Subject: Stormwater Permit No. SW8 021101 Modification
North Brunswick Industrial Park, High Density Project, Brunswick County
Dear Mr. Dale
The Wilmington Regional Office received a modification to Stormwater Management Permit
Application for North Brunswick Industrial Park on August 31, 2006 with additional information received
on October 12, 2006. 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 21-1.1000. We are
forwarding Permit No. SW8 021101 Modification dated November 6, 2006, for the construction of the
subject project.
This permit shall be effective from the date of issuance until November 6, 2016, and shall be
subject to the conditions and limitations as specified therein. Please pay special attention to the
Operation and Maintenance requirements in this permit. Failure to establish an adequate system for
operation and maintenance of the stormwater management system will result in future compliance
problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within sixty (60) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer
27447, Raleigh, NC 27611-7447. Unless such demands are made this permit shall be final and
binding.
If you have any questions, or need additional

Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.).

depth reading and not readily penetrate into accumulated sediments.

When the permanent pool depth reads 2.25 feet in the forebay, the sediment shall be removed.

INFORMATION PERTAINING TO DEED RESTRICTIONS
AND PROTECTIVE COVENANTS
In accordance with Tide 15 NCAC 2H.1000, the Coastal Stormwater Management Regulations, deed restrictions and protective
covenants are required for High Density Commercial Subdivisions where lots will be subdivided and sold. Deed restrictions
and protective covenants are necessary to ensure that the development maintains a "built -upon' area consistent with the design
criteria used to size the stormwater control facility. The following deed restrictions and covenants must be recorded prior to the
sale of any lot:
I, EG Dale acknowledge and affirm by my signature below, that I will cause the following deed restrictions and
protective covenants to be recorded for North Brunswick Industrial Park prior to the sale of any lot:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit
Number -SW `6 021101'n0 as issued by the Division of Water Quality under NCAC 21-1.1000.
2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance
- with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties claiming under them.
4. The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State
of North Carolina, Division of Water Quality.
5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of
Water Quality.
6. The maximum allowable built -upon area per lot is as follows:
Lot # BUA Lot # BUA Lot # BUA Lot # BUA
7 106,817 ft2 1 37,575 ft2 12 55,932 ft2 6 93,273 ft2
8 37,804 ft2 2 37,230 ft2 13 37,402 ft2 10 44,621 ft2
9 100,777 ft2 3 36,975 ft2 14 30,256 ft2 11 34,156 ft2
4 36,997 ft2
Lot #5 BUA 21,622 ft2
These allotted amounts include any built -upon area constructed within the lot property boundaries, and that portion of
the right-of-way between the front lot line and the edge of the pavement. Built upon area includes, but is not limited to,
structures, asphalt, concrete, gravel, brick, stone, state, coquina and parking areas, but does not include raised, open
wood decking, or the water surface of swimming pools.
7. All nmoff from the built -upon areas on the lot must drain into the permitted system. This may be accomplished through
a variety of means including: a piped collection system, which ultimately discharges into the stormwater facility;
appropriate grading of the lot such that the built -upon surfaces drain into the stormwater facility; or graded swales which
collect runoff and direct it into the stormwater facility.
8. Built upon area is excess of the permitted amount will require a permit modification.
9. Each lot whose ownership is not retained by the permitter, is required to submit a separate stormwater permit
application to the Division of Water Quality and receive a permit prior to construction.
