Access for Emergency Services
Emergency service access (fire and ambulance) is an important design consideration, particularly for backland or restricted-access sites, and designers should address emergency service needs early in the design process and may need to submit supporting information.
The suitability of access arrangements for the fire service and ambulance service can be an important consideration in the layout and design of development, particularly in relation to backland development or sites with restricted access. Designers should therefore consider the needs of the emergency services early in the design process and may be required to submit information to accompany their proposals indicating how the matter has been addressed.
