7.6.1 Priority Levels

x Low-Priority Mitigation Actions: address lower-risk concerns or long-term objectives and can be deferred without immediate impact to safety or core functions.

7.6.2 Changes in Criteria
The 2014 Los Angeles County AHMP’s Mitigation Action Matrix was prioritized using pUN1aJVA]‘3NJU_VJA]‘L^V_VmplApVvN‘-a]VpVJA]‘!NTA]‘_vVla _^N_pA]‘A_LJa_a^VJ Ÿ13-! ^NpUaL‘wUVJU"UALlNJa^^N_LNLAmAilValVpV|ApVa_ilaJNLqlNV_pUN early to mid-2000s. The 2020 AHMP replaced the use of STAPLEE with a more streamlined prioritization process that included the following:
x 3alN^NLyalilNvN_pA^A[alUNA]pUmASNpyUA|AlL‘A^VpVTApVa_ ila[NJp^qmp have political support.
x 3aIqV]LAJq]pqlNA_LilAJpVJNaSLVmAmpNllNmV]VN_JN‘A^VpVT ApVa_ila[NJp^qmp have social support.

This prioritization method used in the 2020 AHMP has been adapted and incorporated into the prioritization criteria described previously in Section 7.6.

7.7 Integration with Other Plans
The County of Los Angeles ensures that mitigation is a countywide effort with multiple departments contributing to critical activities that reduce hazard risks. These actions are captured in other discipline-miNJVœJi]A_mV_ALLVpVa_papUN"-‘V_J]qLV_TpUamN listed in Table 7-9.

This portal will serve as a mechanism to obtain continuous public feedback as projects are implemented and offers access to mitigation resources.
x Standing Advisory Committee: The Hazard Mitigation Advisory Committee will be expanded to a standing status and will meet at least once per year or more often as determined necessary to support hazard mitigation projects. The standing Hazard Mitigation Advisory Committee will be comprised of representatives from diverse community groups to provide ongoing input and oversight of hazard mitigation efforts. The standing Hazard Mitigation Advisory Committee will also serve as an important forum for future updates of the AHMP .

These activities ensure that the community remains informed and actively engaged in the plan’s implementation and maintenance.

All-Hazards Mitigation Plan

9.1 Plan Adoption Overview
Plan Adoption addressed Element F of the Local Mitigation Plan Regulation Checklist under single jurisdiction plan requirement.

The Los Angeles County Board of Supervisors of œcially adopted the 2025 All Hazard Mitigation Plan (AHMP) through a formal resolution on September 9, 2025. A scanned copy of the resolution is included in Appendix F. The Los Angeles County Of œce of Emergency Management (OEM) will retain the resolution for its records, while copies will be submitted to both Cal OES and FEMA.

This Plan adoption completes the mitigation planning process and department agencies, stakeholders, and community’s commitment to the goals and actions. It also recognizes the current planning process and acknowledges changes from the past œve years and validates the priorities for hazard mitigation actions. It makes the community eligible for certain FEMA assistance that can fund some mitigation actions.

After being adopted by the Los Angeles County Board of Supervisors, the 2025 AHMP transitions into the implementation phase. The success of the plan hinges on the integrating its mitigation strategies and actions into the local plans and policies. The mitigation action items collectively establish a robust framework to guide the County’s hazard mitigation strategies over the next œve years. To ensure these strategies are effective, actionable and well aligned with the county’s long term resilience goals, the Planning Advisory Committee has set clear objectives. Their prioritized approach focuses on seamlessly blending mitigation actions with current policies, plans, and emphasizing collaboration and coherence throughout.
