The Amargosa Creek Detention Facility is a 130,000 cubic yard earth fill dam, constructed to provide storm water detention facilities along Amargosa Creek. A reinforced box culvert extends through the dam. The California Division of Safety of Dams was the governing authority for this project.

Earth Systems performed the preliminary geologic and geotechnical studies relative to the siting and design of the dam within the San Andreas Fault Zone. Our studies addressed issues such as active fault locations, slope stability of abutments and spillways, suitability of borrow-area soils for embankment fill construction, and suitability of bedrock foundations. During construction, we provided extensive materials testing and inspection.
