Surat: At a time when the Airports Authority of India (AAI) is pushing for the parallel runway at Surat airport, the real estate players want the government to drop the proposal on the grounds that it will hamper development of new commercial and residential projects in the vicinity. Realtors said that about 198 buildings are identified as obstructions and the new projects are facing building height restriction due to the existing runway. The parallel runway will further restrict the growth of the real estate projects in key areas of Surat, which is forecast to be the 9th fastest growing city in the world by World Economic Forum (WEF).
