Please find attached to this letter 10 full size sets (24"x36") of the revised site plans. The general layout and grading concept for the site has been revised since the initial plan submission, in an effort to limit the need of retaining walls and balance the site. Please see sheets C4.0-C4.2 for the revised layout plan and sheets C6.0-C6.2 for the revised grading plan. Additionally, the proposed SWM strategy for the site has been revised to replace the formerly proposed underground detention facilities with a large pond in the northeast corner of the site to meet the site's detention requirements. Full design and detail of this pond and all other SWM calculationstsupporting information will be provided prior to final site plan approval. Below is the latest edition of the County's review comments, followed by the response in bold italics: Albemarle County Planning Services Cameron Langille [General Comment] Prior to initial site plan approval, the zoning violation pertaining to the recreation areas required by the County forthe mobile home park north of this site must be rectified. The site plan for the mobile home park showed the required recreation amenities being installed on TMP 32-53 and 32-54. However, these features were never installed. New development applications for developments on TMPs 32-53, 32-54, and 32- 55 cannot be approved by the County until this violation is resolved. A letter of revision is currently under review with the County to address this issue. Comments have been sent to the applicant, but the County is awaiting a final response. Applicant acknowledges that this zoning violation is currently being resolved by the landowner and County. 2. [30.2.61 The project lies within the Airport impact Area (AIA) Overlay Zoning District.

There is no 20' setback in the R-15 zoning district (this includes front, side and rear). The maximum front setback is "25 feet from the right-of-way or the exterior edge of the sidewalk if the sidewalk is outside of the right-of-way." The front setback should be applied on the eastern development boundary, which means Building 7 currently does not meet the maximum front setback. Building 7 will need to be moved closer to property lines to comply with the setback. a. At least one building must comply with the minimum and maximum front setback. Staff suggests reversing the location of building 7 and the row of parking east of Building 7. This will move the building closer to the property line to comply with the maximum 25' front setback.

Albemarle County Engineering Services John Anderson Engineering; defers to Planning; for ISP approval. 1. Boundaries ofTMP H32-53 do not match currant real estate records. Sheet C2.0 indicates parcel boundary to be abandoned by separate instrument:, but this poses several issues: a. If ISP were approved and boundary is not abandoned with new boundaries created to match ISP, there are design implications, beginning with site plan approval for an unrecorded parcel. b. Similar to a., Sheet 0.0 bonus density relies on boundary adjustment that creates a parcel of 17.40 Ac., which does notexist at present. l?ngincering; rcconitnen is against bonus density that reflects 17.40 Ac. unless recorded boundaries match overall acreage shown on C0.0 and(;2.0.
