15.04.050 Modifications to the California Building Code. Revised 12/16

A. The following local geologic conditions justify modifications to California Building Standards Code as detailed in subsection B of this section:

Geological – The region is located in an area of high seismic activities as indicated by United States Geological Survey and California Division of Mines and Geology. Recent earthquake activities have indicated the lack of flexibility of materials and/or building systems has been a contributing factor to damages that reduced the usability of buildings, degraded the life-safety of building occupants, and increased the cost of rehabilitation of the structures.

B. The following modifications apply to the California Building Code:

1805.3.1. Concrete floors in all residential occupancies shall be protected from moisture penetration by a bed of at least three inches of clean rock, not less than 3/8 inch nor more than 1 inch in diameter. Dam proofing consisting of not less than 10-mil polyethylene with joints lapped not less than 12 inches, a vapor barrier that meets or exceeds ASTM E-1745 Standards, or other approved methods or materials shall be installed beneath the slab. Joints in the membrane shall be lapped and sealed in accordance with the manufacturer's installation instructions.

Section 1905.1.8. Amends ACI 318 section 22.10.1 of ACI 318 that allows the use of plain concrete in residential structures assigned to seismic design category D, E or F to read:

22.10. Plain concrete in structures assigned to seismic design category C, D, E or F.

22.10.1. Structures assigned to Seismic Design Category C, D, E or F shall not have elements of structural plain concrete, except as follows:

(a) Isolated footings of plain concrete supporting pedestals or columns are permitted, provided the projection of the footing beyond the face of the supported member does not exceed the footing thickness.

Exception: In detached one and two-family dwelling three stories or less in height, the projection of the footing beyond the face of the supported member is permitted to exceed the footing thickness.

(b) Plain concrete footing supporting walls are permitted, provided the footings have at least two continuous longitudinal reinforcing bars. Bars shall not be smaller than No. 4 and shall have a total area of not less than 0.002 times the gross cross-sectional area of the footing. A minimum of one bar shall be provided at the top and bottom of the footing. Continuity of reinforcement shall be provided at corners and intersections.

Exception: In detached one and two-family dwellings three stores or less in height and constructed with stud bearing walls, plain concrete footings with at least two continuous longitudinal reinforcing bars not smaller than No. 4 are permitted to have a total area of less than 0.002 times the gross cross-sectional area of the footing.

(Ord. 1007 § 3, 2016: Ord. 987 § 3, 2014: Ord. 927 § 2, 2007; Ord. 842 § 2, 2002)
