DTM $\backslash$#$1$: For the figure below, the rectangle in the middle is a building pad at an elevation of $796.$ It is $\backslash (150^\{\backslash$prime$\}\backslash$times $100^\{\backslash$prime$\}\backslash ).$ Assuming a cut slope and a fill slope of $\backslash (4$: $1\backslash ),$ identify catchpoints with small $+$ signs at the intersection of the limit of excavation and corresponding contour lines. Connect the catchpoints with a daylight line. Recall that a daylight line is delineates the limit of excavation.
