E. Oregon Street Phosphorus Management Retrofit

Project Overview

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.

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.
