What the ground in Gilbert is like

The USDA soil survey rates mapped ground in Gilbert for septic drain-field suitability across roughly 69 square miles. About 76% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Gilbert, 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 96% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement96.4%
• Flooding6.2%
