Work in an area of archaeological importance (AAI)

You must complete and return an operations notice (free of charge) to our Design, Conservation and Sustainable Development team and the York Archaeological Trust (YAT) before any work can start in an AAI, including:

  • disturbance of ground
  • tipping on the ground
  • flooding of the ground

The York Archaeological Trust (YAT) will decide whether:

  • they have any interest in your intended work
  • archaeological intervention is required

The scale of any potential archaeological work will depend on the level and nature of the intended works.

Areas of archaeological importance (AAI) and the law

It's an offence to carry out work in an AAI without an operations notice or within six weeks of submitting the notice.

It's also an offence to use a metal detector within an AAI.
