The outfall of the Duncan Woods Creek sewer.

Duncan Woods Creek Storm Sewer

c. 1970 concrete storm sewer drains Hillcrest, Seneca Heights, Highway 404

This decently-sized storm sewer was built in the late 1960s or early 1970s to bury the upstream elements of Duncan Woods Creek, a tributary of the German Mills Creek and ultimately the east branch of the Don River. Construction of this drain provided a conveniently located storm trunk sewer for new subdivisions, Seneca College and Fairview Mall, which were all being built atop the creek's watershed, and removed a ravine in a time when open waterways were still viewed primarily as a nuisance in suburban paradises of the sort that North York aspired to be.
