The purpose of this study was to provide an independent review of the Washington County Traffic Impact Fee (TIF) and to make recommendations for changes in the fee structure which would improve its equity and promote efficiency without unduly increasing its complexity. TIFs are becoming more common as growing communities seek equitable and efficient methods to fund their new infrastructure requirements. Despite their relatively simple conceptual characterization, there are many difficult issues which must be addressed in specifying the general form of the impact fee and in implementing the fee. The TIF for Washington County is analyzed with respect to a variety of these issues. This report presents the major findings of that analysis. The key issues addressed are the adequacy of the revenue from the system, the equity of the allocation of charges among different land uses, and the possibility of refining the system without making it unduly complex. In particular, there is a different charge per trip for each of five major land use categories and there is a cap on the number of trips used in the formula. These features are intended to make the TIF more accurately reflect the demand for road capacity generated by different types of development, but there is question as to whether this system achieves an equitable allocation of TIF charges.
