What the ground in Coatesville is like

The USDA soil survey rates mapped ground in Coatesville for septic drain-field suitability across roughly 1.8 square miles. About 64% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Coatesville, the leading limit is depth to bedrock: rock sits close enough to the surface that there is not enough soil column above it for a conventional field to sit in. Effluent needs that depth to disperse; when bedrock comes up, the workable layer runs out. The survey flags that limit on about 79% of the rated ground here.

The limiting features the survey records most often here:

• Depth to bedrock79.3%
• Slope43.8%
• Seepage, bottom layer32.8%
• Slow water movement19.5%

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.
