(Title and Section Amended by Ord. No. 171,175, Eff. 7/25/96.)
If at any stage of work on an excavation or fill the Department determines that further work as authorized by an existing permit is likely to endanger any property or public way, the Department may require as a condition to allow the work to continue that plans for such work be amended to include adequate safety precautions. Safety precautions may include, but shall not be limited to, specifying a flatter exposed slope or construction of additional drainage facilities, berms, terracing, compaction, cribbing, retaining walls or buttress fills, slough walls, desilting basins, check dams, benching wire mesh and guniting, rock fences revetments or diversion walls.
No person shall excavate or fill so as to cause falling rocks, soil or debris in any form to fall, roll, slide or flow onto adjoining properties.
91.7007.1. Restriction of Work During Rainy Season. (Amended by Ord. No. 172,592, Eff. 6/28/99, Oper. 7/1/99.) The period between October 1 and April 15 is hereby determined to be the period in which heavy rainfall normally occurs in the City of Los Angeles and is declared to be the “rainy season”. During this period no grading work in excess of 200 cubic yards (153 m3) shall be commenced on any single grading site under permit until an erosion control system has been approved and it has been demonstrated to the Department’s satisfaction that such grading work will not endanger life, limb, health, property or public welfare.
Whenever it appears that repair work to rectify substandard conditions and any grading project previously commenced pursuant to a permit issued by the Department will not be completed prior to the commencement of the rainy season, the Department may order and the permittee shall install temporary erosion control devices to protect the persons and property near such project. In addition, the Board of Public Works may direct the permittee to comply with the provisions of LAMC Section 61.02. (Amended by Ord. No. 185,587, Eff. 7/16/18.)
All hillside property owners or their agents shall submit erosion control plans to their district grading inspectors prior to October 1 for grading projects within unfinished grading work in excess of 200 cubic yards (153 m 3 ) and sites with substandard conditions, unless specifically exempted by the grading inspectors.
91.7007.2. Duration of Work. (Amended by Ord. No. 185,587, Eff. 7/16/18.) No person shall conduct any grading excavation or filling, including the export or import of earth material, between the hours of 6:00 p.m. and 7:00 a.m. on any day nor on Sunday at any time, except in emergencies as provided in LAMC Subsection 91.7005.4.
