I’d recommend dumping a bucket of water down it to see what happens with the drainage. If it puddles next to the foundation, then (based on the picture) I’d recommend an elbow to shoot it away. If it drains away, then I wouldn’t recommend anything.
Is that the reason the underground drain is plugged or is it just stopped up? Ideally, cleanout that underground drain, but lacking that and given slope away I would recommend nothing. They could breakup the sidewalk and run it under, I guess their not open to sledge hammers and concrete mixers (oh well).
They could cut a trough with a concrete saw, not that hard. I think they want to direct water to the left side of the walkway there, so it would need to be a shallow open drain with a grate.
The other way would be ugly, pipe the water along the wall to the back of the house.
Bob…in the picture it looks like the one next door is still going underground…this may just be someone didn’t want to pay to clean the drain out…I’d try that first if it was mine,…jim
Going by age of building, my guess is the underground drain is clay (ceramic) and is cracked, broke. Was there any evidence from inside basement wall of previous water damage or repair?
Bob, I looked at your picture again and notice there is another downspout in the back of the same building and also one mid stream of the walkway on the adjacent building.
Is it possible that is why they used 2’x2’ walkway concrete pads with those big gaps to dissipate the water from the gutters?
They might have back filled with all stone and it is not a problem at all.
I’m speculating here, but hasn’t this been like that for how long and worked?
Not sure what you mean by pads , but that is a standard gangway sidewalk.
Notice the PVC drain is capped and there are four which corrospond with the four drains around this 3 unit building(1952)
Normally those drains would be clay tile, which means they are new , but capped.
The one in back is the only one not capped , but it is also right at the door and looks like they broke the collar to open it and place the downspout inside.
The simplest solution (although not necesarily the right one) is to run the downspout down to the sidewalk with an “A” elbow to direct the water into the gangway.
Bob, it does not look like a monolithic concrete slab, it appears like precast pads, texture is different from one side to the nest and the alignment is irregular indicating not all formed at once and inline.
The wide gap inbetween the pavers would also indicate that it was meant for water to drain in the ground.
The building might be 1953, but I would bet that concrete work isn’t.
Pretty much what I am trying to say indirectly Rick, those big gaps should take care of the water from those gutters, but on the other hand we don’t know the area of roof area that is draining through those downspouts.
I think pointing out a potential freezing of the walkway areas during the Winter caused by the gutter downspouts would do for the Inspections.
