Health and Safety Code Sections 17958.5, 17958.7 and 18941.5 require that for each proposed local change to those provisions in the uniform codes and published in the California Building Standards Code which regulate buildings used for human habitation, the city council must make findings supporting its determination that each such local change is reasonably necessary because of local climatic, geological, or topographical conditions. Furthermore, California Green Building Standards Code Section 101.7.1 provides that local climatic, geological or topographical conditions include environmental conditions established by a city, county, or city and county.

Carlsbad has many brush-covered hillsides and protected natural open space areas adjacent to developed areas. Though relatively moderate compared to inland portions of the region, the seasonal climatic conditions during the late summer and fall in Carlsbad are characterized by frequent Santa Ana weather patterns. Santa Ana conditions are dry, hot, strong and gusty winds that produce March 12, 2019 Item #7 Page 15 of 43 Attachment "A" to Ordinance No. CS-347 extreme dryness and some of the highest winds in San Diego County, have fanned the region's most catastrophic wildfires and can impact public health in the populated coastal zone by the extreme heat and occasional smoke.1 Carlsbad has experienced larger increases in annual temperature than other parts of the state. Compared to the first six decades of the 20th century, annual temperatures have increased by more than 1 °Fin many parts of the state, with some areas (including the San Diego region) exceeding 2°F.2 This heating is expected to continue well into the future, with estimates ranging between 4-6°F and 7-9°F by the end of the century.3 T This amendment is justified on the basis of a local topographical condition. Carlsbad has six and a half miles of beaches, three lagoons, several creeks and other low-lying areas prone to flooding. The San Diego Multi-jurisdictional Hazard Mitigation Plan ranks coastal storm, erosion and flooding among the top five hazards for Carlsbad, with potential property loss exposure approaching $200 million dollars.4 There is broad scientific consensus that the earth will continue to warm and that sea levels will rise as a result of thermal expansion of the oceans and increased contributions from melting glaciers. By the end of the century, sea level could rise by 1. 7 to 6.6 feet, inundating beaches and impacting miles of roads and public accesses, the state campgrounds, hundreds of properties, and more than 1,000 acres of environmentally sensitive lands in Carlsbad.5 E This amendment is justified on the basis of local environmental conditions. Sustainability is a core value of the Community Vision, and an intrinsic part of the Carlsbad General Plan. Energy efficiency enhances the public health and welfare by promoting the environmental and economic health of the city through incorporating green practices into the design, construction, maintenance and operation of new and existing buildings. Installation of renewable energy systems to provide a building's energy and water heating needs enhances the public health and welfare by reducing air pollution and greenhouse gas (GHG) emissions that come from fossil fuel combustion. The amendments to the California Green Building Standards Code and Energy Code are reasonably necessary to achieve the following goals of the General Plan Sustainability Element and Carlsbad Climate Action Plan: • Promote energy efficiency and conservation in the community; • Pursue the use of sustainable energy sources; • Reduce the community's greenhouse gas emissions and foster green development patterns; • Maintain a long-term balance among environmental, social and economic concerns, to 1 Kalansky, Julie, Dan Cayan, Kate Barba, Laura Walsh, Kimberly Brouwer, Dani Boudreau.

The above-listed conditions within the city pose local hazards for which amendments to the California Green Building Standards Code and California Energy Code are required. Human activities that release heat-trapping greenhouse gases into the atmosphere (such as through fossil fuel combustion) are the primary driver of climate change.6 Failure to address and significantly reduce GHG emissions could result in increased extreme heat events, dry weather conditions and risk of wildfire. Rises in sea level, including in the city's lagoons, could put at risk Carlsbad homes and businesses, public facilities, pub Ii c roads (especially Carlsbad Boulevard) and accessways. According to the Carlsbad Climate Action Plan, community-wide GHG emissions need to be reduced 49 percent by 2035 to help achieve statewide reduction targets necessary to reduce impacts from climate change. Residential land uses account for 25 percent of the community's GHG emissions, while commercial and industrial uses are responsible for about 32 percent. Implementation of energy efficiency, photovoltaic energy and alternative water heating systems in new and existing res_idential and nonresidential buildings will significantly reduce emissions from these uses. 6 U.S. Global Research Program.

Health and Safety Code Sections 17958.5, 17958.7 and 18941.5 require that for each proposed local change to those provisions in the uniform codes and published in the California Building Standards Code which regulate buildings used for human habitation, the city council must make findings supporting its determination that each such local change is reasonably necessary because of local climatic, geological, or topographical conditions. Furthermore, California Green Building Standards Code Section 101.7.1 provides that local climatic, geological or topographical conditions include environmental conditions established by a city, county, or city and county.

Carlsbad has many brush-covered hillsides and protected natural open space areas adjacent to developed areas. Though relatively moderate compared to inland portions of the region, the seasonal climatic conditions during the late summer and fall in Carlsbad are characterized by frequent Santa Ana weather patterns. Santa Ana conditions are dry, hot, strong and gusty winds that produce extreme dryness and some of the highest winds in San Diego County, have fanned the region's most catastrophic wildfires and can impact public health in the populated coastal zone by the extreme heat and occasional smoke.1 Carlsbad has experienced larger increases in annual temperature than other parts of the state. · Compared to the first six decades of the 20th century, annual temperatures have increased by more than 1 °F in many parts of the state, with some areas (including the San Diego region) exceeding 2°F.2 This heating is expected to continue well into the future, with estimates 1 Kalansky, Julie, Dan Cayan, Kate Barba, Laura Walsh, Kimberly Brouwer, Dani Boudreau.

March 12, 2019 Item #7 Page 25 of 43 Attachment "A" to Ordinance No. CS-348 ranging between 4-6°F and 7-9°F by the end of the century.3 T This amendment is justified on the basis of a local topographical condition. Carlsbad has six and a half miles of beaches, three lagoons, several creeks and other low-lying areas prone to flooding. The San Diego Multi-jurisdictional Hazard Mitigation Plan ranks coastal storm, erosion and flooding among the top five hazards for Carlsbad, with potential property loss exposure approaching $200 million dollars.4 There is broad scientific consensus that the earth will continue to warm and that sea levels will rise as a result of thermal expansion of the oceans and increased contributions from melting glaciers. By the end of the century, sea level could rise by 1. 7 to 6.6 feet, inundating beaches and impacting miles of roads and public accesses, the state campgrounds, hundreds of properties, and more than 1,000 acres of environmentally sensitive lands in Carlsbad.5 E This amendment is justified on the basis of local environmental conditions. Sustainability is a core value of the Community Vision, and an intrinsic part of the Carlsbad General Plan. Energy efficiency enhances the public health and welfare by promoting the environmental and economic health of the city through incorporating green practices into the design, construction, maintenance and operation of new and existing buildings. Installation of renewable energy systems to provide a building's energy and water heating needs enhances the public health and welfare by reducing air pollution and greenhouse gas (GHG) emissions that come from fossil fuel combustion. The amendments to the Energy Code are reasonably necessary to achieve the following goals of the General Plan Sustainability Element and Carlsbad Climate Action Plan: • Promote energy efficiency and conservation in the community; • Pursue the use of sustainable energy sources; • Reduce the community's greenhouse gas emissions and foster green development patterns; • Maintain a long-term balance among environmental, social and economic concerns, to ensure a vibrant, healthy and prosperous community. The above-listed conditions within the city pose local hazards for which amendments to the California Energy Code are required. Human activities that release heat-trapping greenhouse gases into the atmosphere (such as through fossil fuel combustion) are the primary driver of climate change.6 Failure to address and significantly reduce GHG emissions could result in increased extreme heat events, dry weather conditions and risk of wildfire. Rises in sea level, including in the city's lagoons, could put at risk Carlsbad homes and businesses, public facilities, pub Ii c roads (especially Carlsbad Boulevard) and accessways. According to the Carlsbad Climate Action Plan, community-wide GHG emissions need to be reduced 49 percent by 2035 to help achieve statewide reduction targets necessary to reduce impacts from 3 San Diego Summary Report, p. 19. 4 2017 San Diego Multi-jurisdictional Hazard Mitigation Plan, Table 5.3-1. 5 City of Carlsbad.

BREWER, City Attorney March 12, 2019 Item #7 Page 39 of 43 Attachment "A" to Ordinance No. CS-349 FINDINGS FOR LOCAL AMENDMENTS TO 2016 CALIFORNIA GREEN BUILDING STANDARDS CODE California Health and Safety Code Section 17958 provides that the city may make changes to the provisions in the uniform codes that are published in the California Building Standards Code. Health and Safety Code Sections 17958.5, 17958.7 and 18941.5 require that for each proposed local change to those provisions in the uniform codes and published in the California Building Standards Code which regulate buildings used for human habitation, the city council must make findings supporting its determination that each such local change is reasonably necessary because of local climatic, geological, or topographical conditions. Furthermore, California Green Building Standards Code Section 101.7.1 provides that local climatic, geological or topographical conditions include environmental conditions established by a city, county, or city and county. California Green Building Standards Code Section Title Add Amend Justification 202 Definitions ✓ C, T, E 4.102.1 Definitions ✓ C, T, E Electric vehicle (EV) charging for new C, T, E 4.106.4 construction and major residential ✓ renovations 5.102.1 Definitions ✓ C, T, E 5.106.5.3 Electric vehicle charging ✓ C, T, E Key to Justification for Amendments to Title 24 of the California Code of Regulations C This amendment is justified on the basis of a local climatic condition. Carlsbad has many brush-covered hillsides and protected natural open space areas adjacent to developed areas. Though relatively moderate compared to inland portions ofthe region, the seasonal climatic conditions during the late summer and fall in Carlsbad are characterized by frequent Santa Ana weather patterns. Santa Ana conditions are dry, hot, strong and gusty winds that produce extreme dryness and some of the highest winds in San Diego County, have fanned the region's most catastrophic wildfires and can impact public health in the populated coastal zone by the extreme heat and occasional smoke.1 Carlsbad has experienced larger increases in annual temperature than other parts of the state. Compared to the first six decades of the 20th century, annual 1 Kalansky, Julie, Dan Cayan, Kate Barba, Laura Walsh, Kimberly Brouwer, Dani Boudreau. (University of California, San Diego). 2018. San Diego Summary Report. California's Fourth Climate Change Assessment, p.27. March 12, 2019 Item #7 Page 40 of 43 Attachment "A" to Ordinance No. CS-349 temperatures have increased by more than 1 °Fin many parts of the state, with some areas (including the San Diego region) exceeding 2°F.2 This heating is expected to continue well into the future, with estimates ranging between 4-6°F and 7-9°F by the end of the century.3 T This amendment is justified on the basis of a local topographical condition. Carlsbad has six and a half miles of beaches, three lagoons, several creeks and other low-lying areas prone to flooding. The San Diego Multi-jurisdictional Hazard Mitigation Plan ranks coastal storm, erosion and flooding among the top five hazards for Carlsbad, with potential property loss exposure approaching $200 million dollars.4 There is broad scientific consensus that the earth will continue to warm and that sea levels will rise as a result of thermal expansion of the oceans and increased contributions from melting glaciers. By the end of the century, sea level could rise by 1. 7 to 6.6 feet, inundating beaches and impacting miles of roads and public accesses, the state campgrounds, hundreds of properties, and more than 1,000 acres of environmentally sensitive lands in Carlsbad.5 E This amendment is justified on the basis of local environmental conditions. Sustainability is a core value of the Community Vision, and an intrinsic part of the Carlsbad General Plan. Energy efficiency enhances the public health and welfare by promoting the environmental and economic health of the city through incorporating green practices into the design, construction, maintenance and operation of new and existing buildings. Providing charging infrastructure for electric vehicles will reduce air-pollution and GHG emissions by facilitating increased use of zero emission vehicles. The amendments to the California Green Building Standards Code are reasonably necessary to achieve the following goals of the General Plan Sustainability Element and Carlsbad Climate Action Plan: • Promote energy efficiency and conservation in the community; • Pursue the use of sustainable energy sources; • Reduce the community's greenhouse gas emissions and foster green development patterns; • Maintain a long-term balance among environmental, social and economic concerns, to ensure a vibrant, healthy and prosperous community. The above-listed conditions within the city pose local hazards for which amendments to the California Green Building Standards Code are required. Human activities that release heat-trapping greenhouse gases into the atmosphere (such as through fossil fuel combustion) are the primary driver of climate change.6 Failure to address and 2 Bedsworth, Louise, Dan Cayan, Guido Franco, Leah Fisher, Sonya Ziaja.

Rises in sea level, including in the city's lagoons, could put at risk Carlsbad homes and businesses, public facilities, pub Ii c roads (especially Carlsbad Boulevard) and accessways. According to the Carlsbad Climate Action Plan, community-wide GHG emissions need to be reduced 49 percent by 2035 to help achieve statewide reduction targets necessary to reduce impacts from climate change. Cars and light trucks account for 39 percent of Carlsbad's GHG emissions. Providing electric vehicle charging infrastructure will facilitate increased use of plug-in hybrid and battery electric vehicles, thereby reducing GHG emissions from this sector. For example, the California Air Resources Board estimates that each installed electric vehicle charging station could reduce GHG emissions by 8 to 17 metric tons {CO2 equivalent gases) per year.7 https://www.globalchange.gov/climate-change.
