E. Oregon Street Phosphorus Management Retrofit

​Project Overview: EV-0139

Lake Whatcom, the drinking water source for over 100,000 residents of Bellingham and Whatcom County, has experienced a decline in water quality. Residential development is one of the causes of excess phosphorus (natural and man-made nutrients that harm lake quality) in the lake.

The City is part of a multi-jurisdictional effort to reclaim a healthy watershed by implementing projects and programs aimed at eliminating phosphorus loading in stormwater. These efforts include aggressive retrofitting of existing stormwater infrastructure to maximize pollution-removal opportunities.

This project addresses a portion of the watershed that currently drains to Lake Whatcom without phosphorus treatment.  It involves installing treatment and infiltration systems on an undeveloped City-owned parcel. The systems are designed specifically to reduce phosphorus in runoff from over 20 acres of residential development and public rights-of-way.

Construction will include the installation of a vault using a crane, which is expected to impact traffic.

Landscaping on the City lot, which is next to Silver Beach Creek, will be upgraded to act as a natural filter for runoff. In addition to this natural filtration, leading edge technology will be used to capture and treat pollution in runoff. The existing pipe and ditch system will be upgraded to better control drainage along Haggin Street and E. Oregon Street. Newly landscaped areas will provide a more protective buffer for the creek, reducing high flows that could otherwise result in erosion of the creek channel, and helping to improve the creek's water quality.
