What the ground in Flagstaff is like

The USDA soil survey rates every mapped parcel for its suitability as a septic drain field. Across Flagstaff's 66.0 square miles, 96.8% of the rated ground is classed "Very limited", meaning restrictions severe enough that a conventional field is often unsuitable and an engineered system may be required.

The limiting features the survey records most often here:

  • Depth to bedrock71.3%
  • Slow water movement45.2%
  • Large stones23.7%
  • Seepage, bottom layer17.0%

The most common soil series underfoot: Brolliar, Tortugas, Daze.

This is survey data for the area, not a substitute for a site evaluation on your own lot. A soil scientist or your county health department tests the actual parcel, and the result can differ from the map.
