News Summary

San Antonio’s ambitious Project Marvel aims to reshape the downtown area with a $4 billion investment, featuring a new arena for the Spurs, an expanded Convention Center, and other facilities. While local leaders support the project, a recent poll indicates mixed public sentiments, particularly regarding funding sources. Upcoming propositions for venue tax funding will be voted on in November, raising concerns about transparency and local needs. Community discourse continues as residents weigh the potential impact on tourism and local infrastructure.

San Antonio is poised for a transformative $4 billion development initiative known as Project Marvel, which aims to reshape the downtown landscape with key components designed to boost tourism and enhance the local hospitality industry. Key features of the project include a new arena for the San Antonio Spurs, an enhanced Convention Center, a new convention headquarters hotel, an events center, a reimagined Alamodome, a land bridge, and a mixed-use district.

Support for Project Marvel is mixed. While local leaders refer to the proposed Spurs arena as “transformational,” a poll conducted by UT San Antonio’s Center for Public Opinion Research indicates that likely voters are leaning towards rejecting venue tax funds specifically for the new arena. Despite this, there remains a positive overall sentiment towards the project, even in the face of several concerns.

Project Feature Description
New Arena A sports facility for the San Antonio Spurs.
Expanded Convention Center Enhancements to existing facilities to accommodate larger events.
New Hotel Headquarters hotel for conventions to support tourism.
Events Center A space for a variety of community events.
Reimagined Alamodome Improvements to a significant local venue.
Land Bridge A new infrastructure feature to improve connectivity.
Mixed-Use District Residential, commercial, and recreational spaces in one area.

Funding for Project Marvel is primarily sourced from property taxes generated by future developments in Hemisfair, which will back the bonds needed for the arena. The city plans to create a tax increment reinvestment zone (TIRZ) to assist with financing. An additional $1.4 billion in projects from Spurs Sports & Entertainment and various real estate developers is projected over the next 12 years. Municipal officials are also looking to extend the Hemisfair TIRZ, which is currently set to conclude in 2037.

Thanks to recent Texas legislation, a new project finance zone will enable San Antonio to access a portion of the state’s hotel tax revenue for the next three decades, potentially generating an estimated $2.5 billion to help fund the initiative. In addition, Bexar County is planning to support the arena’s financing through hotel and rental car taxes, estimating around $503 million in revenue directed towards the facility and its upgrades.

This November, residents will vote on two propositions related to the venue tax as part of the ballot, providing a critical opportunity for public input. Early voting begins on October 20, with Election Day slated for November 4. The development proposal has prompted community discussions about whether funding could be more effectively allocated to pressing local matters, such as infrastructure and affordable housing projects.

Concerns regarding transparency in the funding process and the feasibility of future developments have arisen through public forums. San Antonio has previously invested in ambitious downtown projects, historically yielding mixed outcomes. Significant skepticism persists, particularly in light of a high vacancy rate for Class A office space downtown, reported at 40.2% as of the third quarter of 2025, and a perceived lack of firm commitments from developers regarding anticipated projects.

What is Project Marvel?

Project Marvel is a $4 billion downtown development project in San Antonio which includes a new arena for the San Antonio Spurs, an expanded Convention Center, and other significant facilities aimed at enhancing tourism.

Residents will vote on the two propositions on November 4, with early voting beginning on October 20.

What are the main funding sources for this project?

Key funding sources include property taxes from future Hemisfair development, a tax increment reinvestment zone, and hotel and rental car taxes from Bexar County.

What are some concerns related to Project Marvel?

Concerns include the lack of a strategic unifying vision, high downtown vacancy rates, the transparency of the funding process, and whether funds could be better allocated to local issues such as infrastructure.
