Transportation Impact Fee Program

About the Program


The City of Des Moines has had a Transportation Impact Fee (TIF) Program since 2003. Transportation impact fees are collected to fund improvements that add capacity to the transportation system accommodating the travel demand added by new development.

Pacific Ridge


New developments in the Pacific Ridge zone are also subject to the Pacific Ridge Transportation Mitigation fee. As established in Exhibit B of Ordinance 1298, commercial developments that front along the Pacific Highway South corridor are required to pay the citywide transportation impact fee, but receive a credit toward the transportation impact fee equal to the amount of the Pacific Ridge Transportation Mitigation fee. New residential developments located east of the Pacific Highway South corridor are currently not required to pay the citywide TIF.

Annual Adjustment


The citywide TIF and the Pacific Ridge Mitigation Fee are adjusted annually. The adjustment is based on the Construction Cost Index as published in the Engineering News Record (ENR) – typically in March.
