1       Introduction

1.1     Declaration of pecuniary interests, significant non-pecuniary interests and less than significant non-pecuniary interests

The provisions of Chapter 14 of the Local Government Act, 1993 (the Act) regulate the way in which Councillors and designated staff of Council conduct themselves to ensure that there is no conflict between their private interests and their public role.

The Act prescribes that where a member of Council (or a Committee of Council) has a direct or indirect financial (pecuniary) interest in a matter to be considered at a meeting of the Council (or Committee), that interest must be disclosed as soon as practicable after the start of the meeting and the reasons given for declaring such interest.

As members are aware, the provisions of the Local Government Act restrict any member who has declared a pecuniary interest in any matter from participating in the discussion or voting on that matter, and requires that member to vacate the Chamber.

Council’s Code of Conduct provides that if members have a non-pecuniary conflict of interest, the nature of the conflict must be disclosed. The Code of Conduct also provides for a number of ways in which a member may manage non pecuniary conflicts of interest.

Recommendation

It is recommended that Committee Members now disclose any conflicts of interest in matters under consideration by the Infrastructure Policy Committee at this meeting.

SUPPORTING INFORMATION

Road Maintenance

Crews have undertaken drainage improvements and road shoulder maintenance at:

·     Whiley Road

·     Ophir Road

Water Restrictions

The combined storage of Suma Park and Spring Creek Dams is 53.8%.  Residents are currently on Level 2 water restrictions.  Level 3 water restrictions will be implemented when the combined storage reaches 50%. 

Projecting forward, assuming no inflows (that is a worst case supply curve) and based on the current water demand we may enter Level 3 Restrictions as early as November 2018.  As such we will commence a Spring campaign on water savings in and around the home.  With good demand management and a return to Spring and Summer rains we may in fact improve our current storage and avoid Level 3 restrictions all together.

A Decision Support Tool Meeting was held on 6 August 2018 to forecast storage volumes for the current financial year and to determine the need to continue the transfer of supplementary raw water sources to Suma Park Dam during the July to September quarter. A bureau of Meteorology forecast for neutral conditions, trending to dry, generated the need for continued operation of all supplementary supplies.

Information on the Decision Support Tool, which is used to determine the need for the transfer of supplementary raw water sources, and a more detailed monthly summary of raw water transfers can be found on Council’s website at
https://www.orange.nsw.gov.au/water/oranges-water-supply/.

Drinking Water Quality

Water samples are collected as a component of Orange City Council’s Drinking Water Quality Monitoring Program which forms part of the NSW Health requirements. Samples are collected regularly and sent to a NSW Government National Association of Testing Authorities (NATA) accredited laboratory for analysis. Samples collected in July 2018 complied with the Australian Drinking Water Guidelines, 2011.

Water Consumption

Average daily water consumption during the week ending 16 August 2018 was 166 litres per person per day. 

The average daily city-wide water consumption for the period 21 July 2018 to 21 August 2018 was 12.02ML. 

Council is currently on Level 2 water restrictions with a total combined storage level of 54.01%.

Macquarie River Flows

The flows in the Macquarie River monitored downstream of Long Point (Station 421192) remained below the flow rate trigger to operate the Macquarie Pipeline (119 ML) for the period 25 July to 22 August 2018.

The chart below was sourced from the Water NSW website with flows presented in megalitres per day (ML/d).

CENTRAL TABLELANDS REGIONAL WATER SECURITY PROJECT – Orange To Carcoar Pipeline

The current date for practical completion of the Orange to Carcoar Pipeline by the contractor Leed Engineering is 30 November 2018.  In recent discussion with the contractor they expressed confidence in meeting this date.  

A small section of pipe between Lake Rowlands and the Carcoar filtration plant was removed from the contract when Central Tablelands Water (CTW) expressed an interest in installing it.  The pipe is onsite and CTW propose to commence work in February with completion expected in March. 

In discussion with Council’s insurers, Pure Technologies was engaged to utilise their “smart ball” technology to acoustically identify leaks along the vandalised effluent line between Orange and Spring Hill.  Based on preliminary pressure testing of the pipeline it appears that all holes have been identified and repaired.

Decommissioning of Hawke Dam

Within the next few weeks it is intended to invite tenders to decommission the large 130ML dam south of the Shiralee South Orange Development, formerly owned by Mr Ian Hawke.  Council purchased this dam because it posed a potential dam safety risk to the South Orange Development.

In decommissioning the dam, it is intended to convert it into a rural detention basin.  This will involve placing a low flow pipe in the base exiting into the development area where a future road and drainage will be constructed.  This will be complemented by a spillway to take flows of greater than 1 in 100 year flood events.  This dam will retard the peak flow of water from a 1 in 100 year storm to from approximately 6000 L/s to around 190 L/s.

As Council was informed that there were native fish in the dam, the contractor will be required to comply with an aquatic fauna relocation plan where native fish and trout are relocated to an appropriate alternate location.  A specialist consultant has been engaged to develop this plan.  Prior to the final design where a dry basin was adopted, the concept of maintaining a wet basin was explored, however this did not satisfy the dam safety requirements.

On emptying the dam it is not intended to remove the existing silt. While only minor planting around the inlet is intended, spray seeding of the larger exposed area with an appropriate seed and ameliorate mix will occur to provide quick stabilisation until natural vegetation establishes.

Old Hospital Site

Work has been completed on the removal of structures from the old hospital site.  On leaving the site the contractor replaced fencing and hydro seeded the exposed surface.  Council is now waiting on final reports from the contractor to be reviewed by Council’s auditor before issuing a final clearance certificate for the site.

AIRPORT PASSENGER NUMBERS

Passenger numbers for July 2018 were 6,769 compared with 5,491 in the same month in 2017.

 

 

Airport Energy Usage

Energy used at the airport during July 2018 was 28,251.24 kWh at a cost to Council of $7,274.03.


 

ENERGY USE

3.2     Be Seen. Be Safe. Drive With Your Headlights On

RECORD NUMBER:       2018/1868

AUTHOR:                       Andrea Hamilton-Vaughan, Road Safety Officer     

 

 

EXECUTIVE Summary

The Road Safety Officer is a shared resource with Orange City Council and Cabonne Council and funded by the Roads & Maritime Services through the Local Government Road Safety Program.

The Road Safety Officer develops and implements programs to address local crash characteristics from crash data collated by the Roads and Maritime Services. Crash data is reviewed in a five year period to detect trends for investigation and behavioural change campaigns. The goal is to reduce fatal and injury crashes in the Local Government Area based on statistical analysis.

The ‘Be seen. Be safe’ road safety campaign promotes behavioural change in local drivers in Cabonne and Orange to reduce fatal and injury crashes. The campaign is a call to action for local drivers to reduce their crash risk and drive 24/7 with their headlights on.

Link To Delivery/OPerational Plan

The recommendation in this report relates to the Delivery/Operational Plan strategy “3.2 Live - Partner with key stakeholders to deliver infrastructure and activities that improve the safety and security of the community”.

Financial Implications

There are no costs to Council associated with this campaign.

Policy and Governance Implications

A new policy would have to be developed if this recommendation is adopted by Council.

 

Recommendation

1        That Council supports the ‘Be Seen. Be Safe’ road safety campaign.

2        That Council considers the development of a policy recommending all fleet and plant vehicles to be driven 24/7 with their headlights on.

 

further considerations

Consideration has been given to the recommendation’s impact on Council’s service delivery; image and reputation; political; environmental; health and safety; employees; stakeholders and project management; and no further implications or risks have been identified.


 

SUPPORTING INFORMATION

Driving with your headlights on 24/7 has proven crash risk reduction benefits. To submit an application for funding from the Roads and Maritime Services, a project application was developed from national and international research studies including:

·   Literature review

·   Reviewed European and Australian research

·   Reviewed the benefits of lights use in daytime running lights

·   Consult the Australia Design Rule for daytime running lights ADR76/00 ECE Regulation 87

Identification of potential benefits in Cabonne and Orange Local Government Areas from Paine’s “A review of daytime running lights, a report by Vehicle Design & Research Pty Ltd to NRMA & RACV” found that according to European studies the potential reductions in crashes from daytime running lights (DRLs) are:

·   25% of daytime multi-vehicle fatal crashes

·   28% of daytime fatal pedestrian crashes

·   20% of daytime multi-vehicle injury crashes

·   12% of daytime multi-vehicle property crashes.

The largest reduction in crashes from daytime running lights would be in high severity crashes, including head-on and intersection crashes.

The Road Safety Officer will implement the Be Seen. Be Safe. Drive with your headlights on 24/7 campaign July to November 2018 and funded by the RMS.

To support this behavioural change campaign in the community, the Road Safety Officer requests that Orange City Council shows leadership in the community and supports the campaign by creating a drive with your headlights on 24/7 policy for all fleet and plant vehicles where applicable.

SUPPORTING INFORMATION

At the Infrastructure Policy Meeting of 9 July 2018, Cr Duffy requested a report be provided on smooth hot mix asphalt creating an ice skating effect in adverse weather conditions and how this issue can be addressed – in particular on Racecourse Road.

Clarification was later sought with Canobolas Road not Racecourse Road being the road in question.

Frost and Ice

Frost is usually a subset of what is generally known as ice and can be thought of as an ice dew that forms on surfaces when temperature and humidity conditions are optimal. Frost on its own in this form is not known to be particularly slippery. Ice and particularly what is referred to as ‘black ice’ is often formed when frost is crushed (under tyres) and melts and then refreezes. 

Normally frost and ice formation is patchy and subject to microclimate effects such as shadowing, topography, pavement thickness and composition. Incidents involving black ice have a propensity to occur around dawn as this is generally the coldest time of day and a time in winter when traffic starts to get busier on the road network.

On occasion ice formation is also due to the presence of thin films of water introduced by poor drainage issues.

Road Surfacing

As Council is aware, predominant road seal types in Orange include sprayed chip seals or alternatively hot mix asphalt.

Former head of the UK Transport Research Laboratory’s Investigations and Risk Management Department, Adrian Runacres provided the following advice in response to enquiries by Council staff regarding frost and ice formation on differing surfacing of roads;

‘Firstly, and very importantly, good drainage is an important factor in preventing ice from forming. Secondly, good macrotextureⁱ helps provide grip. Thirdly, the density of the surfacing and underlying construction, and the overall depth of construction can all make a significant difference. Denser materials and more deep constructions tend to even out temperature variations, and these materials take longer to cool down, for example, overnight. However, they also take longer to warm up during the morning, so the effect can be complicated. Roadside shelter / shadow effects can also have a significant effect in this regard and, in fact, this can be more important than the precise type of surfacing material.’

Aggregate particle roughness

Treatments

In most cases reactive treatment to frost, ice and snow formation on roads in Australia and throughout the world is as follows:

Frost > Salt spreading, liquid chemical or brine application

Ice > Salt spreading, liquid chemical or brine application

Snow > Mechanical removal of bulk followed up by salt spreading, liquid chemical or brine application

Proactive treatments can include:

·    Warning signposting, fixed and mobile.

·    Drainage improvements.

·    Spreading of grit (small aggregates).

·    Hydronic under road heating.

It is noted that the spreading of grit then requires the timely removal of the grit to prevent drainage problems and the grit becoming a hazard in itself. This is not seen to be a viable option as it is resource intensive and is not favoured by road authorities.

Whilst the texture of hot mix asphalt is far smoother than a sprayed seal, there are no practical options for improving that texture that would not in turn impede efficient drainage and result in icing problems.

It is Council staff practice to spread rock salt on slippery roads and footpaths when the ice hazard is known. It is not possible to spread the salt prior to ice formation as the rock salt will either be washed or swept away and over application can also be an environmental concern.

The de-icing salt Council uses is:

·    washed coarse salt

·    99.4% seasalt (NaCl)

·    average size 2.7mm.

It is a cheap standard industrial salt.

This is the same salt that Snowy Monaro Council use. National Parks roads in the high country are owned by the Roads and Maritime Services (RMS) but maintained by the Snowy Monaro Council (SMC) under contract. Advice from staff at SMC is that the majority of their road surfacing is a sprayed bitumen seal with limited hot mix asphalt surfacing, usually in the main town centres.  Information provided is that there is no different approach to either surfacing.

The RMS specify two products (information from Adrian Walsh – Project Manager for RMS Southern Region and manager of the de-icing subcontractor):

1.    dry rock salt (same as OCC) – limit at -4°C

2.    welt salt - a brine solution (salty water) limit at -6/-8°C – Note: the RMS contractor now uses advanced computer and GPS controlled machines that only spray the brine after it detects ice on the road. All logged with GPS, areas, application rate etc.

The salt, once diluted down in the stormwater system, at the quantities applied, 5 – 40g / square metre, become negligible from an environmental aspect.

Canobolas Road

Canobolas Road near the bus depot has two causeways crossing either side of a 90 degree bend in the road.  Given the flat nature of the surrounding farmland, these causeways quite often hold small amounts of water for extended periods of time which is tracked onto the surrounding road pavements by passing vehicles. When this water refreezes on the road surface it forms black ice. There has been one minor injury crash recorded in this location in the last five years in June of 2014. There is no indication whether or not the incident was related to ice on the road although the vehicle did leave the carriageway which typically indicates a loss of control.

A solution to this issue would be provide traditional piped culverts at the causeways to separate traffic from the water. A recent causeway replacement on Canobolas Road was undertaken for $157,000. Should Council choose, staff could develop designs and cost estimates to upgrade these causeways for consideration in future budgets.

3.4     2019 Water Industry Operations Conference and Exhibition

RECORD NUMBER:       2018/1662

AUTHOR:                       Wayne Beatty, Water and Sewerage Strategic Manager    

 

 

EXECUTIVE Summary

The Water Industry Association of Australia (WIOA) is a not-for-profit national association with a primary role of facilitating the collection, development and exchange of quality information between people undertaking operational roles in the water industry to assist Councils to ensure that policies and practices are in place to protect the sustainability and security of water destined for potable supply from the water catchment area.

WIOA has submitted a proposal for Council to host the Water Operations Conference and Exhibition from Monday 1 April 2019 to Friday 5 April 2019. Council has successfully hosted this event at the Orange PCYC in 2014 and 2015. The hosting of the conference in Orange allows a wider range of water staff to participate in the conference from across the region supporting best practice in water management and improved outcomes for Orange and the region.  It is recommended that Council accept the proposal to host the event for 2019.

Link To Delivery/OPerational Plan

The recommendation in this report relates to the Delivery/Operational Plan strategy “7.3 Preserve - Ensure that policies and practices are in place to protect the sustainability and security of water destined for potable supply from the water catchment area.”.

Financial Implications

In order for Council to be recognised as a host for the 2019 Water Industry Operations Conference and Exhibition, the Water Industry Association of Australia (WIOA) has requested a financial contribution of $10,000. This contribution will reduce the predicted surplus for the Water Fund in 2018/19 by $10,000. However, as described later in the report, the economic benefits are substantial along with demonstrating to the Orange community that Council is a leader in the field of Water Management.

Policy and Governance Implications

Recommendation

That Council supports the hosting of the Water Industry Operators Association of Australia Water Operations Conference and Exhibition in Orange in April 2019 by contributing $10,000 to the event.

 

further considerations

Consideration has been given to the recommendation’s impact on Council’s service delivery; image and reputation; political; environmental; health and safety; employees; stakeholders and project management; and no further implications or risks have been identified.

SUPPORTING INFORMATION

The Water Industry Association of Australia (WIOA) is a not-for-profit national Association with a primary role of facilitating the collection, development and exchange of quality information between people undertaking operational roles in the water industry to assist Councils to ensure that policies and practices are in place to protect the sustainability and security of water destined for potable supply from the water catchment area.

WIOA has submitted a proposal for Council to host the Water Operations Conference and Exhibition from Monday 1 April 2019 to Friday 5 April 2019. Council has successfully hosted this event at the Orange PCYC in 2014 and 2015.

The Conference goals are to:

·     distribute the latest technical and research based information through platform and poster presentations

·     update knowledge and skills of operational staff through interaction with fellow Water Industry employees; and

·     provide the opportunity to view and discuss the latest advances in technical equipment and services offered with suppliers and trade consultants.

Further details on the Conference and Exhibition can be found in the WIOA proposal (attached).

WIOA Awards

Prestigious awards are presented on the conference dinner night. These include two awards that Orange City Council has won in the past:

·     NSW Operator of the year award; and

·     NSW/ACT best tasting tap water competition.

Benefits to Orange

The hosting of the conference in Orange allows a wider range of water staff to participate in the conference from across the region supporting best practice in water management and improved outcomes for Orange and the region.

Hosting the conference will also contribute to the City’s economy, as WIOA is committed to using local suppliers for as much of the event as possible. Accommodation, cafés and restaurants increase business during the conference.

Hosting the conference demonstrates Council’s commitment to the community, and the NSW Water Sector, along with showcasing the facilities and water infrastructure within the region.

Further Comment

The Council’s general fund to support conference to be undertaken in Orange has been committed and the Council has previously declined to support new conferences.  However, the primary purpose of this conference is to increase accessibility for water operations staff to a key conference to promote best practice in Orange and the region.  As such, it is proposed that this initiative be funded from the Water Fund.
