Floodplain/Stormwater Management

Abstract

Situated on the Delmarva Peninsula between the Delaware Bay and Chesapeake Bay, Delaware is the lowest state in the United States, with a mean elevation of just 60 feet above sea level. Vulnerable to flooding from rising sea levels and ocean-fueled tropical storm systems, coastal Delaware is one of only three states located on a peninsula. Delaware floods originate along the hilly, rocky Piedmont streams in northern New Castle County and from the tidal bay and Atlantic Ocean.
