Subject: CERTIFICATION OF COMPLIANCE
with Stormwater Regulations
Stormwater Project No. 940916
Summerlin Falls
New Hanover County
Dear Mr. Stephens:
This Certification is pursuant to the application for Summerlin Falls received on
September 16, 1994, with additional information received on October 6, 1994. Staff review of the
project plans and specifications has determined that the stormwater control system as proposed for
Summerlin Falls will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1003(i).
The runoff from 344,600 square feet of impervious surface area will be treated in a detention pond sized
to achieve 90% reduction in Total Suspended Solids.
Any modification of the plans submitted to and approved by this Office or further development
of this site regardless of the fact that the modification may be less than 1 acre, will require an additional
Stormwater Submittal/Modification and approval prior to initiation of construction. Modifications include
but are not limited to; project name changes, transfer of ownership, redesign of built-upon surfaces,
addition of built-upon surfaces, redesign or further subdivision of the project area.
This Certification shall be effective from the date of issuance until rescinded. The project shall
be constructed and maintained in accordance with the plans and specifications approved by the
Wilmington Regional Office. This Certification does not supersede any other permit or approval. The
developer is responsible for obtaining any and all permits and approvals necessary for the development
of this project. This could include the Division of Coastal Management under CAMA requirements, the
Division of Environmental Management under Wetland 401 Water Quality Certification and/or a Dredge
and Fill Permit and/or a Sewer Extension/Collection Permit, U.S. Army Corps of Engineers 404 Wetland
Permit, NPDES Stormwater Permit if disturbing five acres or more, local County or Town Agency
permits under their local ordinances, or others that may be required.

---------------------------------------
A professional engineer must certify that the stormwater system has been installed in accordance
with the approved plans and specifications upon completion of construction. The attached certification
should be received by this Office within 30 days of completion of construction.
The detention pond must be constructed in it's entirety, operational for it's intended use, and
permanently vegetated prior to the construction of any impervious surfaces proposed as a part of the
project, except roads.
If you have any questions concerning this matter, please call Steve West or me at [phone].

outlet structure is working properly and is not clogged with debris. Remove any accumulated
sediment or debris. Any signs of erosion or deterioration of the pond side slopes or any other feature
must be repaired before the next storm event.
B. The depth of the pond will be checked every six months to determine the depth of the
permanent pool. The pond will be cleaned out when silt deposits reduce the depth of the permanent
pool below 5.63 feet.
C. Collection basins and piping will be checked every six months and kept clear as
necessary.
