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 post-fire erosion efforts and brownfield redevelopment opportunities.
An industry leader in developing innovative approaches for the design and evaluation of stormwater infiltration facilities and redevelopment of closed landfills for beneficial uses, such as solar energy installations, Ron specializes in solid and hazardous waste disposal site permitting, design, and construction. He and his teams have designed and built facilities for the disposal of low-level radioactive, hazardous, and municipal solid waste across the Southwestern United States and abroad. Ron’s clients span a wide spectrum of industries, including transportation, water infrastructure, electrical power generation and distribution, high-rise construction, and mining. He also provides technical support to litigation cases, including testifying as an expert witness.
Ron's joint engineering expertise is invaluable in preparing solutions for geologically complex sites with landslide features, faulting, and challenging soil conditions. He has evaluated thousands of residential sites and commercial properties for impacts related to soil movement and moisture migration through concrete foundation and floor systems.
To advance the state of the practice for waste containment systems, Ron authors papers on geosynthetics and gives presentations to, among others, the National Academy of Sciences on the performance of engineered barriers. He is also instrumental in promoting infiltration awareness and advancing evaluation techniques to California-based geotechnical engineers. Ron is a member of the American Society of Civil Engineers and the Society of American Military Engineers.
