Nashville's Major League Soccer team ownership and a union-aligned group has finalized a community benefits agreement for the city's proposed soccer stadium at the fairgrounds after intense negotiations that went through Labor Day weekend.

The ownership group led by businessman John Ingram and the organization Stand Up Nashville announced a signed community benefits agreement in a joint statement Tuesday morning.

It was made hours before the Metro Council considers four pieces of legislation on final votes needed to approve the stadium project. The finalized deal, which works as a contract between the ownership and Stand Up Nashville, could be a critical step toward passage.

"This is a history making agreement for Nashville with significant commitments that reflect the diversity of the community and the need for inclusivity, “Ingram said in a statement. “Our ownership has always believed a community benefits agreement would allow our project to have the most widespread impact on the Nashville community. This is a terrific step forward for our city and its Major League Soccer team.”

The two entities had announced they had reached the "majority of terms" last week, including a minimum of $15.50 wages for workers at the stadium and a requirement that at least 20 percent of the housing stock at the project's mixed-use development be affordable housing.

But holdups remained.

The main final sticking point heading into the weekend had been whether to require so-called "high-road" contractors for construction of the stadium, favored by the union group in Stand Up Nashville, as well as other construction worker safety standards.

It appears those issues got resolved in order for the agreement to come together.

The two sides are calling the final agreement "an unprecedented commitment" in affordable housing, minority business enterprises, jobs, workplace safety, and workforce development. The agreement also provides for inclusive spaces at the stadium and community services such as a day care center.

“Stand Up Nashville took the voice of the community and brought it into the development process for the first time in Nashville’s history,” Odessa Kelly, of Stand Up Nashville, said. “This is a testament to how a coalition can bring a city together.”

Thirty council members had signed a letter last month in support of a community benefits agreement.

In a statement, Mayor David Briley, who supports the stadium project, said the agreement shows that Nashville "embraces growth and new opportunities while ensuring every resident benefits and thrives along with it."

He applauded Stand Up Nashville and the MLS team ownership "for their leadership and persistence during this process."

"It is the right thing to do for Nashville, and it will have a lasting impact ensuring our entire community will benefit from the MLS stadium development," Briley said.

"Tonight, I urge all 30 Metro Council members who signed the CBA pledge on August 7 to vote in support of the project."
