The Town of Portola Valley (pop. 4500) is located west of Stanford University astride the world-famous San Andreas Fault. The Town values its environmental and historic heritage, its excellent public schools and its economical town government supported by a multitude of volunteers. An extensive trail system, scenic roads, open space and natural views contribute to the feeling of being in the country, as do architectural guidelines that stress "blending in." Commercial activity is encouraged to the extent that it primarily meets the needs of residents of the community. These factors have enabled the town to retain a rural ambiance reminiscent of earlier days.
