Nil.

 

 

06       New Code of Conduct

Tim Molloy presented the report and there was discussion on conflict and disclosure provisions. Stuart Todd to be requested to provide a briefing on the Code at the next Sub-Committee meeting.

CONSENSUS:

 

That the information in and the attachments to the New Code of Conduct report be noted.

 

 

07       Hastings River Floodplain Risk Management Plan

 

Chris Thomas presented the report and provided an overview of the floodplain risk management process.

 

John Hough questioned the Interim Port Macquarie-Hastings LGA Flood Policy (2007) that if dwellings were destroyed (eg. by fire) the dwelling could be rebuilt. Gordon Cameron confirmed this is currently included in the policy (refer to s. 14.2).

 

Tim Molloy explained splitting the new Policy/DCP from the Management Plan. The Policy DCP component will be the subject of a future workshop with the Sub-Committee.

 

David Felsch questioned if the NSW government was removing dwelling entitlements from flood prone land. Dan Croft explained the PMHC LEP would retain provision for dwelling entitlements on existing holdings.

 

Trevor Sargeant questioned the legal obligation to undertake Flood Studies and Management Plans. Chris Thomas explained that the NSW Flood Prone Lands Policy states that local government is responsible for the management of flood prone land. The NSW Floodplain Development Manual (2006) outlines the practices required to manage flood prone land and the development of Floodplain Risk Management Plans is the main requirement. In addition, section 733 of the Local Government (LG) Act provides liability protection to councils from prosecution provided they have acted in good faith and in accordance with NSW Flood Prone Land Development Manual.

 

Graeme Sayer questioned if flood gauges are adequate. Chris Tomas advised that additional gauges are recommended as part of the risk management plan recommendations.

 

Sharon Griffiths questioned if North Shore ‘back flooding’ was in the model. Chris Thomas explained North Shore was included and provided details on the flood characteristics of North Shore.

 

Tony Day supported the road raising actions and advised the SES are seeking more manual gauges in the catchment.

 

Tony Day advised the SES is seeking to employ a GIS operator through the MidGOC to provide operation support with WaterRide during floods. Chris Thomas provided information on WaterRide and its ‘flood forecasting’ capabilities. Trevor Sargeant encourages a submission from SES.

 

Trevor Sargeant encouraged all members of the Sub-Committee to make submissions on the draft management plan.

 

CONSENSUS:

 

That it be recommended to Council, that the draft Hastings River Floodplain Risk Management Plan (2013) be placed on public exhibition for six (6) weeks, subject to the following:

·    Review and correction (if necessary) of the level on page 96 of the report relating to PL7 from 2.3mAHD to 2.4mAHD.

·    Exhibition material to include a statement regarding the requirement for Council to undertake the Flood Plain Risk Management Process in accordance with the NSW State Government Guidelines.

 

 

08       Camden Haven River and Lake System Flood Study

 

Chris Thomas presented the report and provided an overview of the exhibition process and the submissions received.

 

Garry Fajks questioned anomalies with recorded levels and Probable Maximum Flood (PMF) levels at Logans Crossing. Chris Thomas advised that he believes these may be related to incorrect gauge location coordinates and will confirm. An email will be provided to the Committee.

 

Sharon Griffiths questioned the different ocean levels adopted for the Hastings and Camden Haven Flood Studies. Chris Thomas explained the modelling procedure used including the different timing from the commencement of the storm to the flooding impacts.

 

Sharon Griffiths questioned if the new Pacific Highway was included in the model. Chris Thomas explained it was included.

 

Sharon Griffiths questioned the flood level of protection for the new Kempsey Highway. Chris Thomas explained various levels of service for road designs and indicated the RMS are reviewing their standards.

 

CONSENSUS:

 

That it be recommended to Council, that the Camden Haven River and Lake System Flood Study (2013) be adopted, subject to clarification of the height data for the Logans Crossing gauge being provided to Sub-Committee members.

 

 

09       GENERAL BUSINESS

1.       Tony Day requested an electronic copy of the final Camden Haven Flood Study.

2.       Tony Day advised of a new format required for (SES) Flood Plans containing three (3) phases. The first phase is proposed to be presented to the Local Emergency Management Committee (LEMC) by the end of 2013.

3.       Tony Day confirmed the new SES committee members are Tony Day and Ray Richards. Tim Molloy confirmed that Garry Faljks is welcome to attend as an observer given his Camden Haven knowledge and other SES members may also attend as observers.

4.       David Felsch again raised concerns of the Oakes Crescent residents  regarding the Floodway classification. David also questioned if Oakes Crescent properties would be acquired. Chris Thomas explained that land acquisition is generally not perused unless included in Management Plan actions. The Hastings River Floodplain Risk Management Plan does not include an action for acquisition.

5.       David Felsch sought information on the 2013 floods. Tony Day offered to provide a presentation to the next meeting.

6.       David Felsch believes the Dennis Bridge gauge is not working correctly. Gordon Cameron advised this is managed by MHL and not PMHC, however MHL will be requested to check the gauge.

7.       John Hough questioned the level of the February 2013 flood. Gordon Cameron advised ‘preliminary’ calculations indicate it was a 1:15 to 1:20 year event. No detailed calculations of the size have been received.

8.       Sharon Griffiths questioned the PMHC contact details for flood events. Tony Day advised the Director of Infrastructure is investigating changes to emergency details as part of Council’s new web site.

9.       John Hough questioned how flood warnings and alerts are issued. Tony Day explained process. Typically, the BOM issue flood warnings (eg. levels and times) via the Flood Watch system. The SES then need to interpret the data and produce local SES Flood Bulletins. There were some issues with the automatic mobile phone alert system, however this is being improved.

10.     Sharon Griffiths asked if any agencies were capturing aerial flood photos. Tony Day advised SES will capture photos if capacity is available.

 

 

 

The meeting closed at 3.55pm.

Further Explanation

(Local Government Act and Code of Conduct)

 

A conflict of interest exists where a reasonable and informed person would perceive that a Council official could be influenced by a private interest when carrying out their public duty. Interests can be of two types: pecuniary or non-pecuniary.

 

All interests, whether pecuniary or non-pecuniary are required to be fully disclosed and in writing.

 

Pecuniary Interest

 

A pecuniary interest is an interest that a Council official has in a matter because of a reasonable likelihood or expectation of appreciable financial gain or loss to the Council official. (section 442)

 

A Council official will also be taken to have a pecuniary interest in a matter if that Council official’s spouse or de facto partner or a relative of the Council official or a partner or employer of the Council official, or a company or other body of which the Council official, or a nominee, partner or employer of the Council official is a member, has a pecuniary interest in the matter. (section 443)

 

The Council official must not take part in the consideration or voting on the matter and leave and be out of sight of the meeting. (section 451)

 

Non-Pecuniary

 

A non-pecuniary interest is an interest that is private or personal that the Council official has that does not amount to a pecuniary interest as defined in the Act.

 

Non-pecuniary interests commonly arise out of family, or personal relationships, or involvement in sporting, social or other cultural groups and associations and may include an interest of a financial nature.

 

The political views of a Councillor do not constitute a private interest.

 

The management of a non-pecuniary interest will depend on whether or not it is significant.

 

Non Pecuniary – Significant Interest

 

As a general rule, a non-pecuniary conflict of interest will be significant where a matter does not raise a pecuniary interest, but it involves:

(a)   A relationship between a Council official and another person that is particularly close, for example, parent, grandparent, brother, sister, uncle, aunt, nephew, niece, lineal descendant or adopted child of the Council official or of the Council official’s spouse, current or former spouse or partner, de facto or other person living in the same household.

(b)   Other relationships that are particularly close, such as friendships and business relationships. Closeness is defined by the nature of the friendship or business relationship, the frequency of contact and the duration of the friendship or relationship.

(c)   An affiliation between a Council official an organisation, sporting body, club, corporation or association that is particularly strong.

 

If a Council official declares a non-pecuniary significant interest it must be managed in one of two ways:

1.     Remove the source of the conflict, by relinquishing or divesting the interest that creates the conflict, or reallocating the conflicting duties to another Council official.

2.     Have no involvement in the matter, by taking no part in the consideration or voting on the matter and leave and be out of sight of the meeting, as if the provisions in section 451(2) apply.

 

Non Pecuniary – Less than Significant Interest

 

If a Council official has declared a non-pecuniary less than significant interest and it does not require further action, they must provide an explanation of why they consider that the conflict does not require further action in the circumstances.

Item:          06

 

Subject:     Hastings River Floodplain Risk Management Plan

Presented by:  Development & Environment, Matt Rogers

 

 

 

 

 

RECOMMENDATION

 

That it be recommended to Council, to adopt the Hastings River Floodplain Risk Management Plan.

 

 

Discussion

 

In September 2013, Council resolved to place the Draft Hastings River Floodplain Management Plan on public exhibition for six (6) weeks.

 

The Hastings River Floodplain Management Plan (HFRMP) was prepared in accordance with the NSW Government’s Flood Prone Land Policy and guidelines outlined in the NSW Government’s ‘Floodplain Development Manual’ (2005). The HFRMP outlines a range of flood management options which were developed in consultation with representatives from Council, the then Department of Environment, Climate Change and Water (now the NSW Office and Environment & Heritage) and Council’s Floodplain Sub-Committee. The options were devised with a view to reducing the existing flood damages that the community could be exposed to and with a view to providing a mechanism for ensuring that the risk faced by future development was minimised.

 

The potential floodplain management options assessed comprise a combination of ‘flood damage reduction measures’ (structural measures) and ‘planning measures’ (non-structural measures).

 

The following structural measures are recommended for implementation as part of the HFRMP.

 

Option S1 – North Shore Levee (Scenario A) – West of Ferry Terminal. This option is expected to reduce the Average Annual Damage of flooding by $336,400. The capital cost of the works is estimated to be $1.2M.

 

OR

 

Option S2 – North Shore Levee (Scenario B) – West of Donnellys Creek. This option is expected to reduce the Average Annual Damage of flooding by $360,000. It is estimated that this option would cost about $1.6M.

 

(Note: Due to the inconclusive response from residents, implementation of Options S1 or S2 depend on community acceptance or a future change in flood policy)

 

Option S3 – Construct Settlement Point Flood Protection Levee. This option is expected to reduce the Average Annual Damage of flooding by $294,300.

 

Refer to Figure 2.7 of the HFRMP for the locations of the above options.

 

While listed as planning measures, PL1 includes the upgrade (raising) of various roads to improve flood evacuation and increase evacuation times. These upgrades are to be prioritised based on opportunities that may arise as a function of Councils capital works program for road infrastructure.

 

The roads recommended for upgrade and the estimated cost are shown in Table 6 of the HRFMP and is reproduced below.

The Hastings River Floodplain Risk Management Plan includes an Implementation Schedule that outlines the proposed delivery of all the recommended management options and indicative cost.

 

Consultation/Submissions

Extensive consultation has occurred throughout the development of the Hastings River Floodplain Risk Management Plan. The consultation phases are outlined below.

 

A community information brochure was distributed to the public in May 2002 seeking flood information (e.g. flood marks photos etc). The Hastings Flood Study (2006) was publicly exhibited in May 2005. A public ‘Information Session’ was also held for the community to discuss aspects of the flood study prior to its adoption.

 

Public consultation was again undertaken in March 2009 as part of the development of the Hastings River Floodplain Risk Management Study (2012) to gauge the community’s views on the various flood management measures proposed. A total of 2,584 brochures were distributed to residents in the catchment. Details can be found in section 6.2 of the Hastings River Floodplain Risk Management Study. The Hastings River Floodplain Risk Management Study was also exhibited for six (6) weeks in December 2011. A public ‘Information Session’ was also held for the community to discuss aspects of the Study prior to its adoption.

 

The draft Hastings River Floodplain Risk Management Plan was placed on public exhibition from 23 September 2013 to 8 November 2013. Given the Plan is a simple and concise document containing an outline of work done to date an ‘Information Session’ was not undertaken. Details of the exhibition were advertised in local print media.

 

Following the exhibition of the draft Hastings River Floodplain Risk Management Plan, a total of 26 written submissions were received. The following is a breakdown of the submissions received:

 

The following Summary Table outlines the main issues raised in the written submissions.

 

Summary Table - main issues raised

 

Issue and Response

1

Objects to raising Shoreline Drive (North Shore) due to restricted property access (cars, boats, caravans etc), drainage, pedestrian and bike access.

The Flood Modification measures presented by the Hastings River Floodplain Risk Management Plan are conceptual at this stage. Following adoption by Council and funding becoming available the detailed design process will begin which will develop the particular requirements of the proposed measure. Pedestrian usage, drainage, and private driveway access, specific levee locations etc will all be taken into account during this stage.

3

Residents coped with the recent 2013 flood. Does not believe the problem is as bad as made out.

Flooding which occurred in the lower Hastings Valley of early 2013 was a minor to moderate event (in the order of a 5% AEP [20 year] event). For planning purposes Council utilises the 1% AEP (100 year) food event. Evacuation times are predicted to be shorter and inundation levels are predicted to be higher for a 1% AEP event.


 

Issue and Response

4

Insufficient consultation with residents.

Extensive consultation has occurred throughout the development of the Hastings River Floodplain Risk Management Plan.

Consultation phases included:

* A community information brochure  distributed to the public in May 2002 seeking flood information (e.g. flood marks photos etc).

* The Hastings Flood Study (2006) was publicly exhibited in May 2005. A public ‘Information Session’ was also held for the community to discuss aspects of the flood study prior to its adoption.

* Public consultation was again undertaken in March 2009 as part of the development of the Hastings River Floodplain Risk Management Study (2012) to gauge the community’s views on the various flood management measures proposed. A total of 2,584 brochures were distributed to residents in the catchment. Details can be found in section 6.2 of the Hastings River Floodplain Risk Management Study. The Hastings River Floodplain Risk Management Study was also exhibited for six (6) weeks in December 2011. A public ‘Information Session’ was also held for the community to discuss aspects of the Study prior to its adoption.

5

Some confusion with road raising options (PL1) and Settlement Point ring levee option (S3).

The Hasting River Floodplain Risk Management Plan contains two (2) separate management options for Settlement Point.

Option S3 considers a ring levee and is what is termed a ‘structural’ management option. This option has considered a 100 year flood level (ie. approximately 1.5m above natural surface including 500mm freeboard). This is the desirable level that would allow development controls to be adjusted. However, ultimately a lower level may be adopted in any future investigation and feasibility study.

Option PL1 considers a range of flood evacuation improvements (ie. road raising). The minimum level considered is the 5 year event and is predicted to improve the current evacuation situation. Road raising options generally are integrated into current or future plans to reconstruct roads. That is, if council was to reconstruct a road - higher levels should be considered as part of the works.

Does not support the flood classification for Oakes Crescent and Fernbank Creek.

Parts of the Oakes Crescent and Fernbank Creek locality have been identified within the Hastings River Flood Study (2006) as being impacted by a Floodway. This Floodway was subsequently refined and confirmed during the Hastings River Floodplain Risk Management Study process using industry accepted methodologies that were endorsed by the Floodplain Management Subcommittee and Council.

 

A summary of all submissions and responses is attached.

 

The final Hastings River Floodplain Management Plan is attached.
