The City of Markham has completed a Class Environmental Assessment (EA) of the Glynnwood Tributary area storm sewer system. The recommended solution is to improve the storm sewer system capacity to convey runoff in the Bayview Avenue area from larger storm events to the Glynnwood Pond.
The study was initiated to address flooding issues that have occurred during intense rainfall events in the vicinity of Thornhill Community Centre on Bayview Avenue between John Street and Green Lane. The study also encompasses the existing Glynnwood Pond, located near the northwest corner of John Street and Bayview Avenue, which acts as a local drainage destination for storm runoff.
