Problem getting backyard run-off to the street

All the run-off from the back half of my house (roof area, backyard, pool cover, two sump pumps) all converge to a point at one rear corner of my house. It gets there rather efficiently and heavy snowfall and spring rains have made this apparent!

The problem is, from there it is designed to run about 100' along my property line to the front and onto the sidewalk and the street. Both properties slope downward to the property line but, over time or just due to the heavy rains, the slope has failed and the water doesn't get to the street. Kills the grass and makes for miserable lawns.

All of the utilities are buried in this area, so french drains or any digging of any depth is not wise. The line is also about 6' from my house and there are casement windows in my basement that are nominally above grade.

Right now, I am dragging a 100' 4-inch corrugated pipe out after rainstorms, but would like a more permanent solution. Aside from the utility concern, if I buried the corrugated pipe just below the surface, it still would be below the sidewalk and wouldn't drain.

What are my options? Dry creek? Is there something I'm overlooking?

Even though the utility lines are underground, there is still a chance that you can install some dry wells or other drainage. Do you have any plans that show where the lines are located?

Have had them marked - 2 gas lines, power, phone, cable, and water to the house on the side PLUS the neighborhood gas and water mains run through the front. due to the proximity to the house, the assumption is that depth is shallow and unreliable. At best you are talking about careful hand digging as opposed to trenching.

If I understood you correctly, you shouldn't have to touch the front. Hand digging one or two holes about 4 feet around & 4 feet deep might be enough. In other words, instead of running the water to the street, you would be dispersing it, in the back yard, underground. Some pics of the yard might help.

Pictures right now wouldn't help. It is dark. I wax poetically by the glowing light of apple vision.

The concern I have with the direction you are going...the rainwater coming off my yard and neighbors yard, is enough to saturate this ground as it is; it's a two foot deep mudhole at this point. Then you add the pool cover, the roof catch, and the two (yes, count 'em two) sumps and there's been, to quote Hank Hill, a dang gum lot of water out there. Throwing those into four foot rainholes I think is just going to accelerate the process of getting it back into the foundation drainage system which is functioning fine. Just don't think the objective it to get it circulating in an infinite loop in the sump system (unless it just happened to be diverted to my sewer pipe but , no, I'd never do that).

The idea would be that the dry wells would replace the need for the pumps. If you don't think that will work, the only other way I see is to move the water to the street with an underground pipe. I figured that it's far less work to go with the dry wells.
