24-8009 Page 13 Compaction Prior to fill placement, the exposed surface should be scarified to a minimum depth of six (6) inches, fill placed in six (6) inch loose lifts, moisture conditioned to optimum moisture content, and compacted to a minimum relative compaction of ninety (90) percent in accordance with ASTM D 1557. Trenching All excavations should conform to CAL-OSHA and local safety codes. Drainage Positive site drainage should be maintained at all times. Water should be directed away from foundations and not allowed to pond and/or seep into the ground. Pad drainage should be directed toward the street/parking or other approved area. Roof gutters and down spouts should be utilized to control roof drainage. Down spouts should outlet a minimum of 5 feet from the proposed structure or into an approved subsurface drainage system. We would recommend that any proposed open-bottom planters adjacent to proposed structures be eliminated for a minimum distance of 10 feet. As an alternative, closed-bottom type planters could be utilized. An outlet placed in the bottom of the planter could be installed to direct drainage away from structures or any exterior concrete flatwork. All site drainage shall comply with the 2022 California Building Code. Utility Trench Backfill All utility trench backfill in structural areas and beneath hardscape features should be brought to optimum moisture content and compacted to a minimum relative compaction of 90 percent of the laboratory standard. Flooding/jetting is not recommended. Sand backfill, (unless trench excavation material), should not be allowed in parallel exterior trenches adjacent to and within an area extending below a 1:1 plane projected from the outside bottom edge of the footing. All trench excavations should minimally conform to CAL-OSHA and local safety codes. Soil generated from utility trench excavations may be used provided it is moisture conditioned to optimum moisture content and compacted to 90 percent minimum relative compaction. Temporary Excavation Recommendations In areas not adjacent to existing structures or property lines, soils may be cut vertically to a depth of approximately four (4) feet below adjacent grade. Excavations deeper than 4 feet should be temporarily shored or sloped back to at least 1H:1V or flatter for the entire excavation. The exposed slope face should be kept moist (but not saturated) during construction to reduce local sloughing. No surcharge loads should be permitted within a horizontal distance equal to the height of cut from the toe of excavation unless the cut is properly shored. Temporary excavation that extends below an imaginary plane inclined at 45 degrees from the property line or below the edge of adjacent existing footings will require shoring. Temporary Shoring Temporary shoring may be required for those excavations where temporary slope cuts as specified above are not feasible. Temporary cantilever shoring should be designed to resist an active earth pressure of 35 pounds per cubic foot equivalent fluid pressure for level conditions behind shoring. The design of shoring should also include surcharge-loading effects of existing 2039 N Victoria Drive #24/28/2025
