Tomorrow's Lantau | Twice the depth of reclamation in Sanpao. Our research institute is worried about the construction cost as if it is a bottomless pond, and urges to explain the buried unit price

The Development Bureau submitted a document to the Legislative Council today (20th), disclosing the latest plan for "Lantau Tomorrow", which involves reclaiming the sea around Kau Yi Chau in the central waters to build artificial islands, at a cost of 580 billion yuan.

According to the local research institute, the water depth of the reclamation area of ​​the "Lantau Tomorrow" artificial island is deeper than that of the third runway of the airport and the artificial island of the Hong Kong-Zhuhai-Macao Port, and is even twice as deep as the third runway of the airport. It is worried that the uncertainty of deep-water reclamation technology will It may cause overspending, or even reproduce the "drift" situation of the artificial island at the Hong Kong-Zhuhai-Macao Port.

The Native Research Institute also mentioned that if the Hong Kong government continues to use the cost of similar projects to estimate the cost of artificial islands, it is not a fantasy that the three major artificial islands in Kau Yi Chau will be greatly underestimated. They urge the Hong Kong government to clearly explain the ultimate "payment price" of the plan.

There may be a serious underestimation of the construction cost or even the "drift" of the artificial island of the bridge

Local research groups who are concerned about the "Lantau Tomorrow" plan are worried that if the Hong Kong government continues to use the cost of similar projects to estimate the cost of artificial islands, or there will be serious underestimation, it will not be a fantasy for the three major artificial islands to have a large cost underestimation, and the authorities It is planned to finalize reclamation in a deeper water area. Due to the instability of technology, it is possible to further overrun the project, or even reproduce the "drift" situation of the artificial island at the Hong Kong Port of the Hong Kong-Zhuhai-Macao Bridge.

According to the research document of the artificial island in the central waters of the Development Bureau, the authorities suggested reclamation in relatively shallow waters, so they chose to reclaim the sea at an average depth of about 8 meters in the north, west and south, while the east where the water is relatively deep (about 12 meters deep) to 15 meters), avoid reclamation.

The artificial island in the central waters is filled with an average depth of 8 meters. The airport runs only 3 to 4 meters in three runs.

The Native Research Institute stated that if the water depth of similar reclamation projects is compared with Hong Kong's nautical charts, the artificial island of Lantau tomorrow will be "deeper than the sea".

The Native Research Institute continued that the average water depth of the reclamation area of ​​the airport during the third run was 3 to 4 meters, and the artificial island of the Hong Kong-Zhuhai-Macao Port, which is known for its "non-dredging" reclamation and causing "drift", averaged a depth of 2 to 5 meters. However, for the larger artificial islands, the average depth of site selection is 6 to 8 meters, which is twice as deep as the previous three runs. In some reclamation areas near the East Lama Strait (or the western buffer zone), the water depth is even deeper Up to 9 to 10 meters.

Indigenous research institutes mentioned that more instabilities, overruns, and various additional costs will be generated in technology for reclamation in deeper water. Hengkong is located in the central waters of Hong Kong, which has narrowed the east-west distance of the entire central waters channel by 3 points and 1, and the project scope will be filled into the deep and fast-flowing East Lamma Channel, which will have an incalculable impact on the water flow.

Subsequent investigations with reference to large-scale reclamation projects in other areas have shown that the water flow in some adjacent areas may be accelerated, leading to coastal erosion and habitat changes, or the water flow in some adjacent areas may be slowed down, resulting in seabed siltation or salinization. become an ecological dead zone.

The Local Research Institute questioned that the public consultation on "Lantau Tomorrow" is about to start. If there is no clear account of the cost of the project, how will the citizens weigh the trade-offs.
