In the form of a continuous meandering line, the Kai Tak Nullah serves an ever expanding role and key resource that connects and reconnects neighborhoods, businesses, and people. With its rich woodland walks and memorable parks, the Kai Tak Nullah becomes a meandering ecological spine dedicated to connection, recreation, and regeneration. All components of the system from the headwaters at Diamond Hill to the Estuary at Kai Tak Approach are part of an overall restorative design strategy to improve the Healthy Riverside way of life.
OBJECTIVES AND CHALLENGES
Objectives: The objective of the linear park design was to create Healthy Riverside Living through a Green River Corridor, accommodating connection and recreational activities, educating the public about green technologies, and transforming a unique space to make the Kai Tak River an integral part of the community.
Challenges: The first challenge is restoring and transforming the degraded environment along the Kai Tak Nullah into a safe and pleasant public space. The shoulders of the Nullah are currently narrow and inhospitable to pedestrian travel. The water of Kai Tak River is highly polluted with a national water quality ranking of Lower Grade V, the lowest grade on a scale of I–V and is considered unsafe for swimming and recreation and devoid of aquatic life. The second challenge is to create a contiguous pedestrian cum cyclist trail system that extends from the planned Diamond Hill Comprehensive Development Area (DHCDA) to the Estuary Promenade at the Kai Tak Approach
Channel (KTAC). The third challenge was the site itself with many vehicle bridges, flyovers, desilting compounds, and other infrastructure improvements.
Nature is the most resilient system and has forms that are self‐regenerating. Prior to the formation of the Kai Tak Bund residential district in the 1920’s a number of streams wound through the Kai Tak region towards the sea. When water passes over the face of an object the natural forces form a braided geometry along its surface. This braided geometry of the river form is adapted in this project as a network of circulation, connecting north to south and east to west, with a system of secondary connectors bringing people from the residential districts together in a common thread. Our design has taken the river bed geometry as our inspiration to create a New Water Urbanism Landscape that will provide the residents of Kai Tak a greater community experience, while retaining the singularity of the landscape language throughout Kai Tak River.
ICON IN NATURE
As the estuary is restored for natural habitats and a place of learning, it also creates an opportunity for an iconic architectural element that captures the imagination of this park system, as well as affords a spectacular view towards Kai Tak waterfront, and the forever mesmerizing Hong Kong skyline. Our architecture takes shape from our braided geometry, rising approximately 28‐30 meters from the Sea’s surface, in the form of a large frame. The frame becomes a water screen on occasion, adding to the vibrancy of the art and culture of Hong Kong to this distinctive district with a giant water wall and digital effects. This frame serves as a beacon for change, hope, and vision. And is truly alandmark symbol in the midst of a resilient ecological system of the Estuary.
SOCIAL ENVIRONMENT: WATER URBANISM
The creation of the Kai Tak Green River Corridor and Estuary provides an indelible opportunity to reconnect neighbors and neighborhoods. In the busy and bustling Kai Tak development where art and culture will be rich and larger crowds dispersed at the environmentally friendly light rail station, we envision the area along the Kai Tak River to be tranquil, green, and a splendor of natural beauty. Along this meandering river course, a variety of programs are offered to reinvigorate activity and connection. A primary pathway for both cycle and pedestrian meanders through the park system from Headwater to Estuary and serves as the primary route of travel and connection to the surrounding city. Secondary pathways are utilized to integrate and pull people in from surrounding neighborhoods to circulate throughout the park. This network ensures seamless connections between the park and its surroundings, accommodates peak pedestrian flows, and ensures a pleasant and accessible public park experience at the human scale. A variety of terraces and raised platforms provide viewing, relaxing, and socializing options. Terraces and pathways with an elevation difference between the community and the river, safely reconnect people to the water’s edge.
LIVING SYSTEM: RETURN THE EXPERIENCE OF NATURE
By increasing awareness and connection to nature, this Green River Corridor project can begin to heal the riverfront. The ecological services of this park system in the environs of the Estuary shall include: storm‐water/sea‐water treatment strategies in the form of salt marshes, constructed wetlands, and vernal ponds. Improving the quality of water from storm water runoff is essential to the improvement of urban ecosystems along the waterfront. Well designed treatment train systems can help minimize the generation, mobilization and transport of common storm water pollutants and watershed‐specific pollutants. Groves of trees act as screens along the paths to break up spaces andprovide natural habitat. Other ecological services would include food production, plant selection to maximize bio‐diversity, and the creation of wildlife habitats.
Through an aesthetically natural river form, our design envisions a restorative transformation of the Kai Tak Nullah into a tranquil riverside social environment and living system that showcases cultural heritage and offers comprehensive ecological services. As a new Urban Oasis this corridor can become an integral part of a Healthy City strategy.
To RESPECT the current river channel that is proposed by the Engineers for treating the water and not disturbs its performance.
To ADAPT forms of nature, in this case the riverbed braided geometry to organize the framework of the two sides of river from diamond hill site down to the estuary
To ACTIVATE the two riverbank side by creating a series of programmes through manipulating the ground and provide an variety of experience of vistas and spaces Through out, both along the riverside and creating pocketed spaces within the park.
To CONNECT existing Choi Hung Estate, Diamond Hill neighborhoods and proposed.Future Kai Tak development area by providing a continuous pathway that runs north to south, and connection points to encourage access from adjacent neighborhoods.
