Portland Hearts of Pine unveil waterfront stadium plan, eye Championship move

Portland Hearts of Pine unveiled plans for a new soccer-specific stadium at Cassidy Point that could anchor a future move to the USL Championship. The project calls for a 9,000 to 11,000-seat venue on the Portland waterfront, with construction expected to start in 2027 and an opening target of early 2029.

The club said the stadium would cost more than $50 million and would convert an industrial coal storage site into a permanent home for its men’s and women’s teams. Hearts of Pine also said the development would preserve the site’s 600-foot pier for marine industrial uses, keeping part of Cassidy Point tied to the working waterfront while adding new recreational space around the stadium footprint.

The timing matters as much as the site. Hearts of Pine are in USL League One now, but the league has already approved a promotion-and-relegation model and describes it as a three-tier men’s professional system. USL Championship, meanwhile, says it reaches a population of more than 84 million, a scale that makes permanent stadium control and strong market support central benchmarks for any club eyeing a higher level.

Portland’s pitch leans on both. The club has been playing at Fitzpatrick Stadium in Portland, and Maine Public noted that Hearts of Pine had played three years of sold-out games there and had outgrown the venue. That is the kind of on-field demand off-field investors like to point to when they argue that a market is ready for more than a temporary home.

The Cassidy Point plan also fits a wider USL pattern. Sacramento Republic FC has broken ground on Republic Stadium, which is slated to seat more than 20,000, while Detroit City FC has moved ahead on AlumniFi Field, another stadium project tied to long-term league ambition. Orange County SC expanded Championship Soccer Stadium after a run of sellouts, a reminder that capacity and permanence remain major signals in the league’s evaluation of where clubs belong.

USL strengthened that picture on June 1, when it said five additional clubs would be included in its 2027 sanctioning application, describing those additions as part of a connected three-tier professional structure. Hearts of Pine added another piece to its footprint on June 4, when it was granted a USL W League franchise and said women’s soccer would come to Maine in 2027.

For Portland, the stadium is not just a real estate play. It is a bid to show the league that the market, the money and the building are all moving in the same direction.
