The PPP content requirements can be found in County Code section 17-404.
1. No objections. Be sure to insert into approved plan into the SWPPP.
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. Please combine the Erosion Control Plan and the SWM Plan into one plan set. That plan should
have the WPO201700022 number on it and have the title "VSMP Plan". Rev. 1: Comment
addressed.
2. Nutrient credits must be purchased before plan can be approved. Contact Ana Kilmer before
credits are purchased. Rev. 1: Comment not addressed. Rev.2: Please remove sheet C-504
from the plan set. A simple note that 0.77 Ib/yr will be purchased is fine. Coordinate with
Ana Kilmer for the purchase of nutrient credits. Rev 3: Comment addressed.
3. Review the area of disturbance. Grading and disturbance appears to go outside the limits at the
Greenbrier Dr. entrance and at the comer of Greenbrier Dr. & Westfield Rd. If disturbance during
construction goes beyond the permitted limits, a stop work order may be issued until a DEQ
permit is issued. Rev. 1: Comment addressed.
4. Information on Sheet C-405 was cut off Please review the sheet layout and ensure all
information is legible. Rev. 1: Comment addressed.

8. Provide a map showing the impervious area and managed turf area within the disturbed area used
for the water quality calculations. Rev. 1: Comment addressed.
9. Provide the state -storage calculations/routings for the SWM pond as well as the emergency
spillway design. Rev. 1: Comment addressed.
10. Provide a detail for the proposed retaining wall in the SWM pond.Rev. 1: Comment addressed.
Please note that a building permit is necessary for retaining walls over 3 ft. in height. Rev.
2: Comment noted.
11. Label the easement around the SWM pond, "SWM facility easement". This will need a SWM
maintenance agreement as well as a deed/plat. Contract Ana Kilmer for the SWM agreement.
Rev. 1: Comment not addressed. Plan cannot be approved until the SWM Agreement is
recorded. The Final Site Plan cannot be approved until the plat/deed are recorded. Rev. 2:
Comment addressed.
12. Storm pipe from 5A to 5 is labeled as sanitary. Also, the pipe from 5A to 5 is labeled as 15" in
the detail, but 18" in the profile and the storm pipe calculations have a I and 8131. These appear
to be mis-labeled. Please review and revise. Rev. 1: Comment addressed.
13. Label the strength class of the proposed storm pipes on the profile. Also, ensure that all utility
crossings are shown. Rev. 1: Comment addressed.
14. Provide a map showing the drainage to each storm structure. Rev. 1: Comment addressed.

17. Rev 1: The velocity from Ex. 9 to 8B is high. The County prefers velocities to be a maximum
of 15ft/s. However, since this is an existing pipe, please confirm there is no current erosion
or scouring in the pipe. Rev. 2: Comment addressed.

with a completed application form.

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
Engineering Review Comments

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, 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;
