Potential Standing Water Issue or Inspector Overreaction?

[Mark S.]

Inspector says potential standing water issue during heavy rains.  Top pic shows his concerns and are the “before” photos.  Turnkey company “made the repairs” in the bottom two photos by installing gravel so that water supposedly easily travels away from the house (encouraged by the slight slope from back to front of the home).

Should I be concerned?  I’m days away from my rate lock expiring, loan is clear to close, turnkey provider saying it’s resolved, and inspector who was supposed to go back out to check on it for me is unreachable. 

Thoughts?
