Singapore’s most ambitious infrastructure undertaking in a generation took a concrete step forward on 30 June 2026, when the Urban Redevelopment Authority (URA) and the Housing & Development Board (HDB) announced that preparatory works for ‘Long Island’ — the Government’s large-scale coastal protection strategy for the East Coast — will commence from end-2026. For property owners, investors, and anyone watching the long arc of Singapore’s planning, this announcement sets a firm starting gun on a project that will reshape the East Coast’s future land supply, flood resilience, and lifestyle amenities over the next several decades.

‘Long Island’ is not simply a reclamation project — it is Singapore’s primary response to the threat of rising sea levels to its low-lying East Coast. The Government has long signalled that without proactive intervention, the East Coast’s beaches, parks, and existing development would become increasingly vulnerable as global sea levels rise. Long Island will ultimately create a new landmass off the East Coast, incorporating a reservoir, an expanded coastal park, and mixed-use development land — but that is decades away. What changes now is that the ground work begins.

What Are the Preparatory Works — and Why Now?

The preparatory works announced on 30 June 2026 are a precursor to the main reclamation. They involve three primary activities: removal of seabed obstructions (existing cables, pipelines, and debris), construction of temporary sand bunds (underwater embankments to contain the work area), and sand infilling to begin building up the seabed. These are engineering prerequisites — the seabed must be cleared and stabilised before full-scale reclamation can proceed.

The timing reflects two pressures. First, the Government has identified that sea level rise poses an increasingly urgent risk to the East Coast, and delaying the preparatory works extends the timeline for protection. Second, the 2029 SEA Games — to be hosted partly at East Coast Park — limits when Phase 2 can begin. By starting Phase 1 now and phasing Phase 2 to avoid disrupting the Games, the Government has threaded the needle between urgency and community impact.

The preparatory works will take place at least 130 metres from the shoreline and will be demarcated by silt screens and floating barriers. HDB, as the appointed reclamation agent, will monitor water quality, sediment levels, noise, and dust throughout.

Environmental Impact — What the Study Found

HDB commissioned an Environmental Study specifically for the preparatory works phase. The study’s key findings provide important context for how the works will affect the surrounding environment:

On water quality: no significant changes are expected. Water quality will continue to meet prevailing marine water quality criteria throughout the works. Silt screens will contain sediment plumes.

On marine biodiversity: there is up to minor impact on some coral and seagrass beds near the works site, with potential short-term and localised effects from sediment plumes. The majority of coral and seagrass in the vicinity — including Sisters’ Islands Marine Park — are assessed to be largely unaffected. This will reassure the nature community, which had concerns about the proximity of Phase 1 to some of the East Coast’s more ecologically sensitive zones.

On sea sports: kiteboarding will be the most affected activity, with moderate displacement from the reduced sea space. Other sea sport users face minor to moderate impact. Agencies have committed to working with affected sea sport users to find alternative sites for the interim period.

The Environmental Study report is open for public feedback for four weeks from 30 June 2026. An Environmental Monitoring and Management Plan (EMMP) will be put in place to manage environmental conditions throughout the works.

What This Means for East Coast Property

Long Island will be one of the most significant drivers of East Coast property values over the coming decade — but it is a slow-burn catalyst rather than an immediate price mover. Here is the framework LovelyHomes uses to think about the property implications:

Short term (2026–2030): Neutral to slightly negative. The preparatory works bring marine vessels, sand infilling activity, and restricted sea space off the East Coast. Buyers considering East Coast properties — particularly those with sea-facing units or sea-sports lifestyle utility — should factor in construction-adjacent disruption. This is unlikely to cause price falls (East Coast fundamentals remain strong), but it may dampen the marginal premium that sea-view units command during this period.

Medium term (2030s): Watch for planning signals. When the detailed reclamation plans are released — expected after the technical studies are completed in the early 2030s — the market will get clarity on the eventual land profile, the new waterfront layout, the reservoir location, and potential residential zones. This is when the property market will begin to price in the Long Island uplift meaningfully. Marine Parade, Bedok, and Siglap properties in particular may benefit from the signal that the East Coast will gain a significant new green and waterfront amenity.

Long term (2040s and beyond): Transformative. If Long Island proceeds as currently envisaged — a new coastal park, a freshwater reservoir, and new urban land — it represents the creation of entirely new prime East Coast real estate. The precedent is Bishan, which was built on former agricultural land and is now one of Singapore’s most sought-after mature estates. Long Island’s eventual waterfront development could command premium valuations similar to the Marina Bay waterfront, which today represents some of Singapore’s highest residential and commercial values.

Long Island in Context — Singapore’s Coastal Planning History

This is not the first time Singapore has reclaimed land to address long-term needs. Marina Bay itself was reclaimed over several decades — the land that now hosts Marina Bay Sands, the financial district, and Gardens by the Bay was once open sea. Jurong Island was created by amalgamating seven smaller islands for petrochemical use. Changi Airport’s runways sit on reclaimed land. What is different about Long Island is its explicit dual purpose: it is simultaneously a climate adaptation measure (coastal protection) and a land creation exercise — and it is being planned with unusually extensive public engagement, reflecting a more consultative planning era.

The Government’s message is clear: Long Island is going ahead, and it will be built in a way that is sensitive to the environment, the existing East Coast community, and the interests of future residents. For property investors, that certainty has real value — it means the East Coast’s long-term trajectory is upward.

Frequently Asked Questions

Will Long Island be built for housing? When will new homes be available?

The Government has said Long Island will include new urban land — but has not yet confirmed the mix of residential, commercial, industrial, or recreational uses. Given the project timeline, any new housing on Long Island is at least 20–30 years away. The more immediate property implication is the uplift to existing East Coast properties as the project progresses and its final scope becomes clear. The Government’s track record — Marina Bay, Bidadari — suggests Long Island’s eventual homes will be well-planned and high-quality, but buyers looking for a near-term supply injection from this project will be disappointed.

Does the Long Island announcement affect East Coast Park access?

No. URA and HDB have explicitly confirmed that beaches, jogging and cycling paths, and near-shore swimming areas along East Coast Park will remain open and accessible throughout the preparatory works. Works are at least 130 metres from the shoreline. The main restriction is on certain sea sports users — particularly kiteboarding — who will need to use alternative sea space during the Phase 1 period. East Coast Park itself, as a recreational asset, is unaffected.

Will the preparatory works affect sea views from East Coast condominiums?

In the near term, marine vessels, sand bunds, and floating barriers will be visible from East Coast properties with sea views — particularly during active infilling operations. However, these are temporary structures for the preparatory phase. The visual impact during preparatory works is expected to be significant from units with direct sea views but modest from properties further back. The more important long-term consideration is that once Long Island is reclaimed, those “sea view” units may have their sightlines altered permanently — a factor that discerning buyers of high-floor sea-facing East Coast units should factor into their purchase decision today.

How does this compare to Singapore’s previous reclamation projects?

Long Island is comparable in scale to the Tuas reclamation (which expanded Singapore’s western coast for industrial use) and the Changi East reclamation (which expanded Changi Airport). In terms of residential property impact, the closest precedent is Marina Bay — which transformed from open sea to the city’s premier commercial and residential address. Long Island’s combination of climate resilience purpose and mixed-use development potential makes it perhaps the most strategically significant reclamation in Singapore since Marina Bay, with a potentially larger impact on the East Coast residential market than any single policy change in recent memory.
