The County of Orange has proposed widening Brea Canyon Road from two lanes to four lanes. The widening would extend from Brea’s city limits to below the Los Angeles County line.


  • The County has held its second Notice of Preparation meeting in 2 years and is now writing the Draft Environmental Impact Report.


  • This area of the Puente-Chino Hills Wildlife Corridor is the only place wildlife can safely cross the 57 freeway from the Chino Hills to the Puente Hills (under the 57 freeway bridge).
  • Widening the road, adding lighting, and building median barriers will sever the connection that is necessary for wildlife to continue to move within the hillside system.
  • At the two public meetings that have been held in Brea, residents generally opposed the widening of Brea Canyon, viewing it as an invitation for more cars.
  • Residents also viewed it as taxpayer money improperly funding road improvements that should be paid for by Aera Energy’s proposed 3,600 unit project.
  • Los Angeles County has no intention of widening its portion of the road.
