Agenda of Floodplain Management Advisory Committee Meeting

CONFLICT OF INTERESTS

What is a “Conflict of Interests” - A conflict of interests can be of two types:

Pecuniary - an interest that a person has in a matter because of a reasonable likelihood or expectation of appreciable financial gain or loss to the person or another person with whom the person is associated.

Non-pecuniary – a private or personal interest that a Council official has that does not amount to a pecuniary interest as defined in the Code of Conduct for Councillors (eg. A friendship, membership of an association, society or trade union or involvement or interest in an activity and may include an interest of a financial nature).

Remoteness – a person does not have a pecuniary interest in a matter if the interest is so remote or insignificant that it could not reasonably be regarded as likely to influence any decision the person might make in relation to a matter or if the interest is of a kind specified in the Code of Conduct for Councillors.

Who has a Pecuniary Interest? - a person has a pecuniary interest in a matter if the pecuniary interest is the interest of the person, or another person with whom the person is associated (see below).

Relatives, Partners - a person is taken to have a pecuniary interest in a matter if:

· The person’s spouse or de facto partner or a relative of the person has a pecuniary interest in the matter, or

· The person, or a nominee, partners or employer of the person, is a member of a company or other body that has a pecuniary interest in the matter.

N.B. “Relative”, in relation to a person means any of the following:

(a) the parent, grandparent, brother, sister, uncle, aunt, nephew, niece, lineal descends or adopted child of the person or of the person’s spouse;

(b) the spouse or de facto partners of the person or of a person referred to in paragraph (a)

No Interest in the Matter - however, a person is not taken to have a pecuniary interest in a matter:

· If the person is unaware of the relevant pecuniary interest of the spouse, de facto partner, relative or company or other body, or

· Just because the person is a member of, or is employed by, the Council.

· Just because the person is a member of, or a delegate of the Council to, a company or other body that has a pecuniary interest in the matter provided that the person has no beneficial interest in any shares of the company or body.

Disclosure and participation in meetings

· A Councillor or a member of a Council Committee who has a pecuniary interest in any matter with which the Council is concerned and who is present at a meeting of the Council or Committee at which the matter is being considered must disclose the nature of the interest to the meeting as soon as practicable.

· The Councillor or member must not be present at, or in sight of, the meeting of the Council or Committee:

(a) at any time during which the matter is being considered or discussed by the Council or Committee, or

(b) at any time during which the Council or Committee is voting on any question in relation to the matter.

No Knowledge - a person does not breach this Clause if the person did not know and could not reasonably be expected to have known that the matter under consideration at the meeting was a matter in which he or she had a pecuniary interest.

Non-pecuniary Interests - Must be disclosed in meetings.

There are a broad range of options available for managing conflicts & the option chosen will depend on an assessment of the circumstances of the matter, the nature of the interest and the significance of the issue being dealt with. Non-pecuniary conflicts of interests must be dealt with in at least one of the following ways:

· It may be appropriate that no action be taken where the potential for conflict is minimal. However, Councillors should consider providing an explanation of why they consider a conflict does not exist.

· Limit involvement if practical (eg. Participate in discussion but not in decision making or vice-versa). Care needs to be taken when exercising this option.

· Remove the source of the conflict (eg. Relinquishing or divesting the personal interest that creates the conflict)

· Have no involvement by absenting yourself from and not taking part in any debate or voting on the issue as of the provisions in the Code of Conduct (particularly if you have a significant non-pecuniary interest)

Committee members are reminded that they should declare and manage all conflicts of interest in respect of any matter on this Agenda, in accordance with the Code of Conduct.

RECORDING OF VOTING ON PLANNING MATTERS

Clause 375A of the Local Government Act 1993 – Recording of voting on planning matters

Report

Rear Drainage Easements Upgrade – South Golden Beach

This project focuses on enhancing rear easements through on-ground works from the planning process. With a budget of $300,000, the project's objective is to mobilise work crews to clear all drainage easements. Currently, the project scope includes conducting detailed site inspections, identifying issues on all easements, engaging a surveyor to survey all easements and mark the centre line, engaging an ecologist for the REF and Ecological Report, and gathering all information required for future funding applications.

The site survey, the review of environmental factors (REF) reporting, and the ecological assessment have been completed.

A survey of the drainage easements intended for works is supplied as Attachment 2.

The remaining budget will be allocated towards designing access to the easements to enable machinery deployment for clearing work, as the site is currently inaccessible in several areas, hampering maintenance efforts.

Details and ongoing updates are supplied on Council’s website at the following URL:

Staff Reports - Infrastructure Services 4.3

Report No. 4.3 Performance of Automatic Warning Signs for Water Over Main Arm Road, West of Sherrys Bridge

Directorate: Infrastructure Services

Report Author: Ryan Van Doorn, Flood & Drainage Engineer

File No: I2025/297

Summary:

Following the flash flood event on 1 December 2024, Byron Shire Council assessed the effectiveness of the automatic warning signs on Main Arm Road. Internal investigations identified that the warning signs were in operation when the incident occurred, however four vehicles continued to enter the waterway, were washed off the road and one occupant required rescuing from a tree.

The vehicles involved in the incident were likely returning from an event at Durrumbul Hall, with heavy rain falling and river levels peaking at 4 metres around 1 AM.

An occupant claimed the sign's height (3 metres) hindered visibility, causing confusion about the flashing lights.

The sign displaying “ROAD SUBJECT TO FLOODING DO NOT ENTER WHEN FLOODED” was set at 2.2 metres above the road, compliant with Australian Standard AS 1742, which recommends a minimum height of 1.5 metres. The nominal sign design is supplied in Attachment 1. A higher placement of the sign ensures better visibility and deters vandalism. Lowering the sign by 700mm would reduce flood immunity and early visibility, risking driver safety.

Although ‘Variable Message Signs’ were considered, their higher cost would limit sign installation across the shire. Ultimately, Council officers reviewed the performance of the Automatic Signs and confirmed that the status of the devices during the flash flood event was operational. Therefore, on review, advice was supplied by the assessing officers that the heights of the flood warning signs remain unchanged. The Committee recommended that this item, tabled on 20 February 2025, be deferred to a subsequent meeting. The recommendation from staff remains the same and seeks Committee’s acknowledgement of the recommendation.

RECOMMENDATION:

That the Committee notes the staff investigation and decision not to adjust the height of the Main Arm flood warning signs.

Report No. 4.4 Byron Shire Council Flood Risk Management Plans - Update on Actions and Accomplishments - Post 2022 Flood Priorities

Directorate: Infrastructure Services

Report Author: Ryan Van Doorn, Flood & Drainage Engineer

File No: I2025/574

Summary:

On 20th February 2025, Council staff provided the Flood Advisory Committee with a historical overview of the Byron Shire Council's three adopted Flood Risk Management Studies (FRMS) for its primary riverine catchments. Accompanying these studies are individualised and corresponding Flood Risk Management Plans (FRMP), which detail floodplain characteristics, known flood behaviours, and potential mitigation options.

These Flood Risk Management Studies are accordingly titled the North Byron (Brunswick) River Catchment (2020), the Tallow Creek Catchment (2009), and the Belongil Creek Catchment (2009). These flood studies were initiated to be upgraded following Council resolution 22-349. On October 11, 2022, the Flood Advisory Committee approved 64 prioritised actions based on the Flood Risk Management Plans. The details and current statuses of the 64 prioritised actions are supplied in Attachment 1.

To facilitate a visual progress of these items since 2022, a timeline of current, past and ongoing projects is supplied in Attachment 2. In summary, a large body of work has progressed since the priority project list’s inception and of core focus for Byron Shire Council are 18 remaining projects.

Similarly, to enhance public awareness of Council’s current Floodplain Risk Management activities and as per the Flood Risk Advisory Committee’s previous recommendations, a website has been created to display, describe and provide status updates on the 64 priority projects tabled at the previous committee meeting.

In addition to the progress updates, the flood advisory committee recommendations requested an update to be provided regarding the Post Event Flood Planning Level Review (item 23 – Attachment 1) and the Evacuation Assessment for Mullumbimby (item 12 – Attachment 1). Details on their progress are provided in the report below, however, can be summarised as awaiting grant funding to advance the Post-Event Flood Planning Level Review project and collaboration with NSW’s reconstruction authority department is ongoing.

Finally, Council’s Media and Communications Coordinator, is available to this Flood Risk Advisory Committee to support discussions regarding community engagement of the FRMS and FRMP programmes, as requested.

RECOMMENDATION:

That the Floodplain Risk Management Advisory Committee:

1 Recommends that Council notes and endorses the update on the 2022 Byron Shire Council Flood Mitigation Program, Attachment 1 (#E2025/48375)

2 Acknowledges that the 64 priority projects and their supporting information have been added by Council officers to the Byron Shire Council website for community awareness

3 Recommends that Council notes the progress of the Belongil and Tallow Creek Floodplain Management Study and its supporting Draft Calibration Report, Attachment 2 (E2025/48109).

4 Notes that the Grant application for the Brunswick River and Bangalow Flood Risk Management Plans have been submitted.

5 Notes that the Evacuation Assessment for Mullumbimby project is led by the NSW Reconstruction Authority and acknowledges its current status as in progress.

6 Acknowledges Council’s Media and Communications Coordinator attendance at the May 15th 2025, Floodplain Risk Advisory Committee Meeting.

7 Recommends Council consider the acquisition of software (TUFLOW) for ongoing FRMS hydraulic model development, maintenance, development assessment and optioneering purposes.

Report

As per the February 2025 Flood Advisory Committee meeting minutes, to enhance public awareness of Council’s current Floodplain Risk Management activities, Council officers have added webpage content to Byron Shire’s website to display, describe and provide status updates on the 64 priority projects tabled at the previous committee meeting. The website housing this additional information has been added to:

https://www.byron.nsw.gov.au/Council/Plans-Strategies/Planning-Development-Strategies/Flood-Planning-and-Management-Studies.

Similarly, the flood advisory committee recommendations requested an update regarding the Post-Event Flood Planning Level Review (item 23—Attachment 1) and the Evacuation Assessment for Mullumbimby (item 12—Attachment 1). A status update is provided below for these two items.

In addition to the requested items, it is important to note Byron Shire Council will be receiving flood studies from external consultants in a software format called TUFLOW. As Byron Shire Council does not have a TUFLOW licence or software installation, it is highly dependent on external consultants to perform hydraulic analyses or drainage improvement investigations when using this supplied model. As Council’s new Flood and Drainage Engineer has this expertise in operating TUFLOW and undertaking impact assessments, Byron Shire Council would benefit from acquiring a TUFLOW licence and building its in-house expertise to minimise cost to the community. The costing to acquire TUFLOW is supplied in Attachment 4, and support from the Flood Advisory Committee to acquire this software is sought to help build Byron Shire Council’s internal capabilities.

Post-Event Flood Planning Level Review

This project is ongoing and is envisaged to span until 2028. It is essentially dependent on the engagement and completion of the Brunswick River Flood Study. Council’s current website details the following regarding this project:

The NSW Department of Climate Change, Energy, the Environment, and Water has published all of its post-2022 Event Flood Behaviour Analysis Reports on the NSW SES Flood Data Portal.

· Post Event Flood Behaviour Analysis of the March 2022 Event - Brunswick River Report

· Post Event Flood Behaviour Analysis of the March 2022 Event - Belongil Creek Report

· Post Event Flood Behaviour Analysis of the March 2022 Event - Tallow Creek Report

The reports aim to understand the areas impacted by the recent 2022 flood event and determine the current approved flood model's ability to replicate the event.

While the reports' findings provide various recommendations that Byron Shire Council supports, we will not be making any changes to our planning instruments at this stage.

In order to do this, we would need our own updated floodplain management plan for each of the catchments in the Shire.

The tenders to review the Belongil and Tallow Creek Floodplain Management Plans are currently under review and successful consultant will be engaged soon. These have been funded by NSW Government's Floodplain Management Grant Program.

Council will seek a further grant to complete a review of the North Byron Floodplain Management Plan as part of the 2025 NSW Government's floodplain management grant program. At this stage Council does not have budget to make an application in this year's round that closed on 16 May 2024.

All reviews will involve working closely with our established Floodplain Advisory Committee and other stakeholders.

Since this publication, Water Modelling Solutions has been engaged to undertake the Belongil and Tallow Creek Floodplain Management Study, and the draft Calibration report is supplied as Attachment 2.

Similarly, Byron Shire has since allocated a co-contribution budget to undertake the North Byron Floodplain Management Study, and its accompanying grant application has been compiled and submitted to the NSW Government floodplain management grant program. Council staff have closely liaised with, consulted with, and had the application reviewed by the Department of Climate Change, Energy, Environment and Water (DCCEW) stakeholders.

Notification of the grant submission’s application outcome is anticipated by June 2025. Grant submission deadlines were extended to the 28^th of May 2025, due to the exceptional circumstances related to TC Alfred.

Evacuation Assessment for Mullumbimby

The Evacuation Assessment for Mullumbimby is a project led by NSW’s Reconstruction Authority in consultation with Byron Shire Council. The NSW Reconstruction Authority is in the process of developing a Multi-Criteria Analysis tool aimed at prioritising various low point options within Local Government Areas (LGAs) and the wider region. The finalisation of this tool is still underway, yet some key roads have been preliminarily identified and are supplied as Attachment 3. The roads considered for evacuation assessment and potential improvements are provided as attachment. Request for Quote (RFQ) documentation is also being prepared to undertake localised flood modelling around key options across the region. Staff are in consultation with the Reconstruction Authority.

A request by staff has been submitted for a presentation by NSW’s Reconstruction Authority to provide an update on this project’s status once options are identified and prior to analyses commencing.

Community Consultation

Finally, Council’s Media and Communications Coordinator, is available to this Flood Risk Advisory Committee to support discussions regarding community engagement of the FRMS and FRMP outcomes.

Next steps

Await the outcome of the Brunswick River FRMSP grant submission.

Await the Multi-Criteria Analysis from the NSW Reconstruction Authority for proposed flood evacuation route options.
