This happened in ~1993. Crazy. People flew from Salinas to Monterey (<20 miles) as the Peninsula was cut off. Shortly after that, I had a business flight and flew out of Monterey and passed Watsonville (35 miles away), where ~1000 "trash" cans (used for storing Strawberries for making jam at Smuckers) had floated away and into the valley. In Carmel, people got their houses fixed up after the flooding, and got re-flooded in March the same year.
