Stormwater Management Permit SW7100602
Maple Commerce Park
Currituck County
Dear Mr. Stikeleather:
WOF-D
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7100602 for a stormwater treatment system consisting of a wet
detention pond serving the Maple Commerce Park in Currituck County expires on
December 31, 2021. This is a reminder that permit renewal applications are due 180
days prior to expiration. We do not have a record of receiving a renewal application.
Please submit a completed permit renewal application along with a $505.00 fee for
permit renewal. Application forms for renewal can be found on our website at:
httpr://deq nc gov/about/divisions/energy-mineral-land-resources/energy-mineral-land-
rules/stormwater-program/12ost-construction. North Carolina General Statutes and the
Coastal Stormwater rules require that this property be covered under a stormwater
permit. Failure to maintain a permit subjects the owner to assessment of civil penalties.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application form. You can request a copy by e-mailing me at roger.thorpe(aDncdenr.gov.

RE: Cafferty Enterprises Service Facility
Lot 1, Maple Commerce Park, Currituck County
Stormwater Permit SW7100602 Minor Modification
Dear Mr. Dumpor:
Please find the enclosed submittal for the Minor Modification of the Stormwater Management
Permit for the Maple Commerce Park (SW7100602) for the Cafferty Enterprises Service Facility.
The modification pertains to Lot 1 of the Commerce Park for a 12,245 sf service building to serve
Outer Banks Blue with their operations. Cafferty Enterprises, LLC is under agreement with the
County to purchase the 6.0 acre lot. The anticipated disturbance will be approximately 1.9 acres,
as much of the lot will remain undisturbed. The enclosed submittal includes the following items:
Stormwater Management Minor Modification Application
Plan Sheets (2 sets)
o C101 — Demo & Erosion Control Plan (dated 12/22/2017)
o C201 - Site Plan (dated 12/2212017)
o C202 — Site Plan Details (dated 12/22/2017)
o C301 — Grading & Drainage Plan (dated 12/22/2017)
Please note that the proposed coverage of 30,682.4 sf remain well below the allowable limits of
170,000 sf documented in the permit and that all runoff is directed into the Commerce Park
collection system where it is conveyed to the permitted pond. The remainder of the 170,000 sf
allowable coverage shall be kept in reserve for this lot for future development potential. Work on
this is expected to begin this winter with completion / facility start up in June of 2018. 1 appreciate
your cooperation with this permit modification. Please call me if you have any questions.

Kim,
I've finally been able to discuss this request with both Al and Bill. We are willing to cover the construction of the
temporary access drive in with the future permit for the WWTP without requiring the Commerce Park wet pond to be
constructed. We are all in agreement to allow the county to construct a temporary narrow access drive from the Coop
Ext. office complex up and around to the entrance to the WWTP site as proposed in your email. We would like the drive
to be as narrow as possible, and if there is no dire need for roadside collection swales, then please do not include them,
sheet flow is always better. The stormwater application form should include this road area in a separate Drainage Area
column and the plans for the WWTP should include the temporary drive area & details with discussion in the narrative
with a note on the plans that the road will not be improved to the original Commerce Park design (24' wide) until the
Commerce Park pond is constructed and ready. If you or the county have any questions please call or write. Thanks,
Scott

Subject: Maple Commerce Park and Sewage Treatement Plant
Scott,
Attached is a pdf that shows the portion of roadway within the Maple Commerce Park that we would need to construct
to provide access to the adjacent Sewage Treatment Plant. We would plan to fully construct only the portion that is
curb and gutter and designed to flow to the existing pond at the Cooperative Extension Office. (And yes, I've just realized
this affects the YMCA and the package that is already on its way to you — I don't think the affect is drastic, but it may
require some minor changes in the talcs). The remaining portion of the road will most likely be constructed of gravel
only and temporary roadside ditches will drain to an existing ditch between the Commerce Park and the treatment
plant.
The treatment plant should be low density. The only coverage will be for the access, the building, a small parking lot and
some narrow drives for access to the underground tanks. The treated wastewater that will be discharge from the plant
will be sprayed over sand filled high rate infiltration ponds. The ponds will be surrounded by a dewatering system that
will pump ground water to an open pond. Please advise me if there are any special permitting steps with DWQ for this
process.
Thank you for your assistance with this project.

Important maintenance procedures:
JUN - 2 2010
D11P'?-WA,R0
— 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.

Deed Restrictions & Protective Convenances
` W-WAR0
In accordance with Title 15 NCAC 2H.1000 and S.L. 2006-246, the 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, Eric T. Weatherly, P.E., Currituck County Engineer , acknowledge, affirm and agree by my
signature below, that I will cause the following deed restrictions and covenants to be recorded prior to
the sale of any lot within the project known as Maple Commerce Park
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number , as issued by the Division of Water Quality
under the Stormwater Management Regulations.
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 65% of the lot area
The maximum built -upon area per lot, in square feet, is as listed below:

High Density Commercial Subdivisions
Deed Restrictions & Protective Convenances
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.
9. The project and each lot will maintain a 50** foot wide vegetated buffer between all impervious
areas and surface waters.
