We adopted the Development at Gatwick Airport Supplementary Planning Document (SPD) on 17 December 2008. Gatwick Airport is one of the most important developments within the borough. Its influence and impact extends far beyond the borough boundary into the wider sub-region in terms of its environmental, social and economic impacts. The SPD has been prepared to provide guidance on the way in which we will implement our policies in dealing with planning applications, consultations and other planning matters at Gatwick Airport.
