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. Another Type of LULU, is a NIMBY, "Not In My Backyard" which is something very needed in a society, but people do not want within a neighborhood or near them at all, such as an airport, electronics dump, or a military base. LULU's have caused issues in society forever, from the coal powered factories of England, to the Landfills of Kentucky, things needed by everyone but unwanted in a residential area.
LULUs always provide services a community needs, but few people want to live near them because of their externalities, real or perceived.
