PEBBLE BEACH, Calif. (AP) — After the Pebble Beach Co. paid $820 million in 1999 for 2,600 acres of prime California coastal real estate, the company unveiled plans for a new golf course, revamped polo fields and 100 new mansions.But in a see-saw battle, the project near the famed Pebble Beach Golf Links won local approval at the ballot box but was rebuffed by California's chief coastal regulator.Finally, years of negotiations recently yielded a compromise between the California Coastal Commission's staff and the company, which is backed by Arnold Palmer, Clint Eastwood and others.On Wednesday, the commission is scheduled to vote on a scaled back plan for 90 homes and no golf course, despite the involvement of links legend Palmer.The plan would improve public access to the breathtaking site and conserve 635 acres of forest, which is covered by rare Monterey pines.
