3. THE PROPOSAL

It is proposed to refurbish the existing dwelling to provide a child care centre for 29

children.

It is understood from discussions with the applicant that the before and after school

care service operates between 7 am and 9 am and between 3 pm and 6 pm on

weekdays. The child care centre is not proposed to operate on weekends. A total of

four support staff will be provided for the child care centre.

It is proposed to provide a total of eight car parking spaces, inclusive of a disabled

parking space, of which three spaces will be allocated to staff and five spaces

allocated to visitors, inclusive of an accessible space. In addition, two bicycle spaces

are proposed to be provided to encourage staff to cycle to the development.

The layout of the proposed access and car parking areas are shown in Attachment A.

4. CAR PARKING CONSIDERATIONS

4.1 Car Parking Requirements

The car parking requirements for the proposed land use components are set out in

Blacktown’s DCP (2015), specifically Part A, Section 6.3 (Table 1).

Reference to Blacktown’s DCP (2015) indicates that the car parking requirements for

the proposed child care centre are summarised as:

• 1 space per employee, plus

• 1 space per 6 children or part thereof for parents and visitors.

Further, reference to the Building Code of Australia indicates that, for a child care

centre there is a requirement to provide one disabled parking space, which is satisfied

by the proposed provision of a disabled bay.

Application of the above parking rates results in a car parking requirement of nine

spaces inclusive of one disabled space.

Based upon the on-site parking provision of eight spaces and development’s car

parking requirement for nine spaces, the proposed development has a car parking

deficiency of one space.

Reference to the results of the parking surveys (Section 2.,3) indicates that there are

ample available on-street spaces to accommodate the development’s car parking

deficiency of one space.

4.2 Bicycle Parking Requirements

There are no specific bicycle parking requirements for the child care centre as set out

in Blacktown’s DCP (2015), specifically Part A, Section 6.3 (Table 1).

7

Notwithstanding the above, to encourage staff and visitors to the child care centre

to arrive by sustainable means, it is recommended that two bicycle spaces be

located in the front of the site.

4.3 Motorcycle Parking Requirements

There are no motorcycle parking requirements for the child care centre as set out in

Blacktown’s DCP (2015), specifically Part A, Section 6.3.

4.4 Car Park Layout

4.4.1 Dimensions of car accommodation

The visitor parking bays in the car park have been provided at a width of 2.6 m and a

length of 5.4 m with an adjacent aisle width of at least 5.8 m. The staff parking bays

have been provided at a width of 2.6 m and a length of 5.4 m.

Further, wheels stops are proposed to be provided in the easternmost visitor spaces

and the westernmost staff spaces to regulate parking activity within these spaces.

The accessible bay has been provided at a width of 2.4 m with the adjacent

shared/manoeuvring space provided at a width of 2.4 m with a length of 5.4 m and

an aisle width in excess of 5.8 m and a bollard is located centrally within the shared

space at an offset a distance of 800 mm from the edge of the accessway, which

accords with the Australian Standards, AS 2890.6:2009.

Offset clearances of 300 mm have been provided adjacent to any bays located next

to end walls as required by AS 29890.1:2004. In addition, while a blind aisle extension

of 1 m has been provided at the southern end of the accessway in accordance with

AS 2890.1:2004, the swept path assessment indicates that motorists can safely

enter/exit the end bays.

It is recommended that the staff spaces are linemarked yellow with appropriate

signage stating ‘reserved – child care staff parking only’, visitor parking bays are

recommended to be signposted and linemarked appropriately.

4.4.2 Access to/from car spaces

The swept paths of vehicles entering and exiting the respective car spaces on the

development site have been assessed with the use of the AutoTURN computer

software for a B85 car.

The analysis, which is shown in Attachment B indicates that to enable a motorist to

safely access the on-site spaces, manoeuvre from the spaces to then exit from the

car parking spaces in a forward manner to Maslin Crescent.

4.4.3 Width of internal access

Reference to the layout plans indicate that the width of the access to the car park is

5 m which accords with the requirements stipulated in the Australian Standard, AS

2890.1:2004.

8

4.4.4 Sight lines for exiting motorists

To ensure maximum sight lines are provided for motorists exiting from the

development’s access and to pedestrians walking along the south side of Bungalow

Road, a triangular area measuring 2 m along the property boundary from the edge

of the driveway access (to the south) and 2.5 m along the access from the property

boundary, it is recommended that the sight line triangles to the immediate west and

east of the crossover at the boundary line contain low level ground cover (0.3 m max

height).

The requirement to provide sight line triangles for pedestrian safety is stipulated in

Figure 3.3 of the Australian Standard, AS 2890.1:2004.

Reference to the layout plans indicate that clear sight line triangles have been

provided on either side of the accessway. Further, any obstructions within the sight

line triangles such as vegetation or letter boxes, should have a height less than 900

mm.

5. OTHER

5.1 Commercial vehicles

Discussions with the applicant indicate that deliveries associated with the child care

would typically be undertaken in a small van during the off-peak periods, that is,

between the peak drop off/pick up time periods.

These vehicles can be accommodated within the car park. Deliveries are to be

restricted to the time periods between the drop off/pick up time periods, that is

between 9.30 am and 3 pm on weekdays to minimise any potential conflict with

parents arriving to drop off/pick up children.

5.2 Refuse

The refuse bins are currently stored on the west side of the child care centre. The bins

would be serviced by a private contractor in a 6.4 m Single Rigid Vehicle (SRV). An

example of a 6.4 m refuse truck is shown in Attachment D.

The swept paths of a refuse truck entering and exiting the development site have

been assessed with the use of the AutoTURN computer software for a 6.4 m truck.

The analysis, which is shown in Attachment E indicates that to enable a refuse truck

can safely access the on-site car park, manoeuvre on-site to then exit from the car

park in a forward manner to Maslin Crescent.

To minimise the potential for conflict with parents dropping off/picking up children, it

is recommended that the refuse bins are serviced outside of the child care centre’s

operating times.

6. TRAFFIC IMPACT

The anticipated traffic generation for the proposed child care centre can be

determined based upon case study survey data documented in the RTA NSW ‘Guide

to Traffic Engineering Developments’ (October 2002), which states that, for long day

care centres, the traffic generation rates correspond to 0.8 vehicle trips per child

during the morning drop off period, (7 am to 9 am) and a traffic generation rate of

0.7 vehicle movements per child during the late afternoon pick up period (4 pm to 6

pm).

Application of the traffic generation rates to the proposed development indicates

that, during the am peak hour, there will be around 24 vehicle movements (12

entry/12 exit movements) and during the pm peak hour, there will be around 20

vehicle movements (10 entry/10 exit movements).

The level of traffic generated by the child care centre could be adequately

accommodated along Maslin Crescent without representing an adverse impact

upon the amenity of the area.

7. CONCLUSIONS AND RECOMMENDATIONS

Having regard to the above, it is concluded that:

• The proposed the development has a car parking deficiency of one space;

• The results of the parking surveys (Section 2.,3) indicates that there are ample

available on-street spaces to accommodate the development’s car parking

deficiency of one space; and

• Traffic generated by the parents and staff will be minimal and is not expected

to adversely impact upon the safety or operation of the surrounding road

network.

Further, it is recommended that:

• the staff spaces are linemarked yellow with appropriate signage stating

‘reserved – child care staff parking only’, visitor parking bays be signposted and

linemarked appropriately;

• the refuse bins are serviced outside of the child care centre’s operating times;

• deliveries are to be restricted to the time periods between the drop off/pick up

time periods, that is, between 9.30 am and 3 pm on weekdays; and

• any obstructions within the sight line triangles such as vegetation or letter boxes,

should have a height less than 900 mm.
