The City of Markham is replacing existing storm sewers on Doncrest Drive, Poinsetta Drive and Daffodil Avenue as the first phase of the West Thornhill flood remediation project and the long-term City-wide Flood Control Program. These roads will be temporarily closed to through traffic during construction (local access only). Watermain replacement and road reconstruction will be completed on these streets and watermains will be replaced on Rossea, Spirea and Sunflower Courts.

The construction is scheduled to begin July 2014 and is expected to last approximately one (1) year. Doncrest Drive will be closed between Bayview Avenue and Prescott Court for approximately six (6) weeks beginning August 2014.
