DA5 Changes of level in public spaces
Where level changes cannot be levelled off or sloped away across larger sites, the public space affected should be made accessible by handrailed steps and short ramps starting and finishing at the same point, or by signposted alternative route options. Signposted alternative route options should include steps and lifts where long ramps and steeper slopes would be too tiring or steps too high even with rest landings for all people to use without discomfort.
The BS 8300:2009 Code Of Practice recommends the provision of lifts in urban contexts where changes of level exceed 2m.
Gradients in excess of 1:12 will be resisted unless alternative and acceptable step-free routes are provided.
