2028 MJLHMP Update
Riverside County and 40 participating jurisdictions initiated the five-year update of the Multi-Jurisdictional Local Hazard Mitigation Plan (MJLHMP) in the Summer of 2026.
The goal of the 2028 Riverside County MJLHMP is to save lives and property through the reduction of hazard vulnerability for the unincorporated county. During the course of this planning project, county and local leaders and the community will work in tandem to identify risks, assess capabilities, and formulate a strategy to reduce disaster vulnerability.
Public participation and feedback is a vital part of the hazard mitigation planning process. The County developed a Hazard Mitigation Survey to inform the MJLHMP update. The survey asks questions about natural hazards and their impact on the community members of Riverside County.

Overview
The County of Riverside updated the Local Hazard Mitigation Plan (LHMP) as part of our efforts to reduce or eliminate long-term risks to our community. Some of these risks include earthquakes, pandemic flu, and wildland fires. This plan is required by the Disaster Mitigation Act of 2000 to be eligible for various federally funded grants and post-disaster assistance.
Purpose
The plan aims to reduce the impact of a disaster by identifying hazards and developing ways to decrease their impact. Risk assessments rate hazards with the greatest potential impact to the community. In addition, long-term prevention or protection steps are developed to lessen the impact of the hazard. This plan creates awareness of hazards, threats, and vulnerabilities within the community, and paves a path forward for jurisdictions to prepare for local disasters.
Scope
The LHMP Steering Committee gathers information and updates the plan using a whole community approach by engaging local jurisdictions, private sector organizations and community partners. The whole-community approach involves the entire community in disaster and hazard planning.
Objectives
Reduce loss of life and injuries.
Reduce hazard-related property losses
Protect the environment.
Coordinate disaster planning and integrate public policy.
Improve community and agency knowledge and education about hazards.
