A. Stormwater Pollution Prevention Plan (SWPPP)
Justin M. Shimp
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. This project
is subject to approved SP201800016.
This SWPPP is disapproved, and the reasons are provided in the comments below.
1. Notice of general permit coverage
2. Nature of the activity (use/development of the site, not the E&S controls). It should refer to
redevelopment of the site, number of units, parking, private roads, support structures and
stormwater controls. The narrative provided properly belongs in Section 4.
3. Qualifications and contact information for qualified personnel
4. Signed certification
5. Delegation of authority
6. The cover and site plan sheets state that 36 units will be constructed, although it appears that 38
units will be constructed. Please revise wherever it appears.
7. Please include the WPO number above on the cover sheets of the plan, SWPPP and calculations.
8. Please note that additional comments may be generated based on the response to the comments
provided.
B. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a
SWMP. This plan is disapproved.
1. Show permanent drainage easement recording information on all parcels crossed by the Al-A-4
stormwater conveyance piping and structures. 17-304.E.
2. Provide Albemarle County General Construction Notes for Stormwater Management Plans (three
notes).
3. Provide buoyancy calculations for the sedimentation basin riser and the anti -floatation details.
4. Revise the principal spillway detail to show the base (see the previous question).
5. Provide calculations that demonstrate compliance with SP201800016, including hydrographs,
routing calculations and other necessary documentation that the proposed stormwater system is

adequate to manage the 25-year storm without downstream flooding.
C. 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. Sheet C2 has overlapping labels, making them difficult to read. Please revise.
2. Sheet C2 does not show all of the disturbed area (omits the sanitary sewer and stormwater piping
offsite). Please revise.
3. Sheet C7 Offsite Areas narrative appears to have a typo. Please clarify.
4. Sheet C8: Note on Sheet C2 states that driveways are to remain until Phase 2 of construction. This
sheet (Phase 1) shows the sediment basin in conflict with the driveway. Revise to correct conflict.
5. Detail references on Sheet C8 appear to refer to incorrect detail or sheet numbers. Please revise.
6. Sheet C8 appears to have a stray SF symbol SW of Agnes Road. Clarify or delete.
7. Sequence of Construction does not mention the Stormtech system construction. Please include the
detention basin in the sequence of construction.
D. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17-404. This plan is
disapproved, for the reasons provided below.
1. If fueling will occur onsite, provide location and address it in the plan.
2. On the Phase 2 sheet, only 10 feet of width between the dike and edge of pavement is provided to
the dumpster, portajohns and rinse supply area. The extent of the RWD is not provided. Please
clarify whether that section of DD is RWD and that service trucks will not damage the dike.
3. Table in section C:
a. Show the location of the leakproof container for concrete washout.
b. Show dewatering sites on the plan, and relationship to E&S and/or PPP measures.
c. Show material delivery areas on the plans.
d. Solid waste disposal area is downslope of hill; stormwater from this location bypasses all
stormwater BMPs. Please show protection of the site from upland runoff and PPP
measures for leakage and spills.
e. Vehicle washing area(s) not shown on the plans. If the activity will occur, show on the
plans how the wash water will be handled. Detail for "Paved Wash Rack" (Sheet C11)
shows wash water draining to trapping device. Therefore, provide a trapping device in the
vicinity of the construction entrance.
£ Show a contractor laydown/storage area on the plan.
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.

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;
