Ogden, UT Environmental Rules: Erosion Control (2026)

Article B of Ogden City Code title 9, chapter 7 requires a storm water pollution prevention permit for construction and land disturbing activity, with a full storm water pollution prevention plan (SWPPP) mandatory on sites larger than one acre under section 9-7B-2. Section 9-7B-5 sets the technical design standards. The authorized enforcement officer may adopt administrative design criteria for grading, erosion, sediment control, and watercourse crossings, and cut and fill slopes cannot exceed a two-to-one (2:1) ratio absent approval. Clearing cannot begin until sediment control devices are installed and stabilized.

Once clearing starts, soil stabilization must be completed within five days of clearing or of any inactivity in construction; if a vegetative method like seeding is used, it must establish within two weeks or the site must be reseeded or switched to a nonvegetative option. Off-site soil stockpiles must be stabilized or covered at the end of each workday, and steep slopes or drainageways require specialized stabilization techniques approved by the enforcement officer. Sediment control must include settling basins, sediment traps, and perimeter controls, plus vegetated buffer strips protecting adjacent properties.

Section 9-7B-6 separately requires that erosion, sediment, or pollutant discharge onto public or uncontrolled private property be eliminated to the maximum extent practicable, bars tracking mud or debris onto public rights of way, and requires temporary erosion controls to be removed and any exposed soil permanently stabilized within thirty days after removal. Section 9-7B-7 authorizes the enforcement officer to inspect at each construction stage, and section 9-7B-8 allows a stop work order whenever land disturbance proceeds without a permit or the SWPPP is not implemented.
