Who is responsible for the sewer/street drain in front of your house?

I have heard of great disasters where people basements flood because of a clogged sewer drain in the street after a prolonged rain . The local municipality is usually supposed to keep these clean so they can accept rainwater runoff, but as you know, this is not a priority for these municipalities.

If you purchase a house with a sewer drain in front of it, it would be wise to keep out the leaves and debris yourself. I know it shouldn't be your problem, but if your basement floods, or your garage turns into a swimming pool and it causes damage, the municipalities usually turn a deaf ear. One fellow AR person on Long Island had this problem, but she did not win.

Keep this in mind especially if the house is near the water, as these areas are more prone to street flooding. Thanks for reading! -Ray
