Gov. Arnold Schwarzenegger said Thursday he had signed a bill allowing the construction of a 75,000-seat stadium that developers hope will lure an NFL team back to the Los Angeles area.

Schwarzenegger said he signed the environmental exemption bill last week but saved the announcement for a press conference in Industry, where the stadium would be built. The bill would nullify a lawsuit filed by residents in nearby Walnut over the project's environmental impact. Schwarzenegger called the lawsuit frivolous.

Majestic Realty Co. is heading the stadium project after helping develop Staples Center in downtown Los Angeles.

Majestic has targeted seven teams as candidates to move to the Los Angeles area, including the Raiders and 49ers. The others are the San Diego Chargers, Buffalo Bills, Jacksonville Jaguars, Minnesota Vikings and St. Louis Rams.

The firm has said those teams are in stadiums that are either too small or can't be updated with luxury box seats or other revenue sources an NFL club needs to thrive.

Majestic CEO Ed Roski has vowed to build the stadium without any public support beyond the $150 million bond measure by Industry to pay for infrastructure improvements, which the developers plan to repay through ticket sales and parking fees.

Roski also said he's prepared to break ground as soon as a team is locked in and that he's confident that he can raise the $800 million needed for the stadium despite tight credit

"We don't feel at this time that it's going to be a challenge," he said.
