Background

About Ken Fergason

Mr. Fergason has been with the City of Flagstaff since 2020 and is a Registered Professional Geologist in Arizona and California. He is a Project Manager at the Cinder Lake Landfill. Previously Ken was an engineering geologist with an engineering design firm where he was utilized as a project manager, technical lead, project geologist, task manager, and field geologist performing geologic, geotechnical and geologic hazard investigations for dams, levees, channels, basins, buildings, roadways, bridges, power plants, transmission lines, mining projects, pipelines, and other structures. In addition, he has been extensively involved in the characterization of land subsidence and subsidence-related hazards such as earth fissures and associated impacts for planning, design, remediation, and long-term monitoring. Mr. Fergason has experience investigating additional geologic hazards including landslides and seismic hazards and has received specialized training in the use of LiDAR and high resolution DEMs for landslides and slope stability. Mr. Fergason has also been involved in projects that utilize remote sensing technologies such as InSAR as they apply to geologic and geotechnical characterization, including ground subsidence and earth fissuring and slope stability issues. He has also utilized mountaineering techniques obtained in a specialized training course to map the geology, fracture patterns, and other concerns on canyon walls specifically applied to geotechnical characterization for bridge foundations and slope stability. Mr. Fergason has worked internationally in Canada, Mexico, Germany, Romania, and the Czech Republic and is has given dozens of professional presentations and authored over 10 papers. He has also been deeply involved with professional societies and served as the President of The Association of Environmental & Engineering Geologists (AEG) from 2014 to 2015.
