I can't find much about Pasir Ris. It is just a mangrove belt.
Sg Api-Api and Sg Tampines used to converge before being discharged
into sea. The sandy soils contained coconut trees, and there were
numerous fish ponds in the vicinity.
In the 1970s, Elias Road linked Tampines Road to the area, where
Pasir Ris Hotel stood at the end of it. Malay villages were
concentrated on the coast and estuaries, while Chinese settlements
were dotted along Elias Road.
Planning for Pasir Ris Town started in the mid-1970's and was
initially unveiled in Concept Plan 1978 as a high-density
residential area, designed to be "picturesque, with a resort-like
ambience and a distinctive character."
The current land use development plan for the town was conceived in
the 1985 Master Plan, with a large utility and agritechnology zone
planned near Lorong Halus.
In 1992, a draft plan for DGP tried to incorporate a more
sea-oriented scheme. All new towns then lacked a close link between
the residential areas and the sea. This plan for sea edge housing,
marinas and a coastal road was, however, discarded in the 1995 land
use plan as it required the complete destruction of Pasir Ris Park,
which was deemed too costly to implement. Seaside housing is,
however, taking into consideration for future new town
developments, like Punggol and Simpang.
Pasir Ris 21 Plan was unveiled in December 1996 at a cost of $20
million, which resulted in Pasir Ris West Plaza, Elias Mall, Pasir
Ris CC and dedicated cycling paths.
