Ellicott City, Baltimore region devastated by 'once-every-1,000-years flood'
Maryland Gov. Larry Hogan late Sunday night declared a state of emergency in Ellicott City after a massive rainstorm caused flash flooding that destroyed businesses and submerged cars in what he called a “once-every-1,000-years flood.”
News outlets showed photos and video of sudden, violent floodwaters surging down Main Street in Ellicott City, some 13 miles west of Baltimore. The community, set along the west bank of Maryland's Patapsco River, was also stricken by deadly flash flooding in July 2016.
