SUNOL, CA-San Francisco’s Board of Supervisors this week gave a collective thumbs-up to the Mission Valley Rock Co.’s plan to develop a 242-acre granite-mining quarry near here. The quarry is slated for Alameda County land owned by San Francisco’s Public Utilities Commission. Mission Valley signed a 40-year lease for the land, and will pay the PUC an estimated $52-$64 million as part of the deal. The funds will help finance water-system improvements.

The project will be Mission Valley’s second quarry in Sunol. The first runs along Interstate 680. Elliston Vineyards initially wanted to lease much of the 242 acres for grape growing, but the PUC determined in October it would not bring as much revenue as the quarry.

Earlier this fall, a Save our Sunol activist filed a lawsuit in Alameda County Superior Court to block the quarry, but nothing has come of it yet. For five years, residents in Sunol, CA have battled against a proposed quarry, which will be located across the street from Sunol Glen Elementary School. They worry it will be an unattractive addition to this small town off Interstate 680, and say it poses a health threat to students and an environmental threat to the nearby Willis Polk Water Temple.
