Seward Park was designed by the Olmsted Brothers. It is located in the Seward Park neighborhood at 5895 Lake Washington Blvd. S, 98118 It is 300 acres.
Originally called Bailey Peninsula, hilly Seward Park boasts some of Seattle’s oldest-growth native forest thanks to John Charles Olmsted, who helped save it from development by encouraging the city to purchase to be included in the park and boulevard system he designed in 1903. In the 1903 report, Olmsted encouraged the city to acquire it before the forest was injured by logging or clearing for development.
Olmsted's 1912 preliminary plan for the park locates programmed spaces, such as a dancing pavilion, basketball and tennis courts, and a small boat harbor, on the northern shore of the park. The majority of the park featured the old growth forest, which visitors could explore via several meandering trails. The plan is a prime example of a Olmsted Brothers’ naturalistic plan for a large park, in contrast to the more formally designed Volunteer Park.
Olmsted's plan was never fully implemented but his 1912 plan influenced later development in the park and the forest has largely been preserved.
