My sideyard sits below my neighbors backyard, so when it rains heavily (12" in the past few weeks) I tend to receive alot of runoff. The water then hits my driveway and settles in my backyard. I have put in a rain garden in my backyard where the water tends to settle, but it can only handle so much. I have some ideas to try and limit the amount of water getting to my backyard:
1. Would it be useful to create a dry creek bed with landscaping, or am I just making an easier route for water to get to the driveway and take off?
2. Put in a couple of catch basins. The sideyard also sits below the street level, so I would end up gravity draining water to the backyard unless I used some type of pump system.
3. Build another rain garden.
Any thoughts or ideas would be appreciated.
