In land-use planning, a locally unwanted land use (LULU) is a land use that is useful to society, but objectionable to its neighbors.
LULUs can include power plants, dumps, prisons, roads, factories, hospitals and many other developments. Planning seeks to distribute and reduce the harm of LULUs by zoning, environmental laws, community participation, buffer areas, clustering, dispersing and other such devices. Thus planning tries to protect property and environmental values by finding sites and operating procedures that minimize the LULU’s effects.
LULUs always provide services a community needs, but few people want to live near them because of their externalities, real or perceived.
