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 (FGS)

The existing North Deniliquin levee does not protect against a 1% annual exceedance probability flood, as it has a relatively small design freeboard of 0.1m 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 0.5m is proposed to address the vulnerability for North Deniliquin.

Fairfield City Council

King Park detention basin upgrade investigation and design (FMP)

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 (FGS)

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.

Griffith City Council

Hanwood stormwater pump and levee (FGS)

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 (FGS)

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

Murrumburah flood study, floodplain risk management study and plan (FMP)

Currawong Creek and Murrimboola Creek have significant catchments which during times of high intensity rainfall, overtop the banks and impact upon dwellings and businesses in the Murrumburrah township.

This project will provide up to date flood risk information for Moulamein, and explore options for managing risk, including potential upgrade of the levee system. Moulamein is at risk of flooding from the Edward River and Billabong Creek. The town has a flood levee system, but recent audits have shown that the condition of the levee is questionable.

Nambucca Shire Council

Installation of radio telemetry on 2 flood gauges in the Nambucca River (FMP)

This project will install a radio telemetry systems on 2 flood gauges in the Nambucca River gauge system. The information from these gauges will inform the State Emergency Service during a flood event in the Nambucca River. The absence of this telemetry technology on these gauges was identified as a deficiency in the flood warning system during the preparation of the flood risk management study and plan for this area.

North Sydney Council

North Sydney Council local government area wide floodplain risk management study and plan (FMP)

The North Sydney area is susceptible to flash flooding that can strike with very little warning. These flash floods can cause serious damage to properties and a risk to life, as the water is generally traveling at very high speeds due to the steep nature of the terrain. North Sydney Council recently completed a flood study for the local government area, that identified the areas of potential flooding. This project will compile a comprehensive prioritised list of mitigation works to alleviate flooding issues within the North Sydney Council local government area.

Northern Beaches Council

Randwick City Council

Coogee Bay catchment – Rainbow Street trapped low point detailed investigation (FMP)

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 (FMP)

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 (FMP)

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 County Council

Woollahra Municipal Council

Cecil Street floodway (FGS)

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 (FMP)

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 (FMP)

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.
