Board approves Stonewall Estate subdivision near County Road 23 with conditions

Larimer County commissioners voted 3‑0 April 20 to approve the Stonewall Estate preliminary plat, a proposed subdivision that would divide an existing roughly 19.97‑acre parcel into four single‑family lots in the RR2 rural residential zoning district.

Staff summary and record: Senior planner Samantha Mott told the board the applicant proposes three new single‑family lots plus the existing home lot, with a new 40‑foot access road along the north edge of the parcel and shared access points off County Road 23. Little Thompson Water District would supply water and each lot would use on‑site septic systems. The planning commission recommended approval by a 7‑0 vote; county staff found the application met the applicable subdivision and development standards subject to the conditions in the staff report.

Key points and conditions: Engineering and applicant representatives told the board the relocated access point to the north was selected to maximize sight distance at a curved section of CR 23 and to address fire‑district and public‑safety concerns. A road maintenance agreement will be required because the new right‑of‑way will be publicly recorded but privately maintained by the lot owners. Staff also noted a preliminary drainage analysis and geotechnical report are on file; the county will require any additional percolation or drainage certification at final plat if needed, and disclosure language will be recorded to notify future buyers of site conditions.
