The E. J. O'Donnell House in Multnomah County, Oregon, just outside the Portland municipal boundary, was designed in 1938 by architect Richard Sundeleaf for dairyman and cattle breeder Edward J. O'Donnell. It was completed in 1940.The single-story house was designed to be wheelchair-accessible for a child of the O'Donnells'. It has a "multiplicity of steeply-pitched cross gables at the east end and a variegated exterior of brick, lapped weatherboards as gable cladding, and secondary siding of boards and molded battens." It has bays and projections on its faces, and on the northeast has a kitchen/utility wing and on the southwest has a garage/bedroom wing. Its NRHP nomination describes that:The house displays the essential qualities for which Sundeleaf's Arts and Crafts architecture is admired. Porches have heavy post and beam framing. Solid craftsmanship emphasizes interior wood paneling and trim. A square module is used for division of window space, including sidelights for view windows on which such premium is placed in Portland's west hills. Building volumes are stepped down to the landscape through sheltered terraces and projecting window bays. The architect brings forward from earlier projects (see Clarence Francis House) a rear gallery—an updated screens passage which in archetypical manor houses leads to private compartments from the great hall or circulation core. It was listed on the National Register of Historic Places in 1994.

Landscape architecture firm Walker Macy of Portland designed the memorial, while construction labor and materials were almost entirely volunteer donations.The font used in the memorial was created for the exclusive use of the Memorial. It was designed by Janis Price, and is called Hoyt, in recognition of the Arboretum. The memorial is located in the Hoyt Arboretum, adjacent to the World Forestry Center and the Oregon Zoo. The nearby trail system connects to Forest Park and is close to the International Rose Test Garden and the Portland Japanese Garden.

Washington Park is a light rail station in Portland, Oregon, United States, served by TriMet as part of the MAX Light Rail system. Situated between Sunset Transit Center and Goose Hollow/Southwest Jefferson Street station, it is the 17th and 3rd station eastbound on the Blue Line and the Red Line, respectively. The station's two tracks and island platform are part of the Robertson Tunnel beneath Portland's West Hills. Its head house and surface-level plaza occupy the middle of a parking lot surrounded by the Hoyt Arboretum, Oregon Vietnam Veterans Memorial, Oregon Zoo, Portland Children's Museum, and World Forestry Center. Washington Park is the only completely underground station in the MAX system. At 260 feet (79 m) below ground, it is the deepest transit station in North America and in the western hemisphere, and the sixth-deepest in the world.The station opened in September 1998 as part of the Westside MAX extension to downtown Hillsboro. Connections include TriMet bus route 63–Washington Park/Arlington Heights and a free seasonal shuttle. Various hiking trails, some a part of Portland's 40-Mile Loop, connect the station to other parts of Washington Park, including the International Rose Test Garden and the Portland Japanese Garden.

The Washington Park & Zoo Railway (WP&ZRy) is a 2 ft 6 in (762 mm) narrow gauge recreational railroad in Portland, Oregon's Washington Park with rolling stock built to 5/8 scale. Opened in three stages in 1958, 1959 and 1960, it provided transportation between the Oregon Zoo, Hoyt Arboretum, International Rose Test Garden, and the World Forestry Center. The extended line was about 2 miles (3.2 km) long. The service is currently operating on a 1-mile (1.6 km) loop within the zoo grounds. The railway carries about 350,000 passengers per year.The railroad is operational year-round except in January and part of February, when it is closed for required maintenance. Special events occur during the winter holidays. As of 2018, the price of a ticket was $4.00 for the short 6 minute internal loop., but zoo admission was also required. Zoo officials announced in September 2013 that the line would be closed for about one year for construction, with the last day of service scheduled to be September 22. The temporary closure was necessitated by the construction of the zoo's new Elephant Lands exhibit, which will also include remodeling of other parts of the zoo grounds. The short-loop route through the southwest part of the zoo grounds was scheduled to be removed permanently, and during the one-year suspension of service a new section of track was to be laid to create a replacement for the short loop. Train operations returned running on the new Zoo Loop line only as of November 22, 2014. In May 2018 an online petition was created in opposition to the Washington Park Master Plan's endorsement to remove the "long route", which runs from the Oregon Zoo to the International Rose Test Garden. The master plan primarily called for the removal of all tracks so that it could be replaced by a paved twelve foot (12') wide path. As of May 2020, over 37,000 people have signed the online petition in support of keeping and repairing the, "long route".
