Utah Geologic Survey Special Study 127 Reports & Maps

In 2008 the Utah Geologic Survey published Special Study 127, Geologic Hazards and Adverse Construction Conditions. This study covered St. George - Hurricane Metro areas of Washington County at 1:24,000 scale mapping. Copies of this report, along with the GIS data, can be ordered on DVD directly from the UGS Bookstore.

The City of Hurricane Planning/Zoning Department will begin using this study as a guide when evaluating new developments that may require special conditions. To facilitate this policy the GIS Department has produced a series of the map at 1:24,000 scale maps that focus specifically on Hurricane. These maps are also a valuable resource for developers when searching for candidate areas within the city suitable for development.
