On November 29, MSD tested a portion of the Louisville Metro Flood Protection System as a preventative measure that is required by the U.S. Army Corps of Engineers. The floodwall closure near Slugger Field extends along an entire city block of Main Street, from Jackson Street to the entrance of the Slugger Field parking lot.

Most of the homes in the Maple Street Flood Mitigation Project area were built—early in the 1900s—where a stream once existed. The project area is situated in a highly urbanized, heavily impervious setting, which has repeatedly experienced serious flooding during heavy rainstorms.
