J106.1 - Maximum cut slope.  


Latest version.
  • The slope of cut surfaces shall be no steeper than is safe for the intended use, and shall be not more than one unit vertical in two units horizontal (50 percent slope) unless the owner or the owner's authorized agent furnishes a geotechnical or an engineering geology report, or both, justifying a steeper slope. The reports must contain a statement by the Geotechnical Engineer or Engineering Geologist that the site was investigated and an opinion that a steeper slope will be stable and will not create a hazard to public or private property, in conformance with the requirements of Section 111. The Building Official may require the slope of the cut surfaces to be flatter in slope than 2 units horizontal to 1 unit vertical if the Building Official finds it necessary for the stability and safety of the slope.

    Exception:

    1.

    A cut surface shall be permitted to be at a slope of 1.5 units horizontal to one unit vertical (67 percent slope) provided that all of the following are met:

    1.1

    It is not intended to support structures or surcharges.

    1.2

    It is adequately protected against erosion.

    1.3
