To what elevation value are the tops of blue top stakes equal?

Blue top stakes are used to communicate the finish elevation—the planned final height of the surface at that spot. When grading a site, crews use these stakes to know exactly how high the ground should be once work is complete, guiding cuts and fills to match the design. This finish elevation is distinct from the current ground elevation (the soil as it sits now) and from instrument elevation (the height of the surveying instrument above a reference). So the tops of blue top stakes tell you the target finished height, not the existing ground or the measurement setup.
