construction of a nuclear plant
Before it was excavated, the site’s elevation was approximately 35 m, and the elevation at the top of the cliffs was approximately 30 m. Since TEPCO selected grade levels of 10 m for the block of Units 1 to 4 and 13 m for the Unit 5 and 6 block, significant excavation was required, as shown in Fig. 1.2–6. The reasons for selecting grade levels of 10 m and 13 m are described in the section on ‘Geology’ below and are further discussed in Technical Volume 2, Section 2.1.
Units refer to nuclear units

Problems due to poor definitions of "grade level"
It appears that US definitions of grade level are not standardised in the same way as in the UK, which sets a datum point on site relative to ASL and all levels e.g. finished ground and floor levels and roof heights are measured from that datum point. The US method of measurement cited below ran into problems of developers cheating by earth-moving and had to be redefined according to this document.
'The Louisville Municipal Code (LMC) prescribes a maximum building height in all zone districts in the City. Section 17.08.045 of the LMC defines height as “the vertical distance measured from grade to the highest point on the roof surface.” Grade is defined in Section 17.08.205 of the LMC as “the average of the finished grade surface
elevation measured at the highest and lowest exterior corners of a structure.”'
