City Beach Drive Culvert Replacement

Island County, WA

Harmsen completed civil engineering services for an emergency culvert replacement project in Island County. The project provided for the removal of a failed corrugated metal pipe and installation of a new 72” DuromaxxTM polyethylene pipe.

Culvert and Water - The culvert was installed in a corrosive salt water environment at a road crossing between two lagoons. The project included coordination with the local water district for shutoff of a watermain that was replaced as it was exposed during the excavation process.

Civil Design - Our work involves design of the Temporary Erosion and Sediment Control (TESC) measures, including:

  • Coffer dams and pumping
  • Installation and backfill for the new culvert
  • Roadway reconstruction
  • New walkway for the local residents

Coordination - We worked closely with the County’s Managing Engineer and coordinated with the utility owners.

Landscape Architecture - The project also required us to provide a planting plan for both ends of the culvert pipe and quarry spalls.
