The levee is to be built along the side of a river to protect a nearby town from flooding. Geotechnical engineer considering the potential for a landslide along the failure surface. If the natural soils below the levee are saturated clay and the shear strength parameters at Point \( \mathrm{A} \) are undrained shear strength \( =700 \mathrm{psf}, \mathrm{c}^{\prime}=300 \mathrm{psf} \), and \( \phi^{\prime}=24^{\circ} \). The shear stress at point \( \mathrm{A} \) is \( 400 \mathrm{lb} / \mathrm{ft}^{2} \), compute the FoS against sliding at Point A.
