The Application Site is located within an E1 Environmental Zone, because it is within the South Downs National Park and within the South Downs International Dark Sky Reserve 2km Buffer Zone.
The Desktop Study that we performed, showed us that the northern, eastern and western boundaries of the Application Site were areas with potentially sensitive wildlife. As such the “worst-case scenario” is assumed and DFL refer to the guidance in GN08/2023 to avoid potential harm to the areas. It was highly likely that those ecological receptors would be sensitive to light, even more likely that they would be commuting/ foraging bats
We advised that the proposed development of four houses would require lighting for safety and amenity at limited times during the hours of darkness. This lighting needed to be fit for purpose and sensitive to nearby human and ecological receptors.
As always with areas such as this, a warm white colour temperature light is recommended and one that would only distribute light downwards, to avoid potential light spill to the surrounding buildings and upwards to the sky.
Wall lanterns were recommended to be no greater than 2 metres from the ground and should use proximity sensors, only switching on for 1 minute when presence is detected.
