In simplest term, material, by legal definition means a point at which those two things can no longer be called the same (because they have s significant, or material impact elsewhere).
Let's look at this little more closely - in building terms, when it comes to encroachments and setback lines, most items, even in tight areas are looked at within a tenth. (Zoning, planning, permitting) you are only dealing sub tenth in highly packed downtowns or high-rise buildings when you have to deal with fitting steelwork. Even in older downtowns, no-one is likely to have an issue over a tenth.
So if you are dealing with 0.07' and calling it the same thing, the risk of creating a problem by calling them the same thing is negligible, or immaterial.
0.5', in same downtown scenario, very likely material. In minimum size subdivision lots, probably material, in large agricultural or open space lands, probably not material.
Another way Material is described is "likely to result in a different outcome" (when making decisions based on the results).
For example, is it likely to result in a land title dispute? A utility suddenly not being covered by an easement or a ROW? Encroachment likely to cause a dispute? (Does anyone care of a zero lot line building is 0.05' over or under? How much time would you have to spend surveying a good sampling of a building facade to determine if it os 0.05' over or under, and how high does the precision of your PL need to be to have that level of certainty???
Maybe others have had to do this, only time I ever had to worry about something this tight was when fitting prefab steel together, or setting up a control network.
If we had accuracy standards for different types of surveys, we could conceivably have some guidelines of ranges within which something would transition from immaterial to convincingly material, or expressed as risk scales.

Re: RS vs. CR What are the differences?
I agree with all of this 100%, and I can't count the number of times I've said it myself. The County Surveyor is NOT the survey police!Ian Wilson wrote: Mon Aug 28, 2023 8:30 am Material discrepancy is in the hands of the surveyor who submitted the map; NOT the County Surveyor. What may well be significant in downtown Big City may be INsignificant in rural areas. Is 1:1,000 significant? 1:100? Not my call as CS.
We can't refuse to record any document sent to us.
All we CAN do is put a comment on the map detailing the perceived deficiencies. No more, no less (the latter as your previous County Surveyor found out, Phil). That includes potential comments about the methods (or lack thereof) shown on the documents.
We are not the Survey Police. We ARE editors of the map in the same sense that a writer submits a manuscript to their editor of review, clean-up, suggestions, etc.

Re: RS vs. CR What are the differences?
Interesting concept here, as notes are suppose to reflect the "facts" as outlined in the PLS Act. Not ones perception that a potential alternate position doesn't relieve a surveyor to file a RS map.Ian Wilson wrote: Mon Aug 28, 2023 8:30 am Material discrepancy is in the hands of the surveyor who submitted the map; NOT the County Surveyor.

As for the original question reflecting 0.07' out of position, I have to ask LS 8750 if he understands the size of the original iron pipe?
Think about it people, and why the old timers set a 6x6 post? As Chuck Korayan emphasized in his seminars it's an ego issue, and you can measure better than someone else, period. Set a 4" iron post and move on, lol.

Re: RS vs. CR What are the differences?
Am I being strong armed into being one of those M&R Benson types by a County Surveyor?
And the phrase "COGO is just a tool, not a boundary law principle". Did that come from some LSIT practice exam book?
What if by chance COGO and occupation fit so well that the surveyor feels his/her presence to be a waste of time?
Would that indicate a convergence of COGO and "boundary law principle"?
We do we have courses and distances? Why do we have maps?

I believe the general purpose of a boundary survey map is to demonstrate the relationship between COGO and occupation.LS_8750 wrote: Thu Aug 31, 2023 10:48 am What if by chance COGO and occupation fit so well that the surveyor feels his/her presence to be a waste of time?

If that is not clear on the face of the map then maybe you could add some details
