Lakeside Lane Phosphorus Filter Upgrade

Project Overview

The Flynn Street Water Quality improvement project aimed to transform Flynn Street between Electric Avenue and Lakeside Lane to provide stormwater treatment for Flynn Street near Lake Whatcom. The work on Flynn Street represents the continued effort to provide treatment on all roads within the City Limits in the Lake Whatcom Watershed. The Flynn Street project included extensive planting to allow the native vegetation to capture and hold phosphorus. Roadway runoff will be better managed through additional piping and drainage structures as well as the addition of a stormwater treatment facility. The new media in the facility, including phosphorus-removing filter cartridges, has been given conditional approval from the Department of Ecology as a phosphorus-limiting best management practice (BMP).
