Note: for ongoing projects, the project summary may reflect the whole project scope
The objective of this study is to define the flood behaviour under historic and existing conditions for the Murray River from the Hume Dam embankment to the western most boundary of Council’s LGA. The study will produce information on flood levels, velocities, flows, hydraulic categories and provisional hazard categories for the specified range of design flood events (up to and including the 1 in 500 year event) under existing catchment and floodplain conditions. The project will update/replace the existing studies carried out on the Murray River system since the early 1980s including the most recent studies that were associated with the construction of the Hume Freeway, Wodonga Rail Bypass and the Gateway Island Development. State Water on behalf of the MDBA will look at larger events as part of their investigations into the security of the Dartmouth and Hume Dams. The study area is approximately 70 square kilometres and has the Kiewa River as a major tributary. Once completed the findings of this study, combined with other flood studies, will support the preparation of a Flood Risk Management Plan for Albury City Council.
Updating of the 2004 Flood Study, including sensitivity analysis for impacts of Climate Change and extension of study area to cover new urban release areas. Completion of Stage 2 works, and extension of the study (Stage 3) to cover flooding hydraulics in several tributary and main creek growth areas not previously considered in detail.
Review of Haslams Creek Floodplain Risk Management Study and Plan will include a review of current studies, extend the TUFLOW model to the entire Haslams Creek Catchment and review the risk management options. The new study will reduce the number of flood affected properties and will provide more significant flood mitigation opportunities. It will also provide accurate flood maps which can be used for development control, insurance purposes and risk management purposes.
Recent significant rain events in September, December 2010 and February 2011 have seen large volumes of surface rain water collected and, coupled with the recent high water levels in the flooded Murrumbidgee River, the temporary pumping system on the corner of Moa and Turandurey Streets cannot discharge the water quickly enough. The river can remain in flood for up to six months of the year, which restricts the gravity discharge of stormwater from the township. Flooding of houses and property damage has occurred recently and in the past. Council currently deploys a temporary pumping system to pump stormwater over the flood levee bank to prevent flooding of the local streets. The manual and temporary nature of this solution is unsafe and problematic for the proper drainage of the township. The solution proposed provides an automatic electric pump which will be triggered by rising water in the stormwater drain.
The Flood Risk Management Study and Plan for sub catchments of the Mid Georges River involves: reviewing existing flood studies for Little Salt Pan Creek, Morris Gully, Picnic Point, Lucas Road, East Hills, Kelso Swamp and Milperra, which were completed and adopted between 2006 and 2011; undertaking consultation with flood affected property owners; developing options to mitigate against existing flooding; and reviewing LGA wide planning controls developed as part of the Salt Pan Creek Flood Risk Management Study and Plan, including changes to controls as a result of assessing susceptibility to climate change.
The Salt Pan Creek Flood Risk Management Study and Plan involves reviewing existing flood studies for Salt Pan Creek, Fairford Road, Padstow and Davies Road which were all completed in 2009; undertaking consultation with flood affected property owners; developing options to mitigate against existing flooding; and making changes to existing planning controls, including changes to controls as a result of assessing susceptibility to climate change.
This project is for the construction of a levee to protect properties around Carlingford Street Bathurst. The Carlingford Street levee will comprise an earth embankment and reinforced concrete levee to protect 11 residential properties with an approximate length of 600m.
This project is for the construction of a levee to protect properties in the village of Perthville. The Perthville levee will comprise an earth embankment and reinforced concrete levee, will increase the hydraulic capacity of the existing bridge and provide channel improvements to protect 18 residential properties with an approximate length of 1400m.
The project is to undertake a flood study of the Bega and Brogo rivers to update the 1979 flood inundation map of Bega. The previous flood map was developed following the 1971 flood and is considered out of date. Bega is experiencing pressure to expand and the revised flood maps will provide up to date information on which to base future planning decisions. The information will be used to develop a floodplain risk management plan and provide essential information to the combat agencies in the event of a flood.
The project sites of Newry Island and the Lower Bellingen and Kalang Flood Study are located between the towns of Bellingen and Urunga. The Lower Bellinger and Kalang Study will incorporate revised flood levels (calibration) and account for predicted sea level rise as a result of climate change. This stage of the project will investigate the hydraulics of the system as the previous stage had investigated the hydrology. The Newry Island Flood Study will be incorporated and will investigate hydrology and hydraulics. This will give much better information for development proposals.
NSW Government planning has identified the North West Growth Centre and the Western Sydney Employment Area as major new growth centres within the Sydney region. Substantial areas of these new centres are located within the Eastern Creek catchment together with existing urban areas planned for renewal and consolidation. Given the scale of the proposed new centres and development, a regional approach to floodplain management is proposed to deliver new development equitably and efficiently. The project will assess individual and cumulative impacts on flooding and identify any additional strategic planning controls and infrastructure measures to enable implementation of effective and sustainable floodplain risk management practices. Potential climate change flooding impacts will be assessed to inform development of effective policy to protect the future needs of the new communities.
This project is for the development of a floodplain risk management study and plan for the Glenbrook-Erskine Creek Catchment within the Blue Mountains Local Government Area. The management plan will be developed in 3 stages:
Stage 1: 2011-2012: Bullaburra to Hazelbrook (Bedford Creek Catchment)
Stage 2: 2012-2013: Faulconbridge to Sun Valley (Sassafras Gully Creek and Magdala Creek Catchment)
Stage 3: 2013-2014: Blaxland to Lapstone (Glenbrook Creek Catchment).
Properties at Hazelbrook have been built on the ridges as well as the "valleys". Council's registrar indicates Hazelbrook (Hazelbrook Creek and Woodford Creek Catchment) has the highest flood related issues within the Blue Mountains LGA. To date there has been no specific flood policy for this area. A significant number of flood damages were reported across Hazelbrook (Talbot Road, Log Bridge Place, Kingsway, Clear View Parade, Falcon Street and Oaklands Road) during the February 2010 storm. Council wish to undertake an overland flow path study to understand the extent and the hazards of the flooding in order to reduce the danger of flood damage to property and to personal safety, and ensure that future development is compatible with the flood risk. This is the first step of the floodplain risk management process. A floodplain risk management plan will follow once the overland flow path study is completed.
Preparation of a comprehensive Flood Study and Floodplain Risk Management Study and Plan for the Bombala township.
Burwood Council has completed the data collection and flood study phase of the floodplain risk management process. Council is also proposing to carry out a floodplain risk management study and plan on the Cooks River mainstream catchment within the Burwood LGA to include:
The Belongil Creek Flood Study has been completed and includes a climate change assessment. Council now needs to complete a Risk Management Study and proceed onto a management plan. The climate change assessment in the flood study has shown that Byron Bay is quite susceptible to climate change effects and therefore it is important that mitigation plans are prepared sooner, to allow a progressive implementation plan.
Council currently has a very old 1D cells model for the Brunswick River, this covers the towns of Mullumbimby and Brunswick Heads. During 2008, Council completed Airborne Laser Scanning (ALS) of the area, including the preparation of 250mm contours, Digital Elevation Modelling (DEM) and Digital Terrain Modelling (DTM). Council recently completed the Coastal Creeks Flood Study, a joint flood study between Byron Shire and Tweed Shire. This study incorporates the Marshalls Creek Floodplain, which is hydraulically connected to the Brunswick River. This study recommended that Council combine The Coastal Creeks Flood Model with a model which covers the Brunswick River, in order to properly understand the hydraulic link. The new 2D flood model for the Brunswick River will create more detailed flood levels, consider the effects of climate change on the towns and ensure appropriate development is completed in the towns in the future.
Completion of the ongoing Floodplain Risk Management Study review and adoption by Council.
Completion of the ongoing Floodplain Risk Management Study review and adoption by Council.
The primary objective of the study is to adequately define flood behaviour in the Narellan Creek catchment. The study will produce information on flood levels, velocities, flows, provisional hazard categories and a sensitivity analysis for a full range of potential flood events under existing catchment and floodplain conditions. The events of interest shall include the 20, 50, 100 and 500 year ARI events, together with the Probable Maximum Flood (PMF) and climate change scenarios.
The primary objective of the study and plan is to build on existing data and to adequately define flood behaviour in the Nepean River catchment within the Camden Local Government Area and to model the potential impacts of climate change. The study will produce information on flood levels, velocities, flows, hazard categories and a sensitivity analysis for a full range of potential flood events under existing catchment and floodplain conditions. The catchment area is within a high priority area as the continued urban expansion within the catchment is expected to increase.
The South West Growth Centre is one of the primary areas nominated for urban development in the Sydney Metropolitan Area and will contain approximately 110,000 new dwellings for approximately 300,000 new inhabitants. Of these new dwellings, 70,000 will be built in the South Creek Catchment in the Camden Local Government Area. The primary objective of the Floodplain Management Study and Plan is to provide a strategic framework for the development of the South Creek Catchment and the South West Growth Centre.
This project is a rolling project comprising the preparation of flood studies and floodplain risk management studies and plans in accordance with the procedure set out in the NSW Floodplain Development Manual. It is not possible to complete all the studies at one time and the program allows Council to be flexible and responsive in the approach taken. To date the flood studies for four catchment areas are nearing completion. Once signed off on these will proceed to Flood Risk Management Study and Plan preparation and consultation. Additional areas will also be programmed for the preparation of Flood Studies.
The Salt Pan Creek catchment consists of 26 square kilometres extending south from Liverpool Road and King Georges Road to the Georges River including the suburbs of Bankstown, Padstow, Riverwood and Lakemba. Portions of Peakhurst, Punchbowl, Mt Lewis, Greenacre and Lugarno are also included. The majority of the catchment is occupied by residential and commercial districts with some light industrial centres. Salt Pan Creek study was completed in 2010. The scope of this project includes:
The Lachlan Street levee construction project is a key project to complete the flood-proofing of Hillston NSW on the Lachlan River. The 2.3 km levee replaces and upgrades an earlier levee pushed up before a flood in 1990. It is a complex project as the levee traverses private properties and requires a pragmatic design approach to achieve a sensitive and effective outcome. An Assessment and Survey stage has been completed indicating deficiencies. An Investigation and Design Documentation stage is in progress. This final stage is the construction refurbishment and restoration project.
This project will continue the development of the Cessnock City Floodplain Risk Management Study and Plan and will include floor level survey, damages assessment, options assessment and extensive community consultation.
This project will continue the development of the Wallis, Swamp/Fishery Creek Floodplain Risk Management Study and Plan and will include floor level survey, damages assessment, options assessment and extensive community consultation.
This project will undertake a comprehensive Flood Study for the City of Botany Bay, in accordance with the NSW Government’s Floodplain Development Manual. Following completion of the Flood Study, Council will prepare a Floodplain Risk Management Study and Plan to identify risk management options for flood planning areas. The risk management options will be adopted within Council's comprehensive Development Control Plan to ensure future development appropriately addresses potential flooding impacts. This is an important part of understanding flooding within the Botany Bay LGA and ensuring that future development is not compromised by flooding nor results in future damage to property or persons as a result of development in these affected areas.
Council is proposing channel widening works to increase the capacity of Farmers Creek, Lithgow. In the past, this particularly narrow section of the creek has constricted the flow of fast-moving waters in flash flood events, resulting in the adjacent residential area, Hermitage Flat, being flooded and many houses being inundated well above floor level.
A Flood Study for the catchment has been completed and reported to Floodplain Risk Management Committee and Council. This application is to continue with the preparation of the Floodplain Risk Management Study and Plan. The proposed study is to investigate all available floodplain management options (structural and non structural), and to recommend flood mitigation solutions, and to adopt a practical Floodplain Risk Management Plan for the catchment addressing the community needs.
It is proposed to prepare a comprehensive Floodplain Risk Management Plan for the Blackwattle Bay catchment. The first stage is the preparation of a Flood Study. The proposed flood study will also include an assessment of risks from climate change and sea level rise impacts on the floodplains using Government agreed benchmarks. The flood study will provide flood levels, flood velocities and flood hazard categorisation for various flood events including 100 year and PMF events. It is proposed to establish a 2D flood model for the entire catchment. Council has already acquired ALS data as well as drainage inventory asset data that will be used for the flood modelling. Following the completion of a flood study a Floodplain Risk Management Study and Plan will be prepared.

Legislation requires that the adverse environmental impacts of past flood mitigation works be addressed. The purpose of this project is to actively manage an additional two existing flood drainage systems on the Clarence River to their natural hydrology. To date more than 70 similar Management Plans have been negotiated with landholders. Key results have included improved water quality and acid sulphate soil management, better fish passage and improved wetland habitats.
The Lower Clarence Flood Study Review was prepared in 2004 and produced a 2D flood model under current conditions. It has been used to prepare Floodplain Risk Management Plans for Grafton and the Lower Clarence, Iluka, Yamba and Ulmarra. The first stage of this project has undertaken a climate change risk sensitivity analysis of the current flood model to assess how flood levels may be affected. The next stage of the project is to modify the Lower Clarence Floodplain Management Plan to account for projected impacts of climate change on flood levels. The projected sea level rise over the next 100 years in particular will impact on design floods in the lower river areas.
Council has opened up over 70 floodgated watercourses. In some cases, this work has not adequately addressed the system behind the gate due to either unforeseen events or funding short falls. This project aims to improve the environmental management of back swamp areas and those sections of the drain behind the floodgate.
The village of Glenreagh, located on the Orara River, is subject to regular flooding. In recognition of this issue, Clarence Valley Council and the NSW State Government have provided funding for a Flood Study and Floodplain Risk Management Study and Plan. As the first stage of developing a floodplain risk management plan for the Orara River, this project will undertake a flood study, which will be linked in to a related study being undertaken by Coffs Harbour City Council for the section of the Orara River within that LGA. The flood study will provide background information for the preparation of a Floodplain Risk Management Study and Plan in future years.
Review of all recommended actions from all adopted flood plain risk management plans, but principally the Grafton and Lower Clarence FPRMP to document actions completed to date and to prioritise implementation of as yet uncompleted actions. Review all actions in order to identify and address any inconsistencies between Plans.
The Town of Grafton and South Grafton Levee Audit 2004 and the Grafton and Lower Clarence Floodplain Risk Management Plan 2007 listed specific recommended structural and non-structural measures for the risk management of Grafton, South Grafton and the Clarence Valley floodplain. The purpose of this project is to implement the recommended measures in the Audit and Plan regarding the issue of private buildings, which may not be flood proof, that act as a part of the Grafton Levee System. This stage of the project aims to address the issue of buildings located along the Blackwood Close section of the levee.
Most of Council’s levees have been constructed on private property without easements to protect their status or to provide ease of entry for maintenance and repair or to control building activities adjacent to the levees. Many easements have already been acquired and negotiations are underway with other property owners to acquire easements over their properties, in accordance with the overall master plan for the Grafton Levee Easement Acquisition. These negotiations are at differing stages of progress. It is planned that a number of separate easement acquisitions will be successfully completed during the 2011/2012 financial year.
In 2010 a levee overtopping analysis for Grafton, South Grafton and Maclean was completed. This project will undertake a sensitivity analysis of overtopping to determine what minor levee works can be undertaken to improve flood security of the three towns and also assist emergency authorities in better evacuation strategies in an overtopping event.
The penstocks and floodgated outlets of the drainage structures that are an essential part of the Grafton and South Grafton Levee systems do not comply with current OHS standards for access to and operation of by Council works staff for maintenance works and during extreme storm and flood events. This stage of the project is to make suitable OHS improvements for access to the Christopher Creek outlet structure for maintenance and inspection purposes.
The town of Grafton and South Grafton Levee Audit 2004 and the Grafton and Lower Clarence Floodplain Risk Management Plan 2007 listed specific recommended structural and non-structural measures for the risk management of Grafton, South Grafton and the Clarence Valley floodplain. The purpose of this project is to implement the recommended measures in the Audit and Plan commencing with those as listed as high priority. This project will complete the stability improvement works of a 50 metre section of reinforced concrete block levee wall by providing additional bearing support as well as providing a cut-off under the levee.
Parts of the Maclean levee are situated on private property without easements to protect their status, provide ease of entry for maintenance or repair or to control building activities adjacent to these levees.
The first stage of this project is for the survey of the levee to identify those sections that require easements.
This Project is an integral part of the internal drainage system within the Maclean levee. Its purpose is to adequately drain the internal catchment of the levee system of impounded stormwater blocked by high river levels or overtopping floodwater. Two studies identified that further drainage/pump improvements are required for the efficient drainage of water inside the levee (Paterson Consultants 1993 and Maclean Shire Council 1999). The Grafton and Lower Clarence Floodplain Risk Management Plan 2007 recommended the further review of the internal drainage strategy within the town, including the capacity of the existing pumps.
Recommendations from previous investigations and management plans (Paterson Consultants 1989, Paterson Consultants 1993, Maclean Shire Council 1999, Coffey 2003) are included in The Grafton and Lower Clarence Floodplain Risk Management Plan 2007 and list potential and recommended structural and non-structural augmentation measures for the Maclean Levee system. The purpose of this project is to implement augmentation measures commencing with those considered high priority. The aim of this project is to engage a suitability qualified consultant to provide a design for riverbank stability works and commence works on high priority areas.
Complete the Yamba Evacuation Capability Assessment, including sensitivity analysis through a range of time series analysis from the Grafton & Lower Clarence Flood Study.
The project is the preparation of the Boambee - Newport's Creek Floodplain Risk Management Study and Plan. Council has recently completed the Boambee - Newport's Creek Flood Study determining the nature and extent of flooding in the catchment. The area experienced significant flooding in 1996 and 2009, with Natural Disaster declarations being made in February, March, May and November of 2009.
Flooding in the catchment affects the industrial areas of Isles Dr and Cook Dr and the Coffs Area Health Campus. In the March 2009 event, the Health Campus had water lapping the entrance to the emergency unit and hundreds of cars destroyed in the campus car park. Some businesses in the industrial areas flooded 2 or 3 times in 2009 which has seriously affected profits and operational viability. The Boambee - Newport's Creek Floodplain Risk Management Study and Plan will investigate and evaluate management options for the floodplain to reduce the flood risk to the Health Campus (Coffs Base hospital and ambulance centre) and the industrial areas of Cook Dr and Isles Dr.
The project is the investigation and assessment of remedial drainage and flood mitigation works to alleviate flooding problems in the Coffs Harbour CBD. The CBD has been developed and grown over the decades and unfortunately part of the growth has been over natural overland flow paths. Major pipe drainage works have been undertaken to alleviate the problems but has limited capacity. The investigation will focus on establishing overland flow paths to compliment the pipe drainage network and explore opportunities to make the major drainage system more efficient.
This project received initial funding through the NSW State Floodplain Management Program and the Natural Disaster Resilience Grant Scheme. The basin design is nearing completion and land acquisitions are proceeding. Council is seeking to construct the basin in the dry season of 2011. The Upper Shephards Lane Detention Basin is one of four detention basins proposed in the upper catchment area of Coffs Creek. (Bakers Road Detention Basin was recently completed). Each basin is located on a separate arm of Coffs Creek. Preliminary basin details were determined using RORB hydrologic model, which was developed as part of the Coffs Creek Flood Study.
This basin will reduce the peak 100 year flood flow from 39m3/s to 20m3/s downstream of the basin; reduce the number of residential homes inundated by the 100 year flood from 308 to 236; and reduce the number of commercial buildings inundated. Should all four basins be constructed, then flood levels could reduce by up to 0.42m at Grafton Street, Coffs Harbour. This would reduce the number of houses flooded above floor level in the 100 year flood from 308 to 114 and reduce commercial/industrial properties flooded from 111 to 29.
Coffs Harbour City Council has procured a design for a flood warning system with the assistance from the Natural Disaster Resilience Grants Scheme 2010/11. Council now wishes to install the following components of the scheme including rainfall gauges and water level recorders with telemetry links back to Council, the State Emergency Service and the Bureau of Meteorology. Major flooding events in Coffs Harbour in 1996 and 2009 have caused extensive damage to local infrastructure and key services. The early warning measures and improved community awareness will help reduce the impacts of flooding and enhance recovery efforts.
Key benefits include:
The project entails an environmental assessment before embarking on detailed design of a new levee structure that will address deficiencies that have been identified in the town's existing levee.
Repair river bank eroded during 2010/11 floods using gabion baskets and selected rock fill.
This project will see the completion of the ongoing Flood Study and adoption by Council.
This project will models the Edward River floodplain at, and in the immediate environs of Deniliquin, post the newly constructed levee bank system, which has been built over a number of years from the late 1990s. There is a clear need for this review, as the last major modelling was undertaken some 27 years ago, prior to the construction of the levee system. The project will deliver outcomes that will lead to more accurate information being incorporated into Council's planning information and processing systems. This will lead to reduced flood risk to existing and future development in Deniliquin. The project will also identify any requirement to remove obsolete or redundant levees that existed prior to the construction of the new town levee system.
The flood plain management study and plan will provide important information on localised flooding in the village of Clarence Town. This area is in the process of being sewered and with the completion of this work there is expected to be a significant increase in development within the village. The community and Council need accurate data in relation to where future development will be restricted by flooding and what impact development will have on the current flood characteristics of the village.
This project will prepare a Flood Study for North Narooma. The project will include a consideration of entrance conditions in modelling flood behaviour and developing flood management options. The flood affected area captures approximately 120 residential properties with a recently recorded flood event closing the main access to the Princes Highway. The area will be significantly impacted by sea level rise with the some flood affected properties being inundated by daily tides under open entrance conditions within a 50 year planning period. The first stage of the project will:

This project will prepare a Flood Risk Management Study and Plan for Wagonga Inlet, Narooma. This is a significant flood affected area with over 200 residential lots and forty commercial properties below the 2.2m AHD flood levels. The number of habitable buildings including detached residential, medium density, affordable housing and tourism accommodation is in excess of 400. The area will be significantly impacted by sea level rise with the same flood affected properties being inundated by daily tides within a 50 year planning period. The first stage of the project will:
Stage 2 will involve the preparation of the Flood Risk Management Study and Plan.
The main objectives of this study are to review the results of the Canley Corridor Overland Flood Study and collect additional data collection to:
I
nvestigate potential impacts of climate change on the catchment.
The main objective of this project is to educate the Fairfield community about the risk of flooding in the LGA. It is proposed to engage a consultant to conduct social profiling of the city and develop (in consultation with major stakeholders including the Fairfield Floodplain Management Committee) an innovative suite of education measures for implementation.
The main objectives of this study are to draw together the results of the Three Tributaries Flood Study and undertake additional data collection in order to:
The town of Glen Innes has a population of around 6,000 and is dissected by Rocky Ponds Creek. Traditionally, floodplain development has relied on historical levels and preliminary flood investigations. Floods occur predominately without warning (less than two hours) and threaten significant infrastructure, including a day care centre, businesses, homes and public facilities. There has been increased development pressure and densities in the floodplain over recent years. The project objective is to develop a flood study for the town of Glen Innes, to determine the flood characteristics of a flood in Rocky Ponds Creek, Glen Innes, for a variety of events up to the Probable Maximum Flood (PMF). The study will consider mainstream and significant overland flooding. In particular, information will be sought to establish appropriate planning levels and enhance emergency management.
Most of the urban development surrounding Brisbane Water is on low lying flat land which was originally marshlands and swamps filled for subdivision. These areas now face numerous flooding and drainage problems due to their flatness, closeness to high tide and/or the steepness of the terrain behind. The flood study for this area has been completed which defined the flood extents for various flood events. This study will investigate various options to manage the risk of flooding and inundation of properties situated in the flood plain of Brisbane Water in accordance with the NSW Government Floodplain Development Manual. It will also recommend development controls to minimise potential damage in future flood events and will also assess climate change including sea level rise and rainfall impact to the study area.
The Foreshore areas of Davistown and Empire Bay have been subjected to flooding and inundation due to catchment rainfall and stormwater inundation from Brisbane Water. The Flood Study which is the first stage of the Floodplain Risk Management Process has determined nature and extent of flooding. Now, the management study will investigate various options to manage the risk of flooding and inundation of properties in the catchment of Davistown and Empire Bay in accordance with NSW Government's Floodplain Development Manual. And finally a management plan will be prepared which will recommend development controls to minimise potential damage in future flood events. It will also assess climate change including sea level rise and rainfall impact to the study area.
Erina Creek along with its tributaries is one of the major creeks in Gosford LGA's major urban settlement and drains into Brisbane Water. Flood studies, floodplain management studies and management plans have been completed for Erina Creek and its tributaries over the last 15 years. A review of these studies is now due, to firstly, establish the Probable Maximum Flood's behaviour which is vital to establish Flood Liable Land and secondly, to review the hydrologic and hydraulic models following flood events experienced since the completion of the studies and thirdly, to review floodplain mitigation proposals based on current regulations. The review shall reassess the extent of flood liable land in the Erina Creek floodplain and will also review management options and development controls and define the extent of the Probable Maximum Flood in accordance with the Floodplain Development Manual (2005). It will also assess climate change including sea level rise and rainfall impact to the study area.
These works form part of the Kincumber Catchment flood study to reduce the impact of property flooding in the Kincumber area. Works will include the construction of a retarding basin to control flood flows and contain these within the trunk drainage system.
Narara Creek along with its tributaries is one of the major creeks in Gosford LGA's major urban settlement and drains into Brisbane Water via Fagans Bay. Flood studies, floodplain management studies and management plans have been completed for Narara Creek and its tributaries over the last 15 years. A review of these studies is now due, to firstly, establish the Probable Maximum Flood's behaviour which is vital to establish Flood Liable Land and secondly, to review the hydrologic and hydraulic models following flood events experienced since the completion of the previous studies and thirdly, to review floodplain mitigation proposals based on current regulations. The review shall reassess the extent of flood liable land in Narara Creek's floodplain and will also review management options and development controls and define the extent of the Probable Maximum Flood in accordance with the Floodplain Development Manual (2005). It will also assess climate change including sea level rise and rainfall impact to the study area.
Henley Avenue Stage 3 drains the east side of the Terrigal Bowl sub-catchment. Underground drainage will be provided to the low points of Ash Street and Barrington Road to reduce overland flow where the grading of the drainage paths is greatly reduced.
Construct next stage of the Riviera Catchment trunk drainage system with extension along Parry Ave and Cottee Crescent at Terrigal.
The Woy Woy Peninsula area is prone to flooding especially during long-duration rain events. Flooding occurs in road reserves and numerous residential properties. The Flood Study which is the first stage of Floodplain Risk Management Process has determined the nature and extent of flooding. Now, the management study will investigate various options to manage the risk of flooding and inundation of properties on the Woy Woy Peninsula in accordance with NSW Government's Floodplain Development Manual. And finally a management plan will be prepared which will recommend development controls to minimise potential damage in future flood events. It will also assess climate change including sea level rise and rainfall impact to the study area.
The Goulburn Mulwaree Floodplain Risk Management Review and Implementation Project will update the recommendations of the 2003 Floodplain Risk Management Study and will include updated flood data (post-2003), community input and climate change modelling.
Karuah River Flood Study was completed in September 2010. In order to improve planning information it is proposed to update flood study information in line with current climate change estimates. This will be undertaken as a prerequisite and initial component to the floodplain risk management study. Climate change revision will be improved by cross-referencing Stroud and Karuah River studies. The risk management plan will provide a basis for strategic action in protection of private and public property and personal safety under a regime of gradually varying climate change impacts. In particular, flood planning levels will be produced to inform future development controls and flood response actions.
The Lower Myall River and Lakes are a dynamic and important link in management of flooding risk in Tea Gardens and Hawks Nest. This area is experiencing increased development pressure coincident with elevated risk associated with climate change and sea level rise. In particular, risk exposure in North Hawks Nest and Tea Gardens is driven in considerable part by the interaction between the Lower Myall River and the main Port Stephens waterbody. Existing flood study information is now quite dated, deriving from flood analysis performed in 1979. This work was based largely on inadequate rainfall data and quite poor anecdotal flood observations. No modelling of the Myall Lakes system was undertaken in the existing study and there is a strong possibility that the results were overly conservative.
This project will develop design flood information across the complete system under the effects of climate change and sea level rise where relevant. In particular, the proposed project will recognise the considerable long-term state investment in both natural and infrastructure assets in Myall Lakes National Park. Deriving competent flood information for the Lakes system in a time of shifting challenges will be essential in the provision of timely and cost-effective adaptations.
Primary objectives for the flood study will be:
Conduct appropriate sensitivity analyses to assess confidence and guide rapid adaptation measures if required
The study will consolidate flooding knowledge and provide planning information that is consistent with that for the Port Stephens waterbody. Council also recognises the value of integrated climate change responses in relation to natural assets, particularly in view of the international conservation importance of the Myall system. Flood study findings would further inform estuary management adaptations necessary within the Port Stephens & Myall Lakes Estuary Management framework.
Nabiac Flood Study was completed in 2009/10. In order to improve flood planning information it is proposed to update flood study information in line with current climate change estimates and government guidelines. This review is regarded as a prerequisite to the floodplain risk management phases. Climate change work will include a review of Wallamba River flood processes. The floodplain risk management study will evaluate available options to address flood impacts from the watercourses traversing the town. The risk management plan will provide a basis for strategic action in protection of private and public property and personal safety. In particular, flood planning levels will be produced to inform future development controls and flood response actions.
This project comprises three main components:
The remaining risk management components will review existing mitigation measures and provide a risk management plan to suit the identified priorities of each council. This project will be undertaken in partnership with Port Stephens Council to provide consistency in risk management planning for the waterbody as a whole. Inclusion of climate change/sea level rise conditions will also better define tailwater boundary conditions for a range of other tributary systems including Karuah River, Lower Myall River and Tiligerry Creek.
This project will comprise two main components:
A flood study for Smiths Lake was completed in September 2008. A necessary prerequisite for the management study will be a review of climate change and sea level rise effects. Risk management stages which will be addressed in a single report. Climate change review information will be attached as a separate appendix. The floodplain risk management study will evaluate available options to address flood impacts from the watercourses traversing the town. The risk management plan will provide a basis for strategic action in protection of private and public property and personal safety. In particular, flood planning levels will be produced to inform future development controls, as well as climate change and flood response actions. As such it will provide important input to the Smiths Lake Estuary Management process.
In order to improve planning information it is proposed to update flood study information in line with current climate change estimates. This is regarded as a logical prerequisite to the floodplain risk management stage. Climate change revision will be improved by combining Stroud and Karuah River studies under the following arrangement. The floodplain risk management study will evaluate available options to address flood impacts from the watercourses traversing the town of Stroud. The risk management plan will provide a basis for strategic action in protection of private and public property and personal safety under a regime of gradually varying climate change impacts. In particular, flood planning levels will be produced to inform future development controls and flood response actions.
Completion of a flood study for the township of Culcairn. The study will define the nature and extent of flooding in Culcairn which will allow for the future preparation and implementation of a floodplain risk management plan to reduce the impact from flooding on the local community.
Completion of a flood study for the township of Henty. The study will define the nature and extent of flooding in Henty which will allow for the future preparation and implementation of a floodplain risk management plan to reduce the impact from flooding on the local community.
Completion of a flood study for the township of Holbrook. The study will define the nature and extent of flooding in Holbrook which will allow for the future preparation and implementation of a floodplain risk management plan to reduce the impact from flooding on the local community.
Completion of a joint flood study for the Murray River with Albury City that was commenced in October 2010. The study will define the nature and extent of flooding on lands adjacent to the Murray River in Greater Hume Shire, and Albury City. The completion of the study will allow the preparation and implementation of a floodplain risk management plan for the Murray River as well as providing the SES with valuable data for their Flood Plans.
Greater Taree City Council has completed the Wingham Floodplain Risk Management Plan (WFRMP). The Floodplain Management Committee has now recommended this plan be adopted and funding be sought for the investigation of a flood warning system. There is a river gauge in the Manning at Wingham, however, other information from gauges on Cedar Party Creek is not available. This other main tributary to the river has a shorter time of concentration, which adds another level of uncertainty in flood assessment and management. Additional investigation using the new modelling and evaluation of records would be useful in providing more rigorous flood information from the Creek independently and also its inter-relation with the river peak. Strategic placement of flood markers will assist in providing a network of monitoring stations so that more accurate, timely and appropriate advice can be forwarded to the SES and residents.
Griffith City Council is currently undertaking the Lake Wyangan Flood Study, which is scheduled to finish by December 2011 and be adopted by Council by the end of March 2012. This project will see the continuation of the Flood Study and commencement of the Floodplain Risk Management Plan and Study for the Lake Wyangan catchments. This will determine an optimal mix of flood management options to protect properties from flood damages.
Griffith City Council is undertaking a Floodplain Risk Management Study and Plan for Main Drain J catchments. Information has shown that part of the catchment which was originally thought to be part of Main Drain J catchment is in fact draining towards Lake Wyangan. This was recently found out while defining the catchment boundary for Lake Wyangan Flood Study. The proposed study will review the latest information, and revise hydrological and hydraulic models accordingly. This study will confirm if the current design flood estimates which Council has adopted since 2006 after completion of the Flood Study needs revision. If the revision is required, Council will then need to update the Flood Study and Floodplain Risk Management Study and Plan.
Griffith City Council is currently undertaking an Overland Flow Flood Study for CBD catchments, which is scheduled to be finalised December 2011 and adopted by council by the end of March 2012. This project will see the continuation of the flood study and commencement of the Floodplain Risk Management Study and Plan for the CBD catchments. This will determine an optimal mix of flood management options to protect residential properties from flood damage and industrial and commercial outlets from flood damage and losses due to operational interruptions.
Council presently relies on the Gundagai Local Flood Plan, which was developed based on the 1980 Gundagai Flood Inundation Map. The aim is to produce a detailed Flood Study across the Gundagai Local Government Area that references all historical and current flood data, and provides detailed mapping of flood inundation along the main water courses and townships. The object of this Study is to collect all available data, develop a methodology for preparation of a detailed Flood Study, and develop a consultants brief for the Study.
The projects aims to assess the risk associated with and possible measures to alleviate the potential risk of flooding in the Tingha township along Copes Creek to minimise damage and loss that occurs to public and private property.
Council intends to update and expand the current flood study completed in 1981 to assess the impact of flooding on villages in the Gwydir River catchment.
The overall objective of the study is to develop a floodplain risk management plan for the study area that addresses the existing, future and continuing flood problems, in accordance with the NSW Government's Flood Policy, as detailed in the Floodplain Development Manual. It is expected that the overall study will be essentially undertaken in two phases:
Phase I - floodplain risk management study in which the floodplain management issues confronting the study area are assessed, management options investigated and recommendations made.
Phase II - floodplain risk management plan developed from the floodplain risk management study detailing how flood prone land within the study area is to be managed.
Undertake civil construction works resulting from the recommendations of the Evacuation Route Options Study for Bligh Park. The study was part of the Hawkesbury-Nepean Floodplain Management Strategy, which follows on from several key reports commissioned by the NSW State government. The project involves modification works, over two Stages, to the Bligh Park Pedestrian Laneway numbers 9 & 10 with the provision of an all weather hard surface as well as collapsible bollards. In addition, two provisional Link Points are at Morgan/Finnan Place and Giles/Webb Place. The Civil works will provide the SES the potential to utilise these laneways as trafficable alternative flood evacuation routes to the Rifle Range Road and Colonial Drive evacuation routes. The laneways will provide an alternative/bypass for flood evacuation route problem locations and provide exit routes from potential neighbourhood flood inundation problems connecting the eastern section of Bligh Park to evacuate via Thorley Street.
Undertake the Greystanes Creek Overland Flood study as part of the development of a floodplain risk management plan.
Undertake the Lower A'Becketts Creek Overland Flood study as part of the development of a floodplain risk management plan.
The flood study is the second stage of the Flood Risk Management process. Holroyd’s Floodplain Management Committee has recommended that the Coopers Creek catchment be the third area and Finlaysons Creek be the forth area where Overland Flood Studies will be conducted. The extent and level of the 1% flood can be placed upon Council’s GIS to speed up the DA process and to commence the Flood Risk Management Study phase.
Undertake the Prospect Creek Overland Flood study as part of the development of a floodplain risk management plan.
Undertake the Westmead Creek Overland Flood study as part of the development of a floodplain risk management plan.
Production of asset management system identifying all Hunter Valley Flood Mitigation scheme assets.
Undertake rehabilitation works for Hunter Valley Flood Mitigation assets which are at the end of their design life.
This study will investigate the feasibility of constructing three detention basins within the greater Junee township area. This study was highlighted as being of high importance in the Lower Butlers Gully Floodplain Risk Management Plan. It will refine the hydrologic, hydraulic and cost-benefit analyses that were presented in the Risk Management Plan as well undertake preliminary geotechnical analysis of the three sites. The study will also address environmental factors, with a view to capitalising on opportunities to improve the environment at the various sites and ensuring any effects on the environment downstream will not be to its detriment.
The Kempsey CBD Flood Study was adopted by Council in September 2009. The next stage is to prepare a Floodplain Risk Management Plan for the Kempsey CBD.
Council is responsible for 181 floodgated structures with 352 floodgates. A review of floodgate structures is required to ensure that essential works are determined and that these are prioritised and identify the need for repairs and rehabilitation of the gates to ensure they remain watertight and treat concrete "cancer".
The project involves implementing the structural flood modification measures identified in Council's adopted Floodplain Risk Management Plan, including a partial ring levee and additional Fawcetts Creek flood breakout.
