Sonoma County Water Agency Local Hazard Mitigation Plan


    The 30-day public comment period for the DRAFT 2018 Sonoma County Water Agency Local Hazard Mitigation Plan (LHMP) closed on May 25, 2018. No public comments were received. FEMA completed their review of the LHMP on September 2, 2018 and determined the LHMP is eligible for final approval pending its adoption by the Sonoma County Water Agency’s Board of Directors. The meeting for the Board to approve and adopt the LHMP is set for October 9, 2018.


    What is the LHMP?

    A Local Hazard Mitigation Plan (LHMP) forms the foundation for a community's long-term strategy to reduce disaster losses and break the cycle of disaster damage, reconstruction, and repeated damage. The planning process is as important as the plan itself, and must include public and stakeholder involvement. LHMP’s are public documents that create a framework for risk-based decision making to reduce damage to lives, property, and the economy from future disasters. Hazard mitigation is sustained action taken to reduce or eliminate long-term risk to people and their property from hazards. The Federal Government passed the Disaster Mitigation Act of 2000 which encourages and rewards pre-disaster planning at all levels of local and state government. The Federal Emergency Management Agency (FEMA) requires LHMPs to issue grant funding for pre-disaster and hazard mitigation projects.

    Since 2004 the Sonoma County Water Agency has initiated a natural hazard reliability improvement program, which included creating the Water Agency’s first LHMP in 2008. This LHMP was updated in 2013, and includes a priority listing of hazard mitigation projects.

    The Water Agency must update its LHMP every five years to ensure it remains relevant to current events and system conditions and to meet regulations set forth by FEMA. In particular, staff will update the Water Agency’s vulnerabilities and risks, as well as the prioritized listing of hazard mitigation projects.
