The operational team comprises a variety of staff including pilots, paramedics and engineering staff who oversee emergency operations and maintenance of the helicopter. The charity team undertake not only fundraising and public relations associated with the operations of the helicopter, but also the fnancial, strategic, and administrative elements of the Wiltshire Air Ambulance Charity organisation itself. Currently, the charity team are located in leased accommodation in Calne. With the continued growth of the organisation, the charity is quickly running out of space for both their staff and their associated merchandise and public relations materials. At the same time, the operational team is based in a facility located within the Wiltshire Police HQ campus in Devizes. In addition to the physical limitations of the premises, which include compromises in security and access for both the Police and the WAA, the lease of the building from the Police is due to expire in December 2017 and is not renewable beyond this point. As a result the Wiltshire Air Ambulance charity has no option but to investigate the feasibility of relocating to an alternative site. A purpose built facility will future-proof this essential emergency service and give it full control of their life saving operations going forward. 5 2.0 Assessment 2.1 Physical Site Requirements Q1. Location within 7 nautical mile (from Devizes) NO The adjacent fow chart represents the key questions Ideal Development Zone? There have been a number of different factors that asked for each of the potential sites. They are based have determined this location for the new Wiltshire Air on establishing how each site would accommodate the YES Ambulance headquarters, and the site selection has following design challenges: undergone a sequential test in terms of suitability:- Q2. Does the site have NO - Helipad and fight approach corridor good vehicular access? Size of the County - The overall footprint of the new facility Wiltshire is a large rural county covering 1,325 square - Car parking YES miles, which means a relatively central location will - Landscaping and fat topography enable all corners of the county to be adequately served. - Security of airside space Q3. Is the site fat? (topography) NO - Openness of remaining space Neighbouring County Air Ambulances - Not in military controlled space (ground or air) Devon Air Ambulance Trust - Clear of nearby fight hazards (chimneys, pylons etc.) YES Dorset & Somerset Air Ambulance - Away from residential areas Great Western Air Ambulance Q4. Are there buildings or - Good road access for rapid response vehicles Hampshire & Isle of Wight features (overhead cables etc.) that would be unacceptably close YES Thames Valley & Chiltern Air Ambulance to the site with regards to noise The below responses represent the assessment of the or air traffc operability? Outmarsh Farm site. Site Selection NO A1. The site is 5 nautical miles from Devizes At the inception of the project a number of sites were considered, including 18 existing airfelds based in Q5. Is the plot size suffcient A2. Nearest major road is the A350, direct access will be NO Wiltshire. for all required activities? onto High Street Each of these sites were assessed against identical criteria YES A3. The site is essentially fat, currently agricultural in order to establish their appropriateness and ultimate Q6. Is the site in a food risk feasibility for development. YES A4. There are nearby buildings, but these are area? primarily commercial/industrial One of the key criteria for the site was that it was located NO within a 7 nautical mile radius of the current operational A5. Yes, the site is approximately 5ha base to reduce the impact of potential new commuting routes for existing staff. This area was labelled the ‘Ideal Q7. Is the site available for A6. The site is in a Flood Zone 1, low risk NO Location Zone’. acquisition? A7. Yes, the land is privately owned and owner is willing to YES sell the site in full Q8. Are there signifcant A8.
