Launceston Flood Authority Annual Report - 2023

2. Introduction

The Launceston Flood Authority (LFA) was established by the Launceston City Council as a single Authority pursuant to the provisions of Section 30 of the Local Government Act 1993.

The LFA performs independent high level monitoring of the strategies employed to minimise flood impacts in Launceston's Flood Prone Area.

The LFA has achieved good progress in ensuring that the Launceston Flood Protection System continues to be maintained to a high standard and meets legislative compliance.

3. Launceston Flood Authority Board

4. kanamaluka / River Tamar Estuary Governance

Since the establishment of the Launceston City Deal in 2017, the governance for the kanamaluka / River Tamar Estuary was altered with the creation of the Tamar Estuary Management Taskforce (TEMT).

In 2020, the Launceston Flood Authority, along with the Launceston Chamber of Commerce, joined the Taskforce.

5. Chairman's Report

It is with pleasure that I present my annual Chairman’s Report for the Launceston Flood Authority (Authority).

Regular quarterly meetings have been held throughout the year to conduct the business of the Authority and, from these meetings a quarterly report on the activities of the Authority have been provided to Council.

At these meetings the City of Launceston (CoL) staff provide reports on the inspection and maintenance program of the flood protection infrastructure as well as the progress of the capital works program, to ensure works have been completed as programmed and on budget. Throughout the year the Authority has provided recommendations to the Council regarding several planning applications for developments in the flood inundation zone, and on occasions this activity has required out of session meetings and sharing of documents to meet the statutory timeframes for approval of applications by the Council

I have participated and attended all the Tamar Estuary Management Taskforce (TEMT) meetings to ensure the Authority was kept informed of their projects and activities.

The Authority has continued to work with TEMT on sedimentation management by continuing to undertake bathymetry surveys at six monthly periods.

Some of the key projects completed or commenced during the year were:

Continued development of the Launceston Flood Response Evacuation Plan, Completion of the Mowbray Levee penstock and pipeline repair, Commenced the Invermay Levee Reinstatement design and awarding of a construction tender for the work, Introduced a new Incident Management Policy and Framework, Implemented the learnings from the October 2022 flood.

I also participated in the Launceston Flood Recovery Exercise representing the Authority.

My term as a Director was recently renewed for a further four years and my role as the Chair for a further two years.

Finally, I would like to thank my fellow directors Robin, Ed and Michael for their commitment and support throughout the year and give a special thanks to our Council support team of Shane Eberhardt, Paul Gimpl, Erica Deegan, Maggie Gilligan, Nick Browne and Debbie Pickett for their assistance. A special thanks also to all Council staff both in the office and the field, for their efforts during the October 2022 flood event and for ensuring the City has an effective and operational levee system.

Greg Preece Chairman, Launceston Flood Authority

6. Compliance Matters

The Water Management Act 1999 requires dam owners to conduct mandatory comprehensive surveillance inspections every five years for 'significant and higher' consequence category dams, accompanied by a report submitted for review by the local dam regulating authority, Department of Natural Resources and Environment Tasmania (NRE Tas).

The Launceston Flood Protection System (the flood levees) requires mandatory surveillance and reporting due to its High A Consequence category dam category status. As a dam owner, we are also required to submit Work-As-Executed Reports for all completed dam works under our responsibility.

No compliance reports were submitted for the July 2022 - June 2023 reporting period.

7. Inspections, Monitoring and Minor Maintenance

Quarterly and annual visual inspections, as well as testing of existing backflow prevention structures i.e. floodgates, penstocks and tide flaps, were completed in a timely manner in accordance with our maintenance schedules. Following the inspections and testing, internal reporting and defect rectification were completed These rectifications included;

 Weed infestation management of East Launceston Levee within TasRail rail corridor

 Renewal of Levee Vegetation Management Contract

 Charles St Bridge floodgate closure exercise

 Repair of damaged pavers on levee walkways

8. Completed Projects

8.1. Penstock and Pipeline Renewal Mowbray Levee (MP1)

A damaged stormwater main was identified immediately upstream of MP1 during an inspection prior to a scheduled penstock renewal.

The penstock renewal has now been completed, including renewal of the stormwater main. Construction and installation required excavation of a section of Mowbray Levee. To improve the safety to Council staff while accessing this penstock, the penstock chamber was cut down to ground level during the penstock renewal.

8.2. Invermay Levee Bank Slip Remediation

A bank slip occurred next to the Invermay Levee (behind QVMAG, near Black Bridge) during Autumn 2023. It is suspected the scour of sediment due to the October 2022 floods caused the slip. This area has been prone to bank slips in the past and the footpath has previously been reinforced with sheet piling to prevent damage to the levee.

The slip was remediated with stabilising rocks and covered with soil and grass seed. Due to the unfavourable conditions the grass cover is still insufficient and will be continually topped up as needed.

9. Projects Underway

9.1. East Launceston Floodgates (EG2 & EG3)

Discussions are continuing with TasRail to replace the removable rail track sections between the floodgates on East Launceston Levee (EG2 & EG3) with concrete slabs TasRail are progressing the tender documentation for the construction contract, which will include the installation of Council slab tracks and flood gate amendment works. TasRail are targeting an early 2024 construction start date.

9.2. Invermay Levee Reinstatement

The Invermay Levee Reinstatement construction tender has been awarded to Gradco Pty Ltd after going to the Tender Review Committee in June 2023. Works are scheduled to begin in early 2023 with a programmed completion in March 2024

A geotechnical RFQ is underway to conduct cone penetrating tests and to install inclinometers and piezometers before the construction work begins.

9.3. Tamar Estuary River Health Action Plan (TERHAP) - TasWater New Sewer Pipeline Project

The CoL has been working closely with TasWater regarding works as part of the Tamar Estuary River Health Action Plan (TERHAP), combined system improvements projects. There are two main pipelines; the western rising main (Margaret St to TiTree Bend) and the eastern rising main (Racecourse Crescent to Ti-Tree Bend).

During the FY22/23 period, Council staff have been involved in multiple workshops around the design of the pipelines. Issued for Construction Drawings have been issued for the western rising main. TasWater have been continuously working with the Council and NRE to ensure any levee impacts are being appropriately considered and reinstated. There will be some impacts to the Paterson Levee near the Margaret Street pump station including a 2 m deep trench for electrical conduits in the levee crest. The main will be directionally drilled underneath Paterson Levee.

Figure 3 - Excerpt from concept design drawings for the Invermay Levee Reinstatement

Survey data will be taken both before and after the work to monitor for levee movement. The levee crest in this area is 7.2m AHD so a temporary trench has been deemed acceptable, provided that there is correct reinstatement.

TasWater have been reconsidering the scope for the eastern rising main project. At the moment, it is unlikely the eastern rising main will be delivered as part of the TERHAP project. A pipeline in this area may be constructed as part of the Launceston Sewerage Improvement Program (LSIP).

10. Emergency Preparedness

10.1. Incident Management Policy and Framework

In October 2022, the CoL's newly adopted Emergency Management Policy and Emergency Response Framework was tested under live conditions during a major flooding event across the north of Tasmania

The policy and framework was adopted by ELT in early 2022, with the aim to:

 Ensure that the organisation is best placed to effectively and efficiently manage and coordinate an incident response, either independently or as part of a broader multi-agency team.

 Make certain that the CoL is operating within a defined structure

Figure 4 - TERHAP Paterson Levee impacts

For the first time the CoL formally established an Incident Management Team (IMT) using the AIIMS framework to respond to the flooding event. This included:

 A number of strike teams (crews) who were pre-deployed around the municipality to respond at short notice to calls for assistance from the public.

 Formal levee patrols to ensure ongoing monitoring of the integrity of the levee network system while gates remained closed.

 Regular on ground Situation Reports from crews to provide intelligence on the occurrence and extent of flooding, particularly in the upper catchment.

At its very peak, the CoL had approximately 150 staff deployed to work purely on the incident, including a large portion of staff directly managing the flood levee network system. At the peak of flooding all gates and penstocks, with the exception of Taroona Street and the Charles Street Bridge were closed. A number of high volume pumps were also deployed to assist with dispersing water behind the levees.

The CoL has undertaken an internal de-brief and review of the flood incident including the effectiveness of the policy and framework. Overall the response efforts were deemed effective however there were with a number of key lessons learnt. These have subsequently been adopted to ensure continual improvement with processes and procedures. Further detail of the flood event is outlined in Section 11.

10.2. Flood Levee Patroller Training

Levee patrollers are utilised during flood events to help monitor the flood protection system. Training includes familiarisation with levee sections, awareness of current defects and areas of concern, what to look for in a flood (seepage, scour, slumping, observations of river levels) and how to appropriately communicate defects to the IMT.

Levee patroller training was completed throughout the year, with operational staff from City Services and Parks crews participating. Levee patrollers who assisted in the October 2022 floods have provided feedback for the role. They were found to be very helpful in capturing photos of the water levels, identifying defects and providing up-to-date information to the IMT.

10.3. Launceston Flood Response Evacuation Plan

In conjunction with the State Emergency Service and Tasmania Police, the CoL has reviewed and updated the Launceston Flood Response Evacuation Plan.

The Flood Response Plans objectives are:

 To ensure an appropriate level of preparedness of functional response structures to protect life and property

 To identify capabilities and support resources to assist in the response to a flooding event

 To enable a collaborative approach to existing operational and emergency management arrangements to ensure a planned and structured approach to response activities

The plan includes the formal adoption of Critical Decision Points for evacuation. When predicted levels reach the Critical Decision Points all available information will be assessed to inform if a voluntary or mandatory evacuation is required. This includes a risk assessment to guide the initiation of evacuation of the levee protected areas as forecast information of m³/s flow rates is received.

The plan was formally endorsed by the CoL Municipal Emergency Management Committee in September 2023 and is now waiting for formal endorsement at a regional and state level.

Figure 5 - Levee Patrollers during October 2022 flood event

10.4. Launceston Recovery Exercise

The Launceston Recovery Exercise was held in Launceston on 14 June 2023 with over 60 participants across different organisations attending. The event was held in collaboration with the National Emergency Management Agency (NEMA) and the Department of Premier and Cabinet (DPAC). The exercise scenario was a 1 in 500 year flood event, with participants exploring actions required from a recovery perspective three weeks after the event to 12 months and beyond.

The key themes from the exercise have been collated into a Considerations / Action Plan to inform future recovery planning. This work is being led by the CoL in collaboration with all recovery partners.

10.5. Disaster Ready FundFlood Intelligence & Early Warning Detection

The CoL has been successful in obtaining federal funding of $200k. This funding has been co-matched by the LFA, resulting in a $400k project. The project was discussed on local news platforms on 9 June following a media event.

Figure 6 - NEMA's Wendy Graham and Mark Drew with City of Launceston's Emergency Management Advisor Lynda Robins at the Launceston Recovery Exercise, 14th June 2023

The aim of the project is to develop an early warning detection system that will provide live data and visual intelligence. This will address gaps identified during recent floods and is expected to allow more time for critical operational decisions to be considered.

The project will also build on work currently being undertaken by the CoL's Engineering Cadet, Eliot Sotiriou, for his undergraduate honours program through Deakin University. Eliot's project is titled "Rainfall and streamflow of the North Esk catchment and the 2016/2022 Launceston Floods" and will be completed by November 2023.

10.6. Lift Local Grant - Supporting activities that strengthen planning for health and wellbeing

The CoL has been awarded a Lift Local Grant by the Tasmanian Government. The Lift Local Health grant will help the CoL to develop and deliver a communications and engagement strategy that will support higher participation in proactive measures to reduce individual and community impact at times of disaster and build longer term community connectedness.

Part of the grant will encompass those people who live within flood prone areas of the city, including those living in levee protected areas.

Figure 7 - City of Launceston Acting Mayor Matthew Garwood, Senator Helen Polley and City of Launceston Water Team Leader Erica Deegan at the Media Event, 9 June.

The grant funding with enable the CoL to:

Develop a set of key messages to distribute to the general population that will raise awareness of risk and support the community in preparing and recovering from disaster

Implement a sustainable and longer term approach to supporting community preparedness and resilience through community messaging

Update the CoL's digital assets to support consistent and timely messaging

Develop an interactive, easy to navigate website that raises awareness of risk and supports the community in preparing and recovering from disaster

11. Emergency Response - October 2022 Flood

The CoL staff members responded to a significant flood event during October 2022. A summary of the event and actions undertaken follows.

On 10October 2022, CoL officers observed the high potential of significant rain fall across the north of the state. Staff initiated monitoring of the situation and contacted key stakeholders advising of the observation. The Bureau made contact with the CoL on 11October, documenting the high chance of significant rainfall that would likely lead to moderate flooding within both the North and South Esk Rivers in the coming days. Based on the data provided the CoL enacted its Emergency Response Arrangements Framework and formally stood up an Incident Management Team (IMT) during the afternoon of 11October. Over the following 24 hours, predictions worsened with the Bureau forecasting 'major' flooding for the North Esk River.

By early morning of 13October, the CoL had its response plans in place including closing multiple flood levee gates and penstocks along the North Esk River. Crews were pre-deployed around various areas of the city to manage any flash flooding scenarios. A slow-moving rain band crossed Tasmania on 12 and 13October, before moving into the Tasman Sea on 14 October. The system brought heavy rain across northern Tasmania, with daily totals of 50 to 150 mm in the 24 hours to 9am on the 13th, followed by 50 to 200 mm to 9am on the 14th. Highest daily rainfall records were observed within the North Esk catchment at Nunamara, Mount Barrow and Musselboro rainfall stations. Tasmania as a whole had its wettest October day on record in the 24 hours to 9am on 14th

This exceptionally heavy rainfall impacted communities across North-West and Northern Tasmania, causing severe flooding in some locations For the CoL, significant flooding was seen in the North Esk Catchment, including the St Patricks River. Based on the intelligence coming from the ground the IMT checked the flood scenario forecast and recognised that what was actually occurring was much higher than previously forecast.

The floodgates within the TasRail yards at the East Launceston levee were installed at last light on 13October in preparation for the flood peak.

As the floodwaters travelled downstream, flooding predictions for the North Esk at Corra Linn significantly exceeded the major flood level and at one point was for a flood significantly larger than the June 2016 flood event. As a result, the flood levee gate in the Newstead levee was put in place as a precaution and a high volume pump transported to Newstead to manage stormwater flows

Another 'Bureau Flood Scenario' dataset was requested and by midnight, an order for evacuation was issued for the residents in the lower lying areas of Newstead. An Emergency Warning and Emergency Alert were issued with 75 properties door knocked by the SES. A number of residents relocated to other locations with 21 people presenting to the Evacuation Centre at Mowbray during the early hours of Friday morning. Multiple road closures were necessary across the North Esk floodplain interrupting traffic movement around the City.

Figure 8 - East Launceston Floodgate EG2 being closed in preparation for the flood peak.

By mid-morning on 14October, the North Esk River had peaked and the immediate threat to the community had passed. The CoL commenced rapid impact assessments to assess the damage throughout the municipality. The IMT focused on planning for the South Esk peak, which was expected at a 'moderate' level on 16 October

Figure 9 - Intersection of Johnston Road and Station Road, 12:18 am, Friday 14th October.

Figure 10 - North Esk Floodplain from Invermay Levee, Friday 14 October.

During 15October, crews worked to provide access to properties and started to repair infrastructure impacted by flood waters. Ongoing monitoring occurred around the South Esk River peak and as a precaution all levee gates and penstocks, with the exception of the Taroona Street and Charles Street Bridge, were closed. By 16October, all levee gates were closed (with the exception of Taroona Street and Charles Street Bridge) and the South Esk River peaked at approximately 0700 hours at Trevallyn Dam which resulted in a combined high tide and flood peak.

From 17October, ongoing monitoring of conditions continued with localised tidal flooding affecting roads, however formal response efforts ceased. The focus shifted to recovery, with the prioritisation to provide access to local residents returning home. Damage Impact Assessments were being documented and repair work prioritised based on community need. Approximately 35 community, sports clubs and businesses located within the flood impact zone were also contacted to understand damage and need for support. Outreach work indicated that six houses were directly impacted with approximately 16 people displaced. These properties were located in Nunamara and St Leonards.

The weeks following focused on clean up and repair to damaged infrastructure. Impact Assessments on infrastructure detailed approximately 86 major assets were damaged throughout the municipality which were having direct effect on the community.

Figure 11 - South Esk Floodwaters, Sunday 16 October

The CoL also completed a formal debrief of the event and documented lessons learned and areas for improvement (Flood Event October 2022 Operational Debrief, Feb 2023). The CoL staff also participated in multi-agency debriefs where invited.

12. Sediment Management

The Authority continued to work with the Tamar Estuary Management Taskforce (TEMT) to consider long term planning for the estuary and realise the vision for the estuary that was finalised in December 2021. The TEMT have now published the implementation plan 2023-2027 to deliver the vision.

The LFA continues to undertake regular bathymetry surveys of the upper estuary at six monthly intervals (autumn and spring) to monitor sediment volume and distribution. Significant scour was observed in the estuary as a result of the October 2022 flood event.

13. Independent Auditor's Report and Financial Statements as at 30 June 2023

Independent Auditor’s Report

To the Directors of the Launceston Flood Authority

Report on the Audit of the Special Purpose Financial Report

Opinion

I have audited the financial report, being a special purpose financial report of Launceston Flood Authority (the Authority), which comprises a statement of revenues and expenses (the Statement) for the year ended 30 June 2023, notes to the financial statements including a summary of significant accounting policies and the statement of certification signed by the Chairman.

In my opinion, the accompanying financial report presents fairly, in all material respects, the revenues and expenses for the year ended 30 June 2023 in accordance with the financial reporting requirements of Section 36A of the Local Government Act 1993 and the Authority’s Rules.

Basis for Opinion

I conducted the audit in accordance with Australian Auditing Standards. My responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial Report section of my report. I am independent of the Authority in accordance with the ethical requirements of the Accounting Professional and Ethical Standards Board’s APES 110 Code of Ethics for Professional Accountants (including Independence Standards) (the Code) that are relevant to my audit of the financial report in Australia. I have also fulfilled my other ethical responsibilities in accordance with the Code.

The Audit Act 2008 further promotes the independence of the Auditor-General. The AuditorGeneral is the auditor of all Tasmanian public sector entities and can only be removed by Parliament. The Auditor-General may conduct an audit in any way considered appropriate and is not subject to direction by any person about the way in which audit powers are to be exercised. The Auditor-General has for the purposes of conducting an audit, access to all documents and property and can report to Parliament matters which in the AuditorGeneral’s opinion are significant.

I believe that the audit evidence I have obtained is sufficient and appropriate to provide a basis for my opinion.

Emphasis of Matter - Basis of Accounting

I draw attention to Note 1 to the financial report, which describes the basis of accounting. The financial report has been prepared to assist the Authority to meet the financial reporting requirements of Section 36A of the Local Government Act 1993 and the Authority’s Rules. As

a result, the financial report may not be suitable for another purpose. My opinion is not modified in respect of this matter.

Responsibilities of the Directors for the Financial Report

The directors are responsible for the preparation and fair presentation of the financial report in accordance with the financial reporting requirements of the Section 36A of the Local Government Act 1993 and for such internal control as determined necessary to enable the preparation and fair presentation of a financial report that is free from material misstatement, whether due to fraud or error.

In preparing the financial report, the directors are responsible for assessing the Authority’s ability to continue as a going concern, disclosing, as applicable, matters relating to going concern and using the going concern basis of accounting unless they either intend to liquidate the Authority or to cease operations, or have no realistic alternative but to do so

Auditor’s Responsibilities for the Audit of the Financial Report

My objectives are to obtain reasonable assurance about whether the financial report as a whole is free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes my opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the Australian Auditing Standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of this financial report.

As part of an audit in accordance with the Australian Auditing Standards, I exercise professional judgement and maintain professional scepticism throughout the audit. I also:

• Identify and assess the risks of material misstatement of the financial report, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for my opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Authority’s internal control.

• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the directors.

• Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Authority’s ability to continue as a going concern. If I conclude that a material uncertainty exists, I am required to draw attention in my auditor’s report to the related disclosures in the financial report or, if such disclosures are inadequate, to modify my opinion. My conclusion is based on the audit evidence obtained up to the

date of my auditor’s report. However, future events or conditions may cause the Authority to cease to continue as a going concern.

• Evaluate the overall presentation, structure and content of the financial report, including the disclosures, and whether the financial report represent the underlying transactions and events in a manner that achieves fair presentation.

I communicate with directors regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that I identify during my audit.
