Dear Mr. Brydge:
The Washington Regional Office received a complete Stormwater Management Permit Application
for Norandex Reynolds, located at 435 Garner Road, on December 10, 2007. 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.
SW7071121 dated December 11, 2007, for the construction of the subject project.
This permit shall be effective from the date of issuance until December 11, 2017, 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 and in the submitted application. 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

I. DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data.
This stormwater system has been approved for the management of stormwater runoff as
described in Section 1.6 on page 3 of this permit. The stormwater controls have been
designed to handle the runoff from 49,207 square feet of impervious area.
All stormwater collection and treatment systems must be located in either dedicated
common areas or recorded easements. The final plats for the project will be recorded
showing all such required easements, in accordance with the approved plans and permit.
4. The tract will be limited to the amount of built -upon area indicated on page 3 of this
permit, and per approved plans.
5. Approved plans and specifications for this project are incorporated by reference and are

1. In the space provided below, summarize how stormwater will be treated. Also attach a detailed narra
(one to two pages) describing stormwater management for the project.
This project includes 2.27 acres for construction of a slab on grade metal building. Stormwater management will
be provided by a wet detention pond. ADDroximately 49% of the site and 67% of the drainage divide is
impervious. Run off from all impervious surfaces will drain to a wet detention pond. Prior to entering the main
pool, run-off will drain t a forebay. The pond outfalls to an exisitng swale and into and an exisitng junction box
and existing Swale along Garner Road. The 4' concret riser and 1.25" draw down orifice will draw down the
desing storm in 81 hours or 3.3 days
2. Stormwater runoff from this project drains to the Neuse River basin.
3. Total Site Area: 2.27 acres 4. Total Wetlands Area: 0 acres
5. 100' Wide Strip of Wetland Area: acres (not applicable if no wetlands exist on site)
6. Total Project Area**:2.27 acres 7. Project Built Upon Area:49 %

Wet Detention Basin Inspection and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity

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 ® does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
- Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
- No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
- Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.

- If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
- Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of inspection and maintenance should be kept in a known set
location and must be available upon request.

In accordance with Title 15 NCAC 2H.1000, the Coastal Stormwater Management Regulations, deed
restrictions and protective covenants are required for High Density Commercial Subdivisions where lots will
be subdivided and sold and runoff will be treated in an engineered stormwater control facility. Deed restrictions
and protective covenants are necessary to ensure that the development maintains a built -upon area consistent
with the design criteria used to size the stormwater control facility.
I, R. Mitchell Brydge
deed restrictions an(
affirm and agree by my signature below, that I will cause the following
e recorded prior to the sale of any lot within the project known as
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number S W `l cQ I i a as issued by the Division of Water Quality under
NCAC 2H.1000.
2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to
maintain compliance with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties claiming under
them.
4. The covenants pertaining to stormwater may not be altered or rescinded without the express written
consent of the State of North Carolina, Division of Water Quality.
5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of
the Division of Water Quality.
6. The maximum allowable built -upon area per lot is square feet. {OR, if the proposed built -
upon area per lot will vary, please use the following format & language (in bold):
The maximum built -upon area per lot, in square feet, is as listed below:
Lot # BUA Lot # BUA Lot # BUA Lot # BUA
1_ 49207 2
This allotted amount includes any built -upon area constructed within the lot property boundaries, and
that portion of the right-of-way between the front lot line and the edge of the pavement. Built upon area
includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and
parking areas, but does not include raised, open wood decking, or the water surface of swimming
pools.
7. All runoff from the built -upon areas on the lot must drain into the permitted system. This may be
accomplished through a variety of means including roof drain gutters which drain to the street, grading
the lot to drain toward the street, or grading perimeter swales to collect the lot runoff and directing them
into a component of the stormwater collection system. Lots that will naturally drain into the system are
not required to provide these additional measures.
8. The owner of each lot, whose ownership is not retained by the permittee, is required to submit a separate
stormwater permit application to the Division of Water Quality and receive a permit prior to
construction.
