County Code section 17-410 and Virginia Code §62.1-44.15:34 requires the VSMP authority to
act on any VSMP permit by issuing a project approval or denial. This project is approved
contingent on approval/ record of the deed of dedication and easement Plat for SWM forest
and Open Space. The VSMP application content requirements can be found in County Code
section 17-401.
A. Stormwater Pollution Prevention Plan (SWPPP)
The SWPPP content requirements can be found in County Code section 17-405. A SWPPP must
contain (1) a PPP, (2) an ESCP, (3) a SWMP, and (4) any TMDL measures necessary.
[C 1.1 ] Critical slope areas must be shown on plans
Rev 2 — Partially addressed. It appears the layer may be switched of or was not printed
correctly. Please correct on approval copies.
Rev 3 — Addressed
[C 1.2] Reposition callout arrows in roadway profile to better identify represented features.
Rev 2 — Addressed.
B. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17-404.
No Objection
C. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a
SWMP. This plan is approved contingent on approval/ record of the deed of dedication and
easement Plat for SWM forest and Open Space.
Engineering Review Comments
Page 2 of 3
The wetted area of the existing pond on site cannot be used for SWM forest and open space credit.
Please adjust VRRM numbers accordingly.
Rev 2 — Addressed.
Forest and Open space used for water quality credit must be labeled as "SWM Forest and Open
Space Easement". Forest and Open Space must be placed easement with associated deed of
dedication and SWM maintenance agreement prior to final VSMP approval.
Rev 2 — Acknowledged. Label updated, submittal of easement Plat and Deed of dedication
needed.
[C 1.4] Provide reasoning for not including level spreaders for discharges for culverts 5 and 6.
Rev 2 — Adequately addressed.
Additional Rev 2 Comments:
1. Rational method worksheet for Culvert 5 does not correctly display C -factor, 2yr, and 10yr
flowrates. In addition, the worksheet headers reference the wrong project. Worksheets
should have seal signed by professional engineer. Please correct and provide on final
submittal.
Rev 3 - Addressed
D. Erosion and Sediment Control Plan (ESCP)
Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESCP.
This plan is approved contingent on approval/ record of the deed of dedication and easement
Plat for SWM forest and Open Space.
[C 1.1 ] Add tree protection to the list of E&SC measures.
Rev 2 — Addressed.
[C 1.1 ] Show locations of rip rap outfall channels for sediment traps.
Rev 2 — Addressed.
[C1.1] Structures diverting non -sediment laden runoff should be identified as clear water
diversions.
Rev 2 — Addressed.
[C1.1] Easternmost diversion dike must discharge into a sediment trapping device or proper
stabilized outlet. The 200 foot distance between end of diversion and proposed roadside ditch will
potentially cause channel ization/erosion issues.
Rev 2 — Addressed.
[C1.1] Diversion dike discharging into sediment trap 2 is conveying water perpendicular to the
slope. Should be replaced by temporary slope drain or similar measure. The angled change in
direction in diversion shown at bottom of slope will cause spillover if installed as shown. Please
address.
Rev 2 — Addressed.
6. [C1.1] Silt fence should not be installed crossing contour lines. In several locations west of the
proposed drive the silt fence is shown to be installed perpendicular to the slope. These areas
should be replaced with short sections of SF parallel so the slope.
Rev 2 — Addressed.
7. [C 1.3] Provide outlet protection sizing for each outfall, or identify that all will follow sizes
provided in detail.
Rev 2 — Addressed.

Additional Rev 2 Comments:
1. Sediment trap 1 identifies the top elevation of the weir to be higher than the max
embankment height. Please correct.
Rev 3 - Addressed
Approval is contingent on record of the deed of dedication and easement Plat for SWM forest and
Open Space Easements.
Process;
After approval, plans will need to be bonded. The bonding process is begun by submitting a bond estimate
request form and fee to the Department of Community Development. One of the plan reviewers will
prepare estimates and check parcel and easement information based on the approved plans. The County's
Management Analyst will prepare bond agreement forms, which will need to be completed by the owner
and submitted along with cash, certificates or sureties for the amounts specified. The agreements will need
to be approved and signed by the County Attorney and County Engineer. This may take 2-4 weeks to
obtain all the correct signatures and forms.
Stormwater Management Facilities Maintenance agreements will also need to be completed and recorded.
The County's Management Analyst or other staff will prepare the forms and check for ownership and
signature information. The completed forms will need to be submitted along with court recording fees.
After bonding and agreements are complete, county staff will need to enter project information in a DEQ
database for state application processing. DEQ will review the application information based on local
VSMP authority approval. At this time, the DEQ portion of the application fees will need to be paid
directly to the state. For fastest processing, this is done electronically with the emails provided on the
application. DEQ should notify applicants with instructions on how to pay fees. When DEQ approves the
application, they will issue a permit coverage letter. This should be copied to the county.
After DEQ coverage is issued, via the coverage letter, the County can hold a pre -construction conference.
Applicants will need to complete the request for a pre -construction conference form, and pay the remainder
of the application fee. The form identifies the contractor and responsible land disturber, and the fee
remaining to be paid. This will be checked by county staff, and upon approval, a pre -construction
conference will be scheduled with the County inspector. At the pre -construction conference, should
everything proceed satisfactorily, a joint VSMP and grading permit will be issued by the County so that
work may begin.
