From the User Guide Overview:

Hazus® is a geographic information system (GIS)-based tool and set of methods for loss estimation from natural hazards. Hazus is developed and supported by the Federal Emergency Management Agency (FEMA). The Oregon Department of Geology and Mineral Industries (DOGAMI) ArcGIS® Python® Script Alternative (hereafter, “script”) is intended to complement a structure-level Hazus analysis of flood risk by providing rapid estimates of damage to building, content, and inventory, building debris, and building repair/replacement times, for a given flood depth grid or set of flood depth grids. Users may specify particular depth-damage functions (DDF) for a particular user-defined facility (UDF), or let the script choose the standard (default) DDF. With the rapid turnaround, users can more quickly evaluate their UDF parameters for accuracy and pursue in-depth sensitivity analyses. The script is targeted for users who have developed flood depth grids outside of the Hazus-MH flood model, especially for users with high-resolution flood depth grid(s) derived from lidar-based digital elevation models.
