TRACY DAVIS
Director
The Wilmington Regional Office received a complete, Stormwater Management Permit Application for
Hampstead Marine Center on April 25, 2017. 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 and Session Law 2008-211. We are forwarding Permit No. SW8 170208 dated April 27, 2017,
for the construction, operation and maintenance of the BMP's and built -upon areas associated with the
subject project.
This permit shall be effective from the date of issuance until April 27, 2025, and shall be subject to the
conditions and limitations as specified therein. Please pay special attention to the conditions listed in this
permit regarding the Operation and Maintenance of the BMP(s), recordation of deed restrictions,
certification of the BMP's, procedures for changing ownership, transferring the permit, and renewing the
permit. Failure to establish an adequate system for operation and maintenance of the stormwater
management system, to record deed restrictions, to certify the BMP's, to transfer the permit, or to renew
the permit, 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 by filing a written petition with the Office of Administrative Hearings
(OAH). The written petition must conform to Chapter 150B of the North Carolina General Statutes, and

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.
2. This stormwater system has been approved for the management of stormwater runoff
as described in Section 1.6 of this permit. The runoff from all built -upon area within the
permitted drainage area of this project must be directed into the permitted stormwater
control measure. The stormwater control measure has been designed to handle the
runoff from a total pf 149,599 square feet of impervious area which includes 119,599 sf
currently proposed and 30,000 sf for future development.
3. The overall tract and the drainage area will be limited to the amount of built -upon area
indicated in Sections 1.2 and 1.6 of this permit, and per approved plans.
4. A 50' wide vegetative buffer must be provided and maintained adjacent surface
waters, measured horizontally from and perpendicular to the normal pool of
impounded structures, the top of bank of both sides of streams and rivers and the
mean high water line of tidal waters.
5. All runoff being directed into wetlands shall flow into and through those wetlands at a
non -erosive velocity.

Control device, it must be restored to design condition prior to operation as a
stormwater treatment device, and prior to occupancy of the facility.
4. The permittee shall at all times provide the operation and maintenance necessary to
assure that all components of the permitted stormwater system function at design
condition. The approved Operation and Maintenance Agreement is incorporated by
reference into this permit and must be followed in its entirety and maintenance must

fountain will be allowed in the stormwater treatment system, subject to the following
criteria:
a. The fountain must draw its water from less than 2' below the permanent pool
surface.

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
Stormwater Runoff from the drainage area will be collected by means of invereted crown drop inlets and
storm sewer. The run-off will be treated in a wet detention basin. After treatment the pond outflows to the
on site wetlands which drain into an unnamed tributairy that flows into Mullet Run 18-87-9-1
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUD Approval Date:
❑ Valid Building Permit Issued Date:

between the banks of streams and rivers, the area below the Normal Hi h Water (NHvvJ line or Mean High Water
(MHW) line, and coastal wetlands landward from the NHW (or Za line. The resultant project area is used to
calculate overall percent built upon area (B A). Non -coastal wetlands landward of the NHW (or MHK9 line may
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 43.6 %

Wet Detention Basin Operation and Maintenance Agreement
I will keep a tenance record on this B1i+lI'. This maintenance record will be kept in a
log in a known set location. Any deficient BUF elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
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 operation and maintenance should be kept in a known set
location and must be available upon request
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
