Senayan Park is a lifestyle center located in Central Jakarta. Senayan Park is a revitalization of Taman Ria Senayan and aims to advance the community's economy and increase the fulfillment of social needs in the Jakarta area. In its construction, it is necessary to design a good drainage system and fullfill safety standards, especially in dealing with potential flooding in the area. The methodology used in the design of the drainage system is literature study, data collection, problem analysis, design, and ending with drawing. The data collected comes from the Meteorology, Climatology and Geophysics Agency (BMKG); Center for Research & Development of Water Resources (PUSAIR); and the Geospatial Information Agency (BIG). The first analysis carried out was a flood analysis of the area with the target location, namely the Krukut River and the Ciragil River. Floods that occur with a return period of flood discharge in the area of 50 years indicate that the Senayan Park area is not affected by the regional floods. Furthermore, the second analysis is carried out, namely the design of the dimensions of the drainage system in the Senayan Park area. The drainage system design resulted in 4 types of channels being used. The first channel is the U ditch drill type with dimensions of 40x40, 50x50, and 60x60 cm. The second channel is a box culvert with dimensions of 40x40, 50x50, and 60x60 cm. The third channel is a 4-inch pvc vertical pipe. The fourth channel is a semi-circular pvc gutter with dimensions of 6 and 8 inches. The results of the drainage system design are safe for the flood discharge in the area with a return period of 2 years. Finally, analysis of the addition of the lake water level as a reservoir area is carried out. With the flood discharge for the 10-year return period, it is found that the lake water level will increase as high as 0.05 m. All the design results can be categorized as safe in accommodating rainwater runoff according to the applicable regulations.
