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.
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.
The SWPPP has been submitted for review and appears to require the owners signature on the section
#9 "Certification". Other than the required owner's signature the SWPPP appears to be adequate at
this time.
B. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17-404.
1. Appears to be adequately addressed at this time.
C. 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. Please make Spread sheets congruent with plans:
a. The VRRM spread sheet states 2.59 acres impervious.
b. TR -55 worksheet states 3.15 acres impervious.
c. The cover sheet of the plan states 5.78 acres impervious.
2. The access road to the facility does not appear to allow for the maintenance and repair of the
forebay without crossing over the bio -filters. Cleaning of the forebay may be more often than the
maintenance of the outlet structure. VSMH 3.01, page 301-14
3. The junction from the SWM structure to the existing stream is shown almost perpendicular. The
connection should be more oblique. Otherwise the opposite side of the stream bank may require

armament to prevent scouring and erosion.
4. Emergency spillway does not appear to meet the VSMH 3.03 requirements. Please move the
spillway to existing or cut ground, or redesign the basin to meet Va. State Standards.
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 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. The site is covered in mature trees. Trees will need to be removed before any grading can begin.
The plan appears to require a substantial amount of grading to install the initial perimeter controls
to protect the site. The sequence of construction does not include the important step of removing
the trees. It appears the site will be without perimeter protection for an extended amount of time.
Please revise the sequence of construction to protect the site with the least amount of tree removal
and an expedited installation of the perimeter erosion and sediment control measures. The
contractor does not have permission to clear cut the site prior to installing the perimeter controls.
2. The silt fence across the swale may need to be wire -supported (per VESCH 3.05, conditions where
practice applies #2). A temporary sediment trap would be better protection in this area.
3. Diversions across swales have not been successful on other projects. This office suggests a
sediment trap until the site drainage can be directed into the proposed basin.
4. Proposed lots with diversions will not receive building permits until the VSMP inspector has
determined the measures are no longer required for the overall protection of the site. Please note
this on the plans.
5. The proposed grass lined spillway does not appear to meet the minimum requirements of an
emergency spillway in VESCH 3.14 and shall be located so that it will not be constructed over fill
material. Please move the spillway or redesign the basin so the principle spillway is also the
emergency spillway.
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;
