Specialized Design


Marvin E. Davis & Associates has completed numerous specialized civil engineering projects, most of which have a strong soil- or geotechnical-related scope or are related to difficult site development.  These include Tahoe Regional Planning Agency Soils/Hydrologic Investigations; radon studies; erosion control measure (“BMP”) design for residential and commercial sites; grading, drainage and subsurface drainage designs for residential and small commercial sites; on-site disposal systems; pipeline design; water storage ponds; shoreline protection and breakwater projects; stream channel repair and reinforcement; design plans for rockery, Redi-Rock, Keystone, and soil nail retaining walls; and slope repairs.
