Clair Creek restoration at Keats Way to McDougall Road

In 2020 the City of Waterloo completed the Stormwater Management (SWM) Master Plan. As part of this process, the portion of Clair Creek between Keats Way and McDougall Road was identified as a priority area for erosion control and creek bank stabilization. We want to reduce the risk of erosion, flooding, and damage to private property in this area.

In addition to the need to replace failing gabion walls (the metal baskets filled with rocks) supporting the creek bank, the SWM Master Plan also identified that the preferred alternative may include the need for a new storm sewer (by-pass) along Keats Way to accept peak water flows and reduce further erosion in the creek course.

Since this portion of Clair Creek runs within private property, access will be needed through those properties in order to perform the necessary creek stabilization work. We understand that although the creek bank stabilization work is necessary, the construction portion will be an inconvenience and source of disturbance for a time for property owners in the area. Our goal is to work with property owners to understand all the potential impacts as we design improvements to benefit the neighbourhood.

As a first step, In order to help us fully understand the current and historic conditions along the creek corridor, we are asking property owners to please complete the project questionnaire. The answers will help the project team identify and consider all the challenges and opportunities we will face when determining the best solution for the erosion and flooding that this area experiences. The questionnaire is the same as the one being mailed to houses, and only one copy of your responses is required. Please complete the questionnaire by October 1, 2021.

    The background work for this project was part of the city's Stormwater Management (SWM) Master Plan study. Public consultation for the study happened throughout 2017 and 2018, and the plan was completed in 2020. The plan is a very large document, and has been split into several sections on the city's website to help make it more accessible.

    The part of the SWM Master Plan that relates to this project can be found on page 215:

    12.4.2.7 Clair Creek Tributary 1, Site CLR-T1-E1 The preferred alternative at this site is full channel restoration. The existing gabion baskets will be removed and replaced with armourstone walls.

    Gabion baskets are the metal baskets filled with rocks, and they are more prone to shifting and movement than armourstone, which are large, solid rectangular chunks of rock.

    While this replacement will help prevent the further risk of erosion and help to protect the creek bank and nearby properties, another concern with this section of Clair Creek is flooding. In the full erosion report included as Appendix L for the study, the portion related to this project also notes:


    City to consider additional hydraulic study at erosion site CLR-T1-E1 to investigate flow diversion options through storm sewer for alleviating future flood and erosion risks.

    As part of the work on Clair Creek at Keats Way, the project team will evaluate the option for putting in a storm sewer bypass along Keats Way to help manage peak waterflow in the creek, and reduce the risk of flooding. This will be evaluated during the design stage of the project.
