Summary
Lehi requires a grading permit before disturbing more than one acre of land or moving more than two feet of fill or cut, and every permit application must map erosion and sedimentation control devices such as sediment fences and basins built before land-disturbing work begins.
A map of the subject area showing the location and type of erosion and sedimentation control devices. Some erosion is unavoidable. The resulting sediment must be trapped on the site, even during design flood conditions. Construct sediment fences and sediment traps and basins before other land-disturbing activities occur. Sediment fences, traps, and basins must be properly maintained, regularly inspected, and cleaned as necessary.

Violations & Fines
Work not performed in compliance with the SWPPP plan is a grading permit violation (Section 12-B.080.G), as is grading outside the approved surveyed area, removal of survey stakes, or hauling off approved routes. Grading without a valid permit or after a permit expires draws a minimum daily fine of $500 per day (Section 12-B.090.D), and repeated out-of-bounds grading triggers escalating stop-work orders, a 30-day grading ban, and eventual permit revocation requiring a new permit fee and bond (Section 12-B.090.A). Violations may also be charged as a misdemeanor under Section 34.010 (Section 12-B.090.E).
