High externality areas

In land use planning, a locally unwanted land use (LULU) is a land use that creates externality costs on those living in close proximity. These costs include potential health hazards, poor aesthetics, or reduction in home values. LULUs often gravitate to disadvantaged areas such as slums, industrial neighborhoods and poor, minority, unincorporated or politically under represented places that cannot fight them off. LULUs can include power plants, dumps (landfills), 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.

An externality is something that happens as a result of a transaction that affects an uninvolved third party. LULU's present externalities in various ways, most notably those that inflict the senses: harsh smell, reduced aesthetics, noise pollution, and poor livability.

It has been suggested that a correlation exists between the location of sites considered as locally unwanted land uses and the proximity to minority populations as a result of market dynamics. That is, externalities associated with LULUs (such as poor aesthetics, lack of desirable amenities, etc.) tend to discourage high earning buyers from moving to the area, and thus perpetuate the cycle in which low income individuals have few choices except those which happen to be in areas with LULUs such as landfills and highways. This tends to lower home values. Further, the same market forces, especially those that may discriminate against minorities, could make it so that these areas happen to be populated predominantly by minorities. Throughout the United States, "three out of five African Americans and Latino Americans live in communities with abandoned toxic waste sites." This pattern is typically seen because of discrimination and racism throughout the infrastructure development process. It is becoming more and more common. What makes a LULU such as this unique is that they cause displacement, whereas a landfill, dump, roads, or prisons simply discourage home buyers from entering the area and keep home prices low. High end health food stores such as Whole Foods causes displacement by attracting high earning home buyers into the area, causing rents and home prices to rise. This has been dubbed the "Whole Foods effect".

Boston has been known historically for the high cost of living that accompanies residence there, as well as being subject to various urban renewal projects during America's Urban Renewal era. These renewal projects often caused the displacement of Jewish and Italian immigrants as well as working class individuals in surrounding areas in its earliest years.

Superfund, or the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, was created to mitigate the cleanup and costs thereafter of hazardous waste sites. Superfund sites are often thought of when discussing LULUs. Love Canal was the first superfund site, established because of chemical waste that was being dumped into the canal by Hooker Electrical Company, later known as Hooker Chemical Company. The incident attracted widespread media attention and the neighborhoods surrounding Love Canal have since been destroyed. It has been suggested that some of these sites tend to be located in areas that have a high number of low income, minority residents.

Of the 1,000+ Superfund sites in America, 25% of them (both capped and active) are situated directly on or near Native American reservations. Many of these sites can interfere with various rituals and affect cultural objects, and create further conflict between the Government and affected tribes. As discussed in a report from the All Indian Pueblo's Office of Environmental Protection, "the Superfund HRS [Hazard Ranking System] model does not account for Indian religious and ceremonial impacts from sites. Due to their importance in Pueblo life, culturally significant plants, animals, ceremonial surface water use, and sacred areas should be considered as critical impacts when evaluating the various pathways of exposure of the HRS.”
