Context and visibility The proposed work is located at the Keswick Sewage Treatment Plant, just north of an existing wastewater structure that is similar in appearance to the proposed tank. Other treatment plant structures are in the area. The I64 Entrance Corridor runs along the southwest side of the property. The proposed tank is approximately 90' from the property line on that side. A wooded buffer is present there, but it is mostly in the right-of-way. The wooded area limits visibility of the existing treatment plant structures, particularly in the months when leaves are on the trees. The view is more open in the winter months. The proposed structures are expected to have a level of visibility similar to that of the existing structures. See Figures 1 and 2.

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 placement of structures on the site should respect existing views and vistas on and around the site.

Visibility of the proposed development 2. Suitability of the proposed landscape screening Staff recommends approval with the following conditions: 1. Provide in the site plan a cut sheet for the wall pack light fixture that shows it is a full cutoff fixture. Include a diagram and/or note on the plan indicating that the level of illumination at the ground emitted by the fixture does not exceed 20 fc and that the light color is in the range of 2000- 3000K. 2. Confirm that no lighting other than the wall -pack on the electrical building is proposed. 3. Add the standard lighting note to the plan: 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." 4. Add the standard plant health note to the 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." 5. Show that grading will not impact trees to remain. 6. Include tree protection on the plan.
