Embankment and cut areas shall not have slopes exceeding 33%. Sufficient fill and cut shall be provided behind curb and gutter in embankment areas to contain the curb and gutter and to provide for future sidewalks. Slopes and dimensions for these areas shall be in accordance with the street classification requirements. Erosion and sediment control and tree removal and conservation of vegetation requirements of this Article IV shall be adhered to.
