To reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site, based on historical conditions and undeveloped ecosystems in the region.
Use low-impact development (LID) practices to infiltrate, evapotranspirate, collect and reuse water onsite from 25% of the impervious surfaces for the 95th percentile storm event.
Establish and implement an annual inspection and maintenance program of all rainwater management facilities to assure continued performance.
Document the annual inspections, including identification of areas of erosion, maintenance needs, and repairs. Perform necessary maintenance, repairs, or stabilization within 60 days of inspection.
