Marine Drive Stormwater LID Retrofit

Project Status (November 25, 2019)

The contractor will begin working on installing the final stormwater vault on Kitsap Way just west of Oyster Bay Avenue (adjacent to Oyster Bay Inn). The work is expected to take about 3 weeks and will require the closure of the west bound right lane of Kitsap Way between the hours of 7:30 am to 3:30 pm. A bike lane and sidewalk detour will be in place.  

The contractor has completed installation of stormwater vaults at the Marine and Dora site and at the Marine and Kelly Drive site. During a window of exceptional November weather the contractor was able to repave the disturbed areas. A few punch list items of work remain at the sites, along with the testing and activation of the stormwater units, but otherwise work is complete on Marine Drive.  

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 began 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.
