What is the maximum gradient of a sidewalk according to BP 344?

The maximum gradient of a sidewalk as stipulated in BP 344 is indeed 1:20. This regulation is significant as it aims to ensure accessibility for individuals with disabilities. A gradient of 1:20 means that for every 20 units of horizontal distance, there can be a maximum rise of 1 unit. This slope is considered to facilitate easier navigation for wheelchair users and those with mobility impairments, making public spaces safer and more accessible.

The choice of a 1:10 gradient would be too steep, posing challenges for those with mobility issues, while a gradient of 1:50 or 1:100 would be too shallow and may not be practical in most sidewalk contexts. Thus, the specification of 1:20 strikes a balance between functionality and safety, aligning with the goals of promoting universal design in public access areas.
