Press release - March 16, 2017

Costs of slope stabilizing work in the Vallée-Chaline residential sector
Saint-Lazare will cover the remaining cost using the accumulated surplus  

Saint-Lazare (Québec), Wednesday, March 15, 2017 – Following the adoption of resolution number 02-098-17, on February 21st, 2017, authorizing the City of Saint-Lazare to conclude an agreement with the Ministry of Public Security ministry in order to finance 74 % of the work required to stabilize certain slopes of the banks along the Quinchien River and one of its tributaries in the Vallée-Chaline sector, Council is happy to announce they will finance the remaining 26% of the cost straight from the non allocated operating surplus, better known as the " accumulated surplus ".

“The residents of Vallée-Chaline have been through a great deal over the last few years with respect to this issue, claims the councillor of this district, Ms. Brigitte Asselin. They have experienced more than their fair share of worry. I am happy that the council has agreed that residents’ not need to worry about the financial concerns as well”, added Ms. Asselin.

It must be noted that the cost to realize this work is presently estimated at $8,000,000. The Quebec government will take care of $5,920,000 and the City, $2,080,000. The work aims at stabilizing 1.5 km of bank along the Quinchien river.

“Members of council came to this conclusion considering that the work will eliminate potentially aggravating factors in this sector, noted Mayor Robert Grimaudo , but also continuously ensure the safety of individuals, as well as private and public property, including existing public infrastructures such as roads, the water network and other public services (electricity, telecommunications, etc.). The Quinchien river is an important infrastructure that services residents of the town, and a great part of the work will be done on land that belongs to the town, added Mayor Robert Grimaudo. The Town therefore has great interest in covering the remaining costs,” he concluded. 

An invitation to the information session on Tuesday, March 28, 2017 was mailed out on Monday, March 13 to property owners in the Vallée-Chaline sector. Residents are invited to register online or by phone. Proof of residence will be required to attend the meeting. 

The Town plans on meeting the media. An invitation should follow shortly.

Landlocked of Vallée-Chaline sector

Since the opening of Rue de Carillon in November 2014, Vallée-Chaline sector is not landlocked by a railroad track at the level of Chemin Saint-Louis anymore. The temporary emergency exit at the end of Rue Chaline is now closed.The road signs guiding Vallée Chaline residents towards the emergency exit will be removed soon.

Historic of the creation of a 2nd permanent exit

This road was built in two (2) phases and enabled the Town not only to put a stop to the train whistle sounded at the unprotected level crossing on Chemin Duhamel at the Chemin Sainte-Angélique intersection (phase 1) but also to remedy the “landlocked” problem caused by the railroad track (phase 2). The phase 2 involved expropriation, the purchase of land, the transfer of a private road and the construction of a new street.

Piezometers installation

On September 22, 2014, Ministère des Transports (or a mandated firm) has proceed to the installation of piezometers in Vallée-Chaline sector for ongoing analysis.

Land-slide prone areas

In Saint-Lazare, there are four main landslide-prone areas: a residential sector along the Quinchien River (parts of Vallée Chaline and Sainte-Angélique, Duhamel and Legault roads and Route de la Cité-des-jeunes) and three agricultural sectors (small portions of Chemin du Fief and Chemin Saint-Louis). In total, slightly more than one hundred properties are concerned.

What is a landslide?

It is the downward movement under the force of gravity of a mass of soil, sweeping all or part of a slope (sloping piece of land) along with it. A landslide can occur when the stability conditions of a slope are modified naturally (erosion) or artificially (excavating, backfilling). Most landslides occur where there is a slope, usually along the clay banks of waterways. In 40% of cases, they are triggered by human activity, which is why it is important to consult the Environment Department, avoid any inappropriate human activity, look for warning signs and report them to the Town.
