In the picture below you can see the original stair dimensions which are still visible in the concrete skimcoat. You can also see the 2nd stairway dimensions outlined in the white paint. This is the wall that had moisture penetration.
Below is the stairway with the dirt and debris cleaned out far enough to allow me to 1. access the wall and waterproof it, and 2. install steeper risers so the stairs don't have such a long horizontal travel. Discovering the hole in the floor, I decided to patch that, too.
Below: I cut new risers after calculating the rise/run which would allow me to walk the stairs without ducking my head. This entailed measuring the total vertical and horizontal distances to be covered and trying to find a rise/run ratio that would get you low enough fast enough to avoid hitting your head but still be walkable.
