North of the corridor is an active oil field and natural open space within unincorporated Orange County. North of the eastern end of the corridor on property is a commercial vehicle storage. East of the corridor is SR-57 and Tonner Canyon.
South and west of the corridor is the City of Brea and associated residential areas, with general commercial and public facility land uses. Immediately south of the middle stretch of the corridor are steep slopes containing additional oil field activity and the Humble Reservoir.
The Project involves widening Brea Boulevard from two to four lanes (two lanes each direction) between Canyondale Drive and the northern end of the corridor (approximately 1.5 miles), replacing and widening three functionally obsolete bridges, installing traffic signals approximately 1,200 feet north of Canyon Country Road and at the intersection of Brea Boulevard and Tonner Canyon Road, replacing the existing signal at Canyon Country Road, modifying existing driveway ingress/egress, installing a new wildlife overpass/land bridge, adding open graded asphalt concrete paving at the southern end of the corridor, and providing striping and installing new signage.
