Emma Schmitz Seawall replacement work set to begin July 15
The U.S Army Corps of Engineers, Seattle District, has partnered with Seattle Parks and Recreation to design and implement a coastal storm damage reduction project to replace the existing 500-foot-long seawall at Emma Schmitz Memorial Overlook, 4503 Beach Dr. SW, Seattle, WA 98116, that was constructed in the 1920s and has experienced significant erosion and damage from storm events.
The work is set to begin July 15 and some of the work will take place in the evening hours to take advantage of lower tides.
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 recommended design would provide protection that addresses damages caused by coastal storm events in Puget Sound. 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 project site is the Emma Schmitz Memorial Overlook in West Seattle.
