Taylorsville, UT Environmental Rules: Stormwater Management (2026)

Chapter 17.05 gives Taylorsville's City Engineer authority over stormwater discharges under section 17.05.010, including reviewing and approving stormwater plans for subdivisions and commercial developments, issuing and suspending discharge permits, and regulating what may enter the City's municipal separate storm sewer system, the MS4. Section 17.05.030 requires a state UPDES stormwater permit from the Utah Division of Water Quality for any land-disturbing activity of one acre or more, or for a smaller disturbance that is part of a larger common plan of development reaching one acre.

Section 17.05.040 layers a separate City land disturbance permit on top of that state permit, triggered at the same one-acre threshold, and also required regardless of acreage for borrow pits, single-family home construction, processing of earthen materials such as topsoil and gravel screening, and parking lot construction, or for any smaller disturbance the City Engineer decides poses a unique threat to water quality, air quality, or public health. Section 17.05.070 backs the permit requirement with a hold on the building permit itself: no building permit issues until the applicant has satisfied Title 17's requirements, subject to listed exceptions such as emergency work.

Best management practices are defined by reference to Salt Lake County's stormwater guidance document rather than a separate Taylorsville manual, and maintenance agreements for private stormwater facilities are recorded with the Salt Lake County Recorder.
