The San Diego City Council voted unanimously put the SDSU West initiative on the November ballot where it will vie for voter attention with a competing proposal.
SDSU West is asking voters to support a $3 billion plan to redevelop the Mission Valley stadium site.
Ballot backers want to clear the way for the land to be sold to San Diego State University. The project encompasses 1.6 million square feet of classroom and research buildings. It would include 4,500 housing units, retail shops, a pair of hotels and a multi-use, 35,000-seat stadium for college football and other sports.
The land is three trolley stops from the built-out main campus.
SDSU West's Steve Doyle says it also calls for the school to build a River Park on nearby city owned land.
"This is the formalization by the council. Accepting the initiative that was circulated," Doyle said. "Petitions were verified and now we are officially on the ballot."
SDSU officials have for years eyed the city-owned Mission Valley site for expansion, and the property became available when the Chargers left for Los Angeles.

SoccerCity backers want to leverage a similar development with housing, a sports stadium, commercial space and a river park to lure a Major League Soccer Franchise to San Diego. That initiative qualified for the ballot last fall.
