Ellicott City and the neighboring community of Catonsville anchor this mid-century survey of the Howard and Baltimore County border. The winding Patapsco River serves as the central geographic feature, flanked by the steep hillsides of Patapsco State Park. Transportation networks define the area's development, from the historic National Pike and Frederick Road to the heavy-duty infrastructure of the Baltimore and Ohio railroad which follows the river’s curves.
