Sediment Removal at Ponds 50 and 71

Project Description

The City of Markham will be removing sediment and performing maintenance at two stormwater management ponds, Pond #50 located near the intersection of Leslie and John Street just west of Rockingham Court and Pond #71 located in the northeast quadrant of Berczy Village, south east of Castlemore Road and Stonebridge Drive.

The City of Markham undertakes periodic inspections of its stormwater management facilities, including Ponds 50 and 71, as part of its stormwater management maintenance program. This includes visual inspections and reports, as well as periodic bathymetric (i.e., sediment level) surveys. Through this process, the need to remove accumulated sediment in Ponds 50 and 71 had been identified to ensure efficient operation.

Project Activities

• Flushing and cleanout of pond infrastructure (e.g., sewer pipes) ;
  
• Sediment removal from ponds and disposal off-site;
• Planting vegetation and seeding; and
• Clean-up and restoration of the site after completion of the work.

While there will be some inconvenience to the residents who live around the construction site and general public who work near the area, the Contractor and the City staff will work together to complete the project as quickly as possible.  All areas disturbed during construction will be restored to their original conditions.

Schedule

The construction is scheduled to begin at the beginning of June 2024 and is expected to be completed by the end of September 2024, weather permitting.  During the construction, roadways will be open at the above noted locations.
