1.0 INTRODUCTION

Stantec was retained by Ashford and Yonge Developments Limited to conduct a noise impact study for a proposed residential development located at 681-685 Yonge Street in Barrie, Ontario. A site plan and site location is provided in Appendix A. The study assesses the future noise contribution from nearby road traffic (i.e., Yonge Street and Ashford Road) on the Development. This report is prepared in support of the site plan application required for the by the City’s Engineering Department.

The development is located on a plot of land with Yonge Street to the south, Ashford Drive to the east, and residential dwellings adjacent to the north and west. The development consists of 33 townhouse units which are 3 storeys high. The townhouses are separated into 6 blocks along 3 rows.


Objective Limits August 4, 2017


2.0 OBJECTIVE LIMITS

Noise is recognized as a pollutant in the Environmental Protection Act, as it can affect many human activities. Municipal and provincial noise control guidelines in Ontario require that noise concerns be considered in the planning of any new development, preferably at the earliest stages.

In land use planning, although elimination or control of the pollution source is usually a primary objective, there are general limits as to what is practical and technically possible. This is particularly applicable to noise impacts. The City, under transfer from the Ministry of the Environment and Climate Change (MOECC), has authority to assess noise impacts from road sources adjacent to new residential developments.

The City of Barrie noise by-law 2006-140 (City of Barrie 2012) outlines several technical MOECC publications that form part of this recommended noise control by-law. This by-law does not specifically provide quantitative limits for assessing noise for urban planning and therefore was not used.

Noise criteria for transportation sources is addressed and outlined in the MOECC publication NPC-300 Environmental Noise Guideline – Stationary and Transportation Sources – Approval and Planning” (MOECC 2013), and therefore was used to assess the impact due to noise. A summary of the sound level objectives contained NPC-300 are listed in Table 2-1 for road traffic.

The criteria in Table 2-1 is the maximum noise objectives (sound level limits) beyond which mitigation or control measures are recommended in accordance with NPC-300. These measures can take the form of ventilation requirements, architectural design, warning clauses, building component construction, or noise barriers. Sound from surface transportation sources (i.e., road) are to be assessed to consider ventilation and warning clause requirements.

As detailed in NPC-300, road traffic sound level limits are 55 dBA during the daytime in Outdoor Living Areas and 50 dBA during the nighttime at the plane of window of the applicable living space. These limits are used to assess the need to specify building components beyond the OBC minimum requirements to ensure that indoor sound levels will be met.

Notes: 1 Daytime transportation noise averaged over 16 hour daytime period (07:00 to 23:00). 2 Daytime transportation noise averaged over 8 hour nighttime period (23:00 to 07:00). 3 OLA sound levels are predicted at a height of 1.5 m. It is defined as the common outdoor area allocated for recreational uses (e.g. an apartment or balcony with a depth of greater than 4m). 4 Indoor criteria are applied in a living room or similar during the daytime period and in sleeping quarter/bedrooms during the nighttime.


Sources and Methods August 4, 2017


3.0 SOURCES AND METHODS

Yonge Street is a four lane arterial road running east and west to the south of the Development. Ashford Road is a primary access road from Yonge Street to St. Peter’s Catholic Secondary School, Saint John Paul II Separate School, and the surrounding residential area. Ashford Road runs north of Yonge Street and is to the east of the development. Residential side roads Kenneth Avenue and Montgomery Drive are located to the north and west of the Development. The land to the south of the Development, across the street from Yonge Street, is zoned for a commercial shopping centre. A zoning map of the Development location is provided in Appendix B.

3.1 TRANSPORTATION

Sound propagation calculations for the study were conducted in accordance with the methods defined in Ontario Road Noise Analysis Method for Environment and Transportation (ORNAMENT) (MOECC 1989). The analysis was performed using STAMSON V5.04, a computerized implementation of the methods contained in ORNAMENT. The model was created with site-specific parameters determined from the site plan in Appendix A and traffic volume data provided by the City.

Representative receptor locations for the buildings and the outdoor living area (OLA) between rows 2 and 3 were chosen based on their exposure to the roads discussed previously (i.e. locations most impacted by traffic noise). The indoor sound level limit was assessed at the third storey, 7.5 m above grade, for both daytime and nighttime. The OLA sound level limit was assessed during the daytime period, 3 m away from the midpoint of the applicable façade and 1.5 m above grade (as outlined in NPC-300). Points of reception (POR), along with their associated building block and unit numbers, based on the site plan included in the study, are summarized in Table 3-1 and shown in Figure 1.

Noise impacts on the development due to road traffic on Yonge Street and Ashford Drive were assessed. Traffic data for the year 2017 was provided by the City. This information included average annual daily traffic (AADT) counts and a traffic breakdown of 4% commercial and heavy trucks. A typical Ministry of Transportation of Ontario (MTO) day/night traffic split of 90%/10% was assumed. Traffic volume growth rates of 3.5% and 1% were used for Yonge Street and Ashford Drive, respectively. These growth rates were used to determine the projected AADT for the year 2027 (10-year projection as recommended in NPC-300).

Table 3-2 displays the AADTs for the roads, truck breakdown information, forecasted traffic counts, and posted speed limits.

Transportation Assessment Results August 4, 2017


4.0 TRANSPORTATION ASSESSMENT RESULTS

The predicted noise levels from transportation sources were assessed per MOECC NPC-300. Each noise source was assessed at the most impacted points of reception as shown in Figure 1.

Prediction results for the outdoor plane of window during the daytime and nighttime periods are presented in Table 4-1. The most basic building construction allowed under the Ontario Building Code (OBC) is expected to achieve a noise reduction of 20 dB between outdoor and indoor sound levels. However, to be conservative, the indoor sound level was assumed to be 10 dB less than that predicted at the outdoor plane of window. These prediction results are provided in Table 4-1 for PORs representing dwelling units (POR01 to POR10) and Table 4-2 for the OLA (POR11) during the daytime period.

Sound level predictions for the representative point of reception locations are provided in Appendix C as an output of STAMSON.

Discussion and Recommendations August 4, 2017


5.0 DISCUSSION AND RECOMMENDATIONS

Based on MOECC’s criteria, dwelling unit mitigation measures are not recommended for daytime levels less than 55 dBA. However, sound levels greater than 55 dBA and less than 65 dBA, the guideline recommends providing forced air ventilation with provisions for central air conditioning, warning clauses, and building material meeting minimum Ontario building code requirements (OBC). For sound levels greater than 65 dBA, central air-conditioning and warnings clauses along with building material selected to meet the indoor levels are recommended.

Table 5-1 indicates whether warning clauses, forced air heating, central air conditioning, or building components in excess of the OBC minimum are recommended.

Based on MOECC’s criteria, OLA mitigation measures are not recommended for daytime sound levels less than 55 dBA. However, for sound levels greater than 55 dBA and less than or equal to 60 dBA, the guideline recommends either prospective buyers be notified of potential the noise through warning clauses, or noise control measure be implemented to reduce the sound level to 55 dBA. For sound levels greater than 60 dBA, noise control measures should be implemented to reduce the level to 55 dBA. In cases where noise control measures are not feasible due to technical, economic or administrative reasons, the sound level may exceed 55 dBA. However, in such cases, a sound level in excess of 60 dBA would not be acceptable. Table 5-2 indicates whether noise warning clauses and/or mitigation measures are recommended.

5.1 RECOMMENDATIONS

Recommendations to control the impact road traffic has on the Development are discussed below.

5.1.1 Exterior Wall

For the development, exterior walls exceeding the OBC’s minimum requirements are required for the east and south walls of units in Block E and the west and south walls for units in Block F. This is due to the elevated sound levels from Yonge Street. It is recommended an exterior assembly providing a STC 40 rating or better should be included for all buildings.

5.1.2 Window Assembly

It is recommended that window glazing assembly providing a STC 30 rating or better should be included for all buildings. Typically, window assemblies include a small operable portion within the window assembly. Good weather seals should be included for this operable portion to minimize the noise flanking.

5.1.3 Ventilation

It is recommended that all units within the Development are provided with central air conditioning to allow windows and exterior door to remain closed.




5.1.4 Noise Warning Clause

Based on the study results for the PORs representing dwelling units (POR01 to POR10), it is recommended that the warning clauses be included in all offers of purchase and sale, and lease or rental agreements to comply with NPC-300. The study results for the OLA (POR11) affords the option of either mitigation or providing notice to prospective purchasers or tenants using a noise warning clause to comply with NPC-300. It is recommended that a noise warning clause be selected to be included in all offers of purchase and sale, and lease or rental agreements.

Appropriate wording for the noise warning clauses is provided below and can be altered as required by the City.

Noise Warning Clause for All Blocks (Type A):

“Purchasers/tenants are advised that sound levels due to increasing road traffic may occasionally interfere with some activities of the dwelling occupants as the sound levels exceed the sound level limits of the City of Barrie and the Ministry of the Environment and Climate Change.”

Noise Warning Clause for All Blocks (Type D):

“This dwelling unit has been supplied with a central air conditioning system which will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the sound level limits of the City of Barrie and the Ministry of the Environment and Climate Change.”


Conclusions And Closure August 4, 2017


6.0 CONCLUSIONS AND CLOSURE

Based on the result of this noise impact study it is concluded that Ashford and Yonge Developments Limited’s proposed development can be constructed in compliance with the MOECC’s noise objectives with the implementation of the following recommendations:

• Incorporate central air conditioning. Noise Warning clauses as described in Section 5.0 should be included in pertinent Offers of Purchase or Sale and Lease or Rental Agreements.

• Detailed plans should be reviewed to confirm that no balcony (outdoor living area) greater than 4 m in depth or additional amenity areas are provided within the development

• Preliminary exterior wall and window assembly is discussed within this report and should be confirmed based on final layout plans.

• An acoustical engineer registered to practice in the Province of Ontario or approved professional from the City’s building department must certify that the building plan includes all required noise controls.

Once the site plan is finalized, including building floor plan and suites layout plans, this noise impact feasibility study should be updated with a detailed noise impact study.

This report has been prepared on behalf of Ashford and Yonge Developments Limited (the Client). The analysis and conclusions highlighted in this report are based on information obtained from the Client and their representatives. This assessment represents the information available and provided at the time of assessment and the conclusions are the best judgment of the assessor based on current environmental standards. Stantec Consulting Ltd. attests that to the best of our knowledge, the information presented in this report is accurate.
