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 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 ESOP, (3) a SWMP, and (4) any TMDL measures necessary.
1. Please provide a SWPPP using the standard template from the County website addressing all
items in County Code section 17-405. Please include your registration statement. While a
drainage narrative was provided with this submission, a SWPPP was not found.
(Rev. 1) Comment not addressed.
(Rev. 2) Addressed.
2 -Pro ide a eopy of the DEQ eee letter -when bt : Provide PPP site exhibit sheet; Fill out
(Rev. 2)
Response: Kimley-Horn submitted SWPPP to the County on February 24, 2017.
(Rev.3) Addressed; Provide PPP exhibit sheet.
B. Pollution Prevention Plan (PPP)

A PPP was not provided. Please provide a PPP addressing all items in section 17-404 of the
County Code.
(Rev. 1) Comment not addressed.
(Rev. 2) Comment not addressed.
Response: Kimley-Horn submitted the PPP information within the SWPPP to the County on
February 24, 2017. A plan showing the pollution activities and prevention practices will be
submitted once a Contractor is selected.
(Rev.3) Addressed.
C. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a
SWMP. This plan is approved, 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. The purchase of credits will need to be approved by the County Attorney's Office. Please contact
Ana Kilmer akilmer@albemarle.org for required information and documentation for credit
purchases prior to finalizing the purchase.
(Rev. 1) Comment not addressed.
(Rev. 2) Addressed.
2. Fill in the nutrient purchase information in the CBPC boxes (Title & 1H(1) pages).
(Rev. 2)
Response: Kimley-Horn added the nutrient purchase information on the Sheet 1 & 1H(1).
(Rev.3) Addressed.
3. Remove triangle symbols in legend area that aren't called out on the plan sheets.
(Rev. 2)
Response: Kimley-Horn removed any triangle symbols that were called out on the plan sheets.
(Rev.3) Addressed.
Revision 1 Comments
4. The installation of the pipe leading to "Outfall 1" and the proposed underground detention system
are not included in your limits of disturbance, please correct.
(Rev. 2) Addressed.
5. Provide profiles+ for proposed pipe and associated structures.
(Rev. 2) Addressed.
6. Provide more information concerning the proposed underground detention system. What is its
capacity? How exactly does it factor in to reducing the discharge at "Outfall 1 "? This may be
buried in your calculation booklet but should be detailed in the plans.
Response: Please see sheet 1H(1) and sheet 7(2) the detention system details.
(Rev. 2) Addressed.
Recommend to show design storm elevations for the underground detention [Sheet 7(2)].
(Rev. 3) Addressed.
7. Please include the pre- and post -development drainage area plans (inserted in to your calculation
booklet) in the actual VSMP plan set. Some of the drainage areas appear unrealistic relative to the
provided contours, please explain.
(Rev. 2) Partially addressed --Show drainage area/divides to outfalls for verification.
Page 3 of 5
Response: Kimley-Horn has updated the drainage areas to match the provided contours.
However, the areas for Area 3 estimated based on the future design of the Out -of -Bounds
property which has recently been developed. The Out -of -Bounds contours (which should now be
existing due to completion of the job) are not shown in the GIS of the Pre and Post Development
Areas Maps.
(Rev.3) Addressed.
8. The project description in your calculation booklet references a total project area of 0.51 acres
and a total area to be disturbed of 0.94 acres. This is confusing, please clarify. You also reference
a required 10% pollutant reduction; however, "Situation 3" does not require a straight 10%
reduction, as your calculation show. Please clarify this.
(Rev. 2) Partially addressed --Please indicate `total project area' and `total area to be disturbed' on
plan for clarification. Are the areas outside of `total project area' in easements?
Response: This project is grandfathered under part IIC of the technical criteria. In the "old
regulations" the project area for linear projects is measured only in the proposed right-of-way.
This project will be constructing slopes beyond the right-of-way line that will be disturbed but are
not a part of the official measured project area. In the "old regulations" these grassed slopes do
not contribute to the overall pollutant load.
The quality reduction calculations have been clarified. Area 1 falls under "Situation 1" and only
is required to reduce the pollutant load to the statewide average land cover condition. Area 2 falls
under Situation 3 and is required to reduce the pollutant load by 10%. The sum of these removal
requirements is the project -wide removal requirement.
(Rev.3) Addressed.
9. 20' (Min) drainage easements. Refer to the storm easement width calculation, and adjust
proposed easements accordingly (Design Manual, Sect. 6).
(Rev. 2)
Kimley-Horn has updated the Storm Sewer design using the easement width calculation in the
Design Manual. However, we do request your approval on adjustments to the easement width
calculations for Pipe 4-2 to 4-3 and 4-11 to 4-4. The depth of 4-2 and 4-3 cannot be adjusted due
to potential conflicts between the 48" storm sewer and the proposed waterline design. For the
proposed depth, an easement width of 22.52' is required. With the current design showing a 20'
easement, the whole length of the pipe will still have the 1:1 slopes; however, the first 69' of the
pipe will only have a 7.5' equipment landing. An easement of 14.9' is calculated for pipe 4-11 to
4-4. The current design shows a 15' easement which is greater than the 14.9' required but less
than the 20' minimum. Kimley-Horn requests your approval to keep the easements as designed
due to difficulties with the affected property owners.
(Rev.3) Addressed.
10. Need engineering seal (signed & dated).
(Rev. 2)
Kimley-Horn will submit a signed hard copy set of plans once the County have agreed the
comments have been properly addressed.
(Rev.3) Addressed.
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 approved, and the reasons are provided in the comments below. The erosion control plan content
requirements can be found in County Code section 17-402.

2. Please cross out or remove sheets that are not included with the VSMP from the plan index.
(Rev. 2) Addressed.
3. Provide temporary /permanent seeding and dust control measures throughout the project. 1
(Rev. 2) Addressed.
4. Provide E&SC measures for your "Proposed Underground Detention" system.
(Rev. 2) Addressed.
5. Show staging /stockpile area(s).
(Rev. 2) Not addressed.
Response: Staging/Stockpile area will be included in the SWPPP once the contractor has been
selected and designated a location. This had been discussed with the County Engineer prior to this
comment.
(Rev.3) Addressed.
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;
