West Thornhill – Phase 3C: Storm Sewer and Watermain Replacement
Project Description
The City of Markham will be upgrading storm sewers, watermains and sanitary sewers within the West Thornhill area as part of the City’s flood control program, as shown in the attached map.
The study area is located along Glen Cameron Road from Yonge Street to Henderson Ave, Clark Avenue from just west of Willowdale Road and just west of Henderson Avenue, Pheasant Valley Court and Mira Road and Lillian Avenue.
Project Activities
- New storm sewer and watermain along Glen Cameron Rd., Lillian Ave., Pheasant Valley Crt., and Mira Rd
- New storm sewer on Clark Ave
- Resurfacing of roads where sewers or watermains are replaced
Schedule:
- The construction is scheduled to begin May 2022 and is expected to be complete in October 2023.
- Roads will remain open to local traffic
- Residents will be able to access their driveways at all times although there may be delays during working hours
- Access for emergency vehicles will be maintained
- Provisions will be made for collection of solid waste and recycling materials
- Henderson Avenue and Proctor Ave intersection will be closed to traffic for from the week of July 4 2022 to July 15 2022. No traffic will be allowed at the intersection during this time to facilitate storm sewer installation. North – South bound traffic on Henderson Ave will be opened after 2 weeks. East –West bound traffic on Proctor Ave/Glen Cameron Road will be opened after another 2 weeks.
- Some temporary disruption to driveway access should be expected during working hours, in the active construction area
- Roadway will be restored at the end of each working day to restore driveway access
- Street parking restrictions will be waived to allow temporary street parking if required (e.g., during construction of new concrete curbs)
- York Region has an EMT station located along Glen Cameron Road
- The City of Markham has coordinated with York Region to construct along Glen Cameron road in stages to minimize disturbance to ambulance traffic. One lane will remain open at all times. Both driveways at the EMT station will be accessible to Region staff except while construction of the storm sewer is directly in front of a driveway. At least one driveway will remain open at all times.
- Clear communication between York Region and the City will be established to facilitate coordination of construction works
- City of Markham and RVA have coordinated with York Region to reduce incoming traffic to Glen Cameron from Yonge Street during construction via a temporary left turning lane closure.
- Water shut-offs may be required during construction to transfer water supply to relocated watermains
- Shut-offs will typically be 3-4 hours in duration
- Affected residents will be given 48 hours notice
Construction notices to residents in the immediate area of the construction have been distributed.
