Greater Boise Auditorium District Secures Second Downtown Idaho Parcel, Assembling Nearly Six Acres for Boise Centre Expansion
The Greater Boise Auditorium District has secured an option on a second downtown Boise, Idaho property, assembling nearly six acres along the Boise River as the district positions itself for a major expansion of its convention and event facilities. The district’s board approved an Option Agreement on April 28 for a 1.84-acre parcel at 970 W. River Street, located at the northeast corner of 9th and River streets in downtown Boise.
Background: A District Built by Boise Voters
The Greater Boise Auditorium District was created by Boise voters in 1959 and completed construction of Boise Centre in 1990. Decades later, the district is now making its most ambitious land move in recent memory, assembling a contiguous downtown footprint that officials say will serve the community well into the future.
The April 28 board action follows a Purchase and Sale Agreement approved in late March for an adjacent parcel at 11th and River streets — specifically the properties at 1050 W. River Street and 504 S. 11th Street. That parcel spans 4.13 acres and approximately 180,000 square feet, while the newly optioned 9th and River parcel adds another 1.84 acres and roughly 80,542 square feet. Combined, the two properties give the district a contiguous block of land large enough to support significant future development.
Financial Terms and Total Investment
The financial commitment involved in the two-parcel strategy is substantial. The 11th and River parcel carries a purchase price of $23.25 million. The newly approved option agreement for the 9th and River property requires a $2.5 million payment due at closing within 60 days. Should the district choose to exercise its purchase option — available at five years or later — an additional $12.5 million would be due.
Taken together, the district’s total potential outlay for both properties exceeds $38 million, according to figures provided by the district. The scale of the investment signals that Boise Centre’s leadership is taking a long-term view of the facility’s role in downtown Boise’s economic and civic life.
Board Chair Kristin Muchow framed the acquisitions as foundational to both the district’s future and the broader downtown corridor. “We’re focused on building a solid foundation for both the District and greater downtown Boise that will withstand needs well into the future,” Muchow said in public remarks reported by the Idaho Business Review. “This allows us to move forward and evaluate the best use of the land to serve our community and deliver economic impact to benefit the city.”
What the Second Parcel Adds
Beyond raw acreage, the second parcel is expected to give planners more flexibility in how the combined site is ultimately configured. Potential uses cited by district officials include additional parking and improved pedestrian access — both critical factors for a convention and events facility operating in a dense urban environment.
Boise Centre Executive Director Cody Lund emphasized that the combined footprint opens up development possibilities that a single parcel would not have allowed. “This second parcel of land opens up more possibilities in how we could develop the new site for flow and activation of the space, which are important elements as we think about how this investment fits in with our existing facility and the rest of our downtown neighbors,” Lund said in remarks reported by the Idaho Business Review.
The district’s expansion ambitions come as downtown Boise continues to attract significant public and private investment. Boise State University’s 10-year campus plan also calls for major improvements along the Treasure Valley’s urban core, including Greenbelt upgrades and new facilities — signaling broad momentum for civic and institutional growth in the area. Meanwhile, infrastructure and development challenges in other parts of Ada County, including utility capacity concerns that slowed growth in Meridian, underscore how critical careful land and resource planning is for fast-growing Idaho communities.
What Comes Next for the Boise Centre Expansion
No development design or construction timeline has been established for the site. District officials indicated that by early summer, pending the completion of due diligence, they plan to issue a request for proposals for a design team to begin exploring site configuration options for the combined parcels.
Ada County residents and Boise taxpayers interested in following the project’s progress can monitor Greater Boise Auditorium District board meetings, where major decisions on design contracts, development concepts, and financial commitments are expected to be taken up in the months ahead. The district’s use of hotel room tax revenue — rather than direct property taxes — to fund operations and capital projects is a structure worth watching as the total investment approaches and potentially exceeds the $38 million threshold.
For those tracking downtown Boise’s development pipeline, the Boise Centre expansion represents one of the largest publicly driven land acquisitions in the city’s recent history, with implications for tourism, hospitality, small business activity, and the long-term character of the riverfront corridor.
