Franklin did not grow significantly in the years following the American Civil War until the early twentieth century. In 1917, the town's boundaries were expanded, the streets were macadamized, and public water and electricity were brought into the town. However, tragedy struck on April 17, 1924 when a massive fire destroyed the entire business district and caused $500,000.00 (~$6.5 million adjusted for present inflation) in damages. Most of the town's center, its commercial district, and the Pendleton County Courthouse were constructed following the 1924 fire. Another disaster struck the town in 1985. The South Branch of the Potomac River in Franklin crested at 22.6 feet during the 1985 Election day floods. Flood stage at the time in the shallow riverbed was only 7 feet.
