Better get it right or someone will set a new monument 0.12' away. Or better yet, they will just put a new punch on your brass disc, but no LS #, so it will look like you couldn't make up your mind.
That always makes me happy.
Holy
OOPS...
I meant NON-Trivial...your milage may vary.
Obviously it's pretty meaningless in the DARK timber with a several mile traverse to base it on, much more meaningful here in GPS heaven.

I amend my comment
Brian is a straight line the same in a plane sense as it is in a geodetic sense?
Since its a clean Section 16 that's never been subdivided I'd try to convince them to not screw it up by doing any aliquot part subdivision. Especially if they are going to survey the new parcel. Aliquot parts were designed to allow deeding and subdividing without surveys as cheap as possible. If they are going to have it surveyed figure out where the aliquot part should be (what they are gong to sell). Mark the corners with good sturdy monuments. write a good metes and bounds description and forget setting the C4 unless it is one of the required corners. Even then I wouldn't call it a C4. Doing so just encourages every surveyor for the next 200 years to reject it, move it, challenge it or put their own punch mark on it.
At this stage in surveying and land subdivision dividing by aliquot parts or protraction shouldn't be allowed. Its proven out over time to be the biggest cluster imaginable.

Well, since you brought it up, "minuscule" only has one "i."

Constant something.
Leave it to surveyors to make it difficult.
If your original set it right, if your not original, retrace it as it was done originally. Manual covers both scenarios and when to use each. Granted we are allowed the professional judgement by our state to interpret this, as each situation may contain varying levels of evidence. No cookie cutter but close.
Thank you. I needed that. A little slap of reality once in awhile is a good thing.

Exactly what part(s) of 2-13 and/or 3-114 are you having trouble understanding?

Brian, Is it doubtful by common practice:-@:poop: , legislative action:-/:pinch: or judicial decree:rain: :'( ? I thought Idaho instructs surveyors back to the "Manual," as Oregon and Washington does.
A quick google on the board website has a few links that appear to show these redirects to the Manual. But this was a quick search at best and I don't work in Idaho.:-)
(COUNTY SURVEYORS)
31-2709.SURVEYS MUST CONFORM TO UNITED STATES MANUAL.
55-1608. Professional Land Surveyor to Reconstruct Monuments. (1) In every case
where a corner record of a survey corner is required to be filed or recorded under the provisions of this chapter, the professional land surveyor must reconstruct or rehabilitate the monument of such corner, and accessories to such corner.
(2) Any monument set shall conform to the provisions of section 54-1227, Idaho Code, and shall be surmounted with a cap of such material and size that can be permanently and legibly marked as prescribed by the manual of surveying instructions issued by the United States department of the interior, bureau of land management, including the license number of the professional land surveyor responsible for placing the monument.
As it applies to being allowed to use our professional judgement in finding and interpreting evidence of good faith efforts:
Common practice - by many - yes. Legislative action - no. Judicial decree - absolutely not. Actions taken against private surveyors who have used their professional judgement by the licensing board (comprised mostly of engineers) - absolutely. Trust me, been there done that over the past 3 years. 🙁

I also have a simple question. Who cares?
Curvature in this circumstance, could amount to very small difference. So, to heck with it. Simple plane Cogo at BB int is the end of it.
To a farmer, 0.2' is adequate. Especially if you hit a rock!

As soon as we perfect the Karoly Intercontinental Technologies Corporation "steel melting laser beam, boundary marking" they'll care about the 2 tenths, believe me they'll care!
The Engineering Department is telling me they haven't figured out how to make a laser beam follow a curve yet, but when they do, watch out!
Setting ORIGINAL C¼ - Trick Question
Now that's funny.
But you weren't supposed to reveal that to a Texan. We may have to come and confiscate your copy of the Manual now.
:good:

Well, sure. "they" care. But your premise on what "they" care about is all wrong, and it has nothing to do with a precision aspect. What "they" care about is whatever gives them more land. Your first question should always be where the client "wants" the corner to fall, then you commence to use the appropriate equipment to provide them the product they desire (and pay you for.)
I would and have calculated the position on the latitudinal arc and that is what the BLM asked (required) me to do when performing surveys to be approved by them.
However, the original surveyors likely do not calculate the corrections but used the redbook or its predessesor tables which only give corrections to the parallel in one link increments!
