No person shall do or cause any grading on property without first having obtained a permit to do so from the City Engineer if such grading will result in any of the following:
(b)
Any permanently unretained excavation or fill exceeding five cubic yards where the vertical distance between the top and bottom of the excavation or fill exceeds five feet at any location, disregarding benches; and the rate of slope of the surface exceeds two to one (2:1) for fill or one and one-half to one (1 1/2:1) for excavation, regardless of findings in the "Soils Report" called for in Section 7-12-275 herein.
(c)
Any excavation or fill exceeding five cubic yards within 15 horizontal feet of any property line if the bottom of such excavation is below a line descending at a rate of slope of two to one (2:1) from the existing ground surface at such property line, or if the top of such fill is above a line ascending at a rate of two to one (2:1) from such property line, regardless of the findings in the "Soils Report" called for in Section 7-12-275 herein.
(d)
Grading in connection with a building, swimming pool retaining wall or other structure where the vertical distance between top and bottom of the unretained slope will exceed five feet at any point, disregarding benches, when the cut slope exceeds one and one-half to one (1 1/2:1) or the fill slope exceeds two to one (2:1).
(e)
Any retained or unretained excavation or fill of any volume and height where the City Engineer has information or purported land stability problems on or in the vicinity of the site (i.e., "Land Stability Problem Area").
(f)
Any "land disturbance" as defined in Section 7-12-100, where the rate of slope of the ground surface exceeds 20%.
(g)
An excavation or fill which will encroach on or alter a natural drainage channel or watercourse.
(h)
The construction, reconstruction, alteration, repair, or installation of any structure in any natural watercourse.
(i)
Removal of the natural vegetation or groundcover from an area in excess of 5,000 square feet.
Grading of an emergency nature to safeguard life or property may be undertaken prior to the issuance of a grading permit. If the emergency work will result in any of the criteria set forth above, an application for grading permit shall be initiated with the City Engineer no later than 10 days after the commencement of the emergency and said application shall be diligently pursued by the applicant. |
A separate permit shall be required for each non-contiguous site. One permit may cover both an excavation and a fill on the same site. Property of a given ownership "divided" by a street, path, easement, is considered contiguous. |
