Dear Mr. Bayer:
On May 30, 2014 a compliance inspection was conducted for the tract/project known as
Patriot Park, located at 404 Miller Boulevard in Havelock, NC. State Stormwater permit
SW71 11108 was issued for the construction and operation of a wet detention pond that will treat
stormwater runoff from impervious surfaces on site for the life of the project. A file review noted
that we have not received a designer's certification for this project. Condition number 11. 10, states
Upon completion of construction, prior to issuance of a certificate of occupancy, and prior to
operation of this permitted facility, a certification must be received from an appropriate designer for
the system installed certifying that the permitted facility has been installed in accordance with this
permit, the approved plans and specifications, and other supporting documentation. Any deviations
from the approved plans and specifications must be noted on the Certification. A modification may
be required for those deviations."
Please be advised that you are required to comply with the terms, conditions and limitations of your
Stormwater Management Permit under Title ISA North Carolina Administrative Code 2H .1003
and North Carolina General Statute 143-214.7. Failure to comply with the terms of your permit may

Subject: Stormwater Permit Renewal & Ownership Change
Stormwater Management Permit SW7111108
Patriot Park
Craven County
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7111108 for a stormwater treatment system consisting of a wet
detention pond serving Patriot Park located at 404 Miller Boulevard in Havelock, NC
expires on February 2, 2020. 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.
The permit was originally issued to Satwear, LLC. It was noted in the Craven County tax
records that the wet pond property is now owned by Patriot Park POA, Inc. Permits are
not automatically transferred to new owners without the submittal of an ownership
change application and fee. Please submit a completed permit renewal application
along with a $505.00 fee for permit renewal and an ownership change application with
an additional $505.00 fee. Application forms for renewal and ownership change can be
found on our website at:
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 (252) 948-3923. 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

Dear Mr. Bayer:
This office received a Coastal Stormwater permit application and plans for the modification of the subject project
on November 18, 2011 with additional information received on November 28, 2011. A preliminary review of the project
indicates that before a State Stormwater permit can be issued the following additional information is needed.
The outlet structure detail found on plan sheet 12 of 13 has the upturned elbow elevation (ic. Permanent Pool
Elevation) given as 19,00 whereas it should be 18,00fms1. Please revise.
Please revise the Orifice Drawdown calculations to use the minimum design (1.50") volume of 9,622ef when
determining the size of the drawdown orifice instead of the provided volume of 20,415cf in order to keep the
discharge of just the design storm event between 2 to 5 days. Please revise & submit the drawdown calculations,
page 2 of Wet Detention Basin Supplement form, and the outlet structure detail on plan sheet 12,
Please do not forget to have any plans, calculations, supplements, narrative, etc. revised, signed, sealed and dated
as necessary to reflect all changes when re -submitting.
The above requested information must be received in this office prior to February 13, 2012 or your application
will be returned as incomplete. The return of this project will necessitate resubmittal of all required items including the
application fee. If you need additional time to submit the required information, please mail or fax your request for
time extension to this office at the Letterhead address.
You should also be aware that the Stormwater Rules require that the permit be issued prior to any development
activity. Construction without a permit is a violation of 15A NCAC 21-1_ 1000 and North Carolina. General Statute 143-
215.1 and may result in civil penalties of up to $10,000 per day.
Please reference the Stormwater Project Number above on all correspondence. If you have questions, please feel

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a t/, , yo
log in a known set location. Any deficient BMP elements noted in the inspection will be �G"IT
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,

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.

Deed Restrictions & Protective Covenances
In accordance with Title 15 NCAC 2H.9000 and S.L. 2006-246, the Stormwater Managem e s���
deed restrictions and protective covenants are required for High Density Residential Sub i i ed
lots will be subdivided and sold and runoff will be treated in an engineered Stormwater cunt f ci V.
e
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, Lawrence J. Bayer Jr. 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:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number S W 7 ) I It GJ? 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 4,000 square feet. 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.
OR, if the proposed built -upon areas per lot will vary, please REPLACE #6 above with the following:
6. The maximum built -upon area per lot, in square feet, is as listed below:
Lot # BUA Lot # BUA Lot # BUA Lot # BUA
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. Each lot will maintain a 30** foot wide vegetated buffer between all impervious areas and surface
waters.
**50 foot for projects located in the 20 coastal counties.
& 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.
