Project Goals

Reduce flooding for residents, business, and farmers in the northwestern Grand Island, which floods regularly.

Update FEMA flood maps to reflect the flood risk reduction benefits work completed thus far, which will remove a portion of the properties currently in the floodplain.

Educate citizens on the residual risks associated with living near flood control structures.
