Some planners are involved in environmental issues ranging from pollution control to wetland preservation, forest conservation, or the location of new landfills. Planners also may be involved with drafting legislation on environmental, social, and economic issues, such as sheltering the homeless, planning a new park, or meeting the demand for new correctional facilities. Planners examine proposed community facilities such as schools to be sure these facilities will meet the changing demands placed upon them over time. They keep abreast of economic and legal issues involved in zoning codes, building codes, and environmental regulations. They ensure that builders and developers follow these codes and regulations.
Planners also deal with land use issues created by population movements.
For example, as suburban growth and economic development create more new jobs outside cities, the need for public transportation that enables workers to get to these jobs increases. In response, planners develop transportation models for possible implementation and explain their details to planning boards and the general public. Before preparing plans for community development, planners report on the current use of land for residential, business, and community purposes. These reports include information on the location and capacity of streets, highways, water and sewer lines, schools, libraries, and cultural and recreational sites. They also provide data on the types of industries in the community, characteristics of the population, and employment and economic trends.
