  "OVERVIEW": "The Freeport series consists of very deep, poorly drained, low saturated hydraulic conductivity (very slowly permeable) soils that formed in eolian deposits over loamy and clayey fluviomarine deposits. These nearly level soils occur on tidal flats on barrier islands. Slope ranges from 0 to 1 percent. Mean annual precipitation is about 1245 mm (49 in) and mean annual air temperature is about 20 degrees C (68 degrees F).",

  "REMARKS": {
    "section": "REMARKS",
    "content": "REMARKS: The series was formerly included in the Mustang series. The series was separated based on differences in water table depth and salinity.\nDiagnostic horizons and features recognized in this pedon are:\nParticle-size control section: 25 to 100 cm (10 to 40 in)\nOchric epipedon: 0 to 21 cm (0 to 8 in) (Ag horizon)\nEndosaturation and aquic conditions: 0 to 203 cm (0 to 80 in) (Ag, Cg1, Cg2,2Cg1 and 2Cg2 horizons)\nLithologic discontinuity: 128 to 203 cm (50 to 80 in).\nAdditional Comments: The lithologic discontinuity is evident as an increase in clay due to the Beaumont Formation and ancient Brazos River. This paleo-surface is deeper in pedons on Galveston Island and shallower on the southwest end of Follets Island. Some areas are firm enough during low tide to allow light vehicular traffic."
