Reviewers: Emily Cox
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.
1. Registration statement must be filled out and signed. Rev. 1: Comment not addressed.
2. Section 9 (signed certification) must be signed. Rev. 1: Comment not addressed.
B. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17-404.
1. No comments.
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. Nutrient credits must be purchased before plan can be approved. Please contact Ana
Kilmer(akilmer&albemarle.org or 434-296-5832 ext 3246 before purchasing the credits. Rev. 1:
Comment not addressed.
2. SWM Maintenance agreement must be recorded before plan can be approved. Nutrient credits
must be purchased before plan can be approved. Please contact Ana
Kilmer(akilmer@albemarle.org or 434-296-5832 ext 3246 to start this process. Rev. 1: Comment

not addressed.
3. A plat and deed showing the SWM facility easement must be recorded before the plan can be
approved. Rev. 1: Comment not addressed.
4. Clearly show the extent of the SWM Facility easement. Rev. 1: Please label this easement to be
SWM facility easement. Ensure this matches the final site plan.
5. Provide a detail of the SWM facility. Will there be a trash rack? What size are the
manholes/openings? Are they accessible for maintenance? Are there any special installation
instructions? Rev. 1: Comment not addressed.
6. Provide maintenance requirements for the SWM facility on the plans. Rev. 1: Comment
addressed.
7. Provide the following checklist on the plans:

ty Development/forms/applications/WPO VSMP Construction Record Drawings
Policv 23Mav2014.pdf Rev. 1: Comment addressed.
8. Please double check all calculations. Page 7 of the calculations does not match Sheet C1.6 (1.03 vs
1.06 etc). Rev. 1: Comment addressed.
9. Please double check the DA for inlet 118. Rev. 1: Comment addressed.
10. Are the storm pipes sized for the future development? It is clear the SWM facility was sized/routed
for it, but the storm calculations do not appear to include the future area (the DA for 112 is 069 c
factor for future building area). Rev. 1: Comment not addressed. The pipe and inlet
calculations should include the future development if they will eventually handle runoff
from that area. For example, 204-202-SWM A. Where will the future development tie in? If
it goes directly to SWM A, then no calculations necessary and comment is addressed.
11. 0.5% is the minimum storm pipe slope. The calculations show some pipe slopes less than 0.5%.
Rev. 1: Comment not addressed There is a slope of 0.49% from 101-102.
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. A soils type map was not apparent on the plans or in the calculations booklet. Rev. 1: Comment
addressed.
2. Please show a wash rack at the construction entrance. Rev. 1: Comment addressed.
3. Please show mulching anywhere there is TS or PS. Rev. 1: Comment addressed.
4. Per PgIII-72 of the VESCH, please show there is a 2:1 length:width flow ratio for the sediment
trap flow path. Rev. 1: Please add a detail for the proposed baffles and note that they must
extend from the bottom of the trap to 6" above the riser.
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;
