Hi all experts and DIYers, this is another project what I am taking in parallel with another project which I had posted a few weeks ago ( still in the middle of that project because of busy work schedule and wet weather condition).
Attached are the pictures related to this project.
This is my plan:
In the area, where I have been putting bins all the time, thinking of planting 3 or 4 Pencil Pine trees. Bins can be taken somewhere another place. I will have plenty of pebbles extracted from previously laid ground (where I am going to use White/ Black pebbles) and I can use them in this area or I can use mulch. I have a big tree that always makes the driveway dirt, especially after the rainfall. I am planning to trim the branches as I go. However, I noticed some damn ( or always wet ) areas on one end of this area. I have attached the picture. The reason is, my neighbor's house is on higher ground than mine and the water comes down to that area and cannot go anywhere.
Is this an issue? I am worried now. The house is 28 years old now and I am sure this has been happening for a long time ago. If something had to happen, it would have happened by now. This is just my assumption. But still, I am worried about water seeping through. Or I might need to think about sorting out this water flow problem.

Always wet ground (worried about it now)
