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/approved. The rationale is given in the comments below. 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.
Please use Albemarle County SWPPP template:
https://www.a I bemarle.orci/home/showpu bl isheddocu ment/166/637202310327530000
2. Ensure registration statement and section 9, signed certification are signed.
B. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17-404.
Please provide a PPP. See 17-404 for required contents:

17%20Water%20Protection.pdf
C. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a
SWMP. This plan is denied, and the reasons are provided in the comments below. The
stormwater management plan content requirements can be found in County Code section 17-
403.
A stormwater management maintenance agreement must be recorded before this plan
can be approved. Please contact Ana Kilmer [akilmer@albemarle.org 434-296-5832
ext.32461 to complete this process.

2. Since forest & open space is being used in the VRRM, this area must be shown on a plat
labeled as SWM forest & open space and recorded with a deed before this plan can be
approved. There must also be an easement labeled SWM Facility easement around the
proposed pond and its outfall and access area. The easement plat application can be
found here: https://www.albemarle.orci/home/showdocument?id=1052
3. Please add the following note to this plan and the plat mentioned in the above
comment: "The SWM Forest and Open Space Easement is subject to the guidance set
forth by DEQ in the Virginia Stormwater Management Program. The areas will remain
undisturbed in a natural, vegetated state, except for activities as approved by the local
program authority, such as forest management, control of invasive species, replanting
and revegetating, passive recreation (e.g., trails), and limited bush hogging to maintain
desired vegetative community (but no more than four times a year)."
4. Please clarify where the 17.5 acres of forest & open space is located. The legend appear
incorrect on sheet 2.
5. Please add a title to sheet 1 and include WPO202100033 in the title.
6. Professional seal should be signed and dated.
7. Please provide date the topographic information was obtained/survey was completed.
8. Please show the WPO buffer and any critical slopes from county GIS on all applicable
sheets.
9. It would be helpful to have a grading and layout sheet separate from the E&S sheet.
10. Please double check all grading and contour labels. The northern end of the site appears
to have 1 ft contours tying in to 2 ft contours. Also, the proposed contours do not match
the labels on the northwest side of the site.
11. Is the disturbed area 7.65 acres or 7.71 acres? There is a discrepancy in the plans.
12. Please label contour elevations on all applicable sheets, especially the drainage divides.
13. Please list the required maintenance for the proposed SWM pond on the plans.
14. Please provide the following as -built check list on the plans:
https://www.albemarle.orci/home/showpublisheddocument/3381 /637327510536700000
15. On page 5 of your calculations packet, please clarify that you are meeting flood
protection by 9VAC25-870-66-C2B (it appears you were missing the Q.
16. Please provide a detail for the emergency spillway for the permanent dry pond.
17. Per 9VAC25-870-66-B, concentrated stormwater flow shall be released into a stormwater
conveyance system. The currently proposed outfall does not appear to go into a
conveyance system or channel.
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. Please provide the paved CE with wash rack detail from the Albemarle County Design
Standards Manual (page 8): https://www.albemarle.org/Home/ShowDocument?id=270
2. Please show dust control as an E&S measure.

3. Please show a stockpile, staging and parking area.
4. Please provide adequate perimeter control, including silt fence around the southern and
eastern ends of the project.
5. Ensure Albemarle County Standard Notes are on the plan:
https://www.a I bem arle.orci/home/showpu bl i sheddocu ment/1262/637321325255330000
6. Provide details for the trash rack and anti -seep collars.
7. Please clearly show the drainage area for the sediment basin as well as the required dry
and wet volume storages.
8. Please add a note to the plans that County Inspector may require additional measures as
needed on site.
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, erosion and sediment control and stormwater management improvements must
be bonded. The bonding process begins when the plan is approved, and the applicant submits a
bond estimate request form and fee to the Department of Community Development. A plan
reviewer 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 to the
County, who will record the agreement.
After bonding and agreements are complete, county staff enters project information in a DEQ
database for state application processing, if a DEQ permit is required. DEQ reviews 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, which must be posted at the construction site.
After DEQ coverage is issued, via the coverage letter, the County can hold a pre -construction
conference. Applicants must 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, ajoint 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;
