Irvine, California

Irvine is divided into townships that are self-contained except for income-generating activities. The townships are separated by six-lane streets. Each township includes a spectrum of similar types of dwellings, along with shopping, religious institutions and schools. COPmmercial districts are checker-boarded in a periphery around the central townships.

All streets have landscaping allowances. Rights-of-way for powerlines are multiply-used, also serving as bicycle corridors, parks, and greenbelts to tie ecological preserves. The greenery is irrigated with reclaimed water.

The homeowner's associations are extremely powerful, controlling every facet of the appearance of one's home, including the age of car that can be displayed in a street, and the colors of houses.
