Technical Basis for Revision of Regulatory Guidance on Design Ground Motions: Development of Hazard- and Risk-consistent Seismic Spectra for Two Sites
We develop recommendations for design spectra at two sites, one in the Mojave desert, California, and the second at Columbia, South Carolina. These sites were chosen because local, small earthquakes dominate the high frequencies (f⩾10 Hz), but large distant events dominate the low frequencies (f⩽1 Hz). Both rock and soil conditions are examined at each site.

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.
