APPENDIX 9-5-2 (Cont.) <br /> Soil Interpretations <br /> FOOTNOTES <br /> C. (Moderately high runoff potential). Soils have slow infiltration rates when thoroughly wetted and consist chiefly of soils with a layer that impedes <br /> downward movement of water, soils with moderately fine to fine texture, soils with slow infiltration due to salts or alkali, or soils with moderate <br /> water tables. These soils may be somewhat poorly drained. This category also includes well and moderately well drained soils with slowly and very <br /> slowly permeable layers (fragipans, hardpans, hard bedrock, and the like) at moderate depth (20-40 inches). (Includes soils in Albic or Aquic <br /> subgroups; soils in Aeric subgroups of Aquents, Aquepts, Aquolls, Aqualfs, and Aquults in loamy families; soils other than those in group D that are in <br /> fine or clayey families except those with kaolinitic, oxidic, or halloysitic mineralogy; Humods and Orthods; soils with fragipans or petrocalcic <br /> horizons; soils in shallow families that have permeable substrata; soils in Lithic subgroups that have rock that is pervious or cracked enough to allow <br /> water to penetrate). <br /> D. (High runoff potential). Soils have very slow infiltration rates when thoroughly wetted and consist chiefly of clay soils with a high swelling <br /> potential, soils with a permanent high water table, soils with a claypan or clay layer at or near the surface, soils with very slow infiltration due to <br /> salts or alkali, and shallow soils over nearly impervious material. These soils have a very slow rate of water transmission (Includes all vertisols; <br /> all Histosols; all Aquods; soils in Aquents, Aquepts, Aquolls, Aqualfs, and Aquults except for aeric subgroups in loamy families; soils with natric <br /> 10 horizons; soils in Lithic subgroups that have impermeable substrata; and soils in shallow families that have impermeable substrata). <br /> 0 <br /> C <br /> rn <br /> c <br /> CD <br /> m <br /> a <br /> 00 <br /> 00 <br />
