The surficial fill materials <br /> were underlain by medium plastic lean clay with sand to a depth of about 7 feet, followed by low <br /> plastic sandy silt to a depth of about 11 feet below site grade, medium plastic sandy lean clay to <br /> a depth of about 16 feet, silty sand to a depth of about 19 feet, and lean clay to the depth explored <br /> of 25 feet. <br /> The National Resource Conservation Service Web Soil Survey refers to the near-surface soil with <br /> in the area of the proposed new septic system as belonging to the Jacktone-Urban Land Complex <br /> (Map Symbol 181). This soil is described as having very low capacity to transmit water.
