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.

(Rev.1) Addressed.
D. 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.

2. Please provide VRRM for verification (by email is fln-
(Rev.1) Addressed.
3. Submit Forest/Open Space easement plat & deed. Plat & deed to be approved and recorded prior
to VSMP plan approval.
(Rev.1) Comment still valid.
4. Provide pictures of surrounding area to verify runoff from disturbed area will only sheet flow.
(Rev.1) Acknowledged. Reviewer may go out to verify area.
5. (Rev.1) Not all runoff from site will sheet flow. {9VAC25-870-66 D) The runoff from the
channels at the beginning of the driveway must be analyzed to meet water quantity
requirement under Part IIB. {9VAC25-870-66 A) Show your limit of analysis point.
E. 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. Cover sheet:
a. Include WPO# under title - WP0201900019.
b. Provide dates of topo survey and field verification.
(Rev.1) Addressed.
2. Existing Conditions sheets:
a. Please show the critical slopes correctly at the front of property.
(Rev.1) They don't quite match the County's GIS overlay. If you are claiming slopes are
less than 25% where the County's GIS steep slopes are you must demonstrate better
accuracy, based on newer survey data. Please provide an exhibit sheet comparison of the
site showing the county's steep slope overlay versus your surveyed topo. Labebhighlight
areas you claim are less than 25% slope. Please have licensed surveyor or engineer sign &
date exhibit sheet. Frank Pohl, the county engineer, will make the final determination.
b. Show tree line. (Rev.1) Addressed.
c. Show missing WPO stream buffer. (Rev.1) Addressed.
d. Show 100-yr floodplain. (Rev.1) Addressed.
e. Show drainage divide. (Rev.1) Not addressed. Show & label divide on sheet C4.
£ Show existing culvert & headwall and guardrails extending from it. (Rev.1) Not
addressed.
3. Please show proposed contours at 1' intervals where the grade is flatter.
(Rev.1) Please also label contour elevations.
4. Sheet 5: Locate Sediment Trap outside of the critical slope area & stream buffer. This
can be addressed by placing ST on opposite side of driveway.
(Rev.1) Not addressed. Engineering can not grant this waiver/exemption. 18-4.2, 14-
304
5. There appears to be proposed grades steeper than 2:1 adjacent to driveway.
Reduce grade to 2:1 or flatter.
(Rev.1) Addressed.
6. You're grading in critical slopes and I don't see why that's necessary outside of the
proposed driveway. Please justify why grading is needed in the critical slope areas.
Response: The grading of the hillside along Louisa Road is necessary for proper sight
distance.
(Rev.1) Existing critical slopes are not to be disturbed, unless a waiver or

(Plan is currently adequate)
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;
