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. No additional fee is required for resubmittal. 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 ESOP, (3) a SWMP, and (4) any TMDL measures necessary.
Please submit a Stormwater Pollution Prevention Plan per 17 -302 and 17 -405
Response: Comment appears adequately addressed at this time.
A. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17 -404.
Please submit a Pollution Prevention Plan per 17 -302 and 17 -404.
Response: Comment appears adequately addressed at this time.
B. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25- 870 -108 requires the VSMP authority to approve or disapprove a
SWMP. This plan is disapproved, and the reasons are provided in the comments below. The
stormwater management plan content requirements can be found in County Code section 17 -403.
1. No forest exists on this property, only scrub trees on 1:1 slope above site. Please revise the VRRM
spread sheet for review.
Response: VRRM Spread sheet does not appear to match site. VRRM appears to add the offsite
drainage area to the calculations. VRRM calculations must be for the site area only. Capacity of
basins requires the total drainage area to prevent the basin from blow -out, but the VRRM does not.
Please revise the VRRM Spread sheet to reflect the State requirements for approval. Complete review
of VRRM will be conducted once areas match site.
2. SWM basin details do not appear to match plan view. Details show 50' from top (lip) of basin to
back of curb and the plan view appears to show little or no distance to back of curb. Guard rail

may be required for protection.
C. 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 disapproved, and the reasons are provided in the comments below. The erosion control
plan content requirements can be found in County Code section 17 -402.
1. Diversion across front of site does not appear to be required. Please explain purpose if you would
like it to remain.
Response: If diversion is to be proposed across the entrance then a pipe will be required to convey
stormwater from sediment trap to inlet by going under the construction entrance. Please show a 15"
pipe under the construction entrance. This office continues to recommend utilizing the exiting inlet
shown to be removed as the conveyance from the sediment trap instead of a diversion and pipe across
the temporary entrance.
2. Silt fence will be shown with the ends turned upslope to prevent the water from running around
the end before filtering through the fabric.
Response: Comment adequately addressed at this time.
3. Paved temporary construction entrance appears to drain into the road. Please show the temporary
paved construction entrance wash area to drain to basin. May need a site specific design for this
project.
Response: Temporary paved construction entrance must be directly connected to the existing
pavement to prevent mud tracking onto road surface. One foot gap is not approvable. Sediment
catchment is acceptable, but detail is illegible.
4. ST -2 could use the existing inlet (to be removed) for its outlet structure so water does not enter
travel way from sediment trap.
Response: Existing pipe profiles and inverts are not included with submittal. Consultant response
could not be verified at this time.

Appears
sediment trap could be raised less than a foot to utilize the existing invert of 404.94 or 402.38
to save the contractor from crossing a piped diversion to access the site.
The 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 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;
