Condobolin floodplain risk management plan
Funding: $50,000 (SFMP)

Through this project, a management study and draft management plan will be prepared based on the 2008 flood study for Condobolin, which was adopted by the council in 2010. The council intends to use the outcomes of the draft management plan to consider possible mitigation measures for developments identified as being affected by flooding impacts. Suitable development control measures and details for possible new development within the town and its surroundings will also be provided in the draft plan. The current Condobolin Flood Plan prepared by the State Emergency Services and this proposed plan will be compared to ensure compatibility.

Lake Macquarie City Council

Jewells Wetland flood study
Funding: $40,000 (FRMGS)

The Jewells Wetland Catchment has a long history of flooding. Lake Macquarie's Floodplain Management Committee and council have resolved to prepare a flood study for the Jewells Wetland Catchment, to be undertaken and commenced during 2011-2012. The need for a flood study (and subsequent flood risk management strategy and plan) is driven by community pressure, including recognition of the significant environmental values of the downstream wetland system and the surrounding natural area. This is combined with the need to address flooding problems throughout catchment. The study area is also subject to urban development pressures in relation to large private landholdings adjacent to Redhead and Jewells townships, as well as upstream in the Windale/Mount Hutton townships.

Lake Macquarie Catchment integrated flood warning system
Funding:  $120,000 (FRMGS)

From 1986 to 2011, Lake Macquarie City Council undertook and endorsed five flood risk management strategies and plans over major prioritised catchments in its local government area. According to the plans for Stony Creek, Cockle Creek and Lake Macquarie Waterway, the critical duration and response times for flooding in the lower reaches of each catchment meant the implementation of a flood warning system for each catchment is warranted. This Emergency Response Modification Project includes investigation, concept design, and implementation and installation of an integrated flood warning system for Lake Macquarie Catchment. This flood warning system incorporates the existing telemetered flood warning system at Kalang Road and Dora Creek, Bureau of Meteorology flood warnings, and an expansion of the flood monitoring network to some, or all, of the above mentioned catchments (subject to analysis of the joint probability of flooding in adjacent catchments).

Winding Creek flood study
Funding:  $25,000 (FRMGS)

The Winding Creek Catchment has a long history of flooding. Lake Macquarie's Floodplain Management Committee and council have resolved to prepare a flood study to address flooding problems throughout the catchment. The catchment was impacted on by a major flood event during the June long weekend of 2007, causing major damage to infrastructure and disruption to parts of the Cardiff commercial centre for many months after the event. The study area is subject to major urban development pressures in relation to large government/private landholdings at Glendale township, which include the strategic concept to relocate Lake Macquarie City Council’s entire civic precinct, as well as developing a large area of residential land upstream of Brush Creek at Glendale adjacent to Cameron Park.

Review of Dora Creek Flood Study (1986) and Dora Creek Flood Risk Management Strategy and Plan (1998), to incorporate climate change
Funding:  $80,000 (FRMGS)

Dora Creek is located 30 km south-west of Newcastle. Dora Creek township, located 3 km from the mouth of the creek, has developed at a rapid rate in recent years. Significant flooding of Dora Creek has been experienced on several occasions, including recorded floods in 1927, 1949, 1953, 1962, 1974, 1977, 1978, 1981, 1989, 1990 and 2007. The area covered by this project is the floodplain of Dora Creek from the junction of Stockton Creek to its confluence with Lake Macquarie waterway. Flooding results from heavy rainfall over the Dora Creek catchment and its tributaries.

The project will:

  • review and upgrade the flood study, and hazards and hydraulic categories
  • assess climate change and sea level rise impacts on flooding
  • reassess the management options and strategies taking into consideration climate change and sea level rise.

Leichhardt Municipal Council

Leichhardt flood study and flood risk management study and plan
Funding: $160,000 (SFMP)

The floodplain risk management study and plan follow on from the Leichhardt Flood Study. The council completed the draft Leichhardt Estuarine Planning Levels Study which was funded under the state's Estuary Management Program. The study established storm inundation levels along the entire Leichhardt foreshore. Due to the intrinsic link between the floodplains of the Leichhardt local government area and tidal and wave inundation from Sydney Harbour, it is proposed to address both forms of flood risk in the flood risk management strategy and plan.

Lithgow Council

Lithgow flood study review
Funding: $120,000 (SFMP)

This project will review the out-of-date 1980s flood study and the 1992 floodplain risk management plan, to account for new development, update the models and consider the flood risk from the full range of floods. The proposed flood study will also include a preliminary assessment of climate change impacts, and provide design flood levels, flood velocities and flood hazard categorisation for various flood events including 100-year and probable maximum flood events.

It is also proposed to establish a 2D/1D flood model for the study area. The council does not have airborne laser scanning data and this will be required for the flood modelling. The 2D model will allow the council to revise flood behaviour following construction of Stage 1 of major flood mitigation works at Farmers Creek. Following the completion of a flood study, a flood risk management strategy and plan will be prepared.

Lockhart Shire Council

Lockhart floodplain risk management study and plan
Funding: $81,428 (SFMP)

The Lockhart Flood Study was completed in 1999. In October 2010 and March 2012, record floods levels were documented with little or no warning. The review of the study will incorporate these new levels, and the development of the flood risk management strategy and plan will determine the extent of possible mitigation measures that will allow plans and budgets to be developed.

The Rock Floodplain Risk Management Study and Plan
Funding: $85,714 (SFMP)

The Rock Floodplain Management Study and Plan was completed in April 2010. In October 2010, record flood levels were documented with little or no warning. The Rock has recently been severely affected again during the recent March 2012 event. The review of the study and plan will incorporate these new levels and revisit mitigation measures aimed at reducing risks due to flooding.

Maitland City Council

Floodplain risk management study and plan
Funding: $140,000 (FRMGS)

This project involves the continuation of the floodplain risk management study and plan.

Manly Council

Preparation of Manly local government area (LGA) flood study
Funding: $103,332 (FRMGS)

Manly Council will prepare a flood study for Manly LGA which will cover an approximate area of 10.6 square kilometres, including 16 subcatchments. Manly LGA is a highly urbanised coastal area with potential risk from fluvial, oceanic, and overland flows, including oceanic inundation.
The project will comprise a flood study to enable the council to identify and map flood risk in accordance with the Floodplain Development Manual (2005), Flood Prone Land Policy, Sea Level Rise Policy Statement, and climate change predictions.  This will fulfill the council’s obligations to identify and manage floodprone land to reduce risk to property and life. This study is being undertaken to further develop preliminary 'coarse resolution' mapping previously prepared and published in March 2008, and identify catchment flooding and coastal inundation risks. This project will provide more robust data and detailed mapping to enable the preparation of subsequent flood risk management strategies and plans, and also be used to inform strategic planning policy in the Manly LEP and DCP.

Marrickville Council

Hawthorne Canal flood study
Funding: $66,667 (SFMP)

Hawthorne Canal drains the catchments of Leichhardt, Ashfield and Marrickville councils. Leichhardt Council has recently completed detailed flood studies for its entire local government area. Marrickville and Ashfield councils strongly acknowledge the need to map floodprone properties within the Hawthorne Canal catchment and to introduce planning controls to protect people and property from future flood damage. As both council areas are undergoing redevelopment, there is a need for flood maps to establish minimum floor levels and the prohibition of structures in floodways.

Sydney Water is the owner of the trunk drainage system in the catchment and will undertake a flood study of its trunk main and Hawthorne Canal, as part of its asset management program. Marrickville and Ashfield councils will use this core flood model and extend it to a catchment overland flood study, which will be used for planning controls and will include community consultation.

Review of Cooks River floodplain risk management plan
Funding: $32,000 (FRMGS)

Marrickville Council, in conjunction with Canterbury Council, conducted a mainstream flood study of the Cooks River in 1994 and developed a subsequent Floodplain Management Plan in 1997. The aim of this project is to revise the existing plan, in light of the recently completed Cooks River Flood Study prepared by Sydney Water (PB/MWH 2009), which used more accurate 2D modelling and airborne laser scanning data. The 1994 flood study will also be updated to include NSW Planning sea level rise scenarios under climate change. The outcomes of the review will inform council’s planning instruments (LEP, DCP and s. 149 certificates) so they will be based on the best available flood hazard information.

Mid-Western Regional Council

Rylstone and Kandos floodplain risk management study and plan
Funding: $36,667 (FRMGS)

The council is currently investigating local flooding at Rylstone and Kandos to prepare a floodplain risk management study and plan (FRMS&P).  This study and plan will complement the current flood study being undertaken in both towns, which will identify overland flow behaviour including the extent, depth and velocity of floodwaters for the full range of flood events, up to and including the probable maximum flood level, in accordance with the Floodplain Development Manual.  Through the FRMS&P, the council will consider the number of flood affected properties and the degree of risk, and identify potential measures to mitigate flooding and reduce risk to life and property. The study will provide a plan which will allow the council to use and manage floodprone areas to reduce the impacts of flooding, flood liability and flood losses on both public and private lands.

Moree Plains Shire Council

Pallamallawa easement acquisition
Funding: $48,000 (SFMP)

The Pallamallawa Floodplain Risk Management Study has been completed, as have the design details for the levee bank upgrade. The next stage is to acquire the necessary easements over the levee bank to ensure that the upgrade can proceed.

House raising study in Moree and environs area
Funding: $97,873 (FRMGS)

This house raising study, which involves surveying floor and land levels, will underpin a house raising scheme for houses affected by flood waters in a 1% annual exceedence probability event within the Moree and environs area. This study will determine a priority ranking and accurately quantify the value of a house raising scheme. The project area known as 'Moree and environs' comprises the township of Moree, and the outlying rural residential areas of Bendygleet to the west, Gwydirfield to the east, and Yarraman to the north.

Moree Shire village floodplain risk management study to plan stage
Funding: $12,000 (SFMP)

The three villages of Moree Plains Shire have recently all completed their floodplain risk management studies. The next stage is to review the flood studies with the objective being to complete the  floodplain risk management plans for each village.

Pallamallawa Floodplain Risk Management Flood Study review
Funding: $12,000 (SFMP)

The Pallamallawa Floodplain Risk Management Study has been completed as have the design details for the levee bank upgrade. The next stage is to review the flood study modelling against the two most recent events which were the most significant events experienced on the Gwydir in 30 years.

Installation of historic and 1-in-100 flood markers for Moree and environs
Funding: $31,200 (FRMGS)

This project will place flood markers on power poles, or similar, in the residential area of Moree and its environs to raise community awareness of historical flood height and possible future flood heights in the area. The project area known as 'Moree and environs' comprises the township of Moree and the outlying rural residential areas of Bendygleet to the west, Gwydirfield to the east and Yarraman to the north.

Mosman Municipal Council

Mosman flood study
Funding: $120,000 (SFMP)

This study will determine flood behaviour in the Mosman local government area, under existing catchment conditions, for a range of flood events. A preliminary study undertaken with currently available information has revealed that stormwater behaviour is more complex than expected with cross-catchment flows common and flow paths varying with water depth and rainfall intensity. Further data is required to ensure adequate model set up and calibration to describe the true catchment behaviour. Data recently collected for the Mosman Stormwater Asset Management Plan will be used to update the model and to determine the flood behaviour of the study area for a range of flood events and climate change scenarios. A sensitivity analysis will be conducted to assess the relative influence on model results of key parameters including those simulating rainfall (spatial and temporal), rainfall losses, friction, energy losses, and blocked culverts and other structures. Community consultation will be undertaken.

Murrumbidgee Shire Council

Darlington Point levee: environmental assessment and Stage 1 reconstruction
Funding: $2,599,555 (SFMP)

The levee bank at Darlington Point has a current imminent failure level (IFL) of 7.2 metres, which means the levee can hold the water up to that height. In the event of flooding, once the prediction goes over that level the town undergoes evacuation orders. The past studies have shown that it has cost the government over $1 million each time the town is evacuated, including the cost of accommodation and other associated costs. On completion of this project, the IFL of the levee will be raised to a level that will prevent evacuations should any more floods occur. This raised level will reduce flood disaster management costs.

Muswellbrook Shire Council

Hunter River flood study
Funding: $130,000 (SFMP)

This study will define the flood behaviour on the Hunter River floodplain extending from the upstream to downstream boundary of the council’s local government area.  This flood study will form the basis for the subsequent floodplain risk management study and plan, where detailed assessment of flood mitigation options and floodplain management measures will be undertaken.

Narrabri Shire Council

Wee Waa floodplain risk management study and plan
Funding: $10,000 (FRMGS)

Because of its considerable length and the variable flood slopes, there is a risk that the levee may be overtopped even if it has a gradient along its length equal to that observed in a previous major flood. This study will therefore resolve the design levels for the levee, the overtopping risk and the potential impacts inside the levee.

Narrabri flood study review
Funding: $70,000 (FRMGS)

This project will help the council to understand and refine existing flood behaviour and establish and reinforce the technical basis for floodplain management activities. The council will also review and update the MIKE 11 hydraulic model of the Namoi River/Narrabri Creek system, and verify the flood behaviour through the town of Narrabri.

Narrandera Shire Council

Narrandera levee protection upgrade project: investigation and design
Funding: $77,143 (SFMP)

Key recommendations from the Narrandera Floodplain Risk Management Plan (2008) identify that several levees around the township are in need of construction or upgrading to provide a 100 year average recurrence interval level of protection. These levees include the Main Canal Southern Embankment upgrade, Aerodrome levee upgrade and the construction of new levees around the Water Supply Pumping Station and Nallabooma Estate. This project involves the investigation and detailed design of these new and upgraded levee systems, sufficient to progress to the next stage of construction. These measures will provide a higher level of protection to the town than presently exists and mitigate the risks due to flooding, which has recently been experienced at Narrandera during the March 2012 event.

Narromine Shire Council

Narromine levee investigations: Stage 2
Funding: $437,143 (SFMP)

Narromine Shire Council intends to extend the existing levee further to provide reasonable flood protection for the major part of the town of Narromine and its residents. The council is engaging consultants to undertake studies associated with the Narromine Town levee investigation and concept design.

Newcastle City Council

Wallsend Floodplain Risk Management Plan:  Implementation Phase 2
Funding: $156,600 (SFMP)

Through this project, detailed hydraulic modelling and building structural information will be applied to enable a detailed cost-benefit analysis of each of the options recommended in the Wallsend Floodplain Risk Management Plan, to be determined. The order and priority of works implementation will also be determined.

Newcastle City-wide Floodplain Risk Management Study and Plan: strategic land use issues
Funding: $188,000 (SFMP)

The draft Newcastle City-wide Floodplain Risk Management Study and Plan has identified a high priority need to develop a strategic position for low-lying suburbs affected by predicted future sea level rise. Existing and future development in parts of the low-lying Newcastle suburbs of Wickham, Maryville, Carrington and Stockton will be compromised if the sea level rises as currently predicted. The proposed strategic assessment will consider engineering, social, economic and planning issues,  to establish appropriate management options for these threatened areas. It is expected that there will need to be considerable community engagement and input.

Newcastle City-wide Floodplain Risk Management Study and Plan
Funding: $20,000 (FRMGS)

The draft Newcastle City-wide Floodplain Risk Management Study and Plan has been developed to direct and coordinate the future management of floodprone lands across the City of Newcastle. It also aims to educate the community about flood risks across Newcastle so they can make more appropriate and informed decisions regarding their individual exposure and responses to flood risks. The flood plan sets out short-term and long-term actions and initiatives to be undertaken by agencies and the community, to adequately address the risks posed by flooding.

Newcastle City-wide Floodplain Floodplain Risk Management Plan: flood warning system
Funding: $30,000 (SFMP)

The draft Newcastle City-wide Floodplain Risk Management Study and Plan (FRMS&P) identifies the action to 'Develop and operate a complete flash flood warning system for Newcastle' as one of the cornerstones of the FRMS&P. The FRMS&P for the Wallsend Commercial Centre also identified a flood warning system as a critical component. Flash flooding in the Newcastle urban area occurs very quickly, with considerable risk to life. A state-of-the-art complete flood warning system is proposed to attempt to provide early warning to residents to minimise the risks in extreme flood events. The flood warning system needs to be a cooperative venture between CofN, BOM and SES and be integrated with the Community Education Program and other FRMS&P actions. To commence this project, funding has been awarded to undertake a feasibility study.

Palerang Council

Captains Flat flood study
Funding: $64,000 (FRMGS)

Captains Flat has a history of mainstream flooding of the Molonglo River where it passes through the town.  The flooding occurs just downstream of an 820 ML dam that supplies the town with its water supply, and for larger flood events inundates a number of residences and businesses when the river breaks its banks.

Through this study, the extent of this flooding will be defined, appropriate development controls will be determined and a floodplain risk management plan will be developed. The effects of the dam structure and its operation will be considered.

Bungendore flood risk management study and plan
Funding: $31,570 (FRMGS)

Bungendore has a history of mainstream flooding of the Turallo Creek and Halfway Creek which pass through the town. There is a need to determine appropriate development controls, and implement a floodplain risk management plan,  to lessen the impact on properties that are inundated during flooding events.

Parkes Shire Council

Flood and risk management study of the Trundle township catchment
Funding: $90,000 (FRMGS)

A flood study and subsequent floodplain risk management study will be undertaken for the Trundle township area, to determine measures that may be taken to reduce the impact of flood water on the community. This will include the protection of residential and commercial properties from inundation, identifying 'dry areas' for use during flood events and preparing plans of management for local infrastructure including the hospital, school and community buildings to allow for continuity of service during floods.

Penrith City Council

Nepean River flood study
Funding: $2,000 (FRMGS)

The overall aim of the study is to investigate the design flood behaviour of the Hawkesbury-Nepean River and its floodplain, between the Glenbrook Creek confluence upstream of M4 Bridge and downstream to Yarramundi Bridge. The study will define the design flood levels, flows, and velocities for a range of design flood events to help the council to define the flood planning level. The study will also produce information on provisional flood hazard categories.

South Creek and its tributaries (including Ropes Creek) flood study
Funding: $3,333 (FRMGS)

The overall objective of the study is to review and update mainstream flood behaviour for South Creek and its tributaries, including Ropes Creek. The study area covers South Creek Catchment between Bringelly Road to the south and Blacktown/Richmond Road to the north. The study will produce information on provisional hydraulic and hazard categories, flood levels, flood depths, velocities and flows for a full range of flood events under current catchment and floodplain conditions. The study will provide the State Emergency Services with the flood intelligence data at key points of interest.

Detailed overland flow flood studies: Penrith central business district (CBD) and St Marys (Byrnes Creek)
Funding: $4,667 (FRMGS)

There are two separate study areas nominated for a detailed flood study in this project. Study area 1 lies in the Byrnes Creek Catchment near St Marys. Study areas 2 and 3 comprise the suburb of Penrith, with Penrith CBD along the northern boundary of the area, and residential areas to the south and east.

The primary objective of the flood study is to define the flood behaviour for the range of flood events in the study areas. All potential flooding mechanisms will be included in the analysis of flood behaviour, including overland flow and creek flooding. The study will produce information on flood flows, velocities, flood levels and extents for a range of flood events. Secondary objectives of the study are to enhance the council’s drainage infrastructure database, identify existing drainage capacity deficiencies and provide preliminary advice on various options for upgrading the drainage system.

Pittwater Council

Nareen Creek foodplain risk management study and plan finalisation
Funding: $10,000 (FRMGS)

It is predicted the five-year flood event in this area has a total of 37 properties with overfloor flooding, and the probable maximum flood level has 307 properties affected. This addendum to the Nareen Creek floodplain risk management study and plan will involve assessing the risk to life within the catchment through assessing the population at risk, structural integrity of dwellings, inundation duration, potential evacuation routes and evacuation capability. It will also propose management options to deal with this risk, such as development controls, specific property modification measures and recovery planning. It is also proposed to investigate the acceptable criteria for management as detailed in the National Emergency Risk Assessment Guidelines (2010).

Detailed design for North Arm (Newport) flood mitigation works
Funding: $50,000 (FRMGS)

The Newport Beach Floodplain North - Flood Management Options Feasibility Report (2010) demonstrated that North Arm flood improvement works could be cost-effective and provide some degree of flood mitigation. The works include:

  • regrading and splitting overland flows
  • upgrading pit inlet capacities
  • channel regrading and reshaping
  • defining flow paths between units and removing flow obstructions.

It is proposed to inform the community of the outcomes of the feasibility study and undertake detailed design of the minor flowpath improvement works.  Lastly, Pittwater Council proposes to engage a qualified consultant to complete the detailed design drawings for construction.

Careel Creek (Avalon) flood study update
Funding: $48,574 (SFMP)

The Careel Creek Drainage Catchment Flood Study was completed in 1999, while the Floodplain Management Study was completed in 2000. Both were adopted by the council in 2000. The Careel Creek Floodplain Management Plan was adopted by the council in 2002. About 400 properties in the Careel Creek Catchment at Avalon are flood-affected. In a 1% annual exceedence probability flood event, about 14 houses and about 40 businesses would be flooded to about floor level.

The current study will update the 1999 Careel Creek Drainage Catchment Flood Study, which contains hydrology and hydraulic modelling that is now more than 10 years old, to reflect current catchment conditions, incorporate a detailed climate change assessment and utilise the most up-to-date topographical data and floodplain modelling techniques.

Northern Beaches flood warning and flood information network
Funding: $61,399 (SFMP)

Information currently provided by the Narrabeen and Manly LagoonWatch websites from rainfall gauges, water level recorders and alarms is essential for providing real-time information for flood management of the four coastal lagoons on the Northern Beaches. Pittwater Council, in partnership with Warringah and Manly councils, is working to provide a regional and more strategic approach to the management of rainfall and water level gauges. The provision of this information to councils and the public is also essential in managing lagoon and flash flooding.  Funding under this program is limited to three years.

Port Macquarie-Hastings Council

Dunbogan flood access construction Stage 1 (a & b)
Funding: $1,148,000 (SFMP)

The Camden Haven Floodplain Management Plan (2004) identified the need for improved evacuation to Dunbogan. This project is to construct Stage 1 (a & b) of the evacuation improvements. The project will involve raising and resealing the existing road equal to the 1:100 year flood level.

Richmond River County Council

Water quality monitoring: Richmond River (Rocky Mouth Creek and Tuckombil)
Funding: $68,000 (SFMP)

The Rocky Mouth Creek/Tuckombil/Tuckaen floodplain systems remain important for state government, local government and the local community. All systems have multi-stakeholder groups with challenging and often conflicting views on flood mitigation infrastructure management. This project utilises data-loggers at floodgates at strategic sights within the project area, which can be remotely accessed for real-time data, to allow for integrated management of these complex systems. The council can use this data to regularly respond to stakeholder submissions and provide information to gain the best operational outcome.

Review of the Richmond Valley flood warning and evacuation planning system
Funding: $80,000 (SFMP)

In the Richmond River Valley, recurrent flooding is a major issue for the community and local authorities. The valley has had major flooding in 1954 (1:70 average recurrance interval (ARI)); 1974 (1:70 ARI); 1989 (1:20 ARI); 2005, 2008 and 2009 (1:10 ARI). Currently, a number of local and state authorities are engaged with flood warning and evacuation planning.  This project will review all current flood warning and evacuation systems and the details of ownership, datums, location and flood education.

Final of Ballina flood risk management study and plan including Newrybar
Funding: $80,000 (SFMP)

This is the final stage in the development of the Ballina floodplain risk management study and plan. Remaining works include refining some modelling, placing the documents on public display, producing an information brochure and finally, reviewing public submissions and incorporating them, where appropriate, into a final plan.

Richmond Valley flood emergency management project
Funding: $60,000 (FRMGS)

The council has recently completed a valley-wide flood model that provides information on 1-in-100 year flood levels across the whole floodplain. This project will lead to the development of a flood emergency management plan using the information that has become available from the floodplain modelling.

River gauges installation: Evans River 
Funding: $20,000 (SFMP)

Council has recently completed a valley-wide flood model that provides 1 in 100 flood levels across the whole floodplain. However, this did not include the Evans River which is an overflow of the Richmond River . Evans River is impacted by both tidal movements and water overflowing from the Richmond River system. The plan is to install two automatic river gauging stations which will record flood and river levels on an hourly basis. These can be compared against the Richmond River levels. These gauging stations are a fundamental step towards the extension of the Richmond River flood model. Until there is reliable river height-flood flow information it will be impossible to extend the flood model to Evans Head and surrounding areas. This is recommended as a result of council's coastline hazard study.

Rockdale City Council

Arncliffe Park detention basin feasibility review and detailed design
Funding: $80,000 (FRMGS)

Arncliffe Park is a local heritage park in Arncliffe. A floodplain risk management plan recommended that a detention basin be constructed at Arncliffe Park to mitigate flooding, and a feasibility study made recommendations for the preferred option for integrating the detention basin and sports field. The feasibility study and detailed design will reassess options and document the preferred option for detention, using recently reviewed flow data from the Bonnie Doon Pipe and Overland 2D Flood Study.

Muddy Creek, Scarborough Ponds, Sans Souci climate change flood management study review
Funding: $60,000 (SFMP)

Flooding in the catchments has been studied in 2000 and 2005 resulting in the approval of two flood risk management plans. Since then, climate change benchmarks have been subject to ongoing review. The project will study the impacts resulting from climate change to achieve revised flood mapping and a revised flood risk management plan considering planning, response and structural mitigation options.

Ryde City Council

Investigation and design of detention basin at Waterloo Park, Marsfield
Funding: $50,000 (FRMGS)

The City of Ryde completed the Macquarie Park Floodplain Risk Management Study and Plan in December 2010. The study was adopted by the council on 1 February 2011. The study recommended a detention basin be constructed at Waterloo Park, Marsfield. The detention basin can be easily formed by constructing a 1-m high and 120-m long earth bund. The advantage of this site is that it is just upstream of the existing flooding problem areas. There is also the potential for directing outflow from the basin away from the flooding areas.

Buffalo and Kittys Creek flood study and floodplain risk management study and plan
Funding: $170,000 (SFMP)

The City of Ryde experienced several large storm events in 1984, 1986, 1988 (twice), 1989 (twice) and 1990 which caused widespread flooding. Since that period, rainfall events in May 1998 and April 2003 have caused significant problems. Most of the stormwater systems in the study area consist of underground pipes but some natural watercourses remain. The underground stormwater systems in the study area are in the latter half of their service life and generally do not have adequate capacity to cope with large storm events.

Through the flood study and floodplain risk management study and plan, the nature and extent of flooding in the two catchments will be determined. These documents will outline options for addressing the problems and recommend preferred options based on benefit-cost ratio and feasibility. The study will focus on the Buffalo Creek and Kitty's Creek catchments.

Parramatta River/Ryde subcatchments flood study and floodplain risk management study and plan
Funding: $154,000 (SFMP)

The Archer Creek, Denistone, Charity Creek, River and Gladesville catchments contain five major stormwater drainage systems which flow into Parramatta River. The stormwater systems generally originate in the residential areas south of Blaxland Road and Lane Cove Road, flowing from north to south into the Parramatta River.  Most of the stormwater systems in the study area consist of underground pipes but some natural watercourses remain. The underground stormwater systems in the study area are in the latter half of their service life and generally do not have adequate capacity to cope with large storm events.

Through this study, the existing flooding regime in the five catchments will be investigated, with particular focus on the Parramatta River/ Ryde subcatchments. A flood risk management strategy and plan will also be developed in accordance with the NSW Government’s Floodplain Development Manual.

Shellharbour City Council

Elliot Lake/Little Lake floodplain risk management study and plan
Funding: $100,000 (SFMP)

The Elliot Lake/Little Lake Flood Study was the first stage of the management process for Elliot Lake/Little Lake Catchment, and defined flood behaviour under April 2001 catchment conditions, as well as under two development stages of fully developed/final catchment conditions. A detailed investigation of wave propagation to the near-shore entrance area was also undertaken to investigate the importance of wave propagation and wave set-up at the ocean entrance of the lake. This involved modelling four flood scenarios, i.e. ocean water level peak coincides with the flood peak, ocean water level peak occurs earlier than the flood peak, ocean water level peak occurs later than the flood peak and constant ocean water level.

The information gathered in this flood study will be processed and analysed in an assessment of flood risk to develop a list of potential flood risk management options in a floodplain risk management study and plan.

Horsley Creek floodplain risk management study and plan
Funding: $86,000 (SFMP)

Horsley Creek drains an area of approximately nine square kilometres of mostly urbanised land, discharging into the south-western corner of Lake Illawarra. Flooding in Horsley Creek and its tributaries is adversely affected at many locations by bridges, culverts and intrusions of development onto floodplains. Flooding in the lower reaches of Horsley Creek is also affected by the level of flooding in Lake Illawarra and sand build-up in the outfall reach into Lake Illawarra. The Horsley Creek Catchment is almost entirely cleared of forest (~90%). Only small areas of remnant forest remain on steeper areas near the quarries and low-lying areas near the lake and airport. The northern half of the catchment is largely covered by residential and light industrial development. The southern half of the catchment contains two large hard rock quarry operations which have also resulted in significant catchment disturbance. The catchment also has a complex drainage pattern significantly impacted on by manufactured drainage systems associated with transport corridors.

Through this project, a floodplain risk management study and plan will be developed to deal with these issues.

Macquarie Rivulet flood study
Funding: $166,667 (SFMP)

Macquarie Rivulet (the major stream draining the catchment) and its tributaries drain a catchment area of approximately 110 square kilometres into Lake Illawarra. The floodplain within the catchment is located primarily adjacent to the main watercourses with a broader floodplain in the low-lying areas of the catchment.  The catchment is very diverse, comprising escarpment, bushland, rural land, relatively new and old low/medium density residential areas and industrial development. The study area contains major transport infrastructure including the major road and rail links to the south coast, a major road link to the southern highlands and a regional airport. Some of these links are known to be flood affected while others, such as the airport, may be affected in an extreme event. North-east of the Princes Highway and railway, the catchment comprises a mix of light industrial and low density housing. South-east of the Princes Highway and railway is the area containing the confluence of the south-eastern tributaries of the catchment with Macquarie Rivulet.

Greenwell Point flood risk management options feasibility study
Funding: $40,000 (SFMP)

The Lower Shoalhaven River Floodplain Risk Management Study and Plan (2008) and subsequent climate change risk assessment (2011) show that the village of Greenwell Point is at significant flood risk. The village would experience access and evacuation difficulties in as little as the 10% annual exceedence probability (AEP) flood design event and about 340 buildings would experience flood damages, evaluated at $15 million, in a 1% AEP flood event.

The climate change risk assessment shows that sea level rise would have significant effects on more frequent flood events, with the overall damages to residential developments under a 0.9 m sea level rise scenario expected to be three times greater than under present conditions.

The plan recommends a number of measures be investigated such as raising of Greenwell Point Road and construction of a levee. The purpose of this project is to undertake a feasibility study of these measures.

Singleton Council

Wollombi Brook flood study
Funding: $30,000 (FRMGS)

The Wollombi Brook Catchment extends from the Yango State Forest to Walkworth and is approximately 800 square kilometres. The increasing popularity of Wollombi Brook has resulted in a steady rise in the number of development applications for residential dwellings, weekenders and farm buildings. The catchment is fed by a number of tributaries including Cody Creek, Drews Creek, Wambo Creek and other numerous creeks.

As major flooding has occurred in the valley on a number of occasions, and no flood studies have been undertaken of Wollombi Brook, it is proposed to model the downstream section of the Wollombi Brook from Paynes Crossing to Warkworth, where several small villages and settlements including Broke, Fordwich and Bulga, are affected by mainstream flooding.

The study deals with damage to buildings and assets, and  emergency management, as well as long-term town planning issues that the council intends to address.

Tumut Shire Council

Adelong flood study: Stage 2
Funding: $20,400 (SFMP)

The township of Adelong, in the south-west slopes of NSW, experiences regular flooding from the Adelong Creek. An Adelong Flood Study was prepared 25 years ago following a major flood in 1984. Major flooding in December 2010 resulted in at least half a metre of water in the main street, causing millions of dollars of damage to public infrastructure, businesses and residential properties. Indications are that the December 2010 flood was equal to, if not greater than, a 1:100 year flood.

This project involves continuing with the preparation of a new Adelong Flood Study. The information will enable State Emergency Services to plan for and respond to floods more effectively and will help Tumut Shire Council improve its management of floodprone land.

The towns are located on the Murray River and are protected from flooding by a series of levees to various heights and standards of construction to 1:15 year protection.

All towns during a major flood are isolated from main service areas such as Swan Hill and Deniliquin, where supermarkets, medical, schools and fuel supplies are located. The project will recommend personal and property protection as well as protect the social structure of the towns during periods of isolation. Essential services such as water supply and sewerage, roads and electricity will be protected.

Warringah Council

Manly Lagoon flood study
Funding: $22,128 (SFMP)

The council is updating a 1992 flood study for the Manly Lagoon Catchment to allow for the assessment of future flood risk from factors such as climate change and sea level rise. The project aims to identify the floodprone areas within the entire Manly Lagoon catchment, and plan management options to mitigate the flood risks in these areas. The Manly Lagoon Catchment Coordinating Committee (MLCCC) will act as the key stakeholder reference group for the project. There will be significant public consultation undertaken in addition to liaison with the MLCCC. The flood study will investigate flooding from fluvial, tidal and overland flows. An assessment of the impacts of sea level rise and increase in rainfall intensity will also be undertaken. This is a joint project between Warringah and Manly councils, with Warringah Council responsible for day-to-day project management.

Narrabeen Lagoon Flood Study
Funding: $23,350 (FRMGS)

This project will use 2D modelling to assess the full impacts of flooding throughout the main creeks within the entire catchment. Narrabeen Lagoon is an Intermittently Closed/Open Lake or Lagoon (ICOLL). The flood study will investigate flooding from fluvial and tidal sources and assess the impact of sea level rise and increased rainfall intensity. An assessment of the lagoon entrance will be undertaken to determine the sensitivity of the flood levels to the entrance conditions. This is a joint project between Warringah and Pittwater councils, with Warringah Council responsible for day-to-day project management.

Dee Why Lagoon South Catchment flood study
Funding: $88,000 (FRMGS)

Warringah Council will undertake a formal flood study for the Dee Why Lagoon South Catchment. The most recent flood investigations were undertaken in 2011. A 1D/2D XPSWMM model was developed and has suggested that there is significant hazard and risk to the residents within the catchment. However a formal flood study in accordance with the Floodplain Development Manual (2005) has never been undertaken for the whole catchment. Suitably qualified consultants will undertake a peer review of the existing 1D/2D XPSWMM model and carry out further modelling to produce a flood study document so the community can clearly understand the flood risks within the Dee Why Lagoon South Catchment. The effects of climate change, such as rainfall intensity and sea level rise, will be an integral part of the investigations.

As many properties were built on the creek bank, a detailed flood study is required as a first stage in the floodplain risk management process. The flood study is expected to be complete in 2012-13 and will be overseen by the council’s Floodplain Management Committee.

Stage 1: Wingecarribee River flood study
Funding: $64,000 (SFMP)

Wingecarribee River is a major river in the Shire. About 70% of the catchment of the river is situated downstream of the Wingecarribee Water Supply Dam. The townships of Burradoo, Moss Vale and Berrima are on the banks of the river. The flood study will form the first stage of the floodplain risk management process. An aerial survey is complete and the flood study will commence in 2011-12.

Wollongong City Council

Review of Hewitts Creek Flood Study
Funding: $86,667 (SFMP)

This project entails a review of the Hewitts Creek Floodplain Risk Management Study and Plan. It will be eight years since it was completed, and since then improvements in technology such as 2D modelling software, airborne laser scanning data capture and the requirements to include climate change in flood studies could impact on the outcomes of the existing study and plan.

The existing study and plan will be reviewed on the basis of the new requirements and updated data will be incorporated to ensure the current plan recommendations and land use planning data are still relevant or need to be amended.

Collins Creek flood risk management study and plan
Funding: $88,753 (FRMGS)

Through this project, a floodplain risk management study and plan will be prepared in accordance with the NSW Floodplain Development Manual and solutions to mitigate flooding issues in the combined catchments of Whartons, Collins, Farrahars Creeks, Bellambi Gully and Bellambi Lake will be investigated.

Fairy & Cabbage Tree creeks: Design of 15 debris control structures
Funding: $210,000 (SFMP)

Detailed design for priority works will be undertaken as recommended in the Fairy and Cabbage Tree creeks FRMS&P to minimise blockage of culverts and prevent damage to property from significant flood events. This project will develop design documentation for the identified high priority debris control sites.

Hewitts Creek Flood Mitigation Scheme: Tramway Creek design for rail culvert upgrade
Funding: $40,000 (FRMGS)

The council’s flood risk management plan identified an opportunity to reduce the incidence of flooding along Tramway Creek immediately upstream of the Illawarra railway line. This is to be achieved by upgrading the existing culverts beneath the railway line to significantly increase the capacity of the current system. The aim of the project, which is currently in progress, is to investigate this option in detail and prepare documents suitable for construction purposes.

Mullet and Brooks creeks: Emerson Road culverts
Funding: $70,000 (FRMGS)

The council will undertake priority detailed designs for future works as recommended in the Mullet and Brooks Creeks Flood Risk Management Study and Plan. This includes works to reduce the blockage of Emerson Road culvert and damage to 35 flood affected properties upstream of the works.

Brandy and  Water Creek bank design
Funding: $73,333 (SFMP)

The council will undertake further investigation and design of creek bank modification along Brandy and Water Creek, opposite Darragh Drive, Figtree, as recommended in the Allans Creek Flood Risk Management Study and Plan.

Review of Towradgi Creek Flood Risk Management Study and Plan
Funding: $86,667 (SFMP)

This project entails a review of the Towradgi Creek Flood Risk Management Study and Plan. It will be nine years since it was completed and since then improvements in technology such as 2D modelling software, airborne laser scanning data capture and the requirements to include climate change in flood studies could impact on the outcomes of the existing study and plan.

The existing study and plan will be reviewed on the basis of the new requirements and updated data will be incorporated to ensure the current plan recommendations and land use planning data are still relevant or need to be amended.

Upper Byarong Creek: Detailed design of debris control structure
Funding: $40,000 (SFMP)

The detailed design of debris control structure upstream of Koloona Avenue Bridge will be undertaken, as recommended in the Allans Creek Floodplain Risk Management Strategy and Plan.

Woollahra Municipal Council

Cecil Lane overland flow path: Stage 2
Funding: $133,333 (SFMP)

Cecil Lane in Paddington is at the bottom end of Rushcutters Bay Catchment and receives overland flow from a large area of Paddington, causing regular flooding. Council records show the area experiences floods that cause major damage every five years, and frequent minor flooding. The area is floodprone as there is currently no overland flowpath from Cecil Lane. The downstream Trumper Park is at a higher level and therefore blocks all overland flow. The only way the area can currently drain is through an undersized drainage system. It is impractical to upgrade this system as it drains to major Sydney Water-owned infrastructure downstream that is also undersized.

The project aims to provide an effective overland flowpath by lowering Trumper Oval. The project was ranked as the highest priority in the Rushcutters Bay Flood Risk Management Study and Plan. When complete, this work will greatly reduce the frequency and severity of flooding in this high density, largely residential area.

Wyong Shire Council

Wyong River Catchments Flood Study (Stage 1)
Funding: $151,000 (SFMP)

This project involves a flood study review. Previous studies of this catchment were not done on a full catchment scale; they were carried out as Upper and Lower Wyong River flood studies, and carried out over 20 years ago using the CELLS model in 1988 (Upper Wyong River) and 1991 (Lower Wyong River). This study will enable a 2D hydraulic model to be developed for the full catchment with associated flood extents, hazards and preliminary flood planning areas mapped.

Killarney Vale overland flood study (Stage 1)
Funding: $100,000 (SFMP)

This project involves a flood study of 5.1 square kilometres of a floodprone urban area. There have not been any previous flood studies, although a stormwater drainage study had been carried out for part of the study area (Saltwater Creek Stormwater Drainage Study 1981).

Tumbi Creek floodplain risk management: Stage 2
Funding: $10,000 (FRMGS)

This project involves a public exhibition of the recommended flood risk management plan and preparing a final report for adoption by the council.

Ourimbah Creek Catchments Flood Study (Stage 1)
Funding: $134,000 (SFMP)

This project is a flood study review. Previous flood studies were carried out in 1994 (Bangalow Creek and Cutrock Creek), 1995 (Lower Ourimbah Creek) and 1997 (Upper Ourimbah Creek).

Tuggerah Lakes floodplain risk management plan (Stage 2)
Funding: $10,000 (FRMGS)

The public exhibition process for the recommended flood risk management study is complete. Several issues have been raised about floor level controls and sea level rise planning that will require amendments to the study. The flood risk management plan will then be exhibited before a final report is prepared for adoption by the council.

Young Shire Council

Continuation of Young flood study
Funding: $108,000 (FRMGS)

During the severe weather events of November and December 2010, Burrangong Creek and its tributaries all experienced high flows, causing damage to infrastructure such as dams and weirs located in-stream. Additionally, overland flows from higher in the catchment caused flooding in the Young central business district. The aim of this project is to complete a flood study to enable Young to implement strategies to minimise the impact of flooding and overland flows.
