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 pondibasin 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 MAINTENANCE/INSPECTION 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.
