What the ground in Cottonwood is like

The USDA soil survey rates mapped ground in Cottonwood for septic drain-field suitability across roughly 28 square miles. About 86% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Cottonwood, 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 59% of the rated ground here.

The limiting features the survey records most often here:

• Slope58.6%
• Slow water movement24.9%
• Depth to cemented pan21.3%
• Depth to bedrock14.2%

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.
