Public involvement

Your thoughts and opinions are important to us. Public involvement efforts related to this project have been part of WSDOT's I-205 corridor planning process and the City of Vancouver's transportation planning process for several years.

A NE 112th Avenue Traffic Safety Corridor Steering Committee convened on January 28, 2009 to discuss safety concerns on NE 112th Avenue and develop partnerships with community groups to reduce fatal and disabling collisions on this roadway.

On June 5, 2008, WSDOT hosted a pre-construction open house to discuss the project with the public and explain what kind of traffic impacts motorists can expect during construction.

On February 16, 2006, WSDOT and the City of Vancouver hosted a public open house about this project to introduce the project to the public, provide information and get the public's feedback on issues to be addressed.

On January 12, 2005, WSDOT and the City of Vancouver hosted a public open house about the project. This open house introduced the project to the public and presented the preliminary design. The public also had an opportunity to ask questions and provide feedback to WSDOT and the city about the project. A newsletter (.pdf, 533kb) about the project and the open house was mailed out to residents and businesses in the area in mid-December 2004.

A summary (.pdf, 46kb) of this open house and the comments received both verbally and in writing from the public is available for review.

An Access Hearing occurred on November 30, 2005. The hearing was a formal, legal forum for property owners affected by this project to give testimony about any concerns, suggestions or issues they have.

WSDOT will post the latest public involvement information on this Web page and the SW Region's Public Involvement page when public meetings or open houses are scheduled. Mailings will also help inform area residents and businesses of project progress and opportunities to provide input.


Increasing safety is our priority

These improvements will help alleviate the occurrence of rear-end-type accidents on the Mill Plain Boulevard off ramp, which has been identified as a high accident location. These locations are those places on the highway system that experience a higher than average number of accidents compared to other locations with similar characteristics.


Environmental protection

WSDOT began the necessary environmental studies for this project in Summer 2003. The studies will detail the project's environmental impacts (natural, ecological, societal and economic) in order to guide future design and construction.

When funding became available for the I-205, Mill Plain Interchange to NE 18th Street project, environmental policy required that we evaluate the environmental issues for the combined projects, the I-205, NE 112th Connector and Stage 1 of the I-205, Mill Plain to NE 18th Street Interchange projects.

Additional environmental documentation is needed in the area where the NE 112th Connector meets the new NE 18th Street interchange ramp system. WSDOT is committed to preserving the environment and makes every effort to assess and minimize environmental impacts from its projects.

There are typically two components to WSDOT's erosion control and water quality protection efforts on highway projects: temporary measures during construction activities and permanent measures for when the project is completed. WSDOT incorporates "Best Management Practices" to reduce environmental impacts on water quality and provide erosion control at the construction site. These practices include covering disturbed soil to prevent erosion, and using silt fences, straw bales, and inlet filters to prevent sediment from leaving the work site.

Permanent erosion control and water quality measures will be addressed with construction of drainage structures, swales, and infiltration ponds that collect and filter highway storm-water runoff. This interchange project may provide opportunities to improve wetland habitat and storm water runoff in the area.

Will this project impact tribal resources?

At WSDOT we seek to address the concerns of the tribal nations using the process outlined in Section 106 of The National Historic Preservation Act and the WSDOT Tribal Consultation Policy adopted in 2003 by the Transportation Commission as part of the WSDOT Centennial Accord Plan.

This process is not applicable because the project does not impact tribal lands.
