Liberty Quarry Update

Granite Construction’s appeal to the Riverside County Board of Supervisors for reconsideration of plans for a quarry near Temecula, Calif., will be the subject of another round of hearings, according to

The county Planning Commission voted 4-1 in August to deny permits for Watsonville-based stone producer’s proposed 414-acre Liberty Quarry project. Five public hearings were held in 2011 on the proposed quarry, which would lie just north of the boundary separating Riverside and San Diego counties, east of the Santa Margarita Ecological Reserve, adjacent to Interstate 15 and Rainbow Valley Boulevard.

The Temecula City Council and the Pechanga Band of Lusieno Indians, whose reservation borders the project zone, opposed it. A final environmental impact report was issued in March 2011 and found that noise, air, traffic and land-use problems arising from the quarry could be mitigated. Planning commission staff recommended that the board vote in favor of it, providing various conditions were met. Granite Construction sought a 75-year operating window, during which it planned to remove an estimated five million tons of construction-grade aggregate.
