The County’s Hazard Mitigation Plan (HMP) is a multi-jurisdictional effort that inventories the natural hazards that Yolo County is most vulnerable to, assesses risks to community members, resources, buildings, and critical facilities, and identifies and prioritizes actions for risk reduction based on a comprehensive area-wide mitigation strategy. Every five years, the local Hazard Mitigation Plan is updated and submitted to the Federal Emergency Management Agency (FEMA) for review and approval.

An approved hazard mitigation plan is required under the Federal Disaster Mitigation Act of 2000 (Public Law 106-390) to ensure continued eligibility for future disaster grant funding opportunities under the Robert T. Stafford Act., including FEMA’s Hazard Mitigation Grant Program (HMGP), Building Resilient Infrastructure and Communities (BRIC), and Flood Mitigation Assistance (FMA).

The 2023 Yolo County Multi-Jurisdictional Hazard Mitigation Plan was approved by FEMA on October 15, 2024.

Emergency Operation Plan 2024  

In 2024, the County completed an update to its Emergency Operations Plan. The Plan outlines the County’s planned response to significant emergencies and major incidents caused by natural disasters, technological failures, or human-made crises within or affecting the County of Yolo. While it does not cover every possible scenario, the Plan provides guidelines for the County's response to major incidents. It serves as the primary guide for the County's management of and recovery from actual or potential emergencies and disasters within its geographic boundaries. The plan outlines methodologies for conducting emergency operations, functional-based emergency planning, and community-wide emergency response strategies. It also emphasizes the inclusion of culturally diverse populations and individuals with disabilities, access and functional needs, and continuity of government during emergencies or disasters.

Yolo County has finalized and adopted its Drought Resilience Plan, which outlines how the County and partner agencies will address water supply vulnerabilities for rural residents, domestic wells, and small water systems. Developed under SB 552 with state support, the plan identifies drought risks and lays out short- and long-term strategies to improve local water resilience.

Adopted Drought Resilience Plan 2026

About SB 552

In September 2021, Governor Gavin Newsom signed into law Senate Bill (SB) 552 (Hertzberg), which requires state and local governments to share responsibility in planning and responding to water shortage events, particularly for state small water systems and rural communities supplied by domestic wells. Through SB 552, the California State Legislature identifies counties as the best-suited government entity to provide the needed leadership to improve water resilience for state small water systems and domestic wells.

Under SB 552, all counties in California are required to prepare a County Drought Resilience Plan (County DRP) to achieve meaningful and long-term improvements in water resilience for their residents. In addition to the development of a County DRP, SB 552 directs counties to establish a long-standing County Drought and Water Shortage Task Force (Task Force) to cultivate the continued practices of drought planning and improving long-term water resilience.
