City Council invests in flood mitigation with ConSpan bridge and property buyouts

Flood Mitigation Takes Center Stage at Norman City Council Meeting

During the City Council Study Session on June 3, 2025, flood mitigation strategies were a key focus, highlighting innovative approaches to managing water flow and reducing flood risks in Norman, Oklahoma.

City officials discussed the use of a proprietary bridge structure known as ConSpan, which allows for increased water flow during heavy rain events. This design has proven effective, with no flooding reported at the location, even during significant storms. However, officials acknowledged that minor overtopping could occur in extreme conditions, emphasizing the need for continued evaluation of flood management solutions.

The meeting also spotlighted the city’s successful program for purchasing homes that have experienced repetitive flooding. One notable example was a property at 218 South Oklahoma, which had routinely flooded, with water levels reaching above door thresholds. The city acquired the property at a reduced price due to prior insurance claims, and it has since been deed-restricted to prevent future construction. This initiative not only eliminates the risk of flooding for that site but also allows for the development of a rain garden to enhance water absorption and storage.

City leaders expressed optimism about these strategies, noting their potential to improve community resilience against flooding while also enhancing local green spaces. As the city continues to explore innovative designs and programs, residents can expect ongoing efforts to safeguard against future flood risks.
