NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF SANTA MONICA DOES HEREBY ORDAIN AS FOLLOWS:
4 SECTION 1. The City Council makes the following findings regarding local climatic, geological, and topographical conditions related to the local amendments to the California Building Standards Code described in Section 2 below:
General Findings
a) The Master Environmental Assessment (“MEA”) adopted in April 1996, shows that Santa Monica’s climate is primarily influenced by the Pacific Ocean and is characterized by infrequent rainfall and winds. The winds originate from the west during the day and from the north and northeast during the night. Further, intermittent Santa Ana winds conditions occur from September to March allowing conditions that create the potential for high velocity winds with high temperatures. In addition, the region is within a climate system capable of producing major winds, fire, and rain related disasters, including but not limited to those caused by the Santa Ana winds and El Nino (or La Nina) subtropical-like weather. (Climatic) b) Santa Monica is situated in Southern California which has extreme arid conditions and periods of severe drought. As outlined in the MEA, the City relies for its water supply upon water from outside the region which is purchased from the Metropolitan Water District and local groundwater. (Climatic). c) The Safety Element of Santa Monica’s General Plan, adopted in February 2025, shows that Santa Monica is in area at high risk of seismic activity due to, among other fault systems, the Santa Monica, Newport-Inglewood, and the San Andreas fault systems, the close proximity of which increases the likelihood of seismic disturbances of substantial magnitude. The Safety Element further discusses the damaging effect local seismic activity would have on potentially hazardous buildings and the related 5 potential demands on emergency service needs. (Geological) d) The Los Angeles region has a vast and complex network of faults. Some of these faults, like the previously unknown Northridge Fault, are blind thrust faults that earth scientists believe are capable of intense ground shaking similar or greater in size than the January 17, 1994 Northridge Earthquake. The random possible location of these blind thrust faults increases the local seismic risk and poses an increasing threat to public safety. (Geological)
e) The Safety Element also identifies shallow ground water within 50 feet of the ground surface along the beach, near the Industrial corridor and Marine Park areas of the City. This ground water condition, coupled with unconsolidated youthful sedimentary soils, makes these areas susceptible to possible liquefaction during strong or moderately strong earthquakes. Liquefaction is a very destructive secondary effect of strong seismic shaking where a loss of bearing strength occurs along with ground oscillations in the supporting soils. (Geological) f) Existing lots in the City of Santa Monica may be located on hilly terrain with slopes that create grading, drainage, foundation, infrastructure, utility and emergency access challenges. (Topographical)
g) Where climatic conditions in Santa Monica create demands for higher usage of energy and natural resources, measures that allow conservation and efficiencies in construction will promote practices to achieve these goals and will be better realized with a definition of Sustainability as applied to concepts in the California Green Building Standards Code. (Climatic)
h) The greater Los Angeles region is a densely populated area having 6 residential buildings constructed within a region where environmental resources are scarce due to varying and occasional immoderate temperatures and weather conditions. This local condition also challenges the demand and need for energy resources upon the local utilities. (Climatic)
i) Modifications and changes to administrative standards for the effective enforcement of building standards as well as modifications and changes that do not result in substantive changes to the California Building Standards, do not modify Building Standards pursuant to Sections 17958 and 18941.5 of the California Health and Safety Code, and do not require express findings of local climatic, geological, or topographical conditions to be made to justify them pursuant to Sections 17958.5 and 17958.7 of the California Health and Safety Code. (Administrative) j) Unless otherwise noted, the proposed amendments are substantially similar to amendments that were previously adopted by Council and were in effect as of September 30, 2025, or fall under one of the other exceptions in AB 130, including, but not limited to home hardening and/or administrative practices related to enforcement of code violations.

Metallic enclosures that are located within 402.4 meters (0.25 miles) of the mean shoreline are especially subject to corrosive conditions The proposed modifications to metallic enclosures located within 26 402.4 meters (0.25 miles) of the mean shoreline will increase resilience and protect against corrosion. (Climatic).
aaa)The Santa Monica Mountains’ proximity and prevailing onshore wind patterns, which heighten ember cast and fire spread risk. The dense urban layout of the City, which amplifies the threat of structure-to-structure ignition in the event of a wildfire event. The proposed amendment to the Wildland-Urban Interface Code ensures that hazardous vegetation management requirements apply consistently across lands within City boundaries that are designated as High and/or Very High Fire Hazard Severity Zones (FHSZ). These clarifications are necessary to implement defensible space standards to proactively address vegetation hazards that may contribute to structure loss or fire spread in WUI conditions. The proposed changes support home hardening by reducing the likelihood of ignition from vegetation and fuels within high-risk WUI zones. While “home hardening” is often associated with structural features (e.g., ember-resistant vents, fire-resistant roofing), defensible space and vegetation clearance are explicitly recognized as critical wildfire mitigation strategies that contribute to the survivability of buildings in fire-prone areas—therefore falling under the broader umbrella of “home hardening” as recognized by CalFire and the State Fire Marshal.
Green Standards Code Findings - General Findings
(G)(a). It is expected that climate change will result in more severe and frequent drought and extreme heat events, intensifying local heat islands and putting vulnerable populations at health risk. (Climatic)
27 (G)(b). Due to changes in rainfall patterns expected with climate change, the City of Santa Monica is likely to be subject to more severe weather events, including droughts as well as more intense storms that increase the risks of wildfire, erosion, overland local flooding and landslides. (Climatic and Environmental) (G)(c). The greater Los Angeles region is a densely populated area having buildings constructed within a region where environmental resources are scarce due to varying and occasional immoderate temperatures and weather conditions. (Climatic and Environmental)
(G)(d). Failure to address and significantly reduce greenhouse gas (GHG) emissions could result in rises in sea level that could put at risk Santa Monica homes, businesses, and public facilities. (Climatic and Geological) (G)(e). The State of California enacted Senate Bill (SB) 32 to require greenhouse gas emissions to be reduced to 40 percent below 1990 levels by 2030. (G)(f). The City of Santa Monica is committed to reducing greenhouse gas emissions in accordance with the United States’ original commitment to the Paris Climate Accord.
Green Standards Code Findings - Specific Findings
(G)(g). The local amendments to require the use of low-carbon concrete will encourage the substitution of carbon intensive Portland cement for less carbon intensive alternative cementitious materials, promote a lower contribution to GHG emissions, and increase resilience to ongoing climate change. (Climatic and Environmental)
