Bluffdale planning commission recommends Bridge Source precast plant site plan, grants multiple design deviations

The Bluffdale Planning Commission voted Dec. 3 to forward a favorable recommendation to the City Council for the Bridge Source precast concrete plant site plan, a large industrial facility proposed in the sand-and-gravel zone at approximately 16115 South Pony Express Road.

Staff presenter Ellen Oakman described the proposed 88,980-square-foot building on a 7.4-acre site within a larger parcel and noted the applicant has provided 48 parking stalls where 24 are required. Oakman said the applicant requested multiple deviations from the city's design standards, including reduced glazing (2% proposed vs. 15% required), limited facade articulation and roof-line variation, reduced landscaping (3% proposed vs. 15% required) and exemptions from roof-mounted screening (staff cited code 11.150.60.E and explained the sand-and-gravel zone context) (staff presentation SEG 697-760).

Jonathan Biesinger, representing the Clyde companies/Lehigh as owner, told commissioners the plant will produce large precast infrastructure elements that are delivered to customers rather than sold at retail. "This is not a public interfacing property," Biesinger said, explaining why extensive glazing and retail-facing design elements are not appropriate for the operation (applicant remarks SEG 1048-1056). He also said areas planned for hydroseeding would exceed the 15% landscaping threshold because they will be allowed to grow without irrigation; the hydroseeded areas are not in active mining zones and are part of reclamation plans.

Commissioners examined traffic, operations and environmental controls. City staff summarized the applicant's third-party traffic study and reported an estimated 216 daily trips at buildout; staff noted acceleration and deceleration lanes on Pony Express Road will be required to accommodate truck movements (SEG 1226-1231). The applicant said production could extend beyond typical business hours and described dust-control practices and maintenance of an existing dirt access road.

Several commissioners expressed concern about precedent and whether the city code should be amended for sand-and-gravel zones rather than granting many case-by-case deviations. Commissioners listed findings supporting the deviations: the sand-and-gravel zone context, distance from public sight lines and residences, operational needs for heavy equipment, thermal/sound/fire performance of precast materials, cost differentials, and the site's expected operational lifespan of several decades (discussion SEG 1400-1530). The commission moved to approve the site plan and deviations, with Commissioner Eric Swanson making the motion and the commission recording unanimous ayes; the favorable recommendation will be forwarded to the City Council for final action (motion and vote SEG 1541-1579).

Next steps and conditions: The commission approved the recommendation subject to the conditions and findings in the staff report dated 11/25/2025 and asked staff to evaluate whether a code text amendment addressing sand-and-gravel design standards is appropriate for future cases.
