Context The Northwest Residential Area is situated at the north end of the North Pointe development and is to be accessed by an extension of Lewis & Clark Drive. The entrance to the University of Virginia Research Park is across Rt. 29 to the west. A mix of residential development lies to the east. A mix of commercial, industrial and residential development extends north and south along Rt. 29. The North Pointe stormwater facilities previously reviewed by the ARB are located at the north and south ends of this phase of development. Visibility The proposed townhouse development will be visible from the Route 29 Entrance Corridor. Topography will allow the upper parts of some townhouses to be visible above units located at lower elevations. Existing vegetation to remain and, eventually, additional trees planted throughout t he development, will reduce some visibility. ARB Meeting Date December 3, 2018 Staff Contact Margaret Maliszewski 2 PROJECT HISTORY An application with the same project name was reviewed and approved by the ARB in 2017. Subsequently, the applicant desired a revised layout, so a new initial site plan was submitted and reviewed by the ARB on April 2, 2018. The application that is the subject of this report is a final site plan following the April 2, 2018 initial plan. DATE APPLICATION RESULT 4-2-2018 ARB-2018-30 The ARB reviewed an Initial Site Plan showing a revised layout for the Northwest Residential Area development. (See Attachment A for the action letter.) 8-1-2017 ARB-2017-39 Certificate of Appropriateness issued, with conditions, for the Northwest Residential Area development. 2-6-2017 ARB-2016-160 The ARB completed a preliminary review and provided a number of comments on the proposed Northwest Residential Area development. 10-14-2016 SUB-2016-196 Road plans for the Northwest Residential Area submitted for review. 4-18-2011 ARB-2011-27 The ARB completed a preliminary review of the Northwest Residential Area site plan. 4-1-2011 ARB-2011-10 A Certificate of Appropriateness was issued for stormwater management facilities #10 and #11. No final engineering approval was granted for these facilities. 2-14-2007 SP-2006-34 A Special Use Permit for a stream crossing was approved. 12-18-2006 ARB-2006-129 The ARB provided advisory comments on the Special Use Permit application for the stream crossing. 4-19-2004 ARB-2004-26 The ARB completed an advisory review for the North Pointe rezoning. ANALYSIS This table outlines the issues and recommendations made during the 4/2/2018 review of the initial site plan, with current analysis and recommendations on the current (final) plan. REF GUIDELINE 4/2/2018 ISSUE 4/2/2018 RECOMMENDATION CURRENT ISSUE CURRENT RECOMMENDATION Structure design 1 The goal of the regulation of the design of development within the designated Entrance Corridors is to insure that new development within the corridors reflects the traditional architecture of the area. Therefore, it is the purpose of ARB review and of these Guidelines, that proposed development within the designated Entrance Corridors reflect elements of design characteristic of the significant historical landmarks, buildings, and structures of the Charlottesville and Albemarle area, and to promote orderly and attractive development within these corridors. Applicants should note that replication of historic structures is neither required nor desired. Architectural designs were not submitted with the initial site plan. However, it is anticipated that the townhouse designs will incorporate forms and features that are typically found in historic residential architecture, like pediments and gables, without making a strong connection to local historic resources. If rear and side elevations of the townhouses will face the EC, they will need to include Submit architectural designs for review with the final site plan. Include sufficient architectural features and detailing on all building elevations facing the EC to achieve an appropriate appearance for the EC. Architectural elevations for Blocks 1, 3 and 10 have been submitted, with Blocks 4, 5, 7, 14, 15, 16, 18, 19, 21 and 24 noted as “similar”. Most of the townhouse blocks facing the EC are not listed by number on the elevation drawings. Elevations are needed for all the townhouse blocks so the overall visual impact of the development can be assessed. The submitted elevations are similar to those that were approved with ARB-2017- 39, but some have a reduced level of detail. They incorporate forms and features that are typically found in historic residential Revise the elevation drawings to include notes indicating that 1) a maximum of two adjacent facades shall be co- planar, 2) adjacent townhouses shall not have the same siding color, and 3) two townhouses having full brick facades shall not be adjacent. Add sill courses below the second story windows 3 2 Visitors to the significant historical sites in the Charlottesville and Albemarle area experience these sites as ensembles of buildings, land, and vegetation. In order to accomplish the integration of buildings, land, and vegetation characteristic of these sites, the Guidelines require attention to four primary factors: compatibility with significant historic sites in the area; the character of the Entrance Corridor; site development and layout; and landscaping. sufficient architectural features and detailing to achieve an appropriate appearance for the EC. architecture, like pediments and gables, without making a strong connection to local historic resources. Compared to previous designs, the sill courses below the second story windows are missing, as are the hoods over the ground story entrances and some detailing at window heads. The entrances on the rear elevations are sliding glass doors. This emphasizes that the elevation is the rear of the building. The addition of decks (or other features typically found in backyards) to these EC-facing elevations would further emphasize that these elevations are the backs of the townhouses. The townhouse blocks range from 3 units to 7 units long. To limit the visual impacts of the mass of the blocks, the conditions of approval outlined with the 2017 plan should remain. Materials and colors are consistent with the 2017 designs and include Hardi-Plank in khaki brown and darker shades of brown, blue, green, and gray; shutters in similar shades; General Shale Buckingham Tudor brick; light oak stain for doors, and Timberline charcoal grey architectural grade shingles for roofs. The colors and materials are expected to have an appropriate appearance for the EC. Side elevations have two windows at the upper stories and one at the ground level. There is also a material change above the first floor and a pediment at the roof with a on elevations facing Rt. 29. Provide elevations for all townhouse blocks. 3 New structures and substantial additions to existing structures should respect the traditions of the architecture of historically significant buildings in the Charlottesville and Albemarle area. Photographs of historic buildings in the area, as well as drawings of architectural features, which provide important examples of this tradition are contained in Appendix A. 4 The examples contained in Appendix A should be used as a guide for building design: the standard of compatibility with the area’s historic structures is not intended to impose a rigid design solution for new development. Replication of the design of the important historic sites in the area is neither intended nor desired. The Guideline’s standard of compatibility can be met through building scale, materials, and forms which may be embodied in architecture which is contemporary as well as traditional. The Guidelines allow individuality in design to accommodate varying tastes as well as special functional requirements. 9 Building forms and features, including roofs, windows, doors, materials, colors and textures should be compatible with the forms and features of the significant historic buildings in the area, exemplified by (but not limited to) the buildings described in Appendix A [of the design guidelines]. The standard of compatibility can be Architectural designs were not submitted with the initial site plan. A full review will be completed when the designs are submitted with the final site plan. In the previous application, some of the rear elevations had Provide architectural elevations for review. A maximum of two adjacent facades shall be co-planar. 4 met through scale, materials, and forms which may be embodied in architecture which is contemporary as well as traditional. The replication of important historic sites in Albemarle County is not the objective of these guidelines. elements and/or details (such as patio doors) that marked them visually as rear elevations. To help reduce blankness and massiveness, the previous approval was granted with the following conditions (see Attachment A): 1) A maximum of two adjacent facades shall be co- planar. 2) Adjacent townhouses shall not have the same siding color. 3) Two townhouses having full brick facades shall not be adjacent. Given the revised layout, these conditions also seem appropriate for the current plan. Adjacent townhouses shall not have the same siding color. Two townhouses having full brick facades shall not be adjacent. vent. This appears to be sufficient detail for the side elevations. 11 The overall design of buildings should have human scale. Scale should be integral to the building and site design. Within individual townhouse blocks, the material and color changes, and the stepping forward and back of the units within each block help establish human scale. Overall, the block divisions and landscaping can help mitigate the scale of the larger development as viewed from the EC street. None. 12 Architecture proposed within the Entrance Corridor should use forms, shapes, scale, and materials to create a cohesive whole. There is sufficient repetition of architectural details, materials and colors to establish a cohesive appearance for the overall development. None. 13 Any appearance of “blankness” resulting from building design should be relieved using design detail or vegetation, or both. Blankness is not a characteristic of the townhouse design. None. 14 Arcades, colonnades, or other architectural connecting devices should be used to unify groups of buildings within a development. The townhouse blocks are unified in their use of consistent architectural details, materials and colors. None. 15 Trademark buildings and related features should be modified to meet the requirements of the Guidelines. The townhouses do not have the look of trademark designs, although the designs may be constructed in other locations. None. 16 Window glass in the Entrance Corridors should not be highly tinted or highly reflective. Window glass in the Entrance Corridors should meet the following criteria: Visible light transmittance (VLT) shall not drop below 40%. Visible light reflectance (VLR) shall not exceed 30%. Specifications on the proposed window glass should be submitted with the application for final review. Given the distance from the EC street and the wooded area between the street and the development, the tint and reflectivity of the window glass is not expected to have a significant impact on the EC. None. Given the distance from the EC street and the wooded area between the street and the development, the tint and reflectivity of the window glass is not expected to have a significant impact on the EC. None. Compatibility with the character of the Entrance Corridor 5 It is also an important objective of the Guidelines to establish a pattern of compatible architectural The existing wooded area to remain along the EC frontage See recommendations above. The proposed development will be compatible with other existing residential See other recommendations, above 5 characteristics throughout the Entrance Corridor in order to achieve unity and coherence. Building designs should demonstrate sensitivity to other nearby structures within the Entrance Corridor. Where a designated corridor is substantially developed, these Guidelines require striking a careful balance between harmonizing new development with the existing character of the corridor and achieving compatibility with the significant historic sites in the area. will help buffer the development as viewed from the EC street. This effect will be strengthened over time as street trees throughout the development mature. If the townhouse design is similar to what was previously proposed, the development will not appear unlike other existing residential developments along the corridor, but without a strong, positive connection to the historic architecture of the county. developments along the corridor, but without a strong, positive connection to the historic architecture of the county. and below. 10 Buildings should relate to their site and the surrounding context of buildings. Accessory structures and equipment 17 Accessory structures and equipment should be integrated into the overall plan of development and shall, to the extent possible, be compatible with the building designs used on the site. The townhouses along Lewis & Clark Drive have their backs oriented towards the EC. It is anticipated that residential scale mechanical equipment and trash containers will be located in the back yards. These items are expected to be relatively small, and visibility will be somewhat limited by distance and wooded area, but no screening is shown. Security fencing at the stormwater management facilities is 42” high Ameristar black fencing, which was previously approved. It is expected to have an appropriate appearance for the EC. The mechanical equipment note will be needed on both the site plan and the architectural plans. Add to following note the site plan and the architectural plan: “Visibility of all mechanical equipment from the Entrance Corridor shall be eliminated.” The plan shows mechanical units along the side elevations of the townhouse blocks, at the far end of the blocks as viewed from the EC. Low-growing shrubs are proposed along the far side of Lewis & Clark (as viewed from the EC). At mature height, these shrubs would likely be shorter than the mechanical equipment. Other landscaping and wooded area to remain between the townhouses and the street, combined with the distance from the EC, are expected to mitigate views of the equipment. None. 18 The following should be located to eliminate visibility from the Entrance Corridor street. If, after appropriate siting, these features will still have a negative visual impact on the Entrance Corridor street, screening should be provided to eliminate visibility. a. Loading areas, b. Service areas, c. Refuse areas, d. Storage areas, e. Mechanical equipment, f. Above-ground utilities, and g. Chain link fence, barbed wire, razor wire, and similar security fencing devices. None. 19 Screening devices should be compatible with the design of the buildings and surrounding natural vegetation and may consist of: a. Walls, b. Plantings, and c. Fencing. None. 21 The following note should be added to the site plan and the architectural plan: “Visibility of all mechanical equipment from the Entrance Corridor shall be eliminated.” The equipment note appears on the architectural elevations sheets and the site plan. None. 6 Lighting No lighting is proposed. None at this time. No lighting is proposed. None at this time. Landscaping Landscaping was not included in the Initial Plan. Landscaping requirements associated with previous SP and ZMA approvals (see Attachments B and C), in addition to EC landscaping guidelines, will need to be met. Include with the final site plan a landscape plan that addresses the requirement for the 40’ landscape buffer along the EC frontage of the development. Provide landscaping at the entrance to the development to establish an appropriate appearance for the EC. A 40’ landscape buffer is required along the Rt. 29 frontage. The previously approved plan showed the buffer and indicated the existing wooded area that would remain in the buffer. Sheet 9 of the current landscape plan includes notes identifying the 40’ landscape buffer in the vicinity of the entrance to the development, but the full Rt. 29 frontage is not shown on the plan. Although the alignment of the extension of Lewis & Clark Drive has changed, the landscaping proposed at the entrance from Rt. 29 is generally consistent with the previous approval and is expected to have an appropriate appearance. Two trees are located over sewer laterals. One is north of unit 47; the other is north of unit 109. Some of the quantities in the plant schedule appear to be inaccurate, including the abelia and the linden tree (TCG), which is also illustrated with two different symbols. Revise the landscape plan to address the requirement for the 40’ landscape buffer along the EC frontage of the development and show how the buffer is coordinated with existing wooded area to remain and proposed frontage improvements. Resolve the tree and sewer lateral conflicts near units 47 and 109. Coordinate the quantities of linden and abelia drawn on the plan with the quantities listed in the plant schedule. Use a single symbol for the TCG plant. 7 The requirements of the Guidelines regarding landscaping are intended to reflect the landscaping characteristic of many of the area’s significant historic sites which is characterized by large shade trees and lawns. Landscaping should promote visual order within the Entrance Corridor and help to integrate buildings into the existing environment of the corridor. 8 Continuity within the Entrance Corridor should be obtained by planting different types of plant materials that share similar characteristics. Such common elements allow for more flexibility in the design of structures because common landscape features will help to harmonize the appearance of development as seen from the street upon which the Corridor is centered. 32 Landscaping along the frontage of Entrance Corridor streets should include the following: a. Large shade trees should be planted parallel to the Entrance Corridor Street. Such trees should be at least 3½ inches caliper (measured 6 inches above the ground) and should be of a plant species common to the area. Such trees should be located at least every 35 feet on center. b. Flowering ornamental trees of a species common to the area should be interspersed among the trees required by the preceding paragraph. The ornamental trees need not alternate one for one with the large shade trees. They may be planted among the large shade trees in a less regular spacing pattern. c. In situations where appropriate, a three or four board fence or low stone wall, typical of the area, should align the frontage of the Entrance Corridor street. d. An area of sufficient width to accommodate the Flood plain, open space and wooded area extend along the EC frontage of this development. A 40’ landscape buffer is required along the frontage. The previous application included a plan showing the buffer and indicating that existing wooded area would remain in the buffer; no new planting was proposed. At a minimum, this site plan should include the same information. The landscape plan approved with the previous application showed a considerable amount of planting at the entrance to the development from Rt. 29. The landscape plan for this 7 foregoing plantings and fencing should be reserved parallel to the Entrance Corridor street, and exclusive of road right-of-way and utility easements. application should show planting of equivalent quantity and character. 33 Landscaping along interior roads: a. Large trees should be planted parallel to all interior roads. Such trees should be at least 2½ inches caliper (measured six inches above the ground) and should be of a plant species common to the area. Such trees should be located at least every 40 feet on center. A note on the cover sheet states that street trees will be planted every 40’ along roadways. Some drainage pipes, water and sewer lines may need to be shifted to allow for consistent tree spacing. Arrange utilities to allow for street trees consistently spaced 40’ on center along interior roads. Special Use Permit conditions require large shade trees on the north and south sides of Lewis & Clark Drive, 2½” at planting, 40’ on center for a distance of 400’. Large trees are provided at the specified size, but only 8 are provided, rather than the 10 required, on both sides of the road. Special Use Permit conditions require a mixed planting of large, medium, and small deciduous trees ranging from 1½” to 2½” caliper and evergreen trees ranging from 4’ to 6’ in height in the median. The 4’-6’ evergreens are not provided. A landscape maintenance agreement is required for this planting. Add 2 large shade trees, 2½” caliper at planting, on both sides of Lewis & Clark Drive, (for a total of 4 trees) within 400’ of the Rt. 29 intersection. Add 4’-6’ evergreen trees in the mixed median planting. Provide a landscape maintenance agreement for the median plants. 34 Landscaping along interior pedestrian ways: a. Medium trees should be planted parallel to all interior pedestrian ways. Such trees should be at least 2½ inches caliper (measured six inches above the ground) and should be of a species common to the area. Such trees should be located at least every 25 feet on center. Sidewalks are provided along most of the interior roads where trees are required at 40’ on center. None at this time. Sidewalks are provided along many of the interior roads where trees are required at 40’ on center. 35 Landscaping of parking areas: a. Large trees should align the perimeter of parking areas, located 40 feet on center. Trees should be planted in the interior of parking areas at the rate of one tree for every 10 parking spaces provided and should be evenly distributed throughout the interior of the parking area. b. Trees required by the preceding paragraph should measure 2½ inches caliper (measured six inches above the ground); should be evenly spaced; and should be of a species common to the The proposal includes two groups of five parking spaces where this guideline would apply. One is at the northeast corner of the development; the other is at the southeast corner. None at this time. There are 3 parking lots proposed (as well as on-street parking). The lots contain 4, 10 and 14 parking spaces in single rows. There are no interior trees in these rows, but perimeter trees are provided. The 4-space lot and a pair of parking spaces have been added near the entrance to the development, northeast of Block 1. Eastern red cedars are proposed nearby. None. 8 area. Such trees should be planted in planters or medians sufficiently large to maintain the health of the tree and shall be protected by curbing. c. Shrubs should be provided as necessary to minimize the parking area’s impact on Entrance Corridor streets. Shrubs should measure 24 inches in height. 36 Landscaping of buildings and other structures: a. Trees or other vegetation should be planted along the front of long buildings as necessary to soften the appearance of exterior walls. The spacing, size, and type of such trees or vegetation should be determined by the length, height, and blankness of such walls. b. Shrubs should be used to integrate the site, buildings, and other structures; dumpsters, accessory buildings and structures; “drive thru” windows; service areas; and signs. Shrubs should measure at least 24 inches in height. Architectural designs have not yet been submitted for review. None at this time. Rear elevations of the townhouses face the EC. Layers of landscaping are proposed to help mitigate the appearance of the rear elevations. These include street trees along both sides of Lewis & Clark Drive, and a mix of deciduous and evergreen trees between the drive and open space/wooded area to remain. The mix includes oaks and elms, Virginia pine, Sweetbay magnolia, and Eastern red cedar. Many of the groups of Virginia pine and Sweetbay magnolia have been placed without considering the location of the retaining wall (see sheet 10). A row of shrubs is proposed along the townhouse side of Lewis & Clark Drive. The shrubs are a mix of St. John’s wort and Dwarf Hydrangea. Both are proposed at 24” high at planting, but the St. John’s wort typically only grows to 1.5’ tall and the hydrangea to 2’-3’ tall. The plants are located on the townhouse lots. They should be located outside the individual lots, in areas maintained by the homeowner’s association. A row of shrubs (Otto Luyken cherry laurel) is proposed behind townhouse blocks 4 and 5, but the plants are located on the individual townhouse lots. They should be located outside the individual lots, in areas Shift the locations of the groups of Virginia pine and Sweetbay magnolia to coordinate with the retaining wall location. Shift landscaping from individual lots to areas under the control of the homeowners’ association. Revise the species of shrubs proposed along Lewis & Clark Drive to ones that can easily be acquired at 24” planting height. 9 maintained by the homeowner’s association. 37 Plant species: a. Plant species required should be as approved by the Staff based upon but not limited to the Generic Landscape Plan Recommended Species List and Native Plants for Virginia Landscapes (Appendix D). This guideline will be reviewed when the landscape plan is submitted with the final site plan. None at this time. The proposed plants appear on the various lists. None. 38 Plant health: The following note should be added to the landscape plan: “All site plantings of trees and shrubs shall be allowed to reach, and be maintained at, mature height; the topping of trees is prohibited. Shrubs and trees shall be pruned minimally and only to support the overall health of the plant.” The note will be needed on the landscape plan. Add the standard plant health note to the plan. The note appears on sheet 10A. None. Site Development and layout 6 Site development should be sensitive to the existing natural landscape and should contribute to the creation of an organized development plan. This may be accomplished, to the extent practical, by preserving the trees and rolling terrain typical of the area; planting new trees along streets and pedestrian ways and choosing species that reflect native forest elements; insuring that any grading will blend into the surrounding topography thereby creating a continuous landscape; preserving, to the extent practical, existing significant river and stream valleys which may be located on the site and integrating these features into the design of surrounding development; and limiting the building mass and height to a scale that does not overpower the natural settings of the site, or the Entrance Corridor. The revised site layout places the new extension of Lewis & Clark Drive (the main road into the development) a bit further west/southwest (closer to the EC) than the previous plan, and all of the residential units are now located on the far side of the road as viewed from the EC. A sidewalk is provided along Lewis & Clark Drive, but no connections are provided from that sidewalk to individual residential units, suggesting that the backs of the units face the EC. Flood plain, open space and wooded area occupy the area between the extended Lewis & Clark Drive and the EC. The residential blocks are group of 5 and 6 units along the full length of the Drive starting approximately 150’ from the EC. Show how the side and rear townhouse elevations will have an appropriate appearance for the EC. Twelve townhouse blocks are located along the far side of Lewis & Clark Drive, as viewed from the EC. (Rear elevations face the drive.) Steps are now shown at ten of these blocks connecting the sidewalk to the townhouses. Blocks 30 and 31 have no connection to the sidewalk. Landscaping has been increased between the sidewalk and these two blocks. See #1 for information regarding the side and rear elevations. See #1. 39 The relationship of buildings and other structures to the Entrance Corridor street and to other development within the corridor should be as follows: a. An organized pattern of roads, service lanes, bike paths, and pedestrian walks should guide the 10 layout of the site. b. In general, buildings fronting the Entrance Corridor street should be parallel to the street. Building groupings should be arranged to parallel the Entrance Corridor street. c. Provisions should be made for connections to adjacent pedestrian and vehicular circulation systems. d. Open spaces should be tied into surrounding areas to provide continuity within the Entrance Corridor. e. If significant natural features exist on the site (including creek valleys, steep slopes, significant trees or rock outcroppings), to the extent practical, then such natural features should be reflected in the site layout. If the provisions of Section 32.5.2.n of the Albemarle County Zoning Ordinance apply, then improvements required by that section should be located so as to maximize the use of existing features in screening such improvements from Entrance Corridor streets. f. The placement of structures on the site should respect existing views and vistas on and around the site. Blocks at the interior of the development are set more or less perpendicular to the blocks along Lewis & Clark Drive. No buildings directly front the EC street and the proposed buildings are not oriented parallel to the street. Distant views are not currently available across this property due to the wooded character of the site. However, because a significant amount of wooded area will be removed to accommodate the development, the view along the corridor will change considerably. Site Grading 40 Site grading should maintain the basic relationship of the site to surrounding conditions by limiting the use of retaining walls and by shaping the terrain through the use of smooth, rounded land forms that blend with the existing terrain. Steep cut or fill sections are generally unacceptable. Proposed contours on the grading plan shall be rounded with a ten foot minimum radius where they meet the adjacent condition. Final grading should achieve a natural, rather than engineered, appearance. Retaining walls 6 feet in height and taller, when necessary, shall be terraced and planted to blend with the landscape. Significant grading will be needed to construct this development. The flood plain and some of the wooded area adjacent to the EC will remain and maintain the current relationship to the street. The design of the stormwater facility located at the north end of the development does not appear to have changed since the previous review. Three tiered 6’-tall retaining walls are still proposed None at this time. The applicant’s cover letter states that the project was redesigned to reduce the amount of land disturbance and earth moving operations across the site, stepping the buildings up across the terrain and reducing redundant utilities. Still, significant grading and extensive retaining walls are proposed to accomplish the development. Planting is proposed at stormwater management facility “B”, at the north end of the development. The grading plan shows geo-grid behind the retaining wall system, Confirm with Anchor block, and provide documentation, that 3’ is sufficient spacing between large trees and the retaining wall where geo-grid is used. Otherwise, increase planting area to accommodate the trees. Revise the plan to show landscaping at the 11 20 Surface runoff structures and detention ponds should be designed to fit into the natural topography to avoid the need for screening. When visible from the Entrance Corridor street, these features must be fully integrated into the landscape. They should not have the appearance of engineered features. there. The facility at the south end is now shown with a single retaining wall with a maximum height of 2’. This is considerably less retaining wall than was in the previous design. Notes indicate that the proposed wall material is Anchor Diamond Pro Segmented block in tan for both facilities. This is the same block as was approved for the previous application. Landscaping consistent with the previous plan will still be required. with large trees spaced 3’-5’ from the wall. Some wall systems recommend a greater distance (10’) where geo-grid is present. Landscaping previously shown at the stormwater facility located at the south end of the project area has been removed from the plan. Landscaping is needed to integrate the facility into the surroundings. stormwater facility located at the south end of the project area consistent with the previous approval. 44 Natural drainage patterns (or to the extent required, new drainage patterns) should be incorporated into the finished site to the extent possible. 41 No grading, trenching, or tunneling should occur within the drip line of any trees or other existing features designated for preservation in the final Certificate of Appropriateness. Adequate tree protection fencing should be shown on, and coordinated throughout, the grading, landscaping and erosion and sediment control plans. Existing wooded area to remain and tree protection fencing will need to be shown clearly throughout the site plan. Revise the plan to clearly show existing wooded area to remain and tree protection fencing throughout the site plan. Limits of disturbance, tree protection, and protected wooded area are shown on the plan. None. 42 Areas designated for preservation in the final Certificate of Appropriateness should be clearly delineated and protected on the site prior to any grading activity on the site. This protection should remain in place until completion of the development of the site. 43 Preservation areas should be protected from storage or movement of heavy equipment within this area. 12 SUMMARY OF RECOMMENDATIONS Staff recommends the following as the primary points of discussion: 1. The revised site layout 2. The architectural design of the townhouses; the rear elevations facing the EC 3. Proposed landscaping; quantity, character, location Staff recommends approval with the following revisions: 1. Revise the elevation drawings to include notes indicating that 1) a maximum of two adjacent facades shall be co -planar, 2) adjacent townhouses shall not have the same siding color, and 3) two townhouses having full brick facades shall not be adjacent. 2. Add sill courses below the second story windows on elevations facing Rt. 29. 3. Provide elevations for all townhouse blocks. 4. Revise the landscape plan to address the requirement for the 40’ landscape buffer along the EC frontage of the development and show how the buffer is coordinated with existing wooded area to remain and proposed frontage improvements. 5.

Use a single symbol for the TCG plant. 7. Add 2 large shade trees, 2½” caliper at planting, on both sides of Lewis & Clark Drive, (for a total of 4 trees) within 400’ of the Rt. 29 intersection. 8. Add 4’-6’ evergreen trees in the mixed median planting. 9. Provide a landscape maintenance agreement for the median plants. 10. Shift the locations of the groups of Virginia pine and Sweetbay magnolia to coordinate with the retaining wall location. 11. Shift landscaping from individual lots to areas under the control of the homeowners’ association. 12. Revise the species of shrubs proposed along Lewis & Clark Drive to ones that can easily be acquired at 24” planting height. 13. Confirm with Anchor block, and provide documentation, that 3’ is sufficient spacing between large trees and the retaining wall where geo-grid is used. Otherwise, increase planting area to accommodate the trees. 14. Revise the plan to show landscaping at the stormwater facility located at the south end of the project area consistent with the previous approval. 13 TABLE A This report is based on the following submittal items: Sheet # Drawing Name Drawing Date 1 Cover 10/22/2018 2 Existing Conditions 10/22/2018 3 Layout Plan 10/22/2018 4 Layout Plan 10/22/2018 5 Utility Plan 10/22/2018 6 Utility Plan 10/22/2018 7 Grading & Drainage Plan 10/22/2018 8 Grading & Drainage Plan 10/22/2018 9 Landscaping Plan 10/22/2018 10 Landscaping Plan 10/22/2018 11 Landscaping Notes & Details 10/22/2018 12 Site Section Map 10/22/2018 13 Site Sections 10/22/2018 3 Land Use Plan & Map Key 7/12/2017 1 of 1 Layout Exhibit 10/16/2018 A1 Exterior Elevations – 20’ wide slab w/ front garage 3/3/2017 A2 Exterior Elevations – 20’ wide walk-out basement 3/3/2017 A4 Exterior Elevations - 20’ wide slab (garage optional) 3/3/2017 - Rt. 29 Improvements Typical Street Section - 14 ATTACHMENT A 15 ATTACHMENT B 16 ATTACHMENT C
