The road is being design for internal transportation in the factory.
Please see below the section for the internal road in the factory, i have given 1% slope towards the boundary.

Is 1% slope enough considering the width of the road is 53' or should i increase the slope to 2.5%?
Also what should be depth of the storm water channel & drainage pipe passing parallel to the road near the boundary. I have suggested 8" from the Finish Road level. Is it enough or should i for more depth?
Please check and let me know, also i am unable to find design guidelines for road any help on the same will be highly appreciated.
