Herring's House Park (Tualtwx) – Shoreline Restoration
Updated: April 21, 2026
Spring 2026
Environmental Science Associates (ESA) consultant completed a study of the shoreline habitat at the park in 2024. The study identified the likely reasons for the lack of fish usage for Seattle Parks and Recreation (SPR), partners and stakeholders to evaluate and select a design option that will promote improved use of the habitat by juvenile salmon. The goal is to promote a stronger salmon population in this historic Duwamish waterway.
In the early 2000s, SPR invested in this area's habitat by restoring the shoreline vegetation and creating a tidal inlet for fish migrating in and out of the waterway. We are now looking to help this habitat provide greater value for the local wildlife.
We now have funding through a grant from King County’s Cooperative Watershed Management program to begin the preliminary design of habitat improvements based on the concept study and stakeholder outreach completed in 2024.

Project Description
Juvenile salmonids access the shallow saltwater marsh at Herring’s House Park on the Lower Duwamish, but the estuary area is only accessible at higher tidal elevations and the access point to the marsh/estuary area is likley be too narrow to attract significant use by large numbers of juveniles as they out-migrate. Based on the Concept Study, Environmental Science Associates (ESA) will prepare a preliminary design that will provide better access for juvenile salmonids to the marsh/estuary area at a broader range of tidal elevations.
