We are planning some roads through some rough terrain. Through some advanced GIS data we are able to get fairly accurate elevation values at 100' intervals along the proposed roads.
Assume a purely vertical slope - by that I mean the path will be flat in the direction perpendicular to the way you are traveling and no side slopes to worry about.
The roads will be traveled by ATVs, UTVs, tractor, maybe a beat up farm truck, etc but are not main roads or anything that needs to travelled on by nice vehicles, trailers, etc.
What change in elevation over 100' becomes an issue? We don't want these roads to be the extreme offroad challenge every time we drive them but we also don't want to eliminate potential paths that are likely usable. I know there are many variables such as surface conditions but just generally speaking is what I am looking for. I was thinking stay under 30% grade or 30' change in 100' but not sure if that is right.
