Logan, UT Environmental Rules: Erosion Control (2026)

Logan Municipal Code § 13.14.260 requires the applicant to prepare a sediment and erosion control plan for all construction activities regulated by chapter 13.14. The plan has to describe the potential for soil erosion and sedimentation from the land disturbing activity and explain and illustrate the control measures. Its length and complexity scale with the size of the project, the severity of the site condition and the potential for off site damage. A registered professional engineer licensed in Utah certifies the plan unless the city engineer decides certification is unnecessary because of the simplicity or common nature of the plan. The plan must also follow the BMP manual.

The code lists 17 minimum contents, among them a project description, a topographic map with contour intervals, existing drainageways and floodplains, tree protection measures, limits of clearing, grading and filling, flows leaving the site during and after construction, the projected sequence of work, detailed drawings of temporary and permanent stabilization, a maintenance schedule, and details for rock pads, wash down pads and settling basins. Mud and debris on public streets must be removed by the end of the workday by machine, broom or shovel as a minimum, and the city engineer can order more frequent cleaning.

The plan feeds the permit. Under § 13.14.090 a land disturbance permit from the city engineer is required for activity that disturbs one or more acres, for smaller activity that is part of a larger common plan affecting one or more acre, and for any smaller activity the city engineer finds poses a unique threat. Section 13.14.110 bars a building permit until the land disturbance permit is obtained. The city engineer answers a complete application within fifteen (15) days (§ 13.14.140). A permit expires if substantial work has not begun within 180 calendar days or is not complete within 18 months, and an extension for good cause cannot exceed six months (§ 13.14.150). The applicant gives the city engineer ten working days notice before construction starts (§ 13.14.160).
