Creekside Innovation Park is set to redefine the industrial landscape of Thornton, Colorado’s rapidly expanding North I-25 submarket. Strategically positioned at the southwest corner of 148th Avenue and Washington Street, this Class A development delivers modern, flexible employment space to one of the state’s fastest-growing communities — offering the connectivity, functionality, and value today’s industrial users demand.

Now 50% pre-leased before breaking ground, Creekside Innovation Park is anchored by Design Mechanical, a leading national mechanical systems contractor and subsidiary of Comfort Systems USA (NYSE: FIX) — one of the nation’s largest specialty contractors with over $9 billion in annual revenue and a record $12 billion contracted backlog. Design Mechanical has committed to the entirety of Building 1 under a 10-year lease commencing upon delivery, providing a durable, investment-grade income stream that materially de-risks the project ahead of construction.

Designed as a two-building campus totaling 252,340 square feet across approximately 22 acres, Creekside Innovation Park is built to institutional-grade specifications throughout. Building 1 features 129,140 SF, while Building 2 offers 123,200 SF with 19 dedicated trailer stalls and remains available for lease or user sale. Both buildings deliver 32′ clear heights, 50′ × 52′ column spacing, 130′ truck courtyards, 4,000-amp power service, and 1.2/1,000 parking ratios — a configuration purpose-built to serve light manufacturing, aerospace, distribution, and research-and-development users.

The project reflects a multi-year planning effort by OCC Industrial in close collaboration with the City of Thornton. In January 2026, Thornton City Council unanimously approved the rezoning from Regional Commercial to Business Park, alongside the conceptual site plan — clearing the way for a thoughtfully designed park that preserves an existing creek corridor and integrates a regional trail connection along Washington Street. The result is a development that prioritizes both functional industrial performance and the long-term character of the surrounding community.

Beyond its design, Creekside Innovation Park offers a distinct economic advantage: it carries the lowest mill levy of any newly constructed development in the North Submarket, generating an estimated tax savings of roughly $2.00 per square foot annually compared to competing projects. The site also sits within a designated Colorado Enterprise Zone, providing additional incentive opportunities for qualifying tenants.

With immediate access to I-25 and E-470, proximity to Denver International Airport, Downtown Denver, Boulder, and Golden, and direct adjacency to major retail hubs including Orchard Town Center, The Grove, and Denver Premium Outlets, Creekside Innovation Park is positioned at the heart of one of Colorado’s most dynamic growth corridors. As Thornton continues its trajectory toward becoming the state’s fifth-largest city, Creekside stands as a forward-looking platform for businesses seeking modern industrial space, regional reach, and enduring value.

OCC Industrial is scheduled to deliver Creekside Innovation Park in summer 2027. Building 2 is 123,300 SF now available — contact Tyler Smith at Cushman & Wakefield to learn more.
