8 or 9 stories? Doesn't that fall way short of the recommended 100m minimum height?
I started this thread because I was considering a 15-story car park, and the responses were in agreement that it wouldn't be enough:

Yes, more than a handful of people have died with the last year or so have jumped from parking structures in downtown Santa Monica. Just google "Santa Monica Parking Structure Suicides" The area sucks for parking but there are a few tall ones that are like 9 stories high. I plan to jump from a bridge. It's 144ft so less than half of 100 meters and it's on to concrete. There have been no survivors, but for others, it's too short a distance. From what I read, the way you jump is the most important. Being upright changes the survival rate from an otherwise deadly fall. I haven't done a lot of research on it but I'm pretty sure the majority of people stories you find of people falling and surviving were feet first and had a lot of damage done to their lower region.
And you can probably find people have died from even shorter distances, but I probably wouldn't do anything less than 8 stories. Saw in a trauma/medical book that at 70ft chance of survival is about 90% for the average human. So your own measurements matter a bit. I think the suggestions you read are just taking the max precautions like that the person jumps feet first on to a surface that isn't concrete and there's an ambulance on standby lol. Also a lot of it saying rather you'll die immediately or not, but it's not like you'd be conscious or awake if you didn't die on impact and took a few minutes.
People slip and fall 2-3 feet and hit their head on a table or the ground, and become unconscious
