“Typhoon-proof” is more than just a phrase here at Shenzhen’s Typhoon Shelter. It is a design philosophy. This area stands as a testament to Shenzhen’s commitment to resilience in the face of extreme weather.
The Typhoon Shelter has become more important, especially after the devastation of Typhoon Mangkhut. This catastrophic cyclone caused extensive damage in 2018. It highlighted the urgent need for better coastal protection.
The city launched an international competition. The goal was to develop a plan to restore the coastline. It also aimed to raise protection standards against frequent extreme weather events.
KCAP+FELIXX developed the ‘Triple Dike Strategy’. It is a multifaceted dike system for climate adaptation. This strategy connects water safety with ecological development. It also promotes nature restoration. This resilient framework supports social and economic growth in the area. The implementation started in 2019 and was expected to finish in 2021.
The Triple Dike moves away from a generic protection wall. It creates three development zones. These zones are embedded in current conditions. They respond to the future needs of each area.
The first ‘outer’ dike zone increases resilience. It does this through wave attenuation. It reduces erosion. It enhances sedimentation.
The second ‘middle’ dike is an elevated embankment. It stops storm surges and wave water. It is a multifunctional zone. It could be a hilly park. It could be an elevated waterfront with urban promenades. It might even be a public building.
The third ‘inner’ dike is a hybrid structure. It manages rainwater following the principle of a sponge city. Runoff from villages and mountains is buffered. It is delayed. It is temporarily stored in rain parks and wetlands.
Dapeng Peninsula is near Shenzhen. It is a mountainous area with lush forests. Riverbeds and creeks intersect it. It connects to the sea with sand beaches and rockeries. Small fishing villages dot the shore. Tourism has developed here. The Triple Dike enhances existing qualities. It unlocks potential for growth.
The villages’ small-scale identity is protected. New developments stay within existing boundaries. Each village’s specific character is strengthened. This amplifies the rich variation of recreational facilities. Water connectivity is enhanced to minimize the infrastructural impact. An interconnected mountain and marine landscape boosts the ecological functioning of the peninsula.
The Xichong Coastal Reserve is another part of Shenzhen’s typhoon defense. It enhances the seaside getaway experience. It protects local ecosystems. It supports ecological tourism.
The Coastal Reserve restores natural water flows. It repairs eroded river corridors. It restores wetlands and coastal mangrove habitats. This provides tourist experiences. Boardwalks, kayaking routes, and floating markets appear. Flood-proof residences respond to the river system.
The project’s coastal defense strategy mitigates floods and typhoons. It reinstates dune systems. Cafes and restaurants are built within the reconstructed dune-scapes. They connect with sheltered beach walks and camping areas. A new dike hybridizes engineering and natural landscapes. It protects against flooding and high seas.
Most urban expansion focuses around four existing villages. Xigong Town expands along a restored stream. Shagang Town grows around new terraced orchards. Hesou Town is upgraded with a central civic street. Xinwu Town develops around a new health retreat.
Shenzhen’s Typhoon Shelter represents a blend of engineering. It is a natural beauty. It is a testament to human resilience. It is a commitment to sustainable development in the face of nature’s power.
