The Building Standards Commission adopts a compilation of building regulations every three years. These regulations, which are commonly referred to as the "Building Code," include: • California Building Code; • California Residential Code; • California Electrical Code; • California Mechanical Code; • California Plumbing Code; • California Energy Code; • California Historical Building Code; • California Existing Building Code; • California Referenced Standards Code; and • California Green Building Standards Code. The 2019 codes become effective on January 1, 2020, and apply to any project submitted for plan check thereafter. In order for the City of Downey to maintain its local amendments to the aforementioned codes, the City must readopt said amendments with the codes. The City Council introduced the ordinances at their November 20, 2019 meeting, and thus are scheduling this matter for public hearing at its January 14, 2020 meeting. Accordingly, a notice of the public hearing was published in the Downey Patriot for the forecasted hearing on this topic for the January 14, 2020 City Council Meeting. r •: Through the code adoption process, the Building Standards Commission selects and approves a model code that will apply statewide. The 2019 codes adopted by the Building Standards Commission strive to make all structures more energy efficient and structurally safer over the 2016 codes. As part of these codes, Chapters 11A and 11 B of the Building Code contain the accessibility standards for residential and commercial developments. In the State of California, these two chapters are consistent with, but enforced in lieu of, the American with Disability Act (ADA). Local jurisdictions are authorized to further modify the code to add more restrictive provisions based on their specific local geologic, climatic, and topographic conditions. All local amendments must be more restrictive than the State Codes and must be substantiated with findings, per California Health & Safety Code Section 17958. For the City of Downey, the "Building Code" is contained within Article VIII of the Municipal Code. The Building Standards Commission does not adopt the administration chapter of the California Codes therefor the City Council of Downey needs to adopt its own administration chapter. Local amendments are contained in the attached ordinances and are intended to address the unique conditions that the City of Downey incurs, such as being in a liquefaction area and large seismic 2019 BUILDING CODE JANUARY 14, 2020 PAGE 4 zone. The proposed local amendments are structural requirements consistent with local Los Angeles area cites and county. Accordingly, staff does not feel this additional restriction will create an undue burden on homeowners and developers.

The City Council hereby finds that the proposed amendments to the 2019 California Building Code are reasonably necessary because of local climatic, geologic of topographic conditions, and adopts the findings provided below to support the modifications to the 2019 California Building Code. The City Council further finds that some changes and modifications are of an administrative or procedural nature, or concern themselves with subjects not covered by the code, or are reasonably necessary to safeguard life and property within the City. The City Council hereby adopts the following (Climatic, geological, and topographical, where applicable) findings to support the proposed amendments to the 2019 California Building Code made in this Ordinance: I. Climatic Conditions A. The jurisdiction of the City of Downey (or, "City") is located in a semi -arid Mediterranean type climate. It annually experiences extended periods of high temperatures with little or no precipitation. For example, during July, August and September, temperatures often exceed 100 degrees Fahrenheit. During the same months humidity is usually less than 40%, and humidity measurements less than 10% are not uncommon. These conditions contribute to an increased likelihood of fire. Moreover, minor fires have a greater tendency of spreading rapidly due to such conditions. The City, being in the Southern California area, is also subject to "Sundowner" or "Santa Ana" winds that, should a fire occur, cause the fire to spread rapidly over wood shake roofs which are common in the residential areas. These hot, dry (Santa Ana) winds may reach speeds of 70 M.P.H. or greater. These climatic conditions cause extreme drying of vegetation and common building materials. Frequent periods of drought and low humidity add to the fire danger. This predisposes the area to large destructive fires (conflagration). In addition to directly damaging or destroying buildings, these fires are also prone to disrupt utility services throughout the City. Obstacles generated by a strong wind, such as fallen trees, street lights and utility poles, and the requirement to climb 75 feet vertically up flights of stairs will greatly impact the response time to reach an incident scene. Additionally, there is a significant increase in the amount of wind force at 60 feet above the ground. Use of aerial type fire -fighting apparatus above this height would place rescue personnel at increased risk of injury. B. Water demand in this densely populated area far exceeds the quantity supplied by natural precipitation; and although the population continues to grow, the already -taxed water supply does not. California is projected to increase in population by nearly 10 million over the next quarter of a century with 50 percent of that growth centered in Southern California. Due to storage capacities and consumption, and a limited amount of rainfall, future water allocation is not fully dependable. This necessitates the need for additional and on-site fire protection features. It would also leave tall buildings vulnerable to uncontrolled fires due to a lack of available water and an inability to pump sufficient quantities of available water to floors in a fire. C, These dry climatic conditions and winds contribute to the rapid spread of even small fires originating in high-density housing or vegetation. These fires spread very quickly and create a need for increased levels of fire protection. The added protection of fire sprinkler systems and other fire protection features will supplement normal fire department response by providing immediate protection for the building occupants and by containing and controlling the fire spread to the area of origin. Fire sprinkler systems will also reduce the use of water for firefighting by as much as 50 to 75 percent. Topographical conditions A. Development has occurred in the City and continues to occur in the City and such development has resulted in severe traffic congestion during peak business hours, weekends and holidays, thus decreasing the response time of fire and emergency service vehicles, particularly on the following streets and highways: Florence Avenue, Firestone Boulevard, Imperial Highway, Paramount Boulevard, Lakewood Boulevard, Brookshire Avenue, Bellflower Boulevard. B. These topographical conditions combine to create a situation which places fire department response time to fire occurrences at risk, and makes it necessary to provide automatic on-site fire -extinguishing systems and other protection • 1 r 1 0 measures to protect occupants and property. Due to these topographical conditions and the expected infrastructure damage inherent in seismic zones described below, it is prudent to rely on automatic fire sprinkler systems to mitigate extended fire department response time and keep fires manageable with reduced fire flow (water) requirements for a given structure. Numerous fires have occurred within the City in residential structures (houses, apartments, hotels, motels, and dormitories) over the past several years that have automatic fire protection systems, and in all of these fires, the automatic fire protection systems have successfully controlled and/or suppressed the fire before the emergency response personnel have been able to arrive at the structure. Additional fire protection is also justified to match the current resources of firefighting equipment and personnel within the fire department. Ill. Geological Conditions A. The City of Downey is located in Southern California, in an extremely active seismic region, with high levels of historic earthquake shaking in the recent past (earthquakes measuring larger than a magnitude 5 on the Richter Scale) and can be expected to experience significant strong ground shaking within the foreseeable future. The City is a densely populated area that has buildings constructed over and near a vast and complex network of faults that increase the likelihood of catastrophic damage when a seismic event occurs and which are believed to be capable of producing future earthquakes similar or greater in size to the 1994 Northridge, the 1987 Whittier Narrows Earthquake, the 1971 Sylmar earthquakes and 1933 Long Beach Earthquake. The seismotectonic setting of the City is dominated by the Norwalk fault, which traverses the northern portion of the City. The City is also in close proximity to the San Andreas Fault, which is located 40 miles to the northeast, the Whittier fault, located 10 miles to the northeast and the Newport -Inglewood fault, located 10 miles to the southwest. In the event of a severe earthquake, these faults present the potential for catastrophic damage, including fire, damage to roadways and other impairments of emergency apparatus. Existing and planned developments are at risk from structural damage from earthquake faults. Improved standards are necessary to ensure that maximum safety is provided to persons and property. B. Previous earthquakes have been accompanied by disruption of traffic flow and fires. A severe seismic event has the potential to negatively impact any rescue or fire suppression activities because it is likely to create obstacles similar to those indicated under the high wind section above. This situation creates the need for both additional fire protection and automatic on-site fire protection for building occupants. IV.

A high percentage of the population in Downey has a swimming pool. The fencing section has been amended considering the additional safety aspects to be considered; and, WHEREAS, the City of Downey has a low rainfall average which contributes to dust and debris being scattered by winds. This has been addressed by way of amendments to this code. NOW, THEREFORE, THE CITY COUNCIL OF THE'CITY OF DOWNEY DOES HEREBY ORDAIN AS FOLLOWS: SECTION 1: Findings. The City Council hereby finds that the proposed amendments to the 2019 California Residential Code are reasonably necessary because of local climatic, geologic of topographic conditions, and adopts the findings provided below to support the modifications to the 2019 California Residential Code. The City Council further finds that some changes and modifications are of an administrative or procedural nature, or concern themselves Attachment "" with subjects not covered by the code, or are reasonably necessary to safeguard life and property within the City. The City Council hereby adopts the following (Climatic, geological, and topographical, where applicable) findings to support the proposed amendments to the 2019 California Residential Code made in this Ordinance: Climatic Conditions A. The jurisdiction of the City of Downey (or, "City") is located in a semi -arid Mediterranean type climate. It annually experiences extended periods of high temperatures with little or no precipitation. For example, during July, August and September, temperatures often exceed 100 degrees Fahrenheit. During the same months humidity is usually less than 40%, and humidity measurements less than 10% are not uncommon. These conditions contribute to an increased likelihood of fire. Moreover, minor fires have a greater tendency of spreading rapidly due to such conditions. The City, being in the Southern California area, is also subject to "Sundowner" or "Santa Ana" winds that, should a fire occur, cause the fire to spread rapidly over wood shake roofs which are common in the residential areas. These hot, dry (Santa Ana) winds may reach speeds of 70 M.P.H. or greater. These climatic conditions cause extreme drying of vegetation and common building materials. Frequent periods of drought and low humidity add to the fire danger. This predisposes the area to large destructive fires (conflagration). In addition to directly damaging or destroying buildings, these fires are also prone to disrupt utility services throughout the City. Obstacles generated by a strong wind, such as fallen trees, street lights and utility poles, and the requirement to climb 75 feet vertically up flights of stairs will greatly impact the response time to reach an incident scene. Additionally, there is a significant increase in the amount of wind force at 60 feet above the ground. Use of aerial type fire -fighting apparatus above this height would place rescue personnel at increased risk of injury. B. Water demand in this densely populated area far exceeds the quantity supplied by natural precipitation; and although the population continues to grow, the already -taxed water supply does not. California is projected to increase in population by nearly 10 million over the next quarter of a century with 50 percent of that growth centered in Southern California. Due to storage capacities and consumption, and a limited amount of rainfall, future water allocation is not fully dependable. This necessitates the need for additional and on-site fire protection features. It would also leave tall buildings vulnerable to uncontrolled fires due to a lack of available water and an inability to pump sufficient quantities of available water to floors in a fire. C. These dry climatic conditions and winds contribute to the rapid spread of even small fires originating in high-density housing or vegetation. These fires spread very quickly and create a need for increased levels of fire protection. The added protection of fire sprinkler systems and other fire protection features will supplement, normal fire department response by providing immediate protection for the building occupants and by containing and controlling the fire spread to the area of origin. Fire sprinkler systems will also reduce the use of water for firefighting by as much as 50 to 75 percent. : II. Topographical conditions A. Development has occurred in the City and continues to occur in the City and such development has resulted in severe traffic congestion during peak business hours, weekends and holidays, thus decreasing the response time of fire and emergency service vehicles, particularly on the following streets and highways: Florence Avenue, Firestone Boulevard, Imperial Highway, Paramount Boulevard, Lakewood Boulevard, Brookshire Avenue, Bellflower Boulevard. B. These topographical conditions combine to create a situation which places fire department response time to fire occurrences at risk, and makes it necessary to provide automatic on-site fire -extinguishing systems and other protection measures to protect occupants and property. Due to these topographical conditions and the expected infrastructure damage inherent in seismic zones described below, it is prudent to rely on automatic fire sprinkler systems to mitigate extended fire department response time and keep fires manageable with reduced fire flow (water) requirements for a given structure. Numerous fires have occurred within the City in residential structures (houses, apartments, hotels, motels, and dormitories) over the past several years that have automatic fire protection systems, and in all of these fires, the automatic fire protection systems have successfully controlled and/or suppressed the fire before the emergency response personnel have been able to arrive at the structure. Additional fire protection is also justified to match the current resources of firefighting equipment and personnel within the fire department. III. Geological Conditions A. The City of Downey is located in Southern California, in an extremely active seismic region, with high levels of historic earthquake shaking in the recent past (earthquakes measuring larger than a magnitude 5 on the Richter Scale) and can be expected to experience significant strong ground shaking within the foreseeable future. The City is a densely populated area that has buildings constructed over and near a vast and complex network of faults that increase the likelihood of catastrophic damage when a seismic event occurs and which are believed to be capable of producing future earthquakes similar or greater in size to the 1994 Northridge, the 1987 Whittier Narrows Earthquake, the 1971 Sylmar earthquakes and 1933 Long Beach Earthquake. The seismotectonic setting of the City is dominated by the Norwalk fault, which traverses the northern portion of the City. The City is also in close proximity to the San Andreas Fault, which is located 40 miles to the northeast, the Whittier fault, located 10 miles to the northeast and the Newport -Inglewood fault, located 10 miles to the southwest. In the event of a severe earthquake, these faults present the potential for catastrophic damage, including fire, damage to roadways and other impairments of emergency apparatus. Existing and planned developments are at risk from structural damage from earthquake faults. Improved standards are necessary to ensure that maximum safety is provided to persons and property. B. Previous earthquakes have been accompanied by disruption of traffic flow and fires. A severe seismic event has the potential to negatively impact any rescue or fire suppression activities because it is likely to create obstacles similar to those indicated under the high wind section above. This situation creates the need for both additional fire protection and automatic on-site fire protection for building occupants. IV.
