Abstract

Analysis of Economic Losses in Fargo using HAZUS
Track: Disaster Management and Emergency Response
Authors: Jesse Rozelle

During the historic Red River flooding of 2009 and 2010 in the Fargo region it became a priority
to develop a site specific structure dataset for use in FEMA's HAZUS (Hazards U.S.) flood model. With this structure dataset, we were able to assess the impacts to Fargo from various flooding event scenarios. ArcGIS water depth grids were created by Houston Engineering and the International Water Institue using flood control measure data, hydrologic modeling, river crest heights, and LiDAR. The depth at each structure was then used to calculate losses using depth damage curves and assessor derived building attributes. The results from this analysis allowed FEMA to measure the dollar losses avoided by FEMA Region VIII mitigation programs, as well as an estimate on the financial impact the floods had on the citizens of Fargo.
