The City Council makes the following findings regarding local climatic, geological and topographic conditions related to the local amendments to the California Building Standards Code found in Section 2 below: (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, which come from the west during the daytime and from the north and northeast during the nighttime, with intermittent Santa Ana winds occurring from September to March These conditions create the potential for high velocity winds with high temperatures, which are conducive to uncontrolled wind driven fires and greatly increase the fire rise to residences 3 (b) The MEA also shows that structures in the City are situated in close proximity to each other, with only about 1 % of the 8.3 square miles that the City occupies vacant. In addition, these lots are often very narrow or on hilly terrain, which limits access to side yards for fire suppression and placement of ladders for rescue operations. These conditions also contribute to the ability of fires to spread quickly between buildings because of the proximity to each other and create difficulty in suppressing fires in the hilly terrains. (c) The Safety Element also identifies that many of the structures in the City are older structures that are prone to the quick spread of fire from adjacent structures due to the materials used in construction and less stringent fire resistant technology available at the time they were built. (d) 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 upon water from outside the region, which is bought from the Metropolitan Water District, and local groundwater for the City's water supply. Severe drought conditions and potential uncertainty about the availability of future water supplies from outside the region require the proper management of available water supplies. These conditions also contribute to the ability of fires to spread quickly due to the reliance of water from outside sources that may not be available following a major earthquake. (e) The Safety Element shows a high risk of seismic activity in the City due to the close proximity to the Santa Monica-Malibu Coast fault, the Newport- Inglewood fault and the San Andreas fault, and discusses the damaging effect 4 local seismic activity would have on potentially hazardous buildings and the related potential demands on emergency services needs. Structures built without supplemental seismic provisions are susceptible to extensive damage and are a source of fire hazard with damaged gas and electrical utilities inside. The close proximity of these faults increases the likelihood of seismic disturbances of substantial magnitude. (f) 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 Northridge Earthquake. The random possible location of these blind thrust faults increases the local seismic risk and poses an increasing threat to public safety. (g) The Safety Element of the General Plan, adopted in January 1995, shows high risk of seismic activity in the City due to the close proximity of the City to the Santa Monica-Malibu Coast fault, the Newport-Inglewood fault and the San Andreas Fault. The Safety Element discusses the damaging effect local seismic activity would have on street, roadways and overpasses at the Santa Monica Freeway, which would hamper and delay emergency vehicle response. (h) An analysis of damage patterns to structures in the City from the January 17, 1994 Northridge earthquake and its aftershocks showed that unreinforced masonry structures, wood frame structures, tilt-up and masonry structures with flexible diaphragms, non-ductile concrete buildings, and steel frame structures, were more susceptible to damage than other types of 5 structures. Unless supplemental seismic and fire life safety prevention requirements are adopted, these buildings will perform poorly during intense ground shaking and will pose an ongoing threat to public safety. (i) An analysis of damage patterns to nonstructural elements in the City from. the January 17, 1994 Northridge earthquake and its aftershocks also showed that concrete and masonry chimneys, veneer, clay and concrete tile roofing and fire sprinklers were more susceptible to damage than other types of nonstructural elements. Unless supplemental seismic and fire life safety provisions are adopted, these nonstructural elements will perform poorly during intense ground shaking and pose an ongoing threat to public safety. U) Continued study of buildings damaged during the Northridge Earthquake has led to improvements in earthquake design regulations that better identify the types of buildings that are vulnerable to earthquakes and cost effective economic methods to construct them. (k) By incorporating the latest earthquake design regulations into the City's building standards, the latest and most effective standards will be implemented into design and construction so that the public health and welfare will be better protected. (I) 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 6 very destructive secondary effect of strong seismic shaking where a loss of bearing strength occurs along with ground oscillations in the supporting soils. Analysis of the emergency response to the January 17 1994 earthquake showed that the need for emergency fire services in the City greatly exceeded available resources. A major seismic event would create a demand for fire suppression services that the City Fire Department would have difficulty meeting, thus making supplemental seismic safety provisions essential to fire suppression efforts. SECTION 2. The City Council makes the express finding that the following modifications and changes to the California Building Standards Code are reasonably necessary because of the local climatic, geological or topographical conditions and that each and every one of the local conditions detailed in Section 1 above, are identified as applying to the following modifications and changes to the California Building Standards Code: Require the engineer or architect of record to verify that their structural designs are followed during construction (see Section 8.08.120). Adopt necessary appendices to the Building Code that include provisions for Use or Occupancy, Aviation Control Towers, Sound Control Transmission, Re-roofing, Structural Forces, Waterproofing and Damproofing Foundations, Minimum Plumbing Fixtures, Membrane Structures, Excavation and Grading, Existing Buildings, and Material, Testing and Installation Standards (see Section 8.12.030). 7 Establish Seismic Hazard Zones and Geologic Hazard Filled Area Zones to require special design requirements (see Section 8.12.050). Prohibit the use of non-fire retardant wood shingles or non-fire retardant wood shakes for new or replacement roofing and require a moderate level of fire retardant roofing as a minimum standard (see Section 8.12.060). Establish earthquake design provisions that properly account for dead load effects during earthquakes, limit shear-critical behavior in concrete and masonry shear walls and properly calculate the allowable story drift under earthquake loading (see Section 8.16.020). Require improved connection of roofing to prevent slippage during earthquakes and the associated falling hazards (see Section 8.16.030). Require all masonry and concrete chimneys to be structurally designed by a licensed architect or registered engineer instead of by prescriptive rules that have allowed failed performance in recent earthquakes, including the Northridge Earthquake (see Section 8.16.040). Provide the most current seismic provisions for steel frame and light gage steel stud buildings that incorporate the lessons learned to date from the Northridge Earthquake instead of the outdated Pre-Northridge reference standards (1992) in the California Building Code (see Section 8.16.050). Require the most current seismic provisions for wood frame construction to limit the use of materials that have proved ineffective in resisting earthquake forces and require additional engineering analysis (see section 8.16.060 and Chapter 8.20). 8 Require automatic fire extinguishing and detection systems in all new construction and when there is a change in use to a higher classification (See Section 8.44.050). Require automatic fire sprinkler systems for existing public assembly spaces above 5,000 square feet that protect assembly areas and exit ways (See Section 8.44.050). Require compliance with the high-rise provisions of the California Building Code in new high-rise buildings with human occupancy above 55 feet of the lowest level of fire vehicle access point in accordance with authority granted to the City in the California Health and Safety Code Section 13216 (See Section 8.44.090). Require adequate seismic bracing of fire sprinkler installations (see Section 8.44.120). Ensure that any wiring not having metal protection over the conductors shall be entirely concealed within the building structure to prevent and inhibit tampering and restrict the use of aluminum wiring found to be hazardous (see Section 8.24.030). Prohibit the sale and use of any electrical material, device, or equipment unless it complies with provisions of this section, including rating and conformance with national standards (see Section 8.24.040). Provide regulations for temporary service poles used on construction sites (see Section 8.24.060) Provide regulations for underground concrete vaults and 9 hand holes (see Section 8.24.070). Provide proper disconnecting means for multiple arrays on solar photovoltaic systems (see Section 8.24.080). Provide sufficient gage support of grease ducts during earthquakes (see Section 8.28.030). Require the use of Type fire protective hoods for all cooking ovens that cook food with grease (see Section 8.28.040). (21) Provide for the use of refrigeration machinery rooms for all refrigerants in rooms with over 100 HP motors above maximum threshold amounts instead of just the least toxic and flammable (see Section 8.28.050). (22) Provide for the use of the proper table values from American Society of Heating, Refrigeration and Air Conditioning Engineers to determine the allowable quantities of the refrigerants R-123 and R-55 in Table 11-1 of the California Mechanical Code (see Section 8.08.060). Provide for enclosures of water heaters to prevent associated fire hazards from uncontrolled adjacent combustible storage (see Section 8.32.030). Prohibit water softener systems from using drywells to discharge effluents in order to protect local ground water and the Santa Monica Bay (see Section 8.32.040). Prohibit the use of combined storm drain and sewers to prevent the possible future contamination of the Santa Monica Bay (see Section 8.32.050). Require automatic fire extinguishing and detection systems in all new construction and when there is a change in use to a higher classification 10 (See Section 8.44.050). (27) Require automatic fire sprinkler systems for existing public assembly spaces above 5,000 square feet that protect assembly areas and exit ways (See Section 8.44.050). Require compliance with the high-rise provisions of the California Building Code in new high-rise buildings with human occupancy above 55 feet of the lowest level of fire vehicle access point in accordance with authority granted to the City in the California Health and Safety Code Section 13216 (See Section 8.44.090). Require the connection with control valves on each floor level with full automatic sprinkler systems in any new building with floors more than 55 feet in height (See Section 8.44.090). Require adequate seismic bracing of fire sprinkler installations (see Section 8.44.120). SECTION 3. The City Council makes the following findings regarding local climatic, geological and topographic conditions related to the local amendments to the California Building Standards Code found in Section 4 below: (a) As detailed in the MEA, although the City can experience periods of high winds and arid temperatures, it often enjoys an extremely mild climate. Average daytime temperatures range from highs of 75 degrees (F) in July, August, and September to 64 degrees (F) in January and February. Overnight lows vary from an average of 61 degrees (F) in January and February to 64 11 degrees (F) in August. A below freezing temperature has never been recorded in the City. The City's annual precipitation averages 12.5 inches. The City has excellent air quality and the City, unlike most of the South Coast Air Basin, seldom exceeds national and state air quality standards. This temperate climate makes the City uniquely suited for the proper operation of buildings designed for sustainable development and increased use of openable windows. SECTION 4. The City Council makes the express finding that the following modifications and changes to the California Building Standards Code are reasonably necessary because of the local climatic, geological or topographical conditions and that each and every one of the local conditions shown in Section 3 above, are identified as applying to the following modifications and changes to the California Building Standards Code: (1) Require guardrails at openable windows and provide clarifying language (see Section 8.12.060). (2) Require cost effective energy efficiency in multi-family residences, hotels, motels, commercial and institutional offices, light industrial and retail uses pursuant to the Green Building Standards (see Sections 8.108.040), (3) Require additional mandatory energy efficiency measures for Solar Water Heating, Pipe Insulation and Heat Traps in all buildings (see Section 8.108.060). SECTION 5. The City Clerk shall certify to the adoption of this Resolution and thenceforth and thereafter the same shall be in full force and effect. 12 APPROVED AS TO FORM ~ OUTRIE 13 Adopted....
