In Granite Oaks the boulders under the decomposed granite make excavating the tank the hard part, so we work the drainfield around the embedded rock we cannot dig through, set it to fall, and grade the field away from the low corner where runoff pools.
Granite Oaks lies at the base of Granite Mountain in the Williamson Valley area, one to three acre lots with horse privileges and the mountain itself as the backdrop. The name is honest: this is granite ground, and the closer a lot sits to the mountain, the more of it you find once you break the surface.
Expect decomposed granite over solid rock and scattered boulders, some of them big enough to reroute a driveway. Lots near the base of the mountain carry more slope and more embedded rock than the flats farther out, so cut and fill has to account for shelves you cannot dig through. Runoff comes off the higher ground fast in July, and it looks for the low corner of the lot every time.
Building against a granite mountain means the difference between a level pad and a settling slab often comes down to how the rock was handled, not how the dirt was moved. An owner here needs a contractor who can rip and shape rock and set drainage that respects water coming off the high side.
