The next phase of drainage improvements for the Grand Marais Drain is well underway to the section between Dougall Avenue and South Cameron Boulevard.

“The weir, which is a water control structure, is presently in failure in this area,” explains John Henderson, Water Resources Engineer for the Essex Region Conservation Authority. “Rather than replacing it with another steel structure, a more permanent solution of three rock steps is being constructed in the drain bottom to improve drain stability and flow.”

As part of the project, all of the overgrown trees and brush have been removed from the banks. “A biological assessment was first undertaken to confirm that no significant species were found in this area,” Henderson went on to say.

A planting strategy to re-grow grasses and select trees that will not impact flow within the channel or obstruct future City drain maintenance is included in the overall plan.

This project is funded 50% by the City of Windsor and 50% through funds acquired by ERCA from the Ministry of Natural Resources’ Water and Erosion Control Infrastructure fund.
