Marlborough District Council Roading Assets - Activity Management Plan 2015 - 2018 SECTION 1 EXECUTIVE SUMMARY in adjacent lamps or where traffic safety is compromised. Where three adjoining lamps are out there is a requirement to repair within eight hours of notification. Council receive very few complaints about the standard of street lighting within the urban areas. Considerable upgrading has occurred in recent years and Council regards lighting to be at appropriate levels. However a new NZ/Australia standard has recently been released identifying lighting levels required on different road types. Marlborough’s more heavily trafficked roads will not meet this standard. Extra funding is likely to be required to achieve this, at an estimated of $20,000 per annum. 1.6.12.4 Demand / Growth The street light infrastructure addresses a number of related requirements within the road network and the community generally. Safety in respect of traffic movements on roads generates the prime requirement for lighting, followed by pedestrian travel safety, crime prevention and security camera scene lighting. Marlborough Lines has been conducting trials in the use of LED lighting in a couple of area’s in Marlborough and has been monitoring the development of the NZTA national standard for LED carriageway lighting. The NZTA specification has matured from a research testing phase to an operational phase, as such the Marlborough District Council has adopted the NZTA standard with all new lighting installations and sub division’s now having to be installed with LED Lighting. Currently the street lighting asset only has 225 LED lights, as new sub divisions are developed and older lights are renewed we will see a considerable growth in the number of LED light installations, which should give measurable savings in energy consumption. Also there is a trend to install subdued or decorative ground mounted lighting in new sub-divisions for aesthetics, so will see an increase in these types of decorative lights in the asset register. Based on the above we will see a steady growth of the asset following the sub division trend, with the types of lighting asset changing from the legacy type lights to LED Lights. 1.6.12.5 Life Cycle Management The inputs required by the Electrical Regulations and by the standards for illumination effectively govern and control the life cycle of the street lighting asset. Where ever possible the lanterns and supports should be standardised to ensure cost beneficial stock control. Standardisation of lanterns for street lighting is currently based around high pressure sodium 70, 100, 150 and 250 watt and 70 watt metal halide. Now with the LED lighting models beginning to come on stream there will be some standardisation of this asset type to continue with this asset management philosophy. Management of new additions to the asset list includes attempting, where possible, to limit the types of decorative pole to one or two. This simplifies stock holding and seeks to ensure a guarantee of future supply. Council have committed to a programme to convert all street lights to LED over the next 6 years. This is estimated at a cost of $3m to be funded at $500,00 per annum. 1.6.12.6 Cost / Financial / FWP Using the new retendered amounts from the new Street Lighting Contract, the cost of the current level of service averages at $321,000 per annum. The breakdown of cost indicates routine maintenance and structural checks at $240,000 and renewals at $100,000. Current funding has routine maintenance and structural checks fixed at $180.000 and renewals at $80,000. The funding request for 15/16 and beyond has been reset to match contract commitment requirements. A small increase has been allowed from the 2016/17 year in alignment with the retendering or renegotiation of the street lighting contract. The forward works programme (FWP) is achievable within the current level of funding provided that the management of the renewal programme is continued. The FWP acknowledges the community preference for having an uncluttered streetscape by scheduling the undergrounding of electric feeds to street lights whenever system upgrades permit. The financial FWP for power supply is in line with the Councils current power supply agreement with Meridian Energy. 30 September 2014 Page 116 of Section 1
