What the ground in Blaine is like

The USDA soil survey rates mapped ground in Blaine for septic drain-field suitability across roughly 5.6 square miles. About 100% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Blaine, the leading limit is depth to the saturated zone: the water table sits so close to the surface that a drain field has little dry soil left underneath it. Effluent needs unsaturated ground to treat and disperse; when that column is thin, the field has nowhere safe to go. The survey flags that limit on about 77% of the rated ground here.

The limiting features the survey records most often here:

• Depth to saturated zone77.2%
• Seepage, bottom layer43.0%
• Slow water movement35.2%
• Filtering capacity33.2%

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.
