FEMA/SEMA/MACOG PLANNING INITIATIVE As a result of new federal regulations imposed by the Federal Emergency Management Agency (FEMA), cities, counties, and organizations that were eligible for hazard mitigation grant funding in the past will no longer be eligible after November, 2004, unless they have adopted a Hazard Mitigation Plan. This ruling affects more than 1,000 cities and 114 counties in Missouri. Although these communities will still be eligible for federal disaster Public Assistance and Individual Assistance, they will not be eligible for mitigation assistance unless they have developed and adopted a plan. The State Emergency Management Agency (SEMA) was faced with the challenge of trying to provide assistance, support, and guidance to all of these cities and counties in their efforts to develop and adopt a Hazard Mitigation Plan. As a result, SEMA approached the Missouri Association of Councils of Government (MACOG) to request participation of the Regional Planning Commissions in the effort to develop these plans. SEMA and MACOG cooperated to develop a joint Mitigation Planning Initiative to develop mitigation plans for natural disasters only. This restriction was necessary due to the funding limitations of FEMA. While SEMA/MACOG developed this Mitigation Planning Initiative, the cities and counties received the funding to prepare the plans and contracted with Regional Planning Commissions to perform the work. SEMA provided training and technical assistance to the Regional Planning Commissions, but the funding will go to the participating cities and counties. All of the plans will be developed in accordance with a Scope of Work drawn up by SEMA. This method is being used to ensure that the local governments participate fully in the development of the Hazard Mitigation Plans that they adopt. It is felt that, if the local units of government do not participate in the development of the planning document, then they will not feel that they have any stake in following through with recommendations made in the plan. Perry County contracted with the Southeast Missouri Regional Planning Commission through the SEMA
