Mayor Michelle Wu announced on Monday morning that Boston has signed a 10-year, public-private lease agreement with BOS Nation FC, the expansion NWSL women's soccer team, to renovate and operate out of White Stadium.

The details of the lease include the "shared usage agreement" between the team and the city regarding the splitting of field time with the soccer club, local school teams, and city residents. The mayor announced that the club will pay an annual rent starting at $400,000 (which will begin in its first full year in the stadium). It will then increase 3% annually.

Improvements to the facility, originally built in 1949, include an eight-lane track (along with new track and field features, such as shot-put and pole vault capabilities), a natural grass soccer field which Wu called "professional grade," new locker rooms and strength and conditioning facilities for school usage, and "freshly surfaced" basketball courts.

The usage for high school teams will include "end-of-season football," per the announcement.

Recent news pertaining to the public-private partnership deal Wu has championed with BOS Nation has been dominated by the growing costs of the project. After original costs were projected to be $50 million for taxpayers, the more recent estimates placed it at $91 million.

Wu has defended the costs, though she walked back remarks during a WGBH radio appearance in which she said, "We are going to pay for our half of the stadium, no matter what it costs."

After the interview, Wu clarified that there is "no such thing as a blank check when it comes to city capital projects."

BOS Nation, Wu noted, will pay for "more than half" of the reported $200 million cost of the project. (BOS Nation's ownership group includes Boston Globe Media Partners CEO Linda Pizzuti Henry.)

The team is set to take the field in 2026, when it will begin competing in the NWSL.
