<br />ADDENDUM 9-6-2 (Cont.) <br />Soil Interpretations <br />FOOTNOTES <br />C. (Moderately high runoff potent tal). Soils have slow infiltration rates when thoroughly wetted and consist chiefly of soils with a layer that impedes <br />downward movement of water, so 11s with moderately floe 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 drafned 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 1n Aeric subgroups of Aquents, Aquepts, Aquolls, Aqua lfs, and Aquul is fn loamy families; soils other than those in group D that are 1n <br />fine or clayey families except those with kaolinitic, oxidic, or halloys itfc mineralogy; Humods and Orthads; soils with fragipans or petroca lc lc <br />horizons; soils in shallow famll ies that have permeable substrata; soils in Lithic subgroups that have rock that fs 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 infiltra tton due to <br />salts or alkal7, and shallow sails over nearly imperv lous ma ter lal. These soils have a very slow rate of water transmission (Includes all verttsols; <br />all Nistosols: all Aquods; soils in Aquents, Aquepts, Aquolls, Aqualfs, and Aquults except for aerie subgroups in loamy families; soils with natrtc <br />.o horizons; soils in Lithic subgroups that have impermeable substrata; and soils 1n shallow families that have impermeable substrata). <br />rn <br />z <br />m <br />~~ <br />0 <br />0 <br />rn <br />m <br />
