The slope distance and zenith angle observed from point $x$ to point $Y$ were $1501\mathrm{.}85$ ft $.$ and $86{27}^{\text{'}}{15}^{\text{'}\text{'}}.$ The instrument and rod target heights were equal. If the elevation of point $x$ is $102\mathrm{.}09$ ft $.$ above datum, what is the elevation of point $Y?($Hint: Don't forget to account for curvature and refraction.$)$
