Subject: SDP200900065 Old Trail Village Block 3 - Preliminary Site Plan
The preliminary site plan for Old Trail Village Block 3, revised and submitted on September 14, 2009, has
been reviewed. Current Development Engineering comments have been addressed.
Preliminary Site Plan Comments
1. Alleys will have aright-of-way or easement width of not less than 20 feet. [14 -410D]
REV #1: Comment has been addressed.
2. Alley surface must be paved to VDOT standards, with a width of at least 12 feet, with the gravel
base extended at least ' foot beyond the edges to either side. [DM]
REV #1: Comment has been addressed.
3. Alleys must intersect streets at two locations. Dead -end alleys with turnarounds may be permitted
by waiver from the county engineer. [DM]
REV #1: Comment has been addressed with the addition of turnarounds and connections.
These new features are proposed in the adjacent parcel, Phase C, which is under different
ownership than Phase B. Evidence of temporary construction and permanent access
easements will be required prior to the approval of a final site plan.
4. If driveways are designated parking spaces, dimensions must be 9x18x24' or 1Ox18x20'. [18-
4.12.16]
REV #1: Parking requirements are met via garages and on street spaces, driveways are not
required to meet parking space dimensions.
5. The angle of intersection of streets and alleys will be not less than eighty (80) degrees; however, a
perpendicular intersection, where practical, is preferred. [14 -410B]
REV #1: Comment has been addressed.
6. If it does not already exist, please provide a direct pedestrian link between the proposed
townhouses and the Village Center (Block 1). Concrete sidewalk should be constructed along Old
Trail Drive between Claremont Lane and Brookley Drive. [18- 32.7.2.8]
REV #1: Comment has been addressed. The sidewalk will be constructed adjacent to Old
Trail Drive between Claremont Lane and Brookley Drive with this project.
7. Capture site drainage before spilling into public right -of -way. Install inlets at entrances onto
Claremont Lane.
REV #1: Comment has been addressed.
8. Impervious area calculation on Sheet 4 does not appear to be correct. It appears that the areas of
streets and alleys were not included in the calculation.
REV #1: Comment has been addressed, calculation has been revised to include alleys,
streets are accounted for in previously approved Block 3 stormwater management plan
(WP0200800014).
9. Please submit information on Upper Ballard Pond and the storm sewer pipes to it showing that this
Block with this proposed impervious area was accounted for in the design.
REV #1: The approved Block 3 stormwater management plan (WP0200800014) predicts
this area (Phase B & C) to have a C value of 0.70 for 2.41 acres. Phase B is 1.195 acres at
approximately 0.80, therefore, the future development of Phase C (1.215 acres) may have a
C value not to exceed 0.60.
