Not in my back yard, or NIMBY () for short, is a common phrase describing the opposition by residents to proposed real estate and infrastructure developments in their local area, as well as support for strict land use regulations. It carries the connotation that such residents are only opposing the development because it is close to them and that they would tolerate or support it if it were built farther away. The residents are often called nimbys, and their viewpoint is called nimbyism. The opposite movement is known as YIMBY ("yes in my back yard"). Some examples of projects that have been opposed by nimbys include housing development (especially for affordable housing or trailer parks), high-speed rail lines, homeless shelters, day cares, schools, universities and colleges, music venues, bike lanes and transportation planning that promotes pedestrian safety infrastructure, solar farms, wind farms, incinerators, sewage treatment systems, fracking, and nuclear waste repositories.
Rationale
Developments likely to attract local objections include:
Infrastructure development, such as new roads and rest areas, railway, light rail and metro lines, airports, power plants, retail developments, sales of public assets, electrical transmission lines, wastewater treatment plants, landfills, sewage outfalls and prisons; Waste facility development, e.g. exploration of disposal sites for nuclear/radiation waste; The extraction of mineral resources including ore, aggregates and hydrocarbons from mines, quarries and oil wells or gas wells, respectively; Renewable energy generators, such as wind farms and solar panels; Businesses trading in goods perceived as immoral, such as adult video, liquor stores, and cannabis dispensaries; Accommodations perceived as primarily benefiting disadvantaged people, such as subsidized housing for the financially disadvantaged, supportive housing for the mentally ill, congregate living care homes (as for the developmentally disabled), halfway houses for drug addicts and criminals, and homeless shelters. Services catering to certain stigmatized groups (for example, injection drug users), such as methadone clinics, syringe exchange programmes, drug detoxification facilities, supervised injection site; Large-scale developments of all kinds, such as big-box stores and housing subdivisions.
The claimed reasons against these developments vary, and some are given below.
Increased traffic: more jobs, more housing or more stores correlates to increased traffic on local streets and greater demand for parking spots. Industrial facilities such as warehouses, factories, or landfills often increase the volume of truck traffic. Harm to locally owned small businesses: the development of a big box store may provide too much competition to a locally owned store; similarly, the construction of a new road may make the older road less traveled, leading to a loss of business for property owners. This can lead to excessive relocation costs, or to loss of respected local businesses. Loss of residential property value: homes near an undesirable development may be less desirable for potential buyers. The lost revenue from property taxes may, or may not, be offset by increased revenue from the project. Environmental pollution of land, air, and water: power plants, factories, chemical facilities, crematoriums, sewage treatment facilities, airports, and similar projects may—or may be claimed to—contaminate the land, air, or water around them. Especially facilities assumed to smell might cause objections. Light pollution: projects that operate at night, or that include security lighting (such as street lights in a parking lot), may be accused of causing light pollution. Noise pollution: in addition to the noise of traffic, a project may inherently be noisy. This is a common objection to wind power, airports, roads, and many industrial facilities, but also stadiums, festivals, and nightclubs which are particularly noisy at night when locals want to sleep. Visual blight and failure to "blend in" with the surrounding architecture: the proposed project might be ugly or particularly large, or cast a shadow over an area due to its height. Loss of a community's small-town feel: proposals that might result in new people moving into the community, such as a plan to build many new houses, are often claimed to change the community's character. Strain of public resources and schools: this reason is given for any increase in the local area's population, as additional school facilities might be needed for the additional children, but particularly to projects that might result in certain kinds of people joining the community, such as a group home for people with disabilities, or immigrants. Disproportionate benefit to non-locals: the project appears to benefit non-local people, such as non-citizen investors or job creation (in the case of commercial projects like factories or big-box stores) or harm people from neighboring areas (in the case of regional government projects, such as airports, highways, sewage treatment, or landfills). Increases in crime: this is usually applied to projects that are perceived as attracting or employing low-skill workers or racial minorities, as well as projects that cater to people who are thought to often commit crimes, such as the mentally ill, the poor, and drug addicts. Additionally, certain types of projects, such as pubs or medical marijuana dispensaries, might be perceived as directly increasing the amount of crime in the area. Risk of an (environmental) disaster, such as with drilling operations, chemical industry, dams, or nuclear power plants. Historic districts: the affected area is on a heritage register, because of its many older properties that are being preserved as such. The cause of NIMBYism is seen by some due to spatially concentrated costs and diffuse benefits together with regulatory transaction costs which result in a failure of conflict resolution. As hinted by the list, protests can occur for opposite reasons. A new road or shopping center can cause increased traffic and work opportunities for some, and decreased traffic for others, harming local businesses. People in an area affected by plans sometimes form an organization which can collect money and organize the objection activities. NIMBYists can hire a lawyer to file formal appeals, and contact media to gain public support for their case.
