What the ground in Belgrade is like

The USDA soil survey rates mapped ground in Belgrade for septic drain-field suitability across roughly 6 square miles. About 99% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Belgrade, the leading limit is large stones: the ground is full enough of rock fragments that trenching a field is mechanically hard and the soil fabric between stones is thin. Digging and bedding pipe become the practical problem before hydrology does. The survey flags that limit on about 88% of the rated ground here.

The limiting features the survey records most often here:

• Large stones88.0%
• Filtering capacity78.5%
• Seepage, bottom layer16.9%
• Slow water movement12.0%

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.
