CBH plans 6,800-home Radiance community near I-84 and Memory Lane

BoiseDev reports that CBH Homes is planning a massive new community called Radiance in unincorporated Ada County near Interstate 84 and Memory Lane, across the freeway from Micron. The proposal covers about 1,200 acres and could include more than 6,800 homes, but as of October 5, 2026, BoiseDev said no official application had been filed with Ada County.

What stands out to me is the scale. A project this size isn't just another subdivision. If it moves forward, it becomes its own piece of the valley, with housing, parks, schools, commercial space, and a lot of pressure on roads and services in an area that already gets a lot of attention because of Micron and south Ada growth.

What's planned

BoiseDev's project tracker says Radiance, previously called East Hollow, would sit just south of Boise city limits at I-84 and Memory Lane. The housing mix could include both single-family and multi-family homes.

Project materials cited by BoiseDev show more than just houses:

• About 6,800 homes
• Commercial areas
• School sites
• Parks and other amenities
• Nearly 300 acres of open space
• About 95 acres of improved open space
• A 29-acre park with a community center
• Walking, biking, and nature trails

BoiseDev also reported the project is currently expected to remain under Ada County jurisdiction rather than seek annexation into Boise. That's an important detail because county review, zoning expectations, and service questions can look different than they would inside city limits.

Where timing still looks uncertain

Right now, this is still early. BoiseDev reported that no official application had been filed with Ada County as of October 5, and the project still has to go through the county approval process before anything can be built.

A September 23 legal notice said Bailey Engineering, on behalf of Trilogy Development, would hold the first of two public involvement sessions for the Radiance Planned Community on October 1 at Les Bois Junior High School. The notice described that as the first of two meetings, but no date for the second session was found in the sources reviewed.

There also wasn't a construction start date in the materials reviewed. So for anyone trying to figure out whether bulldozers are about to show up, the answer is no clear timeline has been announced yet.

The bigger issue is access

For me, the road piece is the part to watch most closely. BoiseDev's earlier reporting from 2025 said access was expected from a planned future extension of Lake Hazel Road, and at the end of 2025 there was still no exact construction date or identified funding for that extension.

Other earlier BoiseDev reporting said pre-application notes envisioned Veolia serving the project and indicated a Whitney Fire District station would likely need to be built within the community.

This also overlaps with a much bigger transportation conversation. The Idaho Transportation Department says its South Ada and Canyon County Connectivity Study is looking at the area south of I-84 from SH-45 to near the Blacks Creek interchange, including future north-south connections involving Cole Road, Five Mile Road, Cloverdale, and an alignment that may connect at or near SH-16. ITD says the study was launched because of growth, congestion on SH-69, and projected growth in Kuna and the southern parts of Boise and Nampa.

My take

If you live nearby, I'd pay at least as much attention to roads, utilities, and public services as to the home count. A big number grabs headlines, but what changes daily life is how people get in and out, where school sites land, and how the project phases over time. Those details matter a lot more than the name on the sign.

If you're house-hunting in southeast Boise, Kuna, or anywhere along the south side of the freeway, I'd treat this as a long-range growth signal, not an immediate supply shift. Nothing changes overnight without a filed application, hearings, and infrastructure decisions. But if you're planning a move in the next few years, this is exactly the kind of project worth tracking because it can reshape where buyers look and where builders focus next.
