Component Percent Cutoff: None Specified <br />Tie-break Rule: Higher <br />Recreational Development <br />Recreational Development interpretations are tools designed to guide the user in <br />identifying and evaluating the suitability of the soil for specific recreational uses. <br />Example interpretations include camp areas, picnic areas, playgrounds, paths and <br />trails, and off-road motorcycle trails. <br />Playgrounds <br />URB/REC - Urban and Recreational Land Uses <br />Playgrounds are areas used intensively for games, such as baseball and football, <br />and similar activities. Playgrounds require soils that are nearly level, are free of <br />stones, and can withstand intensive foot traffic. <br />The ratings are based on the soil properties that affect the ease of developing <br />playgrounds and that influence trafficability and the growth of vegetation after <br />development. Slope and stoniness are the main concerns affecting the development <br />of playgrounds. For good trafficability, the surface of the playgrounds should absorb <br />rainfall readily, remain firm under heavy foot traffic, and not be dusty when dry. The <br />soil properties that influence trafficability are texture of the surface layer, depth to a <br />water table, ponding, flooding, saturated hydraulic conductivity (Ksat), and large <br />stones. The soil properties that affect the growth of plants are depth to bedrock or a <br />cemented pan, saturated hydraulic conductivity (Ksat), and toxic substances in the <br />soil. <br />The ratings are both verbal and numerical. Rating class terms indicate the extent to <br />which the soils are limited by 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. Good performance and very low maintenance can be expected. <br />"Somewhat limited" indicates that the soil has features that are moderately <br />favorable for the specified use. The limitations can be overcome or minimized by <br />special planning, design, or installation. Fair performance and moderate <br />maintenance can be expected. "Very limited" indicates that the soil has one or more <br />features that are unfavorable for the specified use. The limitations generally cannot <br />be overcome without major soil reclamation, special design, or expensive <br />installation procedures. Poor performance and high maintenance can be expected. <br />Numerical ratings indicate the severity of individual limitations. The ratings are <br />shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations <br />between the point at which a soil feature has the greatest negative impact on the <br />use (1.00) and the point at which the soil feature is not a limitation (0.00). <br />The map unit components listed for each map unit in the accompanying Summary <br />by Map Unit table in Web Soil Survey or the Aggregation Report in Soil Data Viewer <br />Custom Soil Resource Report <br />26
