The region of Los Angeles between downtown and Long Beach is ideal for such projects because that is where the need is greatest. This region of LA has the largest concentration of groundwater contamination, emissions, and hazardous waste. It also has the highest density of poverty, unemployment, public health concerns, and more—making it where the environmental, social, and economic impact would be largest. LA has already invested significantly in the area’s metro transit, meaning there may be opportunities to capitalize on or collaborate with existing development. Decentralized stormwater projects could provide additional benefits across environmental, social, and economic dimensions.
