<br />Custom Soil Resource Report <br />classification of the soil), the thickness of suitable material, and the content of rock <br />fragments. If the bottom layer of the soil contains sand or gravel, the soil is considered <br />a likely source regardless of thickness. The assumption is that the sand or gravel layer <br />below the depth of observation exceeds the minimum thickness. The ratings are for <br />the whole soil, from the surface to a depth of about 6 feet. <br />The soils are rated good, fair, or pooras potential sources of sand and gravel. A rating <br />of good or fair means that the source material is likely to be in or below the soil. The <br />bottom layer and the thickest layer of the soils are assigned numerical ratings. These <br />ratings indicate the likelihood that the layer is a source of sand or gravel. The number <br />0.00 indicates that the layer is a poor source. The number 1.00 indicates that the layer <br />is a good source. A number between 0.00 and 1.00 indicates the degree to which the <br />layer is a likely source. <br />Information in this table is intended for land use planning, for evaluating land use <br />alternatives, and for planning site investigations prior to design and construction. The <br />information, however, has limitations. For example, estimates and other data generally <br />apply only to that part of the soil between the surface and a depth of 5 to 7 feet. <br />Because of the map scale, small areas of different soils may be included within the <br />mapped areas of a specific soil. <br />The information is not site specific and does not eliminate the need for onsite <br />investigation of the soils or for testing and analysis by personnel experienced in the <br />design and construction of engineering works. <br />Government ordinances and regulations that restrict certain land uses or impose <br />specific design criteria were not considered in preparing the information in this table. <br />Local ordinances and regulations should be considered in planning, in site selection, <br />and in design. <br />Report-Source of Sand and Gravel (J&amp;J Stone Pit #1) <br />16 <br />[Onsite investigation may be needed to validate the interpretations in this table and to <br />confirm the identity of the soil on a given site. The numbers in the value columns range <br />from 0.00 to 0.99. The larger the value, the greater the likelihood that the bottom layer <br />or thickest layer of the soil is a source of sand or gravel]
