CHAPTER 1

1. INTRODUCTION

1.1 Colston Budd Hunt and Kafes Pty Ltd has been commissioned by Benedict

Industries to prepare a report examining the traffic implications of proposed

modifications to the operation of the existing Sandy Point quarry, located on

Heathcote, Sandy Point. The site location is shown in Figure 1.

1.2 The existing quarry operates six days a week and has been the subject of a

number of approvals:

o Planning Consent 900/67 issued 14 July 1967- No limit on extraction;

o Previous EPL licence limit on extraction, crushing, grinding and milling

200,000 tonnes per annum.

1.3 lt is proposed to import material (some 180,000 to 240,000 tonnes per annum)

into the quarry to be processed into a substitute for naturally quarried materials.

This would bring the cumulative activity to some 380,000 to 440,000 tonnes per

annum.

1.4 This report assesses the traffic implications of the proposed development through

the following chapters:

o Chapter 2- describing the existing conditions; and

o Chapter 3- assessing the transport implications of the proposed

development.



CHAPTER2

2. EXISTING CONDITIONS

Site Location and Road Network

2.1 The existing quarry is located on the eastern side of Heathcote Road, Sandy Point

(with the site access located approximately one kilometre south of St George

Crescent). The site has access from Heathcote Road with all turning movements

permitted. The site access is a sealed two lane road with a wide sealed area

adjacent to Heathcote Road. Within the site, gravel roads and dirt tracks provide

access to the various quarry areas. A weighbridge and associated facilities are

located several hundred metres within the site. Employees generally park in an

informal car park located adjacent to the weighbridge. The current quarry

operates six days a week with trucks collecting extracted material between 6.00

am and 4.00 pm.

2.2 Heathcote Road adjacent to the site is a two way rural road with one traffic lane in

each direction and unsealed shoulders. lt has a posted speed limit of 80 km/h .

Sight lines from the site access to the south along Heathcote Road are good being

500 metres. To the north, Heath cote Road bends to the northwest, and sight

lines are some 150 metres. Heathcote Road is an arterial road that connects

Liverpool with Sutherland.

Traffic Flows

2.3 In order to gauge traffic conditions, counts were undertaken during Tuesday

morning (6.30am to 9.30am) and afternoon (3 .00pm to 6.30pm) in late October

CHAPTER 2

2011 at the intersection of the site access and Heathcote Road. The results of

the surveys are displayed in Figures 2 and 3 and found that:

o Heathcote Road carries some 1 ,800 vehicles per hour (two way) in the peak

periods; and

o the site generated some 15 trucks (two way) in the morning peak hour. In the

afternoon peak hour the site generated some 5 trucks (two way).

2.4 In order to assess the cumulative impacts of quarry and ancillary operations,

particularly in the morning and afternoon peak periods, a review of truck

movements associated of quarry operations (based on the running sheet) was

undertaken. On the Tuesday of the traffic surveys (October 2011) it was found

that there were some 100 truck movements (50 in/50 out) between 6.00am and

3.00pm. The surveys found that over 90% of trucks arrived from or departed to

the north along Heathcote Road . Based on five and half days a week, 50 weeks

per year operation, with loads of 32 tonnes per truck, this is equivalent of an

extraction of 440,000 tonnes per year.

Intersection Operations

2.5 The capacity of the road network is largely determined by the capacity of its

intersections to cater for peak period traffic flows. The intersection of the site

access and Heathcote Road has been analysed using the SIDRA program. SIDRA

simulates the operations of intersections to provide a number of performance

measures. The most useful measure provided is average delay per vehicle

expressed in seconds per vehicle. Based on average delay per vehicle, SI ORA

estimates the following levels of service (LOS) :

CHAPTER 2

o For traffic signals, the average delay per vehicle in seconds is calculated as

delay/(all vehicles), for roundabouts the average delay per vehicle in seconds is

selected for the movement with the highest average delay per vehicle,

equivalent to the following LOS:

0 to 14 "A" Good

15 to 28 "B" Good with minimal delays and spare capacity

29 to 42 "C" Satisfactory with spare capacity

43 to 56 "D" Satisfactory but operating near capacity

57 to 70 "E" At capacity and incidents will cause excessive

delays. Roundabouts require other control mode.

> 70 I! F." Unsatisfactory and requires additional capacity

o For give way and stop signs, the average delay per vehicle in seconds is

selected from the movement with the highest average delay per vehicle,

equivalent to following LOS:

0 to 14 -"A" Good

15 to 28 "B" Acceptable delays and spare capacity

29 to 42 "C" Satisfactory but accident study required

43 to 56 "D" Near capacity and accident study required

57 to 70 "E" At capacity and requires other control mode

> 70 "Fn Unsatisfactory and requires other control mode

2.6 lt should be noted that for roundabouts, give way and stop signs, in some

circumstances, simply examining the highest individual average delay can be

misleading. The size of the movement with the highest average delay per vehicle

2.7


CHAPTER2

should also be taken into account. Thus, for example, an intersection where all

movements are operating at a level of service A, except one which is at level of

service E, may not necessarily define the intersection level of service as E if that

movement is very small. That is, longer delays to a small number of vehicles may

not justify upgrading an intersection unless a safety issue was also involved .

The SI ORA analysis found that the Heathcote Road and the site access intersection

operates with average delays of some 38 seconds per vehicle in the peak periods.

This represents level of service C, a satisfactory level of intersection operation.

Outside of peak periods delays are less as traffic flows are lower along Heathcote

Road.

3. IMPLICATIONS OF PROPOSED DEVELOPMENT

3.1 lt is proposed to import material (some 180,000 to 240,000 tonnes per annum)

into the quarry to be processed into a. substitute for naturally quarried materials.

This would bring the cumulative activity to some 380,000 to 440,000 tonnes per

annum. To accommodate the importation of material, a number of changes to

stockpiling and blending of material are proposed. These are shown on Figure 4 . .

This chapter assesses the implications of the proposed development through the

following sections:

o parking provision;

o access and internal layout;

o traffic effects; and

o summary.

Parking Provision

3.2 Parking for employees will be accommodated in the informal parking area located

in the vicinity of the weigh station. There is ample room to accommodate parking

for any additional employees within the 38.12 ha site.

Access and Internal Layout

3.3 Vehicular access will be maintained from Heathcote Road via the existing sealed

access road. Within the site, new roads will be constructed as required to access

the new activity areas. These new roads will be designed to accommodate the

design vehicles that will use them (trucks or loaders).

Traffic Effects

3.4 lt is proposed to import up to 240,000 tonnes of material per year and mix this

with 200,000 tonnes extracted, which will then be transported off site (tota.l of up

to 440,000 tonnes). lt is understood that a proportion of trucks (some 50%)

bringing material into the site will depart with a load of blended material. Based

on five and half days a week, 50 weeks a year operation and 32 tonne load trucks,

the following number of truck movements are estimated:

o trucks bringing material to the site- 28 trucks per day;

o trucks departing empty (after bringing material in) - 14 per day; ·

o trucks departing with material (after bringing material in) - 14 per day;

o trucks arriving empty to collect material - 9 per day; and

o trucks departing with material (after arriving empty) - 9 per day.

3.5 Thus the proposed change in operation will result in an average of 7 4 truck

movements per day (37 in/37 out) . Based on the survey of existing quarry

operations some 15% of daily truck movements occur in the weekday morning

peak hour and some 5% in the weekday afternoon peak hour. Using these rates

peak mur traffic generation would total some 12 and 4 Vehicles per hour in

weekday morning and afternoon peak hours respectively.

3.6 lt is likely that material being brought to the site will be more evenly split between

east and west compared to the distribution of material (mainly to/from the west).

On this basis the increase in traffic movements on Heathcote Road as a result of

the proposed development would be some 5 to 1 0 vehicles per hour (two way) in

the weekday morning peak hour, with a smaller increase in the weekday

ATTACHMENT

afternoon peak hour. These are minor increases (one vehicle every 7 to 15

minutes) and would not change the operation of traffic flows along Heathcote

Road (which carries some 1 ,800 vehicles per hour in the weekday morning and

afternoon peak hours).

3.7 The operation of the Heathcote Road/site access intersection was reanalysed

using SIDRA with development traffic in place. The analysis found that it operates

with average delays of some 39 seconds per vehicle in the peak periods. This

represents level of service C, a satisfactory level of intersection operation.

Outside of peak periods delays are less, as traffic flows are lower along Heathcote

Road.

3.8 As noted in Chapter 2 sight lines at the access to Heathcote Road are some 500

metres to the south and some 150 metres to the north. AS2890.2-2002 suggests

a minimum sight distance requirement of 111 metres for an 80 km/h speed

environment. Thus the available sight lines at the site access satisfy the

requirements of AS2890.2-2002.

Summary

3.9 In summary, the assessment of the traffic effects of the proposed development has

found that it would result in a minor increase in traffic generation. The operation

of the site access would continue to operate at a satisfactory level of service in the

peak periods. Sight lines comply with the requirements of AS2890.2-2002.

3. We have reviewed the report and note that there is miscalculation in the number of trucks arriving empty to collect blended

material. This was estimated to be 9 trucks per day and should have been 36. This increases the daily truck movements per day from 74 to 128 (64 in/64 out). Based on the survey of existing quarry operations some 15% of daily truck movements occur in the weekday morning peak hour and some 5% in the weekday afternoon peak hour. Using these rates, peak hour traffic generation would total some 20 and 6 vehicles per hour in weekday morning and afternoon peak hours respectively. The response to traffic matters is based on the updated estimate of additional truck movements.

4. Thus the proposed modifications to the existing Sandy Point Quarry will result in a only a minor increase in traffic movements (some 6 to 20 truck movements per hour, two-way, in the weekday morning and afternoon peak hours). Such a minor increase (one truck every 3 to 10 minutes) will not change the operation of Heathcote Road (which carries some 1,800 vehicles per hour (two way) in the peak periods, or the operation of the site access on Heathcote Road.
