that is if it is tangent to the preceeding course. Some say "along a tangent curve" but I think it is normally unnecessary to say so.
Thence with the arc of a tangent curve to the right having a radius of 160.00 feet and a central angle of 33 degrees 17 minutes 28 seconds, an arc distance of 92.97 feet to a point of tangency;
more or less.

said curve being subtended by a chord that bears n72d52'33"e with a length of 91.66 feet;
thence n89d31'17"e.....
thence northeasterly with a curve to the right, said curve having a radius of 160' , a distance of 92.97'.
Unless the curve is non-tangent I don't see the need for additional information.

I use all caps in my descriptions, they reproduce better.

Very much the same as Paden's

What, no delta angle?
At minimum we are required in Alabama to give radius, length, and delta angle. If it is non radial, then an angle to chord or to tangent must be added.

Note the Oxford Comma 😉
In New York, I do it as Dave Karoly, as that's how it is most often seen there.
In New Jersey, I do it as Paden Cash, but with the central angle, as that's how it's most often seen there.
I've always preferred the arc distance along an XXX radius curve to the left/right, chord bearing & distance. So simple even a CAD guy can draw it & a lawyer can understand it. All that tangent, delta's, etc can go on a curve table somewhere on the plat if need be.
Then 20 yrs later when somebody is trying to retrace your survey, what would they want to hold? Most likely the distance along the chord/arc and let the rest of the fluff kind of float to match possession. Start intersecting tangent lines, with record bearings, and all holy heck gets woke up.

Since only 2 of the variables are necessary to calcuate a tangent curve, I have heard the arguement that providing a 3rd component only adds potential for conflict.
I often only use the delta and curve length. I feel they depict the actual field positions except for very short radii curves. In those cases the delta and radius may be more reflective of field location and strength of figure.
You have the tangents coming and going, isn't that enough?
Jud, yours is the most similar to mine so far but since we're both Oregonians I suppose that's not surprising.
If I were going to go with only 2 I think I'd make radius one of them. That is the parameter you usually want held.
Oklahoma minimum standards require direction, L, R, D, CH bearing and distance. Oregon requires all that on plats but has no standard for legals. Most folks follow the plat requirement in their legals.
It just makes it easier to calculate and stake with a delta angle. Plus, it's in our regs.
