What is the maximum acceptable grade for a temporary walkway under normal regulations?

Answer: B — 5%

The maximum acceptable grade for a temporary walkway under normal regulations is 5%. This is established to ensure safety and accessibility for all users, including those with mobility challenges. Walkways with a grade steeper than 5% can become difficult to navigate, especially for individuals using wheelchairs, walkers, or other mobility aids, and could pose a risk of slipping or falling. The standard is designed to provide a level of comfort and safety, allowing pedestrians to transit without excessive effort or risk. For instance, a 2% grade may be more appropriate for areas requiring minimal gradient issues, while 10% or 15% grades exceed safety guidelines and are not typically suitable for public walkways. A grade exceeding 5% becomes increasingly challenging to manage and is usually reserved for specific situations with additional safety features.
