Compressibility is inferred <br />from the Unified classification of the soil. The properties that affect the ease and <br />amount of excavation include d * epth to a water table, ponding, flooding, slope, depth <br />to bedrock or a cemented pant hardness of bedrock or a cemented pan, and the <br />amount and size of rock fragments. <br />The ratings ar ebothvorbsJondp <br />numerical, Rating class terms )n <br />indicate the eextent <br />to which the soils are limited bv all of the soil features that affect the specified use. <br />"Not limited" indicates that the :soil has features that are very favorable for the <br />specified use.
