Completely design the cantilever retaining wall shown. The height of wall hw is 22 ft, the backfill is level, the surcharge is 600 psf, we = 100 lb/ft3, h′ = 4 ft, Ka = 0.30, and the allowable soil pressure is 4 ksf. Use a coefficient of friction of concrete on soil of 0.5, f′ c = 3000 psi, and fy = 60,000 psi. The required factor of safety against overturning is 2.0 and against sliding is 1.5. The wall batter should be between
 and
 in./ft. The design is to be in accordance with the ACI Code (318-08).
