    Transportation Impact Analysis

    Header Image
    Crosswalk-with-RRFB.jpg

    A transportation impact analysis, or TIA, is a study of the potential transportation impacts of a development on the surrounding transportation system. The purpose of the study is to document the impacts and recommend on-site and off-site mitigation for those impacts. 

    A TIA is required for any new development, redevelopment or change of use (including tenant improvements). 

    The application will hire a consultant to provide the TIA. The consultant must be a professional engineer, licensed in Washington state. There are two types of traffic reports. For more information, refer to the TIA Guidelines.
