When considering how drainage from exterior doorways should be structured, it is essential to understand the principles of directing water away from the entrance to prevent water intrusion into the home. A step-up for water diversion effectively directs rainwater or surface water away from the doorway, minimizing the risk of flooding or moisture damage at the entry point. This method creates a physical barrier that channels water away from the door, ensuring that water does not pool at the threshold or enter the space.

Constructing a slope toward the doorway would have the opposite effect, drawing water toward the entrance and increasing the risk of water damage. Having the doorway at the same level as the flooring also allows for potential flooding and water entry, as there is no mechanism in place to divert water away. While having an under-surface drainage system can be beneficial in some contexts, the step-up mechanism provides immediate physical protection and is often a straightforward solution to ensure efficient drainage in high rainfall scenarios.
