  15. Infiltration Rate High at the surface Low at Restrictive Layer Infiltration rate is determined for the surface horizon.

  16. Available Water Bh horizon = cemented; 27 inches 150 cm = 59.06 inches Depth AWC In In/In 00 – 05 - 0.05 – 0.10 05 – 26 - 0.02 – 0.05 25 – 29 - 0.10 -0.15 “Available water capacity is calculated for the upper 150 cm or to a root restricting layer, whichever is shallower. The rationale for this convention is the assumption that this would be the main available soil volume for plant root withdrawal of water.”

  17. Hydraulic Conductivity Gm/hr A = 21.2 – 35.1 E = 27.2 – 29.2 Bh1= 2.6 Btg= 0.4 Hydraulic conductivity is determined for the most limiting layer in the soil profile.

  18. Soil Wetness Class HWT= 12 inches, perched, Jun-Oct Class 4 = wet between 25-50 cm

  19. Soil Interpretations Dwelling with Basement: Severe: wetness Septic Tank Absorption Fields: Severe: wetness, slow percolation, cemented pan Local roads and streets: Severe: wetness

  20. Position of Site - Depression Parent Material - Marine Soil Slope - Nearly level Surface Runoff - Medium Erosion Potential - Medium

  21. Soil Slope Surface Runoff Nearly level & Medium

  36. Hydraulic Conductivity Gm/hr A = 25.4 – 36.7 Bw = 14.2 – 35.5 Btg= 0 – 0.5 Hydraulic conductivity is determined for the most limiting layer in the soil profile.
