The foregoing motion carried by the following recorded vote: AYES: NAYS: ABSENT: Messrs. Dorrier, Fisher, Henley, Lindstrom and Rouda~ush. None. Dr. Iachetta. Mr. Fisher said he had been presented with a petition signed by citizens in the southern part of the County complaining about the lack of game wardens during the hunting season. This has been turned over to the Sheriff and Mr. Agnor for review. Mr. Fisher said the Virginia Municipal League and the Virginia Association of Counties are sponsoring their annual legislative conferences in December. They request that the individual counties bring their representatives to the General Assembly to these meetings. The closest meeting is scheduled for December 14th in Richmond. Messrs. Dorrier, Fisher and Roudabush agreed to attend. Agenda Item No. 4. At 5:28 P.M., motion was offered by Mr. Lindstrom, seconded by Mr. Dorrier, to adjourn this meeting until November 30, 1978, at 7:30 P.M. in the Greer School Cafetorium for a public presentation of the proposed revisions to the Zoning Ordinance. The motion carried by the following recorded vote: AYES: Messrs. Dorrier, Fisher, Henley, Lindstrom and Roudabush. NAYS: None. ABSENT: Dr. Iachetta. ~ _ _ _ Ch~a~n-- . November 30, 1978 (Adjourned from November 2~ An adjourned meeting of the Board of Supervisors of Albemarle County, Virginia, was held on November 30, 1978, beginning at 7:30 P.M. in the Greer Elementary School Cafetorium, Lamb's Road, Charlottesville, Virginia; said meeting being adjourned from November 29, 1978. Present: Messrs. Lindsay G. Dorrier, Jr., Gerald E. Fisher, J. T. Henley, Jr., F. Anthony Iachetta, C. Timothy Lindstrom (arriving at 7:40 P.M.) and W. S. Roudabush. Absent: None. Officers present: County Executive, Guy B. Agnor, Jr.; County Attorney, George R. St.Jok and County Planner, Robert W. Tucker, Jr. The meeting was called to order at 7:35 P.M. by the Chairman, Mr. Fisher, for a public presentation of the proposed revisions to the Albemarle County Zoning Ordinance. (Notice of this change in meeting place was advertisied in the Daily Progress on November 15 and November 22, 1978.) Mr. Fisher said that after the ~r~7~omprehensive Plan was adopted in 1971, a proposed revised zoning ordinance was drafted~- T~'Zoning Ordinance was drafted to try and implement the '71 Comprehensive Plan. It was not enacted, but sections of that proposed revision have been adopted into the current ordinance over the past few years. This meeting tonight has been scheduled for a joint presentation of the proposed revisions to the Board and Planning Commission by the consultants, Kamstra, Dickerson and Associates. A citizens advisory committ has been working with the consultants on these revisions and have not yet given their recom- mendations. Mr. Fisher said a formal public hearing on these revisions will be held in the near future, however, time will be given at the end of this presentation for comments from those present. He then introduced Mr. Robert Tucker, Director of Planning. Mr. Tucker made some very brief opening remarks and then introduced Mr. Bruce Drenning. Mr. Drenning introduced Mr. Beckham Dickerson and then proceeded with the presentation. He said this is a draft for discussion only and is not ready for adoption. There are 13 sections in the ordinance; nine basically similar to material in the present ordinance. However, four sections have substantial revisions. Most changes were geared to implement the '77 Comprehens Plan. When the consultants were working on the revised Comprehensive Plan, they realized that the County had seen a low level of achievement under the '71 Comprehensive Plan and it was felt that the major reason was lack of implementation tools probably caused by the need for a revised zoning ordinance. The zoning ordinance was adopted in 1968 and since that time many changes have been made, making parts of that ordinance inconsistent. The General Assembly, in 1977, changed the law to state that a Comprehensive Plan must be considered in the zoning ordinance and since these two are not well-meshed in Albemarle County, the County could possibly have some legal jeopardy. Mr. Drenning then listed objectives of the revised ordinan. Encourage growth in the urban area, communities and villages. Limit growth in the rural areas. Conserve natural resources. Better locations for industrial growth. Improve commercial development. Higher quality residential development in neighborhood settings. 1978) ~e .ye e: November 30, 1978 (Adjourned from November 29, 1978) 065 7) 8) 9) 10) ll) 16) Greater coordination between private land use decisions and public improvements for a more efficient expenditure of tax dollars and better services. Implementation of the Comprehensive Plan. Hi-density development be allowed only in the urban areas, communitites and villages. Commercial development be allowed only in the urban areas, communities and villages. Increase density differentials. (i.e.. if allowed the same density of development in the rural area as in the urban or suburban area, there is no incentive to locate in the urban area, so a larger lot size is recommended for the rural area.) Environmental protection tools. (These are contained in the overlay zones to provide incentives for quality development and to provide methods for development to be clustered. Industrial development will be planned-type only. Will refer to the Comprehensive Plan for map locations of best places for industrial development. Commercial Districts will have functional areas for special kinds of commercial uses. Provide for a wide variety in types of housing. ' Expand~ on the types of units allowed in different residential zones. Have a more rational review of rezoning decisions with better timing. Mr. Drenning said in relating the Comprehensive Plan to the zoning ordinance, the follow- ing residential zones were created: For the rural area: Village Residential (VR) which is one dwelling unit per acre,. For the urban area and two communities (Crozet and Hollymead) a variety of districts were created: Residential Suburban (RS-I) similar to the present ordinance provisions of one dwelling unit per acre. Two other single-family zones: Residential R-2 which is two dwelling units per acre and Residential R-4 which is four dwelling units per acre. Also there will be three Planned Development Reesidential Districts (PDR) with densities from four to 20 units per acre. This also allows development from single-family to apartments. To implement the woodlands and conservation concerns of the Comprehensive Plan, it is recommended that there be specific restictions on the amount of woodlands that are cleared during residential development. For protection of steep hillside areas, an overlay district that requires a lower density as the slope of the land becomes steeper, is proposed. For flood hazard areas, a Flood Hazard Overlay District is proposed. This has been brought up to date and is coordinated with HUD regulations on the Federal flood insurance program. For agricultural land use, there is a Best Agricultural Soils Overlay Distrist (BAS). For other rural lands, a Rural Residential District (RR), which has a range from one and three-quarters acre to two and one-half acres lot size. For visual quality concerns, there is Scenic Areas Overlay which has a scenic highway component and a scenic stream provision. Mr. Drenning said the heart of the new ordinance is contained in Section III, which is the schedule of district regulations. In the existing ordinance there are two concepts for planned development, or the RPN and PUD regulations. The purpose of the PUD regulations were to provide flexibility not found in the typical zoning or subdivision ordinance; to allow and encourage better design; to provide higher levels of amenities; to require protection of the natural environment during and after construction; to improve coordination with utilities, public facilities and transportation; and to allow a mixture of land uses. Ail of these applied to residential development. The PUD concept has been expanded so that it may be applied to commercial, industrial, and special activity type zoning districts as well as to residential. For purposes of distinction, the approach is now generally referred to as Planned Development Zoning and is proposed to also include Industrial, Commercial, and Resi- dential zoning districts. Planned development regulations provide flexibility in terms of location, land ownership, permitted mixtures of land uses, and provision for open space. Some of the important provisions of planned development regulations in the proposed ordinance include: a) b) c) d) e) provision and flexibility for properties under multiple ownership to be developed as a unified project. provision of development programs, including timing. requirements for detailed plans. provision of defined options for providing and maintaining open space. location of planned development districts in accordance with the Comprehensive Plan and with detailed locational standards in particular planned development districts. 066 November 30, 1978 (Adjourned from November 29, 1978) f) requirements that planned development districts be related to public and private facilities existing or to be available. g) procedures for processing and approving applications including prehearing conference, content of planning commission report on application, optional imposition of time limits for submission of site plans and other developer actions. h) flexible content of site plan, including changes. i) specific provisions for bonds and guarantees. J) optional review by planning commission and recommendation to supervisors concerning continuation or change in zoning granted where time limits or other requirements are not fulfilled by owner. Mr. Drenning said in numerous instances, zoning districts existing under the present ordinance will be converted to pl.anned development districts upon enactment of the new ordinan and they will be so designated on the zoning map. For example, all land to be zoned industria will be zoned for either Planned Development-Light Industry or Planned Development-Heavy Industry (converted from M-I, M-2, or RTM)~ some lands zoned B-1 may be converted to Planned Development-Highway Commercial, Planned Development-Shopping Center, or Planned Development- Commercial Office; and some lands now zoned RPN, R-2 or R-3 may be zoned for Planned Deve!opme Housing. Following enactment of the new ordinance, such converted lands will be subject to the new requirements, however, no concept or site plan will be required until an owner is ready to develop. Mr. Drenning said it is proposed that the three existing industrial districts (M-i, M-2, RTM) be replaced by two planned development industrial districts: one for light industrial uses and one for heavier industrial uses. This parallels the existing ordinance structure where M-1 and RTM are predominantly light industry, and M-2 provides for heavier industry. The new regulations are designed to give more control over the planning and development of industrial lands and to implement the Comprehensive Plan for industrial growth in terms of both location and amounts of land. In the Planned Development-Industrial Districts, limitations on building coverage have been reduced from 70% to 50%, and a maximum floor area regulation (70%) has been added, off- street parking requirements have been changed so that they are now geared directly to levels of employment for industrial uses. Performance standards for industrial uses are proposed to be expanded to apply to all industrial districts instead of to just one of the industrial districts as is the case in the present ordinance. The proposed regulations add specific site plan requirements which deal with the protection of surrounding areas as well as provisions for handling traffic to be generated by new developments. The proposed Planned Development-Light Industry District corresponds generally to the M-1 and RTM districts in the present ordinance. Locational criteria have been added in the proposed regulations which includes major highways, public water and sewer, and the suitabili and relationship of the development to surrounding land use. The recommended permitted uses reflect an intent to limit uses to industry, and to switch previously permitted commercial uses to commercial districts. Within that framework, appropriate uses now permitted in M-Z and RTM are permitted in the new Planned Development-Light Industry District. The proposed ordinance provides a minimum area of five acres for a new Planned Development-Light Industry District and a minimum lot size of one acre; the existing ordinance simply requires 40,000 square feet for a lot. The proposed regulations require landscaped open space, screening, and specific distance separations from residential areas. The Planned Development-Heavy Industry District parallels the existing M-2 zone in terms of permitted uses. Locational standards are not as limited as those for the Light Industry District. Requirements for landscaped open space, screening, and distance separation from residential areas are included. Mr. Drenning said the commercial districts provide for retail, wholesale, and service uses and restrict those uses in accordance with the Comprehensive Plan to the urban area, communities, and villages. The commercial regulations emphasize coordination of new develop- ment with transportation facilities. The proposed regulations recommend the creation of four commercial districts which are organized along functional lines and would replace the present B-1 and CO districts,: Business District -- for locations in the urban area and communities which have central business concentration characteristics including pedestrian orientation. Planned Development-Highway Commercial -- for a wide variety of businesses which are primarily automobile-oriented. Planned Development-Commercial Office -- for professional and general business office concentrations. Planned Development-Shopping Centers -- for shopping center concentrations of commercial development. New regulations for business districts provide a more limited list of permitted uses thai are provided in existing B-1 regulations; the dual purpose of such limitation is to identify those retail and service uses which are primarily oriented to central business concentration locations and to create an i'ncentive/rationale for conversion of existing undeveloped B-1 lands in highway locations to be established as Planned Development-Highway Commercial Distri¢ A maximum building coverage requirement of 40% has been added to fill a void that exists in the current ordinance. The new regulations propose that the lot sizes currently required for business uses be increased by 10,000 square feet in the business district. e ~y ts. h~o~ember 30, 1978 (Adjourned from November 29, 1978) The Planned Development-Highway Commercial district is intended to accomplish the purposes of planned development in general, and further, to encourage concentration of commercial uses and control strip commercial development in a manner superior to existing controls. The permitted uses in this district incorporate all commercial uses from the present B-1 zone and add commercial uses now permitted in the M-1 zone of the existing ordinance. A minimum area of from two to three acres, depending on utilities, is recommended to encourage districts large enough to accommodate concentrated groupings of commercial uses. A frontage require-ment (150 feet) is recommended for the same purpose. Minimum area require- ments for individual lots correspond to those presently permitted in the B-1 district of the existing ordinance. Planned Development-Highway Commercial regulations also include site planning standards which emphasize traffic, parking convenience, and relationships to sur- rounding areas. The Planned Development-Shopping Center district is created expressly to recognize and regulate shopping centers as a distinct type of commercial use area. The district contains specific reference to standards in the Comprehensive Plan and establishes locational criteria for neighborhood, community, and regional shopping centers. The Planned Development-Commercial Office district parallels the CO (Commercial Office) zone in the current ordinance. As in other planned development districts, additional control in the area of site planning with emphasis on traffic and relationships to surrounding areas are included. The proposed regulations for Residential Districts include eight residential districts which are as follows: VR-Village Residential. This district is created to implement the villages portion of the Comprehensive Plan. This entails encouraging residential and supporting development in designated village locations. To accomplish this purpose, a special district is created which permits compact development in accord with local health requirements. A mixture of residential and supporting non-residential uses are permitted. This zoning designation is intended to replace existing R-i, RS-I, and R-2 classifications in appropriate village locations. Lot sizes will range from one acre to one and four-tenths acre. RR-Rural Residential. This district is proposed to replace most of the County's A-i zoning. Criteria are established in the proposed regulations to encourage conservation of the natural and scenic environment. Lot sizes will range from one and three-quarters acre to two and one-half acres. RS-l-Residential Suburban. This district is proposed to accommodate residential development in the urban area and in communities at suburban densities in locations where public water and sewer facilities are not available or expected to be available for a considerable p~riod of time. Lot sizes will range from one acre to one and four-tenths acre. Residential R-2 and Residential R-4. These districts are provided to permit single family development in the urban area and communities at suburban residential densities approximating two dwelling units per acre and four dwelling units per acre respec- tively. These districts are to be located oa~~ where sewer and water facilities are now available or are to be available within the near future. Mr. Drenning said the proposed ordinance contains three Planned Development-Residential districts which are intended to replace the RPN, PUD, R-2 and R-3 districts. The three districts are called: PDR-17 (Planned Development-Residential-17); PDR-27 (Planned Develop- ment-Residential-27) with densities from eight to twelve units per acre; and PDR-41 (Planned Development-Residential-41) with densities from eight to 22 units per acre. The number is a reference to the maximum permitted floor area ratio which can be applied in the district. The use of'floor area ratio in residential districts is different from the traditional concept of regulating density by limiting the number of dwelling units per acre. Regulation on a dwelling unit per acre basis does not tell you whether a developer is going to build all one-bedroom units or all five-bedroom units, or something in between. Provision in the new ordinance might dictate that a 100-acre tract have a floor area ratio of 10% yielding 430,650 square feet of residential floor area. The developer could then build either 215 dwelling units at 2,000 square feet each or he could build 430 dwelling units at 1000 square feet each, or something in between. The total population, and the overall population density for the development, would be approximately equal in either case. This knowledge is extremely valuable to the County in that it provides an accurate basis to plan for public facilities, and to project possible economic impact of developments. The Planned Development-Residential districts permit mixtures oF uses including indus- trial and commercial, under certain specified and closely controlled conditions. Mixing of types of residential units within these districts is also permitted. Although design regu- lations are flexible, standards are provided for both internal and external consideration for site planning. Specific guidelines for management of open space and common facilities are provided within the "Guides and Standards" section of the planned development regulations. The PDR-17 district provides an overall density which corresponds to approximately four dwelling units per acre if a development contains all single family dwellings. The PDR-27 district corresponds to the townhouse density currently permitted under provisions of the R--2 zone of the current ordinance. The PDR-41 district provides a density corresponding to approximately 20 dwellings per acre and allows a maximum practical density (at an average of 700 square feet per unit) of 25.7 dwelling units per acre. It is felt that this density is suffi- ciently high for apartment type dwelling in Albemarle County. This does not preclude high rise building types; it just limits the overall density. :068- November 30, 1978 (Adjourned from November 29, 19~8) Mr. Drenning next discussed cluster development which changes the lot size for a parti- cular development, but does not change the density and which can be used either under standar¢ development or where bonuses are granted to increase densitY, Cluster development is optional except in the Best Agricultural Soils district. A full yield is allowed under cluster development. For example, under present A-1 zoning which calls for two acre lots, if a new road must be developed, only four lots could be put on a 10-acre parcel. Under cluster development provisions, five lots could be obtained. Under clustering, 25% of the land must be in open space and only 30% of that open space can be unusable. Also provided are pro- visions that the County must approve the legal arrangements for maintenance and ownership of common open land. Mr. Drenning said State enabling legislation does not specifically empower the locality to address quality issues; only health, safety and welfare issues. It is felt this can be encouraged by use of incentives and that is the reason for incentives (Bonus levels for Residential Districts). These are incentives for an owner or developer~to create a resi- dential development which is superior to a traditional subdivision in terms of accomplishing specific goals, objectives, and standards of the adopted Comprehensive Plan. Bonus levels permit an increase in dSnsity of development together with corresponding sma%ler required lot sizes and smaller dimensions of frontage and yards. Bonus levels less than the maximum allowable can be granted to an owner or developer depending on the number of incentive factors which are incorporated in the development plan'and upon the degree to which the development plan fully accomplishes the purposes specified for-each of the bonus level incentive factors. Bonus .levels are handled administratively in the proposed ordinance and will be granted or denied during the regular subdivision process. In Residential Districts both a minimum and a maximum lot stze have been suggested. It is felt that the use of large lots is uneconomical and not an efficient use of land. .Also, there is no public advantage to large lots and the market may be corrected through the use of smaller lots. Overlay districts are environmental regulations and supercede the districts they lay over. There are ways to handle these concerns other than through the overlay districts, such as repeating a set of regulations in each section of ~he zoning ordinance. The overlay district is. proposed to avoid that. There are six overlay districts: flood hazard, ai.rport impact, best agricultural soils, scenic areas, hillside, and natural resource extraction. The Airport Impact Zone is geared to the Charlottesville/Albemarle Airport and is for the purpose of minimizing hazards and obstructions to aircraft. Most uses in. this zone will be by special permit and there will be no cluster development allowed. The'Best Agricultural Soils Overlay is designed to conserve the County's best agri- cultural soils. It is aPplied only over the Rural Residential District. A bonus would be given for developing wooded areas first. If open, or cleared areas, are developed first, there is a penalty. Where a property does not have any woodlands and there is a hardship, it could'be developed at the basic rural residential density except, it would have to be develop~ as cluster development. There would also have to be a permanent agricultural easement placed over a portion of the land. Densities for this district would be the same as those for Rural Residential, or one dwelling unit per two and one-half acres. Under a penalty situation, one dwelling unit for each five acres of open land or one dwelling unit for each two and one-half acres of wooded land, would be allowed.~ Basically, a higher yield can be obtained in terms of the number of lots thaN would be allowed udder existing ordinance provisions for A-1 zoning. This is accomplished while still preserVing open land. A Scenic Areas Overlay District has been created. This is for year-round streams which are not already protected. There will be 50 feet on each side of the Stream where no buildin would be allowed, but the area could be counted as part of the lot or the yard. There is no development penalty and if a permanent c~asement is put over that 50 feet, up to a 20% densit bonus is provided. Scenic Highway provisions are similar to present regulations. 150 feet on each side of the right-of-way is put in the scenic highway zone, but the area can be counted as part of lots and yards, while also providing up to a 20% bonus for residential land in this zone. Off-street parking will not be allowed closer than 50 feet unless it is two spaces or less. Exceptions have been added. In many areas where nothing can be seen because of topography, thick tree cover or existing b~ildings, building will be allowed in that strip. Sign regulations have been simplified to allow a sign one-half the size of the sign normally allowed in the particular district through which the scenic highway runs. The sign face has'also been decreased to standard levels which are smaller than in most districts A Hillside Development District is recommended to prevent environmental damage and applies only where slopes are over 14%. Bonuses have been limited by stating that the bonuse: for the underlying zone are only applied to the suggested densities proposed for this zone. Run-off control is required to prevent erosion and other environmental effects. Construction standards are provided and cluster development will be allowed. The Natural Resources Extraction Overlay zone provides basically for mining'and requires a permit, a plan, a 20-acre minimum site, fencing, landscaping, and regulations on hours of operations, keeping roads clean, and controlling the amount of noise. Mr. Drenning said the general regulations section of the present ordinance is not very extensive. It has been expanded to include all basic sign regulations. The amendments sections has several significant changes. There are specific guidelines included for things the Planning Commission and Board should consider on a rezoning request. Also recommended, is that the Board only act on rezoning requests four times a year. This was recommended because when dealing with rezonitg~ requests on a month-to-month basis, it is easy to lose sight of the impact of individual actions. A number of Virginia jurisdictions have gone to this concept because the governing body has a better idea of the impact of approving such requests. 'Mr. Tucker then gave a brief summary of how the zoning map was drawn. Criteria used were: 1) the Comprehensive Plan was used as the basic guide. 2) the 1932 soils map. 3) the community, neighborhood and village plans which are complete at this time. 4) lands under the land use taxation program. 5) the summary of proposed district regulations prepared by the consultants. Novembe~ 30, 1978 (Adjourned from November 29, 1978) December 6, 1978 (Regular-Night MeetSng) Mr. Fisher said guidance to this point has been furnished by the Steering Committee and the Citizens Advisory Committee. He asked that groups with comments to make on the proposed draft, put them in writing so the comments can be studied by the staff. He said it is his hope that the Board can hold its first public hearing on the ordinance on January !1, 1979. Mr. Fisher then called on the public for comments. After a short question and answer session during which several members of the public complained about the short time schedule for adoption of the ordinance, Mr. Fisher noted that he had scheduled a work session on the ordinance for the Board in January and that was the reason he wanted to get the ordinance before the public tonight. He asked the Planning Commission's schedule. Uol. William Washington, Vice-Chairman of the Commission, said they have a work session scheduled for December 4th with a public hearing set for December llth. At 9:35 P.M., the meeting was adjourned. ~Sgfairman December ~, 1978 (Regular-Night Meeting) A regular meeting of the Board of Supervisors of Albemarle County, Virginia, was held on December 6, 1978, beginning at 7:30 P.M. in the Albemarle County Courthouse, Charlottesville, Virginia. Present: Messrs. Lindsay G. Dorrier, Jr. (arriving at 7:35 P.M.), Gerald E. Fisher, J. T. Henley, Jr., F. Anthony Iachetta, C. Timothy Lindstrom and W. S. Roudabush. Absent: None. Officers present: County Executive, Guy B. Agnor, Jr.; County Attorney, George R. St. John; and County Planner, Robert W. Tucker, Jr. Agenda Item No. 1. The meeting was called to order at 7:30 P.M. by the Chairman, Mr. Fishe~ with a moment of silence. Agenda Item No. 2. Request for Central Well. Mr. Agnor noted receipt of letter from Joseph C. Hearn, Jr. requesting permission to install a central well system to serve six one-bedroom cottages to be constructed on 12+ acres on Old Lynchburg Road. The property is known as Tax Map 89, Parcel 53. In his letter, Mr. Hearn noted that the site plan for these cottages has been approved by the Planning Commission and the owner of the property is H - W Associates. Mr. Agnor said the property is located within the Service Authority's jurisdictional boundaries, but is more than a mile from the end of the line, therefore it is not feasible to connect this property to public water. Mr. Hearn was present and said it is a matter of drilling one well to serve these dwellings, or drilling several wells. The parcel is undivided and there will be six rental cottages constructed. Motion was then offered by Mr. Roudabush, seconded by Dr. Iachetta, to approve in concept the drilling of a central well as proposed by Mr. Hearn. The motion carried by the following recorded vote: AYES: NAYS: Messrs. Dorrier, Fisher, Henley, Iachetta, Lindstrom and Roudabush. None. Agenda Item No. 3. Amend Section 18-22 of the County Code and Section 17-5-13 of the Zoning Ordinance to establish performance standards for off-site and on-site drainage facilities. (Deferred from November 1, 1978.) Mr. Tucker said these amendments will serve to clarify that on-site and off-site drainage facilities are the developer's responsibility. Generally the rate of post-develop- ment runoff will not exceed that which existed prior to development. Increased runoff due to development is a concern often expressed by adjoining property owners at Planning Commission meetings. These provisions will be applicable to areas outside of the South Fork Rivanna River Watershed. The County Engineering Department prepared a study of the proposed storm water detention ordinance in which it is stated that, "for several years, the attention of the County Staff has been called to the incipient drainage problem which is inherent in the change of large areas of land from natural cover to impervious s~,~rfaces. The consideration of plans for the development of a large shopping mall on-the Meadow Creek Watershed persuades the County Staff that it is time to propose an ordinance for the purpose of controlling storm water discharge to the extent necessary to prevent excessive and unnecessary flooding." Mr. Tucker said the staff of the Engineering Department and the staff of the Planning Department met with representatives from the Blue Ridge Home Builder's Association. The Home Builder's had two primary concerns: one dealt with the ~quare footage of impervious cover that would be exempted under the provisions which were originally recommended, or 10,000 square feet. The Blue Ridge Home Builder's asked that this be increased to 40,000 square feet. Mr. Bailey, County Engineer, at a Planning CommissiOn meeting, said he felt that without any detrimental effect to the environment, this square footage could be increased to 20,000 square feet, and that change was made and is recommended to the Board. Mr. Tucker said other changes were made by the Planning Commission at their hearing, (shown in italics in the following recommendations), and the~ recommended approval of these ordinances with changes by a 7-1-1 vote. 17-5-13 a~-e~¢-e~e-eh~-~e-~e~&~e~ (a) Provisions shall be made for the disposition of surface water ~unoff from the site, inclUding such on-site and off-site drainage faciIities as the Commi.ssion, upon the recommendation of the County~2Engineer, may
