This program repairs or replaces short sections of aging or damaged stormwater pipes across Shoreline to reduce flooding and protect infrastructure. This work proactively maintains the City’s 145 miles of stormwater pipe through inspection, repair, and replacement. Learn more about the Pipe Repair and Replacement Project Program, including work planned for this year, here. 

This program addresses minor public drainage issues by installing berms, catch basins, pipes, and other small improvements in the public right-of-way. Projects are typically identified through resident reports or field inspections. Learn more about this program here.

This new program will use green stormwater infrastructure, like roadside rain gardens and permeable pavement, to capture, soak in, and clean polluted rainwater. Greenworks projects support community priorities from the 2025–2030 Surface Water Master Plan, including protecting streams, preparing for climate change, and making Shoreline greener. Because the program is new, all projects are in early planning stages. More information will be shared soon.

This new program will restore damaged streams and surrounding areas to improve habitat and water quality for wildlife such as salmon, river otters, and orcas. Restoration projects will focus primarily on planting and protecting native vegetation along impacted streams. These projects support community priorities from the 2025–2030 Surface Water Master Plan.

In 2026, we’ll complete a study to find the stream sections where restoration will make the biggest difference. The results will help guide where we start the work.

This new program adds surface water improvements to other City projects, like sidewalks or wastewater upgrades, helping protect our community and environment. By combining stormwater improvements with other planned City projects, we can save time, reduce disruption, and use funds more efficiently. These projects will support different community priorities from the 2025-2030 Surface Water Master Plan, including reducing flooding and drainage problems, protecting streams, preparing for climate change, and installing new drainage systems where needed.

This project will replace and upgrade Pump Station 30, including new pumps, controls, and improvements to the adjacent detention pond, to ensure the station continues to prevent flooding in the Ridgecrest neighborhood. Many components of the station have reached the end of their operational life, and these upgrades are needed to maintain reliable service.

This project will improve drainage by enhancing existing ditches with amended soils and new vegetation to filter and soak in runoff. These improvements will reduce flooding on the road and nearby properties, while also protecting Little’s Creek from erosion and pollution. The project areas include:

• 10th AVE NE and 8th AVE NE between NE 165th Street and NE 175th Street
• NE 174th Street between 8^th AVE NE and 10th AVE NE

This project will reduce flooding along 25th Avenue NE and improve habitat for Ballinger Creek by daylighting the creek and upgrading drainage infrastructure. This work will include replacing the NE 195th Street culvert. Work is in the planning and design phase, with ongoing coordination with neighbors, agencies, and funding partners. Construction is not yet scheduled.

Phase 1 of the project removed the Hidden Lake dam to restore natural stream flows in Boeing Creek. This restoration eliminates the costly sediment removal previously required to maintain Hidden Lake, allowing sediment to flow downstream and naturally restore deltas at the mouth of Puget Sound.

Phase 2, planned for 2026, will replace culverts under NW Innis Arden Way. The Boeing Creek Restoration Project enhances public safety by reducing flood and erosion risks, restores fish and wildlife habitat, improves water quality, and eliminates ongoing sediment maintenance costs.

This project will design and construct a new culvert crossing at Barnacle Creek along 23rd Place NW, including necessary storm drains, to address long-term stream erosion and roadway embankment stability concerns. It responds to regulatory requirements as a result of emergency repairs made in 2018, with design underway and construction anticipated in summer 2026.

The Storm Creek Erosion Management Project is a public-private effort to address ongoing erosion near lower Storm Creek, threatening both public infrastructure and private property along the Puget Sound shoreline. The City and a team of professional consultants are currently developing construction plans for improvements to manage these risks. This project has faced significant permitting challenges, resulting in delays to the planning and construction timeline.

The 25th Avenue NE Ditch Improvement Project was created to resolve persistent drainage issues along 24th and 25th Avenues NE. The existing half-pipe system frequently clogs and causes water to overflow, leading to roadway flooding and erosion problems.
