Throughout the growing season the Bluegrass rough moves laterally and can quickly grow over valve boxes that are ten inches in diameter. This would become problematic if the box became completely grown over and we were unable to quickly locate it in the case of an emergency. Generally we will only have to edge around the boxes once a season to them them easily identifiable.
If we were to ever lose track of a critical component we could always refer back to the GPS coordinates to find the item, but that would be the last choice in the case of an emergency.
