Marine Drive Interchange Area Management Plan
|**The Marine Drive IAMP process has been on hold pending bridge design decisions. Now that a bridge design type has been chosen, it's expected that work on the IAMP will begin again.** |
The Oregon Department of Transportation is working on the Marine Drive Interchange Area Management Plan (IAMP) in conjunction with the City of Portland and the Columbia River Crossing (CRC) project. The CRC project will build a new I-5 bridge between Oregon and Washington, extend light rail to Vancouver, and improve seven interchanges. The Marine Drive IAMP will address the transportation, safety, and land use issues associated with changes to the Marine Drive Interchange. A second IAMP has also been developed for the Hayden Island Interchange.
The purpose of an IAMP is to ensure safe and efficient operations between connecting roadways, protect the function of the interchange, and minimize the need for future major interchange improvements. It is required for any new or significantly reconstructed interchange (OAR 734-051-0155.6). Because new interchanges are very costly, state and local governments, as well as citizens, have an interest in ensuring interchanges function as intended for as long as possible, while still supporting planned land use.
Marine Drive Interchange Function Statement
The primary functions of the Marine Drive Interchange are to serve industrial access and goods movement by connecting the Marine Drive industrial and employment corridor to I-5, and to provide a connection from Hayden Island to the mainland. Secondary functions are to provide regional access for existing residential areas near the interchange, serve special events at the Portland Metropolitan Exhibition Center (Expo), and serve nearby recreational uses including East Delta Park.
The Marine Drive Interchange is not intended to serve or encourage highway-oriented commercial or large format retail development beyond that already existing or allowed outright in the vicinity of the interchange.
The goals of the Marine Drive IAMP are to:
- Ensure safe and efficient operations between connecting roadways and to protect the function, operations, and safety of the interchange.
- Support the goals and objectives of the Columbia River Crossing project.
- Establish that ODOT and the City of Portland will continue to coordinate development activities in the vicinity of the interchange.
- Support the goals and objectives established by the policies and standards of both ODOT and the City of Portland.
- Support land uses that are existing or allowed outright in the vicinity of the interchange.
The objectives of the Marine Drive IAMP are to:
- Define the function of the interchange.
- Develop a multi-modal transportation system and access management plan that assures safe and efficient operations in the interchange area. To the extent possible, meet Oregon Highway Plan mobility and access management spacing standards. To the extent possible, meet City of Portland transportation standards.
- Ensure there is adequate capacity to meet projected demand in the interchange management area during the planning horizon.
- Develop a plan that is coordinated with the Columbia River Crossing project and City of Portland adopted plans.
- Support development of a local street network that can accommodate local trips without requiring travel through the interchange.
What will – and won’t – the Marine Drive IAMP do?
- This IAMP will set the framework for future driveway decisions in the interchange area.
- This IAMP will not address individual driveway locations.
- This IAMP will summarize and support City of Portland plans for the area.
- This IAMP will not propose changes to existing land uses.
- This IAMP will recognize the unique character of the area.
- Meetings with affected property owners and communities (March and April)
- Publication of the draft Marine Drive IAMP for public comment (late March)
- Marine Drive IAMP Open House (early April)
- Presentation of the Marine Drive IAMP to the Oregon Transportation Commission for adoption (mid-May)
- Development of the Access Management Strategy in consultation with property owners and the City of Portland (Fall 2010 – Winter 2011)
