Environmental Noise Feasibility Assessment
Milton Heights Neighbourhood
Century Grove Parcel
Proposed Mixed-Use DevelopmentTown of Milton
1.0 INTRODUCTION
Valcoustics Canada Ltd. (VCL) previously prepared:
• A Noise Feasibility Assessment for the overall Milton Heights Neighbourhood datedNovember 28, 2006 (hereafter referred to as the November 28, 2006 Report – Reference 5);
• An Environmental Noise Feasibility Study dated June 6, 2013 (herein referred to as theRevised Report – Reference 6); and
• Addendum Letter #1 dated November 15, 2013, to address changes to the stationary noisesource analysis only (herein referred to as the Addendum Report – Reference 7).
This Update Report has been prepared to consolidate the current assessment for both thestationary and transportation noise sources, based on the current draft plan layout, analysismodelling parameters and the newly released NPC-300 noise guideline by the Ministry of theEnvironment (MOE). This update has been prepared as a stand-alone report. Content fromprevious report versions that has not changed has not been repeated in the body of this report, forbrevity. However, the salient content has been included in the appendices for reference.
The draft Plan of Subdivision has changed since the Revised Report and the Addendum Reportwere issued. However, in general the concepts for noise mitigation remain the same; i.e., for thetransportation sources the closest dwellings to New Tremaine Road or Highway 401 will have ventilation requirements and upgraded facade construction. Lots 1 to 5 require sound barriers. Forthe stationary sources, site specific dwelling designs will be used on a portion of the perimeter,which will act as sound barriers and screen the interior of the site from noise.
1.1 PURPOSE
30 Wertheim Court, Unit 25, Richmond Hill, Ontario L4B 1B9 Tel: 905-764-5223 / E-mail: [email protected]
VALCOUSTICS CANADA LTD. Milton Heights Neighbourhood/Century Grove Parcel – Noise Feasibility/Update File: 102-286-300 Page 2
The noise control measures have been updated accounting for changes to the subdivision plan andconfirmed alignment of the New Tremaine Road. In addition, the noise impact assessments fromthe two industrial plants east of the site have been updated based on the modelling parametersprovided by the acoustical consultants working for the Town of Milton, Granite Real Estate Inc., andMagna International Inc. (as per the Reference 8 to 10 materials).
The sound exposures on the site due to the primary transportation and industrial sources havebeen predicted and compared to the applicable MOE noise guideline limits. Where noise excessesabove the guideline limits are predicted to occur, mitigation measures have been recommended.
1.2 SITE AND AREA DESCRIPTION
The Century Grove Parcel is located at the central area of the overall Milton Heights development,on the east side of New Tremaine Road. See Figure 1 for a Key Plan. The proposed developmentis composed of residential lands, a commercial block (Block 35), two business park blocks (Blocks36 and 37), a park block (Block 38), storm water management facilities (Block 39) and the drainagecorridor (Block 40). See Figure 2.
The residential portion of the plan consists of 28 townhouse blocks, one semi-detached block andfive single family dwellings on the south side of Street A, to the west of the park, on Block 38. Theunnumbered, “future block” on the westerly sides of Blocks 32 and 33 and parts of Blocks 31 and34 are under different ownership but have been assessed a s part of this plan. There is an existingheritage dwelling fronting onto Peru Road and another existing residential dwelling closer to theNew Tremaine Road realignment (just east of single family dwelling Lot 5). The proposedresidential portion of the site is surrounded on the north and east sides by the proposed commercialblocks. To the north is commercial Block 35 and to the east are commercial Blocks 36 and 37. These commercial blocks, once constructed, will provide increased acoustical screening from theindustrial facilities to the east.
The site is currently zoned for future development. New Tremaine Road will be realigned with anew interchange at Highway 401. The New Tremaine Road realignment will be along the westboundary of the site. Highway 401 is approximately 380 m to the north.
The report is based on the Draft Plan of Subdivision prepared by Humphries Planning Group Inc.showing latest revised date of April 23, 2014, which is included as Figure 2.
1.3 PROPOSED DWELLINGS
Site specific dwelling designs will be used on the site as part of the noise control concept.
• Residential Blocks 15, 16, 17 and 31 at the south end (north side of Street A), will not havegrade level outdoor amenity spaces (“Outdoor Living Areas” – OLA). The OLA’s will be inthe form of second floor balconies on the north sides of the dwellings. The balconies willbe less than 4 m in depth.
• Residential Blocks 7 and 8 (north side of Street D), at the north end will front toward StreetD and will not have any rear yard amenity space (at the north). The OLA’s will be in theform of second floor balconies on the southern (shielded) sides of the dwellings. Thebalconies will be less than 4 m in depth.

VALCOUSTICS CANADA LTD. Milton Heights Neighbourhood/Century Grove Parcel – Noise Feasibility/Update File: 102-286-300 Page 3
• Residential Blocks 9 to 13 at the eastern periphery (west side of Street B), will be designedsuch that there will be no noise sensitive windows on the northern, eastern or southernfacades. These units will not have rear yard amenity spaces. There will be small (less than4 m in depth) balconies on the west sides.
• At the semi-detached dwellings at Block 14, there will be no noise sensitive windows on thenortherly or easterly facades. The dwellings will not have grade level OLA’s. The OLA’swill be in the form of second floor balconies on the westerly (shielded) sides of thedwellings. The balconies will be less than 4 m in depth.
The townhouse and semi-detached dwellings will be 3-storeys in height. The single familydwellings will be 2-storeys. The receptor heights were chosen in conformance with the MOE noiseguidelines and represent the centre point of the plane of window at each storey of the building. Theheights used were 1.5 m (first storey), 4.5 m (second storey) and 7.5 m (third storey) above grade.
Sample floor plans for the dwellings on Blocks 9 to 13 are included in Appendix A.
1.4 COMMERCIAL BLOCKS
For the purposes of this assessment it has been assumed that the residential portions of the sitewill be developed first. Thus, acoustical screening from the proposed commercial developmentson Blocks 36 and 37 (east side) or Block 35 (north side) have not been considered in the analyses. It is expected that once these developments are constructed, additional acoustical screening wouldbe realized and the predicted sound exposures on site would be less.
2.0 ENVIRONMENTAL NOISE ASSESSMENT – TRANSPORTATION SOURCES
2.1 TRANSPORTATION NOISE SOURCES
The noise sources with the potential for impact on the proposed development are road traffic on:
• Highway 401; and• the realigned New Tremaine Road.
Traffic volumes on the existing Peru Road, No. 3 Sideroad and existing Tremaine Road areinsignificant relative to the other (primary) traffic sources and have not been considered further.
The existing Canadian Pacific Railways (CPR) line to the south is far enough away that it does notrequire consideration.
Road traffic data used in this assessment is summarized in Table 1.
2.2 ENVIRONMENTAL GUIDELINES
2.2.1 MOE – NPC 300
In October 2013, the MOE released the Publication NPC-300 noise guideline (although it is datedAugust 2013). NPC-300 replaces the four existing noise guidelines in Ontario (PublicationsLU-131, NPC-205 and NPC-232, as well as “Noise Assessment Criteria in Land Use Planning:
30 Wertheim Court, Unit 25, Richmond Hill, Ontario L4B 1B9 Tel: 905-764-5223 / E-mail: [email protected]
VALCOUSTICS CANADA LTD. Milton Heights Neighbourhood/Century Grove Parcel – Noise Feasibility/Update File: 102-286-300 Page 4
Requirements, Procedures and Implementation”).
NPC-300 is now the applicable guideline to assess the noise impacts from the transportation noisesources as well as the industrial sites. For the industrial noise assessment, the site remains as aClass 1 area and thus, the numerical guideline limits have not changed from those presented inprevious assessments. The traffic noise criteria also remain the same.
Note, that a balcony/terrace is not considered an OLA unless it is at least 4 m in depth andunenclosed.
The MOE noise guidelines are summarized in Appendix B.
2.2.2 Region of Halton
The Region of Halton Noise Attenuation Technical Policy (Reference 11) sets a maximum 3.0 msound barrier height for sound barriers adjacent to Regional Roads. The acoustical consultantrepresenting the Region of Halton (for this Milton Heights project) indicated that in practice up to3.5 m can be allowable in some cases and that the minimum height of sound barrier is 2.4 m(Reference 12). The policy speaks to the height of the noise barrier "wall", and does not state orimply that the height is inclusive of a berm. In other words, the maximum height relates only to thewall or fence portion, and the overall height including an earth berm (or retaining wall) can exceedthe 3.0 m height. (Note: it is understood that a different consultant is now representing the Region.)
2.2.3 Town of Milton
The sound barrier requirements from the Town of Milton are indicated in the Engineering and ParksStandards dated August 2010 (Reference 13). The sound barrier requirements relate to soundbarriers adjacent to municipal roads and rail lines. Section 1.1.12.2 indicates “The maximum barrierheight shall be 2.0 m, although greater heights can be obtained using a combination berm and wall.Maximum height adjacent to rail lines shall be 3.0 m”. However, it is understood (via an e-maildated January 7, 2014 from the Engineering Services department at the Town) that for this project,a maximum allowable acoustic fence height of 2.4 m to mitigate road traffic noise can be used(Reference 14).
2.3 NOISE IMPACT ASSESSMENT
2.3.1 Road Traffic Sources
Using the road traffic data in Table 1, the sound energy exposures, in terms of Leq Day and Leq Night,were determined using STAMSON V5.04 – ORNAMENT, the computerized road traffic noiseprediction model of the MOE.
The daytime and nighttime predictions were done at the centre of the top storey window of eachbuilding, representing the bedroom windows. For analysis purposes this was 7.5 m above gradefor Blocks 7 to 34, the future block and 4.5 m above grade for Lots 1 to 5.
The highest daytime/nighttime sound exposures of 71 dBA/65 dBA are predicted at the westernfacade of Residential Block 7, closest to New Tremaine Road. The highest daytime soundexposure in an OLA of 65 dBA is predicted to occur at the single family dwelling on Lot 1, sidingtoward New Tremaine Road.

VALCOUSTICS CANADA LTD. Milton Heights Neighbourhood/Century Grove Parcel – Noise Feasibility/Update File: 102-286-300 Page 5
The predicted sound exposures at other blocks/lots would be less than the above due to increasedistance separation or acoustical screening. Table 2 summarizes the predicted sound exposuresat example locations on the site. A sample calculation of the future road traffic sound exposure iscontained in Appendix C.
2.4 NOISE CONTROL MEASURES
The noise control measures for transportation noise sources can generally be classified into twocategories which are interrelated, but which can be treated separately for the most part:
(a) Architectural elements to achieve acceptable indoor noise guidelines;
(b) Design features to protect the OLA’s.
Table 3 and attached notes as well as Figure 2 summarize the noise abatement recommendations.
2.4.1 Exterior Wall and Window Construction
2.4.1.1 Residential Dwellings
Upgraded exterior wall construction above the minimum requirements governed by the OntarioBuilding Code (OBC) should be expected for the dwellings closest to New Tremaine Road.
The required Sound Transmission Class (STC) ratings for the exterior facades were calculatedassuming corner spaces (with windows on two facades) where the windows have a surface areaequalling 20% of the associated room floor area, and exterior walls were assumed to have asurface area equal to 80% of the associated room floor area for walls carrying a window.
For the dwellings at the western periphery of the site, closest to New Tremaine Road, brick veneerexterior wall construction (or STC 54 equivalent) is recommended, and has been assumed whendetermining the exterior window STC requirements. This includes the dwellings on residentialBlocks 7 and 31 and Lot 1.
Assuming the brick veneer (or STC 54 equivalent) exterior wall construction requirement for thedwellings indicated above, window construction meeting the minimum non-acoustical requirementsof the OBC would be sufficient to meet the indoor sound level limits of the MOE. Thus, upgradedwindows are not anticipated to be required. If exterior wall construction of lesser sound isolationis used, upgraded windows may be required.
The exterior wall and window requirements are based on standard assumptions and should bechecked once detailed working drawings are available for the dwellings.
Table 3 summarizes the general architectural exterior wall/window requirements.
2.4.1.2 Commercial Block
The commercial blocks at the north and east ends will include various commercial uses. Specialnoise control requirements are not anticipated to be required for these or similar uses.
30 Wertheim Court, Unit 25, Richmond Hill, Ontario L4B 1B9 Tel: 905-764-5223 / E-mail: [email protected]
VALCOUSTICS CANADA LTD. Milton Heights Neighbourhood/Century Grove Parcel – Noise Feasibility/Update File: 102-286-300 Page 6
Standard 1" (25 mm) sealed, double-glazed units will be sufficient to allow the indoor sound levellimits to be met.
Upgraded exterior wall construction should not be necessary. Standard construction meeting theminimum OBC requirements should be sufficient. This includes glazed or metal spandrel panelsrated at about STC 35 or higher.
2.4.2 Ventilation Requirements
This applies to the residential uses only. There are no acoustically related ventilation requirementsfor commercial uses.
Mandatory air conditioning is required for the townhouse blocks adjacent to New Tremaine Road(Residential Blocks 7, 30, 31, 34, future block and Lot 1). Figure 2 shows which units requiremandatory air conditioning.
Subsequent rows beyond those requiring mandatory central air conditioning will require theprovision to allow the future installation of air conditioning, by the occupant. Figure 2 shows whichunits require this treatment.
For the dwellings along the north and east boundaries (Blocks 8 to 14), central air conditioning isrecommended. This is due in part to exposure to Highway 401, and to also promote greatercompatibility with the industries to the east.
For low and medium density development (singles, semi’s and townhouses), the provision foradding air conditioning normally takes the form of a ducted ventilation system suitably sized toaccommodate the future addition of central air conditioning. It is noted that providing a dwellingwith central air conditioning in the first instance will automatically satisfy the minimum “provision forfuture installation of air conditioning” requirement. Regardless of the noise control requirements,all dwellings in the development are anticipated to be designed with forced air systems.
Figure 2 and Table 3 show the ventilation requirements, including the recommended upgrade tofull air conditioning for the blocks closest to the industries.
2.4.3 Outdoors
This applies to the residential uses only. There are no outdoor (sound barrier) requirements forcommercial uses.
The unmitigated daytime sound exposures at the residential OLA’s for the five single familydwellings at the south end are above the 55 dBA MOE objective guideline limit.
For all locations, sound barrier heights were investigated to achieve the 55 dBA guideline.
The sound barrier requirements are shown on Figure 2, and summarized in Table 3.
To meet the 55 dBA daytime OLA objective sound level limit at Lots 1 to 5, a continuous soundbarrier is required, varying in height (above grade) from:
• 4.3 m at Lot 1;
30 Wertheim Court, Unit 25, Richmond Hill, Ontario L4B 1B9 Tel: 905-764-5223 / E-mail: [email protected]
VALCOUSTICS CANADA LTD. Milton Heights Neighbourhood/Century Grove Parcel – Noise Feasibility/Update File: 102-286-300 Page 7
• 3.4 m at Lot 2;• 2.4 m at Lot 3; and • 1.8 m at Lots 4 and 5.
To meet the Town and Region’s sound barrier height requirements, the sound barrier should becomposed of a maximum 2.4 m high acoustic fence. The additional height would need to be madeup by earthen berms or other grading features. For example, at Lot 1, the sound barrier could bea 2.4 m high sound fence atop a 1.9 m berm (or other grading feature).
The required sound barriers are shown conceptually on Figure 2.
Sound barriers must be of solid construction with no gaps, cracks or holes and must have aminimum surface density of 20 kg/m². A variety of materials are available including wood, masonry,earth berms, or a combination of these or similar materials.
As mentioned, there are no grade level amenity spaces for the dwellings on residential Blocks 7to 17 and 31. The OLA’s are in the form of raised (second floor) decks, which are less than 4 min depth. In accordance with the MOE noise guideline these areas are not considered OLA’s forthe purposes of the noise assessment and do not require noise mitigation.
2.4.4 Warning Clauses
Where the sound exposure guidelines are exceeded, appropriate warning clauses arerecommended to make future occupants aware of the potential noise situation.
See Table 3 and attached notes.
2.4.5 Commercial Blocks
The northern and eastern commercial blocks have the potential to create adverse impacts on theproposed residential portion. These commercial uses must be designed to meet the noise controlrequirements of NPC-300. A review of the potential noise impacts by the future commercial usesand associated rooftop HVAC systems should be made a condition of site plan approval for theseblocks.
3.0 INDUSTRY NOISE
The potential noise impacts from the two industrial plants at the east side of Peru Road werereviewed in great detail as part of our Reference 2 November 2006 Report (Modatek Systems atthe north, and Karmax Heavy Stamping at the south). The industrial noise assessment was basedon sound measurements made on these two industrial properties, including at the rooftop and withthe full cooperation of both plant operators.
3.1 INDUSTRY NOISE SOURCES
3.1.1 Modatek and Karmax Plants
The current analysis is based on updated information for the Modatek and Karmax plants, asdescribed in Appendices D and E, and the materials noted in Reference 9 to 12 as provided by

Magna International Inc.
Appendix D includes brief descriptions of the regular operations at the Modatek and Karmax plants,as provided to us with the Reference 9 materials. Appendix E describes the modelling parametersused in the assessment, which were provided by the acoustical consultants for the Town of Milton,Granite Real Estate Inc. and Magna International Inc.
3.1.2 Additional Industrial Lands at the East Side of Peru Road
As requested by the Town, a hypothetical industrial use was considered on the lands at 77 and99 Peru Road. The analysis is as discussed in the Revised Report. The relevant section from theRevised Report is included as Appendix F.
3.2 ENVIRONMENTAL GUIDELINES
The applicable environmental noise guidelines for new residential developments are given in MOEPublication NPC-300 and are summarized in Appendix B.
3.2.1 Outdoors
The MOE guidelines set a (one-hour Leq) exclusion limit of 50 dBA, or the ambient due to road trafficnoise, if higher, during any hour of the daytime and evening (0700 to 2300 hours), for the soundexposure from a stationary source at any Outdoor Point of Reception in any area amenable for use. Balconies or terraces under 4 m in depth are not considered points of reception. This is also takento apply to small grade-level spaces, such as patios or decks although this is not explicitly statedin NPC-300. There are no sound level limits for outdoor points of reception at night.
3.2.2 Plane of a Window
The applicable sound level limit is expressed in terms of one-hour Leq (as opposed to 16-hour [day]and 8-hour [night] as is used for ground transportation sources). The MOE guidelines provideminimum sound level limits that are called “exclusion limits” for stationary sources. The applicablereceptor sound limits are the exclusion limits or the existing ambient sound exposure, whichever is higher. Stationary sources need not mitigate to below the exclusion limits, regardless of theambient. The exclusion limits for a Class 1 area are:
• Daytime and Evening (0700 to 2300 hours): 50 dBA (Leq 1);• Nighttime (2300 to 0700 hours): 45 dBA (Leq 1).
The same numerical guideline limits also apply to impulsive sources, based on the logarithmicmean impulse level (LLM) description.
Certain sources are subject to being penalized where the source character has a greater potentialto cause annoyance, and has been included here where appropriate.
3.2.3 Ambient Sound Levels
Minimum ambient sound levels, due to road traffic sources (Highway 401 and New TremaineRoad), were predicted at the proposed residential buildings as discussed in the Revised Report.The relevant Report Sections are included as Appendix G.

3.2.4 Applicable Guideline Limits
The predicted ambient sound exposures are greater than the minimum exclusion limits at a majorityof the site. This is due to exposure to the nearby roadways, either directly or by reflection. Theminimum nighttime predicted ambient sound exposure levels are shown on Figure 3.
3.2.5 Town of Milton Noise By-law
Section 5 of the Town of Milton Noise By-law 133-2012 specifically encompasses the noiseguidelines documented in MOE publication NPC- 205. (It is to be expected that the by-law will beupdated to refer to NPC-300.)
3.2.6 D-1 and D-6 Land Use Compatibility Guidelines
Discussions regarding the D-1 and D-6 guidelines are as indicated in the Revised Report and havebeen included here as Appendix H.
3.3 NOISE IMPACT ASSESSMENT
3.3.1 Method
The noise analysis was done using CadnaA V4.1 environmental acoustics modelling software. A3-D model of each industrial plant and the surrounding lands was developed using the proposeddraft plan and industrial building massing (as defined by recent aerial imagery from Google Earth).The site topography is based on the most recent grading plan. The noise modelling accounts forthe parameters as described in Appendix E. The acoustical modelling follows the procedures ofISO 9613 Part 2 (except where variations were adopted from recommendations by the consultantsworking for the Town, Magna and Granite as noted in Appendix E – we are not necessarily in fullagreement with these variations but used them nonetheless).
The sound level predictions were done using the building evaluation method in the CadnaAacoustic model. This method calculates sound levels on a grid of points over each facade at eachstorey of the building. The ambient sound exposures were also calculated in this way at eachbuilding in the model. Algorithms within the acoustic modelling program were then used to subtractthe applicable guideline limits from the predicted sound levels, to determine locations where soundlevel excesses may occur.
3.3.2 Noise Control Measures
The sound level predictions account for the future noise control measures to be included at bothindustrial plants and as identified in Tables 1A and 2A of the Reference 10 materials; updated forModatek in the most recent Noise Abatement Action Plan which is Schedule B of the Amendmentto Environmental Compliance Approval (ECA), issue date of July 17, 2012.
As mentioned in Section 1.4, it has been assumed that the construction of the commercial blockswill not occur until after the construction of the residential component. Although the buildings onthese commercial blocks will provide acoustical screening from the industry sources, they have notbeen accounted for in the modelling.

At-receptor mitigation measures have been accounted for in the design of the residential portionof the site. These measures are discussed in Section 1.3 above.
3.3.3 Sound Level Prediction Scenarios
Several source scenarios were presented by Magna as part of the Reference 8 to 10 materials. Thethree most significant (primary) source scenarios for the Century Grove site are:
• Impulse – Modatek Future Impulse Scenario 2A; • Impulse – Karmax Impulse Scenario; and• Non-Impulse – Hypothetical Industry Scenario (including cumulative impacts from Karmax,
Modatek and the Hypothetical Industry).
All source scenarios that were provided were assessed. However, the predicted sound exposuresin the scenarios other than those above are less than those predicted in these primary scenarios. That is, satisfying the primary scenarios will also satisfy the other scenarios. Thus, these otherscenarios have not been included in the discussion below, but have been assessed and confirmedto result in compliance with the applicable MOE noise guideline limits.
The Acoustic Assessment Report prepared for Modatek considered the impulse sounds due totrucks as infrequent. For the purposes of this assessment these impulse sounds have beenconsidered frequent. This distinction significantly affects the applicable sound limit; infrequenthaving a much higher limit under both NPC-205 and NPC-300. Under NPC 300, frequent meansnine or more impulses occurring in the scenario hour. See Appendix E.
3.3.4 Sound Level Prediction Results
3.3.4.1 Modatek Impulse Scenario
The maximum predicted sound exposure results for the Modatek Impulse Future 2A Scenario areshown on Figure 4. Figure 5 shows the predicted sound level excesses; i.e., the predicted soundlevels with the applicable guideline limits subtracted (negative numbers are shown as zeros). Ascan be seen, the sound exposures are predicted to be below and in compliance with the applicableguideline limits and no sound level excesses are predicted on the development site.
3.3.4.2 Karmax Impulse Scenario
The maximum predicted sound exposure results for the Karmax Impulse Scenario are shown onFigure 6. Figure 7 shows the predicted sound level excesses. As can be seen, the soundexposures are predicted to be below and in compliance with the applicable guideline limits and nosound level excesses are predicted on the development site.
3.3.4.3 Non-Impulse Scenario
The maximum predicted sound exposure results for the non-impulse “Hypothetical IndustryScenario” are shown on Figure 8. Figure 9 shows the predicted sound level excesses. As can beseen, the sound exposures are predicted to be below and in compliance with the applicableguideline limits and no sound level excesses are predicted on the development site.

VALCOUSTICS CANADA LTD. Milton Heights Neighbourhood/Century Grove Parcel – Noise Feasibility/Update File: 102-286-300 Page 11
Ground vibration from stamping presses at Karmax is not anticipated to exceed the applicable limitsat the subject site. The subject site is well over 75 m from the CPR rail line and thus, a vibrationassessment is not required. Ground vibration is not anticipated to be problematic. See Appendix Ifor details of the press vibration analysis for Karmax.
5.0 CONCLUSIONS
The proposed development is considered to be feasible and appropriate, because compliance withthe applicable noise guidelines can be demonstrated provided some at-receptor mitigation isimplemented.
In summary:
1. Upgraded exterior wall construction is anticipated to be required for the dwellings closestto New Tremaine Road.
2. Upgraded windows should not be necessary for any residential lots/blocks.
3. Mandatory air conditioning is required for the dwellings closest to New Tremaine Road.
4. Beyond the first row requiring mandatory air conditioning, several rows will require theprovision to allow the future installation of air conditioning, by the occupant. Central airconditioning is recommended for the lots/blocks along the north side and the east, due toexposure to Highway 401 and also their proximity to the industrial uses, to help ensuregreater compatibility.
5. Sound barriers are required for the single family dwellings on Lots 1 to 5.
6. Warning clauses advising the occupants of the potential noise from the roadway or existing industries are required or recommended.
7. A detailed noise impact study will be required once final site grading and dwelling sitingsbecome available.
8. At-receptor mitigation measures have been included in the design of the site to mitigate thenoise impacts from the two Magna facilities. These measures are described in Section 1.3.
9. The analysis of the stationary source noise impacts has been updated based on the revisedmodelling parameters (as provided by others) and the current site and grading plans.
10. The updated Industry noise assessment shows compliance with the applicable MOE noiseguideline limits at all locations on the subject site.
11. Residential Blocks 9 to 14 form part of the mitigation for the stationary noise sourcesrelative to other residential blocks. Thus, these townhouse blocks will need to beconstructed prior to the remainder of the residential portion of the site, this includes thesingle family dwellings on Lots 1 to 5.

NOTES TO TABLE 3
1. Central air conditioning allows windows to remain closed for noise control purposes. Provision foradding air conditioning typically takes the form of a ducted ventilation system sized to accommodatethe addition of central air conditioning by the occupant.
2. The STC 54 requirement can be satisfied using brick veneer exterior wall construction. The STC 37requirement would be expected to be met with construction meeting the minimum non-acousticalrequirements of the Ontario Building Code.
3. The STC 31 requirement is expected to be met using construction meeting the minimumnon-acoustical requirements of the Ontario Building Code. A sliding glass walkout door should beconsidered as a window and be included in the percentage of glazing.
4. Earth berms, acoustic fences or combinations of berms and fences may be used, provided a minimumface density of at least 20 kg/m² is maintained, and the barrier is free of cracks, gaps and openings.
5. Standard example warning clauses to be registered on title and be included in Offers of Purchase andSale and Leases on designated units:
A. “Purchasers are advised that despite the inclusion of noise control features in thisdevelopment and within the building units, sound levels from increasing road traffic mayoccasionally interfere with some activities of the dwelling occupants as the sound level mayexceed the noise guidelines of the Municipality and the Ministry of the Environment.”
B. “Purchasers are advised that sounds from the area industrial uses may occasionally beaudible”.
C. “This dwelling unit has been supplied with a central air conditioning system which will allowwindows and exterior doors to remain closed, thereby ensuring that the indoor sound levelsare within the Municipality’s and the Ministry of the Environment’s noise criteria.”
D. “This dwelling unit has been fitted with a forced air heating system and the ducting, etc. wassized to accommodate central air conditioning. Installation of central air conditioning by theoccupant will allow windows and exterior doors to remain closed, thereby ensuring that theindoor sound levels are within the Municipality’s and the Ministry of Environment’s noisecriteria.”
6. Conventional roof construction meeting Ontario Building Code requirements is satisfactory in allcases.
7. All exterior doors shall be fully weatherstripped.

The analysis parameters and assumptions used in the assessment were:
• The source reference information as provided in the updated Tables 1A and 2A ofReference 9, except as noted.
• Building outline locations have been assumed based on “freehand” outlines per the currentaerial images on Google Earth.
• Sound power levels for all rooftop sources are assumed to have been generated assuminghemispherical radiation.
• Sound power level for the scrap metal bin is assumed to have been generated assuminghemispherical radiation.
• Based on our observations, we have noted some discrepancies with some of the sourceheights above roof as provided, namely the scrubber stacks as well as the cooling towers. Our modelling is based on the following source heights: Cooling Towers (Modatek) — fan3 m above the roof and no change to the 1.0 m source height for cooling tower casing.
• Source Name / ID MAU03/MOD_EX_M3_2 (RWDI ID M3-2) reference sound level wasadjusted from the 97 dBA to 79 dBA. The 97 dBA reference has been confirmed as a typoin the RWDI update data set provided to us.
• The default standard environmental conditions in the CadnaA model of 10EC and 70%relative humidity have been used.
• Order of reflections = 1 (pertains to the sound reflection characteristics from stationaryobjects in the Cadna/A model). Note, previous models and reports completed after 2006account for two orders of reflections. However, when second order reflections are used,several reflected paths from the interior buildings in the site are accounted for that are notnecessarily true sound reflection paths. This is because the CadnaA prediction model doesnot accurately account for reflected sound waves diffracted over barriers/buildings, as aproper ray tracing algorithm is not part of the software. The program predicts reflectionsaccounting for no screening objects and then applies a screening (or barrier) adjustmentafter the fact. These paths are not the diffracted paths over the buildings, and therefore donot represent a true reflection, or true summation of the reflected sound energy at a pointof reception.
CHANGES TO STATIONARY SOURCE ASSESSMENT FROM THE REVISED REPORT
As requested by RWDI (Magna International Inc.’s acoustical consultant), Jade Acoustics (GraniteReal Estate Inc.’s acoustical consultant) and Novus Environmental (The Town of Milton’s acousticalconsultant) certain changes to the analysis parameters, source sound levels and scenarios havebeen made.

General Modelling Parameters
The RWDI acoustic models referred to are understood to be those used for Ministry of theEnvironment (MOE) Environmental Compliance Approval (ECA) purposes for the respectiveindustries.
General changes to the modelling parameters are summarized below:
• It is understood that the RWDI acoustic model for Modatek uses a general groundabsorption factor of 0.9, with reflective areas around the Modatek Plant modelled using aground absorption factor of 0.2. The RWDI Karmax assessment was done using differentground attenuation factors, but RWDI recommends the Modatek ground settings be usedfor both plants. Our acoustic model has been updated using a ground factor of 0.2 for theindustrial lands. However, for the other areas (non-industrial land), hard ground surfaces(such as storm ponds and roads) were modelled with a ground absorption factor of 0.0 andlandscaped areas were modelled with a ground factor of 1.0. This was done since there willbe significantly more hard ground surface areas with the construction of the proposed MiltonHeights Neighbourhood, and a general ground term of 0.9 would not be consideredappropriate. Also, the ground attenuation factors used are more consistent with the ISOprediction standard, ISO 9613-2 “Acoustics - Attenuation of Sound During PropagationOutdoors”. Further, the settings used produce higher sound exposures at the proposedresidential areas, which is conservative.
• The following settings have been used in the CadnaA acoustic modelling software:
< “Exclude Ground Attenuation Over Barrier”;< “No Subtraction of Negative Ground Attenuation”; and< The box “No Negative Path Length Difference” has been checked, as has been the
case for all prior modelling.
Modatek Systems
• The Modatek yard impulse source levels used are those provided by RWDI.
• All at-source mitigation measures have been updated to reflect what is shown in the currentNoise Abatement Action Plan, which is Schedule B of the Amendment to ECA, issue dateof July 17, 2012.
• Modatek Impulse Scenario 2B, which includes impulses from the future operations at therail spur lines has been added back into the acoustic model. This scenario had beenremoved from the more recent modelling and reporting since it had been shown to beinsignificant and inconsequential to the conclusions, and to minimize the results scenariocontent.
Karmax
• The Karmax truck impulse source levels and assessment scenario used are those providedby RWDI.

VALCOUSTICS CANADA LTD. Milton Heights Neighbourhood/Century Grove Parcel – Noise FeasibilityFile: 102-286-300
• Four earthen berms on the Karmax property have been added to the model. Geographicalinformation (including height, location, position and extent) was provided by RWDI. Theheight of the berms was adjusted to account for the difference in industry base grades weare currently using. The information provided to us by RWDI shows base grades for bothindustries as 209.5 m. However, the topographical mapping provided from the Region ofHalton (via Swallow Acoustical Consultants) indicates the Modatek site grade is about212.2 m +/-, and at the Karmax site about 211.0 m +/-. It is noted that the 211.0 m +/-Karmax site base grade occurs at only a small section at the periphery, but inferring fromthat, the grade would not appear to be at 209.5 m as best as can be determined. Ouranalyses are based on the 212.2 m and 211.0 m base grades as noted above. The heightsof the berms provided by RWDI had to be adjusted accordingly. The change in elevationfrom 209.5 to 211 m results in a 1.5 m height difference. The grading as noted has beenused in the Valcoustics modelling in all prior cases.
General Note on Changes to Modelling Parameters
The source data and modelling parameters were provided by the other acoustical consultants onthe project. There are several parameters that we do not agree with:
• CadnaA software settings - the settings proposed are not in conformance with the standardbeing used to predict the outdoor sound propagation, ISO 9613-2 “Acoustics – Attenuationof Sound During Propagation Outdoors”.
• Modatek truck impulse scenario – it is understood that the reference sound level providedis based on sound measurements for only one type of activity which occurs in the yard, buthas been applied to all potential impulse sources (truck unloading/loading, forklifts drivingover bumps in the yard, etc.). The reference impulse sound level should be an impulseenergy average from all activities which occur, using a weighting to account for thefrequency of occurrence of the different events. In this way the analysis would berepresentative of the results that would be obtained if longer term sound monitoring wereto be done at a receptor.
• Modatek truck impulse scenario – it is further understood that the current AcousticAssessment Report (AAR) considers the impulse activity from the truck marshalling areato be an infrequent activity. (However, it is noted that the current AAR report has not beenmade available to confirm this). This results in a much higher sound level limit being usedat off-site points of reception. We are of the opinion that the assessment at the subject site,should be done the same as, and consistent with, the approach used for the AAR.
• Karmax truck impulse scenario – it is still not entirely clear how source levels were derived,and it appears the assessment method is not consistent with the method used for theModatek site. It would be expected that if the truck sources are the same at each site, thesource reference levels and assessment method should also be the same. The long-outstanding questions as to the source of the data remain unanswered.
• The non-impulse scenario considered includes the cumulative sum total of noise impactsfrom Karmax, Modatek and a third hypothetical industry at the subject site. This is not inconformance with the approach taken in the NPC-300 guidelines, where noise fromindustrial operations would be considered individually. It is expected this would have onlya minor effect on the report conclusion summarized herein.

• Regarding the hypothetical industry scenario assessment, NPC-300 indicates that a“planned and predictable mode of operation...” be assessed. As far as we are aware, thereis no planned industrial development to justify the assessment of the third hypotheticalindustry scenario. This analysis, as previously done, has been retained here, as originallyrequested by the Town of Milton.
Notwithstanding the issues mentioned above, the model has been updated using the sourcescenarios, sound level data and modelling parameters as provided.

3.1.1 Additional Industrial Lands at the East Side of Peru Road
The lands to the east located at 77 and 99 Peru Road are zoned for industrial use but are currentlyoccupied by existing residences. As requested by the peer reviewer retained by the Town of Milton,noise emissions from a future hypothetical industrial use have been considered for these lands. It is worthwhile noting that the existing heritage dwelling on the site is located closer to this newhypothetical industry than the new proposed residential portion of the subject site. Thus, the noiseemissions from any new industry to be developed on these lands would be limited by the presenceof this dwelling as well as the existing dwellings along Peru Road, where the noise guideline limitswould need to be met. In addition, the MOE guidelines require a planned predictable worst casebe assessed. As there are no plans to develop these lands for industrial uses, typically a fullassessment would not be done at this time. Regardless, a review was undertaken.
A use similar to the size and scope of the recently added warehouse at the Karmax lands has beenassumed on these lands. The assumed noise generating sources include:
• nine rooftop exhaust fans (same number and reference sound emission levels as theKarmax warehouse);
• one grade level emergency generator (same reference sound emission levels as theKarmax warehouse generator);
• two rooftop duct collectors (reference sound emissions based on measurements from otherVCL projects); and
• one rooftop cooling tower (reference sound level is based on the Modatek cooling towers,for a single unit).
5.2 Existing U-Need Storage Facility (75 Peru Road)
The site has been visited on several occasions, and negligible activity was observed, as well as ageneral absence of noise emissions at locations very close to the site. The potential noise sourcesonly appear to be that due to truck arrivals and departures, which seems minimal based on the siteobservations, as well as aerial imagery showing what appears to be a small operation.
The presence of several residential dwellings in much closer proximity to this the 75 Peru Road siterelative to the subject site, is noted, including dwellings at the west side of Peru, and not on theindustrial zoned lands as is the case for the land immediately north that includes a residentialdwelling within metres of the 75 Peru Road operations. The presence of the existing dwellings andthe obligation by the operator of 75 Peru Road to comply with the environmental noise requirementsis sufficient to ensure there will be no adverse impacts at the subject site.

3.2.3 Ambient Sound Levels
Minimum ambient sound levels, due to road traffic sources (Highway 401 and New TremaineRoad), were predicted at the proposed residential buildings. The road traffic predictions werecompleted using the CadnaA implementation of the RLS-90 traffic noise model. The RLS-90 modelwas “calibrated” using emission data for each road source as predicted by the MOE traffic noisemodel ORNAMENT/STAMSON.
The RLS-90 sound level predictions corelate well with the ORNAMENT/STAMSON sound levelpredictions over soft ground only. Over hard groung conditions, RLS-90 significantly under predictsthe sound exposures compared to ORNAMENT/STAMSON. A large portion of the ground betweenthe site and Highway 401 is hard (i.e., all paved surfaces, roads, existing and proposed parkingareas and the majority of the Magna industrial sites). The ambient sound level predictions weredone in part to account for these hard ground conditions.
The reference sound level from ORNAMENT/STAMSON is provided at 15 m. This reference soundlevel was adjusted for use in the RLS-90 algorithms, which use a 25 m reference distance. Thereference sound level adjustment was done in STAMSON accounting for hard ground.
With the adjustment done in this manner, the RLS-90 sound level predictions are much lower thanthe sound level predictions done through ORNAMENT/STAMSON over hard ground. This isconservative, giving lower ambient sound levels and hence lower guideline limits, at some areas.
All ambient calculations were completed for the most stringent nighttime period only, addressingthe worst case condition. For Highway 401, hourly road traffic data was provided by the MTO. Theaverage minimum hourly volume (over 7 days) for Highway 401 of 695 vehicles occurs during the0200 to 0300 hour. For New Tremaine Road, the future Year 2031 data provided by the Regionwas scaled back to the Year 2015 data using an assumed 2% annual decay rate (i.e., the reverseof a standard 2% annual growth rate). This was in the absence of near term estimates of the trafficvolumes on New Tremaine Road when initially opened, and coinciding with the initial occupanciesof the subject site. The minimum hourly data for New Tremaine Road was derived from the24-hour data using the typical ITE traffic distribution model for well travelled roadways. Accordingto this distribution, the minimum hourly volume of 44, which is 0.2% of the 2015 volume of 21,802vehicles, occurs during the nighttime hours of 0400 to 0500.
It is noted that the contribution of New Tremaine Road is only relevant at the west side of theCentury Grove site, at closest dwellings. At all other locations the sound level contribution fromNew Tremaine road is insignificant.

3.2.5 D-1 and D-6 Land Use Compatibility Guidelines
The MOE D-1 and D-6 guidelines are intended to assist in the planning process when new sensitiveland uses are proposed within the potential influence area of existing facilities, or when newfacilities are proposed where existing sensitive uses would be within the new influence area. Thestated objectives of the MOE guidelines are to "...minimize or prevent, through the use of buffers,the exposure of any person... to adverse effects associated with the operation of specifiedfacilities...". Environmental noise is one identified, potential, adverse effect.
Separation distance is one buffering technique. Other types of buffers or mitigation are recognized,such as sound barrier berms, walls or buildings. Where a specific site is proposed for development,it is the proponent's responsibility to investigate, propose and implement mitigation that can belocated either at the source, elsewhere on the facility site, on the sensitive land use site, or onintervening sites.
The D-6 guideline is a direct application of D-1, specific to industrial operations/facilities andsensitive land uses.
Guideline D-6 identifies potential separation distances between sensitive land uses and industry,based on categorizing industry into one of three classes.
Class I: potential zone of influence 70 m; minimum 20 m. Class II: potential zone of influence 300 m; minimum 70 m.Class III: potential zone of influence 1000 m; minimum 300 m.
The setbacks are typically lot line to lot line. Where zoning setbacks preclude uses with potentialfor conflict, setbacks on source or receptor properties can be part of the minimum setback.
In general, compliance with the numeric sound level guideline limits outlined in MOE publicationsLU-131 or NPC 205/232 (and now NPC-300) have been adequate to demonstrate land usecompatibility between industrial facilities and noise sensitive uses, for buffer setbacks less than thesuggested minimums outlined in the D-1 and D-6 publications.
There are several pit-falls in the literal application of Guideline D-6:
1. It is not always easy to fit every industry into only one of three categories. Some smallerindustries (Class I) sometimes have one of the characteristics of a larger industry (Class III)and as a result, on occasion, there has been a tendency to classify based on the highestcategory for any characteristic rather than on an overall judgement. This can lead toridiculous conclusions on occasion for very small industrial operations with onecharacteristic being the same as the Class III industry examples given in D-6.
2. Applying the minimum recommended (or other arbitrary) separation distance provides noassurance that there will be no environmental noise impacts and that no mitigation will berequired. There have been occasions where planners assumed that implementing eitherthe minimum or a separation distance equal to the indicated potential zone of influenceautomatically resolved all issues. Conversely, there are examples where noise sensitivedevelopments have been approved with buffer setbacks much less than the minimumsunder D-6, on the basis that the applicable MOE noise guideline limits of LU-131 or NPC205/232 (now NPC-300) are met. In fact, high density residential with common property

VALCOUSTICS CANADA LTD. Milton Heights Neighbourhood/Century Grove Parcel – Noise FeasibilityFile: 102-286-300
lines to Class III industry (i.e., 0 m setback) has been approved on this basis. In otherwords, compliance with the numeric sound level limits of the MOE can be a better predictorof land use compatibility, rather than buffer setbacks alone and in the absence of numericsound limits.
3. The D-1 and D-6 guidelines are broad guidelines considering a variety of potentialenvironmental impacts, including noise and air quality, etc. Distance separation alone isgenerally not an efficient mitigation technique for noise, because of the non-linearrelationship between sound level and distance from a source. That is, the rate of fall off ofsound level diminishes with increasing distance. Thus, relying on distance alone can leadto inefficient use of infrastructure and available land. Including mitigation such as soundbarriers, building orientation (e.g., direction that loading docks face), or noise control atsource (e.g., equipment selection, silencers on fans, etc.) can often lead to appropriatecompliance with noise criteria and land use compatibility, using separation distances lessthan the minimum in the D-6 guidelines.
5.0 APPLICATION OF D-1 AND D-6 GUIDELINES TO PROPOSED DRAFT PLAN
Both plants are automotive parts manufacturing and can be classified as Class II industries underD-6. The minimum setback is therefore 70 m. This classification is helped in part by thesubstantive planned or currently installed noise control measures in place and acoustical bufferingof many of the noise sources at both industries to address existing residential uses nearby. Further, the plants do not appear to be or have been a source of major annoyance for the existingcommunity, as evidenced by the general lack of documented noise complaints by the surroundingresidential uses. The minimum setback would therefore be 70 m on the basis of a Class II grading.
The draft plan shows an approximate 56 m wide drainage corridor (Block 40) adjacent to the 44 mwide commercial blocks (Blocks 36 and 37), adjacent to the residential portion along the east side. The separation between property lines of the closest residential and industrial lands (including forthe width of Peru Road and Street B) is about 142 m. This more than satisfies the 70 m Class IIminimum separation under D-6.
The minimum separation distance of 70 m, as recommended by D-6, is achieved in all cases.
On this basis, there is no need to further adjust the concept plan to resize the buffer setbackscurrently shown.

Excerpt from Reference 6 (November 28, 2006 Report by Valcoustics Canada Ltd.)
2.4 GROUND VIBRATION ASSESSMENT
Ground vibration due to the stamping presses at the Karmax plant were measured at severaloutdoor locations close to the press area at the southeast corner of the plant. The measurementswere made on July 13, 2004 and Karmax staff confirmed this area was operating normally duringthe measurements, including the largest presses. Ground vibration was clearly evident at outdoorareas close to the press locations.
The ground vibration assessment was considered in two ways:
1. the ground vibration was extrapolated to the closest proposed residential area immediatelyto the west, assuming the presses remain at the current location; and
2. Karmax has indicated the new warehouse at the west side could potentially be used forproduction at some future time, including stamping presses. To address this possibility, theground vibration measured at the current location was assumed to originate at the newwarehouse, and the results were extrapolated from this new location to the closestproposed residential area immediately to the west. The closest future press has beenassumed to be at the closest possible distance to the site, which is the extreme northwestcorner of the warehouse building. The setback to the closest proposed residential is about145 m, allowing for the press to be within 5 m of the exterior wall.
In either case, the extrapolation is based on the measured peak particle velocity level of0.36 mm/sec at 50 m from the west facade of the south-eastern press annex. This was the highestvibration level measured at the furthest distance from the presses and provides the worst casecondition for the extrapolations. The results will vary slightly based on the assumptions used inregard to the reference distance to the vibration source. Our analysis considered the closestbuilding facade as well as the centre of the press room annex as the reference distance for themeasured vibration levels. These two reference distances were considered since multiple presseswere in operation, and it is not known which press created the highest vibration level. The groundattenuation as a function of distance is based on the methods of Reference 7.
Based on the current location, a ground vibration level of 0.006 to 0.013 mm/sec is predicted at theclosest proposed residential areas, which is well below the reference MOE 0.3 mm/sec guideline.
Assuming the ground vibration originates from the closest part of the warehouse building at thewest, a ground vibration level of 0.07 to 0.16 mm/sec is predicted at the at the closest residentialarea, which also is well below the reference 0.3 mm/sec criteria.
The results show that ground vibration from the stamping presses will be well below the referencevibration guidelines based on the measurements made and assuming the same installationmethods for the new presses.

2. Analysis
Two methods were used for the vibration level prediction when determining the vibrationlevel at the closest proposed residential property and assuming that presses couldpotentially be located in the new warehouse at the west side of the Karmax property. Method #1 assumes the measured vibration level at 50 m from the west face of the existingpress annex ( ) originated from the centre of the press annex building (i.eV mm sref = 0 36. /reference distance approximately 84 m). Method #2 assumes the measured vibration leveloriginated very close to west face the press annex building (i.e. reference distanceapproximately 50 m).

2.1 Method #1
Using the measurement at 50 m opposite the west face of the existing press annex,assume the source of the vibration originated at the centre of the existing building (pressannex building at the extreme southeast). The closest proposed residential property lineis approximately 145 m from the west face of the new warehouse building. Therefore,
