Water coming in around foundation when it rains
Have you checked your gutters. Every time I end up with water in my basement it is the result of some issue with my gutters. I have a lot of old trees around my house and during certain times of the year it is impossible to keep them clean (I know I need guards). If they back up the water pours over the sides and then builds up near the basement walls and eventually seeps inside.

Also, make sure the downspouts are all still attached and if needed get some extensions to send the water further away from the house. 

Also, check the grade of the area surrounding the foundation. Make sure that there is a least a small slope away from the house. If the rock bed is too high - or if you have some kind or plastic underneath to prevent weeds it might be preventing the water from draining properly.
