The Flooding Character of Sacramento County

River and roadway flooding from strong winter storms is a significant flood character in Sacramento County. Recent events in February 2025, for example, brought multiple inches of rain to the valley and foothills, leading to widespread flooding, road closures, and search and rescue efforts. Another event in early February 2025 also caused river and roadway flooding due to heavy rain.

Homeowners in Zone A, which has seen the highest number of flood insurance claims with an average water depth of 2.1 feet, should pay close attention. Residents in Zone X_UNSHADED, despite fewer claims, have experienced higher average payouts and shallower water depths, indicating potential risk. Properties located near rivers or in areas prone to inundation should be aware of their specific flood risk.
