Will dredging of the flood control channel reduce flood risk?

Based on the 2020 LFHA report, dredging the flood control channel provides some protection from flooding adjacent to the channel, and reduces the depth of flooding in other low lying areas.  However, a large portion of the flooding shown in the new FEMA maps comes from high streamflow overtopping the banks in Six Mile, Cascadilla, and Fall Creeks.    

The dredging project will be performed by the NYS Department of Environmental Conservation (DEC) and is an important component of the City’s flood control program.  The City is supporting the DEC in this effort, but has no control over the project schedule and budget.
