The city adopts the erosion control provisions imposed by the
NPDES permit, including the following:
(a) The project site shall be prepared and maintained to control against
erosion in accordance with this chapter. Where cut slopes are not
subject to erosion due to the erosion-resistant character of the materials,
such protection may be omitted upon approval by the building official
and/or director of public works.
(b) Where necessary, temporary, and/or permanent erosion control devices
such as desilting basins, check dams, riprap, or other devices, as
approved by the building official and/or director of public works,
shall be employed to control erosion and provide safety.
(c) Paved streets, sidewalks, and other improvements shall be maintained
in a neat and clean condition free of loose soil, construction debris,
and trash. Street sweeping using a vacuum sweeper or other equally
effective means shall be used on a regular basis to prevent storm
flows from carrying sediment and debris outside the project boundaries.
(d) Unless otherwise approved by the building official and/or director
of public works, the owner shall be required to retain a civil engineer
who will be responsible for the design of all erosion control improvements
and initial approval of the installation of permanent and semi-permanent
erosion control devices during each rainy season until the work authorized
by the permit is given final approval. The owner shall retain the
civil engineer to periodically review the field condition and modify,
as needed, the design of the permanent and semi-permanent erosion
control devices during the rainy season. Installation and maintenance
of all erosion control devices shall be the responsibility of the
owner.
(e) Desilting facilities shall be provided at drainage outlets from the
graded site where necessary.
(f) Desilting basins constructed of compacted earth shall be compacted
to a relative compaction of ninety percent of maximum density. A soil
engineering report, prepared by the soil engineer, which includes
the type of field-testing performed, location, and results of testing
shall be submitted to the building official and/or director of public
works for approval upon completion of the desilting basins.
(g) Equipment and workers for emergency work shall be made available
at all times. Necessary materials shall be available on-site and stockpiled
at convenient locations to facilitate rapid construction of temporary
devices when rain is imminent.
(h) Erosion protection shall consist of effective planting of all slopes
in excess of five feet high unless otherwise approved by the building
official and/or director of public works. Protection for the slopes
shall be installed as soon as practicable which may be prior to rough
grade approval. Effective planting shall be installed, fully germinated,
and effectively cover the required slopes prior to final approval
unless otherwise approved by the building official and/or director
of public works.
(i) The erosion-control provisions shall take into account drainage patterns
during the current and future phases of grading.
(j) All removable protective devices shown shall be in place at the end
of each working day when the five-day rain probability forecast exceeds
forty percent.
(k) Graded areas around the tract perimeter must drain away from the
face of slopes at the conclusion of each working day.
(l) Any violation of an applicable federal or state-issued stormwater permit, or failure to conform to the city's water quality ordinance, including, but not limited to, the stormwater regulations set forth in Chapter
14.40 of this code, or failure to comply with stormwater related provisions of a grading permit or of a grading plan prepared to secure such a permit, is a violation of this chapter.

is performed for regular grading, as applicable.
(a) An as-built grading plan prepared by the civil engineer showing original
ground surface elevations, as-graded ground surface elevations, lot
drainage patterns, and the locations and elevations of surface drainage
facilities and of the outlets of subsurface drains. As-constructed
locations elevations and details of subsurface drains shall be shown
as reported by the soils engineer. Civil engineers shall state that
to the best of their knowledge the work within their area of responsibility
was done in substantial conformance with the final approved grading
plan.

services, including locations and elevations of field density tests,
summaries of field and laboratory tests, other substantiating data,
and comments on any changes made during grading and their effect on

report. Soils engineers shall submit a statement that to the best
of their knowledge, the work within their area of responsibilities
is in accordance with the approved soils engineering report and applicable
provisions of this chapter.
(c) A report prepared by the engineering geologist retained to provide
such services including a final description of the geology of the
site and any new information disclosed during the grading and the
effect of same on recommendations incorporated in the approved grading
plan. Engineering geologists shall submit a statement that, to the
best of their knowledge, the work within their area of responsibility
is in accordance with the approved engineering geologist report and
applicable provisions of this chapter.
(d) The grading contractor shall submit in a form prescribed by the building
official a statement of conformance to said as-built plan and specifications.
(Ord. 1593 § 2, 2022)
The permittee shall notify the building official when the grading
operation is ready for final inspection. Final approval shall not
be given until all work including installation of all drainage facilities
and their protective devices and all erosion-control measures have
been completed in accordance with the final approved grading plan,
and the required reports have been submitted.
(Ord. 1593 § 2, 2022)
Whenever the building official determines that any existing
excavation or embankment or fill on private property has become a
hazard to life and limb, or endangers property, or adversely affects
the safety, use, or stability of a public way or drainage channel,
the owner of the property upon which the excavation or fill is located,
or other person or agent in control of said property, upon receipt
of notice in writing from the building official, shall within the
period specified therein repair or eliminate such excavation or embankment
to eliminate the hazard and to be in conformance with the requirements
of this code.

the request of the director of public works, the enforcing attorney
may seek a court order to enjoin and/or abate the nuisance.
(Ord. 1593 § 2, 2022)
Any person who negligently or knowingly violates any provision
of this chapter, undertakes to conceal any violation of this chapter,
continues any violation of this chapter after notice thereof, or violates
the terms, conditions, and requirements of any permit issued pursuant
to this chapter, shall be guilty of a misdemeanor punishable by a
