Flood Cleanup in Cincinnati, OH

Flood cleanup in Cincinnati encompasses the full spectrum from catastrophic Ohio River flooding — which can affect tens of thousands of properties in a multi-county event — to the localized but frequent hillside groundwater flooding that affects individual properties across the metro's distinctive steep-slope neighborhood geography. The Ohio River's flood frequency at Cincinnati is driven by the combined watershed of the Great Lakes drainage divide — including the Scioto, Great Miami, Licking, and Kentucky Rivers — that merge into the Ohio upstream of the city and create flood peaks that are among the highest in the nation's inland river system. The Metropolitan Sewer District of Greater Cincinnati (MSD) manages the combined and separate sewer systems that serve the metro, including the lower-elevation neighborhoods most vulnerable to flood contamination. A standard Cincinnati flood cleanup project after an Ohio River event involves Category 3 contamination protocols for the Ohio River bottomland neighborhoods of Riverside, Sayler Park, and the East End, where the river rises above the street level of these pre-flood-wall communities and deposits silt, oil, and sewage contaminants inside residential structures. Cincinnati's cast iron and stone building stock in the Ohio River corridor absorbs floodwater more deeply and retains it longer than modern wood-frame construction, requiring extended drying operations.
