Discussion Items

• Arizona Museum of Natural History Economic Redevelopment Project – The council received a comprehensive presentation from city staff and consulting partners (GNA, Jones Studio, Gallagher & Associates, Benefactor Group) outlining a vision to transform the AZMNH into a 118,000-square-foot museum integrated with a 170,000-square-foot mixed-use development including a hotel, retail, restaurant, and event spaces. Key points included:
  • Return on Investment/Impact: The museum currently attracts 175,000 visitors annually (0.7% of the valley’s potential audience), ranking 25th out of 30 peer museums nationwide. A new, purpose-built facility could increase visitation to 515,000–630,000 annually, drive economic impact (3–4× current arts/culture sector), and boost cost recovery (currently 70–80%). The project is positioned to capture growing tourism and STEM economy.
  • Community Engagement: Surveys and an in-person event engaged 650 people. Findings showed strong loyalty, desire for adult programming, more dinosaurs, immersive experiences, and deeper representation of Arizona’s indigenous heritage and regional character.
  • Architecture and Experience Design: The design, organized around “Journeys of Discovery,” uses braided storytelling themes (cosmos, earth, life, people). The building concept incorporates Arizona-inspired materials, rammed earth, canyon-like interior atrium, double-height spaces, a rooftop observatory, and indoor-outdoor connections. Councilmember Taylor emphasized that observatory views should face the mountains.
  • Funding Model: A $300 million project is envisioned with three equal legs: public investment, private commercial investment (hospitality), and private philanthropy. Case studies from the Natural History Museum of Utah and Milwaukee Public Museum were cited. Philanthropic potential in the metro area is strong (120,000 high-net-worth households; ~$3–4 billion in annual giving). The foundation has committed $760,000 over the past two years for planning.
  • Next Steps: Staff requested approval to proceed with a two-year, $6 million work program (funded by one-time city revenues) to complete an economic impact study, community outreach, fundraising capacity building, and preliminary architectural/site design (5–10% design). Council would receive formal updates each May.
• Councilmember Questions and Comments:
  • Councilmember Adams requested more case studies and suggested more frequent public updates. He supported moving forward and praised the foundation’s dedication.
  • Councilmember Taylor raised concerns about the exclusion of creationism, stating that “both theories must be represented fairly.” She also queried the source of the $6 million and asked about the foundation’s contribution. Staff replied that the funds are one-time revenues and that the foundation will be a partner.
  • Councilmember Go Forth emphasized the need to justify the price tag, asked about alternate outcomes if fundraising falls short, and requested a detailed breakdown of the $6 million. She supported the project’s ambition but noted the challenge of convincing voters.
  • Vice Mayor Summers noted the historic significance of the existing 1937 building and asked for integration into the design.
  • Mayor read a letter from Councilmember Duff expressing full support, noting the project has evolved from a $180 million concept to a $300 million mixed-use destination, and urged council to proceed.
  • Councilmembers expressed informal consensus to move forward with the two-year process.

Key Outcomes

• Council Direction: The council indicated support for proceeding with the two-year, $6 million work program for the AZMNH redevelopment project, including design development, economic impact study, and fundraising capacity building. Formal approval will be required at a future voting meeting.
• Magistrate Appointment: Following an executive session, the council unanimously voted to place Jacob Brown on a future city council agenda for appointment as city magistrate.
• Adjournment: The study session was adjourned.
