Tassajara Valley near Mt. Diablo threatened
Hidden Valley Open Space (HVOS) is an amazing 1,000 acre grassland bowl at the northeast corner of San Ramon's Windemere development. Almost entirely circled by exposed ridges; in just a few minutes' walk you can reach world class views of the urban Tri-Valley, Mt. Diablo and vast expanses of agricultural land and open space to the east. Development pressures are re-kindling in the adjacent Tassajara Valley
For twenty years Save Mount Diablo and others have been defending the Tassajara Valley and hills, sensual grasslands stretching east of Danville’s Blackhawk and San Ramon’s Dougherty Valley, to the north of Dublin and Livermore. Tassajara Valley is just east of the county Urban Limit Line and San Ramon’s Urban Growth Boundary. It is an agricultural and open space buffer between preserved open spaces in every direction, linked by Camino Tassajara Road and Tassajara Creek, with headwaters to the north in Mt. Diablo State Park and Morgan Territory Regional Preserve. It is beautiful and endangered species habitat. County voters, including majorities in Danville and San Ramon, voted to place the Tassajara Valley outside of the urban growth boundaries in 2006. The “New Farm” project is a cynical attempt to break the urban growth boundaries and its developers are in the middle of a three-pronged approach aimed at gaining approval. If they’re successful, other parcels in the valley will follow and urban growth boundaries will be at risk throughout the county. Growth management will be destroyed. ..
