APPENDIX A – DETAILED MAPS AND DESCRIPTIONS OF LIGHT RAIL ALTERNATIVES
This appendix provides detailed information to supplement Chapter 2 – Alternatives Section Page Considered of the Southwest Corridor Light Rail Transit Network Assumptions ...... A-1 Alignment Alternatives ...... A-4 Project Draft Environmental Impact Statement Stations and Park and Rides ...... A-18 (EIS). Marquam Hill Connection Options ...... A-26 Operations and Maintenance (O&M) Facility Options ...... A-31 Transit Network Assumptions Station Access Improvement Options ...... A-34 Construction Activities ...... A-42 With the opening of a new light rail line, the Tri-County Metropolitan Transportation District of Oregon (TriMet) typically makes adjustments to the surrounding bus network to optimize ridership and service efficiency. Adjustments to local bus service assumed for the purpose of the analysis in this Draft EIS are described below. TriMet would make final decisions on bus service and routing changes for the Southwest Corridor Light Rail Project shortly before the opening of service.
Two lines operating on SW Barbur Boulevard in the No-Build, the line 12 from Tigard to downtown Portland and the line 94 express from Sherwood to downtown Portland, would be removed. The line 93 from Sherwood to Tigard would be extended to the Barbur Transit Center with service added to maintain frequency lost with the line 94 removal. The line 44 from downtown Portland would be shortened to terminate at PCC-Sylvania, removing its No-Build routing between the campus and Bridgeport Village along SW Kerr Parkway and SW Boones Ferry Road. Instead, the line 96, an express route between Wilsonville and downtown Portland in the No-Build, would be re-routed north of Bridgeport to travel along the roads from which the 44 would be removed. The line 96 would serve PCC-Sylvania and continue along SW Capitol Highway to terminate at the Barbur Transit Center.
With light rail serving the Marquam Hill connection, lines 64 and 65 to Marquam Hill, from Tigard and Burlingame, respectively, would be removed. Line 8, serving between NE Portland and Marquam Hill, would have peak service reduce by three vehicles per hour because its loads would be reduced by light rail service. Lines 1 and 38 would be shortened to terminate at Burlingame near the Custer station instead of continuing into downtown Portland. The line 54 from Beaverton would utilize a shared transitway with the light rail between SW Capitol Highway and SW Lincoln Street, allowing it to avoid congestion and improve reliability.
Figures A-1 and A-2 show the assumed transit network for the No-Build Alternative and light rail alternatives, respectively.

The maps illustrate the location of the alignment, stations and park and rides. Park and rides are labeled with their assumed maximum capacity. Along the alignment, the maps show whether the alignment would run in a roadway or separated from roads, and whether it would be at grade, structured, or in an underpass. At-grade intersections along the alignment are identified as signalized, gated or both. Additional protected walk/bike crossings away from stations or intersections are also labeled.

A path would connect SW Barbur Boulevard to a 100-foot-tall elevator tower west of SW Barbur Boulevard. A 140-foot-long bridge would connect the elevator tower to a path along the hillside east of SW Terwilliger Boulevard. The option would include an at-grade crossing of SW Terwilliger Boulevard with a pedestrian crossing signal. On the west side of SW Terwilliger Boulevard, stairs and ramps would lead to the second elevator tower, which would be approximately 120 feet tall. A 190-foot-long bridge would connect the upper elevator to SW Campus Drive at the third floor base of Kohler Pavilion. Because the upper elevator tower and bridge would be directly under the path of the Portland Aerial Tram, Connection 1A could not tie in directly to the seventh floor of Kohler Pavilion as the other connection options would. Instead, pedestrians would cross SW Campus Drive and walk to an entrance to Kohler Pavilion to reach a bank of elevators, or continue along SW Campus Drive to other facilities. • Connection 1B: Elevator/Bridge and Recessed Path would be identical to Connection 1A for the lower elevator and bridge near SW Barbur Boulevard, but would differ at SW Terwilliger Boulevard and at the upper elevator and bridge west of SW Terwilliger Boulevard. Connection 1B would feature a below-grade crossing of SW Terwilliger Boulevard, which would include ramps and stairs on the east side of the roadway to connect to the path that runs along the east side of SW Terwilliger Boulevard. West of SW Terwilliger Boulevard, a series of stairs and ramps would connect the pedestrian underpass to a wide recessed path at the base of the upper elevator, which would be 170 feet tall, including the portion embedded below grade connecting to the path. A 150-foot-long bridge would connect the elevator to the seventh floor of Kohler Pavilion. • Connection 1C: Elevator/Bridge and Tunnel would be identical to Connection 1B from SW Barbur Boulevard to the below-grade crossing of SW Terwilliger Boulevard, but it would differ west of SW Terwilliger Boulevard. The pedestrian underpass below SW Terwilliger Boulevard would emerge into an open recessed area west of the roadway, about 30 feet below the level of the surrounding ground. A series of ramps and stairs would connect this open area to the sidewalks on SW Campus Drive and the west side of SW Terwilliger Boulevard. A 180-foot-long tunnel would lead from the open area to the upper elevator tower. The upper elevator would be 200 feet tall, including the portion embedded underground. A 120-foot-long bridge would connect to the seventh floor of Kohler Pavilion. • Connection 2: Full Tunnel is distinct from the other three Marquam Hill connection options and has a single tunnel, an elevator and a bridge. A path from SW Barbur Boulevard would lead to an open plaza area partially embedded into the hillside. A 450-foot-long tunnel would extend into the hillside under SW Terwilliger Boulevard and connect to an elevator, which would be 290 feet tall, including the portion embedded underground. A 130-foot-long bridge would connect the elevator to the seventh floor of Kohler Pavilion.

There are two locations being considered for a light rail O&M facility in Tigard, one of which includes variations to pair with each route configuration. See Figures A-28 and A-29 for a map of each O&M facility option. The first location, the Hunziker Facility, would encompass about 20 acres near downtown Tigard adjacent to the freight rail tracks and SW Hunziker Street, and could serve any of the Segment C alignment alternatives. The facility layout would be designed to provide 9,000 feet of storage track for approximately 42 light rail vehicles (storage for 10 additional vehicles than is needed for the project to allow for system growth and operations flexibility) and accommodate most maintenance functions necessary to operate the light rail system, including 10 maintenance bays, a space for wheel truing, vehicle wash area, a unit repair facility (for vehicle parts) and parts storage (both indoor and outdoor). The Hunziker Facility could accommodate additional storage tracks for up to 60 vehicles total to support additional system growth in the future. The Hunziker Facility would also include a surface parking lot for employees and fleet vehicles, administrative space to support the on-site operations, and on-site stormwater management. Up to 85 percent of the site would be improved with impervious surfaces, consistent with local zoning regulations for industrial development. Light rail vehicles would access this facility via switches on the main light rail alignment parallel to the WES and freight railroad tracks. The second location, referred to as the 72nd Facility, would encompass about 17 acres southeast of the Tigard Triangle between SW 72nd Avenue and I-5. This location would provide the same facilities as the Hunziker Facility, but with slightly reduced storage and maintenance capacity. There are two options for the specific location and layout of this facility, depending on the light rail alignment: • The Through 72nd Facility would be across from SW Landmark Lane and could serve the through-routed alternatives that would operate adjacent to I-5 south of Tigard (Alternatives C1 and C3). Light rail vehicles would access this facility via switches on the adjacent exclusive trackway to the south of the site (between SW 72nd Avenue and I-5). • The Branched 72nd Facility would shift the facility slightly to the north to serve the branched alternatives (Alternatives C5 and C6). Light rail vehicles would access this facility via switches on the trackway adjacent to I-5. Both 72nd Facility options would provide 7,500 feet of storage track for approximately 36 light rail vehicles, vehicle wash, parts storage (both indoor and outdoor), surface parking for employees and fleet vehicles, administrative space to support on-site operations and on-site stormwater management. Both options would improve up to 85 percent of the site with impervious surfaces, consistent with local zoning regulations for industrial development.

Construction Sequence and Activities Linear projects such as the Southwest Corridor Light Rail Project are typically divided into various segments or line sections for construction. The construction sequence would vary depending upon existing conditions, the characteristics of the light rail facilities, temporary traffic control requirements and the sensitivity of the locations within the segments (in-street versus off-street construction, for example). Project development would further define the design and requirements for the facilities to be constructed. This refinement informs the selection of contracting methods and the development of work-specific construction planning. Work-specific construction plans would be developed during the final design effort to establish the limits for the various construction phases and construction contracts, the estimated schedule and duration of each, the appropriate sequencing and the minimum necessary level of restrictions to be placed on construction work to address the mitigation of impacts. Final refinement of construction plans would continue into the construction procurement selection and negotiations, and early contractor-provided plans would finalize the requirements to ensure that there would be appropriate mitigation of construction impacts. Where possible, construction activities would A-42 Southwest Corridor Light Rail Project Draft EIS June 2018 Appendix A – Detailed Maps and Descriptions of Light Rail Alternatives be coordinated with other capital improvement projects, including projects carried out by the local jurisdictions, to help minimize construction impacts. In addition, TriMet will actively engage with local jurisdictions as the project nears construction to develop a Conduct of Construction plan that would guide coordination throughout construction. Construction Timing and Duration Following a Record of Decision, final design and funding agreements, construction is projected to begin as early as 2021. The duration of construction for the overall project would span approximately three years. The specific activities and actual duration would depend on the design of each segment. Typically, construction in any segment includes multiple phases, including demolition, utility relocation, major structures, civil and track construction, systems installation and station amenities. Although construction activity would occur over the length of the project during this time, the impact would not be continuous along the corridor for the full duration. An integrated project schedule would be used to manage the implementation of multiple construction contracts. Construction Staging Areas Contractor mobilization is part of the initial construction work and typically requires the development of staging areas. Staging areas are needed before any construction work begins, but the need and the proximity of the staging areas to the construction site vary depending on the features being constructed, availability of space, presence of sensitive areas, schedule restrictions and the contractor’s desires. Bridges and aerial structures are most practically staged adjacent to or very near the construction site. Other types of staging and materials storage are more flexible in location. Specific staging area locations will be identified when the project is in final design. To minimize impacts to properties, parcels that would be needed for the project footprint could be used for staging areas before the construction of project elements on those parcels. Project staging areas are typically used to accomplish or accommodate one or more of the following: • stockpiling, loading and hauling of excavations and demolished materials • receipt and stockpiling of materials and equipment • assembly and, in limited cases, fabrication of project elements • laydown of major prefabricated elements before their erection or assembly • construction field administration offices • construction worker parking June 2018 Southwest Corridor Light Rail Project Draft EIS A-43 Appendix A – Detailed Maps and Descriptions of Light Rail Alternatives
