  • Historical map review
  • Environmental data reports
  • Geological appraisal
  • Hydrology and Hydrogeology
  • Local Authority records e.g. planning, environmental health and building control.
  • County Council records e.g. Petroleum Officer, Archaeology.
  • Obtaining information and data from: Environmental Agency, Natural England and Statutory Utility Companies (i.e. water and electricity)
  • Historical aerial photographs
  • Preparation of conceptual model and site investigation strategy
  • Assessment of constraints to development
