Can land use authorities deny conditional use permits based on general operational concerns? Kilgore Companies v. Utah County Board of Adjustment Explained

The Utah Court of Appeals recently addressed the critical distinction between general operational concerns and specific conditional use impacts in Kilgore Companies v. Utah County Board of Adjustment, providing important guidance for land use practitioners.

Background and Facts

Kilgore Companies operated a licensed asphalt batch plant in Utah County’s mining and grazing zone. While the plant’s operations were permitted, county ordinance limited structure height to 40 feet unless approved through a conditional use permit. After successfully obtaining approval for three 100-foot silos, Kilgore applied for permission to build two additional 65-foot silos. The Utah County Board of Adjustment denied this application, finding the additional height would “degrade the public health, safety, or welfare” and “adversely affect local property values.”

Key Legal Issues

The central issue was whether the Board’s denial was supported by substantial evidence that specifically addressed the conditional use request. Under Utah County’s land use ordinance, applicants bear the burden of proof by a preponderance of evidence to demonstrate all conditional use requirements are met. However, the Board must base its decision on evidence distinguishing between impacts from the specific conditional use versus the overall permitted operation.

Court’s Analysis and Holding

The Court of Appeals affirmed the district court’s decision setting aside the Board’s denial. The court found that Kilgore satisfied its burden of proof through competent testimony demonstrating the additional height would not increase plant operations, production capacity, or secondary effects. Critically, the court noted that Kilgore could install unlimited 40-foot silos to achieve the same storage capacity, making the height restriction the only relevant consideration. The Board’s decision lacked substantial evidence because public testimony focused on general plant operations rather than the specific impact of increased silo height.

Practice Implications

This decision emphasizes that land use authorities cannot rely on general operational concerns when evaluating conditional use permits. Evidence must specifically address the requested use’s incremental impact. For practitioners, this highlights the importance of developing a clear record that distinguishes between permitted baseline operations and the specific conditional use request, ensuring administrative decisions are supported by relevant substantial evidence.
