Commission approves 16,500-square-foot addition at 1450 Hoff Industrial Drive

The O'Fallon Planning and Zoning Commission on July 2 approved a site-plan renewal allowing a 16,500-square-foot addition to the Blum International facility at 1450 Hoff Industrial Drive. Staff said the plan was substantially unchanged from a May 2025 approval but had expired before construction began, prompting the renewal request.

Dan Bax, an engineer for the applicant, told commissioners the addition will sit off Industrial Drive near exit 216 by the Fred Weber Quarry and that the site remains zoned I-2. "We're requesting site plan approval for a 16,500 foot addition," Bax said, noting the building will match existing exterior elevations and reach about 24 feet in height. He said the project meets parking requirements with 26 spaces where 21 are required and that regional detention already on site means no new stormwater facility is needed.

Bax said a design change was made after the original approval when relocating an Amarin line proved cost-prohibitive; the team instead added a retaining wall kept at a 10-foot offset from the property edge. Staff recommended approval with two conditions: provide details and screening for rooftop HVAC equipment and submit retaining-wall design details and calculations.

Vice chairperson Nunnery moved to approve staff recommendations; the motion was seconded and, after votes were cast and closed, the chair announced the motion carried. The approval renews the prior site plan with the listed conditions and allows the applicant to proceed toward construction once the conditions are satisfied.

The commission did not read individual roll-call votes during the meeting; the chair closed voting and stated the motion carried. The commission moved on to other agenda items after the approval.
