The history of industrial zones in the USA dates back to the early 20th century, when companies began to cluster in specific areas for reasons of convenience and efficiency. Over time, industrial zones have faced challenges in terms of occupational health and safety, as well as environmental protection. Government agencies have introduced standards and regulations to improve industrial zone management and promote sustainable business practices.The management of industrial zones (or industrial parks) in the United States is often handled by local authorities, such as cities and counties, which put in place regulations to guide the allocation of lots and the choice of projects in these zones.
