In the following only slightly redacted tract map excerpt, what does the "(R)" after the bearings for lots 113 to 116 mean?
(R) after a bearing implies that they are radial lines to the curve.
Probably means they are a radial line. You can think of them as being segments of "rays" extending out from the radius point.
Typically used because a curve is non-tangent to the line.
Lot Line 116-117 Is Nor Radial, Tho Marked As Such
Lot Line 116-117 is parallel to the radial line at the P.T. of Lot 116. I would say the map maker inadvertently carried the R over.

Radial meaning they point at the radius point.
(R) = Record data
(Radial) = Radial line
> Radial meaning they point at the radius point.
You're right, of course. But technically (by definition) radial means they are "radiating" out from the radius point. But I'm with you, in that I wouldn't object to calling a bearing that goes toward the radius point "radial" either. On a plat, we often put the bearing in a more convenient and/or consistant direction, and that is what they did on that plat.

What? How so?
Lot Line 116-117 Is Nor Radial, Tho Marked As Such
I have to agree with that, but the bigger issue is why not make the PC the lot corner, I can see that fence getting built 4' over;-)
Thanks guys. They're indeed radials. I was guessing that, but did not know for sure. You guys confirmed it. Adding up the bearings (street + lot side) and having them come out to 90-degrees appeared to confirm that as well. Interesting how some of the curves are described by mentioning only the arc and length, but not radius. Just enough info and no more, lol. But elsewhere he does give radii for other curves. This tract map is spot on and exactly matching my real world measurements right on down to the hundredth of a foot. The county GIS is way off and pretty much useless by comparison.
