If a walkout is open to rainfall, what provision is needed at the bottom of the walkout stairway?

When a walkout is exposed to rainfall, it is important to have a drainage provision at the bottom of the walkout stairway to manage water runoff effectively. Without proper drainage, rainwater can accumulate at the base of the stairs, posing hazards such as flooding and water infiltration into nearby structures. This can lead to issues like mold growth, deterioration of building materials, and safety hazards due to slippery conditions.

The drainage provision usually involves designing the terrain to allow water to flow away from the stairs, utilizing gutters, drains, or gravel beds that facilitate proper water management. By ensuring that water is directed away, this provision helps maintain a dry, safe environment for individuals using the walkway and minimizes the potential for damage to the structure. Proper drainage is a critical aspect of maintaining not only safety but also the longevity of the walkout and the surrounding area.
