120 N 12th Street
A Type 2 Participation Program Project that supports the mixed-use development through public utility and streetscape improvements.
About the Project
The Arthur, formally known as 12th and Idaho, will replace a 24,000-square-foot surface parking lot with a 420,000-square-foot, 26-story mixed-use building, including 298 residences, ground-floor retail space, and structured parking. The residential mix includes studio, one-, two-, and three-bedroom units to be rented at market rates. The project’s estimated total development costs are $140 million. The developer, 12th and Idaho LLC, plans to certify the project with Green Globes, a program with criteria that are similar to LEED certification administered by Green Building Initiative, Inc., and active in the US since 2004. 12th and Idaho Owner LLC is a joint venture between White Oak Realty Partners (“WORP”), Ponsky Capital Partners (“PCP”), and Boise-based Oppenheimer Development Corporation.
The project includes public improvements to the adjacent alley, stormwater infrastructure, construction of streetscapes and furnishings, including bike racks, street trees, and historic streetlights, and the replacement of a section of the Boise City Canal, which runs under and adjacent to the project site.
The Arthur meets the requirements of the Participation Program as approved by the CCDC Board and promotes the objectives of the Westside District Plan. Type 2 projects are scored based on ten urban design categories to encourage compact development with pedestrian-focused design. The project scored 148 points, qualifying as a Level A project.
Boise City Design Review granted its original conditional project approval in November 2021, with full approval in February 2022. The project design was reexamined and updated to ensure viability, and Boise City Design Review approved the modified design on August 25, 2022. Preliminary site work began in early November, with the CCDC Board approving the partnership at its January 2023 meeting. The project is expected to be completed in May 2025.
