 Apia proper is just a small village between the mouths of the Vaisigano (east) and Mulivai (west) rivers, and is framed by Vaisigano and Mulivai villages, together constituting "Downtown Apia".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.
