Area of Special Biological Significance (ASBS)
La Jolla is home to a fantastic array of marine life. You may have seen some of these creatures—spiny lobsters, abalone, giant sea bass, vermillion rockfish, schools of leopard sharks—up close while wading, snorkeling or diving. Or maybe you were content to appreciate La Jolla’s serene ocean beauty from shore. Regardless of how you choose to experience it, you know that this area is special. It is designated by the State of California as an Area of Special Biological Significance (ASBS)?
While clean ocean water is a necessary component of healthy oceans, our local water quality is under attack from a variety of pollution sources and related activities. In La Jolla, there are several factors that can negatively impact the health of the ASBS, including:
Discharge of Wastewater or Pollutants. Inadvertent discharge of human sewage and waste from sewage treatment plants into marine areas can release dangerous bacteria into the ocean and alter the water’s chemical composition. Chemical changes from pollutant scan also poison marine life and deplete the amount of available oxygen in the water. As a result, wastewater and pollutant discharges are not allowed in any ASBS.
Litter. La Jolla Shores is visited by approximately 2 million people each year. Unfortunately, many people leave their litter behind on the beach. Common debris items found at La Jolla Shores include plastic bags, beverage containers, food wrappers and straws. Cigarette butts are by far the most common litter item.
Storm water Runoff. As rain washes over streets, parking lots and lawns it picks up numerous pollutants, pesticides and other contaminants. Eventually, this storm water makes its way to the ocean and sends a toxic cocktail into the sea. This type of pollution is of particular concern because it is difficult to pinpoint the exact source and hard to control. The discharge of storm water into an ASBS is generally prohibited, and is only allowed if the discharge will not compromise protection of ocean waters for beneficial uses.
A collaborative watershed approach will be used to institute effective and efficient strategies to address pollution within this urban watershed that drains to both ASBS. Coast Guard is working with Scripps Institution of Oceanography and the City of San Diego to implement the La Jolla Shores Coastal Watershed Management Plan.
