1.6 CONSENT

Approval for Hospital {Alterations and Additions) was granted via DA 372/2018(1) on 16 April 2019. The key elements of the original consent are

summarised as follows:


Application to Modify Consent - DA 372/2018(1} Page 3

• The construction of a building extension along the Wolsley Street frontage

of the hospital to provide 30 new single-bed rooms and support areas including administration, consult rooms, group room, lounge/patient

dining room, and courtyard.

• Minor internal alterations to the existing building to convert shared rooms to single bed rooms.

• Minor extension at the southern end of the existing building to slightly

enlarge an existing dining area.

• Relocation of the existing oxygen vessel compound.

• Construction of new vehicle areas including a new access onto Wolsley Street; internal driveway; drop-off zone; loading zone; and parking spaces.

• The proposed alterations and additions have been designed to remain largely consistent with the architecture and finishes of the existing building.

• Overall, the development, which also involves the conversion of existing shared rooms to single-bed rooms, will result in a net increase of 18 beds

to bring the total for the entire hospital to 79 beds.

1.7 PROPOSED MODIFICATION

1.7.1 Amendments to Floor Plan

With reference to the attached plans, it is proposed to modify the floor plan as

follows:

a) A revised layout is proposed for the non-ward areas, generally in the north

western section of the proposed extension. This generally involves reconfiguration of the main entrance, reception area, administration areas,

consult rooms, group room, lounge/patient dining room (LNPT/DIN}, gym, and courtyard. The key changes are:

• The main entrance doors will be shifted slightly further to the west and the airlock will shift further north into the currently approved

undercover area at the main entrance.

• The reception counter will be positioned so as to provide direct line of

site to the main entrance doors.



• The WC will be located just inside the main entrance doors

• The office, consulting rooms and general support spaces will be generally rearranged.

• The gym will be relocated to the western side of the addition to take the place of a single bed room; and a new single bed room will be created generally in the space of the currently approved gym.

• The courtyard will be modified in shape and the timber deck will be made smaller and a larger area of landscaping will be provided.

• The day group room will be provided with openings onto the fenced outdoor area.

b) Instead of constructing a minor extension at the southern end of the existing building to slightly enlarge the existing dining area; it is now

proposed to expand the existing dining area into adjacent space within the

existing building. This will involve the consumption of a single bed room in that section of the building. There will now be no change to the external

appearance of the building in this location.

c) The conversion of shared rooms to single bed rooms will involve a minor

configuration to the approved layout to enable the creation of a new single

bed room to compensate for the room that will be lost as a result of the proposed expansion of the existing dining room (refer point (b) above).

Despite the floor plan changes, the number of beds will remain as approved. With reference to DUD1-P-G Issue 5, the total number of beds is 79 as follows:

Ward Beds

Mental Health 26

Surgical/Rehabilitation 4

Medical/Surgical 17

Rehabilitation 24

Paediatric 4

High Dependency 4

TOTAL 79



1.7.2 Amendments to External Appearance

The external appearance of the building will be altered mainly to reflect the proposed floor plan changes but also to address revised external site levels as

a result of more detailed engineering assessment. Otherwise, the building will

remain largely as approved in terms of roof profile, height and footprint.

With reference to the attached plans, it is proposed to modify the external

appearance as follows:

a} The canopy of the main entrance will be made smaller from east to west.

b} The courtyard fencing will be adjusted to follow the amended courtyard arrangement. Further, the fence materials will now comprise sections of

compressed fibrous cement (CFC} clad lightweight walls (instead of pre

cast concrete} with infill sections of Crimsafe screen mesh.

c} Due to site levels, a retaining wall below slab level will now form part of the

northern wall ofthe lounge/patient dining room and a suspended slab with a void below is proposed along the western side. This will give the building a taller appearance along the Wolsley Street elevation as greater wall

height will be exposed. However, comparison between the approved plans and the proposed modification will show that the top-of-roof or ridge heights of the building remain as approved. The taller wall height has been addressed by scaling down the facade by means of an aluminium batten

screen panel in a grey finish along the lower section of wall.

d} As a result of the proposed retaining wall and immediate ground levels, the approved aluminium slat fencing along the western (Wolsley Street}

elevation of the building; and the approved enclosure along the western side of the courtyard will now sit lower in relation to the building itself.

e} A full height mesh screen (Crimsafe or similar} will be provided in front of the full height glazed wall along the northern elevation of the lounge/patient dining room. The screen is intended to offer shading for the glazing and fall protection along the edge of the timber deck in the

courtyard.

f} The full height glazing on the northern and western elevations of the lounge/patient dining room will comprise sections of coloured back panel

to assist with energy efficiency.

g} The proposed fascia of the skill ion element will be made finer. Peter Basha

Planning & Development


d) As mentioned earlier, there will now be no change to the external

appearance of the existing building in relation to the proposed expansion of the existing dining area.

1.7.3 Amendments to Site Layout

The building footprint and siting remain essentially as approved. However

minor changes to the site layout are proposed as follows:

a) The proposed vehicle access point onto Wolsley Street will be shifted further north. The currently approved distance between the access point

and the northern boundary is approximately 10 metres. The proposed

modification will see this distance reduce to 3 metres.

b) The proposed courtyard shape will be reconfigured and will project slightly

further north. As currently approved, the courtyard is approximately 15.8 metres from the northern boundary. Under the proposed modification, the distance between the courtyard and northern boundary will range

between approximately 10 to 15.8 metres.

1. 7 .4 Proposed Staging

With reference to the plans, the development will proceed in 2 stages:

a) Stage 1 would involve:

• Expansion of the existing dining room.

• Conversion of shared rooms to single bed rooms.

• Construction of the new wing (running north south) that provides 15

mental health ward beds; 4 rehabilitation ward beds; lounge/patient dining room; day group room; consult rooms; gym; and the

reception/administration/support areas.

• Provision of the drop-off zone and a temporary accessible parking space near the main entrance to the extension. These areas will be sealed as required to accommodate vehicle manoeuvring and will be served by the existing driveway that extends from March Street along

the eastern and northern sides of the existing hospital building. The

temporary parking space will be removed for Stage 2.

• Construction of the courtyard.



• Fencing/screens and landscaping along the western side of the building.

• Provision of landscaping along the northern and western sides of the

courtyard.

• A temporary 1200mm chainwire fence (black coated or similar) that extends from the north western corner of the courtyard to the northern

boundary. This fence will prevent access to the site from Wolsley Street but will be removed for Stage 2.

b) Stage 2 would involve:

• Construction of the new wing (running east west) that provides the 11 mental health ward beds and office.

• Construction of the new access onto Wolsley Street.

• Provision of landscaping along the northern side of the new Wolsley

Street access and driveway.

• Construction of a 2100mm solid timber fence along part of the northern boundary as shown on the site plan to serve as an acoustic barrier

between the new access and the existing dwelling at 22 Wolsley Street.

• Construction of the new driveway and 10-bay car parking area.

• Relocation of the oxygen vessel compound.

Condition 22


Landscaping shall be installed in accordance with the approved plans prior to the issuing of an Occupation Certificate, and shall be permanently maintained to the satisfaction of Council's Manager Development Assessments.



Application to Modify Consent - DA 372/2018{1) Page 11

Landscaping for each stage of the development shall be installed in accordance with the approved plans prior to the issuing of an Occupation Certificate for each stage of the development, and shall be permanently maintained to the satisfaction of Council's Manager Development Assessments.

Condition 23


A total of 85 off-street car parking spaces shall be provided upon the site in accordance with the approved plans, the provisions of Development Control Plan 2004, and be constructed in accordance with the requirements of Council's Development and Subdivision Code prior to the issue of an Occupation Certificate.


At the completion of Stage 2, a total of 85 off-street car parking spaces shall be provided upon the site in accordance with the approved plans, the provisions of Development Control Plan 2004, and be constructed in accordance with the requirements of Council's Development and Subdivision Code prior to the issue of an Occupation Certificate.

This aspect of the modification is justified on the basis that the existing parking resources within the site would already provide the required amount of

parking. This is demonstrated in the parking assessment provided in the original SoEE (and reproduced below for convenience}.

Orange DCP 2004 requires parking for hospitals to be provided at the following rate:

1 space for every 3 beds

+ 1 space for each resident doctor and

I I

I +_l_s-pa_c_e_f_o_r_e_v_e_ry_2_e_m_p_lo_v_e_e_s __,

1 space for every 2 visiting doctor



As a result of the proposed development/modification, the parking

requirement for the hospital is summarised in the table below.

Component Parking Rate Spaces

79 Beds 1 space per 3 beds 27

I Nil Resident Doctor 1 space per resident doctor 0 I

10 Visiting Doctors (any one time) 1 space per 2 doctors 5

70 Staff (any one time) 1 space per 2 employees 35

TOTAL 67

As indicated in the submitted site plan, the existing hospital car park provides a total of 75 spaces, which already satisfies the parking requirements under DCP 2004 - 15 for the entire development. Notwithstanding, the existing

parking resources will be supplemented by the addition of another 10 parking

spaces at the completion of Stage 2, to take the total to 85 spaces.


Section2.0

TOWN PLANNING CONSIDERATIONS

In determining the application, Council must take into consideration the relevant matters under section 4.15 of the Environmental Planning and Assessment Act, 1979. These are assessed below.

2.1 PROVISIONS OF ENVIRONMENTAL PLANNING INSTRUMENTS

2.1.1 Orange Local Environmental Plan 2011

The modification is subject to Orange Local Environmental Plan 2011 (the LEP). A consideration of the relevant matters is provided below.

Zone Objectives

The land is zoned R2 Low Density Residential. The objectives of the zone are:

• To provide for the housing needs of the community within a low density residential environment.

• To enable other land uses that provide facilities or services to meet the day to day needs of residents.

• To ensure development is ordered in such a way as to maximise public

transport patronage and encourage walking and cycling in close proximity to settlement.

• To ensure that development along the Southern Link Road has an alternative access.

The proposed modification is not adverse to the zone objectives, as it does not involve a significant change to the nature, scale or general arrangement of the approved development.

Permissibility

DA 372/2018(1) was approved as a permissible use with recourse to with recourse to State Environmental Planning Policy {Infrastructure) 2007 and

remains as such. Peter Basha


Application to Modify Consent_:-_D_A_37_2~/2_0_1_8(~1~} _ Page 14

Pursuant to Section 4.55 of the Environmental Planning & Assessment Act,

1979 it is proposed to modify the consent in the manner described in this application. In order for Section 4.55 to apply, it must be determined whether

or not the proposed development is substantially the same as the development outlined in the consent.

In other modification applications, Council has referred to Tipalea Watson Pty Ltd v Kuringai Council 2003 and the matters that ought to be considered when determining whether or not the proposed modified development is

substantially the same as the development outlined in the consent. These matters are considered below.

Significant change to the nature or intensity of the use

The proposed modification does not change the nature or intensity of the use.

In this regard:

• It retains the basic or inherent features, character, and qualities of the approved alterations and additions to the hospital, with relatively minor changes to the floor plan, external appearance and site arrangement.

• The proposed modification does not change the number hospital beds or radically alter overall floor area.

The use, key activities and operation will remain largely as approved and would

not radically transform the development to the extent that it would fail the "test".

Significant change to the relationship with adjoining properties

The proposed modification will not significantly change the relationship to adjoining properties. In this regard:

• The siting and footprint of the approved building remains essentially as approved.

• The proposed change in site levels around the courtyard and lounge/patient dining room will expose more of the building to residents

in Wolsley Street but the visual impacts of such are considered acceptable. Peter Basha



• As a result of the proposed change in site levels, the approved aluminium

slat fencing along the western (Wolsley Street) elevation of the building; and the approved enclosure along the western side of the courtyard will now sit lower in relation to the building itself. The visual impacts of such are considered acceptable (refer Section 2.5.2 of this report).

• The proposed modification will result in the new access and its driveway moving slightly closer to the existing dwelling at 22 Wolsley Street. The

potential impacts in terms of noise and privacy can be addressed (refer Section 2.5.3 and Section 2.5.4 of this report).

• The proposed modification will result in the courtyard moving slightly closer to the existing dwelling at 22 Wolsley Street. The potential impacts

in terms of noise and privacy can be addressed (refer Section 2.5.3 and Section 2.5.4 of this report).

Adverse amenity impacts on neighbours from the changes

For the reasons provided in this report, the proposed modification would not

generate additional unacceptable impacts on neighbours in terms of land use conflict, privacy, visual impact, overshadowing, noise or residential amenity.

Significant change to the streetscape

The proposed modification will alter how the currently approved building will

appear in the Wolsley Street streetscape. However, the proposed external changes as described earlier in this report would not radically transform the

development to the extent that it would fail the "test".

The visual impacts of the proposed external changes are considered later in this report at Section 2.5.2 and are found to be satisfactory.

Change to the scale or character of the development, or the character of the locality

The proposed modification does change the scale or character of the development; or the character of the locality, and certainly not to an extent

that it would fail the "test". Peter Basha


Application to Modify Consent - DA 37~2/_2_01_8~(1~) P~ag~e_1_6_

In quantitative terms:

• The footprint, siting and arrangement of the development remain

essentially as approved.

• There is no increase in floor area.

• There is no increase in the number of hospital rooms/beds.

• Building height (RL) does not increase in terms of the top of roof and ridge

heights.

• The courtyard will project slightly further towards the north but this change will not transform the scale or character of the development or the

character of the locality .

• The new access onto Wolsley Street (and its driveway) will shift further north but this change will not transform the scale or character of the

development or the character of the locality.

• The proposed additional accessible parking space near the main entry to the extension will not transform the scale or character of the development

or the character of the locality.

The qualitative factors must also be considered. In this regard, there are no

aspects of the proposed modification that radically transform the character of

the development or the character of the neighbourhood. In particular:

• The approved use and its associated activities remain fundamentally the

same.

• The proposed modification retains the character and key attributes of the approved alterations and additions. There is nothing about the modification to suggest otherwise.

• The modification does not introduce any elements that would significantly change expectations about the approved development.

• For the reasons provided in this report, the proposed modification would not generate unacceptable impacts on neighbours in terms of land use

conflict, privacy, visual impact, overshadowing, noise or residential

amenity.


Application to Modify Consent - DA 372/2018{1) _____ Page 17

• The development as modified would remain consistent with the

development description provided on the Notice of Determination for DA

372/2018(1}.

On the basis of the above information, it is appropriate for the proposed modification to be dealt with pursuant to Section 4.55(2} of the Environmental

Planning and Assessment Act, 1979.

Clause 1.2 Aims of Plan

The aims of the LEP are as follows:

a} to encourage development that complements and enhances the unique

character of Orange as a major regional centre boasting a diverse economy

and offering an attractive regional lifestyle,

b} to provide for a range of development opportunities that contribute to the social, economic and environmental resources of Orange in a way that

allows the needs of present and future generations to be met by implementing the principles of ecologically sustainable development,

c} to conserve and enhance the water resources on which Orange depends,

particularly water supply catchments,

d} to manage rural land as an environmental resource that provides economic

and social benefits for Orange,

e) to provide a range of housing choices in planned urban and rural locations

to meet population growth,

f) to recognise and manage valued environmental heritage, landscape and

scenic features of Orange.

The proposed modification is not adverse to the aims of the LEP, as it does not involve a significant change to the nature, scale or general arrangement of the

approved development.

Clause 7.3 Storm water management

Clause 7.3 of the LEP applies. The objective of this clause is to minimise the impacts of urban stormwater on the land to which the development applies,

and on adjoining downstream properties, native bushland and receiving

waters.


Application to Modify Consent- DA 372/_20_1_8~(1~) Pa~g~e_1_8_

Generally, the proposed modification would not significantly alter the stormwater drainage arrangements that are planned to serve the approved development.

Clause 7.6 Groundwater vulnerability

The subject land is defined on the Orange Local Environmental Plan 2011 - Water Map as having groundwater vulnerability. Clause 7.6 of the LEP applies.

The objectives of this clause are to maintain the hydrological functions of key groundwater systems and to protect vulnerable groundwater resources from depletion and contamination as a result of inappropriate development.

There are no aspects of the proposed modification that would cause adverse or additional impacts on groundwater resources.

Clause 7.11 Essential services

Clause 7.11 states that development consent must not be granted to development unless the consent authority is satisfied that any of the following

services that are essential for the proposed development are available or that adequate arrangements have been made to make them available when required:

a) the supply of water,

b) the supply of electricity,

c) the disposal and management of sewage,

d) storm water drainage or on-site conservation,

e) suitable road access.

The proposed modification does not adversely affect the servicing or access arrangements that are planned to serve the approved development.

2.1.2 State Environmental Planning Policy 55 - Remediation of Land

Clause 7(1) of SEPP 55 Remediation of Land provides that a consent authority must not consent to the carrying out of any development on land unless:

a) It has considered whether the land is contaminated, and



b) If the land is contaminated, it is satisfied that the land is suitable in its

contaminated state (or will be suitable, after remediation) for the purpose for which the development is proposed to be carried out, and

c) If the land requires remediation to be made suitable for the purpose for

which the development is proposed to be carried out, it is satisfied that the land will be remediated before the land is used for that purpose.

The requirements of SEPP 55 were addressed as part of the original DA

determination. The proposed modification does not generate the need for

further consideration.

2.2 PROVISIONS OF DRAFT ENVIRONMENTAL PLANNING INSTRUMENTS

There are no known draft regional or state planning instruments that apply to

the subject land or proposed modification.

2.3 PROVISIONS OF DEVELOPMENT CONTROL PLANS

2.3.1 Orange Development Control Plan 2004 - 7 Development in Residential Areas

Planning Outcome 0.2-1 Interim Planning Outcomes - Conversion of Zones

Orange Development Control Plan 2004 - 7 Development in Residential Areas

applies to the subject land. However, the DCP only sets Planning Outcomes that are relevant to:

• Urban residential subdivision (typically in an estate situation).

• Residential development (dwellings, dual occupancies, multi-dwelling).

• Health consulting rooms (i.e. the re-use of a former dwelling).

• Shops and businesses.

• Exhibition homes.

• Home businesses.

• Bed and breakfast development.



• Development in the villages of Spring Hill and Lucknow.

• Development in the vicinity of Charles Sturt University.

The approved development does not fit within any of the above categories.

There are no Planning Outcomes in the DCP that are of particular relevance to this proposed modification.

2.3.2 Orange Development Control Plan 2004 - 15 Car Parking

For the reasons provided in Section 1. 7.5 {Condition 23) of this report, the

proposed parking resources are considered suitable for the development as

modified.

2.4 MATTERS PRESCRIBED BY THE REGULATIONS

The Environmental Planning and Assessment Regulation 2000 prescribes

certain matters that must be considered by Council.

There are no relevant prescribed matters that apply to the proposed

modification.

2.5 THE LIKELY IMPACTS OF THE DEVELOPMENT

The potential impacts of the proposed modification are considered below.

2.5.1 Traffic

The traffic impacts of the development were assessed as part of the original DA

considerations.

The modification does not intensify the activity or increase the scale of the

approved development. As such, there are no aspects of the proposed modification that are likely to cause adverse traffic impacts.

Notwithstanding the relocated access point and the proposed staging of the development, the access and on-site vehicle manoeuvring arrangements

remain generally as approved.

The proposed parking provision has been assessed as satisfactory.



2.5.2 Visual Impact

The visual impacts of the development were assessed as part of the original DA considerations and were found to be satisfactory.

The proposed modification will alter the external appearance of the approved

building particularly in relation to the Wolsley Street streetscape. The visual impacts are considered below.

The proposed alteration in site levels will cause the western wall of the lounge/patient dining room to look taller. However, the visual impact is

considered satisfactory due to the following:

• The overall building height does not increase. Building height (RL) remains as approved in terms of the top of roof and ridge heights.

• The expansive full height glazing along the western wall lends a lightweight and transparent quality to the building. The reduced fascia width also

assists in this regard.

• The continuation of the aluminium slat fencing along the subfloor section of the wall in conjunction with proposed additional landscaping will add visual interest and assist to disguise the wall height.

The addition of the screen mesh in front of the full height glazing in the northern elevation is satisfactory in terms of visual impact due to the following:

• It is a dark material and will be therefore be visually recessive.

• It does not present directly to the streetscape.

• It integrates reasonably with the architecture of the building.

The privacy screen/wall around the courtyard is an approved element in the current DA. The overall height of this structure has been reduced and will sit lower in relation to the building due to the revised site levels. The appearance

will be similar with reduced visual impact, except that CFC clad lightweight walls will be used instead of pre-cast concrete.

The 1800mm high fencing along the western side of the building is an approved element in the current DA. The height of this structure does not change but it

will sit lower in relation to the building due to the revised site levels. The

approved materials will be retained as part of the modification.


Application to Modify Consent_-_D_A_3_72~/_2_0_1_8~(1~) Pa--"'g,__e_22_

The building will appear more exposed as a result of the lower level of the fencing and courtyard screen/wall. However, this does not generate adverse

visual impacts because the building will contribute positively to the streetscape due to its well-articulated facade: appropriate architectural detailing; and the

complementary mix of external finishes.

2.5.3 Noise

The shifting of the proposed Wolsley Street entrance and the courtyard further

north has the potential to increase noise impacts upon the nearest neighbour to the north (at 22 Wolsley Street).

To address the potential noise impacts, the acoustic engineer for the project recommends that a solid fence be established along part of the northern boundary as follows:

• Fence height to be minimum of 2100mm high.

• Fence material to be solid surface (i.e. no openings) such as lapped and capped timber or colorbond panel.

• Fence to extend from the eastern edge of the dwelling towards Wolsley Street as far as practicable (having regard to site conditions and driver sightlines).

2.5.4 Privacy

The shifting of the proposed Wolsley Street entrance and courtyard further north has the potential to increase privacy impacts upon the nearest neighbour

to the north (at 22 Wolsley Street). The potential impacts can be addressed as follows:

• The recommended fencing along the northern boundary (to address potential noise impacts) would also address potential privacy impacts upon that neighbour.

• The common boundary with 22 Wolsley Street comprises a well established hedge and fencing which may filter views between that property and the hospital. However, it is proposed to establish additional landscaping in the area between the proposed new driveway and the common boundary to enhance this situation in terms of privacy.



The lowering of the fencing along the western side of the extension may perhaps reduce privacy between the proposed hospital extension and the existing dwellings opposite in Wolsley Street. However, the privacy impacts are

considered acceptable due to the following:

• The western edge of the hospital will remain relatively inactive given that there are no building entrances, parking areas and the like that face west.

• In terms of the existing context, it is reasonable to suggest that the privacy level would not change significantly, given that the windows of the existing

hospital are well elevated and have overlooked Wolsley Street (and vice versa) for many years.

• The existing and proposed landscaping along this side of the hospital will assist to filter views between the hospital and the opposite dwellings. In this regard, additional landscaping is proposed along the western edge of

the new building to address potential privacy impacts.

2.5.5 Water Quality

There are no aspects of the proposed modification that would cause adverse

or additional impacts on water quality.

2.5.6 Air Quality


or additional impacts on air quality.

2.5. 7 Lighting


or additional impacts in terms of lighting.

2.5.8 Overshadowing

There are no aspects of the proposed modification that would cause adverse or additional impacts in terms of overshadowing. It should be noted that building height (RL) remains unchanged.

2.5.9 Crime Prevention

The proposed modification does not diminish the potential for the

development to meet CPTED principles. Peter Basha



2.5.10 Social and Economic Impacts

Notwithstanding the benefits that improved health facilities bring, the proposed modification is considered neutral in terms of social and economic

effects.

2.6 THE SUITABILITY OF THE SITE FOR THE DEVELOPMENT

The proposed modification is not constrained by any factors relating to the suitability of the site or premises.

2.7 ANY SUBMISSIONS MADE IN ACCORDANCE WITH THIS ACT OR THE REGULATIONS

According to Orange Development Control Plan 2004 - 05 General Consideration for Zones and Development Council is not required to formally

advertise the modification application.

However, it is understood that Council will advertise the application given that

the original DA was advertised and the proposed modification has been made pursuant to Section 4.55(2) of the EPA Act, 1979.

2.8 THE PUBLIC INTEREST

The proposed modification is considered to be of only minor interest to the

wider public due to the relatively localised nature of potential impacts.


Section;.o

CONCLUSION

It is requested that the proposed modification as submitted be approved on the following grounds:

• Based on the information provided in this report and the attached plans, it is demonstrated that the development as modified is substantially the same

development for which the consent was originally granted.

• Following consideration of Section 4.15 of the Environmental Planning and Assessment Act, 1979, the potential impacts of the proposed modification are considered to be minimal.

• Accordingly, the proposed modification may be considered pursuant to Section 4.55(2) of the Environmental Planning and Assessment Act, 1979.

We trust that this application will be given favourable consideration by Council. Any further enquiries may be directed to our office on 6361 2955.

APPENDIX A - Noise Measurement Results


GLOSSARY OF ACOUSTIC TERMS

Most environments are affected by environmental noise which continuously varies, largely as a result of road traffic. To describe the overall noise environment, a number of noise descriptors have been developed and these involve statistical and other analysis of the varying noise over sampling periods, typically taken as 15 minutes. These descriptors, which are demonstrated in the graph below, are here defined.

Maximum Noise Level (LAmax) - The maximum noise level over a sample period is the maximum level, measured on fast response, during the sample period.

LA1 - The l..41 level is the noise level which is exceeded for 1 % of the sample period. During the sample period, the noise level is below the LA1 level for 99% of the time.

LA10 -The LA10 level is the noise level which is exceeded for 10% of the sample period. During the sample period, the noise level is below the LA10 level for 90% of the time. The LA10 is a common noise descriptor for environmental noise and road traffic noise.

LA9o - The LA9o level is the noise level which is exceeded for 90% of the sample period. During the sample period, the noise level is below the LA90 level for 10% of the time. This measure is commonly referred to as the background noise level.

LAeq - The equivalent continuous sound level (LAeq) is the energy average of the varying noise over the sample period and is equivalent to the level of a constant noise which contains the same energy as the varying noise environment. This measure is also a common measure of environmental noise and road traffic noise.

ABL- The Assessment Background Level is the single figure background level representing each assessment period (daytime, evening and night time) for each day. It is determined by calculating the 10th percentile (lowest 10th percent) background level (LA9o) for each period.

RBL - The Rating Background Level for each period is the median value of the ABL values for the period over all of the days measured. There is therefore an RBL value for each period - daytime, evening and night time.

2.3 The Proposal

Development consent is sought for alterations to the Dudley Private Hospital. The proposal involves:

• The construction of a building extension along the Wolsley Street frontage of the hospital to provide 23 new single bed rooms and support areas including administration, consult rooms, group room, patient dining/lounge/activity room, and courtyard;

• Minor internal alterations to the existing building to convert shared rooms to single bed rooms;

• Minor extension at the southern end of the existing building the slightly enlarge an existing dining area;

• Relocation of the existing oxygen vessel compound;

• Construction of new vehicle areas including a new access onto Wolsley Street, internal driveway, drop-off zone, loading zone, and parking spaces; and,

• Removal of some trees.

Overall, the development, which also involved the conversion of existing shared rooms into single bed rooms, will result in a net increase of 18 beds to bring the total for the entire hospital to 79 beds.

The proposed additions to the site are shown in Figure 2-3.

3 EXISTING NOISE ENVIRONMENT

To establish existing background noise levels at the most potentially affected residential receivers, unattended noise monitoring was conducted at 23 Lucas Street between 7 December and 18 December 2018. The noise monitoring location is shown in Figure 3-1.

Figure 3-1 Noise Monitoring Location

• Receivers e Logger

(9 50 100 m ,

WILKINSON t MURRAY

The noise monitoring equipment used for these measurements consisted of an environmental noise logger set to A-weighted, fast response. This equipment is capable of remotely monitoring and storing noise level descriptors for later detailed analysis. The equipment calibration was checked before and after the survey and no significant drift was noted.

From the background noise levels (LA9o) the Rating Background Levels (RBLs) were determined using the methodology recommended in the NSW Noise Policy for Industry(the NPfl). During the data analysis, it was discovered that the majority of data from the daytime and evening periods was affected by extraneous noise from insects and that the RBL could not be established in these periods. The night time data was not affected by extraneous noise.

The existing ambient noise levels are presented in Table 3-1. Daily plots of the noise logger data are presented in Appendix A.

4 OPERATIONAL NOISE ASSESSEMENT

4.1 Assessment Approach

The Dudley Private Hospital has been located at the March Street site since 1979 and is considered to be part of the existing noise environment. Accordingly, this assessment focuses on new and significantly modified noise sources and activities introduced by the Proposal. Specifically, the new sources and activities are:

• Vehicle movements associated with the additional car-parking spaces near the building extension, accessing the site via Wolsley Street;

• Additional mechanical plant associated with the building extension; and,

• Oxygen tanker truck accessing the new vessel location via the Wolsely Street entrance.

On the basis that intrusive noise levels from sources introduced by the Proposal comply with relevant noise trigger levels, it is considered unlikely that the overall operation of the hospital would affect the acoustic amenity of nearby receivers.

4.2 Operational Noise Trigger Levels

The Noise Policy for Industry (NPfI) (EPA, 2017) provides a framework for assessing environmental noise impacts from industrial premises and industrial development proposals in New South Wales.

The NPfI recommends the development of project noise trigger levels, which provide a benchmark for assessing a proposal or site. The project noise trigger levels should not be interpreted as mandatory noise criteria but, rather, as noise levels that, if exceeded, would indicate a potential noise impact on the community.

The project noise trigger level is the lower value of the project intrusiveness noise level and the project amenity noise level. The project intrusiveness noise level assesses the likelihood of noise being intrusive above the ambient noise level and is applied to residential receivers only. The project amenity noise level ensures the total industrial noise from all sources in the area does not rise above a maximum acceptable level.

4.2.1 Project Intrusiveness Noise Levels

The intrusiveness noise level is the noise level 5 dBA above the background noise level for each time period (daytime, evening or night time) of interest at a residential receiver. The background noise level is derived from the measured LA9o noise levels.

The NPfI stipulates that project intrusiveness noise levels should not be set below 40 dBA during the daytime and 35 dBA in the evening and night time. Additionally, the NPfI recommends that the project intrusiveness noise level for evening is set at no greater than that for the daytime, and that the project intrusiveness level for night time is set at no greater than that for the evening and daytime.

Since the daytime and evening noise monitoring data was affected by extraneous noise, the minimum project intrusiveness noise level of 40 dBA has been adopted for the daytime and both the evening and night time project intrusiveness noise levels have been set based upon the

.@



measured night time RBL. Intrusiveness noise levels for the project are summarised in Table 4-1.

Night 31 36 a. Day = 7:00am - 6:00pm; evening = 6:00pm - 10:00pm; night = 10:00pm - 7:00am.

4.2.2 Project Amenity Noise Levels

Project amenity noise levels aim to set a limit on continuing increases in noise levels from all industrial noise sources affecting a variety of receiver types; that is, the ambient noise level in an area from all industrial noise sources remains below recommended amenity noise levels.

The amenity assessment is based on noise criteria specific to land use and associated activities. The criteria relate only to industrial-type noise and do not include transportation noise (when on public transport corridors), noise from motor sport, construction noise, community noise, blasting, shooting ranges, occupational workplace noise, wind farms, amplified music/patron noise.

The amenity noise level aims to limit continuing increases in noise levels which may occur if the intrusiveness level alone is applied to successive development within an area.

The recommended amenity noise level represents the objective for total industrial noise at a receiver location. The project amenity noise level represents the objective for noise from a single industrial development at a receiver location.

To prevent increases in industrial noise due to the cumulative effect of several developments, the project amenity noise level for each new source of industrial noise is set at SdBA below the recommended amenity noise level.

The following exceptions apply to determining the project amenity noise level:

• For high-traffic areas the amenity criterion for industrial noise becomes the lAeq,perioo(trafficJ

minus 15dBA.

• In proposed developments in major industrial clusters.

• If the resulting project amenity noise level is lOdB or more, lower than the existing industrial noise level, the project amenity noise level can be set at lOdB below existing industrial noise levels if it can be demonstrated that existing industrial noise levels are unlikely to reduce over time.

• Where cumulative industrial noise is not a consideration because no other industries are present in, or likely to be introduced into the area, the relevant amenity noise level is assigned as the project amenity noise level for the development.

Amenity noise levels are not used directly as regulatory limits. They are used in combination with the project intrusiveness noise level to assess the potential impact of noise, assess mitigation options and determine achievable noise requirements.

@



The project amenity noise levels are calculated from the recommended amenity noise levels presented in Table 4-2.

Recommended amenity noise levels presented in Table 4-2 above represent the objective for total industrial noise at a receiver location. In the case of a single new noise source being proposed, the project amenity noise level represents the objective for noise from a single industrial development at the receiver location. This is calculated as the recommended amenity noise level minus SdBA.



Due to different averaging periods for the LAeq,1smin and lAeq,period noise descriptors, the values of project intrusiveness and amenity noise levels cannot be compared directly when identifying noise trigger levels i.e.; the most stringent values of each category. In order to make a comparison between descriptors, the NPfl assumes that the LAeq,1sm,n equivalent of an lAeq,period noise level is equal to the Ueq,1smin level plus 3dB.

Residential receivers near the Proposal are classified as being in a "suburban" noise amenity area. The project amenity noise levels for the Proposal are presented in Table 4-3.

4.2.3 Project Noise Trigger Levels

Table 4-4 below shows the project noise levels for sensitive receivers, with the project noise trigger levels shown in bold.

The oxygen vessel would be refilled by a tanker truck approximately every three weeks. The truck would typically arrive between midday and 2:00pm and would remain on site for 10 - 15 minutes. Due to the occasional nature of this activity, a 7 dBA allowance has been added to the acceptable noise level in accordance with "Fact Sheet C" of the NPfI.

4.2.4 Maximum Noise Trigger Levels

Noise sources at night occurring over a short duration have the potential to cause sleep disturbance despite complying with project noise trigger levels. The manufacturing facilities are intended to operate on a 24-hour basis as required. Therefore, maximum noise level events need to be considered for potential sleep disturbance.

The NPfI recommends that, where the night time LAmax receiver noise levels from a development exceeds 52 dBA or the RBL plus 15 dBA, whichever is the greater, then a more detailed assessment of potential sleep disturbance impacts is warranted. Table 4-5 presents the maximum noise trigger levels for the receivers identified in this assessment. These noise levels are typically addressed at the facade of potentially affected dwellings and should consider multiple storey dwellings.

Table 4-5 Maximum Noise Trigger Levels

All nearby residential 31 46

Maximum Noise Trigger Level

Receiver RBL {dBA) RBL + 15 dBA

Additionally, in instances where night time LAeq,1sm,n noise levels exceed 40 dBA or the prevailing RBL plus 5 dBA, whichever is the greater, then a detailed assessment of potential sleep disturbance impacts is warranted. Since the night time project noise trigger level is less than 40 dBA for all nearby receivers, compliance with these noise trigger levels will ensure that no further assessment of night time lAeq,1sm,n noise levels, with regard to sleep disturbance, would be required

4.3 Noise Prediction Methodology

Operational noise emissions from the site have been modelled using the CONCAWE noise prediction algorithm, as implemented in the "CadnaA" acoustic software. Factors that are addressed in the noise modelling are:

• Equipment noise level emissions and locations;

• Shielding from ground topography and structures;

• Noise attenuation due to geometric spreading;

• Ground absorption; and

• Atmospheric absorption.

4.4 Operational Noise Sources

The major noise sources associated with the Proposal are carpark movements, air conditioning units and the oxygen delivery truck. The sound power levels (SWLs) of the key operational noise sources are presented in Table 4-6.

Truck - 10 km/h 93 92 89 87 85 86 84 76 67 90

The detailed design of the mechanical plant is yet to be completed. Therefore, for the purposes of assessment, it has been assumed that each of the 23 new rooms would have a dedicated air conditioning unit, located at the eastern end of the building extension, as per the plans. The assumed sound power level of the air conditioning units, shown in Table 4-6, represents that of an air conditioning unit typically used in this application.

4.5 Assessment Scenarios

Noise assessment scenarios have been developed to represent typical worst-case receiver noise levels associated with the option of the Proposal and those associated with oxygen refilling.

4.5.1 Typical Operations

Typical worst-case operations would involve a combination of carpark movements and air conditioning units running.

As described above, it is assumed that 23 individual air conditioning units would be installed at the eastern end of the building extension. During typical worst case operations, it is assumed that all units would be operating.

The Proposal would establish 10 new car-parks at the eastern end of the building extension. For assessment purposes, it is assumed that 10 vehicle movements occur between the new carpark and the new site entrance on Wolsley Street. These movements could be arrivals, departures or a combination of both.

4.5.2 Oxygen Refilling

For assessment purposes, it is assumed that oxygen refilling would occur in parallel with the typical worst-case operations as described above. The truck would access the site via Wolsley Street and proceed to the new vessel location. Refilling of the vessel would take up to 15 minutes, during which time it is assumed that the truck engine would be turned off.

4.6 Assessment of Impacts

The following section presents the predicted noise levels at the most potentially affected sensitive receivers during the scenarios described above.

The predicted LAeq,1smin noise levels at the most potentially affected sensitive receivers during typical worst-case operation of the Proposal are presented in Table 4-7.

The results in Table 4-7 indicate that the predicted noise levels comply with the established project noise trigger levels at all receivers, except for RS where the predicted noise level exceeds the project noise trigger level by 3 dB in the evening and night time.

The predicted LAeq,1sm;n noise levels at the most potentially affected sensitive receivers during oxygen refilling are presented in Table 4-8.

4.7 Sleep Disturbance Assessment

The most likely sources of maximum noise events associated with the Proposal would be car doors closing and engines staring in the carpark.



Based on measurements previously conducted by Wilkinson Murray, the LAmax sound power level associated with typical maximum noise events in car parks is 96 dBA. The predicted LAmax noise levels at sensitive receivers associated with the night time use of the car park are presented in Table 4-9.

The predicted LAmax noise levels at receivers presented in Table 4-9 comply with the established maximum noise trigger levels at all receivers. Therefore, no further assessment of potential sleep disturbance impacts is warranted.

4. 7.1 Noise Mitigation

The preceding assessment has indicated the potential for operational noise levels to exceed the project noise trigger level at RS by 3 dB during typical worst-case operations in the evening and night time and by 2 dB during oxygen refilling.

Further analysis of the modelling results indicates that the predicted exceedances at RS are primarily due to vehicle movements on the new access to Wolsely Street. The boundary fence between the Proposal site and RS is a chain-link fence which provides no acoustic shielding.

Therefore, it is recommended that all or a portion of the fence is replaced with a fence of solid construction, such as lapped and capped timber or colorbond. The solid fence should be at least 2.1 metres in height and should extend from the eastern edge of the RS dwelling toward Wolsley Street as far as practicable.

Figure 4-1 shows the recommended location of the solid fence. Table 4-10 and Table 4-11 present the predicted operational noise levels, with the aforementioned solid fence, for typical worst-case operations and oxygen refilling, respectively. The results in Table 4-10 and Table 4-11 indicate compliance with the project noise trigger levels.

6 CONCLUSION

Development approval is being sought from Orange City Council for proposed additions and alterations to the existing Dudley Private Hospital, located at 261 March Street, Orange.

Wilkinson Murray Pty Limited has been engaged by Ramsay Health to conduct an operational noise impact assessment for the proposal. The assessment evaluates potential noise impacts associated with the operation of new and amended aspects of the site in general accordance with the Noise Policy for Industry (the NPfl).

The assessment has been conducted in general accordance with the NSW Noise Policy for Industry and has concluded that, subject to the establishment of a solid fence along a portion of the northern boundary of the site, noise levels associated with the operation of the Proposal comply with the established noise trigger levels at all times.
