North CBD Cakung is a projects that designed to fullfil the needs of the community of residence and work space. Located in Kelurahan Rorotan, Kecamatan Cilincing, North Jakarta, North CBD Cakung will built to superblock area and has various facilities such as housing, malls, apartments, hotels, education and health facilities and offices. Built on an area of 36 hectares. The changing of land use due to the development causes the infiltration rainwater into the soil to be reduced and increasing the amount of runoff. The condition of ground tend to be flat and high rainfall intensity can cause potentially flooding. One solution to overcome the increase of rainwater runoff and as a flood prevention effort, North CBD Cakung area requires drainage system. Planning drainage system is done by survey the existing condition of the area and the receiving water body. A hydrologic analysis of 10-year rainfall data was conducted to see the frequency characteristics, duration and intensity of rainfall of North CBD Cakung. It is also to obtain the flood discharge plan which is the basis for calculating the dimensions of drainage and other complementary structures. The planning retention pond that serves to hold water while from the drainage channel of North CBD Cakung Area to then be channeled to the water body that is the Kali Tiram. The intensity of rain used rainfall in the 5 year re-period for tertiary channels, 10 years for secondary channels, and <br /> <br /> 25 years for primary channels. The result of the hydrologic analysis shows the rainfall period of 5th return period; 10; and 25 years are respectively 189.79 mm / day; 237,74 mm / day; and 311.12 mm / day. The drainage channel is planned to be <br /> <br /> 4440 meters long, rectangular with 23 channels and 696 street inlets. <br /> <br />
