17.12.010 - Applicability.
No person shall do any grading upon any lot, parcel or tract of land without first having obtained a grading permit from the Public Works Director in compliance with all the provisions of this title except that a grading permit shall not be required for any of the following:
A. An excavation below finished grade for the basements and footings of a building, a retaining wall, a pool, or other structure authorized by a valid building permit. This provision shall not exempt any fill made with the material from such excavation nor exempt any excavation having an unsupported height greater than five feet after the completion of such structure.
B. Cemetery graves.
C. Refuse disposal sites controlled by other regulations.
D. Excavations and embankments performed by a public utility, governmental agency, or private developer for the construction of roadways, pipelines or utility lines within rights-of-ways or easements. Any work done in a public right-of-way dedicated to the City shall be regulated by the Public Works Director.
E. Mining, quarrying, excavating, processing, stockpiling of rock, sand, gravel, aggregate or clay where established and operating under the applicable provisions of this chapter, provided such operations do not affect the lateral support or increase the stresses in or pressure upon any adjacent or contiguous property as verified by a civil engineer's report.
F. Exploratory excavations under the direction of soils engineers or engineering geologists.
G. An excavation which:
1. Is less that two feet in depth; or
2. Does not create a cut slope greater than five feet in height and steeper than two horizontal to one vertical.

A fill less than three feet in depth and placed on natural terrain with a slope flatter than five horizontal to one vertical, not intended to support structures, which does not exceed 50 cubic yards on any one lot, including spoil from foundation excavation, and does not obstruct a drainage course. Lot drainage on the subject lot shall be directed away from any structure. Adjacent parcels which are to be graded at the same time will be considered as one and exceedance of the 50 cubic yards will be calculated as the sum of the two parcels.
I. Emergency work as authorized by the City necessary to protect life, limb or property or to maintain the safety, use or stability of a public right-of-way or drainage course.
J. Common agricultural practices on agriculturally zoned or agriculturally designated lands.
K. Grading in an isolated, self-contained area if there is no danger apparent to private or public property, the site is not within a drainage area or arroyo, it does not contain slopes exceeding ten percent and it is not visible from the public right-of-way.
L. Lots or projects having less than one acre in total area and which meet the conditions of Sections 17.12.010.G. 1. and 17.12.010.H. and certification is provided by the engineer subject to the approval of the Public Works Department.
