Activities and Initiatives Crawford County, MO Multi-Hazard Mitigation Plan EXECUTIVE SUMMARY The purpose of natural hazards mitigation is to reduce or eliminate long-term risk to people and property from natural hazards. Washington County and participating jurisdictions developed this multi-hazard mitigation plan to reduce future losses to the County and its communities resulting from natural hazards. The plan was prepared pursuant to the requirements of the Disaster Mitigation Act of 2000 and to achieve eligibility for the Federal Emergency Management Agency (FEMA) Flood Mitigation Assistance, Pre-Disaster Mitigation and Hazard Mitigation Grant Programs. The Washington County Multi-Hazard Mitigation Plan is a multi-jurisdictional plan that covers the following local governments and organizations that participated in the planning process: Washington County Village of Caledonia City of Irondale Village of Mineral Point City of Potosi Kingston K-14 School District Potosi R-III School District Valley R-VI School District Richwoods R-VII School District The County’s planning process followed a methodology prescribed by FEMA, which began with the formation of a Hazard Mitigation Planning Committee (HMPC) comprised of key stakeholders from Washington County, participating jurisdictions and state and federal agencies. The Washington County HMPC was assisted in this planning effort by the Meramec Regional Planning Commission (MRPC). The MRPC was created January 23, 1969 by then Governor Warren E. Hearnes. The commission serves the eight-county area of Washington, Dent, Washington, Maries, Osage, Washington, Pulaski and Washington counties as well as 33 municipalities. Under the initiative set forth by the Missouri State Emergency Management Agency (SEMA), the Missouri Association of Councils of Government (MACOG) agreed to meet the challenge of developing plans for cities and counties throughout the state. SEMA’s initiative further states that due to time and funding limitations, the plans developed by Missouri’s regional planning commissions should cover natural hazards only. Manmade and/or technological hazards are not addressed in this plan, except in the context of cascading damages. The MRPC assisted the Washington County HMPC by providing professional staff to coordinate the committee’s activities and prepare the planning document. MRPC staff took the input provided by the HMPC and incorporated it into the plan document. Citizens and public organizations have participated in the process. This effort will be sustainable over the long term because it enjoys grassroots
