He mapped close to 8,000 square miles between Washington and Baltimore, and watched changes since 1984. Sexton's maps show how development increased the intensity of the flooding by up to 30 percent, and Ellicott City is just one example. In the most recent storm, nearly 8 inches of rain fell in just three hours - intense water with nowhere to go. "We have flood maps that were drawn based on predictions that are no longer true," Sexton said.
Most were approved, according to county records. Developers submitted more than 100 plans to build residential and commercial buildings in about 3 square miles around Ellicott City.

Several tributaries above Main Street run through town to the river.
