Multi-Jurisdictional Hazard Mitigation Plan Update
Background
On Wednesday, April 23, 2025, the Walnut City Council awarded a Professional Services Agreement to Emergency Planning Consultants to update the City of Walnut’s Multi – Jurisdictional Hazard Mitigation Plan (“MJHMP”) for the 2025–2030 Planning period.
Why do we need to update the plan?
Updating the MJHMP is an essential step in maintaining the City’s eligibility for critical State and Federal funding before and after a major disaster. In compliance with Federal requirements, the City is required to revise and submit its MJHMP to the Federal Emergency Management Agency (“FEMA”) for review and approval every five (5) years.
What does the plan entail?
Building on the foundation of the current plan, the updated 2025–2030 MJHMP will re-examine key threats previously identified – earthquakes, landslides, and wildfires – and assess their potential impacts on the Walnut community. As part of this process, the Planning Team will also revise hazard and critical facility maps, which are instrumental in guiding effective mitigation strategies to reduce or eliminate risks.
Additionally, the update will also include a comprehensive review of the City’s capabilities, resources, and staffing levels to ensure the Plan reflects current conditions. This will serve as an update to the capability assessment conducted in the 2020 MJHMP.
Are there any other entities involved?
To support the joint development of the updated MJHMP, a Cooperative Funding Agreement (“CFA”) was also presented to the City Council in order to facilitate the joint preparation and development of the MJHMP in collaboration with the following agencies: the City of Walnut, Mount San Antonio Community College, and Walnut Valley Unified School District. The agreement outlines the roles and responsibilities of each participating agency in the development of the Plan, including the allocation of related costs.
