A city-issued Grading Permit is required before the commencement of any of the following filling or grading activities (per City Code 15.48.030):
Grading activities in excess of ten cubic yards of earth
Grading activities which may result in the diversion of existing drainage courses, both natural and man-made, from their natural point of entry or exit from the grading site
Grading and paving activities resulting in the creation of impervious surfaces greater than 2,000 square feet or more in area
Any excavation beyond the limits of a basement or footing excavation, having an unsupported soil height greater than 5 feet after the completion of such a structure
Grading activities involving the clearing or disturbance of one-half acres (21,780 square feet) or more of land
Those fill and grading activities proposed to be undertaken in conjunction with a land use application, including but not limited to subdivisions, planned unit developments, partitions and site plan reviews, do not require a separate grading permit. Approval of the construction plans submitted through the land use application process shall constitute the grading permit required under Chapter 15.48.
