LULU stands for Locally Undesirable Land Use, describing facilities that communities recognize as necessary but prefer to have located elsewhere. Examples include landfills, wastewater treatment plants, prisons, homeless shelters, and industrial facilities. LULU decisions often generate NIMBY (Not In My Back Yard) opposition from nearby residents concerned about property values, traffic, noise, or perceived safety risks. Municipal planners must balance the need for these facilities against legitimate community concerns. Fair site selection processes consider equitable distribution so no single neighbourhood bears disproportionate burden, while buffer zones and design standards minimize impacts on surrounding areas.
