Australia-based CX Landscape has unveiled designs for Sea Line Park, a conceptual project to link the eastern and western inner suburbs of Melbourne with a linear coastal park. Designed to serve as a new line of defense against rising waters, the Sea Line Park would comprise three islands, two pontoon bridges and undersea roads to provide a new direct connection between Williams Town to the west and Elwood in the east. The fantastical proposal would also draw power from renewable sources, including tidal and solar power.

Bookended by two movable pontoon bridges, the Sea Line Park consists of three curvaceous green islands: two “Sports Islands” flanking a central “Art Island”. The Sports Islands would function as public outdoor recreation space for both active and passive programs. The Art Island serves primarily as an events space and would be home to a large north-facing meadow that can host open cinemas, performances, markets and other events. A naturalistic landscape with pedestrian and cyclist paths would be integrated onto all islands.

The linear parks would also house a live seed bank within a series of pods, the design of which is inspired by the diamond-patterned totem polls of the Wurundjeri tribe. Solar panels would cover the exterior of each pod and — along with the tidal power generation units integrated in the two pontoon bridges — provide energy for the entire park. The islands are also punctuated by bubble-like structures that house seawater purification and freshwater storage systems.

To address ocean waste, the designers have proposed using submarine robots to collect plastic ocean debris and repurposing the waste as raw material for 3D printing construction materials. “This park will grow, adapt and innovate with the help of cutting-edge technologies, to be resilient and resistant to natural disasters and climate change,” the designers said. “A self-sustained living hub is suitable for any coastal cities around the world, which can carry the critical resources and civilizations to create a mobile global village.”
