Abstract: Jakarta faces significant challenges due to flooding caused by geographic and anthropogenic factors. Situated on a delta formed by over 13 rivers converging at Jakarta Bay, the city is highly vulnerable to recurrent floods, exacerbated by severe land subsidence in northern areas. Major flood types include tidal flooding, fluvial flooding from high river discharge during heavy rainfall, and pluvial flooding from trapped rainwater. Historical data shows an increase in extreme rainfall intensity, with annual maximum daily rainfall rising by 10-20 mm per decade since 1960. The NCICD (National Capital Integrated Coastal Development) flood mitigation strategy is divided into three stages (A, B, and C). Stage A focuses on strengthening coastal and river mouth embankments for immediate protection, while Stages B and C involve constructing outer sea dikes for medium- and long-term flood control. To date, over 13 kilometers of embankments have been built, reducing flood-affected areas by 1,300 hectares and protecting over 10,000 residents. The success of Stage A highlights the importance of integrated solutions to mitigate flooding and enhance community resilience. Future plans aim to integrate sanitation improvements, upstream-downstream flood control measures, and coastal revitalization to ensure sustainable development and unlock Jakarta’s economic potential as a coastal metropolis.
