Spring Mill Estates Water Quality

Impacted Ward: 5

Design Consultant: Bax Engineering

Project Description

The existing detention basin within the Spring Mill Estates subdivision lies at the confluence of 2 upstream branches of Cole Creek. In recent years, sediment transported by the creeks has settled out in the detention basin, causing parts of the basin to fill in. The purpose of the project is to construct water quality basins upstream of the detention basin to allow sediment to settle there, where it can be removed on a regular basis, improving the water quality in the detention basin and in downstream Cole Creek.
