 The Planning Urban Management Authority (PUMA) Act 2004 (amended in 2005) was passed by parliament to better plan for the urban growth of Samoa's built-up areas, with particular reference to the future urban management of Apia.The city's historical haphazard growth from village to colonial trading post to the major financial and business centre of the country has resulted in major infrastructural problems in the city.Problems of flooding are commonplace in the wet season, given the low flood-prone valley that the city is built on.
