League City is pressing ahead with a sprawling 106-acre sports complex that will replace Bay Colony Park and load up the Calder–Ervin corridor with new fields, courts and trails. The site now officially carries the name Pat Hallisey Park and is being pitched as a regional hub for youth and amateur athletics. City leaders say most of the construction bill will be covered by sales-tax revenue already earmarked for amateur sports.
What's planned at the 106-acre site
According to the City of League City, the master plan reads like a sports buffet: a five-field girls softball complex and a four-field Pony-Colt baseball complex sit at the core, flanked by two full-size soccer fields. The site will also feature a nine-hole disc golf course and a 5K trail for runners and walkers who are not interested in chasing balls at all.
Racket and paddle sports get plenty of love too, with 12 pickleball courts and two tennis courts in the design. Two playgrounds are planned for younger visitors, alongside lighted parking, a maintenance facility, concession stands and restrooms. Detention ponds are built into the layout to handle stormwater, and a memorial area to recognize local victims of the "Texas Killing Fields" is also included in the city’s project documents.
Price tag, timeline and funding
The price tag has ballooned from early expectations. The project now sits at about $44 million, and construction is expected to begin in July 2026 after a registration with the Texas Department of Licensing and Regulation, with an anticipated completion date of April 2028, according to the Houston Chronicle. When the plan first cleared the city in 2020, the estimate was closer to $7 million; officials have pointed to rising demand for ballfields and design complications to explain the big jump.
Design changes and the Grand Parkway
City project documents show that a recent shift in the Grand Parkway alignment forced designers to redo parts of the plan, including reconfiguring several detention ponds and revisiting drainage modeling, which delayed the 90 percent construction document submittal, according to the City of League City. The city has also been working through land sales and access agreements with TxDOT as the highway expands, a process that has added layers of scheduling complexity, per Community Impact.
Why it's named for Pat Hallisey
The sports complex was renamed Pat Hallisey Park to honor the former mayor and longtime parks director, with city officials saying the choice reflects his decades of work on local recreation. The city transferred ownership from the Patrons of the Park Foundation, and council members publicly praised Hallisey’s role in shaping League City’s parks system, according to the Houston Chronicle.
Next steps and what residents should expect
Design work is expected to wrap up this month, with bidding and contract negotiations running through mid-May, and the city plans to pay for much of the project through a sales-tax set-aside managed by the 4B Industrial Development Corporation, local reporting says. Community Impact reported that this schedule could put the start of heavy construction in late spring to early summer, as the city continues to fine-tune access points off Ervin and Calder. Neighbors can expect public notices, traffic details and stormwater construction staging information once bids are awarded and crews get ready to roll in.
What this means for the region
If the schedule holds, Pat Hallisey Park is expected to significantly expand League City’s capacity to host tournaments and youth leagues, which could send more weekend traffic to nearby hotels and restaurants. The project’s long road through city government, including its naming and early plans, was covered in the initial announcement and renaming reported last year.
