Civic buildings can be constructed that need constant funding to work properly, such as schools, hospitals, parks, police stations, jails, and fire stations. These buildings come in two or more sizes compared to the single, universal types that were used in previous games. Settlements also need public utilities such as electricity with more or less polluting and more or less expensive types of power stations, water pumps, water purification plants, and waste management services. Facilities that had previously provided citywide coverage, such as educational facilities and medical facilities, have been modified to provide more limited coverage, as it has been with police stations and fire stations in previous "SimCity" titles.
