Mountain House is a planned suburb of Tracy, CA and a fairly representative example of a modern planned suburb. Originally given development approval in the 1990s, the bulk of the single family houses were built in the pre-recession era, leading to a high percentage of vacancies. Though most of the land area is covered by (relatively) dense single-family housing, the development overall suffers from various zoning restrictions enacted by the Chamber of Commerce, most notably that there can be no commercial center in the development. This makes it a very vehicle-dependent suburb, and as such it lacks the “Jacobsian” factors that would make it walkable. Perhaps its only redeeming quality is the concentration of schools at regular intervals. Given that I-205 (the main road into Tracy) is almost at capacity, Mountain House is an excellent example of what not to do when planning a new suburb.
