A. General. All grading operations for which a permit is required shall
be subject to inspection by the Director. When required by the Director, special
inspection of grading operations and special testing shall be performed in
accordance with the provisions of Section 24.70.120 C.
B. Grading designation. All grading in excess of 5,000 cubic yards
shall be performed in accordance with the approved grading plan prepared by a
civil engineer and shall be designated as "engineered grading." Grading
involving less than 5,000 cubic yards may also be designated as "engineered
grading" by the Director if the grading will
1. support a building or structure of a permanent nature;
2. support other engineering works such as, but not limited to, tanks,
towers, machinery, retaining wall, and paving;
3. be deemed a potential hazard under Section 24.70.030. The permittee
with the approval of the Director may also choose to have the grading
performed as "engineered grading." Otherwise, the grading shall be designated
as "regular grading."
C. Engineered grading requirements. For engineered grading, it shall
be the responsibility of the civil engineer who prepares the approved grading
plan to incorporate all recommendations from the soil engineering and
engineering geology reports into the grading plan. He shall also be responsible
for the professional inspection and approval of the grading within his area of
technical specialty. This responsibility shall include, but need not be limited
to, inspection and approval as to the establishment of line, grade, and drainage
of the development area. The civil engineer shall act as the coordinating agent
in the event that need arises for liaison between the other professionals, the
contractor, and the Director. The civil engineer shall also be responsible for
the preparation of revised plans and the submission of as-graded grading plans
upon completion of the work. The grading contractor shall submit in a form
prescribed by the Director a statement of compliance to said as-graded plan.
Soil engineering and engineering geology reports shall be required as
specified in Section 24.70.050. During grading all necessary reports, compaction
data, and soil engineering and engineering geology recommendations shall be
submitted to the civil engineer and the Director by the soil engineer and the
engineering geologist. The soil engineer’s area of responsibility shall include,
but need not be limited to, the professional inspection and approval concerning
the preparation of ground to receive fills, testing for required compaction,
stability of all finish slopes, and the design of buttress fills, where
required, incorporating data supplied by the engineering geologist.
The engineering geologist’s area of responsibility shall include, but need
not be limited to, professional inspection and approval of the adequacy of
natural ground for receiving fills and the stability of cut slopes with respect
to geological matters, and the need for subdrains or other ground water drainage
devices. He shall report his findings to the soil engineer and the civil
engineer for engineering analysis.
The Director shall inspect the project at the various stages of work
requiring approval and at more frequent intervals necessary to determine that
adequate control is being exercised by the professional consultants.
D. Regular grading requirements. The Director may require inspection and
testing by an approved testing agency. The testing agency’s responsibility shall
include, but need not be limited to, approval concerning the inspection of
cleared areas and benches to receive fill, and the compaction of fills. When the
Director has cause to believe that geological factors may be involved the
grading operation will be required to conform to "engineered grading"
E. Notification of noncompliance. If, in the course of fulfilling their
responsibility under this Chapter, the civil engineer, the soil engineer, the
engineering geologist, or the testing agency finds that the work is not being
done in conformity with this Chapter or the approved grading plans, the
discrepancies shall be reported immediately in writing to the person in charge
of the grading work and to the Director. Recommendations for corrective
measures, if necessary, shall be submitted.
F. Transfer of responsibility for approval. If the civil engineer, the
soil engineer, the engineering geologist, or the testing agency of record are
changed during the course of the work, the work shall be stopped until the
replacement has agreed to accept the responsibility within the area of their
technical competence for approval upon completion of the work.
