Can anyone tell me what this is for and why? See pics. It was placed about 30 ft onto my property and not on my boundary line or corner. I requested no activity from any surveyor. It has occurred likely in the last month. It says "not a property corner" with the triangle symbol with dot in middle

The list of possibilities are endless, including having not been set by a surveyor but by an employee of some utility.  If so, don't mess with it.

It looks like a control point.  Most surveyor's will knock on your door and say hi before setting one in your yard, but sometimes no one is around when we're doing our work.  If it's within a few feet of the road it may be in the road right-of-way and they may have felt that marking the stake to indicate that it was not a property corner would be sufficient to let you know what was going on.

A control point is just a reference point for the surveyor to set an instrument over or take a sight on to establish their orientation. Often we will need to set our instruments on adjacent properties to get a line of sight to a property corner or other improvement that needs to be surveyed. Since they marked it with a stake it's likely that they need to use it again in the near future so please don't remove it.

@stephen-ward        thank you for answering.
Some background info.....

This area is at the rear of my property and near the rear property line of the next property off a separate roadway to the west. This area is not in the sticks, roughly 2 miles off I95. The lots are 4 to 8 acres or so in the area.

There are no utilities at the rear of both of our properties where this marker was set. The utilities are 800 ft to the front of mine and the neighbor's lot at the roads that serve us, opposite directions. It literally is nowhere near construction or utility ROW at all, at the back of our properties.  This marker lines up with no property lines of mine or the neighbor and it is on my property about 800 ft from my house. I am home always and my dog would alert, and anyone coming to the house to get permission would have to pass "do not enter" signage and "beware of dog" signage, about 25 sets all around my property. So they had to come from the other or back of the property.  They trespassed to install this stake, actually right next to one set of those signs. It does look professional though doesn't it? Just trying to figure it out before knocking on doors. Most of the neighbors back there are tenants and a bit inhospitable last time I ventured to say hello bout 5 years ago.

It is a control point for construction work. I know at least one person (not a surveyor) in NY State that starts control at 9000. It has nothing to do with your property boundary but is important to the construction crew.

(In my world ) the triangle means that it's a control point, not a boundary point.  I'd also assume that there's a hub stake/tack, rod, nail, or something else at the base of the lath, which is the actual control point.

As far as who set it, I'd assume a survey or construction crew.  And if you've already talked with someone about having no points set on your property, it might be time to have another discussion.

The guard stake says "not a prop. cor" right on it.

I also use the delta symbol to mean "control point".  9000 for a point number is a bit expensive for me.  I go with the cheaper first 100 points.  Usually get them on sale at Walmart.  Packs of 100.  Sometimes 2 packs for $5.

A control point is a reference marker set by a surveyor for their own measuring purposes.  Like if you wanted to measure 40 feet with a 25 foot tape, you might put something in the ground at 25', then measure from there another 15'.  Except it's more complicated that that.

In Idaho the surveyor would have been required to give you written notice prior to entry, including notice of the temporary point. There are some government crews who are exempt from that requirement.

@jph I don't want to be  jerk if they are not going to be traipsing to it much. Why couldn't it be referencing just as well on their  property?

@jph I think the OP meant that they had not contacted anyone to work on their property, not that they had requested that the surveyors not set anything on their property.  Can easily be interpreted either way.

Ah, I see now.  Weird how I read it that way.  Wonder if anyone else did too.  Thanks

I'm guessing there's some construction about to happen, utility work, road work, something similar.

@jph I did as well on the first pass. Then I reread it because it seemed a bit awkward and saw that it could be taken either way.

I'm curious to see what's under the leaves.
