All grading and excavating shall be in compliance with the regulations established in Chapter
20.40.
(Ord. 88-O-117 § 1, 1988)
(a) A preliminary soil report, based upon adequate test borings or excavations
of every subdivision as defined in this chapter shall be prepared
by a civil engineer registered in the state.
(b) When a report as required by this section has been prepared, such
fact shall be noted on the final subdivision map together with the
date of the report and the name of the engineer making the report.
The preliminary report shall be filed with the building division.
(c) If the preliminary soil report indicates the presence of expansive
soils, or other soil conditions which, if not corrected, would lead
to structural defects, a soil investigation of each lot in the subdivision
shall be prepared by a civil engineer registered in the state. Such
soil investigation report shall recommend corrective action which
is likely to prevent structural damage to each structure proposed
to be constructed on such soil and the report shall be filed with
the building division.
(d) The chief building official shall approve the soil investigation
and, if the chief building official determines that the recommended
action is likely to prevent structural damage to each structure constructed
on each lot in the subdivision, then each building permit issued shall
be conditioned upon the incorporation of the approved recommended
corrective action in the construction of each structure; appeal of
such determination shall be to the city council.
(Ord. 88-O-117 § 1, 1988)
Soils tests shall be obtained by the developer after rough grading
and used to determine the structural section of all streets and alleys.
The structural section on private driveways, aisleways and stalls
within private parking lots shall be based on resistance to shear
(R-value) soils test. In the absence of such tests, the minimum structural
section shall be two inch asphaltic concrete on four inch aggregate
base or four inch asphaltic concrete on compacted native material.
The minimum structural section for public roadways shall be three
inches asphaltic concrete on five inches of aggregate base or six
inches of asphaltic concrete on compacted native material. All proposed
street construction within the right-of-way shall require prior written
approval of structural sections by the city engineer.
