PARK CITY, Utah — After a lengthy period of planning and community feedback, Park City has chosen Brinshore Development as its partner to develop the long-discussed Bonanza Park 5-acre site, moving forward with plans to create a mixed-use neighborhood that includes affordable housing, cultural space, and neighborhood-scale retail.

The City Council selected Brinshore through a process that considered one other developer at the public interview stage of the process after the city revised a request for proposals in May. In a press release, the city emphasized Brinshore’s alignment with community goals, public input, and the ability to deliver complex mixed-use projects. City officials say the decision marks a major step toward realizing a walkable, transit-connected district in the geographic heart of Park City.

“This is a significant moment for Park City,” said Mayor Nann Worel. “With the Brinshore team on board, we are excited to move from public engagement and feasibility into design and construction. This project represents a major investment in housing, culture, and the vitality of our local neighborhoods.”

Brinshore is a Chicago-area firm with recent experience delivering affordable housing projects in Salt Lake City. The city turned down a joint proposal from Utah-based firms Woodbury Corporation and Pinnacle Real Estate Development, whose portfolio includes the University of Utah Research Park and The Meadows, a shopping  area in American Fork.

Although final designs are still in development, the vision for the site, shaped by the Bonanza Park Small Area Plan, includes affordable and mixed-income housing, a future home for the Kimball Art Center, commercial spaces for local businesses, underground parking, and new public gathering areas. Officials say trails and transit access will make the new neighborhood a model for walkability and sustainability.

The plan, shaped by input from over 1,500 residents and adopted by the City Council in July 2024 included a key recommendation to create new zoning to update and replace outdated and more commercial and auto-driven zoning. The Bonanza Park Mixed Use Zoning District encourages a mix of uses and provides a path toward increasing building heights to 45 feet through the addition of a density bonus, which allows for extra height when developers provide certain community benefits.

Now, the City and Brinshore, a nationally known firm with a focus on affordable and mixed-income developments, will enter into an Exclusive Negotiating Agreement. This step will be followed by a pre-development agreement that will establish a timeline, design milestones, and public benefits. The next phase of the process will focus on architectural plans, density, and neighborhood layout.

Brinshore is already familiar with the region. The firm recently led two major mixed-use projects in Salt Lake City: The Aster, which features 168 affordable apartments and retail space, and SPARK!, a $99 million project with 200 housing units and an on-site childcare center.

The development team also includes GTS Development Services, a Utah-based firm with deep ties to the project site. GTS previously worked on planning efforts for the 5-acre parcel and brings local experience in public-private development.

City officials say they will continue engaging the public as the project moves forward, building on years of community input to guide the final design.
