Deux-Montagnes, September 27, 2019 – Since mid-August, when the Quebec government authorized resumption of work, the City of Deux-Montagnes has been removing the temporary dike. Work was also done to prepare the ground for construction of the permanent structure. The City has also recently obtained permission from government authorities to make adjustments to the original dike project.
The dike route initially approved and presented to shoreline residents runs from 9th Avenue to 13th Avenue and into the Rue Lakebreeze. This route remains unchanged. However, the dike will be raised to 25.71 m (the initial height was 25.42 m) and interlocked sheet piling will be added to prevent quicksand effects. These panels, forming steel curtains sunk into the ground, will provide more strength and much greater resistance to leakage.
In the wake of the major spring flood of 2019, as well as the events that occurred in Sainte-Marthe-sur-le-Lac, engineers responsible for Quebec government dikes and dams developed a series of recommendations, and the adjustments to the Deux-Montagnes dike are based on these.
As some readers may recall, work along the shoreline was suspended from mid-April to mid-August (with the exception of the temporary dike). Now that sheet piling installation phase has begun, the City is confident that the dike will be completed and operational by the end of this year, as planned. Some finishing touches for esthetic purposes will be completed later on.
Rehabilitation work on waterfront lands (staircase and wharf construction, tree planting, etc.) is planned for next spring. Numerous meetings and discussions have already been held with the residents directly involved, and will continue in order to evaluate and address their individual needs and concerns.
Public access to the waterfront, in various forms, will also be planned and developed next spring, so that everyone can continue to enjoy our exceptional geographical location.
Tlls on residents’ private property along the dike route add to the complexity of the work. These structures will be inspected by City engineers, and some may need to be upgraded or reinforced. Nonetheless, the City of Deux-Montagnes reiterates the crucial importance of the permanent dike project and its construction on our territory. Together with our teams of engineers and specialists, we are conducting this major project with all due diligence, in compliance with current laws and regulations.
The City of Deux-Montagnes would like once again to thank residents for their patience, understanding, and cooperation.
