About this project

The City of London and Matrix Solutions (Ecosystems Recovery Inc.) are starting the detailed design and tender preparation of various identified works in the Hyde Park EA Addendum (AECOM, 2020). Project location and project work details are listed below.

Since the completion of the 2002 Class EA, the area and regulatory environment has evolved which caused the City to restudy and publish an EA Addendum in 2018. This evolution included changes to development plans and patterns, increased prominence and emphasis on Low Impact Development, increased emphasis on permanent private systems as well as climate change considerations.

This assignment looks to implement several key projects identified in the EA Addendum. Specifically, this assignment will involve the detailed design and tender preparation of the following projects:

  • Retrofit Outlet Structure for Hyde Park SWMF 3E.
  • Retrofit Hyde Park SWMF #4 with habitat enhancements.
  • Investigations of Existing Cantebury Estates SWM Facility.
  • 70 +/- metres of Stanton Drain natural channel Remediation (110 +/- metres following the centerline of the channel); and
  • Incorporate and/or verify natural channel design, ecological enhancements and applicable mitigation/compensation features for projects listed above as identified in the Environmental Impact Study (EIS) completed during the EA and any additional features identified through this detailed design.

    The outlet structure for SWMF 3E is to be retrofitted to optimize the quantity and erosion control volume of the existing facility. The retrofit will also improve erosion and flooding conditions downstream.

    SWMF 4 is to be retrofitted to provide water quantity, quality and erosion control to all upstream lands. The proposed retrofit includes expansion of the facility to the west, to include a connection to the existing channel. The design will include habitat enhancements components through the inclusion of shallow wet pools.

    The existing pond feature located west of the Stanton Drain and South of Gainsborough Road will require further detailed ecological investigations and assessments specific to the recommended works. The consultant will include a surface water assessment of the noted feature in addition to the wildlife protection and any other ecological work prior to final design and construction.

    Remediation of and design of 70 +/- metres of the southern portion of the Stanton Drain. These works were originally identified in the 2002 EA with the majority of the upstream portions of drain having been remediated in 2013. The remaining length is to be completed in order to finish the channel re-profile. Natural channel design elements will be used to maintain the meanders, increase ecological benefits and function.
