LCC was founded in March of 1954 by Guenter K. “Gus” Leptien. Frank Cronin and Jasper Cooper joined him in 1955, and together they formed Leptien, Cronin, Cooper, a partnership. Leptien specialized in sanitary and assessment district engineering, Cronin specialized in road design and traffic engineering, and Cooper specialized in land surveying.

The partnership was incorporated as “Leptien, Cronin, Cooper, Inc.” in 1969. The principals of the firm served as interim City Engineer and District Engineer for local agencies and specialized in assessment districts and surveying. They were involved with the design of several major arterial roads in Contra Costa County including Willow Pass Road, Taylor Boulevard, Kirker Pass Road, Alhambra Avenue, the street system for the former site of Camp Stoneman military base and many local streets and roads.
