prevent the use of alternate materials, methods or means of conforming to such
standards, provided such alternate has been approved.
The Building Official shall approve such an alternate provided he or she finds
that the alternate is, for the purpose intended, at least the equivalent of that
prescribed in this Code in quality, strength, effectiveness, durability and safety.
The Building Official shall require that sufficient evidence or proof be submitted

floodways have not been designated, unless it has been demonstrated through
hydrologic and hydraulic analyses performed in accordance with standard
engineering practice that the proposed work will not result in any increase in the
level of the base flood.
J101.3 General. 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
Page 11 of 47 Pages
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.
J101.4 Safety Precautions. If at any stage of the work the Building Official
determines that previously approved grading is likely to endanger any public or
private property or result in the deposition of debris on any public way or
interfere with any existing drainage course, the Building Official may order the
work stopped by notice in writing served on any persons engaged in doing or
causing such work to be done, and any such person shall forthwith stop such
work. The Building Official may authorize the work to proceed if the Building
Official finds adequate safety precautions can be taken or corrective measures
incorporated in the work to avoid the likelihood of such danger, deposition or
interference. If the grading work as done has created or resulted in a hazardous
condition, the Building Official shall give written notice requiring correction.

result. Special precautions approved by the Building Official shall be made to
prevent imported or exported materials from being deposited on the adjacent
public way and/or drainage courses.

and maintain all precautionary measures necessary to protect adjacent water
courses and public or private property from damage by erosion, flooding, and
deposition of mud, debris, and construction-related pollutants originating from
the site during grading and related construction activities.
J101.8 Maintenance of Protective Devices and Rodent Control. The owner
of any property on which grading has been performed pursuant to a permit
issued under the provisions of this Code, or any other person or agent in control
of such property, shall maintain in good condition and repair all drainage
structures and other protective devices and burrowing rodent control, when
they are shown on the grading plans filed with the application for grading
permit and approved as a condition precedent to the issuance of such permit.

conveniently accessible locations where a hose no longer than 50 feet (15,240
mm) is necessary for irrigation.
The requirements for permanent irrigation systems may be modified upon
specific recommendation of a landscape architect or equivalent authority that,
because of the type of plants selected, the planting methods used and the soil
and climatic conditions at the site and irrigation will not be necessary for the
maintenance of the slope planting.

Where unusual conditions or special hazards exist, the Building Official
may require security for grading involving less than 1,000 cubic yards (764.6 m3).
Security required by this Section may include incidental off-site grading on
property contiguous with the site to be developed, provided written consent of
the owner of such contiguous property is filed with the Building Official.
The Building official may waive the requirements for a security for:

Sections J 113.2 and J 113.3 or submit the wet weather erosion control plans
required by Section J1 13 by the dates specified therein, it shall be deemed that
a default has occurred under the conditions of the grading permit security.
Thereupon, the Building Official may enter the property for the purpose of
installing, by City forces or by other means, the drainage, erosion control and
other devices shown on the approved plans, or if there are no approved plans,
as the Building Official may deem necessary to protect adjoining property from
the effects of erosion, flooding, or the deposition of mud, debris or constructed .
