Commissioners approve conditional-use permit allowing temporary outdoor storage of five commercial vehicles on 36-acre Adams County property

The Adams County Board of County Commissioners approved a conditional-use permit (RCU2023-56) on Sept. 16 to allow the accessory outdoor parking and storage of up to five commercial vehicles on a 36-acre parcel in an Agriculture-3 (A-3) zone. The board voted 3-0 to approve the permit with 19 conditions and one staff note; the permit is valid for five years.

County staff said the application originated from a compliance action that began in August 2023 and that the applicants filed for the permit in September 2023. Because the application was submitted before Adams County adopted new outdoor vehicle-storage regulations in October 2024, staff evaluated the request under the 2023 standards then in effect. Under those older standards, accessory outdoor storage of oversized vehicles on residential agriculture parcels was allowed by conditional use.

Planner David Deboski and Planning and Development Manager Jen Rudder told commissioners the approved request is limited to five commercial vehicles, will not include any on-site vehicle maintenance or vehicle-based businesses, and will require an asphalt parking surface, fencing, and enhanced landscaping buffers. Staff recommended approval, subject to eight findings of fact and 18 conditions; during the hearing an additional condition was added requiring the property owners to reside on the site for the duration of the permit (condition 19).

Applicants Marissa and Chris Bieber (owners) and their counsel explained the request as a limited, short-term solution to address periods when vehicles are between jobs and cannot be stored at their primary commercial lot. Counsel said the owners would prefer that their equipment be working on active job sites rather than on their property. The applicants provided photographs of the site and ten letters of neighbor support; two of the nearest neighbors testified at the hearing in favor of the permit.

Key permit conditions include: a five-year permit term; installation of an asphalt parking surface for the storage area within one year; an eight-foot fence and enhanced landscape buffering around the parking area; prohibition of on-site vehicle maintenance or repair; hours limiting vehicle movement to 7 a.m.–7 p.m.; requirement to maintain spill-response materials on-site; and the new condition that the property owner(s) must reside on the property for the permit duration. County staff also noted that a drainage report will be required if the impervious surface area exceeds 3,000 square feet.

Commissioners asked staff and applicants to clarify the distinction between commercial vehicles that require the CUP and agricultural or personal vehicles that do not. County code officers and applicant counsel explained that vehicle classification is tied to state registration and to how vehicles are used: equipment legitimately registered and used for agricultural purposes may be exempt, while commercially registered construction vehicles fall under the CUP. County staff said the original enforcement case cited oversized commercial trucks on the property; the current request was narrowed to five commercial vehicles after staff and the applicant revised the submittal.

Commissioner discussion acknowledged broader county concerns about the conversion of agricultural parcels to quasi-industrial storage uses and the need for longer-term policy solutions. Commissioners said they want to limit scope creep by reviewing remaining applications and by pursuing zoning or policy changes where needed. The board’s immediate action was to approve this specific, narrowly defined request with conditions meant to limit long-term impacts.
