Traverse curve with only angle and arc

[SenecaFrancis]

I have a centerline description that only gives the angle and arc distance. From the searching this forum it looks like I have to have a radius. Does anyone know a work around? 

The legal is from 1923 so it is definitely not perfect.

Hi Seneca

Could you try using the Circular Arc tool to calculate curve parameters? - use your existing, known parameters to create the circular arc and then once the arc is created, change the Delta parameter to Radius to obtain the radius of the arc.

That mostly worked. Thank you!

You should talk to any surveyors you know. This is a common problem for them to solve. I was provided the attached by some surveyors.
