Subject: Request for Additional Information
Stormwater Permit No. SW6220902
Wood Lake Phase II Subdivision
Hoke County
Dear Mr. Brown and Mr. Shahbain:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on September 1, 2022. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
1. Per 15A NCAC 02H .1003(4)(e), stormwater runoff that has not been treated in an SCM
shall not be discharged through a vegetated setback, it must be released at the edge of the
vegetated setback and allowed to flow through the setback as dispersed flow. Lismore
Nook appears to have inlets located at the sag point of the roadway that collect the
untreated stormwater runoff from the curb and gutter of the roadway and discharge it to
the culvert/surface water below this road. Please revise as needed.
2. As designed, some of the curb outlet swales appear to be steeper than allowed per 15A
NCAC 02H .1003(2)(d)(ii), maximum longitudinal slope of 5%. Steeper curb outlet
swales are allowable provided that check dams or other devices are provided to slow
down the rate of runoff/encourage infiltration. Please show these devices on the plans and
provide a detail of the check dams or other device.

3. As designed, some of the curb outlet swales do not appear to be sufficiently long. Per
15A NCAC 02H .1003(2)(d)(v), curb outlet swales must be at least 100 ft in length.
Some of the provided swales, such as swales 1, 4, 5, 6, & 11, appear to be shorter than
the minimum required 100 ft. Please revise as needed.
4. Please provide an original signed hard copy of the low-density deed restriction document
with the curb outlet swale language. This document can be found on our website
(https:Hdeg.nc.gov/about/divisions/energy-mineral-and-land-
resources/stormwater/stormwater-program/post-construction-program/post-construction-
forms). NOTE: You may wish to get a second original signed ¬arized hard copy of
this form for the Applicant's records (since an original copy of this form will be needed
when recording this document with the Register of Deeds).
5. Please correct the following issues with the Supplement-EZ Form:
a. Cover Page:
i. Line 2—Please use the project area(35.23 ac) instead of the property area
(35.9 ac).
b. Drainage Area Page:
i. Please complete the LD 1 column (for this project, it will be identical to
the Entire Site column).
c. Low-Density Page:
i. Line 5 —Please revise this value so that it corresponds to the largest
Vactual value for the provided swales.
ii. The 10-year design storm intensity for Ditch#2 is shown in the
calculations as 8.86 in/hr while the other swales have a design storm
intensity of 7.88 in/hr. Please provide a source for the design storm
intensities and revise as needed.
iii. The provided Vactual for Ditch#6 (5.48 fps) exceeds the maximum
Vallowable (5.0 fps) and for Ditch#11, the Vactual (7.21 fps) exceeds the
Vallowable (5.0 fps) (Ditch#11 appears to be a transcription error as the
calculated velocity is within the acceptable range). Please revise as
needed.
iv. Please ensure that the calculations and information in the design table are
provided for the final design conditions, not the temporary stabilization
measures (SC150 matting is a temporary matting).
6. Please provide electronic copies of the USGS topographic map of the site, the signed &
sealed cover page for the calculations, and the property deeds. These items were provided
in the hard copy submission but were not uploaded electronically.
7. Provide PDFs of all revisions, 2 hardcopies of revised plan sheets, 1 hardcopy of other
documents, and a response to comments letter briefly describing how the comments have
been addressed.
a. PDFs must be uploaded using the form at:
https:,[/edocs.deq.nc.gov/Forms/SW-Supplemental-Upload
b. Hard copies must be mailed or delivered to the following address:
i. For FedEx1UPS:
Jim Farkas
512 N. Salisbury Street, Office 640E
Raleigh, NC 27604
ii. For USPS:
Jim Farkas
1612 Mail Service Center

iii. Hand Delivery:
Please reach out to me prior to hand delivering a submission to make
sure that I (or someone else in my group) will be able to receive the
submission. Do not leave the package in the foyer with the
security guard.
NOTE: Hard copies should not be sent to a Regional Office. Doing so
will delay the review process and the submission package may be lost
while being sent from the Regional Office to me in the Central Office.
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 December 30, 2022, or
the application will be returned as incomplete. The return of a project will necessitate
resubmittal of all required items, including the application fee. Please reference the State
assigned project number SW6220902 on all correspondence.
If you need additional time to submit the information, please submit your request for a time
extension to the Division at the contact below. 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.
If you have any questions concerning this matter please feel free to contact me at
