Contract Awarded for ‘Typhoon-Proof’ Shenzhen Coast
KCAP + FELIXX have won the international competition for the redevelopment of the 130-kilometer coastline of Dapeng, a green peninsula in the bay between Hong Kong and Shenzhen.
In September 2018, the typhoon Mangkhut damaged the infrastructure of the peninsula to various degrees.
An international competition was launched to develop a plan to restore the coastline and raise protection standards against the more frequent occurrence of extreme weather events.
KCAP+FELIXX developed the ‘Triple dike strategy’, a multifaceted dike system that allows for an integrated approach towards the climate adaptive reorganization of the shore.
For 32 kilometers of coastline, the contractor is developing this concept into six strategic implementation projects. Realization starts this year, and is expected to be completed in 2021.
The triple dike moves away from a generic protection wall along the coast, towards the creation of three development zones, carefully embedded in current conditions and responding to the specific future needs of every single area.
The 1st ‘outer’ dike zone increases the resiliency through wave attenuation, erosion reduction and the enhancement of sedimentation.
The 2nd ‘middle’ dike is an elevated embankment, to stop the storm surge and the water pushed up by the waves. It’s not a big wall but a multifunctional zone: an exciting hilly park, an elevated waterfront with urban promenades, a tidal park or even a public building.
The 3rd ‘inner’ dike is a hybrid structure which manages the rainwater following the principle of a sponge city.
