In addition,the lou are graded to slope away from the tops of slopes and all slopes have been covered with jute ms.tiog and hydroseeded for erosion protection. In ou: opinion, where slopes Lava been placed, compaaed, graded, and vegetated as described above, the minimum building setback distance can be reduced to 10 feet. The setback distance is the horizontal distance meacured from the front face of the footing to the face of the slope. It should be understood that if the setback distance is reduced to 10 feet, the risks of losin� access, reducing the design life of the foundations and having slope movement impact the house foundations aze increaced. .. . . ..� , � _..... .,..
