This collection represents 89 years of the Robert Martin and Associates civil engineering firm, and later U.S.A. Architects, in Ventura County. It includes the work of six civil engineers and their staff, with the bulk of the collection created by Milton Ramelli, Harry B. Waud, Robert Martin, T. William "Bill" Hale, and Ed Campbell. Between 1924 and 1963, the firm went through many changes in partners and eventually was incorporated as Robert Martin and Associates. Ed Campbell would later buy the firm and rename it U.S.A. Architects. This collection is the working files of Martin and Associates, and to a lesser extent U.S.A. Architects. This includes project files, drawings, and reference maps for various civil engineering and surveying projects, as well as architectural plans.
