Weber County, UT Landscaping Rules: Tree Trimming (2026)

Chapter 104-22 of the Weber County Code, the Form-Based Zone (FB), requires a street tree plan as part of every new development's street improvements, and Section 104-22-7.020's tree maintenance provision sets the ongoing clearance standard once those trees are established. The code states that trees shall be pruned in a manner that gives at least a seven foot clearance above the sidewalk and a 12 foot clearance above a bike lane or parking area. The same paragraph assigns responsibility: unless an association, district, or other collective funding and maintenance entity has been approved by the county to handle tree upkeep, the street tree must be maintained by the owner or proprietor of the property immediately adjacent to the right-of-way where the tree stands. New development must also submit a tree maintenance plan as part of development review, tied to the street tree plan required earlier in the same section.

That earlier planting standard, found in the same section, requires the street tree plan to be certified by a licensed arborist or landscape architect confirming the chosen species suits the site and local climate, bars planting any street tree inside the clear-view triangle defined at Section 108-7-7, and requires tree species to be approved by the Planning Division Director and County Engineer. Street trees must also be watered through a permanent underground irrigation system installed with the development. Together these provisions mean a property owner who lets a street tree's canopy droop below seven feet over a sidewalk, or below 12 feet over a bike lane or parking area, is out of compliance with the maintenance duty the code assigns to them, separate from the developer's original planting obligation.
