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.

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

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.

Blue Mountains City Council

Overland flow path improvements Luchettie Avenue Hazelbrook

Overland flow from Luchetti Avenue presents a high hazard, with regard to depth and velocity of flood waters, for a number of properties. To protect these properties and ensure safe way out from Luchetti Avenue, Scullin Court and Lyons Place, this project will redirect the overland flow path to the natural creek line and the kerb height in front of flood-affected houses will be raised.

Camden City Council

Review of upper South Creek flood study in the context of ongoing development

The South Creek catchment is a high population growth area. This project will update the upper South Creek flood study with current aerial laser survey, ground surveys and drainage infrastructure for the catchment. This will provide an accurate regional flood model, flood mapping for a larger area of the catchment and flood data to assess development applications accurately.

Central Coast Council

Davistown and Empire Bay floodplain risk management study and plan

The foreshore areas of Davistown and Empire Bay have been subjected to flooding due to catchment rainfall and coastal stormwater inundation from Brisbane Water. This project will investigate various options to manage the risk of flooding and inundation on properties in the catchment of Davistown and Empire Bay. It will also recommend development controls and management measures to mitigate, or at least reduce the impact of future flood events.

Flood gauging network audit

This project will undertake a flood gauging network audit of the existing telemetry network of rainfall, water level and other environmental monitoring gauges, including The Entrance channel camera. The study will make recommendations about optimum gauge locations; maintenance and operations procedures and responsibilities; and potential for automated links to early warning network alerts and flood forecasting system.

Lake Macquarie catchments overland flood study

This project will carry out a flood study of the Lake Macquarie catchments. This study will enable a fully two-dimensional hydraulic model to be developed for the catchments, with associated flood extents, levels, depths, velocities, hazards, hydraulic categories and flood planning areas.

Wallarah Creek floodplain risk management study and plan

During periods of heavy rainfall in the Wallarah Creek catchment, there is potential for water to overtop the banks of the various creeks and waterways and inundate adjoining properties. There is also potential for the capacity of the stormwater system to be exceeded leading to overland flooding. This project will provide an understanding of the flood impacts and recommend and prioritise management options such as development controls, mitigation works, and evacuation routes to minimise potential risk to life and damage to property in any future flood event.

Woy Woy Peninsula floodplain risk management study and plan

The Woy Woy Peninsula is prone to flooding, in both short and long-duration rainfall events. Flooding occurs both in road reserves and on numerous residential properties throughout the peninsula. Large proportions of the foreshore areas are also subject to coastal storm inundation. This project will identify and investigate various options to manage flood risks in flood prone areas of the Woy Woy Peninsula to mitigate or reduce the impacts of future flood events.

Cessnock City Council

Black Creek (Cessnock) flood warning system concept design

This project will design a flood warning system that will provide early alerts to property owners and occupants, as well as local emergency services, of flood threats in Cessnock. The system is expected to lead to better flood preparedness and allow residents and emergency services to make more informed and timely decisions.

Swamp Creek flood warning system concept design

This project involves the design of a flood warning system to warn residents and local emergency services of flood threats to Abermain and Weston. The system is expected to lead to better flood preparedness and allow residents and emergency services to make more informed and time appropriate decisions.

The flood warning system will integrate factors such as rainfall, river flows and weather forecasts to predict the severity and timing of flooding then distribute warning messages.

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. This project will investigate the feasibility (taking into consideration the cost and intangible benefits) of a basin upgrade at this site and progress to detailed design if a feasible option is identified.

Hanwood stormwater pump and levee

This project will carry out investigation, detailed design, environmental and geotechnical investigations and preparation of specification for construction of stormwater pumps and associated drainage works at Mallee Street, Hanwood.

Following the investigation and design phase, a stormwater pump will be constructed. Once constructed, the project will provide much needed flood relief to the Hanwood community.

Reinstatement of decommissioned flood gates at East Mirrool Regulator

This project will reinstate flood gates at the East Mirrool Regulator, east of Yenda. Currently, Mirrool Creek's flow transfers under the main canal by means of a siphon structure. The siphon structure has a 5% annual exceedance probability capacity, in larger rain events Mirrool Creek overtops the embankments of the Northern Branch Canal and floods the townships of Yenda, North Yenda and Myall Park.

This project will integrate the existing siphon structure with reinstated flood gates, which will provide a 2% annual exceedance probability design flood capacity. This will increase the discharge capacity at the East Mirrool Regulator site to convey Mirrool Creek floodwaters and provide flood immunity to Yenda and surrounding areas.

Hilltops Council

Coogee Bay catchment – Rainbow Street trapped low point detailed investigation

Rainbow Street has a low point in the southern part of the Coogee Bay catchment, which is a deep depression with steep sides and no natural overland discharge point. During large flooding events, the capacity of the drainage pipe is exceeded and significant flooding occurs, up to depths of 1.7m for the 20% annual exceedance probability and up to 7m in the probable maximum flood event. This project will investigate the feasibility of drainage improvement to mitigate this issue.

Coogee Bay catchment – upper Dolphin Street drainage upgrade

This project will deliver ten additional inlet pits at 6 additional locations (2 locations have double pits and 1 location has 3 pits) in the Coogee Bay catchment. The additional inlet pits will be located at Clyde Street, along the upper Dolphin Street flow path, and Courland Street. This project will reduce frequency of flooding at locations which currently do not have an existing inlet pit to drain overland flow.

Feasibility study for lowering of Main Promenade – Maroubra

The area around Marine Parade and McKeon Street is lower than The Promenade behind Maroubra Beach. This causes flood water to pond until drained by the pipe network. In large events, floodwaters cannot flow overland out of the area until the ponding reaches the crest of The Promenade. This project will investigate the feasibility of lowering and widening the crest of The Promenade to prevent ponding in this area.

Rous City Council

Woollahra Municipal Council

Cecil Street floodway

The northern end of Cecil Street is a trapped low point where 2 major sub catchments meet. Currently, the only way for floodwaters to drain from this area is via the stormwater system. Consequently, above floor inundation is experienced in Cecil Street during relatively frequent rainfall events. This project involves the construction of a floodway/overland flow path between Cecil Street and Cecil Lane to reduce the potential for over floor flooding.

Yass Valley Council

Gundaroo basins scheme investigation and design

This project will develop concept designs for the David Street flow path basin, Morning Street flow path basin and upgrades to the culvert in Cork Street. The project will also identify any constraints associated with these works. These basins will capture flood waters and allow controlled release to reduce simultaneous flow path discharges and subsequent flooding within the township, while the culvert upgrade will allow enhanced conveyance of flood water.

Murrumbateman, Bowning, Bookham and Binalong flood study

The Yass valley is experiencing development pressure due to limited land availability in Canberra and Queanbeyan. Yass will exhaust its potential to accommodate future growth due to geographical and environmental restrictions, and future growth will shift to other village settlements including Murrumbateman, Bowning, Bookham and Binalong.

This project will undertake a flood study for Murrumbateman, Bowning, Bookham and Binalong to better understand the hydrology and flood behaviour in these areas. This flood study will inform local planning and infrastructure decision making, and will enable Council to appropriately manage the flood risks in these settlements.

Voluntary house raising scheme – Cessnock

This project aims to reduce flood damage to property in the area of South Cessnock where up to 20 properties suffer flooding in storm events from 5–20 year average recurrence index. Suitable properties will be able to apply for mitigation assistance through this scheme.

Coffs Harbour City Council

Boambee – Newports Creek Flood Mitigation Works Investigation and Design

There is extensive residential, commercial and industrial development on the floodplain, which includes the Coffs Harbour Health Campus which is the major-medical facility for the region, housing Coffs Harbour Base hospital and the local ambulance centre. North Boambee Road is cut off by flood waters by a 1 in 20-year event.

This project will implement works that are focused on lowering flood levels by improving the conveyance efficiency of the drainage system. They will lower one percent annual exceedance probability flood levels in the nearby industrial and commercial areas by up to 500 millimetres reducing the danger, inconvenience and commercial loss from flooding.

Boambee – Newports Creek Flood Mitigation Works: Investigation and Design Detention Basin

This project will develop a design for the North Boambee Valley detention basin, which is proposed to be constructed in the upper catchment adjacent to Englands Road. The basin will reduce one percent annual exceedance probability flood levels by up to 420 millimetres and adds to the effectiveness of the conveyance improvement also being carried out in this area.

Coffs Harbour Flood Mitigation Works – Upper Shephards Lane Detention Basin

Coffs Harbour was severely flooded in 1996 with one fatality and extensive property damage. Extensive property damage also occurred in the 2009 floods.

This project will construct the Upper Shephards Lane detention basin. The detention basin will halve the peak 100-year flood flow from 39 cubic metres per second to 20 cubic metres per second, resulting in the number of residential homes inundated by the 100-year flood dropping from 308 to 236 and will reduce flood levels by up to 0.42 metres at Grafton Street, Coffs Harbour once all the detention basins are complete.

Woolgoolga Flood Evacuation Investigation

The Sunset Caravan Park has about 170 dwellings that are flooded in a probable maximum flood. Virtually the entire site has a high flood hazard classification. Evacuation is required during major flood events, however the only evacuation route is cut by fast flowing deep floodwaters. This project is to investigate options for achieving improved flood evacuation access, as well as developing a detailed concept plan for the most feasible option.

Eurobodalla Shire Council

Batemans Bay Urban Creeks Flood Study

This project will prepare a flood study for urban creeks in Batemans Bay and will identify flood behaviour in the main urban areas. It is estimated that over 520 properties are potentially flood affected in the area including residential lots, caravan parks, a nursing home and two schools. The area will also be significantly impacted by sea level rise with the same flood affected properties being inundated by daily tides within a 50-year planning period.

This project will allow the different flood mechanisms on the coast to be identified and will inform a coordinated approach to identifying the different mechanisms associated with coastal flooding and inundation.

The scheme involves progressive acquisition of 175 properties within the floodway of the Georges River, in the vicinity of Rickard Road and Newbridge Road, Chipping Norton. To date Council has purchased 116 properties. The remaining 59 properties are required to be purchased to complete the scheme.

This project plans to purchase two properties at 36 and 38 Rickard Road, Chipping Norton. Following purchase, all structures from the property will be removed and the site will be converted into open spaces.

Lockhart Shire Council

Government dam upgrade/levee – Lockhart

This project involves the construction/upgrade of a levee and diversion channel in the vicinity of the government dams at the Lockhart North Common as well as land to the north east of the town. The levee will protect the adjoining south side residential areas from Brookong Creek flooding. The design is for an approximately 850 metre levee, with 30 metre spillway to discharge into Brookong Creek, as well as a 395 metre diversion channel to the north east. The number of residential and commercial properties flooded over floor is expected to be reduced by 22. In addition to this, many regions that are currently flood affected are expected to become flood free, thus reducing the number of flood affected lots by 75.

The Rock East – Streven Street Drain

In 2010 and 2012 The Rock township experienced the largest flood events in its history. This project will construct drainage channels and structures to the east of town to reduce flood risk. The drain upgrades will improve transfer of water from east of The Rock to Burkes Creek and will include upgrades of the railway line and Olympic Highway culverts as well as new drains. Fifteen fewer properties will be flooded over floor once this work is implemented and an average annual saving to the community of $71,400 per year is expected.

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.

Wagga Wagga City Council

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.

This project will take the information from the flood study and use it to formulate a management plan for flood risk and flooding in Deniliquin. This plan will then inform decisions such as future planning for Deniliquin and the setting of a flood planning level.

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

Fairfield Central Business District Floodplain Risk Management Study and Plan

The Fairfield Central Building District catchment is located in the western half of the Fairfield local government area (LGA) and covers 2.3 square kilometres. There are 7500 properties within the catchment, and about 2000 properties are included in the floodplain outline defined by the probable maximum flood event. This includes 57 parcels in the high (or partially high) flood risk precinct, 906 parcels in the medium (or partially medium) risk precinct and 1106 parcels in the low risk (or partially low) precinct. This flood risk management study and Plan will identify and prioritise various flood mitigation options to address existing, future and continuing flood risk issues in one of the Fairfield LGA most dense localities.

The project will assess the long-term cost and feasibility of maintaining key infrastructure and consider the practical options for modification, protection and retreat.

Scoping study Lake Macquarie foreshore voluntary house raising

This project is a scoping study for a voluntary house raising scheme for homes affected by flooding around the Lake Macquarie foreshore. This is an opportunity to use a financial incentive to help drive the pace of renovation and renewal of older homes, to lift them above the projected 2050 1 in 100 year flood level.

Survey to support local adaptation plans

This project will undertake a field survey of 1,600 properties to capture floor and property data which will be loaded into Council’s flooding database.

Upper Cockle Creek Flood Study and Flood Risk Management Flood Study and Plan review

Significant flooding of Upper Cockle Creek and its tributaries has been experienced on several occasions. The main issues this review project will address are: review and upgrade of flood study, hazards and hydraulic categories; assess the impact of climate change on flooding; and re-assess management options and strategies.

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.

Penrith City Council

College, Orth and Werrington Creeks Catchment Overland Flood Study

The College, Orth and Werrington Creeks Catchment is located about 49 kilometres west of Sydney between St Marys and Penrith. The study area lies in the Werrington Creek Catchment between the M4 and Dunheved Road and covers parts of Orchard Hills, Caddens, South Penrith, Kingswood, Cambridge Park, Werrington and Werrington County. The study catchment has an area of approximately 1200 hectares. The primary objective of the study is to define the flood behaviour under the existing floodplain conditions for a range of historical and design flood events. All potential flooding mechanisms will be included in the analysis including overland flow and creek flooding. The study will produce information on flood flows, velocities, levels, extents, and provisional hazard and hydraulic categories for a range of design flood events.

Little Creek Catchment Overland Flood Study

Little Creek Catchment is located about 45 kilometres west of Sydney, between Mount Druitt and St Marys. The study area lies between the M4 and Christie Street and covers parts of Oxley Park, Colyton and North St Marys. The study catchment has an area of about 480 hectares. The primary objective of the study is to define the flood behaviour under existing floodplain conditions for a range of design flood events in the study areas. All potential flooding mechanisms will be included in the analysis including overland flow and creek flooding. The study will produce information on flood flows, velocities, flood levels, extents, and provisional hazard and hydraulic categories for a range of design flood events.

South Creek Floodplain Risk Management Study and Plan

The project will undertake a floodplain risk management study and prepare a floodplain risk management plan for the South Creek catchment.

Richmond River County Council

Water Quality Monitoring – Richmond River Catchment

This project will undertake water quality monitoring. The water quality monitoring is linked to the flood mitigation systems as it triggers the opening and closure thresholds (water level and pH) of the floodgate.

Richmond Valley flood warning and evacuation planning system - rural home floor

This project will collect ground and floor level data that can be used in flood warning and evacuation systems and detail homes that are a priority for house raising or evacuation.

Lismore rural evacuation – house floor level plan

This project will survey the floor levels of houses in the most impacted areas. 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.

Shoalhaven City Council

Alexandra Street – Berry Town Creek vegetation and channel improvements

The Berry Town Creek vegetation and channel improvements project is the first stage of a program of works aimed to improve channel flow within the Town Creek system.

Strathfield Municipal Council

Powells Creek and Saleyards Creek Flood Study

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).

Sutherland Shire Council

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.

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).

Wallarah Creek Flood Study

This study will review the existing Wallarah Creek catchment flood study and enable a hydraulic model to be developed for the catchments, with associated flood extents, levels, depths, hazards and flood planning areas mapped.
