6 6 Green Strip Current consultation Public consultation from March 26 to April 9, 2018 Suggested design and survey available online:

7 7 Noise Level Analysis Montréal-Ouest

8 8 Aerial view initial situation

9 9 Aerial view current situation

10 10 Configuration prior to the project Brock/Sainte-Anne-de-Bellevue area

11 11 Configuration after the project Brock/Sainte-Anne-de-Bellevue area

12 12 Noise surveys conducted Montréal-Ouest: December 2008: Noise survey Road component (study area of 300 metres from autoroute 20) November 2011: Cumulative noise impact Road and rail components (study area of 300 metres from autoroute 20) 2017: Noise survey Rail component (study area at more than 300 metres from autoroute 20)

13 13 Some information: Noise indicator Noise level A-weighted L eq,24h (dba) (L = Level and eq = equivalent) Indicator that cumulates all noise variations over a 24-hour period Why use an indicator: Mathematical expression used to represent a complex situation that varies in time and space Makes it possible to measure and compare the sound environment at different geographical points, at different times of the day or year Represents the impact of noise on a person s health and discomfort

14 14 Noise scale 3 dba barely perceptible variation 5 dba perceptible variation 10 dba double or halves noise level 55 dba et - Recognized as an acceptable level Noise levels do not ad up in a linear manner 2x noise sources 2x noise levels

15 15 November 2011: cumulative noise impact Road and rail components Before the project Study area of 300 metres 35, prom. Ronald Road 45 Train 52 Total , av. Brock Sud Road 62 Train 62 Total 65 Current noise barrier 86-88, prom. Ronald Road 62 Train 72 Total 72 16, prom. Ronald Road 63 Train 73 Total 73 CENTRE-VILLE

16 16 November 2011: cumulative noise impact Road and rail components After the project Study area of 300 metres 35, prom. Ronald Road 44 Train 54 Total , av. Brock Sud Road 61 Train 65 Total Current noise barrier 86-88, prom. Ronald Road 57 Train 72 Total 72 0 Planned noise barriers 16, prom. Ronald Road 62 Train 73 Total 74 0 CENTRE-VILLE

17 : Noise impacts rail component (study area at more than 300 metres from autoroute 20) Noise readings 113, av. Brock Sud 3 h (10 a.m. to 1 p.m.) Trains 46 Total , av. Ballantyne S. 3 h (4 p.m. to 7 p.m.) Trains 45 Total , av. Brock Sud 15 h (7 a.m. to 10 p.m.) 9 h (11 p.m. to 7 a.m) Trains 45 Trains 36 Total 55 Total , av. Ballantyne S. 3 h (8 p.m. to 11 p.m.) Trains 46 Total h Trains 43 Total 53 CENTRE-VILLE Current noise barrier

18 18 Daily noise variation Noise readings in front of 130 Brock Sud Noise levels recorded between 9 a.m. and 3 p.m. (October 25-26, 2017) Daytime (9 a.m. to 3 p.m.) Sources: Passing trains Local and freeway traffic Work Neighbourhood Industrial sources dba

19 19 Daily noise variation Noise readings in front of 130 Brock Sud Noise levels recorded between 9 p.m. and 3 a.m. (October 25-26, 2017) Evening and nighttime (9 p.m. to 3 a.m.) Sources: Passing trains Local and freeway traffic Work Neighbourhood Industrial sources dba

20 : Noise impacts (study area at more than 300 metres from autoroute 20) Observations during noise readings (October 25-26, 2017) Area delimited by Brock, Carnavon, Ballantyne and Avon: Noise from trains passing on CN railways is not the main source of noise Passenger trains are barely or not audible Freight trains are audible but noise is similar to ambient noise Night: freight trains are more easily audible at night since noise levels from roads are reduced

21 : Noise impacts Rail component (study area at more than 300 metres from autoroute 20) Before the project 123, av. Ballantyne S. 47 dba 113, av. Brock Sud 47 dba 130, av. Brock Sud 47 dba 151, av. Brock Sud 47 dba 145, av. Ballantyne S. 48 dba CENTRE-VILLE Current noise barrier

22 : Noise impacts Rail component (study area at more than 300 metres from autoroute 20) After the project 0 123, av. Ballantyne S. 47 dba 113, av. Brock Sud 0 47 dba 130, av. Brock Sud 48 dba , av. Brock Sud 49 dba , av. Ballantyne S. 49 dba +1 Current noise barrier Planned noise barriers

23 23 Mitigation measures After the project Plantation of trees and shrubs Addition of an absorptive material currently being analyzed Current noise barrier Planned noise barriers

24 24 Noise follow-up: after completion of work Noise follow-up required by government Decree No (condition No. 15) Must be conducted 1, 5 and 10 years after completion of work (2021, 2026 and 2030) Objectives: Ensure that noise levels from the infrastructure of the Turcot project have not increased since before the project Assess the effectiveness of mitigation measures (noise barriers) If noise levels are too high: Adjustment of measures in place or implementation of new mitigation measures
