Officer report
What officers recommended
Officers recommended approval, finding that the changes would not create unacceptable landscape, ecological, heritage, amenity, safety or transport effects and could be controlled by conditions.
“The DNS decision found that the Environmental Statement assessed the impact of the proposal on heritage assets and their settings, including the buried archaeological remains. It concluded that the proposal would have moderate (significant) adverse effects on the setting of Caerphilly Castle and Llanbradach Fawr and its associated listed barn and range. The effects on other heritage assets, after mitigation, would be at most minor and not significant.”
“The DNS decision found that the appropriate control measures could be put in place through imposition of planning conditions to ensure that noise impacts and shadow flicker would be controlled and would be within acceptable levels. It is noted that in respect of shadow flicker it is anticipated that due to the increase in rotor diameter additional properties could be affected by shadow flicker.”
