About Washington Park Arboretum
The Olmsted Brothers were called upon twice to consult on this unique park, which is jointly managed by the City of Seattle, the Arboretum Foundation and the University of Washington – first from 1903-1907 for the boulevard design and then from 1934-1939. Nestled in a long, narrow valley, Washington Park’s most iconic Olmsted features include the first section of scenic Lake Washington Boulevard (02718), which extends south from the park, connecting several parks along the lake shore to reach Seward Park, as well as the 230-acre arboretum, designed by James Frederick Dawson from 1934–1939. Its crowning feature, Azalea Way, is a gently winding meadow lined with its namesake flower.
