Lighting Impact Assessments

Stainton Lighting Design Services (SLDS) can provide lighting impact assessments / environmental impact assessments for inclusion within planning and strategy documentation.

Our team can carry out site assessments to determine the extents of obtrusive light and light nuisance and build results from site measurement into any documentation. Through our design software we can also assess proposed column positions and their affect on the landscape and surrounding environment and provide robust lighting pollution mitigation measures in line with the Institution of Lighting Professionals (ILP) guidance for obtrusive light.

Light pollution was introduced within the Clean Neighbourhoods and Environmental Act in 2005 with the inclusion of "artificial light emitted from premises so as to be prejudicial to health or a nuisance". As a form of statutory nuisance under the Environmental Protection Act since the introduction of the act, exterior lighting impact assessments are becoming more commonly requested for planning applications, particularly those falling under EIA development.

Although light was described within the act as having the potential to cause statutory nuisance, no prescriptive limits or rules were set for assessment. The guidance notes for the Reduction of Obtrusive Light produced by the ILP, however, is commonly adopted in the UK for suitable lighting assessment criteria.

SLDS have a proven track record of understanding, analysing, determining and mitigating environmental impacts across a wide range of exterior lighting projects, and can produce comprehensive reports to accommodate any size or type of exterior lighting projects and planning requirements, typically reports will include some or all of the following items:

Desktop Study - We undertake a desktop study of the project and other available information, to determine existing lighting in the vicinity. This would provide the baseline impact of any existing lighting, the Ecological and Environmental considerations and general site topography. This would focus around key viewpoints and relevant receptors.

Inspection - Site daytime and night-time inspection, including baseline photographic images for mitigation. Additionally, for larger projects we may undertake and map on-site baseline lighting level measurements to determine the impact of any existing lighting.

Specification - We would provide specification, methodologies and conclusion's to ensure impacts are mitigated. This will often cover switching regimes, dynamic lighting levels, curfews, lighting equipment specification, mounting heights, appropriate lighting levels and colour temperatures.
