peoples. Before the 1960s, Bedok's primary source of income was coconut, which was harvested from the plantations found in the Siglap subzone. Fishing was another primary source of income for the villagers of Simpang Bedok at the time. The modern development of Bedok only began in 1966, when reclamation works along the coastal area began. In the following decade, Bedok was transformed by the Housing and Development Board (HDB) into the country's fifth self-contained new town, with the first residential flats emerging in the vicinity by 1975. Following the Fall of Saigon that same year, Bedok Jetty became a focal point for Vietnamese refugees landing in Singapore during Operation Thunderstorm. Bedok Town had been developed since 1973, with the newer roads such as Bedok Plain, Bedok Highway, and Bedok Heights being built until 1975. The New Upper Changi Road was fully built and opened in 1979, where the massive development had been completed except Bedok Reservoir and Kaki Bukit, which was built later between 1983 and 1988. Geography Location Bedok Planning Area is located within the East Region of Singapore, along Pulau Ujong's southeastern coast. It is bounded by Paya Lebar to the north, Hougang to the northwest, Tampines to the northeast and east, Geylang to the west, and Marine Parade to the southwest. Bedok New Town sits within the Bedok Planning Area. Subzones Bedok is divided into 8 subzones: Infrastructure Bedok New Town covers a land area close to with some 42% occupied for residential use. It was formerly a hilly region, and hence the focal point of orientation of the town is the special landscaped park and sports complex built on the higher ground of the town. The residential blocks, as well as the industrial area, are planned based on the neighbourhood concept. There is also a town centre situated between the present Bedok Mall and the former Bedok Point site. Plans for an integrated complex, which will be as big as three football fields, have also been revealed in 2014. This complex, Heartbeat @ Bedok, houses a sports centre, library, clinic, centre for the elderly, and the Kampong Chai Chee Community Club. The complex is located in the Bedok Town centre and was completed in 2017. Residential development Some 58,000 units of flats were built by the HDB in Bedok New Town. As one of the older towns, the majority of the flats are 3-room or 4-room.
