What is the purpose of an IAMP? An IAMP is a long-range (20+ year) plan and agreement developed to protect interchange function and operations, manage land use and transportation decisions in the IAMP area, and balance local and regional access and travel needs.
Why an IAMP? An IAMP offers the opportunity to think proactively about the future of an interchange. For the I-5 interchange at Chemawa Road, the IAMP process will bring staff, citizens and elected officials from Keizer, Salem and Marion County together to discuss future plans for the area and cooperatively agree on the best ways to manage the movement of traffic, goods and people through the interchange.
How will a plan for the interchange areas be developed? IAMP’s should, as much as possible, utilize available traffic, land use and environmental information specific to the area. One of the first steps in the process will be collecting that information to determine the current and future transportation needs in the area. The IAMP will need to consider ODOT standards, how to provide access to private parcels near interchanges/intersections, how traffic circulates, and how properties near interchanges develop in future.
What problems will be addressed by the IAMP? Potential problems to address could include: congestion, approach locations, crash histories, expected levels of development, plan designations and/or zoning in excess of the transportation network's capacity, lack of a local street network, heavy truck traffic, seasonal tourism or other economic factors, and proximity to rural resource lands.
How will the public be involved? The development of the IAMP insists on close coordination between ODOT and the affected local government(s), in this case, the Cities of Keizer and Salem and Marion County. Development of the plan should also include public outreach to affected property and business owners, and users of the transportation facility. Public meetings will be held throughout the IAMP preparation in order to keep the public informed in the process.
Two committees have also been formed, one a technical committee made up of staff from the many government agencies involved in the areas and the other a group representing major stakeholders in the Chemawa Interchange area. The second group, the Stakeholder Advisory Committee (SAC), will meet regularly throughout the process to inform the plan’s authors of the needs of residents, property owners and businesses in the area. SAC meetings are open to the public.
What happens after the plan is written? With help from the consultant team, the Project Management Team will produce the final IAMP document and accompanying ordinances for adoption by the Keizer City Council, the Salem City Council, the Marion County Board of Commissioners and the Oregon Transportation Commission (OTC).
How Long Will The Planning Process Take? The IAMP planning process is beginning now and the management plan will be developed over the next year with an anticipated adoption date in late 2009.
