Have you always dreamed of buying a home close to, or in, the western foothills in Santa Clara County, such as Almaden, Los Gatos, Monte Sereno and Saratoga? Some of the prettiest parts of Silicon Valley are snuggled into the base of the Santa Cruz Mountains. With views of downtown San Jose and the southern San Francisco Bay Area on one side, and rolling, grassy and redwood & oak filled hills on the other, its certainly scenic. Additionally, these areas all tend to have very low crime and good schools.

As a saavy foothill-area buyer, you will want to understand some of the unique issues that this geography may present. The most important of these may well be the issue of water control and drainage.

The Santa Clara Valley, and most of the neighboring Silicon Valley areas, is composed of mostly clay soil. This is an extremely strong substance – so much so that settlers used it, mixed only with a little straw and water, to form adobe bricks for building.

The caveat with clay soil is that when it becomes wet, it expands, and when dry, it contracts. In fact, we call this condition ˜expansive. The amazing thing is that the clay is more powerful than concrete. And that is the problem for houses and other buildings if the ground is expanding, contracting, or alternating between the two.

What can a homeowner do? Its imperative to try to control the amount of water near (or under) the home as much as possible.
