My son is a Registered Professional Land Surveyor and while he was up last weekend, I showed him this thread. With lots of eye rolling and shrugging, he said these are typical things RLS face. Surveyors may enter land, it is not trespassing. He has had to explain the law to deputies called out many times. A professional tries hard to be a professional at all times. Sadly, as in any profession, not all do.
My son tells funny stories of doing a line survey for a fella. The guy gets home from work and calls the Engineering Firm office. "Thought you were going to do my survey today. What's up?"
"Your survey was completed, sir". "Staked, flagged and marked".
"There is no evidence whatsoever. No flags, no markers. The neighbor must have pulled them all up before I got home. You'll have to come back and do it again."
"That would fine, sir, we'll see if we can schedule another survey crew, but of course you'll have to pay for another survey. Obviously, these guys cannot come do it again for free."
"But my neighbor stole my first survey, in effect. What I am supposed to do?"
"You'll have to take that up with your neighbor, sir. Do call us back if you want it surveyed again. Have a good day, sir, and I hope it all works out for you."
