5 South Bristol Link road Obtrusive Light Survey Report 1. Introduction This report documents the obtrusive light impacts for the proposed South Bristol Link for defined lighting receptors identified in the desktop study and confirmed during the existing lighting survey. The impacts will be the net changes in obtrusive light over above those currently experienced by the lighting receptors Obtrusive Light criteria is outlined in the Institution of Lighting Professionals (ILP) guidance note on Obtrusive Lighting (ILP Guidance Note GN01:2011) and the SLL Guide To Limiting Obtrusive Light We have assumed that the proposed road cannot constitute a statutory nuisance under Clean Neighbourhoods and Environment Act 2005 if the proposed road lighting meets the recognised guidance, where there is doubt as to the proposed lighting meeting the guidance then mitigation methods have been recommended Purpose of the Lighting Impact Assessment The purpose of the Lighting Impact Assessment (LIA) is to provide an objective view of what the current baseline obtrusive light conditions are and to document them using a framework of objective criteria for planning permission. The LIA also forms an appendix of the overall Environmental Statement). Moreover, the LIA compares the existing baseline conditions (identified in the survey report (Appendix D)) with the proposed external lighting for the SBL. The LIA will also identify mitigation measures that can be adopted by the design team to reduce the obtrusive light impact of the new SBL lighting installations Obtrusive Light applied to Road Lighting Obtrusive light can be seen as external lighting that causes a loss of amenity for receptors. Road lighting is a defined example for the purposes of obtrusive light and has certain exemptions when compared to other external lighting installations. The criteria that apply to road lighting are: Skyglow Light Intrusion Luminaire luminance Sky glow is upward stray light from luminaires. The current design trends of road lighting luminaires is to have flat luminaires glass full cut-off luminaire column mounted with minimal tilt offering almost no upward light directly. These luminaires are a significant improvement on the older semi cut-off lanterns. There will be reflected upward light from road and surrounding ground surfaces and from passing vehicles as they move through the light distribution. This reflected upward light increases when conditions are wet from increased reflectance off wet surfaces and light scatter off raindrops. Passing light coloured vehicles will also give increased upward light. Reflected light is not considered by the published obtrusive light criteria due to variance in local conditions. Weather conditions are also not relevant. Light intrusion is stray light that is incident on windows. The light is measured as illuminance on the vertical face of the window. The light has to be direct light from the luminaire and not reflected light say off the vertical sides of light coloured vehicles. House side shields and good luminaire cut-off are the normal mitigation measures Luminaire luminance can be thought of as being the brightness of the luminaire against the ambient scene brightness. The luminaire luminance can be thought of as discomfort glare and would be intrusive to internal rooms if the recommend intensities are exceeded from normal observer positions. House side shields, reducing luminaire tilt and better luminaire cut-off are all accepted mitigation measures The SBL Site The SBL site extends from Long Ashton in the Northwest (in an L shape) to Cater Road roundabout at the east end. The area is semi-rural for the western half of the site and extends eastwards through a Atkins Obtrusive Light Survey Report Version January

6 South Bristol Link road Obtrusive Light Survey Report predominately suburban residential area. The SBL is not intended to be lit throughout its length. The road is lit at junctions and in the suburban and city areas Zoning of the Site The site was divided into twelve zones following the areas covered by the drawings. Each of the zones will be given an individual environmental classification. Each zone will be assessed against its individual receptor points as indicated in the desktop study (see appendix B) Environmental Classification Obtrusive lighting is assessed against a set of environmental lighting criteria based upon the level of background ambient light experienced in several types of environment. The table below details the criteria: Table 1. Environmental Zones Environmental Zones Zone Surrounding Lighting Examples Environment E0 Protected Dark UNESCO Starlight Reserves IDA Dark Sky Parks E1 Natural Intrinsically Dark National Parks Areas of Outstanding Natural Beauty, etc. E2 Rural Low district brightness Village or relatively dark outer suburban locations E3 Suburban Medium district brightness Small town centres and suburban locations E4 Urban High district brightness Town/City centres with high levels of night time activity.

8 South Bristol Link road Obtrusive Light Survey Report 2. LIA Methodology 2.1. Desktop Study A desktop study was undertaken at the inception of the project to ascertain the extent and position of obtrusive lighting receptors. The receptors referred to in this LIA are only considered from an obtrusive lighting requirement Choice of Receptor Points The LIA used the receptor points identified in the desktop study. Each receptor point was further refined by on site investigation. All recorded LIA points were located on public land. The receptor points were also restricted to ground level views. Views from first floor windows could not be taken although establishing whether first floor windows had a view of the site could be ascertained. on first floor window views are included in the results table. Illuminance readings were taken on the horizontal and vertical planes at a height of 1.5m above ground level. Luminance readings were taken of lamp sources contained within the view from eye level from the survey point Survey A lighting survey was undertaken in August 2012 to verify baseline obtrusive lighting conditions see (appendix C). The survey also verified the choice of receptors and took lighting criteria readings to be compared with the lighting criteria referred to in GN Survey Results Table The survey results table is located in (appendix C) at the rear of this document. The survey s prime purpose was to document in objective terms the baseline conditions at each survey point and to use photography to help with the documentation of the baseline conditions Reading the photographs The photographs are either single shots or photomontage panoramas to encompass a whole view. The photographs cannot be used as objective measuring tool and as such are included for guidance and identification purposes only. The night time photographs have used long time exposures and have in some cases been lightened in Photoshop to reveal details, therefore the overall brightness of the scene cannot taken as being realistic but the relative brightnesses in the scene can be seen as representative of what the camera sees Recommendations and Mitigation Techniques Recommendations The general recommendations of this report are the following:- Apply SLL and ILP guidance on obtrusive light. Use full cut-off road luminaires. Do not tilt the luminaires. Avoid high luminance light sources Do not over light the road. Use appropriate mounting heights (reduce the height of columns). Avoid drop glass Luminaires (pedestrian crossing lights can be difficult) Mitigation Reposition the luminaire if possible. Reduce height or tilt of luminaire Use outreach brackets if needed to obtain optimal positioning of the luminaire Atkins Obtrusive Light Survey Report Version January

10 South Bristol Link road Obtrusive Light Survey Report 3. SBL Recommendations & Mitigations by Site area 3.1. Recommendations for Obtrusive Lighting Effects of Construction and Final Proposed Road Lighting Construction Phase The lighting during the construction phase is likely to exhibit more obtrusive lighting impacts than the final proposed road lighting scheme. This is due to the temporary nature of the installation and the low levels of design normally undertaken for construction lighting. The lighting scheme is used for Health and Safety and/or site security. The best mitigation method is to propose a curfew on the site lighting during non-working hours with any security lighting on automatic detection control. All lighting should be full cut-off luminaire with no tilt above the horizontal plane and mounting heights reduced to a reasonable level of no more than 8m. It is recommended that at detailed implementation design stage for the lighting, check calculations are undertaken for light intrusion and Luminaire luminance for receptors as noted below. This will confirm the final design, once final fittings, columns etc have been selected, is in accord with this assessment Site Area 1 Ashton Court, Long Ashton & Yanley Commentary The lighting to the A370 Junction will have a relatively low impact on the current view from Ashton Court. The Universities hockey pitches are the largest single contributor to obtrusive light in the vista from the front facade of Ashton Court. The new luminaires at the A370 Junction will have lower light emissions than the existing drop glass class A road lanterns on the A370, so although there will be more luminaires the net effect of the junction should be less due to the better optical design of the luminaires. The Survey point references (SP No/No) refer to receptor points identified in the desktop study and survey report included in the appendices. Table 4.

12 South Bristol Link road Obtrusive Light Survey Report Site Area 3 Rose Meadow View Commentary The eastern row of static caravans on Rose Meadow View is likely to have views of the construction compound and the new lighting especially if the scrub trees to the west of the railway are to be removed during the groundwork stage. The proposed lighting will be visible to some caravans. Table 6.

13 South Bristol Link road Obtrusive Light Survey Report Site Area 6 A38 Junction The new junction is immediately to the North of Castle Farm. We do not believe the proposed lighting will cause significant obtrusive lighting issues for Castle Farm due to the distance between the lighting and farm buildings. Table 7.

Apply lighting curfew None Operation Castle Farm SP6/1 Non- Significant/ Negligible Apply GN01 guidelines and use full cut-off luminaires with no tilt None Undertake check calculations for light intrusion and Luminaire luminance for receptor point 6/1 and temporary points 6/2 and 6/ Site Area 7 Highridge Common Commentary The Highridge Common area will be a sensitive area due to the proximity of the properties on the common itself and the line of properties on Highridge Green. The properties to the east of the common on Highridge Road are unlikely to experience notable effects. The two properties on the common itself sit in a dark landscape and the new road will represent a change in their local environment, although the lighting only starts well to the east of the properties The height of the luminaires is 8m and there are a couple of isolated luminaires to the western end of the common; provided they are full cut-off flat glass, the impact will be non-significant. Undertake check calculations for Highridge House and Grove House for luminaire luminance SP7/6 SP7/7and check calculations for Light intrusion and luminaire luminance for Highridge green properties SP 7/3.

The properties are generally set back 10m from the road whilst the existing road lighting is located at the carriageway kerb edge. The proposed lighting scheme includes two lines of lighting columns, one at the pedestrian/cycle path and another at the carriageway kerb line. The heights of these luminaires are 4m and 8m respectively, the lamp source is LED. It is likely that none of the over viewing receptor points SP8/1-8/10 will have any obtrusive light issues due to the current high levels of obtrusive light evident in the baseline conditions (see survey report Appendix D). The residual effect of the proposed lighting will be better performing than the existing baseline semi cut-off luminaires due to the improved optical performance. Undertake check calculations to test the new positions especially for the cycle route lighting. Atkins Obtrusive Light Survey Report Version January

Moreover, the results of the survey demonstrated that the baseline conditions are well within those expected for each of the site areas and they conform to the Atkins Obtrusive Light Survey Report Version January

17 South Bristol Link road Obtrusive Light Survey Report environmental zoning criteria for obtrusive light as defined by the Institution of Lighting Professionals (ILP) - Guidance Note GN01. The environmental zoning criteria were chosen during the desktop study and none of the assumptions were changed as a result of the survey. In general, the levels of invasive light measured at the receptors from the existing installations are well within the guidance recommendations. The vertical illuminance values were taken at either the receptor positions or at the boundary with private lands. The survey also showed that in most cases there are few receptors that are likely to have obtrusive light issues with the current baseline conditions. The Ashton Vale end of the project is largely an E2 area, but any views from the south are affected heavily by the rising lands of Clifton and south Bristol generally in the background, which exhibit levels of light pollution and sky glow similar to a suburban (E3) or city (E4) area. The performance of the proposed lighting will be significantly better than the existing lighting due to changes in luminaire design and better lighting technology such as high performance reflectors and better light sources.

33 South Bristol Link Obtrusive Light Desktop Study 1. Introduction The purpose of this desktop study is to determine the obtrusive light implications for the South Bristol Link. The study will define the criteria, scope and receptors that are likely to be affected by the construction of the new road on the night time lit environment and will identify the scope of the Obtrusive Light Survey that will be conducted to determine the baseline situation and will be included as an appendix to the final report for inclusion in the Environmental Impact Assessment (EIA). This study is the first step in the process of identifying and evaluating obtrusive light problems and recommending mitigation measures to the design team for implementation in the final lighting design. The final report will form part of the EIA that will be used to address environmental impacts as part of the planning procedure for the project. The nature of the project and its site means that the baseline conditions change markedly depending upon the surrounding environs. This changing nature will mean that the obtrusive lighting criteria will also have to change to match the current site conditions. To accommodate the varying site conditions we propose to subdivide the site into subsections and apply the appropriate Environmental Light zoning to each of the area hence determine the obtrusive light criteria appropriate to each zone. Background to Obtrusive Light Legislation Obtrusive Light (formerly Light pollution) has been determined as a statutory nuisance under the terms of the Clean Neighbourhoods and Environment Act from 2005 in sections 101, 102 and 103 these sections are then enforced utilising sections 79,80, 81 and 82 of the Environmental Protection Act In the case of this project the lighting for this project does fall under the jurisdiction of the above legislation. 2. The Site The site is the proposed South Bristol Link road from the A 370 in Long Aston through to the Hengrove roundabout. The extent of the site is covered by the series of ten Pre Consultation Aerial Plans ref MMD C-DR-00-GA-0079 to MMD C-DR-00-GA-0089b. It is proposed to sub divide the site into site areas covered by each of the ten drawings Site Analysis by Site Area Site Area 1 A370 link In this site area the new road passes through open fields with small groups of trees at field boundaries. The new road is proposed to be lit via a single sided arrangement of street lanterns with dual sided junction arrangement for the new roundabout linking onto the A370. The proposed luminaires are likely to be full cut off lanterns mounted at a height of 8-12m. There are no residential properties in the immediate vicinity but there are possible views from both All Saints Church and Ashton Court Estate. These two sites have been highlighted as sites of significance and impacts on their night time environment should be assessed. The Long Ashton, Yanley and Westleaze and Wyke conservation areas have also been considered and preliminary receptor point allocated to these will be finalised during the survey Site Area 2 Ashton Vale Rapid Transit Link In this site area the road passes through open fields up to the industrial buildings adjacent to the proposed Brookgate stop. There are residential properties backing on to the line of the road to the East at about m distance. The park and ride car park may be a source of obtrusive light but it is a further 250m away from the residential properties. All Saints Church and Ashton Court have already been considered as part of area 1. Private and confidential Atkins Obtrusive Light Desktop study Version July 2012

34 South Bristol Link Obtrusive Light Desktop Study Site Area 3 Brookgate Stop In this site area the two link roads combine to form a single new road. There appears to be no residential properties in the area of the stop and junction with an industrial estate immediately to the east of the junction. We assess this area to have no receptors at present; this will be confirmed by the survey Site Area 4 South of Railway/Colliters Brook In this site area the road passes through open fields. There is no lighting on this section of the road south of the railway bridge hence no impact Site Area 5 Hanging Hill Wood/ A38 Junction In this site area the road passes through open fields to the east of Hanging Hill Wood. There is junction street lighting to cover the intersection with the A38. The only receptor appears to be a farm to Northeast of the junction at about 500m from the road. The farm house appears to have a gable end facing the junction Site Area 6 A38 Junction/Castle Farm In this site area the road passes through open fields as the new road crosses the east-west running A38. The only receptor is likely to be Castle Farm to the southwest of the Junction Site Area 7 Highridge Green Road In this site area the road leaves the open fields and enters an area of residential housing. The houses are generally set back between 3-15m from the kerb line of the adjoining road Highridge Green Road and get increasingly closer to the line of the new road as the road merge. The new lighting starts at the junction of Highridge Green Road and the SBL scheme Site Area 8 Highridge Road In this site area the road is passing through the last of open land to the southwest of the junction with Highridge Road. to the southeast of the junction the road passes through a residential estate on land set aside for this development. There are residential properties on both sides of King Georges Road. The residential properties run parallel to the scheme through to the junction with Queens Road. The distance between these properties and kerb line of the new road will mean that these properties are considered as receptors. Additional receptors have been added for possible views for The Malago and Bishopsworth Conservation Areas although it is not clear at the moment whether these areas will have views of the new road Site Area 9 Queens Road In this site area the road passes a school and some commercial buildings before continuing through the residential properties. This will effectively mean it is likely only the gable ends of the properties and the front and rear faces of the last properties on each side of the road need to be considered as receptors. The school is set back from the road and will probably be unaffected. The school will be a receptor at present but maybe dropped during the survey, likewise the commercial properties Site Area 10 Hareclive Road In this site area the road continues to pass through residential properties on both sides up to the intersection with Hareclive Rd. East of the intersection the residential properties are only to the southern side of the new road. The residential properties stop at the Cater Rd Intersection. 3. Obtrusive Light 3.1. The Receptors The receptors have been identified as the residential buildings backing on to the proposed road. The receptors chosen are our inital assessment of the receptor points required to document the baseline levels of obtrusive the receptors also include local Heritage assets and Conservation areas identified by the letter from English Heritage (see appendix 1). The adjacent industrial buildings can largely be ignored as they are Private and confidential Atkins Obtrusive Light Desktop study Version July 2012

35 South Bristol Link Obtrusive Light Desktop Study unlikely to be occupied during the hours of darkness. Industrial buildings are not normally considered as receptors as disturbance to sleep is considered the prime nuisance. This assumption will be confirmed by the survey. Any specialised buildings such as farm buildings that could be sensitive to disturbance from light will be identified through the survey. The receptors have been initially identified on the marked up drawings (located in appendix C) Environmental Zoning. The nature of the site changes through the each of the ten site areas. we have applied an environmental Zone for each area as follows:- Table 1. Project Obtrusive Light Environmental Zoning according to ILP GN01 Site Area Environmental Zone Surrounding Lighting Environment 01 E2 Rural Low District Brightness 02 E2 Rural Low District Brightness 03 E2 Rural Low District Brightness 04 E2 Rural Low District Brightness 05 E2 Rural Low District Brightness 06 E2 Rural Low District Brightness 07 E3 Suburban Medium District Brightness 08 E3 Suburban Medium District Brightness 09 E3 Suburban Medium District Brightness 10 E4 Urban High District Brightness Example Village or Relatively dark outer Suburban Area Village or Relatively dark outer Suburban Area Village or Relatively dark outer Suburban Area Village or Relatively dark outer Suburban Area Village or Relatively dark outer Suburban Area Village or Relatively dark outer Suburban Area Small town centres or suburban areas Small town centres or suburban areas Small town centres or suburban areas Town/city centres with high levels of night time activity 3.3. Local Regulations. The site lies within the jurisdiction of the two local authorities of North Somerset and the City of Bristol. We have visited their planning portals to establish any local requirements after the survey. To date we can find no specific local planning recommendations regarding obtrusive light that would affect this site. We would therefore suggest that the guidance given by the ILP (Institution of Lighting Engineers) would form the basis of demonstrating compliance with obtrusive lighting criteria. Private and confidential Atkins Obtrusive Light Desktop study Version July 2012

36 South Bristol Link Obtrusive Light Desktop Study 3.4. Possible effects. The receptors can be subject to four effects of obtrusive light:- Light Intrusion- Light entering windows Measured in illuminance lux (E v.) Luminaire Intensity- Glare emitted by unshielded light sources in the direction of the observer, measured in (Cd/m 2 ). Building luminance- Pre-Curfew the brightness of building facades in the direction of the viewer, measured in (Cd/m 2 ). Light Trespass- light entering the boundaries of adjacent properties measured in Lux (E h ) at the boundary of the site. This value should not exceed 1 lux at the site boundary. Light Intrusion, Luminaire Intensity and Light Trespass are likely to be the effects identified by the baseline survey Obtrusive Light Criteria Table 2.

The Survey The purpose of the survey is to ascertain the current situation with regard to obtrusive light that exists on site before works commence. The survey will identify through readings of Iuminance and illuminance the current situation. Up to five photographs will be taken at each point of reference identified on the Lighting Impact Assessment drawing (Located in appendix B). The survey will also check and inform the final report and will correct any inconsistencies/ assumptions in this study. Additional receptor points maybe added as a result of the daytime survey The proposed date of the survey is the 15 th- 16 th August 2012 and will be conducted in the afternoon and early evening 1 hour after sunset Access Limitations. The survey will be limited to public rights of way and carriageways no attempt will be made to enter private property to take readings or take photographs. The drawing shows the intended measurement positions and these positions maybe altered to suit access restrictions Measurement Method The readings will be taken with calibrated measurement equipment and readings will be taken from the boundary of the receptor site or at positions which are as adjacent as possible to the marked point.

46 Guidance Notes for the Reduction of Obtrusive Light GN01:2011 GUIDANCE NOTES FOR THE REDUCTION OF OBTRUSIVE LIGHT Think before you light - The right amount of light, where wanted, when wanted. Man's invention of artificial light has done much to safeguard and enhance our night-time environment but, if not properly controlled, obtrusive light (sometimes referred to as light pollution) can present serious physiological and ecological problems. Obtrusive Light, whether it keeps you awake through a bedroom window or impedes your view of the night sky, is a form of pollution, which may also be a nuisance in law and which can be substantially reduced without detriment to the lighting task. Sky glow, the brightening of the night sky, Glare the uncomfortable brightness of a light source when viewed against a darker background, and Light Intrusion ( Trespass ), the spilling of light beyond the boundary of the property or area being lit, are all forms of obtrusive light which may cause nuisance to others and waste money and energy. Think before you light. Is it necessary? What effect will it have on others? Will it cause a nuisance? How can you minimise the problem? Figure 1 Types of obtrusive light Do not "over" light. This is a major cause of obtrusive light and is a waste of energy. There are published standards for most lighting tasks, adherence to which will help minimise upward reflected light. Organisations from which full details of these standards can be obtained are given on the last page of this leaflet. 1

47 Guidance Notes for the Reduction of Obtrusive Light GN01:2011 Dim or switch off lights when the task is finished. Generally a lower level of lighting will suffice to enhance the night time scene than that required for safety and security. Good Design equals Good Lighting Any lighting scheme will consist of three basic elements: a light source, a luminaire and a method of installation. Light sources (Lamps) Remember that the light source output in LUMENS is not the same as the wattage and that it is the former that is important in combating the problems of obtrusive light. Most nightime visual tasks are only dependant on light radiated within the visual spectrum. It is therefore NOT necessary for light sources to emit either ultra-violet or infra-red radiation unless specifically designed to do so. It is also understood that light from the shorter wavelengths of the spectrum has important effects on both flora and fauna that should be considered. Research indicates that light from the blue end of the spectrum has important non-visual effects on the health of the human body, in particular in our sleep/wake patterns. It is therefore important to appreciate that while in obtrusive light terms the use of blue light should be minimised, there are many night-time tasks such as driving and sports where to be fully awake is an important aid to safety. Luminaires Care should always be taken when selecting luminaires to ensure that appropriate products are chosen and that their location will reduce spill light and glare to a minimum. Use specifically designed lighting equipment that minimises the upward spread of light near to and above the horizontal. The most sensitive/critical zones for minimising sky glow are those between 90 o and 100 o as shown in Figure 2 and referred to as the lower, upward light output zone (UL). Figure 2 Critical luminaire angles For minimising sky glow 2

48 Guidance Notes for the Reduction of Obtrusive Light GN01:2011 For most sports and area lighting installations the use of luminaires with doubleasymmetric beams designed so that the front glazing is kept at or near parallel to the surface being lit should, if correctly aimed, ensures minimum obtrusive light. Appendices 1 and 2 to these notes gives more details of how to choose and if necessary modify luminaires. Installation In most cases it will be beneficial to use as high a mounting height as possible, giving due regard to the daytime appearance of the installation. The requirements to control glare for the safety of road users are given in Table 3. Keep glare to a minimum by ensuring that the main beam angle of all lights directed towards any potential observer is not more than 70 o. Higher mounting heights allow lower main beam angles, which can assist in reducing glare. In areas with low ambient lighting levels, glare can be very obtrusive and extra care should be taken when positioning and aiming lighting equipment. With regard to domestic security lighting the ILP produces an information leaflet GN02:2009 that is freely available from its website. Figure 3 Luminare aiming angles Poor Okay Good When lighting vertical structures such as advertising signs, direct light downwards wherever possible. If there is no alternative to up-lighting, as with much decorative lighting of buildings, then the use of shields, baffles and louvres will help reduce spill light around and over the structure to a minimum. For road and amenity lighting installations, (see also design standards listed on Page 5) light near to and above the horizontal should normally be minimised to reduce glare and sky glow (Note ULR s in Table 2). In rural areas the use of full horizontal cut off luminaires installed at 0 o uplift will, in addition to reducing sky glow, also help to minimise visual intrusion within the open landscape. However in some urban locations, luminaires fitted with a more decorative bowl and good optical control of light should be acceptable and may be more appropriate. 3

49 Guidance Notes for the Reduction of Obtrusive Light GN01:2011 Figure 4 Façade Illumination Poor Good Good Since 2006 Artificial Light has been added to the list of possible Statutory Nuisances in England, Wales and Scotland. The monitoring of such nuisances will be the responsibility of Environmental Health Officers (EHOs) for which separate guidance is being produced. With regard to the planning aspect, many Local Planning Authorities (LPAs) have already produced, or are producing, policies that within the planning system will become part of their local development framework. For new developments there is an opportunity for LPAs to impose planning conditions related to external lighting, including curfew hours. The Scottish Executive has published a design methodology document (March 2007) entitled Controlling Light Pollution and Reducing Energy Consumption to further assist in mitigating obtrusive light elements at the design stage. ENVIRONMENTAL ZONES It is recommended that Local Planning Authorities specify the following environmental zones for exterior lighting control within their Development Plans. Table 1 Environmental Zones Zone Surrounding Lighting Examples Environment E0 Protected Dark UNESCO Starlight Reserves, IDA Dark Sky Parks E1 Natural Intrinsically dark National Parks, Areas of Outstanding Natural Beauty etc E2 Rural Low district brightness Village or relatively dark outer suburban locations E3 Suburban Medium district brightness Small town centres or suburban locations E4 Urban High district brightness Town/city centres with high levels of nighttime activity 4

50 Guidance Notes for the Reduction of Obtrusive Light GN01:2011 Where an area to be lit lies on the boundary of two zones the obtrusive light limitation values used should be those applicable to the most rigorous zone. NB: Zone E0 must always be surrounded by an E1 Zone. DESIGN GUIDANCE The following limitations may be supplemented or replaced by a LPA s own planning guidance for exterior lighting installations. As lighting design is not as simple as it may seem, you are advised to consult and/or work with a professional lighting designer before installing any exterior lighting.

However, care should always be taken to minimise any upward waste light by the proper application of suitably directional luminaires and light controlling attachments. 5

51 Guidance Notes for the Reduction of Obtrusive Light GN01:2011 (2) Light Intrusion (into Windows) These values are suggested maxima and need to take account of existing light intrusion at the point of measurement. In the case of road lighting on public highways where building facades are adjacent to the lit highway, these levels may not be obtainable. In such cases where a specific complaint has been received, the Highway Authority should endeavour to reduce the light intrusion into the window down to the post curfew value by fitting a shield, replacing the luminaire, or by varying the lighting level. (3) Luminaire Intensity This applies to each luminaire in the potentially obtrusive direction, outside of the area being lit. The figures given are for general guidance only and for some sports lighting applications with limited mounting heights, may be difficult to achieve. (4) Building Luminance This should be limited to avoid over lighting, and related to the general district brightness. In this reference building luminance is applicable to buildings directly illuminated as a night-time feature as against the illumination of a building caused by spill light from adjacent luminaires or luminaires fixed to the building but used to light an adjacent area.
