Project: Magic Johnson Stormwater Management Project

Description: County Department of Park and Recreation (DPR), in partnership with the County of Los Angeles Department of Public Works (DPW), developed the stormwater recycling system that will provide a cleaning mechanism for the EMJ South Lake and create a sustainable irrigation system for the site that recycles local stormwater. In support of these water infrastructure improvements and sustainability efforts in the reconfiguration of the EMJ South Lake, the MJ Stormwater project will include the creation of a biofiltration garden that integrates native riparian vegetation to imitate a natural wetland filtration process, allowing for filtration of dirty runoff water and greywater to be cleaned and stored in the South Lake. In addition, the biofiltration garden will serve a dual purpose by providing irrigation to the park and acting as a storage and overflow zone that will ensure only clean water flows from the Lake to the Compton Creek which runs through Willowbrook (a subwatershed of the Los Angeles River). With the new design, the South Lake will be reborn as a natural-looking body of water that circulates and cleans stormwater and play a major part in revitalizing the park and natural habitat for health of the community and local wildlife. The Project will also help increase the avian habitat within EMJ by introducing nesting structures for herons and other bird species.
