Work in an Area of Archaeological Importance

You must complete and return an operations notice (free of charge) to the City Archaeologist ;and the York Archaeological Trust (YAT) before any work can start in an AAI, including:

  • disturbance of ground (including work by Utilities)
  • tipping on the ground
  • flooding of the ground

York Archaeological Trust 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.

See our guidance document for further information on working in York outside of the planning system.
