Hermitage Park Warehouse
High Density Stormwater Project
Dear Mr. Sneeden: Brunswick County
The Wilmington Regional Office received a complete Stormwater Management Permit Application for Hermitage
Park Warehouse on November 14. 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 000824 dated December 14,2000,for the construction of Hermitage Park Warehouse.
This permit shall be effective from the date of issuance until December 14, 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 2761 1-7447. Unless such demands
are made this permit shall be final and binding.

Footnotes:
I. When using the Division SA/DA tables,the correct SA/DA 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 table entries.
2. 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 design tables for 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 Initials
611X1 a. The permanent pool depth is between 3 and 6 feet(required minimum of 3 feet).
(�52L 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.
Cow 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.
C121 g. The basin side slopes above the permanent pool are no steeper than 3:1.
rj:;e, It. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
CVc- i. Vegetative cover above the permanent pool elevation is specified.
CCC, j. A trash rack or similar device is provided for both the overflow and orifice.
CCL k. A recorded drainage easement is provided for each basin including access to nearest right-
of-way.
Clx 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
CpL in. 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 oes not incorporate a vegetated filter at the outlet.
This system (check one) 0 does �does not incorporate pretreatment other than a forebay.
Forin SWU-102 Rev 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 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. Jnspect 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 4.5 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.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
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 the emergency drain shall be minimized to the maximum extent possible.
Form SWU-102 Rev 3.99 Page 3 of 4

7. All components of the wet detention basin system shall be maintained in good working order.

The Hermitage Park Warehouse project is an existing site totaling 13.7 acres. 4.0 acres of
the site is proposed to be developed at this time. Within the 4.0 acres, there is a proposed
30,000 sf building, an existing 9,980 sf building, and 25,650 sf of existing gravel parking
area.
The 4.0 acres will be treated by wet detention. The site drains to an unknown tributary of
Prince George Creek with a classification of C-SW. The pond is designed to exceed the
State's I" requirement.

Subject: ACKNOWLEDGMENT OF RECEIPT AND
REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 000824
Hermitage Park Warehouse
Brunswick County
Dear Mr. Sneeden:
The Wilmington Regional Office received a Stormwater Management Permit Application for
Hermitage Park Warehouse on August 15, 2000. A preliminary review of that information has determined
that the application is not complete. The following information is needed to continue the stormwater
review:
I. Delineate all wetlands on site, disturbed or undisturbed, or note on the plans that none exist.
2. Is CP&L aware that a detention pond is proposed within their right-of-way? Please provide
documentation from CP&L acknowledging and approving the pond's location.
I Please specifi, pond shelf vegetation.
4. Does the access road from Blue Clay Road have a name or a number? How will I know
which road to turn down to find the project?
5. Please provide existing spot elevations and dimensions for the existing gravel area and drive.
6. A portion of the existing gravel will be taken over by the new building, but no replacement
gravel has been specified. Please confirm that no new gravel areas are proposed.
7. Please delineate the 4 acre project/drainage area.
S. Please dimension the existing building.
9. It appears that the site's elevation increases toward the northwest. It appears that there is the
potential for offsite runoff to enter this pond. Please provide sufficient existing and
proposed grading, and existing or proposed drainage features to support your conclusion.
10. The proposed building is labeled as 200' x 50'. I believe this should be 200' x 150'.
