Low Impact Development

What is LID?

Low Impact Development (LID) is a stormwater management approach that mimics nature’s hydrologic cycle by designing new development to slow down stormwater runoff (attenuation), increase groundwater recharge (infiltration), and reduce pollutant loads in stormwater runoff by filtering water through plants and soils (treatment). LID strategies include many techniques to reduce stormwater runoff from developed land, including:

rain gardens

rainwater tanks and cisterns

green roofs

native plant landscaping

stream buffers

tree planting

previous pavement

LID Projects on the UC Berkeley Campus

The booklet, Reinventing Stormwater: A Tour of the UC Berkeley Campus, highlights innovative design features of LID water infrastructures on campus.

LID Regulations

As of July 1, 2015, UC Berkeley is required to treat stormwater from new development and redevelopment using LID techniques.

LID Resources

Check out these CASQA guidelines on how to design and build stormwater treatment facilities.

There are many LID resources out there on the web. Here are just a few to get you started:
