General LID


LIDI works in collaboration with the California Stormwater Quality Association (CASQA), including providing LID resources on their LID Portal. There is a wealth of material located on their site, including technical, economic, and regulatory information, and training opportunities. The LID Portal is relatively new, but contains some key resources, which are constantly being updated.
