Minnesota United believes it will have a good problem when they open Allianz Field next spring: more fans than seats.

The stadium rising on the corner of Snelling Avenue and Interstate 94 in St. Paul’s Midway neighborhood will have a capacity of 19,400, well below the announced crowd of 23,138 the Loons had for the home opener at TCF Bank Stadium on March 17. It’s also below seven straight crowds of more than 20,000 since July.

Allianz Field has the ability to increase capacity to around 25,000, but the ownership group headed by Bill McGuire is holding off on that additional $30 million to $40 million to a stadium price tag that already has risen from $150 to $200 million in private money.

“That doesn’t mean to say that the demand remains and we begin to make financial sense of this incredible investment that they are making (and) we won’t go down that path,” United CEO Chris Wright told the Pioneer Press. “I think that we will go down that path and develop those waiting lists and we will have people that will want to be a part of this.”

United’s season-ticket base sits just south of 13,500, with plans to cap it somewhere between 14,000 and 15,000, leaving more than 4,000 seats available per game next season. On Tuesday, the club announced it sold out of more than 600 premium seats on the stadium’s west side within 11 days.

“The fact that we’ve done it is going to turn some heads,” said Wright, a longtime executive with the Timberwolves and Lynx before joining the MLS club. “Other properties in the market might look and go, ‘How have they done this?’ Really, I think it’s because we found a way to really tell the story of Allianz Field.”

A 2,100-square-foot space adjacent to their Golden Valley offices show what the experience will be like in their new home. A hologram of Wright gives an introduction, and a collection of large touchscreen TVs provides 360-degree vantage points from fans’ prospective seats. Those who have committed signed a large flag that will fly in the stadium.

The tour also shows the north side of the stadium, with a “beer hall” and a large abundance of taps, and the roof deck for large groups above it. Each will hold about 280 fans.

The outside area on the north side of the stadium includes a 1.2-acre public lawn, which won’t be available for tailgating but is envisioned as a gathering space to eat from food trucks, play pickup soccer and watch small concerts.

The new stadium, which would nearly fit within the lower bowl of TCF Bank Stadium, will have a second round of 800 premium seats go on sale in the coming days, and demand is expected to be robust.

During a March 15 meeting with diehard supporters groups before the home opener, Sean Sittnick, United’s director of sales, revealed that season tickets for supporters will decrease from $365 in 2018 to $360 in 2019 in Allianz Field if renewal deadlines are met.

Those fans, many of whom are in the Dark Clouds group, will stand in sections holding 2,850 on the south side of the stadium. The incline of those sections will be 34 degrees, believed to be the steepest in MLS, while creating a tough environment for the opposition behind the net.

Other season-ticket holders outside the supporters section will see their prices go up 5 percent to 10 percent, with areas near the halfway line seeing larger increases, Wright said.

“We are not going to grow our gross gate that much because we are downsizing,” Wright said.
