Forty Miles of Creek, Six Adaptation Projects

Santa Clara County

By Robin Meadows

In 2017, a perfect storm hit the City of San Jose in Santa Clara County. Coyote Creek, which winds through the heart of the city, overtopped its banks, flooding businesses and hundreds of homes up to depths of six feet. Thousands of people were evacuated and property damages exceeded $70 million. “If I’ve learned anything in my 25 years here, it’s that you have to give creeks room to move, which also creates more resilience to climate change,” says Valley Water district planning engineer Afshin Rouhani, explaining that this slows the water, decreasing flooding and bank erosion. As winter rains intensify with climate change, flooding will worsen in the county. In the hills edging the Santa Clara Valley, wildfire is also a threat. On the valley floor, where most of the people live, major threats in addition to riverine flooding are blistering hot summer days and shoreline flooding as San Francisco Bay rises. The Coyote Creek system—1,500 miles of waterways that drain a 350-square-mile watershed—connects half a dozen elements that are key to climate adaptation, from reservoirs to creek confluences to shoreline levees.

California will spend big bucks on beavers to try to boost their numbers and reap some of the benefits—including slowing wildfire—these ecosystem engineers can provide.

After years of advocacy by beaver “believers,” the state has allocated funding for a beaver restoration program. The $1.67 million in license plate funds for fiscal year 2022-23 and $1.44 million the following year represents a new way of thinking about beaver management in California, says Kate Lundquist, of the...

Changes to water are at the heart of the documented and further expected impacts;...
