Your help needed NOW to fast-track critical dam safety for Silicon Valley

June 26, 2020
Anderson dam and reservoir

Valley Water’s efforts to fix Anderson Dam reached an important milestone recently when State Assembly Bill 3005, The Expedited Dam Safety for Silicon Valley Act, passed the California Assembly with overwhelming bipartisan support.

But AB 3005 needs your support to help protect our communities and ensure the bill becomes law. See below for how you can help.

Anderson Dam, located in Morgan Hill, is vulnerable to failure during a major earthquake. If that failure were to happen during the rainy season when the reservoir is full, an uncontrolled release of water would flood an area extending more than 30 miles north to San Francisco Bay and 40 miles south to Monterey Bay. Many cities, including San José, Santa Clara, Sunnyvale, Milpitas, Morgan Hill, Gilroy, and Watsonville would see catastrophic flooding.

Notably, this flood zone includes the economic center known as Silicon Valley, which generates more than $3 trillion annually in global economic activity, creating jobs and supporting vital government services at the local, state, and federal level. Flooding in this area would have far-reaching impacts.

Valley Water’s top priority is to fix Anderson Dam and prevent this devastating loss of life and destruction of property from happening.

AB 3005 will fast-track state permitting and help ensure expert construction of Anderson Dam. The Anderson Project will remove and replace the dam to protect our regional water supply, construct a larger outlet tunnel for dam safety and incidental flood protection, and provide environmental improvements along Coyote Creek.

Authored by Assemblymember Robert Rivas (D-Hollister), AB 3005 now goes to the State Senate for further consideration. There is strong public support for expediting the Anderson Dam project and the California Legislature needs to hear from the communities that would be impacted if the dam were to fail.

Dear Assemblymember Rivas,

I strongly support AB 3005, your bill to fast-track the Anderson Dam Seismic Retrofit Project. As you know, the failure of Anderson Dam during a large earthquake would bring catastrophic loss of life and property, flooding the heart of Silicon Valley and beyond. AB 3005 will ensure the State of California does its part to expedite this critical public safety, water supply, and environmental project to remove and replace Anderson Dam. I urge the Legislature to pass and the Governor to sign this vitally important legislation.
