What the ground in McMinnville is like

The USDA soil survey rates mapped ground in McMinnville for septic drain-field suitability across roughly 11 square miles. About 58% of the rated ground is classed "Somewhat limited", meaning the limits can usually be overcome or reduced by special planning, design or installation.

In McMinnville, 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 98% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement97.6%
• Slope52.2%
• Depth to saturated zone16.2%
• Flooding9.6%

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.
