CHAPTER 21. SUBDIVISIONS.
Article 4. Filing of Tentative Map.
Sec. 21-4-8. Soils investigation.
(a) A preliminary soils report, prepared by a registered civil engineer
and based upon adequate test borings, shall be required for every subdivision
for which a tentative map is required. The preliminary soils report shall be
submitted with the map application for review. Upon such review, the city may
require additional information or reject the report if it is found to be
incomplete, inaccurate or unsatisfactory.
(b) The preliminary soils report
requirement may be waived if the city engineer determines that, due to the
knowledge the city has as to the qualities of the soils of the subdivision, no
preliminary analysis is necessary.
(c) A soils investigation of each
potentially affected lot in the subdivision may be required by the city engineer
as a condition precedent to consideration of the tentative map by the planning
commission if the preliminary soils report indicates:
(1) The presence of
critically expansive soils or other soils problems which, if not corrected,
would lead to structural defects; or
(2) The presence of rocks or liquids
containing deleterious chemicals which, if not corrected, could cause
construction materials such as concrete, steel and ductile or cast iron to
corrode or deteriorate.
(d) Any soils investigation required pursuant to
this section shall be done by a registered civil engineer who shall recommend
the corrective action likely to prevent structural damage to each structure
proposed to be constructed in the area where the soils problem exists. The
planning commission may approve or conditionally approve a tentative map, if it
determines that the recommended corrective action is likely to prevent
structural damage to each structure to be constructed. Such recommended
corrective action shall be required to be incorporated in the construction of
each structure as a condition to the issuance of any building permit. (Ord. No.
1500, § 3 (part).)
