Duwamish Waterway Park Expansion
Updated: July 7, 2026
Summer 2026
The site is a 1-acre property next to Duwamish Waterway Park that was purchased in 2021. In 2024 and 2025, Seattle Parks and Recreation worked with community to understand needs and wants for a potential expansion of the Duwamish Waterway Park.
Two conceptual designs were developed and presented to community in July 2025. The preferred alternative design included an expansion of greenspace, diverse plantings along the shoreline to restore critical shoreline habitat and a gathering/picnicking area associated with the neighboring play area.
