Alki Beach Park was influenced by the Olmsted Brothers. It is located in the Alki Beach neighborhood at 1702 Alki Ave SW, 98116. It is 135.9 acres.
John Charles Olmsted recommended that the City of Seattle develop a park at the location of Alki Beach Park in his 1903 "Comprehensive Plan of Parks and Parkways." He intended it as the terminus of Schmitz Boulevard, which would extend from Alki Beach up the hill, through Schmitz Park, and connect with a "West Seattle Parkway." The boulevard was developed through the park, but it is now maintained as a trail.
The Olmsted Brothers provided drawings to the Parks Board identifying a location of a bathhouse for the bathing beach, just to the east of 62nd Avenue Southwest, where the Alki Bathhouse stands today, though it is used as an art studio.
