Geography
It has an area of 16.94 square kilometres, and is located northeast of Kuala Lumpur. The surface is relatively high; 500 metres above sea level, and the topography here is highland, lowland, or undulating land. As a result, it is a rain catchment area for the Klang River. Among the high locations are Bukit Antarabangsa, Bukit Kemensah, and Bukit Belacan. The hill is composed of limestone, which is brittle and dissolves during heavy rains. As a result, several landslides have occurred in this area, forcing people mainly living in flats, as well as some houses on the hillside, to evacuate. A notable incident is the collapse of Highland Towers in 1993. Moreover, the flow of the Klang River was straightened in several places, which caused water to flow faster, leading Kuala Lumpur to experience flash floods on June 10, 2007.Public facilities
Many factories, housing estates, and tourist attractions have been built. A notable factory is Texas Instrument, and the DBP warehouse can also be found here. Zoo Negara has forests which are typically explored and developed, which has affected the environment. Other strategic places include waterfalls in Bukit Belacan and Hulu Kemensah, as well as a trail from Kemensah to the top of Gunung Nuang in Hulu Langat for mountain climbers.List of residential areas
