Soils are clayey, have a high <br /> water table, or are shallow to an impervious layer. <br /> Soil Drainage Class: Moderately well drained. Soils have a layer of low hydraulic <br /> iii conductivity,wet state high in the profile. Depth to water table is 3 <br /> to 6 feet. <br />} Hydric Status: Soil does not meet the requirements for a hydric soil. <br /> t <br /> Corrosion Potential-Uncoated Steel: MODERATE <br /> Depth to Bedrock Min: >0 inches <br /> Depth to Bedrock Max: >0 inches <br />?
