I was out tying ROW monuments today and one of my calc points took me to this fence corner.?ÿ Locator wasn't very helpful with all the metal in the area and the calc point landed right on the irrigation box.?ÿ At first I was like great, these clowns HAD to put the valve box there??ÿ I thought for sure the monument had been destroyed and was about to move on to the next one when I thought what the hell, maybe the lid will come off.?ÿ And then...

Mr. Strand,
So, did the monument fit the record position?
Or did the construction guys do like a wall contractor was doing to me? I had set 1" iron pipe at the rear corners of the lots per a tract map I had done near my home.?ÿThe developer had decided to build CMU walls around the perimeter instead of the typical wood fence.
I was driving home one day and noticed a contractor working near one of the lot corners of the tract. I stopped and introduced myself and watched him insert, into the freshly poured footing for a wall, an 18" long, 1" iron pipe with my tag in it.
I asked if he had tied out the position of the pipe in order to set it in the same location. He said no. His company never did that. He was told that the existence of the iron pipe was very important and to always replace them if the dug them out. (!?)
I checked the remainder of the tract and found about a dozen more where my friend had done me this favor. Most were out of position by a half foot. I had to amend the map to show tags in the wall or footing instead of the 1"ers. I busted up a bunch of the footing getting my pipe out of there.?ÿ
I was paid for the additional effort. I just wonder how often this sort of thing goes on. That aluminum disk looks as if they took care to leave it undisturbed, but did they?

Some of our most often used long term control points are set in irrigation boxes.?ÿ
That monument had to be set in the box, rather than the box being set over the monument.
Happens often, one way to know when it occurs is to stencil the cap with the lot lines.?ÿ
I helped a friend do some surveying in Las Vegas some time ago... they have section corners in valve boxes in the middle of major intersections.?ÿ I've never seen a place where the monumentation was so well preserved and documented.?ÿ Makes a great argument for mandatory recording states.
I just wonder how often this sort of thing goes on.
Happens all the time. My good friend was putting up his fence, and he did the same exact thing. I just shook my head.

Same friend...his front corner was installed inside the water meter box...of course the fence builders pulled to a rebar set in the ground a foot or so away, it was for tying off a support for newly planted tree.
I showed up on this guys front porch, looking for a bench mark. The guy comes to the door and asks; what's you fellers looking for? "The NGS claims that there is a brass cap, set in your concrete step here." He say's; yeah, it's right here, and takes us inside his house, pulls a piece of his fireplace off, and show's us the brass cap...
He had remodeled the front of his house, and preserved the mon for anyone that wanted to use it. He was surprised, that we were the only ones to come sniffing around, in all this time. We sat up the level; set the rod on the cap; and proceeded to level out the door. The bench was still in good condition and matched VERY close to the elevation we measured.
God bless the good people on this planet!

I don't know how many rodpersons (my green self included) would locate the grounding rod next to a utility pole for a property corner.
and to @jerry-attricks comment: I've seen the aftermath more than once of a fence builder, utility company pole/transformer/service box setting crew that would pull the rod place the pole or whatever then stick the rod back in the loose dirt "right where it was"
Found two of my bars yesterday at the edge of concrete poured around chain link fence corner posts.?ÿ The pipe corner posts were precisely where the bars had been.?ÿ A third bar was found directly below the fence where it was supposed to be.
We were working staking roads on a new subdivsion that I had recently pinned. The power company guys were laying in their?ÿ lines, and I noticed they had one of the corner pins laying on the surface. I asked the guy working there, and he says "Oh yeah, when we get done here we will put it back", I said did you reference it before you took it out? "No" says he. Well how are you going to put it back? "Oh, I remember where it was" says he. I told him do me a favor and just toss it. Whether he did or not I don't know.
So, did the monument fit the record position?
It's hard for me to say actually.?ÿ This project was started before I came on board and the only work I've done on it is in the field.?ÿ So far the monuments are landing within a few tenths of the calculated points I was handed.?ÿ An odd one might land within a few hundreths so maybe that's a sign the boundary is still being tweaked.

I wondered that at first but it was kind of under the lip of the box and there's no way you could pound a 2-foot bar in there straight and then somehow get a hammer in there to tap down the cap.?ÿ It still made zero sense why they had to put the box right there though; my pictures don't show it unfortunately but there was tons of room behind and around where I was standing.
I also like the generous interpretation of the ROW by whoever installed the fence. ??? There was at least a foot, maybe 15-18 inches between the fence post and the pin.?ÿ Of course, the fence could have been there first, but the ROS where these pins were set is dated 2014 and the fence doesn't look particularly old either.
Survey monuments are in motion. Not just natural causes, frost heave, snow, sunshine, rain, erosion, little old ladies, in their flower bed, Fifi tied to the rebar, mowers, bushogs, trees that fall over, but power angers, all the stuff above, trucks, trenchers, water lines, cows, horses, goats, crustal motion, lightning strikes, it's a fundamental fact. Monuments move.

Need to cut a hole in his roof and get a GPS on Benchmark there.
