Prince Abdulmajeed, as Head of the Makkah Development Authority, also announced plans to establish in the central zone of the Holy City multi-storey car parks, public transport terminals, and pedestrian walkways. Plans are also under way, he said, to establish a joint stock company to develop the Jabal Omar area close to the Grand Mosque. He gave assurances that these, and other planned projects, would be implemented without affecting Makkah's hydro-geology and topography, especially the sources of zamzam water.
