The Final Site Plan for SOCA Field House, received on 20 April 2010 has been reviewed. The plan cannot
be approved as submitted and will require the following corrections before approval can be granted:
A. General Review Comments (SDP201100024)
1. Please provide a benchmark location, elevation, and datum for topography. An existing utility or
other known position n will suffice.
2. All entrances must have VDOT designations (PE -1, CG -9a, etc.)
3. VDOT approval must be obtained prior to site plan approval.
4. Curbing on all parking areas and travelways must have VDOT designations (CG -2, CG -6).
5. All edges of pavement with no curbing must be specified on the plans.
6. Please provide arrows on all existing and proposed storm sewers.
7. Direction of flow change (or deflection angle) in each drainage structure must be 90 degrees or
greater.
8. Please provide the specification for the dumpster pad stone base.
9. Please label and show existing and proposed ground on the drainage profile.
10. Please show all utility crossings on the drainage profile.
11. Please provide a proposed pipe and inlet drainage area map showing acreage, hydrologic
coefficients, and time of concentration.
12. Please provide calculations and inlet type for Inlet #1
13. It appears that the application number used on the E &S plan indicating an existing sediment trap is
incorrect. The correct application number is WP0200600048 and the existing sediment trap is no
longer active. Please revise.
14. No inlets are shown on the proposed cistern. Please show how the cistern will receive the runoff
(roof drain, gutters, etc.). In addition, please provide calculations from the proposed cistern to
Belvedere Village Green.
B. Erosion and Sediment Control Comments (WP0201100026)
15. The existing biofilter cannot be used as a sediment control facility. Engineering recommends two
options: The first option is to provide a sediment trap southeast of the existing biofilter so as to
capture the sediment before it enters the biofilter. The second option would be to convert the
biofilter into a sediment trap, and then convert it back into a biofilter once the site has been
stabilized.
16. Additional E &S comments may be forthcoming once a perimeter control has been shown.
