1.3. It is no more than 8 feet (2438 mm) in height. <br />1.4. It is approved by the building official. <br />2. A cut surface in bedrock shall be permitted to be at a <br />slope of 1 horizontal to 1 vertical (100 percent). <br />SECTION J107 <br />FILLS <br />J107.1 General. Unless otherwise recommended in the soils <br />report, fills shall conform to provisions of this section. <br />J107.2 Surface preparation. The ground surface shall be pre- <br />pared to receive fill by removing vegetation, topsoil and other <br />unsuitable materials, and scarifying the ground to provide a <br />bond with the fill material. <br />J107.3 Benching. Where existing grade is at a slope steeper than <br />5 horizontal to 1 vertical (20 percent) and the depth of the fill <br />exceeds 5 feet (1524 mm) benching shall be provided in accor- <br />dance with Figure J107.3. A key shall be provided which is at <br />least 10 feet (3048 mm) in width and 2 feet (610 mm) in depth. <br />J107.4 Fill material. Fill material shall not include organic, <br />frozen or other deleterious materials. No rock or similar irre- <br />ducible material greater than 12 inches (305 mm) in any dimen- <br />sion shall be included in fills. <br />J107.5 Compaction. All fill material shall be compacted to 90 <br />percent of maximum density as determined by ASTM D 1557, <br />Modified Proctor, in lifts not exceeding 12 inches (305 mm) in <br />depth. <br />J107.6 Maximum slope. The slope of fill surfaces shall be no <br />steeper than is safe for the intended use. Fill slopes steeper than <br />2 horizontal to 1 vertical (50 percent) shall be justified by soils <br />reports or engineering data. <br />For SI: 1 foot = 304.8 mm. <br />..Ilita 1.-11... <br />14/5 but 211.

Cut and fill slopes shall be set back from the <br />property lines in accordance with this section. Setback dimen- <br />sions shall be measured perpendicular to the property line and <br />shall be as shown in Figure J108.1, unless substantiating data is <br />submitted justifying reduced setbacks. <br />J108.2 Top of slope. The setback at the top of a cut slope shall <br />not be less than that shown in Figure J108.1, or than is required <br />to accommodate any required interceptor drains, whichever is <br />greater. <br />J108.3 Slope protection. Where required to protect adjacent <br />properties at the toe of a slope from adverse effects of the grad- <br />ing, additional protection, approved by the building official, <br />shall be included. Such protection may include but shall not be <br />limited to: <br />1. Setbacks greater than those required by Figure J108.1. <br />2. Provisions for retaining walls or similar construction. <br />3. Erosion protection of the fill slopes. <br />4. Provision for the control of surface waters. <br />SECTION J109 <br />DRAINAGE AND TERRACING <br />J109.1 General.
