New large single-family subdivision proposed for Lone Tree western mesa

Planning materials and a Castle Pines Connection story published Feb. 26, 2026 outline a new, large single-family subdivision proposed for Lone Tree’s western mesa under the name Hillcamp, also referenced in documents as Mesa Tops/Hillcamp. The materials present the project as a single-family residential development located on the mesa above Lone Tree, though the initial public summary focuses on the project name and location.

The Castle Pines Connection coverage and the planning packets published Feb. 26, 2026 use both Hillcamp and Mesa Tops/Hillcamp to identify the site, indicating developers and planners are using multiple labels for the same proposal. Those dual names appear repeatedly in the planning materials distributed alongside the local news story, tying the proposal directly to the western mesa geography that has been a focus of recent land-use discussions in Douglas County.

The planning materials describe the proposal as a large single-family subdivision; beyond that characterization, the packets provided to the public and noted in the Castle Pines Connection story emphasize conceptual components rather than finalized permits. The Feb. 26, 2026 files include maps and a project title that local planners and residents can reference when following future submissions tied to Hillcamp or Mesa Tops/Hillcamp.

Lone Tree residents who track development on the western mesa will recognize the Hillcamp/Mesa Tops labels from the Feb. 26, 2026 disclosures, which consolidate the proposal under those names in city and county planning references. The project’s appearance in planning materials and in the Castle Pines Connection story places it on the docket of local interest, even as precise counts of lots, infrastructure plans, and timing were presented only at a conceptual level in the published materials.

As the Hillcamp (Mesa Tops/Hillcamp) proposal moves beyond the Feb. 26, 2026 outline, the names used in the planning packets and in local reporting will be the primary identifiers for any future filings, neighborhood notices, or staff reports related to Lone Tree’s western mesa. Residents and property owners near the mesa can track Hillcamp and Mesa Tops/Hillcamp in upcoming planning documents to follow official filings and procedural steps tied to the subdivision proposal.
