Earthquake Site Conditions in the Wasatch Front Urban Corridor, Utah
We mapped and characterized Quaternary site conditions using shear-wave-velocity (Vs)-profile data for basins along the Wasatch Front urban corridor to provide a basis for estimating soil response during earthquake ground shaking. We map site conditions for each individual basin using surficial geologic mapping as a foundation, taking into account local conditions and subsurface information to delineate units using mean Vs for the upper 30 meters (Vs30) that we relate to International Building Code (IBC) site classes.

Programmatic Agreement Info
To comply with Section 106 of the National Historic Preservation Act, the Tonto National Forest developed a Programmatic Agreement (PA) and included it in Volume 5, Appendix O of the final EIS. The PA was created in cooperation with the Advisory Council on Historic Preservation, the State Historic Preservation Office, tribes and other consulting parties. The PA contains an agreed upon process for identifying, evaluating and addressing adverse effects to historic properties associated with this undertaking.
