Subject: Zone 8-Kimmel Farm Elementary and Flat Rock Middle School
Ms. Homewood,
I am writing to inform you that Winston Salem/Forsyth County Schools have addressed the last issue with
bringing Stormwater Permit No. SW4080701 back into compliance. "There was an unapproved gravel road
constructed that made the site stormwater calculations inaccurate. With the help of the Design Engineer,
Kevin Davie, Allied Design, Inc., we were able to reduced the approved walking track from 27.5' down to
25'. This allowed us to keep the gravel road at 6' for a walking path and an access road for vehicle track for
maintenance work needed in that area. The changes to the walking track and the gravel road happen
within that same basin area, therefore bringing the previous approved stormwater calculations to remain the
present accurate calculations. Pictures of the work completed are available upon request, All disturbed
areas were seeded and strawed.
If there are any questions, please contact us at the information listed above.

Inconsistencies and incomplete reported on the supplement, for example distance from
bottom of bioretention cell to SHWT is 728.05 feet, SHWT not reported, peak flow
calculations not provided, incomplete information provided under the section "additional
information."
Failure to provide sealed, signed & dated calculations for the proposed BMPs.
For bioretention cells the volume in excess of the design volume bypassed shall be evenly
distributed across a minimum 30 feet long vegetated filter strip.
Please see checklist on our website to help check that your re -submittal includes all necessary
items. It can be downloaded from http://h2o.enr.state.ne.us/su/documents/checklistrev-1.pdf.
Please note that this request for additional information is in response to a preliminary review.
The requested information should be received by this Office prior to August 15, 2008, or the
application will be returned as incomplete. The return of a project will necessitate resubmittal of
all required items, including the application fee. If you need additional time to submit the
information, please mail or fax your request for a time extension to the Division at the address
and fax number at the bottom of this letter. The request must indicate the date by which you
expect to submit the required information. The Division is allowed 90 days from the receipt of a
completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to
enforcement action pursuant to NCGS 143-215.6A.
Please reference the State assigned project number SW4080701 on all correspondence. All

Stormwater Project No. SW4080701
Zone 8 School Property -Proposed Elementary and Middle Schools
Ebert Road Site, Southfork Township, Forsyth County
Dear Mr. Tusing:
The Division of Water Quality Central Office received a Stormwater Management Permit
Application for the subject project on July 3, 2008. A preliminary review of that information has
determined that the application is not complete. The following information is needed to continue
the stormwater review:
1. As previously noted in our letter dated May 3, 2008, to meet the low -density the project
must meet the requirement to transport stormwater runoff primarily through vegetated
conveyances. Low -density projects should not have a discrete stormwater collection
system as defined by 15A NCAC 2H.1002(18). Under 15A NCAC 2H1002(18) a
stormwater collection system means any conduit, pipe, channel, curb or gutter for the
primary purpose of transporting runoff. It appears that all or at least most of the
stormwater runoff from,the proposed elementary and middle school buildings is being
conveyed through a discrete stormwater collection system. Discrete stormwater
collection systems must include stormwater controls designed to achieve 85% average
annual removal of total suspended solids for the runoff for the appropriate design storm
with a minimum of 48 hours drawdown time, but not more than 120 hours, and a
discharge the storage volume at a rate equal to or less than the predevelopment discharge
rate for the one-year, 24-hour storm.
2. As previously noted in our letter dated May 3, 2008, a legend was provided.
3. Failure to delineate the drainage area to each stormwater BMP. As previously noted in
our letter dated May 3, 2008, drainage areas are not delineated on final grade.
4.. Failure to provide the Season High Water Table (SHWT), as previously noted in our
letter dated May 3, 2008. For BMPs that require a separation from the seasonal
high-water table, the separation shall be provided by at least 12 inches of naturally
occurring soil above the seasonal high-water table. Bioretention facilities shall not be
used where the seasonally high water table less than 2 feet below bottom of BMP.

RE: Drawing Revisions
Post -Construction Stormwater Permit Application
Zone 8 Schools — Ebert Road site
ADI # 08-013
Per our phone conversation last week, and your email message on Friday, we have revised
-ti the two enclosed drawing sheets. Specifically, we have addressed 4 of the 5 items in
question, although we did not make any specific recommendations with regards to the rain
barrels, for a harvesting program. While I asked you about the possible consideration for
using rain barrels in-between two wings, I'm not currently comfortable with the level of
attenuation that we can achieve, nor the treatment benefits. We will continue to explore
improvements that the barrels may offer, but will not include them at this time in the
management plan.
We believe the other items to be adequately addressed, but are still available to make
revisions or corrections as necessary.
Thank you so much for your continued assistance with this permitting effort.

'fhe Division of Water Quality Central Office received your resubmitted 5tonnwater Management Permit
Application on August 22, 2008. Per our discussing this morning, a preliminary review of that information
has determined that the application is not complete. The following information is needed to complete the
stormwater review and issue a permit:
l) Direct the roof leaders that current tie into box 27 to the open area just beyond the walking track.
2) Eliminate Box 18 or move further back and shorten the line between Box 4 and 18 to take advantage
of the open space between the two buildings.
3) Provide cross sections of the parking lots and parking lot islands.
4) Look at eliminating box I IA and the line between Box 10 and box 1 IA. As we discussed this will
depend on the flow currently coming to box 10. Use your best professional judgment.
S) To reduce peak flows to the maximum extent practical investigate the use of rain water harvesting
where piped conveyances can not be eliminated. I've attached a draft document on rainwater
harvesting. Use your best professional judgment.
This request for additional information is in response to a preliminary review and pursuant to our
discussions on August 29, 2008. The requested information should be received by this office by
