Road Impact Fee Program

Overview

The MTCP Update project will also update the established methodology for road impact fees for the County. The Road Impact Fee Program is designed to ensure that new development helps fund roadway infrastructure improvements needed to accommodate growth from residential and commercial development. 

As new developments are proposed, their land uses are converted to trips based on the land use categories and adjusted trip rates. The improvements needed to support new development, minus existing deficiencies, will be divided by the number of new trips to determine a new fee amount. The tables and maps of eligible improvements will be updated and signals on major roads will be included as well. 

The unit costs to determine the fees and credits shall be updated and recommended by the Transportation Impact Fee Advisory Committee. Trip rates will be derived from the most current version of the ITE Trip Generation Manual (11th edition, 2021). The updated road impact fees will be determined by multiplying the estimated trip generation by the cost per trip.
