PROJECT: Chapman Valley (Humber Creek) – Phase 1
CLIENT: City of Toronto
DESCRIPTION OF PROJECT:
- A sanitary sewer siphon within Humber Creek became exposed due to the severe degradation of soft shales in the watercourse.
- Water’s Edge worked with the City of Toronto to assess and design a robust channel that will protect the sanitary siphon as well as a stormwater outfall and the newly constructed downstream road crossing.
- An armourstone channel with purposefully designed step pool features was the preferred solution for the long-term protection of the channel. The banks of the channel were also lined with boulder buttressing and shrub plantings.
- A significant quantity of shale material was removed and disposed of and the bed of the creek was brought up to the design elevation.
- Water’s Edge provided all tendering and design services prior to construction.
- Water’s Edge provided full time contract administration during the construction phase.
- A monitoring plan was setup over several years to evaluate the long-term stability of the new channel.
- Phase 1 construction was completed in Summer 2021.
