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, Mike Shea , 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 The covenants pertaining to stormwater may not be altered or rescinded without the express written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 4100 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.
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.

BMP OPERATIONS AND MAINTENANCE PLAN
THE FOLLOWING ITEMS SHALL BE INSPECTED/MAINTAINED BY THE OWNER.
A VEGETATION
1. GOOD GRASS COVER SHALL BE MAINTAINED AROUND THE POND PERIMETER TO
PREVENT EXCESSIVE SEDIMENT FROM ENTERING THE POND. THE POND
PERIMETER SHALL BE MOWED ON A QUARTERLY BASIS. (DO NOT MOW WETLAND PLANTS)
2. TO PRESERVE THE HYDRAULIC CAPACITY OF THE POND SYSTEM AND TO PREVENT
RUNOFF FROM BACKING UP, INLET AND OUTLET AREAS SHALL BE KEPT CLEAR
OF HEAVY VEGETATION.
B. EROSION PROBLEMS
THE ENTIRE POND AREA SHALL BE INSPECTED QUARTERLY FOR SIGNS OF EROSION,
PAYING SPECIAL ATTENTION TO THE FOLLOWING AREAS:
1. RILL EROSION OF THE POND EMBANKMENT SHALL BE REPAIRED BY FILLING
THE SMALL CHANNELS WITH SUITABLE SOIL, COMPACTING, AND SEEDING.
INSPECT FOR, AND IMMEDIATELY REPAIR, ANY EROSION ON THE DAM
EMBANKMENTS.
2. ERODED AREAS AT PIPE INLET OR OUTLET AREAS SHALL BE FILLED WITH
GOOD COMPACTABLE SOIL AND COVERED WITH GEOTEXTILE AND RP -RAP.
3. OPEN CHANNELS WITH ERODED AREAS SHALL BE SEEDED/SODDED AND
PROTECTED WITH TEMPORARY VELOCITY DISSIPATION (SUCH AS EXCELSIOR
MATTING, STRAW BALES, ETC.).
C. BLOCKAGE OF OUTLETS
THE WET DETENTION POND'S ORIRCE(S), PRINCIPAL SPILLWAY (CONTROL STRUCTURE), AND THE
EMERGENCY (SLUICE GATE) SPILLWAY SHALL BE INSPECTED FOR BLOCKAGE THAT WOULD IMPAIR
THE POND'S WATER QUALITY AND HYDRAULIC FUNCTIONALITY.
1. THE LOW FLOW ORIFICE SHALL BE INSPECTED FOR BLOCKAGE TWICE A
MONTH AND AFTER LARGE STORMS.
2. TO ENSURE THE HYDRAULIC CAPACITY OF THE OUTLET STRUCTURE, OUTLET PIPE SHALL
BE VISUALLY INSPECTED FOR BLOCKAGE ONCE A MONTH AND AFTER LARGE
STORMS. THE OUTLET PIPE SHALL BE CLEAR OF TREE LIMBS, SEDIMENT
ACCUMULATION, ETC. VEGETATIVE GROWTH IN THE CONTROL STRUCTURE SHALL BE
REMOVED PROMPTLY SO THAT THE DESIGN CAPACITY OF THE OUTLET PIPE IS MAINTAINED.
D. SEDIMENT ACCUMULATION
THE FOREBAY MUST BE DREDGED WHEN SEDIMENT DEPOSITION IN THE FOREBAY
EXCEEDS THE DESIGNED SEDIMENT STORAGE CAPACITY FOR THE FOREBAY. AN
INDICATION OF WHEN THE FOREBAY SEDIMENT CAPACITY IS EXCEEDED IS WHEN
SEDIMENT BARS ARE VISIBLE NEAR THE INLET DISCHARGE OR WHEN THE SEDIMENT
LEVEL AT THE INLET TO THE POND IS LESS THAN ONE FOOT BELOW THE NORMAL POOL
SURFACE. DEPTH MEASUREMENTS RELATIVE TO THE NORMAL SURFACE ELEVATION
(BOTTOM OF WATER QUALITY ORIFICE) SHALL BE TAKEN AT SEVERAL LOCATIONS
AROUND THE POND (TYPICALLY FOREBAYS WILL NEED TO BE DREDGED EVERY 5 TO 10
YEARS).
DREDGING OF THE FOREBAY (AND PERMANENT POOL AREA, IF NECESSARY) WILL BE
ACCOMPLISHED BY USING A DREDGE LINE, "GRADE ALL" OR SIMILAR PIECE OF
MACHINERY.
REPLACE PLANT MATERIAL THAT IS DAMAGED AS PART OF DREDGING ACTIVITIES. REPLANT PER
ORIGINAL SCHEDULE.
E. BASIN DRAINING
PUMPING SHALL BE REQUIRED TO COMPLETELY DEWATER THE BASIN.
