Dear Mr. Koch:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on October 23, 2019. 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 complete a low density supplemental form. The form can be found by
downloading Supplement EZ at the Stormwater Design Manual website and selecting
low density.
2. Please delineate any wetlands on site or a note that none exist [I 5A NCAC
02H .1042(g)(iii)]. If the hatched area on the plans represents wetlands please add a note
indicating this and the individual/entity who made the determination.
3. Lots 4, 5, and 6 as shown on the Existing Conditions & Demolition Plan (C2.0) are
shown as being owned by Timber Creek Estates. A deed, lease, or purchasing agreement
must be provided to indicate that the applicant has a legal right to develop these
properties.
4. The ditch details on Sheet D4.0 show that the side slopes of the roadside ditches are
steeper than 3: 1. Please revise the plans and details to show that the side slopes are no
steeper than 3:1 [15A NCAC 02H .1003(2)(c)(i)].
5. Please add a note to the ditch details on Sheet D4.0 to show that the ditches must be
vegetated and provide calculations showing that the ditches will not have erosion during
the peak flow from the 10-year storm in their permanent vegetated condition [I5A NCAC
02H .1003(2)(c)(ii)].
