Zoned Neighborhood Model District (NMD)/Entrance Corridor (EC) Owner/Applicant Crockett Corporation/Bohler Engineering (Ryan Yauger) Magisterial District Rivanna Proposal To develop block 8A with an assisted living facility — a four -floor building encompassing 232,956 square feet and containing 179 units — as well as access drives, throats, and stub -outs on 5.57 acres. Context and Visibility Block 8A lies adjacent to and immediately east of Rt. 29, an EC [Figure 1]. Visibility is mitigated by an existing tree line. Parcels to the west and south are rural in character, while parcels to the north and east are developed as the residential communities of Forest Lakes and Montgomery Ridge. ARB Meeting Date March 18, 2019 Staff Contact Heather McMahon PROJECT HISTORY DATE APPLICATION/REVIEW TYPE RESULT 10/2/2017 ARB-2017-81: Brookhill, Blocks 4A and 8A, Initial The ARB recommended approval to the Site Agent with one condition 3/18/2019 ARB-2019-81: Brookhill, Block 8A, Initial The ARB will review this application for the first time The ARB first reviewed the proposed site design for the north and east perimeters of Block 8A in conjunction with the initial site plan of Block 4A in October 2017. At that time, the proposal was to partially develop Block 8A with access drives, throats, and stub -outs that would feed into the southern portion of Block 4A and to the new road connecting to Polo Grounds Road. The ARB approved the final site plan for Blocks 4A and 4B in August 2018. Figure 1: map showing TMPs 46-19A (Brookhill Block 8A). This and adjacent parcels are zoned Neighborhood Model District (NMD) BACKGROUND The parcels comprising the Brookhill development have been zoned Neighborhood Model District (NMD), which requires a Code of Development. The approved Code of Development [Figure 2] identifies this subsection of Block 8, on the southwest corner of the site, as "Neighborhood Density" in the north with greenspace (an existing 100-year FEMA floodplain) in the south. The Code of Development also requires a 100-foot tree buffer along Rt. 29 that will screen the western boundary of the block and mitigate visibility of the proposed building from Rt. 29, the Entrance Corridor under consideration, as well as a 30-foot landscape buffer along Polo Grounds Road. [Figure 3] As this is an initial site plan, however, no architectural elevations have been submitted for review.

Additionally, the southern portion of Block 8A (approximately 12 acres) will be preserved as greenspace, which will also help mitigate visibility of the proposed assisted living facility and integrate the development into the rural character of the area. The building is located in the center of the site, with a setback over 100' from the western (rear) property line (along the EC), 65' from the eastern (front) property line, and 68' from the north (side) property line. The layout is fundamentally a building surrounded by asphalt travelways and perimeter parking. This layout contradicts the principles of NMD, which desires walkable, pedestrian -oriented development closer to the property lines.

Besides those two species, all others proposed for the landscape buffers and the interior of the block are not only natives, but are indigenous to this region, which is exceptional. The 12-acre southern portion of Block 8A is proposed to be preserved as greenspace. Although no development is proposed, the 70-foot undisturbed section and the 30-foot disturbed section of the frontage buffer still need to be (re -)forested, especially as the extant treeline does not extend through the 100-foot depth. Therefore, the reforesting of this buffer needs to be shown on this site plan to meet the Code of Development requirements.

The westernmost is closest to the EC, but shrubs and trees planted within the 100-foot landscape buffer will mitigate its visibility from the EC (however, it abuts and will be clearly visible from the parking area west of the building). Similarly, the southern walls on the west half of the site may be mitigated by extant screening and will be further mitigated once the 100-foot landscape buffer on the southern half of Block 8A is fully populated. There is no landscaping proposed between the stacked retaining walls; however, if the southwestern walls are visible, landscaping between them will be required. The proposed material is Diamond 15 Pro Stone Cut "Blue Ridge Range" block, which has a mottled, dark blue -and -salmon color, as per the brochure for the brand. No sample of the material has been submitted; this material was approved on the Final Site Plan for Blocks 4A and 4B, however, no material sample was reviewed at that time because staff believed the walls in those blocks would not be visible from the EC. 41 No grading, trenching, or tunneling should occur within the Only the 70-foot westernmost portion of the Provide sufficient tree drip line of any trees or other existing features designated 100-foot landscape buffer along Rt. 29 is protection fencing along the for preservation in the final Certificate of Appropriateness. marked for preservation (to be left eastern edge of the 70-foot Adequate tree protection fencing should be shown on, and undisturbed).

SUMMARY OF RECOMMENDATIONS Staff recommends the following as the primary points of discussion: 1. The potential visibility of the north, west and south elevations of the proposed building and what elevations will be required for future review. 2. The potential visibility of the retaining walls in the southwest corner of the site and whether additional landscaping will be required. Staff recommends that the ARB forward the following recommendations to the Agent for the Site Review Committee: • Regarding requirements to satisfy the design guidelines as per § 18-30.6.4c(2), (3) and (5) and recommended conditions of initial plan approval: 1. A Certificate of Appropriateness is required prior to final site plan approval. 16 • Regarding recommendations on the plan as it relates to the guidelines: None. Regarding conditions to be satisfied prior to issuance of a grading permit: 1. Provide sufficient tree protection fencing along the eastern edge of the 70-foot (undisturbed) landscape buffer on the site plans and prior to grading. Regarding the final site plan submittal: 1. Architecture and landscaping will be reviewed with a future submittal. A Certificate of Appropriateness is required prior to final site plan approval. 2.

ARB-2018-153: Longhorn Steakhouse- Initial Site Plan (TM/Parcel 0610000013200) Proposal: To construct a restaurant with associated site improvements. Location: 1531 Rio Road East, on the east side of Rt.29,just south of the Wells Fargo Bank. The ARB held a work session on the revised design of the Longhorn Steakhouse proposal,focusing on the pedestrian connection, the landscaping, and the architectural design.After discussion, it was the consensus of the ARB that: 1. The revised location of the pedestrian connection was an improvement, 2. The consistent spacing of street trees along the Rt. 29 frontage is required, and 3. Additional revisions to the architectural design are required to make the building design consistent with the previous ARB comments.Suggested revisions included, but were not limited to, the following:further simplification of form is required; brick and stucco would be acceptable materials; the design needs to move further out of the Southwest and into the Mid- Atlantic. b. Guidelines update The ARB held a work session on the Entrance Corridor Design Guidelines.They discussed historically significant buildings as precedents for appropriate color, material, and treatment of blank walls in the ECs, noting why some were appropriate examples, and why others were not. OTHER BUISNESS ITEM a. SDP-2019-02: UVA Tennis:Timing of CofA After considering the proposal, it was the consensus of the ARB that it was acceptable to delay approval of the architectural design of the tennis building until after site plan approval.
