Before you cut the curb to widen your drive approach, please be aware that a permit is required.
To obtain a Curb Cut Permit, it requires a few things to be done:
Draw up a site plan. A site plan is a bird’s eye view of your property, in this case, more of the front yard. It doesn’t have to be professionally done, just as long as it has the following dimensions:

The width of the property

The width of the existing approach, including the downward cut
The location and width of the proposed cut.NOTE: The total width of an approach cannot exceed 30% of the total width of the property; it also cannot be any closer than 4’6” from where the side property line would meet the curb

Bring/send the Site Plan to the City Planner for approval. (City Planner can be found at City Hall 5051 S. 1900 W., or via email at sparkinson@royutah.org, or, if you have any questions, call him at 801-774-1027)

Once approved or denied, you will receive a copy of the site plan. (A denial will have an explanation and/or things that can be done to get it approved)
When you receive an Approved Site Plan, bring/send the Site Plan to Public Works at 2626 W. 5525 S., or via email at publicworks@royutah.org, or if you have any questions, call (801) 774-1090 to obtain the permit.

This permit costs nothing. However, because the curb is owned by the city, all work must be done by a licensed contractor.

The permit will require their contractor’s state license number.
The work needs to meet city standards and will be inspected by the city.
