Try running a test. Put a thin layer of pebbles or gravel at the bottom of a clear container. An old drinking glass or a clear plastic disposable one will do just fine. Put on top of it a handful of soil dug from your garden, gently press it and then pour a glass of water on it.
If your soil has become hydrophobic you should see the water stay on top and percolate in the bottom layer only very very slowly. On the other side if your soil is too permeable it will go straight to the bottom in a matter of seconds.
This will give us something to work on.
Another thing you may want to check is water table levels in your area: it's likely your County has publicly available records for it. A steadily dropping water table is very bad news for any kind of soil and, unfortunately, it's happening in too many places.
