What the ground in Savannah is like

The USDA soil survey rates mapped ground in Savannah for septic drain-field suitability across roughly 109 square miles. About 100% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Savannah, the leading limit is depth to the saturated zone: the water table sits so close to the surface that a drain field has little dry soil left underneath it. Effluent needs unsaturated ground to treat and disperse; when that column is thin, the field has nowhere safe to go. The survey flags that limit on about 97% of the rated ground here.

The limiting features the survey records most often here:

• Depth to saturated zone96.9%
• Slow water movement88.2%
• Flooding59.4%
• Seepage, bottom layer27.2%

This is survey data for mapped areas, not a substitute for a site evaluation on your own lot. Conditions on a single parcel can differ from the map.
