The Oakland A’s will have an easier time financing and building a proposed new ballpark at the Port of Oakland’s Howard Terminal after Gov. Gavin Newsom signed two bills Friday to help the team.

AB1191 by Assemblyman Rob Bonta, D-Alameda, streamlines the process for the A’s to receive the necessary permits for the stadium. The law gives the State Lands Commission, which manages 4 million acres of tidelands and submerged lands, the authority to decide whether the ballpark is an appropriate use of the site at the Port of Oakland.

SB293 by Sen. Nancy Skinner, D-Berkeley, allows Oakland to create a new tax district to pay for roads, walkways, electrical and sewer lines and other infrastructure near the proposed stadium.

The A’s hope to open a privately funded, 35,000-seat stadium, along with nearby housing and commercial developments, on a 50-acre site at the Oakland Estuary near Jack London Square.

The project is opposed by shipping companies and port workers concerned that the ballpark would obstruct a key basin where dozens of ships load and unload each week, but city leaders are backing the plan. Mayor Libby Schaaf has said the city could consider a $200 million infrastructure deal to help cover the costs of roads and utility improvements around the site.

The next step is the completion of an environmental impact report, which is expected by the end of the year. If approved by the Oakland City Council and the port commission, the A’s will be able to lease the Howard Terminal site for 66 years. The team is aiming to break ground in 2021 and open the new ballpark for the 2023 season.
