Measures E and G are both on the ballot. Whichever receives the most votes over 50 percent will develop the former Qualcomm Stadium site in Mission Valley.
Several dozen volunteers were in the new office near Montgomery Field, making phone calls, sending postcards and preparing for canvassing and social media efforts.
“We’re enjoying a groundswell of support from regular San Diegans who know that this is a rare opportunity to transform this crumbling stadium site,” said Nick Stone, project manager for La Jolla-based FS Investors.
“SoccerCity or Measure E is 100 percent funded by private dollars, produces twice the tax revenue — nearly $400 million — than any other plan, and will be completed in half the time,” he vowed.
The competing Measure G, known as SDSU West, has received high-profile backing from numerous community organizations, including the San Diego Regional Chamber of Commerce. But SoccerCity has the endorsement of Mayor Kevin Faulconer, and the San Diego County Taxpayers Association estimates it will produce the most tax revenue for the city.
Stone said groups backing the competing measure are relying on the “brand of the university, not the substance” of the plan,
The SoccerCity plan calls for a new 23,500-seat stadium for both Major League Soccer and SDSU football, a large river park, housing, a sports-and entertainment district and room for expansion of SDSU.
The competing SDSU West plan calls for a 35,000-seat college football stadium, commercial and residential space, a river park and a new SDSU academic campus.
“Measure G, the SDSU West initiative, is in full campaign mode with positive momentum toward election day,” said spokesperson Katy Temple on Tuesday. “It is the only initiative that creates the opportunity grow San Diego State University through an open and transparent process that will benefit our regional economy for generations to come.”
