Recent record rainfalls in other parts of the country got me worried about my own property. Each spring, when the ground is saturated, the storm sewers just can't keep up and my front yard floods. Were we to receive one of those deluges, I'm afraid my house would be underwater. So I sent the city an email, to see what could be done.
One thing that can be done is the storm sewer casings can be removed so the engineers can see what is what.
One surprise was, while the inputs were obvious, the output was not. My neighbor across the street had seen some storm sewer maps once upon a time and said those showed the storm sewer drained to the east. But actually, it drains to the west.
There is a utility easement on the north side of my property - and presumably on the south side of the property to my north. The sight line makes it look like, if any further digging must occur, it will occur on their lot, not mine. I have shrubs planted on the easement, not always a good idea since the utility people can rip up an easement at their discretion. Let's just home it doesn't come to that.
