Micron gives $2.5 million toward geothermal heat for 300-plus affordable homes in Boise's Lusk District

BOISE - Micron Technology has given $2.5 million in gap funding to the Lusk Housing District, a project meant to heat more than 300 new affordable homes with geothermal energy, the City of Boise said in an Oct. 27 release.

The development is by J. Fisher Co. in partnership with the city's Housing Land Trust Program. The city says it is the first effort by a U.S. city to use geothermal heat for multifamily affordable housing. Boise received $1 million earlier this year from the Bloomberg Philanthropies Mayors Challenge to pilot the expansion of its geothermal system.

Other funding listed in the release includes tax credits and private activity bonds through the Idaho Housing and Finance Association and investments from the city, the Capital City Development Corporation and J. Fisher Co. Ten percent of the homes are set aside for people leaving homelessness. Plans also include retail space, streetscape work and a public parking garage.

Groundbreaking is expected in spring 2027, according to the city.
