Impact Fees

Impact Fees are one time fees assessed on new construction, remodels/additions, and commercial builds. Impact fees must be paid before a water concurrency letter can be issued by Mountain Regional Water District, which is necessary to apply for a building permit by Summit County. These impact fees are used to pay the capital impact of a user or a group of users on the water system. All of our impact fees follow the State of Utah Impact Fees Act. Impact Fees are based on the demand any new construction places upon the water system.
