The NFL’s Raiders are leaving for Las Vegas and the NBA’s Warriors are leaving for San Francisco. That means the Major League Baseball’s Athletics will soon be the only major pro sports franchise in Oakland. The team has pledged their support to the city and a desire to remain its flagship franchise, but that also means that it’s time for them to get a new stadium. To that end, the team is currently considering four sites in the city for what they hope will be a “baseball village.”

The most obvious option would be to stay right where they are and build a new stadium at the site of the Oakland Coliseum. While the immediate area is set up for parking and is located right on the BART line, it lacks any kind of connection to the surrounding neighborhood, defeating the idea of “a place where people can congregate,” which A’s President David Kaval said he’s looking to create.

Oakland Mayor Libby Schaaf really likes the idea of a waterfront park at the Port of Oakland’s Howard Terminal in West Oakland, and there’s been talk of putting a stadium here for some time. A waterfront stadium would be ideal, but the lack of freeway access or a BART station would be an issue.

A site near Laney College in Downtown Oakland has also been considered. Close to the Lake Merritt BART station and off I-880, it would be easy to access. Parking could be a nightmare, however, and the plan might require the college to tear down a portion of their athletics facilities, which were recently built.

The fourth possibility would put a new stadium in Brooklyn Basin, the massive development project that kicked off construction a couple years back on the city’s southern waterfront. Highway access is easy enough but that Lake Merritt BART station is currently the closest and that’s about a mile away.

If not sooner, the A’s will be the only pro game in town by 2020. It might take that long to figure out where their new home will be.
