Just wandering back from the pool today, I noticed a swatch of dark grass crossing our lawn. It ran right up to the gas meter, connecting the our house and the one next to it.
Why? Is the gas line warm? Does it leak?
Just curious.
The gas line probably condenses moisture on the length of the pipe, and the grass surrounding it draws from this.
Are both houses on the same property? If not, I doubt that the plumbing code would allow them to share a common gas line. I’d guess that the line should be a straight line from the meter to the main.
Is there a depression in the dirt there, or a tree overhead?
-
If it leaked it would leak from one or more points, not from its length, and if leaking gas caused grass to get greener, it would be greener is one or more spots, not in a line.
-
If the gas line caused moisture to condense on it, the moisture would have to come from the surrounding earth, thus drying it out, which would generally not make the grass grow greener.

Most likely explanation: When they put in the gas line they dug a trench, placed the line, then replaced the earth. If they did this, the earth over the gas line would be less compacted than the earth elsewhere in the lawn. Grass and other plants generally grow better (and greener) in loose earth.
They probably used a different kind of grass seed than the rest of the yard when they seeded the earth over the trench.rye and bluegrass mixed are a popular combination here. the rye comes on early and the bluegrass later.
