What the ground in Felton is like

The USDA soil survey rates mapped ground in Felton for septic drain-field suitability across roughly 4.6 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 Felton, 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:

• Slope81.9%
• Depth to bedrock77.8%
• Seepage, bottom layer56.9%
• Slow water movement43.1%

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.
