Seaforth Park detention basin detailed design
This project involves a feasibility investigation and preparation of a detailed design that will result in construction ready drawings for the Seaforth Park detention basin in the Muddy Creek catchment, as recommended in the Bayside west floodplain risk management study and plan.
The proposed basin will be a tiered configuration, with a total capacity of 5,000 cubic metres. It will reduce flooding in a number of properties along its 500-metre flow path.

Lavenders Bridge replacement – investigation and design
This project will encompass investigation and design for a replacement of Lavenders Bridge in Bellingen. Lavenders Bridge crosses the Bellinger River and connects South Bellingen and North Bellingen. The existing Lavenders Bridge is a timber/concrete composite bridge that is regularly overtopped by flood water.
This project will involve assessing replacement options, a detailed survey, geotechnical investigation, preliminary design drawings, a construction bill of quantities and cost estimate of the preferred configuration.

Billinudgel rail bridge debris options study and implementation
This project will undertake an options study for debris control measures for the Billinudgel railway bridge. This action is a high priority within the North Byron floodplain risk management plan. The options study will include potential infrastructure improvements and recommended solutions.

Penstock valves – Grafton and South Grafton
Penstocks are one element of critical infrastructure that prevents flooding in Grafton and there are 24 penstock valves.
Council relies on staff that reside in Grafton to access this flood prevention infrastructure, to provide the required assistance during flood events. It currently takes 4 staff over an hour to shut one penstock, using a large heavy metal wheel.
This project aims to modernise, provide efficiencies and increase safety to the process of shutting penstocks, by installing motorised actuators on them. This will enable activation by pressing a button to close the penstocks.

Detailed feasibility study – Gloucester Road, Stoney Creek Road and Morgan Street
In 2023, Georges River Council completed an overland flow floodplain risk management study and plan, which covers Gloucester Road, Stoney Creek Road and Morgan Street at Beverly Hills. The community in these areas experienced significant flooding in 2021 and 2022.
This project involves a detailed feasibility study of the option to augment the drainage culverts under Stoney Creek Road and the railway corridor (adjacent to Morgan Street). If a feasible option is available, the consultant will then prepare concept design drawings and bill of quantities.

Narrabeen Lagoon entrance clearance project
North Narrabeen Lagoon is classified as an intermittently open and closed lagoon, where wave activity and ocean tides cause sand to infill and periodically close the narrow channel entrance. This natural build-up of sand significantly increases the risk of flooding in the floodplain surrounding the lagoon.
This project involves the extraction of up to 30,000 cubic metres of sand from the lagoon entrance and placing it on Collaroy-Narrabeen Beach. This action reduces flood risk by improving hydraulic efficiency, reducing the shallow water effect and friction caused by an infilled lagoon entrance.
The Narrabeen Lagoon entrance clearance project will reduce flood risk for approximately 2,066 properties, as well as public assets and essential infrastructure within the highly urbanised floodplain surrounding Narrabeen.

Bungendore overflow channel
This project involves the construction of an overflow channel that will pass under Tarargo Road on Turallo Creek in Bungendore; this is one of 3 physical flood mitigation measures proposed in the Bungendore floodplain risk management study and plan.
This channel will allow floodwaters to bypass the Tarago Road bridge crossing of the creek during flood events. The higher flows will be diverted across Tarago Road upstream of the bridge crossing, so that they will re-enter the creek downstream of the confluence of Turallo and Halfway creeks, directing flood waters away from properties in the Bungendore town centre.
The channel will also provide flood storage during major events, decreasing the flood impact on nearby properties.

Jock Brown detention basin – detailed design
The project involves design and environmental approvals for a detention basin in the northern part of the Elliot Lake-Little Lake catchment. The Elliot Lake-Little Lake floodplain risk management study and plan identifies 4 locations where a basin would be suitable, including Jock Brown Oval reserve, as a mitigation measure with a medium priority.

Murwillumbah central business district levee spillway upgrade – detailed design
In both 2017 and 2022 floods, the Murwillumbah central business district (CBD) levee suffered overtopping across the earthen section of the levee, which is prone to scour failure. A scour failure of the earthen levee has the potential to unleash a flood wave into the Murwillumbah CBD, which would have a significant impact on the town.
The Murwillumbah CBD levee and drainage study (2018) recommended the installation of a formalised spillway to achieve safe and controlled overtopping of the levee during events equal to or greater than the levee crest. Council has completed preliminary flood modelling, survey, and geotechnical investigation to facilitate a spillway upgrade of the earthen section of levee.
This project will complete a detailed design of a spillway and associated reconfiguration of the earthen section of the Murwillumbah CBD flood levee.

Aberdeen levee rehabilitation
This project will undertake a feasibility and option analysis to rehabilitate the Aberdeen levee, a crucial piece of infrastructure protecting the township from flood-related risks. It functions as a deflector levee and shields against smaller floods (up to the 50-year average recurrence interval) and redirects high-velocity flows during larger floods, safeguarding the township.
The project will assess the feasibility of various options to rehabilitate the levee; encompassing engineering assessments, environmental impact studies and stakeholder engagement.
