The Department of Homeland Security's Federal Emergency Management Agency (FEMA) has developed a series of "how-to" guides for the purpose of assisting Tribes, States, and local governments in developing effective hazard mitigation planning processes. The material presented in these guides is intended to address the needs of both large and small communities with varying degrees of technical expertise and financial resources. The topic area for this guide is "Multi-Jurisdictional Approaches to Hazard Mitigation Planning" (FEMA 386-8). This guide provides suggestions to local governments in preparing multi-jurisdictional hazard mitigation plans that meet the DMA 2000 planning requirements. Other guides that have been developed by FEMA as part of the "how-to" series include: Getting started with the mitigation planning process, including important considerations for how you can organize your efforts to develop an effective mitigation plan (FEMA 386-1); Identifying hazards and assessing losses to your community, State, or Tribe (FEMA 386-2); Setting mitigation priorities and goals for your community, State, or Tribe and writing the plan (FEMA 386-3); Implementing the mitigation plan, including project funding and maintaining a dynamic plan that changes to meet new developments (FEMA 386-4); Evaluating potential mitigation actions through the use of benefit-cost review (FEMA 386-5) (to be published); Incorporating special considerations into hazard mitigation planning for historic properties and cultural resources, the topic of this how-to guide (FEMA 386-6); Incorporating mitigation considerations for manmade hazards into hazard mitigation planning (FEMA 386-7); and Finding and securing technical and financial resources for mitigation planning (FEMA 386-9). The first four guides are commonly referred to as the "core four" as they provide a broad overview of the core elements associated with hazard mitigation planning. This and the other guides are supplementary "how-to" guides that are to be used in conjunction with the "core four." Disaster Mitigation Act of 2000 (DMA 2000) DMA 2000 provides an opportunity for States, Tribal Governments, and local jurisdictions to significantly reduce their vulnerability to natural hazards. It also allows them to streamline their access to and use of Federal disaster assistance, through pre-disaster hazard mitigation planning. DMA 2000 places new emphasis on State, Tribal, and local mitigation planning by requiring these entities to develop and submit mitigation plans as a condition of receiving various types of pre- and post-disaster assistance (such as the Pre-Disaster Mitigation Program [PDM] and the Hazard Mitigation Grant Program [HMGP]) under the Stafford Act. On February 26, 2002, FEMA published under Title 44 Part 201 of the Code of Federal Regulations (CFR) an Interim Rule (the Rule) to implement the mitigation planning requirements of DMA 2000. The Rule outlines the requirements for both State and local mitigation plans. FEMA has prepared a document, Multi-Hazard Mitigation Planning Guidance under the Disaster Mitigation Act of 2000, that explains the requirements of the Rule with the help of sample plan excerpts and discussion.
