As of October 2024
Phase: 60% Design

Project Overview

Erosion is occurring near lower Storm Creek between 17th Place NW and the BNSF Railway corridor along the Puget Sound shoreline. A public-private partnership has been formed for a Storm Creek Erosion Management Project (Project) to install improvements to manage the risks from the erosion as it threatens both public infrastructure and private properties. A Project team of professional consultants led by the City is currently developing construction plans for these improvements. 

Schedule

Spring 2022 - Spring 2023: Preliminary Design
Spring 2023 - Spring 2025: Final Design & Permitting
Summer 2025: Construction (Pending permitting timelines)

Funding

Project costs for design, permitting, and construction totaling up to $1,000,000 are funded by:

  • King County Flood Control District (KCFCD) Flood Reduction Grant
  • City's Water Management Capital Fund and the Wastewater Capital Fund
  • Private property owner projects partners

Downcutting - Slot Canyon

Background

Storm Creek has a .75 square mile basin area and outfalls to Puget Sound just south of Richmond Beach Saltwater Park. Land use in the basin is mostly residential.

Starting decades ago, erosion along Storm Creek within the steep bluff along the Puget Sound shoreline has cut a deep "slot canyon". Around 1995, the Ronald Wastewater District (RWD) installed large concrete blocks in this part of the stream as erosion protection for an 8-inch diameter sanitary sewer main crossing below the creek.

The Innis Arden Club owns the property through which Storm Creek flows at this location. For a long time, the homeowners on both sides of the "slot canyon" have expressed concerns with ongoing and potential impacts of this erosion on their properties.

The City of Shoreline evaluated the overall basin and lower Storm Creek erosion issues in 2012 under the Storm Creek Basin Plan. Based on the Basin Plan's recommendations, the City did annual Storm Creek land surveys from 2014 to 2018 to measure and monitor the erosion. 

In 2017-2018, as part of a cooperative effort between the City and Project Partners (the Innis Arden Club, the adjacent private property owners, and RWD (assumed by the City in April 2021)), an engineering consultant developed a conceptual solution to "tightline" Storm Creek through the "slot canyon" erosion area. The concept proposed using over 100 linear feet of 36-inch diameter pipe and three large manhole-type structures to convey streamflow through the erosion area, over 1,000 cubic yards of rock to fill the narrow ravine above the pipe, and full site restoration - including stream restoration improvements upstream and downstream of the new pipe and plantings.

City Staff, with the support of Project Partners, applied for and received a competitive King County Flood Control District (KCFCD) Flood Reduction Grant. Following the receipt of grant funding, the City and Project Partners developed a funding agreement for the remaining cost of the Project not covered by grant funds. 

The funding agreement establishes the Project as the City's to manage through design, permitting, and construction, subject to typical City project requirements, standards, and best practices. Project Partners contributions include funding, easements, and feedback at key project milestones.
