Army Corps and Metro Water present updated Cumberland River flood analysis: 100‑year elevations rise in downtown; East Bank filling shows minimal downstream run
Summary
The U.S. Army Corps of Engineers and Metro Water Services told the East Bank Development Authority that updated flood modeling shows the 100‑year base flood elevation in downtown Nashville is roughly 1–2 feet higher under the new analysis, and recommended raising key road and property grades in the East Bank.
The U.S. Army Corps of Engineers (Corps) and Metro Water Services briefed the East Bank Development Authority on updated flood modeling for the Cumberland River and the East Bank study area, reporting modest increases in base flood elevations downtown and offering design guidance for resilient development.
Tom Falco (assistant director, Metro Water Services) reviewed the city’s obligations under the National Flood Insurance Program and noted Metro has adopted local freeboard standards — four feet for residential structures and one foot for nonresidential buildings — above mapped base flood elevations. He said Metro will use the study’s best available data for permitting and regulation ahead of formal FEMA map adoption.
