Regular maintenance of stormwater facilities is necessary for proper function of the drainage system. All stormwater maintenance will be the responsibility of the property owners. Maintenance items include removing debris from inlet grates, cleaning and flushing pipes, cleaning manhole sumps, and establishing ground cover after construction. Clear weeds & vegetation from pond orifices. The infiltration facilities will be cleaned and maintained by access risers installed on the underground stormwater retention system per “Contech Inspection and Maintenance Guide”. Maintenance and inspection of all stormwater components shall be completed annually and after large rain events. Annual inspections are best practice for all underground systems while multiple inspections throughout the first year of operation are highly encouraged. The expected life and replacement schedule of the stormwater infiltration system is 75 years and the pond should be inspected after every major storm event to see if replacement is necessary. A financial plan should be implemented to insure proper inspection, maintenance, operation and replacement needs are met.
