“It seems,” the Baltimore Sun wrote in 2012, “that Ellicott City has come in for an inordinate amount of disasters from floods, fires and railroad wrecks since its founding in 1772.”

The unincorporated town of 68,000 has endured at least four major floods, according to the Maryland Historic District’s web site, including a pair in the 1970s, another in 1923 and one in 1868 that “wiped out most of early industry in the valley sparing only the flour mill.”
