About the Project

Sparrow Pond was originally constructed in 2001-02. Over time, the pond has filled in with sediment. The restoration was identified as part of the 2012-13 Watershed Retrofit Study, and funding was allocated for design through the Capital Improvement Program in 2018.

The project goal is to restore the pond to the original depth by removing sediment, add a sediment collection forebay to allow easier maintenance and sediment removal, maximize water quality benefits, and restore habitat.
