USDA's description

The Laewest series consists of very deep, moderately well drained soils that formed in clayey flood basin deposits on alluvial plains or deltas of the Beaumont Formation of Pleistocene Age. These nearly level to gently sloping soils are on broad flat coastal plains. Slope ranges from 0 to 8 percent. Mean annual precipitation is about 940 mm (37 in) and the mean annual air temperature is about 21.5 degrees C (70.5 degrees F).
