Saratoga Springs planners recommend update to retaining-wall rules to match 2021 building codes

The Saratoga Springs Planning Commission on April 24 voted to forward a recommendation to City Council approving amendments to Title 19 of the city's Land Development Code that clarify construction and measurement rules for retaining walls.

Planner Sam Stout told the commission the amendment "is first and foremost, to, comply with it's the 2021 IBC and IRC building standards as well as the state of Utah, amendments that they made." He said the change requires a building permit for retaining walls "4 feet or taller in height of unbalanced fill or for any wall supporting surcharge loads," and clarifies that when a fence is built on or adjacent to a retaining wall the measurement will be taken "from ground level to the top of the fence."

Commissioners asked for definitions and implementation details. Commissioner Mann asked, "I'm wondering if you can define what unbalanced fill and what, supporting surcharge load would be." Stout said he had consulted the city building official and described surcharge loads as situations where a retaining wall supports additional loads such as adjacent slopes; he summarized unbalanced fill as when a wall is not built on a "steady surface" and there are grade/elevation differences. Stout noted the city attorney could add further legal detail.

Commissioner Miles asked whether the change takes effect immediately. Stout and the chair clarified that the commission's action forwards a recommendation to council; once council adopts the code amendment it becomes part of the code.

After discussion the commission moved, seconded and voted to forward the amendment recommendation to City Council. The motion passed with all commissioners voting in favor.

The amendment is procedural and clarifying in nature: staff said it does not change substantive site layout, setbacks or landscaping requirements but aligns local measuring and permit thresholds with the 2021 International Building Code and International Residential Code and the state's building-code amendments. The city building official, Caleb Fishnick, was cited by staff as a source for technical clarification; the city attorney was noted as available to provide legal precision on definitions.

The planning commission record does not include a detailed list of defined thresholds beyond the text described at the hearing; the staff report and the proposed ordinance language forwarded to council should contain the formal definitions and the exact code text.
