Date: Mitigation Measure 4.4-6b: Following clearing and are properly stripping,all areas to receive fill, slabs-on-grade,or implemented. pavement should be scarified to a depth of at least 12 inches, moisture conditioned,and compacted to the requirements for engineered fill. Mitigation Measure 4.4-6c: Site soils and bedrock used for engineered fill shall have organic content of less than 3 percent. Rocks greater than 6-inches in size shall not be placed at depths greater than 10 feet from finished grade. Rocks greater than 18 inches in size should be broken down such that their maximum dimension is less than 12 to 18-inches,or placed in non-structural fills below slopes or under one of the proposed detention basins.Alternatively,these rocks could be used in landscaping and/or creek restoration projects. Mitigation Measure 4.4-6d: Engineered fills shall be compacted to the specifications stated in the geotechnical framework. Over compaction of expansive materials(with a plasticity index of greater than 12) should be avoided within the upper five feet of building areas.All fills shall be placed in lifts not exceeding 12 inches,or the depth of penetration of the compaction equipment used,whichever is less.
