|The Chenoweth Interchange on Interstate 84 was built in 1997. It was designed to be a service level interchange that would safely and efficiently accommodate traffic associated with The Port of The Dalles and other industrial properties in the area, and visitors to the Columbia Gorge Discovery Center. |
In 2006, the City of The Dalles (City) adopted a zoning change from industrial land to commercial/light industrial land for 67 acres near the Chenoweth Interchange. Soon thereafter, WM3, a local land developer, submitted a site plan for 25 acres of the newly rezoned land.
Additionally, through an intergovernmental agreement between the City, the Oregon Department of Transportation (ODOT), and WM3, property covenants were placed on the remaining 42 acres which prohibit “non-industrial” development until an Interchange Area Management Plan (IAMP) is adopted by the City.
|What is an IAMP?|
|An Interchange Area Management Plan is a planning document used to help protect the function of an interchange over time, and consequently the state’s investment in the facility. In general, an IAMP: |
- Is a joint plan between ODOT and local government.
- Manages the relationship between transportation and land use.
- Is the primary tool to protect the function of state highway interchanges.
- Is the commitment by ODOT to provide the state transportation facilities
- Is the commitment by the local government to 1) provide the supporting local street network and 2) ensure future land uses protect the interchange function.
- Serves as the long-term (20+-year) plan for interchange area.
Building new interchanges or modifying existing interchanges is very costly. Therefore, it is in the interest of the state, local governments and citizens to ensure that an interchange functions as it was designed, for as many years as possible. Without proper land use planning and management of the access to the interchange and the local street system, the amount of traffic the interchange was design to handle could be exceed causing congestion and safety concerns in the area surrounding the interchange.
The Oregon Administrative Rules (OAR) 734-051-0155 established a requirement for IAMP’s for new or substantially modified interchanges. In addition, Oregon Highway Plan (OHP) policies direct the Oregon Department of Transportation (ODOT) to plan and manage interchange areas for safe and efficient operation. Development of an IAMP is part of a planning process intended to evaluate existing conditions, assess limitations, identify long-range needs, and recommend potential management actions to protect the function of the interchange.
