Memmen Parcel Annexation

Annexation proposal

The applicant, Barbara J. Lincoln, submitted to the Town of Castle Rock a petition for annexation of unincorporated property in Douglas County, known as Memmen Parcel Annexation.

The property is located west of Ridge Road, south of Fifth Street, and north of Plum Creek Parkway. The property is approximately 5 acres. The property is surrounded by the Memmen Young Infill Planned Development.

Current zoning

This property is currently zoned in Douglas County as Agriculture One (A-1). The existing zoning on the property allows for agricultural uses, places of worship, public and private schools and single-family residential development on lots ranging from 2 to 35 acres.


The annexation petition was found to be in substantial compliance with the requirements of the Colorado Revised Statutes and the property was found to be eligible for annexation per the requirements of the Colorado Revised Statutes, and was accepted for review by the Town.

The applicant proposes to incorporate the property into the Memmen Young Infill Planned Development. A Major Amendment to the Memmen Young Infill PD has been applied for. The application proposes to zone 180.5 acres to allow for 334 detached single-family homes and 114 paired homes (228 dwelling units) for a total of 562 dwelling units.

The annexation process

Annexation proposals must follow a state-mandated process, defined in the Colorado Revised Statutes. That process begins with Town Council determining if the annexation application meets statutory requirements and is eligible to start the annexation process. Then, public hearings can begin in order to determine if the property should be annexed to the Town.

To aid in Council's decision-making, staff reviews the project and studies the potential impacts on Town roads, water and overall levels of service. Input is also gathered from other agencies such as Douglas County, local service providers, nearby Homeowners Association and the Colorado Department of Transportation. The Town requires that a minimum of three neighborhood meetings be held prior to the public hearings. The Town's goal is to ensure every application matches the community's vision and makes technical sense.

Once the review process and neighborhood outreach are complete, the applicant must go through a series of public hearings before Planning Commission and Town Council to decide if the Town will annex the property.
