Hydraulic events result in thousands of incidents of property damage each year. The U. S. Army Corps of Engineers estimates that annual damage averages over $2 billion (CaE, 1991). Federal, state, and local agencies have set up emergency assistance programs to help pay these unusually heavy expenses. Despite the detail of the policies regulating such programs, a comprehensive database describing the causes and consequences of flood losses does not exist. In an effort to obtain clear and consistent statistics on highway related damage, the disaster files of the Federal Highway Administration's (FHWA) Emergency Relief (ER) Fund and the Federal Emergency Management Agency's (FEMA) Disaster Assistance Program (DAP) have been studied.
