An industrial land (also known as industrial estate, trading estate) is an area zoned and planned for the purpose of industrial development. An industrial land can be thought of as a more “heavyweight” version of a business park or office park, which has offices and light industry, rather than heavy industry. Industrial parks are usually located on the edges of, or outside the main residential area of a city, and normally provided with good transportation access, including road and rail. Different industrial land fulfill these criteria to differing degrees. Many small communities have established industrial land with only access to a nearby highway, and with only the basic utilities and roadways. Public transportation options may be limited or non-existent. There may be few or no special environmental safeguards.
