Marine Drive Stormwater LID Retrofit

Project Status (October 17, 2019)

The contractor will begin work at the Marine Drive and Dora Avenue site on October 21, 2019. Marine Drive will be reduced to alternating one way traffic with flaggers during working hours from October 21st to October 25th.  Additionally intermittent lane shifts on Marine Drive and on Dora Avenue should be expected from October 28th to November 1st. The contractor will be installing an underground stormwater system and will temporarily patch the trenches with cold mix asphalt. At the end of the project, and when weather permits, the contractor will return to the site to mill over all of the disturbed areas and will place new asphalt. 

Once work is complete at Marine and Dora crews will move to the site that is just south of Kelly Drive on Marine Drive. Work at that site will take approximately 2 weeks and then crews will move to the final site at Kitsap Way and Oyster Bay Avenue.   

Project Overview

Oyster and Ostrich Bays have water quality problems that are exacerbated by the discharge of untreated stormwater. This project will install one Modular Wetland System (MWS) & 250’ of infiltration trench on Marine Drive at Dora Ave, and two Modular Wetlands Systems, south of Kelly Rd, to treat runoff prior to discharge into Oyster Bay. Modular Wetland units provide stormwater treatment, and will reduce fecal coliform in runoff from 34 acres that including 1.34 miles of urban roads and 17.4 acres of pollution generating impervious surface. An additional MWS will be installed on Kitsap Way at Oyster Bay Inn to treat runoff from 1.5 acres of impervious area on Kitsap Way.  

Pape & Sons Construction was awarded the bid for the construction of the Marine Drive Stormwater LID Retrofit project.     


The 2019 budget for this project is $ 1,067,747. The City was awarded a $664,747 State Ecology grant to complete construction of the system, and the remaining funds were budgeted from the Stormwater Capital Fund. Design was funded by a separate Ecology grant in 2015.  


Construction will begin on October 21st at Marine Drive and Dora Ave, and will take a few weeks at each site. Construction will continue through the end of the year, weather permitting.
