my sustainable city
My city is sustainable because in the left bottom corner i have my industrial park. This park contains the sewage and water supply and the industries. It is away from the houses and businesses. The source of transportation is trams because they are self efficient and safe. The houses are on the right side and the businesses are on the left so they don't have to use as much gas to go around the whole city. The houses are by the ocean so they get that ocean breeze and don't have to use as much air conditioning in the summer.
