The intersection below has the tollowing centerline elevations and azimuths.

BC CL Elev Sta. $0+444\mathrm{.}785.$

The remaining $2$ numbers of your BC CL Elev will be the first two

digits of your student number excluding leading zeros.

i$.$e Student number $0403682,$ BC CL Elev. $=222\mathrm{.}440m$

EC CL Elev $($Sta$.2+111\mathrm{.}555)=222\mathrm{.}1$dotsm.

The remaining $2$ numbers of your EC CL Elev will be the last two

digits of your student number.

i$.$e Student number $0403682,$ EC CL Elev. $=222\mathrm{.}182m$

Back tangent azimuth $=108$dots $\text{'}59$

The remaining $2$ numbers of your back tangent azimuth will be the

first two digits of your student number excluding leading zeros.

i$.$e Student number $0403682,$ back tangent azimuth. $=108{40}^{\text{'}}{59}^{\text{'}}$

a$.$ Calculate the proposed top of curb elevations for the BC$,$ EC and two

equal intermediate points along the face of curb radius.

b$.$ Calculate the required chord lengths for grade stakes placed at an offset

of $3m$ inside the face of curb radius.
