Singapore has taken a decisive step in its long-term climate adaptation strategy with the introduction of the Coastal Protection Bill, legislation designed to safeguard the nation’s low-lying coastline against rising sea levels and more extreme weather.
Tabled for First Reading in Parliament on February 3, the Bill establishes, for the first time, a comprehensive legal framework that defines who is responsible for coastal protection, how those measures must perform, and how continuity of defence will be enforced across the island.
As a city-state where around 30 per cent of land sits less than five metres above mean sea level, coastal flooding is no longer treated as a distant risk. Instead, it is being addressed as a system-wide infrastructure challenge that requires decades of coordinated planning, construction, and maintenance.

Clear responsibilities for a shared coastline
At the centre of the Bill is a requirement that landowners, including government agencies, statutory boards, and long-term lessees, implement coastal protection measures for their respective land parcels. These measures must meet national standards and connect seamlessly with neighbouring defences, ensuring there are no weak points along the shoreline.
Singapore’s Minister for Sustainability and the Environment has positioned the legislation as a necessary response to fragmented protection outcomes that can undermine even well-designed assets.
“The Bill safeguards Singapore’s coastline against rising sea levels and extreme weather events by establishing clear responsibilities of landowners for coastal protection and ensuring compliance with coastal protection standards,” the Ministry said in its introduction of the legislation.
The Government already owns around 70 per cent of Singapore’s coastline and will continue to deliver most major coastal protection works. However, the remaining privately occupied sections are critical to the integrity of the overall system, particularly during storm surges and high tide events.
Long lead times to support delivery
Recognising the scale and technical complexity of coastal defence infrastructure, the Bill provides landowners with at least 10 years’ advance notice before protection measures must be implemented. Timelines will be aligned with detailed, site-specific coastal studies that have been progressively underway since 2021.
This approach is intended to give industry, consultants and asset owners sufficient lead time to plan, design and integrate coastal protection works alongside redevelopment or renewal programs.
“Coastal protection is a long-term endeavour which requires years of planning and construction,” the Ministry noted. “The Bill is tabled now to give landowners and the industry sufficient notice and lead time to be familiar with the requirements.”
Regulation, oversight and operational accountability
Beyond construction, the legislation places strong emphasis on the long-term performance of coastal protection assets. Once completed, measures will be recorded in a national Coastal Protection Interpretation Plan, a digital platform that documents location, design and connectivity.
Landowners will be required to inspect, maintain and repair their assets over time, notify authorities of damage, and appoint designated flood protection managers where required. PUB will retain regulatory oversight powers to approve works, manage interfaces between adjacent land parcels, and enforce compliance when standards are not met.
The Bill also introduces the concept of Transiently Floodable Areas, such as beaches and coastal parks, allowing public access to remain while requiring flood response planning for temporary inundation during extreme events.
Support alongside enforcement
While the framework introduces penalties for non-compliance, the Government has emphasised that financial and technical support will be provided to help landowners meet minimum standards. Details of this support package are expected to be released as the legislation progresses.
Stakeholder engagement has already played a role in shaping the Bill, with waterfront industries consulted during its development. Further engagement is expected as the legislation moves toward its Second Reading in March 2026.
Taken together, the Coastal Protection Bill signals a shift from coastal adaptation as a policy aspiration to coastal protection as regulated national infrastructure, embedded into planning, development and asset management decisions for decades to come.
