The city accommodates 100,000 of citizen and the city hierarchy is based on a democratic political system. The city is located at the East Coast of Malaysia and the close proximity with the sea thus increases the likeliness of flood. According to urban structure, the city was planned to give visual openness by locating medium and high level of tower type skyscrapers properly. It uses maglev transportation such as maglev train, maglev urban pod and maglev bicycle that reduces noise and pollution. For the water and waste management, household sewage is channelled to the sewage treatment plant through underground pipe while the organic waste products are channelled to an incinerator. The energy management system is based on local production and consumption of renewable energy such as solar energy and wave energy. Blue Sapphire has a resilient plan for each zone of the city and it is shown in the table below.
