Monitor all stormwater mitigation features, including natural areas as well as mechanical harvesting equipment, to gauge retention efficiency and ensure proper function.
Investigate opportunities for increased stormwater mitigation (based on the inventory results) through water harvesting techniques or modifying surface areas to increase the amount of pervious surface.
If cisterns, detention ponds, or other stormwater collection systems exist on site, assess their capacity and the area of surfaces from which they collect water, based on design documents or other system information.
Perform a site inventory cataloging surface types, such as asphalt, concrete, roof areas, and landscaped areas. Use the LEED template to assess the percent of stormwater managed based on site perviousness.
