Project Information

Project Overview

Orange County Public Works (OCPW) has identified the need to widen Brea Boulevard consistent with the Orange County Master Plan of Arterial Highways (MPAH) designation of a Primary Arterial Highway.  The Brea Boulevard Corridor Improvement Project (Project) is located partially in the City of Brea and partially within unincorporated Orange County.  The Project begins at the intersection of Central Avenue/State College Boulevard and extends north to approximately 1,200 feet northeast of the intersection with Tonner Canyon Road, a total length of approximately 8,500 linear feet or 1.6 miles. In general, Brea Boulevard would be widened from two to four lanes (two lanes each direction) with six to ten foot wide shoulders, a 12 to 14 foot wide striped or raised median or a six foot wide median with a concrete barrier. 

The Project is intended to improve the corridor by enhancing the design of existing curves within the project limits to improve the distance a motorist can see. Additionally, the Project is intended to improve traffic flow by increasing the capacity of Brea Boulevard. This would be accomplished by widening Brea Boulevard, installing a new traffic signal at the intersection of Brea Boulevard and Tonner Canyon Road, and installing a new traffic signal approximately 1,150 feet north of Canyon Country Road to provide access for the adjacent oil field. 

The corridor improvements include replacing three bridges over Brea Boulevard, improving and extending various drainage crossings and utility bank crossings, relocating utilities and oilfield-related equipment (e.g., power transmission poles, oil lines, oil wells, telephone duct banks, etc.), replacing the existing traffic signal at Brea Boulevard and Canyon Country Road, and constructing multiple retaining walls. Some right-of-way (R/W) acquisition and driveway access point modification (e.g., driveway relocation or reconstruction) would also be required to accommodate the widened corridor.

To enhance wildlife movement, the Project includes installing a wildlife overpass west of the intersection of Brea Boulevard and Tonner Canyon Road. The overpass would provide a grade separated wildlife crossing at Brea Boulevard and provide wildlife connectivity for the designated Puente-Chino Hills Wildlife Corridor, which connects the Santa Ana Mountains to the Whitter Hills area. 

Comments Submittal - Public input regarding the appropriate topics for analysis to be included within the Draft Environmental Impact Report is being sought.
