Flood Risk Management<\/h2>\n

With 1\/3 of the City of Columbus planning jurisdiction located in a floodplain, flooding is the primary natural threat to the community.\u00a0 Remember don’t drive in flooded areas and obey all flood warning signals and road closings.\u00a0 The Columbus Flood Risk Management Plan is intended to address all aspects of that flood risk.\u00a0 The Plan assess the threat from local streams, provides the background information for the companion Flood Response & Evacuation Plan, evaluates opportunities to mitigate flooding risks for specific streets and neighborhoods, and identifies regulatory actions that could prevent the flood risk from becoming worse.<\/span><\/p>\n

The Columbus Flood Risk Management Plan was recognized with the 2013 Excellence in Floodplain Management award from the Indiana Association for Floodplain and Stormwater Management (INAFSM).<\/span><\/p>\n

The initial 2013 Plan was updated in 2020.\u00a0 The current Plan materials are provided below.<\/p>\n
