What the ground in Sylva is like

The USDA soil survey rates mapped ground in Sylva for septic drain-field suitability across roughly 3.2 square miles. About 98% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Sylva, the leading limit is slope: the ground falls steeply enough that a level trench line is hard to hold. A drain field has to sit across the grade without concentrating flow downhill; on steeper parcels that layout gets tighter. The survey flags that limit on about 82% of the rated ground here.

The limiting features the survey records most often here:

• Slope82.3%
• Slow water movement81.4%
• Seepage, bottom layer38.4%
• Flooding17.4%

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.
