Coastal Retreat in California's Central Coast Region, specifically Southern [[Monterey Bay]], has the fastest rate of erosion in California.<ref name="HapkeEtAl.2006"/> Since the retreat is occuring in the [[Monterey Bay National Marine Sanctuary]], scientists are determined to find possible mitigation efforts, reasons for high rates, and, specific hot spots.
