You are better off speaking with a landscape architect to maybe consider a french drain along that side of the house. A good neighbor would have put one in on their side to address this.

The dead grass in the corner is from being driven over.

Why don't you, with the neighbor's approval/help, connect piping to the sump pump discharge and route the output to where it would be acceptable to you?

Yeah, considering that. The issue is that the acceptable place for it to go would probably be into the street, which would involve the drain going under the sidewalk.

And yeah, I really think the dead grass is from the water pool. Not from being driven over.

And also, we really like our neighbors so don’t want to start problems but are a little disappointed they haven’t done anything more to resolve the issue.

Going under the sidewalk is pretty much a non-issue.

Very helpful! Thank you!

A surface drain or (even dug lower) a french drain will not help if you don't have the slope to daylight the drains. And even IF the city allowed you to cross under the sidewalk with a pipe, you can see from the picture that you do not have the slope, nor curb style, to daylight a drain to the street.

Assuming that the city follow ups ok'd the distance the neighbor's sump discharge is away from the property line, and lacking any place on the neighbor's lot for a retention area of the sump discharge, the best scenario (without pics) seems to be to have the neighbor route their discharge farther away from your lot, like into their main front yard so there is more field to accept the water. And if you edge the sod to the concrete (leave at least 1/2" gap) then it will help with some water to not flow onto the concrete surfaces.

There shouldn't be grass there anyway. The rock dry creek bed was set up to deal with the water, and just needs to be extended to the other side of the hell strip, next to the street.

Anything you can do to keep the water from overflowing onto the sidewalk would be better. One, you'll get staining (both from soil and grass clippings after mowing), and two, I'm sure a neighborhood walker at some point will complain (even if it's just water and not a legitimate concern with ice). AMHIK.

When I look across the street both houses have a grade slope down to street. So I would extrapolate that both you and your neighbor have a falling grade in the back of your houses. If so, route both your sump discharges there.

Hi, Do you have gutters on your house and if so where do they drain? I So, maybe you can put a drainage system and tap into where your gutters drain.
