Political Structure
For the Political Structure of my society I would have my society ruled by a King and his Government Officials. The King would have a large portion of power. The Government Officials would live near or on palace grounds depending on their power and also have lots of power. Then there were the Nobles who had near equal power with the government officials and occasionally surpass government officials in power and have the officials demoted to a lower rank in the political structure. Then there are Peasants and Slaves that live on the outer ring. Peasants will not be poor but they will not be rich and some may decide to live outside of the City's protective walls and work the farms. Slaves must be treated fairly and must be properly fed or their owner will be fined. Taxes will be important and very rich people will be taxed more heavily so they do not try to bribe generals into using the army into overthrowing the Government.
Social Structure
The king and the government officials will live the best life possible within the city and will be well fortified from angry people and enemy's and will have state of the art technology within their houses. People in the government will have a special advantage to get new technology before it goes into the market making it impossible for anybody outside the government to have up to date houses .The nobles will have only what they can afford and the technology in the houses will be a bit less cunning. Nobles and and other higher ranking people will be able to have a certain amount of slaves depending on their amount of power. Peasants will mostly live their lives outside of the city working on farms or mines and plantations. Slaves will not live with their masters unless the masters allow it. Slaves will do lots of work but they will be payed and they can buy their freedom and start a life. If slaves are not allowed to live in their masters homes there will be places made for slaves to stay in.
Communication
Each ring in the city has its own group of trucks and planes between different areas. If you are to communicate with some one inside your ring then you would have a truck deliver your message or package to them. If you wanted to send a message to someone outside your ring or outside the city you would have a truck deliver that to but it would be more expensive. If someone is to send you a package from out of the city it will be expensive and will be brought to you by the city's post office in a truck or plane depending on the distance. Planes would be the most expensive mailing system.
Religion and Beliefs
My city has no religions because religion can cause conflict and death because different parts of religions contrast from other religions and every one thinks that their religion is the right one. Religion is illegal and the penalty for breaking that rule is banishment no matter your position in political ranking, even if you are king. All beliefs come from science and no body can say otherwise or you will be sent to jail or whipped publicly and disgraced.
Economy
Trade will be a major interaction between my city and other city's because of my city's location. My city will be an hour drive at 70 mph and will have many boats floating around the in the water. Only certain things can be sold at certain times. Trade on land either be by trains or trucks depending on the distance and the due date. There will be economic agents checking what's being shipped and that its not something that's illegal. Economic agents have the power to arrest and to kill if they are threatened by civilians.
Technology
My city will have many underground pipes carrying water into the city from the mountains,lakes,and dams.All of the technology will be Eco friendly and will be installed into every house even if you don't have enough money to buy the technology. The army will be divided into 12 legions of 7,000 men each. Troops will use extremely advanced weaponry and 40% of monthly taxes will be used to support the army. In the streets of the the city gas stations will only be used for charging cars because all cars will either be Solar Panel cars, Hybrids, and Tesla's. If you have to find gas for your Hybrid car, the city will not be responsible for supplying your car with gas.
Aesthetics
The palace will be massive and it will be the most beautiful building in all the city. It will have wide, sturdy columns. It will have artificial ponds that will have fish, frogs, and other creatures. The closer you moved towards the center of the city, the more grand the buildings will be. Government Officials had very large houses and some even owned retirement villas out on the country side where they can still be protected by the army. Roads are very sturdy and sidewalk stone blocks are chiseled with extremely detailed patterns
Geography
My surroundings will be lots of flat land, some hills, giant mountains far off into the distance, rivers, lakes, and the border between the Atlantic and Arctic Ocean on the coast. My city will be placed a safe distance from the volcanoes in the area but still close enough that the land is still very fertile. There will be a good amount of rain and canals water away from dams and reservoirs so that they do not flood and can only be opened by a control panel inside the facility that is in charge of watching the water levels.
