As a result of the damages caused by the extreme weather events, the project identified repairs and resiliency enhancements to shoreline erosion control infrastructure as being the primary action of this project. These repairs stretch from Marie Curtis Park in the west to Bluffer’s Park in the east and includes 11 TRCA erosion control assets within Ashbridges Bay Park, Bluffer’s Park and Humber Bay Park East and West. The City’s proposal also recognized that healthy trees provide an essential stormwater management service that can proactively mitigate the risk of floods. By expanding the City’s newly planted tree program and increasing tree maintenance and natural area restoration, the proposed projects aims to increase the number of healthy trees that provide this service. Native plantings along the shoreline will also provide erosion control, proactively addressing erosion post floods.
In 2019, the City of Toronto submitted the Tree Canopy and Waterfront Shoreline Project, in collaboration with the Toronto and Region Conservation Authority (TRCA), to the Disaster Mitigation Adaptation Fund, to support the city’s efforts to adapt to increasing and intensifying weather events and reduce the impacts of natural disasters such as flooding. This was done in response to significant erosion and damage that had occurred to the shoreline during the 2017 high lake level event and April 14-15, ice storm event. The federal government contributed $11.9 million through the fund and the City of Toronto another $17.9 million to cover the costs of the project which include; repairs and enhancements to shoreline erosion control infrastructure, remedial flood protection, path/boardwalk repairs, and an expansion of the City’s newly planted tree program to increase tree maintenance and natural area restoration. The City’s proposal recognizes that healthy trees provide an essential stormwater management service that can proactively mitigate the risk of floods by reducing peak flows. The project will reduce the number of residents without essential services and it is expected to save over $6 for every $1 invested in long-term savings on recovery and replacement costs. It is also projected to ensure the resilience of 19,335 people across an area of 9 km2 exposed to flooding.
