There are an average of 3 floodlights on each column and 6 columns in total. These excessively bright floodlights are very poorly focused causing a lot of glare and stray light of which spills over into the surrounding receptors. The multi-storey accommodation blocks to the south of the stablings (Receptor 1 & 2 ) are newly built and construction are still taking place around the area. It could therefore be assumed that most of the lighting to the stablings was there before these newly developed apartments. Separating these highly sensitive receptors from the stablings we have an access road with parking bays and a 2 metre high wooden wall all outside Crossrail boundaries. The access road is illuminated using 4 metre column mounted high pressure sodium street lights, some of these street lights are shining directly into the windows of the ground floor apartments. Generally the houses to the north (Receptor 4 & 5) are facing away from the stablings but are still greatly affected by these poorly focussed flood lights spilling light into their back gardens and windows.

Baseline Lit EffectA. The existing GEML stabling sidings are illuminated using high pressure sodium floodlights mounted on approximately 18 metre columns. There are an average of 3 floodlights on each column and
6 columns in total. These excessively bright floodlights are very poorly focused causing a lot of glare and stray light of which spills over into the surrounding receptors.
The multi-storey accommodation blocks to the south of the stablings (Receptor 1 & 2 ) are newly built and construction are still taking place around the area. It could therefore be assumed that most of the lighting to the stablings was there before these newly developed apartments. Separating these highly sensitive receptors from the stablings we have an access road with parking bays and a 2 metre high wooden wall all outside Crossrail boundaries. The access road is illuminated using 4 metre column mounted high pressure sodium street lights, some of these street lights are shining directly into the windows of the ground floor apartments.
Generally the houses to the north (Receptor 4 & 5) are facing away from the stablings but are still greatly affected by these poorly focussed flood lights spilling light into their back gardens and windows.

Detail Assessment Pro-formaSite Location
Receptor Location 1 – Residents – Coopers Court and Tallis CourtBaseline; The high-rise residences (3 storeys) currently view Area A, railway and sidings are brightly illuminated using high mast High Pressure sodium floodlights. The existing lighting is poorly directed and controlled.
During Construction; A solid 6 ft wooden fence separates the receptor from Area A, clear views particularly from the upper storeys will impact upon receptors. Ambient illumination levels, therefore sky glow and visual brightness will be increased. Hoarding is unlikely to sufficiently shield views into the site. Accurate direction, aiming and localised shielding of fixtures may aid in limiting spill light, glare and direct views of lamp sources above, hoarding level. However, given the close proximity to Area A and multiple sight lines, glare may be seen at some viewing locations. As the site is operational 24/7 for the track, the duration of the impact is extended. As the design of the existing lighting installation is poor the suggested impact is ‘NOT SIGNIFICANT’.
During Operation; The baseline railway and sidings will be re-instated at Area A. At a minimum the impact upon receptors will be equal to the current installation, the suggested impact is ‘NOT SIGNIFICANT’. If a new lighting scheme, designed in accordance with key guidance publications, is installed the impact may improve to ‘SIGNIFICANT BENEFICIAL’.
Receptor Location 2 – Residents – Elves Ave (Under development)Baseline; 2 Storeys currently view Area A, railway and sidings are brightly illuminated using high mast High Pressure sodium floodlights. The existing lighting is poorly directed and controlled.
During Construction; Site lights associated with the overnight works to the existing GEML railway and sidings will impact upon the receptors. A solid 6 ft wooden fence separates the receptor from Area A, clear views particularly from the upper storeys will impact upon receptors. Ambient illumination levels, therefore sky glow and visual brightness will be increased. Hoarding is unlikely to sufficiently shield views into the site.

If a new lighting scheme, designed in accordance with key guidance publications, is installed the impact may improve to ‘SIGNIFICANT BENEFICIAL’.
Receptor Location 3 – Residents – Ashlyn Grove/Stafford AveBaseline; Residential housing currently view Area A, railway and sidings are brightly illuminated using high mast High Pressure sodium floodlights. The existing lighting is poorly directed and controlled.
During Construction; Site lights associated with the overnight works to the existing GEML railway and sidings will impact upon the receptors. An embankment separates the receptor from Area A. Ambient illumination levels, therefore sky glow and visual brightness will be increased. Hoarding is unlikely to sufficiently shield views into the site. Accurate direction, aiming and localised shielding of fixtures may aid in limiting spill light, glare and direct views of lamp sources above, hoarding level.

Receptor Location 4 – Residents – Amery/GardensBaseline; Residential housing currently view Area A, railway and brightly illuminated using high mast High Pressure sodium floodlights. The existing lighting is poorly directed and controlled.
During Construction; Site lights associated with the overnight works to the existing GEML railway and sidings will impact upon the receptors. Ambient illumination levels, therefore sky glow and visual brightness will be increased. Hoarding is likely to sufficiently shield views into the site.

If a new lighting scheme, designed in accordance with key guidance publications, is installed the impact may improve to ‘SIGNIFICANT BENEFICIAL’.
Receptor Location 5 – Residents – Upper Brentwood/Cambridge AvenueBaseline; Residential housing currently view Area A, railway brightly illuminated using high mast High Pressure sodium floodlights.The existing lighting is poorly directed and controlled.
During Construction; Site lights associated with the overnight works to the existing GEML railway and sidings will impact upon the receptors exacerbated as the railway is at a lower level than the adjacent land. Ambient illumination levels, therefore sky glow and visual brightness will be increased. Hoarding is unlikely to sufficiently shield views into the site. Accurate direction, aiming and localised shielding of fixtures may aid in limiting spill light, glare and direct views of lamp sources above hoarding level. However, given the close proximity to Area A and multiple sight lines, glare may be seen at some viewing locations. As the site is operational 24/7 for the track, the duration of the impact is extended. As the design of the existing lighting installation is poor the suggested impact is ‘NOT SIGNIFICANT’.
During Operation; The baseline railway and sidings will be re-instated at Area A. At a minimum the impact upon receptors will be equal to the current installation, the suggested impact is ‘NOT SIGNIFICANT’. If a new lighting scheme, designed in accordance with key guidance publications, is installed the impact may improve to ‘SIGNIFICANT BENEFICIAL’.
Receptor Location 6 – Train DriversBaseline; Train drivers navigate an a brightly illuminated railway and sidings ,Area A, brightly illuminated using high mast High Pressure sodium floodlights. The existing lighting is poorly directed and controlled.
During Construction; Due to the elevated location of the track the train drivers will have unobstructed views into the construction sites. Ambient illumination levels, therefore sky glow and visual brightness will be increased. Mitigated by the use of hoarding may be ineffectual as a result of these good site lines. Accurate direction, aiming and localised shielding of fixtures may aid in limiting spill light, glare and direct views of lamp sources above hoarding level. However, given the close proximity to Area A and multiple sight lines, glare may be seen at some viewing locations. As the site is operational 24/7 for the track, the duration of the impact is extended. As the design of the existing lighting installation is poor the suggested impact is ‘NOT SIGNIFICANT’.
During Operation; The baseline railway and sidings should be re-instated at Area A and as a result no impact upon receptors. At a minimum the impact upon receptors will be equal to the current installation, the suggested impact is ‘NOT SIGNIFICANT’. If a new lighting scheme, designed in accordance with key guidance publications, is installed the impact may improve to ‘SIGNIFICANT BENEFICIAL’.
