$**$I want a different solution method $**$

Exampe $(5)$

$A=2\mathrm{.}28$

$L=600$

PVC Sta. $=(110+00)-300=(107+00)$

$-x_{\text{p}\text{i}\text{p}\text{e}}=(110+85)-(107+00)={385}^{\text{'}}$

Very clear from the sKetch

$-$Elw. of the $PVC=1098\mathrm{.}4-1\mathrm{.}2****$ sta $=1094\mathrm{.}8ft$

Elew. of the intial tangent $=1094\mathrm{.}8+3\mathrm{.}85$ sta. $**1\mathrm{.}2={1099\mathrm{.}42}^2$

Dekermine the offset above the pipe at $x=385ft$

$Y=\frac{A}{200(L)}{x}^2=\frac{|1\mathrm{.}2-(-1\mathrm{.}08)|}{200(600)}(385{)}^2=2\mathrm{.}82ft$

Elev. of the Curve above the pipe $=1099\mathrm{.}42-2\mathrm{.}82=1096,6ft$

Elow. of the top of the pipe $=1091\mathrm{.}6+\frac{4}{2}=1093\mathrm{.}60ft$

The pipe is $(1096\mathrm{.}6-1093\mathrm{.}6)=3ft$ under the carve.

Highest Point: $K=\frac{600}{2\mathrm{.}28}=263\mathrm{.}16$

$x=K|G_1|=263\mathrm{.}16**|1\mathrm{.}2|=315\mathrm{.}79ft$

Sta. of the highest point $=(107+00)+315\mathrm{.}79=(110+15\mathrm{.}74)$
