Dawson Trails 


The Dawson Trails project includes property in the Dawson Ridge and Westfield Trade Center areas. The Dawson Ridge 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 PD was amended, resulting in the creation of the Dawson Ridge PD. The density and permitted uses originally established with the Castle Rock Ranch PD were carried forward to the Dawson Ridge PD zoning.

Current Zoning

Dawson Ridge Planned Development

The Dawson Ridge property consists of approximately 1,883 acres and is located west of Interstate 25, south of Territorial Road and one mile north of Tomah Road. The property was zoned for 7,900 dwelling units to include single-family detached and attached, townhomes, condominiums, apartments and patio homes. The zoning also permitted an estimated 13 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 94 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 Dawson Ridge Metropolitan Districts was executed. The Suspension Agreement contained certain Metropolitan District obligations and failure to perform would result in a suspension of the development plan. Ultimately, the suspension clause was invoked, requiring 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 PD, located north of Territorial Road and consists of approximately 339 acres. The property was included in the 1984 Bellamah Annexation and in the 1986 Castle Rock Ranch PD zoning. The Westfield Trade Center PD allows for approximately 10 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 proposed Dawson Trails Planned Development includes a rezoning of all of the Dawson Ridge PD and a portion of Westfield Trade Center PD. The applicant, Westside Investment Partners Inc., is assembling Dawson Ridge and a portion of Westfield Trade Center under their ownership. The Dawson Trails PD will establish a comprehensive vision under an integrated development plan. 

The conceptual development plan has been discussed at the neighborhood meetings held to date. The Dawson Trails conceptual plan proposes 5,850 dwelling units and approximately 3 million square feet of commercial, office, restaurant and industrial uses. Similar to the Dawson Ridge PD Plan, the non-residential 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 50% of the property would be dedicated for open space, parks and trails, with the potential for a new recreation / sports center.

Dawson Trails Planned Development Process

The Dawson Trails PD application will be reviewed by Town staff for compliance with the Town's guiding documents, the Municipal Code criteria and technical requirements. In addition, the applicant is required to hold a minimum of three neighborhood meetings; the first to be held prior to submittal of the rezoning application, and the remainder during the period and prior to the public hearings. The Dawson Trails PD will be considered in public hearings before the Planning Commission and Town Council. 

Major PD amendments require public hearings before Planning Commission and Town Council. Public testimony will be taken at the public hearings. Planning Commission will conclude their public hearing by making a recommendation to Town Council. The 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 likely include the submittal of Site Development Plans for various areas. Those would be new land-use submittals. This webpage will be updated at that time.
