Chenoweth Interchange Area Management Plan (IAMP)

City of The Dalles and Wasco County, Oregon

APG worked in collaboration with Kittelson & Associates to prepare an Interchange Area Management Plan (IAMP) for the Chenoweth /I-84 interchange located in the Columbia River Gorge. Project tasks included conducting a regulatory review, stakeholder interviews, assessing existing land use conditions in the early phases of the project, and preparing implementation measures and new development regulations in the later phases of the project. 

The new development regulations consisted of an IAMP zoning overlay district that regulates access management, trip allocations, and traffic impact reviews in the district. The zone also requires review and update of the IAMP in certain circumstances.  These development code amendments worked in conjunction with other implementation measures APG helped to develop, including a Supplemental Transportation Systems Development Charge (STSDC) and an Intergovernmental Agreement (IGA) between the City of The Dalles, WascoCounty, and ODOT that stipulates each agency’s funding responsibilities for specified improvements and for IAMP monitoring and updating. The adopted IAMP replaces an earlier restriction on development of commercially re-zoned land near the interchange and enables build-out of remaining industrial land.
