Subject: Request for Additional Information
Stormwater Permit No. SW4201101
Heritage Oaks, Section II — Residential Subdivision
Forsyth County
Dear Alex Carter:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on November 19, 2020. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
1. Please delineate any wetlands onsite or add a note that none exist [15A NCAC
02H .1042(2)(g)(ii)].
2. Sheet C2-5 shows a slope on the roadside ditches as 2: 1. The maximum allowable side
slope for vegetated conveyances on low density projects is 3:1 [15A NCAC
02H .1003(2)(c)(i)].
3. The low density only allow for a minimal amount of non -vegetated conveyances for
erosion protection or piping for driveways. Sheet C4-0 show areas where runoff is being
piped away from the roadways through 20' drainage easements before being discharged.
The conveyances in these drainage easements should use vegetated conveyances rather
than piping to meet the low density requirements [15A NCAC 02H .1003(c)].
4. Provide pdfs of all revisions, 2 hardcopies of revised plan sheets, and 1 hardcopy of other
documents. Pdfs must be uploaded using the form at:
hgps:Hedocs.deg.nc.gov/Forms/SW_Project Submittal
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 January 7, 2021, 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 SW4201101 on all correspondence.
