Alan W. Klimek, P.E. Director
Division of Water Quality
The Wilmington Regional Office received a complete Stormwater Management Permit Application for
Lake Brewster Subdivision on November 19, 2004. 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. We are forwarding Permit No. SW8 041111 dated November 24, 2004, for the
construction of the project, Lake B.
This permit shall be effective from the date of issuance until. November 24, 2014, 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 thirty (30) 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.

parking areas, but does not include raised, open wood decking, or the

drain into the system are not required to provide these measures.
h. Built -upon area in excess of the permitted amount will require a permit
modification.

tubing, may be used only if they draw water from the surface in the deepest
part of the pond.
C. The failing water from the fountain must be centered in the pond, away from
the shoreline.

permanent pool volume. The maximum pump power for a fountain in this
pond is 3/4 horsepower.

the transfer. Records of maintenance activities performed to date will be
required.

necessary to assure that all components of the permitted stormwater system
function at optimum efficiency. The approved Operation and Maintenance Plan

"Name/Ownership Change Form" must be submitted to the Division of Water
Quality accompanied by appropriate documentation from the parties involved.
This may include, but is not limited to, a deed of trust, recorded deed restrictions,
Designer's Certification and a signed Operation and Maintenance plan. The
project must be in good standing with DWQ. The approval of this request will be
considered on its merits and may or may not be approved.
2. The permittee is responsible for compliance with all of the terms and conditions
of this permit until such time as the Director approves the transfer request.
3. Failure to abide by the conditions and limitations contained in this permit may
subject the Permittee to enforcement action by the Division of Water Quality, in
accordance with North Carolina General Statute 143-215.6A to 143-215.6C.

1. PROJECT INFORMATION
Project Name: Lake Brewster
Contact Person: Amie Drucker, P.E. _ Phone Number: 843 280-5870
For projects with multiple basins, specify which basin this worksheet applies to:
elevations
Basin Bottom Elevation 0.0 ft. (floor of the basin)
Permanent Pool Elevation 6.0 ft. (elevation of the orifice)
Temporary Pool Elevation 6.7 ft. (elevation of the discharge structure overflow)
areav
Permanent Pool Surface Area 92,075 sq. ft. (water surface area at the orifice elevation)
Drainage Area 36.06 ac. (on -site and off -site drainage to the basin)
Impervious Area 17.63 ac. (on -site and off -site drainage to the basin)
volumes
Permanent Pool Volume 176,715 Cu. ft. (combined volume of main basin and forebay)
Temporary Pool Volume 65,907 cu. ft. (volume detained above the permanent pool)
Forebay Volume 39,750 cu. ft. (approximately 20% of'total volume)

Footnotes:
When using the Division SAIDA tables, the correct SAIDA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
Z In the 20 coastal counties, the requirement for a vegetative filter may be waived it' the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.

Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
. a:, ` Inspect the wef detention basin system for sediment acdumulation, 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 necessaryto maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3.' 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.).
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.
When the permanent pool depth reads i 7.5 feet in the main pond; the, sediment shall be removed.
When the permanent pool depth reads 3 fe6fin the forebay, the sediment shall be removed.
