Soils are assigned to one of four Surface Texture groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long- duration storms. Water Content, 15 Bar The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A /D, 8 /D, and C /D). The groups are defined as follows: Water Content, One -Third Bar Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist Soil Qualities and Features mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. AASHTO Group Classification (Surface) Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture Depth to a Selected Soil Restrictive Layer to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a Depth to Any Soil Restrictive Layer layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Drainage Class Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These Frost Action consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. Frost-Free Days http : / /websoiIsurvey.nres.usda.gov /app /WebSoiISurvey.aspx 2/27/2014
