the express written consent of the State of North Carolina, Division of Water
Quality.
e. Alteration of the drainage as shown on the approved plans may not take place

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. -
Lots within CAMA's Area of Environmental Concern may be subject to a reduction
in their allowable built -upon area due to CAMA regulations.
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.
17. A copy of the recorded deed restrictions must be submitted to the Division within 30 days

or the water surface of swimming pools.
19. 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.

High Density Residential Subdivisions
Deed Restrictions & Protective Covenances
In accordance with Title 15 NCAC 2H.1000, the Stormwater Management Regulations, deed restrictions and
tective covenants are required for High Density Residential Subdivisions where lots will be subdivided and
I and runoff will be treated in an engineered stormwater control facility. Deed restrictions and protective
enants 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, � �c/e-i/ 72, acknowledge, affirm and agree by my signature below, that I will
cause -the following ded resetriction? 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 SGj9 o86 y.z2_ , 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. 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 (ee/ri9iT /�
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.
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 co on v��of the stormwater collection system. Lots that will naturally drain into the system are
not requi ed to prow e hese additional measures.

Infiltration 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.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter 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 will be kept in a known set location
and will be available upon request.
® Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Infiltration 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.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter 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 will be kept in a known set location
and will be available upon request.
® Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
