Flood Mitigation Program

Urban flooding can happen far from water bodies. Usually this happens because of heavy rain. Urban flooding happens when storm drain systems are too small, there are too few storm drains, there is not enough green space to allow the stormwater to naturally soak into the ground. Each situation is different depending on where it happens. Flood mitigation work looks for the causes of flooding in specific areas, and uses computer software to figure out how to reduce or get rid of that flooding.

The City has completed many flood mitigation projects in the past, This includes adding new storm pipes, building stormwater holding ponds, adding more storm drain inlets so the streets can drain more quickly, and constructing green infrastructure projects like rain gardens. The City has also increased inspecting and maintaining our storm drain inlets and pipes in areas that have flooded in the past.

Until recently, the City primarily used flooding complaints to identify problem areas. However, these complaints were only part of the big picture of where flooding might happen. In 2014, the City of Minneapolis started creating computer software models to predict where flooding might occur. This software helps City staff plan and prioritize future flood mitigation projects.
