Engineering Properties
This table gives the engineering classifications and the range of engineeringproperties for the layers of each soil in the survey area.
Hydrologic soil group is a group of soils having similar runoff potential under similarstorm and cover conditions. The criteria for determining Hydrologic soil group isfound in the National Engineering Handbook, Chapter 7 issued May 2007(http://directives.sc.egov.usda.gov/OpenNonWebContent.aspx?content=17757.wba).Listing HSGs by soil map unit component and not by soil series is a new conceptfor the engineers. Past engineering references contained lists of HSGs by soilseries. Soil series are continually being defined and redefined, and the list of soilseries names changes so frequently as to make the task of maintaining a singlenational list virtually impossible. Therefore, the criteria is now used to calculate theHSG using the component soil properties and no such national series lists will bemaintained. All such references are obsolete and their use should be discontinued.Soil properties that influence runoff potential are those that influence the minimumrate of infiltration for a bare soil after prolonged wetting and when not frozen. Theseproperties are depth to a seasonal high water table, saturated hydraulic conductivityafter prolonged wetting, and depth to a layer with a very slow water transmissionrate. Changes in soil properties caused by land management or climate changesalso cause the hydrologic soil group to change. The influence of ground cover istreated independently. There are four hydrologic soil groups, A, B, C, and D, andthree dual groups, A/D, B/D, and C/D. In the dual groups, the first letter is for drainedareas and the second letter is for undrained areas.
The four hydrologic soil groups are described in the following paragraphs:
Group A. Soils having a high infiltration rate (low runoff potential) when thoroughlywet. These consist mainly of deep, well drained to excessively drained sands orgravelly sands. These soils have a high rate of water transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. Theseconsist chiefly of moderately deep or deep, moderately well drained or well drainedsoils that have moderately fine texture to moderately coarse texture. These soilshave a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet. These consistchiefly of soils having a layer that impedes the downward movement of water orsoils of moderately fine texture or fine texture. These soils have a slow rate of watertransmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) whenthoroughly wet. These consist chiefly of clays that have a high shrink-swellpotential, soils that have a high water table, soils that have a claypan or clay layerat or near the surface, and soils that are shallow over nearly impervious material.These soils have a very slow rate of water transmission.
Depth to the upper and lower boundaries of each layer is indicated.

Texture is given in the standard terms used by the U.S. Department of Agriculture.These terms are defined according to percentages of sand, silt, and clay in thefraction of the soil that is less than 2 millimeters in diameter. "Loam," for example,is soil that is 7 to 27 percent clay, 28 to 50 percent silt, and less than 52 percentsand. If the content of particles coarser than sand is 15 percent or more, anappropriate modifier is added, for example, "gravelly."
Classification of the soils is determined according to the Unified soil classificationsystem (ASTM, 2005) and the system adopted by the American Association ofState Highway and Transportation Officials (AASHTO, 2004).
The Unified system classifies soils according to properties that affect their use asconstruction material. Soils are classified according to particle-size distribution ofthe fraction less than 3 inches in diameter and according to plasticity index, liquidlimit, and organic matter content. Sandy and gravelly soils are identified as GW,GP, GM, GC, SW, SP, SM, and SC; silty and clayey soils as ML, CL, OL, MH, CH,and OH; and highly organic soils as PT. Soils exhibiting engineering properties oftwo groups can have a dual classification, for example, CL-ML.
The AASHTO system classifies soils according to those properties that affectroadway construction and maintenance. In this system, the fraction of a mineral soilthat is less than 3 inches in diameter is classified in one of seven groups from A-1through A-7 on the basis of particle-size distribution, liquid limit, and plasticity index.Soils in group A-1 are coarse grained and low in content of fines (silt and clay). Atthe other extreme, soils in group A-7 are fine grained. Highly organic soils areclassified in group A-8 on the basis of visual inspection.
If laboratory data are available, the A-1, A-2, and A-7 groups are further classifiedas A-1-a, A-1-b, A-2-4, A-2-5, A-2-6, A-2-7, A-7-5, or A-7-6. As an additionalrefinement, the suitability of a soil as subgrade material can be indicated by a groupindex number. Group index numbers range from 0 for the best subgrade materialto 20 or higher for the poorest.
Rock fragments larger than 10 inches in diameter and 3 to 10 inches in diameterare indicated as a percentage of the total soil on a dry-weight basis. Thepercentages are estimates determined mainly by converting volume percentage inthe field to weight percentage.
Percentage (of soil particles) passing designated sieves is the percentage of thesoil fraction less than 3 inches in diameter based on an ovendry weight. The sieves,numbers 4, 10, 40, and 200 (USA Standard Series), have openings of 4.76, 2.00,0.420, and 0.074 millimeters, respectively. Estimates are based on laboratory testsof soils sampled in the survey area and in nearby areas and on estimates made inthe field.
Liquid limit and plasticity index (Atterberg limits) indicate the plasticitycharacteristics of a soil. The estimates are based on test data from the survey areaor from nearby areas and on field examination.
