Toronto and Region Conservation Authority (TRCA) activities in flood risk management extend beyond capital works and land-use planning, and include emergency management planning with partner municipalities, flood forecasting and warning, and education and outreach.
In addition to background study reports, the actions taken by TRCA to support remediation of riverine flood risks in the Rockcliffe area include:
- Identifying the Rockcliffe area as a priority area for risk communications and flood education programs
- A dedicated real-time monitoring water level gauge was installed at Black Creek, downstream of Alliance Avenue in 2016, and a real time precipitation gauge was also installed in the catchment, which assists in flood forecasting and warning, as well as emergency preparedness.
- Development of an updated two-dimensional hydraulic model (2D model), which provides enhanced riverine flood risk information (i.e., flood depth, velocity, risk to life parameters) and will be utilized as a basis for feasibility/conceptual design studies
- Continued investments for the operation and maintenance of flood infrastructure within the Black Creek watershed, namely:
- Black Creek Dam Safety Review (2017)
- Black Creek Reservoir Dredging and Maintenance Project (2017)
- Black Creek Channel Restoration (2013-2016)
- Black Creek Channel Guardrail Installation (2016)
