West Don River Sewer Erosion Protection

Natural Channel Design to concurrently restore channel morphology and protect infrastructure

Toronto and Region Conservation Authority (TRCA), in partnership with the Regional Municipality of York, is proposing to construct erosion control works to protect a sanitary sewer exposed along the West Don River in the City of Vaughan, Ontario.

Palmer Environmental Consulting Group Inc. (PECG) was retained by Greck and Associates Limited to provide fluvial geomorphological criteria on which to design erosion protection works. PECG documented past morphological changes based on historical aerial photography and recommended changes to local channel morphology that address erosion risks while maintaining aquatic habitat values.
