What is the St. Louis Regional Hazard Mitigation Plan?

1993 Flood

The St. Louis Regional Hazard Mitigation Plan is designed to help protect public safety and prevent loss of life or injury in the event of a natural disaster by providing recommendations for advanced preparation for first responders, local government leaders, and school personnel. By planning for disasters in advance, emergency response personnel and local governments are able to increase their operational effectiveness, reduce costs, save lives, and improve the efficiency of disaster response and recovery. It also reduces the risk to existing and future development and to prevent damage to each community’s unique economic, cultural, and environmental assets.

The recommendations contained in the St. Louis Regional Hazard Mitigation plan are guidelines for voluntary action. Local jurisdictions adopt the plan, then identify priorities and carry out those elements of the plan that best serve local community needs and challenges.

St. Louis Regional Hazard Mitigation Maps

As part of the plan development process, EWG staff created maps that depict selected natural hazards for each of the jurisdictions covered by the St. Louis Regional Hazard Mitigation Plan. EWG’s Library contains all of the St. Louis Regional Hazard Mitigation Maps. Use the links below to find maps for a specific jurisdiction.

Plan Development and History

Originally developed in 2004 with funding from Missouri’s State Emergency Management Agency (SEMA), the St. Louis Regional Hazard Mitigation Plan is reviewed and revised every five years with the current plan updated for 2015-2020. The plan covers the Missouri portion of the St. Louis region, which includes the city of St. Louis, Franklin, Jefferson, St. Charles and St. Louis counties, 135 municipalities, and 50 school districts. The latest version of the plan has been significantly revised to reflect both changing conditions and local efforts to focus on regional collaboration. Planning partners included the St. Louis Area Regional Response System (STARRS), county emergency managers, municipal league representatives, the St. Louis Area Regional Coalition of Community Organizations Active in Disaster (SLARCC), and EducationPlus. Plans in Illinois are prepared by each county. East-West Gateway Council of Governments (EWG) prepared the plan in accordance with guidelines established by the Federal Emergency Management Agency (FEMA) and SEMA. These agencies have authority for the final review and approval of the plan. EWG submitted the draft plan to SEMA and FEMA in December 2014, and a final draft plan was submitted on March 31, 2015.  Staff responded to FEMA’s comments, and after two rounds of reviews, EWG submitted the final plan on June 1, 2015.  FEMA has now approved the plan. FEMA sent an approval letter to EWG on July 13, 2015.

Plan Adoption for Municipalities

Current rules require that local governments and school districts applying for federal pre-natural disaster mitigation funding must have a FEMA approved plan. Any community or school district seeking pre-natural disaster mitigation funding must formally adopt the plan by resolution in order to be eligible for FEMA/SEMA funding.

Governing bodies of counties, municipalities, and schools districts can use this model adoption resolution prepared by EWG staff when adopting the final plan. The final plan has been sent to clerks, emergency management agencies, and school districts. Plan adoption by Missouri communities and school districts will be on a voluntary basis. EWG staff encourage jurisdictions to adopt the plan.
