Bankwest Stadium - Flood Emergency Response Plan 1

1 INTRODUCTION

1.1 BACKGROUND

VenuesLive Pty Ltd is taking over

management of the Bankwest Stadium, due to

finish construction in early 2019. The stadium

is located on O’Connell Street Parramatta, next to the Parramatta River, and has been

previously known as Parramatta Stadium.

The Stadium will seat 30,000 spectators,

include five levels of premium, corporate and

function spaces, and incorporate a range of

food and beverage outlets. The stadium will

predominately cater for sporting and

community events but will also cater for

concerts and functions.

Before operations can commence, a Flood

Emergency Response Plan (FERP) must be

completed and implemented as a condition of

the development approval (DA condition

D4.e).

To satisfy the condition, the FERP must:

Address evacuation, emergency access, flood warning and awareness, and refuge requirements within the site and any other relevant matters

Be based on the flood levels supplied by Council and any additional local flood and flow path modelling that may be required

Be prepared in consultation with the Council, the NSW State Emergency Services and NSW Fire and Rescue

Be fully operational prior to the commencement of the use and must be maintained in operation perpetually.

VenuesLive engaged Molino Stewart to

prepare this FERP to meet the above listed

requirements.

In addition to this, while the objective of the

consent condition is the protection to life,

VenuesLive is also concerned about flood risks

to property and profits. As such the FERP

includes measures and actions to protect the

facility itself, ensuring flood damage and

associated recovery time is minimised.

1.2 SITE DETAILS

1.2.1 Locality

The stadium is located in Parramatta, between

O’Connell Street and the Parramatta River, north-west of the Marsden Weir. It is located

on the parcels previously occupied by the

demolished Parramatta Stadium and the

Parramatta Pool.

It is bounded by the Parramatta Leagues Club

and Eels Place to the north, O’Connell Street to the east, the Parramatta River to the south,

the Old Kings Oval to the south-west, and the

Parramatta River to the west and north-west

(Figure 1).

1.2.2 Site Layout

The stadium will include six levels, namely:

L00 – Service level, located at a level of 9.12m AHD (Figure 2). L00 will include the playing field, a series of rooms and facilities located along the western side of the site, and four access tunnels connecting the pitch either directly to the outdoor area east of the stadium (i.e. the south east and north east tunnels), or to the indoor area along the western side of the site. Specifically, the rooms and facilities mentioned above will include:

- The players and officials area, with lockers, showers, warm up space, medical and physio rooms, coaching rooms, and press conference room

- A loading dock at the south-western corner, accessed via a road running along the southern end of the site to O’Connell Street

- Media rooms and facilities

- Kitchen an catering rooms and equipment

- Staff rooms and facilities (lockers, uniform store, briefing rooms, communication facilities, computer room, DAS rooms, offices)

- Security rooms (i.e. security staff offices, breakout room, cash room)

- Critical facilities, including the generator and tank room, main

2 VenuesLive

switch room, waste management rooms, fire pump and valve room, air circulation room

- Storage space.

L01 - Concourse Level, located at a level of 14.67m AHD (Figure 3). This level includes a free flow walkway running along the south, east and north perimeter of the stadium and providing access to the seating area, as well as to toilet facilities, cafes and entry/exist gates. The western part of the concourse is gated and includes the VIP area with related facilities and function rooms.

It should be noted that the ground level at all the entry/exit gates along the northern, western and eastern side of the stadium are about at the same level of the Concourse level (i.e. a14.67m AHD), the gates on the southern and south eastern side of the stadium have external stairs going down to the level of L00 (i.e. 9.12m AHD).

L02 – the Club Level, at a level of 20.07m AHD. This level’s footprint, as well as all the levels above, occupies only the western part of the site. L02 includes rooms and facilities for the Directors’ Club. It can be accessed from the Concourse level via stairs or lifts.

L03 – Suite Level, located at a level of 24.57m AHD, L03 occupies the same footprint as the Club Level. L03 includes 26 suites with access to private terraces overlooking the pitch. It also includes a kitchen area, and the executive offices.

L04 and L05 - the Media Level and Media Roof level, located at a level of 29.07m AHD and 33.57m AHD respectively, including a camera deck, commentary rooms and additional suites.

L06 – Roof Level, at a level of 33.57 m AHD.

The open seating area will surround the

playing field and extend from Level L00 (the

playing field level) up to level L05.

Figure 4 and Figure 5 show the stadium elevations.

The site will incorporate a stormwater drainage

system collecting rainwater falling over the

whole footprint of the site (including the pitch

and the roof) and discharging to the

Parramatta River via the exiting stormwater

drainage network.

1.2.3 Access

The stadium will be accessible via O’Connell Street either by car or on foot. There will be

two access driveways, north and south of the

stadium, leading to three car parking areas,

located north, west and south of the stadium.

The southern car park is not part of the Bank

West Stadium site. Part of the southern car

park is operated by Parramatta Park Trust and

the remainder operated by Parramatta Council.

Nevertheless, it is expected that the southern

car park will be available to the stadium

patrons during each event. The capacities of

the car parks are:

North - 292

West -187

South- 348

Total – 827

It is assumed that the large majority of patrons

will access the site on foot and will arrive in

Parramatta by public transport (bus, train or

light rail) or drive and park remote from the site

(street parking to the north and east or parking

stations in Parramatta CBD). The western car

park will be predominantly used by sport

players and performers, support staff, media

and suppliers. The northern car park will

accommodate VIP patrons and corporate

patrons with access to suites.

1.2.4 Topography

The overall topography of the site is sloping in

a north-west to south-east direction, however it

has been significantly altered locally by cut and

fill operations associated with the construction

works. The highest topographical level is just

below 15m AHD nearby the River, at the north-

western end of the site, while the lowest point

is in the southern car park at a level of 6.7m

AHD.

The stadium will be built so that the northern

end will have level L01 at ground level, while

the south part will have level L00 at ground

level (Figure 4 and Figure 5)

Figure 6 shows the as-built contour line

corresponding to 14m AHD, which is just


above the reach of floodwaters in a Probable

Maximum Flood (PMF).

1.2.5 Operation

The stadium will host two types of activities:

Events (i.e. activities utilising the playing field). It is anticipated that the stadium will host between 40 and 50 events per year with the number of patrons ranging between 10,000 and 30,000. These will generally be sports competitions, during which patrons will occupy the seating area, the concourse level and the suites at the upper levels. Media will occupy the media areas and most other areas within the stadium will be used during these events.

In addition to sport events there might be up to two music concerts per year, with up to 40,000 patrons each. In music concerts, the northern part of the seating area will be behind the stage and will have no patrons in it, resulting in a maximum of 25,000 patrons in the seating areas. However, there will be up to 15,000 patrons on the pitch at level L00.

There would be minimal vehicles in the stadium for events (less than 10) but the car parks around the perimeter of the stadium are expected to be full for every event. A typical event day would see stadium staff, players or performers, support staff and media arriving on site 2-4 hours prior to the start of the event. Public entry gates will open approximately 2 hours before kick-off. Most sports events will last approx. 2 hours and the Stadium would be clear of all spectators within an hour of the end of the game.

Functions (i.e. smaller activities not utilising the playing field). Functions could occur on any day of the year and there would be a maximum of about 800 patrons on site. These would held on level L02, L03 or L04. Function patrons would utilise the external car parks with minimal (less than 10) vehicles in the stadium.

Aside from the above listed activities, the site

will be operated from 7AM to 7PM Monday to

Friday with up to 50 staff on site every day.

Staff will enter either via the loading dock on

level L00 or through the glass entry doors in

the middle of the western stand on level L01.

Weekends will see minimal staff on site unless

an event or function is happening.

There will be a security presence on site 24/7

and several of the rooms and facilities on level

L00 will be in use at all times.

2 FLOOD BEHAVIOUR

2.1 FLOOD GENERATING WEATHER

Coastal areas of eastern Australia mostly

receive flooding rains from so-called "east

coast lows" that develop from time to time over

the adjacent Tasman Sea. These are intense

depressions off the coast and can produce

thunderstorm activity associated with troughs.

Depressions can develop at any time of year,

but are most likely when sea surface

temperatures are high and the air is humid.

Therefore, these events usually occur in the

summer months and over the first half of the

year.

Flooding can also be a winter-spring

phenomenon, associated with unusually

frequent or active extra-tropical depressions

and fronts. However some major events have

occurred in the summer half-year as systems

of tropical origin extend or move south.

Flooding over inland areas is usually

associated with southward-moving tropical

systems, but in the cooler months, may occur

when well-developed cloud bands extend

across the interior from the oceans north and

northwest of Australia.

Rainfall patterns are also dependant on longer

term weather patterns. Flooding is more

prevalent in a La Nina year when rainfall is

significantly greater than the mean average

rainfall. Thunderstorms, which generally occur

during the summer, can also result in localised

flooding which could impact specifically on the

site.

2.2 FLOOD PROBABILITIES

Flood probability can be expressed in more

than one way. For example, a flood may be

described as having a 1 in 100 year Average

Recurrence Interval (ARI). This means that

over many thousands of years, a flood of this

magnitude would occur on average once in

100 years. This does not mean that a flood of

this size only occurs once every 100 years. It

is possible to have floods of this size in

consecutive years or even two in the same

year. This happened in several locations in

Queensland and Victoria in 2010 and 2011.

Another way of expressing flood probability is

in terms of Annual Exceedance Probability

(AEP). A 100 year ARI flood has roughly a 1%

AEP. That is, each and every year it has a 1%

chance of being reached or exceeded. This is

perhaps a more helpful way of thinking about

flood probabilities, as it encapsulates the

variability in the frequency with which similar

flood events represent over time. A flood with

a 1% AEP has about a 1 in 2 chance of being

reached or exceeded in the average person’s life time, the same probability of tossing a coin

and getting a head.

Bigger floods can and do occur. There were

several floods with greater than a 1% AEP

experienced in Eastern Australia in early 2011.

Some reached levels which have a 1 in 2,000

(0.005%) AEP. A flood with a 1 in 500 (0.02%)

AEP has about a 1 in 6 chance of being

reached or exceeded in the average person’s life time, the same as tossing a dice and

getting a 6.

The largest flood that can possibly occur is

referred to as the Probably Maximum Flood

(PMF). Although it has a very low probability

of occurring in any one year (1 in 1000,000 or

less), events approaching a PMF have been

recorded.

Flooding may occur at any time of year and at

any time of day. The most recent major floods

in Parramatta – 1986 and 1988 – peaked in

the afternoon and at night however there is no

seasonality associated with flooding in Sydney

and an event could occur at any time of day or

night and on any day of the year.

2.3 FLOODING OF THE SITE

Flooding of the site is primarily caused by the

Parramatta River overtopping its banks,

however minor flooding can also be caused by

rainwater running across the ground (overland

local flooding).

The flood information certificate provided by

City of Parramatta Council (Figure 8 and

Figure 9) shows that the site is flood affected

in the Probable Maximum Flood(PMF). The


site is not affected by floods as large as the

1% AEP event. This means that the site might

flood to some extent only as a result of events

with a probability smaller than 1% per year.

The above information was obtained from the

flood model currently in use at the City of

Parramatta Council, which underpins the

Upper Parramatta River Catchment Flood

Study, undertaken by Bewsher Consulting in

2003. The modelling uses a RAFTS-XP

hydrologic model and a MIKE-11 hydraulic

model. From the early 1990s the model was

progressively updated to account for significant

changes in the catchment including completion

of flood mitigation works. However the

software underpinning the model has now

become obsolete and a new, more accurate

model is being prepared by Council and the

results are likely to be officially released in

early 2020.

2.3.1 Flood Extent and Levels

The flood information certificate provided by

Council for the site does not include the exact

flood levels for the 5% AEP, 1% AEP and PMF

on site, as it usually does for smaller size

developments. Instead, the certificate makes

reference to the attached flood maps (Figure 8

and Figure 9), where flood levels for the above

listed events are extracted at multiple cross

sections of the Parramatta River, upstream

and downstream of the site.

The maps confirm that, according to the flood

model currently used by Council, the site does

not flood in the 1% AEP event, but is affected

in the PMF.

However, the southern car park, which is as

low 6.7m AHD, would be partly flooded in the

5% (1 in 20) AEP flood which reaches 7.02m

AHD at cross section 1935 which is adjacent to

the car park. The highest part of the car park

is at 8.6m AHD and this is about 0.5m higher

than the peak of the 1% AEP flood at this

location (8.14m AHD).

The format of the flood certificate provided by

Council makes it difficult to obtain the exact

peak flood level at the site in a PMF, because

these vary along the river depending on the

location of the cross section. However, a

reasonable estimate of the PMF flood level at

the site can be obtained by interpolating the

levels upstream (profile 1021, PMF level of

13.8m AHD) and downstream of it (profile

1935, PMF level of 13.12m AHD).

Importantly, the flood extents showed in the

map provided by Council would have been

obtained using a topography surveyed when

the old stadium was in place, however the

construction of the new stadium will affect the

local topography as a result of cut and fill

operations.

Figure 6 shows the expected position of the

14m AHD contour line once the new stadium

will be completed. Because the maximum PMF

level will be 13.8m (upstream of the site), it is

reasonable to expect that floodwaters would

not be able to go past the 14m AHD contour

line, meaning that the flood affectation of the

site is likely to be smaller than what is shown

in the flood maps.

Flooding of the site is therefore likely to occur

in two ways. Initially, the river will overtop its

banks in the vicinity of O’Connell Street and rise through the southern car park towards the

site. Given that level L00 is at 9.12m AHD, the

maximum PMF depth at the southern end of

the site would be between about 4m. This

would be sufficient to flood level L00 facilities

and services, the pitch and all of the car

parks.

However, at some point as the river is rising it

would break its banks north and/or west of the

site and flow around the site towards

O’Connell Street where the topography is lower than the river level. For example, at the

peak of a PMF, the river would be overflowing

upstream of the site and would flow east along

the site’s northern access road towards O’Connell Street at a depth of 0.5m or more.

Once it reaches O’Connell Street it would flow south towards the river and join the flood

waters which have reached the L00 level from

the river rising to the south.

2.3.2 Frequency of Flooding

The information provided by Council does not

allow to define exactly from which probability

event the site would start flooding, however

this would be significantly less frequent than

the 1% AEP event. Although it is noted that

the southern car park can begin flooding in

events more frequent than the 5% AEP event.

Importantly, the probability that a large flood

occurs when a major event is taking place at

the site is extremely low, ranging from 0.034%

to 0.0000001%, depending on the event and

the flood AEP (Table 1). For reference, the

probability of an individual being in a fatal car

crash in Australia in year 2016 was

0.005%.(BITRE, 2018), which is about 1,500

times higher than the probability of the site

experiencing a PMF during a 30,000 people

sport event, and 36,500 times higher than this

happening during a 40,000 people concert.

However, it is acknowledged that the number

of people at risk in the stadium during any

individual event is at least 10,000 greater than

the number of people in most car accidents.

2.3.3 Flood Rate of Rise and Duration

Figure 10 shows the hydrograph of the PMF

upstream of the Marsden Street weir extracted

from the Upper Parramatta Mike 11 flood

model. The hydrograph shows the water level

at a point along the Parramatta river between

section 1733 and 1935 in Figure 8. The level at

this point is about 0.2m higher than the gauge

readings at the Marsden Weir.

This hydrograph was used in this study as a

reference as it represents the worst case

scenario of rate of rise in proximity to the site.

Even in events smaller than the PMF,

floodwaters could rise as fast as shown in this

hydrograph. For reference, the peak levels of

the 5% AEP and 1% AEP flood are also

shown, as well as the levels of Level L00 and

Level 01 at the site.

The chart shows that in a flood rising as fast as

the PMF, floodwaters would reach Level L00

after about 2h 20min from the beginning of the

rainfall, and that level would be isolated for up

to 5 hours.

3 FLOOD FORECASTS AND WARNINGS

Monitoring the weather forecasts and warnings

will be an integral step in managing the flood

risk of the site. This will be critical to being

able to evacuate the site before flooding

commences.

3.1 BUREAU OF METEOROLOGY (BOM)

The Bureau of Meteorology (BoM) has a

number of generalised warning products that

could provide an indication of an increased

flood threat:

Severe Weather Warnings.

The Bureau of Meteorology (BoM) issues Severe Weather Warnings whenever severe weather is occurring in an area or is expected to move into an area. The warnings describe the area under threat and the expected hazards. Warnings are issued with varying lead-times, depending on the weather situation, and range from just an hour or two to 24 hours or sometimes more. The key subtype of Severe Weather Warning to be monitored for the site are warnings with reference to flash flooding for the Sydney Metropolitan Area. These are issued directly to the media by the BoM when there is a high probability of flash flooding as a result of intense rainfall. Severe Weather Warnings may also include other conditions such as damaging winds. New South Wales weather warnings are issued by the BoM and can be found at the following link: www.bom.gov.au/nsw/warnings/ and access the relevant warning;

Severe Thunderstorm Warnings.

A severe thunderstorm may produce intense rain and flash floods, hail, damaging winds, and even tornadoes. The BoM provides two types of Severe Thunderstorm Warnings:

- Detailed Severe Thunderstorm

Warnings. These are issued for

capital cities only with up to 60

minutes of notice, and provide more

specific information on individual

severe thunderstorm locations;

- Broad-based State-wide Warnings.

These are based on broad areas

such as the Bureau's weather

forecast districts, and are issued

with up to 3 hours’ notice.

A Flood Watch for the Parramatta River area.

A Flood Watch is a “heads-up” that flood producing rainfall is forecast and flooding may eventuate. These are usually issued one or two days in advance of the expected flooding and about 25% of the time flooding does not eventuate.

In addition to the above listed warning

products, the BoM has forecast rainfall maps

which can be used to estimate the amount of

rain expected to fall over the next eight and

four days, as well as the next 24 hours. This

information is available at the following

website:

http://www.bom.gov.au/jsp/watl/rainfall/pme.jsp

The radar service on the BoM website also

shows current rainfall locations and intensities.

The radar station to be used for the site would

be the Sydney Terrey Hills Radar

(http://www.bom.gov.au/products/IDR714.loop.

shtml#skip).

The Bureau of Meteorology also has rainfall

and river gauges which show the amount of

rainfall that has fallen in the previous 24 hour

period and stream gauges which indicate

water heights. The closest river gauge is

located at the Marsden Weir. Live readings of

the river level can be seen at this webpage:

Plot version:

http://www.bom.gov.au/fwo/IDN60233/IDN602

33.567107.plt.shtml

Tabulated version:

http://www.bom.gov.au/fwo/IDN60233/IDN602

33.567107.tbl.shtml

In order to relate the gauge readings to the

hydrograph shown in Figure 10, an offset of

3.94m should be used to account for the fact

that the gauge zero is 3.74m AHD and that in

floods there is a slope on the water surface

from upstream of the O’Connell Street bridge to the gauge at Marsden Weir of about 0.2m.

For instance, if the gauge reading is 0.5m, the

actual flood level will be:

Flood level AHD = gauge reading + 3.94m

=0.5m+3.94m= 4.44m AHD

3.2 FLOODSMART

In addition to the information provided by the

BoM, the City of Parramatta Council has

recently put in place a local flood warning

system which is freely available to anyone

subscribing to the service. The system is

called “Floodsmart” and can be accessed at the following link:

https://www.cityofparramatta.nsw.gov.au/recre

ation-environment/floodsmart-

parramatta/flood-warning-service

Floodsmart provides flood early warning

messages via text, email, or automated voice

message. The system includes seven different

warning areas covering Parramatta LGA. The

area relevant to the Bankwest stadium is

“Westmead and North Parramatta”. The types of flood warnings provided are

summarised in Table 2.

Table 2. Flood smart warning system: types of warning messages

Type of Warning Message Description

MINOR:

High risk areas may

experience property

flooding

Risk to life from fast flowing or deep water near the river or creek

Closure of roads most at risk of flooding

Flooding of land near rivers, creeks, low spots and recreational areas

Water levels may be high for many hours

MODERATE:

High and Medium risk areas

may experience property

flooding.

High risk to life from fast-flowing or deep water near the river or creek

Closure of many bridges and roads

Widespread flooding in areas not necessarily near the river


MAJOR:

High, Medium and Low risk

areas may experience

property flooding

Damage is possible to buildings and infrastructure

Extreme risk to life from fast-lowing deep water even in areas not near the river or creek

Closure of many bridges, roads and transport routes

Widespread deep flooding in many areas not necessarily near the river


NO FURTHER IMPACT

The local conditions should now be improving:

No further flooding is expected in the next 12 hours

Flood levels will continue to drop

However:

There may still be dangerous fast flowing water near the river or creek

Debris and contamination may still cause problems in areas that have been flooded

https://www.cityofparramatta.nsw.gov.au/recreation-environment/floodsmart-parramatta/flood-warning-service




According to Council’s classification of flood warning areas (Figure 11), the stadium is

classified as a development at LOW RISK of

flooding. As such, it is at risk of flooding only

during a MAJOR flood. However the southern

car park is classified as being at MEDIUM

RISK and it may experience flooding in a

MODERATE flood (Table 3). Floodsmart

warnings can be issued with a maximum

notice of up to 2 hours, however in rapidly

evolving circumstances the warning notice

may be shorter.

3.3 OBSERVED FLOOD LEVELS

While the BoM and Council have several

products which can provide some advanced

warning of potential or actual flooding or

provide real time data on actual rainfall

intensities and river levels, this data may not

be accessible during a flood. This may be

because the severe storms or flooding damage

the gauges or they damage the

telecommunications or electricity infrastructure

needed to transmit data and disseminate

warnings, or there may be human error in

interpreting data and issuing warnings.

It will therefore also be important to visually

monitor water levels in the river. This would

most easily be done from the southern end of

the concourse level looking over the southern

car park.


4 EMERGENCY PREPAREDNESS AND RESPONSE CONSIDERATIONS

The two main types of responses to a flood

emergency are to either:

Evacuate to an area above the reach of floodwaters. This is the NSW SES preferred response, provided that the risks of evacuating are deemed acceptable;

Take Shelter in Place (SIP) (i.e. within the Stadium) and wait until floodwaters have receded and the emergency has passed. SIP is to be considered an alternative to evacuation only when the risks of evacuating are higher than the risks of SIP.

Both evacuation and SIP were considered as

possible flood emergency response strategies

in this FERP. This Section provides a

summary of the flood emergency response

analysis (for evacuation and SIP) that was

undertaken as part of this FERP to inform the

identification of the most suitable response

strategy and management actions.

The analysis was undertaken using a worst

possible scenario approach. Namely, it was

assumed that the worst possible flood (i.e. the

Probable Maximum Flood, or PMF) would

occur during the largest possible event that will

be held at the Stadium (i.e. a 40,000 patron

concert). However it should be emphasized

that flood emergencies are more likely to occur

during normal operating hours (Monday to

Friday, 7AM to 7 PM), when only up to 50 staff

will be onsite, or during the night, when only

security will be on site. Furthermore, most

flood emergencies will be much smaller events

than the PMF.

However, by having a FERP which can cater

for the largest event in the largest flood, all

floods can be appropriately responded to at

any time.

4.1 EVACUATION MODELLING

4.1.1 Scope

An assessment of the evacuation time in the

largest possible site event was undertaken to

understand if:

Evacuation would be possible at all before evacuation routes are cut by floodwaters in a PMF;

At what point in time an evacuation order would need to be issued to provide enough notice for all patrons and staff to leave the site before evacuation routes are cut; and

How often, on average, floodwaters would reach the level selected as a trigger for evacuation. It should be noted that even if the evacuation trigger level is reached and an evacuation order is issued, in most instances floodwaters would stop rising before affecting the site or cutting evacuation routes. However in extremely rare circumstances floodwaters would keep rising to the peak of the PMF and would isolate the site. During a real event it will not be possible to know with sufficient notice when floodwaters will stop rising after the evacuation trigger level is reached. It was therefore deemed desirable that the evacuation trigger level is not reached too often (ideally less often the once every 20 years).

Because in each large event several hundred

patrons would reach the site by car,

evacuation was modelled as a combination of

pedestrian and vehicular evacuation.

4.1.2 Assumptions

The following assumptions were used:

The event would host 40,000 patrons, of which 15,000 would be in the pitch and 25,000 in the seating areas;

Management would take about 10 minutes to decide to evacuate and disseminate an evacuation order after they become aware that the trigger level has been reached;

To avoid traffic delays due to pedestrians blocking access to the road to vehicles and vice versa, pedestrian evacuation

20 VenuesLive

would begin only when vehicular evacuation has completed.

Patrons would decide to evacuate immediately after an evacuation order is issued;

In line with the assumption of the Stadium Emergency Management and Response Plan, it would take up to 8 minutes for anyone in the stadium’s seating area to reach the Concourse level from the moment they decided to evacuate after an evacuation order has been issued. Once on the concourse there would be no further bottlenecks within the stadium to slow down the flow of evacuees (i.e. free flow);

Patrons on the pitch would be able to evacuate by either walking up to the Concourse level (L01) using the aisles in between seats (20 aisles would be available to do so), or walking through the north-east and north-west tunnels at the relevant corners of the pitch. Because the south-east and south-west tunnels terminate at level L00 (i.e. 9.12m AHD), these will be cut earlier that all the other exits and as such it was assumed that these tunnels will be closed during an evacuation. This means that patrons in the pitch would take an extra couple of minutes to reach the Concourse level or to exit the stadium though the north-east tunnel in addition to the 8 minutes mentioned above.

Further assumptions applying to pedestrian

evacuation only:

Pedestrians would exit the site either from the north-east gate at the Concourse level or from the north-east tunnel as these exit points are the closest to a flood free area in the PMF. Pedestrians would then continue walking north along O’Connell St up to the crossroad with Ross St, where some of them would continue on Ross St (Figure 12);

The bottleneck along the pedestrian evacuation route would be in O’Connell St, immediately north of the stadium’s north-east gate. About 40,000 people would need to walk past this point in an evacuation. The road width here is 22m (footpaths plus road), but it was conservatively assumed that only 20m would be available for evacuation;

In line with the relevant literature on pedestrian evacuation (Seyfried et al.,

2005), pedestrians would be able to move at a speed of at least 700 metres per hour, with a density of up to two people per square metre through the concourse and in areas external to the stadium.

Further assumptions regarding vehicular

evacuation only:

People evacuating by car would exit the stadium using the closest exit to the relevant car park and would take about 10 minutes to reach their cars after leaving their seats, as they would need to walk a maximum distance of 500m;

All car parking spots would be occupied in any event. These equate to the following number of cars:

- Northern car park - 292

- Western car park -187

- Southern car park- 348

- Total – 827

In line with the assumptions of the NSW SES Timeline Evacuation Model (Opper et al, 2009), vehicular evacuation would proceed at a speed of 600 cars per lane per hour;

All cars in the southern car park would leave the site from the south driveway and move north along O’Connell St or east along Victoria Rd, then north on Villiers St;

All cars parked in the western and northern car parks (total of 479 cars) would leave the site from the northern driveway and move north on O’Connell Street up to Grose St, then continue in O’Connell St and Grose St;

Each driveway would have two lanes available to exit the car park during a flood emergency.


4.1.3 Evacuation Time Needed

Under the assumptions listed in previous

section, the following evacuation times were

obtained.

a) Pedestrians

It would take 1h 25m for 40,000 pedestrians to walk past the bottleneck in O’Connell Street and reach a flood-free area;

The total pedestrian evacuation time, including 10 min for Management to decide to issue the evacuation order and 8-10 min for patrons to walk to the Concourse level, would be 1h 45 min.

b) Cars

The 349 cars in the southern car park would take 17 minutes to clear. The total evacuation time for this car park, including 10 min for Management to decide to issue the evacuation order, 8

min for patrons to walk to the Concourse level and 10 additional min to walk to the car, would be 45min.

The 479 cars in the northern and western car parks would take 24 minutes to clear. The total evacuation time for this car park, including 10 min for Management to decide to issue the evacuation order, 8 min for patrons to walk to the Concourse level and 10 additional min to walk to the car, would be 52min.

4.1.4 Evacuation Timeline

An evacuation timeline is usually defined by:

Identifying the hydrograph of the worst possible flood event (the PMF) at a known location nearby the site. This is shown in Figure 10 and Figure 13.

Identifying the level of the lowest point along the evacuation route;

Using the hydrographs, identifying the time at which the lowest point is cut by floodwaters;

Figure 12. Pedestrian Evacuation Route

22 VenuesLive

Subtracting the total evacuation time from the time at which the evacuation route is cut to identify the time at which evacuation should begin;

Identifying the level of floodwaters at the time evacuation should begin to set the evacuation trigger.

In this case, given the large size of the site and

the fact that the local topography ranges

between 6.7m AHD and 15m AHD, two

evacuation routes were identified (one

vehicular only for cars in the southern car park,

the other one both pedestrian and vehicular,

for cars in the western and northern car parks

and for all patrons on foot).

The lowest point of each route is at very

different levels and they are each impacted by

flooding rising in the river at different locations.

The lowest point along the evacuation route

from the southern car park is within the car

park itself, at its south-east corner, at a level of

6.7m AHD. This is flooded from water rising in

the river at O’Connell Street at the location

where the hydrograph in Figure 13 has been

extracted from the model. These river levels

are about 0.2m higher than the corresponding

levels at the Marsden Weir about 200m

downstream.

The lowest point along the evacuation route

from the western and northern car parks, as

well as along the pedestrian evacuation route,

is near the junction between the northern

driveway and O’Connell Street, at a level of 13.25m AHD. This is first affected by flooding

from water breaking out of the river north of the

stadium about 1km upstream of O’Connell Street. Water levels at this point are about

0.5m higher than at O’Connell Street in large floods.

The significant difference in ground levels

between these two low points and the river

levels which affect them means that the two

evacuation routes would be cut at very

different times during a flood. Namely, the

southern car park will flood much earlier and

more frequently than the northern driveway.

In these circumstances, having a single

evacuation trigger for the whole site would be

highly impractical, because in most flood

events that trigger an evacuation only the

southern car park would end up flooding (if at

all).

As such, it was decided to evacuate the site in

three stages, each one having its own trigger:

1. A first evacuation order would be

triggered only for patrons who have

parked their cars in the southern car

park, which is the first to flood;

2. If floodwaters continue to rise, a

second evacuation order would be

triggered only for patrons who have

parked their cars in the western and

northern car park;

3. Once vehicular evacuation is

completed, if floodwaters have

continued to rise, pedestrian

evacuation would be triggered.

Alternatively, pedestrians could remain

within the stadium (SIP) until

floodwaters have receded.

A timeline of the above described evacuation

process was generated and associated to the

hydrograph of the PMF near O’Connell Street (Figure 10). This was achieved using the total

evacuation times calculated in Section 4.2.3 to

work backwards from the moment when

evacuation routes are cut and identify the

relevant evacuation trigger levels and times.

The resulting evacuation timeline is shown in

Figure 13.

4.2 CONSULTATION

The evacuation modelling results, assumptions

and timeline described in Section 4.2 were

presented and discussed in a face to face

meeting with:

A representative from the NSW SES;

The Local Emergency Management Officer, who is the liaison officer for all hazards in Parramatta LGA, including floods and fires ;

A representative from Council’s Development Applications Office;

VenuesLive’s General Manager;

Molino Stewart’s flood engineers.

23 VenuesLive

During the meeting the challenges of

evacuation and shelter in place for the site

were identified. A series of measures to

address these challenges were also proposed,

discussed and approved. These are

summarised in the following sub-sections.

4.2.1 Evacuation Challenges

The following challenges of the proposed

evacuation strategy and timeline were

identified:

a) Evacuation of Southern Car Park

Even though the proposed staged evacuation

strategy would avoid unnecessary and

frequent evacuations of all patrons on site,

evacuation of the southern car park would still

be triggered very often. In fact, the trigger level

at the Marsden Weir gauge would be 4.3m

AHD, and the average level at this gauge is

about 4.2m AHD, meaning that a small

fluctuation in level would trigger evacuation of

the car park.

Moreover, issuing an evacuation order only for

patrons who have their cars in the southern car

park would likely cause concern, if not panic,

among all the other patrons.

Finally, patrons who have their cars in the

southern car park would need to walk from a

lower risk zone (i.e. the stadium) to a higher

risk zone (i.e. the car park). Any unforeseen

delays in the evacuation could result in patrons

reaching the car park when this is already

flooding.

To address these challenges, the NSW SES

proposed to close access to the southern car

park before the event, if the available flood

forecasts suggest that a flood large enough to

affect the car park may occur within a few

hours. This suggestion was implemented in

this FERP by creating a series of Alert Modes

and triggers (refer to Section 5.1).

b) Flooding of Level L00 from Southern Gates

In a flood rising as fast as the PMF,

floodwaters would start entering Level L00

about 20-30 minutes after the pedestrian

evacuation order is issued. At that point in time

all patrons at level L00 should have already

evacuated, but any delays may result in

patrons becoming in contact with floodwaters.

Figure 13. Evacuation timeline and trigger levels plotted on the PMF hydrograph near O’Connell Street

24 VenuesLive

In addition to this, Level L00 contains a large

part of the infrastructure and facilities that will

need to be fully operative during a flood

emergency (e.g. power generator and fuel

tank, electric power main switches, fire pump,

security rooms).

These issues will be addressed by water

proofing the two southern access points to

level L00 with two 2.4 m high automatic flood

gates. The western gate will also require a

retaining wall along the road connecting the

southern driveway to the western car park

(Figure 14). The retaining wall will have the

same height as the flood gate (i.e. 2.4m AHD).

The gates and retaining wall will be coupled

with a series of automated backflow blocking

devices to be placed along all drainage pipes

connecting the stadium to the river. This

system will protect level L00 up to a level of

11.52m AHD. Based on the flood levels

provided by Council, it was estimated that this

level corresponds approximately to a 1 in

50,000 year average recurrence interval (ARI)

flood (Figure 15).

c) Risk of Pedestrians Evacuating South

As discussed in Section 4.2, once they have

left the site all evacuees would have to head

north on O’Connell Street, because there is a risk that at that point O’Connell Street will already be cut by floodwaters in proximity to

the river, or that most roads in the CBD will be

cut by local flooding. However patrons who will

reach the site on foot will likely arrive at

Parramatta by train or bus, and both the train

station and the bus interchange are located

south of the river. Other patrons may decide to

drive and park their cars in one of the covered

secure car parks in the CBD. These patrons,

when asked to evacuate, would naturally go

home in the same way they arrived to

Parramatta, and would therefore try and walk

south on O’Connell Street and cross the river.

This risk will be addressed by ensuring that

when pedestrian evacuation commences,

there is a sufficient number of staff in

O’Connell Street advising evacuees to walk north.

d) Where to Evacuate?

Even if all pedestrians evacuated north using

the designated evacuation route, there would

be no suitable facilities within walking distance

to receive such a large number of people.

Evacuees would most likely have to wait in the

streets until floodwaters withdraw, under

intense rain and without any of the services

that the stadium would have otherwise

provided (e.g. shelter, sustenance, access to

toilets, access to information, access to

medical aid). This may expose evacuees to

risks that could be deemed higher than the

risks associated with taking shelter within the

stadium.

This issue was discussed during the

consultation meeting and it was agreed that

the most appropriate solution would be to offer

patrons the choice to either evacuate or shelter

in place. This will be done by providing suitable

information to patrons regarding the

implications of evacuating or taking shelter in

place. This information will be provided via

emergency messages issued via the PA

system.

4.2.2 SIP Challenges

If patrons made the decision to take shelter

within the stadium until the emergency has

passed, in the worst possible scenario they

would be isolated by floodwaters for about 2h

40min (Figure 13). In addition to the relatively

short isolation time, the maximum water depth

along the evacuation route would be around

0.5m. While it is widely acknowledged that

there are risks associated with taking shelter in

place, these are generally greater for longer

isolation times. Nevertheless, the risks of SIP

were identified and addressed as part of this

FERP. These include:


Figure 14. Position of flood gates and retaining wall to water proof the southern access points to level L00

26 VenuesLive

a) Patrons Walking through Floodwaters

Some patrons might become impatient while

the site is isolated and walk though

floodwaters. This is a known risk for any SIP-

based response strategy and can exacerbated

by circumstances in which there is a lack of

power, sustenance, access to medical care, or

overall comfort or inability to access

information of the expected duration of

isolation.

These risks will be reduced by:

Reducing the probability of power failure to acceptable levels. The stadium will be equipped with two independent power substations. If both substations ceased to function, an emergency power generator located al level L00 would automatically turn on. Furthermore, Level L00 will be protected from flooding with flood gates and retaining walls as described in previous section up to flood events as rare as the 1 in 50,000 ARI (corresponding to a 0.002% AEP on any day or about a 0.00004% AEP during an event).

Providing access to food and water. The stadium will host several food and beverage retailers. It is expected that the normal stock of food and beverage will be sufficient to cover any sustenance needs for an isolation time of less than 3h. Furthermore, the stadium management will have authority to distribute food and beverage free of charge, should this become necessary. A decision to do so will be made based on an assessment of isolation time and overall condition of patrons.

Providing shelter from the rain and access to toilets. The stadium roof was designed to provide satisfactory protection against weather and rain to patrons in the seating area. During concerts however, patrons in the pitch would be exposed to the rain and may try to climb up in the seating area to seek shelter. This may result in a higher density of patrons in the seating area, which could eventually lead to public order issues. This risk will be reduced by (a) providing patrons a chance to evacuate, which will create additional room in the covered seating area, and (b)

Providing updates on the expected flood duration based on communications with the NSW SES. Updates will be provided using the video screens and PA system and the Emergency Warning Intercom System (EWIS), a fire safety system controlled from the Fire Panel with speakers all around the venue.

b) Patrons Requiring Medical Attention

A medical team will be on site with sufficient

staff and equipment to deal with the risk profile

of each event, as defined in the stadium

Emergency Management and Response Plan.

The medical services provider will have a

number of staff on site and be supported by St

Johns Ambulance for every event.

c) Risk of Fires

A secondary risk generally associated with SIP

is the risk of fire. This risk is exacerbated when

the isolation time is long and there is lack of

power in residential dwellings where people

may improvise cooking, heat and lighting using

naked flames. food, light or heat, pushing

people to light With an isolation time of less

than 3 hours, a non-residential setting and

emergency power supplies it is extremely

unlikely that the risk of fire at the venue would

be increased during a flood. Nonetheless, the

risk of fire will be managed according to the

stadium Fire Emergency Plan, and will be

reduced thanks to the stadium automated fire

suppression system.

In addition to the above, the stadium will

feature the following emergency management

equipment:

Public Announcement (PA) system. The PA system features sufficient speakers to reach each part of the playing field and seating area. The PA system control room will be located well above the reach of floodwaters at level L04.

The Emergency Warning Intercom System (EWIS), a fire safety system controlled from the Fire Panel with speakers covering every part of the venue. This will be used for official emergency communications such as evacuation messages. EWIS will have a larger reach than the PA system, which was designed for entertainment purposes and will cover only the pitch and seating areas.

Video screen. A large screen will be installed on top of the seating area and will be visible from the pitch and all seats. The screen main purpose will be to provide information related to the event being held, but if needed will be used for emergency purposes. For instance, flood emergency messages will be displayed on the screen.

A CCTV camera system. The system will cover all parts of the site including the car parks. Live videos will be transmitted to the control room at level L04 and will be monitored by the Chief Warden (or delegates).

5 FLOOD EMERGENCY RESPONSE PLAN

This section outlines the basic principles

underlying flood emergency response (Section

5.1), roles and responsibilities (Section 5.2),

communication methods (Section 5.3) and the

list of response actions and triggers (Section

5.4).

5.1 EMERGENCY RESPONSE PHILOSOPHY

5.1.1 Priorities

This FERP recognises that protection of life is

of critical and primary importance. This FERP

is principally concerned with the safety and

comfort of patrons and staff. All flood

emergency responses recommended in this

FERP are to recognise the primacy of life and

wellbeing over property.

Nonetheless, it is recommended that the

Stadium Management and staff take all

necessary measures outside of this FERP to

manage the risks which flooding poses to the

site.

The FERP sets emergency management

prevention, preparedness and response

measures that are relevant to a flood

emergency. Broader emergency management

guidance for any type of hazards that could

affect the Stadium are defined in the Stadium

the Emergency Management and Response

Plan under which this FERP sits.

5.1.2 Alert Modes

To assist in managing flood risks and

communicating response actions, five flood

alert modes have been developed for use in

this FERP. They have been colour coded to

further assist in communication. They are:

White: normal operations

Yellow: flooding of the site in the next 24 hours may be possible

Orange: flooding of the southern car park in the next two hours is possible

Red: flooding of the site in the next two hours is possible

Black: flooding of the site is possible within the next hour

Green: all clear, floodwaters have withdrawn and there is flood-fee access to or from the premises

These may be revised up or down depending

on the changing forecasts and actual

conditions. Once a decision is made to cancel

an event this cannot be revised.

An Alert Mode Table has been developed

which nominates thresholds that trigger

escalation of alert modes.

It is recommended that the Alert Table plays a

key role in the planning and training processes

before a flood occurs, as well as when flooding

is possible and when it does happen. It will be

important to maintain the Alert Table and

update this if new information is made

available and review it after events which

trigger any level of flood response.

The Alert Mode Table is shown in Table 4 and

will be used to define the trigger points for

undertaking actions when flooding is occurring

or could possibly occur.

It should be stressed that the Alert Mode

MUST be escalated if any one of these

thresholds alone is reached or exceeded

because there is a high degree of certainty that

the corresponding management actions will be

necessary.

5.2 RESPONSIBILITIES

Roles and responsibilities in case of an

emergency are defined in detail in the Stadium

Emergency Management and Response Plan.

This section will provide an overview of the key

information that is relevant to a flood

emergency.

The responsibility of successful

implementation of the Flood Emergency

Response Plan lies with the site management

(VenuesLive), however the NSW SES, as the

State combat agency for flood events, and the

NSW Police Force have right to and may

intervene before, after or during a flood to

provide guidance or prescriptive directions to

VenuesLive. Any decision to evacuate the site

will be made in consultation with the NSW SES

and the NSW Police Force.

VenuesLive will provide the following staff

resources to coordinate the management of

flood emergencies:

The Emergency Organisation Committee (ECO), including members of the Stadium Management who are trained in emergency preparedness and response. The ECO will represent VenuesLIve senior management and will have authority to escalate alert modes and issue emergency messages to staff and patrons;

A Chief Warden, who will be located in the Event Control Room and have access to the resources necessary to manage an incident (e.g. flood alert triggers, CCTV cameras, flood gate controls, PA system). The Chief Warden will be a senior member of the Stadium Management Team. The Chief Warden will be onsite during events. During normal operating hours, a Chief Warden will be nominated by the ECO should a flood emergency arise;

Area Wardens and Wardens. These will be members of VenuesLive’s Customer Service and Security teams, and will be trained to deal with all types of emergencies. Area Wardens and Wardens will follow the directions of the Chief Warden. An Area Warden will be responsible for a number of Wardens in a particular area (e.g. level 3 Area Warden may have 6 Wardens on level 3

positioned at critical doors or on egress paths). For a capacity 30,000 football event there will be approximately 30 Area Wardens and 200 Wardens on site.

Ask the NSW SES to provide regular updates on the flood emergency and to provide an “all clear” notice as soon as the emergency has passed;

The ECO will:

Within 10 minutes from receiving communication that the stadium has entered the Black Alert Mode, make a decision about issuing a voluntary pedestrian evacuation warning message. Consultations with the NSW Police Force and/or the NSW SES are recommended if time allows. In making this decision, the ECO should consider whether:

- A. vehicular evacuation from all car parks has successfully completed. If this is the case, there will be enough time to complete a pedestrian evacuation before evacuation routes are cut. If this is not the case, evacuation routes may cut before pedestrian evacuation has successfully completed, and asking patrons to take shelter within the stadium would be a safer alternative; and

40 VenuesLive

- B. an event cancellation notification has already been issued to all patrons in the stadium. In this case patrons may be already leaving the site and a further evacuation message will not be necessary.

Trigger for action:

Vehicular evacuation from all car parks has successfully completed when the Black Alert Mode is activated

AND

An event cancellation notification has NOT

been issued to all patrons in the stadium

AND

the ECO issues a voluntary pedestrian evacuation warning message

Within 10 minutes from receiving communication that the stadium has entered the Black Alert Mode, make a decision about issuing a voluntary pedestrian evacuation warning message. Consultations with the NSW Police Force and/or the NSW SES are recommended if time allows. In making this decision, the ECO should consider whether:

- A. vehicular evacuation from all car parks has successfully completed. If this is the case, there will be enough time to complete a pedestrian evacuation before evacuation routes are cut. If this is not the case, evacuation routes may cut before pedestrian evacuation has successfully completed, and asking patrons to take shelter within the stadium would be a safer alternative; and

- B. an event cancellation notification has already been issued to all patrons in the stadium. In this case patrons may be already leaving the site and a further evacuation message will not be necessary.
