Planning commission forwards vehicle-impact protection standards to village board

The Montgomery Planning and Zoning Commission voted unanimously to forward staff recommendations to the village board on vehicle-impact protection standards for buildings and site design.

Director App., who led the presentation, said staff reviewed recently adopted rules in neighboring communities and recommends placing a standard in the Unified Development Ordinance (UDO), not the building code, because the UDO better governs site design and allows illustrations to guide developers. "We recommend going with the same impact standard as Asiggo — 5,000 pounds at 30 miles per hour — and incorporating the standards into the UDO," Director App. said. Staff said the standard would target principal public entrances, storefronts with low window sills, outdoor dining and daycare play areas adjacent to parking, and residential care facility entrances.

Staff described two model approaches: a pedestrian-focused UDO standard cited for Asiggo (5,000-lb at 30 mph, ASM F316) and a security-oriented building-code approach adopted by Sugar Grove (6,000-lb/ASCE7). The commission heard staff’s estimate that of approximately 130 commercial structures surveyed, about 35% either lacked adjacent parking or already had some form of bollard/planter protection, and that uniform retroactive requirements for existing buildings would be difficult to enforce.

Commissioners debated whether voluntary installations should be held to the same technical and aesthetic standards as new construction. One commissioner argued that if an owner elects to install protection voluntarily, it should meet the code so residents aren’t given a false sense of security. Another suggested a discretionary clause to allow the building department to require a higher-rated device in areas that mix passenger vehicles and semis.

Commissioner Wallers moved to forward staff recommendations with three additions: require voluntary installations to meet the UDO impact and design standards; require a higher 6,000-lb-rated device in industrial/semis-facing commercial zones (like Sugar Grove’s standard); and require placement that does not interfere with public underground utilities. The motion, seconded by John, passed unanimously (6–0; Commissioner Hammond absent).

The commission’s referral directs staff to draft the specific UDO text and illustrations for the village board to consider at its next available meeting; commissioners emphasized inspections and consistent enforcement as follow-up steps.
