Subject: CERTIFICATION OF COMPLIANCE
with Stormwater Regulations
Stormwater Project No. SW8 940418
North Chase - Lakemoor
New Hanover County
Dear Mr. Clark:
The Wilmington Regional Office received the revised Stormwater Submittal for North Chase -
Lakemoor on February 22, 1995, with final information on March 13, 1995. Staff review of the plans and
specifications, including the statement of intent to deed restrict the allowable built -upon area to 2,366
square feet for each of the 45 lots shown on the approved plan, has determined that the project as proposed
will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1003(a)(3), and the Third
Directive, Curb and Gutter Requirements, dated November 15, 1989. The revision consists of the vertical
realignment of Trotter's Court so that all of that runoff drains to Swale #5.
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 as shown on the
approved plans.
This Certification shall be effective from the date of issuance until rescinded.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.

Clark Construction Co., Inc., has warranted that said improvements
will be performed in a proper and workman -like manner, and that
saI id improvements will meet all federal, state and local
regulations and that the same will be inspected and approved by the
appropriate authorities. The Homeowners Association will perform
routine inspection and maintenance as outlined below. Dues will be
established at a level sufficient to fund the required maintenance
personnel. As a minimum, the required maintenance procedures will
include:
(1) Ensure that grass is mowed a minimum of one (1) time
every ten (10) days during the growing season.
pev- £S 6-9-9y
