Areas of Special Biological Significance
What is an ASBS?
Areas of Special Biological Significance (ASBS) are protected coastal areas created to preserve local marine ecosystems. There are 34 ASBS along California's coast that support a rich variety of aquatic life. ASBS regulations prohibit pollutants from entering the ocean through private and public storm drains and natural streams. Malibu is home to a portion of ASBS No. 24, which stretches 24 miles from Latigo Point beyond the County Line to Laguna Point (in the Point Mugu area). The City of Malibu continues to prove itself as an environmental leader by working diligently to protect the 11,842 acres of marine habitat in ASBS No. 24.
