United States Public Law 106-390, October 30, 2000: Disaster Mitigation Act of 2000 Provides a source of federal pre-disaster hazard mitigation funding. The funds can used to support effective public-private natural disaster hazard mitigation partnerships; to improve the assessment of a community s vulnerability to hazards; or to establish hazard mitigation priorities, and an appropriate hazard mitigation plan, for a community. A portion of the funds can also be used for public information dissemination. Local governments must submit a hazard mitigation plan to be eligible for the funds. The law also provides for federal multi-hazard advisory maps in some states. Recent
