History

Historical Context

The Great Flood of 1862, caused by unprecedented rainfall and snowmelt, submerged much of California, leading to the temporary relocation of the state capital from Sacramento to San Francisco. This disaster resulted in an estimated 4,000 deaths and $100 million in damages, prompting significant improvements in flood management. The recent October 2025 storm, echoing these historical challenges, highlights ongoing vulnerabilities in California's infrastructure.
