A summary of Metro Council decisions, alternatives studied and opportunities for public comment related to development of the locally preferred alternative for the South Corridor Project.
The South Corridor project began as part of the South/North Corridor study. After voters did not reaffirm funding for the South/North light rail project in November 1998, elected officials conducted a series of “listening posts” throughout the region to find out how community members thought transportation needs in the South/North Corridor should be addressed. The feedback led policy makers to advance a light rail project in the northern portion of the corridor and to begin a study of non-light rail options in the southern portion of the corridor.
In 1999, the South Corridor study began to evaluate a wide range of transportation options including river transit, high occupancy vehicle lanes, high occupancy toll lanes, busway, bus rapid transit and commuter rail. After extensive public input and technical evaluation, busway and bus rapid transit options were selected to move forward for more detailed analysis. Southeast Portland and Milwaukie neighborhood leaders continued to ask that light rail be included in the study. In the spring 2001, the policy committee responded to community requests and added light rail between Milwaukie and Portland and between Gateway and Clackamas to the study.
The South Corridor Supplemental Draft Environmental Impact Statement (SDEIS) compared five transit alternatives with a no-build alternative. The transit alternatives included bus rapid transit, busway and light rail routes. In April 2003, after a 61-day public comment period, the Metro Council recommended the two-phase locally preferred alternative with a preliminary recommendation to construct light rail on the Portland Mall during the first phase.
During the summer 2003, staff prepared an amendment to the SDEIS for the downtown portion of the project. The Downtown Portland Amendment to the SDEIS compared light rail on the Portland Mall to a no-build alternative. After a 45-day public comment period, the Metro Council confirmed the South Corridor Locally Preferred Alternative with the first project phase including new light rail from Gateway to the Clackamas Town Center and in downtown Portland.

The two-phase plan calls first for construction of light rail from the Gateway district to the Clackamas Town Center, as well as extensions along Southwest Fifth and Sixth avenues in downtown Portland. The second phase would connect Milwaukie and Southeast Portland to the system in downtown Portland.

The purpose of the refinement report was to review, at a conceptual level, proposed design options against a wide range of criteria that represent considerations in the SDEIS.
The criteria include considerations like cost, travel time, ridership, land use connections and compatibility, engineering feasibility, potential for traffic and/or property impacts and connection to other transit, bike and walking facilities.
The refinement of design options focuses on two areas: southern terminus and Willamette River. Specifically, these are the issues that were studied in the refinement report:
The findings discussed in the refinement report were based on the limited design and information that was then available on the design options. Ridership estimates presented, for example, were not based on full transit model forecasting runs. More detailed information will be developed on all options carried into the SDEIS during that study process.

In addition to the refinement report, alignment maps, some of which are also in the refinement report, are available for viewing and download.
The downtown Milwaukie alignments review reports on potential light rail alignments for downtown Milwaukie along Southeast McLoughlin Boulevard and/or Southeast Main Street. The report is in response to Milwaukie Mayor Jim Bernard’s request to the Portland-Milwaukie Light Rail Project steering committee for an opportunity to fully examine a light rail alignment in downtown Milwaukie on these thoroughfares.
