Stormwater design forthcoming

By Meg Olson

After spending the winter analyzing stormwater shortcomings along Semiahmoo Parkway and Drayton Harbor Road, the city of Blaine is starting to design a solution.

“If you drive through or live in that area you know there are issues with water overtopping the road in heavy rainfall,” Blaine public works director Steve Banham told city council members at their March 27 meeting.

Engineers will start by making improvements to the Drayton Harbor outfall near the existing sewage treatment plant and work uphill. The first phase of the project will be to replace the ditch between Mallard Loop and the outfall with properly sized piping, which will keep water from running into the Aerie during winter storms. Banham said by replacing the open ditch with covered piping they created the opportunity to use a $100,000 grant from the state transportation improvement board for a separate pedestrian walkway, “which is sorely needed in that area.”

Banham said he hoped to have this phase of stormwater improvements in place before next winter and that engineers would move on to design fixes for other trouble spots. “If you make improvements from the wrong end you make it worse where it discharges,” he said. A pipe under Drayton Harbor Road to prevent overtopping is planned. Banham said they were also meeting with the Semiahmoo Homeowners Association on some joint solutions. “One of the problems is in one of their detention ponds,” he said.

Council unanimously approved up to $23,000 of design funds for the project.
