VSMP Permit Plan Review
Project title:
Foothill Crossing Phase VI West
Project file number:
WPO -2016-00003
Plan preparer:
Collins Engineering
Owner or rep.:
Foothill Crossing, Inc.
Plan received date:

Date of comments:

Reviewer:

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 denied. The
rationale is given in the comments below. The application may be resubmitted for approval if all
of the items below are satisfactorily addressed. The VSMP application content requirements can
be found in County Code section 17-401.
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 ESOP, (3) a SWMP, and (4) any TMDL measures necessary.
1. An operator must be named, and must sign the certification statement and applications. If there is
no designated contractor or project manager, it should be the owner of the property.
Stormwater Management Plan (SWMP)
1. Basins should have side slopes no steeper than 3:1 for maintenance and safety issues. [VaSWM
Handbook]
2. Show how the basin will be accessed for maintenance. DCR BMP Spec. 15 provides guidelines
for maintenance access.
3. Readily accessible basins in populated areas should include all possible safety precautions. Rails or
fencing along the retaining wall should be considered. [VaSWM Handbook]
4. Provide plans for the retaining wall and verification that there is no issue with the wall foundation
being submerged during storm events. Shorter (<4') will not require this verification.
5. Provide a planting plan for the BMP. [VaSWM Handbook]
6. Having the spillway directly over the outlet pipe may cause issues in the future. Relocate the pipe
if possible.
7. The VRRM worksheet shows 10,164 cf for the treatment volume. Where did the 7,696 cf number
come from on sheet 5?
Erosion and Sediment Control Plan (ESOP)
1. The sediment basin has a diversion entering near the riser that appears to carry more than 30% of
the inflow. Use baffles to increase the flow path. [VaESCH 3.14]

The VSMP permit application and all plans may be resubmitted for approval when all comments have
been satisfactorily addressed. For re -submittals please provide 2 copies of the complete permit package
with a completed application form.
Engineering plan review staff are available from 2-4 PM on Thursdays, should you require a meeting to
discuss this review.
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.
County forms can be found on the county website forms center under engineering;
