GLOSSARY

Annual Exceedance Probability (AEP). The chance of a flood of a given or larger size occurring in any one year, usually expressed as a percentage. For example, if a peak flood level (height) has an AEP of 5%, there is a 5% chance (that is, a one-in-20 chance) of such a level or higher occurring in any one year (see also Average Recurrence Interval).

Assistance Animal. A guide dog, a hearing assistance dog or any other animal trained to assist a person to alleviate the effect of a disability (Refer to Section 9 of the Disability Discrimination Act 1992).

Australian Height Datum (AHD). A common national surface level datum approximately corresponding to mean sea level.

Average Recurrence Interval (ARI). The long-term average number of years between the occurrence of a flood as big as, or larger than, the selected event. For example, floods reaching a height as great as, or greater than, the 20 year ARI flood event will occur on average once every 20 years.

Catchment (river basin). The land area draining through the main stream, as well as tributary streams, to a particular site. It always relates to an area above a specific location.

Design flood (or flood standard). A flood of specified magnitude that is adopted for planning purposes. Selections should be based on an understanding of flood behaviour and the associated flood risk, and take account of social, economic and environmental considerations. There may be several design floods for an individual area.

Essential services. Those services, often provided by local government authorities, that are considered essential to the life of organised communities. Such services include power, lighting, water, gas, sewerage and sanitation clearance.

Flash flooding. Flooding which is sudden and often unexpected because it is caused by sudden local or nearby heavy rainfall. It is sometimes defined as flooding which occurs within six hours of the rain that causes it.

Flood. Relatively high water level which overtops the natural or artificial banks in any part of a stream, river, estuary, lake or dam, and/or local overland flooding associated with drainage before entering a watercourse, and/or coastal inundation resulting from super-elevated sea levels and/or waves overtopping coastline defences.

Flood classifications. Locally defined flood levels used in flood warnings to give an indication of the severity of flooding (minor, moderate or major) expected. These levels are used by the State Emergency Service and the Australian Government Bureau of Meteorology in flood bulletins and flood warnings.

Flood intelligence. The product of collecting, collating, analysing and interpreting flood-related data to produce meaningful information (intelligence) to allow for the timely preparation, planning and warning for and response to a flood.

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan ix

Flood liable land. Land susceptible to flooding by the Probable Maximum Flood. (PMF) event. This term also describes the maximum extent of a floodplain which is an area of a river valley, adjacent to the river channel, which is subject to inundation in floods up to this event.

Flood of record. Maximum observed historical flood.

Flood Plan. A plan that deals specifically with flooding and is a sub-plan of a Disaster Plan. Flood plans describe agreed roles, responsibilities, functions, actions and management arrangements for the conduct of flood operations and for preparing for them.

Floodplain Management Plan. A plan developed in accordance with the principles and guidelines in the New South Wales Floodplain Development Manual. Such a plan usually includes both written and diagrammatic information describing how particular areas of flood prone land can be used and managed to achieve defined objectives.

Floodway. An area where a significant volume of water flows during floods. Such areas are often aligned with obvious naturally-defined channels and are areas that, if partially blocked, would cause a significant redistribution of flood flow which may in turn adversely affect other areas. They are often, but not necessarily, the areas of deeper flow or the areas where higher velocities occur.

Flood Watch. A Flood Watch is a notification of the potential for a flood to occur as a result of a developing weather situation and consists of short generalised statements about the developing weather including forecast rainfall totals, description of catchment conditions and indicates streams at risk. The BoM will also attempt to estimate the magnitude of likely flooding in terms of the adopted flood classifications. Flood Watches are normally issued 24 to 36 hours in advance of likely flooding. Flood watches are issued on a catchment wide basis.

Flood Warning. A Flood Warning is a gauge specific forecast of actual or imminent flooding. Flood Warnings specify the river valley, the locations expected to be flooded, the likely severity of flooding and when it will occur.

Geographic Information System (GIS). A computerised database for the capture, storage, analysis and display of locationally defined information. commonly, a GIS portrays a portion of the earth‟s surface in the form of a map on which this information is overlaid.

Local overland flooding. Inundation by local runoff rather than overbank discharge from a stream, river, estuary, lake or dam.

Major flooding. Flooding which causes inundation of extensive rural areas, with properties, villages and towns isolated and/or appreciable urban areas flooded.

Minor flooding. Flooding which inconvenience such as closing of minor roads and the submergence of low-level bridges. The lower limit of this class of flooding, on the reference gauge, is the initial flood level at which landholders and/or townspeople begin to be affected in a significant manner that necessitates the issuing of a public flood warning by the Australian Government Bureau of Meteorology.

Moderate flooding. Flooding which inundates low-lying areas, requiring removal of stock and/or evacuation of some houses. Main traffic routes may be covered.

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan x

Peak height. The highest level reached, at a nominated gauging station, during a particular flood event.

Probable Maximum Flood (PMF). The largest flood that could conceivably be expected to occur at a particular location, usually estimated from probable maximum precipitation. The PMF defines the maximum extent of flood prone land, that is, the floodplain. It is difficult to define a meaningful Annual Exceedance Probability for the PMF, but it is commonly assumed to be of the order of 104 to 107 (once in 10,000 to 10,000,000 years).

Runoff. The amount of rainfall which ends up as streamflow, also known as „rainfall excess‟ since it is the amount remaining after accounting for other processes such as evaporation and infiltration.

Stage height. A level reached, at a nominated gauging station, during the development of a particular flood event.

Stream gauging station. A place on a river or stream at which the stage height is routinely measured, either daily or continuously, and where the discharge is measured from time to time so as to develop a relationship between stage and discharge or rating curve.

ANNEX A - THE FLOOD THREAT

LANDFORMS AND RIVER SYSTEM(S) 1. Flooding is common on the many short, steep streams that flow eastward from the Illawarra Escarpment across the urbanized coastal plain. The escarpment begins as a coastal cliff rising to 250 m elevation in Wollongong's northern suburbs and rises to a height of 670 m to the west of Dapto at which point it is about 20 km from the sea. East of the escarpment is a series of low ridges divides the small, steep stream catchments. The coast proper is lined with sand dunes, which impound small lagoons and swampy areas into which these creeks discharge. To the south of the city is the 35 square kilometre Lake Illawarra, a shallow tidal lake that occupies the area between plain and coastal dunes. The council area has been divided into eight areas of study used by Flood Management Committee (see Maps Section). The areas are also used in relation to flood risk identification for the purpose of emergency response. These areas are:  Area 1 – North from Flanigans Creek, Thirroul to Clifton  Area 2 – Includes Hewitts, Woodlands and Slacky Creek systems.  Area 3 – Extends from Bulli to Corrimal and includes Whartons, Collins, Farrahars and Bellambi Gully Creeks systems.  Area 4 – Encompasses the Towradgi Creek system in the Corrimal area.  Area 5 – Centres on the central Wollongong area and includes Cabbage Tree Creek and Fairy Creek catchments.  Area 6 – Covers the Mount Keira to Farmborough Heights areas  Area 7 – Covers the Mullet Creek catchment from Farmborough Heights to Avondale.  Area 8 – Is devoted to a small region in the Lake Heights area.

There are also several minor creeks that flow westward from the escarpment through unpopulated country to a series of water storage reservoirs. The more important of these, and the storage's to which they feed, are:

 Avon River and Gallahers Creek: to Lake Avon.  Cordeaux River and Kembla Creek: to Lake Cordeaux.  Rocky, Cataract, Bellambi and Allen Creeks: to Lake Cataract.  Waratah Rivulet: to Lake Woronora.

O'Hares Creek, a tributary of the Georges River, also flows west from the escarpment.

WEATHER SYSTEMS AND FLOODING 2. Flooding can occur at any time of the year, but in different seasons it is triggered by different rain-producing mechanisms. There is a slight bias towards the February-March period as well as August as far as flood occurrence is concerned. Within this period the concentration is in the late summer and early autumn months. 9 8

Table 4 - Flood Occurrences for Wollongong LGA by Month: 1950-1999 (Source: Wollongong City Council)

Floods may result from any of the five weather patterns summarized below: a) Ex Tropical Cyclones: Rainfall and flooding that results from a cyclone moving south and downgraded to a rain depression. Such weather systems can produce prolonged heavily rainfall. Heavy rainfall originating from these cyclones in the Illawarra can occur anytime between January and May and have historically resulted in widespread and localised flooding affecting dwellings. b) Zonal Synoptic Patterns: This pattern occurs when the centre of a high or low-pressure system is located south of New South Wales directing a moist onshore flow onto the coast. These pressure systems often combine with a low-pressure trough and/or upper air disturbances to create a state of prolonged instability. In February 1984, moist air behind a front and a high-pressure system centred southeast of Tasmania, along with small surface low-pressure systems, resulting in extreme instability and intense rainfall. Zonal synoptic patterns together with easterly lows account for 50% of the flooding in the Illawarra. c) Inland Depressions: These inland depressions or low-pressure systems originating from continental northern Australia that can dip down into New South Wales and intensify over coastal areas. These often occur in autumn, just after the northern monsoon season. d) Easterly Lows: Defined as low-pressure troughs moving south from Queensland, generally just off the NSW coastline, before heading in a south-easterly direction. They occur predominately in the winter months.

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan A-3

e) Continental Lows: Low-pressure systems, which move across the continent towards the central NSW coastline. There is two types;  Lows originating from central and southern Queensland moving south towards Sydney, intensifying as they near or cross the coastline. Unlike inland depressions no trough structure is evident.  Where a low-pressure system moves eastwards across the southern continental areas, before intensifying near the coastline, thereby producing intense rainfall. East coast cyclones or lows as identified by Bryant(1991) would also fit into this category (these are easterly moving pressure systems, which develop into intense cyclonic depressions when they pass over mountainous coastal terrain and a warm poleward flowing current. Predominately occur in winter and autumn. f) Thunderstorms: Localised thunderstorms have caused localised flooding in various areas, usually to only sections of a suburb at any one occasion. FLOOD HISTORY 3. Average annual rainfall in the council area varies from less than 1,100 mm in the Dapto, Windang and Kemblawarra area to more than 1,600 mm along the escarpment southwards from Mt Keira. About 60-70 per cent of this falls in the summer and autumn quarters most of it in February, March and April. Rainfall of more than 50mm in a day is recorded, on average, about eight times a year somewhere in the council area. Such rainfall frequently produces flooding, particularly when catchments are already wet. Very high daily falls (200 mm or more) almost always produce flooding, much of it severe.

Table 5 – No of Floods by Severity:1950-1999 (Source : Wollongong City Council) In recent decades, flooding has tended to occur frequently in some periods and then to become less common. Floods were common in the 1950-52, 1958-61, 1973-78, 1983-84, 1991-92 and 1998-99 with periods but much less so in the intervening periods. Severe floods are more common in the February-March period and in August than in other months.

CHARACTERISTICS OF FLOODING IN THE WOLLONGONG COAST CATCHMENT AREAS 4. The dominant feature of flooding in the council area is that it is usually 'flash' flooding. The streams respond quickly to high-intensity rainfall and flooding can begin very soon after the beginning of heavy rains. Due to the nature of the topography rainfall can be concentrated within one catchment area without effecting other or neighbouring catchments. Except for their headwaters, most of the catchments are heavily urbanised; a feature which increases the speed of rises in creek levels. Floodplain areas are of relatively limited size, and during periods of flooding only small proportions of total flow are carried within creek channels. The result is substantial floodplain inundation, often to considerable depths. Velocities of flow are usually high (often more than 2 metres per second) and flooding is characterised by very rapid rises and falls in water level. As it is common in urban catchments, flood peaks usually occur at night time. Overbank flows occur frequently, even in the less severe events of approximately 20-50% AEP (that is, floods that occur on average every 2 to 5 years). Most of the creeks have been significantly modified by human intervention, and the construction of buildings near the watercourse can sometimes divert flows over areas some distance from the creeks themselves. Filling of land in the lower reaches of catchment causes water that would otherwise have remained within the banks of the streams to break out and in severe events upstream flood levels can be significantly higher than would previously have been the case. The north-south orientation of the road and rail links means that all the creeks are interrupted by culverts and bridges which have limited flow capacity that are prone to blockage by debris, worsening these effects. Few road culverts are capable of passing events more severe than those of about 10 % AEP without overtopping. Inadequate waterway capacity or blockages are a frequent cause of flooding. Most of the creeks discharge into small coastal lakes, lagoons or swamps before reaching the sea. The mouths are prone to closure through build-up of sand at their outlets. This causes flood levels in the lakes and in the lower stream reaches to rise in the early stage of a flood before the flood waters scour the outlet. High velocities are often experienced at the outlets as the sand bars collapse. Previously observed flooding behaviour in watercourses in the area have generally been characterised by:  Peak flood discharges significantly greater than the capacity of the watercourses.  Rapid rise and fall of flood levels.  High flood velocities resulting in extensive damage to creek bank vegetation and erosion of creek beds and crossings.  Large quantities of flood debris. At a number of locations the quantity of flood debris appeared to exacerbate upstream flooding by blocking culvert and bridge waterways.

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan A-5

The design capacity of the urban stormwater drainage system in the area of interest is understood to be based on a 10 year or smaller Average Recurrence Interval (ARI) storm event. Hence, some properties have been flooded by surcharging of the stormwater drainage system and/or the inability of local runoff to enter the stormwater drainage system independent of, or in combination with mainstream flooding. Because of the short catchment response times, it is extremely difficult to accurately determine the timing and contribution of local flooding to overall flooding at a given built-up location in the study area. Thus, the determination of the likelihood and contribution of stormwater flooding requires some subjective assessment. Northern Suburbs Catchment Response times from rainfall to effect on ground can be as low as 15 minutes. The short distance from the steep catchment of the escarpment to the outflow at the ocean means the flood flows are of high velocity. This increases risk of scouring of creek banks, overflow onto roads and public access areas and undermining of properties. All creek systems run through culverts or under bridges that are prone to debris blockage. Resultant blockage causes overflow of flood waters onto roads and through properties. This increases the risk to life for exposed people. Hewitts Creek Catchment Catchment area is 7.5km2 with average annual rainfall being around 1500mm on the escarpment and 1300mm at the coast. Most flows are contained within the creek banks in upper reaches of the catchment but the rapid rise and high velocities increases the risk of scouring of the creek banks and undermining of properties. Filling of land in the lower reaches of some of the catchment has significantly reduced the pre-existing storage capacity of the floodplain. Many culverts and bridges have been constructed within the creek system in the lower reaches which are vulnerable to blockage from debris. Ocean conditions contribute to back up of flood waters unable to expel into the ocean. Also sand build up at the ocean outlets can restrict flow. There are a number of known “hot spots” located upstream of the railway line and along north-south orientated roadways and embankments. Collins Creek Catchment The upper reaches of the catchment are fed by runoff which originates in the escarpment. The outlets for the creeks in this catchment flow into a coastal estuary environment which is subject to entrance filling as a result of wave action. This may result in reduced ability for outflows and also effects outflows during storm surge periods. Flows quickly spill out of the creek banks east of Princes Hwy in a 20% AEP. Flooding within the catchment has been reasonably frequent. The Catchment has experienced significant flood events in October 1987, April 1988 and August 1998. Towradgi Creek Catchment The Towradgi Creek catchment drains an area of about 7.2km2 through the northern Wollongong suburbs of Tarrawanna, Corrimal, Towradgi and Fernhill. About 50% of the catchment is steep and forested and forms part of the Illawarra Escarpment. The

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan A-6 lower half of the catchment is much flatter and mostly urbanised. Towradgi Creek flows into the Pacific Ocean at Corrimal Beach. The Towradgi Creek catchment has suffered regular flooding with 24 instances of flooding occurring in the district from 1958 to 1989. On 17 August 1998 the largest flood on record was experienced within the catchment. At least 40 houses and units were flooded above floor level and the retail area in Corrimal was severely damaged. Vehicles were swept off flooded roadways and some residents battled very hazardous conditions whilst evacuating their flooded properties. Analysis of this flood showed that the peak flood flow of the August 1998 flood was smaller than the 100 year flood in the upper and middle parts of the catchment and just larger than the 100 year flood in the lower part of the catchment. Fairy and Cabbage Tree Creek Catchments Fairy Creek is located immediately north of Wollongong. The four main branches of the creek rise high upon the slopes of the Illawarra escarpment east of Mount Keira. The Fairy Creek catchment occupies an area of approximately 7.6 square kilometres to the confluence with Cabbage Tree Creek. The catchment area is subject to rainfalls of high intensity and is characterised by steep slopes and a high degree of urbanisation. The confluence of Fairy and Cabbage Tree Creeks (catchment area 10.5 square kilometres) occurs at a tidal lagoon just upstream of the Squires Way Bridge. There have been 37 floods since 1945. The area worst affected by flooding is at North Wollongong between the Illawarra Railway and the Cabbage Tree Creek confluence. Significant floods causing damage and/or transport interruptions occurred in 1949, 1950, 1955, 1956, 1958, 1959, 1961, 1964, 1974, March 1975, 1977, 1978 and March 1983. Allans Creek Catchment Flooding within the catchment has posed a high hazard to the residents living in close proximity to major watercourses. Major transport links and local roads have been inundated by flood waters making evacuation and emergency access difficult. There have been recorded flood rescues occurring in this catchment. Flooding within the catchment has been reasonably frequent. Allans Creek has experienced significant flood events in March 1975, March 1978, March 1983, October 1983, February 1984, June 1991, August 1998 and October 1999. The rate of flood waters for a 1% AEP has been calculated to approximate 7.8m/hr. Time to flood peak can be less than 1 hour in some areas with some overbank flooding in the upper reaches of the catchment occurring within 15min of heavy rainfall. The lower reaches will have greater warning time with possibly 60-90 minutes. Mullet Creek Catchment The study area comprises two catchments, Mullet Creek and Brooks Creek, which drain areas of about 72 km2 and 5 km2, respectively. Both watercourses discharge separately to Lake Illawarra. Has a small and steep catchment which regularly experiences very heavy rainfall. Due to the proximity of the escarpment and rapid descent from headwaters to floodplain floods tend to be in the flash flood category with rapid rises and falls. Response times from rainfall to effect on ground are typically in the order of less than 6 hours. The last major flood in this catchment occurred in 1984 where numerous flood rescues occurred. Access to West Dapto is regularly lost in lesser events that can

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan A-7 isolate the area for the period of rainfall plus a number of hours after cessation of rainfall. The levels in Lake Illawarra can contribute to the effects of flood around the lake foreshore and into the floodplain.

Minnegang Creek Catchment The Minnegang Creek catchment is located 8.5km south of Wollongong. The steep catchment rises from the northern shore of Lake Illawarra to the intersection of Lake Heights Road and Flagstaff Road. Approximately 80% of the catchment is developed, mostly with low density residential housing, with the remaining 20% being recreational area or cleared open space. There have been several large flood events in the catchment within the last twenty years, the most significant being: 14 December 1985, 23 October 1987, December 1990, 17 August 1998 and 24 October 1999. There is limited information regarding the nature of these flood events aside from the August 1998 storm event, which had a recurrence interval of approximately two years in the vicinity of Minnegang Creek catchment. Over much of the catchment there is little difference between the flood extents for events of different AEP, including the PMF extent. The peak flows and flood levels along Minnegang Creek occur after approximately 40 minutes in the upper parts of the catchment. In smaller events, such as the 20% AEP event, the peak flows downstream of the Barina Park detention basin occur approximately one hour following the start of the storm event. Along the tributaries and minor branches of the creek, the time to peak flow is approximately 20-30 minutes. Due to the contained nature of the flood flows within the catchment, only a relatively small number of properties within the catchment are affected by flooding. Lake Illawarra Lake Illawarra is a shallow coastal lagoon located on the undulating coastal plain between the ocean and the cliffs of the Illawarra Escarpment. The Lake Illawarra Catchment has an area of 760 km2, rising from sea level to an elevation of 760m at Mount Murray. Several surrounding water courses feed in to the Lake. These being Macquarie Rivulet, Mullet Creek, Brooks Creek, Hooka Creek, Duck Creek and, Horsley Creek.. The catchment is largely rural, with some residential and commercial land uses located mainly in the lower catchment. In times of flood, the water levels of Lake Illawarra are heavily reliant on whether the headlands of the catchment system are open or not. The catchment has suffered regular flooding with 13 instances of historical events recorded ranging from 1919 till August 1998. Key flooding events occurred in 1975, 1977, 1984 and 1998.

COASTAL FLOODING 5. Along the coast proper, sea conditions can have a pronounced effect on flood character. High tides, wave set-up and storm surge can all be influential. Storm surge is an increase in the sea water level at the coast. The principal factors in the generation of a storm surge are: a. The wind stress on the sea surface, piling up water.

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan A-8

b. The atmospheric pressure reduction in the storm area raising sea water level. c. The net water transport shoreward due to waves and swell breaking in the shallows. d. The local surge modification due to bottom topography, abnormally heavy rainfall and the presence of currents, tides and natural oscillations. In addition to wind and barometric set-up there is an additional rise in water level on the beach due to wave set-up. The wave set-up occurs between the zone of breaking waves and the beach, and can be as much as 10 to 20 per cent of the incident wave height. The maximum water levels from a combination of high tides, wave set-up and storm surge could be greater than 2.0 metres AHD. Of this, high tide levels and wave set-up would account for much more than storm surge, which is estimated to be able to contribute only about 0.4 metres.

Causes of flooding in coastal lakes and estuaries Flooding within coastal catchments may be caused by: a. An elevated lake level due to intense rainfall over the catchment. The lake level rises when runoff inflow into the basin is greater than outflow into the sea from the lake. b. Elevated water levels within individual creeks as a result of intense rainfall over local catchments. c. Local runoff over a small area accumulating in low spots. d. Elevated ocean levels. Frequently elevated ocean levels are caused by storm surge. e. Local wind conditions generating waves and setup across the fetch of the lake. These factors may occur in isolation or in combination with each other. In particular, the combination of elevated ocean levels, strong winds and peak inflows into the basin are considered to be particularly hazardous.

IMPACTS OF CLIMATE CHANGE 6. Climate change modelling suggests that there are likely to be reductions in average annual rainfall, but an increase in the intensity of rainfall events when they do occur. Hence, creating a future rainfall regime characterised by longer dry spells interrupted by heavier rainfall events. The frequency of coastal flooding may increase as a consequence of sea level rise and the potential increased frequency of storm surge events

The lake has an average depth of approximately 1.7m with the maximum depth being around 4m. The floodplain lies within both the Wollongong City Council and the Shellharbour City Council local government areas. The Lake is generally open to the sea through an entrance channel that is affected by ocean storms, wave action, floods and tides. The main contributing tributaries are Mullet Creek, in the Wollongong LGA, and the Macquarie Rivulet, in the Shellharbour LGA. A number of properties adjacent to the Lake are susceptible to above-floor flooding in the 1% Annual Exceedance Probability (AEP) and the Extreme Flood/Probable Maximum Flood (PMF) events.

Floodwaters accelerate into the entrance channel out to the Tasman Sea. The rate and depth of flooding of the lake and its foreshores are controlled not only by the rate of catchment runoff but also to a large extent by the size and degree of shoaling of the lake entrance channel and the ocean level.

ANNEX F - EVACUATIONS ARRANGEMENTS Arrangements 1. Control. During floods evacuations will be controlled by the NSW SES. Small-scale evacuations will be controlled by the Wollongong City SES Operations Controller. Should the evacuations operations escalate beyond the capabilities of local resources control may be handed over to the Illawarra South Coast SES Region Operations Controller. 2. Conduct. Evacuations will be controlled by the SES Operations Controller and conducted with assistance from the NSW Rural Fire Service, NSW Police, NSW Fire Brigade, Ambulance of NSW and service club personnel. 3. Evacuations will be controlled by the SES and conducted in four phases: Phase 1 - Warning. Phase 2 – Withdrawal. Phase 3 – Shelter. Phase 4 – Return. Decision to Evacuate 4. The responsibility for issuing any general evacuation order during flooding rests with the Local SES Operations Controller who exercises his/her authority in accordance with section 22 (1) of The State Emergency Service Act 1989. During the possibility of large-scale evacuations the decision to evacuate will usually be made after consultation with the Wollongong City LEOCON and the Illawarra South Coast Region Operations Controller. 5. When evacuations should occur. As far as possible, evacuations will be carried out before inundation occurs. Due to the flash flood nature of flooding in the Wollongong LGA this may not be able to occur. The SES will retain intelligence that identifies “hot spots” that lie within high hazard areas. These areas are identified at the end of this section. 6. What to consider. When deciding to evacuate the following should be considered. a. Predicted flood level and rate of rise. b. Rainfall situation and rainfall predictions. c. Condition of evacuation routes. d. Characteristics of the at risk population. e. Time of day. f. Likely duration of evacuation operations and time available to conduct evacuations. g. Likely duration of any isolation and preparedness of the community to cope with isolation. h. Condition of essential services 7. Voluntary Evacuations. Some people will make their own decision to evacuate earlier and move to alternative accommodation using their own transport. These evacuees will be advised, via the media, to inform the Police or SES of their evacuation and their temporary address. Where possible, people F-2

will be given the opportunity to evacuate voluntarily at an early stage of a potentially severe flood. Elderly people and mothers with young children will especially be encouraged to evacuate voluntarily under such circumstances. 8. Evacuation triggers. a. Failure of Essential Services. The failure of public utilities such as sewerage, power, telephones and water pose a significant health risk to residents on the floodplain or in flood affected areas. In the event of any or all of these systems failing or potentially failing, the need for evacuations will be discussed with the members of the LEMC. b. Flooding affecting properties. Evacuations are to occur, if it is likely properties will be flooded. (See Community cards for Trigger levels/rainfall) c. Isolation of properties. Persons who are not prepared for isolation or unsuited due to medical conditions etc, should be encouraged to evacuate d. Dam Failure. Evacuations are to occur when advised of Imminent Dam failure Groupings and Tasks 9. Operational Sectors. For the purpose of managing flood response operations and evacuations during severe floods the Wollongong Local Government Area will be divided into operational sectors based on the flood plain management areas. 10. Tasks. Tasking will align with the agreed responsibilities as outlined in Part 2 – Responsibilities. Phase 1 – Warning 11. Evacuation Warnings. On receipt of flash flood warnings or observations predicting rainfall that may result in flooding, public health concerns or prolonged isolation, the Local SES Operations Controller will consult as necessary to determine the level of the threat and the need to consider evacuations. As soon as possible after the decision to evacuate is made, the Local SES Operations Controller will issue evacuation warnings to the „at risk‟ residents, indicating what people should do before evacuating and when actually doing so. 12. Content of Evacuation Warnings/Orders will include: a. The rainfall situation and the state of tributaries. b. The condition of transport routes. c. Location of evacuation shelters 13. Dissemination of Evacuation Warnings. These are disseminated via: a. The radio and TV stations listed in Annex E. b. Door-knocks by emergency service personnel. c. Public address systems from emergency service vehicles. d. Telephone. e. SES Flood Bulletins.

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan F-3

Phase 2 – Withdrawal 14. Introduction. Withdrawal involves the actual removal of the community/individuals from dangerous or potentially dangerous areas to safer areas. 15. Movement. Evacuees are to be encouraged to move using their own transport where possible. The Local SES Operations Controller will arrange transport for those people without their own vehicles. This may include the provision of buses. Evacuees will be taken or advised to go to the nearest accessible Assembly Point or Evacuation Centre. Evacuees who cannot reach an evacuation centre unaided will be transported from their homes or from designated assembly points nearby. 16. Phasing/Priority. In evacuations priority will be given to assist in the movement and management of people. These priorities will be determined at the time of the operations and are dependent upon many circumstances. 17. Traffic Control. When large-scale evacuations are likely, evacuation routes are to be secured by the NSW Police and kept clear by the following means: a. Denying access to all traffic except for emergency vehicles (including buses and private vehicles being used for the purposes of evacuation). b. Keeping one lane clear at all times for use by emergency vehicles. c. Positioning a tow truck or similar vehicle at appropriate entry points, road blocks and exit points along the evacuation routes. 18. Evacuation routes. Most roads within the Illawarra become quickly inundated from creek overflows as well as storm water drain spill. Due to the possibility of storm water drain spill occurring in any area it is difficult to pre-define evacuation routes within this plan. Therefore evacuation route advice will be provided according to intelligence gathered at the time of the event. 19. Special Needs Groups. A large number of elderly persons and tourists reside in urban areas of the Wollongong Local Government Area. When evacuations are ordered Ambulance Service personnel will be deployed to assist with the safe evacuation of these people. 20. Animals. Evacuees with their own transport will be encouraged to take their pet such as cats, dogs and horses with them as they evacuate. These animals will therefore be transported by car, truck or horse float along the evacuation routes designated in this plan. Animals so shifted will be collected from their owners at evacuation centres and taken to pre-arranged facilities. Due to safety restrictions, it may not be possible to allow animals to accompany their owners when being transported via aircraft or flood rescue boats. In these cases, provision will be made for animals to be picked up as the people are evacuated. Arrangements will also be made to pick up animals that are left behind. Assistance animals (guide dogs, hearing assistance animals, etc), however, will remain in the care of their owners throughout the evacuation. This includes transport and access into evacuation centres. 21. Doorknocking. Field teams conducting doorknocks will record and report back the following information back to the Operations Centre: a. Addresses and locations of houses doorknocked and/or evacuated. b. The number of occupants.

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan F-4

c. Details of the location evacuees are intending to present at. d. Details of how the evacuees will register. e. Details of support required (such as transport, medical evacuation, assistance to secure house and/or property and raise or move belongings). f. Details of residents who refuse to comply with the evacuation order. 22. Properties, which have been doorknocked, should be marked with survey tape. Written on the survey tape should be the name of the doorknocking unit and the time of doorknock. 23. Refusal to Evacuate. Field teams should not dedicate additional time dealing with people who are reluctant or refuse to comply with any evacuation order. These cases should be referred to the Local Emergency Management Operations Controller who will arrange for Police to ensure their evacuation. 24. Security. The NSW Police will provide security for evacuated premises. Details of evacuated premises are to be passed to the Wollongong and Lake Illawarra Police stations. 25. Transport and storage. Transport and storage of furniture from flood threatened properties will be arranged as time and resources permit. Phase 3 – Shelter 26. Evacuation Centres. The usual purpose of evacuation centres is to meet the immediate needs of victims, not to provide them with accommodation. Evacuees will be advised to go to or be taken to the nearest accessible evacuation centre, which may initially be established at the direction of the Local SES Operations Controller but managed as soon as possible by the Welfare Services. Any of the following sites may be suitable as evacuation centres: 27. Action on arrival. On arrival, evacuees will be: a. Registered; b. Medically checked, if necessary; and c. Provided with their immediate welfare needs. 28. Registration. The NSW Police are responsible for the registration of evacuees. Phase 4 – Return 29. Once it is considered safe to do so, the Local SES Operations Controller will authorise the return of evacuees to their normal or alternative place of residence. This decision will be made in consultation with appropriate. 30. The return will be controlled by the Local SES Operations Controller and may be conducted, at his/her request, by Welfare Services Evacuation Areas (“Hot Spots”) The following locations will be monitored by SES as to determine if evacuations will be required. Only in extreme rainfall events will SES consider evacuations.

ANNEX G - ARRANGEMENTS FOR THE EVACUATION OF CARAVAN PARKS AND THE RELOCATION OF CARAVANS

General 1. The following caravan parks are flood liable: a. Corrimal Beach Tourist Park b. Oasis Caravan Park c. Lake Illawarra Village d. Oaklands Village e. Figtree Gardens, Prince Hwy, Figtree

Advising Procedures 2. Caravan Park proprietors will be encouraged to ensure that the owners and occupiers of caravans are: a. Made aware that the caravan park is flood liable by:  Handing a printed notice to occupiers taking up residence.  The notice should indicate that the caravan park is liable to flooding and outline the evacuation and van relocation arrangements as detailed in this Annex. b. Displaying this notice prominently in each van. Made aware that if they are expecting to be absent from their vans for extended periods, they can:  Provide the manager with a key; in a sealed envelope; to the van.  Provide a contact address and telephone number.  Inform the manager if a vehicle will be required to relocate the van during flood time.  Leave any mobile van in a condition allowing it to be towed in an emergency (ie: tyres inflated, jacks wound up, personal effects secured and annexes and lines for water, sewer, electricity and gas readily detachable). c. Informed when a flood is rising. At this time, occupiers will be advised to:  Ensure that they have spare batteries for their radios.  Listen to a local radio station for updated flood information.  Prepare for evacuation and van relocation. 3. The Local SES Operations Controller will ensure that the managers of caravan parks are advised of flood warnings and the details of any evacuation order.

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan G-2

Evacuation of Occupants and Relocation of Vans 4. Caravan park proprietors will be encouraged to install flood depth indicators and road alignment markers within their caravan parks. 5. When an evacuation order is given: a. Occupiers of non-movable vans should:  Secure their vans by tying them down to prevent flotation.  Isolate power to their vans.  Collect personal papers, medicines, a change of clothing, toiletries and bedclothes.  Lift the other contents of their vans as high as possible within the van.  Move to a designated evacuation centre if they have their own transport, or move to the caravan office to await transport. b. Where possible, vans that can be moved will be relocated by their owners. Park managers will arrange for the relocation of mobile vans whose owners do not have a vehicle. Council and SES personnel may assist if required and may be able to provide additional vehicles. 6. Occupants of vans that are being relocated should go to a designated evacuation centre if they have their own transport. Those without their own transport are to report to the caravan park office. 7. Caravan park managers should: a. Ensure that their caravan park is capable of being evacuated within the following times.  Corrimal Beach Tourist Park – 3 hours  Oasis Caravan Park – 6 hours  Lake Illawarra Village – 6 hours  Oaklands Village – 6 hours  Figtree Gardens – 3 hours b. Advise the Local SES Operations Controller of:  The number of people requiring transport.  Details of any medical evacuations required.  Whether additional assistance is required to effect the evacuation. c. Check that no people remain in non-removable vans that are likely to be inundated. d. Inform the Local SES Operations Controller when the evacuation of the caravan park has been completed. e. Provide the Local SES Operations Controller with a register of people that have been evacuated. 8. Caravan parks south of the Wollongong Catchment, due to the short warning time available, should concentrate on the evacuation of persons rather than vans.

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan G-3

9. The Local SES Operations Controller, using Council resources as necessary, will advise when it is safe for the caravan parks to be re-occupied.

Return of Occupants and Vans 10. Vans will be towed back to the caravan parks by van owners or by vehicles and drivers arranged by the park managers. Again, Council and SES personnel will assist if available.

ANNEX H - THE MANAGEMENT OF COASTAL EROSION Background 1. The Wollongong City Council area is bordered by the Pacific Ocean to the east. There are three main types of beach units within the LGA‟s boundaries: compartmentalised, sheltered, and exposed. The coastal areas are subject to natural coastal processes and resultant coastline hazards that include coastal erosion, oceanic inundation, and shoreline recession. 2. The coastal erosion/oceanic inundation problem in the Wollongong City LGA takes two forms: a. Undercutting of dunes on their seaward sides, threatening the collapse of dwellings and other infrastructure b. The potential breaking through of the dunes by sea water, causing flooding and isolation of property on the landward side of the dunes 3. The most severe problems of coastal erosion/inundation occur as a result of oceanic storm conditions associated with the passage of ex-tropical cyclones and temperate-zone low-pressure systems. These storms may cause temporary sea level rises with large associated waves. The worst erosion/inundation is likely when severe weather conditions occur in conjunction with high tides At Risk Beaches 4. The following are classified as “Hot Spots” for coastal erosion within the Wollongong City LGA: Beach Name Risk Beach Name Risk

Stanwell Park Extreme Cliffs between Stanwell Park & Coalcliff Medium Coalcliff Extreme Coledale Beach Medium Thirroul Extreme Sandon Point Beach Medium Bellambi Point Extreme Bellambi Point Medium Flagstaff Point Extreme North Wollongong Beach Medium Wollongong (South Beach) Extreme Belmore Beach Medium Wollongong Extreme Red Point Medium Sharkey Beach High Port Kembla Harbour High

Table 7: Erosion risk levels of beaches Concept of Operations 5. Control. The SES is the designated combat agency for damage control from storms, including coastal erosion from storm activity. 6. Evacuation arrangements for Wollongong City LGA are contained in Annex F. 7. Within this role and as specified under the State Storm Plan the SES is responsible for the following during and in the period immediately prior to a storm event occurring out at sea:

Wollongong City Local Flood Plan, June 2010, Sub-Plan of Wollongong City Local Disaster Plan H-2

a. Advising the community at risk of the likely problem and actions they should take; b. The protection of life through the warning and evacuation of residents at risk; and c. The coordination of the lifting and/or relocation of readily movable household items and commercial stock and equipment. 8. The role of the SES as the combat agency for storms does not include coastal erosion and inundation caused by astronomical high tides when severe weather is not actually developing or occurring. 9. The SES is not responsible for controlling or conducting any physical mitigation works to protect properties or structures at risk from coastal erosion/inundation, either during or outside the period of storm activity. This includes, but is not limited to: a. The placement of rocks or other materials on beaches or foreshore areas b. The construction of temporary walls made of sandbags, geo-technical tubes, or other material 10. DECC will provide ongoing advice to local councils and coastal zone management committees on the formulation and implementation of coastal zone management plans including procedures for addressing coastal processes, coastline hazards and risks, management options and coastal policies. 11. BoM will issue Severe Weather Warnings.

NOTE: dam owners should take every attempt to call SES State Operations in the first instance and only use the SEOC if the SES cannot be contacted The ‘000’ emergency contact number is not the preferred method of contacting the NSW Police in the context of dam failure. It is likely that the ‘000’ operators will have difficulty dealing with the very unusual case of potential or actual dam failure. If ‘000’ is used, the caller must give the details of the incident to the ‘000’ operator before asking to be transferred to the duty Operations Inspector (DOI).
