to the North Fork Rivanna water supply inta~ke and water treatment plant. The Chris Greene Lake watershed is part of the larger North Fork Rivanna watershed for the Nb~h,F0rk Ri~anna' iniake. The N0rfli Fork Rivanna watershed is not currently subject to the runoff control ordinance.' ' Black and Veech completed the Urban Raw Water Management Study in November, 1994, for the Rivanna Water and Sewer Authority (RWSA). An addendum to the report outlined the possibility, based on computer models, of augmenting the safe yield of the North Fork water system by using supPlemental releases of water froTM Chris Greene Lake. According to the studY, the North Fork system could increase its'safe yield ~r6~i hiiiiion gali6ns per day to approximately 2 million gallons per day, which is the current treatment capacity of the North Fork plant. Black and Veech also predicted that supplemental releases would not measurably affect the recreational use of Chris Greene Lake. The Virginia Department of Health has provided preliminary comment to RWSA that continued use of Chris Greene Lake for recreational purposes during SUpplemental 'releases would be acceptable, since the water intake is a mile downstream in the North Fork Rivanna River. 33 Chris Greene Lake is now designated as a supplemental water supply to the North Fork system. In addition the lake's watershed is now protected with the same measures 'utilized in other drinking water watersheds through designation in the Water Protection Ordinance. Continued recreational use of the lake should be pursued through coordination with the County's Parks and Recreation Department, RWSA, and the Virginia Depas~is~ent of Health. Applying watershed protection measures to the entire North Fork Rivanna River watershed above the water intake should be considered and evaluated. Cooperative agreements with Greene County for watershed protection should be pursued. Strategy: Continue the recreational use of Chris Greene I, alee. Strategy: Pursue a cooperative agreement with Greene County to protect the North Forh Rivanna watershed RECREATIONAL USE OF WATER SUPPLY AREAS OBJECT/V-E: Allow and manage recreational uses of drinMng water reservoirs and adjacentpublic land only as incidental uses to the primary function of water supply and in such a manner as to prevent cumulative impacts that may impair that primary function. The water supply reservoirs and adjoining land are used for various active and passive recreational purposes. These uses are considered incidental to the reservoirs' chief function of providing a source of public drinking water. While the demand for recreational uses is increasing, it is imperative that their cumulative impact does not pose a threat to water quality and water supply functions. Sections 14-7 through 14-23 of the Albemarle County Code contain some regulations for recreational use of waters owned or controlled by the County and use of water supply reservoirs managed by the Rivanna Water and Sewer Authority. The regulations pertain to boating (prohibition of internal combustion engines in most cases), prohibited uses on reservoirs (swimming, hunting, camping, and other uses specific to each reservoir), vehicular traffic, and hours of operation. Section 14-20 states that permits pertaining to recreational use of reservoirs and reservoir land addressed in the Code are to be administered by the Rivanna Water and Sewer Authority. Beaver Creek Reservoir, Totier Creek Reservoir, and Chris Greene Lake are managed for public fishing and picnicking by the Parks and Recreation Department. Chris Greene Lake also has a public swimming beach. The South Fork Rivanna Reservoir is utilized for competitive and community rowing by University of Virginia- affiliated and community rowing organizations. The South Fork Reservoir is also used extensively for fishing and canoeing. Two boat ramps currently exist (South Fork Rivanna Water Treatment Plant land and the Route 676 bridge), although fishing and boating access at these sites is accepted rather than actively managed for these uses. Upgrading and active public management of the boat launch at the water treatment plant, as well as components of a greenway trail, are planned future uses for the South Fork Rivanna Reservoir. The Ivy Creek Natural Area with hiking trails is located adjacent the South Fork Rivanna Reservoir. The Ivy Creek Foundation is also developing a system of hiking trails on land surrounding the Ragged Mountain Reservoir, which is currently utilized for limited fishing and boating. Finally, the land adjacent to and upstream from the Sugar Hollow Reservoir, owned by the City of Charlottesville and Shenandoah National Park, is heavily used for hiking, fishing, and mountain biking. It is evident that recreational use associated with water supply reservoirs has evolved as a patchwork quilt of formal, informal, and historical uses rather than a set of deliberate practices guided by a cohesive policy (other than the uses addressed in the County Code and those sites already managed as County parks). Experience has '34 shown that, in a heavily used area, well planned and managed recreational access has fewer environmental and water supply impacts and is safer than the de facto, unmanaged access characteristic of, for instance, the Route 676 boat ramp and much of the activity above Sugar Hollow Reservoir. In addition, the County is better able to manage and limit the intensity of recreational uses than a private organization would be. As recreational demand increases in, or adjacent to, water supply reservoirs, it will be necessary to adhere to a policy that, most importantly, provides for the continued protection of reservoirs and adjacent public land for their principal water supply function. At the same time, the policy should allow for the evaluation of competing recreational demands, and the restoration of areas previously degraded from over-use. Decisions regarding recreational uses on reservoirs should also be consistent with the Growth Management policy. The strategy listed -below should be an action item given recent increases in demand for recreational use of reservoir areas. Strategy: The County should take a lead role in developing a recreation and water supply protection plan for each reservoir to address incidental recreational uses of drinking water reservoirs and adjacent public land. This effort should be coordinated with the Rivanna }Fater and Sewer Authority, the City of Charlottesville, Shenandoah National Park, and other relevant agencies. STATE-LEVEL PUBLIC WATER SUPPLY PROTECTION All of the water supply impoundments are protected by a public water supply (PWS) designat.ion by the Virginia Department of Environmental Quality (DEQ). In addition, the North Fork Rivanna River is designated a PWS for a distance of five miles above the intake at Piney Mountain. The Rivanna River is designated a PWS within Albemarle County for a distance of five miles above the Lake Monticello raw water intake in Fluvanna County. The PWS designation means that additional water quality standards are applicable to both the water supply stream and its tributaries for a designated distance upstream from the water intake. The Department of Environmental Quality enforces the standards through its discharge permit programs for point source discharges. The PWS designation is important for the North Fork Rivanna River intake for two reasons. Because the intake is located on a free flowing stream and not an impoundment, the watershed is not currently protected by the Runoff Control Ordinance. Also, most of the watershed lies in Greene County. Therefore, development could occur outside of Albemarle's jurisdiction which would have an impact on the North Fork Rivanna water supply. The PWS designation does not address nonpoint source pollution, which is the major source of pollution in the North Fork Rivanna watershed. VOLUNTARY PROTECTZON MEASURES OBJECTIVE: Encourage voluntary techniques to protect drinking water supplies. Agricultural/forestal activities may cause conflicts with water quality objectives in a water supply watershed. Since most agricultural/forestal uses cannot currently be regulated to help protect water resources, voluntary techniques are very important. Best Management Practices have been used effectively in a recent Phase II EPA Clean Lakes cost-sharing program. This program has corrected some of the major agricultural runoff problems. Remaining funds will be used for stream bank erosion control and reservoir monitoring. Conservation plans which are prepared for farmers by the Thomas Jefferson Soil and Water Conservation District or the Natural Resource Conservation Service are a valuable voluntary tool. If conservation plans were required as a condition for the land use value tax program, then they could become a more effective technique to reduce agricultural or forestal runoff. Soil and water conservation plans have been prepared by Thomas Jefferson Soil and Water Conservation District (TJSWCD) for agricultural lands adjacent to perennial streams when Resource 35 · Protection Area (RPA) buffer reductions have been requested and approved. Strategy: Investigate available sources andprovide complete funding to implement high Priority BMPprojects in water supply watersheds. Develop a prioritization method to identify high Priorityj~rojects. Technical as- sistance to implement BMP projects should be made more readily available to the public by appropriate departments and agencies. Strategy: RevieW the Code of Virginia to determine where the County can suggest changes to allow for local discretion in requiring conservation plans. SURFACE DRJNIONG WATER STANDARDS The following GENERAL STANDARDS should be applied to protect surface drinking water, in addition to the standards in the Surface Water section: Maintain natural buffer areas of at least 100 feet along all streams in the watershed to establish a continuous stream buffer network. Review and comment on State and federal agency activities in the watershed, including 'activities of Virginia Department of Transportation, to encourage water supply protection. Apply a general ri.sk management approach to the watershed whereby the elimination of risk through land use management ~s given the highest priority, and reduction of risk through design and BMPs is given second priority. Undertake ecosystem restoration projects where appropriate. Maintain high water quality standards for agricultural and forestry land through conservation plans and good stewardship practices, as recommended by the Thomas Jefferson Soil and Water Conservation District, Natural Resources Conservati6n Service, Virginia Department &Forestry, and other appropriate agencies. 36 Groundwater INTRODUCTION OBJECTIVE: Protect the availability and quality of groundwater resources. Groundwater Use In Albemarle County Groundwater protection is important in Albemarle County due to the dependence of a large and growing Rural Area population that relies on this source for its water needs. While all of Albemarle County's major public water supplies are surface water sources, approximately 12,600 households in the County (43% of all County households) rely on private, individual wells, and many other County residents rely on water from small, private, groundwater-dependent water systems. Many businesses, industries, schools, and recreational and cultural sites also utilize groundwater for water supply. Whether the use is residential, commercial, industrial, or recreational, groundwater-dependent systems must be protected. Once a supply is lost through overpumping or contamination, replacement of the supply is usually very costly, and is even infeasible in some cases. A major concern to the County is that groundwater quantity or quality problems may occur in the Rural Areas~ where no extension of public utilities are planned or are not economically feasible to provide. In addition, groundwater supplies "recharge" surface streams. Polluted groundwater can become polluted surface water. For these reasons, groundwater has become a resource of increasing importance in Albemarle County, especially as an expanding population in the rural areas is dependent upon and can adversely impact the quantity and quality of groundwater. Planning and Authority For Groundwater Protection Groundwater protection is expressly included as an element and purpose of comprehensive plans in Sections 15.2 - 2224 and 2225 of the Code of Virginia, and zoning ordinances in Section 15.2'2283. In addition, Section 32.1- 176.5B allows Albemarle to require testing of water quality prior to issuance of a building permit. Protection of groundwater is currently provided for under the 1973 Virginia Groundwater Act. The main purpose of this law (Code of Virginia Sections 62.1-44.83 - 44.187) is to preserve the quantity of groundwater available for use. It allows the State Water Control Board to designate special areas for the management of groundwater supplies. (The Eastern Shore and the southeastern Tidewater area ~e currently designated.) Groundwater is also protected under the Virginia Water Control Law (Code of Virginia Sections 62.1-44.2 - 44-34:7). This law creates an anti-degradation policy which protects existing high,quality state waters (both ground and surface waters) and restores other state waters to a quality sufficient for all reasonable public uses. A County effort to protect groundwater can employ a series of tools, in order of priority for implementation as listed below: Information gathering on the nature of the resource and how to best plan the location and amount of development that is dependent on groundwater. Education and outreach for voluntary action to prevent the depletion and degradation of groundwater. Regulatory measures through zoning and other ordinances to protect wellheads and ensure adequate groundwater quantity and quality. In 1990, the County developed the Groundwater Protection Study to provide a framework for a County groundwater program. (See Groundwater Protection Study, p.--.) The Water Resources Committee evaluated and updated thig study in 1993, and made recommendations regarding implementation. One of the suggested implementation measures, a pilot groundwater study, was conducted in the North Fork/South Fork Hardware River 37 Watershed in 1993-94. Additional recommendations resulting from that study were very similar to those set forth earlier by the Water Resources Committee. Using procedures from the pilot study, a 'County-wide program of household water quality education, including voluntary testing and diagnosis of 497 wells, was conducted during the summer of 1995. When the Groundwater Protection Study was adopted in 1990, responsibility for program implementation was assigned to the Water Resources Manager. This position is primarily responsible for drinking water watershed programs, source water monitoring and protection for the Rivanna Water and Sewer Authority, stormwater management, and implementation of the County's str6am bUffer program (see the previous Sections on Surface Water and Surface Drinking Water). Due to the nature of these priorities, only 10% of the position can be assigned to developing a groundwater program. The implementation of the groundwater program envisioned in this Comprehensive Plan will require additional staff resources to accomplish the task. Strategy: Address staff resources needed to implement the groundwater progratt~ Strategy: Create a groundwater subcommittee of the Water Resources Committee to implement strategies identified in this Plan. Strategy: Continue coordination by relevant agencies of groundwater and surface water programs. HYDROGEOLOGIC SETTING HYdrologic Cycle Precipitation is the source of groundwater in Albemarle County. The average annual precipitation at Charlottesville is 45 inches, of which about 30 inches returns to the atmosphere through evapotranspiration, 10 inches becomes surface runoffand 5 inches recharges the groundwater. Over a number of years, the groundwater igsain balances with the groundwater lost to Wells and inflow to Streams or springs. But when winter precipitation below normal, or summer drought conditions occur, shortages may occur in the warmer months when increased evaportranspiration and inflow to streams cause the groundwater levels to fall. Geology Albemarle County consists primarily of metamorphic and igneous rocks overlain by a "regolith" layer composed of soil, saprolite or weathered bedrock, and alluvium from streams. Groundwater is stored in the pore spaces of the regolith and in fractures of the underlying bedroCkl Fractures are the usual source of well water, since most wells are cased tothe depth of bedrock to prevent surface contamination. Fractures decrease with depth, and most occur within one hundred feet of the top of the bedrOck. The 'greater the nUmber of fractures in the rock aquifer penetrated by the well, the greater the well yield. 'The occurrence of groUndwater resources is related to the physiographic provinces (regions of similar geologicai structure and climate with characteristic sets of land forms). Albemarle is located within two such provinces, the Piedmont Province and the Blue Ridge ProvinCe (see Map --). The Piedmont Province includes approximately that portion of the County east of a line through Batesville, Crozet and Free Union. The area to the west is in the Blue Ridge Province. Piedmont Province The regolith in the Piedmont Province averages fifty feet in depth but may be as much as one hundred feet deep on upland rims. Well yields generally range from 3-30 gallons per minute,_although many yields are below 3 gpm. 38 Basin riassic Basin OF i ~COTTSVILLE ALBEMARLE COUNTY, VIRGINIA GROUNDWATER I Province Boundary Triassic Basin Areas SCXJRCES: PNYSIOGRARNIC PROVINCES OF VIRGINIA A GROUNOWATER PROTECTION STRATEGY FOR VIRGINIA PREPARED BY THE VIRGINIA GROUNDWATER PROTECTION STEERIN GROUND WATER MAP OF VIRGINIA, ~EPARED BY: ,partrnsn~ o~ P~nn~n~ an~ community D~v~oprn~n~ · O~c~ o~ ~apP~n~,~aph~¢s ~n~ ~n~orm~t~on R~sourc~s (00~A~R) There are two areas of sedimentary rocks located in the Piedmont area of Albemarle. The larger area is located west of Scottsville, and a small area is located near the Orange County line. Beds of sandstone and conglomerate in these Triassic basins provide fair to moderately good aquifers. The yield of wells in sedimentary rocks generally increase with depth. The quality of groundwater in the Piedmont is affected by the chemical composition of the regolith and bedrock, and by man-made contamination. Groundwater from crystalline rocks is generally softer, more acidic and lower in dissolved solids than water from sedimentary rocks. Deep wells in sedimentary rocks may have excessive dissolved solids (especially sulfates). Problems with iron and manganese, staining and taste, occur in sedimentary and dark-colored crystalline rocks. Acidic water is common in the Piedmont Province, and can corrode copper water lines. Nitrates in Iow concentrations occur naturally in groundwater, but higher levels indicate contamination from fertilizer, animal waste or septic tanks. Blue Ridge Province In the Blue Ridge Province, well yields are generally lower (less than 20 GPM) than the Piedmont Province. The most favorable areas for groundwater accumulation are the lower slopes of the mountains where runoff is abundant. Water quality is good due to the relatively insoluble rocks. Iron content is high in some areas. Potential for man-made contamination is high, due to the shallow depth of the regolith. GROUNDWATER SOURCES Private, Individual Water Supplies f , As noted earlier, approximately 43% o Albemarle s 29,307 households (approximately 12,600 households) utilize private, individual water supplies for household water. This makes private, individual supplies the most widely used groundwater source in the County, and one that is critical to protect for the health and welfare of the rural areas population. The following private, individual supplies are utilized in Albemarle County: 1) 2) 3) Drilled Wells: Drilled wells constitute the large majority (approximately 88%) of private, individual supplies in use in the County. Drilled wells are usually drilled down through the bedrock and utilize water from fractures in crystalline rock (in the Piedmont and Blue Ridge provinces). For this reason, drilled wells are less vulnerable to surface contamination than either bored or dug wells (see below). Most drilled wells in the Piedmont are between I00 and 350 feet deep, and yield 1 to 20 gallons per minute (although higher yields are possible). Well yield is dependent on site-specific factors, such as terrain and fracture density, and on regional factors, such as bedrock and surficial geology and regional flow pathways. Bored and Dug Wells: Bored wells (approximately 6% of individual supplies) usually penetrate to or just below the bedrock/saprolite interface (most are 30 to 100 feet deep), and utilize water from near- surface aquifers, often in the saprolite. Dug wells also utilize these near-surface sources. For this reason, bored and dug wells are much more susceptible to surface influence than drilled wells. Correspondingly, the likelihood of bacteria, nitrate, petroleum, or other contamination is higher in bored and dug wells. Yields in these shallow wells are often higher than those for drilled wells. Springs: Some households (approximately 5% of individual supplies) utilize springs for drinking water. Springs appear in places where the water table intersects the land surface, particularly near the bottom of valley side-slopes. In many eases, there is a direct connection between surface water and springs. Therefore, springs are easily contaminated with sediment, bacteria, and any chemical used near the 40 springhead. 4) Other: Cisterns, Surface Water: A small number of households (approximately 1% of individual supplies) may utilize other types of water supplies, including cisterns. These supplies are probably not reliable from either a water quantity or quality point-of-view. Once a private, individual supply receives a permit from the Virginia Department of Health and is constructed, there is no governmental oversight over the management of these systems. This makes private, individual systems the most decentralized and least regulated water supply resource in the County. For this reason, the owners and users of these systems should understand and exercise the stewardship principles necessary to protect their own water supply and those of their neighbors and communities. (See Groundwater Education p.--) Strategy: Facilitate, make available, and help fund programs for the testing of private, individual water supplies. County-Designated Central Wells The current policy; adopted in 1976, requires approval from the Board of Supervisors and monitoring by the Engineering Department for wells serving three or more connections, as outlined in Chapter 10 of the Code of Albemarle. There are specific pump test and yield standards that must be met. Also, the Board of Supervisors passed a resolution in February, 1993 that central systems should be carefully evaluated, and approved systems built to Albemarle County Service Authority specifications if requested bythe authority. No formal review of the central well policy has been undertaken. The concerns with central wells are as follows: 1) Public utility status is available for central well systems with 50 connections or more. Such a designation prevents the system from being condemned and management responsibility taken over by the Albemarle County Service Authority or another entity. 2) Current and potential water treatment and testing regulations of the Safe Drinking Water Act make operation of central well systems potentially very expensive (potential new regulations concern testing for radon and mandatory disinfection of groundwater systems). An important issue for the County to consider is the County's potential liability if central systems are approved, and operators are subsequently unable to manage water quality, quantity, and/or treatment problems. The Albemarle County Service Authority does not favor any further proliferation of privately operated central systems. Local experience has shown a likelihood for central well systems to be acquired and operated by the Albemarle County Service Authority due to system failure or inadequacy. Such conversions can be expensive, especially if the original system was inadequately designed. 3) Central well systems may allow a parcel or parcels to be developed at a higher density versus that which could be achieved with individual wells. While increasing density may have some project-level advantages for cluster-type designs and preserving open spaces, these advantages must be balanced against the overall demand for groundwater supplies on a regional scale and the other factors listed above. Strategy: Review and update the central well policy and testing requirements for new central well systems. 41 See Water Service to the Rural Area, page 122 of Land Use Plan: Recommendations for Water Service to the Rural Area: · New central water systems in the Rural Area shall be strongly discouraged except for solving potable water and/or health and safety problems. · Any new central systems approved due to.potable water and/or health and safety problems must meet ACSA standards and not allow residential densities to increase beyond the density achievable with individual on, site facilities. ' State-Designated Public Wells Public water supplies, under the Virginia Department of Health Waterworks Regulations, are systems that serve over 25 people at least 60 days per year, or 15 or more connectionsl Public water supplies are divided into two category types: (1) Community and (2) Noncommunity. Community systems serve people year-round where they reside such as subdivisions or mobile home parks. Noncommunity systems do not serve a residential population, but rather establishments such as schools, restaurants, and businesses. (See Map __). Information regarding public water supplies should be maintained in a data base, including: 1) location of public systems; 2) operator of the well; and 3) well yield and depth. This effort should be incorporated into the County's evolving geographic information system, and coordinated with the ongoing effort of the Division of Mineral Resources to establish a groundwater data base. (See Groundwater Data base, p.--.) This data base will form the basis of a wellhead protection program (See p.--). Currently there are 17 community water supplies using wells and springs in Albemarle County, and 31 noncommunity systems, as listed below: 42 Public Community Water Supplies Public Noncommunity Water SuPplies 1.

Types of Groundwater Contamination Water quality constituents in groundwater can be grouped according to: (a) those that are natural by-products of geology and soils versUs those that are introduced by human activities (septic, animal waste, etc.), and (b) those that pose potential human health problems versus those that are "nuisance" problems (taste, odor, color, and/or staining problems). The following matrix categorizes the most common water quality constituents based on these considerations. pH (if metals, such as copper and lead, are leached from household plumbing by corrosive water) Iron, Manganese, Hardness, Sulfate, Total Dissolved Solids, pH, Fluoride, Corrosive Water Sodium (can be introduced by water softeners) Copper (can be leached from plumbing by corrosive water) Nitrate > 1 mg/L (septic, animal waste, fertilizers) Total Coliform Bacteria (may indicate surface influence on well) E. Coli Bacteria (septic, animal waste) Pesticides (agricultural and yard use) Other Organic Compounds (especially petroleum derivatives, such as benzene and toluene, from underground tanks and spills) Chloride (septic, road salts, fertilizer, industry, animal waste) 45 Groundwater Protection Strategy: Sources of Contamination Groundwater Protection Strategy for Virginia, published in May, 1987, was prepared under a grant from Environmental Protection Agency by the Groundwater Protection Steering Committee (comprised of state agency representatives). Among the recommendations of the report were an increased role for local governments, emphasis on public education, improved data collection, new enabling legislation, and strengthening of regulations. The report assigned top priority to five potential sources of groundwater contamination: underground fuel storage tanks, landfills, waste lagoons, septic systems, and pesticides and fertilizers. The relative importance Of these sources of contamination in Albemarle County is discussed below: Septic Systems: Septic systems are by far the most ubiquitous potential pollutant source, since approximately half of the County's households utilize this method ofwastewater treatment and disposal. This also makes septic systems a large source of recharge to groundwater and surface water. The main pollutants of concern from septic' systems are bacteriological and nitrates. Springs and shallow wells used for drinking water are the most vulnerable to septic contamination. The results from the Cooperative Extension water testing conducted in 1995 revealed that, of the 497 water sources tested, 38% of the springs and 19% of the shallow wells had positive E. coli results, while positive results were obtained for only 4% of deep wells. E. coli is an indicator of bacteriological contamination, and the likely source of most of these pOsitive results is septic systems. The state's Groundwater Protection Strategy recommends that the State Health Department'and Virginia Water Control Board (now DEQ) consider strengthening domestic sewage regulations. Albemarle County has, in the past, supplemented state regulations with additional area, slope, and setback requirements for septic systems. The County also has the authority to adopt additional regulations concerning minimal depth to rock, depth to water table, and other design considerations, but has not adopted any of these measures. Underground Storage Tanks: Underground storage tanks are also widespread across the County. The Department of Environmental Quality (DEQ) has a registration and leak detection program for regulated storage tanks, which include.commercial tanks greater than 110 gallons and agricultural/residential tanks greater than 1100 gallons used to store motor fuel. At present, there are approximately 340 registered tanks in Albemarle County. Primarily, these are used by gas stations; convenience stores; schools, commercial, industrial, and office facilities; farms, fire stations and rescue squads, and some residences. DEQ also has a program for the remediation of underground storage tanks that are confirmed to be leaking (leaking underground storage tanks, or LUSTS). At present, there are approximately 50 open LUST cases in Albemarle County that DEQ is investigating, 30 of which are potentially impacting surface water or groundwater supplies. The vast majority of tanks in the County, however, are home fuel oil tanks, and these are unregulated by DEQ. Results from the Pilot Groundwater Study indicated that 57% of respondents have a fuel oil tank at the residence, and many of these are underground tanks. In the Cooperative Extension study, 11% of participants reported that there was a home fuel oil tank within 100 feet of their well. Using the assumption that 50% of Rural Area households haVe a fuel oil storage tank, there are approximately 8,000 regulated and unregulated tanks in areas of the County where wells, and therefore groundwater, are the primary source of water supply. 46 Pesticides and Fertilizers: Pesticides and fertilizers are in wide use inAlbemarl? County for both agricultural and residential uses. Fertilizer runoffis as0urce of nutrients to local reservoirs and streams. Public education is critical to promote proper pesticide and fertilizer use and reduction. Agricultural outreach and cost-share programs -- such as those conducted by Virginia Cooperative Extension, the Thomas Jefferson Soil and Water Conse~afion District, and the Natural Resources Conservation Service -- are critical services to manage pesticide and fertilizer runoff from agricultural operations. Many of these programs include pesticide and nutrient management plans. While lawn and farm chemicals are in wide use, the County's soil and hydrogeology, characteristic of the Piedmont, may provide a degree of protection from groundwater contamination not afforded other communities, especially those in the Coastal Plain and Shenandoah Valley. The 1995 Cooperative Extension study included follow-up analysis of pesticides in "high-risk" wells (those having contamination in the first round of testing and/or proximate to orchards, crop land, and golf courses). The great majority of results were below laboratory detection limits, and none of the results exceeded EPA Health Advisory or Maximum Contaminant Levels. While pesticide contamination of groundwater cannot be ruled out, it may be that in Albemarle County, these contaminants are more readily reaching surface waters through runoff and near-surface flow than they are recharging groundwater. Landfills and Waste Lagoons: There are far fewer landfills and waste lagoons than the other sources of contamination discussed above. However, each facility may have a proportionately.greater impact on surrounding groundwater sources and groundwaterrecharge to streams. At present, there is one active landfill, the Ivy Landfill (which is scheduled to stop accepting municipal solid waste in July of 1998), and one inactive landfill, the Keene Landfill. Both are regulated by DEQ and have a network of monitoring wells that must be maintained through closure and post-closure periods. There are a small number of industrial waste lagoons in the County that do not discharge to surface water. These are either pumped out and the effluent treated at a wastewater treatment plant, or are reuse/recycle systems where the effluent is reused in the industrial process (closed-loop systems). These types of facilities are required to have a Virginia Pollutant Abatement (VPA) Permit from DEQ. In addition to septic systems, pesticides, and fertilizers, other sources of contamination from individual households include: chemicals used in termite control, cleaning products, paint, and automotive products. Because it is difficult to monitor the disposal of these products, public education is critical regarding individual responsibility for clean groundwater. Albemarle County has one Environmental Protection Agency (EPA) Superfund site located at the former Greenwood Chemical Company near Newtown. EPA has removed the contaminated soil and the site and is now developing a plan for treating contaminated groundwater. There is one common denominator for each source of groundwater contamination discussed in this section: Groundwater pollution is difficult and expensive to detect and remove. The most economical and effective groundwater protection strategy is the prevention of contamination. Mapping Groundwater Vulnerability One method of preventing groundwater contamination is to map those areas with increased vulnerability to contamination based on soils, geology, land uses, and other factors. These types of maps can be used when making land use decisions and for site designs to minimize the opportunities for groundwater contamination. 47 One technique to perform this type of mapping is the DRASTIC system, which has been used by the Environmental Protection Agency, Virginia Water Project, and Thomas Jefferson Planning District Commission (TJPDC). TJPDC has produced DRASTIC maps for Louisa and Nelson counties. While DRASTIC is known to have some shortcomings with regard to data availability and data analysis, other similar techniques are available or could be developed. This effort would overlap with the mapping of surficial and bedrock geology and other hydrogeologic features (see section on Hydrogeological and Water Quality Testing). Strategy: Seek an effective way to collect, store and use groundwater contamination source informatior~ The County should work with the Division of Mineral Resources, Thomas Jefferson Planning District Commission, Department of Environmental Quality, and University of Virginia to identify and map existing and potential sources of groundwater pollution. The County's evolving geographic information system should be utilized Management objectives should be developed.

Strategy: Conduct a study of possible shortfailings of current state septic regulations to protect groundwater and any necessary improvements to current design criterit~ Implement additional non-regulatory and/or regulatory measures needed to adequately protect groundwater from septic systems.

GROUNDWATER PROTECT[ON STUDY Water Resources Committee Update The Groundwater Protection Study for Albemarle County was developed by the Department of Planning and Community Development. The Board of Supervisors accepted the report in principle June 13, 1990, and assigned program implementation to the Watershed Management Official, now the Water Resources Manager. In 1993, the Board of Supervisors requested an update on implementation of the study from the Water Resources Committee. The original study contained 20 recommendations for addressing groundwater issues in Albemarle County. Of the 20 original recommendations, the Committee gave highest priority to maintaining a pollution source data base and developing a public education and voluntary action program. Maintaining water quality testing data in a data base was also rated high, but it is dependent on a water quality testing requirement which has not yet been implemented. The Committee's evaluation identified the following high priority actions consistent with the Groundwater Protection Study recommendations: Tackle coordination of groundwater information and data analysis and public outreach on a scale smaller than the whole County. Procedures developed for this pilot area could subsequently be applied to other 48 3. 4. 5. 6. 7. areas of the County, and, ultimately, County-wide. Educate the public and homeowners about responsible stewardship of groundwater resources. Continue coordination by the Water Resources Manager, the Planning Department, and other relevant agencies of groundwater and surface water activities. Continue to develop a quality comprehensive data base of groundwater information, with evolution towards a geographic information system (GIS). Offer voluntary well testing programs. An initial program could be offered as part of the pilot area project. Assemble relevant local, regional, state, and federal agencies for an Albemarle County groundwater summit to improve coordination and facilitate information sharing. Continue activities of the Water Resources Committee to study groundwater issues, oversee a pilot watershed project, and advise the Board of Supervisors on continued implementation of the Groundwater Protection Study' s recommendations. All of these high priority actions are reflected in the strategies listed in this Plan. Strategy: The Groundwater Subcommittee of the Water Resources Committee should continue to study groundwater issues and advise the Board of Supervisors on the continued implementation of the Groundwater' Protection Study recommendations. North Fork/South ForkHardware River Wa~rs~e~,Pi~lot. Gg0gnd~at~g~S~p~dy The Water Resources Committee recommended a pilot groundwater study to develop procedures for data collection and analysis that could later apply to a County-wide program, and to provide information for the update of the Comprehensive Plan. The North Fork/South Fork Watershed w~ se!e~ted because th? ~a~e[sh~d is epfir~ly dependent on groundw~ater for drinking water supplies, and the watershed contains the former Village of North Garden where groundwater availability had been an issue identified in the Comprehensive Plan. The pilOt study identified private water systems that provided representation across natural and cultural variables, such as geology, land use density, and well construction type and age. Niflety private water systems were tested, and a survey administered to the users of the systems. This was done to determine if water quality and quantity results could be related to the variables, and if any spatial patterns emerged. The most widespread water quality problem evident from both the user survey and laboratory results was low pH, or acidic water, which is very common for well water across the Piedmont. Positive total coliform and.nitrate- nitrogen levels in excess of 1 milligram per liter were each present in 24% of raw water (untreated) samples. (Note: the EPA has set a maximum level of 10 mg/L of nitrate for public water supplies. Levels in excess of 1 mg/L are higher than would normally be found in groundwater.) The most important factors influencing positive results were the age and construction of the water system. Older systems, and springs, bored and dug wells (which tend to be shallower than drilled wells) are more susceptible to water quality problems. About 20-25% of well users are knowledgeable about how their water systems work, and are aware of potential contamination and/or low flow problems. The remainder would benefit fromeducation about the..stewardship practices necessary to protect their own water supplies and those of their neighbors and communities. An issue raised by the survey which has the potential to be a serious concern for groundwater users is that 57% of respondents reported having an underground or above ground storage tank for home fuel oil, gasoline, or other materials. Resident testing for hydrocarbons was nearly nonexistent. Almost nothing is known about the extent of damage these tanks, particularly underground tanks, may be causing to well water. 49 Recommendations developed from the pilot study are: 1. Conduct regional hydrogeological studies for areas where extensive water supply development is anticipated or possible, and no public utilities are foreseeable. A regional study could include geologic mapping, additional resident surveys, and pump testing of selected wells. 2. Prescribe policy guidelines for on-site hydrogeologic testing when needed to verify a suitable water supply for development proposals. 3. Pursue voluntary well testing programs as an educational tool for groundwater users, and to facilitate the collection of data. Support the Virginia Cooperative Extension Household Water Quality Testing program planned for the spring/summer of 1995.' Develop educational programs for groundwater users that address specific information needs highlighted by this study. Seek an effective way to ~°llect, store and use groundwater data. Coordinate With the Health Department. Utilize the County's evolving geographic information system (GIS). Address County staff resources needed to implement a groundwater program. All of these recommendations are reflected in the strategies listed in this Plan. Cooperative Extension County-Wide Well Testing Program During the summer of 1995, a voluntary program of household water quality education, which included water sampling, testing, and diagnosis was conducted, sponsored by Virginia Cooperative Extension Service. Water' samples from 497 households were analyzed. These analyses identified corrosivity and bacteria as the major water · quality problems in the County~ After completion of the general water testing program, water supplies from 19 households were resampled for the testing of 25 pesticides and other chemical Compounds. None of the samples had contaminants exceeding EPA' Health Advisory or Maximum Contaminant Levels. Following completion of the program, survey forms were mailed to the 497 participants. Two hundred eighty-four participants returned thc forms, indicating reasons for participating in the survey and what measures they planned to take, or had already taken, to correct water quality problems identified in the testing program. Forty-nine percent of the households that reported having at least one water quality problem had taken, or planned to take, some measure to improve the quality of their water supply, including obtaining water trea~ent equipment, shock chlorination, additional water testing, and improving the physical condition of the water source;among other measures. Groundwater Data Base The development ora groundwater data base system was initiated in 1990 by the Department of Planning and Community Development which utilized information from well completion reports. During the summer of 1996, the Division of Mineral Resources took an active interest in using Albemarle as a case example for developing a usable and useful groundwater data b'ase using GIS. The Health Department currently collects well completion reports and sends copies to the County. These reports are now being forwarded to the Department of Mineral Resources for its data base. Another soume of information for the data base is the w. ell testing program. Ultimate uses of the data base include tracking the location of wells, relating well yields t° bedrock geology, and identifying areas where regional aquifers may be dropping due to groundwater pumping. The data base would be useful not only to the County for planning purposes, but to well drillers, developers, citizens, and other government agencies. Strategy: Seek an effective way to collect, store and use groundwater dattr Coordinate with the Health Department and Division of Mineral Resources to develop a useable and continuoUsly_maintained groundwater data base. Utilize the County's evolving geographic information system (GIS). Management 50 objectives that outline how, for what purpose, and by whom the data base will be used should be developed. Strategy: Provide cost-share and staff assistance to Division of Mineral Resources to complete the Albemarle County pilot groundwater data base. Strategy: Consider groundwater resource data in the review of rezoning and special use permit applications. Groundwater resource studies are to be done on a periodic basis to update data. I-Iydrogeological and Water Quality Testing Hydrogeological testing may be implemented on two scales for different purposes. On a County-wide or regional scale, studies can be initiated by the County to generate data for planning purposes. On a smaller scale, it would be beneficial to require a property owner to provide site specific hydrogeologic testing to determine the adequacy of groundwater to serve a proposed development. Hydrogeological testing is intended to protect and preserve groundwater quantity and quality through: 1) careful subdivision design; 2) better assurance of adequate water supply for future residents; 3) assessment of the effects of anticipated withdrawals on neighbors; and 4) planning generally for the location of development in relation to recharge areas and other factors. County-Wide or Regional Scale Studies: The Groundwater Protection Study makes several recommendations pertaining to hydrogeologic studies and mapping projects. While these types of projects are expensive, they can be focused to best meet specific County needs. Planning for growth in areas not accessible by public water and sewer involves attempting to understand hydrogeologic constraints for both water supply and quality. A regional study conducted by the County could include detailed geologic mapping, resident surveys, and pump testing of selected wells. The Division of Mi.n~r~!~.R~sources is currently updating the geology for specific Albemarle County USGS quadrangle maps. Studies could als9 inc!gde regional recharge/discharge analysis, identification of recharge areas, and regional flow paths. A prioritized list of watersheds should be developed based on development potential, hydrogeological setting, and other factors. Studies and mapping should be designed in a manner that provides guidance to the County's decision makers about the capabilities and limitations of groundwater resources to support certain types and scale of rural development. Site or Development Scale Testing: Hydrogeologic testing can also be applied to specific development proposals. However, the County does not have any policy guidelines detailing what type of information is required, or how it would be used to make decisions about specific development proposals. Also, the County needs to confirm that existing enabling legislation provides authority to require such testing. Consideration should be given to requiring hydrogeological testing prior to subdivision approval in the Rural Area to ens~e~ that !~e..~t?~Sgpply quantity and quality is adequate to serve the eventual inhabitants ofth~ area,_ Also, consideration should be given to requiring hydrogeological testing for site plans in the Rural Area. Key components of this hydrogeological testing policy should include the following information: 1) A clear understanding of when hydrogeological information would be required (e.g., size of development, location factors, etc.) 51 2) 3) Clarification of how hydrogeological information would be used to make decisions about · individual development projects. This is an important factor since County approval Could be construed by a potential homeowner as a guarantee that adequate water exists. On the other hand, ifhydrogeological information is used to reject a development proposal, the technical and legal basis of this rejection must be defensible and equitable. Clear guidance of what type and detail of information is required, and approved method for collecting the data. Albemarle County has received enabling legislatiori, along with several other Virginia counties, to require reasonable testing of water quality prior to issuance of a building permit. This allows the assessment of poor water quality before a dwelling is constructed. It is also a method to collect water quality data. The Health Department does not require water quality testing of private wells, with the exception of bacteriological (coliform) testing. Strategy: Work with the Division of Mineral Resources to conduct additional mapping in Albemarle County on recharge/discharge, lineaments, surflcial and bedrock geology, and regional groundwater flow. Provide local cost-share funds to perform this mapping. Strategy: Continue to gather information on groundwater by watershed areas using the Pilot Groundwater Study as a prototype. Produce a prioritized list of watersheds using criteria developed by the Groundwater Subcommittee of the Water Resources Committee. Strategy: The Groundwater Subcommittee should investigate a requirement for hydrogeological testing to verify suitable groundwater quantity and quality in the Rural Arec~ If appropriate, they.should develop a draft hydrogeological testing policy and ordinance language for consideration by the Board of Supervisors. Strategy: The Groundwater Subcommittee should investigate a requirement for a water quality testing requirement for private wells prior to issuance of a building permi~ If appropriate, they should develop a draft ordinance language for consideration by the Boardof Supervisors. Groundwater Education The Pilot Study and County-wide Well Testing program provided some clarification of the educational messages that are important for County groundwater users. These principles include: periodic water testing, proper septic system maintenance, knowledgeable yard and garden care, best management practices for pasture and other agricultural uses, water conservation, proper household hazardous materials use and disposal (including automotive products), and fuel oil tank monitoring and maintenance. In addition, private, individual system owners and users should strive to become informed about their systems (e.g., age and depth, and proper treatment for specific water quality problems). Forums should be identified, in collaboration with other agencies, for the effective dissemination of educational materials. Strategy: In conjunction with other educational efforts and organizations, the County should disseminate relevant information to groundwater users about stewardship principles, including specific information needs identified by the Pilot Study and Well Testing Progratt~ 52 WELLHEAD PROTECT3ON This section has been adapted from Wellhead Protection, A Handbook for Local Governments in Virginia, and Wellhead Protection: Case Studies of Six Local Governments in Virginia, Virginia Ground Water Steering Committee, Fall, 1993. Wellhead protection is the term applied by EPA and others to describe a process for: (1) Assessing potential threats to groundwater, (2) Managing land uses and activities in the area near public water supply wells, and (3) Planning to prevent problems before they arise. A wellhead protection area is a specified area in the vicinity of a public water supply well designated for special protection to prevent pollution of the groundwater from nearby surface and sub-surface activities. The size and shape of the protection area is a function of factors such as the hydrogeology in the vicinity of the well, its daily withdrawal rate, land use activities existing or likely in the area, and assessment of options if the well were to become polluted. The area could range from a few acres to several square miles or more. Special protection measures which could be applied to a wellhead protection area include zoning limitations on the types of land uses allowed, performance standards to contain and manage potential pollutants, contingency plans for hazardous spills, and coordination among local, state, and federal governments and property owners. Objectives for wellhead protection should be defined, to address issues such as: 1) Protection of groundwater resources from contamination; 2) Management of land-use activities that store, handle or produce regulated substances; 3) Minimizing the expenditure of public and Private monies for the establishment or extension of the current public system; and 4) Planning for emergency response in the case of hazardous materials spills, flooding, and other emergencies. Strategy: The Groundwater Subcommittee of the }Fater Resources Committee should develop a wellhead protection plan and implementation program for the County (Include as an Action Agenda Item). Strategy: As a first step in a wellhead protection program, map all current public water supplies that utilize wells and springs, including the latitude and longitude of all source supplies. Produce this map for emergency response personnel, the Comprehensive Plan, and other groundwater planning applications. GROUNDWATER STANDARDS The following GENERAL STANDARDS should be applied to protect groundwater: Construct wells and septic systems prior to construction of a new home or building. Locate wells as far as possible and uphill from potential sources of contamination, such as septic systems, fuel storage tanks, buildings treated for termite control, animal feedlots, and roads subject to de-icing compounds. Suggested Minimum Separation Distances From Wells Septic system drainfield 100 ft. Septic tank 50 ft: Termite-treated dwelling 100 ft. 53 Barnyard or feedlot 50 fi. (downhill from well) Source: State Health Department Locate wells on the high ground away from areas that flood. Surface drainage should be directed away from the well site. In addition, the following are important guidelines that promote conservation and maintain groundwater quality for individual households and the County's general health and safety. These should b,e exercised by the general citizenry and included in public information brochures: · Test wells for bacteria and nitrates once a year and for chemicals every three years. ° Maintain and pump septic systems regularly, every three to five years. · Maintain grass cover over a septic drainfield. Trees or shrubs should not'be planted where roots may damage the lines. Avoid garbage disposal units unless the septic system has been designed for the extra solids load. Avoid disposal of toxic and hazardous chemicals -- such as gasoline, pesticides, paints, solvents, and photographic chemicals -- in a septic system. They may harm the septic action, damage the soil absorption system, and contaminate the groundwater. Household hazardous materials should be collected and taken to the Rivanna Solid Waste Authority household hazardous waste collection site (currently at the Ivy Landfill). Practice water conservation methods, such as low-flow faucets, showerheads, and conservatiofi equipment. Use alternate water sources for irrigation of yards and gardens. Apply pesticides and fertilizers, .when necessary, in as limited amounts as necessary to complete the task. Empty containers should be disposed of properly Chemicals should never be used, mixed, or stored near a well. TO reduce the use of fertilizers and pesticides, use ground cover or mulch in lieu of a maintenance-intensive lawn. Dispose of hazardous and toxic wastes from households and businesses properly. Motor oil and paint thinner should be recycled. Underground and above ground storage tanks for home fuel oil and other hazardous materials should be monitored annually for fuel level and checked thorougly by a qualified professional if a leak is suspected. Old underground tanks should be replaced with above ground tanks with proper spill containment. 54 Biological Resources and Biodiversity "... it is difficult to believe that it lies with [man] so to remodel the work of nature as it would be remodeled, by a destruction not only of individuals, but of entire species; and not only of a few species, but of every ' ' i n" species, with the very few exceptions which he m~ght spare for h~s own accommodat o . - James Madison, excerpt from speech to the Albemarle Agricultural Society of Albemarle, Charlottesville, Virginia, May 12, 1818 GOAL;. Recognize the importance of protecting biological diversity in both the Rural Area and the Development Areas for the ecological, aesthetic, ethical, and economic benefits to the community. Introduction Biodiversity is short for biological diversity. It describes the variety of living organisms of all kinds - animals, plants, fungi and microorganisms - that inhabit a particular area or ecosystem. Protecting and understanding biodiversity is a task that requires a long-term, large-scale view. Most commonly, biodiversity is measured by the number of species present in an ecosystem. However, biodiversity also includes: genetic diversity within those species in the ecosystem, and the diversity of different ecosystems across landscapes. These three levels (species diversity, genetic diversity, ecosystem diversity) interact in an extremely complex manner, and these interactions provide the life support of all species. SPECIES DIVERSITY Species diversity can be described as the variety of organisms that live in a particular area or habitat and that may be linked as biotic communities, usually through food webs. Perhaps because the living world is most widely considered in terms of species by the public, the concept of biodiversity is commonly interpreted to mean species diversity or "species richness," which may be described at various levels, from local to regional. GENETIC DIVERSITY Genetic diversity is the heritable variation within and among populations of organisms. AS a plant, animal, fungus, or microorganism population becomes smaller due to human, impact, habitat destruction, or natural change, genetic variability tends to be lost by chance. The loss of genetic variability usually affects the viability and survival of a species by reducing its ability to reproduce or to deal effectively with environmental factors such as disease, weather, predation, etc. ECOSYSTEM DIVERSITY Ecosystem diversity describes the variety of different natural systems found in a region and is delimited and characterized by the boundaries and interactions among biological communities and the physical landscapes that support them. The interactions among animals, plants, and micro-organisms with the physical environment produce a wide variety of ecosystems that may be described at a range of temporal and spatial scales. 55 Importance of Biodiversity Why should we care about biodiversity? 1) Biodiversity is essential to human life. Human life depends on the products of living organisms, world- wide. Whether these animals, plants, or microorganisms are wild or domesticated,they provide food, medicine and industrial products essential to mankind. Furthermore, these products form the backbone oft he world's economy. That is, fisheries, forestry, agriculture, and o.ther industries depend on animal and plants and therefore rely directly on a diversity of biologiCal resources. Soil bacteria are essential for productive farmlands. Other bacteria provide crUcial vitamins and enzymes. Biodiversity of species, landscapes, and ecosystems also provides for ecological services, such as: retention of clean water, production of oxygen, consumption of carbon dioxide, resistance to parasites and disease organisms, control of agricultural pests, pollination, and critical recycling of inorganic nutrients upon which all natural productivity depends. 2) BiodiverSity preserves the aesthetic and economic value. Many people come to Albemarle County because of its great natural beauty, views of the Blue Ridge, wooded hillsides and pastures, and scenic creeks and rivers. Natural, diverse landscapes and the proximity to wildlife provide enrichment to our citizens that is unique in its impact and that is irrePlaceable. The natural environment of Albemarle County complements its historic resources and together these features drive the tourism industry that is so vital to our economy. Protection of biodiversity is integral to maintenance of Albemarle's overall environment. 3) Humanity has an ethical responsibility to care for other forms of life on earth. We as humans have a responsibility to care for other species on Earth, whether or not those species have direct economic use. Rather than simply using the Earth's resources for present purposes, human beings have a responsibility to care for the Earth's future. Biodiversity is integral to the functions of ecosystems, sustains animal and plant species of direct economic value t° humans, and minimizes the effects of both natural and human-caused environmental disturbance. Albemarle County Trends Albemarle County lies within the Southern Appalachian - Eastern Deciduous Forest, the most species-diverse portion of temperate North America. Over the decades, forest clearing and regrowth, burning, development and other activities and events have affected the Albemarle County landscape. In addition, and especially since 1950, the human population of Albemarle Co. unty and Charlottesville has grown rapidly. Perhaps the greatest threat to our natural environment is the increasing demand for, and thus, increasing economic value of, land. Residential, commercial and industrial development continue to expand onto our rich and diverse landscape, causing fragmentation of habitats and conversion of land in the Rural Area to more intensive uses. In addition, the use and management of properties within Development Areas have similar impacts on the habitats and biological resoumes of the County. As a result, populations of some species have disappeared and others are undergoing major reductions. Consequently, we must anticipate erosion over time of our ecosystems and the services they provide us and attempt to take corrective measures. For example, in Albemarle County today, only a few patches of old growth forest still exist. Tree varieties characteristic of mature forests have suffered reductions, and some have been lost through disease (such as the American Chestnut). Various native species have been lost or diminished through habitat loss (neotropical migratory birds), and a number of exotics and non-native species have been introduced (such as the Paradise Tree, Ailanthus); such exotics present particularly insidious problems, as they often become unwelcome pests, which 56 outcompete and replace natives. Prominent animal loses or substantial declines in species formerly native to this area include the passenger pigeon, wolf, puma, and bison. Recent bird declines include the loggerhead shrike, wood thrush, whippoorwill, and Bewick's wren. In turn, species accustomed to open fields or meadows or edge areas such as the robin, cowbird, deer, and ground hog have increased in numbers. Losses of larger predators such as wolves, mountain lions, · bobcats and coyotes have' led to increases in smaller predators, such as raccoons, skunks and opossums; these smaller, opportunistic predators have been seriously augmented by feral or free-ranging domesticated animals, mostly cats and dogs, both of which are persistent and efficient predators. Fresh waters have perhaps suffered the most through clearing of land, sedimentation, and pollution, As a result, fishes have declined drastically, and Albemarle's freshwater mussels, such as the green floater and the James spinymussel, are designated as endangered. Although the preservation of one particular endangered species may not seem at first glance to be critical, it is important to consider that this is one indicator that the ecosystem is becoming ecologically unsustainable. That is, the presence of an endangered species is often indicative of a decline in the general health of its habitat. 57 Natural Heritage Resources of Albemarle County, Virginia - Updated June, 1998 SCIENTIFIC NAME ** COMMUNITIES ** INVERTEBRATES FUSCONAIA MA $ONI LASMIGONA SUBVIRIDIS PLEUROBEMA COLLINA PYRGUS WYANDOT SPEYERIA IDALIA STYGOBROMUS SPINOSUS ** REPTILES "PITUOPHIS MELANOLEUCUS ** VASCULAR PLANTS ALNUS INCANA SSP RUGOSA BETULA PAPYRIFERA CALYCANTHUS FLoRIDus VAR GLAUCUS CORALLORHIZA MACULATA VAR OCCIDENTALIS CORNUS CANADENSIS ELYMUS CANADENSIS PHLOX BUCKLEYI PRUNUS NIGRA RORIPPA SESSILIFLORA SIDA HERMAPHRODITA SOLIDAGO RANDII COMMON NAME GLOBAL STATE FEDERAL STATE RANK RANK STATUS STATUS EASTERN HEMLOCK FOREST CHESTNUT OAK FOREST LOW ELEVATION BASIC OUTCROP BARREN ATLANTIC PIGTOE G2 S2 GREEN FLOATER G3 S2 JAMES SPINYMUSSEL G1 S1 APPALACHIAN GRIZZLED G2 S2 SKIPPER REGAL FRITILLARY G3 S1 BLUE RIDGE MOUNTAIN G2G3 S2S3 AMPHIPOD PINE SNAKE SPECKLED ALDER PAPER BIRCH SMOOTH SWEET-SHRUB WESTERN SPOTFED CORALROOT BUNCHBERRY NODDING WILD-RYE SWORD-LEAVED PHLOX CANADA PLUM STALKLESS YELLOWCRESS VIRGINIA MALLOW RAND'S GOLDENROD G5 SU G5T5 S2 G5 S2 G5T5 S 1 ?

Y Y Y :c~,~ Y Y Y N No Date Y No Date N Y N Y Y N .Y N N Y Y Definitions of Abbreviations Used on Natural Heritage Resource Lists State Rank The following ranks are used by the Virginia Department of Conservation and Recreation to set protection priorities for natural heritage resources. Natural Heritage Resources, or "NHR's," are rare plant and animal species, rare and exemplary natural communities, and significant geologic features. The criterion for ranking NI-IR's is the number of populations or occurrences, i.e. the number of known distinct localities; the number of individuals in existence at each locality or, if a highly mobile organism (e.g., sea turtles, many birds, and butterflies), the total number of individuals; the quality of the occurrences, the number of protected occurrences; and threats. · SI - Extremely rare; usually 5 or fewer populations or occurrences in the state; or may be a few remaining individuals; often especially vulnerable to extirpation. oS2 - Very rare; usually between 5 and 20 populations or occurrences; or with many individuals in fewer occurrences; often susceptible to becoming extirpated. oS3 - Rare to Uncommon; usually between 20 and 100 populations or occurrences;may have fewer Occurrences, but with a large number of individuals in some populations; may be susceptible to large-scale disturbances. oS4 - Common; usually > 100 populations or occurrences, but may be fewer with many large populations; may be restricted to only a portion of the state; usually not susceptible to immediate threats. oS5 - Very common; demonstrably secure Under present conditions. ,SA - Accidental in the state. oS#B - Breeding status of an organism within the state. oSH - Historically known from the state, but not verified for an extended period, usually > 15 years; this rank is used primarily when inventory has been attempted recently. oS#N - Non-breeding status within the state. Usually applied to winter resident species. oSU - Status uncertain, often because of low search effort or cryptic nature of the element. oSX - Apparently extirpated from the state. 00 °SZ - Long distance migrant whose occurrences during migration are too irregular, transitory and/or dispersed to be reliably identified, mapped and protected. Global Rank Global ranks are similar, but refer to a species' rarity throughout its total range. Global ranks are denoted with a "G" followed by a character. Note that GA and GN are not used and GX means apparently eXtinct. A "Q" in a rank indicates that a taxonomic question concerning that species exists. Ranks for subspecies are denoted with a "T". The global and state ranks combined (e.g. G2/S1) give an instant grasp of a species' known rarity. These ranks should not be interpreted as legal designations. Federal Status The Division of Natural Heritage uses the standard abbreviations for Federal endangerment developed by the U.S, Fish and Wildlife Service, Division of Endangered Species and Habitat Conservation. LE - Listed EndangeredLT -Listed ThreatenedPE - Proposed EndangeredPT - Proposed ThreatenedC - Candidate (formerly C 1 - Candidate Category 1)E(S/A) - treat as endangered because of similarity of appearanceT(S/A) - treat as threatened because of similarity of appearance. State Status The DiVision of Natural Heritage uses similar abbreviations for State endangerment. LE - Listed EndangeredPE - Proposed EndangeredSC - Special Concern - animals that merit special concern according to VDGIF (not a regulatory category) LT - Listed ThreatenedPT - Proposed ThreatenedC - Candidate. 59 Habitat Fragmentation The major causes, world-wide, for the reduction of species is destruction and fragmentation of habitat. Other causes include introduction of exotic and non-nativespecies and over-exploitation. Here, we are concerned with fragmentation, which is of particular concern to Albemarle. Fragmentation is the carving-up of habitats into ever-smaller areas, with the accompanying lack of connections, called "corridors," among the fragments. Whereas, fragmentation is known to be biologically and ecologically destructive to biodiversity, the prediction of effects With a high degree of certainty can be problematical, requiring expert assessment. BENEFrI'S OF UNBROKEN HAB~ATS Conventional wisdom dictates that the more contiguOus a habitat or ecosystem, the greater number and variety of birds, animals, and plants it will sUpport. Also, it is often assumed that unbroken habitats provide continuous protective pathways for the safe movement or migrations of animals or expansions of plants. These statements, however, can be misleading, as they apply mainly to species that are at least somewhat obligate to the habitat or ecosystem in question. Whereas fragmentation can be devastating to those species, it can also actually increase the total number of species. But the downside to that apparent benefit is that those latter species are likely to be what ecologists call "weedy" or "opportunistic," and hence undesirable (for example the cowbird, which is a nest parasite on warblers and other birds and is a major factor in their decline.) Forests, in particular, are an important asset for Albemarle. Many birds, mammals, reptiles, amphibians, and aquatic species depend upon this dominant habitat for their survival. Additionally, the protection afforded by the forest's leafy canopy helps improve air quality and modulates microclimate. Forested areas also protect and maintain the purity of groundwater and stream and river water. Forests serve as filters to trap sediment and absorb pollutants from overland runoff. Loss of topsoil and silt into surface waters can smother the gravel bottoms that are breeding habitats of most of our stream fishes and the aquatic insect larvae that are the food for these fishes. Forests along rivers and streams help make waterways livable for many species. For example, many shrubs, grasses, and vines grow well in moist and fertile soil; of large unbroken forested areas, but may not do well elsewhere. Plant material falling into the water also provides a food source. Shade from the tree canopy helps maintain a low water temperature, and tree roots help stabilize the bank and provide shelter. Finally, forests contribute to Albemarle's natural beauty, complement the cultural resources of the area and enhance the County as a desirable place to live, recreate, and visit. EFFECT OF HABITAT FRAGIVlENTATION ON SPECIES The decline of many plant and animal species in Albemarle can be attributed to large scale tree clearing, or by development activities such as woodland subdivisions, power lines, and roads. The habitat fragments that these activities produce differ from the original habitat in two important ways: 1) the center of a fragmented area is closer to the fragment's edge; and 2) the amount of edge relative to the amount of interior habitat is dramatically increased. Because of fragmentation, the center of the habitat is closer to the edge,which exposes the species within to increased predation and competition. Furthermore, the habitat's edge represents a dynamic environment into 60 which many other species can invade Thus, fragmentation not only increases the number of predators within the edge, but some of these predators compete for the same food supply as species within the habitat. For instance, predatory animals may decimate insect and amphibian populations in edge areas. Forest fragmentation also reduces the ability of a species to move freely across a habitat to forage, to find mates,or to disperse to neighboring habitats. The resulting isolation and reduced population numbers may, in mm, lead to loss of genetic variability, which reduces a species' viabilty and its ability to to deal with environmental fluctuations, disease and predation. Also, many plant species that rely on animals to transfer seeds are also affected, which can have widespread ecosystem consequences. The interactive sequence of events described in the preceding paragraph is termed an "environmental cascade," which does not end at the level of the habitat. Some regional effects of forest clearing and fragmentation, for example, include changes in reflected solar radiation, air and soil temperature, wind, and incidence of fire. Plant cover offers shade and protection of soils, particularly in forest communities, which maintain relatively cool, moist, and shaded environments during spring and summer days, and trap heat during the night. Effects of large-scale clearing and development are currently having nation-wide to global ramifications, with marked changes in species diversity and ecosystem services. Habitat fragmentation is currently being addressed, in part, in Albemarle through land use policies and voluntary measues to protect foreslry and open space in general, such as Rural Areas zoning and Agricultural/ Forestal Districts. The Agricultural/Forestal Industries Support Committee stated, "Continued forest fragmentation is probably the biggest threat to the future viability of the forest industry in Albemarle County....Forest sizes below 40 acres are difficult to manage economically." The Mountain Protection Committee concurred, "The principle threat to the County's mountain forests and farms has now become fragmentation and conversion to residential land use." This Comprehensive Plan continues to support and promote forestry and agriculture as priority land uses in the Rural Area. However, certain areas of the County may require additional protection to insure that biological diversity is maintained. This may be accomplished through an implementation program that stresses education and voluntary actions. Implementation of a Biodiversity Program OBJECTIVE: Increase the community's awareness of the importance of biodiversity to encourage protection of biological resources. BUILDING BIODIVERSITY AWARENESS. We should value our natural surroundings as ecosystems that provide essential services to humans. Destruction and fragmentation of habitat is usually not deliberate, but results from other activities such as building a new home. Therefore, increasing the public's awareness of biodiversity, and how the public's actions affect our ecosystems, is key to implementing a successful program. Other than the Shenandoah National park and other publicly owned parks and school sites, almost all of the land in Albemarle County is owned privately. Thus a motivated, informed citizenry can greatly effect changes in the health of ecosystems through increased awareness of the importance of biodiversity. Strategy: Develop and disseminate educational and technical material for the purposes of informing the general public, developers, and private land owners, including residents of urban Development Areas, on the value of biodiversity and volunteer techniques that can be used to protect biological resources located on their ianc~ 61 Recommendations: Develop material and conduct educational sessions to provide information to the public on the importance of biological resources to our County and the positive effect these resources have on maintaining our high quality of life. Develop illustrations and other materials that demonstrate biological resource protection efforts that developers can consider utilizing when developing a site. Educate individual land owners through pamphlets and other methods on immediate volunteer efforts they can do to protect biological resources on their property. The County could provide information at meetings or in leaflets to explain the importance of biodiversity, and to inform landowners how to protect biological resources on their land. For example to: Seek to reduce habitat fragmentation by maintaining large contiguous patches of woods, meadows, wetlands, and streams. Plan to allow old growth forest areas to develop. Resist the urge to remove all dead timber. Minimize lawn areas; plant and maintain meadows instead. Avoid exotic and non-native plants; use native shrubs and trees that produce berries. Sow seeds of native wild flowers. Keep livestock out of the streams. Put up nesting boxes. Minimize the use of pesticides. Preserve fencerows in a natural state as habitat for wildlife. Do not allow domesticated pets to roam free, especially at night. Learn to recognize and suppress invasive non-native plant species such as garlic mustard (21lliaria petiolata) and mile-a-minute (Polygonum perfoliatum). OBJECTIVE: Through a Biological Resources Inventory, develop ~ systematic knowledge of the types and distributions of biological resources in Albemarle County, and develop an understanding of the requirements of our ecosystems. CONDUCTING a BIOLOGICAL RESOURCES INVENTORY The County needs to develop systematic knowledge of the type and distribution of biological resources in the area. The Open Space and Critical Resources Plan, adopted in 1992, recommended completion of a critical resource inventory to plan for open space and significant resource protection in the Rural Area. Areas containing significant biological resources may be identified by a number of criteria, such as habitats of specific plant or animal types, catchment or filter areas, riparian areas, mountain areas, unbroken patches of forests, and patches of land that have been relatively undisturbed by humans. Sources for the preliminary identification of areas of concern include: aerial photos, satellite images, multispectral imagery, and digitized spatial data bases. Data bases available for Albemarle County include surface water distribution, elevations, soil types, vegetative cover types, and land classified by usage type. These databases can be used to construct layers in a Geographic Information Sysytem (GIS), to be incorporated into the existing County GIS system. 62 Other sources include the citizens of the County. are avid, experienced naturalists and could provide much information on the distribution of plant and animal species and communities. Local foresters also have a great deal of firsthand knowledge of the distributions of forests of different types. A biodiversity committee composed of knowledgeable and interested citizens is essential for the coordination of the Biological Resources Inventory. Strategy: Establish an advisory committee to assist the County in overseeing the development of a Biological Resources Inventory and the integration of such an inventory into the planning process. APPOINTING A BIODIVERSITY COMMITTEE A Biodiversity Committee should be appointed to oversee the development of a Biological Resources Inventory and its integration into the planning process. The committee should be composed of interested citizens representing environmental, agricultural, forestry, and business interests. Members may include local foresters and farmers, conservation biologists, skilled amateur naturalists, a representative of the Shenandoah National Park, land owners, developers and other concerned citizens. The Biodiversity Committee should be a continuing committee. It should assist the staff in developing an action plan for protecting biological resources, and should periodically report to the Board of Supervisors on the state of our biological resources. The responsibilities of this committee would be to: 1) develop public educational materials on biodiversity; 2) develop methods and oversee a Biological Resources Inventory to be conducted for the County; 3) solicit regional cooperation among nearby counties in collaborating on a regional inventory; 4) determine criteria for identifying the types of biological resources to be inventoried; 5) assess prospects for donations to the Inventory of time, expertise or other resources from the community, including the University of Virginia; 6) evaluate methods of conducting the Inventory; 7) recommend one or more approaches for conduct of the inventory to the Board of Supervisors, with estimates of costs; 8) assist staff in developing an action plan (discussed below) that specifies detailed steps for achieving protection of biodiversity as outlined in the Comprehensive Plan; and 9) provide periodic reports to the Board of Supervisors on the state of biodiversity in the County. OBJECTIVE: Conserve. ecological communities to ensure their continued genetic diversity, and protect ecosystems that provide essential sevices to humans. Strategy: Staff should develop an action plan, with assistance from the Biodiversity Committee, and through a public participation process, to protect significant areas of biological resources. 63 DEVELOPING AND IMPLEMENTING AN ACTION PLAN FOR ACHIEVING BIODIVERSITY Following the completion 'of the Biological Resources Inventory, staff should develop an action plan in conjunction with the biodiversity committee. This plan should provide specific details for achieving the protection ofbiodiversity and biological resources as outlined in the Comprehensive Plan. Actions to be addressed in the action plan at a minimum should include: How the information obtained from the biological inventory will be incorporated into the land- use decision making process. Procedures to protect biological resources may be similar to the implementation procedures for significant resources outlined in the Open Space Plan. Establishing educational programs. Procedures for the establishment/maintenance of a biological resource data base. Voluntary measures that could possibly be utilized by the County such as use-value assessments of rural lands, agricultural/forestal districts, conservation eagements, etc. to protect areas identified as significant biological resources. Whether there is a need for hiring a County staffmember with expertise in conservation biology, and/or training existing County staff in principles of conservation biology.

"The importance of agriculture and forestry is not limited to the production value of these industries. Each farm or forestry operation provides employment and helps support other related businesses in the community. In addition, the income derived by the landowner encourages the landowner to keep the land resource intact. It is the land resource which provides the true value of agriculture and forestry to this community, with related benefits like open space for cleaner air, watershed protection and wildlife habitat; scenic rural and historic landscapes which encourage tourism; and quality of life for all residents. Maintaining agriculture and forestry also enables the County to grow at a measured and deliberate pace, and to better plan for seryices." - The Agricultural and Forestal Industries Support Committee, Report to the Board of Supervisors, February, 1994. Introduction Albemarle County's agricultural lands and forests are among its most visible and treasured resources. "Agricultural and forestry resources" is a defining element for the Rural Area in the Growth Management goal. The Growth Management goal directs development into designated Development Areas, and conserves the balance of the County for Rural Area resource protection. Protection of agricultural and forestry resources is given highest priority in the Growth Management goal because agricultural and forestry uses are the desired primary land use in the Rural Area. Thissection describes the importance of Albemarle County's agricultural and forestry resources, and the reasons for providing protection. It describes the extent of agricultural and forestry resources in the County, and the significance of soils. It outlines the types of protection measures currently in place, both regulatory and voluntary. This section also notes the relationship of agricultural and forestry resource protection to other policies of this Comprehensive Plan: the Rural Area policy and the biodiversity goal. Chapter Four, the Rural Area, describes in more detail the agricultural and forestry uses which depend upon the preservation of agricultural and forestry resources. It also contains additional strategies for the protection of the Rural Area, including agricultural lands and forests. Benefits of Protecting Agricultural and Forestry Resources Protecting agricultural lands and forests provides a resource base for agricultural and forestry land uses. In the Rural Area, agricultural and forestry uses are the preferred land use, rather than residential uses. Agricultural and forestry uses play a long-standing role in the economy, environment and heritage of the County. Agriculture and forestry are major contributors to the economy through market sales, employment, and the generation of support activities. Agricultural and forestry uses are further described in Chapter Four, The Rural Area. In addition to providing a resource base for agricultural and forestry uses, protection of agricultural and forestry resources provides related benefits. Agricultural lands and forests provide the rural character and scenic quality which distinguish this County by conserving the natural and historic landscape and open space. Protecting agricultural lands and forests provides quality of.life benefits for residents and visitors, and encourages tourism. Agricultural lands and forests contribute to the natural environment. Forest watersheds are generally a good source of high quality water due to low sediment yields. Undisturbed forest areas protect critical slopes, reduce surface runoff, and protect air quality. Both agricultural and forestry areas provide wildlife habitat. Finally, agricultural lands and forests provide a fiscal benefit to the County because they provide the basis for economic activities related to agriculture, forestry and tourism, and yet consume so little in County services. 65 'Extent of Agricultural and Forestry Resources The extent of agricultural and forestry resources in Albemarle County can be measured in several ways. Approximately 443,000 acres, or 95% of the total County acreage of 465,040 acres is designated Rural Area in the Comprehensive Plan. In 1997, Albemarle County had 313,491 acres (67.4% of the total County acreage) enrolled in the Use Value Assessment (Land Use Taxation) program. Approximately 308,432 acres (69.7% of the Rural Area acreage) 'were enrolled in the Rural Area. See Table --. The four categories of Use Value Assessment are agriculture, horticulture, forestry, and open space. Table -- shows the acreage in each category by year. In 1997 there were 103, 803 acres enrolled in agriculture; 2,416 acres enrolled in horticulture; 207,138 acres enrolled in forestry; and 134 acres enrolled in open space. Some, but not all, of the remaining acreage not enrolled in the program may also be considered agricultural or forestry lands. This would include land held under conservation easements (which automatically qualify for the same reduced tax rate as land use tax) and other unsubdivided lands. In September, 1998, Albemarle County had 57,550 acres (12.4% of the total County acreage) in 22 districts 'enrolled in the Agricultural and Forestal District program. See Map --. Most of this land is currently enrolled in the Use Value Assessment program. Albemarle County currently has approximately 19,696 acres (4.2% of the total County acreage) held under permanent conservation easements. These properties are probably not enrolled in the Use Value Taxation program but are most likely very suitable for either agriculture or forestry or both. The U.S. Census of Agriculture is published every five years. It defines a farm as "any place from which $1,000 or more of agricultural products were sold, or normally would have been sold during the census year." Table -- shows the Number of Farms, Land (acreage) in Farms, Average Size of Farms and Percent of County in Farms for the Census years 1974-1992. In the most recent year published, 1992, there were 188,567 acres in farms (40% of the County acreage). This represents a decrease of 24, 831 acres since 1974, or 5% of the COUnty acreage. The number of farms in 1992 was 757 farms, compared to a peak of 830 farms in 1982, and a lowpoint of 722 farms in 1987. The size of farms in 1992 was 249 acres, compared to a peak of 285 acres in 1974. In 1992, Albemarle's farms were still 25% larger-than the state average. The USDA Forest Service classified 278,205 acres or 59.8% of the total County acreage as timberland (capable of producing twenty cubic feet of industrial wood per acre per year). This represents an increase of 2,576 acres since 1986. Table --. Most of the timberland is of the oak-hickory group (69%), loblolly-shortleafpine (16%), and oak-pine (14%). Table --. Agricultural and Forestry Soils Probably the most imortant indicator of agricultural and forestry resources is the soil type. Soils are classified according to their suitability for most kinds of field crops. Capability classes are designated by Roman numerals I through VIII, which indicate progressively greater limitations for cultivation. Only Classes I through III are suitable for cultivation. However, Classes IV and VI are suitable for pasture and hay crops which are important crops in Albemarle. Table --. In order to encourage the preservation of important farmlands, Section 3.1-18.5 of the Code of Virginia places the responsibility upon each locality to designate the important farmlands within its jurisdiction. The Code of Virginia defines important farmland as land that has historically produced or is producing agricultural or forestal products and is classified as Class I, II, III, Or IV; or consists of: 66 Prime farmlands - Lands that have the best combination of physical characteristics for the production of food, feed, fiber, forage, oilseed, and other agricultural crops with minimum inputs of fuel, fertilizer, pesticides, labor, and without intolerable soil erosion. Prime farmlands also include the above characteristics but are currently being used to produce livestock or timber. They do not include land already in, or committed to, urban development or water storage. Unique farmlands - Lands other than prime farmlands that are used for production of specific high-value food and fiber crops. They have the special combination of soil quality, location, growing season, and moisture supply needed to economically produce sustained high quality or high yields of specific crops when treated and managed according to acceptable farming methods. Examples of such crops include citrus, tree nuts, olives, cranberries, fruits including grapes and apples, and vegetables. Farmland - Lands other than prime or unique farmlands, that are of statewide or local importance for the production of food, feed, fiber, forage, or oilseed crops. Prime farmlands are identified in the Albemarle County Soil Survey. About 103,530 acres or 22 percent of the soils in Albemarle are prime agricultural soils, as defined by the Department of Agriculture. This includes all Class I and II soils not limited by wetness. In addition, the Natural Resource Conservation Service has defined by soil type: prime farmlands (suitable for cultivated crops and alfalfa hay in Albemarle), unique farmlands (suitable for orchards and vineyards in Albemarle) and locally important farmlands (suitable for alfalfa, mixed hay and pasture in Albemarle). These are listed in the Open Space Plan. All classes of soil are suitable for woodlands. The Natural Resource Conservation Service has defined by soil type: Hardwoods I (suitable for commercial production of Northern Red Oak, White Oak, Black Oak, Yellow Poplar, and Ash), Hardwoods II (suitable for commercial production of Chestnut Oak, Hickory, Scarlet Oak, and Southern red Oak), and soils suitable for commercial production of Loblolly Pine and. Virginia Pine. These are listed in the Open Space Plan. Protection Measures The most important protection measure in place to protect agricultural lands and forests is the Growth Management goal, and the Rural Area designation in this Comprehensive Plan. The Open Space Plan adopted in 1992 describes Important Farmlands and Forests as one of the four major open space systems, along with Major Stream Valleys, Mountains, and Civic/Cultural Features. Farmlands are identified on the Concept Map as large, contiguous, areas, currently open pasture, cropland, or orchards, which are not in a subdivision. Forests are identified as large, contiguous areas, currently forested, which have the best soils for hardwoods, and which are not in a subdivision. The Open Space Plan defines and lists farmland soils in Albemarle which are prime, unique, and locally important. It defines and lists forest soils in Albemarle according to their suitability for growing various hardwood or conifer species. The Open Space Plan also lists specific characteristics to determine the importance of farmland and forest land on a specific site. The RA, Rural Areas Zoning District implements the Rural Area designation through limitations on density and land uses. The Subdivision Ordinance is not usually included as a resource protection measure, however it should be reviewed to insure that it supports rural protection policies. Otherwise, it may inadvertently facilitate and encourage rural subdivisions which do not maximize protection of agricultural and forest lands. 67 All other protection measures for agricultural lands and forests are voluntary: The Rural Preservation Development (RPD) option protects agricultural lands and forests by allowing clustering of by-right lots with a large preservation tract secured with a permanent open space easement. The Use Value Assessment (land use tax) program allows for real caste tax deferrals with reduced assessments based on the actual use of the land for agriculture, forestry, horticulture, or open space. The Program is intended to encourage the preservation' of rUral lands and to relieve development pressures that might cause rural land conversion. Agricultural and Forestal Districts provide the landowner with certain tax benefits and restrictions on state agencies such as the Virginia Department of Highways, public utilities, and government action to protect the agricultural and forestal use of the land. In exchange, the landowner agrees to limit development of the property during the specified number of years (4-10 years) the district is in effect. Conservation or open space easements for the purpose of protecting natural, scenic or open space values are donated by the landowner to the Virginia Outdoors Foundation (VOF), the Albemarle County Recreational Facilities Authority, or other federal, state or local government agency or authorized private. charitable organization. Easements are individually negotiated agreements to limit development, but some ability to subdivide may be retained. Easements held in perpetuity offer landowners substantial income and estate tax savings at both federal and state levels. The American Farm and Ranch Protection Act adopted in 1997 allows exclusions from estates of a percentage of value of land subject to a conservation easement. A Pumhase of Development Rights (PDR) program is similar in effect to conservation easements, but the easement is purchased rather than donated. Financial incentives such as a PDR program are needed to encourage rural landowners, especially those not in a position to make a gift of development rights, to preserve their land as an alternative to sale for development. A PDR program is currently being developed by a committee appointed by the Board of Supervisors in 1997. Because a PDR program is limited by the availability of funds, it can provide only a limited, although effective, part of an overall resoume protection program. An ongoing public education program is necessary to acquaint the public, especially new residents, about the importance of preserving Alb'emarle's agricultural lands and forests. Albemarle County currently encourages agricultural and forestal districts and rural preservation developments in its planning efforts, and provides brochures explaining these programs to the public. Albemarle County participates in the annual Albemarle County Fair, and has supported and participated in two Albemarle County Farm Tours co-sponsored by the Albemarle County Farm Bureau and the Piedmont Environmental Council. Such events are invaluable in efforts to gain public support. Strategy: Actively promote and support voluntary measures to protect agricultural and forestry resources. See additional strategies under Easement Program and Public Lands, page ~ ,regarding conservation easements, purchase of development rights (PDR) and transfer of development rights (TDR). Strategy: Evaluate the existing agricultural and forestal districts program for effectiveness in helping to preserve agricultural and forestry resources, and evaluate and pursue additional incentives to increase membership in districts. 68 Strategy: Continue to support the use value assessment progran~ Strategy: Working with the Agricultural and forestal Districts Advisory Committee, develop and implement an active public education program to support and promote preservation of agricultural and forestry resources. Relation to Other Comprehensive Plan Policies The protection of agricultural and forestry resources complements the Rural Area policy but may potentially conflict to some extent with the biodiversity goal. Any potential conflicts should be considered in making land use decisions. The Rural Area policy establishes that agricultural and forestry uses are the desired land uses in the Rural Area, rather than residential uses. Residential development in the Rural Area often conflicts with agricultural or forestry uses and has an adverse impact on the continuance of agriculture or forestry in an area. For this reason, the Growth Management goal assigns highest priority to the protection of agricultural and forestry resources in the Rural Area. However, the Growth Management goal also affirms that purpose of the Rural Area is resource protection in general, for many types of resources. Maintenance of agricultural and forestry resources also provides an opportunity to conserve and efficiently use other resources such as: water resources (with use of proper conservation techniques); natural, scenic, and historic resources (with the maintenance of pasture and other agricultural land, and forested areas); and fiscal resources (by limiting development and lessening the need to provide public services to wide areas of the County). Protection of agricultural lands and forests promotes the goal ofbiodiversity by providing habitat for plant and animal species, but the cropping of agricultural and forestry products may conflict with that goal. It is important to recognize that both types of resources are important to the County's environment, and that both need. to be considered and provided for. The completion of a Biological Resources Inventory will provide more information about biological resources so that they can be adequately protected in the future. 69 Acreage in Land Use Acreage not in Land Use Total Development Areas 5,059 17,237 22,296 Rural Areas 308,432 . 134,312 442,744 Total 313,491 151,549 465,040 Notes: Total County land area is based on a total area of 726.625 square miles x 640 Acres per square mile - 465,040 acres.

Critical slopes are defined as areas with a slope of 25 percent or greater. Clearing, grading, building, cropping, and overgrazing of these lands can result in extensive erosion and landslides or sloughing of soil and lock; excessive stormwater runoff, increased siltation and sedimentation; loss of aesthetic resource; and, in the event of septic system failure, a greater travel distance of septic effluent. About 22 percent of the County acreage consists of critical slopes, as listed in the Soil Survey. About 20 percent of the County acreage is in slopes of 15-25 percent. Critical slopes are located throUghout the County, but especially in mountainous areas adjacent to the Shenandoah National Park, on both sides of Route 29 South, and east of Route 20 from Carter's Bridge to the Orange County line. Regulations to protect critical slopes by directing building and se. ptic system locations to more suitable terrain are · included in the Zoning Ordinance. CRTI'[CAL SLOPES STANDARDS The following GENERAL STANDARDS should be used in areas of critical slope: A. Avoid use of septic systems on slopes of 20 percent or greater. B. Avoid road construction on slopes of 15 percent or more. Roads should follow the natural topography in a manner to minimize grading, cutting, and filling. C. In areas of 15 percent or more slope, maintain natural drainage channels in their natural state and/or stabilize such channels to protect the natural drainage systems from impact of development activity. D. Design public utility corridors to fit the topography. "Straight line" and "up and over" alignment in areas sensitive to such routing should not be permitted. E. Adapt development to the topography and natural setting of the County rather than modifying the topography and natural setting to accbmmodate development. Excessive grading, cutting, and filling should be discouraged while imaginative and sensitive design should be encouraged. F. In farming and forestry, practice those activities appropriate to the soils and topography of the land. Generally, the soils of the County are not conducive to intensive agricultural and forestal uses when slopes exceed 15 percent. G. As land slope increases, the rate of stormwater runoff increases. Discourage applications of fertilizers, pesticides, herbicides and other chemicals in areas of steeP slope where they may be ineffective and can increase probabilities of surface and groundwater pollution. 78 Mountains [This Section Adopted by the Board of Supervisors August 5, 1998] GOAL: Recognize the value of Albemarle's mountains, including protecting water quality and drinking water reservoir capacity, soil conservation, forest resources, plant and animal habitat, scenic values, tourism, and the economic impact of these resources. ]:ntroduction Albemarle's mountains have been and continue to be a source of income, natural resources, scenic beauty, and recreation. Mountains may be said to define much of the character of Albemarle County. Directly and indirectly, the County's mountainous areas provide economic benefits to the local community in employment, tourism, and agricultural and forest products. Beyond the economic benefits, the mountains provide important natural functions, such as provision of clean water, contributions to healthy air, and habitats for many of the County's plant and animal species. And, to many residents, the blue backdrop of the mountains gives Albemarle County in large measure its "sense of place," that quality which makes this area a special place to its residents and visitors and one which is consistently ranked among the top places to live in the United States. Mountains are a source of concern when inappropriate development creates unwanted impacts to environmental and aesthetic resources and public safety. Environmental concerns include soil erosion, surface water runoff, septic system contamination, fragmentation of forests, and destruction of habitat. Aesthetic concerns center on disruption of the relatively pristine wooded character which provides a sense of continuity, natural beauty, and wilderness, and the resultant impact on tourism. Public safety concerns include difficult access for emergency vehicles, and the potential for debris flows. OBJECTIVE: Pursue additional protection measures to protect mountain resources and to promote public safety in these areas of exceptional critical slopes and higher elevations. Strategy: Develop a mountain protection district to protect and promo, te mountain resources and to protect public safety in mountain areas. Strategy: Develop an educational brochure with recommended design standards for mountain areas to encourage sensitive site design which is considerate of safety, environmental and aesthetic concerns. Strategy: Encourage voluntary measures which protect mountain resources, such as conservation easements, agricultural and forestal districts, and use value taxation. Strategy: Encourage the use of the Rural PreservaJion Development (RPD) option to protect mountain resources. Strategy: Utilize an acquisition program, such as purchase of development rights (PDR), to protect mountains. Strategy: I~hen enabling legislation allows, evaluate a density transfer or transfer of development rights(TDR) program to protect mountains. Strategy: Develop County planning tools and educational materials that address hazard avoidance with regard to areas that are prone to debris flows. In conjunction with appropriate resource agencies, develop a debris flow hazard map for Albemarle County. 79 Albemarle's Mountain Resources Albemarle's mountains are unique areas of the County which are distinguished by the natural resources and physical conditions listed below. Such resources and conditions are found in other areas of the County, but only in the mountains do they occur in such combination, as extensively, and to such extremes. CRITICAL SLOPES: Mountain areas are unique and distinct from the lower elevations of the County that also may contain critical slopes because mountains, by their nature, are a system of slopes that extend for greater distances than critical slopes at lower elevations and which may be considerably steeper. In Albemarle's mountains continuous critical slopes in excess of 50% can be found for distances of up to one mile, and in some cases, longer. Concerns regarding disturbance of steep land become pronounced in mountain areas due to generally shallow soils and length of grade on side slopes. Soil erosion, surface water runoff, and septic system contamination are amplified in these areas. SOIL: Forest cover is the optimum land use for minimizing soil erosion and maximizing water quality. Soils on steep slopes are typically more erodible than in other areas. Inaccessibility and isolated location of development sites in mountain areas necessitate longer driveways and access roads over more highly erodible soils than in other areas of the County. Such driveways and access roads may disturb many times more land area than a dwelling itself. Improper attention to soils may result in accelerated soil erosion and sedimentation, ground or surface water pollution, landslides, flooding, drainage problems; failed septic systems, construction problems; and unproductive agricultural and forestal lands. WATER QUALITY AND QUAN'ITi'Y: Sedimentation of Albemarle's public drinking water reservoirs in addition to increased demand may necessitate the building of an additional raw water source prior to 2015 to meet the average daily demands of the Urban Service Area. The South Rivanna Reservoir loses 13 million gallons of storage capacity annually as a result of sedimentation. The Ragged Mountain Reservoir, by contrast, loses no appreciable capacity. Protection of water resources is of vital importance to Albemarle County and Virginia in general. Albemarle's location adjacent to the Blue Ridge Mountains provides both the advantage of clean headwaters, and a responsibility to protect them. (See Water Resources, page -) FOREST AND AGRICULTURAL RESOURCES: The mountains of the County are almost entirely in forest cover, with the remaining acreage in orchards and pasture. A viable forest industry is an essential economic incentive to maintenance of forest land. The principal threat to the County's mountain forests and farms has now become fragmentation and conversion to residential land use. The County's Agricultural and Forestal Industries Support Committee report states, "Continued forest fragmentation is probably the biggest threat to the future viability of the forest industry in Albemarle County...As parcel size declines, operability for timber harvesting decreases. Forest sizes below 40 acres are difficult to manage economically. The proximity of houses and other structures escalates the problem." The Growth Management Goal of Albemarle County places highest priority on the protection of agricultural and forestry resources in the Rural Area. The Mountain areas are zoned almost exclusively Rural Areas. The Rabun-Myersville-Catoctin soil association on the Southwest-Carters Mountain chain is among the most productive hardwood forest soils in the Commonwealth. DEBRIS FLOWS: Some types of landslides take place very gradually, and while they can cause property damage, the landslide can be tracked and mitigation planned. Others types of landslides move very rapidly and have to potential to inflict massive damage to natural landscapes and human settlements. Debris flows (also called mudslides, mudflows, or debris avalanches) are fast-moving landslides that occur during periods of intense 8O rainfall. The U.S. Geological Survey (USGS) describes debris flows as follows: Fast moving flows of mud and rock, called debris flows, are among the most destructive types of landslides and are responsible for substantial damage and loss of life worldwide...Their consistency ranges from watery mud to stiff, rocky mud similar to wet concrete and dense enough to carry boulders, trees and cars .... Debris flows are triggered predominantly by adding moisture to soil on steep slopes faster than the moisture can drain away leading to a temporary condition of perched water in the soil .... They commonly start on steep hillsides as shallow soil slides that liquefy, accelerate to speeds of 35 miles per hour or more, and flow down hill slopes and channels until slowing on more gentle ground. The following debris flow events have occurred in 'recent times in our particular region of the Appalachian Mountain chain: · In 1969, during Hurricane Camille, Nelson County (and a small part of Southern Albemarle) experienced debris flows that caused 150 deaths and $100 million in property damage. · In November, 1985, widespread debris flows in Virginia and West Virginia in the Potomac and Cheat River basins led to 70 deaths and $1.3 billion in property damage. · In June, 1995, a storm cell in Madison County caused by 30 inches of rain during a 16 hour period resulted in debris flows that caused one fatality and $100 million in property damage. During the same period as the Madison County events, at least 100 debris flows occurred along the North Fork Moorman's River in Albemarle County and Shenandoah National Park. It is estimated that at least 11.5 inches of rain fell during a two-hour period. Were it not for the Sugar Hollow Reservoir, which acted as a trap for the debris flow flood surge from the North Fork Moorman's, eight or more downstream residences would almost certainly have been destroyed. In addition, scientists have documented 51 historical debris flow events between 1844 and 1985 in the Appalachians. Studies of debris flow sites have revealed old, prehistoric debris flows beneath deposits of modem debris flows, meaning that, in geologic time, debris flows are recurring events in the Appalachian region. While a debris flow may not return to the exact same geographic area (e.g., the North Fork Moorman's) for thousands of years, it is known that conditions promoting debris flows occur somewhere in the Appalachian region every two to three years, and, accordingly, somewhere along Virginia's Blue Ridge front approximately once every decade. Compared to other areas of the country, Central Virginia is not known as a region that is particularly vulnerable to natural hazards (e.g., earthquakes, volcanoes, etc.). However, floods and debris flows are certainly natural hazards that are known to occur in Central Virginia, and for which the population should be prepared. With regard to typical flooding, the County maintains a flood plain program in accordance with the National Flood Insurance Program., and regulates activities with in flood plains through the zoning ordinance. Debris flows, however, are not associated with a typical flood event, and until the events of June, 1995 (and Hurricane Camille for some) brought these realities to our door step, the community has remained largely unaware of this natural hazard. It is important for the County and the residents of mountain-side communities to realize that there are measures 81 that can be taken to avoid debris flow hazards and to be prepared. The U.S. Geological Survey recommends the following general measures: 1. Become familiar with the land around you. Learn whether debris flows have occurred in your area by contacting local officials, State geological surveys or departments of natural resources, and university departments of geology. Slopes where debris flows have occurred in the past are likely to experience them in the future. 2. Support your local government in efforts to develop and enforce land-use and building ordinances that - regulate construction in areas susceptible to landslides 'and debris flows. Buildings should be located away from steep slopes, streams and rivers, intehnittent-stream channels, and the mouths of mountain channels. Watch the patterns of storm-water drainage on slopes near your home, and note especially the places where runoff water converges, increasing flow over soil-covered slopes. Watch the hillsides around your home for any signs of land movement, such as small landslide~ or debris flows or progressively tilting trees. 4. Contact your local authorities to learn about the emergency response and evacuation plans for your area, and develop your own emergency plans for your family and business. In accordance with these recommendations, the County should enhance its planning and informational resources to direct and advise that development avoid debris flow-prone areas. In this regard, recent USGS studies have identified the following predictive criteria for potential future debris flows: · Storms with very intensive rainfall -- the 1995 storms had periods with rainfall intensities of 5 inches per hour that were sustained for 2 hours or more. · Areas underlain by prehistoric debris flow deposits. · Areas underlain by slopes greater than 26 degrees (approximately 47 percent slope). · Natural drainage channels and streams that originate on slopes greater than 26 degrees and delineated with a buffer 10 feet in elevation above the channel. The USGS has used these and other critieria to produce a hazard map for part of Madison County based on studies of the 1995 debris flows. Albemarle County should work with the appropriate agencies to produce a similar map for the County's mountain areas. The information in this section was derived from the following reports: Debris-Flow Hazards in Areas Affected by the June 27, 1995, Storm in Madison County, Virginia, Morgan, B.A., Wieczorek, R.H., Campbell, and Gori, P.L., USGS Open-File Report 97-438, 1997.

Those declines are caused by several factors, most importantly, fragmentation of habitat - the dividing of large areas into smaller parcels, and the resulting disruption of forest cover. (See Biodiversity, page -, and Forest Fragmentation, page -). SCENIC RESOURCES AND THEIR ECONOMIC IMPACT: Albemarle County is well known for its scenic character. Maintaining this character is important to current residents and to prospective residents and tourists. A number of highly visible structures constructed recently have occasioned public concern about the continued scenic quality of the mountain landscape. Public expression of concern suggests that the scenic quality of the mountains is important to County residents. An issue that is of importance to visual impact is the horizon. In a county with as much varied topography as Albemarle, the natural horizon becomes very prominent. Any serious modification of the natural ridge lines in the County will modify the visual character of an entire area. (See Scenic Resources, page -). DARK SKY: Excessive outdoor lighting in the urban and developed areas of the County is increasing. The natural resource of dark night sky and its importance to the University's Observatories has been insufficiently considered in planning processes in the County. Energy wasted nationally from poorly designed outdoor lighting amounts to more than a billion dollars a year (International Dark Sky Association, 1990)~ Poorly designed outdoor lighting creates glare, which compromises safety especially for drivers, degrades the quality of the entrance corridors leading to the City, and degrades the quality of the built environment. (See The Dark Sky, page -). TOURISM: Tourism and associated economic benefits related to the mountains continue to grow in the County. Travel sales in 1994 accounted for 17% of total sales or $109,139,211 in the County. Each year approximately 1,985,000 people visit Shenandoah National Park. Direct economic benefit to counties adjoining the Park is approximately 85 million dollars per year. In 1990 there were 550,183 visitors to Monticello, which translates into over 159 million dollars in revenue to the County. History of Mountain Protection Mountain resource protection efforts began in 1971 with the adoption of the County's first Comprehensive Plan, which delineated the mountains as "conservation areas." The 1977 Comprehensive Plan contained a map of conservation areas which included hilltops, major ridge lines, and slopes over 15%. Hillside development standards were proposed on slopes exceeding 15%, which included road construction, grading and drainage standards. In 1980 a new zoning ordinance was adopted, which included the Rural Areas zoning district to restrict rural development rights, and the critical slopes provisions. All the.mountains except two small peaks in the Urban Development Area are currently zoned Rural Areas. The critical slopes provisions require a "building site," a contiguous area of land in slopes of less than 25%. The regulation is intended to implement the Comprehensive Plan by protecting and conserving steep hillsides together with public drinking water supplies and flood plain areas and in recognition of increased potential for soil erosion, sedimentation, water pollution and septic disposal problems associated with the development of those areas described in the Comprehensive Plan as critical slopes. The '1980 critical slopes provisions did not address driveway construction. The 1982 Comprehensive Plan included environmental standards to protect and conserve natural resources. The Plan states: "Clearing, grading, building, cropping or overgrazing of critical slopes can result in extensive erosion and landslides or sloughing of soil and rock; excessive storm water runoff; increased siltation and sedimentation of natural and man-made bodies of water; loss of aesthetic resource and in the event of septic 83 'system failure, a greater travel distance of septic effluent." The 1989 Comprehensive Plan states that, "Natural, scenic, and historic resources are essential to Albemarle County's rural character, economic vitality and quality of life." The Plan notes the strong relationship between these environmental resources, water supply protection, and agricultural/forestry preservation, which are the major reasons for protecting the Rural Area. The Plan also notes the interdependency of environmental · resources, "For example, the maintenance of forested areas protects surface water quality, wildlife habitat, critical slopes, groundwater recharge areas, and air quality." The 1989 Plan also discusses design standards for scenic resources. "In a county with as much varied topography as Albemarle, the natural horizon becomes very prominent. Any serious modification of the natural ridge lines in the County will modify the visual character of an entire area." The Plan recommended adoption of an Open Space and Critical Resources Plan, to identify and to develop protection measures for significant natural and scenic resources, including critical slopes, important wildlife habitat, wooded areas of environmental importance, and hilltops and ridges. The Open Space Plan, adopted July 15, 1992 as an amendment to the Comprehensive Plan, identifies Mountains .as one of four major open space systems which are the most important open space lands to protect. It lists resources associated with mountains: critical slopes, scenic views, wildlife habitat, extensive forests, unique soils for orchards, natural areas (including geologic features, and habitats for rare and endangered plants and animals), and headwaters. The Open Space Plan defines mountains by a designated elevation contour line, based generally on location of critical slopes and areas of visual impact. The Open Space Plan includes the following strategy which was also added to the Comprehensive Plan action agenda: "Develop a mountain protection district to protect the scenic and aesthetic values associated with mountains, and to further protect their environmental characteristics." The Open Space Plan states: "Visual concerns related to mountains center on disruption of the relatively pristine wooded character which provides a sense of continuity, natural beauty, and wilderness. Extensive critical slopes, combined with high elevations, result in a prominent display of changes to the mountain landscape. Activities which alter the continuity of the ridgeline or~esult in excessiVe tree removal should be discouraged. Environmental concerns include (1) the loss to development of a unique and beneficial natural environment and (2) disruption of the natural balance of soils, slope and vegetation. While detailed studies have not been undertaken at this time, it is anticipated that due to the location of generally unspoiled and extensive forests, together with a relatively small human and domestic animal population, mountains may be areas of comparative significance as "natural areas" and "wildlife habitats." Mountains also provide areas of unique soils suitable for orchards and vineyards between elevations of 800 - 1800 feet. Environmental benefits of undisturbed forests often associated with mountains include increased groundwater recharge, surface water quality, and climate modulation. In addition, concerns regarding disturbance of steep land become pronounced in mountainous regions due to generally shallow soils and length of grade on side slopes. Issues related to soil erosion, surface water runoff, and septic system contamination are amplified in these areas." Mountain Protection Plan The Mountain Protection Committee consisting of 12 citizens appointed by the Board of Supervisors met from June, 1995 through July, 1996. They prepared a report, the Proposed Mountain Protection Plan (Appendix) dated August 1, 1996, which was presented to the Board of Supervisors September 4, 1996. The plan contained three major recommendations: (1) Delineation of a Mountain Overlay District describing the area containing the critical resources of the mountains, and recommendations which ensure health and safety of the mountain area's residents and which 84 control possible degradation of County's resources from activities within the District. The intent of an ordinance would be to protect resources characteristic of or dependent on the mountainous regions of the County: public safety, water quality, public drinking water reservoir capacity, soil conservation, forest resources, plant and animal habitat, scenic values associated with the mountains and their economic impact, and tourism. Specific recommendations for a Mountain Overlay District addressed soil erosion plans, driveway requirements, protection of ridge areas, and building and subdivision requirements to use building sites located outside the mountain district if they are available. (2) Recommendation of County-wide application: Lighting Ordinance to require shielding of all new exterior lighting fixtures. The Committee also recommended a future study to determine maximum foot candles for categories of uses, and recommended that the Board of Supervisors ask power companies to cease promoting unshielded and inefficient lighting. (See The Dark Sky, page-) (3) Additional Planning Tools: Though the Mountain Protection Committee's task was to develop. recommendations for the protection of the mountains of the County, the Committee noted that planning for the protection of discrete areas or resources, such as the mountains, the urban areas, or the watershed must be integrated with a more systematic approach which provides for the protection of resource systems, such as drinking water, economic viability of urban areas, or transportation networks. The mountainous areas of Albemarle County are not only prominent physical features possessing critical natural resources, but they are also important parts of many human and natural systems in the County and region. Like other County human, cultural and natural resources, they therefore require consideration as components of larger planning issues. Some of the County's land use regulations developed with a compartmentalized approach to land planning may have unintended consequences for protection of its natural resources and other comprehensive planning goals of the County. Rural residential parcels (5-20 ac.) too small to farm o.r timber or serve as habitat, increase sprawl, put unintended pressure on mountain and agricultural lands. Areas of the County possessing critical resources may require different types of land use restrictions to protect the resource. Segregated land uses may unintentionally increase housing costs, and increase pressure on transportation systems and on agricultural lands in the path of proposed new roads. Discussion of natural resource protection may not be broad enough in scope to suggest effective or equitable solutions. The Committee recommended several planning tools to achieve a more systematic approach to resource protection for Albemarle County. MOUNTAIN DESIGN STANDARDS The following GENERAL STANDARDS should be applied to protect Mountain resources: · Minimize clearing. Consider the impact of your clearing on others' vistas of the unspoiled natural terrain. Locate driveways to minimize grading, length, and impact on critical slopes and trees. Driveways should disturb no more than 65 feet in cross section. Consider "peek holes" in the vegetation and winter views rather than clearing for year-round views. Maintain the natural tree canopy. Replant the forest edge with local indigenous species to discourage growth of undesirable edge vegetation (poison ivy, greenbriars). · Locate the house and structures to make them unobtrusive in the landscape. Do not build structures taller than the natural tree canopy. 85 Do not locate the house and structures where they will be "skylighted" against the horizon. Do not alter the continuity of the ridgeline. · Locate the house and structures to make them safe. Do not build in swales or other areas where a debris flow may occur. Minimize disturbances to critical slopes. Locate the septic system downslope of the dwelling to make use of the clearing as a fire buffer area. · Design private driveways to permit fire and rescue ~mergency vehicle access: Longitudinal gradient should not exceed 16%. Minimum allowable radius for horizontal curvature should be 40 feet. Avoid north slopes where snow and ice may accumulate. · Design the house and structures to blend in with the terrain surrounding the building site. Choose non-reflective colors and materials. Choose earth tone colors rather than stark white. Choose underground rather than overhead electrical service. Choose local indigenous landscape materials. Consider an alternative to growing a lawn. · Consider your impact on plant and animal habitat. Maintain the natural landscape in large contiguous areas, Clearing for a dwelling creates edge habitat. Be prepared to coexist with deer and other wildlife. · Locate and shield exterior lighting to minimize its obtrusiveness on neighbors and the natural environment. Use full cutoff fixtures which are aimed downward. Use lighting which is adequate but notexcessive for the proposed use. 86 MOUNTAIN CONTOUR LIST The following named mountains and other unnamed mountains are included on the Concept Map (USGS quad sheet locations are noted if names are duplicated).

Graphics and Information Resources (OOMGAIR) 88 The Dark Sky GOAL: Protect the dark sky of Albemarle County as one among our many natural, scenic, scientific and cultural resources, for the benefit of residents, visitors, and the larger scientific community, now and in the future. Introduction The night sky historically has been a source of beauty and value to people and cultures throughout the world. In this century, astronomical research has generated information and technology that we now use in our daily lives, and space exploration promises to grow. Aside from scientific and aesthetic considerations, cycles of daylight and darkness have ecological consequences. Bright lights on tall buildings confuse migratory birds, and deciduous trees near streetlights retain their leaves too late in the year. Our lives are affected by the night sky in numerous ways, some not yet fully understood. Albemarle's clear skies and dark nights are more than just a scenic resource to the County. Our official appreciation for the dark sky may have begun with Thomas Jefferson and his design for an observatory at the Academical Village. Leander McCormick further encouraged the community's interest in astronomy with his generous endowment of the refracting telescope at University of Virginia. Later, with construction of the Fan Mountain station near Covesville, Albemarle County became home to the largest and only major optical observatory at a dark site east of the Mississippi River. The ability to see the stars clearly has been a strong if unexpressed part of the region's beauty, and a real influence on the county's development. Light Pollution Obtrusive lighting, often referred to as light pollution, obscures Our view of the sky and primarily comes from inefficient and misdirected lighting sources costing this country alone more than $I billion each year. Scientists refer to it as urban sky glow; motorists know it as glare; consumer advocates lobby against it as energy waste; neighbors call it light trespass and, often, a nuisance. Simply defined, it is too much light shining in the wrong direction. It not only fails to accomplish its purpose, it often creates problems where there were none. Urban sky glow results from unshielded light shining upward, creating a glow which obscures the night sky and can even disrupt ecological patterns in plants and animals. Under ideal conditions, 2,500 stars and the Milky Way galaxy are visible from horizon to horizon; in a moderately illuminated'suburb, because of sky glow only 200 to 300 stars can be seen. Glare occurs when one can see light directly from the fixture or bulb, dazzling the eye and reducing the effectiveness of the emitted light. In response to glare, the human eye undergoes a process known as transient adaptation: the pupil must rapidly adjust in size to go from eXtreme light back to darkness. Not only is this transition taxing to the eye, but at times it cannot be accomplished quickly enough to avoid accidents. With our eyes straggling to adapt from high to low light, we are blind to things we would normally see. Glare degrades the quality of the built environment, as increasingly elevated levels of illumination are needed to overcome its impacts. Lighting accounts for 20 to 25 percent of all electricity sold in the United States. According to some estimates, as much as $1 billion may be wasted annually as a result of inefficient lighting sources. Quality lighting is well shielded, uses the right amount of light, directs the light where it is needed, and uses energy efficient lighting sources. In addition to the direct cost savings, installation of quality lighting would ultimately result in less coal burned (the source of most electrical power in the United States), thereby reducing air pollution and acid rain. The economic benefit of efficient energy use thus complements protection of the dark sky resource. 89 Light trespass occurs when lighting is not confined to the originating property. Spill light falling over property lines can illuminate adjacent grounds or buildings in an objectionable manner, interfering with the owner's enjoyment of his property, privacy and view of the night sky. The nuisance resulting from light trespass often forces government to be the arbitrator of disputes. "Good neighbor development" includes careful attention to quality lighting, both in rural and urban neighborhoods. Light pollution is not the inevitable price of progress. There are many remedies, and in fact this kind of pollution is not difficult to reduce. It does require education and commitment: education, because even some lighting professionals are not aware of the problem; and commitment, because there are many lights throughout this community and others which are inefficient and poorly installed. Lighting Fallacies Misconceptions about lighting abound, some so common we never question them and thus perpetuate the problem in our own homes and communities. 1. "The more lights the better." Although we need well lit main streets and pedestrian areas, security lights, and parking lot lighting, we do not need glare, competing lights, light trespass and energy waste. Lights should be effective, not just numerous. 2. "Light pollution only affects astronomers." School children need to see the Milky Way as much as astronomers do, if for different reasons. Our cultural traditions have developed around the mysteries of the natural world, part of which is the vast night sky. Space exploration, and the host of everyday applications it has brought with it, occupies a central part of twentieth century history, and there will be more discoveries in the future. School children today may be working in space tomorrow, and if not, they will be citizens charged with appreciating and protecting the world around them. 3. "You can get away from the lights if you drive out of town." One shouldn't have to take a vacation to see the night sky, when quality lighting is available and often less expensive than conventional fixtures. Many Americans live in urban corridors so large that it isn't practical to drive out of town just to enjoy the stars. 4. "It's too late to do anything." Our awareness of light pollution is recent, and it will take sustained effort to change the habit ofoverlighting. Nonetheless, it is a problem that can readily be solved with available technology. Education is the key. 5. "Security lights prevent crime." No one really knows if outdoor nighttime lighting prevents crime. It can deter illegal activity by making it more visible, and it can also make a house or business a more convenient target. Most crimes take place during the day. If outdoor security lights are needed, there are many to choose from and many installations that are effective but nor polluting. What Is Good Lighting? Good lighting serves the user, and thus will vary according to the site and circumstance. lighting include but are not limited to: Characteristics of good 1. It provides adequate lighting for the task, but does not over-light. 2. Lighting fixtures are fully shielded, so that no light is emitted above the horizontal plane and there is little or no glare. 3. Lighting fixtures are carefully installed to maximize effectiveness on the targeted area and minimize or 90 eliminate adverse impact beyond the property borders. 4. It utilizes fixtures with high-efficiency lamps which meet the light-color needs ofthedesign criteria. Examples of common lighting fixtures are included in Figure 1. Lighting Ordinance On September 4, 1996, the Albemarle County Board of Supervisors adopted a Resolution of Intent to amend the Zoning Ordinance to regulate outdoor lighting for all uses in all zoning districts, directing the Planning Commission to hold a public hearing and send its recommendation to the Board at the earliest possible date. Dark Sky tours were organized in the Spring of 1997 by the Department of Astronomy at University of Virginia for City and County officials, community businesses and .citizen groups. The Planning Commission recommended approval of a lighting ordinance in April, 1998 and forwarded it to the Board of Supervisors. The ordinance was adopted by the Board of Supervisors on August 12, 1998. Amendments to the Zoning Ordinance and other initiatives related to protection of the quality of our night sky should be based on the following objectives: OBJECTIVE: Reduce light pollution caused by uplighting, excessive overlighting, glare and light trespass. OBJECTIVE: Promote lighting energy efficiency, thereby conserving private and public funds, while providing adequate lighting for the tusk. OBJECTIVE: Provide a safe and secure developed environment, through quality lighting design which minimizes glare and avoids creating dark areas near well lit areas. OBJECTIVE: Protect the public and private investment in McCormick and Fan Mountain Observatories through Dark Sky initiatives, in the interest of scientific research, public education, and future economic development opportunities. If the lighting ordinance is to be accepted and implemented in a timely and effective manner, the parties involved in the development process - property owners, the business community, government, and the construction industry - must understand the value of dark skies and good lighting. An educational program is needed, one which adopts a proactive approach and draws upon the resources available in the community. Strategy: Adopt a lighting ordinance which requires that all exterior fixtures be fully shieldea[ Strategy: Establish an advisory committee composed of representatives from business, astronomy (professional and amateur), public uttTities and/or agencies, design and construction industries, county residents (urban and rural), and local community organizations, to undertake the following tasks: - Evaluate current lighting practices; - Identify dark sky/lighting issues and concerns in Albemarle County; - Review ordinances from other jurisdictions; Study and recommend as necessary additional lighting provisions to the Planning 'Commission, including by not limited to an ordinance to phase .in shielding of existing lighting and establish maximum foot candle requirements for categories of uses. 91 Strategy: Develop a community-based educational program: Adoption of resolution by Board of Supervisors asking power companies to cease promoting unshielded and inefficient outdoor lighting in the County; Initiate public information and education programs about dark sky and lighting topics in cooperation with the University of Virginia McCormick and Fan Mountain Observatories and other interested parties; Develop workshops on technical lighting topics, for individuals in the building materials, electrical contracting, design, construction, and associated industries, and individual homeowners; Explore the feasibility of Albemarle County participating in the Green Lights Program established by the Environmental Protection Agency. 92 Figure 1 EXAMPLES OF COMMON LIGHTING FIXTURES sFmV~LDED LIGltTING UNS[mV.

In both the Rural Area and Development Areas, preservation of forests and wooded areas is important because they provide multiple benefits to the environment. However, in the Rural Area, active forestry including the harvesting of timber is an appropriate use which is consistent with the purposes of this Plan. In Development Areas, wooded areas are important to preserve along drainage swales, streams and critical slopes; along hillsides and ridges; and other areas where existing vegetation is important for visual, environmental, or recreational reasons. In these areas, trees should be preserved or established as development occurs. Wooded areas are necessary for the maintenance of ground and surface water quality, groundwater recharge area, and habitat for biological resources. Undisturbed wooded areas protect critical slopes and prevent surface runoff, flooding, soil erosion and sedimentation. Wooded areas provide shade and windbreaks, improve air qUality, and reduce dust, noise, and glare. On a large scale, wooded areas absorb carbon dioxide and other pollutants, and modulate temperatures, thereby affecting the general climate over an extended period of time. Wooded areas also provide buffers and recreational opportunities. These are important benefits and amenities which make the Development areas more attractive places to live. OBJECTIVE: Encourage the preservation of existing wooded areas as development occurs in Development Areas. Maintain or establish wooded buffer areas between dissimilar land uses as development occurs. Strategy: Preserve or establish trees or vegetative buffers in the following specific areas as development occurs: The wooded ridge along Berkmar Drive Extended which is highly visible from Route 29 NOrth and provides a buffer between adjacent residential and commercial land uses; The Whitewood Road Park which is the last significant wooded area in an intensively developed residential neighborhood; The wooded areas along Route 663 and Route 743 which define the entrances to Earlysville; The wooded slopes of Stillhouse Mountain, Lewis Mountain, Mount Jefferson, and the Ragged Mountains in Neighborhood Six which are highly visible in the Urban Arem These areas include the mountains as well as the wooded, critical slopes outside the mountain designations. The area between the southern boundary of Hollymead Community (Route 643) and the northern boundary of the Urban Area (South Fork Rivanna River), which provides a buffer area necessary to maintain the distinct identity of each Development Area; Existing wooded areas along heavily travelled entrance corridors.such as the Route 29/250 Bypass and Interstate 64 which protect the visual quality and character of the area as seen from the roadways, and provides a buffer between the roadways and adjacent residential areas; · Along Route 29 South as it passes through North Garden; 94 The wooded areas visible from Monticello, especially in Neighborhoods Three and Four, which protect Monticello's setting and viewshed; Incorporate into the plans for the proposed Meadowcreek Parkway and the Route $3 parkway buffer areas along the roadways; Maintain or establish buffer areas between regional, community or industrial service areas and residential or Rural Area; Where Development Area boundaries are defined by natural features such as stream valleys or mountains, maintain such boundaries as buffer areas. 95 Soils Soils are a natural resource which require proper use and preservation. It is important that the use of the soil be related to its suitability and limitations. Improper use of soils may result in accelerated soil erosion and sedimentation, ground or surface water pollution, debris flows, flooding, drainage problems, failed septic systems, construction problems, and unproductive agricultural and forestal lands. To prevent these problems, development · should be avoided on soils with severe limitations due to drainage, flooding, slope, shallow depth to rock, or shrink-swell characteristics. Some, but not all, of these limitations can be reduced by methods which add to the difficulty and cost of construction. The most environmentally sensible approach is to consider and adapt to soil types in the planning and design of development. The Open Space Plan identifies sensitive soils. Soils which are restricted due to flooding or wetness are generally not buildable. Soils restricted by shalloTM depth to rock may hinder installation of septic systems and basements. In either case, sensitive soils generally indicate areas best left in open space on a particular site. · Existing regulations which address the proper use of soils include the Water Protection Ordinance, and Critical Slopes and Site Plan regulations in the Zoning Ordinance which require that the soils be reviewed as to suitability for the intended develoPment. Special design measures may be recommended where soils are rated poor or severely limited for the intended use, or where high seasonal water table and/or high runoff potential is encountered. In the Rural Area, important farmland soil can be identified and preserved for agricultural and forestry use. Protecting the best soils for agriculture and forestry is consistent with the decision to give highest priority to these land uses in the Rural Area. It is desirable that rural development be directed away from soils which are suited for agricultural production. Important farmland soils are discussed further under Agricultural and Forestry Resources, page --. The Open Space Plan identifies prime, unique and locally important farmland soils, and the best soils for commercial production of various hardwoods and conifer species. A Soil Survey of Albemarle County, Virginia was issued in August, 1985, by the U.S. Department of Agriculture and the Soil Conservation Service. The survey includes general and detailed soil maps, descriptions of the soils, and the suitability, limitations, and management of the soils for specified uses. The general soil map (Page --) shows eight soil association areas of similar soils, relief, and drainage. The general soil map can be used to compare the suitability of large areas for general land uses, but is not useful for planning a particular site. The detailed soil maps found in the Soil Survey along with soil map unit descriptions can be used to plan and design a specific site. Strategy: Continue to consider soil suitability and limitations as criteria for review of the planning and design of development proposals. Strategy: Continue to preserve important farmland soil for agricultural and forestry use. 96 Air The Department of Environmental Quality (DEQ) is responsible for administering the Federal Clean Air Act of 1970 and subsequent enactments by the Virginia General Assembly. The. DEQ monitors for six criteria pollutants set by the Environmental Protection Agency: total suspended particulates, carbon monoxide, sulfur dioxide, nitrogen oxides, ozone, and lead. The DEQ enforces federal standards for eight hazardous air pollutants through a review process for new and modified sources. The_DEQ also regulates offensive odors and open burning. In the Charlottesville area, only particulates are monitored at a station located on top of City Hall. In 1997, the annual arithmetic mean was 21 micrograms per cubic meter, well below the standard of 50 micograms per cubic meter. Ozone standards are probably exceeded at certain times of the year, according to a DEQ representative, but monitoring equipment is not available in this area. Other environmental problems associated with air quality are acid rain, impaired visibility of scenic resources, and radon gas. Acid rain is caused by sulfur dioxide and nitrogen oxides which are converted in the atmosphere into sulfuric or nitric acid. It is probable that distant sources of sulfur dioxide - including coal-fi'red power plants in the Midwest -. are responsible for the acid rain problem in Virginia. Adverse effects include decline of lakes and aquatic life, reduced yields and growth of crops and forests, and deterioration of buildings and statues. The Clean Air Act requires protection for visibility in areas designated as "Class I" by Congress. The Shenandoah National Park is one of two such areas in the state. Radon is a radioactive gas produced by the decay of uranium and radium in the ground. The Environmental Protection Agency has recommended that homeowners should take steps to reduce the level of radon in their homes if it exceeds four picocuries per liter. The State Health Department can provide information on radon and approved radon testing firms. The County does not enforce air quality regulations. Public inquiries and requests for permits In Albemarle County should be directed to the Department of Environmental Quality's Regional Office in Fredericksburg. Virtually all industrial development or expansion, and most large commercial and residential construction require a permit. Early contact with the DEQ will clarify specific requirements. Strategy: To protect air quality, promote alternatives to single-occupancy vehicles, such as pedestrian sidewalks, bicycle use, ride-sharing, and public transit services. See page 180, Land Use Plan. Strategy: Monitor federal and state laws and the activities of agencies which affect air quality in this locality. 97 Mineral Resources Mineral production in Albemarle is limited to crushed stone and sand_and gravel. During 1995, more than 1,145,000 short tons of gneiss, greenstone, and sand and gravel were produced in the County. Crushed stone of meta-basalt or greenstone is produced near Shadwell, and crushed stone °f granite gneiss is produced at Red Hill for roadstone, asphalt stone, and concrete aggregate. Sand is produced at two locations on the Rivanna River. A crushed stone quarry near the South Fork Rivanna Reservoir and a soapstone quarry near Alberene are no longer in operationi Soapstone is a relatively important mineral in Albemarle, and PrOduction COuld be economically viable. Soapstone was quarried in the southern part of the County until 1995; the company had produced soapstone fireplaces, wood stoves, and other products. Other minerals and rocks found within the County which have been produced in the past include iron ore, slate, clay, sandstone, and limestone. Other minerals known to exist in Albemarle, are amethysts, asbestos, barite, copper, felsite, garnets, gold, limonite, hematite, and pyrite. There are currently thirteen parcels in Albemarle County with owned or leased mineral rights. It is not intended that mineral resources be protected like other natural resources. There are two concerns: that mineral resource production should not conflict with adjacent land uses, and that mineral resource extraction should be accomplished without adverse effects to other environmental resources or the public health safety, and welfare. Regulation is currently provide by the Natural Resource Extraction Overlay District in the Zoning Ordinance. MINERAL RESOURCE STANDARDS The following GENERAL STANDARDS should be followed for mineral resources: A. Avoid development of natural resource extraction areas where.incompatible to existing or proposed development. B. Include analysis of geological formations in terms of shockwave transmission in review of proposed developments in proximity to active mining operations involving blasting. C. Require disclosure of mineral rights leasing as a part of rezoning, subdivision, site plan, and other applications for County review. In the case of land subdivision, a prominent disclosure statement regarding leased mineral rights shall be required on the'subdivision plat. D. Prohibit dredging operations during the months of March through June to protect the aquatic environment during spawning/mating season and the following months of egg incubation and larval development. 98 · Scenic Resources GOAL: Preserve the County's scenic resources as being essential to the County's character, economic vitality and quality of lif~ Introduction Albemarle's outstanding scenic resources include the natural landscape such as mountains, rolling topography, water features, forests and wildlife; and the cultural landscape such as fenced fields with grazing livestock, farm buildings, historic architecture, crossroads villages~ and gardens. Albemarle's scenic resources are held in high value by its citizens and, therefore, merit special attention and consideration. Scenic resources contribute to the community's desirability as a place to live, they enhance and protect property values, and contribute to the overall quality of life. Albemarle's scenic quality is largely dependent on its agricultural and forestry resources and its historic resources. The combination of open and forested areas, natural scenes and ordered landscapes provide a variety of visual experiences which Albemarle's residents have long appreciated. The preservation of agricultural and forestry lands and activities and the preservation of historic resources and their settings are the most effective types of scenic protection in the Rural Area. Albemarle's scenic resources are important to visitors as well as its residents. The Blue Ridge Mountains and Albemarle's historic structures in their rural setting generate a year-round tourism industry. Visitors to these destinations gather a lasting impression of Albemarle as they travel our scenic roadways. Greenways will provide a firsthand opportunity for residents and visitors to enjoy scenic streams such as the Rivanna River. In the Development Areas, aesthetics is an important component of a quality built environment. The character of our community is determined not only by the design of individual structures, but also by the relationship of buildings to land forms and Vegetation, and by larger patterns of development. Good ui!ban design which respects the existing natural and cultural landscape and creates new urban open spaces (see page --), is essential to maintain this character and create attractive and functional new neighborhoods. Protection Measures Planning for aesthetics means that scenic resources are identified and purposefully preserved for the enjoyment of current and future residents and tourists. Preservation of scenic resources is often voluntary, or occurs indirectly as the result of natural resource protection. Regulations with aesthetic objectives usually include other acceptable objectives to support the aesthetic ones. In Albemarle, aesthetic protection is one of the stated objectives of the following regulations: · Rural Areas zoning district, intended for "conservation of natural, scenic, and historic resources," and "to preserve the County's active farms and best agricultural and forestal lands;" (Zoning Ordinance, p. 88) · Entrance Corridor overlay district, intended to "protect and enhance the County's attractiveness to tourists and other visitors;" (Zoning Ordinance, p. 198.1) · Critical Slopes provisions which limit development on steep hillsides to prevent "loss of the aesthetic resource;" (Zoning Ordinance, p.23) · Site Plan landscaping and screening requirements; and · Scenic Streams overlay district. An example of a regulation intended to protect a natural resource, but which indirectly protects a scenic resource, 99 is the Comprehensive Water Resources Ordinance. The required stream buffers which preserve indigenous vegetation to protect the water quality also protect the scenic quality of the streams. Voluntary measures which protect scenic resources are: · Conservation easements and historic easements, which are intended to preserve open space and historic resources; · Agricultural/forestal districts, which are intended to conserve and protect agricultural and forestal lands for aesthetic purposes, among others; and · Rural Preservation Developments, which are reviewed f6r conservation of natural, scenic or historic resources. In addition, the use value taxation program (land use tax) indirectly, but effectively, helps protect scenic areas through the maintenance of agricultural, forestal and open space areas. Honorific designations such as State Scenic River, Virginia Byway, Virginia Landmarks Register and National Register of Historic Places do not impose restrictions, but serve to draw attention to scenic resources and thereby encourage their protection. The strategies listed below address scenic roads and streams. Additional strategies which serve to protect other scenic resources such as open space, mOUntains, farmlands and forests, greenways, and historic resources are found in those sections. Scenic Designations: Roads OBJECTIVE: Maintain the visual integrity of all of ~llbemarle's roadways. Ali of Albemarle's roadways are important to protect for the impression which they convey to residents and visitors alike. Design standards should be used to help maintain the visual integrity of all roadways. In addition, there are specific roads in the County which stand out as exceptionally scenic roadways, and deserve particular attention as such. These roads usually serve as major tourist routes, and offer scenery representing the best of Albemarle' s varied terrain, water features, forests and agricultural use, architectural and landscape design heritage. Some of these roads may themselves be historic routes of travel in the region. These scenic roadways should be identified and protected as much as possible. Currently, scenic road designations include State-designated Virginia Byways and State Scenic Highways, and locally-designated Entrance Corridors. STATE DESIGNATIONS: VIRGINIA BYWAYS AND STATE SCENIC HIGHWAYS A Virginia Byway is an existing road with relatively significant aesthetic and cultural values, leading to or lying within an area of historic, natural, or recreational significance. A Virginia Byway designation does not place any restrictions upon properties along the Byway. The primary purpose is to give formal recognition to deserving roads and to further the creation of a system of roads to promote tourism and public appreciation of natural and historic resources. The following roads are currently designated as Virginia Byways: Route 6 (Irish Road) Route 20 North (Stony Point Road) Route 20 South (Scottsville Road) Routes 22/231 (Louisa Road/Gordonsville Road) Route 151 (Critzer's Shop Road) Route 250 West (Ivy Road/Rockfish Gap Turnpike) 100 Routes 601/676/614 (Old Garth Road "21 Curves"/Garth Road/White Hall Road) The 1996 Virginia Outdoors Plan recommends that Routes 53, and Routes 692/712 between Route 20 South and Route 29 South be considered for Virginia Byways. A State Scenic Highway is a road designed and built within a protected corridor. Skyline Drive is one of four such scenic highways in the State, and was constructed in conjunction with the Shenandoah National Park. LOCAl DESIGNATIONS: ENTRANCE CORRIDORS Protection for locally designated scenic highways was previously provided through the County Scenic Highway 'overlay district, which required increased setbacks for structures and parking lots, and additional sign regulations. That provision was deleted in 1992 following the adoption of the Entrance COrridor (EC) overlay district in i990. The motivation for removing the County Scenic Highway overlay district was the belief that the Entrance Corridor overlay would provide a broader and more effective measure of protection for scenic highway corridors. The purpose and intent of EC regulations is to ensure quality development compatible with the County's natural, scenic, historic, architectural and cultural resources. The EC overlay district provides for review of new construction along designated roads by an architectural review board under design guidelines. The following roads are currently designated as Entrance Corridors: Route 6 (Irish Road) Route 20 North (Stony Point Road) Route 20 South (Scottsville Road) Route 22 (Louisa Road) Route 29 North (Seminole Trail) Route 29 South (Monacan Trail Road) Route 29 Business (Fontaine Avenue) Route 29/250 Bypass Route 53 (Thomas Jefferson Parkway) Interstate 64 Route 151 (Critzer' s Shop Road) Route 231 (Gordonsville Road) Route 240 (Three Notch'd Road/Crozet Avenue) Route 250 East (Richmond Road) Route 250 West (Ivy Road/Rockfish Gap Turnpike) Route 631 from Charlottesville City limits to Route 708 (Stagecoach Road/Old Lynchburg Road) Route 654 (Barracks Road) Route 742 (Avon Street Ext.) There are several distinctions between the EC regulations and the previous Scenic Highway regulations. (1) EC regulations may be applied only to "arterial streets or highways found to be significant routes of tourist access;" so that a road may not qualify based on classification alone. (2) EC regulations do not specify a setback, the major distinction from the Scenic Highway regulations which required a 150 ft. setback. In this regard, the EC regulations provide more flexibility, but may overlook an important technique for visual protection. (3) EC regulations do not apply to residential buildings unless a site plan is required, Which means that single family homes do not come under EC review. The EC regulations have been highly successful in accomplishing their stated purpose, to ensure the compatibility of new development with existing resources. There has been recent concern whether the EC regulations protect 101 'the scenic quality of designated roads, specifically Route 250 West, as effectively asthe previous Scenic Highway regulations. A citizens' group has recommended developing specific EC guidelines to maximize protection of the unique characteristics of individual roads. The Open Space Plan previously recommended that corridor plans be prepared to guide development along designated entrance corridors. Corridor-specific plans have not been prepared, rather the adopted guidelines · require attention to the existing character of an entrance corridor in order to achieve unity and coherence. The existing character of designated entrance corridors varies widely, from urbanized Route 29 North to relatively undeveloped Route 250 West. At the same time, many corridors share similar characteristics. These differences and similarities can be addressed in more specific guidelines. In lieu of developing a separate corridor plan for every entrance corridor, one or two corridors could be analyzed by sections, such as village development, farmland, and urban commercial areas. Specific guidelines Could be developed for each typical section, and the resulting guidelines used as a model for corresponding sections in other entrance corridors. In this way, the current EC regulations could be used to further protect scenic, aesthetic and · historic characteristics of exceptional roads. These same guidelines could be used as design standards for roads which require visual protection, but which currently do not qualify as arterial entrance corridors. Such roads may be exceptionally scenic, such as Sugar Hollow Road, or visually prominent, such as Rio Road. The appearance of urbanizing corridors such as Route 29 North is a specific concern. Route 29 North serves as a major entrance and travel route through the community, provides access for high traffic generators such as highway-oriented commercial uses and industrial uses, as well as for expanding residential communities. These areas of intensive land use require a design vision to ensure that future development is compatible with the County's natural beauty. Guidelines developed for Route 29 North (setbacks, service roads, pedestrian access, landscaping, common signage) can be used as a model for other developing urban corridors in the County. Strategy: Use design standards to help maintain the integrity of all roadways in Albemarle County. Strategy: Identify specific roads as possessing exceptional scenic, aesthetic, and historic characteristics that are assets to the County and deserve protection. Further protect these exceptional roads through voluntary measures and land use policy decisions using design standards and guidelines. In addition to the designated. Virginia Byways, some roads previously identified for consideration are: Route 614 (Sugar Hollow Road), Route 692/712 (Plank Road), and Route 810 (Brown's Gap Turnpike). Strategy: Review the EC guidelines for effectiveness in protecting the integrity of exceptionally scenic EC road corridors, such as Route 250 West. Strategy: Analyze two Entrance Corridors (250 West and 29 North) by typical sections, such a village, farmland, and urban commercial Develop specific guidelines for each typical section, and use guidelines as a model for other Entrance Corridors, and to further protect exceptional EC roads. Strategy: Pursue additional EC designations as appropriate, or as road classifications change (Meadowcreek Parkway, Airport Road, Rio Road). Strategy: Pursue additional Virginia Byway designations for roads meeting State c)iterit~ 102 Scenic Designations: Streams OBJECTIVE: Protect the scenic quality of Albemarle's streams. Scenic stream designations include state-designated Virginia Scenic Rivers and locally-designated Scenic Streams. .The Scenic Rivers Act of 1970 provides for the identification, protection and preservation of rivers or sections of rivers that possess natural or pastoral beauty of high quality. Protection and management of the river rests with the local government, but all state and local agencies must consider recommendations of the Department of Conse~ation and Recreation regarding planning for the use and development of the scenic river and related land resources. The Act requires that an advisory board of local residents be appointed by the Governor for each designated scenic river to advise the director of the Department of Conservation and Recreation regarding plans and proposals, including federal or state projects which could alter the scenic river. A state designation does prohibit construction of a dam or other structure which impedes the natural flow. The following rivers are designated as Virginia Scenic Rivers: Moorman's River from the Charlottesville (Sugar Hollow) Reservoir to its junction with the Mechums River; Rivanna River from the Woolen Mill dam to the Fluvanna County line; and Rockfish River from the Nelson County line to the James River. The 1996 Virginia Outdoors Plan recommends that the James River should be evaluated for inclusion as a Scenic River. Local protection is provided by the County Scenic Streams overlay district. A scenic stream designation restricts construction, grading and cutting of trees within 15 feet of the stream, and restricts construction and excessive cutting within 65 feet of the stream. The County Scenic Streams program should be evaluated for effectiveness, and revised if necessary. The following stream is currently designated as a County scenic stream: Moorman's River from the bottom of the Charlottesville Water Supply dam at Sugar Hollow to its confluence with the Mechums River. Strategy: Review the effectiveness of County Scenic Streams regulations. Coordinate regulations with the Coordinated Water Resources Ordinance. Strategy: Using revised County Scenic Streams~ criteria (Appendix 5, Open Space and Critical Resources Plan), pursue local designation of qualifying streams, including designated Virginia Scenic Rivers. Strategy: Pursue Virginia Scenic River designations for rivers meeting state criterita Shenandoah National Park Related Lands Study A study was completed in 1993 by the University of Virginia and the Shenandoah National Park, which included an inventory of lands in Albemarle County with a direct ecological or land use relationship to the Shenandoah National Park. The purpose &the study was to identify the kinds of resource values that are important to the users, managers, and neighbors of the park. The study also identified alternative strategies, including both public and private initiatives, for conserving resources of mutual interest to the Park and the County. The County and the Shenandoah National Park have a mutual interest in protecting scenic views of and from the Blue Ridge Mountains and Shenandoah National Park. 103 Scenic resources inventoried included views from the Skyine Drive/Appalachian Trail; views from USRoute 250; and visual quality. ~, DESIGN STANDARDS It is important to address visual quality during the process of designing and placing roadways, bridges, buildings, structures, signs, lighting and parking areas in the landscape. The visual impact of new development in both the Development Areas and in the Rural Area can be improved if design standards are followed. Design standards found in this Plan are: Mountains Design Standards (p.54); Village Development/Design Guidelines (Land Use Plan p. 13); Land Use Standards (Land Use Plan pp.22-25); Location of Utilities (Land Use Plan p. 130); and General Design Standards for Roads (Land Use Plan p. 178). Also, the adopted design guidelines for Entrance Corridors provide more detailed standards. In addition, the following GENERAL STANDARDS should be used to protect scenic quality in the Rural Area and in Development Areas: 1. Maintain existing vegetation adjacent to roadwa~vs when wooded areas are developed. 2. Locate development in or near a wooded area, where it is less obtrusive than in an open area. 3. Adapt development to the topography rather than unnecessarily modifying the topography and natural setting to accommodate development. 4. Retain trees on hillsides and ridges so as not to alter the natural horizon and visual character of the area. 5. Locate structures at lower elevations which do not exceed the treeline of hillsides and ridges. 6. Incorporate significant landscape features, both natural and man-made, into new site designs. 7. Landscape with indigenous plant species. 8. Protect the settings of historic structures through setbacks and buffering. 9. Design public utility corridors to avoid open space resources and to fit the topography. Corridors should be shared by utilities when possible. Communications towers should follow adopted tower guidelines. 10. Maintain natural corridors along streams to protect the visual qualities of watercourses. 11. Avoid crossings of scenic streams by roads, utilities and the like. Where such crossings are necessary, particular care should be exercised to maintain visual character. 12. The County should take an active role in the design of Virginia Department of Transportation road improvements and bridges on scenic roads. 13. Limit the building mass and height to a scale that does not overpower the setting. 14. Connecting, grid-type street design may be preferable to cul-de-sacs. 104 OF ~'OTTSVlLLE ALBEMA COUNTY, SCENIC RESOURCES ,.,,m ~ ~ ENTRANCE CORRIDOR VIRGINIA BYWAY STATE SCENIC HIGHWAY nt~RBIIIllmSilM COUNTY SCENIC STREAM lllJlJlJllJ STATE SCENIC RIVER ~OR CiTY ~OUNDaRY {II VA.

It is intended that the completed Historic Preservation Plan will then be adopted as part of the Comprehensive Plan, probably as a freestanding document like the Open Space Plan.] This section provides a summary of the history of Albemarle County, a description of the existing surveys of Albemarle County's historic resources, and a listing of all properties recognized on the state or national registers. Albemarle's complete historic preservation program, including additional strategies, is described in detail in the Historic Preservation Plan. GOAL: Protect the County's historic and cultural resources. OBJECTIVE: Continue to identify and recognize the value of buildings, structures, landscapes, sites and districts which have historical, architectural, archaeological or cultural significance. OBJECTIVE: Pursue additional protection measures and incentives to preserve Albemarle's'historic and archaeological resources in order to foster pride in the County and maintain the County's character. Historic preservation is generally considered to be a component of rural conservation in areas such as Albemarle County, where an agrarian economy predominated during much of its history. The older surviving historic buildings and structures typically relate directly or indirectly to agricultural pursuits. Accordingly, a rural setting is an important part of the contribution by these historic resources to the County's heritage. Many historic resources are also located within the Development Areas. Within these areas, choices about growth and change should include the preservation of historic buildings and structures. Adaptive use may be a practical approach to preserving these important historic resources. History of Albemarle County Historic preservation is not just about architecture. The preservation and study of buildings and structures is an important component within the broader context of Albemarle County's cultural heritage and sense of community identity. The key ingredient of this broader context is the people of the County. Their "sense of community identity," also known as "sense of place," can be defined as "an awareness of simultaneous belonging to both a society and a place." It accrues slowly--not through grand pronouncements, but through small daily lessons, not only in our own lifetime, but from lifetimes across the ages. Our historic resources are, therefore, meaningful not in isolation, but in the context of people across the ages--in the stories of those who built them, lived in them, and used them. This context of people, their stories, and their buildings shapes the community's cultural heritage and contributes to a profound sense of continuity and belonging. The buildings which still exist are the only tangible evidence of this contextual continuity which today's County residents can directly experience by sight and touch, and which visually remind us that this community is a place different from all others. It is therefore important to protect a broad spectrum of historic resources, from large, impressive mansions to modest dwellings and structures, so that the sense of community continuity and belonging will be meaningful to all our citizens. Knowledge of Albemarle County's history is an important step toward gaining an appreciation of the contextual relationships which characterize our community. To provide a historical perspective for later sections, succeeding paragraphs of this section summarize a brief history of the County. 106 PREHISTORIC PERIOD (ca. 10,000 B.C,-A.D. 1607) People have lived in Albemarle County for more than 12,000 years. The first inhabitants were Native Americans, whose long history in the County is preserved in archeological sites which lie buried in the floodplains of rivers and streams and in the surrounding mountains and valleys. These archeological sites are highly variable, ranging from rare remains of the 12,000 year old hunting camps of the first inhabitants to the dense accumulations of pottery fragments which mark the former villages of the Monacan tribe. The 600 year period prior to the founding of a permanent European settlement at Jamestown in 1607 witnessed dramatic and relatively sudden cultural changes in the Native American population in the Albemarle County area. Among the recognizable changes were an increase in population, an increase in the size and permanence of villages, and the growth of an agricultural economy to augment traditional hunting and gathering. Additionally, the Monacans established burial mounds where they interred the remains of thousands of individuals. In the mid- 18th century, Thomas Jefferson investigated one such burial mound between the forks of the Rivanna, an exploration later noted as the first systematic archeological excavation conducted anywhere in North America. HISTORIC PERIOD European Settlement to Society (160%1750) European settlement of the Albemarle County area began in the late 1720s, when three land patents were successfully settled on land suitable for fanning along the Southwest Mountains and the James and Rivanna rivers. Over the next twenty years more settlers arrived, and in 1744 Gooehland County was divided and its western part became the new county of Albemarle. The initial County boundaries encompassed a far larger area than present-day Albemarle, e>~tending southward to the vicinity of Lynchburg. They included the current counties of Albemarle, Amherst, Appomattox, Buckingham, Fluvanna, and Nelson, as well as a portion of Campbell County. The county seat was established at Scott's Landing on the James River, about a mile west of today's Scottsville. The early settlers were a mixture of tobacco planters from the Tidewater region with Scots-Irish and German farmers moving east over the Blue Ridge Mountains from the Shenandoah Valley. The former tried to transplant the slave-mn tobacco plantation system to the southern and eastern parts of Albemarle, while the latter operated family-mn farm s raising cattle and grain in the northern and western areas. Colony to Nation (1750-1789) In 1761 the large area south of Albemarle's current boundary was split off, and that part of Louisa County which extended to the Blue Ridge was added to become the northern portion of the now much smaller Albemarle County. As a result, Scott's Landing was no longer a convenient location for the courthouse. The town of Charlottesville was therefore established in 1762 near the new geographic center of the County, adjacent to the Three Notch'd Road linking eastern Virginia to the Shenandoah Valley. Albemarle County's current boundaries were attained in 1777, when Fluvanna County was formed from the easternmost part of Albemarle. During the American Revolution, Albemarle was spared the effects of major military campaigns, although its citizens contributed both politically and in military service. By the close of the Revolutionary War, the County had been transformed from a frontier settlement to an established community. Its geographic and political boundaries had stabilized, its new county seat was developing, and it had Sect~ed trading and c6mmunication links with the rest of the new nation. Examples of resources from this period are Findowrie, Solitude, Everettsville Tavern, and the early parts of Castle Hill and Piedmont near Greenwood. Early National Period (1789-1830) By the end of the 18~ century, wheat had become the County's primary agricultural product, although tobacco was still widely planted, and the slave population continued to rise until 1850. Farms and plantations remained the primary economic factor, but small industry (tanneries, saw mills, and flour mills) had begun to grow. 107 'Internal improvements fostered the expansion of towns by making the Rivanna River more navigable and upgrading key roads into turnpikes. The University of Virginia admitted its first students in 1825, and the builders Thomas Jefferson recruited for its construction helped disseminate his ideas. The Jeffersonian architectural influence, initially evident throughout Central Virginia, has since spread to other parts of Virginia and the nation. Examples of resources from this period are Monticello, Redlands, Woodstock Hall, Carrsbrook, Brookhill on 'the South Fork Rivanna River, Plain Dealing, Tallwood, Sunny Bank, Morven, Malvern, Mountain Grove, D.S. Tavern, Black's Tavern, Merrie Mill, Cove Presbyterian Church, and Shadwell Canal locks and dam. Antebellum Period (1830-1860) Beef cattle production began to rise by the mid-nineteenth century, although grain and tobacco continued to dominate agricultural economics. Railroad construction in the late 1840s changed the County's culture and economics. Towns which had prospered when water was the primary means for moving goods began to decline, while new communities grew around railroad depots. As the terminus of the railroad to Orange County, and later through the Blue Ridge to the Shenandoah Valley, Charlottesville's progress was assured. 'Examples of resources from this period are Cliffside, Old Hall, Arrowhead, Pleasant Green, the Cedars, outbuildings at Cloverfields, Clover Hill Farm, and Kinloch, Scottsville canal warehouse, Piedmont Store, Grace Church, Mt. Ed Baptist Church, and the Blue Ridge Mountain tunnels. Civil War (1861-1865) The Civil War, like the Revolutionary War, brought few military encounters to Albemarle, although many sick and wounded soldiers were nursed here. Communities were not untouched by the war, however, since many of the County's husbands and sons in military service became casualties. During the last months of the war, Charlottesville was occupied by Union forces marching from the Shenandoah Valley toward Richmond. The town and the University were largely spared, but there was considerable economic destruction along the route of march. An example of a resource from this time period is the Batesville Methodist Church. Reconstruction and Growth (1865-1917) In the first two decades after the Civil War, fr6ed blacks were a majority of the population, and they became farm tenants, sharecroppers, or small tradesmen such as blacksmiths, cobblers, or carpenters. These freed slaves founded several rural black communities such as Bethel (now Proffit). By the close of the nineteenth century, outmigration of blacks to better opportunities in northern cities caused a population shift back to a white majority. Black communities and institutions persisted despite this population decline, however, providing historically significant examples of houses, churches, schools, and lodge halls which illustrate the African- American experience in Albemarle County during this period. Railroads continued their expansion, contributing to continued economic progress and the growth of villages around rail depots, but the advent of the automobile in the early twentieth century marked the beginning of decline for some rural villages. Farms were smaller, more numerous, and more diversified. Orchards, vineyards, and the raising of beef, dairy cattle, and sheep replaced large slave-operated wheat and tobacco farms. Some rural families began to move to Charlottesville, attracted by job opportunities and urban conveniences. By 1888, Charlottesville had grown sufficiently to incorporate as a city. Around the turn of the century, capitalists from outside the County began to buy old estates as part-time residences, renovating historic homes already there or building grand new ones. This preserved or created some of the County's finest architectural resources, and protected some of its rural landscape. Examples of resources from this period are Kirklea, Seven Oaks Farm, Cobham Park, the worker houses at Alberene Quarry, Esmont National Bank Building, Miller School, Green Teapot Hotel, Advance Mills truss 108 bridge, Nortonsville Store, Johnson's Store, Evergreen Baptist Church, Mt. Calvary Baptist Church, Dr. Kyger's house and office, Crozet Cold Storage, Crozet Hotel/Hardware, and the original Crozet Railroad Depot. World War I to the present (1917-1997) Rail service was frequent and reliable in the early twentieth century, but all-weather roads maintained by the state did not appear until 1922. By the early 1930s the state had established a network of roads in the County. This coincided with the beginnings of a tourist component in the area's economy, aided by the opening of Monticello to the public in 1924. Better roads and more families with automobiles spawned housing subdivisions on farms that once surrounded the urban core of Charlottesville. This phenomenon began early in this century and has continued since then, with an upsurge after World War II and again in the 1970s. The number of farms in the County peaked at 3,379 in 1924, and as recently as 1940 over half the population was involved in some form of agriculture. By 1970, however, only 847 of the County's labor force of 14,208 were full-time agricultural workers. Agriculture, the traditional economic base, remains a significant land use, but has been replaced as the principal employer by a combination of education, tourism, and small manufacturing and service industries. Examples of resources from this period are Tiverton, Blue Ridge Farm, Rose Hill, Casa Maria, Farmington Subdivision, Sunset Lodge, Town and Country Motel, Stony Point (High) School, and Cobham Park gardens. Surveys and Historic Resources In both numbers and quality, Albemarle County's inventory of historic buildings and structures still standing in 1998 justifies a strong effort to protect these non-renewable resources, and the first step in any preservation program is a survey of existing historic resources. Surveys, either previously developed, new, or updated, are the standard tool for demonstrating that buildings and structures to be protected have "important historical, architectural, archaeological or cultural interest." (The quoted phrase is the criteria specified in the Code of Virginia which enables the County to protect its historic resources.) Albemarle County benefits from a substantial base of completed surveys, on which it can build its current historic preservation efforts. EXISTING HISTORIC RESOURCES SURVEYS The Virginia Department of Historic Resources (VDHR) records for Albemarle County identify more than 2000 buildings and structures and 400 archaeological sites which have been surveyed as potential historic resources. The records also indicate that only four other counties in the state have had more than one thousand historic buildings and structures surveyed. The vast majority of these resources were surveyed between 1979 and 1983 by architectural historians for the VDHR (then the Division of Historic Landmarks), who conducted a comprehensive, reconnaissance-level architectural survey of approximately 1600 resources in Albemarle County. Augmenting these VDHR efforts, students at the University of Virginia School of Architecture have conducted numerous architectural surveys and building studies from the mid-1970s to the present. These surveys are available at the Fiske Kimball Fine Arts Library, School of Architecture. A book on the architectural history of Albemarle County, by University of Virginia Professor K. Edward Lay, is projected to be published in early 1999. This book is based on twenty-five years of research and, together with its accompanying searchable CD- ROM, will document over 2300 historic resources in the County. In January, 1992, a nomination report was completed for the Southwest Mountains Rural Historic District, and the district was listed on the National Register of Historic Places. This effort was initiated by the Piedmont Environmental Council, with the final report prepared by Land and Community Associates. Contributing resources surveyed for the report include approximately 109 domestic complexes, 11 churches, 16 commercial buildings, and 2 railroad depots on 31,975 acres. A copy of the report is available at the Department of Planning and Community Development. 109 The VDHR and Albemarle County cosponsored two study efforts which were completed by consultants in 1995. In May, 1995, Garrow and Associates, Inc., prepared a report called From the Monacans to Monticello and Beyonck Prehistoric and Historic Contexts for Albemarle County, Virginia, which developed prehistoric and historic contexts to synthesize the primary data on the prehistory, history, archaeology and architecture of the County. This document builds on the data base created by earlier surveys, including those of VDHR, Lay and his associates and students, and the U.S. 29 Corridor Study. It did not conduct any new surveys. A copy of the report is available at the Department of Planning and Community Development. In October, 1995, Dames & Moore prepared a report c011ed Historic Architectural Survey of Albemarle County Villages, which included survey results and evaluations of 200 resources in twelve villages. Historic context reports were prepared for each village. The principal finding of the survey was that all or portions of six villages: Advance Mills, Batesville, Crozet, Proffit, White Hall and Yancey's Mill, are potentially eligible for listing as historic districts on the National Register of Historic Places and the Virginia Landmarks Register. A large area surrounding Greenwood was also recommended for a National Register Rural Historic District. ARCHAEOLOGICAL SURVEYS Current knowledge of archaeology in Albemarle County derives primarily from the efforts of C.G. Holland and Jeffrey Hantman. As of October, 1984, 139 prehistoric and historic archaeological sites in Albemarle were on file at the Virginia Research Center for Archaeology. Most of these were recorded by Dr. C.G. Holland, who conducted a survey published in 1955. In 1985, Jeffrey Hantman prepared The Archaeology of Albemarle County, which projected the presence of about 3,000 archeological sites within the County Growth Areas based. on sample surveys. Since 1985, archaeological surveys conducted as part of the environmental impact study for the Route 29 Bypass altematives recorded many new sites. The completed studies are available at the Department of Planning and Community Development. The cumulative survey results on file for Albemarle County at VDHR currently identify more than 400 archaeological sites. This is considered a small sample of the total number of County archaeological sites which exist either on or below its surface, since there has been no comprehensive archaeological survey of the entire County. HISTORIC REGISTER LISTINGS As noted in the 1995 Garrow Associates report: "...Albemarle County has one of the best collections of domestic architecture in Virginia, ranging in age from small mid-eighteenth century vernacular dwellings to impressive, early twentieth century, Classical Revival mansions." The roster of County properties, primarily the oldest and grandest, already listed on the Virginia Landmarks (State Register) and on the National Register of Historic Places (National Register) is impressive. At the end of 1998, there were 60 individual sites and five districts on the State Register. Four districts and all but three of the individual sites were also on the National Register. Four National Register properties--Monticello, the Rotunda and Lawn at the University of Virginia, a separate historic district at the University, and Fiske Kimball's residence, Shack Mountain--have earned designation as National Historic Landmarks, the highest national recognition category for historic resources. (See map of registered historic properties) Monticello and the RotundaYLawn also appear on the World Heritage List, an international honor accorded only six other cultural resources and eight natural resource sites in the United States. Consequently, these two Albemarle County sites rank with the Statue of Liberty, Independence Hall in Philadelphia, the Palace of Versailles, and the Taj Mahal in terms of contribution to the heritage of the. country in which they are located. The following table lists properties currently on the Virginia Landmarks Register and the National Register of Historic Places. World Heritage List properties are indicated by an asterisk. This list of registered properties shows the tax map and parcel number, the name of the individual property or district, and the date the property or district was designated for listing on the applicable register. The last column indicates the date a historic easement was placed, on the property, and the acreage, if applicable. If there is no date shown in the National Register column, the property is either: (1) ineligible, generally due to relocation from its original site; or (2) the 110 property is a recent Virginia Landmark Register entry, and the National Register process may not yet be completed. Strategy: Seek available state and federal grant funds to conduct an archaeological survey of designated historic period sites and/or districts to evaluate their archaeological resource potential. Strategy: Compile and maintain a current and comprehensive information base for Albemarle County's historic resources. Strategy: Include sites which are potentially eligible for designation as a Virginia Historic Landmark in a County resource map of historic landmarks. Strategy: Initiate studies similar to the Southwest Mountains historic district study in other areas ofthe County which include numerous register properties and potentially eligible properties, possibly along historic corridors such as the Road to Secretary's Mill (Rt. 20 South - Rt. 717) and the Staunton and James River turnpike (Rt. 692 - Rt 712 - R~ 20 South). Strategy: Promote voluntary measures and techniques such as historic and conservation easements which serve to protect historic resources and their settings. Strategy: Seek citizen participation in County studies and other preservation activities. Strategy: Adopt a Historic Overlay District ordinance to recognize and protect historic and archaeological resources, including individual sites and districts, on the local leve£ Strategy: Defining the Monticello viewshed as all property visible from the Monticello mountaintop, protect Monticello's setting and viewshed as follows: · Notify the TJMF ofproposed developments in the designated viewshed area so that they are afforded opportunity to provide comment during the approval process; · Strongly encourage the developer to consult with the TJMF about the visual impact of the project; · Strictly enforce existing regulations; · Carefully review by-right development plans with suggestions for voluntary protection measures; · Require protection measures as appropriate on discretionary land use proposals, and · Consider the impact ofproposed land use regulations and decisions on Monticello's viewshet~ Strategy: Promote preservation by making available information regarding tax incentives and designation procedures. Strategy: Create a notification program to educate owners of historic properties, especially new owners, about the significance of their property, and to suggest ways they might protect those resources. Encourage and assist owners of potentially eligible sites to pursue Virginia Landmarks and National Register designations and historic easements. 111 ount Fair Blue Fa~n Mill~- School of AIb~ Hall ?ave'tn COVESVIU.E, Cooke's !

It is referred to as the Open Space Plan, and is contained in an attached, separate document along with the Concept Map, and the Development Area Maps (formerly called Growth Area Maps). This Comprehensive Plan update will revise the follOwing provisions of the 1992' OPen Space Plan: Comprehensive Plan goals, objectives and strategies for: sustainability; natural, scenic, and historic resources; agricultural and forestry resources; and open space planning. Many of the goals, objectives and strategies of this Comprehensive Plan have been revised from those which are referenced in the Open Space Plan. The list of Mountains identified in the Open Space Plan by contour elevation and the corresponding Mountains as delineated on the Concept Map. The revised list is included with the section on Mountains on page --. Open Space Plan Summary OBJECTIVE: Protect the County's open space for its environmental, aesthetic, cultural, agricultural/f orestal and recreational value. The purpose of the Open Space Plan is to guide efforts to plan for and protect open space in the County in a comprehensive and integrated fashion. Open space is important to protect and utilize for its environmental, aesthetic, cultural, agricultural/forestal, and recreational value. Open space can be protected using appropriate voluntary, cooperative, public and private efforts, as well as regulatory measures. The Open Space Plan consolidates all currently available information regarding natural, scenic, historic, and agricultural/forestal resources in the County in order to identify the most important areas to protect as open space. It identifies four major systems of open space which extend across the boundaries of the Rural Area and the Development Areas: Major Stream Valleys, Important Farmlands and Forests, Mountains, and Cultural Resources. This information is shown on maps at two scales: The Open Space Concept Map is a reference map of resources for the entire County. It is intended to serve two functions: to guide open space decision-making in the County as a whole, by identifying major open space systems which are the most important open space lands to protect; and to provide a starting point for the ongoing identification and protec.tion of Rural Area open space resources. The Development Areas Open Spac~ Maps are specific maps which delineate important open space within the designated Development Areas. They are to be used as the primary guide for the protection and acquisition of open space within the Urban Area Neighborhoods, the Communities, and Villages. The Plan also proposes additional study of Rural Area resources, called a Critical Resource Inventory, which would supplement the information shown on the Concept Map. The inventory would represent the rural equivalent of the detailed Development Area Maps. Strategy: Use the Open Space Maps to guide open space planning decisions and to identify and protect significant resources as development occurs in theDevelopment Areas and Rural Aret~ (See Open Space Plan Implementation Section for procedure.) 117 Critical Resource Inventory OBJECTIVE: Continue to plan for open space and significant resource protection by completing the Critical Resource Inventory. An inventory of significant natural, scenic, and hiStOric resources, predominantly in the Rural Area, is needed in order to complete the Open Space Plan. A Critical ResOUrce Inventory would supplement the information on significant resources currently available for bOth the Rural Area and the Development Areas. Significant resources which require further study, identification and mapping include: Biological resources; ' Historic and archaeological sites; Agricultural and forestry lands; and Scenic roads and streams. Biological resources include plant and animal communitieS and their habitatS~ This categorY alS° maY include natural areas, old growth forests, and rare, threatened, and endangered species of plants and animals. An inventory of biological resources is discussed on page -. Historic resources surveys and inventory are discussed on page -. Archaeological sites haVe not Yet been comprehensively studied and located. Agricultural and forestry resources are discussed on page -. More specific mapping of agricultural.and forestry resources, and historic and archaeological resources may be accomplished when a Geographic Information System becomes available. Scenic roads and streams need to be further studied and identified. They are discussed on page -. A Geographic Information System (GIS) would facilitate identification of resources on a County-wide basis. A GIS could be used to generate overlay maps and allow a more accurate assesssment of detailed information such as critical slopes and soils, and parcel-based information, such as agricultural/forestal districts. Following completion of the inventory, the Concept Map and recommendations of the Comprehensive Plan should be amended to reflect the additional information. Strategy: Implement a geographic information system (GIS) to facilitate identification of significant resources on a County-wide basis, and to generate overlay maps which would allow amore accurate assessment of these resources. Easement Program and Public Lands OBJECTIVE: Promote protection through easement, purchase or donation of fee simple or development rights, those important open space lands which cannot be adequately protected through regulation. OBJECTIVE: Identify open space areas suitable for public access or recreation. Promote the use of significant natural or man-made corridors as linear parks to provide a unique recreational opportunity. Voluntary donation of easements is an excellent method of open space and natural resource protection. The landowner who donates an easement permanently protects the land, while retaining ownership and enjoyment of the property. In many cases an easement may provide estate planning benefits. There is no public access to easement properties. The public benefits because areas with important open space resources are permanently protected without additional regulation, and without cost to the County. Any loss in taxes is offset by the reduced need for services. Purchase of development rights (PDR) is similar in effect to a conservation easement except the development 118 rights are purchased from willing landowners by a county or other entitiy. Resources are identified for protection based on the Comprehensive Plan. The success ofa PDR program is limited by available funds, which may be obtained from various sources. The landowner retains ownership, and the property is protected in perpetuity. The County's appointed PDR Committee has made recommendations regarding implemntation of a PDR program. In some cases, fee simple purchase is a preferred alternative, when public ownership and access is warranted, as in a public park. The County currently owns in fee simple the Preddy Creek tract which could be opened for public access. The Preddy Creek tract should be evaluated as a potential natural area for public enjoyment of natural history and pa.ssive recreation. (Also see Parks and Recreation Recommendation, page 148 of Land Use Plan.) Strategy: Actively encourage and facilitate the donation of voluntary easements consistent with the Open Space Plan. Easements should be donated to the Virginia Outdoors Foundation (VOF). If not acceptable to I/OF, then easements should be donated to the Recreational Facilities Authority. Strategy: Utilizing the Recreational Facilities Authority, provide information to the public regarding the benefits and means of protecting open space through easements and other voluntary techniques. Strategy: Pursue a purchase of development rights (PDR) program as recommended by the PDR committee. Strategy: Pursue enabling legislation to permit a density transfer program or Transfer of Development Rights (TDR) progratr~ Strategy: Utilizing the Recreational Facilities Authority develop a County acquisition progran~ The Authority should investigate methods of acquisition and methods of funding acquisitions and long term management costs. Pursue legislation as necessary to implement open space funding measures. (Such as a transfer tax or impact fees.) Strategy: Use the Composite Maps to guide acquisition in the Development Areas. When the Critical Resource Inventory is completed, expand the program to include important Rural Area open space. Strategy: Coordinate public and private acquisition programs for open space lands to avoid duplication of efforts. Strategy: Due to the regional nature of the proposed greenway corridors and the regional use of certain existing parks, evaluate a regional approach to parks/open space managemen~ Strategy: Further study the following areas for open space~recreation potential: Urban Area Potential park: In Neighborhoods 4 and 5, possibly along Biscuit Run or opposite Azalea Park; Hollymead Potential park: Area northeast of the Route 29~Route 643 intersection; Crozet Potential park: Area northwest of the proposed Lickinghole Creek basin; Area along Powell's Creek and adjacent to Orchard Acres; Earlysville Potential park: 119 Area within Earlysville Forest designated for recreation. Rural Area Potential natural area for passive recreation: Preddy Creek tract 120 Urban Open Spaces OBJECTIVE: Recognize the value of urban open spaces (including among others: greenways, greens, squares, courts, plazas, urban parks and playgrounds, street medians, and tree lawns between street and sidewalk) as a structuring element in emerging urban areas, and as a part of a larger network of urban open space which may be linked to the rural open space syster~ There is a fundamental difference in the value and character of open space in urban and rural situations. In the Rural Area, the County is often seeking to conserve large systems of land of particular value (such as agricultural and forestry lands) or to preserve areas of significant resources (mountain ridges, stream valleys, wildlife habitat.) WhereaS, in urban areaS some Preservation of natural areas (such aS stream valleys) occurs, but more often, open spaces are designed and created. Their value to the community is determined by their shape, configuration, and relationship to buildings and other built forms, as well as their natural attributes. Urban open spaces will become more important aS the County's Development Areas become denser and as additional urban areas are developed. The Open Space Plan's Development Area Maps delineate the resource areas which should be consistently maintained for open space as development occurs. In addition, specifically designed open spaces should be incorporated as amenities into urban developments to offset the higher densities. In evaluating higher density proposals, the County will consider how they relate to existing open space systems, and how they create new open spaces. In his book, Open Spaces, August Heckscher states: "Each city [urban area] is a place of its own, its uniqueness determined in large measure by patterns created by the alternation of stmcure and void, of buildings and spaces between. The larger green spaces, parks and parkways, riverbanks and waterfronts, give to a city the coherence that allows the urban dweller to have a feeling for the whole." "Such green spaces may be viewed as the city's skeleton. They are the underlying structure from which depend neighborhoods, institutional complexes, and business centers. A person who knows his parks can tell where he lives...and because parks are so often the product of basic topography, he should not be ignorant of how his city is related to land, to river, to sea." Greenways are discussed in detail, but all types of urban open spaces are recognized for their importance in providing structure to urban design, and contributing to the quality of life of all County residents. Strategy: Evaluate all Development Area proposals for their contribution to the urban open space networlc 121 Greenways OBJECTIVE: Establish a County-wide network of greenway trails for conservation, recreation, transportation and education throughout Albemarle County, and linked to trails in the City of Charlottesville. Introduction This section of the Comprehensive Plan is intended to serve as a guide for the establishment of a County-wide network of greenways. Recommended in this section'is the construction of an approximately 52 linear miles greenway.network along streams and rivers, along with proposed actions to implement and maintain this system. The purpose of the system is to link people to the area's natural, recreational, cultural and commercial resources. The provision ofgreenways are recommended in the Land Use Plan Section of this Comprehensive Plan, the Open Space and Critical Resources Plan and the completed Neighborhood Plans (Neighborhood Three [Pantops] Plan and the Crozet Community Study). It is recognized that this is an ambitious plan and that development will be a very long term project (beyond 50 years). It is also recognized that full development of this plan may never be realized due to financial constraints, topography, or a property owner's unwillingness to locate a trail on his 'or her property. The trail locations proposed in this section are conceptual in nature. Ultimate location of a trail may not be along a river or stream corridor due to steep slopes, soil type, sensitive resources, environmental resources or other community concerns. Also, there may be areas identified in this section for a greenway trail, that for various reasons do not lend- themselves for trail construction. It is expected that certain trail segments within the total greenway network will be established as high priority prujects and resources will be initially target for the construction of these trail segments. It is expected that large portions of the greenway system will be built on an opportunistic basis by various civic groups and/or member of the development community. Prior to construction of any trail segment, a detail plan with the specific trail location and type will be formulated to allow community input and comments. The construction ofa greenway system is a huge undertaking that inVolves many different groups and individuals, therefore, it is important to generate broad community support for the plan, prioritize areas for development, and utilize creative and innovative methods of funding and developing the greenways. The complete Greenways Plan is attached as an appendix to this Comprehensive Plan. What are Greenways? Greenways are areas of open space, usually linear in nature. They are often located along streams/rivers, utility easements, abandoned railroads and along roadways. The proposed Albemarle County greenway system is located primarily along streams and rivers; however, there are some sections proposed to be located away from water- courses. The Albemarle County greenway system has four major functions: Protect important and/or sensitive resources - Greenways corridors can function to preserve and maintain stream side forests arid buffer areas which are highly productive and diverse systems which provide many important benefits. The quality of water can be maintained or improved by forested buffer strips along streams and rivers. The trees and shrubs filter and trap sediments and absorb pollutants from overland runoff and from the shallow ground water zone. The major pollutants include herbicides and the nutrients nitrogen and phosphorus. Although these nutrients are essential for the growth and development of all plants, an overabundance of either one may upset the delicate balance of the plant-nutrient-water relationship and actually become toxic to plants and animals. The stream side forest and buffer areas are not only vital in improving water quality, but they generally house a great variety of plants and habitats, which is the main reason why they produce a great diversity 122 of wildlife. Trees and shrubs are important for nesting birds and other animals and produce an abundance of food for wildlife. Contiguous forest areas also provide protective pathways for safe movement or migration of animals. Stream side forest and buffer areas make streams and rivers suitable for many kinds of fish and other aquatic creatures. Tree roots help stabilize the stream bank and provide cover for fish, crayfish and aquatic insects. Plant materials that fall into the stream/river are a vital food source for many organisms. Bacteria, fungi, aquatic insects larvae, crayfish and other invertebrates break down this plant material into small particles. This very fine plant material known as detritus, is used as food by many small aquatic animals such as minnows and insect larvae, which are major food source for the larger game fish. Also greenways serve as overflow areas to absorb storm runoff and prevent flood damage; recharge aquifers; and maintain settings for natural and historic features, particularly historic and prehistoric archeological sites. Provide recreational and educational opportunities - Greenways provide recreational opportunities such as hiking, bicycling, fishing, picnicking and Canoeing. Also, greenways can function as "living classrooms" for nature studies of life histories and behavior of plants, animals and fish. These areas also have a great variety of birds making them favorite sites for bird watchers. Greenways increase the public's awareness of the environment. Provide an alternative transportation system - Greenways can function to provide pedestrian and in some cases~ bicycle connections to natural, recreational, commercial and cultural resources. Portions of the planned greenway system in the County will be located near a large segment of the County's population, allowing citizens to travel by foot and bicycle instead of by the automobile to parks, activity centers and commercial areas. Greenways will provide important connections between County neighborhoods and provide an excellent opportunity to promote public access to rivers and streams and improve the overall environment of the neighborhood. Greenways can help build Albemarle County's sustainable future by connecting people and land in a manner that helps re-establish the close connections between the environment, economy and society. Provide an economic benefit- Greenways can promote the areas economy while maintaining environmental assets directly in terms of eeo-tourism, and indirectly, in terms of increased property values. Commercial properties, especially restaurants can consider greenway/river oriented developmem. Design could encourage trail users to come-up to the shopping/commercial area and encourage shoppers to visit the river. General Principles 1. Establish a greenway system in Albemarle County that provides: · Protection of river corridor vegetation, water quality and the viability of wildlife habitats; · Recreational opportunities such as hiking, bicycling and fishing close to residential areas; · An alternative transportation link of the Coun.ty's and City's communities, parks, activity centers, schools, and commercial and office areas, thus reducing traffic congestion; and · Educational opportunities such as nature hikes, species and plant identification, and interpretation of historic, architectural and natural resources. Coordinate adjacent land development with consideration of the greenway, so that existing and future development will be integrated and harmonious with the greenwaysystem. Integrate existing off-river/stream trails into the greenway system. Encourage public involvement in the planning and development of the greenway system. 123 o Provide a cost-efficient trail system while meeting the principles oUtlined. Provide long-term-funding, maintenance, and administration for the implementation of the greenway system through a public-private partnership. 4. Develop community pride in the greenway system by increasing people's aWareness and appreciation of the greenway system through promotions and special events. Existing Greenway Facilities Currently, the only section of greenway in the County is a 2,700 foot section which is located between Elks Drive and the Rivanna River, from Route 250 East north to Darden Towe Park. Currently, minimal improvements have been made to this section of greenway. However, the County has received an ISTEA grant to provide major improvements to this section. Connecting to this County segment, there is a 1.32 mile greenway with a 10 foot' pedestrian/bicycle crushed stone trail located in the City south of Route 250 East along the Rivanna River. Dedication, or reservation for future dedication, of land for the construction of a future greenway trail has been made at the following locatiOnSi 1) Riverrun; 2) Glenmore; 3) Rivanna ReservOir at the end of Woodbum Road; 4) Rivanna Reservoir north and east of Hydraulic Road; 5) Moores Creek at Avon Street; and 6) Biscuit Run adjacent to Foxcroft. Greenway Advisory Committee A Greenway Advisory Committee should work with the Albemarle County Planning and Community Development Department and Parks and Recreation Department, and in cooperation with 'the City of Charlottesville and Rivanna Trails Foundation, to oversee and coordinate greenway implementation and maintenance. Implementing and maintaining a greenway system will require a public/private partnership which will involve many different groups and agencies. An oversight entity such as this advisory committee is desired to facilitate communications among the agencies, organizations and citizens groups involved to ensure that actions are coordinated. Therefore, it is recommended that a new organization tentatively called the Greenway Advisory Committee be created. Committee membership should consist of representatives from the development community, landowners, environmental community, civic groups, historic preservation community, naturalists and business community. Also, a person(s) with a biological background that understand such areas as botany, ornithology, mammals, etc. should be represented on the committee. The proposed responsibilities of this Committee may include: · Prioritize the various greenway projects. · Determine methods to promote and fund the greenway system. · Review trail plans to ensure that they are designed in a manner that adheres to agreed upon locations and standards. · Serve as advisory to the development process as necessary, and suggest methods in which a site can connect or be integrated into the greenway system. · Coordinate efforts of County Government agencies, private organizations, land owners and developers on matters involving the greenway system. · Propose recommendations to the County such as amendments to current zoning and subdivision regulations to facilitate implementation. · Refer landowners to appropriate land trusts; be pro-active in acquiring right-of-way/donation of land for greenways. · Work with the community and allow for citizen's input on trail related issues. · Arrange and coordinate operation and maintenance of the greenway system with volunteers and cooperating organizations. Strategy: Establish a Greenway Advisory Committee to assist the County in designing, implementing, promoting, and maintaining a greenway systent Strategy: Develop guidelines to identify appropriate greenway trail types and locations, design features for the various greenways, trail access points and trail facilities. 124 Strategy: Explore biking, jogging and pedestrian alternatives for railroad rights-of-way if any line is abandoned. Of particular interest are the sections from the Urban Area to Crozet and the Blue Ridge Mountains, and from the Urban Area to Shadweli along the Rivanna River. Strategy: Explore a pedestrian trail system along existing public roads and trails in Mountain areas. Greenway System Network The following areas below have been identified by the County as the general location for the greenway network along river and streams. These areas should be viewed as providing the main components of an overall greenway system. The maps in the Greenways Plan in the Appendix showing the location and type of trails are intended to be conceptual in nature and do not address details. Instead, these maps are intended to provide a framework for the implementation of the greenway system, and are not intended to preclude future opportunities for greenways not shown here. It is assumed that exact locations of trails will be determined in cooperation with communities and property owners of the area. URBAN AREA (NEIGHBORHOODS 1-7) AND RIVANNA VILLAGE - Rivanna River from the Ivy Creek Natural Area to Rivanna Village/Milton Airport. - Moores Creek and tributary from the Rivanna River to Ragged Mountain ReserVoir. Biscuit Run from Moores Creek to the southern portion of the Neighborhood 4 & 5 boundary. Meadow Creek from the Rivanna River to Brookmill Subdivision (Portions of this trail are in the City). HOLLYMEAD/PINEY 'MOUNTAIN Powell Creek and tributary stream from the South Fork Rivanna River to the Forest Lakes/Jefferson Village area. Jacobs Run and the North Fork Rivanna River from Chris Greene Lake to the eastern boundary of the Hollymead Development Area. CROZET Powells Creek from Jarmans Gap Road/Orchard Acres to Crozet Avenue. Lickinghole Creek from the Lickinghole Creek sedimentation basin to Brookwood subdivision. Slabtown Branch from Crozet Avenue to the Brownsville/Henley School compleX. Parrot Branch from the Crozet Elementary School to the Beaver Creek Reservoir. RURAL AREA - Rivanna River from the eastern portion of the Rivanna Village to Fluvanna County. - James River from Fluvanna County to Nelson County. - Unnamed tributary of Moores Creek from the Charlottesville Reservoir to Reservoir Road. Strategy: Utilize the Comprehensive Plan greenway maps (in the Appendix) as a conceptual plan for implementing the greenway systena Greenway Trail Implementation The process of turning a plan for the greenway system into a reality is a complex but exciting challenge that will require a cooperative effort involving many different people and organizations. While the total land area of the proposed greenway is relatively small, its benefits will be widely felt. It is unlikely that a single entity such as the Albemarle County Government can or will have the means to acquire or manage the extensive system proposed in this section. Therefore, it is recommended that the network of 125 greenways be owned and managed through a partnership effort. The system should be established piece by piece, by a number of entities using various methods. The Greenway Advisory Committee will coordinate the activities of the partners in implementing the greenway system. Possible partners include the Rivanna Trails FOundation, developers, landowners,citizen groups, non-profit organizations,State agencies, and other localities including the City of Charlottesville. Recommendation: · Work with private and government agencies at the local, state, regional and national levels to implement a greenway system in Albemarle County. The following proposed actions should be considered by the County to implement the Greenway Plan: PRIORITIZE GREENWAY SEGMENTS The Greenways Advisory Committee should initially select two greenway segments of one to three miles long as 'high priority for trail construction within a 5-10 year time frame. This action is proposed in order to bring recognition to the greenway section of the Comprehensive Plan and to launch the greenway implementation process. The two greenway trail segments selected should be easily accessible and relatively easy to implement. Securing the necessary funds for the greenway construction and maintenance should become a cooperative effort between the County, the Greenway Advisory Committee and the greenway partners. Other trail segments identified should be built during this initial phase of implementation on an opportunistic basis. Recommendation: · The Greenways Advisory Committee should propose two pilot greenways. The greenway segments selected should be easily accessible and relatively easy to implement. INCORPORATION OF THE GREENWAY PLAN INTO THE DEVELOPMENT PROCESS During the development process, the County Planning Department will identify areas proposed for trail locations. The areas identified will be the highest priority in open space dedication, and the County will seek, through dedication, donation or open space easement, the preservation of these corridors and the possible development. of trails as identified in this section. Also, new and existing residential and nonresidential developments should consider providing internal trails that link their development to the greenway. Developers may increase the marketability of their developments and provide amenities by contributing to' the greenway system. Protected scenic views, open space and trails near or adjacent to residential or nonresidential developments are valuable amenities and economic studies indicate that such amenities increase the value of the site. Recommendation: · Encourage developers to contribute to the greenway network by dedicating land, donating easements or funds, or constructing a portion of the greenway trail. INDIVIDUAL LANDOWNERS Public greenway trails may have an impact on a landowner's privacy. Some people fear that a greenway trail may bring litter, vandalism, and other crimes, believing that security measures may be needed to protect them against these problems. On the other hand, many people who live along greenways elsewhere, speak enthusiastically .about the. benefits of their trail: they enjoy the nearby recreation, protection of trees and open space, and resulting increase m property values. Crime has not been a major problem on trails in other parts of the country. When 126 a trail receives regular use, the presence of people discourages crimes. Recommendations: Encourage individual landowners whose land, or parts thereof, could be part of the greenway network to donate land or easements. · Support the establishment of methods to address safety and maintenance concerns of adjacent property owners. METHODS OF OBTAINING LAND In most cases, outright pumhase of land by the County or a private organization may be the best way to establish a greenway; however, there are other methods of obtaining land needed for the greenway system such private donations and voluntary conservation or public access easements. It is not the County's intent to utilize the right of eminent domain to acquire land for the greenway system. SOURCES OF GREENWAY FUNDING The County. should explOre sources of financing available from organizations who support and encourage greenway development in Virginia. Recommendations: · Utilize the Greenway Advisory Committee to solicit private donations of land for the greenway system. · Continue annual funding in the County's Capital Improvement Program to be used for land acquisition and development of the greenway system. · Attempt to obtain private, federal and State funds for the construction of the greenway system. · Attempt to initiate a fund raiser campiagn for the implentaion of the greenway system. MAINTENANCE Maintenance is one need of the greenway trail that is often overlooked. Administrative overhead can be reduced if portions of the greenway can be maintained by private organizations involved with the greenway system. The trail must be maintained on a regular basis. The issues that are most likely to cause concerns for adjacent residents are maintenance related such as-trash, overgrown weeds, fallen limbs or trees, and insufficient or poorly maintained screening that buffers the homes from the trail. Once a trail is established a regular maintenance schedule should be put in place. In addition, funds should be reserved for major maintenance problems that may arise from storm and/or flood damage. Neighborhood groups, church groups, and civic groups such as scout troops, garden clubs and Rotary Clubs, may wish to participate in an "Adopt-a-Greenway" program to maintain a section of the greenway network. As mentioned earlier, it is proposed that the Greenway Advisory Committee would publicize and build citizens support for greenways, and to coordinate citizen volunteer programs to assist with maintenance. Recommendations: · The County's Parks and Recreation Department will be primarily responsible for maintaining the greenway system. · Utilize the proposed Greenway Advisory Committee as an outreach group to'build community support, and 127 coordinate volunteer programs to maintain segments of the greenway system. PUBLIC AWARENESS Local awareness and interest in the development of a greenway system is critical for success. Promotion and marketing are key ingredients of a successful greenway system. Often when a trail project is promoted people assume that it will be completed in a short period of time. It is imperative that people are aware the greenway system is a long term project. It is also essential to maintain contact with local interest groups and keep them appraised of the project's status in order to cultivate support. Encourage citizen participation in the development of the Greenway Plans to give the community a "stake" in the success of the greenway system. Increase community awareness of the existing greenway system and future planned segments by providing brochure which include maps, length 'of trails, photographs, directions, park logos, etc. Have regular events on the trail such as nature walks, bird-watching, trail/river clean-up days, photo competitions, walk-a-thon, etc. Recommendations: · Encourage public involvement in the planning and development of the greenway system. · Inform and educate the public about opportunities generated by the greenway system. · Utilize the Greenway Advisory Committee to promote the greenway system. 128 APPENDIX COunty of Albemarle Proposed Mounta Where has Nature spread so rich a mantle under.~thg.~.eye? Mountains, forests, rocks, rivers. With what majesty do we there ride above the storms! workhouse of nature, to see her clouds, hail, snow, rain, thunder, all fabricated at our feet! And the glorious Sun, when rising as if out of a distant, water, just gilding the tops of the mountains, and giving life to all nature. --Thomas-Jefferson on Albe~rle,.s_ ,moun~igs ' FINAL REPORT Mountain Protection Com~i~g ~: August 1, 1996 MOUNTAIN PROTECTION coMMiTTE The Mountain Protection Committee consisting of 12 citizens appointed by the Board of Supervisors, met regularly from June, 1995 through July, 1996. The Committee reviewed existing County ordinances and regulations to assess the degree to which these public values are adequately protected at present. The County attorney as well as the Piedmont Environmental Council's staff attorney and Page Gilliam, a member of the Mountain Protection Committee and an attorney, reviewed the constitutional issue of taking without just compensation and Virginia legislative authority for local mountain protection. Other presentations were made by Natural Resource Conservation Service, Virginia Department of Forestry, County Department of Planning and Community Development, Department of Zoning, Building Inspections Department, the Water Resource Manager, and the County Design Planner. A member of the University of Virginia's Department of Astronomy gave a presentation and conducted a field trip on outdoor lighting and dark night sky as a natural resource. ,The Committee identified resources present in the mountainous areas Of Albemarle County that it is in the public interest to protect: · public safety · soil · water quality and quantity · forest and agricultural resources · plant and animal habitat · scenic resources and their economic impact · dark sky · tourism The Committee reviewed ordinances pertaining to mountain protection from other localities in Virginia. The Clarke County Mountain Land Plan (1994) provides the closest parallel in Virginia, seeking to protect, "forest resources, surface water quality, ground water, wildlife habitats and ecosystems, scenic values, and well-sited development compatible with the above five resources." The Committee also considered the balance between public values and the private interests of the mountain landowners in developing recommendations.

In fact, mountains may be said to define much of the character of Albemarle County. Directly and indirectly, the County's mountainous areas provide tens of millions of dollars to the local community in employment, tourism, and agricultural and forest products. Beyond the economic benefits, the mountains provide important natural functions, such as provision of clean water, contributions to healthy air, and habitats for many of the County's plant and animal species. And, to many residents, the blue backdrop of the mountains gives Albemarle County in large measure its "sense of place," that quality which makes this area a special place to its residents and visitors and consistently ranked among the top places to live in the United States. SUMMARY OF RECOMMENDATIONS- ........................................... 1. Delineation of a Mountain Overlay District describing the area containing the critical resources of the mountains, and recommendations which ensure health and safety of the mountain area's residents and control possible degradation of County's resources from activities within the District. These recommendations are applicable exclusively within the Mountain Overlay District. 2. Recommendation of County-wid~ application: Lighting Ordinance. ADDITIONAL PLANNING TOOLS Recommendations in this category assert the fundamental premise that planning for a sustainable future of the County must examine the County, its resources and developmental needs, from a comprehensive point of view. These strategies for the protection of mountain resources benefiting the County and City of Charlottesville proceed from the assumption of an interrelation between healthy rural and healthy urban areas, ALBEMARLE'S MOUNTA ' RESO CES Albemarle's mountains are unique areas of the CoUnty Which are distinguiShed by the natural resources and physical conditions listed below. Such resources and conditions are found in other areas of the County, but only in the mountains do they occur in such combination, as extensively, and to such extremes. Critical Slopes: In Albemarle's mountains COntinuous critical slopes in-excess of 50% can be found for distances of up to one mile, and in some cases, longer. Concerns regarding disturbance of steep land become pronounced in mountain areas due to generally shallow soils and length of grade on side slopes. Soil erosion, surface water runoff, and septic system contamination are amplified in these areas. Soil: Forest cover is the optimum land use for minimiZing S°il erosion and'maXimizing Water quality. Soils on steep slopes are typically more erodible than in other areas. Inaccessibility and isolated location of development sites in mouhtain areas necessitate longer driveways and access roads over more highly erodible Soil's ~h~iii.~6~i:~/i:~i~f~`t~ie~C6i~fi~~i~{i.~w~.~?s~i~.~s roads disturb many times more land area than a dwelling itself. The United states Department of Agriculture states in Handbook 537, "Both the length and steepness of the land sloPe substantially affect the rate of soil erosion by water." (p.12) This Handbook reports that, other variables such as cover and soil type being equal, soil loss on a slope of 20 degrees is 3 1/2 times greater than soil loss on an equivalent slope of 9 degrees. When the length to 600 feet, as in"a mountain slope, the soil loss is 10 times as great. Albemarle County Comprehensive Plan: "Soils are a natural resource which require proper use and preservation...Improper use of soils may '~-esult in accelerated soil erosion and sedimentation, ground or surface water pollution, landslides, flooding, drainage problems, failed septic systems, construction problems, and unproductive agricUltural and forestal lands." (p.75) Water Quality and Quantity: addition to increased demand will necessitate the building of the 26 milliOn dollar Buck Mountain Reservoir before 2040. The South Rivan~aReserv0ir loses 13 million gallons of storage capacity annually as a result of sedimentation. The Ragged Mountain Reservoir, by contrast, loses no appreciable capacity. Albemarle County COmprehensive Plan: "Goal: Protect the County's surface water and ground water supplies for the benefit of Albemarle County, the City of Charlottesville, the Town of Scottsville, and downstream interests .... Protection of water resources is of vital importance to Albemarle County and Virginia in general. Albemarle's location adjacent to the Blue Ridge Mountains provides both the advantage of clean headwaters, and a responsibility to protect them. The County's Rural Areas play a crucial rolein water supply protection::.The maintenance of pasture and especially forestal areas is generally beneficial to water quality."

The principal threat to the County's mountain forests and farms has now become fragmentation and conversion to residential land use. The County's Agricultural/Forestal Industries Support Committee states," Continued forest fragmentation is probably the bigges~ thr~at to the future viability of the forest industry in Albemarle County...As parcel size declines, operability for timber harvesting decreases. Forest sizes below 40 acres are difficult to manage economically. The proximity of houses and other structures escalates the problem."

Albemarle County Comprehen.sive Plan: "Wildlife is a renewable natural resource which requires both protection and harvesting for proper management. The mountainous areas' of the County contain the more dense populations of wildlife..." (p.75) Scenic Resources and their economic impact: 'Albemarle county is well known fOr its scenic character.

A number of highly'ViSible` st~c~i:es'-~o'ns~fucte-d i-e~6ntly have occasioned public concern about the continued scenic quality of the mountain landscape. Public expression of concern suggests that the scenic quality of the mountains is important to County residents. Albemarle County Comprehensive Plan states, "Objective: Preserve the County's scenic resources as being essential to the Cou.nty's rural character, economic vitality, and quality of life. (p.83)... An "issue that is of importance to'visual impact is the horizon. In a county with as much varied topography as Albemarle, the natural horizon becomes very 'prominent. Any serious modification of the natural ridge lines in the County will modify the visual character of an entire area."(p. 87) UVA ObserVatory, Fan Mountain Photograph courtesy of G. Carleton Ray Dark Sky: Excessive outdOor lighting in the urban and developed areas of the county is increasing. The natural resource of dark night sky and its importance to the University's Observatories has been insufficiently considered in planning processes in the County. Energy wasted nationally from poorly designed outdoor lighting amounts to more than a billion dollars a year (International Dark Sky Association, 1990) Poorly designed outdoor lighting creates glare, which compromises safety especially for drivers, .degrades the quality of the entrance COrridors leading to the City and degrades the quality of the built environment. Tourism: TOurism and associated economic benefits related to the mountains continue to grow in the county. Travel sales in 1994' accounted for 17% of total sales or $109,139,211 in the County. Each year approximately 1,985,000 People visit Shenandoah National Park. Direct economic benefit to coUnties adjoining the Park is approximately 85 million dollars per year. In 1990 there were 550,183 visitors to Monticello, which translates into over 159 million'dollars ih"i;eo~fi'U'~'~'fb' the County. Southwest MOuntains Near PantoPsDe~el°pment Area Ray HISTORY OF MOUNTAINP TID [ ALBEMARLE COUNTY COMPREHENSIVE PLANNING Mountain resource protection efforts began in 1971 with the adoption of the ~Count~'s first Comprehensive Plan. One of the Plan's six Goals was: Respect conservation values, including the preservation of stream valleys, mountain slopes, watersheds and other open space areas. The Land Use Plan delineated the mountains as conservation areas. The Natural ResoUrCe Objective was: Albemarle County is rich in natural resources which include beautiful st!lcm ya!leys' scenic mountains, abundant woodlands, wildlife habitations, and mineral dePoSitS. A..~ of these resources are irreplaceable assets which deserve recognition, protection, and proper management. A strategy was: Mountain slopes of 15% or greater ShOUld be built upon 0nly under carefully exercised controls; slopes of 25% or greater should not be allowed to develop. 'The 1977 Comprehensive P1an contained the following Goal for the Conservation'~0f Natural Resources: Conserve the c6Unty's envimnmeni and the baiance r~iits natural ~01o~'.'' This requires the conservation of water supply impoundment watersheds, the best agricultural land, mineral deposits, forests, steep slopes, hilltops/ridges, open space vistas, water quality in streams, and flood hazard areas. These areas should be protected from intensive commercial, industrial, and residential development. A map of Conservation Areas included hilltopsl major ridge lines, 'slopes Ovei; 15%, streams/rivers and their valleys, and th6' Rivanna Reservoir watershed. In addition, conservation measures were also proposed for the County's woodlands. Hillside development standards were proposed on slopes exceeding 15%, which included' road construction, grading and drainage standards. In 1980 a new zoning ordinance was adopted, which included the Rural Areas zoning dist~ff6t to restrict rural development rights, and the critical slopes provisions. Nearly every mountain is zoned Rural Areas, and is` affected by the devel°pr~nt rights restrictions, except two small peaks in the Urban Growth Area. The critical slopes provisions require a. building site, a contiguous area of land in slopes of less than 25% The regulation is intended to implement the Comprehensive Plan by protecting and conserving steep hillsides together with public drinking water supplies and flood plain areas and in recognition of increased potential for soil erosion, sedimentation, water pollution and septic disposal problems associated with the development of those areas described in the Comprehensive Plan as critical slopes. It is hereby recognized that such development of critical slopes may result in: rapid and/or large scale movement of soil and rock; excessive stormwater run-off; siltation of natural and man-made bodies of water; loss of aesthetic resource; and in the ~ye,nt.0/~ septic system failure, a greater travel distance of septic effluent, all of which constitute POtential 'dangers to the public health, safety and/or welfare. The 1982 COmprehensive Plan included envirOnmental standards to protect and conserve natural resources. The Plan states: Clearing, grading, building, cropping or overgrazing of critical slopes can result in extensive erosion and landslides or sloughing of soil and rOck; excessive stormwater runoff; increased siltation and sedimentation of natural. and man-made bodies of watei:i' 10ss of aesthetic resource and in the event of septic system failure, a greater travel distance of Septic effluent. The 1989 Comprehensive Plan states that, 'Natural, scenic, and historic resources are essential to Albemarle County's rural character, economic vitality and quality of life. Tlae'Plan notes'the-Str6ng relationship between these- environmental resources, water supply protection, and agricultural/forestry preservation, which are the major resorts for protecting the RUral Area. 'The Plan also notes the interd~pehde'fi~; ~6f' en:vironmen~ resources, For ex,pie, the"~iiiht~ii~ri~e"O~f forested areas protects surface water quality, wildlife habitat, critical slopes, groundwater recharge areas, and air quality, The 19gg'Plan also discusses design~Standards-for sceni'c'~reiisui:ceil in a county, with as much varied topography as Albemarle, the natural hOrizOn beCOmes verypi:omih~ntl Any serious modification of the natural ridge lines in the 'COUnty-Will modifY the ViSual Character 0f an entire area. The Plan recommended adoption of an Open Space and Critical' ReStdi~ plan,'to identifY and to develOp` Protection measures for significant natural and scenic resources, including critical slopes, important wildlife habitat, wooded areas of envirOnmental importancel afid~hilli0pS The Open Space Plan, adopted July 15, I992 aS'an~amendment to the Comprehensive Plan , {d~hiifi~S l~ltUfiiains as One of four major open Space systems Which are th~ most im~ahi'0pen.- space lands to protect. It lists resources associated with mountains: critical slopes, scenic views, wildlife habitat, extensive forests, unique soils for orchards, natural areas (iricluding 'geologic features, and habitats for rare and endangered plants and animals), and headwaters. The Open Space Plan. defines mountains by a designated elevation contour line, based generally on location Of critical slopes and areas of visual impact. ' The Open Space Plan recOmmends' the following strategy which was aiso-"added to the Comprehensive Plan aCtion agenda: a protection district to protect the SCenic and aesthetic :values associated with mountains, and to further protect their environmental characteristics." 'The plan states: Visual concerns related to mountains center on disruption. of' the ~relafiv'ely pristine wooded character which prOvides a sense of continuity, natural beauty, and wilderness. Extensive ~ritical slopes, combined with high elevations, result in a prominent display of changes to the mountain landscape. Activities which alter the continuity of the ridgeline or result in excessive tree' rern0vat"s'hOuld be discouraged. 10 Environmental concems include the loss to development of a unique and beneficial natural envirenment, and disruption of the natural balance of soils, slope and vegetation. While detailed studies have not been undertaken at this time, it is anticipated that due to the location of generally unspoiled and extensive forests, together with a relatively small human and domestic animal population, mountains may be areas of comparative significance as "natural areas" and "wildlife habitats." Mountains also provide areas of unique soils suitable for orchards and vineyards between elevations of 800,1800 feet. Environmental benefits of undisturbed forests often associated with mountains include increased groundwater recharge, surface water quality, and climate modulation. In addition, concerns regarding disturbance of steep land become pronounced in mountainous regions due to generally shallow Soils '~dieri~thT'bf grade on side slopes. Issues related to soil erosion, surface water runoff, and septic system contamination are amplified in these areas. The mountain land is largely within the Rural Areas Zoning Classification which permits 5 small lot divisions per parcel with residual hcreage divisible' into 10ts of 21 acres or larger. Building requires a 30,000 sq. foot site of less than 25% slope; there are no current regulations limiting the slopes'upon which driveways may be built or the steepness of driveways. The Southwest Mountains are recognized as a National and State Rural Historic District. No land use regulations accompany that designation. The Open Space Plan identifies the mOuntains as one of four major open SPace systems and defines the mountains by designated elevation contour lines. The Plan recommends adoption of regulations to protect mountains. 11 MOUNTAIN DISTRICT ~EVATION ~ ~ooo ~. oR ~o~m 900 Ft.

Application: The boundaries of this DistriCt are intended to encompassmountain areas of critical slopes and areas above such critical slopes that are highly visible and may be dependent for access. on the areas of critical slope beneath. The District's boundaries are delineated by contour line in the map labeled Mountain Overlay District and a~c~i~'~i ~h'~' ~{'"~'~ii~'~-'~(~ind in the Albemarle County.

This provision is intended to prevent the development of concentrated runoff high on the mountains which may have negative impact on soil stability and water quality below. In addition, preservation of the natural horizon is a stated objective of the County's Comprehensive Plan (p.87) and is consistent with Va.

' ................................ the creation' ........ of a convenient, attractive and harmonious community" and "preservation of agricultural and forestal lands and other lands of significance for the proteCtion Of the natural environment'' among the enabled purposes of zoning regulations. Benefit/Cost: Little economic impact will be felt because most of the areas 'defined as Ridge are not currently accessible for building activity. The small economic gain of the building on the Ridge is offset many times by the damage infli~ted-~ii-~}i'e' c) Building sites: Building on parcels partially inside the Mountain Overlay District shall occur on the portion of the parcel outside the District unless iris demonstrated that a building site is' not available outside the District. ' ' This provision is intended to direct development away from the most environmentally sensitive and visible portions of those parcels partially within the Mountain District without affecting the number of development rights on the parcel. Development in remote locations is most costly to the County in terms of providing services. Benefit/Cost: This provision would benefit soil conservation, water quality and scenic resources ' by directing development away from environmentally sensitive areas, and lessening the length and impact of private driveways traversing steep slopes. It would limit the danger of wildfire and landslide. Administration would require i minimal amount of added staff time. d) Allocation of Develooment Rights: Subdi~/i~i0n""of~a"~a~'c~i' phrtiaily~ i~side-ii~e'-M~untain Overlay District Shall allOCate ail de~eiiJ~Jinen~ rlgfi'ts '~'0~' smaiiiots"i0 the porti°n ofihe parc¢: outside the Mountain Overlay District unless it can be demonstrated that legal building sites outside the District do not exist.

AMENDMENTS TO EROSION'AND SEDIMENT CONTROLORDINANCE a) Erosion and sediment control permit shall be required for all driveways and houses in the Ei:0sion and Sediment Control Ordinance and comply with the provisions of ~at Will' sUbstantially ~redu~e~ 0msite erosion and off_site depOsi~Oni' 'Ciii~i/~; agreement, and if necessary a soil erosion plan are required to be submitted for the construction of any single family dwelling. This proposed ordinance would require a Plan instead of an agreement t° be submitted,. ~d would include ~e driveWay with the house~ centerlines and culvert locations will .be ac~ceptable instead of driveway plans and profiles. Identical amendment to the Erosion and Sediment Control Ordinanc~ is included forclarity in these I6 Benefit/Cost: Erosion control does add to construction cost, but this cost, as in other areas where erosion control is required, is simply a part of the cost of building responsibly. The benefit to downstream water quality and soil protection for future generations far outweighs the cost of these temporary construction measures. b) Land Stability_: No slopes shall be created, that are steeper than 2:1 unless retaining walls, revetments, or other stabilization measures 'acceptable to the County. Engineer are employed. This provision is intended to minimize soil erosion and preVent landslides. The ratio of 2:1 is the steepest slope permitted for bank construction by the County, and bY VDOT in~'the'subdigiSion' ~itreet standards. Slopes that are steeper are not stable and can result in erosion, sedimentation of streams and water supply, as well as damage to life and property through landslides. For' reasons` stated above, these problems are particularly acute in the mountain areas. In areas of predominantly rock this gradient may be increased to i. 5:1 where acceptable to the County Engineer. Benefit/Cost: This provision should assist in controlling the amount of sediment flowing into downstream waterways including reservoirs, and thereby improving or maintaining water quality throughout the County and beyond, and minimizing the danger of mud slides in mountain areas. In the steepest areas, retaining walls or revetments may be a more viable alternative to increased width of grading. Such wall s add to the cost of constmcti on. These areas are likely to be the least suitable for development due to inaccessibility, cost of services and other construction costs. c) Run-off Control: Water'from' ditche~i Storm2drains and rooftops and imnervious surfac¢~- shall be released into natural streams or watercourses .as .defined as.~,'adequate, per the. "Virginia Erosion and Sedifiient Haiidb00k~"'~ ........ This provision is intended to control flooding and soil erosion and creation of gullies caused by swiftly moving, and therefore highly erofling water mn-off, as. well as to minimize degradation in water quality and deposition of sediment downstream Benefit/Cost: This provision would reduce the deposition of sediment onto downstream properties and into the reservoirs. The latter diminishes their capacity and reduce the amount of treatment needed for drinking water especially during' i:ainy'weather. The' cost of engineei:ing runi0ffcontrol so as to comply with this provision should be more than returned in protection from property damage caused by swiftly moving water. d) Driveways within the Mountain Overlay District shall be built with side slopes on cut and fill slopes at 2:1 (horizontal slope: vertical slope) or flatter The steepest allowable side slopes (except 'in rock Cuts) on subdivision streets to be accepted into the State Secondary Road system is 2:1 (i.e., 2 feet of horizontal distance for each one foot of vertical rise or fall). Slopes steeper than this have proven to be UnStable Over time.' Unstable side slopes lead to erosion, deposition of sediment downstream, and in extreme cases, dangerous conditions. These problems are particularly acute in the mountain areas. Where 2:1 side slopes are 17 ~':n0t'feasible, retaining walls, revetments, or other slope stabilization methOdS acceptable i6'the County Engineer must be employed. In areas of predominantly rock this gradient may be increased to 1.5:1 where acceptable to the County Engineer. Benefit/COSt: Building roads and ................. dnveways w~th' ..... s~de' ......................................................................... slopes of~25T or flatter may cost more initially. If long-term maintenance and down-slope damage are taken into account, it is cheaper to 'build with stable slopes from the start. e) MinimUm allowable radihsfo~ ho~izon~ii 'curvatUre of private roads and driveWays shall be 40 feet. Any curve tighter than 40-foot radius on center-line is too tight for straight-bodied trucl/s, and fire trucks. Access to residences in mountain areas is of great concern to adjacent mountain property owners and the general public, because fires in wooded mountain areas Can spread. quickly, with catastrOPhiC results. MoUntain areas usually present no alternatives to a single driveway available to an emergency vehicle. Benefit/Cost: PrOviding access to straight-bodied emergency vehiCles-is an '0verwhelmii:ig when compared to the small and short-term saving of constructing curves of tlghiei; radii. f) Driveways shall disturb no more than 65 feetin croSs-section. If a ten-foot' Wide driveWay is b'dil~i'Bfi-~'fi~e~i~h'h'~'3~:~'f(3~;)~s~f6~e, wt~ih 2:~'~i~ cut an~'~'~d~'fl~fl ~i~ it will disturb approximately 65 feet in cross-section. (See illustration below.)

O' Driveway · """- o'n, 3:'1 S ope ----';' F-' a'~d Fill SectiOns g) Longitudinal gradient on driveways shall not exceed 16% The Virginia Department of Transportation maximum longitudinal gradient allowed in mountainous terrain is 16%. County private road standards for 3-5 lots is 16% maximum. Slopes steeper than this are a danger to all who must use the driveway, including fire, police, other emergency vehicles, and delivery vehicles. While the Committee believes that the County would be wise to institute such a regulation County-wide, there is an especially urgent need to restrict the steepness of driveways in mountainous areas. In the Mountain Overlay District steep gradients are likely to be much longer and the associated accidents more problematic because of the steep side-slopes and remoteness of driveways. Benefit/Cost: Every effort should be made to locate driveways' to minimize grading, length, and impact on existing trees; however, the risk to human life in gradients too steep for safety is too great' = to consider the relatively small savings of alignment going too directly up a steep slope. 2.

Note: Action on the above ordinance should not be delayed pending completion of this study, but rather amended when the study is complete. 19 Develop reSOlUtion for Board' of Supervisors asking power'companies to cease promoting unshielded and inefficient outdoor lighting in the County. The cumulative effect of light pollution from the urban and developed areas of the County has the effect of degrading the dark sky in the mountain areas of the COunty. This natural resource is particularly important for the researCh conducted aithe 'ObServatory On'Fan Mountain. Individual unshielded lights in the mountain areas contribute to the degrading of the dark night sky and'are also highly visible and therefore detrimental to the scenic quality of the mountains. For these reasons the Mountain Committee finds that a lighting ordinance which is county-wide in scope is necessary to proiect the mountain resource of dark night sky. · Energy wasted nationally from poorly designed outdoor lighting amounts to more than a billion dollars a year. · Poorl~g designed outdoor lighting creates glare, which compromises safety especially for drivers, degrades the quality of the entrance corridors leading to the City and degrades the quality of the built environment.

ADDITIONAL PLANNING TOO LS County are not only prominent physical features possessing resources, are ~mportant parts of many human and natural ~;-si6/n~ ifith'~ County and region. Like other County human, cultural and natural resources, they therefore require consideration as components of larger planning issues. Though the Mouniain protection Committee's t~k is to develoP recommendations for the protectiOn of the mOuntains of the County~ Cornmitte feels .~at it fails to complete its task if it does not suggest that planning for the s'c~a~:'areas"bi-i~'6u~,es,~s~ich as the mountains, the Urban areas, or the watershed 20 must be integrated with a more systematic approach which provides for the protection of resource systems, such as drinking water, economic viability of urban areas, or transportation networks. Some of the County's land use regulations developed with a compartment-alized approach to land planning may have unintended consequences for protection of its natural resources and other comprehensive planning goals of the County. Rural residential parcels (5-20 ac.) too small to farm or timber or serve as habitat,, increase sprawl, put unintended pressure on mountain and agricultural lands. Areas of the County possessing critical resources may require different types of land use restrictions to protect the resource. Segregated land uses may unintentionally increase housing costs, and increase pressure on transportation systems and on agricultural lands in the path of proposed new roads. Discussion of natural resource protection, that is, may not be broad enough in scope to suggest effective or equitable solutions. The recommendations which follow attempt to point toward a systematic approach to resource protection for Albemarle County. Develop brochure detailing design recommendations in Mountain Areas Based on the model of Rappahannock County's brochure, "Ridgetop Development," Albemarle should make available to anyone constructing a residence in the Mountain Overlay District a brochure which encourages sensitive site planning. Prospective mountain residents should be educated regarding both .aesthetic and safety considerations. "Being considerate and preserving tho gentle, natural beauty that has drawn us to this County," Rappahannock's brochure suggests, "should be paramount in all our minds." See attached brochure in Appendix 3, County_ of Rappahannock: Pddgetop Development The Mountain Protection Committee is willing to draft such a brochure based in part on information whi ch it has compiled. Inventory_ Albemarle County's Natural Heritage Current knowledge of the critical elements of Albemarle's natural resources, including its biological commtmities is spotty'and Speculative. An inventory of the CoUnty's critical natural resources including rare and unique natural resources is needed to provide property owners, planners and County staff with the information to make wise land stewardship decisions. Methods of conducting this assessment and evaluation should be pursued. The Open space Plan recommends a N&tural Areas Inventory of designated areas for significant natural communities, their sensitive plant and animal habitats, geologic landmarks, and other natural features. TJSPARE proposed such an inventory for the five localities of the'Planning District. Cover Type Analysis and Habitat Evaluation Procedures assessment are also suggested in the Open Space Plan, which cites the lack of information available about wildlife and'aquatic habitat in Albemarle. Support Land Use Assessment Tax The concept of land uSe assessment tax for forest land, agricultural horticultural and open space lands should be continued and defended. 21_ that it generates in tax revenues ($1.16 in costs for every $1.00 in revenues), the undeveloped rural land substantially subsidizes residential use in the county.

The scenic-mountain landscape has been stated as a factor in the Albemarle and Charlottesville tourism industry.

Full Cost Accounting and "ReVenue sharing,, Discussions of revenue sharing between the County and city comprehensive approach and include the flows of benefits and costs in both directions. The City and urban area benefit economically from ecosystem services; notably watershed protection and air quality, provided by rural land of the County. Major economic contributions accrue to the people of Albemarle and Charlottesville as a result of the natural functions of the forests. A disproportionate share of these values are provided by the mountain forests. For example, forest landowners in the county provide watershed protection for the City\County water supply reservoirs. Without the protection of forest cover, particularly on mountain slopes, City and County users of public water would be required to divert hundreds of thousands of dollars from other uses to maintain the .same level of water quality. Full cost accounting of the public water resource would show that rural mountain landowners, who receive little or no benefit from the resource, are bearing (subsidizing) this cost for urban residents and users of the public water Similarly, the mountain forests play a significant role in filtering air,:seqU~steriri~' '~rbon and other air pollutants and improving air quality. Due to climatic patterns, the mountain forests play a greater role in this function than lowland forests. This function benefits the local economy by reducing expenditures for health'¢ai:e and for anfi-POlliid0h' ~eaiui;e~::i~hat Wouldiikely be required in the absence of these forests. Albemarle's forests currently store an estimated 19.7 million tons and annually remove 300,000 additional tons of carbon, as well as numerous other pollutants. Achieving this same level of atmospheric cleansing through anti-pollution measures would cost citizens an estimated $8.4 million dollars that those residents have available for other services and investments due to the role that the mountain forests perform. Efforts that significantly affect the value of mountain forest land for the primary purpose of benefiting the urban area should include incentives, or other strategies. Such full cost accounting is now gaining in recognition in other cities and regions such as New York State. 23 Change in Large Lot Division Size Large Lot SiZe within the Mountain Overlay DiStrii~ti a minimum of 21 acres to a minimum of 42 acres in the Mountain Overlay District.

This trail will require public access opportunity from the trail to the stream bank (See Photograph #2). Photograph #2 It is the intent of the County that the majority of the trails within the greenway system be primitive in nature (Class B); except in those areas where ADA and bicycle accessibility is desired (Class A). A "primitive" type trail is the least expensive to construct and maintain. This type of trail minimizes impervious surface, which helps reduce runoff concerns. Therefore, most trails in the greenway system will be class B in nature. Class A type trails will be located primarily in and near parks and major activity areas. Trail Locations If possible, trails should be located near the water course within the County's designated Resource Protection Area (RPA). A RPA is "an area of land at or near a tributary stream bank and/or a non-tidal wetlands that has an intrinsic water quality value due to the ecological and biological processes it performs". RPA's include a 100 foot buffer along all tributary streams and non-tidal wetlands which are contiguous to the tributary streams. Almost all the greenway segments proposed in this section are planned to be located along water areas designated as tributary streams. There will be many locations along rivers and streams, due to constraints such as topography, soil types, wetlands, habitats or an owner's unwillingness to make available needed property, where a trail will have to deviate away from the water body in order for a contiguous path to be provided. It is likely that most trails in the County will need to meander back and forth from the stream or river in order to avoid these constraints. In some cases, constraints may be such that a trail can not be constructed in certain sections. Trails should not be built on critical slopes (slopes 25% or greater), non-tidal wetlands, or areas identified in the Critical Resources Inventory as areas not to be disturbed. The location of many trails may not allo-~large biiffe?"~e~'io"b6' pi~O~idodq~6~e-Ofi'Lli~'"~Oii~¥;'~Ki[iiii~ adjacent property.

G2-public parking-no major facilities-possible boat access. G3-neighborhood access-parking/other facilities Possible-public or private access. Major Public Access Points (Gl) are to be located at established activity centers such as parks where facilities such as parking areas, drinking fountain, rest room facilities, trash receptacles, etc. are Presently prOvided. They provide a full range of facilities and services. ~ Minor Public Access Points (G2) are to be located at areas where G: 1 amenitie~' ~U~h'~iS' r~s~06ms, water fountains, picnic areas, etc. are not feasible. These access points can be located at schools', offices or at major commercial areas. They provide parking, trail access and possibly boat access opportunities. Provide smaller Neighborhood Access Points (G3) at residential developments. The provision of facilities such as parking, picnic tables, etc. should be determined by the developer/neighborhoOd association. These access points may be either public or private. If the access is private then the County would not maintain the area. It is expected that as new neighborhoods are developed along the greenway system, additional Neighborhood Access Points beyond what is identified on the Greenway C0neept Map will be provided. Trail Access Point LocatiOns Distance between access points should not exceed 2 miles at any point along the trail, if possible. Public access points should be located at various intervals to allow hikes of various lengths/FdtUre and existing residential and larger commercial developments adjacent or nearby a proposed greenway section should be encouraged to provide access to the greenway trails. Existing and planned bicycle routes, sidewalks and other off-river type trails should connect to access points when feasible. In some eases, access points will not be located adjacent to the greenway system. In these cases, an off-river trail will be utilized to access the greenway. Also, access points that serve an ADA and bicycle accessible trail (Class A) should have a similar type trail that provides a connection.

In commercial areas, parking can be provided on the existing lot if excess parking spaces exists. New parking areas should only be constructed in cases where an existing parking area can not be utilized. Benches: When designing or purchasing a bench, consider user comfort, simplicity of form and detail, ease of maintenance, durability of finish, and resistance to vandalism. Provide benches primarily at major accesses and scenic overlooks, rather than along the trail to minimize disturbance along the trail corridor. Site benches on an opportunistic basis. Picnic Areas: Site picnic areas at major access points (Gl) where they can provide for the maximum ~ comfort and enjoyment of the user. Because of their relative large size and high level of activity, picnic areas should be set back sufficiently from circulation pathways so they will not interfere With 'activities on the trail. Signage: The role of the trail signs is to aid and instruct users. Signs are of three types: 1) regulatory; 2) warning; and 3) guidance. Generally, regulatory signs give the operational requirements of the trail such as rules of the trail (i.e. no use after dark, no motorized vehicles-bicycle yield to pedestrians). Warning signs indicate existing or potential hazardous conditions on the trail such as significant grade change and changes in surface conditions. Guidance signs provide trailside information to orient the trail users geographically. These signs can be both directional and informational." Directional signs often point out nearby support facilities and local points of interest. Informational signs include distance markers as well as "you are here" signs which orient the user. These signs should also indicate themil~iSis~tr~and ~li~tance ~o ....... the next access trail and estimated time and distances of various hikes. Informational signs can also serve an interpretive role, pointing out elements like historic sites, locations of historic eVents, and areas of ecological significance. Trails are transportation corridors, and therefore recognizable transportation signs should be adapted for trail use. Although trails should borrow the conventional highway signs, it is not necessary to erect large highway signs on the trail. The scale of the trail is much smaller, so smaller signs are appropriate. Recommendation: Provide facilities on an opportunistic basis and in a manner consistent with the standards in this section. · Provide boat access at appropriate locations, as feasible. · Provide parking as necessary and feasible at major trail access points.

Effect on Property Values and Crime The most comprehensive study to date that refutes the negative impact of trails is "The Impacts of Rail- Trails" study. This study looked at the effects or trails in three diverse areas across the country. Overall, landowners indicated that they used the trails frequently. For example, in the East Bay region near San Francisco, 99 percent of the neighbors living along the suburban Lafayette/Morago use the trail (Source: Moore-The Impact of Rail-Trails). A study of Seattle's Burke-Gilman Trail shoWs similar results with adjacent owners making frequent use of the trail. This study points out that two of the trail's most vocal opponents now believe the trail is the best thing that ever happened to the neighborhood (S0ur~e: Seattle Engineering Department and Office for Planning, Evaluation of the Burke-Gilman Trail'sEffeCt Oh -- Property Values and Crime). The. Burke-Gilman study and a study of trails in Minnesota specifically addresed crime. Both studies showed that landowners concerns about crime diminished once the trail was established. The studies also refuted the idea that trails foster crime toward trail neighbors; the incidence of crime was actually lower in homes' located on the trail versus those in surrounding neighborhoods (S0ui~Ce: seattleEngineering Department and Office for Planning, and Crime and Trails for the Twenty-First Century). Methods of Obtaining Land The following describes in more detail the most common methods Of obtaining land which could be used to implement the Albemarle County greenway network. Purchase at Full Market Value-The cost of buying land at full market value is prOhibitive; however, the County or a land trust may consider buying certain critical segments that would allow the connection of the greenway system. Bargain Sale-A landowner may transfer title of land or a partial property interest, at a price below market value. Generally, a landowner obtains tax benefits as well as direct cash for this transaction. If the organization buying the property is tax-exempt, the land owner may be able to take a charitable contribution deduction for-.the difference'between th~'h~tuai "~ale pric~ and the fair market value of the property. Donation-This is the easiest method of transferring land, as it requires no cash outlay on the part of the recipient land trust or County, and the property can change hands with relative speed. A donation offers the greatest tax benefits to the owner. 12 Conservation Easement-A conservation ease~.~nt~i~s_,~a~lggal agreement a Property owner makes ~ regarding development of his or her property.
