Research the origins of your city by visiting your county courthouse and local library. Check out early photographs and maps of your area to give you an idea of what went into the planning of your community. Visit local historic areas to learn about the development and history behind old buildings. You may also consider getting involved in efforts to preserve local buildings and areas that are threatened.

With the help of a teacher or academic adviser, arrange to interview a planner to learn about his or her job. Another good way to see what planners do is to attend a meeting of a local planning commission, which by law is open to the public. Interested students can find out details about upcoming meetings through their local paper or planning office.

Urban and regional planners assist in the development or maintenance of carefully designed communities. Working for a government agency or as a consultant, planners are involved in integrating new buildings, houses, sites, and subdivisions into an overall city plan. Their plans must coordinate streets, traffic, public facilities, water and sewage, transportation, safety, and ecological factors such as wildlife habitats, wetlands, and floodplains. Planners are also involved in renovating and preserving historic buildings. They work with a variety of professionals, including architects, artists, computer programmers, engineers, economists, landscape architects, land developers, lawyers, writers, and environmental and other special interest groups.

Urban and regional planners also work with unused or undeveloped land. They may help design the layout for a proposed building, keeping in mind traffic circulation, parking, and the use of open space. Planners are also responsible for suggesting ways to implement these programs or proposals, considering their costs and how to raise funds for them.

Schools, churches, recreational areas, and residential tracts are studied to determine how they will fit into designs for optimal usefulness and beauty. As with other factors, specifications for the nature and kinds of buildings must be considered. Zoning codes, which regulate the specific use of land and buildings, must be adhered to during construction. Planners need to be knowledgeable of these regulations and other legal matters and communicate them to builders and developers.

Some urban and regional planners teach in colleges and schools of planning, and many do consulting work. Planners today are concerned not only with city codes, but also with environmental problems of water pollution, solid waste disposal, water treatment plants, and public housing.

Planners work in older cities or design new ones. Columbia, Maryland, and Reston, Virginia, both built in the 1960s, are examples of planned communities. Before plans for such communities can be developed, planners must prepare detailed maps and charts showing the proposed use of land for housing, business, and community needs. These studies provide information on the types of industries in the area, the locations of housing developments and businesses, and the plans for providing basic needs such as water, sewage treatment, and transportation. After maps and charts have been analyzed, planners design the layout to present to land developers, city officials, housing experts, architects, and construction firms.

The following short descriptions list the wide variety of planners within the field.

Human services planners develop health and social service programs to upgrade living standards for those lacking opportunities or resources. These planners frequently work for private health care organizations and government agencies.

Historic preservation planners use their knowledge of the law and economics to help preserve historic buildings, sites, and neighborhoods. They are frequently employed by state agencies, local governments, and the National Park Service.

Transportation planners, working mainly for government agencies, oversee the transportation infrastructure of a community, keeping in mind local priorities such as economic development and environmental concerns.

Housing and community development planners analyze housing needs to identify potential opportunities and problems that may affect a neighborhood and its surrounding communities. Such planners are usually employed by private real estate and financial firms, local governments, and community development organizations.

Economic development planners, usually employed by local governments or chambers of commerce, focus on attracting and retaining industry to a specific community. They communicate with industry leaders who select sites for new plants, warehouses, and other major projects.

Environmental planners advocate the integration of environmental issues into building construction, land use, and other community objectives. They work at all levels of government and for some nonprofit organizations.

Urban design planners work to design and locate public facilities, such as churches, libraries, and parks, to best serve the larger community. Employers include large-scale developers, private consulting firms, and local governments.

International development planners specialize in strategies for transportation, rural development, modernization, and urbanization. They are frequently employed by international agencies, such as the United Nations, and by national governments in less developed countries.
