Massive project could add 6,800 homes near Micron at I-84 in CBH Homes’ largest-ever development


EastboundAs the Treasure Valley begins to develop to the east, a special BoiseDev series looks at the developments and the impacts. Join us on November 12th in Boise for a special event with key stakeholders on the growth. Details and tickets here.

Inside a junior high school gym in Boise, about a dozen people gathered around poster boards and digital displays. The small gathering was a neighborhood meeting for one of the biggest housing developments ever contemplated in Ada County.

In one corner stood Corey Barton, the housing developer behind CBH Homes, who has built hundreds of projects in the Treasure Valley over the years, but this proposal would be the largest of his career.

Radiance would spread out across approximately 1,200 acres and contain more than 6,800 homes just across the freeway from Micron’s rapidly expanding campus. It would include more than twice as many homes as Harris Ranch, and rival Avimor’s 8,000+ units in size.

BoiseDev reported on an earlier version of the concept in 2025 when it was referred to as East Hollow.

Large-scale development

According to CBH Homes Land Development Manager Katie Miller, the project would also have an area-specific plan, much like Harris Ranch. Entities controlled by Dennis M. Baker and Associates currently owns much of the land.

According to maps shown at the neighborhood meeting on Oct. 1, the project calls for a mix of high-density, medium-high-density, medium-low-density, and low-density housing.

Marketing materials say it will include everything from estate lots and starter homes to townhomes and apartments. Assisted living and retirement communities are also planned.

In total, the project includes 3,782 single-family homes and 3,050 apartments. The project is split into four areas labeled Summit Radiance, Horizon Radiance, Sunrise Radiance, and Daybreak Radiance.

Approximately 460,000 square feet of commercial property is planned for Radiance. This is split between a 23.5-acre shopping center with a grocery store and two 11-acre properties for retail and office space.

There are also 53.5 acres of land dedicated to two elementary schools and one middle school. The proposed project site sits on both sides of the West Ada and Boise School Districts’ boundary line.

But each of the proposed schools is planned within the West Ada area. A library is also planned for the community.

Three acres near the project’s center are reserved for police, fire, and emergency medical services.

Radiance also calls for several roadway projects, according to materials on display at the meeting. These include rebuilding and widening Eisenman Rd. to the nearby interchange and the construction of “New Lake Hazel Offsite to Railroad Tracks.” Conceptual plans for the Lake Hazel Rd. extension show the road crossing the railroad tracks near Radiance.

The project also has nearly 300 acres of open space, approximately 95 of which are classified as “improved open space.” A 29-acre park with a community center is located toward the center of Radiance’s boundaries. Walking, biking, and nature trails are also planned.

Just outside Boise

The project is currently set to remain under Ada County jurisdiction rather than seeking annexation into the City of Boise. In a taping of the BoiseDev podcast, we asked Boise Mayor Lauren McLean about the project.

“In general, and even with this one, I think it’s best that cities be in the development space, because we are expected to have water and sewer and police and fire and all those pieces. When this is built, all those residents will think it’s in Boise. Yet the county, with their sheriff and other things, will be expected to service this,” McLean said.

McLean noted the city is studying whether it can afford to extend its limits and service areas like this in the future, but the timing of this did not match up with the Radiance developers’ own timeline for their project.

“We need homes in this region. This whole region, ideally, we’d see more homes, because there is a shortage. These are homes that are close to jobs. In an ideal world, we would be able to determine if growth could pay for growth there and then have that conversation around whether it’s more strategic to be in the City of Boise,” McLean said.

The project does not yet have an official application in with Ada County. This, plus an approval process, will need to be completed before anything in Radiance could materialize.
