The City of Poulsbo, in collaboration with the Washington State Department of Transportation (WSDOT) and Kitsap County, is moving forward with the start of construction on improvements at the intersection of Johnson Way and SR305. The City Council authorized the award of the contract to ACI-Active Construction Inc., on June 10, 2020. Construction began mid-January 2021. This project will improve traffic mobility and provide safer access to SR305 with the construction of a roundabout at the new intersection of Johnson Road and a non-motorized tunnel crossing at SR305. A newly constructed road, Johnson Parkway, will be created by realigning the south segment of Noll Road ¼ mile south of Poulsbo Elementary School to the newly constructed roundabout at SR305. The project is expected to be completed within a year and a half of construction start. For more details, visit the opens in a new windowproject page.


As part of the City operations, sanitary sewer lines and manholes are maintained and replaced when they have reached the end of their useful lifetime. There are areas of the City with old sewer which has a history of issues including root intrusion, degraded pipe, and groundwater infiltration. The City has developed two sewer rehabilitation projects to extend the life of these existing sewers without needing to fully replace the sewer.

The two projects are called: SR305 Manhole Rehabilitation Project CN2019-02 and Raab Park, Swanson Way NE, and 11th Ave NE CIPP Lining Project CN2019-03.

SR305 Manhole Rehabilitation Project

Last winter the City successfully completed phase 1 of the Central Interceptor Rehabilitation project which included re-lining the main sewer trunkline leaving the City along SR305. The second phase of this project is to rehab the manholes by cleaning, grouting, and sealing to prevent degradation and groundwater infiltration. This project extends between Tollefson along SR305 to Johnson Road, and along Johnson Rd through undeveloped property to the Deer Run neighborhood. Thirty five sewer manholes will be rehabilitated as part of this project.

Work along SR305 will be completed during the night in order to comply with WSDOT permitting and residents will not experience an interruption to sewer services as a result of this project. The contractor has 65 working days to complete the work.

Raab Park, Swanson Way Ne, and 11th Ave NE CIPP Lining Project

Concrete sewers in the vicinity of Raab Park, Swanson Way NE, and 11th Ave NE will be lined with Cured In Place Pipe or CIPP Lining. The idea is to slip a liner into the existing sewer, expand it, and cure it in place thereby creating a pipe within a pipe. The newer pipe is stronger and protects from groundwater and root intrusion as well as reduces joints and other areas that can potentially cause sewer backups. This lining method is also known as trenchless sewer repair as it is does not require the street to be torn up to replace the existing sewer.

The CIPP Lining Project will line approximately 1,860 linear feet of concrete pipe on 11th Avenue, Raab Park, and Swanson Way. Residences in this neighborhood will be affected by this project for a short time and will be notified in advance of the work. A sewer service interruption will be required from some residents in order to complete the project and avoid sewer backups. The contractor has 40 working days to complete the work.


The Finn Hill Road Shared Use Path project will construct approximately 4,300 ft of 10-ft wide shared use path with 2-ft gravel shoulders on NW Finn Hill Road and Rhododendron Lane NW between Olhava Way NW and Vinland Elementary School in Poulsbo. The path will be pervious asphalt and will be on the north side of NW Finn Hill Road and the east side of Rhododendron Lane NW.  An approximate 400-ft section of path will be constructed as an elevated 8-ft wide boardwalk to avoid wetland impacts.  Curb ramps, pedestrian crossing signs and cross walk markings will be installed at the intersections of NW Finn Hill/Urdahl Road and NW Finn Hill Road/NW Rude Road.  Approximately 4,200-ft of new curb and gutter on the north side of NW Finn Hill Road and the east side of Rhododendron Lane NW will be installed between the travel lane and the landscape buffer/boardwalk/multi use path.  Street lights will be mounted on existing utility poles at pedestrian crossing locations.

Phase one of the project will be to install illumination on existing utility poles and to add one new pole along Finn Hill.

Phase two of the project will be the construction of the shared use path.

This corridor improvement will connect SR305 to NE Lincoln Road via Noll Road, Languanet Lane and Maranatha Road. The improvements will include street lighting, sidewalks, and shared use path improvements throughout the corridor. The broader Noll Road Corridor Improvements is being broke into a compilation of smaller projects. The City applied for funding in March 2020 for completion of the north segment, Languanet Lane. The south segment project will realign Noll Road from ¼ mile south of Poulsbo Elementary School to SR305 (new roadway Johnson Parkway). It will also include a roundabout at the new intersection of SR 305 and Johnson Road. The right of way acquisition process for the south segment is complete and construction could begin as early as September 2020 or at the latest March 2021.


This project consists of installation of a new treatment plant which will filter manganese out of the water supply.  Manganese is a naturally occurring mineral that causes staining and brown water or sediment in the system.  The City regularly flushes our systems to remove the sediment.

A pilot test for a treatment system is scheduled for late May 2019 – similar to a pilot test that was performed for the Lincoln Well #2 project.  Following the results, the City’s consultant will design a new treatment plant for the Westside Well.  Construction is anticipated to occur in late 2019 to 2020.


South Fork Dogfish Creek:  The City is working on 2 projects with the Department of Ecology for the South Fork Dogfish Creek.  The first project will restore 100 feet of degraded stream channel, flood plain and riparian buffer on City property between 8th Avenue and Centennial Park.  A new stream channel will be constructed adjacent to the existing degraded channel below 8th Avenue.  The new channel will include streambed aggregate, large wood debris and riparian vegetation.

The second project is for design of a project to improve water quality in Dogfish Creek and Liberty Bay through the design of green infrastructure and Ecology-approved TAPE facilities in the South Fork Dogfish Creek basin.  The project will be designed to remove total suspended solids, dissolved copper and zinc, and total phosphorus.  The facilities will also reduce flows to Dogfish Creek by increasing stormwater infiltration.


Liberty Bay Waterfront Trail
This project will extend trails in American Legion Park to the existing trail system in Fish Park. Feasibility studies and pre-design work on this project are ongoing. The viability of the project is promising and the City anticipates more forward progress on this project in the coming months.



This project constructed a bioretention swale on Fjord Drive near the Poulsbo Yacht Club and 6th Ave, as well as a stormwater treatment vault at the Poulsbo Middle School campus.

Bioretention swale along Fjord Dr


Forest Rock Lane, an important neighborhood collector in our City Network, was built 20 years ago and is in need of an upgrade.  Steepness of the road, subsurface water flow, road base and asphalt thickness have all been contributing factors to condition of the road.  This project will rebuild the road base, install trench drains, and thicker asphalt to improve the road. The road will be upgraded from the Central Market entrance to Caldart Avenue.

This is the first Full Depth Reclamation type of project for the City. The existing road and base is pulverized and used to build the new road section on top of it.  This means the project reuses material, reduces the work and material required by the contractor and shortens the duration of the project.   The project will also include drainage enhancements, ADA upgrades, installation of a radar speed sign, and channelization of the road to slow down traffic. This project was completed in August 2019.


The City of Poulsbo completed constructing improvements to the Fjord Drive/Harrison Street Sewer/Water/Storm System.   The water main was replaced and upsized – adding more capacity and improving fire flow. The sanitary sewer system was upgraded and moved from its previous shoreline location and was rerouted down Fjord Drive up to Harrison.  The storm sewer system also received minor upgrades – improving drainage.  Additionally, Cascade Natural Gas will be installed new gas lines.  All utilities were aging and due for upgrades.  The driving lanes were replaced on Fjord Drive and on the west side of Hostmark Street within the project limits and there were ADA upgrades on Hostmark Street.  The project was completed in Fall 2018.


The City of Poulsbo’s Central Interceptor, located along SR305, conveys the City’s wastewater to Lemolo, where it enters Kitsap County’s collection system.  The Central Interceptor is critical to the City as it conveys all the wastewater from the City to the County.  In 2016, video inspection of the Central Interceptor showed the 18” diameter reinforced concrete pipe to be deteriorated and in need of rehabilitation and/or replacement.  The City worked with RH2 Engineering to design a trenchless cured-in-place-pipe (CIPP) rehabilitation strategy for approximately 4,962 linear feet of pipe.

A cured-in-place pipe (CIPP) is one of the most widely used rehabilitation methods used to repair existing pipelines. CIPP is a jointless, seamless, pipe-within-a-pipe with the capability to rehabilitate sewer pipes.   The City contracted with Insta-Pipe to install an ultra violet (UV) cured pipe liner. The project extended from Sol Vei to Johnson Road on the west side of SR305.  The CIPP was successfully installed and the project was completed in early 2018.
