Newsom says his city will go ahead with plans for a new stadium site as part of the Hunters Point Shipyard redevelopment project, the San Francisco Chronicle reports.
Tuesday voters in Santa Clara approved Measure J clearing the way for the San Francisco 49ers plan to build a $937 million stadium in their community.
The vote came after the football team spent more than $4 million on a campaign in a city with only 46,000 voters.
Opponents of a stadium in Santa Clara charged it would be a financial loser for the city.
The San Francisco mayor says the numbers don't work for a Santa Clara stadium and when the 49ers realize that his city's plan will look better and better.
