LOS ANGELES — In early October, the City of Malibu opened its new Legacy Park, which features a first-of-its-kind technical advancement in addressing water quality and supply along with meeting recreational and habitat needs. The park serves as a multi-purpose water resources facility designed to remove bacteria, metals, nutrients, and debris from the stormwater runoff affecting Malibu Creek, Malibu Lagoon, and ultimately, the Pacific Ocean.
Legacy Park, described as an "environmental cleaning machine," is capable of capturing up to 2.6 million gallons per day of stormwater and urban runoff for treatment and disinfection.
"This one-of-a-kind park in the heart of Malibu creates a legacy of ocean protection and environmental conservation for generations to come," said Malibu mayor Jefferson Wagner.
"This project may be the only multi-benefit regional facility in southern California that captures, stores, treats, disinfects, and then uses stormwater and urban runoff for irrigation," said Ken Susilo, PE, D.WRE, CPSWQ, Principal of Geosyntec Consultants. "It puts an entire segment of the City of Malibu into compliance with stringent Bacteria TMDL [Total Maximum Daily Loads] requirements, while also creating valuable, rare and diminishing habitat along the California Coastline."
Geosyntec Consultants, as a subconsultant to RMC Water and Environment, completed some key aspects to the Legacy Park project. These include: stormwater consulting and design; hydrologic modeling; groundwater mounding analysis; geotechnical consulting and design; field investigation and reporting; and permitting. Other consultants were Royston Hanamoto Alley & Abey, which provided landscape architecture, and Dr. Richard Ambrose of UCLA, who provided expert ecological consultation.
"Great day for the community, fantastic day for the State, and historic day for the environment," said Jim Thorsen, Malibu city manager.
