Subject: Request for Additional Information
Stormwater Permit No. SW6191005
Dining Facility (DFAC), SOTF
Cumberland County
Dear Mr. Saltsman:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on October 29, 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 verify that the provided latitude and longitude are correct (Section I, 4). It appears
that the project is about a half of a mile away from the provided coordinates.
2. Please change the applicant/organization to "Director of Public Works (DPW)" (Section
III, 1, a).
3. Please use the project area of 2.25 acres for the total property area, total project area, and
percent impervious area calculation (Section IV, 4, 7, & 8). Including the existing BUA
that will be replaced 1:1 with proposed BUA and the disturbed pervious areas will not
impact State stormwater quality requirements for this project.
4. Please dimension the proposed BUA so that the provided values may be verified (Section
VI, 8, j).
5. Please delineate the wetlands on the plans or provide a note stating that no wetlands exist.
Provide documentation of the qualifications and identity of the individual who made this
determination (Section VI, 8, m).
6. There is an existing stormwater permit, SW6110105, that was applied for when the
dining addition, gym addition, and CDD/signal addition were added to this building.
There appears to be some overlap between the area covered under that permit, and the

area that will be covered under this permit, specifically where the new building addition
is being proposed. Please show the SCMs associated with SW6110105 and their drainage
areas on the plans. If these facilities are being impacted by the proposed development, the
loss of treatment must be made up for by the proposed SCMs (Section VI, 8, n).
7. Please provide some form of pretreatment for the stormwater bypassing the grass swales
that enters infiltration facilities 2 & 3 (Infiltration MDC 4).
8. Please provide cross -sections of the proposed infiltration systems in accordance with H15
NCAC 02H .1042(2)(h).
9. Please make the following corrections to the Supplement-EZ Form:
a. Cover Page Sheet
i. Line 2 — See prior comment.
b. Drainage Areas Sheet
i. Entire Site Column
1. Line 5 — This is the total amount of BUA that will be present, post -
construction, within the project area. Since there are no subdivided
lots, this value should equal Line 7 of this column.
2. Line 7 — This is the new (net increase) in BUA that will be placed
within the project area. This value should be equal to the sum of
the items in Line 10 of this column.
3. Lines 8 & 9 — Since this column is an accounting of everything
within the project area, there should not be any off -site areas.
4. Line 13 — Any impervious area that will remain post -construction,
like the Dumpster pad, should go on this line.
ii. Infiltration Basin Columns
1. Line 5 — This is the total amount of BUA that will be present, post -
construction, within the drainage area to each facility. Since there
are no subdivided lots, this value should equal Line 7 plus Line 9.
2. Line 7 — This is the new (net increase) in BUA that will be placed
within the drainage area to each facility and also within the project
area. This value should be equal to the sum of the items in Line 10.
iii. General
1. Do not use the actual volumes that can be stored in the facilities on
the Infiltration System Sheet, use the values from Line 18.
c. Infiltration System Sheet
i. Line 2 — See prior comment.
ii. Line 16 — Answer this item.
iii. Line 44 — See prior comment.
iv. Line 45 — Recalculate these values using the design volume, not the
volume that can be held in the facilities.
10. 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:
