The Olinda Landfill (official name: Olinda Alpha Sanitary Landfill)[1] is a landfill situated in Orange County, California, west of the northern portion of Chino Hills State Park in Carbon Canyon [2] in Olinda neighborhood of Brea City.
Facility size is approximately 565-acre (2.29 km2) with about 420-acre (1.7 km2) permitted for refuse disposal.
City of Brea (where the landfill is situated) alone provides about 30% of the total daily refuse deposited at the facility.
[2][3] Plans for postponement of landfill's closure by expansion of its area further into Carbon Canyon just west of Brea Olinda High School were cancelled in 1996 as Land and Water Conservation Fund decided to incorporate adjacent federal lands into Chino Hills State Park, rather than to dedicate it for landfill enlargement.
[2] After landfill closure the site will be landscaped to become part of Chino Hills State Park.
