Dawson Trails 


The proposed Dawson Trails project includes a rezoning of a portion of the Dawson Ridge Planned Development and a portion of Westfield Trade Center Planned Development. Learn more about the proposal. The applicant, Westside Investment Partners Inc., is assembling Dawson Ridge and a portion of Westfield Trade Center under their ownership. The Dawson Trails Planned Development Plan would establish a comprehensive vision under an integrated development plan. 

The conceptual development plan has been discussed at the five neighborhood meetings held to date. The Dawson Trails conceptual plan proposes 5,850 dwelling units and approximately 3.2 million square feet of commercial, office, restaurant and industrial uses. Similar to the original plan, the nonresidential uses are concentrated in a corridor just west of Interstate 25. The high-density, mixed-use development would be located in proximity to the planned Crystal Valley interchange, while the single-family homes would be located in the center, west and south areas of the property. The proposal also includes buffer areas along the north, west and southern edges of the proposed residential neighborhoods. Over 47% of the property would be dedicated for open space, parks and trails.


The Dawson Trails proposal includes property in the Dawson Ridge and Westfield Trade Center areas. The property was annexed into the Town of Castle Rock as the Bellamah Annexation on Nov. 15, 1984. Dawson Ridge was originally zoned as part of the Castle Rock Ranch Planned Development, which included the Westfield Trade Center, north of Territorial Road, and Dawson Ridge, south of Territorial Road. In 1986, the Castle Rock Ranch Planned Development was amended, resulting in the creation of the Dawson Ridge and Westfield Trade Center planned developments.

Current zoning

Dawson Ridge Planned Development

The Dawson Ridge property consists of 1,883 acres and is located west of Interstate 25, south of Territorial Road and 1 mile north of Tomah Road. The property is zoned for 7,900 dwelling units to include single-family detached and attached, townhomes, condominiums, apartments and patio homes. The zoning also permits an estimated 9.3 million square feet of commercial, office and retail uses.     

In the late 1980s, the interior roadways were platted and constructed, and a site plan for the first residential neighborhood was approved for 234 homes. Water, sanitary and storm-sewer systems were constructed. Before building construction could begin, the project stalled, and bankruptcy measures ensued. In 1992, a suspension agreement between the Town and the Dawson Ridge Metropolitan Districts was executed. That agreement required the property owner to submit a development plan to the Town for review and approval before moving forward with any new development.

Westfield Trade Center Planned Development

The Westfield Trade Center property, located north of Territorial Road, consists of 378 acres. The property was included in the 1984 Bellamah Annexation and in the 1986 Castle Rock Ranch zoning. The Westfield Trade Center Planned Development allows for approximately 11.7 million square feet of commercial and light industrial uses, including research and development facilities. Residential uses are not permitted. The zoning is still in place and has not been suspended. 

The Dawson Trails proposal covers only a portion of the Westfield Trade Center area.

Dawson Trails Planned Development process

The Dawson Trails Planned Development Plan has been reviewed by Town staff for compliance with the Town's guiding documents, Municipal Code criteria and technical requirements. In addition, the applicant was required to hold a minimum of three neighborhood meetings. Five neighborhood meetings were held. The development plan that was presented at the fifth neighborhood meeting on June 27 will be presented to Planning Commission on Aug. 11 and Town Council on Aug. 16. 

Public testimony will be taken at these meetings. Planning Commission will conclude its public hearing by making a recommendation to Town Council. Council is the decision-making authority and may approve, approve with conditions or deny the application.

If the Dawson Trails Planned Development is approved, the developer's next steps would be to submit site development plans for the various phases of development.
