It is unlawful for any person to make, or cause or permit to be made, any excavation, fill or drain in, under or on the surface of any land, public or private, in the City, without first obtaining a permit, or in violation of any of the terms or conditions of such permit; provided, however, that no permit shall be required for excavations for the foundation or basement of any building for a building permit has been issued, or for grading in subdivisions according to plans which have been approved by the City Council as required by SMC Title 9, Subdivisions, or for excavations by any public utility for the installation, operation, inspection, repair or replacement of any of its facilities (with the exception of power-driven or power-operated excavating or boring equipment that will be used within 10 feet laterally of any "high priority subsurface installation" as defined in California Government Code Section 4216(e), or for the grading of any parcel of land where no bank is left standing more than four feet in height and/or wherein less than 50 cubic yards of earth are removed, placed and/or otherwise disturbed in any 12 consecutive months; provided further, however, that a permit is required for work of any magnitude where watercourses are altered.
Recognizing the significant threat to public health, property and the environment that arises when visual confirmation of the precise depth and lateral extent of certain hazardous underground utilities cannot be established by surface locating methods, a permit shall be required of any entity desiring to install, inspect, repair or replace any underground utility, appurtenance or facility by power-driven or power-operated excavating or boring equipment that is within 10 feet laterally of any "high priority subsurface installation" as defined in California Government Code Section 4216(e). Further, in conformance with California Government Code Section 4216.4, the permittee shall determine the exact location of said high priority subsurface installations in conflict with the excavation by excavating with hand tools within the area of the approximate location of the high priority subsurface installations in the presence of a City inspector, who shall be required to approve in writing the use of any power-operated or power-driven excavating or boring equipment within the approximate location of the high priority subsurface installation. As provided for in California Government Code Section 4216.4, power-operated or power-driven excavating or boring equipment may be used for the removal of any existing pavement if there are no high priority subsurface installations contained in the pavement. If documented notice of the intent to use vacuum excavation devices, or power-operated or power-driven excavating or boring equipment, has been provided to the high priority subsurface installation operator or operators and it is mutually agreeable with the operator or operators and the excavator, the excavator may utilize vacuum excavation devices, or power-operated or power-driven excavating or boring equipment, within the approximate location of a subsurface installation and to any depth. In such a case, the City Inspector's approval shall be made in writing along with the written agreement between permittee and high priority subsurface installation operator(s). In addition, the permittee is required to comply with the operator's requests to protect the subsurface installation as specified by the operator prior to start of excavation as defined in California Government Code Sections 4216.2(a)(2) and 4216.7(a).
