Utah County requires an approved erosion and sediment control plan before any grading or construction activity, with Wasatch Front foothill sites facing stricter slope stabilization rules. Silt fence, wattles, and stabilized construction entrances are standard. County inspectors can halt work for uncontrolled sediment.
The Utah County Public Works Standards and the Land Use Ordinance require erosion and sediment control (ESC) on all land-disturbing activities. Sites over 1 acre must file a SWPPP under UAC R317-8 including specific BMPs. Hillside and foothill developments along the Wasatch and Lake Mountains face additional requirements under the county's sensitive lands provisions, including temporary matting on slopes over 15 percent and prompt revegetation. Stabilized construction entrances (rock pads) are required to prevent track-out onto public roads; track-out must be removed by end of day. Concrete washout containment is mandatory. Disturbed soil must be stabilized within 14 days of work stopping. Provo City Code §15.04 and Orem City Code §28-5 impose parallel rules within city limits. Inspectors from county Public Works or city engineering perform routine construction inspections.
Missing or failed erosion controls: stop-work order and fines $250 to $2,500 per day. Sediment discharge to Utah Lake tributaries or storm drains: UPDES penalties up to $10,000 per day. Track-out onto public roads: cleanup cost recovery plus citation. Failure to stabilize within 14 days: daily administrative fines.
