Maryland's Flood Vulnerability Assessment

In order to provide a systematic examination of the vulnerability of Maryland’s built environment to riverine and coastal flooding, the Eastern Shore Regional GIS Cooperative (ESRGC) at Salisbury University was asked to undertake a vulnerability modeling effort. Using FEMA’s HAZUS-MH hazard vulnerability analysis modeling software, the ESRGC sought to generate maps and tables of Maryland’s potential for loss related to buildings from flooding on a county-by-county basis. This potential for loss, or the degree of vulnerability, was measured using four different factors: amount of county land area in susceptible to a 100-year flood, the amount of square footage of buildings potentially damaged, the number of buildings potential damaged, and the amount of direct economic losses related to buildings. These four measures of loss help give a more complete picture of the very complex issue of vulnerability to floods.

On this page you will find the complete HAZUS Flood Vulnerability Report, as well as the actual HAZUS Run files used in the project. The Report is in Adobe PDF format and consist of three seperate parts. The HAZUS Runs require the user to have FEMA's HAZUS-MH Version 1.1 in combination with ESRI's ArcMap Version 9.0.1 or newer. HAZUS-MH 1.1 can be requested directly from FEMA here at no cost.
