Development corporations

In the UK, a development corporation is an independent public body created by the government. They are normally used for long-term projects to regenerate or repurpose land in an area, or to build or extend a new town.

There are three types of development corporation in the UK. Mayoral development corporations (MDCs) must be established when a strategic authority mayor makes a valid request to the government. New Towns Act development corporations (NTDCs) and Urban Development Corporations (UDCs) can also be established by the government. The latter two types of corporation can be centrally-led or locally-led.
