Context Blocks 9, 10 and 11 are located in the northwest section of the Brookhill development (Figure 1). Block 9 is adjacent to Rt. 29. Block 10 is to the east of Block 9, and Block 11 is to the southeast. Brookhill Block 4B is to the south. Residential development (Forest Lakes and Montgomery Ridge) is to the north and east. Visibility The residential units of Block 9 will be the most visible from the EC street. Blocks 10 and 11 are not expected to have much visual impact on the EC due to their increasing distance from the street and the topography that falls away to the east. The visibility of Block 9 will be reduced by the landscape buffer that is required along Rt. 29. The lower portions of many of the Block 9 units will be below the grade of the EC street and shielded by topography as viewed from the street. The roofs and upper portions of the units will be visible through the trees of the wooded buffer and, in the future, through trees added to the buffer. ARB Meeting Date July 6, 2020 Staff Contact Margaret Maliszewski PROJECT HISTORY The ARB reviewed and recommended approval of an Initial Site Plan for these blocks on March 2, 2020. At that time, the ARB determined that Blocks 10 and 11 would not require further ARB review due to limited visibility. Consequently, this staff report is limited to review of Block 9. No changes have been made to the architectural design since the March review. Primary changes to the site plan since the March review are related to landscaping.

The scale of the buildings is expected to appear appropriate from the EC street. The lack of detail on the EC -facing elevations would not typically be considered appropriate for the EC. However, the required buffer along Rt. 29 is expected to reduce some of the visual impact of the development on the EC. As such, the buffer will also serve to promote orderlyand attractive development. 5 It is also an important objective of the Guidelines to establish a pattern of compatible See landscape The landscape buffer that is required See landscape architectural characteristics throughout the Entrance Corridor in order to achieve unity recommendations. along Rt. 29 will establish a level of unity recommendations. and coherence.

Though the rear elevations are largely devoid of architectural detail and character, the windows, doors and wall heights appear standard and reflective of human scale. The roofs may have a substantial visual impact as viewed from the front and side, but this is not expected to have a significant impact on the EC street due to the orientation of the blocks and the landscape buffer. 13 Any appearance of "blankness" resulting from building design should be relieved See #9.

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.

An organized pattern of roads, service lanes, bike paths, and pedestrian walks should guide the 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 appropriateness of the architectural designs of the EC -facing rear and side townhouse elevations 2. Landscaping proposed for the buffer Staff recommends approval of the proposal with the following conditions: 1. Add shrubs to the mix of plants in the buffer. 2. Coordinate the plant schedule with the landscape plan. 3. Clarify on the landscape plan the extent of planting included in Block 9. 4. Limit the number of proposed plants for any one species to 25% of the total proposed for that plant type (tree, shrub). 5. Recommendation: replace the Russian sage with a locally native plant. 6.
