PLSS question for those of you in recording states
"Not uncovered this survey."
In Florida that statement would get you an audience with the Board of Land Surveyors. 😎
In Idaho that can be a career ender. We recover and LEAVE evidence..
That new survey rests upon the controlling monuments. Not visiting them and at least verifying that they are undisturbed (and have not been reset) is negligent. Unfortunately, "Found Section Corner, May 1992" on a 2009 record of survey is not uncommon around here.
Depending on locality and where the actual mons are located, I would be measuring them again. In busier areas with more development and frequent road upgrades it's not uncommon for monuments to be disturbed, blown out completely, or reset within a year's time of recovery.
Edit to add: a monument recovery note should include everything about the monument, from size and material to stamping to whether it was in a case or not, to how far up or down from grade it is, to its condition. If it's 2 feet off road centerline, note it. If it's at the base of a tree, note it. Not including all that information is just...lazy. I have to get on some of our crews constantly about this. The smart ones understand that all that info makes their next recovery job easier.
All this depends on timing. Do we go out and check corners when we sign a plat. Nope!!
Normally a county subdivision takes a year from start to finish. Section corners may have been visited in May and the plat signed in Dec. So it that wrong, has the monument been disturbed?
Rare but possible. If you stake a lot on Friday and sign a plat for the lot two weeks later should you know if the pins were disturbed during those two weeks. Or even a few hours, what's the time limit? Anyone know?
This question has been debated endlessly, the board never came up with a good answer. The state and county sure don't want you digging through pavement or concrete each time you wish to tie a monument in the middle of a road cause you have a new survey 2 months after the last one.
Okay, lets take this scenario a little further. Say I tied all of the government land corners for a section 10 years ago and have a robust control network in the area. Now lets say I go back this year and find several of the monument destroyed but the control is still good. I would say that based on the BLM manual these monuments are merely 'obliterated' and that my ties are the best evidence of their location original location. Using the rational for reasoning that I need to retie every monument every time, the monuments would be 'lost' and my old ties would not be evidence of their location. If the monuments were merely just disturbed during the time between the original ties, wouldn't the original tie be closer to the location of the 'undisturbed monument' and thus better evidence?
