STRATEGY 8
Protecting coastal groundwater basins from seawater intrusion Groundwater basins located along Los Angeles County’s coastline will need continued protection to limit the continued pressure of seawater intrusion from sea level rise that is predicted to result from climate change. Although existing barriers are solely owned and operated by the Los Angeles County Flood Control District, they benefit multiple agencies and stakeholders throughout Los Angeles County. As such, the ability to maintain and possibly further enhance protections and groundwater supply could benefit from regional collaboration.
Actions to support this strategy
8.1 Determine vulnerability of barrier
programs to seawater intrusion as a result of future sea level rise and evaluate opportunities to optimize barrier system operations.
8.2 Explore partnership opportunities to
create further investments and increase recharge potential at barriers to enhance protection and increase groundwater supply

On Target
Protecting our coastal groundwater basins from future sea water intrusion is critical to meeting the target to optimize production of groundwater by maintaining at least 700,000 AFY baseline groundwater production.
