千金補「島」鑊?

港珠澳大橋人工島呈現的問題,為香港曾引以為傲的城市建設及規劃能力響起警號。

首先,負責大橋規劃的人沒有與香港機場預先協商加設連接道路,令大橋旅客無法直達機場禁區,變相要前後過關兩次。補鑊:我們現在要以更高成本興建通道以作補救措施。

其次,人工島與屯赤連接路的工程師沒有或忘記互相通知工程更動,兩個路段規劃因而出現衝突。補鑊:以成本高昂且複雜的工程改動屯赤連接路的走線。

第三,撇除各個多年來屢屢問及的問題,當局一直沒有計劃如何使用人工島、 道路及跨境設施周邊的土地,大樓、停車場等空間運用亦從來沒有定案。有趣的是,香港現正缺乏土地,而我們卻碰巧是(或曾經是)多用途建築的專家。補鑊:以成本效益低盡用人工島的空間。

這種治標不治本、缺乏整體規劃且經常需要穿湊附合的做法亦可見於九龍。由荔枝角走到西九文化區,最後一片維港填海土地都充斥着大而無當的交通基建,與城市中的戰壕無異。

在啟德,啟德發展中心及起動九龍東辦事處正盡最大努力減低規劃及工程不當的影響,相信未來會為整個地區帶來有價值的改變。然而,以上都無法掩飾一些令人震驚的城市規劃。規模過大且選址錯誤的啟德遊輪碼頭只是冰山一角(倒不如把固定的設施及間隔移除,將其改做成會議及展覽場地,並在有需要時才加設簡單的過境及登船設施)。此外,跑道中央旁邊道路上的大型隔音牆仿如一個擴音器,對未來落成樓宇的窗戶牆壁日夜轟炸,噪音繼而反射至道路另一旁的建築,繼而進入跑道周邊的行人路網絡,多美好的社區亦只能盡數枯萎。市民亦會對了無生氣的啟德海濱大感失望,並要下一代為我們的錯補鑊,現在我們只能祈求體育城及四邊道路會為當區帶來一絲生機。

提出這些問題,是因為我們要在開展另一項大型城市規劃前吸取教訓並修正做法,新界的新市鎮是其中之一,人工島等的大型基建及補救措施同樣如是。

現時的工程及規劃缺乏遠見,亦缺乏動力創造更好的成果,以致工程主導的痕跡隨處可見,突兀的基建一個又一個,破壞社區原來的面貌。土地及上蓋空間低效運用、以大型人工島及跨境大橋破壞眾多海洋生物棲息地等,這些代價絕對不能接受,一眾專業人士亦難辭其咎。

 

The island of costly retrofits

The planning and engineering failures at the boundary crossing island are a big red flag indicating how Hong Kong's ability to plan and engineer our city smartly has been lost.

First, the road guys designed the island without talking with the airport. As a result there was no link which would allow passengers to stay ‘airside’ and travel between the airport and the pearl river delta without having to go through immigration twice. Retrofit: A dedicated road will be added at great cost.

Second, the different engineers of the island and the Tuen Mun tunnel link forgot to update each other and got their interfaces wrong. Retrofit: A difficult and costly adjustment of the Tuen Mun Tunnel alignment.

Third, despite many questions over many years, the island, roads and cross border facilities have been completed without a plan for the use of the remaining land and the use of the airspace above the flat buildings, parking and holding areas. That in a city where we are short of land and where we used to be experts in multi-use structures. Retrofit: Trying to squeeze in land uses, structures and properties at great cost and with little efficiency.

This sequential planning without an overall master plan and constant retrofitting can also be seen in Kowloon. From Lai Chi Kok down to the West Kowloon Cultural District the outcome is an urban war zone on the largest of our last reclamations in Victoria Harbour with an oversized footprint of transport infrastructure.

At Kai Tak the Kai Tak Development Office and the Energizing Kowloon East Office are trying to coordinate as hard as they can to limit the damage of our faulty planning and engineering processes. Their hard work will show some good urban outcomes, but there again will be some shocking urban features. The over sized single use cruise terminal in the wrong place in the city is one we all know already (please rip out the furniture and partition walls and use it as a conferencing and exhibition space, and roll out  simple 'pop-up systems for immigration and boarding facilities only when needed).

The next one people will slowly become aware of in Kai Tak is the gigantic noise cover over the road along the middle of the runway which will act as a megaphone blasting the road noise against the walls and windows of future buildings on one side which will bounce the noise to the buildings on the other side of the road. The noise cover will impede pedestrian connectivity across the runway and blight what should have been a beautiful new district. People will also be disappointed with a stale waterfront along the Kai Tak Approach Channel, and future generations will have to figure out retrofits. Fingers crossed as to how the sports stadium and roads around it will interface with the surroundings.

I'm raising these issues because we need to learn and adjust before we embark on massive new urban developments - the New Development Areas in the New Territories and huge new islands, including massive and intrusive infrastructure retrofits.

Our current planning and engineering processes lack visions and motivation for great urban outcomes; lead to massive over engineering, with outlandish and intrusive footprints of infrastructure; result in inefficient land and air rights uses; blight our seas and marine habitats with a massive island of roads and Boundary Crossing Facility and little else to show for. Our professionals need a huge kick in the butt. It is simply unacceptable.
