Mesa City Council approved the Legacy Park and Gateway Crossing development agreement on September 14, moving the southeast Mesa project beyond the preliminary notice covered in our last update. The City of Mesa confirmed unanimous approval in its September 15 announcement. KTAR also reported related annexation, zoning and district actions.
Updated September 22, 2026: This report now includes the city’s official confirmation of the agreement decision. The financing terms and development commitments below come from the city’s posted council report and development agreement.

What changed from the August vote?
The August 27 action was a notice of intent to consider a tax-incentive agreement. September 14 brought the agreement decision itself. The city’s agreement item, file 26-0817, identifies Resolution No. 12571.
Our August council vote explainer documents that earlier step. The separate 7–0 figure printed beside the zoning recommendation on the September agenda refers to the Planning and Zoning Board recommendation; it should not be substituted for a council roll call.
How would infrastructure reimbursement work?
The September 14 council report estimates public infrastructure reimbursement at approximately $76.4 million, plus allowable financing costs, including 4% simple interest. The report describes a maximum reimbursement period of 30 years. That is an estimate with financing costs additional, not a $76.4 million all-in price tag.
Eligible revenue would come from taxes generated within the project: 60% of construction contracting sales tax, 45% of other sales tax, and two percentage points of the city’s 5% hotel tax. These are allocations of city tax revenue, not new tax rates for shoppers. The report says dedicated sales-tax portions remain with Mesa.
Reimbursement depends on the developer satisfying the agreement’s conditions and the project producing eligible revenue. The city report says Mesa has no obligation to cover a shortfall with other city revenues. The remaining three percentage points of hotel tax are discussed separately for tourism promotion through a developer-created nonprofit under an agreement with the city.
Minimum commitments differ from full-buildout plans
The report lists these minimum private improvements for Legacy Park:
A luxury hotel with at least 500 guest rooms.
At least 225,000 square feet of commercial space, including two qualifying restaurant pad sites.
At least 300 multifamily homes.
At least 120,000 square feet of Class A office space.
Gateway Crossing has separate minimums: two midscale hotels with at least 95 rooms each, a retailer of at least 140,000 square feet, at least two restaurants totaling 6,000 square feet, and at least 22,000 square feet of additional retail.
These minimum obligations should not be confused with larger marketing projections for eventual buildout or treated as confirmed tenant announcements.
What the agreement says about the park and lake
Public improvements described in the report include utilities, streets, a roughly 20-acre park-and-lake recreation area, at least 30 surface parking spaces for the park, and a pedestrian tunnel connecting Legacy Park, Gateway Crossing and Arizona Athletic Grounds.
The lake is limited to 10 acres. The developer must acquire groundwater rights separate from the city’s water system for the lake and park landscaping. The report excludes those water rights and related water-supply infrastructure from reimbursement and assigns ongoing maintenance of identified improvements to the developers at their expense.
What does “theme park district” mean here?
The separate Legacy Park District item, file 26-0818, concerns a roughly 428-acre special district. Its council report describes a financing and governance structure with authority to levy district transaction privilege taxes and issue revenue bonds. It says district debt is the district’s obligation, not Mesa’s.
The statutory label is not an announcement of a conventional amusement park. The report discusses the mixed-use development and Arizona Athletic Grounds. The district boundary also should not be confused with the approximately 196-acre zoning site.
When could construction and opening happen?
KTAR, citing the Phoenix Business Journal, reports an expected early-2028 construction start and an October 2029 first-phase opening. That newer reported schedule differs from the developer’s older 2027 groundbreaking target. It remains a reported expectation, not a guaranteed opening date.
The posted development agreement sets different dates for reimbursement eligibility: construction commencement by December 31, 2029; completion and required conveyance of improvements by December 31, 2034; and the luxury hotel open by December 31, 2035, subject to applicable extensions. Those contractual deadlines are not the developer’s opening schedule.
For residents of Cadence at Gateway and nearby neighborhoods, the next useful evidence will be permits, confirmed tenants, construction activity and specific access plans. We will track those milestones in the main Legacy Park guide.
