cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth. Removed sediment shall be disposed of in an appropriate
manner and shall not be handled in a manner that will adversely impact water quality (i.e. stockpiling near a
wet detention basin or stream, etc.).

5. Remove cattails and other indigenous wetland plants when they cover 75% of the basin surface. These
plants shall be encouraged to grow along the basin perimeter.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through
the emergency drain shall be minimized to the maximum extent practical.
7. All components of the wet detention basin system shall be maintained in good working order
I acknowledge and agree by my signature below that I am responsible for the performance of the above
maintenance procedures. I agree to notify DWQ of any. problems with the system or changes in the name of the

IV._ INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion,
trash accumulation, grass cover, and general condition.
2. Repair eroded areas immediately;rre-seed as necessary to maintain adequate vegetative cover, mow
vegetative cover to maintain a maximum height of six inches, and remove trash as needed.
3. After every runoff producing rainfall event and at. least monthly inspect the bypass/overflow structure for
blockage and deterioration. Remove blockage and repair structure to originally approved design
specifications.
4. Remove accumulated sediment annually or when depth is reduced to 75% of the original design depth.
Restore depth to original design depth without over -excavating. Over -excavating may cause the required
water table separation to be reduced and may compromise the ability of the system to perform as designed.
5. If DWQ determines that the system is failing, the. system will immediately be repaired or replaced to
original design specifications. If the systemcannot be repaired to perform its design function, other
stormwater control devices as allowed by NCAC 2H .1000 must be designed, approved and constructed.
I acknowledge and agree by my signature below that I am responsible for the performance of the above
maintenance procedures. I agree to notify DWQ of any problems with the system or changes in the name of the
project, responsible party, or address.

STORMWATER MANAGEMENT PERMIT APPLICATION FORM
LOW DENSITY SUPPLEMENT
This form may he photocopied for use as an original
A low density project is one that meets the appropriate criteria for built upon area and transports stormwater
runoff primarily through vegetated conveyances. Low density projects should not have a discrete stormwater
collection system as defined by 15A NCAC 2H .1002(18). Low density requirements and density factors can be
found in 15A NCAC 2H .1005 through .1007.
I. PROJECT INFORMATION (please complete the following information):
Project Name :
Contact Person: XO A01APIK 11l tfho _ Phone Number: (2$2) �4�� 9 0�
Number of Lots: Square Feet Per Lot*: N I A
*If lot sizes are not uniform, attach a table indicating the number of lots, lot sizes and allowable built upon area
for each lot.
H. BUILT UPON AREA
See the Stormwater Management Permit Application Attachment A for specific language that must be recorded
in the deed restrictions for all low density projects.
For uniform lot sizes, complete the following calculation in the space provided below where:
• SA Site Area - the total project area above Mean High Water. Wetlands may be excluded when the
development results in high density pockets. .
• DF Density Factor - the appropriate percent built upon area divided by 100.
• RA Road Area - the total impervious surface occupied by roadways.
• OA Other Area - the total area of impervious surfaces such as clubhouses, tennis courts, sidewalks, etc.
• No. Lots is the total number of lots in the subdivision.
• BUA/Lot is the computed allowable built upon area for each lot including driveways and impervious
surfaces located between the front lot line and the edge of pavement.
Calculation:
SA x DF - RA - OA = BUA
No. Lots Lot
