KINGS BEACH, Calif. (AP) — The Placer County Planning Commission is recommending approval of a sweeping development plan at a California ski resort in the Sierra north of Lake Tahoe. Nearly 100 people offered public comment before the panel voted 4-2 in Kings Beach Thursday night to approve the Squaw Valley expansion project and forward it to the county commission for final consideration. If approved, Squaw Valley Real Estate would be allowed to add nearly 1,500 motel rooms, condos, time shares and retail space in Olympic Valley over the next 25 years at an estimated cost of up to $1 billion. Plans also call for construction of a 90,000-square foot indoor adventure center and water park at the resort that hosted the 1960 Winter Olympics. Opponents say the project will generate too much pollution, traffic and noise. Critics including California Attorney General Kamala Harris say the increased traffic also would threaten public safety by raising the risk of traffic accidents, especially in Squaw Valley where just one road connects the valley to Highway 89 south of Truckee. "Because of the proximity of the proposed development to Lake Tahoe, we are concerned about the impacts the development will have within the Tahoe basin," she said in a 15-page letter to the commission earlier this week.
