California does indeed have this problem occasionally. During the recent summer, there were 3 or 4 hurricanes along the coast of Baja, which were quite powerful but not strong enough to travel all the way to the US coast of California. However, the enormous waves generated in those hurricanes were some of the largest seen in many decades, with swells over 20 ft (7 meters) for days at a stretch. These waves eroded great sections of beach sand, especially at the city of Seal Beach, allowing tides and swells to flood Seal Beach one night. Fortunately for Seal Beach, there was sand available from river dredging in Orange County which was given to rebuild the sand berms and levees to restore protection from future storms. Ordinarily that sand would have replenished itself as the rivers carry it to the deltas into the ocean, but that would have taken several years.
