ARB Meeting Date September 4, 2018 Staff Contact Heather McMahon ' ' 0a1BE"811K'sto]:7'1 DATE APPLICATION RESULT 10/1/2014 ZMA-2013-16 Request to rezone 11.886 acres from R1 to PRD approved. Design Planning staff comments were provided during the review of the rezoning. The character and appearance of the stormwater facility and landscaping along the EC frontage were identified as primary issues. 3/21/2016 ARB-2015-120 ARB approved an Amendment to the townhome designs in Avinity Estates I 1/8/2018 ARB-2017-94 ARB reviewed the Initial Site Development Plan for Avinity Estates 1/16/2018 ARB-2017-94 ARB held a work session for the Initial Site Development Plan, specifically focusing on the general layout and the cul-de-sac on the southeastern end of the site, as well as the proposed stormwater management facility and its landscaping. The board forwarded a recommendation of approval with conditions to be met in future submissions to the agent of the Site Review Committee (See Attachments A and B). 9/4/2018 ARB-2018-108 ARB will review the Final Site Development Plan for Avinity Estates for the first time This proposal is an extension of the original Avinity development that fronts Avon Street Extended and was reviewed and approved between 2007 and 2010. In November 2014, a Zoning Map Amendment (ZMA-2013-16) to rezone 11.886 acres between the Avinity I development and Route 20 (Scottsville Road) was approved. This development proposes 51 single-family attached units, 51 townhouse units, and a clubhouse as well as associated improvements. The proposed development will have access to Route 20 as well as Avinity 1. VISIBILITY The project area abuts the EC street (Route 20 South) in two places: 1) a pipe stem which holds an emergency access road north of the Kappa Sigma Headquarters property, and 2) 0.87 acres of open space with approximately 260' of frontage to the south of Kappa Sigma that includes one of two proposed stormwater management facilities. Both will be visible from the EC. The topography of the L-shaped site rises steeply westward [Figure 1]; therefore, the roofs, sides, and upper portions of the three-story townhouse units in the interior lots will be visible over the rooflines of those two-story single-family attached units adjacent to the eastern perimeter of the site, behind the Kappa Sigma property. For instance, the FFE at the EC is 490 while the FFE at lot 41, closest to the EC, is 526 and rises to an apex of FFE 568 at lot 24, at the western end of the site. Therefore, the roofs of lots 83-86 (with FFEs of 554 to 556) will be seen over lots 42-48 (with FFEs of 532 to 549) to the east, while townhouses on lots 87-102 may be seen incrementally through the single-family attached unit lots 49-61, as their FFEs are commensurate. Lots 14-17 (FFE 568) will rise above lots 78-87 and lots 42-48. Large portions of the rear (north) elevations of lots 42-48 may be visible from the southbound lane of the EC; the side (east) elevation of 41 is the closest to the EC and will be visible; the majority of the front (south) elevations of lots 42-44 may be visible at the intersection of Route 20 with Pebble Drive; and the side (east) elevation of lot 42 will be visible. The rear elevations of lots 49-61 and possibly the (east) side elevation of the proposed clubhouse will be visible from the EC through the Kappa Sigma property, despite a single row of tree planting and fencing. Figure 1: The property in question rises steeply westward, suggesting that the majority of the proposed dwellings will be visible from the EC. As seen from Route 20 North, an Entrance Corridor.

The latter will serve as screening of the stormwater management facility in this corner of the site. Additional tree plantings to the west of this stand and the stormwater management facility will help integrate the development with the context. Furthermore, the applicant is proposing sufficient street trees throughout the development. This submission has revised the east -west interior street (Moffat) in the southern portion of the site to terminate in one small cul-de-sac in the southwest corner and a larger cul-de-sac in the southeast corner of the site. There are no proposed buildings that have rear elevations facing the EC in this part of the site, although those abutting and behind the Kappa Sigma property (lots 49-61) on the eastern perimeter are oriented with their backs turned to Route 20. The single row of trees (alternating red oaks and little gem magnolias) on the eastern boundary of the site, and the 8-foot-tall wooden privacy fence, will reduce visibility but will not completely screen the rear elevations from the EC.

Given the topography, the retaining walls will be visible from the EC (for instance, the EC is at 490 FFE, while the tops of the walls on the north retention pond are 11 504 and 512 and the tops of the walls on the southeast retention pond are 504 and 514). Sheet 3B describes the southeast stormwater management facility retaining walls as consisting of Eagle Bay "Diamond Pro" block, color `James River.' This material has been previously approved by the ARB, and a sample has been provided for review: the color is appropriate for the EC. Furthermore, the proposed plantings between the walls will largely obscure them once the shrubs reach maturity. The southeastern stormwater management facility has been greatly reduced in size and has been revised to have a less -engineered appearance (more naturalistic curvature) since the previous submission. The north stormwater management facility, which is located approximately 760 feet due west of the EC, also has a naturalistic form. Both have been sufficiently landscaped, and the extant treeline on the southeastern corner of the site will be retained for additional screening. The access road to the southeastern stormwater management facility has been revised so that the majority of it lies to the south of the retention pond, although the end of the road does approach the pond's southeastern edge. However, the road has been sufficiently screened with a row of hollies and a row eastern red cedars. The overhead power line and easement in the southeastern corner of the site has been illustrated on the site plan, and no landscaping is proposed within the easement. Other 12 utilities (such as underground water, sewer, and stormwater), however, have not been illustrated on the landscape plans.

Visibility of the development from the EC; architectural drawings required for the next submittal. 2. Treatment of the stormwater management facility adjacent to the EC. Staff recommends approval with the following conditions: 1. Consider creating a larger planting area between the rear lot lines and proposed privacy fence and the property line abutting the Kappa Sigma parcel in order to accommodate more planting. 2. Add the standard window glass note to the Arch D-sized elevation drawings: Window glass in the Entrance Corridors should meet the following criteria: Visible light transmittance (VLT) shall not drop below 4001o. Visible light reflectance (VLR) shall not exceed 30% Specifications on the proposed window glass should be submitted with the application for final review. 3. Provide details of each proposed fence in the plan, noting materials and colors. Provide material/color samples. 4. Provide the standard mechanical equipment note on the architectural elevations: Visibility of all mechanical equipment from the Entrance Corridor shall be eliminated. 5. Include the standard lighting note on the cover sheet: Each outdoor luminaire equipped with a lamp that emits 3,000 or more initial lumens shall be a full cutoff luminaire and shall be arranged or shielded to reflect light away from adjoining residential districts and away from adjacent roads. The spillover of lighting from luminaires onto public roads and property in residential or rural areas zoning districts shall not exceed one half footcandle. 6. Create a more naturalistic vegetative cover around the SWMF by integrating evergreens, large and medium deciduous trees, and shrubs in a naturalistic pattern. 7. Ensure that street trees are planted a minimum of 7 feet from the center of a water or sewer line without decreasing quantity of trees provided. 8. Provide additional street trees to reduce the on center planting gaps larger than 50 feet on center. 9. It is recommended that the trees along Pebble Drive be located in a 10' wide easement maintained by the HOA, and that the trees be located on the Pebble Drive side of the fence. 10. Rectify the quantity error for MV in the plant schedule on Sheet 7. Reduce the quantity of CK and IV by 7 each while maintaining all other plant quantities at 25% or less. 11. Show how the retaining wall, fence and trees can be accommodated at the southeast corner of Lot 41.
