What the ground in Boone is like

The USDA soil survey rates mapped ground in Boone for septic drain-field suitability across roughly 6.4 square miles. About 87% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Boone, 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 87% of the rated ground here.

The limiting features the survey records most often here:

• Slope86.6%
• Seepage, bottom layer73.3%
• Depth to bedrock46.3%
• Slow water movement40.7%

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.
