Campbell has the feel of a small town inside a big valley, and the yards show it. San Jose Hardscapes does a lot of work in neighborhoods where the houses date from the 1920s through the 1950s, and the lots are smaller than what you'd find in the newer subdivisions farther south. A patio here isn't a sprawling slab. It's a few hundred square feet that has to earn its place.
Most of the ground is flat. That sounds easy, and it is for grading, but it also means water has nowhere dramatic to go. Clay holds it, old foundations take it in, and walkways heave when roots and moisture work on them from below.
Campbell also sits on land that was once covered in orchards, and you can still find the occasional old fruit tree on a residential lot. Those roots, along with the clay, are the two things we plan around more than anything else.
