Orange and Riverside counties, and 4,500 come from outside the state. A stadium built at this site was seen as having the ability to attract more fans from Orange County, Riverside County, and Los Angeles. There were problems with the site if the Chargers chose to build the stadium there. The golf course is zoned parkland, and voters would have had to approve a zoning change for a stadium to be built. Also some believe that the stadium, if it was built, had the possibility of causing traffic and environmental issues to the area, especially during game days.

Another proposed Chula Vista option fell on private property, owned by residential homebuilder, HomeFed Corp, which owns 3,000 acres (12 km2) in the Otay Ranch area, had conducted talks with the Chargers.
