Department of Forestry Gradation Specs

[durtaholic]

Hello,

Can anyone point me in the direction of gradation specifications for Grading " D " for the Department of Forestry ? I found limits pertaining to trails but wondered if there was anything else for forest roads and such .

Thanks for the help !

Jurisdiction?

Sorry for the slow delay . It is in the state of Oregon. We found something that reference the National Department of Transportation. The contractor was pretty vague to start with .

Thanks ...
