Minnesota State Hazard Mitigation Plan 2019 - Including Recommended Actions for Climate Change Adaptation
Minnesota’s 2019 State All-Hazard Mitigation Plan (HMP) includes recommended actions for climate adaptation for the first time in the state’s hazard mitigation planning process. Developed in collaboration with the Interagency Climate Adaptation Team (ICAT), the HMP includes priority adaptation needs for state government from the ICAT 2017 Report - Adapting to Climate Change in Minnesota. The HMP provides assessments of hazard risk, reviews current state and local hazard mitigation and climate adaptation capacity and programs, and includes climate adaptation strategies for Minnesota’s state agencies and programs.
Minnesota developed this plan to address the current impacts of natural and man-made hazards as projected over the next 5 years (2019 -2024), and offers tactical resilience strategies that can be integrated into new and existing hazard planning and projects. The current and anticipated role of climate change is analyzed for each focal hazard including: flooding, wildfire, windstorms, tornadoes, hail, lightning, coastal erosion, winter storms, land subsidence, drought, extreme cold, extreme heat, earthquakes, dam/levee failure, erosion/landslides/mudslides, and ground and surface water supply.
The report provides detailed accounts of hazards and their climate correlated occurrence across the state. For example, Extreme Heat has been Minnesota’s "third deadliest weather factor since 1990" - and there were 54 heat-related deaths in the state from 2000 - 2016. A number of extreme heat events from recent years are described.
Flooding is the number one natural hazard to impact Minnesota - accounting for the most federal disaster declarations of any hazard. Climate change brings heavier and more intense rains than at any time on record, and “long-term observation sites have seen dramatic increases in 1-inch rains, 3-inch rains, and the size of the heaviest rainfall of the year. Since 2000, Minnesota has seen a significant uptick in devastating, large-area extreme rainstorms as well.”
Extreme Cold in Minnesota can have severe or fatal impacts, and wind chill factors can increase the risk of frostbite or hypothermia. Winter Storms continue to be a hazard with high probability and low mitigation potential that affect the entire state including transportation systems, electrical distribution systems, infrastructure, public health and vulnerable communities. High energy use, reduced reliability of services, outages, and potential rise in household energy costs are major climate change risks to public health that are expected from extreme winter weather.
Section 5: Hazard Mitigation and Climate Adaptation Strategy includes ICAT’s six adaptation recommendations for the state, along with related goals and strategies formulated to support the implementation of these recommendations:
1. Build greater resilience to extreme precipitation
2. Identify opportunities to strengthen the climate resilience and health of vulnerable populations of Minnesotans across state agency programs and through cooperation with local governments
3. Increase focus on preserving natural and restored terrestrial and aquatic ecosystems and habitat to increase resilience of wildlife and native plants
4. Strengthen agricultural water management efforts to increase resilience to climate change impacts
5. Increase focus on managing climate impacts in cities, towns, and other population centers
6. Strengthen our climate information infrastructure to support climate adaptation practices
Section 5.5 - Funding and Project Implementation provides information on resources available to assist local jurisdictions with hazard mitigation planning and implementation. Examples of successful projects and funding allocation are included.
The Minnesota Department of Public Safety, Division of Homeland Security and Emergency Management (HSEM) is responsible for ensuring the state has a FEMA approved All-Hazard Mitigation Plan - that is required to be updated every five years. HSEM contracted with the University of Minnesota - Duluth Geospatial Analysis Center to update the state profile, natural hazard risk assessment, vulnerability assessments and more, including hazard mapping. This plan was also updated working with subject matter experts, the Interagency Climate Adaptation Team, and a federal collaborative risk management group, the Silver Jackets.
