Flood reserve projects 2017-18

Nine projects valued at $979,000 have been activated from the reserve list for the 2017–18 Floodplain Management Program.

Project summaries

Blue Mountains City Council

Overland flow path improvements Luchetti 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 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.

Federation Council

Urana, Boree Creek, Morundah and Rand floodplain risk management plans

Urana, Boree Creek, Morundah and Rand were all impacted by floods in 2010 and 2012. This project will prepare risk management studies and plans for each community and identify possible flood management options within each town.

Narrabri Shire Council

Narrabri risk management plan and study

Narrabri Shire Council will prepare a floodplain risk management plan to get a better understanding of the flood behaviour and to identify potential flood mitigation works to reduce the damage from storms. This project will also investigate the feasibility of a flood by-pass and identification of properties appropriate for voluntary purchase.

Northern Beaches Council

Avalon detention basins feasibility study

The most beneficial flood modification option identified in the Avalon to Palm Beach floodplain risk management plan was the construction of detention basins in Catalpa Reserve and Toongarri Reserve in Avalon. The preliminary investigations into these two detention basins demonstrated a significant level of flood benefit and economic merit through the reduction of flood damages. This project will undertake further investigations on the environmental impacts and the community acceptance of these detention basins through a feasibility study.

Manly to Seaforth floodplain risk management study and plan

This project will develop a Manly to Seaforth floodplain risk management study and plan that will provide strategic direction for managing flooding in the suburbs of Balgowlah Heights, Clontarf and parts of the suburbs of Balgowlah, Manly, Fairlight and Seaforth.

The project will involve assessing the risk to life and will propose suitable flood response modification management options, including an assessment of the impact of structural integrity of dwellings, duration of inundation, potential evacuation routes and evacuation capability for both mainstream and overland flow flooding.

Shoalhaven City Council

Currarong Creek flood study

Currarong Creek originates from the highlands of Beecroft Peninsula and discharges to the South Pacific Ocean. This project will deliver a flood study that focuses on catchment, ocean and overland flooding within the Currarong area, including flooding from the various unnamed tributaries within the area.

Millards Creek flood study

Millards Creek is situated within the Shoalhaven local government area approximately 50 kilometres south of Nowra and centrally located in Ulladulla. This flood study will focus on flooding within the Ulladulla/Milton area as well as flooding from a number of unnamed tributaries within the area.

Wollongong City Council

Detailed design of debris control structures – Allans and Collins

This project will undertake detailed designs of debris control structures on Allans Creek and Collins Creek. The investigation and concept design phase found that the debris control structures will reduce the flood impacts by allowing the drainage network to drain effectively. The cost-benefit analysis results indicate that there are significant advantages to reducing economic damages to private property, as well as protecting key public assets including road and railway embankments from potential failure during storm events.
