Multi-Benefit Flood Protection Project: Multi-benefit projects are designed to reduce flood risk and enhance fish and wildlife habitat by allowing rivers and floodplains to function more naturally. These projects create additional public benefits such as protecting farms and ranches, improving water quality, increasing groundwater recharge, and providing public recreation opportunities, or any combination thereof.

In 2012, California’s Central Valley Flood Protection Board adopted the Central Valley Flood Protection Plan (CVFPP), which established a new framework for system-wide flood management and flood risk reduction in the Sacramento and San Joaquin River Basins.

The CVFPP takes a new approach to flood protection that works with communities to improve flood safety while also supporting other public benefits such as clean water, natural areas that support fish and wildlife, and recreational areas in Central Valley communities where people can enjoy nature’s benefits.

The CVFPP aspires to improve flood protection for over one million people and $70 billion in homes, businesses and infrastructure with the objective of providing 200-year flood protection to urban areas while reducing flood risks to small communities and agricultural lands.

This site is a resource to support a multi-benefit approach to improving flood protection, meant for everyone working to make the CVFPP a success.


Q: What is 200-year flood protection?

A: 200-year flood protection is another way of saying there is a 1 in 200 chance of flooding in any given year. Because the Central Valley is vulnerable to large flood events, the legislature passed the Central Valley Flood Protection Act of 2008 to provide additional protection to the region.

Q: Why does it matter?A: Millions of Central Valley residents live and work in high-risk flood zones. Courts have ruled that our government could be liable for billions of dollars in damages if a major flood damages private property, not to mention the cost of repairing levees, roads, and the state’s water transport system. Flooding could even impact the delivery of drinking water to over 25 million Californians from San Diego to Redding.  Every Californian has a stake in reducing flood risk in the Central Valley.
