Foes say development would choke bridge traffic and worsen air

Proposed redevelopment on Treasure Island would increase traffic jams on the Bay Bridge, lengthening commute times and exacerbating Bay Area air pollution, critics say. Residents, environmental organizations and local agencies voiced those concerns this fall in almost 700 written comments on proposed new residential and commercial development that planners have said would make the island a world-class green neighborhood. Comments about the project’s draft environmental impact report submitted by the September deadline expressed deep misgivings with the plan by the city and the developer to limit driving on and off the island.
