Alki Seawall Project at Emma Schmitz Memorial Overlook

The U.S Army Corps of Engineers, Seattle District, has partnered with the City of Seattle Parks and Recreation Department 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 the City of Seattle Parks and Recreation Department.

·         Reduce the risk of physical damages to public utilities and transportation infrastructure resulting from coastal storm events, storm-induced waves, and tidal fluctuations.
·         Reduce the risk of erosion and loss of public lands due to storm damages.
·         Reduce the risk of environmental impacts resulting from a sewer main failure.
·         Reduce annual operations and maintenance costs.
·         Reduce the risk of potential transportation delays and other emergency costs to residences, businesses and government entities resulting.

The project is in the design phase.  Construction could occur in Fiscal Year 2019 subject to availability of funds. Exploratory drilling took place in the summer of 2018.
