Infrastructure refers to the physical support services necessary for development. At the simplest level, a road, driveway, or easement of some type is essential to gaining property access and allowing development on a property. Other infrastructure can include water or sewer lines in developed areas, or wells and irrigation channels in rural areas. Electrical power, telephone lines, television cable and fiber optic are also considered infrastructure. Generally, the more people expected at a site, the more infrastructure that is needed to provide services.
