REQUEST FOR PROPOSALS
S 104th St. Shoreline Restoration + Duwamish Hill Preserve Phase 3
PROFESSIONAL DESIGN, PLANNING AND ENGINEERING SERVICES
PROJECT DESCRIPTION:
This RFP is for site investigations, site analysis and preliminary design for two separate and distinct City
of Tukwila capital improvement projects:
• S. 104th St. Shoreline Restoration Project
• Duwamish Hill Preserve Phase 3
The two projects are similar in that they are both shoreline restoration projects located along the right
bank of the Duwamish River and involve consideration of local roads and utilities within the shoreline
area. No site investigations or design work has been completed for either project site. Given these
similarities, the City estimates that the expertise needed to provide the requested services for these two
projects is similar and is opting to issue a single RFP for both projects.
S. 104th Street Shoreline Restoration Project:
The purpose of this project is to improve shoreline conditions along approximately 1,000 lineal feet of
Duwamish River shoreline. The riverbank is located on an outside bend in the river and is lightly
vegetated with mostly non-native low level vegetation and armored with angular material. S. 104th
Street is a short, local connector road that provides access to the backside of three private commercial
properties and redundant roadway access between East Marginal Way South, the three properties, a
downstream Boeing property, and the currently closed and privately owned bridge (Boeing) across the
Duwamish River. The road is exceptionally close to the river with jersey barriers separating the road and
steep riverbank.
This project was initially identified in the 2003 City of Tukwila Surface Water Comprehensive Plan and is
admitted into the 2021 Update to the WRIA 9 Salmon Habitat Plan. City staff have had discussions
about potentially vacating or abandoning the road, and the WRIA 9 Salmon Habitat Plan entry
contemplates utilizing additional properties to a create a more substantial off -channel habitat project.
The property owners have not been contacted and stakeholder outreach has not been conducted.

Duwamish Hill Preserve Phase 3:
The purpose of this project is to improve shoreline conditions along approximately 700 lineal feet of
Duwamish River right bank shoreline. Duwamish Hill Preserve is a roughly 10-acre city park and nature
preserve. The park has been owned and managed by the city for approximately 25 years, following land
acquisition led by Forterra. At that time, the city commissioned a park master plan, and has since
worked to build out trails, gathering places and planting as identified in the plan. The remaining piece of
the masterplan is the shoreline setback component of the project, Phase 3. The City and Forterra
recently acquired two small parcels of land along S 115' St, expanding the park footprint per the master
plan.
S 115th St, a local arterial and critical community connector, runs through the shoreline area, separating
the park from the Duwamish River. The space between the road and the river is an unimproved, mostly
dirt and gravel area used for informal parking and occasionally as a location for illegal dumping.
This project was initially identified in the 2003 City of Tukwila Surface Water Comprehensive Plan and
appears in the WRIA 9 2021 Salmon Habitat Plan Update. While a road setback is envisioned in the
master plan, the ultimately selected design may differ depending on a variety of factors, including
affordability, that will be analyzed as part of this work.
