Chris Conkle is a Principal Geotechnical Engineer based in California with more than 17 years of experience focused on geotechnical investigation, evaluation, design and quality assurance monitoring for a variety of dam, water resources, and infrastructure projects.


Chris’ dam safety experience includes serving as the project manager and technical lead for Geosyntec’s Embankment Dam Stability Evaluation and On Call Dam Safety projects for Southern California Edison. He has facilitated sessions to develop potential failure modes (PFMs) and to assess likelihood and consequence related to geohazards for hydropower facilities. Chris also served as the geotechnical task leader for the evaluation of seismic design alternatives for remediation of a hazardous waste landfill at site in Southern California.

As the project manager for a recent multidisciplinary earthquake engineering planning study, Chris led the combined geotechnical and structural evaluations of 60 existing structures at OC San’s (Orange County Sanitation District) two Southern California plants. Taken together, these plants are the third largest wastewater treatment plant west of the Mississippi River. The study identified vulnerabilities, estimated planning-level budgetary costs to implement the retrofits, and prioritized the importance of implementing these measures.

His efforts managing the geotechnical evaluations and design related to several bridge and tunnel structures for Orange County’s Public Works’ largest construction contract were recognized when Roads and Bridges magazine selected this as the second most significant road project in North America in 2016.

To advance the state of the practice, Chris is an active member of United States Society on Dams (USSD) and the Association of Dam Safety Officials (ASDSO). He also participates in the Centre for Energy Advancement through Technological Innovation (CEATI) in support of his hydropower clients. He has published several peer-reviewed conference papers and presented at numerous industry conferences.
