Presentations

SFM21.1 Floodplain Risk Management Presentation

HPERM Ref: D21/118892

John Murtagh, Department of Planning, Industry and Environment (DPIE), gave a presentation on Floodplain Risk Management in the context of the Shoalhaven, and the role of the Committee. The presentation was based on that given at the previous meeting on 25 November 2020, with updates, and is attached to these minutes.

SFM21.2 Draft Millards Creek Flood Study Presentation

HPERM Ref: D21/118896

Julian Skipworth of Water Modelling Solutions gave a presentation on the Millards Creek Flood Study, a copy of which will be circulated to the Committee.

Key findings:

· Princes Highway at Millards Creek inundated in fairly frequent events but to shallow depths.

· Piped Sections of waterway between Warden St and Spencer St, overtopped in 20% AEP event and higher. In 1% AEP event becomes very significant and hazardous.

· Ulladulla High School overland flowpaths evident in larger events; hazard remains low.

· Several areas where roadways become significant flowpaths (Princes Highway, St Vincent St, (Burrill St South).

· Several areas where roadways become overtopped in 1% AEP event (Croft Ave, Village Drive)

· Deeper inundation is generally well confined to waterways

· Risk to property is generally quite low other than some small pockets

· Some roads are overtopped and access is cut; however there are a few residential areas which become isolated.

· Sea level rise has minimal impact on flood risk on this catchment; impacts don’t extend beyond the harbour and lower estuary.

Julian confirmed the magnitude of the most recent flood event (March 2021) has not yet been investigated. He advised the depth of rainfall was expected to be less than the 2013/14 events that this model was calibrated to.

Developments since 2013-14:

Mark Stone (Senior Floodplain Engineer) advised there has been some recent development in the upper part of the catchment, but onsite detention is required by Council policy.

The implementation of onsite detention in future developments will prevent the magnitude of flood events increasing beyond that estimated by this flood study.

Reports

SFM21.3 Draft Millards Creek Flood Study

HPERM Ref: D21/93006

Mark Stone, Senior Floodplain Engineer, presented the Draft Millards Creek Flood Study. The presentation was to be circulated to members.

The report has been completed and feedback has been provided by Council, DPIE and SES. The next step in the project programme is community consultation and public exhibition, planned from 12 April to 7 May 2021. The outcomes from the community consultation and public exhibition will be reported to another Floodplain Risk Management Committee meeting which will seek endorsement for Council to adopt the Millards Creek Flood Study.

Clr Gartner asked whether some of the mitigations under the changes to the DCP would assist with insurance costs. Mark Stone advised this information would not be readily available to be part of the consultation. John Murtagh (DPIE) noted it would be difficult for Council to determine what the insurance industry’s response would be; this would be a useful discussion to have with the Insurance Council of Australia.

Recommendation

The Committee receive the Draft Millards Creek Flood Study report for information and endorse the commencement of community engagement for the Draft Flood Study.

RESOLVED (Michael Brungs / David Laidlaw)

That the Committee receive the Draft Millards Creek Flood Study report for information and endorse the commencement of community engagement for the Draft Flood Study.

CARRIED

General Business

SFM21.4 Northern NSW Flood Event 2021

Clr White asked about the recent floods in the Nepean River area. John Murtagh explained the impacts varies according to location. At Penrith the floods seemed larger. At Hawkesbury and at Windsor the event was in the ballpark of 10% to 5% AEP. All the flood events appear comparable until they approach very large, 1% AEP and above events. The analysis John has seen to date indicates it had not been a significantly large event at Windsor, but there were significant impacts further up the catchment, e.g. Picton, Camden. He has not yet seen analysis of the North Coast events, but he understood them to be in the 2% and above range.

John agreed the Lower Shoalhaven River can be subject to very extensive flooding. He will bring any analysis to Mark Stone for a future meeting of the committee.

Additional information is attached to these minutes.

SFM21.5 Appreciation - Work During Rainfall Events

Bill McInnes (SES) expressed gratitude to Council staff and DPIE staff for their information and rapid responses to his questions.

RESOLVED (Michael Brungs / Clr White)

That the Committee thank the Council staff and DPIE for their work during the heavy rainfall events in March.

CARRIED

There being no further business, the meeting concluded, the time being 5.28pm.

NSW Government Floodplain Risk Management Program

DPIE administers the program supporting Councils with:

§ Policy advice, including a Manual and series of technical guides as well as access to grant funding (available via the DPIE website).

§ Technical support from Regional Representatives with:

o Grant Applications.

o Technical Briefs.

o Review of Progress, Draft and Final Reports.

o Works Investigation, Design, Construction.

o Floodplain Risk Management Committee Operation.

o Councillor briefings when requested.

The DPIE Floodplain Risk Management contact for the Shoalhaven LGA is therefore an incredibly valuable resource to assist Council to deliver its responsibilities under the Floodplain Risk Management Program.

Changes to DPIE Floodplain Risk Management Representative

John Murtagh from DPIE has been Council’s floodplain risk management representative for many years. John has extensive knowledge of flooding issues within the Shoalhaven Region and has provided expert technical support for the majority of previous flood investigations undertaken by Council. His efforts and commitment to the Shoalhaven Region has been invaluable for Council to understand, and where possible, manage the flood risk to the Shoalhaven community.

John Murtagh has recently taken extended leave from DPIE and is therefore unavailable to attend this FRMC meeting. John asked that the following message be conveyed to all Councillors and the members of the FRMC.

“I would appreciate it if my heartfelt thanks for all the great collaboration I have received from the SCC Councillors, staff & communities could be conveyed to the meeting on my behalf”.

It is noted that Nathan Promfret will be taking over as the primary DPIE Regional Floodplain Risk Management representative. Nathan has extensive technical knowledge in floodplain risk management, in addition to knowledge of the Shoalhaven Region and Council are looking forward to working with Nathan and other DPIE staff on current and future flood investigations.

SFM21.8 Update on Councils Flood Program

HPERM Ref: D21/276763

Department: Environmental Services

Approver: Phil Costello, Director - City Development

Reason for Report

To provide Council and the Southern Floodplain Risk Management Committee (FRMC) with an update on Council’s Flood Program.

Recommendation (Item to be determined under delegated authority)

The Committee receive the report for information.

Options

1. The Committee receive the report for information.

Implications: Nil.

2. The Committee could choose to provide an alternative recommendation for consideration by Council.

Implications: Unknown.

Background

Council has a forward Flood Program which identifies and prioritises new and updated flood investigations for the Shoalhaven LGA. These flood investigations cover all phases of the floodplain risk management process from Flood Studies, Floodplain Risk Management Studies (FRMS), Floodplain Risk Management Plans (FRMP) and implementation of mitigation measures identified from these investigations.

Council can request grant funding from the Department of Planning Industry and Environment (DPIE), which administer the NSW Government Floodplain Risk Management Program. Flood investigations that are successful in obtaining grant funding are 2/3 funded by DPIE and 1/3 funded by Council.

A resolution of the Central FRMC meeting on the 21 April 2021 was that Council would provide an update on Councils Flood Program and priorities at the next scheduled FRMC meeting. As such, this report summarises Council’s adopted flood investigations, investigations which are currently underway, outstanding investigations, investigations that require an update and preliminary priorities for the completion of these flood investigations.

It is noted that flood investigations are typically recommended to be updated every ten years or following a significant flood event and/or changes within the catchment.

The majority of Council’s flood investigations were developed prior to the update to the Australian Rainfall and Runoff guidelines (ARR2019), which provide Australian industry guidelines for flood estimation. The ongoing Millards Creek Flood Study, Currarong Creek Flood Study, Lower Shoalhaven River FRMS&P and St Georges Basin FRMS&P are being developed in accordance with the ARR2019 guidelines. Council’s existing flood investigations will need to be progressively updated in accordance with the ARR2019 guidelines.

Summary of Flood Program Priorities

A summary of Council’s Flood Program and preliminary priorities are provided below. Flood investigations have typically been identified as either a High, Medium or Low priority. It is noted that ranking of flood investigations within each of the priorities has not been identified at this stage and these can change with time as a result of factors such as changes within each catchment, flood events and community expectations.

Council would welcome any feedback from the FRMC on the proposed forward Flood Program and associated priorities.

High Priority

§ Update to Lower Shoalhaven Flood Study and FRMS&P – in progress.

§ Update to St Georges Basin Flood Study and FRMS&P – in progress.

§ Update to Broughton Creek Flood Study and FRMS&P – Council has applied for DPIE grant funding and included Councils 1/3 contribution in the Delivery Program Operational Program (DPOP).

Medium Priority

§ Millards Creek FRMS&P. Ideally including Racecourse Creek, Mollymook Creek and Narrawallee Creek – Council intends to apply for grant funding for this investigation in the next round of DPIE grant funding.

§ Willinga Lake Flood Study and FRMS&P. Ideally including all creeks south to Pretty Beach – Council intends to apply for grant funding for this investigation in the next round of DPIE grant funding.

§ Update to Nowra and Browns Creek FRMS&P. Ideally including the entire Nowra urban areas.

Low Priority

§ Callala Creek Flood Study, Swan Lake Flood Study and Clyde River Flood Study. Council currently has limited flood information in these catchments. Callala Creek could be included with an update to the Currambene and Moona Moona Creek FRMS&P.

§ Currarong Creek FRMS&P.

§ Update to the Currambene and Moona Moona Creek FRMS&P, Kangaroo Valley FRMS&P, Bomaderry Creek FRMS&P, Burrill Lake FRMS&P, Lake Tabourie FRMS&P and Lake Conjola FRMS&P.

Detailed Summary of Flood Program

The following table provides a summary of Council’s adopted flood investigations, investigations which are currently underway, outstanding investigations, investigations that require an update and preliminary priorities for the completion of these flood investigations. A number of these flood investigations are recommended to be undertaken following the completion of major transport projects that are either underway or in the planning stage.

SFM21.9 Final Millards Creek Flood Study

HPERM Ref: D21/276759

Department: Environmental Services

Approver: Phil Costello, Director - City Development

Reason for Report

To provide the Southern Floodplain Risk Management Committee (FRMC) with an update on the Millards Creek Flood Study and seek endorsement from the FRMC for the Final Millards Creek Flood Study report to be adopted by Council.

Recommendation (Item to be determined under delegated authority)

The Committee receive the Final Millards Creek Flood Study report for information and endorse the adoption of the Final Flood Study report by Council.

Options

1. The Committee receive the Final Millards Creek Flood Study report for information and endorse the adoption of the Final Flood Study report by Council.

Implications: Nil.

2. The Committee could choose to provide an alternative recommendation for consideration by Council.

Implications: This option could delay the adoption of the Final Flood Study report, result in additional project costs and/or prevent the completion of a Flood Study within the project timeframe.

Background

The Millards Creek catchment and associated tributaries are located in Ulladulla, and discharge to the Tasman Sea through the Ulladulla Harbour.

The objective of this study is to improve understanding of flood behaviour and impacts, and better inform management of flood risk in the study area in consideration of the available information. The study will also provide a sound technical basis for any further studies if this is found to be required. The scope of this flood study includes investigating both riverine and overland flooding within the Millards Creek catchment.

The need for an updated Flood Study for the Millards Creek catchment was identified as part of Council’s floodplain programme. The study outputs will inform decision making for investing in the floodplain, managing flood risk through prevention, preparedness, response and recovery activities, and informing and educating the community on flood risk and response to floods.

Current Status of the Project

The Draft Millards Creek Flood Study report was presented to the Southern FRMC on 31 March 2021. The FRMC endorsed the commencement of the public exhibition and community consultation of the Draft Millards Creek Flood Study report.

The public exhibition and community consultation was undertaken from 12 April to 7 May 2021.

The Millards Creek Flood Study report has been updated as required based on the outcomes of the public exhibition and community consultation phase.

The Final Millards Creek Flood Study report has been completed. Council is seeking endorsement from the FRMC for the Final Millards Creek Flood Study report to be adopted by Council. A link to the final report was provided with the agenda for this FRMC meeting.

The Final Millards Creek Flood Study report will be reported to Council for adoption following the upcoming Local Government elections.

At the previous FRMC meeting, Council advised that some amendments to Development Control Plan Chapter G9: Development of Flood Prone Land are proposed, along with the development of an overland flooding policy as required. These documents would also be reported to Council following the upcoming Local Government elections following their completion.

The outcomes of the public exhibition and community consultation phase identified the need to progress the Millards Creek Flood Study through to a Floodplain Risk Management Study and Plan (FRMS&P). Following the adoption of the Final Millards Creek Flood Study report, Council intends to apply for grant funding from the Department of Planning, Industry and Environment (DPIE) to complete a FRMS&P for the Millards Creek catchment. It would be beneficial for this study to include additional waterways in the Ulladulla urban area such as Racecourse Creek, Mollymook Creek and Narrawallee Creek, which are also expected to have flood emergency response considerations.

Community Engagement

The first round of community consultation was undertaken between December 2018 and January 2019. A project website was published on Council’s Get Involved Page to inform the community about the Flood Study. This page was designed to obtain feedback from the community about their flooding experience within the catchment.

The public exhibition and community consultation was undertaken from 12 April to 7 May 2021.

The following forms of community engagement were undertaken during the public exhibition and community consultation phase:

§ Media release to inform the community of the community engagement period.

§ Mail out to all property owners and residents within the study area of the Flood Study.

§ An online questionnaire available through the project’s Get Involved website page to seek feedback from the community.

§ Community drop in session attended by the consultant Water Modelling Solutions, Council’s Flood Engineers, Floodplain Risk Management representative from DPIE and members from the NSW State Emergency Services (SES). This drop in session was held at the Ulladulla Civic Centre on 22 April 2021.

During the public exhibition period, a survey was made available via the Millards Creek Flood Study Get Involved web page. In summary, there were 257 visits to the Get Involved web page during that period and five surveys completed. The interaction with the page also included 64 downloads of either the study report, fact sheet or mapping.

Key feedback from the survey included:

§ Requests for Council to maintain vegetation in the creek and remove fallen trees, weeds, debris and general rubbish.

§ Concerns regarding the historic design of urban stormwater network in urbanised parts of the catchment and some damaged sections of the urban stormwater network.

§ Concerns regarding erosion at stormwater outlets that enter the creek.

§ Criticism of Council’s adopted sea level rise policy, with a view that the adopted projections are too low.

§ Comments about debris blockage at the North Street Bridge commonly occurring.

§ Comment that erosion issues in the creek were noted but not examined in the document. Erosion at stormwater outlets and accumulated sediment captured upstream of the weir on Millards Creek was mentioned. It was requested that a study be undertaken to identify sediment sources in the catchment and a program developed to effectively manage these.

The above comments did not require any changes to the Flood Study report or technical analysis. Comments received will, however, be considered during the development of a Floodplain Risk Management Study and Plan in the future.

It is noted that Council provided an individual response to all members of the community that completed the survey.

In addition to the surveys completed on the Millards Creek Flood Study Get Involved page, feedback was also received from the Ulladulla Unit of the NSW SES. Further technical information about flood intelligence has been included in the Final Millards Creek Flood Study report based on the feedback from the NSW SES.

It is also noted that Council’s Flood Engineers received numerous enquiries from members of the community during the public exhibition and community consultation period. A lot of these enquiries were from members of the community that were unable to access the electronic community consultation material or attend the drop in session for personal reasons. Council’s Flood Engineers were able to assist all of these community members with their enquiries.

Financial Implications

The Millards Creek Flood Study is 2/3 funded by DPIE and 1/3 funded by Council. There have been no increases in project cost beyond the original approved funding.

Assuming the FRMC endorse the adoption of the Final Millards Creek Flood Study report by Council, the project will be completed within the DPIE grant funding term.

Any potential project delays could however prevent the project being adopted by Council prior to the end of the DPIE milestone funding term and this could result in increased project costs.

Policy Implications

Council does not currently have a policy with regard to flood specific development controls that apply to locations mapped with overland flooding.

The inclusion of overland flooding in the Millards Creek Flood Study provides an opportunity for Council to develop a policy on overland flooding and associated minor amendments to DCP Chapter G9: Development on Flood Prone Land, to provide appropriate flood specific development controls for new and redeveloped buildings located in areas that have been identified as comprising overland flooding.

These documents will be reported to Council following the upcoming Local Government elections following their completion.
