POCKET WETLAND OPERATION AND MAINTENANCE AGREEMENT
for
Autumn Park Townhomes
Holly Springs, North Carolina
The pocket wetland system is defined as the wetland detention basin, pretreatment including
micropools and the vegetated filter if one is provided.
Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the pocket wetland 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.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly
to maintain proper functioning.
4. For stormwater wetlands: If the elevation of the marsh areas exceed the permanent pool
elevation, the sediment should be removed to design levels. This shall be performed by
removing the upper 6 inches of soil and stockpiling it. Then the marsh area shall be excavated
six inches below design elevations. Afterwards the stockpiled soil should be spread over the
marsh surface. The soil should not be stockpiled for more than two weeks. 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 pocket wetland system or stream, etc.).
5. For wetlands: Wetland planting densities in the marsh areas should be maintained by replanting
bare areas as needed. Wetland plants should be encouraged to grow in the marsh areas.
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 pocket wetland system shall be maintained in good working order.
8. Level spreaders or other structures that provide diffuse flow shall be maintained every six
months. All accumulated sediment and debris shall be removed from the structure, and a level
elevation shall be maintained across the entire flow spreading structure. Any down gradient
erosion must be repaired andlor replanted as necessary.
