In the early pictures of the garage after the collapse, the first responders there are standing and working in at least ankle deep water. Just saying, it seems that the water intrusion from underground had been going on for quite some time and it is still happening.
I wish someone would set up a camera to see if the water seeps away and comes back to see exactly where the water is coming in.

Let me put it this way. In your previous post you stated this "last picture in the video is what is the most disturbing to me. The last picture was taken a week ago and shows what is left of the garage floor to be completely under water once again. That alone tells me that the property is doomed to flood time and time again and nothing should ever be built on that piece of property."
This building had on going maintenance issues that are well documented and clealry structural issues as a result of on going issues some of which could go back to original construction.
But, this property isn't subject any more or any less to the water table and water intrusion from below ground then the two buildings on either side of it the other Champlain buildings or any other building on that island.
On my island even single family homes have pilings driven through the sand forty feet down to the bedrock. Then the foting cage is constructed and attached then concrete is poured to create the footer, then the foundation erected on that, then the structure on that. They are not just sitting on the sand. I am going to assume this building was built at least to that standard of construction. Did this particular building have insufficeint pilings (it wouldn't be the first time) or pilings driven in the wrong location so portions were not properly supported?(also wouldn't be the first time) this may have caused settling in places that cracked the slab causing the ground water to infiltrate the parking garage and that may be why there was standing water in the garage that came and went even without rain or why it didn't drain during a storm. I am going to assume the slab and garage walls were a monolithic pour. If so this essentially ceates a swiming pool. No water can get in and no water can get out. It makes sense it can't get out. But coming in (unless through the drive) means it is damaged.
I am not going to go back through the thread but I seem to recall they did identify some under size supports in the garage at or near the point of initial collapse and there was some settling and maybe a fractured or damaged support and this was also a location which water was seen pooling. Remeber water seeks it's own level and will run to the lowest spot. Water was also pooling on the pool deck above this location. These would indicate a low spot. Was this support improperly supported below grade? had the support settled or been damaged? Did this crack the garage slab allowing ground water in? Was water from above running through the building and down this area? in your video the guy references the "11's". All the rooms with 11- 111, 211, 611 in the video all had water issues. That would also indicate water was running to this location. The 11's line up with the intial collpase location.
The roof- this guy seems to want to make a case there weren't roof drains? I would find that hard to believe. But a forty year old building would have had a lot of debris over that time running into the drains. Were they clogged? What roof was on this building? Stones? At forty years old not unreasonable to think it may have had two or even three roofs. Were the drains still of sufficent size or did the roofs roll the roofing into drain reducing their size? Did tar or muck fall into any drains causing an area to trap debris? Going back to the 11"s was the drain in this area an issue? Was that why they had problems? Was this drain altered maybe it was damaged or came apart inside the building?
That is the long winded version of it's not the property/location it is something with the building and water was running right to this location it has nothing to do with ground water inflitration or flooding.
