With these risks and vulnerabilities identified, local officials can reduce losses of life, injuries, and to limit future damages by developing methods to mitigate or eliminate damages. Scope The Columbiana County Hazard Mitigation Plan follows a planning methodology that includes public involvement, a risk assessment for various identified hazards, an inventory of critical facilities and at-risk areas, a mitigation strategy for high-risk hazards, and a method to maintain and update the plan. Plan Authority The Columbiana County Hazard Mitigation Plan is “multi-jurisdictional,” meaning that it includes several jurisdictions. Columbiana County stakeholders prepared this plan per federal requirements outlined in the Disaster Mitigation Act of 2000 (DMA2K), which requires communities to formulate a hazard mitigation plan to be eligible for mitigation funds made available through the Federal Emergency Management Agency (FEMA). Section 322 of the Robert T. Stafford Act requires that local jurisdictions develop and submit plans meeting the criteria outlined in 44 CFR Parts 201.6. When the content of this plan corresponds to a requirement of 44 CFR 201.6, it will include a description of the relevant guidance. The following table lists the requirements of 44 CFR 201.6 and identifies the sections of the plan fulfilling the guidance. 44 CFR 201.6 REQUIREMENTS IN THIS PLAN Section Description Section in Plan § 201.6 Local Mitigation Plans. The local mitigation plan is the representation of Section 1.0 Introduction the jurisdiction's commitment to reduce risks from natural hazards, serving as a guide for decision makers as they commit resources to reducing the effects of natural hazards. Local plans will also serve as the basis for the state to provide technical assistance and to prioritize project funding. § 201.6(a)(4) Multi-jurisdictional plans may be accepted, as appropriate, as long as Section 1.1 The Planning Process each jurisdiction has participated in the process and has officially adopted the plan. 1 Columbiana County Hazard Mitigation Plan 1.0 Introduction 44 CFR 201.6 REQUIREMENTS IN THIS PLAN Section Description Section in Plan § 201.6(b)(1) An opportunity for the public to comment on the plan during the drafting Section 1.1 The Planning Process stage and prior to plan approval Section 4.3 Continued Public Involvement § 201.6(b)(2) An opportunity for neighboring communities, local and regional agencies Section 1.1 The Planning Process involved in hazard mitigation activities, and agencies that have the authority to regulate development, as well as businesses, academia and other private and non-profit interests to be involved in the planning process § 201.6(b)(3) Review and incorporate, if appropriate, existing plans, studies, reports, Section 1.3 Capabilities and technical information Section 1.4 Trends & Predictions Section 4.2 Implementation through Existing Programs § 201.6(c)(1) Documentation of the planning process used to develop the plan, Section 1.1 The Planning Process including how it was prepared, who was involved in the process, and how the public was involved § 201.6(c)(2) A risk assessment that provides the factual basis for activities proposed Section 2.0 Risk Assessment in the strategy to reduce losses from identified hazards.
