WORTH, TX DETENTION SYSTEM OPERATION AND MAINTENANCE PLAN The detention pond located at 5701 Merrymount Road; Ft. Worth, Texas contains a storm water detention basin to mitigate the impact of increased runoff due to existing development of the land. In order to maintain functionality and reduce the risk of flooding, these systems should be inspected and maintained on a regular basis by the property owner. This plan outlines the requirements and procedures for ensuring the system works properly. System Description The detention system consists of a single facility that serves the immediate area. The purpose of this facility is to restrict runoff from storm events which flows at a higher rate due to impervious areas (concrete paving, building roof, etc.) and release it at a steady rate like when the land was undeveloped. This restriction of flow occurs at the outlet structure, which consists of an outlet structure located generally in northwest portion of the property which discharges into the public storm system through an existing 24” Storm Drain Pipe. The outlet structure consists of a 2’ by 1’ opening for the 100-year rainfall event. The basin also has a spillway designed for any extreme event, or in case of a blockage at the outlet. The spillway was designed to convey more than a 100-year rainfall event. System Maintenance Inspection and general maintenance of the detention facility is not complex and should be done on a regular basis. Outlined below are guidelines for the inspection and maintenance procedures. These are for routine maintenance only. The system should be inspected immediately after a storm event if the basin ponds above the bottom of the spillway. - Visual inspections conducted every six (6) months of all components, including: o The outflow area on the downstream side of the spillway and outlet, o The soil area around the rip rap for any signs of washout or rutting o The retaining wall for any cracks or loose rock and repair as required. o The outlet structure for any damage or deterioration. - Remove any trash within the detention basin, the outlet pipe and rip rap area and the grate on the outlet structure. - Mow the entire pond at least once every three (3) months. - Sediment removal from the detention/retention facility when the retention pond is 4’ or less. - A log shall be kept of maintenance actions, and inspections. o The log should document the condition of the detention system’s primary components, mowing, and silt, litter and debris removal dates. - 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. 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, though, or out of the system. Periodic silt removal shall occur when the pond’s storage volume is reduced by more than 10%. Silt shall be removed, and the pond 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. 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. 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. Maintenance of Public and Private Storm Lines Private storm drain lines as identified on the construction plans shall be the landowner and association, its successors and assigns identified in the storm water facility maintenance agreement. In order to provide for maintenance of public storm drain lines adjacent to ponds or City requested dewatering of pond, the pond water surface elevation will be drawn down below the storm drain pipe flow line elevation at the pond outfall by the landowner and association, its successors and assigns. The landowner and association, its successors and assigns shall be provided notice 72 hours in advance of the intended maintenance and will be required within to draw down the pond to a level suitable to allow the City, its authorized agents and employees, the ability to access, clean, and flush public storm drain lines. In the event the landowner and association, its successors and assigns fail to draw down the pond water surface elevation to a suitable elevation at the time of the prescribed maintenance or in the event of an emergency, the City, its authorized agents and employees, may enter upon the facility property and take whatever steps necessary to draw the pond water surface elevation and maintain the public storm drain lines and to charge the costs of such activities to the landowner, its successors and assigns. The City is not responsible for raising the water surface elevation in the pond after maintenance. � � � s K W H N J Y V W _ V Z � H U W a � Z � H J V Q � Z � � Z W � W�/ Y� u; +� m � � f6 X N H L L 0 � � C a° " C � O � O 'a� p� C � N � � 3 � �� C 3 L O L � � A � i � � � � � � fC Z v � .O a � m � N u � Q. � c � +� c a� � E 0 v a v C "a N N � O y Z G � v v N Q � C v � � � � +, o +� � L � L � O T a.., (6 � O = t C �Q � O � � c�E � L �� O O Y . � V� U L O C O � � .� � � � � � � � � 0 O � � O � � �O o t�u � Q Y � � cLo v � � � o .� v � -� L T � � � � L t � � O �-' a"' i � O � `� v � 7 3 � O � 3 � � � � � � N � O � .� � � ca .
