[quote]QUOTE: Originally posted by HAZMAT9 .. Hey Gary how did you figure out the width I needed in terms of easement.....what do I need if I decide to go to 40" radius? Steve [/quote] Not exactly. There is a bit of geometry involved depending the equipment length. A easment isn't really needed for curves over 30" radius. However any curve will look better by adding easments. Is your reverse curve more than 180 degrees? If so, easments will not add much, if any, width of the layout. Adelie figured an offset of 3/4" for a 40"radius. So then, an 80" diameter curve, plus easments and some space from the edge for saftey, I'd say 7 1/2 feet of space would be a safe minimum. Not what you like to hear, is it? But then you don't really need easments with such a wide curve. That you would be at your 7 foot limit. However, you should add a guard rail at the edge.
