3 PROPOSED DEVELOPMENT
3 . 1 D ev e lop men t S u m ma r y
The change of use proposal seeks to utilise the existing dwelling as a childcare premises by undertaking relatively minor internal and external building modifications and improvements and providing for sufficient car parking, whilst retaining the residential character of the building. Outdoor play spaces will be accommodated within the existing open space areas on the property. Input from the project acoustic consultant has confirmed the development will have no material impact on the existing amenity of the locality, and that any potential amenity impacts associated with noise can be readily managed within the site.
3 . 2 S i t e La y ou t & D e s ign
The proposed modifications to the existing dwelling are presented on the attached Development Plan set prepared by Studio 4 Building Design, including a Development Site Plan, Floor Plans and Elevations (Appendix A). As aforementioned, the proposed child care premises has been designed to accommodate up to 20 children and 3 full time staff members. This facility shall comprise a total of 303m2 of outdoor play space (in three separate areas to cater for different age groups) and three separate indoor play spaces (in addition to the functional indoor spaces, amenities and staffing spaces). Each of the play areas are compliant with the spatial requirements per child, as set out in the Child Care Services (Child Care) Regulations, 2006. Parking bays are provided within the front setback area, deriving access via a single crossover from Walkington Circle. The car parking area accommodates 5 car parking spaces, including one universal access bay. The entrance to the facility shall be via the existing front entry to the dwelling.
3 . 3 H o u r s o f Op er at i on & St a f f in g
The child care premises will operate from 7:30am to 5:30pm on weekdays only (Monday to Friday). The facility is proposed to accommodate a maximum of 20 children at any one time. The Child Care Services (Child Care) Regulations, 2006 set out the requirement for the number of staff required to manage a centre, based on the number of children (and age group demographic) accommodated. This centre will require a total of 3 staff members, in accordance with the following ratios:
Age Group Staffing Required Proposal
Children less than 24 months 1 staff member per 4 children 4 children 1 staff member
Children aged 24 to 36 months 1 staff member per 5 children 5 children 1 staff member
Children aged more than 36 months 1 staff member per 10 children 10 children 1 staff member
19 children* 3 staff members
Table 2 – Staffing Ratios
* This Application proposes a maximum of 20 children based on planning requirements. The Child Care Services (Child Care) Regulations, 2006 governs the number of children that may be enrolled at the facility based on the age of children and associated staffing ratios. The relative number of children enrolled within a particular age group may be subject to change .

4 PLANNING FRAMEWORK
4 . 1 C i t y o f K a rr at h a Loc a l P l an n in g S ch e me No . 8
The subject site is zoned ‘Urban Development’ under the City of Karratha Local Planning Scheme No. 8 (LPS 8) and is identified within Development Area 1 (DA 1). The site is also contained within the Airport Obstacle Height Limitation Area (SCA). Given no substantial development is proposed, the SCA is not relevant to this proposal. A Zoning Map, demonstrating the zoning of the site and surrounding locality, is included at Figure 2. DA 1 – Millars Well Bathgate Road – Area E is referenced in Appendix 5 of LPS 8 as being subject to the following special conditions: 1. Structure Plan adopted to guide subdivision, land use and development. 2. To provide for residential development and recreation. The DA 1 – Millars Well Bathgate Road – Area E Development Plan (Structure Plan) was endorsed by Council in 2004 and designates the subject site as ‘Residential (R12.5)’. There are no specific land use controls imposed by the Structure Plan applicable to the proposal.
Figure 2 – LPS 8 Zoning Map (Subject Site outlined in red) The land use definition relevant to this application is defined within LPS 8 as follows:
Child Care Premises - has the same meaning as in the Community Services (Child Care) Regulations 1988.
The Community Services (Child Care) Regulations, 1988 define a child care premises as:
P R O P O S E D C H I L D C A R E P R E M I S E S Lot 221 (No.3) Walkington Circle, Millars Well 5 | Page
…premises specified in a licence or permit as premises in which a child care service may be provided.
‘Child Care Premises’ is included under the Health, Welfare and Community Services category in the Zoning Table and is an ‘A’ use in the Residential zone, meaning the use is not permitted unless the local government has exercised its discretion by granting development approval after giving special notice in accordance with Clause 64 of the deemed provisions. Appendix 3 – Car Parking Requirements identifies car parking for a child care premises should be provided at a ratio of 1 car bay per every 10 children plus one car bay per employee. The car parking requirements for the proposed child care premises have been satisfied. City staff have confirmed as part of pre-lodgement consultation there are no separate Local Planning Policies relating to the assessment of child care premises.
4 . 2 R e st r i c t i ve Co ve n an t
A copy of the Certificate of Title, Deposited Plan and Restrictive Covenant registered on the title of Lot 221 is included at Appendix B. The Restrictive Covenant does not limit the proposed use of the lot for a childcare premises, on the basis it was only enforceable until 1 July 2015 (and hence has now expired) and in any case was only for the purpose of imposing building and land use controls that are not relevant to this application.
P R O P O S E D C H I L D C A R E P R E M I S E S Lot 221 (No.3) Walkington Circle, Millars Well 6 | Page
5 MANAGEMENT CONSIDERATIONS
5 . 1 C a r Pa r k in g a n d T r af f i c M an ag em en t
Five (5) car bays are proposed to service the childcare premises, including 2 visitor bays (at a ratio of 1 bay/10 children) and 3 staff bays (at a ratio of 1 bay/staff member). One of the staff bays is an accessible bay which will be provided in accordance with clause D3.5 d) of AS2890.6. All car bays have been designed to ensure cars can safely and efficiently enter and exit the car park area in forward gear. The overall traffic generated by the facility is estimated to be in the order of 45-50 vehicle trips per day, which represents only a minor increase in the overall traffic generated by existing dwellings along Walkington Circle. The location of the site at the start of Walkington Circle (and the first cross-over encountered after the intersection with Bathgate Road) means traffic will not need to continue along Walkington Circle past other dwellings to access the proposed childcare premises. The proposed facility is otherwise easily accessible from Bathgate Road which connects to Bayview Road to the north and Dampier Highway to the south.
5 . 2 A c ou st i c M an a g eme n t
The design of this development has been prepared having regard to the locality, as well as the single existing sensitive land use (dwelling) directly adjoining the development on its eastern boundary. An Environmental Acoustic Assessment (EAA) has been prepared by Herring Storer in support of this application, and is attached at Appendix C. The intent of the EAA is to assess and address the outgoing noise emissions from the Child Care Premises to ensure the development is able to comply with the Environmental Protection (Noise) Regulations 1997, thereby ensuring the acoustic amenity of the site is protected. The EAA considers the potential noise sources occurring within this development as being car doors closing and children playing in outdoor play areas. The EAA confirms noise received at the neighbouring premises from car doors closing and children playing in the outdoor areas would, with the existing boundary fencing, comply with the requirements of the Environmental Protection (Noise) Regulations 1997, during the proposed hours of operation. It is anticipated that a condition of approval would require a Noise Management Plan to be prepared and approved by the City of Karratha, and complied with in perpetuity.
5 . 3 W a st e M an a g em en t
The proposed development includes a bin store area which has been designed to visually screen bins provided to accommodate any general waste and recyclable materials generated by the facility. It is anticipated that the development would utilise the City’s residential waste management services for collection of all bins from the Walkington Circle verge.
5 . 4 L an d s c ap in g
Conceptual landscaping detail is included as part of the development plans at Appendix A, which illustrates the proposed landscaping treatments of the front setback area and Walkington Circle verge, including proposed street trees, plantings within garden beds and within planter boxes. Proposed landscaping will assist in maintaining the residential amenity of the site.

6 CONCLUSION
This Development Application for a change of use has provided the relevant details and supporting rationale for the development of a child care premises at Lot 221 (No.3) Walkington Circle, Millars Well. Approval of this proposal would allow for the operation of a child care premises designed to accommodate a maximum of 20 children and 3 staff members within the existing dwelling. This submission demonstrates that the servicing and management requirements for the facility, including parking, acoustic output and waste can adequately be met. The submission has also demonstrated that the proposal is compliant with Local Planning Scheme No. 8. The proposed use of the existing dwelling as a child care premises can readily be accommodated on the subject site without having an adverse effect of the residential amenity of the locality in terms of traffic generation, noise or visual impact and will contribute to the provision of an essential community service within the City of Karratha. In view of the attributes of this proposal as provided within this report, the associated Development Plans and supporting acoustic report, it is respectfully requested that the City of Karratha approve this child care premises at Lot 221 (No. 3) Walkington Circle, Millars Well. Should you have any further queries or require any additional information to support this proposal, please do not hesitate to contact David Maiorana at this office.

Herring Storer Acoustics Our Ref: 26941‐2‐20358 1
1. INTRODUCTION
Herring Storer Acoustics were commissioned to undertake an acoustic assessment of noise emissions associated with the proposed day care centre to be located at 3 Walkington Circle, Millars Well (Karratha).
The report considers noise received at the neighbouring premises from the proposed development for compliance with the requirements of the Environmental Protection (Noise) Regulations 1997. This report considers noise emissions from children playing within the outside play areas of the centre.
We note that from information received from DWER, the bitumised area would be considered as a road, thus noise relating to motor vehicles is exempt from the Environmental Protection (Noise) Regulations 1997. We note that these noise sources are rarely critical in the determination of compliance. However, as requested by council and for completeness, they have been included in the assessment, for information purposes only.
For information, a plan of the proposed development is attached in Appendix A.
2. SUMMARY
Noise received at the neighbouring premises from children playing in the outdoor areas would, with the existing boundary fencing, comply with the requirements of the Environmental Protection (Noise) Regulations 1997, for the day period. It is noted that noise associated with car movements and car starts are exempt from complying with the Regulations. However, noise emissions from car doors is not strictly exempt from the Regulations. Noise received at the neighbouring residences from these noise sources would comply with the Regulatory requirements, with boundary fencing, as shown on the plans attached in Appendix A. Thus, noise emissions from the proposed development, would be deemed to comply with the requirements of the Environmental Protection (Noise) Regulations 1997 for the proposed hours of operation, with the existing boundary fencing.
3. CRITERIA
The allowable noise level at the surrounding locales is prescribed by the Environmental Protection (Noise) Regulations 1997. Regulations 7 & 8 stipulate maximum allowable external noise levels. For highly sensitive area of a noise sensitive premises this is determined by the calculation of an influencing factor, which is then added to the base levels shown below in Table 3.1. The influencing factor is calculated for the usage of land within two circles, having radii of 100m and 450m from the premises of concern. For other areas within a noise sensitive premises, the assigned noise levels are fixed throughout the day, as listed in Table 3.1.

Note: LA10 is the noise level exceeded for 10% of the time. LA1 is the noise level exceeded for 1% of the time. LAmax is the maximum noise level. IF is the influencing factor.
Under the Regulations, a highly sensitive area means that area (if any) of noise sensitive premises comprising –
(a) A building, or a part of a building, on the premises that is used for a noise sensitive purpose; and
(b) Any other part of the premises within 15 m of that building or that part of the building.
It is a requirement that received noise be free of annoying characteristics (tonality, modulation and impulsiveness), defined below as per Regulation 9.
“impulsiveness” means a variation in the emission of a noise where the difference between LApeak and LAmax(Slow) is more than 15 dB when determined for a single representative event;
“modulation” means a variation in the emission of noise that –
(a) is more than 3 dB LAFast or is more than 3 dB LAFast in any one‐third octave band;
(b) is present for more at least 10% of the representative assessment period; and
(c) is regular, cyclic and audible;
“tonality” means the presence in the noise emission of tonal characteristics where the difference between –
(a) the A‐weighted sound pressure level in any one‐third octave band; and
(b) the arithmetic average of the A‐weighted sound pressure levels in the 2 adjacent one‐third octave bands,
is greater than 3 dB when the sound pressure levels are determined as LAeq,T levels where the time period T is greater than 10% of the representative assessment period, or greater than 8 dB at any time when the sound pressure levels are determined as LASlow levels.
Herring Storer Acoustics Our Ref: 26941‐2‐20358 3
Where the noise emission is not music, if the above characteristics exist and cannot be practicably removed, then any measured level is adjusted according to Table 3.2 below.
TABLE 3.2 ‐ ADJUSTMENTS TO MEASURED LEVELS
Where tonality is present Where modulation is present Where impulsiveness is present
+5 dB(A) +5 dB(A) +10 dB(A)
Note: These adjustments are cumulative to a maximum of 15 dB.
For this development, the closest neighbouring residences of concern to the proposed development, are located around the development. An aerial of the area and neighbouring residences are shown below as Figure 01.
FIGURE 01 – NEIGHBOURING LOTS
At the neighbouring residences, as shown above, the influencing factor has been determined to be 0 dB. Thus, the assigned noise levels would be as listed in Table 3.3.

4. PROPOSAL
From information supplied, we understand that the child care centre normal hours of operations would be between 07:30am to 05:30pm, Monday to Friday (closed on public holidays). It is understood that the proposed childcare centre will cater for a maximum of 19 children; with the following breakdown : 0 – 24 months 4 places 24 – 36 months 5 places 36+ months 10 places
5. MODELLING
To assess the noise received at the neighbouring premises from the proposed development, noise modelling was undertaken using the noise modelling program SoundPlan.
Calculations were carried out using the DWER’s weather conditions, which relate to worst case noise propagation, as stated in the Department of Environment Regulation “Draft Guidance on Environmental Noise for Prescribed Premises”. These conditions include winds blowing from sources to the receiver(s). Calculations were based on the sound power levels used in the calculations are listed in Table 5.1.
TABLE 5.1 – SOUND POWER LEVELS
Item Sound Power Level, dB(A)
Children Playing 83 (per 10 children)
Car Moving in Car Park 79
Car Starting 85
Door Closing 87
Notes :
1 Given the number and breakdown of children, acoustic modelling of outdoor play noise was made, based on 20 children playing within the outdoor play areas at the one time, utilising 2 groups of 10 children sound power levels distributed as plane sources, with one group within the toddlers area and another within the Pre‐Kindy Area.
2 Existing boundary fences.
3 Noise modelling was undertaken to a number of different receiver locations for each of the neighbouring residences. However, to simplify the assessment, only the noise level in the worst case location for each location have been listed.
6. ASSESSMENT
The resultant noise levels at the neighbouring residence from children playing outdoors are tabulated in Table 6.1. From previous measurements, noise emissions from children playing does not contain any annoying characteristics. Noise emissions from both outdoor play and the mechanical services needs to comply with the assigned LA10 noise levels.

With regards to noise associated with cars within the parking area, resultant noise levels are tabulated in Tables 6.2 and 6.3. It is noted that noise emissions from a moving car being an LA1 noise level, with noise emissions from cars starting and doors closing being an LAmax noise level.
Based on the definitions of tonality, noise emissions from car movements and car starts, being an LA1 and LAMax respectively, being present for less than 10% of the time, would not be considered tonal. Thus, no penalties would be applicable, and the assessment would be as listed in Table 6.2 (Car Moving) and Table 6.3 (Car Starting). However, noise emissions from car doors closing could be impulsive, hence the +10dB penalty has been included in the assessment.

[ ] Includes +10 dB(A) penalty for impulsiveness. Tables 6.4 to 6.8 summarise the applicable Assigned Noise Levels, and assessable noise level emissions for each identified noise.

7. CONCLUSION
Noise received at the neighbouring residential premises from children playing in the outdoor play area would, with the existing boundary fencing, comply with the requirements of the Environmental Protection (Noise) Regulations 1997 for the day period. It is noted that noise associated with cars movements and cars starting are exempt from complying with the Regulations. However, noise emissions from car doors is not strictly exempt from the Regulations. Noise received at the neighbouring residences from these noise sources would comply with the Regulatory requirements, with existing boundary fencing. Thus, noise emissions from the proposed development, would be deemed to comply with the requirements of the Environmental Protection (Noise) Regulations 1997 for the proposed hours of operation, with the inclusion of the mitigation as outlined above.
