A previous vulnerability report conducted for the San Francisco Bay Area was issued earlier this year, which highlighted areas vulnerable to wildfire – combined with the resulting land erosion and flooding from storms – along with higher precipitation, sea level rise, and storm surges.
That report showed that the 2016-2017 storm season caused severe flooding, landslides and coastal erosion totaling over $1.2 billion in highway damages statewide. Nearly $390 million of those damages occurred in the Bay Area.MORE NEWS: Multiple Agencies Ramp Up Search For Rogue Coyote That Bit 5 Lamorinda Victims
