Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention 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.
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 not be handled in a manner that will 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 3.75_ feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads _2.25 feet in the forebay, the sediment shall be removed.

The Wilmington Regional Office received a Stormwater Management Permit Application for
Shallotte Shops on March 29, 2004. A preliminary review of that information has determined that the
application is not complete. The following information is needed to continue the stormwater review:
1. Please either delineate all wetlands on site, disturbed or undisturbed, or note on the plans
that none exist.
2. Please provide a note on the plans that all roof drainage will be directed so as to be
picked up by the pond.
3. The off -site drainage from the Simmons property will be directed away from the pond by
a ditch. Is this ditch proposed or existing? If the ditch is proposed, please provide a
detail.
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 April 7, 2004, or the application will

Tri-Coast Properties, LLC
Mr. Jon T. Vincent, Member/Manager 313
Military Cutoff Road l�U /
Wilmington, NC 28403
Dear Mr. Vincent:
This office has received a soil erosion and sedimentation control plan for the project listed below which was
submitted as required by the North Carolina Sedimentation Pollution Control Act (NCGS 113A-57(4)).
Please be advised that this Act requires that all persons disturbing an area of one or more acres of land must
obtain approval of a soil erosion control plan prior to the commencement of said land -disturbing activity (NCGS 113A-
54(d)(4)). The Act further states that this plan must be filed a minimum of 30 days prior to the activity and the
approving authority must approve or disapprove the submitted plan within 30 days of receipt. Failure of the approving
authority to approve or disapprove the submitted plan within the 30 day period will be deemed approval of the plan
if the submitted plan is complete. Commencement or continuation of a land -disturbing activity under the jurisdiction
of this Act prior to the approval of an erosion & sediment control plan is a violation of the Act.
A copy of any erosion and sediment control plan which could involve the utilization of ditches for the purpose
of dewatering or lowering the water table is forwarded by this office to the Division of Water Quality (DWQ). It is .
suggested that you contact the Division of Water Quality at [phone] if the ditches shown on your plan will
lower the water table.
We have performed a preliminary review of your submitted plan and have determined that additional information
will be necessary before a final review can be completed. Enclosed is a checklist of items that must be submitted
before we can complete the review process. Failure to provide the additional information may result in disapproval
of your plan.
The approval of an erosion and sediment control plan is conditioned on the applicant's compliance with Federal
and State water quality laws, regulations and rules.
If you have questions or need additional information, please do not hesitate to contact this office. Your
cooperation in this matter is appreciated and we look forward to working with you on this project.
Sincerely,
