Leonard Sansone has geotechnical expertise that includes numerous slope stability evaluations, foundation investigations and earth structure/levee designs for projects located throughout California.

Mr. Sansone’s expertise includes project management and development of subsurface investigation and laboratory testing programs, analysis of geotechnical field and laboratory data, analysis, preparation and review of technical reports, and direction of geotechnical construction testing and observation programs. He has experience in the selection of design criteria for design of pipelines, earth retaining structures/levees, shallow and deep foundation systems, pavements, retaining walls and surface and subsurface drainage systems. In addition, he also has experience in conducting settlement, slope stability and seismicity/seismic risk evaluations, and observing geotechnical construction on weak and compressible soils.

Mr. Sansone’s civil design experience includes preparation of layouts for dam and reservoir facilities, hydrologic evaluations to determine reservoir spillway sizing, culvert and grading design, and design of erosion and sedimentation control facilities for Stormwater Pollution and Prevention Plans (SWPPPs). He also has experience with solid waste facilities and has designed landfill module expansions and closures.
