RESOLUTION NO 25-0118
RESOLUTION OF THE CITY OF MANHATTAN BEACH CITY
COUNCIL MAKING EXPRESS FINDINGS AND
DETERMINATIONS THAT MODIFICATIONS TO THE 20 25
CALIFORNIA BUILDING CODE, CALIFORNIA
RESIDENTIAL CODE, CALIFORNIA ELECTRICAL CODE,
CALIFORNIA PLUMBING CODE, CALIFORNIA
MECHANICAL CODE, AND THE CALIFORNIA EXISTING
BUILDING CODE , AS ADOPTED BY THE CITY OF
MANHATTAN BEACH, ARE REASONABLY NECESSARY
BECAUSE OF LOCAL CLIMATIC, GEOLOGICAL OR
TOPOGRAPHICAL CONDITIONS
THE MANHATTAN BEACH CITY COUNCIL HEREBY FINDS AND RESOLVES AS FOLLOWS:
SECTION 1. Certain model and uniform codes, including the 20 25 California Building, Residential, Electrical, Plumbing, Mechanical, Existing, Green Building Standards, Energy, Administrative, Historical, and Referenced Standards Code located within Title 24 of the California Code of Regulations and including building standards therein, are adopted and amended by the State of California in the 20 25 California Building Standards Code. On January 1, 20 26, the 20 25 California Building Standards Code will become applicable in the City, subject to amendments made by the City pursuant to state law.
SECTION 2. Health and Safety Code Sections 17958.5 and 18941.5 permit local amendments to building standards adopted by the State, based upon express findings that such amendments are reasonably necessary due to local climatic, geological and/or topographical conditions. These amendments must be expressly marked and identified as to which each finding refers. Local amendments must be more restrictive than the building standards adopted by the State.
SECTION 3. The City Council finds that certain local climatic, geological, or topographical conditions exist as follows:
A. Climatic. The City experiences periods of extremely high temperatures accompanied by low humidity and high winds each year. These conditions create an environment in which there is an increased risk of fire.
B. Geological. Manhattan Beach is prone to seismic activity due to the existence of active earthquake faults in the Southern California area. Due to the high geologic activities in the Southern California area , amendments are required to address and clarify special needs for buildings constructed in a seismically active area. 1 of 6
C. Climatic. Precautionary steps are necessary to reduce or eliminate potential problems that may result from using timber footings in Manhattan Beach , as timber footings experience relatively rapid decay due to the fact that the region does not experience temperatures cold enough to destroy or retard the growth and proliferation of wood-destroying organisms. These conditions increase the likelihood of structural failure in the absence of Code amendments.
D. Topographical. The City is located in a densely populated coastal area in Los Angeles County that is more prone to high winds, earthquakes and fire, making it more difficult for Fire personnel to access than many other areas in California during emergencies.
E. Climatic. The City experiences periods of moist salt air which create an environment in which there is an increased rate of corrosion and greater likelihood of structural failure in the absence of Code amendments.
After due consideration, the City Council finds and determines that due to these local climatic, geological and topographical conditions, that amendments, additions and deletions to the 20 25 California Building Standards Code are reasonably necessary to provide sufficient and effective levels of safety for the protection of life, health and property. Specifically, the local conditions described above justify and require the following amendments:
