Just when we thought Los Angeles’ football stadium craziness had cooled down, the owners of the San Diego Chargers and Oakland Raiders have unveiled plans for a 72,000 seat, $1.7 billion stadium on a 168-acre site in Carson—which should soon be on that city’s ballot—while Inglewood City Council approved a measure to build a stadium for the (for now) St. Louis Rams, originally floated by Rams’ owner Stan Kroenke.

The firm behind the Carson stadium, MANICA Architecture, is also designing a new arena for the Golden State Warriors in San Francisco’s Mission Bay. The architect of the Rams’ stadium is HKS. That office’s plan would include an 80,000 seat stadium and a 6,000 seat performance venue, both part of a mixed-use development on the site of Hollywood Park.

Showing how serious it is about moving an NFL team to LA, the NFL has launched a “Committee on Los Angeles Opportunities,” to “oversee the application of the relocation guidelines in the event that one or more clubs seek to move to Los Angeles. A half-dozen Southern California stadium proposals have been pitched in the past three years, although only the two most recent are attached to specific teams. Other proposals have been suggested for City of Industry, Downtown LA, Elysian Park, the Rose Bowl, and the Los Angeles Coliseum. The NFL has not had a team in Los Angeles since the Rams and Raiders both left after the 1994 season.
