Sunset Overlook (SDP201500006)
The initial site plan for Sunset Overlook has been reviewed. The following concerns should be addressed;
1. Remove disturbances from preserved slopes. Aerial topography will not warrant removal of
preserved slope designations. A field survey provided by a licensed Professional Surveyor would
be required. In addition, while it is possible that a field survey may prove that some slopes
designated as preserved are less than 25 %, it will likely warrant additional areas to be designated
as preserved, as the site must be reevaluated as a whole. The steep slopes overlay district tries to
preserve contiguous areas, so results of any new evaluation will need to avoid breaking slope areas
into fragments. [39.7.4(b)(h)]
2. Stormwater management does not appear adequately addressed with this plan. A large portion, if
not majority, of the site appears to be untreated. SWM facilities would be better suited at the low
side of the site (B 1 and 132). The proposed drainage to these facilities would be very difficult to
implement, if possible, and appear to only treat the road, at best. Much of the drainage intended,
presumably, to be captured by SWM Al would bypass this facility. It is unclear to us how your
SWM plan would be effectively implemented, given the locations of your facilities. A VRRM
spreadsheet printout should be provided showing how you plan to comply with Type IIB criteria.
3. Proposed grading, generally, does not tie in with existing topography on this plan. All proposed
grading, including for SWM facilities, must be provided and tie in with existing topography.
Provide more labels for proposed topography.
4. The drop inlets between lots 14 and 15 appears to route stormwater from "Street A" and much of
the western portion of the site directly offsite, untreated. This must be changed.
5. A County approved turnaround must be provided at the end of all proposed streets (Street C), see
Albemarle County Design Standards Manual. Turnarounds should be 6% grade or flatter.
6. Arrangements must be made and documented with the owner of parcel 76 -52N concerning grading
on that off -site property and removal of the driveway and along Street A. Lots cannot overlap this
parcel (Lot 16). Additionally, it must be shown that excess runoff will not pass through this or
other parcels as a result of this development.
7. SWM facilities cannot be on residential lots.
8. Retaining walls should not result in the disturbance of preserved slopes. Please adjust retaining
wall heights and locations.
9. Retaining walls must be, at minimum, a distance equal to the height of the wall away from
adjacent properties, please adjust. Alternatively, easements for work on adjacent property should
be provided.
10. More detail is needed to show how the retaining wall extends into SWM B1.
11. On- street parking must be striped.
