Comprehensive planning is an ordered process that determines community goals and aspirations in terms of community development. The end product is called a comprehensive plan, also known as a general plan, or master plan. This resulting document expresses and regulates public policies on transportation, utilities, land use, recreation, and housing. Comprehensive plans typically encompass large geographical areas, a broad range of topics, and cover a long-term time horizon. The term comprehensive plan is most often used by urban planners in the United States. Each city and county adopts and updates their plan to guide the growth and land development of their community, for both the current period and the long term. This "serious document" is then the foundation for establishing goals, purposes, zoning and activities allowed on each land parcel to provide compatibility and continuity to the entire region as well as each individual neighborhood. It has been one of the most important instruments in city and regional planning since the early twentieth century. During the earliest times of American history, cities had little power given to them by State governments to control land use. After the American Revolution, the focus on property rights turned to self-rule and personal freedom, as this was a time of very strong personal property rights. Local governments had simple powers which included maintaining law and order and providing basic services. Cities had little power, if any at all, to direct development in the city. Cities began to focus on the provision of basic services during the 1840s at a time known as the Sanitary Reform Movement. During this time it became clear that there was a strong relationship between disease and the availability of a quality sewer system. Part of the movement included the development of sanitary survey planning to help bring sewer systems to infected parts of cities. From this planning also developed a new consciousness of townsite location.
