Table 5-2: Summary of important features along the route of the distribution line (Original Table 15) Sl. No.ParameterDescription1Ecologically Critical AreaNo Ecologically critical areas were foundReserve/ProtectedNo reserve or protected forests area were found2Predominant Geological FormationsDhaka is situated at the southern tip of a Pleistocene terrace of the Madhupur Tract. Two characteristic geological units cover the city and surroundings, the Madhupur clay of the Pleistocene age and alluvial deposits of recent age.TopographyMost of the area has an elevation of four to six meters. The highest elevation was observed in the northern part of the area. The lowest elevation was observed in the western part along the side of the Balu River.Major Physiographic UnitsThe area falls into Physiographic unit of Madhupur Tract. It comprises central part of Dhaka the course of Brahmaputra –Jamuna Floodplain.Major Soil TypeThe soil in mainly of red Coloured and mottled clays. Soils in the valleys are dark general belongs to a Pleistocene terrace consisting grey heavy clays. They are strongly acidic in reaction with low status of organic matter, low moisture holding capacity and low fertility level.3Principal cropsLike other cities of Bangladesh, agriculture is important in parts of urban fringe of the Dhaka city. Rice is the most important crop.Wheat and potatoes are also important. Others agricultural products include fruits, in particular mango, banana and pineapple.4Major Water BodiesZone-1 Shegunbagicha KhalZone-2 Dholai Khal, Zirani-Nandipara khal, Manda Khal, DND Khal, Balu River, Shitalakshya RiverZone-3 Khilgoan-basaboo khal, Zirani khal, Balu River, Shitalakshya River5FloodingThe area is more prone to flood than the other area of Dhaka city. The area is generally flooded by the ingress from the backwater flow of the Dhaleswari, Meghna Rivers, Shitalakshya and Balu Rivers.6SeismicityThe project area falls in the earthquake Zone-2 of the seismic map of Bangladesh. This zone refers medium intensity of seismic effects7Environmental HotspotsZone-1 School (11 nos.), Madrasha (10 nos.), College (5 nos.), University (2 nos.) Baitul Mokarram Masjid, Mosque (51 nos.)
