Working on a maintenance program for my local southwest airport, can you tell me what FAA document specifically states that the FAA recommends grass or turf height to be 5 to 8 inches?

Have a look at this Advisory Circular. There are numerous recommendations involving vegetation, but I couldn't find specific heights for grass mentioned. It DOES recommend lower growing turf, and discing or plowing taller grasses (milo, ryegrass) before they can seed out.
