Kitsap Lake Projects

Kitsap Lake Algae Control and Aquatic Vegetation Management  

The goal of this ongoing project is to improve water quality of the lake and provide a safe environment for all lake users including people, fish, wildlife, and pets. Improved water quality has a significant positive impact on downstream users including shellfish at the Chico Creek outlet in Dyes Inlet. By using safe products and processes to remove phosphorus, and harvesting excess submerged vegetation we are protecting the lake and habitat without damaging sensitive fish stocks, or vegetation species.  This project began in 2019 and is ongoing. 

Francis Drive Outfall Stormwater Retrofit 

This project was developed as part of the City’s SMAP, click here Version Options Stewardship Projects Headline to learn more, and provides increased capacity and enhanced stormwater treatment. This project rerouted storm flows to better utilize the two existing stormwater outfalls to convey the anticipated 100-year storm from this basin into Kitsap Lake.  Included in the project is the installation of stormwater treatment vaults which will treat the over 64 acres of this basin  This includes the removal of fecal coliform, suspended solids, dissolved copper, dissolved zinc, and total phosphorus from the stormwater.

This project was completed in 2025.

Kitsap Lake Park Stormwater Treatment

As part of the improvements to the Kitsap Lake Park Facilities, the Stormwater Program partnered with the Parks Department to fund the installation of one BioPod biological filtration system to treat runoff from the parking lot prior to discharge into the lake. The BioPod provides basic, enhanced, and phosphorus treatment, and reduces fecal coliform in runoff from the parking lot, a pollution generating impervious surface.  This supports the on-going effort to improve water quality in Kitsap Lake. This project was completed in 2025.

Kitsap Way and Dockside Stormwater Retrofit

In the City’s continuing effort to improve water quality for Kitsap Lake, this project will provide treatment at four outfall locations that are currently untreated. The treatment will consist of installation of TAPE GULD approved systems at three sites in Osprey Circle and one on the north side of the intersection of Kitsap Way and Northlake Way. Treatment will be for suspended solids (TSS), dissolved copper, dissolved zinc, and total phosphorus.  

The City obtained funding from a Department of Ecology grant to complete final design and construction of the project. Construction began on October 27, 2025 and is anticipated to be completed by April 2026.

Northlake Way Culvert Replacement 

The goal of this proposed project is to improve fish passage for coho, chum, East Kitsap DIP steelhead, cutthroat, and residential trout. Bremerton received a grant for preliminary design in 2018 from Washington’s Recreation and Conservation Office. 

Oyster and Ostrich Bay Projects

Beach Sewer Main Decommissioning Projects

 including Oyster Bay Beach Sewer Upgrades. Many waterfront homes in Bremerton were connected to sewer mains buried along the shores of these water bodies. These types of sewers are difficult to access and maintain and occasionally surcharge during heavy rains. The City is in the process of eliminating/reducing the beach sewers over time.  A section of beach sewer along Oyster Bay was decommissioned in 2022, and the next section is scheduled to be completed from 2026 to 2028. 

Ostrich Bay Creek Stormwater Treatment Project  

BioPod Biofiltration pods treat stormwater from 6.4 acres of urban roadway and parking lot plus 8.9 acres of roof tops, lawn and forested surfaces. This project will help Ostrich Bay and Dyes inlet meet the fecal coliform TMDL by improving water quality in Ostrich Bay. The project location was multiple sites in the area between Auto Center Way, Bruenn Ave, and Burwell Street. This project was completed in 2022.

Ostrich Creek Basin Stormwater Improvements: Kitsap Way  

Improvement of Kitsap Way including replacement of an existing concrete box culvert with a precast reinforced concrete three-sided culvert was completed in 2022.

Oyster Bay Stormwater Improvements

The City installed three Modular Wetland Systems and an infiltration trench on Marine Drive and one Modular Wetland System on Kitsap Way in 2019.

Price Road and Brentwood Drive Culvert Replacements

Improvement of two Ostrich Creek crossings at Price Road and Brentwood Drive by replacing the outdated culverts with precast concrete voided slab girder bridges was completed in 2022.

Port Washington Narrows Projects

Evergreen Park Shoreline Reconstruction

Design for this restoration project is complete and the City is seeking funding for construction. Long term groundwater monitoring has been ongoing since 2013.

Lebo Blvd Modular Wetlands (MWS) 

Ten MWS were installed along Lebo Blvd in East Bremerton in 2018 to remove pollutants from stormwater before it reaches Port Washington Narrows.

Stormwater Demonstration Park, Anderson Cove 

The Lillian and James Walker Stormwater Demonstration Park at Anderson Cove was completed in 2013 with a $1.6M Ecology grant. This ¾ acre pocket park provides stormwater treatment and serves as a low impact development techniques demonstration site. 

Pine Road Stormwater Basin Improvements

This project includes outfall repair, flood mitigation, and marine shoreline cleanup. The first phase of project work in upland areas is complete. A second phase to replace the failing outfall at the intersection of Sheridan Road and Lebo Boulevard is scheduled for construction summer 2024.

Sinclair and Dyes Inlets Projects

Anderson Creek Dam Removal

In the 1920’s the City of Bremerton constructed two concrete and earthen dam structures on the east and west forks of Anderson Creek for a surface drinking water supply. The structures were abandoned in the 1960’s and were listed by the Washington Department of Fish and Wildlife as being complete (100%) fish passage barriers.

This project and restoration of Anderson Creek will open access to over 3 miles of habitat for multiple salmonid species, including ESA listed Puget Sound steelhead.     

Construction was completed on January 27, 2025.

Parish Creek Fish Barrier Removal 

This project combines fish barrier removal and flood mitigation at Parish Creek. Replace the existing culvert the crosses W Belfair Highway at Parish Creek with a 2-lane bridge. The bridge and reconstructed stream reach will provide for passage of native fish including coho and steelhead. Parish Creek Fish Passage Barrier Removal project has been selected in 2024 by the Department of Fish and Wildlife’s Brian Abbott Fish Barrier Removal Board to receive FHWA Promoting Resilient Operations for Transformative, Efficient, and Cost-Saving Transportation (PROTECT) program funding. 

Preliminary design was funded by the stormwater utility fund. PROTECT grant funding has been obtained for final design and construction. ($567k stormwater utility fund, $2,266k PROTECT Grant). Sixty percent design plans are anticipated in June 2026 and will be posted to the project website. 

Beach Sewer Main Decommissioning Projects

The Manette beach sewer between E16th and E11th Streets is the next beach sewer main scheduled to be decommissioned.  Many of the residences and commercial buildings along the water in Manette between E 16th Street and the Manette Bridge are connected to a sewer main buried under the beach. This sewer main is difficult to access and maintain and can surcharge during heavy rainstorms. To address this issue, the City will be installing an upland sewer system and abandoning the beach main and lateral connections.
