This project will evaluate about 6,000 feet of roadside ditches and culverts along Semiahmoo Drive. The project will upgrade the drainage system as needed to reduce the frequency of standing water on the roadway and improve the drainage in this area.

Project Benefits

  • Improve safety
  • Replace failing system

The roadway culvert under Semiahmoo Drive was found to be undersized. The project will replace the existing 12-inch diameter culvert with a new 30 inch diameter pipe. The length of the new pipe is approximately 165 feet and include some minor ditch regrading.

Project Schedule

The project is currently at the 90% design level and project construction is planned for 2022 and should take about five weeks to construct.
