Albury City floodplain risk management study and draft plan
Funding: $200,933 (SFMP)

A floodplain risk management study and plan will be developed for Albury City Council’s urban and future urban areas in accordance with the NSW Government’s Floodplain Development Manual. The first stage has been undertaken with the completion of flood studies for Thurgoona and Airport creeks, Bungambrawatha Creek, Lavington, South Albury and West Albury catchments, Eight Mile Creek, and the Murray River from Hume Dam to Greater Hume Shire. These studies cover potential flooding from the Murray River and its tributaries and major overland flows through the urbanised and future growth areas of Albury. The study will collate the data and information from the current flood studies, review the council’s planning policies and identify and assess the effectiveness of existing and proposed works, measures and restrictions to assist the council in the long-term management of flood risks throughout Albury.

Armidale Dumaresq Council

Review and update of Armidale floodplain risk management study
Funding: $80,000 (FRMGS)

The project is a review and update of the Armidale Floodplain Management Study (now called a floodplain risk management study) prepared in 1994 and updated in-house by the council in 1999. It assesses flood impacts from Dumaresq Creek and a number of minor tributaries to Dumaresq Creek within the urban area of Armidale. Updating the risk management study has become a priority for Armidale as a consequence of a recent high-profile commercial development proposal on land which is significantly flood liable. Public safety, including the safety of rescue personnel, in a major flood is the main issue of concern. This proposal has highlighted the need to review and update the council’s floodplain risk management study and plan to better address this and other concerns for development on flood liable land in Armidale.

Ashfield Council

Ashfield Council: Dobroyd Canal flood study
Funding: $40,000 (FRMGS)

Dobroyd Canal drains a catchment of approximately 8 square kilometres in Sydney's inner west, mainly within Ashfield Council’s local government area. While Dobroyd Canal is a manufactured open channel, the main flow branches upstream are serviced by significant subsurface trunk drainage assets. The study will focus on this trunk drainage system and the modelling of the associated overland flow. The results of the study will provide flood information on the entire modelled area, and flood information derived from trunk drainage, and overland flow. The results of the study will be subject to community consultation and public exhibition and will be incorporated into the council’s planning flood maps and development controls. Sydney Water, owner of the trunk drainage system in the catchment, will undertake a flood study of its trunk main and Dobroyd Canal as part of its asset management program. Ashfield Council will use this core flood model and extend it into a catchment overland flood study.

Auburn City Council

Detailed review of Haslams Creek Floodplain Risk Management Plan
Funding $30,000 (FRMGS)

The council is completing a review of Haslams Creek Floodplain Risk Management Study and Plan.  This includes incorporating existing TUFLOW  subcatchment studies into the current HEC RAS study and extending the TUFLOW model to the entire Haslams Creek Catchment. Risk management options will also be reviewed. This grant will fund the investigation of flood mitigation options and construction works. Funding is provided to commence the review of the Haslams Creek Floodplain Risk Management Study and Plan.

Design and documentation of Lidcombe town centre flood mitigation option
Funding $50,000 (SFMP)

Haslams Creek Floodplain Risk Management Study and Plan 2003 identified a duplicating of culverts from James Street to Church Street to reduce flood risk. In 2005, the council carried out a TUFLOW model in Lidcombe town centre which reduces flood levels significantly. Funding is limited to the investigation and design of the proposed duplicate culvert.

Bankstown City Council

Catchments of the mid-Georges River floodplain risk management study and plan
Funding $120,000 (SFMP)

The grant will provide funding for implementing recommendations of the floodplain risk management study and plan for subcatchments of the mid Georges River, which recommend 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 local government area-wide planning controls developed as part of the Salt Pan Creek Floodplain Risk Management Study and Plan, including changing controls as a result of assessing susceptibility to climate change.

Bathurst Regional Council

Implementation of Sofala vegetation management plan
Funding: $20,000 (FRMGS)

Sofala is located 42 kilometres north of Bathurst on the Turon River and has experienced a number of flood events. The implementation of the Sofala vegetation management plan will effectively manage the native and introduced vegetation within the riparian corridor, including vegetation 1,500 metres upstream and 500 metres downstream of Crossleys Bridge on the Turon River. The intention is to reduce flooding impacts during large events to the village of Sofala. Funding is limited to a feasibility study to test the viability of this management option.

Implementation of Georges Plain flood mitigation
Funding: $20,000 (FRMGS)

The aim is to restore the capacity of Georges Plain Creek so nuisance flooding of flood-prone properties in Georges Plain can be reduced. The creek channel has been filled with deposited sediment and choked with vegetation including weeds, thus reducing the effective flow capacity. The scope of works includes clearing creek vegetation, clearing debris under the bridge located on Main Road 54, and formalising the irregular creek channel into a regular creek channel over a length of approximately 930 metres. Funding is limited to a feasibility study to test the viability of this management option.

Bega Valley Shire Council

Bega and Brogo Rivers flood study at Bega
Funding: $80,000 (FRMGS)

This project will update existing flood mapping within the Bega township and surrounding villages to the standards of the NSW Floodplain Development Manual. Hydrological and 2D hydraulic models of the existing flood behaviour of the Bega and Brogo river catchments will be created and flood frequency analysis undertaken to update events since the production of the 1979 Water Resources Commission Inundation Map for Bega.

Bellingen Shire Council

Lower Bellinger and Kalang rivers flood study
Funding: $84,000 (SFMP)

Bellingen Shire Council is producing a flood study for the Bellinger and Kalang rivers that encompasses the towns of Bellingen and Urunga. The project will produce detailed flood and hazard information for the study area, including updated information relating to climate change and sea level rise.

Blacktown City Council

Eastern Creek floodplain management planning study
Funding: $200,000 (SFMP)

NSW Government planning has identified the North West Growth Centre and the Western Sydney Employment Area as major new growth centres in the Sydney region. Substantial areas of these centres are located in 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 the development of effective policies to protect the future needs of the new communities.

Blayney Shire Council

Blayney (town) flood study and management study: Belubula River
Funding: $100,800 (SFMP)

Through this project, a flood study for Belubula River in the town of Blayney will be prepared. The flood study is the first stage in informing the floodplain risk management study and plan. The flood study will also inform the new principal LEP for Blayney Shire, and provide technically sound information for the Blayney Shire Local Flood Plan prepared by State Emergency Services.

Blue Mountains City Council

Lapstone, South Glenbrook and South Blaxland floodplain risk management study and plan
Funding: $80,000 (SFMP)

The council received a grant under the NSW Floodplain Management Program 2010 to undertake a floodplain risk management plan for the Glenbrook-Erskine Creek Catchment within the Blue Mountains local government area. The flood study for this catchment was completed in April 2012. To complete the floodplain risk management process, the council will now undertake the floodplain risk management study and plan for the catchment.

Hazelbrook Creek and Woodford Creek Catchment overland flow path study
Funding: $19,467 (FRMGS)

The council’s registrar indicates Hazelbrook (Hazelbrook Creek and Woodford Creek Catchment) has the highest flood-related issues in the Blue Mountains local government area. 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) after the February 2010 storm. The council will undertake an overland flow path study to understand the extent and hazards of the flooding to reduce the danger of damage to property and personal safety, and ensure future development is compatible with the flood risk. A floodplain risk management plan will be developed once the overland flow path study is completed.

Bogan Shire Council

Bogan River floodplain study: Nyngan
Funding: $64,286 (FRMGS)

The council will undertake a study to assess floodplain levels in a residential zoned area which will enable building and development standards, including floor levels, to be established under the council’s DOP. The design of other infrastructure such as roads will also be able to take into account flood levels and frequency of flooding.

Bombala Council

Bombala floodplain management plan
Funding: $13,334 (FRMGS)

Through this project, a comprehensive floodplain risk management plan will be produced for Bombala River at Bombala.

Botany Bay Council

Flood study for City of Botany Bay suburbs: Mascot, Eastlakes and Rosebery
Funding: $150,000 (FRMGS)

Presently, the City of Botany Bay Council does not have any flood study of the local government area (LGA) which is based on section 1.1 (NSW Flood Prone Land Policy) and the principles of the Floodplain Development Manual and the accompanying Guideline on development controls on low flood risk areas. The council’s current flooding map is based on separate ad-hoc flood studies undertaken to supplement individual development applications over an extended period of time (the council’s flood map existed before 1995). It has been demonstrated by council engineers that the information in this flood map does not reflect the current flooding impacts within the LGA. As a result, the council needs to undertake this flood study in accordance with the Floodplain Development Manual.

Brewarrina Shire Council

Flood protection levee for Whytabalah Aboriginal Village
Funding: $85,714 (SFMP)

During the past three years, Whytabalah Aboriginal Village has experienced three major flood events in January 2010, March 2011 and December–February 2012, resulting in the community having to be evacuated three times. Through this project, a flood protection structure will be designed to protect Whytabalah Aboriginal Village from large floods. Actions will include surveying the existing structure, consulting with the community, proposing an improved levee structure to protect the community from large floods, developing design and engineering drawings, and producing a final report and recommendations on how to source funding and construct the levee.

Burwood Council

Burwood Council: Dobroyd Canal flood study
Funding: $30,000 (SFMP)

This project involves preparing an overland flood study which will include hydrological and hydraulic modelling and a sensitivity analysis of assumptions on the level of blockage; minimum depth of flow mapped, adopted freeboard; and the location of stormwater pipes adjacent toand through a property. Ground-truthing will be undertaken in areas the flood study identifies as having a high level of risk exposure, or in order to eliminate or confirm flow paths for affected properties, especially properties not located near a defined drainage path. The impacts of climate change will be assessed according to the sea level rise planning benchmarks listed in the NSW Sea Level Rise Policy Statement (Department of Environment, Climate Change and Water 2009). There will be community consultation on the draft study and mapping undertaken through the study will be incorporated into the council’s planning flood maps and development controls. Sydney Water is the owner of the trunk drainage system in the catchment and is expected to undertake a flood study of its trunk main and Dobroyd Canal, as part of its asset management.

Burwood Council Cooks River overland flood study
Funding: $60,000 (FRMGS)

Through this project, community consultation will be undertaken and planning controls will be placed on properties recently identified as flood-prone due to mainstream flooding. An overland flood study will be prepared which will include hydrological and hydraulic modelling and a sensitivity analysis of assumptions on the level of blockage; minimum depth of flow mapped, adopted freeboard; and the location of stormwater pipes adjacent to or through a property. Ground-truthing will be undertaken in areas the flood study identifies as having a high level of risk exposure, or in order to eliminate or confirm flow paths for affected properties, especially properties not located near a defined drainage path. The impacts of climate change will be assessed according to the sea level rise planning benchmarks listed in the NSW Sea Level Rise Policy Statement (Department of Environment, Climate Change and Water 2009). There will be community consultation on the draft study and mapping undertaken through the study will be incorporated into the council’s planning flood maps and development controls.

Byron Shire Council

North Byron coastal creeks flood study
Funding: $20,000 (FRMGS)

The council has an old flood model for Brunswick River covering the towns of Mullumbimby and Brunswick Heads. During 2008, the council completed airborne laser scanning of the area, including preparation of 250-mm contours, Digital Elevation Model and Digital Terrain Model. In February 2010, the council adopted the Coastal Creeks Flood Study, which was a joint study between Byron Shire Council and Tweed Shire Council. The 2010 Coastal Creeks Flood study includes the Marshalls Creek Floodplain, which is hydraulically connected to the Brunswick River. The study recommended that the council combine the Coastal Creeks Flood Study model with a model that covers the Brunswick River, to properly understand the hydraulic link. As a result, this project involves developing a new flood model for Brunswick River, which will provide more detailed flood levels, consider the effects of climate change, and allow development to be assessed using appropriate flood planning levels and flood hazards. The council has engaged consultants to develop the flood study which is expected to be completed by February 2013.

Belongil Creek floodplain risk management study and plan
Funding: $50,000 (FRMGS)

The Belongil Creek Flood Study (2009) was adopted by the council on 12 November 2009. This document includes an assessment of the possible effect climate change may have on flooding in the catchment. The council has now engaged consultants to complete a floodplain risk management study and plan for Belongil Creek which is expected to be completed by May 2013.

Cabonne Council

The investigation, design and construction of a levee at Molong will prevent floodwater diverting across railway tracks and inundating the lowercentral businessdistrictof Molong. A levee will retain floodwater within the channel of Molong Creek. Funding has been awarded to undertake a feasibility study of the proposal.

Camden Council

Upper South Creek floodplain risk management study and plan
Funding: $80,000 (SFMP)

The study area is rapidly developing with South West Growth Centre development. Five precincts are currently under construction and 70,000 new dwellings are proposed to be built in the Upper South Creek Catchment in Camden's local government area. The key priority for Camden is to prepare development controls to assess and address the cumulative impacts of filling in the floodplain, and filling and development in the Upper South Creek Catchment. The floodplain risk management study and plan will provide a strategic framework for appropriate development of the Upper South Creek Floodplain and South West Growth Centre.

Narellan Creek flood study review and climate change impact analysis
Funding: $75,000 (FRMGS)

This flood study is to adequately define flood behaviour in the Narellan Creek Catchment. The study will produce information on flood levels, velocities, flows, provisional hydraulic and hazard categories; and a sensitivity analysis on a full range of potential flood events under existing catchment and floodplain conditions. The events of interest include the 5%, 2%, 1%, 0.2% AEP events, together with the probable maximum flood and climate change scenarios.

Nepean River flood study and climate change impact analysis
Funding: $96,000 (SFMP)

Through this study, existing and new data will be used to adequately define flood behaviour in the Nepean River Catchment in the Camden local government area, and the potential impacts of climate change will be modelled. The study will produce information on flood levels, velocities, flows and hazard categories; and a sensitivity analysis on a full range of potential flood events under existing catchment and floodplain conditions. The study area is within a high priority area as urban population expansion is expected to increase.

Campbelltown City Council

Bow Bowing/Bunbury Curran Creek flood studies
Funding: $100,000 (SFMP)

This project comprises the preparation of flood studies for 12 subcatchments as part of the floodplain risk management studies and plans in accordance with the Floodplain Development Manual. It is not possible to complete all the studies at one time and the program allows the council to be flexible and responsive in the approach taken. Eight studies are nearing completion and through this project, the remaining four studies will be undertaken.

Canterbury City Council

Cooks River floodplain risk management study and plan
Funding: $160,000 (FRMGS)

The Cooks River Catchment is located in south-west Sydney, and has an area of approximately 102 square kilometres with flows to Botany Bay at Tempe near Sydney Airport. The Cooks River has two major tributaries: Wolli Creek and Alexandra Canal. Bardwell Creek forms a tributary to Wolli Creek. There are some small tributaries like Cup and Saucer Creek, Muddy Creek, Cox's Creek and also several unnamed stormwater channels that discharge into Cooks River. The scope of this project includes:

  1. Preparation of a flood risk management study (FRMS) that identifies a range of floodplain risk management measures to address the problems for the study area that have been identified in the Cooks River Flood Study undertaken by Sydney Water Corporation.
  2. Preparation of a floodplain risk management plan (FRMP) that documents ways in which the project measures identified in the FRMS will be implemented in terms of timing and resources.

Salt Pan Creek floodplain risk management study and plan
Funding: $54,000 (FRMGS)

The City of Canterbury commissioned WMA Water to carry out a flood study of the Salt Pan Creek Catchment area. The study, completed in September 2010, provided details of historical floods and hydrologic and hydraulic modelling of the area. The council has now engaged a consultant to develop a floodplain risk management study and plan to address the existing, future and continuing flood problems of the catchment in accordance with the NSW Government’s Flood Policy. The main objectives of this work are:

  1. Preparation of a FRMS that identifies a range of floodplain risk management measures to address the problems for the study area as identified in the 2010 Salt Pan Creek Flood Study.
  2. Preparation of a FRMP that documents ways in which the project measures identified in the FRMS will be implemented in terms of timing and resources.

Carrathool Shire Council

Lachlan Street levee strengthening
Funding: $639,249 (FRMGS)

The Lachlan Street levee will protect the western section of Hillston from river flooding. The levee will be constructed to withstand the 1:100 ARI event and will have a 400-mm freeboard. A freeboard analysis has been carried out by NSW Public Works. As the levee is predominately on private land, easements will be created to give the council access and protect the structure from damage. When complete, the levee, in conjunction with the Hillston eastern levee, will protect all of Hillston from 1:100 ARI flood events.

Cessnock City Council

Black Creek Stage 2 (North) flood study
Funding: $100,000 (SFMP)

Through the Black Creek Stage 2 (North) project, a flood study will be completed for an area of Black Creek Catchment covering Nulkaba in the south to Branxton in the north. Through the flood study, the area will be completely flood mapped and strategies recommended to to assist council with strategic planning. This area has been nominated for significant projects, with the announcement of the Huntlee Town Project aiming to provide homes for 15,000-20,000 residents. The Hunter Expressway will be completed in December 2013. It will be beneficial to have a comprehensive flood study which incorporates this new infrastructure in Branxton and North Rothbury, and the study will help determine future flood flows, flooding mitigation, overland flow sites and the effects of such infrastructure. It will also assist with future strategic planning guidelines for the northern area of Cessnock local government area.

Cessnock City flood risk management study and plan, Stage 2
Funding: $55,000 (FRMGS)

The Cessnock City flood risk management study and plan will investigate the possible flood mitigation options for the council for this area of Cessnock central business district and adjoining suburbs in the Black Creek Catchment. This Stage 2 project will be carried out in accordance with the NSW Floodplain Development Manual] and will involve:

  1. Reviewing the recent Black Creek Flood Study (2010), checking all flood event levels and all hazards areas (low-high), and confirming floodway extents.
  2. Investigating and providing 10-12 options for flood mitigation including structural and non-structural options, providing emergency management options, and providing important land development data to allow the council to determine future development and planning for the floodplain area of Black Creek, within the populated areas of Abermain, Weston, Kurri Kurri and Buchanan.

Wallis, Swamp and Fishery creeks flood risk management study and plan
Funding: $60,000 (FRMGS)

The Wallis, Swamp and Fishery Creeks flood risk management study and plan will enable the council to investigate the possible flood mitigation options for this area of Cessnock central business district and the adjoining suburbs in Black Creek Catchment. This Stage 2 project will be carried out in accordance with the Floodplain Development Manual and will involve:

  1. Reviewing the recent Wallis, Swamp/Fishery Creeks flood study (2011) by Worley Parsons, reviewing all flood event levels and all hazards areas (low-high), and confirming floodway extents.
  2. Investigating and providing 10-12 options for flood mitigation including structural and non-structural options, providing emergency management options, and providing important land development data to allow the council to decide on future development and planning for the floodplain area of Wallis, Swamp/Fishery Creeks, and the populated areas of Abermain, Weston, Kurri Kurri and Buchanan.

City of Sydney Council

Sydney City Catchments flood study
Funding: $140,000 (SFMP)

A flood study will be undertaken, and will 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/1D flood model for the entire study area. The 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.

Blackwattle Bay Catchment Floodplain Risk Management Study and Plan
Funding: $140,000 (SFMP)

This project will prepare the Floodplain Risk Management Study and Plan for the Blackwattle Bay Catchment. The study will investigate all available floodplain management options (structural and non structural), recommend flood mitigation solutions and adopt a practical FRMP for the catchment, addressing community needs.

Johnstons Creek Catchment Floodplain Risk Management Study and Plan
Funding: $140,000 (SFMP)

This project will prepare the Floodplain Risk Management Study and Plan for the catchment. The study will investigate all available floodplain management options (structural and non-structural), recommend flood mitigation solutions and adopt a practical FRMP for the catchment which addresses community needs.

Clarence Valley Council

Grafton levee access easement
Funding: $15,000 (SFMP)

Most of the council’s levees have been constructed on private property without easements to protect their status, provide ease of entry for maintenance and repair, or to control building activities adjacent to these levees. Many easements have already been acquired and negotiations are under way 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.

Clarence Valley floodplain climate change assessment
Funding: $26,666 (SFMP)

The Lower Clarence Flood Study Review was prepared in 2004 and produced a 2D flood model. This model 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 is to undertake a climate change risk sensitivity analysis of this model to assess ways in which 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.

Glenreagh flood study
Funding: $13,333 (SFMP)

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 Government have provided funding for a flood study and floodplain risk management study and plan. Coffs Harbour City Council has undertaken a flood study for the section of the Orara River in that council area. The first stage of this project was to undertake a flood study for the downstream section, which includes the village of Glenreagh. The next stage will be to develop a floodplain risk management study and plan.

Complementary drainage works
Funding: $60,000 (SFMP)

The council has opened up over 80 flood-gated watercourses. In some cases, this work has not adequately addressed the issue of flooding behind the gate due to either unforeseen events or funding shortfalls. Landowners have found that gates cannot be left open for extended periods without them being constantly checked, due to the risk of tidally induced flooding. The result has been that some gates have only been opened infrequently and for short durations. This project aims to improve the environmental management of back swamp areas and those sections of the drain behind the floodgates. Works will be undertaken on drains and watercourses that have existing drain management plans.

Grafton and Lower Clarence Floodplain Risk Management Plan: review Brushgrove mitigation measures
Funding: $10,000 (FRMGS)

Brushgrove forms part of the locality covered by the Grafton and Lower Clarence Floodplain Risk Management Plan (2007). The recommended flood mitigation method for the village (voluntary house raising) was based on public consultations held in 1997. Community representatives have advised the council that this is no longer considered the appropriate method and that there is strong support for a levee. This review will involve a detailed public consultation process to gauge community opinion and to inform a review of the original cost-benefit analysis.

Grafton levee penstocks refurbishment
Funding: $120,000 (SFMP)

The penstocks and flood-gated outlets of the drainage structures that are an essential part of the Grafton and South Grafton levee systems do not comply with current WHS standards for access to, and operation of, by council staff to perform maintenance, and during extreme storms and floods. On completion of this project, all the penstock and floodgates associated with the Grafton and South Grafton levee systems will have safe working platforms and handrails that comply with WHS standards.

Maclean levee Essex drain rehabilitation
Funding: $500,000 (SFMP)

This will aid drainage of the internal catchment of the Maclean levee system of impounded stormwater blocked by high river levels and floodwater, should an overtopping of the levee occur that would affect the commercial and residential areas of Maclean. 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. The desirability of drainage improvements was reiterated both in the Floodplain Management Study (Paterson Consultants 1993) and the Floodplain Management Plan (Maclean Shire Council 1999). A review of the Maclean Levee drainage system is underway which will address drainage issues in the Essex drain and ensure a constant adequate supply of impounded water to the drain's flood pump.

Maclean levee rehabilitation
Funding: $600,000 (SFMP)

The Grafton and Lower Clarence Floodplain Risk Management Plan 2007 lists potential and recommended structural and non-structural augmentation measures for the Maclean levee system. The Maclean Riverbank Stability and Levee Structural Integrity Investigation Study identified that the entire section of riverbank along the mass concrete levee wall to the north of the Fish Co-Operative building is at risk, due to scouring and undercutting, potentially causing slips that will risk the stability of the levee. A geotechnical report on the stability of the flood levee and riverbank commissioned in 2011 has recommended options for works to improve riverbank stability. This project is to commence easement acquisition of identified properties.

Grafton and Maclean flood levee overtopping
Funding: $38,000 (FRMGS)

In 2010, a levee overtopping analysis for Grafton, South Grafton and Maclean was completed. This project will involve a sensitivity analysis of overtopping to determine what minor levee works can be undertaken to improve flood security of the three towns and assist emergency authorities in better evacuation strategies in an overtopping event.

Maclean levee easements
Funding: $30,000 (SFMP)

Parts of the Maclean levee are situated on private property without easements to protect their status; these easements provide ease of entry for maintenance and repair and to control building activities adjacent to these levees. Progress is constrained by lack of responsiveness of land holders, from whom the easements are being sought, and where applicable, their solicitors. The council’s property section manages the Easement Acquisition Program as one of its major priorities. Through this project, easement acquisition of identified properties can commence.

Coffs Harbour City Council

Coffs Creek Flood Study review: Stage 2: 2D modelling of CBD
Funding: $60,000 (FRMGS)

Council had a 1D model of Coffs Creek completed in 2001. It was identified that the model had limitati ons, particularly modelling overland flow paths, but it was difficult to improve this without a detailed and costly survey. Since the model has been completed, the council has obtained an ALS (or Lidar) survey of the catchment, suitable for 2D flood modelling and obtained funding to model the mid-reaches of the catchment. The aim of this project - Stage 2 of the flood study review – is to extend the 2D modelling of Coffs Creek to include the central business district and northern tributaries of Coffs Creek. The 2D model will allow the council to revise flood behaviour following construction of major flood mitigation works. One detention basin has already been completed. Future works include more detention basins. The council will also review and investigate other flood mitigation options.

Park Beach major drainage augmentation detailed design
Funding: $20,000 (FRMGS)

Local rainfall events flood roads and inundate residents and businesses in the Park Beach area, and local runoff flows into ponds in the low-lying areas, due to the flat grades and limited drainage infrastructure capacity. As a result, the Park Beach area acts like a basin that fills with flood waters and takes a relatively long time, considering the size and nature of the catchment, to drain or recede. The project will involve a major augmentation of the drainage infrastructure in Park Beach that will reduce peak flood levels, the number of properties inundated, and the time of inundation in flood events.

The objective of this project is to complete the floodplain risk management study and plan based on tasks that have already been undertaken.

Narara Creek floodplain risk management study and plan
Funding: $191,600 (SFMP)

Flood studies have been conducted for each major subcatchment of Narara Creek. However, these studies are now more than 10 years old and need to be reviewed and updated. Previous flood studies split Narara Creek into upper and lower sections and tributaries, treated as separate study areas. Through the floodplain risk management study and plan, management options will be developed that will address existing flood behaviour and identify the continuing risks associated with events greater than 1% annual exceedence probability. To address future risk, the council will examine current development controls to ensure that flood extents identified in the flood study are accommodated in LEPs. The council will also examine the potential for the proposed RTA upgrade options currently on exhibition to form part of any future evacuation routes. During the development of the plan, the council will utilise the NSW Floodplain Development Manual and consult more widely with the community and other agencies.

This project involves modification works over two stages (2011-2012 and 2012-2013) to the Bligh Park Pedestrian Laneway numbers 9 & 10, through the provision of an all-weather hard surface and collapsible bollards. In addition, two provisional link points are at Morgan/Finnan Place and Giles/Webb Place.

The civil works will provide the SES with the potential to utilise these laneways as trafficable alternative flood evacuation routes to the Rifle Range Road and Colonial Drive routes.

Hay Shire Council

Hay levee rehabilitation pre-construction activities
Funding: $616,757 (SFMP)

This project involves rehabilitating older levees which were constructed under emergency conditions before the 1956 Murrumbidgee River flood, and raised/reinforced before the 1974 flood. Recent events and investigations suggest that the existing levee system protects the community from a flood event of approximately a 1- in- 20 year recurrence interval. The proposed new levee system will raise the level of protection to the approximate equivalent of a 1-in -100 year event. Such a level of protection will greatly enhance the security of public and private property in a town of nearly 3,000 people, which also provides a vital service centre for rural residents within a radius of 100 km.

All studies will incorporate the sea level rise benchmarks in the NSW Flood Risk Management Guide.

Ku-ring-gai Council

Blackbutt Creek Catchment flood study
Funding: $100,000 (SFMP)

Steep terrain and ridge-top development has led to major flood risk in Ku-ring-gai, arising from flash flooding along headwater streams and drainage depressions. The speed with which the flooding occurs means that there is usually no time for damage reduction measures to be put in place, or for evacuation to be undertaken as required. The Blackbutt Creek Catchment is one of Ku-ring-gai’s most significantly flood affected areas. The complex nature of flash flooding events means that the council has not previously had the resources to undertake detailed local mapping to provide information to inform flood risk management planning.  This project will provide a flood study that can be used as the basis of the flood risk management process, and provide sufficient data to undertake a flood risk management study and plan to guide future flood risk management actions.
