Walnut sits on the southern slopes of the San Jose Hills, and 83 percent of its occupied housing is owner occupied. Its housing is master planned single family, with homes ranging from about 1,800 up to 11,200 square feet. Large houses on sloping ground usually means substantial decks and terraces, and stairs that carry real distance between levels.
On slope, the drainage decision outranks the coating decision. Water shed off an edge onto a hillside is a problem deferred rather than solved, so we look at where it goes after it leaves the deck. Owners who plan to stay in a house for decades tend to appreciate that distinction, because they are the ones who would live with the consequences.
