Reviewer:

The Cascadia plans have received Engineering Review. The Following items will need to be
adequately addressed prior to final approval:
A. Street plan (SUB2013000091)
(A separate road and drainage plan is required if the property is to be bonded for subdivision.)
1. VDOT approval is required. We are awaiting approval from VDOT.
B. Site plan (SDP2013000025)
(A site plan is a record of zoning compliance on the property. It should not include VSMP plans.)
All comments appear to be addressed. The stormwater management plan and road plans will need to
be approved before I can recommend approval to planning.
C. Plat (SUB2014000106)
(A plat is a record of property division or reservation. Code Chapter 14)
1. All streets and infrastructure must be approved and bonded prior to plat approval.
2. All easements must match approved stormwater and street plans. Please include all stormwater facility
easements, access, and easements for mitigation areas, per the VSMP plans.
D. VSMP: SWPPP and Pollution Prevention Plan (WP02013000032)
(The Virginia stormwater management program, stormwater pollution prevention plan application and
documents)
1. Please provide the DEQ coverage letter.
E. VSMP: SWPPP: Stormwater Management Plan (WP020130000032)
1. Show vehicle access to all facilities with easements. Include easement to pond 1 from Delphi or an
internal road. Include access to the biofilters and water quality swale.
Engineering Review Comments
Page 2 of 2
Rev.A: Acces to BF -1 and the Water Quality Swale was not found. It is not clear how vehicles get to
the facility itself, or how the proposed access road gets beyond BF -2 and outfall. All accesses need to
be a minimum 10' wide. Please update the other sheets of the plan to match. The erosion control
sheets do not match.
Regarding the water quality Swale:
12. Provide accurate details for the water quality swale. Show soil mixture, underdrain, minimum bottom
width, maximum slope, side slopes and top width.
Rev.A: The soil mixture and underdrain were not shown. The grassed swale option does not appear to
obtain the needed removal rate.
13. Provide computations to show hydraulic adequacy per standard spec. 3.13.
Rev.A: The calculations appear to show depths greater than the weirs.
F. VSMP: SWPPP: Erosion and Sediment Control Plan (WPO2013000032)
1. The erosion and sediment control plan is approved. Comments have been addressed.
G. Mitigation Plan (WPO2013000032)
(A mitigation plan is a plan of buffer disturbances, and replanting or restorative measures)
1. The mitigation plan is approved. Buffers and easements for mitigation areas will need to be shown on
final plats.
H. Bond Estimate Request for VSMP plans (WPO2013000032)
1. The bond estimate request will be processed when all VSMP plans are approved.
