Section 17953 Of Chapter 4. Application And Scope From California Health And Safety Code >> Division 13. >> Part 1.5. >> Chapter 4.
17953
. Each city, county, and city and county shall enact an
ordinance which requires a preliminary soil report, prepared by a
civil engineer who is registered by the state, based upon adequate
test borings or excavations, of every subdivision, where a tentative
and final map is required pursuant to Section 66426 of the Government
Code.
The preliminary soil report may be waived if the building
department of the city, county or city and county, or other
enforcement agency charged with the administration and enforcement of
the provisions of this part, shall determine that, due to the
knowledge such department has as to the soil qualities of the soil of
the subdivision or lot, no preliminary analysis is necessary.
