Defending Southeast Singapore Against Rising Seas: Proposed Strategies Include Coastal Barriers and Shoreline Enhancements

In a recent statement, Deputy Prime Minister and Minister for Trade and Industry, Gan Kim Yong, emphasised the importance of protecting Singapore's coastlines. He highlighted that the coastal protection efforts are of existential importance due to the country's lack of options to "retreat" inland.

The coastal protection measures, which include the construction of barriers and retrofits to existing structures, are scheduled to begin in the 2030s. The region encompassing these projects is vast, stretching from the Greater Southern Waterfront, East Coast, and Changi.

Mr. Gan compared coastal protection to long-term endeavours like public housing, water, and infrastructure, positioning it as a necessary investment in the safety, security, and resilience of the nation. He stated that the task is complex and will take decades to complete.

One of the key features of the coastal protection plan is the use of setback measures at Changi Beach Park. This approach aims to preserve beach access and minimise impact on biodiversity.

Another notable initiative is the planned "Long Island" for East Coast, announced in 2023. This project will create an enclosed waterbody in front of East Coast Park, acting as a barricade against erosion in the mainland.

In addition to these measures, retrofits to the Marina Barrage and raised coastal protection structures are also part of the plan. To ensure the success of these projects, PUB, along with relevant government agencies, will conduct detailed studies to develop engineering designs and conduct environmental impact assessments.

The coastal protection site-specific study for the City-East Coast region started in 2021 and cost S$18 million (US$14 million). The planning and construction of these measures are mainly aimed at addressing rising sea levels and climate change impacts that threaten these low-lying coastal areas.

The coastal protection efforts at East Coast complement the ones in Greater Southern Waterfront and Changi. These initiatives are all interconnected, linking Sentosa, Pulau Brani, and the mainland with the proposed coastal barriers.

In conclusion, the coastal protection measures in Singapore's City-East Coast region are a significant long-term investment in the safety and resilience of the nation. The projects, which include the "Long Island" initiative and retrofits to the Marina Barrage, aim to address the challenges posed by rising sea levels and climate change. The planning and construction of these measures are scheduled to begin in the 2030s.
