Legacy Park will serve as what officials refer to as an environmental cleaning machine designed to reduce pollution and bacterial contamination before the water hits Malibu Creek, Malibu Lagoon and Surfrider Beach.
In 2006, the city of Malibu constructed a stormwater treatment facility at the corner of Civic Center Way and Cross Creek Road. The facility cleans and disinfects rainwater and urban runoff using an ozone treatment process.
Stormwater is collected through a series of storm drains, and pumps send that water to the facility. Flows of up to 1,400 gallons per minute can be captured and treated.
Flows from 337 acres in Malibu are currently collected within three major storm drains. Eventually, all that water will be pumped to Legacy Park, which has been designed to accept as much as 2.6 million gallons of stormwater and urban runoff.
Once the stormwater has been collected, it will be sent over to the city's existing treatment facility.
During heavy rains, the clean stormwater will be sent off to Malibu Creek. When there is less rain, the treated water will be re-used for park irrigation.
Legacy Park is scheduled to be completed by October 2010.
