Announced this morning:
The Seattle District, U.S. Army Corps of Engineers, awarded a $3 million contract September 27 to Redside Construction based in Bainbridge Island to replace an existing seawall in West Seattle.
The project will replace the existing 500-foot-long seawall at Emma Schmitz Memorial Overlook, 4503 Beach Dr. SW, that was constructed in the 1920s and has experienced significant erosion and damage from storm events. We anticipate construction in mid-2020.
The new seawall will be a “soldier pile” (system of vertical piles spaced at a regular interval with material in between to create a wall) design, built a few feet seaward and a few feet higher than the existing seawall, and equipped with safety handrails that the current seawall lacks. This design will minimize the impact on the beach, address rising sea level concerns and create better contours for the restoration landscaping on the landward portion of the overlook area.
The Army Corps has partnered with Seattle Parks and Recreation to design and build this coastal storm damage reduction project under Section 103 of the Rivers and Harbors Act of 1962. Coastal storms and erosion continue to threaten public infrastructure located in and around the project footprint, including a 54-inch King County sewer main, a main public arterial, City park property, and other underground utilities.
The Seattle Parks project page is here; our coverage of a Q&A community meeting about the project back in July is here. Community comments were first solicited in 2014, when the project was estimated to cost $2.3 million.
