Hello, I am developing plans for a rain garden on my property (see attached), and I was hoping to speak to someone (or even have someone visit) about how I can/should approach it. The challenge I have is that I'm not only trying to handle runoff from my roof, but my property appears to be downstream from several properties' runoff, which builds up in my back yard and flood the yard and my sump/basement. I need help determining the size of the rain garden, and ensure I don't cause any issues with my neighbor. Can you help or can you refer me to someone who can help me develop plans for something that'll work? Thanks! Brandt
