Welcome to the project page for the cleanout and retrofit of Trillium Valley Park Pond 48. Pond 48 was identified for cleanout given the level of sediment accumulation in the pond. Pond 48 was identified as a candidate for retrofit to improve performance and address operational issues. The retrofit of Pond 48 requires the completion of a Schedule B Environmental Assessment to identify and evaluate alternatives for retrofitting the pond and select a preferred alternative to be implemented.

This page will provide information as the project progresses from the Environmental Assessment stage, to the detailed design stage and finally to construction. Project updates will be posted in the newsfeed and the current progress of the project is noted in the project Lifecycle. The page may be open to public comments for limited time periods at key stages of the project, so please check back often or subscribe to follow the project to receive email updates.

    The 30-day public review period for the study ended on October 8, 2022. The documents remain available for viewing, but the official commenting period for the Project File Report is finished. The city and our engineering consultant will review any comments received and begin the detailed design and approvals process.


    The city is pleased to announce that it has completed a retrofit assessment of Trillium Valley Park Pond 48. The project has been completed in accordance with the Municipal Engineers Association Municipal Class Environmental Assessment document (October 2000, as amended in 2007 and 2011), which is an approved process under the Ontario Environmental Assessment Act. Pond 48 has been completed as a Schedule ‘B’ project, which involves a greater degree of study and public consultation, including the completed PIC to present the project to the public and seek input on the identified preferred solution.

    A Project File Report has been prepared, which documents; the planning and design process, how public, regulatory agency input was addressed, the evaluation and selection of the preferred solution, along with associated mitigation measures to address impacts, and next steps towards project implementation.

    The filing of this report completes the planning and conceptual design stage of the project. By way of this notice, the report is placed on record for a 30-day public review period starting on September 8, 2022 and ending on October 8, 2022.
