Abstract:
Following Parts 1 and 2 of the study from the sociology and visionary development points of view of the new seashore city to be built in the southern of Coloane and Hangqin island in the reclaimed land in the shallow bay area, this Part is to explore the possible engineering solutions to make the dream comes true. In Macau the new 16 sq.km city is an island set at 1~2 km from the Hacsa Bay, whereas the 16 sq.km new city in Zhuhai is a peninsula of Hangqin. Simple engineering works are all it needs to check the muddy water flows in the bay at low tides, but not the sea water during high tides – therefore the muddy water should stay away from the bay and the water quality is improved. The plan cannot be implemented without the cooperation of Zhuhai and the blessing of the Central Government and the Guangdong Authority. The purpose of this study is to scheme the infrastructure, including expressway, bridge, tunnel and deep water port for the new city Zhuhai at the same time is benefited from the development as it could share the deep water port and own an expressway connecting Zhuhai west to the Hong Kong-Zhuhai-Macau landing. The plan also shows the possible way of developing Huang Mao Island into an international cruiser terminal, a nature deep water port on the west side of the Pearl River Delta. An ocean park is also possible. The island is linked to the new city by a sea-crossing bridge. Finally, the construction cost is estimated using the completed similar projects in China as a guide. The estimated cost is around 40~60 Billion. Assuming 25% of the land with a plot ratio of 5 is set for sale for development right. Based on the current market value the sale proceeds can be as much as 300~360 Billion. This would make the whole project self financed. As long as the environmental mitigation measures being implemented correctly, the project is second to none and is highly recommended.
