Dealing with Flooding in Minnesota

Minnesota's geographical location undoubtedly contributes to its exposure to a variety of severe weather conditions, including heavy rain, thunderstorms, tornadoes, and winter blizzards. These storms can bring heavy rainfall, like we saw in June of 2024 which contributed to the area floods.

Managing stormwater in Minnesota is a significant challenge. The state’s large expanses of impermeable surfaces in urban areas prevent proper absorption of rainwater, leading to runoff that exacerbates flooding. Additionally, Minnesota's soil, particularly in regions with high clay content, has low permeability, which does not allow water to seep into the ground quickly, thereby increasing surface runoff and flooding.

The flooding event in June 2024 was triggered by unprecedented heavy rain, causing the Minnesota River, which flows through the city, to swell to record levels. The city faced sewer back-ups, bridges and dams, such as the Rapidan Dam, were compromised. The flooding was not limited to Mankato; nearby cities like Waterville also faced significant flood damage.

The 2024 flood in Mankato highlighted the city's responsiveness.  Over the years, Mankato has focused on strengthening its levees and enhancing its storm water management systems which seemed to help against further spread of flooding and damage as well as a quick recovery.  Small businesses like SERVPRO of Mankato/ Owatonna, which services those cities and surrounding areas, was prepared to help businesses and homeowners get their property cleaned up.

During the time of the flooding, SERVPRO of Mankato/ Owatonna saw many basements that flooded due to sump pump failure or couldn't keep up with the rain, foundations that failed and seeped water, egress windows that pooled water, and drainage systems that were overwhelmed.  The SERVPRO® team is certified WRT, IICRC, and Mold Removal and Remediation which ensures process is followed.

The frequency and intensity of storms in Minnesota necessitate robust preparedness and response strategies. Communities, especially those like Mankato located near major waterways, must prioritize flood mitigation efforts. These can include constructing levees, installing sump pumps in homes, and designing buildings and infrastructure that can withstand flood conditions.

Storm damage and flooding remain significant concerns for Minnesota. Events like the June 2024 flood in Mankato and Southern Minnesota underscore the need for continuous improvement in how these challenges are managed. Through community resilience, improved infrastructure, and strategic planning, Minnesota can hope to mitigate the impacts of severe weather and protect properties from future storms and floods.
