�uvrd 0Y\ -Ci Vet'
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for Ocean Gate Plaza at Westgate on November 22, 2005. 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 051112 dated December 15, 2005, for the construction of
the subject project.
This permit shall be effective from the date of issuance until December 15, 2015, 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 fled

Footnotes:
When using the Division SA/DA tables, the correct SA/DA 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.
In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The P:CDENR BMP manual provides design taoles for both 85% TSS removal and 90% TSS removal.
II. REQUIRED ITEMS CHECKLIST

This system (check one) 0 does Kdoes not incorporate pretreatment other than a forebay.
Form SWU-102 Rev 3.99 Page 2 of 4

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.
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 `% 5 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads ' -5 feet in the forebay, the sediment shall be removed.

that the volume was the total, main plus foreba y . ! also had to modify the
values and line work on the drawings because of the 10' shelf area.
2. 1 labeled the permit numbers on the cover sheet as requested, including the
Wal-Mart number.
3. Modified the drawings on sheets 2 and 3 to reflect a 10' vegetated shelf.
As always, if you have any questions or comments, please feel free to call me.

Dear Ms. Alexander:
The Wilmington Regional Office received a Stormwater Management Permit Application for
Ocean Gate Plaza at Westgate on November 7, 2005. A preliminary review of that information
has determined that the application is not complete. The following information is needed to
continue the stormwater review:
,P0-Yk}- 1.:,, lease clarify the stage -storage table column headings for the pane °Rpinuu
t�yv(6 y VWSEL". It appears from the calculations that the 4th and 5th columns ("Incr. Vol.
and Incr. Storage) are combined totals of the main basin and forebay, and the
35,781 cu ft total labeled "Main Pond Volume" is the total basin volume (main
plus forebay).
2. Tease label the previously approved permits (SW8 numbers) on Sheet 1 at each
a I ble area. Numbers that I am aware of are: (a) SW8W403, Ocean Gate
Su ivl ' n Pond #1; (b) SW.09'K807, West Gate, and associated offsite permit
S 07, Cross Creek �ofessional Plaza; and 1c1 SW8 40703, Hunterstone
Apart ents. OfD�fCv
3. lease provide the pond with a 10 ft wide minimum vegetated shelf at a 6:1 slope
"IN / Kor flatter, as required by 15A NCAC 2H.1008(e)(9), and recommended by
0-7,$h Section 1.3 of the April 1999 BMP Manual.
Please note that this request for additional information is in response to a preliminary review.
The requested information should be received by this Office prior to December 1, 2005, or the
application will be returned as incomplete. The return of a project will necessitate resubmittal of
all required items, including the application fee.
if you need additionai time to submit the information, please mail or fax your request for a time
extension to the Division at the address and fax number at the bottom of this letter. The
request must indicate the date by which you expect to submit the required information.

RE: Ocean Gate Plaza at Westgate, proposed pond site g,__�r:
Dear Mr. Farrell:
This correspondence is in reference to the project referred to herein as the Ocean Gate Plaza at
Westgate, located off of Westgate Drive, Leland, Brunswick County, North Carolina. Our client
is proposing a stormwater pond to handle runoff from proposed development in the area.
In order for our client to secure state permits for sedimentation and erosion control, as well as
stormwater, we are requesting your review of this set of plans and profiles which include a
preliminary delineation which we are in the process of completing on the balance of the site. We
will be requesting a jurisdictional determination on the remainder of the wetland delineation in
the future. However, we only require that you review our preliminary determination at this time.
If you have any questions or need additional information, please call me at 910.452.2711.

WATER QUALITY CONSIDERATIONS -
Impervious area calculations: See Project Data Sheet
TOTAL IMPERVIOUS = 1.6 acres
TOTAL AREA DRAINING TO POND = 5.0 acres
5.0 acres total —1.6 acres impervious = 3.4 acre green area
SA REQUIRED: 1.6 / 5.0 = 0.32, or 32%
At 6' depth, 90% TSS removal, from chart — SA/DA factor = 1.7
5.0 x 0.01 x 1.7 = 3,700 sf SA REQUIRED
