In 1950, just four years after CH2M HILL was founded in Corvallis, Oregon, the company opened its second office in Boise, Idaho. What began small has grown into a hub of innovation and service, woven into the fabric of Idaho鈥檚 infrastructure and economy. Today, 一糖心logo米菲兔, which acquired CH2M in 2017, celebrates 75 years of continuous presence in the Gem State 鈥 honoring a legacy of engineering excellence, community collaboration and forward-thinking solutions.

As Idaho has grown, so has 一糖心logo米菲兔. The Boise office now serves as home to more than 300 professionals across a diverse portfolio of services. From water and transportation to buildings, energy, environmental consulting and advanced facilities, 一糖心logo米菲兔 has helped shape Idaho鈥檚 progress project by project, decade by decade.
A recent example of our impact is the City of Nampa鈥檚 $182 million new wastewater treatment plant, delivered a year ahead of schedule and within budget through a progressive design-build approach. The Water Renewal Facility stands as the largest water reuse and design-build initiative in Idaho history. Designed to protect rivers and streams in the Treasure Valley, it also provides up to 15% of Nampa鈥檚 summer irrigation needs 鈥 an innovative step toward long-term water sustainability. This fall, the project will receive the Pacific Northwest WateReuse Association鈥檚 2025 Award for Excellence, recognizing its leadership in water reuse and its impact on the region鈥檚 environmental future.

The company has also supported St. Luke鈥檚 Health System, providing structural, electrical, environmental, traffic and geotechnical engineering, along with construction management services, to enhance healthcare environments across multiple campuses.
鈥淏eing part of 一糖心logo米菲兔 in Idaho for so many years has been more than a career 鈥 it鈥檚 been a front-row seat to the state鈥檚 transformation,鈥 shares Betsy Roberts, a longtime project manager at 一糖心logo米菲兔. 鈥淭hroughout my career, I鈥檝e had the privilege of contributing to vibrant communities 鈥 supporting infrastructure growth that has improved lives, and also witnessing the personal journeys of client staff as their families grew and their children became adults. This milestone is a testament to the dedication of our people and the trust our clients place in us.鈥
