Safeguarding Aerodromes and Air Traffic Technical Sites

9.75 Under the requirements of DfT/ODPM Circular 1/2003, 'Safeguarding Aerodromes, Technical Sites and Military Explosives Storage Areas', the Council is required to put in place a policy protecting these sites from inappropriate development. Calderdale does not posses any Military Explosives Storage Sites, nor does it fall within the protection area for any such site outside the District. As a result this section deals purely with the safeguarding of aerodromes and technical sites.

9.76 The main elements of concern arising from this Circular are the wind turbine consultation zone and the Aerodrome Safeguarding Map (concerned with building heights) for Leeds/Bradford Airport (LBA) and the protection zone for the technical area (concerned with air traffic control) at Hameldon Hill, between Burnley and Accrington in Lancashire. The areas shown on the Proposals Map are neither the responsibility nor the proposal of the Council.

9.77 The Safeguarding Zones for Leeds/Bradford Airport and the Leeds/Bradford Airport Wind Turbine Consultation Zone are shown on the Proposals Map. All planning applications or development proposals for buildings, structures, erections and works falling within the criteria laid down within ODPM Circular 1/2003 are subject to consultations with the airport or site operator as follows:-

  • Within the LBA Safeguarding Zone the criteria for Calderdale indicate that consultations are necessary where the development proposals for buildings, structures, erections and works proposed are over 45 metres high.
  • Within the LBA Wind Turbine Consultation Zone applications for wind turbine proposals within 30 km of the airport are subject to consultation with the Airport Operator. The 30 km radius is a guideline to indicate that statutory consultation is necessary. However, depending upon the terrain, proposals beyond 30 km may sometimes prove to be problematic to aircraft safety and the operations of the airport. The Council will liaise with the Airport Operator in respect of wind turbine proposals in excess of 30 km to assess whether the Airport Operator wishes to be formally consulted on these proposals as well to ensure that air safety is taken into account in the determination of proposals. The Airport Operator will take the cumulative effects of wind turbine developments into account.

9.78 The development of tall buildings, erections, structures or works can be a physical obstacle to aeroplanes and in addition to the physical obstacle that wind turbines can produce, the rotating blades can create certain problems particularly from the electro-magnetic fields, which may cause interference with navigation and aeronautical systems. The amount of interference depends on the number of turbines, their size, construction materials and location and on the shape of their blades.

9.79 With respect to the Hameldon Hill Technical Site, consultations will be required for different heights of development depending upon their location within the safeguarded zone. This is because of the refracting effects of buildings upon radar signals and therefore the interference that can be caused affecting air safety. It is not intended to show the detailed zoning on the Proposals Map. However, generally within the Calder Valley and the towns lying within it height consultations will only be necessary for development in excess of 45.7 metres high. On parts of the high moorland, over 390 metres elevation, all planning applications will be referred for consultation. There is a sliding scale for consultations for varying heights of buildings. The detailed maps are kept within Planning Services and may be consulted during normal office hours.

Policy T 27

Safeguarding Aerodromes and Air Traffic Technical Sites

Officially safeguarded areas have been established for Leeds/ Bradford Airport and the Hameldon Hill Technical Site. Certain applications for development will be the subject of consultation with the operator of the aerodrome or technical site and restrictions in height, or detailed design of buildings or development (likely to create a bird strike hazard) may be necessary as set out in DfT/ODPM Circular 1/2003.
