1.0 INTRODUCTION

This report is intended to assess and identify any light spill issues likely to impact neighbouring properties due to the construction of a new McDonald’s Restaurant in Eaton and provides artificial lighting design covering installation and control of various types of car park luminaires, externally mounted security lighting and general lighting to be installed at the proposed McDonald’s Eaton Restaurant. Any issues are to be assessed and qualified for action during the detailed design of the Restaurant. The proposal to operate 24 hours will be considered in the assessment. This report only covers the effects of carpark lighting installed at the restaurant. The report takes into account the location of topographical features, signage, roadway surfaces and reflectance from such surfaces, screen walls and the nearby residential properties located adjacent to the development.

3.0 BUILDING DESCRIPTION

The Eaton McDonald’s Restaurant is proposed to be located on Lots 2 and 3 Albatross Crescent. The development will comprise a typical single storey standalone McDonald’s restaurant and associated customer drive through and carpark. The restaurant is proposed to be located on the southern edge of the site adjacent to a two storey building located on the northern edge of the adjoining site.

The nearest residences are located to the west of the restaurant 70 metres away. Commercial and/or industrial properties are located to the east of the restaurant 50 metres away. Refer to Appendix A for property locations.

The specific exterior lighting to be installed at the proposed development site has been chosen for its durability and its control of the light spill from the horizontal plane. Consequently four different types of fittings have been specifically specified for use at this site.

1. Type X-3 - Car Park Pole Luminaires

Type of Fitting: LSI Hamilton XASU-3-LED-128-HO-CW-UE

Mounting Method: Affixed to the top of a 8m high pole

Quantity: Three (3)

2. Type X-F - Car Park Pole Luminaires

Type of Fitting: LSI Hamilton XASU-FT-LED-128-HO-CW-UE


Quantity: Four (4)

3. Type XS-3(W) - Car Park Pole Luminaires

Type of Fitting: LSI Hamilton XASU-3-LED-64-HO- CW-UE

Mounting Method: Affixed to the top of a 4m high pole or wall mounted at 3.5 or 4.5M as per

attacked drawings

Quantity: Three (3)

4. Type XS-F - Car Park Pole Luminaires

Type of Fitting: LSI Hamilton XASU-FT-LED-64-HO- CW-UE


Quantity: one (1)

The placement of the exterior artificial lighting is critical to meet the requirements of the Australian Standards and enhance the general safety and wellbeing of the public using this space. This has been considered in the section of the lighting locations as detailed in the Appendix B.

4.0 ASSESSMENT.

Light pole placement is generally selected to be around the premier of the boundary and positioned facing in to provide maximum illumination to the carpark with minimum light spill to adjacent properties.

The artificial lighting has been simulated across the site to determine the over spill of the various lighting sources employed at the site. The simulation has been conducted using manufacture provided photometric data and using specialised lighting design software AGI32. The following two scenarios are contained in the appendices:

1. The general spill of light spread over the entire public car park area on the horizontal plane, Appendix B;

2. The general spill of light spread of obtrusive light, Appendix C.

GCCM have under taken a further assessment of the potential light spill impacts associated with the proposed pylon sign. The assessment concluded that the proposed pylon sign is not designed to illuminate a particular area, it is designed to be visible from a distance. If we compare the light to other typical light sources in this environment we can get an understanding of the impact the light will have on the surrounding area -

• The sign is fitted with 1320 lm in total

• A typical 400W streetlight is 48000 lm

• A typical single 35 HID car head light is 2200 lm each (low beam)

• 10W domestic LED downlight 750 lm

The comparison light sources have clear diffusers and reflectors to maximise the light output, the sign has an opaque Perspex cover that is designed to illuminate, the effect of this Perspex cover will create a light loss factor and distortion. After the light loss factor and distortion of the fitting is considered, the sign is similar to a couple small domestic LEDs in terms of its lumen output and will not create a measurable lux level on any property boundary in the vertical or horizontal plan, added to this fact that the sign orientation is set so that it’s not directly facing adjacent residential properties, it’s impact on adjacent residential properties is considered negligible.

This is demonstrated in the attached light spill site plans which demonstrates the lux levels from other lighting within the site, including head lights exceeds the lux levels of the pylon sign which pass the maximum allowable illuminance. Therefore, the pylon sign illuminance level is considered to have minimal impact on the surrounding residential areas particularly in the context of other lighting in the District Centre including street lighting and intersection lights.

5.0 CONCLUSION

Following an assessment of the lighting design and their proximity to neighbouring properties the lighting is within Australian Standard levels as evidenced by the Obtrusive Light Compliance Report found within Appendix C.
