Bathurst Regional Council

Bathurst flood plan update

The primary flood areas through Bathurst are along the Macquarie River, extending from the White Rock/Perthville tributary locations to Eglinton. The current plan was developed in 1993 to determine levee locations and enable management in the interim. The entire levee system has been constructed, and the Bathurst development area has extended beyond the original plan's footprint.

This project will update the flood plan, validate the levee system, implement modern industry standards, understand flood risk from overland flow and enable council to make informed decisions on managing flood risk in developed and soon-to-be developed areas.

Bayside Council

Feasibility study and concept design of floodplain risk management options – Botany Bay Foreshore Beach catchment

This study will investigate the feasibility and prepare a concept design for the 3 structural mitigation options which were identified in the Botany Bay and Foreshore Beach floodplain risk management study. The consultant identified 3 options which could substantially improve existing flood risk and reduce future flood damage:

• a detention basin option in Booralee Park
• a drainage amplification option in William Street
• a drainage upgrade in Dent Street with tidal backflow devices option.

Bega Valley Shire Council

Bega and Brogo rivers floodplain risk management plan emergency access upgrade stage 2

This project involves completing the remaining road raising, culvert augmentation and intersection adjustments at Newtown Road and Tathra Road, to secure flood free all-weather access to the adjacent South East Regional Hospital.

Bland Shire Council

Ungarie voluntary house raising/purchase feasibility assessment

Ungarie has major flood inundation issue with over 80 residential and 20 commercial properties subject to flooding by Humbug Creek. The floodplain risk management study and plan highlighted the highest priority action to deal with this as being voluntary house raising or voluntary house purchase. A feasibility study is the next step to be completed. This feasibility study will investigate eligible houses and develop a fully prioritised scheme ready for implementation.

Blue Mountains City Council

North Katoomba and North Leura flood study and floodplain risk management study and plan

The catchments of North Katoomba and North Leura have a strong need for a floodplain risk management study, as undeveloped land is being developed at a high rate. Council is not currently able to provide flood related planning statements on section 10.7 planning statements, and there is a need for these to support development applications. Overland flow flooding is known to occur in several locations in the catchments. This project will include a flood study and a floodplain risk management study and plan for these areas.

Bourke Shire Council

This flood risk management study and plan will encompass the above 4 mentioned catchments, it will evaluate the flood risks and eventually prioritise flood risk management works to alleviate flooding and its effects.

Byron Shire Council

Debris control measures for Federation Bridge

Federation Bridge is the major bridge in Mullumbimby crossing the Brunswick River. Federation Bridge's pile design makes the structure vulnerable to the collection of debris, which causes a major blockage to floodway flow in the Brunswick River at Mullumbimby. This was a contributing factor to the increase in flood levels within Mullumbimby during the 2017 flood event. This project will undertake the investigation, design and construction of bridge control measures to reduce the potential of river blockage at Federation Bridge.

Camden Council

Detailed overland flow study of Narellan Creek catchment/Nepean River

This project will undertake a detailed overland flow study, to classify and quantify the overland flow in the Narellan Creek catchment. A detailed overland flow study is required to understand the overland flow behaviour in the catchment, to provide overland flow information to the public, for council issuing planning certificates, application of development controls and emergency management planning in existing and future developments.

Carrathool Shire Council

Hillston riverbank stabilisation works construction – stage 4

Sections of the Lachlan riverbanks at Hillston are unstable and eroding, threatening the structural integrity of the existing levee banks that protect the township. A feasibility study identified sections of the bank that require stabilisation, and the subsequent detailed design of the riverbank stabilisation works is complete. This project is for construction work to stabilise the two areas (HL1 and HL2).

Rankins Springs flood study/floodplain risk management study and plan

The township of Rankins Springs has been subject to flash flooding events. This project will develop a full 2 dimensional flood model for the area and then develop a floodplain risk management study and plan, to develop a list of floodplain management measures, planning controls and emergency response measures designed to lessen the impact of future floods.

Central Coast Council

Review and update of 1994 Tuggerah Lakes flood study

Tuggerah Lakes occupies an area of approximately 80 square kilometres and comprises of Tuggerah Lakes, Budgewoi Lake and Lake Munmorah and the immediate floodplain.

A flood study for Tuggerah Lakes was completed in 1994, and a floodplain management study and plan were completed in 2014. This review will provide updated information and modelling results to understand the interaction between lake flooding and opening of the entrance channel.

Cessnock City Council

Black Creek stage 2 floodplain risk management study and plan

A floodplain risk management study and plan will be developed for the lower Black Creek catchment. A flood study was completed for the area in 2015, providing council with important flood mapping data. The study identified the extent of flooding however, the associated risks and appropriate mitigation strategies remain unknown.

The floodplain risk management study and plan for the Black Creek catchment will investigate flood risks and develop options to manage those risks. A strategy comprising of suitable implementation actions will also be developed.

Greta floodplain risk management study and plan

The Greta flood risk management study and plan will address flood risk in the Anvil Creek catchment, which includes the townships of Greta and East Branxton.

The alerting mechanism of the system will also be upgraded to provide targeted alerts, with improved lead-time to the NSW State Emergency Service and expanded to include an opt-in system for the community.

Moonee Creek flood study review

Four main tributaries make up the catchment including Moonee Creek, Sugarmill Creek, Cunninghams Creek and Skinners Creek. The existing Moonee Creek flood study was completed in 1998. Since then, significant development has occurred within the floodplain and there is significant development pressure. The study will provide current, detailed, and accurate flood mapping that the council requires to better understand flood behaviour in the catchment. Better flood mapping provides a sound base for implementation of council's flood planning controls and better informs strategic plans for improving flood immunity.

North Boambee Valley detention basin

The North Boambee Valley Detention Basin was a recommended flood mitigation measure of the 2016 Boambee-Newports Creek floodplain risk management plan, council will implement this mitigation measure. The basin will reduce flooding to premises and dwellings in the downstream catchment, and reduced flood damages in the commercial areas of Isles Drive, Mansfield Drive and Cook Drive, and provide improved flood access to the hospital.

• an improved ENVIRONMON system with enhanced capabilities.

The outcome will be a full working network of gauges and consistency with the current intermittent flood infrastructure.

MidCoast Council

Taree central business district levee feasibility study and heritage impact assessment

This project is a feasibility study for constructing a levee to protect the Taree central business district against a 1% annual exceedance probability flood event. This feasibility study will examine various levee options and consider heritage, socio-economic and environmental factors, flood impacts and community acceptance.

Upgrade of Croakers Creek flood gate

The Croakers Creek flood gate was constructed in the late 1920s and has exceeded its planned design life. It requires an upgrade or replacement to provide flood mitigation to the area. Such an upgrade will reduce the impacts of existing flooding, flood liability on communities, as well as private and public losses resulting from floods.

The Oxley Island Drainage Union, which was established in 1930 to run the flood gate and drainage network, will partner with council on this project.

Nambucca Valley Council

Upgrade to Councils flood warning system stage 2 – installation of 1 rainfall gauge at Warrell Creek

This project will install an additional flood gauge in the Nambucca River gauge system at Warrell Creek.

Bayside Council

Feasibility study/concept design of drainage network upgrade for 3 catchments

The Mascot, Rosebery, Eastlakes floodplain risk management study (2018) analysed the drainage network in Hollingshed Street and Baxter Road areas. It found that the capacity of this system was exceeded in flood events as small as the 0.5 exceedance per year. The capacity of this drainage network relative to the land use in the area was identified as a key cause of the flood problem.

Investigation into duplicating the drainage network was undertaken and the preliminary findings show that this will eliminate flooding for 32 properties in a 1% annual exceedance probability (AEP) event and 64 properties in a 10% AEP event.

This project will produce a concept design and feasibility study for duplication of the drainage network and undertake community consultation to show the local community how Council is resolving flooding issues in this catchment.

Review of floodplain risk management studies to form a consolidated plan

This project will undertake a review of the Australian Rainfall and Runoff 2016 sensitivity for the 3 catchments and produce a consolidated flood risk management plan for Bayside west (west of the Cooks River).

Greater Hume Shire Council

Jindera and Pioneer streets diversion drain works

Four Mile Creek is the main waterway through Jindera, it has a series of tributary waterways which discharge into it. These tributary waterways include the Watson Street Drain, Pioneer Drive Drain, Molkentin Middle and Molkentin East waterways and they generally have limited incised channel capacity. In large floods, there is consequently substantial out of channel flooding.

This project will complete the investigation and design of potential diversion drainage works at Jindera and Pioneer streets (west of Jindera), that may divert floodwater and eliminate future flood damage to properties and businesses in the township.

Walla Walla Queen Street waterway catchment diversion drain

This project will construct a diversion channel, with small levee banks, along a privately-owned airstrip to direct stormwater flow to the east of Walla Walla. The drain will run east along the airstrip discharging stormwater to a culvert under Morgans Road, Railway and Chinatown Lane. This diversion will help reduce flooding along Queen, Railway, Commercial and Market streets in Walla Walla.

The Kensington Centennial Park floodplain management study and plan identified the need for a feasibility study on upgrading the culverts under Gardeners Road. The goal of this project is to determine the feasibility of increasing the pipe capacity under Gardeners Road to reduce the risk of flooding upstream of Gardeners Road.

Shellharbour City Council

Review of Elliot Lake – Little Lake floodplain risk management study and plan

Council will undertake the process of updating the design flood estimation techniques across the catchment. The Elliot Lake – Little Lake catchment has been selected, as there are very little major catchment and land use changes expected within this study area. Council will also take the opportunity to update the adopted flood model to incorporate additional overland flow paths that were not included in the previous study.

Sutherland Shire Council

Sutherland Shire overland flood study

Many parts of the Sutherland Shire are subject to overland flooding. Council has completed overland flood studies for high-risk catchments, however, Council has only a limited knowledge of overland flow behaviour and flood risk across the remainder of the Shire. Council will undertake a flood study using the latest flood modelling techniques to provide preliminary information on flood behaviour, hydraulic categories, flood hazard and flood risk for these areas.

Temora Shire Council

Temora floodplain risk management study and plan

This project will develop a floodplain risk management study and plan for the township of Temora. It will identify and assess a variety of flood risk management measures aimed at effectively managing the full range of flood risks. A floodplain risk management plan will then be developed that identifies a list of recommended floodplain management measures to implement over time.

Tenterfield Shire Council

Urbenville and Woodenbong flood study

Urbenville and Woodenbong currently do not have up-to-date flood information. This project will comprehensively map the flood behaviour of the area, using Lidar and providing detailed flood information to inform Council's planning departments and assist in ensuring future developments adequately consider flood risk.

Tweed Shire Council

Detailed design of Murwillumbah central business district levee spillway

During the March 2017 flood, the earthen section of the Murwillumbah central business district levee was overtopped in a few localised low points. The overtopping occurred in an unexpected location and in an uncontrolled nature. The Murwillumbah central business district levee and drainage study recommended the remediation of the levee low points and installation of a formalised spillway to achieve safe and controlled overtopping of the levee during events equal to or greater than the levee crest. This project will complete a detailed design for a spillway and levee rehabilitation.

Update and expansion of the Tweed Valley flood study

The current Tweed Valley flood study was completed in 2009 and covered only the more populated areas of the Tweed. Historical records and anecdotal evidence suggest that there are many more properties in the Tweed Shire's rural areas and villages that are exposed to flooding. This project proposes to expand the Tweed Valley flood study into the upper catchment to cover the villages of Chillingham, Tyalgum, Kunghur, Uki, Stokers Siding, Bilambil and the rural areas in between. Flood intelligence in these areas will allow Council to identify high-risk areas/properties.

Upper Hunter Shire Council

Review and update of the Aberdeen floodplain risk management study and plan

Upper Hunter Shire Council completed the Aberdeen floodplain risk management study and plan in 2015. At the time this plan was prepared, Council and the consultant were aware of discrepancies between the Aberdeen flood study and the Muswellbrook flood study. These discrepancies were not able to be resolved at that time and the risk management plan was prepared based on the modelling information provided in the Aberdeen flood study. Subsequent studies for the upgrade of the Aberdeen levee indicate that the design flood flows and levels in the earlier Aberdeen study are overestimated. This project will undertake a review of the flood modelling for Aberdeen.

Upper Lachlan Shire Council

Scoping study – 4 villages flood warning alert system

Council will undertake a scoping study for a total flood warning system to identify a range of options and to quantify the cost-benefits of each identified option. This project will determine the best option for a flood warning system for the 4 villages of Crookwell, Gunning, Collector and Taralga.

Albury City Council

South Albury levee upgrade – detailed design

The Albury City floodplain management study and plan recommended that a feasibility study of an upgrade of South Albury levee be undertaken. The feasibility study found that the existing levee does not provide protection against a 1% annual exceedance probability flood event, with overtopping found to occur, leading to inundation of an area of about 4.5 square kilometres.

This funding will allow Albury City Council to develop the concept designs and produce full detailed design documentation that can then be used to tender for the construction elements of the levee upgrade.

Bathurst Regional Council

Perthville flood mitigation works Stage 2 – construction of levee

Perthville flood mitigation stage two – construction of levee includes the construction of 1.3 kilometres of earthen and concrete levee, two stormwater pump stations and associated works. Completion of stage 2 will provide 1% average exceedance probability flood protection for 24 homes in Perthville.

Bega Valley Shire Council

Pambula River, Pambula Lake, Yowaka River flood study at Pambula and surrounds

Significant residential and commercial development pressure has arisen in the catchment and Council currently possesses no catchment-wide flood information. This project will undertake a flood study to define flood hazard and risks and will determine flood extents for a range of events, including the probable maximum flood/annual exceedance probability with a hydrodynamic ocean boundary condition.

Cabonne Council

Eugowra levee – construction to fill gap in existing levee

This project involves upgrading the existing town levee and construction of new sections of levee where gaps exist. Currently, the existing levee is inadequately sized and does not protect the community from flooding. There is an approximately 1 kilometre gap in the existing levee on Puzzle Flat Creek at Eugowra.

This project will complete the construction of the levee to protect Eugowra and ensure that flood water is retained within the channel of the creek and diverted around the village.

Carrathool Shire Council

Hillston Floodplain Risk Management Study and Plan

This project will develop a new two-dimensional flood model for Hillston following the completion of levee upgrades and then develop a floodplain risk management study and plan, to develop a list of floodplain management measures, planning controls and emergency response measures designed to lessen the impact of future floods in and around Hillston. This project will also consider the risks due to overland flow flooding as a result of the existence of the levee banks blocking local flows from entering the Lachlan River.

Clarence Valley Council

Bluff Bridge (Orara River) flood monitoring

This project will install a remotely monitored flood gauge in the Orara River at Bluff Bridge to enable residents to be aware of when the road is closed. Flooding of the Orara River has caused the Orara Way to close on many occasions at this location. The closure causes isolation and inconvenience to the community of Glenreagh and surrounds as well as through traffic between Grafton and Coffs Harbour.

Lower Clarence rural floodplain risk management study and plan

This project will prepare a rural floodplain risk management study and plan. In 2014, a report on the management of flood mitigation assets identified that the Council may be maintaining floodplain works that have little or no flood mitigation benefit or that perpetuate environmental harm. The report concluded that the best option was to prepare a new floodplain risk management plans for the rural floodplain.

Coonamble Shire Council

Stage four – Coonamble levee upgrade

This is the final stage of the upgrade of the levee for the protection of the township of Coonamble. This stage will undertake work on the eastern bank of the Castlereagh River from the Showground to Tooloon Street.

Cowra Shire Council

West Cowra detention basin and Waratah Street diversion pipeline investigation

This project will undertake a detailed investigation and design of works for the construction of a detention basin and pump out facility in the west Cowra drain catchment area and an associated diversion pipeline from Lyall Street to the Lachlan River. This project will reduce the risk of flooding for properties on Lyall Street, Walker Street and Hassan Street.

Dubbo Regional Council

Ballimore Village Flood Study and Flood Risk Management Study and Plan

The first stage of this project will involve a comprehensive flood study for Ballimore Village, it will incorporate data from the previous flood study, carried out in 1996, as well as other information and anecdotal evidence from local residents and Council staff. It is envisaged that the study will focus on the Talbragar River catchment as well as exploring the potential influence of local inflows. The results of the flood study will be used to formulate a floodplain risk management study and plan for the village.

Fairfield City Council

Fairfield golf course detention basin upgrade construction

This project will carry out upgrade works for the Fairfield golf course detention basin. The basin is located along Smithfield Road and immediately upstream of Mary MacKillop College. The upgrade will increase the basin capacity to 100-year average recurrence index, improve the basin embankment to satisfy the NSW Dams Safety Committee and lower/minimise the risk of embankment failure. This upgrade is part of the proposed combined upgrade of the Fairfield golf course and Mimosa Road detention basins. The proposed combined basin upgrade provides significant benefit to the residents not just immediately downstream of the golf course detention basin but also surrounding and downstream of the Mimosa Road detention basin.

Prospect Creek/Georges River flood study update and detention basin assessment

This project will review the Prospect Creek and Georges River flood studies using current modelling techniques and updated flood results for these areas. It will also undertake basin safety assessment and basin classification of detention basins in Hassall Street and Rosford Reserve with respect to the Dam Safety Committee's requirements.

Greater Hume Shire Council

Culcairn lowering stock route and stopping Billabong Creek flood affectation

This project will investigate lowering the stock route near the intersection with Balfour Street to allow local flows to pass and alleviate ponding upstream. Peak flood levels at flood-prone properties upstream of the stock route will be reduced by up to 0.3 metres. This project will also look at the feasibility of blocking the Billabong Creek anabranch at two locations.

Henty combined levee bank drainage works (investigate and design)

The proposed works to be investigated are located to the north of Henty and will protect existing homes that currently get inundated by stormwater during heavy rainfall. The inclusion of additional levees, into the existing combined levee system, is designed to prevent floodwaters from Buckargingah Creek flowing north and flooding residential properties in areas of the Olympic Highway of Grubben Road, Pleasant Hills Road and Angaston Street.

Holbrook Ten Mile Creek southern floodplain levee system

This project will investigate a levee option combining the Ten Mile Creek south levee with Caltex site protection to protect the Holbrook southern floodplain from Ten Mile Creek flooding, for events up to and including the one percent annual exceedance probability flood. A key feature of the option of this combined levee is that residents can evacuate during a Ten Mile Creek flood event, either via the Holbrook bypass on-ramp or via the Albury Street bridge.

Inner West Council

South Marrickville Flood Study

This study encompasses areas of the Inner West Council draining directly to the Cooks River, including parts of the suburbs of Marrickville and Dulwich Hill. This project will allow characterisation of flood behaviour and identification of flood affected properties within the area and will enable the introduction of planning controls.

Alexandra Canal Flood Risk Management Study and Plan

This floodplain risk management study and plan is the next step following completion of the Alexandra Canal flood study. This flood risk management study and plan will identify flood risk management options to address the risk to properties in the Inner West Council local government area of the Alexandra Canal catchment.

Johnstons Creek and Whites Creek Flood Risk Management Study and Plan

This floodplain risk management study and plan is the next step in the floodplain management process following completion of the Johnstons Creek and Whites Creek flood study. This flood risk management study and plan will identify flood risk management options to address the risk to properties in the Johnstons Creek and Whites Creek catchments, south of Parramatta Road.

Ku-ring-gai Council

Middle Harbour – southern catchments flood study

Steep terrain and ridge-top development have led to major flood risk within Ku-ring-gai, from flash flooding along headwater streams and drainage depressions. This project will develop a flood study, that will be used to undertake a flood risk management study and plan to guide future flood risk management actions.

Lake Macquarie City Council

Accounting for adaptation in Swansea and surrounds – cost-benefit distribution

The 2012 Lake Macquarie flood risk management plan identifies Swansea, Pelican and Blacksmiths as the most vulnerable communities to lake flooding and sea level rise. The plan identified 430 properties in the 3 suburbs currently experiencing over floor flooding in a 1% annual exceedance probability event; this number will rise with sea level rise.

This project will use the outcomes of the probabilistic hazard assessment on Pelican, Blacksmiths and Swansea as the basis of a more rigorous shortlisting, cost-benefit analysis and distribution analysis to assist Council and the community to complete the proposed local adaptation plan.

Flood study assessment for residual Lake Macquarie waterway tributary catchments

Lake Macquarie City Council has committed to undertaking and completing flood studies and flood risk management studies and plans for 37 catchments since the mid-1980s. To complete the program, there are now only 11 minor tributary catchments where a flood study has not been undertaken. This project will deliver a flood study for the remaining tributary catchments. The study will utilise appropriate hydraulic modelling and a history of past flooding to identify areas with flooding constraints.

Liverpool City Council

Liverpool overland flow path study for rural catchment areas – stage two

In 2006, Council completed a broad overland flow path study of the entire local government area to identify and prioritise sub-catchments that would be prone to overland flooding. Subsequently, the Council undertook a detailed overland flow path study for prioritised urban catchment areas. The rural catchment areas were not considered a priority at the time.

The precincts of Austral, Leppington North and East Leppington are the latest areas in the Liverpool local government area being developed. This development will transform the current rural landform into urban residential precincts.

This project will assist the Council with understanding the priority sub-catchments that have high flood risk and require detailed flood studies and flood risk management studies.

Lockhart Shire Council

Milbrulong Road drainage works

This project involves the construction of a drain from Milbrulong Road, south along the industrial park and South Common to the creek crossing of Albury Road. The drain will collect and remove water from east of the town that comes from the Milbrulong Road and discharge it into Brookong Creek, south and downstream of the town. The works involve 464 metres of drainage channel as well as enhancing culvert systems under Milbrulong Road, Oaklands Railway and Albury Road.

Maitland City Council

Feasibility and route selection study for a high-level evacuation route

Council will undertake a detailed feasibility and route selection study for the construction of a high-level evacuation route, to provide evacuation for central Maitland and Lorn. This will improve evacuation during larger floods.

Moree Plains Shire Council

Improvement to flood warning data at Mungindi

This project will install a telemetry system which collects river height information, to maximise response times and improve the accuracy of information to community members and emergency services. This information will be used to provide reliable information to evacuate affected families and stock from high-risk areas.

Mungindi levee investigation and design

The Mungindi community is regularly inundated by flood events which isolate the town. The current levee is at approximately the 1% annual exceedance probability height, this may need to be increased by a minimum of 1 metre to provide a level of protection recommended by the Floodplain Development Manual.

This project will investigate the upgrade required and design and cost of the upgrade works.

Murrumbidgee Council

Darlington Point floodplain risk management study and plan

This project will complete a floodplain risk management study and draft plan for Darlington Point. South Darlington Point is protected by a levee, but North Darlington Point and the wider floodplain remain exposed to regular flooding from the Murrumbidgee River. This project will investigate floodplain management options to address the residual flood risks and develop a plan of measures for future implementation.

Narrabri Shire Council

Boggabri floodplain study

Narrabri Shire Council will undertake a flood study for the township of Boggabri. The latest flood information held by the Council is an aerial photograph depicting flood levels in July 1998, which is insufficient in relation to managing flood risk and providing information to the Boggabri community. The information gathered in this project will be used to develop and subsequently implement plans and actions aimed at minimising the impacts of flooding.

Narrandera Shire Council

Barellan levee – feasibility study

This project involves the examination of the various conceptual levee options developed for Barellan, to determine a final option to progress to detailed design. There were several levee alignment options identified and assessed in the Barellan flood risk management study, this project intends to perform a detailed assessment of each of the options and to determine the option that is most feasible.

Narromine Shire Council

Narromine town floodplain risk management plan update

This project will review the floodplain risk management study plan for Narromine, to include information from flood events that have occurred in recent years.

Northern Beaches Council

Collaroy Flood Study

The Collaroy floodplain is a coastal floodplain flanked along its western boundary by a steep escarpment. Three creeks flow eastwards, the largest being Collaroy Creek, which flows through Anzac Avenue Reserve towards the southern end of Collaroy Beach. Numerous properties are at risk of flooding, with some already known to have experienced severe flooding.

This project will deliver the first flood study ever to be undertaken in the Collaroy Beach catchment. It will investigate the extent and severity of flooding, map the overland flow paths and identify flood-prone properties. The flood information will help Council to plan for the area to minimise flood risk.

Middle Harbour Flood Study

This project will investigate the extent and severity of overland flooding in the western part of the Northern Beaches Council area. Most of the area has never been investigated for flooding, and this study will map the overland flow paths and identify flood-prone properties to enable planning controls to be introduced.

Edward River Council

North Deniliquin levee upgrade – stage 1 investigation and design

The existing North Deniliquin levee does not protect against a 1% annual exceedance probability flood, as it has a relatively small design freeboard of 0.1 metres for most of its length. In addition, the curvature of the Edward River means that a higher flood level upstream of Brick Kiln Creek will occur in given design events. The current levee will overtop at 3 locations in a 2% annual exceedance probability event and at 6 locations in a 1% annual exceedance probability flood event.

This project will undertake a feasibility analysis and develop a design to raise the North Deniliquin levee to a level of protection equivalent to that of the South Deniliquin levee, 1% plus 0.5 metres is proposed to address the vulnerability for North Deniliquin.

Fairfield City Council

King Park detention basin upgrade investigation and design

The Three Tributaries floodplain risk management study and plan project identified the safety and performance of the King Park detention basin, as an issue. Specifically, the King Park basin will overtop and potentially fail in floods above the 100-year annual recurrence index event, with significant risk to people and property downstream. This project will investigate the feasibility of increasing the basins capacity and prepare detailed designs for this, so that the basin performs safely in floods.

Stockdale detention basin upgrade investigation and detailed design

The Stockdale basin will overtop and potentially fail in floods above and including the 20-year average recurrence interval event, posing risk to people and properties downstream.

Tweed Shire Council

South Murwillumbah voluntary purchase scheme

A voluntary purchase scheme is in place for high hazard flood affected homes along the Tweed River frontage of River Street, South Murwillumbah. The existing earthen levee provides limited low level protection from small flood events. Properties have been purchased in the region over the past twenty years. Only a few eligible properties remain, and it is difficult to predict when these will be purchased, given the voluntary nature of the program and the owner's willingness to sell their property. Once removed, the properties will become public open space to be enjoyed by the wider Tweed community.

Upper Hunter Shire Council

Aberdeen flood warning system

The development of a flood warning system for Aberdeen has been identified as an immediate priority in the Aberdeen floodplain risk management plan due to the magnitude of flood evacuation issues that exist and the rapid rate of rise of the Hunter River at this location. There is no warning system currently in place.

The Aberdeen floodplain risk management study has identified that up to 250 people may require evacuation during a major flood event. Significant numbers of dwellings located behind the levee have escape routes that are cut off by high hazard flooding in a five percent annual exceedance probability event. These dwellings suffer over floor flooding in a one percent annual exceedance probability event.

The proposed flood warning system will provide the State Emergency Service with more timely and accurate information to predict flood levels and issue flood warnings and enable the timely implementation of local emergency management measures including evacuations.

Bankstown City Council

Continuation of Milperra Voluntary Purchase Scheme: Stage 4

The Bankstown Voluntary Purchase Scheme originated from the Moorebank–Milperra Floodway Study. The study identified the area on the Bankstown side of the Georges River, downstream of the Milperra Bridge, as an extremely hazardous area and recommended Voluntary Purchase as the only flood management strategy for the area. A total of 25 properties were included in the scheme and Council has successfully purchased 21 of these. Stage four will focus on acquiring the remaining properties when available.

Bathurst Regional Council

Kelso Voluntary Purchase

The Kelso Voluntary Purchase scheme identified nearly 100 residential properties on the Kelso floodplain which were at high risk of flooding. Council has purchased and demolished a significant number of these properties. This project will continue purchasing the remaining properties if they become available.

Bathurst Flood Mitigation – Construction of Perthville Levee

Perthville Town levee is the final stage of the Bathurst Flood Mitigation project. Since 1999, implementation of actions in the Bathurst and Perthville Floodplain Management Plan has seen the construction of approximately 10 kilometres of earthen and concrete levees at a cost of around $12 million.

Blue Mountains City Council

Wattlecliffe Levee Wall

According to the Lapstone, South Glenbrook and South Blaxland Floodplain Risk Management Study and Plan, properties within the Wattlecliffe Estate will be impacted by 1% Annual Exceedance Probability Flood (AEP) flood events. The Wattlecliffe Estate is in a high hazard area with flood depth up to 0.5 metres. A low wall will be constructed on the footpath between the Great Western Highway, Acacia Place and Wattlecliffe Drive, Blaxland to divert the 1% AEP overland flow into the exiting pit inlet.

Cessnock City Council

Swamp Creek flood mitigation works – environmental investigation and design

This project represents the first stage in the implementation of vegetation clearing works along Swamp Creek at Abermain and Weston. Recent investigations, as part of the floodplain risk management study and plan, shows that this will have significant benefit in reducing flood levels and flood damage in these townships. The work will include ecological and geotechnical investigations to identify the potential environmental impacts of the proposed works, and will also involve further design to prioritise the vegetation clearing activities.

Wollombi Flood Warning System – Investigation and Design, Stage 4

This project will implement recommendations from the Floodplain Risk Management Plan (FRMP) by further investigating a potential ‘Flood Warning System’ in association with the Bureau of Meteorology and State Emergency Services (SES). It will include the options for flood warning enhancement, including appropriate gauge/reporting locations, integration into existing flood warning systems, installation, operating costs, ownership, management and maintenance requirements, liability, and responsibility. The study will identify opportunities to improve emergency management to assist the SES and Rural Fire Service commands covering this area of the Wollombi Village and surrounds.

Coonamble Shire Council

Coonamble levee upgrade: Stage 2

Previous studies have identified that the upgrade of the levee is a high priority for the protection of the town. Council has split the upgrade into workable stages to ensure the successful completion of the project. Stage 1 of the levee is already complete and has upgraded 2000 metres of levee. This stage will upgrade from 400 metres north of King Street to the Coonamble Hospital and from Taloon Street to Macquarie Street.

The project will involve completion of detailed investigation and design work for the construction of a detention basin and pump out facility in the West Cowra drain catchment area and an associated diversion pipeline from Lyall Street to Waratah Street. This project will reduce the risk of flooding for properties on Lyall Street, Walker Street and Hassan Street.

Dungog Shire Council

Voluntary purchase as part of Floodway Clearance Program

Dungog experienced a significant flood in April 2015 which resulted in four houses being washed away, one dwelling being moved off its foundations and significant over floor flooding in a number of properties. This funding will enable council to consider purchase of properties impacted by the floods.

Flood Risk Management Study and Plan for Dungog

This project will review the existing Williams River Study and extend this study to provide more detailed analysis of the Myall Creek and local catchments. Flood data from the April 2015 event is to be reviewed and used to validate the existing and revised model. A floodplain risk management study and plan will be prepared based on the updated study to provide proposals for managing and reducing the existing flood risk to Dungog residents.

Fairfield City Council

Fairfield Golf Course detention basin upgrade and design

The Three Tributaries Floodplain Risk Management Study and Plan project identified the safety and performance of Council&rlsquo;s flood detention basins, including the Fairfield Golf Course basin, as an issue. The Fairfield Golf Course basin will potentially fail in floods above the 50 average recurrence interval. This project will investigate increasing the basin embankment and spillway upgrades to safely perform in the full range of flood events and prepare detailed designs for the preferred option

Mimosa Road detention basin upgrade investigation and design

The Three Tributaries Floodplain Risk Management Study and Plan project has identified the safety and performance of Council's flood detention basins, including the Mimosa Road basin, as an issue. The Mimosa Road basin will potentially flood and overtop in floods above 20-year average recurrence interval. This project will investigate increasing the basin embankment and spillway upgrades to safely perform in the full range of flood events and prepare detailed designs for the preferred option.

Gosford City Council

Davistown and Empire Bay Floodplain Risk Management Study and Plan

Previous studies have identified that the upgrade of the levee is a high priority for the protection of the town. Council has split the upgrade into workable stages to ensure the successful completion of the project. Stage 1 of the levee is already complete and has upgraded 2000 metres of levee. This stage will upgrade from 400 metres north of King Street to the Coonamble Hospital and from Taloon Street to Macquarie Street.

Gosford voluntary purchase – Erina

The review of the Erina Creek Floodplain Risk Management Study and Plan recommends voluntary purchase and demolition of four properties located in Erina. The aim is to eliminate risk to life and continuous property damage by offering voluntary purchase to eligible owners.

Gosford voluntary purchase – Pearl Beach: Stage 1

The Green Point Creek, Pearl Beach Flood Study identified a property that would be suitable for purchase to mitigate risk of harm to life. The property in Crystal Avenue is the only principal dwelling built within the floodplain of Green Point Creek.

Woy Woy Floodplain Risk Management Study and Plan

The Woy Woy Peninsula is prone to flooding, especially during long-duration rain events. Flooding occurs both in road reserves and on numerous residential properties throughout the peninsula.

A flood study was completed in 2010 as the first stage of the floodplain risk management process. The flood study determined the nature and extent of flooding. A floodplain risk management study and plan is now required to progress the floodplain risk management process and identify and investigate various options to manage the identified flood risks in the flood prone areas of the Woy Woy Peninsula. This will determine action that should mitigate, or at least, reduce the impact of future flood events.

Gundagai Shire Council

Gundagai Floodplain Risk Management Study and Plan

This project represents the next stage in the Floodplain Risk Management Process with the development of a Floodplain Risk Management Study and Plan for Gundagai. The Flood Study has been completed which has identified significant flooding risks for the town of Gundagai.

The Levee Bank at Darlington Point in its current condition may pose a threat to property and the community if it fails. This project will undertake flood studies to provide a better understanding of the flood behaviour and associated risks to inform future management and alterations to the levee.

Darlington Point Floodplain Management – reconstruction of levees (Areas 3–5A)

Council recently completed a flood study for the Blackbutt Creek Catchment. The study confirmed that the Blackbutt Creek catchment is one of Ku-ring-gai's most significantly flood affected areas where steep terrain and ridge-top development has led to major flood risk arising from flash flooding along headwater streams and drainage depressions. The Flood Risk Management Study and Plan will examine appropriate management actions with the aim of reducing flooding risk for current and future development.

Narrabri Shire Council

Wee Waa Levee Risk Management Study and Plan

Wee Waa is situated on the Namoi River floodplain near the confluence of the Namoi River and the Wee Waa Lagoon. The town has a population of approximately 1700 and is situated in the middle of the Namoi River floodplain. During large flood events, floodwaters spread out over the floodplain, reaching significant depths and affecting large areas of agricultural land. The majority of Wee Waa’s residential, commercial and industrial properties are protected by an existing earthen levee that surrounds the town. Council recently received a report into the effectiveness of the Wee Waa Levee to withstand the regular flooding experienced in the lower Namoi River Valley. The study has identified that the levee does not protect the town from a one percent Annual Exceedance Probability (AEP) flood with sections of it being overtopped. Council will prepare a Flood Plain Risk Management Study and Plan to assist in determining the most effective means of protecting the town.

Newcastle City Council

Wallsend Commercial Area Flood Risk Management Plan – Detailed Design

The risk of flooding in the Wallsend commercial area is significant and in the June 2007 event inundation depths of up to 2 metres was experienced in shops and commercial buildings. A floodplain risk management plan (FRMP) was prepared in 2009 to outline a strategy to reduce flood risk in the commercial area. The recommended strategy proved to be expensive requiring a substantial amount of funding to reduce the risk of flood. The Draft Wallsend Central Business District Floodplain Risk Management Plan – implementation Study of 2015 was prepared to investigate more cost-effective solutions to flooding based on the findings of the 2009 FRMP. The implementation study identified a number of targeted options to reduce flood risk for the commercial area of Wallsend with a positive cost benefit ratio. A preferred option has been selected in consultation with stakeholders and the community. The preferred option involves the removal of the Tyrrel and Boscawen Street bridges and modification of the Nelson Street Bridge to improve conveyance of flood water in the open channel. During the June 2007 event these bridges were subject to near complete blockage and flows surcharged into adjacent areas as a result. Detailed design of the preferred option will allow for a better understanding of the costs and construction requirements associated with the preferred option.

Orange City Council

Wagga Wagga City Council

Wagga Wagga Main City & North Wagga Levee Construction: Stage 1

This project represents the first stage of construction in the upgrade of the Wagga Wagga levee protection system, encompassing the Main City Levee, to provide appropriate levels of protection. Currently, the Main City Levee does not provide protection against the 1% annual exceedance probability design flood event in the Murrumbidgee River which places the Wagga Community at risk in the event that a flood of this magnitude occurs. Within this Stage 1 project, construction of the first section of the Main City levee (about 2.1 kilometres), will be completed to provide a 1% annual exceedance probability design flood level of protection (with freeboard) within this section.

Wagga Wagga Major Overland Flow Flood Risk Management Study and Plan: Stage 2

The project will provide appropriate planning controls and flood mitigation measures for overland flooding in the urban and adjoining areas of Wagga Wagga. The study will break the area into four catchments, being the North Wagga Hydraulic Extent, the East Wagga Hydraulic Extent, the Lake Albert Hydraulic Extent and Wagga City Hydraulic Extent, looking at inundation areas and velocity/depth values across the catchments. The project will:

• look at floor levels
• examine damage potential
• look at a variety of flood mitigation options
• make relevant recommendations
• investigate failure implications of Crooked Creek levee
• investigate risk to life of other areas in terms of the 1% annual exceedance probability and probable maximum flood flooding, and define the flood planning area for all 4 areas.

Weddin Shire Council

Emu Creek Stream Management Plan Implementation

The implementation of the Emu Creek Stream Management Plan involves the removal of sediment and dumped fill, removal of vegetation obstructing flows, plantings for bank stabilisation, improvements for fence crossings, construction to stabilise erosion and weed management. Priority locations have been identified for each of these activities throughout Emu Creek and its tributaries. This project will complete these works in the priority locations, monitor their success and continue to manage the impacts over three years. These works will mitigate flooding impacts and improve environmental outcomes within the Emu Creek catchment and its tributaries around Grenfell.

Wollongong City Council

Allans Creek Voluntary Purchase Scheme

Over past decades, Allans Creek and its tributaries have experienced significant flood events, which have caused property damage and posed a high hazard to the residents living in close proximity to the major drainage channels in the area. This project will purchase several properties located along the riverbank at Arrow Avenue, Figtree. This program will provide funding if the opportunity exists to purchase the identified properties.

This is an ongoing voluntary purchase project for Towradgi Creek. This program will provide funding if the opportunity exists to purchase the identified properties.

Young Shire Council

Young Stormwater Upgrade Scheme Concept Design Study: Stage 3

Young Shire Council have recently completed their Floodplain Risk Management Study and Plan. This plan identified the need for a concept design study as one of its highest priority actions in order to upgrade the stormwater system and reduce the risk of flooding in Young. In recent years, residential and commercial properties in Young have experienced damage as a result of flooding. The design will provide Council with a cost estimate in order to determine a priority listing for future construction works. The future works will alleviate existing flooding issues and provide for future development within the town. In combination with appropriate planning controls, the stormwater upgrades to be considered in the design will reduce the risk of future flood damage.

Funding for these projects came from 2 programs: the NSW Government Floodplain Management Program (FMP) and the Floodplain Risk Management Grants Scheme (FRMGS), which was jointly funded by the NSW Office of Emergency Management and the Australian Government.

Eurobodalla Shire Council

Flood prone access to Moruya Hospital – raising Murray Street Moruya

The project is the provision of additional culverts under Murray Street either side of the existing culvert and the raising of the surface level of the road. These works will increase the availability of access across Gundary Creek by reducing the number of instances when the road is inundated.

Murray Street is the highest crossing of Gundary Creek and is the last access to the Moruya Hospital during a flood event. The need for raising Murray Street to reduce the loss of access to Moruya Hospital was identified in the Moruya Floodplain Risk Management Plan and is the only outstanding work of that plan.

The project will, by increasing the flow area under the road and raising the level of the road, decrease the number of events that will prevent access to Moruya Hospital.

Reedy Creek Voluntary Purchase Scheme

The Reedy Creek Flood Study identified a number of properties as being inundated by the five per cent Annual Exceedance Probability event. A number of options were investigated and the Voluntary Purchase Scheme was determined as the most appropriate method of management. The available options were considered in the Reedy Creek Floodplain Risk Management Study and the voluntary purchase of nominated dwellings was identified as the highest priority.

Discussions have been held with the owners, with preliminary agreement being reached subject to a number of conditions. It is proposed to purchase one dwelling in the 2014/15 year and undertake earthworks on the property in 2015/16.

Fairfield City Council

Liverpool City Council

Brickmakers Creek Channel improvement works – Elizabeth Street to Campbell Street

Brickmakers Creek is a tributary of Cabramatta Creek, which flows through the suburbs of Casula, Lurnea and Liverpool to meet Cabramatta Creek in Warwick Farm and subsequently Georges River. Flood studies undertaken in 1998 and 2004 have identified Brickmakers Creek as the primary cause of major flooding of parts of the northern Liverpool Central Business District (CBD), even in smaller storm events. The flooding extends to the major state arterials comprising of the Hume and Cumberland highways causing major traffic delays into and out of Liverpool and surrounding areas and the residential areas located adjoining the Hume Highway in the northern parts of the CBD.

The Floodplain Risk Management Plan adopted for Brickmakers Creek recommended a range of mitigation works. Among other flood mitigation works, the study recommended channel improvement works between Elizabeth Street and Orange Grove Road and construction of a detention basin at Amalfi Park to significantly attenuate flows and reduce flooding within the entire creek corridor and the northern CBD area.

Under stage one of flood mitigation works, channel improvement between Campbell Street and Orange Grove Road was completed in 2011 under funding assistance from Natural Disaster Mitigation Program. The work has shown immediate effect on parts of the area by relieving flooding of properties and roads which were previously affected from frequent storm events.

Council completed detailed design of Amalfi Park detention basin. Funding for basin construction has been approved under the State Government Floodplain Management Program and construction works have commenced.

This current project constitutes stage two of channel improvement works and will involve investigation and design of channel improvement work for the remaining channel section from Elizabeth Street to Campbell Street. Subsequent completion of proposed improvement works would further reduce flooding risks along Brickmakers Creek.

Georges River Flood Study

The Georges River catchment is one of the most populated catchments in Australia, located within the Sydney basin with a catchment area of approximately 930 square kilometres. The river traverses through a number of local government areas, including Liverpool, Fairfield, Bankstown and Sutherland local government authorities. The river and its tributary creeks represent Sydney's most immediate flooding problems, both in terms of the number of properties affected by flooding and the potential for increased flood damage due to development pressure within the catchment.

The Georges River Flood Study was undertaken in 1991 and design flood levels have been established from the results of a physical model constructed during 1980s by the Public Works Department. In 2004, the Georges River Floodplain Risk Management Study and Plan (FRMP) was prepared and adopted by all participating councils. As part of the FRMP a MIKE11 hydraulic model was developed.

Liverpool City is a regional city of South Western Sydney and is undergoing significant development and population growth. Accordingly, significant changes have occurred within the catchment in terms of landform and land use changes including filling and development within flood prone areas. These changes could potentially impact on flood behaviour and flood extent mapping.

In view of significant changes in landform and land use within the catchment since the original flood study was undertaken in 1991, Council proposes to undertake a review of the flood study for the Georges River. The proposed study will be undertaken using the most up to date ground survey data captured by Aerial Laser Scanning within Liverpool and a two-dimensional hydrodynamic model. The model would provide Council with a tool enabling strategic assessment of the impacts of developments and risk management options for existing and future developments within the catchment.

Liverpool Central Business District overland flow path mapping

In 2005, Council undertook the Liverpool Central Business District (CBD) Floodplain Risk Management Study. The study assessed drainage capacity of existing pipe systems and identified major deficiencies in drainage capacities. Major trunk drainage upgrading works were recommended to alleviate flooding problems within the city centre.

Liverpool (CBD) trunk drainage works is an approved ongoing project under the NSW Government's Floodplain Management Program. Significant parts of the project have been completed using grant funding assistance under the State Floodplain Management Program. It is expected that the final and remaining stage of trunk drainage works will be completed in 2014–15.

The Liverpool Floodplain Management Study 2005 has assessed overland flooding and pipe drainage network performance using DRAINS hydraulic/hydrologic model. DRAINS model generates flood depths and velocities of overland flows at locations of overflow pits in the network in a tabular format. Due to modelling limitations, the DRAINS model does not generate flood inundation maps and flood level contour maps.

The NSW Floodplain Development Manual requires reviewing of flood studies and updating of flood maps to reflect changes in the catchments over the period since the flood study was undertaken. Since the flood study for the area was undertaken in 2005 significant changes have occurred within the catchment including construction of major trunk drainage works. For better understanding of flooding behaviour within the CBD area Council needs to update the flood study and develop flood risk maps. The proposed study will involve detailed hydrologic and hydraulic modelling of the CBD stormwater drainage system using two-dimensional hydraulic model and will prepare flood inundation maps including flood levels contours, flood hazard and flood risk maps. The modelling will enable Council to evaluate the effect of the completed trunk drainage system and will provide new tools for floodplain management.

Liverpool Central Business District trunk drainage works – Elizabeth Street, George to College Street

Council’s stormwater drainage system within the city centre is over capacity and has been the cause of frequent flooding within parts of the city. In order to mitigate the adverse impact of flooding Council undertook a detailed flood study for the city centre and developed Liverpool Central Business District (CBD) Floodplain Management Plan in 2005. The Plan recommended construction of large diameter trunk drainage pipes to significantly increase pipe system capacities to alleviate flooding of the CBD area.

Liverpool CBD trunk drainage works is an approved ongoing project. Significant parts of the project have already been completed using grant funding under the NSW Governments Floodplain Management Program.

Council commenced a staged construction program in July 2007 to provide a major underground drainage system and to date over 1.24 kilometres of pipelines have been constructed using both open cut and tunnel boring techniques. Works completed so far include installation of larger diameter pipes along College, Moore, George and Scott Streets, construction of a gross pollutant trap and construction of a major outfall structure on the western bank of the Georges River.

Council has recently completed the second last remaining part of the trunk drainage system along Scott and George streets under the State Floodplain Management Program.

Detailed design of the last remaining part of CBD trunk drainage works along Elizabeth Street is completed and the construction works are scheduled to commence in 2014–15.

Review of Liverpool Overland Flow Path Study

Parts of Liverpool local government area (LGA) are subject to flooding from both mainstream and overland flooding. To manage occupation of flood prone lands, Council adopted a floodplain risk management policy to reduce impacts of flooding on properties and minimise damages from floods.

In 2006, Council completed a broad overland flow path study (overview study) of the entire LGA to identify and prioritise sub-catchments that would be prone to overland flooding. Council undertook detailed overland flow path studies of five of the largest and highest prioritised urban sub-catchment areas over the past few years. The detailed studies investigated overland flooding behaviour in further detail, and prepared flood inundation and flood risk mapping. Subsequently, Council undertook an overland flood risk management study for these areas which is now nearing completion.

During detailed overland flood studies, issues with catchment prioritisation in the overview study for a number of prioritised sub-catchments (for future detailed study) were identified. It was found that there are no overland flooding issues in some of the high priority sub-catchment areas identified by the overview study. However, overland flooding issues were identified in areas which were not identified in priority areas of the overview study. The discrepancy appears to be due to deficiency in the modelling methodology used in the overview study. It has become necessary to review the overland flow path study with finer modelling resolution to identify priority sub-catchments of the remaining urban areas before undertaking detailed overland flow path studies of those areas.

The proposed overland flow path study will involve undertaking an overland flow path study of the remaining Liverpool urban areas (i.e. excluding five sub-catchment areas completed under the detailed studies) with two-dimensional modelling with finer resolution. The study will identify overland flow paths within the study area and prioritise local sub-catchments for further detailed studies.

Lockhart Shire Council

Lockhart flood mitigation works detailed design: Stage 3

Stage 3 works will produce detailed design plans to further reduce flood risk in Lockhart. This two part mitigation scheme will significantly reduce flood risk and associated damages throughout Lockhart. The Lockhart Government Dam Upgrade will reduce flooding in regions north of Green Street whilst the Brookong Street Drain will provide mitigation for regions between Green Street and Brookong Street.

Lockhart Voluntary Purchase Feasibility Study: Stage 3

In Lockhart 16 residences have been identified as being within the Brookong Creek floodway and in high hazard areas as defined by the Lockhart Flood Risk Management Study and Plan. During the recent 2010 and 2012 floods a number of residents that reside in these homes were evacuated by the NSW State Emergency Service. Homes situated in the floodway of Brookong Creek are exposed to considerable flood risk from the one per cent Annual Exceedance Probability event.

The Lockhart Flood Risk Management Study and Plan has recommended that a feasibility assessment be undertaken to determine community support of a voluntary purchase scheme.

The Rock (East) Flood Mitigation Scheme detailed design: Stage 3

These Stage 3 works will produce detailed design plans to further overall work to reduce flood risk in The Rock.

This 2-part mitigation scheme comprising investigation and design funds are sought for will significantly reduce flood risk and associated damages throughout The Rock. Drain upgrades will improve transfer of water from Flowerpot Hill to Burkes Creek including by undertaking upgrades of Olympic Highway culverts as well as adding new drains and cleaning out of existing ones.

Twenty-six fewer lots will be flooded with 15 fewer properties flooded over floor in the one percent Annual Exceedance Probability event with implementation of the scheme and an average annual saving to the community of $71,400 per year is expected. Flood levels will be lower both upstream and downstream of the Olympic Highway and railway line.

The Rock (West) Flood Mitigation Scheme detailed design: Stage 3

This 4-part scheme is designed to reduce flooding in The Rock West. The scheme starts with a drain along Emily Street which conveys flow into the Nicholas Street basin. Flow is then transferred into a drain that travels along Yerong and then Urana streets before passing through the upgraded Urana Street culverts.

The Rock Voluntary Purchase Feasibility Study: Stage 3

At The Rock, three residences have been identified as being within the Burkes Creek floodway and in high hazards areas as defined by The Rock Flood Risk Management Study and Plan. During the recent 2010 and 2012 floods residents living in these homes were evacuated by the NSW State Emergency Service. Homes situated in the floodway of Burkes Creek are exposed to considerable flood risk from the one per cent Annual Exceedance Probability event.

The Rock Flood Risk Management Study and Plan has recommended that a feasibility assessment be undertaken to determine community support of a voluntary purchase scheme.

Marrickville Council

Alexandra Canal Flood Study

Alexandra Canal drains the suburbs of St Peters, Tempe and Sydenham. Marrickville Council strongly acknowledge the need to map flood prone properties within the Alexandra canal catchment and to introduce planning controls to protect people and property from future flood damage.

As the areas are undergoing redevelopment there is a need for flood maps to establish minimum floor levels and the prohibition of structures in floodways.

Johnstons Creek Flood Study

Johnstons Canal drains the suburbs of Petersham and Camperdown into Rozelle Bay. Marrickville Council strongly acknowledges the need to map flood prone properties within its portion of the Johnstons Canal catchment and to introduce planning controls to protect people and property from future flood damage. As the areas are undergoing redevelopment there is a need for flood maps to establish minimum floor levels and the prohibition of structures in floodways.

Murrumbidgee Shire Council

Darlington Point floodplain management – reconstruction of levees areas 3 – 5A

The levee bank at Darlington Point in its current condition poses a threat to property and community. The industry standard is to have a levee system that caters for a one in a hundred year flood. Darlington Point Levee is up to 0.5 metres short of this height. In addition the Darlington Point levee was constructed in haste to protect the town from previous flood events. This resulted in a lack of engineering design in the construction process. It was observed in the 2012 flood event that water was penetrating the existing levee structure and, while it did not fail in this instance, there were concerns it may have. This led to evacuation orders being issued for moderate floods at the cost to the government of over one million dollars per flood event.

This project aims to upgrade the levee system, engineered to protect the township from a one in a hundred year flood event. This will in effect reduce the frequency at which costly and stressful evacuations of Darlington Point will be required.

Muswellbrook Shire Council

This study will also assist in developing emergency management plans and assist Council in managing future development in the town.

Newcastle City Council

Newcastle city-wide flood warning singnage

The Newcastle City-wide Floodplain Risk Management Study and Plan (2012) Action Wa.3 calls for the installation of passive and active road signage to relay warnings, advise of flooded roads and provide other emergency information. This project will deliver this action entailing consultation with relevant stakeholders, documentation of roles and responsibilities, a review of existing flood warning infrastructure, identification of prioritised costed opportunities to add to or enhance such infrastructure (such as electronic billboards) and community education.

Scoping study Morgan Selwyn floodway Merewether Heights

The Newcastle City-wide Floodplain Risk Management Study and Plan (the Plan) (2012) indicates that during the one per cent Annual Exceedance Probability, several properties lie wholly or partly within the floodway. These properties remain in private ownership. Action Priority 3 of the Plan is to investigate voluntary purchase of one or more properties within the Morgan–Selwyn floodway. This scoping study is intended to form the basis for this action by investigating flood levels and extent, and hydraulic and hazard categories, under different scenarios of building removal and/or velocity controls using numerical and/or physical models. In doing this it will evaluate the benefits of removing one or more existing buildings from within the floodway ensuring that, if and when a dwelling or structure is removed, risks to flooding are not exacerbated to other properties and will prioritise acquisition, demolition or other measures to improve the floodway.

Palerang City Council

Braidwood Floodplain Risk Management Study and Plan

The Braidwood Floodplain Risk Management Study and Plan will assess structural and non-structural works to mitigate or remove flood risk for the town of Braidwood. It will involve hydraulic and hydrologic modelling to determine the existing flooding issues and recommend suitable works and/or controls to protect residential dwellings and community facilities from future flooding.

Parramatta City Council

Parramatta River Catchment Mainstream Flood Study

The Parramatta River is the major river passing through the Parramatta Council area, before it reaches Sydney Harbour. It passes thousands of homes and businesses, including those in the Westmead Biomedical Precinct and the Parramatta central business district (CBD), which is Australia's 6th largest CBD. Parramatta Council is developing a Floodplain Risk Management Plan for the river, which will look at methods to manage flooding in the Parramatta area, and reduce the social, economic and environmental effects of future floods.

Council has completed the first stage of developing the Plan, a literature survey, and is now moving onto creating a single, unified flood model for the Parramatta River catchment in the Parramatta Council area. The new flood model will enable options for reducing flooding to be considered and will also help determine which areas are likely to be affected by flooding after very heavy rain.

The information will inform potential purchasers of the risks associated with individual houses in the rural area and at the same time give emergency response agencies good information on where resources should be deployed in a flood.

Flood evacuation South Lismore

This project will examine the option for constructing a new high level escape route to high ground for South Lismore.

Ryde City Council

Waterloo Park detention basin construction

The City of Ryde experienced several large storm events in 1984, 1986, 1988 (twice), 1989 (twice) and 1990 which caused wide spread flooding. Since that period rainfall events in May 1998 and April 2003 caused significant problems.

A flood study and floodplain risk management study and plan determined the nature and extent of flooding in the subject area. The area is subject to high risk. The construction of the Waterloo Park detention basin will reduce the risk of flooding of many properties at Libya Place and Waterloo Road. It will also reduce the risk of loss of life or injury to residents. The Waterloo Park detention basin makes use of the open space owned by the Council.

Powells Creek is a small tributary of the Parramatta River, and Saleyards Creek is the major tributary of Powell Creek. The total catchment area of Powells Creek to Homebush Bay Drive is 8.1 square kilometres and Saleyards Creek to the confluence with Powells Creek is 3.2 square kilometres. Saleyards Creek is within the Strathfield Council area and Powells Creek is within the Strathfield, Burwood and Canada Bay council areas. Council completed Powells Creek and Saleyards Creek Flood Study in 1998 using a one-dimensional model and limited ground survey. The study provided information on overland flooding along the major pipe system only.

In 2010 Council completed the Cooks River and Coxs Creek Flood Study using a 2-dimensional model and aerial laser scanning (ALS) data and obtained comprehensive information on overland and mainstream flooding in the catchments.

Strathfield Council has decided to review its flood study for Powells Creek and Saleyards Creek catchments using 1-dimensional/2-dimensional model and ALS data. The revised study will include full assessment of the mainstream and overland flood behaviour for 2, 5, 10, 20, 100 and 200 year average recurrence interval and probable maximum flood in the Powells Creek and Saleyards Creek catchments. In addition Council intends to implement the same criteria for tagging of the flood affected properties that was used in the Cooks River and Coxs Creek Flood Study completed in 2010. As a result Council will obtain comprehensive information on overland and mainstream flooding for its northern catchments (Powells Creek and Saleyards Creek) identical to information acquired for Council&rlsquo;s southern catchments (Cooks River and Coxs Creek).

The Council of the City of Botany Bay

Mascot, Rosebery and Eastlakes Floodplain Risk Management Study and Plan

This project will involve assessing the risk to life and proposing suitable flood response modification options, including an assessment of the impact of the structural integrity of dwellings, duration of inundation, potential evacuation routes and evacuation capability for both mainstream and overland flow flooding. The study will also identify any flood modification management options and assess their feasibility, effectiveness and impacts.

The Council of the Municipality of Kiama

Surf Beach Catchment - Floodplain Risk Management Study and Plan

This floodplain risk management study and plan will provide detailed technical information on the extent of flood damages to properties identified in the previous flood study as being flood affected and will analyse and recommend a management plan in consultation with stakeholders to minimise these risks.

Wagga Wagga City Council

Wagga Wagga City Council - revised Floodplain Risk Management Study and Plan

In 2009, Wagga Wagga City Council adopted the Wagga Wagga Floodplain Risk Management Plan. The majority of the recommendations within the plan have now been completed or are in the process of being actioned.

Since 2009 Council has been active in progressing flood mitigation activities including two updates to the 2004 Flood Study, a major overland flow flood study and a whole of local government area flood study. The community and Council have also experienced two major flood events as well as numerous overland flood events.

The intention of this project is to revise the current flood risk management plan, including a vegetation management study and a cumulative developments impact strategy. The outcome will be a revised list of flood mitigation recommendations for Council to action in the future.

Walcha Council

Walcha flood warning system – investigation and design

This project is stage 2 of the Walcha Floodplain Risk Management Plan. Existing emergency management measures for flood warning rely on Bureau of Meteorology advice and other non-specific data. This project will provide a flash flood warning system which will use telemetry assisted rain and river gauges within the catchment to provide an earlier and more accurate flood warning. The project will also involve regular and ongoing community education and awareness programs.

Walgett Shire Council

Walgett levee upgrade: Stage 3

This is the third stage of an ongoing Walgett levee upgrade project. There is one more stage to be completed other than this one. Completion of this full levee upgrade is to provide one per cent protection to the Walgett community.

Warringah Shire Council

Narrabeen Lagoon flood mitigation (entrance clearance)

The Narrabeen Lagoon Flood Mitigation (Entrance Clearance) project aims to reduce the risk of flooding to low-lying areas surrounding Narrabeen Lagoon in the local government areas of Warringah and Pittwater.

Over time the entrance of Narrabeen Lagoon becomes in-filled with marine sand, which significantly increases the risk of flooding to public and private property in the lagoon floodplain. These works are expected to result in the removal of about 45,000 cubic metres of sand from the entrance of Narrabeen Lagoon.

This will significantly reduce the flood risk to approximately 1,500 dwellings as well as numerous state and regional roads. If the works are not undertaken there could be severe socio-economic and environmental impacts.

This project is of regional importance due to the reduction in the impacts of flooding to the Wakehurst Parkway which is a key transport route to the new Northern Beaches Hospital in Frenchs Forest.

Wingecarribee Shire Council

Gibbergunyah Creek Floodplain Risk Management Study and Plan: Stage 2

The Gibbergunyah Creek Floodplain Risk Management Study and Plan will suggest measures required to be undertaken to address the flooding problems identified in the Gibbergunyah Creek Flood Study: Stage 1.

Moss Vale Golf Course detention basin scoping study: Stage 3

The Whites Creek flows through the middle of Moss Vale township crossing the Illawarra Highway. A flood study and subsequent floodplain risk management study and plan were undertaken. In the risk management study, the construction a detention basin was found to be most appropriate measure to mitigate flooding. The basin would limit flooding of adjacent properties as well as reducing the frequency and duration of Illawarra Highway closure due to flooding.

Nattai Ponds Flood Study: Stage 1

The Nattai Ponds catchment is located partially in Mittagong and Braemar. The creek is unnamed and commonly called Nattai Ponds. There are two big residential subdivisions under development and it is expected that many will follow. It is Council's intention to undertake a flood study for the whole catchment to help plan for future strategic land use planning.

Nattai River Floodplain Risk Management Study and Plan: Stage 2

The Nattai River Floodplain Risk Management Study and Plan will prepare a risk management plan for the Nattai River catchment, Mittagong. The catchment is urban to semi urban in nature and rapid urban development is expected. The risk management plan will help Council in strategic planning to protect properties from flooding.

Robertson Village Overland Flow Study: Stage 1

The township of Robertson straddles the Illawarra Highway and has grown without a piped urban drainage system. As the town grows, Council receives flooding complaints relating to both private property and highway closure more frequently than before. As the town is situated in a very high rainfall area, a proper study will guide Council to take appropriate measures to save properties from flooding and limit the frequency and duration of Illawarra Highway closure by designing and constructing an efficient drainage system and implementing risk based controls for future development.

Paddington Flood Study

The suburb of Paddington drains into Rushcutters Bay. Woollahra Council acknowledge the need to map flood prone properties within the Paddington area where possible to introduce planning controls and construct flood mitigation works to protect people and property from future flood damage.

Wyong Shire Council

Ourimbah Creek Floodplain Risk Management Study and Plan review

The Ourimbah Creek catchment is located within both Wyong and Gosford Council local government areas and is surrounded by steep escarpments which drain onto floodplains before flowing into Tuggerah Lake. Significant areas of the floodplain have experienced flooding on a number of occasions and are subject to flash flooding, watercourses overtopping and elevated water levels within Tuggerah Lake.

Wyong and Gosford councils have adopted floodplain risk management studies and plans for various areas of the Ourimbah Creek catchment however these are up to 17 years old.

Following completion of the Ourimbah Creek Flood Study in 2013, the next stage of the process is to undertake a comprehensive floodplain risk management study and plan that includes both Wyong and Gosford local government areas. It is important that the study and plan be undertaken as one project as it recognises that any proposed works in one local government area may have an impact on the adjoining one.

Tuggerah Lakes Southern Catchments Overland Flood Study

An overland flood study of the Tumbi Umbi, Berkeley Vale and Glenning Valley catchments will be undertaken. This study will enable a hydraulic model to be developed for the catchments with associated flood extents, levels, depths, hazards and flood planning areas to be mapped.

Wyong River Flood Risk Management Study and Plan review

This project will review and update the existing Lower Wyong River Floodplain Risk Management Study and Plan using data from the recently completed Wyong River Catchment Flood Study (2013).
