Subject: Stormwater Permit No. SW8 010903 Modification
The Palms at Dunhill
High Density Project
New Hanover County
Dear Mr. Simpson:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for The Palms at Dunhill on June 16, 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 21-11.1000. We are forwarding
Permit No. SW8 010903 dated June 22, 2004, for the construction of the subject
project.
This permit shall be effective from the date of issuance until June 22, 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.
The original plans dated August 9, 2001 and last revised on November 5, 2001 along
with the current plans dated August 29, 2003 and last revised on June 15, 2004 are
incorporated into this permit by reference. The existing 65 room hotel site will remain
unchanged except for the addition of the driveway to the south.
The following changes were made to this permit:
1. The facility name was changed to The Palms at Dunhill versus Amerihost Inn &
Suites.
2. The mailing address of the owner changed to 419 Marina Street, Carolina
Beach, NC 28428 versus 5202 Carolina Beach Road, Suite 16, Wilmington,
NC 28412.
3. Total impervious surface area increased to 76,831 square feet versus 68,255
square feet.
4. The wet detention pond was redesigned to provide additional surface area and
volume. The following changes were made:

5. Section 11, condition 1 on page 5 of the permit will need to be addressed in
order to bring the facility back into compliance. As discussed in a Notice of
Inspection dated March 4, 2004 that this office sent to your facility, the slopes of
the existing pond are eroding and they are not grassed with permanent
vegetation. This deficiency must be corrected and the system brought back
into compliance prior to the construction of any additional built -upon surface.
Section II, Condition 1 reads as follows:
Upon completion of the modifications to the existing stormwater
management system, which include regrading the slopes of the wet
detention pond to increase its surface area and volume, the
stormwater management system shall be vegetated including the
establishment of wetland plants on the vegetated shelf, and
operational for its intended use prior to the construction of any
additional built -upon surface.
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 27$11-
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 Rhonda Hall, or me at [phone].
Sincerely,
Rick Shiver
Water Quality Regional Supervisor

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 tablc 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 BW manual provides design tables for both 85% TSS removal and 90% TSS removal.
11. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code

Maintenance activities shalt/ be performed as follows:
. After every significant ntnoff 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 with]11
2 to 5 days as designed.
2. Repair eroded areas immediately, rc-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 frotn 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 3.0 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.
