Reviewer:
David James [djames2@albemarle.org]
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.
1. Registration Statement:
a. Sec.l B. - Check box
b. Sec.11 F. -Change to Albemarle County
c. Sec.11 H. - Check box
d. Sec. III -Complete prior to permit issuance
e. Sec. V - Sign & date
2. Complete Section 9. Signed Certification prior to plan approval.
3. Complete other sections prior to pre -con.
B. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17-404.
1. Appears complete; revise as needed.
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.
1. Show the Forest & Open Space easement(s) areas to be protected. According to VRRM
4.13ac F/OS protected.
2. A swm narrative will need to be included on the plans.
3. 1 would prefer that information on the type and location of stormwater discharges,
predevelopment and postdevelopment drainage areas be shown on the plans rather than
separately in talc. packet.
Engineering Review Comments
Page 2 of 3
4. Calculations packet:
a. Pg. 16 - Revise title of map to "POSTDEV...".
b. Your pre- & post- development drainage area totals should match.
c. It's not clear from the maps how you are reducing offsite impervious area (1S/8S)
postdevelopment.
d. Label/show offsite & onsite drainage areas.
e. Pg. 24 -
i. Please cite the page numbers.
ii. Clairfy why you are subtracting Max Qd, from the Qpmde ? Max Qdev
determined (0.15cfs) is less than the Achieved Reduction (0.89cfs).
iii. Use the Energy Balance (offsite) equation. Consult the Plan reviewer
SWM participant guide.
f. Please clarify: On pg. 24 you state you're meeting flood protection under 66-
C(2)b, but on pg. 3 for flood protection it looks like your trying to meet 66-C(1).
i. You're not showing you meet 66-C(2)b, Qpost>Qpre.
g. VRRM - Please use New development spreadsheet. The parcel is undeveloped.
h. Provide inlet drainage area map and assumed values to match calc. table.
i. Provide channel adequacy/protection is met from the Al discharge point to
outfall natural channel (i.e. portion of ex. manmade channel). 66-13(1)a
and Energy Bala ce must hP ....et there
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. Cover -
a. Provide date(s) of LIDAR data.
b. Provide date of field verification of topography & existing conditions.
2. Please show LOD on the existing conditions sheet.
3. Show demolition operations.
4. Show existing treeline.
5. Show accurate horizontal depth (batter) of retaining wall.
6. Show geogrid extent of retaining wall.
7. Label TW/BW elevations at each bend and wall ends.
8. Tie contour lines along new road to the retaining wall.
9. Note: Please submit retaining wall design & computations with the site plan. Separate
building permit required.
10. Show all proposed contours at 2' intervals.
11. Reduce grade to 2:1 or less adjacent to lot 1.
12. Provide B/M (VAESC HB, 3.36) between lots 5 & 6, and adjacent to lot 1.
13. Where grade over 3:1 provide low -maintenance (not grass) groundcover.
14. Show a staging and stockpile area. Show SF around stockpile.
15. Show temporary construction easement for offsite improvements.
16. Provide letter of permission from VDOT for work in the ROW prior to disturbance.
17. Provide volume estimate of cut & fill balances.
Engineering Review Comments
Page 3 of 3
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, a joint VSMP and grading
permit will be issued by the County so that work may begin.
