The picturesque Main Street of Ellicott City , Maryland, faces a months-long recovery that could cost hundreds of millions of dollars after devastating flooding that damaged nearly every home and business along the road, officials said. Two people were killed when the town about 14 miles west of Baltimore took on 6.5 inches of water Saturday night, most of it between 7 p.m. and 9 p.m., sweeping away hundreds of cars, tearing away sidewalks and wrecking storefronts and building foundations.
