Vallée-Chaline: drone inspections to start this spring April through June 2017
Notice to residents
SAINT-LAZARE (Québec), on Tuesday, April 11th, 2017. - The City of Saint-Lazare wishes to inform Vallée-Chaline residents that drone inspections of the banks concerned by the stabilization work along the Quinchien River, will start this spring and will also take place in the fall, the more critical periods for landslides. These inspections will continue until the work is realized.
This spring, the drone operated by Drone Box, a firm appointed by the Public Security Ministry, will fly at 10-day intervals, when sun conditions are optimal, from mid to late April until early June. The first image capture is planned to be on Thursday April 20, 2017, starting 8:30 am. Shots where properties or people are recognizable will not be used. The drone flies as to not disrupt or disturb human activity and wildlife.
For all the information concerning this work, residents are invited to visit the website at http://www.ville.saint-lazare.qc.ca/en/zonesdecontraintes, to subscribe to the Vallée-Chaline online newsletter at http://www.ville.saint-lazare.qc.ca/en/infolettres and to the Community alert system at http://ville.saint-lazare.qc.ca/en/alertealacommunaute, where you can choose to receive important notices by landline, mobile phone, text, email or all of the above at once.
For any other question concerning these activities, Vallée-Chaline residents can contact the line which is dedicated to them at 514-250-0964.
Why a drone?
The surveillance is conducted mainly for the purpose of monitoring slopes along Quinchien River and one of its affluents with a view to modifying sectors that have suffered severe erosion, small rockslides at the base of the slope or landslides. This type of surveillance is standard in prevention projects.
The images captured will be analyzed by geotechnical engineers from the MTMDET who will monitor changes to the concerned watercourses. If a landslide is detected, the Municipality will be immediately notified so that they may inform residents who are directly affected.
It is essential that citizens inform the Town of Saint-Lazare if they witness any landslides or any early warning signs of landslides on their properties.
For more information on what constitutes an early warning sign of a landslide, please visit the Web site of the Ministère de la Sécurité publique.

Meeting for Vallée-Chaline property owners last March 28, 2017
Slope stabilization work along Quinchien River and one of its affluents
Press release -March 29, 2017
Saint-Lazare (Québec), Wednesday, March 29, 2017 – Over 120 property owners responded to the invitation launched for a meeting on March 28, 2017 to address the slope stabilization work to be done in the Vallée-Chaline sector. Divided into two parts, the evening aimed to, first, inform property owners of the extent of the work to be carried out and, second, specifically address several of the properties located along Quinchien River. A total of 42 properties are directly affected by the stabilization work, estimated to cost $8,000,000.
Slated to begin in the winter of 2018–2019, the work to be undertaken in the 21 meanders over a distance of 1.5 km will help stabilize the slope in order to prevent an initial landslide and eliminate the possibility of changes over time. The sector’s residents should expect work to last over 15 weeks and more than 7,000 truckloads to remove the infamous “sensitive clay” that is responsible for major landslides. In total, 77,000 m³ of this material will be removed from the sector and replaced in large part by rockfill. This technical solution, put forth by the engineers from the Ministère des Transports, de la Mobilité durable et de l’Électrification des transports (MTMDET), has been used elsewhere in Quebec to strengthen slopes. It takes into consideration the potential of river flooding for a 0-100 year period and increases protection against the assessed risk by 30%. The MTMDET’s engineers individually evaluated all of the sites over several months and took into consideration all of the available solutions. In the end, the solutions that were chosen are those deemed the most appropriate for the situation. The work to be done requires the temporary or permanent removal of accessory buildings, above-ground pools and septic systems on several lots as well as the reprofiling of land slopes between 0 and 14 metres (6 m on average). Once the work is completed, lots will be revegetated and reforested using native species.
During the evening, 30 of the 42 concerned property owners were in attendance for an update on the situation. The MTMDET provided each of them with a fact sheet about their properties, illustrating the impact of the stabilization work using an aerial image and a scale plan to show reprofiling angles. The property owners were also invited to book individual and personalized meetings with representatives from the Town, the Ministère de la sécurité publique and the MTMDET for this morning, Wednesday, March 29, 2017 or Tuesday, April 11 between 9:00 a.m. and 4:00 p.m. Affected properties are mainly located on Charbonneau, Chaline, Du Chêne and Du Calypso streets as well as on Place Cardin.
Property owners who were unable to attend can access the information on the Town’s Web site at http://www.ville.saint-lazare.qc.ca/zonesdecontraintes at the end of the week of March 27, 2017.
They are also invited to share their concerns and questions with representatives from the Town and those from the Ministère de la Sécurité publique. Affected property owners who were not present at the meeting will be contacted.

Recall that, at the Town’s request, the Vallée-Chaline sector had been included as part of a constraint area (landslide-prone area) following signs of erosion along Quinchien River. Over the last few years, numerous resources and stakeholders from various departments and levels of government have been involved in developing the solution presented on Tuesday, March 28, 2017. Note that 74% of the cost of the work estimated at $8,000,000 will be covered as part of the 2013-2020 Climate Change Action Plan (2013-2020 CCAP) made possible through the financial support of the Green Fund—representing an amount of $5,925,000—and the remaining $2,080,000 will be absorbed by the Town’s accumulated non-affected surplus.
Costs of slope stabilizing work in the Vallée-Chaline residential sector
Saint-Lazare will cover the remaining cost using the accumulated surplus
Press release - March 16, 2017
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.

Rue de Carillon : permanent exit
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.
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.
