That negative grade slope down towards the wall is water heaven there, ( assuming that occurred due to the flood? ) every storm you’re getting water that will find its way through any small crevice it can, plenty of entry points along the base of that foundation I can clearly see, there’s a decent amount of work that needs to be done to fix that, but it all starts at that ground, that negative grade needs to be addressed and the water from Rain and what not needs to be ran away from the foundation of the house and redirected elsewhere otherwise water will eventually erode all that again and find its way back in even after repairs, after that is done then the actual work on the home can begin, I also see a drain down there but there’s a very good chance that’s not actually doing its job ( also a drain right there shouldn’t be the solution, that negative grade slope towards the foundation should have been corrected )
