A vast slice of coastal land will be freed up once the ports move from Pasir Panjang and Tanjong Pagar to Tuas by 2027.

Some ideas have already emerged from government planners for the 1,000-hectare area that will be known as the Greater Southern Waterfront.

These range from erecting a barrage around Pulau Brani to form another reservoir and network of streetside canals, to creating a single continuous waterfront promenade that snakes around the coast.

Other ideas include creating several waterfront districts from Labrador to Marina South, each with its own unique character.

These could include varied styles of housing, island living on Pulau Brani, and piers and marinas.

Green corridors of open space links Mount Faber to Pulau Brani are a possibility, as is extending a central linear park in Marina Bay to the waterfront.

The central business district and nearby housing could be extended to the waterfront as well.

The government wants the public to contribute ideas for the new waterfront area too.
