Hidden OaksThe developer of the 537 acre property  submitted a revised project that reduces the footprint of the project and number of units from 107 to 53. However, the site is now owned by a new developer and the new site plans are unknown. The site is located on Carbon Canyon Road across from the Circle K store.


  • The new owner’s project plans have not yet been produced.


  • This site is ground zero of the uprising that led to Measure U. Developers in the 1990s ripped out hundreds of mature oaks on this property. They tried to save some but left them to die along Carbon Canyon Road.
  • Outraged residents sponsored an initiative, Measure U, that passed overwhelmingly. This initiative requires projects to not build more than the number of units allowed in the General Plan.
  • Hills For Everyone advocated during the most recent project proposal to keep the units along the road and saves the back side of the property which is contiguous with Chino Hills State Park.
