I feel deeply for the people of Ellicott City who got hammered by the flood. We, including government, should do everything possible to make those who suffered losses whole again. IMHO, the government should condemn the property along Main Street, purchase it from the owners, and return it to it's natural state (natural drainageway), extending to the flood zone limits. No construction of any kind should be ever permitted again within the limits of the flood zone.
