What the ground in Lawrence is like

The USDA soil survey rates mapped ground in Lawrence for septic drain-field suitability across roughly 35 square miles. About 98% of the rated ground is classed "Very limited", meaning the soil has one or more features unfavorable for a conventional drain field, and the limits generally cannot be overcome without major soil reclamation, special design or expensive installation.

In Lawrence, the leading limit is slow water movement: effluent does not drain through the soil fast enough, so a conventional field can back up or pond when the ground cannot keep pace. The survey flags that limit on about 83% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement83.5%
• Depth to saturated zone60.6%
• Depth to bedrock25.7%
• Flooding25.4%

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.
