"A good place to grow up..."
Diamond Bar is a typical LA suburb around the intersection of the 60 adn 57 freeways. The area was developed for residential purposes beginning in the 1960s but the city wasn't incorporated until 1989. All of the time I was growing up in adjacent Walnut, Diamond Bar was just an unincorporated part of Los Angeles County. Diamond Bar is bordered by the cities of Walnut, Industry, Pomona, and Rowland Heights in Los Angeles County, Chino Hills in San Bernardino County, and Brea and unincorporated portions of Orange County.
Besides being made up of mostly middle and upper middle class housing developments and some decent ethnic restaurnants, Diamond Bar's most high profile resident is the South Coast Air Quality Management District which establishes and enforces air quailty regulations in a large portion of the Los Angeles Air Basin. This is where you would come to negotiate air permits for operation of your air pollutant-emitting equipment. They also maintain a hydrogen fueling station for your alternate fuel vehicle.
Although not the place for sightseeing, it does have a couple of good restaurants that the VT foodie may like to seek out. We both grew up in the area and return at least once each year (typically during the holidays) to visit family and friends. I constructed this page mainly for those tips. I hope they are helpful. See my Los Angeles page for links to other SoCal locales on which I have put up restaurant tips. IT'S ALL ABOUT EATING GOOD AND INTERESTING FOOD!
