The Oakland A’s are showing off the newest renderings of their proposed 35,000-seat ballpark at Howard Terminal near Jack London Square. The Port of Oakland’s board of commissioners have approved giving the A’s four years to conduct an environmental review and obtain land use permits, steps needed for them to eventually lease the 50-acre site. The team plans to play ball at the new stadium by 2023. The A’s also released new renderings of their plans for the existing Coliseum site.
