Davis County, UT Environmental Rules: Erosion Control (2026)

080 requires any person or business disturbing one acre or more to get a General Construction County Storm Water Permit from the Public Works Department, and bars the Department from granting one for a site that size without first approving a Storm Water Pollution Prevention Plan (SWPPP). The applicant must also separately obtain a General Construction Storm Water Permit from the Utah Division of Water Quality, post a faithful performance bond or letter of credit sized to cover improvement, maintenance and inspection costs, and pay a review fee scaled to the acreage disturbed, due before any building permit issues.

Emergency work and existing nursery or agricultural operations are exempt from the acre-or-more permit. The Department can waive the SWPPP requirement in whole or part if the project will not impair the ordinance's goals, if an alternative plan is already approved, or if site conditions make the standard plan infeasible, but only if the waiver will not degrade downstream culverts, habitat, streambanks or flood capacity. 100 layers on design criteria: the plan must address topography, drainage area, water table depth and slope, and every storm water facility needs a recorded maintenance agreement and easement, enforceable against the responsible party.

060 bans tracking mud onto public streets, washing out concrete trucks outside designated areas, and stockpiling fill, sand, gravel or mulch in the street or gutter without Public Works pre-approval.
