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

The correct answer is based on the provisions outlined in BP 344, which pertains to the accessibility of public buildings and spaces. According to this law, the maximum cross gradient of a sidewalk is specified to be 1:100. This means that for every 100 units of horizontal distance, there can be a maximum vertical rise or fall of 1 unit.

Establishing a maximum cross gradient of 1:100 is essential for ensuring that sidewalks are accessible, particularly for individuals using wheelchairs or those with mobility issues. A gentler gradient promotes safer navigation and reduces the risk of accidents, contributing to the overall principle of universal design, which aims to accommodate a diverse range of users.

Looking at the other choices, options like 1:50, 1:20, and 1:10 represent steeper gradients, which could hinder accessibility and safety, making them non-compliant with the regulations stated in BP 344. Choosing a lesser gradient, as specified by the law, ensures that pedestrian pathways are both functional and inclusive.
