Why is it Important?

The effects of hazards such as tornadoes, floods, and severe winter weather can be reduced through hazard mitigation efforts, which are any actions that reduce or eliminate long-term risk to people and property. Hazard mitigation plans address hazards that have the potential to affect an area and identify strategies to reduce those threats. In Missouri and Illinois jurisdictions work together to produce multi-jurisdictional hazard mitigation plans. Since 2004 federal law has required local hazard mitigation plans in order for local governments to be eligible for hazard mitigation grant funding through FEMA. Each hazard mitigation plan lasts for five years, after which a new plan must be completed to ensure that plans are relevant and up to date.

How are we Doing?

In the St. Louis region the percent of local governments (cities and counties) participating in a local hazard mitigation plan decreased from 84.3 percent in 2010 to 52.7 percent in 2017. As of 2015, there is a plan in place for all jurisdictions in the St. Louis region. However, jurisdictions formally pass an adoption resolution to participate in a new plan, which is updated every five years. The decrease in participation from 2010 to 2017 is partially due to some jurisdictions not adopting new plans that were finalized since 2010. Additionally, St. Clair County’s plan expired in 2015, but the county is currently finalizing details on a new plan.¬†
