LOMA and LOMR-F in Franklin County, Ohio
Franklin County is drained by the Scioto River, Olentangy River, and Big Walnut Creek, which converge in the Columbus metropolitan area. The Scioto River has a history of major flooding, and the city of Columbus has invested significantly in floodwall and levee systems to protect downtown. Flash flooding along Big Walnut Creek and Alum Creek remains a hazard during intense rainstorms, and urban development has increased stormwater runoff throughout the county.
