Lowman Beach Park Seawall

Updated: May 18, 2021

Spring 2021

The goal of this project is to remove the remainder of the failing seawall and continue shoreline restoration work that began when the south half of the seawall failed in the mid-1990's.

Seattle Parks and Recreation hired Environmental Science Associates to continue the design process that they began in 2017 with a feasibility study. The design will take into consideration both the habitat benefits of the seawall removal, improved public access to the shoreline and the coastal engineering ramifications of that seawall removal. Given the design constraints of the project, the existing tennis court will be removed. A remnant of Pelly Creek that currently flows under the park and through the existing seawall will be daylighted as part of the project.

Lowman Beach Park will be partially closed during construction including closure to the beach access, tennis court and trail access. The project will maintain public access to the lawn and playground area.

Location

Lowman Beach Park, 7017 Beach Drive SW, 98136

Budget

Funding for the feasibility study and design of the project came from State and local grants: $400,000 from the King County Flood Control District's Cooperative Watershed Management Fund (CWM) in two grants and $200,000 from the State's Salmon Recovery Funding Board. We received an additional $450,000 from King County's CWM Fund and $500,000 from the State's Aquatic Lands Enhancement Account to fund the construction of the project.

Schedule

Planning & Design: 2017 - May 2021
Bidding: May - June 2021
Construction: July 2021 - March 2022

2019 Lowman Beach Park 30% Design Plans 

In September 2019 Seattle Parks and Recreation (SPR) determined that the project does not have a probable significant adverse impact on the environment. An environmental impact statement (EIS) was not required under RCW 43.21C.030(2)(c). This decision was made after review of a completed environmental checklist and other information on file with SPR. The Determination of Non-Significance (DNS) was issued on September 12, 2019 and is available below.   In February 2019 SPR presented the preliminary design (30% design) for the Lowman Beach Park Restoration and Seawall Removal project. The preliminary design takes 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, the existing tennis court will be removed. A remnant of Pelly Creek that currently flows under the seawall will be daylighted as part of the project.
