This erosion control project (cost: approximately $2 million) is the second attempt at preventing the stream from undercutting the ravine slopes below Summerhill Gardens. An earlier under-engineered attempt at a lower-cost solution in 2019-20 was swept away by summer storms the following July.
The engineering of the 2025 project is in part the result of a major hydrogeomorphic analysis of the Yellow Creek route through the Vale of Avoca that was commissioned by Toronto Water, for whom the creek serves as a major element of its stormwater drainage system. The geomorphic study (made public this year) will serve as a major analytic underpinning of the Master Plan to be developed for the ravine.
The project is due to be completed in mid-May 2025.
