INTRODUCTION

At the request of Westfield Village Estates Inc., Development Engineering (London) Limited (DevEng) has undertaken the following noise assessment of the proposed twelve (12) unit residential development to be constructed at 3086 Tillmann Road Street in London, Ontario. The corporation of the City of London has indicated that a noise study will be required to determine the effects of vehicular traffic from Southdale Road West on the proposed development. This report has been prepared to address that condition. The purpose of this report will be, therefore, to assess noise levels resulting from road traffic on Southdale Road West, and offer recommendations for their mitigation, if required.

NOISE STUDY PARAMETERS

The Ministry of the Environment and Climate Change Ontario (MOECC) has created explicit criteria regarding what levels of noise are acceptable within residential developments, and what measures are to be taken, should these criteria be exceeded. These guidelines, as outlined in the Environmental Noise Guideline: Stationary and Transportation Sources – Approval and Planning (Publication NPC-300), are as follows: - Maximum outdoor noise level - 55 dbA as measured in the Outdoor Living area between the hours

of 0700 and 2300 (7:00 am and 11:00 pm); - When this criterion is met, no abatement measures are required; - If the outdoor noise level is greater than 55 dbA and less than 60 dbA, physical control measures

may be applied to reduce the sound level to 55 dbA. If no physical measures are provided, the prospective purchasers or tenants must be made aware of potential problems through a suitable noise warning clause;

- When this criterion is exceeded by 5 dbA or more, future tenants must be made aware of potential problems through a suitable noise warning clause, and physical abatement measures are required;

- Maximum indoor road noise level: 45 dbA as measured at the plane of the open living room window between the hours of 0700 and 2300 (7:00 am and 11:00 pm, day-time);

and/or : 40 dbA as measured at the plane of the open bedroom window between the hours of 2300 and 0700 (11:00 pm and 7:00 am, night-time).

- When the above criteria are met, no abatement measures are required; - When the above criteria is exceeded by 1 to 10 dbA, it is required to design the dwelling with a

provision for future installation of central air conditioning. This requirement usually implies forced air heating with the ducts sized for central air conditioning. Future tenants must also be made aware of potential road noise through a suitable warning clause; and,

- When the above criteria is exceeded by more than 10 dbA installation of central air conditioning is mandatory, and exterior building components must be specified.

Noise levels are to be predicted through the use of the MOECC's model, "Stamson, 5.0", utilizing road traffic data as supplied by the City of London.

NOISE SOURCES

3.1 ROAD TRAFFIC DATA

Road traffic frequencies are summarized below in Table 1. The average annual daily traffic (AADT) for Southdale Road West is 36,000 vehicles/day with 3.0% heavy truck traffic and a 90/10 day/night split, as obtained from the City of London Transportation Division. The figures represent the average annual daily road volumes based on the City of London Master Transportation Study. Correspondence with the City of London is included in Appendix A. Table 1- Road Traffic Data

NOISE LEVEL PREDICTIONS

Utilizing the MOECC’s noise prediction model, the projected noise levels for the site were calculated for two sample times during the daylight hours of 0700 to 2300 (7:00 a.m. to 11:00 p.m.) and the night time hours of 2300-0700 (11:00 p.m. to 7:00 a.m.). A `barrier free' situation was assumed for all calculations due to the existing topography. For all calculations the intervening topography and the distance to the noise source were considered as the only other impediments to noise transmission. In addition, the following assumptions were made: - The proposed units will have setbacks as per the attached noise study figure (see Figure 1); - All units will be assumed to be two (2) storeys; - Indoor daytime and night-time receiver elevations are as identified on Figure 1; and, - Outdoor daytime receiver elevation was assumed to be 1.5 m and are located 3 m from the rear façade of the units.

ATTENUATION RECOMMENDATIONS & SUMMARY

5.1 INTERIOR NOISE LEVELS

As per Table 2, some unit’s indoor noise level exceed the MOECC criteria. For those units whose maximum predicted indoor noise level exceed the guidelines by 1-10 dBA, an appropriate warning clause should be applied. In addition, provisions must be made for the future installation of central air conditioning. This can be achieved through providing a forced air heating system adequately sized to allow such an installation thus enabling occupants the ability to close their windows should they find noise levels too much of a nuisance. It is recommended the following warning clause should be applied and provisions for central air conditioning provided for unit 12 exclusively within the proposed development. The following warning clause will be included in all agreements of purchase and sale or lease of this dwelling: "This building has been designed with the provision for adding central air conditioning at the occupant’s discretion. Installation of central air conditioning by the occupant in low and medium density developments will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the sound level limits of the Municipality and the Ministry of Environment. (Note: The location and installation of the outdoor air conditioning device should be done so as to minimize the noise impacts and comply with criteria of MOECC Publication NPC-216, Residential Air Conditioning Devices.)"

5.2 BUILDING COMPONENTS

As per Table 2, indoor noise levels do not exceed the MOECC criteria by more than 10 dBA in either the day or night-time scenarios for any of the dwellings within the proposed development. As such, specialized building components are not required for this development.

5.3 EXTERIOR NOISE LEVELS

The outdoor noise levels, as presented in Table 2, are in excess of MOECC guidelines in some locations and will therefore require additional mitigation measures. When maximum predicted noise levels exceed these guidelines by 1-5 dbA, the provision to notify the potential occupant with the appropriate warning clause is required. The following warning clause should be applied to unit 12 exclusively within the proposed development. This warning clause will be included in all agreements of purchase and sale or lease of this dwelling. "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 Municipality and the Ministry of Environment." A wording similar to the following should also be included in all agreements of purchase of sale or lease of the building: “The City of London assumes no responsibility for noise issues which may arise from the existing or increased traffic on Southdale Road West as it relates to the interior or outdoor living areas of any dwelling within the development. The City of London will not be responsible for constructing any form of noise mitigation for this development.” Proper implementation of the abatement program above will result in noise levels that will meet the MOECC’s requirements for this development.
