Another new arena proposal – Las Vegas Diamond Arena – has been put forward to become the home of any potential Las Vegas NBA team.

The proposed venue would be a state-of-the-art, 21,212-seat arena that could accommodate the NBA team, plus concerts and other global events.

In March, the NBA Board of Governors voted to explore Las Vegas and Seattle as potential expansion cities.

The Las Vegas Review Journal said the proposed Diamond Arena venue would feature over 18,000 parking spaces and would be within walking distance of over 20,000 hotel rooms on the Strip.

It is planned as a 21,212-seat arena, featuring a 100,000-square-foot ground-level plaza and 140,000 square feet of team and broadcast facilities.

It would be located on the south end of the Strip at the northeast corner of Las Vegas Boulevard and Four Seasons Drive, across from Mandalay Bay, according to Tom Letizia, a spokesman for the project.

He said, “This isn’t just another arena project — it’s a global stage for the NBA. The league is looking for a long-term home in Las Vegas, and this site delivers everything needed to define the future.”

The proposed project joins several others that have been put forward for Las Vegas in recent months.

MGM Resorts floated T-Mobile Arena, which has hosted the NBA’s in-season tournament, while Las Vegas Mayor Shelley is advocating a vacant downtown site near the World Market Center.

And Starr Vegas Development has unveiled plans for a $10 billion development that would include a 25,000-seat basketball and concert arena.

Starr Vegas says this campus would be built near Las Vegas Boulevard and Starr Avenue in the south valley.

Meanwhile, the Diamond Arena project would be built on 11 acres located on the site of an existing shopping center that would be demolished.

Letizia said, “The timeline right now is contingent on the NBA, with the approvals and those will be refined as the project progresses.

“The goal is to align development with the NBA’s expansion timeline. So, we’re kind of at the NBA’s mercy as far as all of that’s concerned. And I know that’s moving on a very fast track right now.”

Where an NBA team would land would ultimately be up to the ownership group, with collaboration from the county and the NBA.

Clark County spokeswoman Jennifer Cooper said. “Clark County will work closely with the NBA on locations within our jurisdiction, which includes the famous Las Vegas Strip.”

The Diamond Arena project would be unaffiliated with a casino or hospitality group, which would create more partnership opportunities for a potential NBA ownership group, according to Letizia.

Letizia added, “This stadium will be built specifically to NBA standards. The land is there. And you know what they say, location, location, location.

“I don’t think there’s any better location anywhere than where we sit right now, walking distance to 20,000-plus hotel rooms right on the fabulous Las Vegas Strip.”
