Committee Recommendations
The Public Works and Infrastructure Committee recommends that:
1. City Council request the City Manager with appropriate City staff to consult with the General Manager, Transportation Services, the General Manager, Toronto Water and the Toronto and Region Conservation Authority (TRCA) to consider the feasibility and conceptual design study for the recommended flood protection measures for the Jane Street crossing, as a project for intergovernmental funding and to provide a submission to the federal National Disaster Mitigation Program, and report back through the 2019 Budget submission.
Origin
Summary
The Rockcliffe area is located in the regulatory floodplain of Black Creek and has experienced surface and basement flooding during severe storms due to riverine flooding and overloading of the City's sewer systems. In 2014, Toronto Water and Toronto and Region Conservation Authority (TRCA) completed separate Environmental Assessment (EA) studies that investigated options and recommended measures to reduce sewer system and riverine flooding in the Rockcliffe area, respectively.
This report has been prepared by Toronto Water, in consultation with TRCA, to report back to City Council on the implementation of recommended measures from Toronto Water's 2014 Basement Flooding Study Area 4 EA (BF Area 4 EA) to reduce sewer system flooding in the Rockcliffe area. This report discusses the challenges of reducing sewer system flooding in the Rockcliffe area due to the impact of Black Creek (riverine) flooding on the sewer system and concludes that implementation of the BF Area 4 EA recommended sewer system improvements will not be effective in reducing basement flooding unless the TRCA EA's recommended riverine flood reduction measures are implemented.
On March 23, 2018, the TRCA Board approved that TRCA undertake feasibility and conceptual design studies in 2019 as a next step for the preferred measures to reduce riverine flooding in the Rockcliffe area from their 2014 Black Creek (Rockcliffe Area) Riverine Flood Management Class Environmental Assessment (TRCA EA). As riverine flood protection measures are completed in the Rockcliffe Area, Toronto Water will reassess the scope and costs of the BF Area 4 EA recommended sewer system improvements. Sewer system improvements that proceed to implementation, in accordance with City Council direction for the Basement Flooding Protection Program, will be identified through Toronto Water's annual Capital Budget process.
