If at any stage of the work the City Engineer determines that further land development work as authorized is likely to endanger any public or private property or result in the deposition of debris on any public way or interfere with any existing drainage course, the City Engineer may require, as a condition to allowing the work to be continued, that such reasonable safety precautions be taken as he considers advisable to avoid such likelihood of danger. The permittee will be responsible for removing any silt and debris deposited upon adjacent and downstream public or private property resulting from his grading operations. Silt and debris shall be removed, and damage to adjacent and downstream property repaired, as directed by the City Engineer. Erosion and siltation control may require temporary or permanent siltation basins, energy dissipaters, or other measures as field conditions warrant, whether or not such measures are a part of approved plans. (Ord. 3005 § 1, 2005; Ord. 1877 § 2, 1979; Ord. 1797 § 1, 1978).
