What the ground in Burnsville is like

The USDA soil survey rates mapped ground in Burnsville for septic drain-field suitability across roughly 1.6 square miles. About 95% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Burnsville, 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:

• Slope86.8%
• Slow water movement83.3%
• Seepage, bottom layer54.0%
• Flooding7.8%

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.
