Exhibit "C"
CITY OF FORT WORTH STORMWATER FACILITY
OPERATION AND MAINTENANCE PLAN
The only responsibility the City of Fort Worth has in the operation and maintenance of
this Facility is inspection.
General Maintenance Procedures
The structural and functional integrity of the Facility shall be maintained at all times by
removing and preventing drainage interference, obstructions, blockages, or other adverse
effects into, through, or out of the system.
Periodic silt removal shall occur when standing water conditions occur or the pond's
storage volume is reduced by more than 10%. Silt shall be removed and the pond/basin
returned to original lines and grades shown on the approved engineering plans. In
addition, corrective measures are required any time a basin does not drain completely
within 72 hours of cessation of inflow. NO STANDING WATER IS ALLOWED in
basins designed for dry detention purposes.
Accumulated litter, sediment, and debris shall be removed every 6 months or as necessary
to maintain proper operation of the basin. Disposal shall be in accordance with federal,
state and local regulations.
Detention facilities shall be mowed monthly between the months of April and October or
anytime vegetation exceeds 12-inches in height.
To prevent debris from entering and clogging the downstream storm sewer system a wire
mesh screen or similar screening device shall be installed over the outlet until final
acceptance.
4. PREVENTIVE MAINTENANCEANSPECTION
• Visual inspections of all components will be conducted every 6 months.
• A log shall be kept of maintenance actions, and inspections. The log should
document the condition of the detention system's primary components, mowing,
and silt, litter and debris removal dates. Document aeration of the basin bottoms
and replanting to prevent the sealing of the basin bottom.
• Written maintenance and repair records shall be maintained by the party or
parties signing the attached Agreement and shall be provided to the City upon
request.
