Custom Soil Resource Report <br /> Soil Reports <br /> The Soil Reports section includes various formatted tabular and narrative reports <br /> (tables) containing data for each selected soil map unit and each component of <br /> each unit. No aggregation of data has occurred as is done in reports in the Soil <br /> Properties and Qualities and Suitabilities and Limitations sections. <br /> The reports contain soil interpretive information as well as basic soil properties and <br /> qualities. A description of each report(table) is included. <br /> Construction Materials <br /> This folder contains a collection of tabular reports that present soil interpretations <br /> related to sources of construction materials. The reports (tables) include all selected <br /> map units and components for each map unit, limiting features and interpretive <br /> ratings. Construction materials interpretations are tools designed to provide <br /> guidance to users in selecting a site for potential source of various materials. <br /> Individual soils or groups of soils may be selected as a potential source because <br /> they are close at hand, are the only source available, or they meets some or all of <br /> the physical or chemical properties required for the intended application. Example <br /> interpretations include roadfill, sand and gravel, topsoil and reclamation material. <br /> Source of Sand and Gravel JZA - Gravel) <br /> This table gives information about the soils as potential sources of gravel and sand. <br /> Normal compaction, minor processing, and other standard construction practices <br /> are assumed. <br /> Sand and gravel are natural aggregates suitable for commercial use with a <br /> minimum of processing. They are used in many kinds of construction. Specifications <br /> for each use vary widely. Only the likelihood of finding material in suitable quantity is <br /> evaluated.The suitability of the material for specific purposes is not evaluated, nor <br /> are factors that affect excavation of the material. The properties used to evaluate <br /> the soil as a source of sand or gravel are gradation of grain sizes (as indicated by <br /> the Unified classification of the soil), the thickness of suitable material, and the <br /> content of rock fragments. If the bottom layer of the soil contains sand or gravel, the <br /> soil is considered a likely source regardless of thickness.The assumption is that the <br /> sand or gravel layer below the depth of observation exceeds the minimum <br /> thickness. The ratings are for the whole soil, from the surface to a depth of about 6 <br /> feet. <br /> The soils are rated good, fair, or poor as potential sources of sand and gravel. A <br /> rating of good or fair means that the source material is likely to be in or below the <br /> soil. The bottom layer and the thickest layer of the soils are assigned numerical <br /> ratings. These ratings indicate the likelihood that the layer is a source of sand or <br /> gravel. The number 0.00 indicates that the layer is a poor source. The number 1.00 <br /> indicates that the layer is a good source. A number between 0.00 and 1.00 indicates <br /> the degree to which the layer is a likely source. <br /> 22 077 <br />
