DESIGN AND CONSTRUCTION

PLANNING REPORT

Demolish existing Service Station and Buildings To redevelop the land for a 24hour service station incorporating a carwash, associated carparking, variation to the crossover widths (existing crossovers) required by Clause 52.12 and internally illuminated advertising signage. Use Existing.

Property Address: 145a Percy Street Portland Date: February 2018

Applicant: SMB Design and Construction Owner: Darren Noseda 922-924 Raglan Parade Warrnambool


1 Site and Surrounds The subject site is located at 145a Percy Street Portland. The site is irregular in shape with a frontage of 62.91 metres to Percy Street. The site has an area of 2749 sqm. The site is currently used as a service station and car repair workshops. The land is zoned IN3Z and partly C2Z the property to the North of the site is zoned IN3Z. The property across Percy Street (RDZ1) is zoned C2Z. Properties to the South are zoned CZ1 and the properties two the West are zoned GRZ1.


2 Proposal The proposal is for buildings and works associated with the use of the land for the purpose of a Service Station/Convenience Store and Carwash.


Described as follows: SERVICE STATION/CONVENIENCE STORE/CARWASH The Service Station and carwash use will operate 24 hours a day, 7 days a week. No mechanical repairs are proposed to operate from this site. The Convenience Store Building is 120sqm and has a maximum height of 4.20m. The building is setback 8.5m from Percy Street property boundary which is less than the existing building (to be demolished) on the site and 0m on the Northern boundary. There is one public entry to the building on southern side fronting the fuel canopy. The fuelling canopy has an area of 485 sqm. The canopy will have a maximum height of 6.2 m providing weather protection to the petrol pump forecourt. The fuel pumps are located 4.8m from the property boundary. Proposed pumps, fuel refill points and underground fuel storage tanks are shown indicatively on the plans. The carwash building is 73sqm and is located 27.035 meters from the front property boundary, 0.15 meters for the southern boundary and 11.10m from the rear boundary. It has a maximum height of 6.0meters The plantroom is 18sqm and is located 6.15 meters from the front boundary and at its closest point 1.0 meters for the side boundary. It has a maximum height of 3.2 meters. A total of 11 car parking spaces (including one disabled space) are proposed to be located on the north and western side of the site. There is also an additional space provided for air and water. There are also 8 available spaces under the canopy. There is one loading bay on the eastern side of the building and measures 8.0m x 3.8mard area. Convenience store deliveries will occur between zero and 3 times daily. Fuel deliveries will be 2-3 times per week, 7am until 10pm via 19m semi trailer. The attached traffic report shows vehicle turning template and location of the indicative underground fuel filling points demonstrate that a 19m fuel tanker is located wholly on the site while filling the tanks and that all vehicles can enter, circulate and exit the site safely. Mechanical plant will be located either on the roof or adjacent to the building. Vehicle access to the site will be via the existing crossovers on Percy Street. The proposed crossovers will allow for both entry and exiting to and from the site The crossovers are in excess of the 7.7m requirement of Clause 52.12-1. A number of business identification signs are proposed for the site in the form of a non- illuminated and illuminated. See attached signage drawing for details and locations. 490 Sqm of landscaping is provided on the site see the accompanying site plan for details. The landscaping backing on to the Residential properties is 5.7m in width and is in excess of the requirement.


3 Planning Controls The subject site is included within the Industrial 3 zone (IN3Z) and Commercial 2 Zone (C2Z) and is not affected by any overlays pursuant to the provisions for the Glenelg Shire Council Planning Scheme. 3.0 Industrial Three and Commercial One Zone The Service Station/Convenience Store is located within the I3Z and is listed in the Permit Not Required section but the land is within 30m of a Residential Zone and therefore requires a permit The development is also subject to existing rights use. The Carwash is located in the CZ1 of the site and is not listed in any of the Sections and therefore requires a permit. A permit is required for construction of a building for both zones. The use of the development is compatible with the needs of the surrounding community and is existing for the service station/convenience store. The scale and intensity of the development is proportionate to the surrounding buildings. The site has adequate landscaping and provides softening of the development. There is adequate carparking on the site. The internal layout of the site provides safety for both traffic and pedestrians. It is noted that the IN3Z is included in the Category 2 and CZ1 is included in Category 1 for the purposes of the advertising sign requirements at Clause 52.05-7 of the Planning Scheme. 3.05 Particular Provisions In addition to the zone and overlay provisions of the Scheme, the following particular provisions are also relevant to the proposal. Clause 52.05 Advertising Signs – A permit is required under the provision for a business identification sign with a total area to the premises in excess of 8 sqm, internally illuminated business identification signs with an area in excess of 1.5sqm and internally illuminated major promotion business identification signs.

• The illuminated ID sign is 1.85sqm. Clause 52.06 Car Parking- 11 Car spaces are provided and therefore the car parking is consistent with the requirements of 52.06. Clause 52.07 Loading and Unloading of Vehicles: A Building with a floor area of 2,600 sqm or less in a single occupation and associated with the manufacture servicing, storage or sale of goods or materials required a loading bay with a minimum length of 7.6m and a width of 3.6 m, resulting in an area of 27.4 sqm. A permit may be granted to reduce or waive these requirements. The proposed loading bay adjoining the building is consistent with the loading bay requirements of Clause 52.07


Clause 52.12 Service Station – A permit is required to vary the requirements of this provision. A variation is sought from these requirements in relation to: Crossovers and Dimensions, Road Setbacks.

• The existing crossovers to the Percy Street are 10.2m and 13.8m in width and are therefore exceeding 7.7 metres.

• The building is site back 8.5m from the Percy Street frontage and therefore less that the 9.0m required in road setbacks.

Clause 52.13 Carwash- A permit is required to vary the requirements of this provision. A variation is sought from these requirements in relation to: Crossover widths and queuing lanes.

• The existing crossovers to the Percy Street are 10.2m and 13.8m in width and are therefore exceeding 7.7 metres.

• Refer to the attached Traffic Report for queueing. Clause 52.29 Land Adjacent to a Road Zone, Category 1, or a Public Acquisition Overlay for a Category 1 Road – A permit is required to alter access to a Road Zone Category 1 Under this provision, an application to alter access to land owned by the Roads Corporation for the purpose of a road must be referred to the Roads Corporation under Section 55 of the Act. It is noted that there are crossovers to Percy Street are existing and are not being altered. Clause 52.34 Bicycle Facilities – Table 1 to Clause 52.34-3 Requires the 1 space to each 600sqm of leasable floor area and 1 visitor/ shopper space to each 3500 sqm of leasable floor area. A permit may be granted to vary, reduce or waive any requirement of Clause 52.34-3 and Clause 52.34-4. A bicycle parking area is not required for this development.

5 Planning Assessment The use of the land for purposes of a Service Station/Convenience Store and carwash , aligns with policy guidance contained within the Planning Scheme. In this regard, the proposal is appropriately located on the site with frontages to Percy Street. The likely effect of the proposed use on the surrounding land uses will be minimal as the site is currently operation as a Sevice Station /Conveinece Store and Motor repair workshop located on a Road Zone 1 (RDZ1). A service station in this location will continue to provide a service to the local community, serving the current and future business and residential communities. The design is of a contemporary built form that responds to the scale and form of existing and emerging development. A low rise single storey, built form that will not adversely impact the immediate area and surrounds improving the overall amenity and landscaping. Furthermore, the siting and design of the proposed development will not have any unreasonable shadowing to adjacent properties. The open forecourt of the development and the siting of the crossovers allow for clear view lines to be maintained along both roadways thereby maintaining acceptable safety standards for vehicles and pedestrians. Advertising signs are consistent with typical service station signage advertising the nature of the use and the proposed products and services offered.


The accompanying drawings and reports show the swept path diagrams have been designed to facilitate the safe, efficient and functional movement of vehicles and maintain clear view lines for the safety of pedestrians. The provision for car parking spaces is appropriate in satisfying the demands of the proposed development taking into account the fact that the pump forecourt is also capable of accommodating the parking of stationary vehicles whilst being refuelled. In conclusion, it is evident that the built form and use responds to the intent of the Industrial 3 Zone and Commercial Zone to achieve a good balance. For these reasons and the views expressed in the supporting documentation the proposal represents an appropriate and desirable planning outcome that should be supported.

The subject site is located in Portland, on the west side of Percy Street, north of the juncture of Percy

Street and Otway St, as shown in Figure 1.

Figure 1 Site Location

Copyright Melway Publishing

The site is currently occupied by a BP service station, with access to the site provided from separate

crossovers located at the southern and northern ends of the site frontage to Percy Street. The

service station provides four double-sided bowsers, with an associated convenience shop at the

southern end of the site.

The site has a frontage of approximately 62 metres to Percy Street and a total site area of

approximately 2,750m2.

Land use in the immediate vicinity of the site is varied, with largely residential uses to the west and a

mix of commercial uses to the north and south along Percy Street.

The site is located within an Industrial 3 Zone (IN3Z).

Subject Site

2.2 Road Network

2.2.1 Percy Street

Percy Street is an urban collector road generally aligned north-south, intersecting with Glenelg

Street in the south, and connecting through to New Street in the north.

Percy Street provides a single traffic lane and on-road bike lane in each direction, with a painted

median accommodating a right-turn lane into the site. A combination of parallel and angle

kerbside parking are provided on both sides.

A 60km/h speed limit applies to Percy Street in the vicinity of the site.

2.3 Sustainable Transport

There are two public bus services that operate in Portland, comprising the Portland North (Route 1)

and Portland South (Route 2) bus services.

The Portland North (Route 1) service provides good public transport access to the site, with the

service looping around North Portland and allowing passengers to alight within 300 metres walking

distance of the site.

The public transport network map is provided in Figure 2

Satisfied


Page 9

4.2.2 Design Standard 2 – Car Parking Spaces

All car spaces on-site are proposed with a minimum width of 2.6 metres, length of 5.5 metres and

are accessed from aisles of no less than 6.4 metres in excess of the Planning Scheme requirements.

The accessible parking space and shared space are dimensioned in excess of the requirements of

the Australian Standard for Off-Street Parking for People with Disabilities AS2890.6 and are

considered appropriate.

4.3 Clause 52.12 – Service Station

Clause 52.12 of the Planning Scheme provides specific requirements with regards to the use of a

service station to ensure that the use of the land for a service station does not impair traffic flow or

road safety.

The relevant items with regard to car parking and traffic are discussed in Table 2 below.

Table 2 Service Station Design Requirements

Category Requirement Comment

Site Area

and

Dimensions

➢ The site must be at least 1,080 square metres.

➢ The frontage must be at least 36 metres (30

metres if the site is on a corner) and the depth at

least 30 metres.

The subject site exceeds

these minimum

dimensions.

Crossovers

No more than 2 vehicle crossovers may service the

site from a road and at the road alignment a

crossover must be:

➢ No wider than 7.7 metres.

➢ At least 4.5 metres from another crossover on the

site.

➢ At least 4.5 metres from another road or if a

splayed corner, at least 7.7 metres from the splay.

➢ At least 1.8 metres from a crossover on another

property.

All of these criteria are

satisfied with the

exception of the crossover

width. Wider crossovers

are required to

accommodate larger

vehicles. Refer to

discussion below.

Kerb or

Barrier

➢ Except at crossovers, a kerb or barrier must be

built along the road alignment to prevent the

passage of vehicles.

Kerbing is provided along

the frontage of the site.

Road

Setbacks

➢ A wall of a building must be at least 9 metres

from a road.

➢ A canopy must be at least 2.5 metres from a

road.

➢ Petrol pumps, pump islands, water and air supply

points and storage tank filling points must be at

least 3.6 metres from a road.

➢ Petrol tankers must be wholly on the site when

storage tanks are being filled.

➢ Driveway space must be sufficient to enable a

vehicle 13.8 metres by 2.5 metres to enter and

leave the site without reversing

➢ No vehicle may be serviced unless it is wholly on

the site.

The above elements have

been achieved in the

design. Swept path

diagrams are provided in

Appendix A

demonstrating petrol

tanker access.


Page 10

Trailers for

Hire

If trailers are for hire on the site:

➢ The site must be at least 1,080 square metres.

➢ All trailers must be wholly on the site and must not

encroach on landscaping or car parking areas or

accessways.

➢ On a corner site, a trailer higher than 1 metre

must be parked at least 9 metres from the corner.

No trailer hire facilities are

proposed on the site.

It is acknowledged that the crossover widths are in excess of 7.7 metres specified above, however

these crossovers have been designed specifically to accommodate the swept paths of a 19 metre

semi-trailer associated with the existing service station use. No alterations to the existing crossovers

are proposed.

4.4 Clause 52.13 – Car Wash

Clause 52.13 of the Planning Scheme provides specific requirements with regards to the use of a

car wash to ensure that the use of the land for a service station does not impair traffic flow or road

safety.

Relevant traffic engineering requirements are discussed in Table 3.

Table 3 Clause 52.13 Requirements

Category Requirement Comment

Crossovers

No more than 2 vehicle crossovers may service the

site from a road and at the road alignment a

crossover must be:

➢ No wider than 7.7 metres.

➢ At least 4.5 metres from another crossover on the

site.

➢ At least 4.5 metres from another road or if a

splayed corner, at least 7.7 metres from the splay.

➢ At least 1.8 metres from a crossover on another

property.

As above, all of these

criteria are satisfied with

the exception of the

crossover width. Wider

crossovers are required

to accommodate larger

vehicles. Refer to

discussion above.

Kerb or

Barrier

➢ Except at crossovers, a kerb or barrier must be

built along the road alignment to prevent the

passage of vehicles.

As above, kerbing is

provided along the

frontage of the site.

Queuing

Lane

➢ A queuing lane on the site must be able to

accommodate at least 10 vehicles before entry

to the car wash.

➢ If petrol is available for sale to vehicles queuing to

be washed, the lane must be able to

accommodate at least 10 vehicles before the

petrol selling point.

➢ The lane must be clearly shown on the ground

and marked for use only by vehicles queuing to

be washed.

➢ The area between the exit from a car wash and

the nearest crossover must be able to

accommodate at least 2 vehicles in single file.

Refer discussion below

The queuing area on approach to the car wash may accommodate approximately eight vehicles

before circulation to other parts of the site is impacted.


Page 11

Given the nature of a manual car wash bay, being utilised in largely an opportunistic manner, it is

considered very unlikely that patrons will opt to wait should there be considerable queues. As such,

it is considered that queueing area for eight vehicles is sufficient.

Whilst line marking for designated queueing lanes is currently not proposed, it may be introduced

as required by Council.

4.5 Fuel Tanker Access

The fuel fill point is to be located to the immediate north of the easternmost fuel bowser.

Tankers will enter the site from the southernmost Percy Street access and prop at the fill point,

allowing vehicles to safely and conveniently pass a stationary fuel tanker. Swept paths are

provided in Appendix A illustrating the swept path of a petrol tanker (26m B-Double).

4.6 Loading and Waste Collection

The loading bay has been designed to accommodate trucks 8.8m length (medium rigid truck).

Swept paths are also provided in Appendix A demonstrating access to the loading bay.

5 BICYCLE PARKING CONSIDERATIONS

The bicycle parking requirements for the subject site are identified in Clause 52.34 of the Glenelg

Planning Scheme.

No rate is listed within the scheme for petrol station use, and whilst the convenience shop falls

under the banner of the ‘shop’ land-use classification, there is no trigger for shop uses less than

1,000m2 floor area.

Similarly, no rate is listed within the Planning Scheme for car wash use and as the car wash

component only attracts car drivers, it clearly doesn’t generate a requirement for bike parking.

As such, the development does not trigger any requirements for bicycle parking.


Page 12

6 CAR PARKING CONSIDERATIONS

6.1 Statutory Car Parking Requirements

6.1.1 Car Parking Requirements – Clause 52.06

The car parking requirements for the subject site are identified in Clause 52.06 of the Glenelg

Planning Scheme, which specifies the following requirement for the convenience store component

of the proposed development.

Table 4 Clause 52.06 – Car Parking Requirements

Use Area Rate Car Parking Measure Total

Convenience shop 120 m2 10 To each premises 10

It is noted that no rate is listed within the clause for the petrol station or the car wash use on-site. In

this regard, Clause 52.06 states:

“Where a use is not specified in Table 1 or where a car parking requirement is not specified

for the use in another provision of the planning scheme or in a schedule to the Parking

Overlay, before a new use commences or the floor area or site area of an existing use is

increased, car parking spaces must be provided to the satisfaction of the responsible

authority.”

As such, the development requires 10 car spaces to be provided on-site, plus any additional

parking required by Council for the service station and the car wash uses.

It is proposed to provide a total of twelve car spaces to service the proposed development.

To confirm the appropriateness of the proposed supply, a review has been undertaken below to

confirm that sufficient parking is provided on-site.

6.2 Review of Car Parking Provision

The proposed convenience shop/service station functions primarily as a petrol outlet rather than a

shop and is unlikely to attract a significant number of shoppers beyond those already purchasing

fuel. Notably, the use comprises only 120m2 floor area and will provide a limited range of

convenience goods for sale.

Based on the above, the vast majority of the service station patronage will be that of motorists

purchasing fuel. These patrons typically proceed to the kiosk to pay for the fuel without moving

their vehicles from the position occupied during refuelling and therefore do not require a separate

parking space. In effect, eight parking spaces are provided at the fuel bowsers for this type of

parking demand.

On occasion, the use may generate some additional parking demand for customers purchasing

convenience goods. It is not anticipated that demands will exceed four parking spaces.

In addition to customer parking demands, the use will also attract regular demands associated with

an employee who operates the kiosk, and the parking of perhaps an additional employee during

the changeover of shifts.

The car wash functions as a hand car wash, whereby drivers enter the car wash bay and use the

car wash facilities to clean their own car. As such, when the car wash is being used it generates no

demand for parking outside of the two dedicated wash bays provided on-site.

A queueing area is provided to the rear of the car wash bays, capable of accommodating up to

eight queued vehicles. Given the provision of this queueing area, it is not anticipated that any

additional parking demands will be generated across the site.


Page 13

In addition, as the car wash is a self-service car wash, there are no employee demands associated

with the use, as it is assumed that service station staff will maintain the facilities required for

customer operation of the car wash.

In total, the service station and convenience shop uses are expected to generate demand for up

to six parking spaces, and the car wash is not anticipated to generate any parking demands at all.

With 11 customer parking spaces (excluding the air and water space) to be provided on-site, the

provision of parking will far exceed the development-generated demands.


Page 14

7 TRAFFIC CONSIDERATIONS

7.1 Traffic Generation

7.1.1 Service Station

The volume of traffic generated by a service station depends on the location of the site, time of

day, surrounding traffic volumes, and whether a convenience store or other uses are included in

the development.

As noted above, the subject site has previously operated as a BP (British Petroleum) service station

with associated convenience store. Comparable in size, the previous service station contained

eight fuel pumps and an associated convenience shop with a floor area of approximately 120m2,

which is the number of pumps and the approximate floor area of the convenience shop proposed

for this development.

Noting that the BP service station was operating at the time of writing, it is anticipated that the

traffic generation associated with the proposed service station and convenience store component

of the development will be equivalent to that of the traffic generated by the current service

station/convenience store development. In view of this it anticipated there will be no additional

traffic generated for the service station/convenience store component.

7.1.2 Car Wash

The proposed car wash will contain two manual car wash bays. Case study data collected for

both automatic and manual car wash bays indicates that they typically generate in the order of 4-

6 vehicle movements per bay during the AM and PM commuter peak hours.

Based on the above rates, it is anticipated the car wash will generate a total of 10 vehicle

movements in the AM peak and a total of 10 vehicle movements in the PM peak period.

It is important to note that a large majority of vehicles utilising the car wash facility comprise of

passing trade, i.e. vehicles that are already on the adjacent road network which are merely

diverted to the site from a broader trip purpose. As such, these trips do not represent additional

vehicle movements on the road network.

Furthermore, it is acknowledged that a considerable number of the vehicle trips to the car wash

facility will be directly associated with petrol station trips.

7.2 Traffic Impact

Reviewing the volumes above, it is projected that the proposed redevelopment will generate up to

10 additional vehicle movements during the peak hours from the existing conditions.

This is equivalent to one additional movement (in or out) every six minutes to Percy Street and as

such is not expected to have any considerable impact on the operation of the surrounding road

network.

8 CONCLUSIONS

It is proposed to develop the subject site for the purposes of a service station, with 4 double-sided

bowsers, and an associated convenience shop and car wash.

Considering the analysis presented above, it is concluded that:

➢ The proposed car parking and access design is considered appropriate;

➢ The use does not generate any requirement for bicycle parking;

➢ The car parking layouts and accesses have been designed generally in accordance with the

requirements of the Planning Scheme and are considered appropriate;

➢ The proposed provision of parking is considered sufficient to meet anticipated demands;

➢ The anticipated traffic volumes generated by the development are not expected to have an

impact on the operation of Percy Street or the surrounding road network and;

➢ There are no traffic engineering reasons which should preclude a permit from being issued for

this proposal.

22nd February 2018 Report Ref. 18012 Title: Determination of Noise Limit as per SEPP N-1 regarding proposed

manual car wash and vacuum facility at 145a Percy Street, Portland, Victoria and assessment of likely compliance.

Brief: Determine Effective Noise Levels and Noise Limits as per State

Environment Protection Policy N-1 (Control of Noise from Industry, Commerce and Trade) at nearest residences re proposed manual car wash and vacuum facility at 145a Percy Street, Portland, Victoria.

1.0 Introduction Audiometric & Acoustic Services has been appointed as part of a Planning Permit Application No. 17111 in relation to the proposed carwash facility at 145a Percy Street, Portland, Victoria. The Glenelg Shire has requested that the Client submit an “acoustic report and proposed noise attenuation methods.” The aim of this assessment is to determine the Noise Limits when any relevant EPA Policy is applied. In this case the EPA’s Policy Noise from Industry in Regional Victoria (NIRV) is not applicable as the population is greater than 7000. Specifically, NIRV requires the Limits to be set according to the State Environment Protection Policy N-1 (Control of Noise from Industry, Commerce and Trade) No. N-1 or SEPP N-1. Accordingly, we will use data from previous reports undertaken by this firm for car wash use to calculate proposed noise levels. 2.0 Description of Facility The car wash will be manual in operation with two vacuum units and two wash bays. Entry and exit to the site will be from Percy Street. We are anticipating a combined 5 cars per half hour as likely worst case scenario. SEPP N-1 requires the proposed measurement period to be of 30mins. No noise attenuating doors are proposed in the design of wash bays. It is our understanding that the facility is to be fitted with a central vacuum system which places the drive motor and vacuum pump within the plant room. This is a sensible and practical method of noise control from vacuums. However, it should be noted that some vacuum units are noisier than others, despite the centralizing of the equipment. We recommend that that vacuum units be specified for purchase as quiet operation units. The generating zone is specified on the drawings provided as Industrial (IN3Z) and the nearby residents are specified as Commercial Zone 2 (C2Z) and General Residential (GRZ1). Our area of concern is primarily for #4a, #5 and #6 Tanner Court and #16 Otway Street, Portland. Figure 1 Zoning areas adjacent to 145a Percy Street Portland

3.0 Operating Hours The Client has asked for 24hrs per day to be assessed and for the proposed hours to reflect any restrictions SEPP N-1 may allocate. 4.0 Applicable EPA Policy – SEPP N-1 4.1 Noise Limits - Times Noise limits are specified by the State Environmental Protection Policy (Control of Noise from Industry, Commerce and Trade) No. N-1 or SEPP N-1. This Policy prescribes noise limits for commercial, industrial or trade premises. The goal of the Policy is to protect residential areas from commercial, industrial or trade noise that may affect the general use of a noise sensitive area. SEPP N-1 guidelines prescribe different levels for different times of the business day and can be defined as follows: Day 0700—1800 Monday—Friday 0700—1300 Saturdays Evening 1800—2200 All Days 1300—1800 Saturdays 0700—1800 Sundays and Public Holidays Night 2200—0700

The Policy prescribes what is known as the Effective Nose Level from the commercial or trade site, meaning the level of noise emitted from the source that is received after adjustments at the nearest noise sensitive receiver (in this case a residential property). Additionally, it identifies the noise limit at the nearest residence which is calculated taking into account the measured background noise level at the subject premises and the zoning levels. This Policy is specified in this report for the purpose of determining whether the commercial premises will likely comply with the EPA’s SEPP N-1 Noise Limits in assessing its potential impact on the defined residential premises of #4a, #5 and #6 Tanner Court and #16 Otway Street, Portland. 4.2 SEPP N-1 Noise Limit Criteria and Measurements 4.2.1 Background Noise Measurements re #5 Tanner Court, Portland. A noise logger was set up on the fence line of #5 Tanner Court and 145a Percy Street from approximately 1530hrs on Friday 26th January until 1100hrs on Friday 2nd February 2018. The weather was fine though at times the wind was moderately elevated. The logger is not believed to be affected by wind. We see no significant difference in the prevailing background noise across the measurement period. Background Noise Measurement – Noise Logger Results The following L90 measurements have been averaged over the EPA time periods.

Table 1: SEPP N1 Background Level – 26/2/2018 – 2/2/2018 at 5 Tanner Court Average L90 dB(A) Average EPA Day Period 46 Average EPA Evening Period 43 Average EPA Night Period 36

A confirmation spot measurement was taken on Monday 29/2/18 at street front of #6 Tanner Street, Portland by sound level meter. The result as are as per Table 2. This corresponds well with the data collected by the logger for the average Day Period. Table 2: SEPP N1 Background Level on Monday 29/2/18 at street front of #6 Tanner Street, Portland L90 dB(A) Day Period 44

The measurements of the prevailing background noise for Tanner Street residents above are believed to be neutral and representative of the area. 4.3 Noise Limits applicable at Residences Table 3 details the Noise Limits for the EPA time periods. The Limit for any SEPP N-1 related items have been set by applying the Zoning Levels via the Influencing Factor of 0.44 as extrapolated from the SEPP N-1. The Noise Limits for the Night Period are based on Low Background Levels whereas the Zoning Limits apply to the Evening and Day Periods. Table 3: SEPP N-1 Limits

5.3 Calculations of Noise Levels at Nearest Residences The following are our calculations for the possible noise levels of the measured LAeq for a continuous 30 minutes period without any form of acoustic barrier. We believe this scenario to be possible should 2 or 3 cars be alternating between wash cycles and vacuum cycles as both activities typically take 15mins.

*All units in the table above are in dB(A) Table 3 above shows exceedances for both the vacuum units and the manual wash bays. We believe a suitable barrier needs to be designed to sufficiently attenuate noise emanating from the site as per Section 6. 6.0 Acoustic Barrier Design Due to the close proximity of the nearest residence and the projected exceedances, it is necessary to create a suitable barrier to reflect/attenuate the emitted noise. The acoustic barrier is proposed to extend the full length of the south and west property lines as per Figure 2, at a minimum height of 2.7m. We have performed calculations for the effective noise level with the proposed barrier at a height of 2.7m. The results are as per Table 4.

*All units in the table above are in dB(A) We recommend the following construction for the acoustic barrier:

• Minimum 90mm timber stub frame with 7.5mm Blueboard or equivalent cement sheeting fixed to both sides.

A neat fit is required with no gaps. The cement sheet should be dug minimum 50mm into the ground to ensure no breakout of noise under the fence. Figure 2

Page 9 of 12

7.0 Plant Room. The plant room is in an acoustically appropriate location, however it will need to be constructed of a suitable material. We recommend the following construction:

• Walls: Double brick construction with min 20mm cavity or min 140mm core filled Besser block construction.

• Access door: Must achieve a minimum Rw 35 and face Percy Street. A neat fit is required.

• Ceiling/Roof: Colorbond metal deck or Concrete tile with R3.5 fibrous batts and min 6mm cement sheet lining.

Please advise if any ventilation is needed for plant room as this will cause breakout of noise from the structure. 8.0 Recommended Operating Periods The proposed effective noise levels from the wash bays and vacuum systems are considered to be compliant with SEPP N-1 for the Day and Evening Periods however the results are marginal for the Night Period. SEPP N-1 requires a 30min effective LAeq to be used in calculations. In laymen’s terms the LAeq is the average noise level. This does not take into consideration the intermittent spikes in level (LMax) or any criterion for sleep disturbance. As the distance from the source to the nearby residents is moderate, and the reflective nature of the wash bay, we don’t believe that an increase in height of the noise barrier would be effective. We recommend that the wash bay and vacuums operate during the EPA Day and Evening Period, and that analysis of Night Period operations is undertaken once the car wash is up and running. Confirmation of Night Period compliance would involve a simulated test similar to Section 5.2 of this report to be undertaken at a time and day when the ambient background level is low. For example, a Sunday night after 10pm or before 7am. 9.0 Summary The proposed effective noise levels from the wash bays and vacuum systems are considered to be compliant with SEPP N-1 for the Day and Evening Periods with the proposed 2.7m barrier, however the results are marginal for the Night Period. We believe the situation to be low risk of annoyance to nearby noise sensitive receivers if recommendations as per Section 7 and 8 of this report are implemented. Confirmation of Night Period compliance will need to be undertaken insitu at a later date. Please feel free to contact us should any additional detail be required. This applies to any other parties that have legitimate access to this report.
