All properties are required to maintain drainage on their own property or to an approved drainage easement and to the public way. No water can find its way onto adjoining properties beyond the easement. Sloping lots will require special grading attention, including V-ditches, swales and rock/masonry walls. Slope cannot be greater than 2:1 (two horizontal to one vertical). Rock/masonry walls are required to be installed when slopes exceed 2:1.

If you are planning to add (or are required to add) a rock/masonry wall taller than 4′ to your property (whether built with rock, brick, block, masonry, concrete, railroad ties, etc.), or a wall less than 4′ tall that is holding a surcharge, a permit is required. Be aware that rock walls cannot be built in the front utility easement.

Requirements for Submitting a Permit Application for a Rock/Masonry Wall

  1. Rock/Masonry Wall Permit Application
  2. Two (2) copies of your Site Plan (see sample Site Plan diagram) showing where on the property the wall will be placed using small circles. Note the type of wall(s), height and length of wall(s) and the valuation of the project. Show how drainage will flow with arrows. Also be sure to include drawings of any structures or other items on your lot or neighboring properties that may be within the surcharge area of a wall (see surcharge information below). SURCHARGES: Any structure (or other item in the list above) within the 45 degree plane of a rock wall causes a surcharge on that wall, which may cause the failure of the wall (as shown in the second diagram above). Any wall holding a surcharge, regardless of height, will require engineering to prevent failure (see item #3).
  3. Two (2) copies of wet stamped (original stamped) engineering from a Utah State Licensed Geotechnical (Soils) Engineer.
  4. Special Inspection Agreement.
  5. If wall(s) will be constructed in a public utility easement, first obtain easement waiver from all Utilities (see Public Utility Easements) and submit copies with your permit application.

Submit application, plans, and construction detail or engineering to the Building Department at the City Office Building at 5355 West Herriman Main Streett during our office hours of 7:30 a.m. to 5:30 p.m., Monday through Friday. Remember, the office is closed on State and Federal holidays.

Plan review will take approximately 10-15 business days, after which we may call for additional information or with corrections that need to be made to your plans. After the plans have been approved, we will call or email that the permit is ready to issue. The permit fee is $94.47. Checks should be made payable to Herriman City. Payments less than $1,000 can also be made with a Visa, Mastercard or American Express.

Remember to have the Geotechnical Engineer who designed the wall or the designated special inspector to inspect the wall and submit their certification letter or report to our office for final approval. this may be submitted in person or by email at building@herriman.org. The wall permit will remain open and non-compliant until we receive this letter or special inspection report.
