Portland-Milwaukie Light Rail Transit East Segment

Portland and Milwaukie, OR

The Portland to Milwaukie Light Rail (PMLR) project connects Portland State University and downtown Portland with the South Waterfront community, the city of Milwaukie, and Clackamas County. Starting in February of 2011, DEA provided final design services and continues to provide design services during construction (DSDC) for the East Segment of the alignment, which started revenue service in September 2015. The East Segment, one of three projects within the overall alignment, starts at the Oregon Museum of Science and Industry (OMSI) on the east bank of the Willamette River and continues south to the city of Milwaukie, with a terminus at Park Avenue in the community of Oak Grove. The overall route includes eight stations, two of which are park-and-ride facilities.

DEA’s final engineering design services included: track alignment design; civil engineering; stormwater management and treatment; utilities and street improvements; structural engineering of bridges and retaining walls; architectural design including station design, integration of station urban design developed by TriMet staff, and urban/suburban context; and landscape design. The final design team also had to integrate with a general contractor as part of a CMGC delivery package. Also included was integration of the systems engineering design, which was performed under separate contract by LTK Engineering. The project is funded by local match and federal grant dollars, and therefore all project work programs, procedures, and products were subject to Federal Transit Administration (FTA) review and approval.
