Steps to Develop Zebulon

  1. Voter Support: In 2022, voters overwhelmingly extended a sales tax measure for the Parks, Trails, Historic Resources and Open Space Fund, expected to generate over $350 million over 15 years.
  2. Public Input: During a Live Town Hall in May 2024 about the Fairgrounds Master Plan, the Board heard from a large group of parents and youth about the need for more youth sports facilities.
  3. Community Engagement: Commissioners hosted a Live Town Hall on June 27, 2024, to further explore the community’s priorities for the Parks, Trails, Historic Resources and Open Space Fund, hearing again about the need for youth sports facilities.
  4. Visioning: In early 2025, Sterling Ranch approached Douglas County with the idea for the Zebulon Sports Complex.
  5. Stakeholder Engagement: Douglas County Commissioners met with more than 10 key stakeholders on Feb. 24, 2025, including municipalities, HOAs, sports organizations and developers. During this meeting, they discussed location, land use, funding and potential partnership opportunities to meet the needs of the community and surrounding regions. Meetings like this one are open to the public and notified weekly via the Commissioners’ weekly schedule.
  6. Community Engagement: Commissioners hosted a Live Town Hall on April 14, 2025, to debut the initial vision for Zebulon. It was the county’s most-attended Live Town Hall ever, reaching more than 10,000 people online and via phone. More than 200 people attended in person.
  7. Engineering: On May 27, 2025, Douglas County Commissioners approved a contract for $325,000 with Felsburg, Holt & Ullevig (FHU) to investigate long-term and short-term roadway infrastructure needed to support the Zebulon Sports Complex. On July 22, 2025, Douglas County Commissioners entered a contract for $410,000 with engineering firm Kimley-Horn to design the land development infrastructure for the proposed site, including grading, roads and utilities (sanitary/sewer, water, electric, gas and fiber). The consultant will also estimate the costs to build the site’s land development infrastructure. 50% of the design and initial estimates for the land development and roadway infrastructure are expected in late September/early October 2025.
  8. Call for Private Partners: Douglas County will go through a competitive process to partner with private companies to design, build, finance, operate and maintain the various elements of the vision, such as an ice complex, baseball fields and an indoor sports complex.

What's Next?

  • Site: Sterling Ranch owns the proposed Zebulon site in northwest Douglas County. The two entities are negotiating an agreement. Sterling Ranch, proposed to be the private partner for building Zebulon, is now interested in just the land swap.
  • Community Engagement: When more is known about potential partners and the cost of the infrastructure, Douglas County will host additional public meetings. Sign up for updates.
  • Construction Documents: Engineering firms Kimley-Horn and FHU are designing the basic infrastructure like roads, grading and utilities. Their plans will be used to open a competitive bidding process for contractors to begin preparing the site for future building construction. A separate bidding process will follow for the actual sports facilities and other buildings, called vertical construction.
  • Public Meetings: All contracts for construction will go before the Board of Douglas County Commissioners for consideration during regularly scheduled public Business Meetings.  
  • Partner Contracts: All contracts with private partners for vertical construction and sports programming will go before the Board of Douglas County Commissioners for consideration during regularly scheduled public Business Meetings 
  • Construction: Construction on the initial grading could begin as early as fall 2025.

Site & Environmental Information

Zebulon is one piece of a larger planned development along Waterton Road in Sterling Ranch, portions of which will be County-owned and portions privately-owned.  The proposed development includes approximately 200 acres of open space, about 50 acres for the Zebulon Regional Sports Complex, and space for a new County emergency operations and training center, plus 200 acres for Sterling Ranch private development. The current planned location for Zebulon requires no remediation.

A separate portion of the Waterton Road development was formerly Chemours Louviers Site, used as a dynamite factory from 1907 to 1989. In 2022, the Colorado Department of Public Health and Environment (CDPHE) provided a letter approving prior remediation on the Waterton Road development site. Some small parcels of privately owned property remain on the Waterton Road development site that are under a deed restriction for solid waste management units, which would need to be remediated prior to construction of that area; these parcels are outside of the planned space for Zebulon. Read the letter in the Additional Materials & Resources section below.

Economic Impact

The Metro Denver Economic Development Corporation and Denver Metro Chamber of Commerce provided an Economic and Fiscal Impact Analysis on the site, which includes both Zebulon and additional private development in the area, known as The Waterton West Development, which will include 2.39 million-square feet of mixed-use development.

The report estimates that “from 2026 to 2036, the Zebulon Regional Sports Complex is expected to generate a total economic impact of $1.3 billion, including $528.4 million in labor income and support for 1,764 jobs through construction and ongoing operations.” Read the full report in the Additional Materials & Resources section below.
