The Republic of Indonesia is expected to become the fifth largest economy in the world by 2030, and this vision will also become an important turning point for the Republic of Indonesia. The fast-growing middle class has created tremendous opportunities for the country's development, and climate change and population and economic growth may also hinder its future development. This series of hazards includes surface subsidence, rising sea levels, and the resulting flooding in Jakarta. The giant seawall will be the most favorable measure to protect the city. Land reclamation is an important part of the seawall construction project, and this series of initiatives will likely bring valuable future development opportunities to the Jakarta region. Related departments believe that a large-scale land reclamation plan seems to be the only way to achieve a green city in Jakarta and meet the needs of society. Design highlights: abandon the wisdom development of the traditional land reclamation model; multi-story urban master plan based on diversity. Indonesia has the second longest coastline in the world, but most cities do not have a good interaction with the sea. In order to make the new living life truly compatible with the marine environment, the overall plan of the project is based on the good relationship between people and the environment, creating a new park, plaza and public pedestrian transportation network to promote the communication between the citizens of Jakarta and the sea. Depicts the coastal nature of Indonesia. Inspired by the Manhattan City Network (60 m x 160-240 m), the city's network illustrates a sustainable urban development model that operates in a compact, diverse urban environment. Other examples of urban planning such as Barcelona, ​​Savannah, Ipanema, Shanghai, Shenzhen, Amsterdam, Venice, Copenhagen, Vienna and Los Angeles also showcased the world's development models at different scales. The master plan for the project concept includes parks, leisure, energy, things, water, land, water transportation, medical and education, culture and religion, housing and security. The elliptical island conceived by the project is called “Green Manhattan” and is expected to welcome 1.9 million urban residents. Unlike the Dubai model, an integrated urban structure that meets the needs of social diversity will be built here. A new urban planning strategy will promote urban employment and create a near-ideal living environment for the middle class and even low-income groups and fishermen. And it is expected to become the most green and ecological city in the world. The public will enjoy the rich tropical rainforest gardens, canals, lakes and beaches. The new urban plan is expected to achieve the following goals: 50% green plants and open ocean space, net carbon dioxide emissions are zero, crops self-production reaches 50%, water self-sufficiency reaches 80% of total water consumption, and green energy supply reaches 150%. The garbage collection rate reaches 150%, 90% of the car-free space is equipped with public and private automated transportation, satisfying every 10 residents to enjoy an environmentally-friendly solar public transportation, 20% of residents using water transportation commuting, and urban residents enjoying 200 meters of the largest public transportation. Distance, the ratio of people to bicycles is 1:1. In business development, 20% is used for the development of low- and middle-income people and trade markets. Summary: The master plan is a collection of dual urban frameworks for urban ecological construction and urban social construction.
