No person shall commence or perform any grading or filling or
clearing of hillside areas without first obtaining a grading permit
from the City Engineer.
All land within the boundaries of a development shall be graded
to drain and dispose of surface water without permanently ponding.
(§ 1, Ord. 601, eff. May 13, 1982)
A grading permit shall not be required if the project meets
any of the following conditions:
(a)
The
excavation does not exceed three feet in vertical depth at its deepest
point, measured from the original surface, and does not exceed 200
square feet in area;
(b)
The
fill does not exceed three feet in vertical height at its highest
point, measured from the natural ground surface, and does not cover
more than 200 square feet in area;
(c)
The
clearing of vegetation does not exceed 1,000 square feet in area;
or
(d)
The
use of land is for gardening primarily for home consumption.
(§ 1, Ord. 601, eff. May 13, 1982, as amended by § 4, Ord.
624, eff. August 9, 1984)
Applications for grading permits shall include:
(a)
A
proposed work plan and supporting documentation.
(1)
A proposed site work plan, with a reasonable scale not to exceed
a maximum scale of 500 feet to one inch, of the existing and finished
contour intervals not greater than five feet shown for all the area
to be cleared or prepared, plus a minimum of 100 feet in all directions
beyond the area to be cleared or prepared;
(2)
A physical land condition report, including the soil series and type,
designation of Soil Conservation Service Land Capability classification,
and geologic features, such as landslides and any other critical area
conditions, such as gullied areas, soil depth, erodibility, and capability
for establishing vegetation;
(3)
An evaluation of the subsurface information where the stability will
be lessened by the proposed grading or filling or where any of the
following conditions are discovered or proposed:
(i)
The locations where a fill slope is to be placed above a cut slope;
(ii)
The proposed cuts exceeding 10 feet in height, unless in competent
rock as determined by an engineering geologist;
(iii)
The locations of proposed fills exceeding 20 feet in height;
(iv)
The side hill fills to be placed on existing slopes steeper
than 16%;
(v)
The groundwater from either the grading project or adjoining properties
likely to reduce the stability;
(vi)
The zones of trapped water or high water table; or
(vii)
The areas where the topography is indicative of landslides,
as determined by an engineering geologist; and
(4)
Where any of the particular conditions set forth in subsection (3)
of this subsection is found, the subsurface investigations shall consist
of drilling, excavations, or observations of naturally exposed soil
and bedrock exposures at sufficient intervals and depths to indicate
the type of material or condition to be encountered at the final grading.
The person or firm making the investigation shall submit a written
report of its findings and recommendations;
(b)
A
grading plan containing the following information:
(1)
The elevations and dimensions, including the quantity, location,
and extent of the proposed grading;
(2)
Cross-section views through the property to be graded demonstrating
the relationship of the proposed cut and fill to the original surface;
and
(3)
Provisions for stockpiling topsoil and using it to top-dress exposed
areas to be revegetated or a statement that this provision is not
applicable;
(c)
A
tree and floral assessment containing the following information:
(d)
Assessment
of the site. The assessment of the site, based on the application
for a grading permit, shall determine the need for an erosion and
sediment control plan considering the detrimental effects of the construction
of the site as it pertains to:
