What Is Legacy Park?

Legacy Park is a proposed 200-acre mixed-use development at the northeast corner of Ellsworth and Williams Field roads in southeast Mesa. Led by Vestar and landholder Pacific Proving LLC, the plan blends residential, retail, hospitality, office, and public parkland into what developers call an “urban oasis.”

Is Legacy Park Approved Yet?

Not yet. The project is still in the planning stage. Over the next 18–24 months, Vestar must secure annexation into the City of Mesa, rezoning, entitlements, and finalize its development team.

What’s Included in the Plan?

• Retail & Dining: ~300,000 sq. ft. of space for shops and restaurants

• Residential: ~2,400–2,500 multifamily units

• Hospitality: A 600-room luxury resort hotel

• Office Space: ~3.4 million sq. ft. of mid-rise office and campus development

• Public Amenities: 20+ acres of parkland with trails and a man-made lake

Why Mesa?

• Strategic Location — Near Phoenix-Mesa Gateway Airport and ASU’s Polytechnic campus

• Growth Corridor — Southeast Valley is one of Arizona’s fastest-growing regions

• Regional Impact — Expected to serve Mesa, Gilbert, Queen Creek, and beyond

Who’s Behind the Project?

• Vestar: Developer known for large-scale retail and mixed-use centers across the U.S.

• Pacific Proving LLC: Landowner with ~20 years of control over the site

What’s the Timeline?

There’s no official construction start date. With annexation, entitlements, and permitting still ahead, groundbreaking likely won’t happen until late 2026 or beyond. Build-out could take a decade.

How Could This Affect Arizona’s Construction Industry?

If approved and built, Legacy Park could:

• Generate thousands of construction jobs

• Push demand for housing and infrastructure in southeast Mesa

• Add competition for skilled trades, potentially extending timelines on other projects

• Increase demand for roofing, solar-ready builds, and energy-efficient materials
