Lowman Beach Park Seawall

Updated: September 9, 2021

Late Summer 2021

Seattle Parks and Recreation awarded the construction contract to Mike McClung Construction for the Lowman Beach Park Shoreline Restoration project. The contractor is anticipated to mobilize on site after Labor Day and the park will be partially closed. Closure includes beach access, tennis court and trail access. Public access to a portion of the lawn and playground area will be maintained. See larger photo of closure area.

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.


Planning & Design: 2017 - May 2021
Bidding: Late Spring - Late Summer 2021
Construction: Late Summer 2021 - Spring 2022

Project Description

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.

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.

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.
