1 NOISE IMPACT ASSESSMENT FOR SITE PLAN APPROVAL 47 HAVELOCK STREET OTTAWA, ON. REPORT PREPARED FOR SURFACE DEVELOPMENTS 61 FOREST HILL AVE. OTTAWA, ON, K2C 1P7 March 25,

2 1 NOISE IMPACT ASSESSMENT SURFACE DEVELOPMENTS 1.0 BACKGROUND A new 4-story residential complex constructed by Surface Developments has been planned at the corner of Greenfield Avenue and Havelock Street. The City of Ottawa requires a Noise Impact Assessment as part of the Site Plan Approval for the complex. Transportation routes within the influence zone of the proposed property include Havelock St. (Local Access Road), Greenfield Ave. (2-Lane Urban Arterial), Main St. (2-Lane Urban Arterial), and the Queensway (Divided Highway). The site lies to the north of the City of Ottawa Airport; however, it is outside the noise contours provided for that airport. Therefore, no consideration of airport noise is required. There are no railway lines within the influence distance of the development, so railway noise has not been considered. In summary, the noise sources that need to be taken into account for this development are: Greenfield Ave 2-Lane Urban Arterial Main St. 2-Lane Urban Arterial Queensway Divided Highway This study has been prepared in accordance with the City of Ottawa Environmental Noise Control Guidelines and the Ontario Ministry of the Environment Guideline NPC NOISE LEVELS AT SOURCE The noise levels from road traffic are determined by the number of lanes in a roadway, the type of roadway, and the posted speed limit. The type of roadway specifies the mix of vehicle types using that road during both day and night. Table 1 below taken from the Ottawa guidelines shows the data relevant to Greenfield Ave., Main St. and the Queensway. TABLE 1 ROAD DEFINITIONS AND RELATED TRAFFIC DATA Row Width(m) NA Implied Roadway Class Freeway, Queensway, Highway 2-Lane Urban Arterial AADT Vehicles /Day 18,333 per lane Posted Speed Km/h Day/Night Split % Medium Trucks % Heavy Trucks % / , /8 7 5

3 2 For roads that are close to the receiver locations (distance from road centreline to receiver less than 50m), it is necessary to divide the traffic volumes into the two directions on the road. In the case, where the distance from the source to the receiver is greater than 50m, the source can be located at the centreline of the roadway as the reduction in the calculated noise level at the receiver will be less than 0.5 db. Since the minimum noise source/receiver distance allowed in the STAMSON model is 15 metres, the noise at most receivers can be calculated by STAMSON using the centreline model with difference of less than half a decibel from the two-lane model, and less than 0.1 db at receiver distances beyond 45 metres from the centreline. For the purposes of this study, the calculations performed on Greenfield and the Queensway have been divided into the two directions method, while the calculations performed on Main Street have been calculated using the centreline method. For all roads, it has been assumed that the traffic volumes are equal (half the AADT) in two directions along the directional lane centrelines. When noise barriers are used, elevation differences between the roadway, the barrier base, and the receiver location also affect the noise level at the receiver. Noise at all windows and outdoor living areas must take into account the elevation of that area above the ground. Table 2 shows the traffic volumes from Table 1 divided into day and night traffic and separated into automobiles, medium trucks, and heavy trucks according to the percentages giving in Table 1. TABLE 2 TRAFFIC VOLUME ALLOCATIONS Street AADT Day (0700h to 2259h) Night (2300h to 0659h) Medium Heavy Medium Automobiles Trucks Trucks Trucks Automobiles Heavy Trucks Greenfield Ave. 15,000 13, , Main St. 15,000 13, , Queensway 146, , ,747 5, The traffic speed on Main St. and Greenfield Ave. were set to 50 km/h and the Queensway was set at 100 km/h which are the posted speed limits for the respected roadways. This data was input into the traffic noise model STAMSON 5.1 to calculate noise levels at the various receiver locations. 3.0 NOISE LEVEL AT RECEIVERS The criteria for acceptability and remedial actions require noise levels to be calculated in Outdoor Living Areas (OLAs), and in the plane of the windows in Living Rooms, Dining Rooms, Bedrooms, or any other rooms that may be used for similar activities as in these rooms. The OLA noise criteria is the 16-hour Equivalent Noise Level (Leq 16Hr ) the noise level averaged over the daytime period from 0700h to 2259h (7:00AM to 10:59PM). The criteria for noise in Living Rooms and Dining Rooms (or similar rooms) are also based on the daytime 16-hour Leq. For Bedrooms, the acceptability criterion is based on the 8-hour Equivalent Noise level (Leq 8Hr)

4 3 the noise level averaged over the night-time period from 2300h to 0659h (11:00PM to 6:59AM). It is not necessary to calculate the noise level at every window or wall in the proposed building. Calculation of noise levels at several receiver locations along a wall permits interpolation of noises levels at other points along the wall which are then the impact noise at those locations. For walls whose dimensions are small compared to the noise prorogation distance from the road source, calculation of impacting noise at the ends of the wall is usually sufficient; for walls that are close to the roadways or are irregular in plan view, more calculation points need to be taken, particularly if the irregularities in the wall planform would provide extensive shielding of some portions of the walls and windows. Where a receiver is exposed to more than one of the roadway noise sources, the total noise from all sources was calculated by the STAMSON model. Currently this development does not provide any areas that would be considered OLA. Table 3 below shows the noise levels at the chosen representative locations. Figures 1, 2, and 3 shows the perpendicular distance from each of these receivers to the source roadway and the limiting sight lines that include the section creating the road noise. The STAMSON model has been calculated using a reflective ground surface everywhere and therefore the indicated noise levels are equal for all heights on the building at each calculation point. TABLE 3 STAMSON MODEL RESULTS: NOISE LEVELS AT REPRESENTATIVE RECEIVERS Location Day (dba) Night (dba) Point 1 (North West Elevation Red) Point 2 (North West Elevation Blue) Point 3 (East Elevation Red) Point 4 (East Elevation- Blue) Point 5 (South Elevation Red) Point 6 (South Elevation Blue) Tables 4 and 5 lists the criteria of acceptability and required actions for each type of receiver location. Each wall/window receiver location in Table 3 has to be assessed against both living room/dining room criteria (daytime Leq 16hr ) and night time criteria (Leq 8Hr ).

6 5 Table 6 below provides the Warning Clauses TABLE 6 Warning Type Clauses Type Type A Type B Type C Type D Type E Warning Clause "Purchasers/tenants are advised that sound levels due to increasing (road) (Transitway) (rail) (air) traffic may occasionally interfere with some activities of the dwelling occupants as the sound levels exceed the City s and the Ministry of the Environment's noise criteria." "Purchasers/tenants are advised that despite the inclusion of noise control features in the development and within the building units, sound levels due to increasing (road) (Transitway) (rail) (air) traffic may on occasions interfere with some activities of the dwelling occupants as the sound levels exceed the City s and the Ministry of the Environment's noise criteria." "This dwelling unit has been fitted with a forced air heating system and the ducting, etc. was sized to accommodate central air conditioning. Installation of central air conditioning by the occupant will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the City s and the Ministry of the Environment's noise criteria. (Note: The location and installation of the outdoor air conditioning device should be done so as to comply with noise criteria of MOE Publication NPC-216, Residential Air Conditioning Devices and thus minimize the noise impacts both on and in the immediate vicinity of the subject property." "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 City s and the Ministry of the Environment's noise criteria." "Purchasers/tenants are advised that due to the proximity of the adjacent industry (facility) (utility), sound levels from the industry (facility) (utility) may at times be audible The calculated noise levels result in the following requirements: Outdoor Living Areas: Not applicable Living Room/Dining Room (Daytime) Northwest Elevation (Facing Main and Greenfield): Point dba, Point dba Ventilation system must be designed and provide for the installation of central air conditioning and the titles must include the Warning Clause Type D. The building components must be designed to achieve indoor sound level criteria North Side of East Elevation: Point dba Ventilation system must be designed and provide for the installation of central air conditioning and the titles must include the Warning Clause Type D.
