Weber County, UT Mobility & Curb Rules: Bike Lane Rules (2026)

Weber County's Form-Based Zone (FB), Chapter 104-22 of the county code, sets construction standards for streets built as unincorporated development occurs within the zone. Section 104-22-7.020, Specific Street Design Standards, governs curb extension bulb-outs used for traffic calming at intersections, pedestrian crossings, and mid-Block Alleys. The code states plainly that bike lane widths shall not be obstructed or made narrower at any point along a curb extension bulb-out. Bulb-out design otherwise follows County Engineer specifications, and where a bulb-out leads to a raised pedestrian crosswalk, bollards or other permanent features must be installed to keep vehicles from entering the pedestrian-way.

The same section requires bike facilities as part of required street improvements. Unless the standard is waived, a separated concrete bike lane five feet wide must be built on the same plane as the sidewalk, divided from the pedestrian walkway by the tree lane. Where topography makes that impossible, the County Engineer may instead allow a five-foot retroreflective green bike lane painted into the center of the vehicle travel lane and marked with retroreflective sharrows. Wherever angled parking is installed along the street, the code additionally requires a three-foot parking buffer between the bike lane and the curb specifically to absorb vehicle bumper overhang, and permits vegetation within that buffer strip.

These standards apply to new development within the FB zone in unincorporated Weber County; they are engineering requirements imposed on developers and reviewed by the County Engineer's design review, not day-to-day traffic rules for cyclists or drivers. The chapter's most recent amendment affecting this section was Ordinance 2023-09, adopted May 16, 2023.
