What the ground in Beaverton is like
The USDA soil survey rates mapped ground in Beaverton for septic drain-field suitability across roughly 20 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 Beaverton, 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 100% of the rated ground here.
