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.
3. 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

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

When using the Division SA/DA tables, the cot cet SA/DA ratio for permmnent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR LIMP manual provides design tables for both 85% TSS removal and 90% TSS removal.

111. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
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) 0 does (does not incorporate a vegetated filter at the outlet.
This system (check one) 0 does OCdoes not incorporate pretreatment other than a forebay.
Form SWU-102 Rev 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
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 (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 3 .0 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 2.25 feet in the forebay, the sediment shall be removed.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
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.

When using the Division SA/DA tables, the cot rcel SA/DA ratio for pennanent pool sizing should be computed based upon the
actual impervious % and pennanent pool depth. Linear interpolation should be emploved to determine the correct value for non-
standard table entries.
In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR 13MP manual provides design tables for both 85% TSS removal and 90% TSS removal.
