Marlene K. Jackson, CE, GE
Principal Geotechnical Engineer
Ms. Jackson joined Geosphere in 2017 and has been providing geotechnical engineering services in the San Francisco Bay Area for over 30 years. With a Bachelor’s degree from Harvard University in Geologic Science and a Master’s degree in Geotechnical Engineering from UC Berkeley, her background in geology, earth science, and geotechnical engineering provide a relatively unique combination of study that facilitates recognition of the relationships between subsurface materials and their engineering characteristics. Ms. Jackson has been responsible for business development and management of geotechnical engineering services including completion of geotechnical investigations, soil sampling and laboratory analyses, engineering analyses, preparation of geotechnical recommendations and design criteria, report preparation, plan review, construction observation and testing services, and expert witness services as well as other geotechnical engineering related consultation. She has provide geotechnical engineering consultation for a wide variety of projects including schools, medical facilities, fire stations, commercial construction, retail facilities, mixed-use developments, and residential structures. Ms. Jackson has experience performing engineering analyses for design of both deep and shallow foundations systems, restrained and un-restrained retaining walls, underground utilities and structures, flexible pavement, reinforced earth embankments, static and dynamic settlement, bearing capacity, resistance to lateral loads, lateral earth pressures, static and pseudo-static slope stability, liquefaction evaluation, post-tensioned slab, and effects of surcharge loads. Ms. Jackson has worked on projects which included complex slope stability issues involving existing residences on actively moving landslides, shoreline and levee stability, and emergency landslide repair.
