19."Low impact development (LID)" uses site design and stormwater management to
maintain the site's pre -development runoff rates and volumes. The goal of LID is to
mimic a site's predevelopment hydrology by using design techniques that infiltrate,
filter, store, evaporate, detain, and/or biotreat stormwater runoff on or near the site. At
the site scale, GSI is a subset of LID. As LID practices are often implemented with
GSI, these concepts are referred together as LID/GSI.
