Jerry Porter Auto Dealership
High Density Stormwater Project
New Hanover County
The Wilmington Regional Office received a complete modification to the Stormwater Management Permit
Application for Jerry Porter Auto Dealership on November 30, 1999. Staff review of the plans and specifications
has deteralined 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 940120 Modification dated December 1, 1999, for the
construction of Jerry Porter Auto Dealership.
This permit shall be effective from the date of issuance until December 1, 2009, and shall be subject to the conditions
and limitations as specified therein. Please pay special attention to the Operation and Maintenance requirements in
this perm�t. Faure 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 thiso,�errmt are unacceptable, you have the right to request an
adjudicatory hearing upon written request within thirty (3 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

TE 99059
The total drainage area of this project is 4.16 acres. Two existing buildings totaling 8,092
sf will remain. An asphalt access and parking area for both buildings will total 49,781 sf.
94,360 sf of asphalt access and parking area are already permitted. A complete 152,598
sf of impervious area (365 sf of sidewalk) brings the total built upon area to 84.2%
impervious.
Stormwater runoff will be handled by a wet detention pond designed to exceed the states
requirement of the first one inch of runoff. This pond will drain to Smith Creek with a
classification of C-SW. A vegetated filter is not required due to the 90% TSS removal
used in the wet detention design.

a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
b. The forebay volume is approximately equal to 20% of the total basin volume.
c. The temporary pool controls runoff from the design storm event.
d. The temporary pool draws down in 2 to 5 days.
e. If required, a 30-foot vegetative filter is provided at the outlet (include non -erosive flow
calculations),
f. The basin length to width ratio is greater than 3: 1.
g. The basin side slopes above the permanent pool are no steeper than 3: 1.
h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
i. Vegetative cover above the permanent pool elevation is specified.
j. A trash rack or similar device is provided for both the overflow and orifice.
k. A recorded drainage easement is provided for each basin including access to nearest right-
K of -way.
1. If the basin is used for sediment and erosion control during construction, clean out of the
basin is specified to be performed prior to use as a wet detention basin
m. A mechanism is specified which will drain the basin for maintenance of an entergency.
Ull. WETDETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
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 X does not incorporate a vegetated filter at the outlet.
This system (check one) 0 does X does not incorporate pretreatment other than a forebay.
ForniSWIJ-102 Rev3.99 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 system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition. I
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 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 4.875 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.

through the emergency drain shall be minimized to the maximum extent possible.
