Billionaire George Kaiser helped turn a neglected Arkansas River waterfront into a $465 million park. Millions now visit it

What happens when a city decides that a park should be more than a patch of green? In Tulsa, Oklahoma, the answer is Gathering Place a sprawling riverfront destination created through one of the largest privately funded public-space projects in the US. Stretching along the Arkansas River, the park was envisioned as a place where residents from different parts of the city could meet, play, explore and spend time together. What began as an ambitious dream backed by the George Kaiser Family Foundation eventually became a 100-acre public destination that has reshaped Tulsa’s waterfront.

From neglected riverfront to public destination

According to Gathering Place’s official history, the project began with a vision to transform nearly 100 acres of Tulsa’s waterfront into a dynamic environment for recreation, learning and community life. Construction officially began in 2014, and the first visitors arrived on September 8, 2018.

The scale of the project was striking. The Associated Press reported at the time of its opening that the park carried a $465 million price tag and initially covered about 66 acres, with plans to eventually reach 100 acres. It includes walking and cycling trails, athletic courts, lawns and playgrounds. AP described the opening as a major public event, with hundreds gathering for a parade, live music and activities for children. The report also noted that city leaders viewed the park not only as a recreational space but as a potential model for inclusivity.

A project designed around inclusion

The money behind Gathering Place was largely private. The George Kaiser Family Foundation says $465 million was invested by the foundation and its partners in creating the park, describing it as the largest gift to a municipality in US history. But the project's ambition went beyond simply constructing an expensive park.

The American Planning Association highlighted Tulsa’s long history of social and geographic inequality, noting that Gathering Place was conceived partly as a centrally located public space where residents could interact across longstanding divisions. The planning process generated roughly 1,400 ideas from the community, helping shape the park’s design and programming. That emphasis is visible in the park’s varied spaces. Visitors encounter playgrounds, gardens, trails, sports areas, lawns and waterfront landscapes rather than a single conventional recreational field.

The engineering behind the landscape

Gathering Place is also an example of how landscape design can dramatically alter an urban environment. The American Society of Landscape Architects says the project transformed 66 previously fallow acres beside the Arkansas River into an inclusive community hub. The development included a six-million-gallon irrigation pond, with material excavated from the site used to create significant changes in elevation across the park. Nearly 6,000 trees were planted, alongside more than 16 acres of meadow.

Wetland gardens were incorporated to provide habitat, help recharge groundwater and filter pollutants before they reach the Arkansas River and Crow Creek, according to ASLA. The project also created connections across major roads and linked the park with additional waterfront trails.

A park that became part of Tulsa’s identity

The scale of Gathering Place attracted attention well beyond Oklahoma. TulsaKids reported that $400 million of the $465 million construction cost came from families and businesses, with the George Kaiser Family Foundation providing the largest share. The park has since become part of Tulsa’s wider cultural landscape. In 2026, Gathering Place is also marking the centennial of Route 66 with programming built around the themes of “Neon, Nature, and Nostalgia”, connecting the park to Tulsa’s role along the historic highway.

More than a playground

Gathering Place ultimately represents an unusual approach to public space: using private philanthropy to create a destination intended for broad public use. Its story is therefore not simply about how $465 million can build a spectacular park. It is about how a former stretch of riverfront can be reimagined as a place for recreation, environmental restoration, cultural events and everyday encounters. Years after its grand opening, Gathering Place continues to carry the original idea behind its name creating a common space where the people of Tulsa can simply gather.
