Planning commission continues conditional-use review for 4463 Old Ranch Road after flood concerns

Snyderville Basin Planning Commission on Feb. 25, 2025 continued consideration of a conditional-use permit for a 2,338-square-foot major accessory building proposed at 4463 Old Ranch Road after public testimony raised questions about past flooding and whether conditions tied to the CUP could address downstream flood risk.

County planner Maddie opened staff’s presentation, describing the accessory building’s floor plan and noting conditions of approval that would require a floodplain permit and final runoff calculations as part of building-permit review. “Staff recommends that the planning commission review the proposed conditional use permit, conduct a public hearing, and vote to approve the application pursuant to the findings of fact, conclusions of law, and conditions of approval found in the staff report,” Maddie told commissioners.

Brandon Brady, a floodplain manager in the county engineering department, explained why a floodplain permit is required. “Any development that happens within the flood plain triggers a floodplain report,” Brady said, adding that applicants must provide a hydraulic study showing the 100-year (1% annual chance) high-water mark and generally elevate habitable structures at least one foot above that mark. He said county review enforces those standards and requires design elements for culverts and bridges to account for the 100-year event and debris; the county requires two feet of freeboard above the 100-year storm for bridges and culverts.

Several members of the Ranch Place homeowners association testified that their neighborhood was heavily impacted in 2023. Doug Ogilvy, Ranch Place HOA manager, said the subdivision was inundated and that an undersized culvert and limited freeboard contributed to the impacts. “Our request is can we add a condition in that they extend the flood protection all the way to their north property line,” Ogilvy said, urging the commission to require the property owner to move protective measures to the property line to keep water in its channel.

An attorney for the property owner, Lauren Bolger, countered that the accessory building at issue was not present in 2023 and therefore did not cause the prior flood. Bolger asked commissioners to consider that mitigation tied to floodplain engineering is usually addressed in the floodplain development-permit process. “This building wasn’t there in 2023. It didn’t cause a flood,” she said, and expressed willingness to go through the floodplain-permit review.

Commissioners debated whether a conditional-use permit could include conditions addressing the downstream concerns. A county legal citation was read to the commission during the discussion: Utah Code 17-27a-506(2) directs that a land use authority may impose reasonable conditions that “reasonably relate to mitigating the anticipated detrimental effects of the proposed use.” Commissioners noted the distinction between impacts caused by the proposed structure and preexisting flooding on the parcel.

Given remaining uncertainty about whether the proposed accessory building would create or exacerbate detrimental effects and to allow the applicant time to respond to neighborhood concerns, Commissioner Nagy moved to continue the item to the commission’s next meeting. The motion was seconded (second not specified in the record) and carried; the commission continued the item to March 11, 2025.

The continuation leaves the application pending. Staff and the commission identified the floodplain development-permit process, the engineering hydraulic report and elevation requirements, and any corrective actions to culverts or channels as the technical path for resolving many of the neighborhood’s concerns. The commission did not adopt the HOA’s requested condition to require a berm or extension of flood protection to the north property line at this hearing.

The commission’s decision is procedural: the CUP remains under review and will return to the Snyderville Basin Planning Commission on March 11, 2025 for further consideration or action.
