I, too, get cornfused easily, but it seems like you're trying to fix something that isn't broken?

I had a County Surveyor get heartburn one time over my labeling two lines Basis of Bearings. The two lines happen to have been defined by the two CCS83 control points that I started my traverse on and the two I ended it on. The Basis of Bearings was CCS83 and not two separate record lines.

The point is that two BofB's are not going to be well received.

From the snippets posted I cannot tell exactly what you are trying to say.

The Surveyor's statement is the way to go. Write up a paragraph saying that you retraced Deed XXX by rotating to found points A and B and so on. Be clear and specific. Make it easy for the next Surveyor to follow your map.

Gary Kent had a good presentation at the Conference on Surveyor's Reports and his take is that you can save yourself a lot of headaches by making it easy for the next Surveyor to understand and accept what you have done.

I cannot ever remember looking for the “basis of bearings” statement on a map. I do a lot of our company’s research in order to determine the fee so I am guessing I have looked at in some detail 20-30k.

One thing I look for is the comparison between the surveyor’s measured and the previous record. From that we can determine what lines were held per that record. If deed distances are held but not deed bearings then I look to see if the record deed angles were held.

In this way the deed line from which the other calculated deed lines were based on becomes the “basis of bearings” that established the other deed lines. There may be another line that the surveyor used to create his “Basis of Bearings” statement. It could be based on CCS, another RS or anything appropriate.

So in this way you have the BOB as stated in the BOB statement and then another “so called” basis of bearings for the held deed lines. You could have a third so called “basis of bearings” if you held a record angle from a Record of Survey to re-establish the position of a monument now destroyed.

There is usually a need for a brief explanation as to how certain lines or points were established so notes to that effect are good. But if I see that a number of lines contain bearings and distances that match a particular record verbatim then we know that Is the BOB for the map and the lines were held per that map. We should not need a note for that. It’s obvious.

What kills me is a map with little or no record data or record data with no reference (record). I find this on maps by surveyors well past the year 2000. I wonder how in the world did this map get recorded? Who checked it? Even some past 2010 have minimal info.
