DS-8.7 Streetlighting

Drawing Ref: T801

Streetlighting is defined as a lighting installation constructed for the purpose of illuminating the Road Zone or public car parking.

DS-8.7.1   Road Classification

Lighting classifications shall be determined as follows:

1. Street Lighting requirements are largely determined by the road classification and sub-category of the road. The road classification and sub-category shall be agreed by Council prior to commencing the design process
2. To determine the appropriate lighting classification and sub-category, sections 1.1 and 3.1 of AS/NZS 1158 shall be used. 

DS-8.7.2   Public Pedestrian Accessways

The following shall apply:

1. Public pedestrian accessways shall be illuminated so visual surveillance of the accessway from the roadway at night is possible. They shall be designed to minimise light intruding into dwellings. 
2. Accessways shall be lit to the appropriate P category as set out in section 3.1 of AS/NZS 1158. Table 2.2 of AS/NZS 1158 defines the criteria for determining the lighting subcategory. 
3. Luminaires shall be pole top mounted and high enough to be out of reach of vandals but low enough to allow access from a ladder. Consider the use of 4m high lighting columns to limit spill light.
4. Where the primary area to be lit is accessed by a road or path that also must to be lit, the accessway shall be lit to the same standard with lighting systems of similar appearance as those in the primary area.

DS-8.7.3   Pedestrian Crossings

The following shall apply:

1. All Pedestrian Crossing types shall be lit in accordance with AS/NZS 1158.4. Luminaires shall have a photometric distribution specifically designed to suit pedestrian crossings. 
2. At an un-signalised pedestrian crossing, AS/NZS1158.4 allows the use of a Belisha disc or a flashing Belisha beacon. Please contact Council who will advise which type is appropriate for the specific crossing.

DS-8.7.4   Lighting Near or at Permanent Traffic Management Devices

At traffic management devices such as roundabouts, speed tables, speed humps, pedestrian refuges etc that intend to:

1. Slow traffic on category P roads:
   1. 3.5 lux horizontal point illuminance shall be used in accordance with AS/NZS1158.3.1. 
   2. This is not additional to road lighting.
2. Deter traffic on category P roads:
   1. Install reflective devices as per the Manual of Traffic Signs and Markings (MOTSAM).

Contact Council for advice whether the local area traffic management devices have been provided to slow or deter traffic prior to detailed design commencing.

Refer to AS/NZS 1158.1.1 for lighting of traffic management devices on V category roads.

DS-8.7.5   Private Roads, Private Ways, Private Areas

The following shall apply:

1. Streetlighting for private-ways (rights-of-way) and privately owned accessways is the responsibility of the private owner and no private lighting shall be supplied electricity from the public streetlighting system.
2. Private streetlighting shall be designed to minimise the effects of the intrusion of light into dwellings.

DS-8.7.6   Rural Roads

Streetlights are not required for rural roads except as flag-lighting at intersections where required by Council. Streetlighting for rural areas is addressed in AS/NZS 1158.1.1 clause 3.5.

Since the ambient light and sky glow in rural areas is significantly less than in built-up areas, special care shall be taken to limit spill light and glare. In addition to this:

1. Street lighting shall comply with the minimum applicable standard for intersections and road terminations.
2. Minimise lighting beyond these areas. Only provide sufficient lighting so that a pedestrian walking along the road always has a light in view.
3. Priority shall be given to roads that are designated for traffic detours from main highways.
4. For isolated intersections, refer to NZTA M30.

DS-8.7.7   Reserve and Walkway Lighting

Reserve and walkway lighting includes all lighting for use in public areas not including the Road Zone or car parking. These may include column/lantern lighting, "up-lights", floodlights and any other lighting not otherwise specified in the IDC but approved by Council. The following shall apply:

1. The design of reserve and walkway lighting shall follow the requirements of the IDC. Where not specified a recognised design standard and/or design method approved by Council shall be utilised.
2. The electrical power supply to the reserve and walkway lighting from the reticulation shall be owned by Council.
