Founded by Kenneth Laugenour and Lou Meikle in 1953, we began offering civil engineering and land surveying services to the largely agricultural area around Woodland and neighboring communities. Those two civil engineers/surveyors specialized in irrigation, drainage and other agriculture-related projects for the first few years. Kenneth Laugenour retired in 1970, leaving Lou Meikle to gradually grow the firm and expand its services to include residential, commercial and industrial land development, public works projects and comprehensive land surveying capabilities.
