SUMMARY

The proposed residential development is located east of the GO Transit/Metrolinx rail corridor

between Shore Acres Drive and Gilford Road in the Town of Innisfil, County of Simcoe. The

site is subject to noise from rail traffic on the GO line and road traffic on Shore Acres Drive.

The site is not affected by commercial, industrial or aircraft noise sources.

The environmental noise guidelines for transportation sources of the Ministry of the

Environment, Conservation and Parks (MOE) set out sound level limits for both indoor and

outdoor space. Sound levels due to road and rail traffic were determined using ORNAMENT,

the noise prediction model of the MOE for road traffic and STEAM, the noise prediction model

of the MOE for rail traffic. For stationary sources, the MOE guidelines were used. GO Transit

has adopted the CN noise and vibration guidelines which apply to residential developments

adjacent to their right-of-ways (R.O.W).

Using the road and rail traffic data obtained from the Town of Innisfil, NexTrans Consulting,

and Metrolinx, the sound levels for various locations within the residential development were

determined.

It was found that with appropriate mitigative measures, all residential lots in the development

will meet the noise guidelines.

Lots 1 to 12 and 23 in proximity of Shore Acres Drive and the GO Transit/Metrolinx R.O.W.

require forced air heating systems sized to accommodate central air conditioning at a later date

if noise becomes a concern. Table 3 and Figure 2 show the ventilation requirements.

The proposed development is in proximity to the GO Transit/Metrolinx right-of-way (R.O.W.).

Future occupants should be advised of the proximity to the rail line in the form of a warning

clause.

Based on the preliminary analysis, no special window, exterior door and exterior wall

construction above typical building practices will be necessary for any of the proposed lots.

Due to a separation distance of approximately 200 m, railway groundborne vibration will be

insignificant at the proposed residential lots; therefore, vibration mitigation measures are not

required.

Once grading plans are prepared, detailed noise studies should be undertaken to confirm our

preliminary findings and ensure that the applicable guidelines are met.

1.0 INTRODUCTION

Jade Acoustics Inc. was retained to prepare an update to the

Preliminary Environmental Noise Report prepared by Jade Acoustics Inc. dated May 3, 2017,

to investigate the updated draft plan and the potential impact of noise and rail groundbourne

vibration on the proposed development to the satisfaction of the Town of Innisfil,

County of Simcoe and GO Transit/Metrolinx.

The site is identified as:

Lots 21 and 22

Concession 15

Town of Innisfil

County of Simcoe

The site is located at 0 Shore Acres Drive and is bound by Shore Acres Drive to the north, an

existing golf and country club and residential development to the north of Shore Acres Drive,

existing residential to the south and east, and the GO Transit/Metrolinx rail corridor to the west.

The analysis was based on the following:

Site visit conducted by Jade Acoustics Inc. staff on July 30, 2019;

Updated Draft Plan prepared by Weston Consulting dated September 12, 2019;

Grading plans provided by A.M. Candaras Associates Inc. on July 27, 2019;

Road traffic information provided by the Town of Innisfil on November 30, 2016;

A preliminary traffic study prepared by NexTrans Consulting dated August, 2019 and

provided on August 22, 2019; and

Rail traffic information provided by Metrolinx on August 9, 2019.

A Key Plan is attached as Figure 1. Figure 2 shows the proposed development.

The proposed development is comprised of 35 residential lots (detached dwellings),

environmental protected lands, and a new internal road.

All dwellings are expected to be two storeys.

2.0 NOISE AND VIBRATION SOURCES

2.1 Transportation Sources

The primary noise sources with the potential to impact the project are the rail traffic on the

adjacent GO Transit/Metrolinx rail corridor and road traffic on Shore Acres Drive.

The site is not affected by aircraft traffic.

2.1.1 Road Sources

The proposed development is subject to road traffic noise from Shore Acres Drive.

The existing road traffic information (speed and R.O.W.) for Shore Acres Drive was provided

by the Town of Innisfil on November 30, 2016.

A Preliminary Transportation Impact Study dated August, 2019, was prepared by

NexTrans Consulting for this proposed development. The study outlines the traffic impact of

the proposed development on existing and new roadways. The future AM/PM peak hour traffic

volumes were provided for Shore Acres Drive, 20th Sideroad, and the new internal street “A” as

part of the proposed development. Based on the peak hour volumes (for Year 2024), the

average daily traffic on 20th Sideroad and Shore Acres Drive was calculated in both cases

accounting for the peak hour to be 10% of the average daily traffic. Furthermore, the AADT

was escalated to 2029 at a growth rate of 2%. The growth rate and 10% factor noted above

were verified as being applicable with NexTrans Consulting.

Due primarily to the separation distance and screening by intervening residential dwellings,

road traffic on Gilford Road and 20th Sideroad was calculated to be acoustically insignificant;

therefore, these two roads were not considered further in the report.

The truck percentage information for Shore Acres Drive was based on the

Transportation Impact Study prepared by NexTrans Consulting dated November, 2016.

The road traffic information provided by NexTrans Consulting and the Town of Innisfil are

found in Appendix A. A summary of the ultimate road traffic information is included in Table 1.

2.1.2 Rail Sources

The GO Transit/Metrolinx corridor (principal main line) is located west of the proposed

development, with intervening environmental protected lands between the railway and the

proposed residential lots.

0 Shore Acres Drive

The passenger rail traffic data for the ultimate time frame was provided by

GO Transit/Metrolinx. CN has indicated that there is no freight rail traffic on this line.

The rail data used in this report is summarized in Table 1 and correspondence excerpts can be

found in Appendix A.

The Shore Acres Drive and Gilford Road crossings are crossings in which the train whistle is

sounded. Therefore, whistle noise was included in the analysis of the architectural

requirements.

Due to a separation distance of approximately 200 m, railway groundbourne vibration will be

insignificant at the proposed residential lots; therefore, railway vibration was not considered

further in the report.

3.0 ENVIRONMENTAL NOISE AND VIBRATION CRITERIA

The environmental noise criteria used for residential developments in the Town of Innisfil,

County of Simcoe and the MOE environmental noise criteria are contained in Appendix B and

summarized below.

The most recent environmental noise guidelines (NPC-300) of the Ontario Ministry of the

Environment, Conservation and Parks (MOE) were used for this report.

The MOE document “Environmental Noise Guideline Stationary and Transportation

Sources – Approval and Planning, Publication NPC-300”, dated August, 2013, released

October 21, 2013 (updated final version # 22) was used for the analysis. A brief summary of

the NPC-300 guidelines is given in Appendix B. The guidelines are also summarized below.


3.1.1 Indoors

If the nighttime (11:00 p.m. to 7:00 a.m.) sound level in terms of Leq at the exterior face of a

bedroom or living/dining room window is greater than 60 dBA and/or if the daytime

(7:00 a.m. to 11:00 p.m.) sound level in terms of Leq at the exterior face of a bedroom or

living/dining room window is greater than 65 dBA, means must be provided so that windows

can be kept closed for noise control purposes and central air conditioning is required. For

nighttime sound levels (LeqNight) greater than 50 dBA to less than or equal to 60 dBA on

the exterior face of a bedroom or living/dining room window or daytime sound levels

(LeqDay) greater than 55 dBA to less than or equal to 65 dBA on the exterior face of a

bedroom or living/dining room window, there need only be the provision for adding central air

conditioning by the occupant at a later date. This typically involves a ducted heating system

sized to accommodate the addition of central air conditioning by the occupant at a later date.

A warning clause advising the occupant of the potential interference with some activities is

also required.

In all cases, air cooled condenser units must not exceed an AHRI sound rating of 7.6 bels.

The air cooled condenser units must be sited in accordance with the zoning by-laws with

respect to setbacks as well as location.

As required by the MOE, indoor noise criteria for road traffic noise is 40 dBA (Leq8hour) for the

bedrooms during nighttime hours, 45 dBA (Leq8hour) for living/dining rooms during nighttime

hours and 45 dBA (Leq16hour) for the living/dining rooms and bedrooms during daytime hours.

These criteria are used to determine the architectural requirements.

0 Shore Acres Drive

Jade Acoustics Inc.

In addition, the MOE guidelines for rail noise are 5 dB more stringent to account for tonality of

rail noise. The indoor noise criteria for rail traffic are 35 dBA (Leq8hour) for the bedrooms

during nighttime hours, 40 dBA (Leq8hour) for living/dining rooms during nighttime hours and

40 dBA (Leq16hours) for living/dining rooms and bedrooms during daytime hours. These

criteria are used to determine the architectural requirements.

3.1.2 Outdoors

For the outdoor amenity areas, a design goal of 55 dBA for the daytime period between

7:00 a.m. to 11:00 p.m. is used for road and rail traffic. In some cases an excess not

exceeding 5 dBA is considered acceptable. Where the unmitigated sound levels during the

day exceed 55 dBA (Leq16hour, daytime) but are equal to or less than 60 dBA (Leq16hour,

daytime), a warning clause is required and mitigation should be considered as per the MOE

guidelines. Where the unmitigated sound levels exceed 60 dBA, mitigation measures and a

warning clause are required.

The Town of Innisfil requires that every effort be made to achieve 55 dBA in the outdoor

amenity areas.

For both indoor and outdoor conditions, where the acoustic criteria are exceeded, warning

clauses must be placed in offers of purchase and sale or lease agreements and included in the

development agreement.

3.1.3 GO Transit/Metrolinx

GO Transit/Metrolinx has noise and vibration guidelines which apply to residential

developments adjacent to their R.O.W. In general, the railway guidelines follow the MOE

guidelines for the indoor and outdoor sound level limits. Whistle noise (where applicable)

should be included in the determination of the acoustical performance of the building

components; however, whistle noise is not included in the outdoor amenity area calculations or

for the determination of air conditioning requirements.

In addition, the railways require that for a principal main line:

A minimum setback of 30 m from the right-of-way be maintained;

A safety berm/sound barrier of minimum 5.5 m in height (2.5 m high berm

and 3.0 m high acoustic fence) typically measured with respect to the

top-of-rail elevation or a plane joining the top of rail and the ground at the

nearest wall of a residential building be constructed along the rail

right-of-way;

0 Shore Acres Drive

Jade Acoustics Inc.

7

Regardless of whether the noise level exceeds the 60 dBA level set by

MOE, as a minimum, brick veneer or equivalent masonry exterior wall

construction for the first row of dwellings facing the railway right-of-way;

Vibration mitigation be incorporated in the building design for all residential

units within 75 m of the right-of-way or alternatively on-site vibration

measurements be conducted to determine if an excess exists; and

All residential units within 300 m of the right-of-way have a warning clause

placed in offers of purchase and sale, in lease agreements and a

registerable portion of the subdivision agreement, making future residents

aware of the existence of the railway.

See Appendix B for a summary of the applicable noise and vibration guidelines.

3.2 Railway Vibration

GO Transit/Metrolinx has vibration guidelines which apply to near residential developments

adjacent to railway lines. These guidelines state that for any residential dwellings within 75 m

of the railway right-of-way, an overall vibration velocity limit of 0.14 mm/s between 4 Hz and

200 Hz is applicable. These guidelines have been used in the report.

3.3 Stationary Sources

MOE Noise Guidelines

The guidelines of the Ontario Ministry of the Environment, Conservation and Parks (MOE) for

stationary sources are to be used for the commercial/industrial facilities.

The MOE has recently published the document NPC-300 titled “Environmental Noise Guideline

Stationary and Transportation Sources – Approval and Planning”.

The MOE also has vibration guidelines with respect to stationary sources, NPC-207. These

guidelines require that the peak vibration velocities not exceed 0.3 mm/s at the point of

reception during the day or night.

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 do not require that the source be inaudible, but

rather that specific sound level limits be achieved.

0 Shore Acres Drive

Jade Acoustics Inc.

8

With respect to stationary sources of noise in urban areas, the MOE guidelines require that the

sound level due to the stationary source at the building façade and outdoor amenity spaces not

exceed the sound level due to road traffic and in certain situations due to rail traffic in any hour

of source operation, subject to specific exclusions. Tables C-5, C-6, C-7 and C-8 of NPC-300

included in Appendix B provided the exclusion limit values of one-hour equivalent sound level

(Leq, dBA) and impulsive sound level (LLM, dBAI).

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. Treatment of the

receptor building by the use of suitable wall and window construction and central air

conditioning to keep windows closed is not an acceptable solution to the MOE in Class 1 and 2

areas (urban). In addition, a warning clause in offers of purchase and sale and/or lease

agreement noting the proximity of dwellings to such a source should be considered.

3.4 Town of Innisfil Noise Control By-law

The Town of Innisfil has a by-law to prohibit or regulate noise likely to disturb the inhabitants of

the Town; Noise Control By-law Number 122-16 dated December 14, 2016. The by-law does

not provide specific sound level limits but rather provide qualitative information with respect to

sources and provides prohibitians by time and place.

4.0 NOISE IMPACT ASSESSMENT


For road and rail traffic noise, the sound level in terms of Leq, the energy equivalent

continuous sound level for both day (Leq16) and night (Leq8) was determined using

the MOE Traffic Noise Prediction Models, ORNAMENT (road traffic) and STEAM (rail traffic).

Lot 12 has exposure to Shore Acres Drive and the unmitigated daytime sound level in the rear

yard is predicted to be 51 dBA. The sound level at the side wall (second storey) is predicted to

be 59 dBA (daytime) and 52 dBA (nighttime).

For Lot 1 with exposure to Shore Acres Drive and the GO Transit/Metrolinx rail line, the

daytime and nighttime sound levels at the second storey of the side wall are predicted to be

58 dBA and 53 dBA, respectively and including whistle noise.

Table 2 provides a summary of the predicted sound levels outdoors due to road and rail traffic

at specific locations (the lots listed above as well as others) without any mitigative measures.

Appendix C includes sample calculations.

Where the sound level limits are expected to exceed the noise guidelines, mitigative measures

and warning clauses are required.

5.0 NOISE ABATEMENT REQUIREMENTS


The noise mitigation requirements for both the indoor and outdoor locations are detailed below.

Table 3 and Figure 2 provide a summary of the noise control measures needed to meet the

noise control guidelines. In addition, when mitigation measures are required, warning clauses

are also required. A warning clause advising of the existence of the railway is required for all

lots within 300 m of the rail right-of-way. The suggested warning clauses are provided in the

Notes to Table 3.

5.1.1 Indoors

The MOE indoor sound level criteria for road traffic are 40 dBA for the bedrooms and 45 dBA

for the living/dining rooms during daytime and nighttime hours, as well as the bedrooms

during daytime hours. As required by the MOE and GO Transit/Metrolinx, the indoor criteria

for rail traffic is 5 dB more stringent. The characteristic spectrum for the noise sources has

been accounted for in the determination of the architectural components. Appendix D

contains a sample calculation of architectural component selection.

Since house plans are not yet available, the final architectural choices cannot be made.

Therefore, a preliminary analysis using assumed window and exterior wall percentages has

been conducted to provide an indication of the architectural requirements. Once house

plans are available, the architectural component requirements should be re-evaluated.

Calculations were performed for both a ground floor corner living/dining room and a second

storey corner bedroom. For the living/dining room, the exterior wall perpendicular to the

noise source and the wall parallel to the noise source were each assumed to be 55% of the

associated floor area. The windows located on the wall parallel to the noise source and the

wall perpendicular to the noise source were each assumed to be 25% of the associated floor

area. For the bedroom, the wall parallel to the rail line was assumed to be 55% of the floor

area and the wall perpendicular to the rail line was assumed to be 80% of the floor area.

The window was assumed on the wall parallel to the rail line and to be 25% of the associated

floor area. In calculating the sound levels for this analysis, rail whistle noise for the

crossings at Shore Acres Drive and Gilford Road was taken into account.

The worst case locations are lots exposed to Shore Acres Drive and the

GO Transit/Metrolinx railway having a corner living/dining room or corner bedroom. Based

on the ratios mentioned above, windows and exterior doors need to be up to STC 23 and

exterior walls need to be up to STC 34. An STC 23 rating for windows and exterior doors

and walls an STC 34 rating for exterior walls are satisfied by using window, exterior wall and

0 Shore Acres Drive

Jade Acoustics Inc.

11

exterior door construction which comply with the minimum structural and safety requirements

of standard construction.

An STC 54 rating for the roof, normally met by most residential roof construction with

ventilated attic space, would be acoustically acceptable.

In general, where the sound level on the exterior face of a bedroom window or living room

window is sufficiently high that the outdoor criteria are exceeded by more than 10 dBA,

ventilation provisions must be made to permit windows to remain closed. Based on the

predicted sound levels, no lots will require central air conditioning.

Where the outdoor criteria are exceeded by 1 dBA to 10 dBA, the provision for adding air

conditioning by the occupant must be made. This is required for Lot 16. See Table 3 and

Figure 2 for details.

Warning clauses will also be required to be placed in offers of purchase and sale or lease

agreements and in the development agreement for all relevant lots to make future occupants

aware of the potential noise situation.

All air cooled condenser units are not to exceed an AHRI sound rating of 7.6 bels. The air

cooled condenser units must be sited in accordance with municipal zoning by-laws with

respect to setbacks as well as location.

See Table 3 and Notes to Table 3 for details of minimum noise abatement measures

required. Warning clause requirements are listed in Table 3 and specific wording is included

in the Notes to Table 3.

5.1.2 Outdoors

For the outdoor amenity areas, the objective for road and rail traffic noise is a sound level of

55 dBA during the daytime (7:00 a.m. to 11:00 p.m.). Where the sound levels during the day

exceed 55 dBA, a warning clause is generally required and mitigation should be considered. If

the sound levels during the day are equal to or greater than 60 dBA, sound barriers and a

warning clause are warranted.

Based on the predicted sound levels, sound barriers are not required for any of the proposed

lots.

6.0 CONCLUSIONS

With the incorporation of the items discussed (see Table 3, Notes to Table 3 and Figure 2), thesound levels will be within the appropriate environmental noise criteria. ln accordance with

Town and Ministry implementation guidelines where mitigation is required, future occupants will

be advised through the use of warning clauses.

Prior to the issuance of building permits, the house plans should be reviewed by an acoustical

consultant to ensure compliance with the applicable guidelines.

Prior to final occupancy, the lots should be inspected by an acoustical consultant to ensure therequired mitigative measures have been incorporated.

NOTES TO TABLE 3

1. Provision for adding central air conditioning would involve a ducted heating system

sized to accommodate the addition of central air conditioning by the occupant at a later

date. The air cooled condenser unit AHRI sound rating must not exceed 7.6 bels and

should be placed in a noise insensitive location which complies with municipal by-laws.

2. STC – Sound Transmission Class Rating (Reference ASTM-E413). Results shown are

based on an assumed wall area of 55% of the associated floor area for the wall facing

the noise source and for the wall perpendicular to the noise source.

3. STC – Sound Transmission Class Rating (Reference ASTM-E413). Results shown are

based on an assumed glazed area of 25% of the associated floor area for the window

facing the noise source and for the window perpendicular to the noise source. A sliding

glass walkout door should be considered as a window and be included in the

percentage of glazing. Requirements are to be finalized once building plans are

available.

4. Sound barriers must be of solid construction with no gaps and have a minimum surface

density of 20 kg/m2. Earthen berms, solid walls/fences of adequate density or

combinations of berms and walls/fences may be used.

5. Suggested warning clauses to be included in the subdivision agreement and to be

included in offers of purchase and sale or lease agreements on designated lots:

A. “Purchasers/tenants are advised that despite the inclusion of noise control

features in this development area and within the dwelling units, noise due to increasing

road and/or rail traffic may continue to be of concern, occasionally interfering with the

activities of the occupants as the sound levels may exceed the noise criteria of the

Municipality and the Ministry of the Environment, Conservation and Parks. I, the

purchaser hereby agree to place this clause in all subsequent offers of purchase and

sale when I sell the property.”

B. “Purchasers/tenants are advised that this dwelling unit can be fitted with a

central air conditioning system at the owner’s option and expense which will enable

occupants to keep windows closed if road traffic noise interferes with the indoor

activities. If central air conditioning is installed, the air cooled condenser unit shall have

an AHRI sound rating not exceeding 7.6 bels and shall be located so as to have the

least possible noise impact on outdoor activities of the occupants and the neighbours.”

From: Rail Data Requests <[email protected]>Sent: August 9, 2019 9:40 AMTo: Kristofer TassisCc: Chris Kellar; Brandon GaffoorSubject: RE: re: Metrolinx rail data request - 0 Shore Acres Drive - Innisfil (Jade File: 16-120-01)

Good Morning Kristofer, Further to your request dated July 30, 2019, the subject site (0 Shore Acres Drive, Innisfil) is located immediately adjacent to Metrolinx’s Newmarket Subdivision, which carries Barrie GO Train service. It’s anticipated that GO service on this line will be comprised of electric trains within (at least) a 10-year time horizon. The combined preliminary midterm weekday train volume forecast at this location, including both revenue and equipment trips is in the order of 42 trains – (36 day, 6 night). Trains will be comprised of a single locomotive and up to 12 passenger cars. The track design speed at this location on this corridor is 70 mph (113 km/h). The Newmarket Subdivision is a Principle Mainline Track. Train whistles will sound at the Shore Acres Drive and Gilford Road at-grade crossing. With respect to future electrified rail service, Metrolinx is committed to finding the most sustainable solution for electrifying the GO and UP Express rail network and we are currently working towards the next phase. Metrolinx has not made a final decision regarding the electric train technology or technologies to be deployed. We can, however, provide the following interim information which may be helpful;

1. At lower speeds, train noise is dominated by the powertrain. At higher speeds, train noise is dominated by the wheel- track interaction. Hence, at higher speeds, the noise level and spectrum of electric trains is expected to be very similar, if not identical, to those of equivalent diesel trains.

2. Along with electrification, Metrolinx will intensify service levels along all of its corridors to deliver the promised GO Expansion service. Everything else being equal, this will likely result in an overall increase in train noise emissions.

Given the above considerations, it would be prudent, for the purposes of acoustical analyses, to assume that the acoustical characteristics of electrified and diesel trains are equivalent. In light of the aforementioned information, acoustical models should employ diesel train parameters as the basis for analyses. We anticipate that additional information regarding specific operational parameters for electrified trains will become available in the future. Operational information is subject to change and may be influenced by, among other factors, service planning priorities, operational considerations, funding availability, and passenger demand. It should be noted that Metrolinx does not maintain information in respect to corridor elevation, track gradient and alignment, and right-of-way width. It is up to the consultant to collect that information through corridor survey work. Requests to enter Metrolinx’s rail corridors can be sent to [email protected]. I trust this information is useful. Should you have any questions or concerns, please do not hesitate to contact me.

I kindly request the following information (existing and ultimate) with the day/night split for the rail operations on the GO Rail Line near the proposed residential development;

- Number of trains by type (passenger, freight, commuter, switcher, etc.); - Number of locomotives per train; - Number of cars per train; - Train speed; - Track gradient; - Elevation of tracks; - Whistle locations;

3

- Right-of-way width (R.O.W.); - Track alignment on R.O.W.; and - If no ultimate data is available, then annual percent increase and number of years of growth.

Please confirm the classification of this rail line, such as principal or secondary main line, or provincial branch line etc. I’ve attached a figure of the site for your convenience. Please reply at your earliest convenience. If there are any questions, please do not hesitate to call. Kris Tassis BASc, E.I.T.

Vibration

Groundborne vibration transmission to be estimated through site testing and evaluation to

determine if dwellings within 75 metres of the Railway R.O.W. will be impacted by vibration

conditions in excess of 0.14 mm/sec. RMS between 4 Hz and 200 Hz. The monitoring

system should be capable of measuring frequencies between 4 Hz and 200 Hz, + 3 dB with

an RMS averaging time constant of 1 second. If in excess, isolation measures will be

required to ensure living areas do not exceed 0.14 mm/sec RMS on and above the first floor

of the dwelling.
