While Jakarta has serious evacuation plans, there are apparently also plans to build a new and unique sea wall. Quote from an article from 2016:
“The National Capital Integrated Coastal Development consortium will build a new set of barrier islands and a sea wall that will guard the city from waves and storm surges. The extensive project will take the shape of the Garuda, a mythical bird and symbol of Indonesia. While construction is already under way (the first pile was planted in October 2014), KuiperCompagnons, the Dutch firm behind much of the design, estimates that the project will take 30 to 40 years to complete.”
And this is Garuda:
Quote from wikipedia:
“Garuda is described as the king of the birds and a kite-like figure. He is shown either in a zoomorphic form (a giant bird with partially open wings) or an anthropomorphic form (a man with wings and some ornithic features). Garuda is generally portrayed as a protector with the power to swiftly travel anywhere, ever vigilant and an enemy of every serpent. Garuda is a part of state insignia of India, Indonesia and Thailand. The Indonesian official coat of arms is centered on the Garuda and the national emblem of Indonesia is called Garuda Pancasila.”
