Pomona Mills Washout Bank Stabilization Project – Completed

Toronto and Region Conservation Authority (TRCA) had undertaken remedial bank stabilization works to protect York Region’s sanitary infrastructure along Pomona Creek, a tributary of the East Don River, in the City of Markham. The main objective of the works was to remediate the failed bank in order to provide underground sanitary infrastructure protection and reduce public safety risks.

Project Location

The project area was located along a stretch of Pomona Creek, a tributary of the East Don River, northwest of the closet major intersection at John Street and Bayview Avenue. The immediate bank failure was located northeast of the Pomona Valley Tennis Club parking lot, which is found within Pomona Mills Park at 200 John Street, Markham.
