3 J.E. COULTER ASSOCIATED LIMITED INTRODUCTION At the request of Reichmann Seniors Housing Development Corporation, J.E. COULTER ASSOCIATES LIMITED has reviewed the proposed Senior s Residential development at Wellington Ottawa, Ontario (see Appendix A, Figure for Key Plan and Figure for Site Plan). The purpose of this study is to establish noise mitigation measures that may be necessary as a result of transportation noise to satisfy the requirements of the Ministry of the Environment and the City of Ottawa noise guidelines. NOISE CRITERIA The Ministry of the Environment's (MOE) guidelines that apply to a development site such as this are in the guideline Publications NPC-. These are repeated in the City of Ottawa s noise guideline document Environmental Noise Control Guidelines. Transportation Noise Sources For residential buildings, the Ministry's ventilation requirements are based on the sound level at the exterior building façade. Where the sound levels at the exterior of the building façade exceed db L eq daytime at the living room window, or db L eq night time at the bedroom window, the unit must be provided with forced air heating, with a provision for future installation of air-conditioning by the owner. An excess up to db is permissible, provided a warning clause is given. Where the sound levels exceed this limit (i.e., db daytime or db night time), air conditioning must be incorporated into the building prior to occupancy. Warning clauses are applicable as well. This development is located well outside of the NEF for aircraft noise generated by the Ottawa Airport. Thus, there are no further requirements for this transportation source. Table below gives a summary of the above criteria. Table : Noise Criteria Living Area Daytime L eq (dba) (-) Night Time L eq (dba) (-) Bedrooms -- Living/Dining -- Offices/Reception Areas -- Patios (up to with warning clause) --

4 J.E. COULTER ASSOCIATED LIMITED An outdoor living area is used in reference to a private outdoor patio (m or more in depth) or backyard. In this development, there are no outdoor living areas greater than m in depth that would be exposed to roadway traffic. NOISE SOURCES Transportation Sources The potential transportation noise concerns for this proposed development are the traffic sound levels from Parkdale Avenue to the west and Wellington Street West to the north. Based on the City of Ottawa s Environmental Noise Control Guidelines, Parkdale Avenue and Wellington Street West will carry the following ultimate traffic volumes shown in Table below. Table : Ultimate Traffic Volumes Roadway Ultimate AADT (Veh/Day) Truck Percentage Medium Heavy Day/Night Split (%) Posted Speed Limit Parkdale, % % / kph Wellington, % % / kph The City of Ottawa s Environmental Noise Control Guidelines overestimate the percentage of trucks on the two roadways. Using the Public Works Traffic Services data, provided by IBI Group, trucks accounted for % of the total traffic on Parkdale and Wellington St W. As a result, we have used.% for both Medium and Heavy trucks in the calculation of the roadway sound levels. This still overestimates the total number of trucks on the two roadways and so also inflates the predicted sound levels.. Table : Current Traffic Volumes Roadway Ultimate AADT (Veh/Day) Truck Percentage Medium Heavy Day/Night Split (%) Posted Speed Limit Parkdale,.%.% / kph Wellington,.%.% / kph Stationary Noise Sources There are no significant stationary sources near the site.

5 J.E. COULTER ASSOCIATED LIMITED PROJECTED SOUND LEVELS The MOE's ORNAMENT noise prediction procedure (STAMSON version. computer programme) was used to predict the sound levels. STAMSON. uses the daily traffic volumes for the road and basic topographical information for the site in its calculations (see Appendix B). Table, below, provides the projected sound levels at the west façade of the corner units exposed to both arterial roadways. As Parkdale and Wellington have the same ultimate road volume, the north façade will see the same total noise levels as the west façade. Sound levels were calculated at the corner units as they are the most impacted with noise from both roadways. If MOE s requirements are met at these units, all other units will meet the criteria. The sound levels reported in Table include the effects of the actual truck volumes on Parkdale and Wellington. The sound levels at other points of the building will be lower. Table : Projected Sound Levels Daytime Sound Level, L eq dba Nighttime Sound Level, L eq dba Parkdale Avenue Wellington St W AL Parkdale Avenue Wellington St W AL IMPACT OF THE DEVELOPMENT The mechanical equipment selection for this building has not been finalized. The mechanical equipment should be designed to ensure the Stationary Noise Source guidelines in NPC- and the City of Ottawa guidelines are met at both the development itself and nearby sensitive receptors. It is not expected that there will be any noise impacts provided the development can ensure there is no impact on itself. VENTILATION AND WARNING CLAUSE REQUIREMENTS The combined sound levels generated by Parkdale Avenue and Wellington St W are greater than db L eq daytime and db L eq night time with both current and projected traffic volumes. As a result, MOE requires installation of central air conditioning prior to occupancy. The sound levels are above MOE s noise criteria such that a warning clause is required for all occupancy agreements. The warning clause must be inserted into the Occupancy Agreements for those affected units as noted above, indicating that the sound levels will exceed MOE's noise guidelines. The air-conditioning requirement can be met through centrally supplying cool air to the entire

6 J.E. COULTER ASSOCIATED LIMITED building or by providing individual air-conditioning systems to each unit. Window mounted airconditioners would not be acceptable. The following warning clauses should be included as summarized in the City s guidelines: Warning Clause : Purchasers/tenants are advised that sound levels due to increasing road traffic may occasionally interfere with some outdoor activities as the sound levels may exceed the sound level limits of the City and the Ministry of the Environment. Warning Clause : This dwelling unit has been supplied with a central air conditioning system and other measures 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 and the Ministry of the Environment FAÇADE COMPONENTS To meet the MOE s interior sound level requirement of db L eq night time for bedrooms and db L eq daytime for living room areas, no special glazing is necessary. Based on an fixed and operable, double glazed window, with mm double glazing and a mm air gap between the panes (minimum OBC rating), the interior sound levels will meet both the day and night-time MOE noise criteria. This window configuration corresponds to an STC construction. These are not special construction requirements for the exterior façade as they are fairly typical for a building of this size and height. We would expect that mm double glazing would be provided in any case. CONCLUSIONS The analysis indicates a modest impact from traffic noise at the proposed development of a seniors residence. It is feasible to meet MOE s noise criteria using standard measures found at many residential buildings. Noise control measures including the installation of central air conditioning prior to occupancy and warning clauses to deal with traffic noise will be required to satisfy the various noise criteria. There are no outdoor areas greater than m in depth that would be affected by traffic noise. It is feasible to satisfy MOE s NPC- and the City s Environmental Noise Control Guidelines with the recommended noise control measures in place. RECOMMENDATIONS To meet the current noise guidelines of the Ministry of the Environment and the City of Ottawa, the following recommendations are proposed:. It is recommended all units be equipped with central air conditioning as per MOE

7 J.E. COULTER ASSOCIATED LIMITED guidelines. Air-conditioning can be provided individually to each unit or via a building central system. Window mounted air-conditioning units would not be acceptable.. The following two warning clauses should be inserted into the agreements of purchase and sale or lease: Warning Clause : Purchasers/tenants are advised that sound levels due to increasing road traffic may occasionally interfere with some outdoor activities as the sound levels may exceed the sound level limits of the City and the Ministry of the Environment. Warning Clause : This dwelling unit has been supplied with a central air conditioning system and other measures 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 and the Ministry of the Environment. All units will require a minimum of STC fixed windows and STC operable windows in all rooms; this corresponds to windows that have a mm glass, mm spacing and mm glass [()]. This is typical glazing in any case and not an onerous requirement.
