Mesa, Arizona is preparing to welcome one of the East Valley’s largest master-planned developments: Legacy Park, a multi-billion-dollar project set to redefine the region’s growth corridor.
The project will span nearly 200 acres at the intersection of Mesa, Gilbert, and Queen Creek—just minutes from Phoenix-Mesa Gateway Airport and State Route 24—positioning it as a future gateway destination for the East Valley.
The site’s location is directly correlated with the fastest-growing corridor in the metro Phoenix market, offering easy access for future tenants, office users, travelers, and consumers.
What Legacy Park Will Bring
When completed, Legacy Park will introduce a dynamic combination of residential, commercial, corporate, and entertainment space. Prominent features include:
Retail and Dining: 300,000 square feet of upscale shops and celebrity-chef restaurants, including several regional firsts.
Corporate Campus: Approximately 3.4 million square feet of mid-rise office space to draw in international employers.
Residential: About 2,500 multifamily units to meet growing housing demand in Mesa’s booming southeast.
Hospitality: 600-room resort hotel luxury created by The Athens Group with meeting, event, and wedding facilities.
Public Realm: More than 20 acres of public parkland with a central lake as its anchor, with trails, green areas, and recreation.
Developers Behind the Vision
The development is being designed and built by Vestar, a Phoenix-based retail and mixed-use developer, in partnership with Pacific Proving, LLC, the landowner. Athens Group will be building the hotel component. As a team, the group sees a 20-year build-out, which positions Legacy Park as a generational investment in the economic and cultural life of the East Valley.
Legacy Park is part of a growing national wave of mega mixed-use projects that combine housing, offices, retail, and hospitality into integrated destinations. A leading example is the $5 billion One Beverly Hills development in California, which is transforming one of Los Angeles County’s most iconic corridors. Together, these projects highlight how U.S. cities are reimagining growth at a scale that blends commerce, lifestyle, and tourism.
Phasing and Timeline
Groundbreaking is expected in 2027
Phase One will consist of major retail and restaurant, about 700 units residential, first office, and the resort hotel.
Build-out is expected to occur in 20 years, ultimately being a $2 billion investment in Mesa.
Economic Impact
$56 billion economic output over 20 years.
More than 20,000 jobs created during and after construction.
A major new source of tax revenue to pay for public services such as police, fire, schools, and airport infrastructure.
Why It Matters
For Mesa, Legacy Park marks the next stage in its evolution from a suburban city to a regional hub for commerce, lifestyle, and tourism. The plan combines housing, corporate office space, shopping, hospitality, and open space to create a true live-work-play environment—an integrated destination that could redefine the East Valley for generations to come.
