EXECUTIVE SUMMARY The City of London, Ontario has retained the IBI Group (IBI) in collaboration with WSP Canada Inc. (WSP) to provide engineering consulting and environmental assessment services for the development of a 24km-long Bus Rapid Transit (BRT) system for London, Ontario. As a part of the environmental assessment services, this noise and vibration study assesses the potential noise and vibration impacts of the BRT system on the surrounding area. The scope of this study addresses the potential noise and vibration impact of construction, road widening, and operation of the BRT system. The road traffic volumes were projected based on Turning Movement Counts (TMC) and future growth rates provided by the project team. Road noise levels were calculated using both the method outlined in the Ontario Ministry of the Enviroment document ORNAMENT (October, 1989) and the MOECC STAMSON 5.04 Computer Program for Road and Rail Traffic Noise Assessment. The projected increase in noise levels as a result of the implementation of the London BRT system is estimated to be greater than 5 db at four receptor locations. New 1.8 m to 2.4 m high sound barriers are recommended to attenuate the increase in sound levels. This study concluded that the existing noise sensitive land uses will not be impacted by the construction, road widening, and operation of the BRT system provided that all recommendations in this report are implemented.

1 INTRODUCTION The City of London, Ontario has retained the IBI Group (IBI) in collaboration with WSP Canada Inc. (WSP) to provide engineering consulting and environmental assessment services for the development of a 24km-long Bus Rapid Transit (BRT) system for London, Ontario. The BRT system is comprised of four segments, combined into two operational routes: the north and east corridor, and the south and west corridor, as presented in Figure A below. The BRT network was approved by the City of London Council with the Rapid Transit Master Plan in July 2017, and is comprised predominantly of dedicated bus lanes on existing streets, either in the curb or median lanes. The BRT corridors will also incorporate enhanced pedestrian amenities and active transportation infrastructure where feasible. A total of 35 new, fully-accessible BRT stops are provided at key signalized intersections throughout the network, with enhanced passenger amenities and safety features. The project will require the purchase of an additional 28 vehicles to operate the BRT services, which will be phased-in gradually as the BRT corridors come online. As a part of the environmental assessment services, this noise and vibration study assesses the potential noise and vibration impacts of the BRT system on the surrounding area. The scope of this study addresses the potential noise and vibration impact of construction, road widening, and operation of the BRT system.

2 STUDY AREA AND SURROUNDING LAND USES For the purposes of this evaluation, the study area extends 600 metres on both sides of the proposed 24 kilometre BRT system and adjacent residential areas. In practical terms, the study area extends only as far as the first row of housing since there will not be impacts beyond the first row. Existing land uses vary along the study corridors with a mix of recreational, residential, commercial, and institutional uses. Downtown London is primarily commercial and institutional uses while a couple of kilometres away from the downtown core is primarily residential. Notable land uses along the BRT corridors include Western University, Masonville Place, Cherry Hill Mall, North American Trade Schools, Gateway Casinos, and Fanshawe College. For more information about the surrounding land use, the City of London s website contains an interactive map at http://maps.london.ca/citymap/index.html?viewer=zoning. The noise and vibration assessments were undertaken based on a selection of private residential homes adjacent to the BRT corridors to represent the locations where the potential worst-case impacts to noise and vibration sensitive areas are expected.

3 NOISE GUIDELINES When examining the noise impacts of transportation improvements on existing residential areas, the Ministry of the Environment and Climate Control s approach for the assessment of noise impacts is documented in "A Protocol for Dealing with Noise Concerns during Preparation, Review and Evaluation of Provincial Highway Environmental Assessments", February 1986, prepared by the Ontario Ministry of Transportation and the Ministry of the Environment (hereafter referred to as the Protocol). The Protocol states "The objective for outdoor sound levels is the higher of the L eq 55 dba or the ambient. The significance of a noise impact will be quantified by using this objective in addition to the change in noise level above the ambient. Where noise increases above the ambient do not exceed 5 dba, no mitigation is required". A summary of the guidelines to determine noise impact is as follows: If the L eq 16 hour daytime traffic sound levels in the outdoor living areas of the adjacent dwelling units are less than or equal to 55 dba and the impact is less than or equal to 5 dba (over ambient noise levels), noise mitigation measures will not be required. If the L eq 16 hour daytime traffic sound levels in the outdoor living areas of the adjacent dwelling units are greater than 55 dba and the impact is less than or equal to 5 dba (over ambient), attenuation measures will not normally be required. For both cases noted above, if the noise impact exceeds 5 dba (over ambient), noise control measures should be investigated within the right-of-way and if mitigation is warranted, attempts should be made to reduce the noise to objective sound levels or as much as possible, within the constraints of administrative, aesthetic, economic and technical feasibility.

4 NOISE ANALYSIS NOISE SOURCES The primary noise sources are vehicular traffic along the major roads (Dundas Street, King Street, Oxford Street East, Oxford Street West, Highbury Avenue North, Wharncliffe Road North, Wellington Road, Richmond Street and Western Road). The road traffic volumes were projected based on Turning Movement Counts (TMC) and future growth rates provided by the project team. A medium to heavy truck ratio was not provided and a ratio of 5:8 was assumed. The traffic data used is provided in Appendix A. The conservative case of diesel BRT fleet was assumed. ESTIMATION PROCEDURES Sound levels were calculated using the method outlined in the Ontario Ministry of the Environment document ORNAMENT, October 1989 and the Ontario Ministry of the Environment and Climate Change (MOECC) STAMSON, Computer Program for Road and Rail Traffic Noise Assessment (Version 5.04 issued in 2000). SETBACKS, ELEVATIONS, AND RECEPTOR HEIGHTS An Outdoor Living Area (OLA) is an outdoor area easily accessible from a building and is designed for the quiet enjoyment of the outdoor environment. A review of the study area identified OLAs that would have the greatest exposure to the BRT corridor and therefore be most impacted by the project. The location of these OLA receptors are 3 metres from the rear façade of the building at a height of 1.5 metres above the existing grade at the critical noise sensitive areas. Table 4-1 summarizes all the assessed receptors. Table 4-1: Summary of Receptors NOISE RECEPTOR ADDRESS TYPE OF RESIDENTIAL UNIT N1 106 St Bees Crt. Detached House N2 38 St Bees Pl.

The largest change in sound levels is 9 dba. NOISE CONTROL MEASURES Based on the results summarized in Table 4-2, most receptors experience a small increase in sound levels but will not require noise control measures. However, receptors S1, S7, S9, and W3 increases by more than the 5 db. Noise control measures were investigated at these locations. It should be noted that increases greater than 5 db are predicted to only occurred as a result of intervening buildings needing to be removed to accommodate the design. Accordingly, it is recommended that sound barriers be constructed to provide sufficient attenuation to reduce sound levels to objective sound levels for the affected receptors. Table 4-3 summarizes the recommended noise control measures. Rapid Transit Corridors EA Noise and Vibration Study Project No. 141-25-01 City of London WSP April 2018 Page 7

5 CONSTRUCTION NOISE With respect to the noise impacts during construction of the London BRT, the following should be specified during the preparation of detailed design drawings and adhered to during construction: The Contractor will be required to comply with the City of London s noise by-law (Noise By-Law, PW-12) regarding noise emission standards for construction equipment that may be in place at the time of construction. General noise control measures (not sound level criteria) will be referred to, or placed into the City of London contract documents. Any initial complaint from the public will require verification by the City of London to determine if the general noise control measures agreed to, are in effect. The City of London will investigate any noise concerns, warn the Contractor of any problems and enforce its contract. Nighttime construction activities should be avoided to reduce the potential impact of construction noise. Construction should be planned to minimize the number of nights where noisy nighttime construction activities may be required. All construction equipment used should be in good repair and properly maintained to limit noise emissions. All construction equipment should be operated with effective muffling devices that are in good working order and idling of construction equipment kept to a minimum to reduce noise from construction activities. Unnecessary noise caused by faulty or non-operating components shall be addressed by regularly maintaining all equipment. Noise emissions from construction equipment are to be in compliance with the limits set out in NPC-115 and NPC-118. The concurrent use of high impact construction equipment such as pile driving should be avoided. The feasibility of augur pile driving should be investigated if pile driving is required. Construction noise mitigation options should be considered based on administrative, operational, economic, and technical feasibility.

6 VIBRATION ASSESSMENT Vibration impacts on nearby vibration sensitive areas due to the operation of the proposed BRT system is not expected to be a concern. The rubber tires and suspension systems of the buses and trucks will provide sufficient vibration dampening and isolation under satisfactory pavement conditions. There are no federal, provincial, or municipal construction vibration limits. The construction vibration is temporary and vibration-intensive activities such as pile driving are not expected to occur. However, construction best practices should be followed. Construction activities should be kept as far as possible from nearby structures and the duration of construction activities near structures should be kept to a minimum.

7 CONCLUSIONS AND RECOMMENDATIONS CONCLUSIONS The conclusions of the noise and vibration assessments are as follows: The projected increase in noise levels as a result of the implementation of the London BRT system is estimated to be greater than 5 dba at receptors S1, S7, S9, and W3 and warrants an investigation of mitigation measures. Vibration impacts on nearby vibration sensitive areas due to the operation of the proposed BRT system is not expected to be a concern. RECOMMENDATIONS Based on the review of proposed noise mitigation at the affected receptor locations, new 1.8 m to 2.4 m high sound barriers are recommended. The locations and heights of the sound barriers are schematically shown Appendix C, Figures C-1 to C-4. Construction noise control program noted in Section 5 of this report be adhered to during the construction of the London BRT system. Construction best practices should be followed to minimize the possibility of a potential noise/vibration impact.
