To make it easier for the equipment operators, grade stakes are marked to the nearest which interval?

Grade stakes are read by equipment operators from a distance, so the markings need to be easy to read quickly while still giving useful guidance for grade control. Marking to the nearest half foot or whole foot provides a practical balance: it offers enough accuracy to stay on the designed grade without requiring the operator to interpret small, hard-to-read numbers. Using finer intervals like tenths of a foot or metric units would be harder to read and more prone to misreading in field conditions, while a quarter-foot would add unnecessary precision for day-to-day operation. So the standard is to mark stakes to the nearest half foot or full foot.
