Hong Kong to spend HK$300 million on flood-control steps to protect from megastorms

Hong Kong authorities have expressed confidence they can better handle extreme weather events in the coming decades as they outlined strategies and upgrades to infrastructure worth more than HK$300 million (US$38.3 million) that will bolster defences against heavy rainfall, rising sea levels and storm surges.

They were also planning to take steps at 11 more areas such as the vicinity of the Kwun Tong Ferry Pier and Tseung Kwan O Industrial Area, to bolster resilience against flooding. A government source said on Friday authorities were 'confident' such measures would help areas to withstand megastorms on the level of super typhoons Hato and Mangkhut in 2017 and 2018, as well as the downpour in 2023 that caused heavy flooding across the city and was described as a 'once-in-500-years' event. 28:31 Hong Kong flooded by 'once-in-a-century' rainstorm Hong Kong flooded by 'once-in-a-century' rainstorm The Drainage Services Department (DSD) and Civil Engineering and Development Department (CEDD) completed two studies in late 2024: one on flood management and strategies in response to rising sea levels and extreme rainfall, and another on coastal management.
