Council approves Bella Mesa North plan for 525 homes after public concerns; council limits blasting near adjacent existing homes

Castle Rock Town Council approved the Bella Mesa North site development plan late Tuesday after extended public comment from residents and multiple council members’ questions about wildfire risk, potential impacts from blasting and the location of trails and buffers along the mesa edge.

The project, proposed by Cardell Homes and reviewed by town staff and the Planning Commission, covers about 293 acres and would construct 525 single‑family homes, with roughly 174 acres of open space preserved along mesa edges and gulches. The council heard more than a dozen public comments from residents of nearby Castlewood Ranch, Franktown and the town who raised concerns about blasting, drainage, trail access, wildlife habitat and evacuation during wildfire.

Why it matters: The property includes a prominent mesa edge with existing private homes and extensive open space used by the public. Residents argued that trails close to the cliff edge would erode privacy and that blasting for infrastructure risks structural damage, falling rocks and disturbance of wildlife. The developer and staff said the plan meets the 2015 Bella Mesa rezoning requirements, including setbacks established to protect mesa views and habitats, and that technical safeguards and permitting requirements are in place.

Key elements: The approved plan contains: - 525 single‑family lots across approximately 293 acres; - more than 170 acres of open space, with publicly accessible trails and multiple trailheads and a proposed public parking lot near a central park area; - required building setbacks from the mesa edge (the PDP established a minimum 300‑foot setback to structures and a 250‑foot setback to lot lines from the mesa edge; the applicant’s design places home lots beyond those limits), - landscape and vegetation buffers and a proposed soft‑surface (3‑foot) trail set back roughly 100 feet from the mesa edge in most locations, - a central roundabout and extension of Mitchell Street to provide primary access.

Public and council debate: Residents voiced multiple concerns at the meeting and prior neighborhood sessions — including potential rockfall during blasting and whether the developer would be liable for damage to existing homes, whether emergency evacuation could be hampered by high densities on the mesa side, and how trails and trailheads would be designed to protect privacy. Town staff and the fire chief told council the proposed road network and emergency planning met the town’s requirements and that the fire department had reviewed access and evacuation plans. Staff also said the development must follow local blasting regulations, which include pre‑blast surveys, licensed contractors, and mitigation measures.

Council action and modification: Facing resident concerns, council paused an initial motion and ultimately approved the site plan with an express limitation requested by council — the developer agreed (and council required) that specific lots on the southern edge abutting existing Castlewood Ranch homes will not be subject to blasting during infrastructure work and that the developer will use alternative construction methods for those lots. Council also asked staff and the developer for continued coordination on trail placement, additional screening vegetation, drainage details and wildlife mitigation.

Outcome and next steps: The motion passed unanimously after the amendment. The developer will proceed to construction‑plan review; engineering documents will show final blasting plans, grading and utilities. Staff will continue to coordinate with Colorado Parks and Wildlife and Castle Rock Fire on wildlife protections, trail setbacks and wildfire mitigation work; the developer will be responsible for pre‑blast surveys and for repair and liability associated with blasting under state and town rules if damage were to occur.

Context: The Bella Mesa North site stems from a 2015 rezoning that reduced density from earlier plan levels and added mesa setbacks designed to preserve views and limit impacts to neighboring, lower‑density properties. Council’s conditional approval seeks to balance the town’s housing needs with neighborhood protections and risk mitigation for cliff‑edge areas.
