KCAP + FELIXX win competition to redevelop shoreline defences

KCAP + FELIXX have won an international competition for the redevelopment of 130 km coastline in Dapeng, a green peninsula situated in the bay between Hong Kong and Shenzhen. The contest was launched to restore local infrastructure damaged by a typhoon in 2018, and to raise protection standards against future extreme weather events. The winning design proposes a ‘triple dike strategy’,  establishing an integrated approach towards reorganizing the shore while also stimulating social and economic growth.

The triple dike moves away from the usual idea of a single protective wall stretching along the coast, towards the creation of three development zones responding to the specific needs of each area. An outer dike zone increases resiliency through reducing wave power and erosion. The middle dike is an elevated embankment to prevent storm surges, while also offering possible functions as a park, an elevated waterfront with urban promenades, a tidal park or even a public building. The third dike is a hybrid structure which manages rainwater runoff from the nearby villages and mountains, storing the water in raingardens, wet forests, wetlands and green streets.

As a mountainous peninsula with lush forests and sandy beaches, Dapeng has seen an increase in tourism. Along the shore, several small villages have grown up from fishing communities. The application of the triple-dike provides a framework to enhance the area’s natural and cultural heritage while unlocking potentials for growth. The small-scale identity of the villages is protected by locating new developments within existing boundaries and creating new recreational opportunities.
