were constructed at a cost of S$1 million. In January 1977, plans to build a aquatic centre to complement the lagoon were announced. The Singapore Tennis Centre, located in the park, was opened in March that year. Plans for a 1200-seat food centre near the lagoon were announced in April, and the first batch of the Housing and Urban Development Company's (HUDC) chalets were opened in May, with the rest following soon after. Plans for a seafood centre in the park, with five seafood restaurants from Upper East Coast Road, were also announced that year. The $6 million aquatic centre, named 'Big Splash', was opened in July 1977. It featured an slide, which was claimed to be the world's longest and highest, and an artificial wave pool, as well as food outlets. Nevertheless, the aquatic centre suffered from poor business and low patronage, and cost $2 million a year to operate. As a result, the original operator sold it to the Singapore Industrial Business Organisation (SILO) for $4.3 million the following year. In August 1978, the Parkland Golf Driving Range, the first one in Singapore, opened its doors in the park. Due to high demand for the chalets, the Urban Redevelopment Authority constructed 59 additional two-storey chalets, twice as large as the previous ones, for the HUDC in 1979. Costing $2.5 million, the chalets were opened in April 1981. The 1980s and 1990s In 1980, as part of the government's desire to inculcate a sense of courtesy among road users, a , $1 million traffic games park for children, operated by the Traffic Police, was built. A sailing school was opened by the Singapore Sports Council off the lagoon in May that year. The cycling track was also extended from the lagoon to Changi Point and the entire East Coast area was landscaped as parkland over two years beginning in 1981, to cope with the large number of users. The East Coast Recreation Centre, built at a cost of $3.5 million, opened in 1982, with restaurants, a computer library, sports facilities, and a remote-control car track. During this period, the park also had insufficient parking spaces to cope with demand, resulting in widespread illegal parking in the more popular areas. Hence, more parking spaces were built, and the government put in place parking fees to encourage motorists to use other, less utilised carparks. To facilitate crime prevention and public outreach,
