Birch Bay stormwater project works around berm construction


Whatcom County Public Works has finished the first phase of the two-phase Harborview Road and Birch Bay Drive stormwater project last month.

Interwest Construction, Inc., the county’s contractor, installed a new outfall pipe and catch basin on the water side of Birch Bay Drive at the intersection of Harborview Road. Phase 2 of the $855,000 project will be completed in the fall.

Project manager Kevin Thompson said phase 1 of construction and work during berm construction went smoothly. “We were able to coordinate with Granite Construction, and the other sub-contractors, so that there were no issues,” he said.

Thompson said the county was pushing to get the first phase of the project complete before Granite Construction finished the cement work on the Birch Bay berm project. This way, crews would not have to dig up new concrete to place the outfall pipe and catch basin that cuts directly through the berm.

According to the project website, in phase 2 of construction – September 8 through October 25 – Interwest Construction crews will install a new 30-inch diameter stormwater pipe that extends to the Birch Bay-Lynden Road intersection and catch basins on Harborview Road and Birch Bay Drive. The project will add approximately 2,000 feet of storm pipe and 22 catch basins.

These upgraded drainage systems will eliminate backwater flooding of nearshore drainage systems during high tide and reduce tidal and stormwater flooding on Birch Bay Drive and properties along it, according to the website.
