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.
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. Please provide an updated registration statement that includes the added area from this plan.
Please use the newest form (attached to these comments). Rev. 1: Please double check the
areas. The approved area for the borrow area is 2.36 AC. Your map shows 3.32 AC. The
current VAR permit is for 13.15 AC on site and 2.36 off site. Your registration statement
and coverage map should match this, with only adding new project areas(16.99AC). Rev. 2:
Comment not addressed, but discussed on phone call and will be resubmitted. Ensure
proposed start date is updated as well. Rev. 3: Comment addressed.
2. Is this a balanced site? Per new DEQ regulations, if anything is taken offsite, it must be shown on
the registration statement. Rev. 1: Comment not answered. Rev. 2: Comment addressed.

when this is completed. You can attend this site visit. Rev. 1: Comment addressed.
8. If the area of the level spreader and the conserved open space must be graded to achieve flat
levels and required slopes, this may need to be a vegetated filter strip or have compost amended
soils. Rev. 1: Comment addressed.
9. The county is asking the County Attorney to verify that these easements for the level spreader
conserved open space can be applied on top of the existing forest & open space easement. Rev. 1:
Comment addressed.
10. [calculations packet, page 39] Since this water quality summary relies on other plans, they must
be approved before this plan can be approved (WP02 0190 0 02 7connector road, and
W P02 016 0 0 0 6 9 Vue amendment). Rev. 1: Comment addressed.
11. Per 9VAC25-870-66, concentrated stormwater flow shall be released into a stormwater
conveyance system and shall meet the criteria in subdivision 1, 2, or 3 of this subsection. Ensure
all of the outfalls go to a conveyance system(channel), in addition to meeting the water quantity
criteria. (energy balance, etc). Rev. 1: Comment addressed.
12. Signed and sealed engineering wall plans must be provided for walls that are part of a SWM
facility before plan approval. Rev. 1: Comment addressed. However, please know that
retaining wall plans will be necessary for site plan approval.
13. Ensure tops and bottoms on all walls are shown. Rev. 1: Comment addressed.
14. Rev. 1: See attached letter from Megan Nedostup. This plan cannot be approved until that
issue is resolved. Rev. 2: Comment not addressed. Rev. 3: Comment addressed.
15. Rev. 1: [Calculations packet and sheet 161 Please be sure to include the borrow area
nutrient credits in the calculations showing the 75% coverage. The total currently
purchased is 6.97 + 0.18=7.15 lb/yr. This was from WPO201900027 and WPO201900027
amendment 1. Rev. 2: Comment addressed.
16. Rev. 1: [Calculations packet and sheet 161 The 0.27 nutrients purchased do not count
towards this development. They were for another plan(WPO2016000069) and are
independent of the requirements for this plan. Therefore, they cannot be subtracted from
the removal rate required. Rev. 2: Comment addressed.
17. Rev. 1: Please remove the last sentence on the cover sheet regarding the grading and
drainage plan. The site plan and WPO plan grading must match. Rev. 2: Comment

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

5. [Sheet 6&7] Per the VESCH, 3.09, the maximum drainage area to diversion dikes is 5 ac. It
appears 6.92 AC is draining to the most northern one on site. Consider a clean water diversion to
keep offsite water from the north from being contaminated on site. 8.12 Ac is draining to SB C &
the diversion dike. Rev. 1: Comment addressed.
6. [Sheet 6&7] For diversion dikes over 300 ft, provide outlet protection going into the sediment
basins/traps. This is due to water concentrating after 300 ft [per TR-55]. Rev. 1: Comment
addressed.
7. [Sheet 6] Please extend silt fence around sediment basin D adjacent to rambling brook lane. Rev.
1: Comment addressed.
8. [Sheet 10] McComb Street should have inlet protection, at least the inlets closest to the
disturbance, in case the silt fence fails. Rev. 1: Comment addressed.

name of the specific detail so it will be clear where to find the information. Rev. 2:
Comment addressed.
E. Mitigation Plan
1. Ensure all disturbance in the buffer is accounted for. Particularly, the level spreader and
conserved open space may need more disturbance than shown in order to achieve the required
grades and slopes. Rev. 1: Comment addressed.
2. Rev. 1: Please show the 50 It buffer line to ensure that no disturbance is in the inner (closest
to the stream) 50 ft except the storm outfall pipes. Rev. 2: Comment 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;
