Flood Mitigation Program

Heavy rain can cause urban flooding, and can happen far away from our bodies of water. Flooding can happen when:

Each situation can be different, and depends on a number of factors. Flood mitigation looks for the causes of flooding in specific areas, using modeling software to determine how to reduce or eliminate the possibility of flooding.

In the past, flood mitigation projects have used these strategies to help prevent flooding:

Hydrologic & Hydraulic Modeling

Computer modeling has been completed on approximately 75% of the city. These models can further identify flood areas and determine where our future flood mitigation efforts should be. We also receive flooding complaints that help to identify areas prone to flooding. All of these efforts have resulted in increased inspection and maintenance of these areas.

Southwest Harriet Flood Mitigation Study

The Southwest Harriet area in Minneapolis has had a history of flooding challenges during large rainfall events. Computer models showed many structures, streets and parks could be subject to future flooding due to lack of capacity in the storm sewer system. A flood mitigation feasibility study was completed to address these issues.
