Before San Bernardino County will permit a septic system on your Yucaipa land, you need a percolation test — proof of how fast your soil drains. It is the very first step for any new build on unsewered property, and it determines what kind of system you can put in.
Yucaipa soil is famously inconsistent: decomposed granite that drains fast on one parcel, clay lenses that barely drain on the next. We dig the test holes, run the PERC test to county protocol, log the soil profile, and hand the county exactly the documentation they want — then our in-house engineers design the system the results call for. One company, from the first test hole to the final inspection, which is why builders around the valley call us first.
