Alki Seawall Project at Emma Schmitz Memorial Overlook


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 under Section 103 of the Rivers and Harbors Act of 1962, as amended.  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.


The sponsor of the project is Seattle Parks and Recreation.
