45 plus years ago when I was designing residential subdivisions I would get chewed out for doing this.?ÿ One is a lot corner and the other is a PC/PT.?ÿ These are not small lots and there is plenty of "open space" to be able to adjust lot lines.

I don't understand why anyone would have a problem with this. Please explain further.

Too many unknowing landowners grabbing the wrong one to use for basing improvements.

You can throw all theories of statistical odds, random selection and analysis out the window, the fence guy is going to choose the incorrect one.

Donƒ??t monument the R/W BC, simple. No one really needs it. The homeowner is going to landscape up to the the sidewalk.

A city locally requires every single last point be monumented, doesnƒ??t allow for common sense. Set over 50 rebar caps in an office park, stupidly ridiculous. Most in shared lanes in between the parking lots, who really cares? Put some key points in for the ALTA guys but 25 rebars around an office building, unnecessary in my opinion. Rules like that donƒ??t leave room for practical reality.

Office parks usually adjust the lot lines every project, tried to tell the city that, nope rules are rules. There were 100s of rebars in the vacant fields, half were hit by towner disks over the years. 3/4s of them no longer valid because of adjustments. Like a rebar truck exploded out there.

I'm doing some work to recover a lot boundary in a subdivision that was done in 1960. All of the PC, and PT are coincident with lot corners. When I saw this I immediately appreciated that surveyor. Good work.

Historic boundaries and conservation efforts.

Cadd monkeys, not surveyors preparing subdivision plats. ???? ?ÿ

Can't agree more, how some of these lot lines get designed is baffling. One technique we use is to countersink the PC PT when they are so close to a property corner. It's required that all the "corners" are monumented, but I don't have to make them all visible. Even worse are corners like those on a common line. One of my pet peeves. They will always pick one and fence to it both ways. It's like subdivision designers have never built a fence or something.?ÿ

if you have space to make them one and the same, definitely do it.?ÿ Space is typically in high demand and?ÿ the road alignment is set.?ÿ The lot width/setback control things, not our desire to have 1 corner instead of two.?ÿ I used to be concerned with this 20 years ago but not anymore.?ÿ Set it and move on.?ÿ Around here all corners must be set.

I have a 1958 plat with two lots' back corners shown 0.9 ft apart. Makes even less sense before CAD when you are hand-calculating everything. (And on the streets getting the curve data wrong.)

Monumentation in Kansas Minimum Standards

MONUMENTATION
Unless specifically excluded by agreement with the client, the surveyor shall establish, or
confirm the prior establishment of, permanent monuments at each and every corner on the
boundaries of the parcel or tract of land being surveyed. I

Our hands are sort of tied on this.?ÿ Thus, our subdivisions are loaded with monuments prior to the arrival of the utilities and street paving crews.?ÿ It's amazing how many can get taken out by a skinny little electric cable trench.?ÿ Those guys seem to think that is EXACTLY?ÿ where the cable needs to go.

We once or twice had a subdivision with numerous rear lot lines defined by flags set by a biologist defining some line agreed upon by those involved with wetland ecology, save the whales etc. These were ?¬ ac. Lots and some had as many as 15 rear corners and every single one was in a muck bed. Client almost busted a blood vessel when I told him how much extra those lots would be, but paid anyway. ?????ÿ

I had a client that was going to split up a small family ranch along a common line. The owner is a family trust and the son of the trustees is a local attorney. Really, really nice guy. So I went out with the attorney to lay out the line. He wanted it along the bank of a drainage. We started setting lath and I was gently trying to get him to calm down the turns and points. By then I was very experienced doing this type of work and could tell a cluster when I saw one. No amount of prodding could seem to slow him down.?ÿ

After we got to the end of the lath layout (I was running out) he asked me how long it would take to get it surveyed. I said, well first I'm going to need more rebar and caps, I didn't figure on setting 40-50 caps. The old man showed up, he was elderly and using a cane he took one look at the line and exploded; "Do you know how much all these brace panels are going to cost?" He's pissed at me!!!

The attorney stepped up and told his dad that I've been trying to stop him so he turned his attention to the son. Anyway the 40-50 points turned into the 2 end points and two in-between points to cross the drainage. A few POL's and I was out of there in an hour or so.?ÿ

What always got me with this kind of stuff was years ago, when staking the roads or right-of ways we had to set up and turn deflections to keep it going. Now I have a ten foot back site and need turn it to a pt 400 feet up the road. That'll kill your accuracy for sure, specially being the old tape and transit days, no data collector. So now we had to set out additional back sites as far out on tangent as we could see in order to maintain some degree of accuracy. The design engineer couldn't have cared less, but always complained when we couldn't keep the staking within budget. Sure, there were times when it was unavoidable, but in most cases he could have brought the pc and pt together a lot quicker in the office than what we had to do in the field.

When working for the Department of Transportation I would have to stake out tangent lengths of 0.14' between curve points. Just dumb!

Not having them be the same potentially adds some confusion that doesn't need to be there.

This reminds me of the first PLS I worked with though-- he really wasn't a fan of nails in sidewalks, especially nails in joints.?ÿ I was sort of indifferent at first but now I see where he's coming from-- they do look lazy and kind of cringeworthy.

I'm not sure how old the monuments in this picture are but I think I'd try to set just about anything other than a nail.

I have a set of mile marker posts I drive by now and then on an interstate highway. They have mile marker signs, sometimes there is an equation station marked with a back and ahead sign next to each other, one set is difficult to unsee. They say something like BK 186.56 Ah 186.55. Go figure, do they really need something like that as a milepost sign?

We call that a 50-50-90.?ÿ

That is it is a 50/50 statistical chance, but will be gotten wrong 90% of the time.?ÿ

This is adjacent to the next lot so there was no reason NOT to move the property corner to the PC/PT.
