Find out about the comprehensive planning effort to create livable and sustainable communities along the corridor between Portland, Tigard and Sherwood through integrated community investments in land use and transportation.
To move the plan into results, the Southwest Corridor Plan has entered into a refinement phase, focusing on the transit aspects of the shared investment strategy while exploring funding strategies and further planning for the recommended roadway, bicycle, pedestrian, parks, trails and natural area projects.

During the refinement phase, project partners will further narrow the high capacity transit design options that came out of the initial phase of the Southwest Corridor Plan and move forward the most promising for further study in a Draft Environmental Impact Statement. To better understand the options for high capacity transit in the corridor, the Southwest Corridor Plan Steering Committee has directed staff to study in more detail:
A major task in this phase will be to get enough information about all of these possible design options to narrow down to a few of the most promising to take into more detailed analysis. This will include looking at preliminary cost estimates, traffic analysis, automobile lane treatment needs and other performance measures as well as feedback from the public on which ideas seem unworkable.
During this time, TriMet will take a fresh look at improving transit service with the creation of the Southwest Service Enhancement Plan, seeking to address the demand for more local and regional transit service connecting communities in the Southwest Corridor to jobs and educational opportunities throughout the region.
In July 2013, the Southwest Corridor Plan Steering Committee recommended transit alternatives for further study along with a set of potential roadway, bicycle, pedestrian, parks, trails and natural area investments that support land use, transportation and community-building goals in the corridor as part of the Southwest Corridor Shared Investment Strategy. The policies and projects are aimed at supporting development that is consistent with the local communities’ aspirations for key places in the corridor.

The Southwest Corridor Plan integrates multiple efforts: local land use plans to identify actions and investments that support livable communities; a corridor refinement plan to examine the function, mode and general location of transportation improvements; and the transit alternatives analysis to define the best mode and alignment of high capacity transit to serve the corridor. The plan is a partnership between Metro, Washington County, the Oregon Department of Transportation, TriMet and the cities of Portland, Sherwood, Tigard, Tualatin, Beaverton, Durham and King City.
The integrated approach allows Metro and its partners to measure the success of the transportation project against some key elements of a successful region, things like vibrant communities, economic prosperity, clean air and water and equity. Transportation and land use decisions that support local land use goals for jobs and housing will be fundamental to a successful outcome.
