These Cohort 2 project further refined the municipal natural asset methodology that was piloted in Cohort 1, and added additional practical examples to the evidence base for municipal natural asset management.

The Oshawa Creek south of Oshawa’s downtown core is experiencing erosion from more frequent storm events. This project explored how to increase the quality and resilience of the riparian area and stream banks along the Oshawa Creek.

Project findings show that natural assets along this segment of the Creek currently provide a stormwater management value of $18.9 million. When including the full Oshawa Creek watershed including the surrounding floodplain, this increases to between $392 million and $414 million. Replacing the natural assets with an engineered asset would reduce the ability to retain water, leading to the potential for more flooding.
