The City of Desert Hot Springs, Desert Hot Springs, California
Earth Systems performed a limited geotechnical study to address geotechnical recommendations for the reconstruction of the roadway in response to road damage created by Tropical Storm Hilary in 2023. The storm caused partial roadway washout and closed traffic through the Mission Creek crossing at Dillon Road in Desert Hot Springs, California. The Palm Springs area normally obtains 0.18 inches of rain for August, but Tropical Storm Hilary brought almost 4 inches of rain to the lower areas of the city of Palm Springs area and even more in the higher mountain’s tributary to Palm Springs and Desert Hot Springs area.
Earth Systems performed a site visit and observed and collected data from the damaged area. Engineering analyses were performed on the data obtained and recommendations for design parameters were presented for earthwork and pavement sections for roadway repairs in a limited geotechnical engineering report.
During emergency repair of the roadway (under Federal Funding), Earth Systems performed the grading observation and compaction testing, as well as concrete sampling for slope armoring, culverts and cutoff walls.
