Marin General Hospital released a draft environmental impact report for a roughly $500 million rebuild project that will bring the 235-bed level III trauma center in line with state seismic measures while improving other features. The release of the draft EIR marks the first formal step by the hospital, overseen by the Marin Healthcare District, on the massive project, just weeks after it was declared the "prevailing party" in a dispute with Sutter Health, which operated the facility until 2010.
