What the ground in Rancho Cucamonga is like

The USDA soil survey rates every mapped parcel for its suitability as a septic drain field. Across Rancho Cucamonga's 46.5 square miles, 100.0% 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:

  • Seepage, bottom layer99.7%
  • Flooding85.1%
  • Filtering capacity73.0%
  • Large stones19.6%

The most common soil series underfoot: Tujunga, Soboba, Hanford.

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.
