R= vs L= Quick Question
I am a landowner and don't have any experience reading a survey plan. Could some one tell me what the actual frontage along the road is in regards to the attached small portion of our plan? Is it L=167.25' or R=220.00' ? I assume it's 167.25" but I would greatly appreciate knowing for sure.

L=length along the curve.
The triangle=delta=the included angle of the arc.

Perhaps the most important thing for the owner to realize is that the frontage distance of 167.25' is measured along the arc. If he stretches a tape from one front corner toward the other and measures the frontage distance, he's going to overshoot the other corner. The chord (straight-line) distance is only 163.25'.

You guys jumped in very well on this. Hope the original poster understands now. The comment on the small difference, in this case, between the arc length and a straight-lined measurement is very important. For a very different radius the difference can be very important. For example, on a radius of 50 feet with a straight distance of 100 feet between the ends the arc length could be as much as 157 feet.
