Shipyard Commons Business Park
High Density Subdivision Stormwater Project
New Hanover County
The Wilmington Regional Office received a request to modify the Stormwater Management Permit Application for
Shipyard Commons Business Park due to an ownership change, on April 27, 2000. 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 000120, dated May 17, 2000, to you for the
construction of the project, Shipyard Commons Business Park.
This permit shall be effective from the date of issuance until May 17, 2010, 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.
If you have any questions, or need additional information concerning this matter, please contact Linda Lewis, or me
at [phone].
Sincerely,
Rick Shiver

6. The stormwater management system shall be constructed in it's entirety, vegetated and operational for its
intended use prior to the construction of any built -upon surface.
7. During construction, erosion shall be kept to a minimum and any eroded areas of the system will be repaired
immediately.
8. Upon completion of construction, prior to issuance of a Certificate of Occupancy, and prior to operation of
this permitted facility, a certification must be received from an appropriate designer for the system installed
certifying that the permitted facility has been installed in accordance with this permit, the approved plans
and specifications, and other supporting documentation. Any deviations from the approved plans and
specifications must be noted on the Certification.

Footnotes:
When using the Division SAIDA tables, the correct SAIDA ratio for permanent pool sizing should be computed based upon the
actual impervious Flo 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 NCDENR BMP manual provides desibn tables for both 85% TSS removal and 9051r, TSS removal.

calculations)
The basin length to width ratio is greater than.3:1.

The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the
vegetated filter if one is provided.
This system (check one) 0 does Vdo not incorporate a vegetated filter at the outlet.
This system (check one) 0 does ees not incorporate pretreatment other than a forebay.
Form SWU-102 Rev 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
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
(Le. 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-pawl depth reads F. G feet in the main -pond the sediment shall be removed.
When the permanent pool depth reads t7,(Q feet in the forebay, the. sediment shall be removed.

Re: Shipyard Commons Business Park, SW8 000120
Dear Linda:
Attached please find a new application and signed supplement for the above
project. As per our phone conversation today, the only change is the legal name of
the corporation. I mistakenly submitted the original application in the wrong
corporate name.
As always, if you have any questions or comments, please feel free to call me.
Thanks for your understanding in this matter.
Sincerely,
David S. Hollis, PE, PLS
