The City of Los Angeles Transforms an Industrialized Site to a Riverside Park

摘要

The Albion Riverside Park Project is a Proposition O project in the City of Los Angeles (City). The project objective is to provide water quality benefits to help the City meet their Total Maximum Daily Load (TMDL) goals set by the Los Angeles Regional Water Quality Control Board (LARWQCB), and to provide beneficial recreational park use for the local community. The project site was a challenge for stormwater management solutions due to its history of contamination brought on by previous onsite industrial activities. The site was remediated and Low Impact Development (LID) techniques were strategically configured to meet water quality goals. Flows from the 121-hectare (300-acre) watershed are diverted to two pretreatment units before entering the underground infiltration galleries. Stormwater captured within the infiltration galleries percolate into the underlying soils, recharging the groundwater. Once the system reaches capacity, it is shut down with an actuated valve to prevent surcharge.
