Soil borings and sampling at Emma Schmitz Memorial Overlook

The U.S. Army Corps of Engineers (Corps), the City of Seattle, and Seattle Parks and Recreation (SPR) are collaborating on the Emma Schmitz seawall repair. Together we are ensuring a successful cost-sharing program to restore shoreline protection at Emma Schmitz Memorial Overlook in West Seattle. SPR entered into a Project Partnership Agreement with the Corps for the replacement of the seawall. The Corps is responsible for the design of the seawall, and one of the steps in the design process is to take soil borings to inform the final design. Drill equipment will be on site for several days starting the week of June 4.

Built circa 1927, the 450-foot stretch of seawall supports important City and County infrastructure, including a 54-inch sewer main, various Seattle Public Utilities drainage and wastewater lines, and Beach Drive Southwest road. The seawall is badly deteriorated, with a 30 percent chance of failure in the event of severe storm or tidal conditions. The new seawall will be built approximately 2 feet seaward and 2 feet higher than the existing wall, thus significantly improving the grade of this scenic viewpoint for the enjoyment of park users as well as ensuring long-term stability.

The implementation cost of the recommended plan is estimated to be more than $2 million, and will be cost-shared with 65 percent federal funds and 35 percent non-federal funds. The non-federal sponsor, SPR, is responsible for all lands, easements, right-of-ways, relocations, and/or disposal areas which are controlled by the sponsor.

The Corps is designing the seawall, and SPR will be designing the park amenities on top of the wall area. SPR will be holding a public meeting to provide information and gather input on these park amenities.

Community invited to Lowman Beach Park seawall meeting

Seattle Parks and Recreation (SPR) invites the community to the Hall at Fauntleroy at 6:30 p.m. on Wednesday, May 31 to learn about the Lowman Beach Park seawall and provide input on design options. The Hall at Fauntleroy is located at 9131 California Ave. SW.

Lowman Beach Park is a neighborhood park on the water located just north of Lincoln Park at 7017 Beach Dr. SW. At this meeting, SPR will present the project background, analysis of the coastal processes (wind, waves, tides, sediment transport/littoral drift) and design options, as well as gather community input.

The Lowman Beach Park seawall is failing and needs to be removed or replaced. As visitors to the park have seen, the existing seawall is slowly falling over towards the water. It is SPR’s goal to remove the remaining seawall and continue the shoreline restoration work that began when the south half of the seawall failed in the mid-1990s.

We hired Environmental Science Associates (ESA) as a design consultant to undertake a feasibility study to look at options for removing the seawall, taking into consideration both the habitat benefits of the seawall removal and the coastal engineering ramifications of that seawall removal. Given the design constraints of the project, it is likely that the existing tennis court will remain in place.
