11. SCHEDULE OF COMPLIANCE
No homeowner/lot owner/developer shall fill in, alter, or pipe any drainage feature (such as
swales) shown on the approved plans as part of the stormwater management system without
submitting a revision to the permit and receiving approval from the Division.
The permittee is responsible for verifying that the proposed built -upon area for the entire lot,
including driveways and sidewalks, does not exceed the allowable built -upon area. Once the lot
transfer is complete, the built -upon area may not be revised without approval from the Division
of Water Quality, and responsibility for meeting the built -upon area limit is transferred to the
individual property owner.
If an Architectural Review Board or Committee is required to review plans for compliance with
the BUA limit, the plans reviewed must include all proposed built -upon area. Any approvals
given by the Board do not relieve the homeowner of the responsibility to maintain compliance
with the permitted BUA limit.
The permittee shall submit to the Director and shall have received approval for revised plans,
specifications, and calculations prior to construction, for any modification to the approved plans,
including, but not limited to:
a. Any revision to the approved plans, regardless of size.
b. Project name change.
C. Transfer of ownership.
d. Redesign or addition to the approved amount of built -upon area.
e. Further subdivision, acquisition, or sale of all or part of the project area. The project area
is defined as all property owned by the permittee, for which Sedimentation and Erosion
Control Plan approval or a CAMA Major permit was sought.
f. Filling in, altering, or piping of any vegetative conveyance shown on the approved plan.
The Director may determine that other revisions to the project should require a modification to
the permit.
6. The Director may notify the permittee when the permitted site does not meet one or more of the
minimum requirements of the permit. Within the time frame specified in the notice, the permittee
shall submit a written time schedule to the Director for modifying the site to meet minimum
requirements. The permittee shall provide copies of revised plans and certification in writing to
the Director that the changes have been made.

The stormwater management system shall be constructed in its entirety, vegetated and
operational for its intended use prior to the construction of any built -upon surface.
8. During construction, erosion shall be kept to a minimum and any eroded areas of the system will
be repaired immediately.
9. 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.
10. If the stormwater system was used as an Erosion Control device, it must be restored to design
condition prior to operation as a stormwater treatment device, and prior to occupancy of the
facility.
11. Permanent seeding requirements for the stormwater control must follow the guidelines
established in the North Carolina Erosion and Sediment Control Planning and Design Manual,
12. Prior to the sale of any lot, the following deed restrictions must be recorded:
a. The following covenants are intended to ensure ongoing compliance with State
Storm%vater Management Permit Number S W6091002, as issued by the Division of
Water Quality under NCAC 2H .1000.
b. The State of North Carolina is made a beneficiary of these covenants to the extent
necessary to maintain compliance with the Stormxvater Management Permit.
C. These covenants are to run with the land and be binding on all persons and parties
claiming under them.
d. 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.
C. Alteration of the drainage as shown on the approved plans may not take place without the
concurrence of the Division of Water Quality.

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 swinuning pools.
g. All runoff on the lot must drain into the permitted system. This may be accomplished
through providing roof drain gutters, which drain to the street, grading the lot to drain
toward the street, or grading perimeter swales and directing them into the pond or street.
Lots that will naturally drain into the system are not required to provide these measures.
i. Built -upon area in excess of the permitted amount will require a permit modification.

High Density Residential Subdivisions
Deed Restrictions &Protective Covenances
In accordance with Title 15 NCAC 2H.1000 and S.L. 2006-246, the Stormwater Management Regulations,
deed restrictions and protective covenants are required for High Density Residential 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, Donnie Douglas , 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 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 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
See Exhibit A-1
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.
8. 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.

Wet Detention Basin Operation 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
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 0 does not incorporate a vegetated filter at the outlet.
This system (check orte):
❑ does D 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.
