Similar soil are the Beaumont , Harris , Lake Charles , and Vamont series. Beaumont soils are more acid in the control section and receive more rainfall and have a P-E index more than 68. Harris soils have a mollic epipedon, are very poorly drained, and are saline throughout. Lake Charles soils have color value less than 3.5 to depths more than 12 inches in more than 60 percent of the pedon. Vamont soils have dominant chroma of more than 1.5 in the upper horizon and are more acid throughout.
Bacliff soils are on broad level to slightly depressional uplands.
The slope is generally less than 0.5 percent but ranges to 1 percent. The soil formed in alkaline marine clays of the Beaumont Formation of Pleistocene age. Mean annual precipitation is in the 35 to 45 inch rainfall belt although local areas average as high as 52 inches. F. The Thornthwaite P-E index is 56 to 68. These include the competing Lake Charles and Vamont series and the Dacosta , Edna , and Verland series.
