Representative highlights of Willdan Geotechnical's recent water and sewer projects are presented below.
Client: Morongo Band of Mission Indians
Project: Above Ground Water Tank
The proposed above ground water tank for a new casino was located within a State of California Alquist-Priolo Fault Zone and County of Riverside Fault Hazard Zone for the San Gorgonio Pass Fault. The investigation included a 300-foot, 11-foot deep trench to identify potential faults. Recommendations were made about mitigation strategies as required. Seismic hazard analysis included development of a site-specific response spectra for the eastern terminus of San Bernardino Mountain segment of the San Andreas fault which is located less than ½ mile from the site. Recommendations for mitigating the potential for settlement up to 4 inches induced by the strong ground motion were provided in the report.
