High Density Stormwater Project
Brunswick County
Dear Mr. Haywood:
The Wilmington Regional Office received a complete Stormwater Management Permit Application for J.A.Dosher
Memorial Hospital on January 30,2002. 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 980729 dated January 31,2002,for the construction ofJ.A.Dosher Memorial Hospital.
This permit shall be effective from the date of issuance until January 31,2012,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

actual impervious%and permanent pool depth. Linear grtepolatiem should be employed to determine the correct value for non-
standard table entries.
2. In the 20 coastal counties,the requirement for a vegetative filter may be waived ifthe wet detention basin is designed to provide
90%TSS removal. The NCDENR BMP manual provides design tables fec both 85%TSS removal and 90%TSS removal.
II. 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
Section: 15 A NCAC 2H.1008.
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached. If the applicant has designated an agent in the Stormwater Management Permit
Application Form,the agent may initial below. If a requirement has not been met,attach justification.
Applicants itials
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 basin volume.
c. The temporary pool controls runoff from the design storm event.
d. The temporary pool draws down in 2 to 5 days.
N/A e. If required, a 30-foot vegetative filter is provided at the outlet(include non-erosive flow
' �, calculations.
�-1�" 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-
of-way.
�,�i 1. If the basin is used for sediment and erosion control during construction,clean out of the
basin is specified prior to use as a wet detention basin.
m. A mechanism is specified which will drain the basin for maintenance or an emergency.
III. WET DETENTION 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) ❑ does El does not incorporate a vegetated filter at the outlet.
This system(check one) ❑ does ® does not incorporate pretreatment other than a forebay.
Form SWU-102 Version 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 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 5.625 feet in the main pond,the sediment shall be removed.
When the permanent pool depth reads 3.750 feet in the forebay,the sediment shall be removed.

plants shall be encouraged to grow along the vegetated shelf and forebay berm.
6. If the basin must be drained for an emergency or to perform maintenance,the flushing of sediment through

NARRATIVE
STORMWATER MANAGEMENT MEASURES:
The project site is located in the City of Southport in Brunswick County. Land disturbing
on the site will exceed one acre which requires the site to comply with the State Regulations. The
stormwater runoff from the development will be directed to the existing stormwater detention
pond. The stormwater detention pond was designed to accommodate this site at 70% impervious
area lot coverage. The existing pond will be modified to treat the additional runoff per State
requirements. The existing pond was permitted under number SW8 980729 on
December 22, 1998.
