Ronald Johnson is a Senior Principal Geotechnical Engineer based in California who has been focused on the most seismically active areas of the United States throughout his career. He has led dozens of multidisciplinary teams as they tackled a wide range of challenging and multi-faceted engineering projects, including electrical transmission and distribution, post-fire erosion efforts and brownfield redevelopment opportunities.


As an industry leader and consultant, Ron specializes in applying geotechnical, geoenvironmental, and civil engineering principles to the development of infrastructure and the constructed environment.

Ron has led large multidisciplinary civil projects involving design teams with more than 100 personnel, and he has managed several multi-year engineering contracts with public agencies. His infrastructure experience spans a wide range of industries including water infrastructure, electrical power generation and distribution, brownfield remediation, and mining.  Specific to the electrical power industry Ron's experience includes geotechnical investigations and design for substations, large kV underground and overhead transmission, and review of lattice tower and monopole foundation systems. He has also served as the Project Director for wood-to-steel pole and reconductoring projects, drainage assessments, and developing sustainable solutions for erosion and sediment control for electrical power projects.

His joint geological and geotechnical engineering expertise proves invaluable in preparing solutions in geologically complex sites such as those with landslides, faulting, and challenging soil conditions. Advancing the practice, Ron has authored technical papers on geosynthetics and gives presentations to, among others, the National Academy of Sciences on the performance of engineered barriers.
