Voters in Bexar County, Texas, approved two ballot measures on Nov. 4 — Proposition A and Proposition B — related to raising certain taxes and allocating revenue from the taxes towards the development of local arenas.

Both measures increased the county's hotel occupancy tax rate from 1.75% to 2% and established that revenue from both the hotel and the county's short-term motor vehicle rental taxes will be used for stadium projects.

Although both measures draw from the same tourist tax proceeds, they fund different stadium projects.

Proposition A, which passed with a margin of 56% to 44% as of Nov. 14, contributes approximately $191.8 million worth of upgrades and renovations to local stadiums, such as the Frost Bank Center, the Freeman Coliseum, and the San Antonio Stock Show & Rodeo Grounds.

Proposition B — also called Project Marvel — passed with a smaller margin of 52% to 48%. The measure dedicates around $311 million from hotel occupancy and vehicle rental taxes to the construction of a new arena in downtown Hemisfair Park for the San Antonio Spurs, who will be leaving the Frost Bank Center after calling it home for over 20 years.

These measures are among the 2025 ballot measures related to using tax revenue or other economic plans for professional sports stadiums. Last year, there was at least one in Kansas City, Missouri, where voters rejected the renewal of a sales tax to fund stadium improvements for the Kansas City Chiefs and Kansas City Royals. In 2023, there were two measures in Tempe, Arizona, and Oklahoma City, Oklahoma. While Arizonans rejected the redevelopment plan for a professional sports franchise and entertainment district, voters in Oklahoma approved a sales tax measure to fund a development area for the Oklahoma City Thunder.
