do you really think they'd post a map of underground gas pipelines on the internet?

Well if you click on the link to the story, you will find the map that you want. From what I can see the pipe that they think is high risk comes into town on the right side of the old hwy 84 onto 4th street and ends close to Lowes. So I dont think Sunset east homes are very safe

"The segment in Livermore skirts the city's southern edge, starting around Greenville Road and heading southwest toward Highway 84, Brown said."

It looks to me that the majority of it runs through Sycamore grove and under the vinyards close to Arroyo Rd.

One line goes up Isabel though... that's creepy.

The one near Isabel runs through the backyards of the houses across the street from my house! Just found out last week, nice.

I believe the pipeline listed here is the one in the in the backyards of the houses along Joyce and Lucille that runs parallel with N. Mines between Patterson Pass and East Ave. It is basically follows the path of the high tension power lines.

That map shows it crossing Mines and South Livermore Ave. that's about 3 miles away from those streets. It looks like it goes right under Dunsmuir though! Did you hear that Semi-Charred?!!!

Great, the poor 911 operators are now going to get flooded with dozens of calls per hour from idiots saying they smell gas, when the truth is their dog just farted...

Sounds like people are talking about more than one pipeline. The biggest diameter pipeline is in a utility right of way, and it is NOT under any backyards at any point. Nobody would allow construction on top of a large diameter gas distribution line - it would never be allowed, EVER. Even 30-50 years ago.

So these folks who are saying they have a line in their yard are confused or mistaken - it might be a smaller line,*behind* their yard, again, not IN int, in a right of way, but it is not the big diameter line referenced in the story; that one, line 107, is way south of town.

I've actually seen it/walked over it. It is clearly marked, per regulations, when it is close to a surface crossing.

Anon --- You are wrong (As usual)– I have a good friend that lives on Joyce. The houses along Joyce and Lucille St’s have double size backyards with an easement where you cannot build any permanent structures or dig more than 6 inches in the ground. The easement is there for both the power lines AND a major gas pipeline that runs through there. There are markers at his fence line to mark the pipeline and PG & E comes through about every 6 months to a year with sniffers to checks for leaks.

That may be but I think we were talking about line 107 as per the map in the article. That line is no where near Joyce st.

Right, so if that is also for gas and not just the transmission towers, it is a feeder pipeline (the ones shown in red, but not a large diameter line like the 107). And as I said, they allow no construction over it - and it sounds like the line is located at the fenceline, not entirely within the easement?

I'd be very surprised if the line is entirely within the easement on his parcel and not just outside it, because there are lots of people who have installed additional structures and other things in those easement areas. They are visible from the satellite views.

Typically I would expect that the easement deeded to the property represents the aerial "footprint" of the transmission tower and guy wires (that's normally the case), plus a small area on either side. Generally in the language of the deeded restriction what is granted is described in terms of distance from the centerline of the structure or installation. And hence that is why they cannot build permanent structures there. It doesn't automatically mean there is a subterranean pipeline within their privately owned, yet restricted property. For instance, it is common for easements for aerial lines to include restrictions about swimming pools and other types of improvements to the portion of the property under easement.

Anon -- I cannot believe I am wasting my time responding since obviously have no idea what you are talking about.

I spoke with J and here are few details;

From the back of his house to his back fence is 150+/- feet. The easement is from the back fence toward his house either 120 or 130 feet (he can’t remember which one). The high tension lines are all within his property line along the rear fence. The gas pipe is about center of the easement or 60-70 feet from the back fence and about 80-90 feet from the rear of the house.

This summer we were in his backyard having a cold one when PG&E came to test the gas line I asked him about the line and he called it a “very high pressure” I thought 36”(I could be wrong there) line and that is why they check it so often.

Hey naes -- I looked at the map too and my thought was the pipeline route appeared very general, almost pen stroked in. Knowing the pipeline along Lucille and Joyce I thought it was possibly the same one.

Hey naes My bad --- When I saw the map I was thinking N. Mines and pictured the road it crosses as First St. That would put it right there. Now that I look at it again it is obvious it is Mines and Tesla area.

Ok, so 20-30 feet in from the rear property line, wow. I wonder if its consistent the whole length of the line, because that goes all up the way up through town in N Livermore, at least the easement does, not sure if the line diverges someplace.
