A. Site Development Plan (SDP201300005)
1. It appears there is one critical slope located south of site that will be be slightly disturbed during
the construction of the additional gravel area. It also appears that the runoff for the entire site will
be routed into a stormsewer with the outflow concentrated near the critical slope area. The
applicant requesting the waiver shall file a written request explaining how the waiver, if granted,
would address the rapid and/or large -scale movement of soil and rock, excessive stormwater run-
off, siltation of natural and man -made bodies of water, loss of aesthetic resources, and, in the event
of septic system failure, a greater travel distance of septic effluent (collectively referred to as the
"public health, safety, and welfare factors ") that might otherwise result from the disturbance of
critical slopes. [Section 4.2.5]
2. Please show the drainage easements within the property boundary.
3. The property drains into a lake managed by the Forest Lakes Community. Per Section 17.314 and
section 17.315, water quality and quantity will need to be addressed. A WPO application can be
filled out for the stormwater management and erosion and sediment control review. The load
reduction calculation spreadsheet can be found on our website,
www .albemarle.org/deptforms.asp ?department =cdd. The file name is Plan Review BMP Removal
Rate Computations.
4. Please show the the VDOT Flared End Section ES -1 for the outlet pipe.
5. The area between the proposed grate inlets will start ponding. Please revise to prevent ponding.
6. Please provide the detail of the F wide wall located south of site.
7. On sheets 5 and 9 for post development, please do not show the grate inlet and pipe to be
removed.
8. Please revise E2 to be a 24" RCP outlet pipe.
9. The site will eventually drain into (2) — 12" DIP before entering the pond. Please replace pipes
with a 24" RCP. This will require permission from the Forest Lakes Community Association, Inc.
Please provide.
Sincerely,
Michelle Roberge
County Engineer
