The San Antonio City Council voted 7-4 to approve a non-binding terms sheet between the city and the Spurs over a new downtown arena.
The vote fell along the same lines as the earlier failed attempt to pause the negotiations.
Mayor Gina Oritz Jones requested that her colleagues support putting a future infrastructure bond up for a public vote.
The city has said the downtown area needs $220 million to $250 million in infrastructure improvements through an infrastructure bond to support the new arena and other Project Marvel Developments.
City Attorney Andy Segovia said the city council did not need to put such bond elections up for a public vote but could do so if it wished.
