Board upholds director's determination requiring driveway access and emergency-turnaround for Benedict parcel at 8295 Overland Road

The Boulder County Board of County Commissioners on Feb. 4 upheld the director’s determination that a proposed change in use at 8295 Overland Road must comply with the county’s multimodal transportation standards (MMTS), including physical vehicle access and an emergency vehicle turnaround.

Amber Knotts of Community Planning and Permitting (CP&P) presented SPR-24-0075, describing a proposal to convert an accessory structure and office into a single-unit dwelling on a parcel zoned Forestry and 36.33 acres in size. Knotts said the director’s determination (issued Nov. 26, 2024) conditionally approved the change in use but required compliance with MMTS access and an emergency-turnaround. The applicants appealed that determination on Dec. 10, 2024, objecting to requirements to extend driveway access from adjacent 8297 Overland Road to the eastern boundary of the subject parcel and to install an emergency vehicle turnaround.

Knotts told the board the shared parking area and driveway located at 8297 Overland Road currently ends 35 feet east of the subject parcel’s eastern boundary and that the distance from the shared parking to the rear of the proposed residence exceeded 150 feet. She said Section 2.6 of the MMTS requires both legal and physical access by road or driveway for development and that the site-plan standard (Article 4806 A3) requires that proposed buildings not impose an undue burden on public services infrastructure. "The emergency access turnaround must be located a minimum of 50 feet from the front of the residence, and no greater than 150 feet from the rear of the residence, with a minimum 30-foot centerline radius," Knotts said.

Property owner Audrey Benedict and architect Ed Shore addressed the board. Benedict described the site’s history, a conservation easement held by The Nature Conservancy, and the family’s long-term stewardship of the property. She said an existing parking area and improved route across a meadow provide access and that Left Hand Fire Protection District has maintained protection plans for the residence since 1985. Benedict said she has undertaken restoration and mitigation work on the site and paid for a new septic system, which she described as nearly $70,000.

Ed Shore, representing the applicants, said the subdivision that created separate tax parcels followed county direction and that the Nature Conservancy amended the easement to permit conversion to a residence while keeping restrictions preventing sale or further subdivision. Shore said the county previously allowed an "informal turnaround" in the meadow to serve a permitted garage on the neighboring parcel and requested similar flexibility for the residence conversion.

Ron Lehi, Boulder County chief building official, told commissioners that exterior materials do not need to be replaced under the building code and that the structure’s exterior is acceptable as-is; he said the sprinkler requirement would be assessed during the building-permit review and currently appears to be triggered.

Chris O'Brien, chief of Left Hand Fire Protection District, said the district has protected the property since 1985 and that crews have plans to respond to both the cottage and the primary residence. "Given the nature of the separation between the cottage and the parking area, we're already set to protect the cottage as it stands because we were set to protect it as it stood as an office," O'Brien told the board, adding that crews have used the access and water sources on the parcel for firefighting.

Ian Brighton of CP&P Access and Engineering advised commissioners that if the building is a dwelling occupied full-time an emergency turnaround and full compliance with the residential access standards are required. "The distances do come into play, the 150 from the rear of the residence, and the fit no closer than 50 feet from the front of the residence," Brighton said. He said turnaround placement can be proposed anywhere within the required window and still meet standards if it complies with the dimensions.

Following public testimony and staff responses, a commissioner moved to uphold the director’s determination; the board voted unanimously to do so. In deliberations commissioners noted both the property’s unique conservation context and the MMTS public-safety purpose. One commissioner said that although the fire district believes it can serve the parcel, the board must ensure consistent application of access standards countywide. The decision requires the applicants to meet access and emergency-turnaround standards set out in the director’s determination before converting the accessory structure to a residence.

Staff recommended and the board confirmed that applicants and county staff could work to identify options that meet the MMTS standards while minimizing impacts to the meadow and viewshed. The planning docket record will reflect that the director’s determination was upheld and that required access improvements remain a condition for the change in use.
