Urban Planning Vocabulary Quiz

Zoning is the legal process by which local authorities divide land into areas (zones) and regulate how each area can be used. Common zones include residential (housing), commercial (shops and offices) and industrial (factories and warehouses). Zoning controls the type, height and density of buildings and helps manage city growth.

Gentrification is the process by which a poorer neighbourhood is transformed through the influx of more affluent residents and businesses. As property values and rents rise, long-standing residents and businesses are often displaced. It can improve infrastructure but is controversial because it can cause the loss of community identity and affordable housing.

A brownfield site is a previously developed piece of land that is no longer in use, often because its former industrial or commercial activity has left contamination. Brownfield development is generally preferred over greenfield development because it reuses existing urban land and can help regenerate deprived areas.

The green belt is a policy of protected open land around urban areas, designed to prevent urban sprawl, protect the countryside and encourage regeneration within existing urban areas. In England, green belt land is strictly protected from development. Supporters say it preserves landscapes; critics argue it restricts housing supply and drives up prices.

Mixed-use development combines different types of land use — such as residential, commercial and recreational — within a single building or neighbourhood. For example, a building might have shops on the ground floor, offices in the middle and flats above. It encourages walkable communities and reduces the need for car travel.

Densification refers to increasing the number of people or homes in a given urban area by building more compactly, for example through taller buildings or converting large houses into flats. It is seen as a way to accommodate population growth without expanding into greenfield land.

Planning permission is the formal consent from a local authority required before certain types of building work or change of use can take place. Major developments — such as new houses or commercial buildings — must submit a planning application and receive approval before work begins.

Urban sprawl refers to the uncontrolled, low-density expansion of urban areas into the surrounding countryside, often characterised by car-dependent suburban housing estates and retail parks. Sprawl is associated with increased car use, loss of farmland and biodiversity, and longer commutes. Planning policies such as green belts aim to limit sprawl.

A masterplan is a comprehensive, long-term planning document that sets out a vision for how a large area will be developed. It typically covers land use, transport connections, open space and housing density. Masterplans are used for large new housing estates and urban regeneration projects.

Infrastructure refers to the fundamental facilities that support a city: roads, railways, water supply, sewerage, electricity, communications, schools and hospitals. New development must be supported by adequate infrastructure, or the local authority may require developers to contribute through Section 106 agreements or the Community Infrastructure Levy (CIL).
