Below is a summary of how the conditions of the initial site plan have been addressed: Planning Comments: 1. This comment is acknowledged. No changes are needed to the plan. 2. The plan has been approved as an initial site plan, and is being submitted now as a final site plan. The border has been updated accordingly. 3. This parcel is not included in the site plan and the acreage is not identified on the plans or in the density calculations. The project area currently reflects just the (1) parcel 4. TMP78-20M5 has been identified on the Overall layout sheet and plans as a parcel for future dedication to the County for public use, as requested. 5. All the existing easements as shown on the plan set and the proposed public and private easements have been shown and labeled on the plan. 6. The deed book and page numbers have been added to the plan sheet and existing conditions. 7. Sheets 5A and 5B have been created to show the portions of the site to the east and the west. Matchlines have been created from Sheets 4, 6, and 8 to match to this area, and show the necessary information. 8. This comment is acknowledged. No changes are needed to the plan. 9. This comment is acknowledged. No changes are needed to the plan. A note has been added to the plans indicating that the connection shall be constructed to standards established in the Albemarle County Design standards manual, ADA requirements, and VDOT standards. 10. The connection across PJP has been shown on the plans, as indicated in the comment letter. A note has been added stating that this connection must be designed and constructed to standards established in the Albemarle County design Standards manual, and all ADA ramps shall be designed and constructed to the standards of VDOT.

The overall recreational amenities summary on sheet 1 has been updated, as requested. The overall requirements have been shown as requested. The amenities and amenity area has been updated to reflect the amenities to be added to the project. These amenities do not include the parcel of land that is also being dedicated to Albemarle County, outside of the amenity package for the development. 17. As discussed at the SRC meeting, the adjacent 4.5 acre parcel is being reserved for dedication to Albemarle County. This property can be used in conjunction with other land to create the trailway connection to the Rivanna River. This parcel will help provide the connection and give the County a starting point for the design of the trailway to the River corridor. This dedication meets the requirements of this comment. 18. This comment is acknowledged. Engineering Comments: 1. The title of the site plan has been updated to reflect the Final Site plan submission. The initial site plan has been approved. 2.

The Layout sheets and notes on the cover sheet have been updated to reference all travelways as private travelways in the apartment complex. These travelways shall have road names for GIS mapping/Mail service, and Fire/Rescue. b. As noted, all drainage easements will be private within the development, since none of them will be receiving run-off from public right of ways. The drainage easements have been shown and labeled on the plans. The utility easements will be public easements. c. The comment has been withdrawn. d. For clarity, this note has been updated to state that the streets within this development are private travelways. (Note, see further explanation under response 10). 4. As discussed in the meeting on March 5th, Roudabush and Gale have performed additional onsite survey and topography on the site, and have confirmed that the topography is accurate. This additional topo information has been added to the plan sheet and the note on the cover sheet has been updated to reflect this additional information. 5.
