THE CONTRA COSTA COUNTY Drainage Project resulted from a request made of the Agricultural Extension Service at a county planning meeting held in 1964. The project involved the cooperation of the Extension Service, East Contra Costa Irrigation District, U. S. Soil Conservation Service, and USDA's Agricultural Stabilization Committee. The main objectives were: (1) to test spacing intervals for tile lines under soil conditions in the Brentwood and Byron areas of Contra Costa County as a basis for planning drainage projects for the two areas; (2) to test various tile materials with both gravel and glass fiber envelopes; and (3) to correct a serious drainage situation in a walnut orchard in Brentwood.
