Based on the Plan information given in the sketch below;

Create a set of Level Notes by calculating the Elevations at the various Grid Points based on Grid Foresights shown.

Beginning Benchmark #$5$ value $=+{73\mathrm{.}60}^{\text{'}}$ USC&G Datum

The Backsight value $=+5\mathrm{.}25$ calculate the HI and the various Grid Elevations. Stationing should be labeled as A $1,$ A $2,$ etc.

If the Foresight Reading on Benchmark #$10=-3\mathrm{.}23,$ but the True Elevation Value of Benchmark #$10=75\mathrm{.}58$ what is the Vertical Error of Closure.

Use $5-1c$ Example of Differential Leveling Notes.
