This design template is to be placed at station $1+50\mathrm{.}00.$ the elevation of the existing ground at Station $1+50\mathrm{.}00$ is $5005\mathrm{.}89$ feet. The cut at centerline at station is $2\mathrm{.}4$ feet. Follow the template on the right side of centerline. The side slope of $1\mathrm{.}5$:$1$ finds the catchpoint at a slope distance of $11\mathrm{.}95$ feet from the bottom of the ditch. Compute horizontal distance of the catchpoint from centerline.
