5 1. Introduction 1.1 APPLICATION This Flood Response Plan (FRP) has been prepared for the Eastern Golf Club situated at Victoria Road, Yering. It guides the response of the Golf Club Manager to flooding from the Yarra River and aims to reduce the risk to life and property at site during a flood event. 1.2 THE PROPERTY The Eastern Golf Club is located to the east and in very close proximity to Yering Gorge on land that includes the left bank floodplain of the Yarra River (see Figure 3.1). A portion of the golf course and a section of the main access road are located on flood liable land. A more detailed description of the property and associated facilities is provided in Section REASON FOR THIS FLOOD RESPONSE PLAN Preparation of this FRP is a condition of Melbourne Water s consent 1 (reference ) to development of the Eastern Golf Club and associated facilities. The Plan therefore applies to all successors in title and lease of the land. This FRP has been prepared to the satisfaction of Melbourne Water and the Shire of Yarra Ranges. 1.4 WHAT THIS FLOOD RESPONSE PLAN AIMS TO ACHIEVE The FRP provides a means of managing existing as well as future flood risk at the Eastern Golf Club. It details the measures that need to be implemented in relation to the continued operation and future development of the site to ensure best possible preparedness as well as appropriate response and recovery measures (ie. those things that need to be done before, in the lead up to, during and after a flood the planning, training, monitoring, warning and evacuation procedures and accountabilities) in the event of a significant flood along the Yarra River. The FRP recognises and is structured to operate independently of but with due regard for: Existing flood forecast and warning services for the Yarra River and its tributaries as currently provided by the Bureau of Meteorology in conjunction with Melbourne Water; Local flood response activities initiated by the Shire of Yarra Ranges and / or VICSES (as the Control Agency for flood response) under the Shire of Yarra Ranges Municipal Emergency Management Plan (MEMP) Flood Emergency Plan or other plans as applicable; and Provisions of the Victorian Occupational Health and Safety Act 2004 and particularly Section 21. It follows that the purpose of this FRP is to guide the Responsible Person 2 (or his / her delegate) in the maintenance and application of flood response procedures so as to manage flood risk at the Eastern Golf Club by facilitating: A timely and effective response in the event of a Yarra River flood and in so doing maximise the safety of individuals and property (ie. minimise the threat to life and property of staff and visitors to the site) without increasing reliance on emergency service personnel; The effective functioning of the site during small flood events and the restoration of its functionality as quickly as possible after a severe Yarra River flood event; and The identification and documentation of operational, maintenance and other responsibilities in relation to flooding associated with the long term use of the site. 1.5 THE VICTORIA OH&S ACT (2004) AND THIS FLOOD RESPONSE PLAN In order to address the requirements of the Victorian OH&S Act (2004) (particularly the provisions of Section 21) and successor legislation, it is essential that the Responsible Person and his / her delegate maintain a high degree of 1 As the Floodplain Management (or Referral) Authority for the property pursuant to Section 56 (1) of the Planning and Environment Act The Responsible Person is the functional Manager of the Eastern Golf Club at Yering.

6 familiarity with the content and operation of this FRP. This familiarity would ideally have been gained through active involvement in: Establishing and exercising the procedures that support this FRP; Periodic training activities involving on-site staff; and Driving routine review of procedures and associated tools. 1.6 MANAGEMENT OF THIS FLOOD RESPONSE PLAN This FRP has been and is to remain incorporated, as a stand-alone loose-leaf insert, into the risk management, OH&S and incident management framework for the Eastern Golf Club and will be managed by the Responsible Person. A bulleted summary of the Responsible Person s responsibilities with respect to this FRP is provided at Appendix E. 1.7 USING THIS FLOOD RESPONSE PLAN This FRP takes account of the full range of floods that could reasonably be expected to occur in the vicinity of the Eastern Golf Club. Essential elements relating to response in the event of a flood that affects the golf course and associated facilities at the Eastern Golf Club have been captured to a Flood Action List. This Action List is provided at Appendix A. 1.8 MAINTENANCE OF THIS FLOOD RESPONSE PLAN This FRP must be maintained as a live document. This means that it must be reviewed routinely and updated as new information comes to hand and also as a result of learning from experience with its application during flood events (see for example Sections 2, 4, 5, and 6) The importance of this FRP and its maintenance should not be under-estimated. It is a fundamental principle of emergency management that communities that have thought about a problem and planned for it beforehand are able to cope better than those who have ignored it and hoped it would never occur. Further, it should be clearly understood that part of the land occupied by the Eastern Golf Club and a section of its main access road has been inundated by Yarra River flood waters in the past and will be flooded again at some time in the future. An effective FRP will be critical to the safety of life and property during such events. Michael Cawood & Associates Pty Ltd DocNo MCA0177/030_FRP V2.4 August 2011 Page 2 of 30

8 2. Requirement for a Flood Response Plan 2.1 GENERAL The Eastern Golf Club is situated on private land to the east and in very close proximity to Yering Gorge on land that includes the left bank floodplain of the Yarra River (see Figure 3.1). The development comprises a range of recreational facilities, a function centre and sales area, access road and parking areas, water reticulation system including pumps and lagoons, a maintenance compound, and buildings associated with a dwelling and group accommodation. A portion of the golf course, a section of the main access road and a short length of the emergency evacuation route are located on flood liable land which is identified in the Shire of Yarra Ranges Planning Scheme 3 as subject to inundation through a Land Subject to Inundation Overlay (ie. LSIO). However, the emergency access route is a minimum of 100mm above the declared 1% AEP 4 flood level at site, the car park is a minimum of 600mm above the declared 1% AEP flood level and the Clubhouse and maintenance compound are located outside the 1% AEP flood extent with main floor levels more than 600mm above the declared 1% AEP flood level. Note that while the floor level of the Clubhouse basement is below the 1% AEP flood level, access to the basement is set at 600mm above the 1% AEP flood level. Victoria Road, a sealed good quality Shire-maintained road, provides a safe egress route to the south towards Lilydale during severe floods as it is above the Yarra River 1% AEP flood level (ie. outside the Yarra floodplain and the area subject to the LSIO). 2.2 LIKELY FLOOD IMPACTS AND KEY LEVELS The declared 1% AEP flood level at site is 70.40m AHD. Parts of the golf course and the basement of the Clubhouse together with a section of the main access road are situated below this level (see Figure 1.1). For example: At around 65.0m AHD, the lowest green is approximately 5.4m lower than the declared 1% flood level; and At around 67.0m AHD, the lowest point along the main access road is approximately 3.4m lower than the declared 1% flood level. Statistically, this means that there is an approximate 5% chance that the lowest point along the main access road could get wetted by flood waters in any one year. Under 1% AEP (ie. severe) flood conditions it is conservatively expected that the Yarra River would begin to rise in the vicinity of the Eastern Golf Club some considerable time around hours - after the start of heavy and prolonged rainfall and around the same time as or a little after the first flood warning for the Yarra River around Yarra Glen was issued by the Bureau of Meteorology in conjunction with Melbourne Water. The river would then rise relatively quickly from normal levels. Key river levels and times to rise for the Eastern Golf Club site following heavy and prolonged rainfall are listed in Table 2.1. This information has also been captured to the Action List at Appendix A. Note that: a) Smaller floods will rise more slowly than larger floods (see note at the end of Section 4.3) and thus more slowly than indicated in Table 2.1. b) Due to the size and shape of the Yarra River catchment, flood waters are likely to be still rising at Yarra Glen and in the vicinity of the Eastern Golf Club after the rain that caused the flood has passed: just because it has stopped raining does not mean that flood waters won t continue to rise. 3 The site is zoned as Green Wedge- Schedule 4 (GWZ4) in the Shire of Yarra Ranges Planning Scheme. The whole site is also covered by a Significant Landscape Overlay (SLO) while a Land Subject to Inundation Overlay (LSIO) covers around half the site. Parts of the site nearest the Yarra River are covered by an Environmental Significance Overlay (ESO) and a small part adjacent to the river is also covered by an Erosion Management Overlay (EMO). 4 Annual exceedance probability (AEP) is the inverse of average recurrence interval (ARI), expressed as a percentage. In terms of flooding, it is the likelihood of occurrence of a flood of a given size or larger in any one year. Hence the 1% AEP event is the same as the 100-year ARI event. Michael Cawood & Associates Pty Ltd DocNo MCA0177/030_FRP V2.4 August 2011 Page 4 of 30

9 c) The velocity of flood waters at site near the main channel of the Yarra River is expected to increase from slow during smaller floods to moderate during larger floods and remain slow at other locations on site 5 : do not attempt to wade or drive through flood waters - it is dangerous as you may unexpectedly lose your footing and / or be swept off your feet and most vehicles begin to become unstable in water that is more than 300mm deep. d) In the event of a flood of sufficient severity to threaten the golf course and associated facilities, it is highly likely that the Bureau of Meteorology, in conjunction with Melbourne Water, will already have issued flood warnings for the Yarra River in the vicinity of Yarra Glen and perhaps also for the Watts River at Healesville as well as for other creeks and streams in the Yarra Valley. Further, a large number of public and private assets along the river through the Yarra Valley and downstream will either have been flooded or will be evacuated and / or closed in anticipation of flooding.

This Flood Response Plan is aimed at addressing that risk. 5 This is a direct consequence of local topography and the location of the site relative to the Yarra River s main flow channel.

11 4. Preparedness for Flood 4.1 WHAT HAS BEEN DONE ALREADY Initial Damage and Flood Risk Reduction Measures Susceptibility of the Eastern Golf Club and associated facilities to flood damage has been contained by: Locating the Clubhouse, function centre, sales area, service yard for the Clubhouse together with associated facilities, gas cylinders and the entrance to the Clubhouse basement, the maintenance compound, accommodation facilities and the Caretaker cottage outside the declared 1% AEP flood extent with floor levels (other than the Clubhouse basement) more than 600mm above the declared 1% AEP flood level; Locating the car park, tennis courts and associated lighting, the coaching area, the driving range and the practice greens and fairway, outside the 1% AEP flood extent and thus above the declared 1% AEP flood level; Locating the irrigation system 415V substation and on-site waste treatment plant within the maintenance compound and thus above the declared 1% AEP flood level; Using submersible transfer pump sets (ie. at the Yarra River and at the three irrigation storage lagoons in the eastern part of the golf course); Using a single run of cable (or cable with water-proofed joints) between control panels and pumps; Utilising low-voltage lighting bollards along the main access road from Victoria Road; and Installing composting toilets around the golf course above the declared 1% AEP flood level. In summary and as indicated by Table 2.1, the only key features located below the declared 1% AEP flood level are an approximate 400m long section of the main access road between the car park and Victoria Road, and a number of the tees, fairways and greens River Level Relationship A preliminary relationship (see Figure 4.1 repeated as Figure A1 in Appendix A) has been developed between the river gauge at Yarra Glen (located immediately upstream of the old Melba Highway Bridge at Yarra Glen) and levels at the Eastern Golf Club at Yering. This relationship enables flood levels at Yarra Glen (either as forecast by the Bureau of Meteorology in conjunction with Melbourne Water, obtained from Melbourne Water s website _data/rainfall_and_river_level _data.asp, the Bureau of Meteorology s website or read directly from the gauge) to be quickly and easily converted to levels directly relevant to the site. 9 The level indicated for the Eastern Golf Club will occur in the order of 1 to 2 hours after the corresponding level is reached at the Yarra Glen gauge during large floods and longer during smaller floods Approx lowest point (70.5m AHD) along emergency evacuation route River level at Yarra Glen (m) Approx level of lowest greens Lowest point along main access road (67.0m AHD) Close main access road 1% AEP flood level at Eastern Golf Club (70.40m AHD) 5 5.0m major flood level 4.5 Sept10 flood 4.57m 4.5m moderate flood level Oct09 flood 4.44m 4.1m minor flood level Water level at the Eastern Golf Club (m AHD) Feb11 flood 4.77m Figure 4.1: Preliminary relationship between river levels at Yarra Glen and the Eastern Golf Club at Yering Michael Cawood & Associates Pty Ltd DocNo MCA0177/030_FRP V2.4 August 2011 Page 7 of 30

12 The time lag between levels being experienced at Yarra Glen and at the Eastern Golf Club site are likely to be in the order of one (1) to two (2) hours during large floods and longer during smaller floods. NOTE The river level relationship should, if and as possible, be verified, updated and expanded following flooding at site Access to Flood Warnings and Rain and River Data Flood warnings 6 for the Yarra River and other watercourses are broadcast by the electronic media (ie. radio and TV particularly 774 ABC radio) and are available from the Bureau of Meteorology s website ( along with weather radar and satellite images and updated rain and river level information for key locations. Data for a number of rainfall and river level gauge locations around Melbourne, including at Yarra Glen, can be obtained from Melbourne Water s website ( /rivers_and_creeks/rainfall _and_river_level_data/rainfall_and_river_level_data.asp). Information about flooding, including all current Bureau-issued flood warnings is also available from the VICSES website ( The level of the Yarra River can also be read directly from the Yarra Glen gauge. However, this could be hazardous when the river is in flood and is not recommended Flood Advisory Signs Temporary Signs Wording to be firmed up when signs ordered Two WATER OVER ROAD signs are stored at the maintenance compound. The signs are yellow with black text. Signs should be placed either side of the expected area of flooding whenever the river level at Yarra Glen is forecast to (or does) exceed 5.5m. Refer to the Flood Action List at Appendix A. Two ROAD CLOSED USE ALTERNATIVE ROUTE signs are stored at the maintenance compound. The signs are yellow with black text. Signs should be placed on the main access road at both ends of the emergency evacuation route in a manner that directs road users onto the alternative route (see Section and Figure 4.4) whenever the river level at Yarra Glen is forecast to (or does) exceed 5.6m. Refer to the Flood Action List at Appendix A Permanent Signs Permanent flood advisory signs (see Figure 4.2) have been erected on both sides of the main access road above the flood depth indicator boards (see Section 4.1.5) and face on-coming traffic. The signs are white with black text and state: ROAD SUBJECT TO FLOODING Flood Depth Indicator Boards Flood depth indicator boards (see Figure 4.3) have been erected at the following locations: On both sides of the main access road so as to face on-coming traffic: At the beginning of the low section (ie. at 67.0m AHD) at around 420m from the main entrance between the 24 th fairway and the irrigation storage lagoon near the 21 st green (to 1m with road level ~ 0.00m); and At the end of the low section (ie. at 67.0m AHD) near the southern end of the irrigation storage lagoon between the 20 th and 24 th fairways at around 585m from the main entrance (to 1m with road level ~ 0.00m). Each board is 1m long with 0.00m at road level and is mounted on an approx 50mm diameter galvanised pipe firmly located in the ground. The permanent flood advisory signs (see Section ) are mounted above the flood depth 6 Minor flood warnings will have been issued for the Yarra River if the river level has or is expected to exceed 4.1m at Yarra Glen. Moderate flood warnings are issued if this level has or is likely to exceed 4.5m and major flood warnings are issued if the level has or is expected to exceed 5.0m.

13 indicator boards. The boards and signs are both positioned to face on-coming traffic. Photos be added following installation Figure 4.2: Flood advisory signs either side of the main access road Photos be added following installation Figure 4.3: Flood depth indicator boards either side of the main access road at either end of the low section Emergency Evacuation Route An emergency evacuation route that avoids the low point along the main access road has been established (see Figure 4.4 repeated as Figure A2 in Appendix A). The route utilises golf cart and maintenance paths and will remain dry for flooding up to 100mm above the 1% AEP event (ie. 8.6m at the Yarra Glen gauge see Appendix A). The evacuation route starts from the western side of the car park opposite the Clubhouse and follows the path that runs between the 1 st and practice fairways towards the southern boundary fence and then bends to the left to follow the boundary fence to the east and Victoria Road. The path crosses over the pipes that provide drainage relief for the wetland and bends to the left to run alongside the 21 st fairway before joining the main access road near the main gate. An alternative evacuation route starts from the main access road to the east of but close to the road into the Michael Cawood & Associates Pty Ltd DocNo MCA0177/030_FRP V2.4 August 2011 Page 9 of 30

It runs towards the southern boundary fence and in front of the 20th tee and joins the other evacuation route as it follows the boundary fence to the east and Victoria Road. The evacuation routes can be used by full sized vehicles, including a fully laden CFA fire truck, and is shown as lilac on Figure 4.4. Figure 4.4: Emergency evacuation routes along golf cart and maintenance paths shown as lilac Flood Response Plan Outline of Flood Response Plan This Flood Response Plan (FRP) has been prepared to detail measures that need to be taken to ensure best possible preparedness as well as appropriate response and recovery measures (ie. those things that need to be done before, in the lead up to, during and after a flood the planning, monitoring, warning and evacuation procedures and accountabilities) in the event of a significant flood along the Yarra River. These measures are aimed in particular at effectively maximising the safety and well being of staff and visitors to the Eastern Golf Club in times of significant flood. The FRP takes account of the full range of floods that could reasonably be expected to occur at site. The FRP does not address stormwater flooding resulting from intense local rainfall as, due to the location and general slope of the site on the left hand bank of and in close proximity to the Yarra River, it is not considered a credible risk (see Section 2.3). This FRP has been and is to remain incorporated, as a stand-alone loose-leaf insert, into the risk management, Michael Cawood & Associates Pty Ltd DocNo MCA0177/030_FRP V2.4 August 2011 Page 10 of 30

15 OH&S and incident management framework for the Eastern Golf Club and as such is subject to routine review as part of that framework Flood Action List A Flood Action List is provided at Appendix A. The list is a summary of this FRP in terms of key levels and actions Clear Responsibility Responsibility for the implementation and maintenance of this Plan rests with the Responsible Person Flood Awareness - Regular Briefing Sessions and Regular Exercises Regular (ideally once per year with the first one occurring within 1 month of this Plan being adopted) a flood response briefing session will be conducted for all relevant on-site personnel (see Section 4.2.2). As a minimum, the information sessions will outline the details of this Flood Response Plan including roles and responsibilities with respect to flood warning, evacuation, and recovery. Consideration could be given to inviting local emergency preparedness and response personnel (eg. Council s MERO, VICSES, Police) to participate in and contribute to these sessions. It is the responsibility of the Responsible Person or his / her delegate to coordinate and facilitate the briefing sessions. The Eastern Golf Club staff induction process will also include reference to flood response procedures. 4.2 WHAT NEEDS TO BE DONE EACH YEAR OR MORE FREQUENTLY Maintenance of the Flood Response Plan This FRP must be maintained in order to remain effective. As a minimum, this will involve the following: Formal allocation of responsibility for the maintenance of this FRP to the Responsible Person; Formal review of this FRP by the Responsible Person on initial commissioning and thereafter annually (or more frequently if deemed appropriate) in order to determine: Currency: FRP is up-to-date and able to be implemented; All links from and to other procedures and plans are correct, valid and viable; All contact details at Appendix B (names, telephone numbers business and after hours, addresses if required, etc) are correct and that the list is complete. Applicability With particular attention to any changed conditions at site since the last review. Availability and accessibility Of the FRP and all signs, flood depth indicator boards and other materials that support and / or are necessary to implement this FRP (see Section 4.1). Presence and continued good condition of the FRP and associated procedures; Flood advisory signs (see Figure 4.2); Flood depth indicator boards (see Figure 4.3) Annual review and rework of the Flood Action List at Appendix A. Formal sign-off on the review with notation of any changes made and any required follow-ups along with the name and position of the responsible person (see Appendix C). It is also suggested that periodic risk assessments undertaken as part of the risk management, OH&S and incident management framework for the Eastern Golf Club, should include consideration of flooding with due regard for this FRP. Any outcomes of any actions arising from such assessments must be reflected in this FRP and / or successor Plans. 7 The Responsible Person is the functional Manager of the Eastern Golf Club at Yering.

16 4.2.2 Maintenance of Flood Awareness Periodically (ideally once per year and perhaps as an extension to formal fire exercises), the Responsible Person or his / her delegate will conduct a flood response briefing session for all relevant on-site personnel (see Section ). As a minimum, the information session should outline the details of this FRP including roles and responsibilities with respect to flood warning, evacuation, and recovery: what the Responsible Person or his / her delegate and staff need to do before, during and after a flood event that is either forecast to or does exceed 5.0m (major flood level) at the Yarra Glen river gauge (ie. around 65.0m AHD at the Eastern Golf Club) Maintenance of the Wetland Outlet Pipes At least every six months and after every heavy rain and flood event, the wetland overflow pipes that pass under the emergency evacuation route must be checked to ensure there are no blockages or restrictions that may affect the free flow of water through the pipes. While the pipes have been designed to maintain a balance between upstream and downstream levels with up to 50% blockage, any debris or other material blocking any part of the pipe crosssection or otherwise affecting the free flow of water through the pipes, must be removed as soon as reasonable practical. 4.3 WHAT NEEDS TO BE DONE AFTER EACH FLOOD After each flood that that exceeds 5.0m on the Yarra Glen river gauge (ie. around 65.0m AHD at the Eastern Golf Club) and triggers the procedures detailed in this FRP, the Responsible Person must initiate a review and update as appropriate of: The effectiveness and appropriateness of the standard operating and associated procedures established for flood this FRP (eg. is the FRP sufficiently complete, was contact timely and to the correct person, etc); The appropriateness and inclusiveness of instructions and information contained in this FRP with particular attention to Table 2.1 in Section 2.2 and to the Flood Action Plan and river level relationship at Appendix A (and also at Figure 4.1 in Section 4.1.2); and The adequacy of measures implemented at site to reduce the risk to life and property from flood. If the event inundated part of the Eastern Golf Club, the Responsible Person must: Arrange for the peak water level to be surveyed to AHD and for this and other related information (such as photographs and description of flood impacts and extents, the peak level at the Yarra Glen river gauge) to be recorded at Appendix D. Arrange for a sketch of the approximate flood extent complete with notes on flood characteristics (such as flow velocities, flow directions, dangerous areas, impacts, etc) to be prepared and attached to Appendix D. The Responsible Person must also refer to Section 6 of this FRP. NOTE While floods more frequent and thus smaller than the 1% AEP flood will rise more slowly and peak at lower levels than larger rarer floods, this FRP has been prepared to ensure the safety of staff and visitors to the Eastern Golf Club and to minimise flood related damage at site for the full range of floods that could reasonably be expected to occur. It is therefore possible that the response arrangements may appear excessively conservative under small to medium flood conditions. The temptation to relax response arrangements and adjust trigger levels should be strenuously avoided without appropriate professional and informed advice. Any and all changes to this FRP must be documented at Appendix C. Michael Cawood & Associates Pty Ltd DocNo MCA0177/030_FRP V2.4 August 2011 Page 12 of 30

17 5. What to do if a Flood Occurs the FRP 5.1 WHAT SIZE FLOOD WILL AFFECT THE EASTERN GOLF CLUB Flooding of the Eastern Golf Club will occur as a result of heavy and prolonged rainfall over the Yarra Valley as part of a large scale regional event rather than as a result of a smaller localised (eg. thunderstorm) event. Such an event would also lead to significant flooding around Yarra Glen and along the Yarra River through Warrandyte and downstream. Only those floods that are likely to exceed 5.0m at the Yarra Glen river gauge (~65.0m AHD at site 8 ) are likely to have an effect on normal operations at the Eastern Golf Club. A forecast or actual river level at Yarra Glen in excess of: 5.0m (major flooding see Table 2.1 and Figure A1) indicates that flood waters will wash the lowest green; 5.5m indicates that flood waters will begin to wet the lowest section of the main access road between the 24 th fairway and the irrigation storage lagoon adjacent to the 20 th fairway; 5.6m indicates that flood waters will be around 300mm deep across the lowest section of the main access road between the 24 th fairway and the irrigation storage lagoon adjacent to the 20 th fairway; 8.6m indicates that flood waters will begin to wet the lowest section of the emergency evacuation route (along golf cart and maintenance paths see Figure 4.4 or Figure A2) from adjacent to the 20 th fairway beside the boundary fence along Henley Road to just before it rejoin the main access road. Under 1% AEP type flood conditions (ie. severe flood conditions), it is expected that: The Yarra River would begin to rise in the vicinity of the Eastern Golf Club some considerable time around hours - after the start of heavy and prolonged rainfall and around the same time as or a little after the first flood warning is issued by the Bureau of Meteorology in conjunction with Melbourne Water; The Yarra River would rise from normal levels to just begin wetting the lowest point along the main access road (ie. around 67.0m AHD at site and 5.5m at Yarra Glen) in around 23 to 26 hours of river rises commencing and somewhere around 33 to 40 hours after the start of heavy and prolonged rainfall. The main access road would remain wet for around 40 to 48 hours The time lag between levels being experienced at Yarra Glen and at the Eastern Golf Club are likely to be in the order of one (1) to two (2) hours during large floods and longer during smaller floods. Smaller floods are however likely to fall at about the same rate as larger floods. See Section HOW WILL IT BE KNOWN THAT THE EASTERN GOLF CLUB IS LIKELY TO BE FLOODED Environmental indicators (eg. prolonged heavy rainfall and localised flooding of roads around Melbourne) will provide an indication that the lower parts of the golf course may be flooded. However, access to and egress from the Eastern Golf Club will only be genuinely threatened by major and more severe flooding at Yarra Glen and immediately downstream to Yering Gorge. In general this will only occur as a result of a significant period of heavy rain over the Yarra Valley (see Section 5.1 above). In such an event, it is highly likely that the Bureau of Meteorology, in conjunction with Melbourne Water, would have issued flood warnings for the Yarra River. In addition, a large number of public and private assets along the river would either have been flooded or would be closed and / or monitoring water levels closely in anticipation of flooding (eg. the Yarra Glen racecourse, Bulleen Road, the Veneto Club in Bulleen, bike paths and golf courses in the Chandler Basin, the Fairfield Boathouse, and so on). Media reports would also be focussing on flooding and related problems. Flood warnings for the Yarra River and other watercourses are broadcast by the electronic media (ie. radio and TV particularly 774 ABC radio) and are available from the Bureau of Meteorology s website ( along with weather radar and satellite images and updated rain and river level information for key locations including Yarra Glen. Data for a number of rainfall and river level gauge locations around Melbourne can also be obtained 8 This is the level at which flood water will begin to wash over the lowest green.

18 from Melbourne Water s website ( _level_data/rainfall_and_river_level_data.asp). Information about flooding, including all current Bureau-issued flood warnings is also available from the VICSES website ( See Section WHAT NEEDS TO BE DONE IF THERE IS MAJOR FLOODING IN THE YARRA RIVER On either hearing a flood warning for the Yarra River or observing flood waters beginning to encroach on to the golf course, the Responsible Person or his / her delegate should: Monitor all further flood warnings issued by the Bureau of Meteorology for the Yarra River; Monitor the Bureau of Meteorology s or Melbourne Water s website for actual and forecast levels for the Yarra River at Yarra Glen see boxed important notes below; and Maintain a heightened awareness of possible flood risk at site and of further flooding. A forecast or actual river level in excess of 5.5m at Yarra Glen indicates that flood waters will wash the lowest section of the main access road. This level (5.5m at Yarra Glen) is therefore the trigger for the Responsible Person or his / her delegate to attend site and complete the actions listed in Appendix A. IMPORTANT NOTES 1. Rising river levels at Yarra Glen indicate that river levels will also rise at the Eastern Golf Club. A rapid rise at Yarra Glen suggests an even quicker rise at the Eastern Golf Club. In larger floods, the actual increase in water level at the Eastern Golf Club will be more than at Yarra Glen due to the throttling effect of Yering Gorge and the resulting ponding that occurs across the floodplain immediately upstream. 2. An actual or forecast level of 5.5m at the Yarra Glen river gauge is the trigger for the Responsible Person or his / her delegate to attend site and complete the actions listed in Appendix A. 3. An actual or forecast level of 5.6m at the Yarra Glen river gauge is the trigger for the main access road to be closed and for all movements in and out of the site to be via the emergency evacuation route as per the action list at Appendix A. 4. Instructions on what to do when a flood threatens the Eastern Golf Club are summarised in Appendix A. These instructions involve restricting arrivals to and departures from the Eastern Golf Club in order to keep people and assets away from rising flood water and thereby ensuring the safety of staff and visitors and minimising flood related damage. 5. Contact details for key personnel and other stakeholders are provided in Appendix B. Michael Cawood & Associates Pty Ltd DocNo MCA0177/030_FRP V2.4 August 2011 Page 14 of 30

19 6. Recovery - After the Flood has Receded 6.1 RESUMPTION OF ACTIVITIES AT THE EASTERN GOLF CLUB As flood waters recede but not before the main access road has become clear of flood water, the Responsible Person or his / her delegate shall, as necessary: Arrange checking for correct and safe operation (and rectification as necessary) of all electrical power and other services (eg. sewer, water, electricity, security system, switches, power outlets, pumps, external lighting including bollards along the main access road, etc) that have been inundated; Arrange for the wetland overflow pipes that pass under the emergency evacuation route to be cleaned of blockages or restrictions that may affect the free flow of water through the pipes; Arrange for all flood debris and mud to be cleaned from all trafficked surfaces and areas; Arrange for the repair and / or replacement of damaged surfaces, equipment and materials in line with applicable standards and guidelines; Check all external hard surfaces (ie. lifting of the surface, pot holes, erosion / undermining at the surface edges, etc) for damage. Any damage likely to cause injury to staff and visitors must be appropriately isolated to minimise the possibility of injury or damage. Further, actions to repair damage must be initiated as quickly as possible; Check that all flood related signs and flood depth indicator boards are in good condition and legible and initiate any necessary repair or replacement actions; Clean and return WATER OVER ROAD and ROAD CLOSED signs to the Maintenance compound; Arrange for the survey of flood depths to AHD at various locations across the golf course and surrounds; Collect and collate photographs and other information on flood impacts and extents (see Sections 4.2.1, 4.3, 6.2, 6.3, 6.4 and 6.5); and Establish a date / time for resumption of partial / full activities at the Eastern Golf Club. The above checks on the integrity of hard surfaces should continue on a daily basis for a period of up to two weeks after flood waters have receded or as recommended by an appropriately qualified expert. 6.2 FLOOD RESPONSE PLAN REVIEW Following resumption of use and as soon after the passing of the flood as possible and certainly within four (4) weeks, all aspects of this Flood Response Plan and its implementation (particularly Appendix A, Appendix C, Appendix D and Figure 4.1,) must be reviewed by the Responsible Person (see Section 4.3). This review should involve all personnel with an active role in flood response at site. It is also suggested that appropriate Municipal, VICSES and other agency personnel could be invited to participate in the review. 6.3 MAINTENANCE OF FLOOD RECORDS The peak height of the flood as measured at various locations across the site along with any notes on flood behaviour and impacts should be recorded at Appendix D to this Flood Response Plan by the Responsible Person. Any photographs of the flood event should also be included at Appendix D. See also Section FLOOD ACTION LIST Following a flood event or as a result of changed conditions at or in the vicinity of the Eastern Golf Club, any changes to observed flood impacts and required actions at site as documented in this Flood Response Plan, particularly at Appendix A but also at Section 2.2 (see Table 2.1), must be captured to a revised version. Note however that the temptation to relax response arrangements and adjust trigger levels should be strenuously avoided without appropriate professional and informed advice. Any changes must be documented in this FRP at Appendix C. 6.5 RIVER LEVEL RELATIONSHIP The relationship developed between the Yarra Glen river gauge and levels at site (see Section 2.2, 4.1.2, Figure 4.1 Michael Cawood & Associates Pty Ltd DocNo MCA0177/030_FRP V2.4 August 2011 Page 15 of 30

20 and Appendix A) must be checked by the Responsible Person or his / her delegate after each Yarra River flood event. This may include adjustment as necessary and / or the addition of new information. Appropriate professional and informed advice should however be sought before changes are made.

Actions required Refer to Table 2.1 for guidance on the time it will take for flood waters to rise Responsible Person and / or delegate to: Advise any residents and all staff at site that: The main access road is likely to become impassable at the low section between the 24 th fairway and the irrigation storage lagoon adjacent to the 20 th fairway approximately 2 hours after the time the river is forecast to, or does, exceed 5.6m at Yarra Glen, due to flood water being more than 300mm deep; The main gates will be closed and ROAD CLOSED signs will be erected within 1 hour; If they intend leaving, They should check that water is no more than 300mm deep before driving through it; They should not drive through water that is more than 300mm deep; If they drive through flood water, they should do so at no more than 10km/hour and should dry their brakes after exiting the water; They may use the alternative evacuation route. Close the main gates and place ROAD CLOSED USE AERNATIVE ROUTE signs on the main access road at both ends of the emergency evacuation route in a manner that directs road users onto the alternative route. Maintain a heightened awareness of likely flood risk and of further rises at site. As required, advise key contacts (see Appendix B). Monitor flood warnings issued by the Bureau of Meteorology along with river levels every (say) 2 hours or so. Responsible Person and / or delegate to: Remind any residents and staff at site that the main access road is closed and impassable due to deep flood water and that the emergency evacuation route(s) will need to be used the path that begins at the western side of the car park opposite the Clubhouse, passes between the 1 st and practice fairways and then turns to the left along the boundary fence towards Victoria Road, crosses over the pipes that provide drainage relief for the wetland and around the 21 st tee to run alongside the 21 st fairway to the main access road near the main gate. Details of the alternative route (the path that leaves the main access road to the east of but close to the road into the maintenance compound and runs towards the southern boundary immediately in front of the 20 th tee to join the other route as it follows the boundary fence to the east and Victoria Road) should also be provided if require - see Figure A2. Check that the main gate is closed and that ROAD CLOSED USE ALTERNATIVE ROUTE signs are in place. Maintain a heightened awareness of likely flood risk and of further rises at site. As required, advise key contacts (see Appendix B). Monitor flood warnings issued by the Bureau of Meteorology along with river levels every (say) 2 hours or so.
