The project would add new housing options, with 90 affordable units and a mixed-use development focused on health and wellness.

AUSTIN, Texas — The Greater Austin YMCA took the next step on Monday in a major plan to redevelop its TownLake campus.

The organization submitted a Planned Unit Development (PUD) application to the city in partnership with developer Millenium Partners that would transform the Downtown Austin YMCA into a mixed-use community.

The proposal includes a new 110,000-square-foot YMCA, affordable and market-rate housing, childcare and expanded health and wellness services. The plan also calls for 90 affordable housing units in partnership with Foundation Communities.

Developers said the project would include major sustainability upgrades, restore nearby habitat along Lady Bird Lake and generate more than $1 billion in taxable value, while creating hundreds of jobs.

“The PUD submission marks a major milestone in our greater vision for the future of Austin,” said Kathy Kuras, president and CEO of the Greater Austin YMCA. “This project is a once-in-a-generation opportunity to transform downtown Austin and address our community’s most pressing needs. Together with Millennium Partners, we’re creating a vibrant community where families can live, learn, work, and play.”

The project must still go through the city’s review and approval process.
