8 National Capital Integrated Coastal Development Project | Master Plan | Draft 1 April 2014• an offshore solution offers many opportunities for the development of the coastal zone and to contribute to the socio-economic development of theNational Capital of Indonesia as laid down in the MP3EI plan.The main goal of the NCICD Master Plan is therefore to offer Jakarta long termprotection against flooding from the sea and rivers in the coastal area, and at thesame time facilitate socio-economic development.Realising this goal requires an integrated planning approach. This Master Plan istherefore a Master Plan for both flood protection and for coastal development.1.3.From JCDS to Master PlanThis draft Master Plan of the National Capital Integrated Coastal Development(NCICD) project contains the results of the planning process in the period January2013 - March 2014.The NCICD project follows the Jakarta Coastal Defence Strategy project thatresulted in a strategy for flood protection. In the Strategy Consolidation phase ofthe NCICD project, assumptions underpinning the Strategic Direction and designaspects of the Strategic Direction were researched. Conclusions from this addi-tional research led to an optimised version of the JCDS: the Final ImplementationModel (FIM).This draft Master Plan was developed on the foundation of the FIM. Furtherresearch into spatial aspects, engineering of solutions, financial and economicaspects and environmental impacts was done to further substantiate the choicesmade in this Master Plan.The Master Plan is not the final planning stage. After approval, detailed designsand feasibility studies for components will have to be prepared, either by theIndonesian government or by private investors. Also funding and contractingprocedures will require additional planning or revision of existing plans. This willbe further elaborated in the final draft Master Plan.FURTHER READING:• JCDS reports (2011): Atlas, Agenda, Aturan MainJCDS InceptionphaseStrategyConsolidation phaseOptionsphaseDesignphaseAtlasAgendaAturan-MainInception reportFinal Implementation ModelDraft Master PlanMaster PlanDraft 1 April 2014 | Master Plan | National Capital Integrated Coastal Development Project 15
1.1. 2007: A different floodThe 10 million inhabitants of the Jakarta metropolitan area (Indonesia) are usedto flooding in the rainy season. Sedimentation and waste accumulation, com-bined with peak river discharges, create occasional floods in the 13 rivers andcanals flowing through the low lying urban delta. Street flooding caused by heavyrainfall is a more common event, as the city struggles to keep the urban drainagesystem in pace with urbanization. However, in November 2007 North Jakarta washit by a different flood. A high tide over-topped the sea wall on several locationsand sea water was rushing through the streets creating high waters up to 1,5metres deep for several days.This flooding from the sea confirmed what some researchers already had beenwarning for: North Jakarta is subsiding at a staggering speed of 7,5 centimetresper year on average. In some parts subsidence rates even go up to 17 centime-tres per year. Large parts of the city, including the coastal defences, are subsidingfurther and further below sea level.In 2008 the existing sea wall was reinforced, but due to the subsidence this seawall is already at a critically low level. Overtopping at high tide is expected withinthe coming years.1.2. Main goal For several years Indonesia and the Netherlands have been working together to reduce and prevent floods in the National Capital of Indonesia. This collaboration resulted in the Jakarta Coastal Defence Strategy (JCDS) in 2011. Bilateral coopera- tion is continued in the National Capital Integrated Coastal Development (NCICD) project. The JCDS project and the first phases of the NCICD project concluded that: • strengthening the existing seawalls and upgrading the drainage pumping capacity can no longer provide sufficient protection for the long term. Moreo- ver, space in Jakarta is too limited to create the required large storage basins. An offshore solution for flood protection has become inevitable to protect the city against floods from the sea and rivers in the coastal zone.
