Cotton, Shires and Associates, Inc. (CSA) is a successor of William Cotton and Associates, formed by Bill Cotton in 1974. Bill has been widely recognized for his geological expertise and his excellent field mapping skills. CSA continues the tradition of a firm strongly rooted in detailed geologic observational skills combined with advanced geotechnical engineering and geophysical capabilities. We believe that the key steps of constraint recognition and site characterization must first be undertaken to allow completion of reliable geotechnical analyses and appropriate mitigation design.
