Notice of Study Commencement - Rowe Channel Upgrade Study Municipal Class Environmental Assessment


The Town of Whitby, in partnership with Central Lake Ontario Conservation Authority (CLOCA) has initiated a Municipal Class Environmental Assessment (Class EA) study to assess possible improvement alternatives for upgrading Rowe Channel, located between the Whitby GO Station and the Front Street Culvert outfall into Lake Ontario. The existing channel requires work to address the failing gabion baskets that line the channel. The study will assess the potential for reducing flooding risk to properties along the channel, minimize maintenance costs, identify opportunities to make improvements to the channel aesthetics, and reduce the presence of invasive species. The study will develop and evaluate a range of design alternatives and recommend a preferred solution for the upgrade. For more details and contact information, please click here.
