City of Cathedral City
Cathedral City, California
Earth Systems provided review of geotechnical engineering reports to verify compliance with Cathedral City guidelines and the accepted professional standard of care, and to update geotechnical criteria to conform to current California Building Code requirements. Supplemental geotechnical recommendations were also developed. The project was a stage structure for a proposed amphitheater, which was to be constructed at the intersection of Cathedral Canyon Drive and Avenida Lalo Guerrero in Cathedral City.
Challenges at the site included the potential for seismically induced settlement and the presence of shallow electrical lines that crossed within the stage foundation area. Supplemental recommendations presented options for site grading in foundation areas to allow flexibility for the client to select the most cost-effective approach based upon available budget and project objectives.
Geotechnical criteria were also developed for excavation, utility trenches, and foundations. During construction, Earth Systems provided geotechnical observation and materials testing.
