Toronto and Region Conservation Authority (TRCA) conducted remedial bank stabilization works for sanitary infrastructure protection along Pomona Creek, in the City of Markham. The main objective of the works included stabilization of the failed bank for underground sanitary infrastructure protection and to reduce overall public safety risks.

The project area was located along a stretch of Pomona Creek, a tributary of the East Don River. The work area was located within Royal Orchard Park, located northeast of the intersection of Yonge Street and Royal Orchard Boulevard, in the City of Markham.

Scope of Work
- Start Date: January 2019
- End Date: June 2019
The Pomona Creek Sanitary Infrastructure Protection Project Site: P-080 was considered high priority because bank erosion posed a risk to regional sanitary infrastructure and overall public safety. The scope of work included the following:
