The Division of Energy, Mineral, and Land Resources (DELMR), received a complete Stormwater
Management Permit Application for the subject project on May 19, 2017. Staff review of the plans and
specifications has determined that the project, as proposed, will comply with the Stormwater Regulations
set forth in Title 15A NCAC 2H.1000 rules. We are forwarding Permit No. SW3170504, dated June 09,
2017, for the construction, operation and maintenance of the subject project and the stormwater system.
This permit shall be effective from the date of issuance and shall be subject to the conditions and
limitations as specified therein, and does not supersede any other agency permit that may be required.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to

' Dry Detention Pond Maintenance Requirements
Important maintenance procedures
- The drainage area will be managed to reduce the sediment load to the dry extended detention basin.
- Immediately after the dry extended detention basin is established, the vegetation will be watered twice weekly if needed
until the plants become established (commonly six weeks).
- No portion of the dry extended detention pond will be fertilized after the first initial fertilization that is required to establish
the vegetation.
- The vegetation in and around the basin will be maintained at a height of approximately six inches.
- If cracks, seepage, or woody vegetation is present, consult a dam safety expert for a dam inspection.
The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
After the dry detention basin is established, it will be inspected quarterly. Inspection activities shall be performed as follows and
any problems identified will be remediated immediately per the table below.

I Sand Filter Maintenance Requirements I
Important maintenance procedures:
- The drainage area will be carefully managed to reduce the sediment load to the sand filter.
- The sedimentation chamber or forebay will be cleaned out whenever sediment depth exceeds six inches.
Once a year, sand media will be skimmed.
The sand filter media will be replaced whenever it fails to function properly after maintenance.
The sand filter shall be inspected quarterly and within 24 hours after every storm event greater than 1.0 inches (or 1.5
inches if in a Coastal County). Records of operation and maintenance will be kept in a known set location and will be available
upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.

7. Total Property Area (4) - Total Coastal Wetlands Area (5) - Total Surface Water Area (6) = Total Project
Area4:19.85 acres
Total project area shall be calculated to exclude the following: the normal pool of impounded structures, the area
befrveen the baltks of streams and rivers, the area below the Nornal High Water (NHW) line or Mean High Water
(MHW) line, and coastal wetlands landward from the NHW (or MHW) line. The resultant project area is used to
calculate overall percent built upon area (BUA). Non -coastal wetlards landward of flue NHW (or MHW) line tray
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 15.72 %
9. How many drainage areas does the project have? 1 (For high densihj, count ] for each proposed engineered
stormwater BMP. For lozo densihll and other projects, use ] for the whole properhlt area)
10. Complete the following information for each drainage area identified in Project Information item 9. If there
are more than four drainage areas in the project, attach an additional sheet with the information for each area
provided in the same format as below.
