A geologic permit shall be obtained for any development within the affected areas. For subsequent building permits, such as for decks or room additions, the original geologic permit is acceptable, if it is no older than five years and the report author evaluates the new building permit plans and sends a letter to the city that bears the stamp of the licensed geologist or engineering geologist, acknowledging that the submitted plans have been reviewed and that such building activity can be safely accomplished. In areas having slopes greater than 20%, a geologic permit shall also be obtained before removing vegetation from or grading an area in excess of 20,000 square feet or adding or removing 90 cubic yards of earth in an area of 5,000 square feet. Minimal accessory uses that do not require a building permit (playground equipment, small gazebo, and the like) are excluded from the requirements of this subchapter.
