Section O Noise Criteria

Transcription

1 01 INTRODUCTION Noise is recognized as an environmental impact and a type of pollution that can negatively affect public health and a community s quality of life. It can impact property values, disrupt peaceful neighborhoods and reduce the attractiveness of cultural institutions, parks, recreation centres and natural areas. Noise generated by road traffic, railway, air traffic and other stationary sources cannot be eliminated but it can be managed by putting in place effective noise mitigation measures. The City of Markham (City) recognizes that excessive noise generated by various sources is an environmental concern that must be addressed through the planning and development application processes. This document provides general guidelines of the City with respect to noise criteria for planning of sensitive land uses under the Planning Act. These guidelines, however, are only general and do not relieve the Acoustic Consulting Engineer and the Developer/Owner of the responsibility for submitting a final design that satisfies and is consistent with the Ministry of Environment (MOE) Environmental Noise Guidelines and meets the City s requirements contained in this document. It is the Developer s/owner's responsibility to ensure that all applicable sound level criteria, as per the MOE guidelines, are met. This includes determining the feasibility of the project, assessing outdoor and indoor acoustic environments and ensuring that the required control measures and necessary noise warning clauses, satisfying the noise requirements, are incorporated in the development. The City relies on the expert opinion of the Owner s Acoustic Consulting Engineer to ensure that the development meets all applicable legislation and guidelines. Where the City s Noise Criteria differ from the MOE guidelines, the more stringent criteria shall apply. NOTE: The noise study report shall be prepared as per the Outline of Detailed Noise Study (Attachment F ). Acoustic Consulting Engineer s Certificate (Attachment B ) must be included in the noise study report, between the Cover Page and the Table of Contents. 02 THE PREFERRED APPROACH The preferred approach, during the planning stage, is the use of passive noise mitigation measures, including but not limited to: Increased building setbacks Residential front lotting Street layout and design considerations that minimize noise mitigation measures Building siting to provide protected outdoor recreational space Building construction including materials for acoustical insulation, glazing, ventilation and other appropriate noise attenuation measures Buffering with noise insensitive land uses Mitigation at noise source for stationary noise sources Noise barriers can be effective at reducing sound levels but can have negative aesthetic impacts on the surrounding neighborhood. As such, noise barriers shall only be used if other measures, identified above, are not feasible or the required sound level cannot be achieved using such measures; written justification shall be provided for acceptance by the City. Noise barriers (including foundations), if constructed, shall be entirely on the private property. City of Markham Section O-1 April, 2014 (Rev 2)

2 The final selection of appropriate noise attenuation measures in each situation needs to be balanced with other development and design considerations. 03 NOISE POLICIES 1. The provisions in the Planning Act require the Approval Authorities (Municipalities) to have regard to matters of provincial interest, one of which is environmental noise. 2. The 2005 Provincial Policy Statement relevant to environmental noise includes: 1.1.1(c) avoiding development and land-use patterns which may cause environmental or public health and safety concerns (c) planning for, protecting and preserving employment areas for current and future uses (e) planning so that major facilities (such as airports, transportation/transit/rail infrastructure and corridors, intermodal facilities, sewage treatment facilities, waste management systems, oil and gas pipelines, industries and resource extraction activities) and sensitive land uses are appropriately designed, buffered and/or separated from each other to prevent adverse effects from odour, noise and other contaminants, and minimize risk to public health and safety. 3. The Official Plan policies of the City Section 2.2(c)(iii) states: In consideration of applications for land-use changes or development adjacent to existing and proposed major arterial roads, highways, railway lines, electric power transformer stations and other uses generating significant levels of noise, the Town may require impact studies to be undertaken by a qualified professional and to be completed prior to approval of a development application to determine existing and future anticipated noise levels and approriate attenuation or mitigation measures. 4. The City s Noise By-law ( ), as amended, regulates noise within the City. 5. All MOE guidelines related to noise must be followed; some of the references are given in Section 4 below and shall be used to prepare the Noise Study. Required mitigation measures must take into consideration noise from all sources. 6. For new noise sensitive development, the sound levels shall be assessed from road and rail impacts in accordance with MOE s Nosie Assessment Criteria in Land-Use Planning Publication LU-131 (as amended). 7. It is the Owner s Acoustic Consulting Engineer s responsibility to ensure all applicable legislation and guidelines related to noise are met. City of Markham Section O-2 April, 2014 (Rev 2)

5 06 NEED FOR A NOISE STUDY 1. A Noise Study is normally required, as per the guidelines below, when a noise-sensitive development is located adjacent or in close proximity to the following potential noise sources: a) Within 500 m of a Provincial Highway/Freeway b) Within 250 m of a Regional Road whose future traffic volume may be greater than 4,000 vehicles/day c) Within 100 m of a City road whose future traffic volume may be greater than 4,000 vehicles/day d) Within 500 m of a railway ROW e) Within the 25 NEF contours of an Airport f) Within the potential zone of influence, as defined in MOE documents D-1 and D-6, of a Stationary Source of noise (industrial/commercial/institutional); a detailed noise study is required for developments within the potential influence area of stationary sources. g) Within 500 m of extensive commercial operations (loading docks of supermarkets, large commercial buildings with prominent ventilation and air conditioning equipment, automatic car washes, etc.) h) Within 500 m of aggregate operations (pits, quarries, etc.) i) Any other noise sources not mentioned above 2. If a Noise Study is not required for a development site, a certificate from the Acoustic Consulting Engineer (Attachment A ) shall be submitted to the Director of Engineering identifying the reason(s) that a noise/vibration study is not required and a statement confirming that the development site meets all MOE guidelines for noise. 07 TYPES OF NOISE STUDY 1. Feasibility Noise Study A Feasibility Noise Study is generally required whenever the proposed lands are within the influence area of a stationary noise source. The extend of the influence area is case specific, depending on factors such as the type and scale of the stationary sources, intervening topography and intervening land uses. A Feasibility Noise Study is required prior to approvals of the Official Plan Amendment and Draft Plan of Subdivision Applications. It is required under any of the following conditions: a) The sound levels resulting from surface transportation noise affecting the proposed development exceed the noise criteria. b) The proposed developments are within the setback distances or potential influence zone of influence outlined in Section 06 of this document. City of Markham Section O-5 April, 2014 (Rev 2)

6 c) The grade elevations are favorable to permit installation of future noise control measures. The study shall be prepared by an Acoustic Consulting Engineer and shall include, but not limited to, the following information: d) Report identifying noise control alternatives or strategies. e) Typical building components specifications (types of wall, windows, etc.) f) Approximate noise barrier height and its location g) Traffic volume to be based on ultimate road traffic data. The traffic data collected is valid for is two (2) years for traffic, one (1) year for railway and one(1) year for stationery h) Recommendations and implementation procedures 2. Detailed Noise Study A Detailed Noise Study is generally required whenever the proposed lands are within the influence area of a stationary noise source. The extend of the influence area is case specific, depending on factors such as the type and scale of the stationary sources, intervening topography and intervening land uses. A Detailed Noise Study is required prior to approvals of Site Plans and Registration of M-Plans of Subdivision for clearing conditions of draft approvals. It is required under any of the following conditions: a) The sound levels resulting from surface transportation noise affecting the proposed developments exceed the noise criteria, the following tables for barrier heights to achieve Leq 55 dba in OLA s is required: Receptor OLA Sound Level Barrier, Leq, dba Barrier Height (m) to Achieve the Following Leg, dba Receptor Code Elevations (m) At Source Receiver Barrier Base Top of Barrier Barrier Elev. Relative to House Ground Base Elev. Height of Barrier (m) b) The proposed developments are within 500 m of a freeway ROW or 250 m of a provincial highway ROW, or 100 m of the ROW of other roads City of Markham Section O-6 April, 2014 (Rev 2)

7 c) The proposed developments are within 500 m of a Principal Main Railway Line or 250 m of a Secondary Main Railway Line or 100 m of other railway lines d) The proposed developments are within the potential influence area of stationary sources e) The Acoustic Consulting Engineer shall confirm with the Consulting Design Engineer the final grading elevations are used for the proposed noise control measures The study shall be prepared by an Acoustic Consulting Engineer and shall include the Outline given in Attachment F 08 ENVIRONMENTAL NOISE CRITERIA The environmental noise guidelines of the Ministry of the Environment, as outlined in Publication LU-131 for residential developments, shall be used in the City and are summarized below. 1. Road Traffic a) Indoors If the nighttime (11:00 p.m. to 7:00 a.m.) sound levels (Leq Night) at the exterior face of a bedroom window exceed 60 dba or if the daytime (7:00 a.m. to 11:00 p.m.) sound levels (Leq Day) at the exterior face of a living/dining room window exceed 65 dba, means must be provided so that windows can be kept closed for noise control purposes. This typically requires installation of central air-conditioning. A warning clause is required and must be included in all Agreements of Purchase & Sale, Lease Agreements and Subdivision/Site Plan Agreements. If the nighttime sound levels at the exterior face of a bedroom window are between 51 and 60 dba inclusive or if the daytime sound levels at the exterior face of a living/dining room window are between 56 and 65 dba inclusive, provisions must be available for adding central airconditioning by the occupant at a later date. This typically involves a ducted heating system suitably sized to accommodate the addition of central air-conditioning by the occupant at a later date. A warning clause is required and must be included in all Agreements of Purchase & Sale, Lease Agreements and Subdivision/Site Plan Agreements. In all cases, the air-cooled condenser unit must not exceed an AHRI sound rating of 7.6 bels and must comply with the City s Noise By-law. For indoor areas, the nighttime sound levels guideline for bedrooms is 40 dba and daytime sound levels guideline for living/dining room is 45 dba. These criteria are used to determine the architectural requirements. For the purposes of noise impact assessment in the plane of a bedroom window, the point of assessment shall typically be 2.5 m above ground for ground floor rooms and 4.5 m above ground for second storey rooms (or higher as appropriate for the site specific case) unless the dwelling is a multi-storey building. City of Markham Section O-7 April, 2014 (Rev 2)

8 b) Outdoors For the outdoor amenity areas (Outdoor Living Areas - OLAs), daytime sound levels guideline for road and rail traffic is 55 dba. If the daytime sound levels is less than or equal to 55 dba, no control measures or warning clauses are required. If the daytime sound levels are greater than 55 dba and less than or equal to 60 dba, physical control measures (such as a noise barrier) are required to reduce the sound level to 55 dba. If physical measures are proven (by Acoustic Consulting Engineer, Consulting Design Engineer and Architect/Planner) the not to be technically and economically feasible then a warning clause is required and must be included in all Agreements of Purchase & Sale Lease Agreements and Subdivision/Site Plan Agreements. Note: Amenity Areas such as balconies, terraces, rooftop decks and decks/terraces above garages, etc. that are less than 4.0 m deep are not considered OLA requiring acoustical protection. For the purposes of noise impact assessment in an OLA, the point of assessment shall typically be up to 3.0 m from the building facade and 1.5 m above ground. For developments adjacent to rail lines, safety berms (height and materials) shall be as required by the railway authorities. For both indoor and outdoor conditions, where the acoustical criteria are exceeded, warning clauses must be placed in Agreements of Purchase and Sale, Lease Agreements and Subdivision/Site Plan Agreements. 2. Aircraft Traffic If the NEF/NEP (Noise Exposure Forecast/Noise Exposure Projection) contour value is below 25, no further assessment is required. If the NEF/NEP contour value, during 24 hours time period, is between 25 and 29 inclusive, alternate means of ventilation (e.g. forced air with provision of AC) and warning clauses are required in all Agreements of Purchase & Sale Lease Agreements and Subdivision/Site Plan Agreements. In addition, building components must be designed to achieve the indoor sound level criteria. According to the MOE guidelines and the Provincial Policy, redevelopment of existing residential uses and other sensitive land uses or infilling of residential and other sensitive land uses may be considered above NEF/NEP 30 if the municipality supports the application and it has been demonstrated that there will be no negative impacts on the long term function of the airport. If the municipality approves the development in the NEF/NEP 30 and above, mandatory central air conditioning, acoustically designed building components and warning clauses shall be included in all Agreements of Purchase & Sale Lease Agreements and Subdivision/Site Plan Agreements. City of Markham Section O-8 April, 2014 (Rev 2)

9 The MOE indoor criteria for aircraft noise are NEF/NEP 0 for the bedrooms and NEF/NEP 5 for living rooms and other habitable rooms, as per the following table: Type of Space Indoor NEF/NEP General Offices, reception areas, retail stores, etc. 15 Individual or semi-private offices, conference rooms, etc. 10 Living/dining areas of residences, sleeping quarters of hotels/motels, theatres, libraries, schools, day-care centres, places of worships, etc. Sleeping quarters of residences, hospitals, nursing/retirement homes, etc Stationary Sources The MOE has published two documents: LU-131 titled "Noise Assessment Criteria in Land-Use Planning, dated October 1997 and NPC-205 titled "Sound Level Limits for Stationary Sources in Class 1 & 2 Areas (Urban)", dated October The most critical hour is the "predictable worst case" noise impact occurs during the hour when the difference between the predicted sound level produced by the stationary source and the background sound level of the natural environment or the applicable sound level criteria is at a maximum. If the guidelines are exceeded, the MOE noise guidelines require mitigation measures, preferably at the source. The continuous sounds from the stationary source are measured in terms of Leq, the energy equivalent continuous sound level over a defined time period, in this case, one hour. The impulsive sounds from the stationary source are measured in terms of logarithmic average sound level (LLM) expressed in dbai. The MOE recognizes the need for back-up beepers/alarms as safety devices and as such does not have any guidelines or criteria to address these sources. It should be noted that the MOE guidelines and the City s Noise By-law do not require that the source be inaudible, but rather that specific sound level limits be achieved. a) LU-131 This document outlines the MOE noise criteria for the planning of sensitive land uses adjacent to transportation sources and existing stationary sources. It provides definitions of the sources, including stationary sources of noise and sets sound level limits to be achieved at the residential receptors. With respect to stationary sources of noise in urban areas, the MOE guidelines require that the sound levels due to the stationary source not exceed the sound levels due to road traffic in any hour of source operation, subject to specific exclusions. The lower limits are 50 dba during daytime hours and 45 dba during the night. In some cases, the MOE may accept a marginal excess not exceeding 5 db. For new residential development adjacent to stationary sources, the provisions of NPC-205 shall be applied. In general, if the criteria for a stationary source of noise are exceeded, the MOE recommends that control be implemented at the source rather than at the receiver. Alternatively, if the receiver is set back from the source or if a physical barrier is constructed so that the criteria can be met at the receiver, no additional mitigative measures are required. In addition, a warning City of Markham Section O-9 April, 2014 (Rev 2)

10 clause in Agreements of Purchase & Sale, Lease Agreements and Subdivision/Site Plan Agreements noting the proximity of houses to such a source should be considered. Treatment of the receptor building by the use of modified wall and window construction and central air conditioning to keep windows closed is not an acceptable solution. Tables 5, 6 and 7 of LU-131 give sound level limits in the plane of a window for daytime and nighttime hours. Publication LU-131 refers to NPC-205 to address the applicable impulse criteria. The sound level produced by the stationary source is to be established using the techniques prescribed in the Model Municipal Noise Control By-Law publication, prepared by the MOE in 1978, including the most current version of NPC-205 (October 1995). b) NPC-205 For planned stationary sources or for complaint investigations, the MOE publication NPC-205 and the City s By-law ( ) apply. NPC-205 requires that specific sound level limits be achieved anywhere on the residential property at all times (day, evening and night). In addition, the MOE guidelines also require that most industries have valid Environmental Compliance Approvals (ECA) to operate. NPC-205 provides the applicable sound level limits for stationary sources to be achieved at residential receptors, including impulsive noise. For impulsive noise the Logarithmic Mean Impulse Sound Level cannot exceed the greater of the One Hour Equivalent Sound Level (L eq ) produced by road traffic or the exclusion limits listed in MOE Table The MOE guidelines also require that sources of noise that have a tonal component or are distinctly identifiable be penalized by a minimum of 5 dba. Quasi-steady impulsive sounds are subject to a 10 dba penalty. City of Markham Section O-10 April, 2014 (Rev 2)

13 11 DESIGN GUIDELINES FOR NOISE BARRIERS 1. Introduction Noise barriers are a noise mitigation measure used for attenuating noise levels either at the source (for noise generating developments) or at the receiver (for noise sensitive developments). The objective of a noise barrier is to reduce the amount of sound energy generated by the source or to divert the flow of sound energy away from the receptor or to shield the receptor from the sound energy. In all cases, the noise barrier shall interrupt the line(s)-of-sight between the receptor and the source(s). The City shall require the Noise Study to include details related to the cost of the proposed noise barrier(s) for financial securities to be secured in the Agreement. In general, the City requires financial securities of $5, per fence up to a maximum of $20, Barrier designs along Regional road shall be consistent with the Region of York policies and along other roads shall be as designed by the structural/geotechnical engineer. The noise fence portion of the noise barrier shall not exceed 2.0 m in height. In addition, the limit of the total noise barrier (berm + noise fence) height shall not exceed 4.5 m above the road centre-line for the ground oriented OLA, where feasible. The noise barrier shall be entirely within the private property and shall be installed within six (6) months of occupancy and/or as directed by the Director of Engineering in writing. 2. Noise Barrier Planning Every effort shall be made to minimize the use of noise barriers, if possible during the early stages of development. The use of noise barriers as attenuation measures shall only be considered where it has been demonstrated that alternative design solutions are not feasible. 3. Noise Barrier Design The design and location of noise barriers shall be carefully planned early on in the development stages. Noise barriers can come in the following forms or a combination: Blocks of buildings or other structure meeting the MOE noise fence density requirements Dense vegetation in 30+ meter buffer area Noise fences Noise berms (or earth berms) Retaining walls The general rules of thumb for the design of noise barriers are given below. However, if these rules cannot be met, other noise control options and loting/design possibilities shall be considered: Should the results of the analysis show the need for noise barriers in excess of 2.0 m high, the drawings shall show the additional buffer space needed to accommodate a berm. Every effort shall be made to maximize the height of berm and limit the height of noise fence to a maximum 2.0 m. City of Markham Section O-13 April, 2014 (Rev 2)

14 The height of the noise barrier above the road centre-line for the ground-oriented OLA shall be no more than 4.5 m. For subdivisions adjacent to railway lines, it shall be 5.5 m, where feasible The minimum usable OLA depth is 6.0 m measured from the building facade to the noise fence (or to the toe of the berm where a berm is used) unless otherwise allowed by the zoning. The land slope for usable OLA shall be between 2.0% to 4.0% An acceptable setback from a noise barrier to a residential building footprint shall be two to four times the height of the barrier. The desirable setback shall be four times or more than the height of the noise barrier In cases where the attenuation facility is interrupted, noise barrier returns and parallel noise barriers may be required. The detailed design and calculations of this type of treatment shall be incorporated into the Noise Report. The Noise Report and the Grading Plans shall include a detailed plan and appropriate cross sections The location of a proposed noise barrier shall be based on the following principles: The noise barrier shall be located entirely on the private property The toe of the barrier footprint (including foundation if there is no berm) shall be a minimum of 0.30 m from the municipal ROW. The location of the noise barrier wall shall also take into consideration the requirements for future roadway widening If the construction of a noise berm on the City or the Regional ROW is deemed acceptable by staff, the crest of a berm shall still be located entirely on the property under construction and inside the property line. The portion of the berm on the municipal or regional ROW shall be subject to acceptance by the City and/or the Region prior to making any commitment to this effect. It is important to remember that the design of the berm can be affected by future roadway widening. The Consulting Engineer must prepare the necessary details related to the berm design and address all matters of concern such as compaction, grade elevations, drainage, safety, cover and landscaping, side slopes, maintenance, etc. to the satisfaction of the City and/or the Region. Concurrence of the design by the City and/or Region must be provided in writing. The noise fence shall generally be located at the crest of the berm. The portion of the berm adjacent to the transportation facility on private property shall be dedicated to the City/Region at no cost, where requested by the City/Region Where a noise barrier is required, the receptors shall be located within its acoustical shadow zone City of Markham Section O-14 April, 2014 (Rev 2)

15 4. Noise Fence Design The maximum accepted height of a noise fence shall be determined in each case by the City staff. The desirable noise fence height is 2.0 m, not including any berms, retaining walls, etc. The City may approve noise fence heights up to 2.5 m subject to site specific review and approval by the City staff. Written documentation shall be provided to the regarding concurrence from the Urban Design group for any noise fence height over 2.0 m. If the desired noise fence heights cannot be met, other noise control options and loting/design possibilities shall be considered. The noise fence shall have the following characteristics: Be of wood, solid with no gaps along its length and having a minimum face density of 20 kg/m2 (4 lb/ft2) or equivalent materials accepted by the Director of Engineering. Noise fence materials acceptable to the City include any, or combination of: Wood (mainly residential application) The following other materials may be considered but shall require prior acceptance from the Director of Engineering: Precast concrete panels (non-residential application) Precast concrete sections (non-residential application) Brick (any application) Steel panels and steel structural sections (non-residential application) Vinyl and recycled materials (non-residential application) Composite barrier systems employing a combination of above materials such as: Wood panels and structural steel sections Precast concrete walls and steel sections (non-residential application) A transmission loss of at least 10 dba greater than the barrier effect Any access gates of the same material as the noise fence with a minimum surface density of 20 kg/m 2 and shall seal reasonably, when closed Interrupt the line-of-sight drawn from the source to the receiver, i.e. the receiver shall be in the acoustical shadow zone of the barrier Provide the desired minimum sound level reduction and protect all receiver locations subject to the guidelines Be continuous or is turned through right angles away from the source at both ends to protect the receivers from the sides City of Markham Section O-15 April, 2014 (Rev 2)

16 5. Noise Berm Design A maximum berm slope of 3:1 is required for any earthworks. Slopes steeper than 3:1 may be considered for site specific situations. The berm design and construction details shall be documented in the Noise Study, engineering and landscape submissions. Berm construction shall generally be entirely on the private property. However, as noted above, berm construction may be considered on the City or the Regional property subject to written concurrence from either the City or the Region prior to finalizing the design. The City or the Region may consider dedication of the property outside of the crest of the berm to the City or the Region at no cost where the berm has been entirely built on private property. Where required, a noise fence shall be located at the crest of the berm. Refer to sections O11.1 to O11.3 for berm height related information. 6. Drainage Gaps The MOE discourages gaps under, around or within noise barriers. Its guidelines on this issue are summarized below: All barriers designed for attenuation of sound shall be without gaps and cracks that will reduce the performance of sound attenuation Overland drainage requirements below a barrier may be addressed by minimized and localized drainage gaps It is recommended that the use of drainage gaps under noise barriers is to be discouraged and that alternate design changes be implemented such as: Readjustment of the grades by the Site Engineering Consultant, where feasible The use of swales and drainage ditches to channel the water to less noise-sensitive cases The use of drainage catch basins in backyards The use of design techniques to create interrupted line-of-sight under the barrier wall City of Markham Section O-16 April, 2014 (Rev 2)
