The quest for a new stadium to house the 49ers has long focused on Santa Clara but the team isn’t putting all their eggs in that basket.

Santa Clara plans require the team to cut land deals with both the city and Cedar Fair, which owns the Great America theme park. The stadium would be built in Great America’s parking lot. The city said they can still go forward without Cedar Fair but it would raise costs because the amusement park is guaranteed parking as part of their deal with the city.

There’s already a spending gap between what the city is willing to put up and what the team says it will cost and any growth in that seems likely to imperil the deal. As does Santa Clara’s request that the team pay rent on any land it occupies. If everything can be worked out in time, the plan would go before the city’s voters in November.

All of that has led the team to seek insurance and/or leverage in other locations. They’re not without their own drawbacks, however.

There’s a July vote in San Francisco about redeveloping the Hunters Point area with a new stadium, housing and commercial space. Proposition G, as it’s known, has been polling well but there’s another Proposition on the ballot which would require the city to use the area for affordable housing. That would negate plans for a stadium.

Recently, the team started discussions with Brisbane, just outside San Francisco, about using a waterfront landfill site for a stadium. The current landowners, Universal Paragon Corp., want to transform the area into a hub of green tech development and told the San Francisco Chronicle that “it’s not really what we envision for the site.”

Seems a lot of trouble to go through for the chance to watch J.T. O’Sullivan fling the pigskin.
