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. 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. Please provide an updated registration statement and overall coverage map showing the total
acreage to be covered by this plan/permit. The current permit is VARlOK793 and is for 54.39
AC. Is the new total 63.29 AC since this plan is adding 8.9AC? Rev. 1: Comment not
addressed. Per meeting on July 9`s, 2020, applicant is sending new registration statement
and coverage map which will cover this project and WPO20200004 which is anticipated to
be approved at a similar timeframe. If not, a registration and map just for this plan mast be
submitted. Rev. 2: Comment addressed.
B. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17-404.
1. Please provide a PPP to be inserted in the S WPPP. Rev. 1: Comment addressed.
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. Professional engineering seal should be signed and dated. The calculations packet should also
have a signed and dated seal. Rev. 1: Comment addressed.

2. Topography should be at lest field verified within the last year. The cover sheets references a
2018 date. Rev. 1: Comment addressed.
3. Preserved slopes and the greenway cannot be disturbed as shown. Only those shown on approved
ZMA 2015-007 as greenway impacts and preserved slope impacts may be disturbed. Blocks 3 &
4 did not appear to show any impacts on the ZMA. This applies to the proposed sediment basin B.
The Code of development section 2.4.1 also states that SWM facilities may not be in the
greenway. Please note that sediment BasmB/wet pond B was not fully reviewed since the location
and design will change based on this comment. Rev. 1: Comment addressed.
4. [Sheet 6] Engineering believes the slopes shown below are steeper than 2:1 in the field. Please
verify.

I /: / ) Rev. 1: Comment addressed.
Ensure the greenway is correctly labeled throughout the plan. It is not a 100 ft WPO buffer. It is a
proposed greenway. Rev. 1: Comment addressed.
Ensure all approved plan numbers are shown, and accurately depicted. For example, the
"approved ice rink" is WPO201800050 and it is not approved. Rev. 1: Comment addressed.
What is the extended area below? Is it for maintenance/access? This was not shown on the ZMA.
It was only a primitive trail. Also, this parcel would need to be added to the SWM agreement.

9. All applicable plans will need to be amended to show the change with the removal of the level
spreaders, pond 4 changes, etc. This can be a simple sheet with a summary referencing the
changes and this plan number. Engineering can assist with gathering all of these plans. However,
it is important that they all get amended so when it is time for bond release, the most acute

approved designs are shown. Rev. 1: Comment addressed. This will be a condition at time of
approval.
10. What approved plan shows the removal of LS-10 as shown in the tables on Sheet 19? Rev. 1:
Comment addressed.
11. Rev. 1: Provide an interim sheet or note showing grading/E&S if the ice rink plan is not
approved or built. It is currently under review, not approved. WPO201800050,
SDP201800049 and SUB201800115 are not approved. Rev. 2: Comment addressed.
12. Rev. 1: Please see attached zoning ordinance update that now applies to all grading. Ensure
this site meets all requirements. This applies only to new disturbed areas, not already
approved areas, for example, around pond 4. Rev. 2: Comment addressed.
13. Rev. 1: [ Sheet 201 It is unclear where the new Pond B is located in this chart. Please clarify.
Rev. 2: Comment addressed.
14. Rev.l: [Sheet 151 Please label the SWM facility / access easement. Believe it is shown, but
not labeled. Rev. 2: Comment addressed.
15. Rev. 1: [Sheet 181 Please show the overall location of this LS. Those unfamiliar with the
plans have no context of its location. Rev. 2: Comment addressed.
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. [Sheet 4] How much area is going to the single inlet shown below? It appears to be more than 1
ac, which is the maximum drainage area allowed per 3.07 in the VESCH. It is understood that it
goes to the sediment basin, but it also needs to function and not get clogged.

Engineering suggests showing the Phase II E&S for Block IA along Salamander road, unless the
applicant intends to submit a separate WPO plan for that Block. For example, show inlet
protection for any inlets. Rev. 1: Comment addressed.
Please show the proposed silt fence and tree protection in a dark linetype. It currently appears to
be the same as existing items. Rev. 1: Comment addressed. Linetype is still light, but label says
proposed.
[Sheet 14] Is the note shown below supposed to say amendment 2? Or is it supposed to say
approved amendment 1?

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.
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.
