No land shall be graded, cut, or filled so as to create a slope exceeding a vertical rise of one (1) foot for each three (3) feet of horizontal distance between abutting lots, unless a wall of sufficient height and thickness is provided to retain the graded bank. Major cuts, excavation, grading, and filling, where the same materially changes the site and its relationship with the surrounding areas or materially affects such areas, shall not be permitted if such excavation, grading, and filling will result in a slope exceeding a vertical rise of one (1) foot for each three (3) feet of horizontal distance between abutting lots or between adjoining tracts of land, except where adequate provision is made to prevent slides and erosion by cribbing and retaining walls.
