NOW, THEREFORE, BE IT ORDAINED by the Council of the City of San Luis Obispo as follows: SECTION 1. Purpose. It is the purpose and intent of this Ordinance to establish the Clean Energy Choice Program, including standards for new buildings to exceed minimum 2019 Title 24 Part 6 requirements. SECTION 2. Adoption. The 2019 California Building Code, Title 24, Part 6, is hereby adopted by the City of San Luis Obispo with local amendments to be codified under Chapter 15.04 as specified in Exhibit A. The Council hereby adopts the recitals herein as separate and additional findings of fact in support of adoption of the ordinance. Ordinance No. 1684 (2020 Series) Page 3 O 1684 SECTION 3. Severability. If any word, phrase sentence part, section, subsection or other portion of this amendment or any application thereof to any person or circumstance is declared void, unconstitutional, or invalid for any reason, then such word, phrase, sentence, part, sect ion, subsection, or other portion, or the prescribed application thereof, shall be severable, and the remaining provisions of this amendment, and all applications thereof, not having been declared void, unconstitutional or invalid, shall remain in full force and effect.  The City of San Luis Obispo hereby declares that it would have passed this amendment and each section, subsection sentence, clause and phrase of this amendment, irrespective of the fact that any one or more sections, subsection, sentences, clauses or phrases is declared invalid or unconstitutional. SECTION 4 - Findings. The City Council finds that each of the changes or modifications to measures referred to therein are reasonably necessary because of local climatic, geological, or topographical conditions in the area encompassed by the boundaries of the City of San Luis Obispo, and the City Council adopts the following findings in support of local necessity for the changes or modifications: 1. As a city located on the California Central Coast, San Luis Obispo is vulnerable to the effects of sea level rise and resultant flooding within the San Luis Creek watershed, and human activities releasing greenhouse gases into the atmosphere cause increases in worldwide average temperature, which contribute to melting of glaciers and thermal expansion of ocean water – resulting in rising sea levels. 2. San Luis Obispo is already experiencing the repercussions of excessive greenhouse gas emissions as rising sea levels and severe weather events threaten the City’s nearby shoreline and infrastructure and cause significant erosion leading to infrastructure failures including the Mud Creek slide resulting in closure of Highway 1 for repairs, and economic impacts to surrounding communities. 3. San Luis Obispo is situated along a wildland-urban interface and has been identified as a Community at Risk from wildfire and is extremely vulnerable to wildfires and firestorms, and human activities releasing greenhouse gases into the atmosphere cause increases in worldwide average temperature, drought conditions, vegetative fuel, and length of fire seasons- contributing to the likelihood and consequences of fire. 4. The City of San Luis Obispo is situated at the base of a watershed of the Santa Lucia Mountains and flooding of San Luis, Chorro, Stenner, Old Garden, and Brizzolara Creeks results in conditions rendering fire department vehicular traffic unduly burdensome or impossible, as witnessed in major floods that occurred in 1952, 1961, 1969, 1973, 1978, 1982, and 1995. Furthermore, flood conditions described above create the potential for overcoming the ability of the fire department to aid or assist in fire control, evacuations, rescues and other emergency task demands inherent in such situations. The resulting overburdening of fire department personnel may cause a substantial or total lack of protection against fire for the buildings and structures located in the City of San Luis Obispo. The afore-described conditions support the imposition of fire protection requirements greater than those set forth in the California State Building Standards Code and, in particular, support the imposition of more restrictive requirements than set forth in the California Energy Code for the purpose of reducing the City’s contributions to Greenhouse Gas Emissions resulting in a warming climate and related severe weather events. Ordinance No. 1684 (2020 Series) Page 4 O 1684 5. The aforementioned flood and rain events result in conditions wherein stormwater can inundate the wastewater treatment system as witnessed in major floods that occurred in 1952, 1961, 1969, 1973, 1978, 1982, and 1995. Furthermore, rain events and flood conditions described above create a condition referred to as Inflow and Infiltration (I/I) that allow rain and flood waters to flow and/or seep into the wastewater system and overcome the ability of the wastewater collection system and Water Reclamation Facility (WRF) to convey and treat sewage. The resulting overburdening of the wastewater system can result in threats to public health, public and private property and water quality and violations and fines from the State of California, the Environmental Protection Agency (EPA) or others. To the extent that climate change has the potential to make these conditions worse, more restrictive Energy Code requirements to achieve reduced greenhouse gas emissions are necessary. 6. The City of San Luis Obispo is situated near three major faults each capable of generating earthquakes with a magnitude of 7.5. These are the San Andreas to the east of the City, the Nacimiento-Rinconada that crosses Hwy 101 north of the City then parallels the City to the east, and the Hosgri to the West. Other faults of importance are the Huasna and West Huasna to the Southeast of the City, the San Simeon to the Northwest, and the Edna and Edna Extended faults which enter the southern areas of the City. In as much as these faults are included as major California earthquake faults, which are subject to becoming active at any time, the City of San Luis Obispo is particularly vulnerable to devastation should such an earthquake occur. The potential effects include isolating the City of San Luis Obispo from the North and South due to the potential for collapsing of freeway overpasses or a slide on both the Cuesta and Ontario Grades and the potential for horizontal or vertical movement of the Edna fault rendering surface travel across the southern extremities of the city unduly burdensome or impossible. Additional potential situations inherent in such an occurrence include loss of the City's two main water sources (the Salinas and Whale Rock reservoirs), broken natural-gas mains causing structure and other fires, leakage of hazardous materials, the need for rescues from collapsed structures, and the demand for first aid and other medical attention to large numbers of people. As a result, the City is pursuing a policy to discourage additional natural gas extensions and the related, expanded risk of gas leaks and explosions during seismic events for the protection of human life and the preservation of property in the event of such an occurrence. 7. That seasonal climatic conditions during the late summer and fall create numerous serious difficulties in the control and protection against fire situations in the City of San Luis Obispo. The hot, dry weather in combination with Santa Lucia (offshore) winds frequently results in wildland fires in the brush-covered slopes on the Santa Lucia Mountains, San Luis Mountain, and the Irish Hills areas of the City of San Luis Obispo. The aforementioned areas surround the City. When a fire occurs in said areas, such as occurred in 1985 when the Los Pilitas fire burned six days and entered the City and damaged many structures, the entirety of local fire department personnel is required to control, monitor, fight and protect against such fire situations in an effort to protect life and preserve property and watershed land. The same climatic conditions may result in the concurrent occurrence of one or more fires in the more populated areas of the City without adequate fire department personnel to protect against and control such a situation. Therefore, the above-described findings support the imposition of measures Ordinance No. 1684 (2020 Series) Page 5 O 1684 to increase the efficiency of new buildings in the City and reduce Green House Gas emissions from carbon, and support reducing the amount of natural gas distributed and used throughout the City. SECTION 5 CEQA. This ordinance is categorically exempt from CEQA because it is an action taken by a regulatory agency for the purpose of protecting the environment (CEQA Guidelines Section 15308). In addition, this ordinance is exempt from CEQA under the general rule, 15061(b)(3), on the grounds that these standards are more stringent than the State energy standards, there are no reasonably foreseeable adverse impacts, and there is no possibility that the activity in question may have a significant effect on the environment. The following findings are made in support of these determinations: 1. The purpose of the City’s Clean Energy Choice Policy and the implementation of a Reach Code is to reduce the amount of greenhouse gas emissions in the City of San Luis Obispo that are produced from buildings. 2. All electric buildings constructed in the City of San Luis Obispo consistent with the Clean Energy Choice Policy and implementation of a Reach Code will reduce greenhouse gas emissions, improve indoor air quality, and reduce the risk of catastrophic infrastructure failure, including explosions and fires caused by breaks and leaks in the natural gas distribution system as a result of upset conditions due to deferred maintenance or following an earthquake. 3. The Reach Code approval process requires that City determine it is cost effective and that the local standards will require buildings to use no more energy than current statewide. Furthermore, the CEC approval process requires that the City make the findings as part of its approval process. Therefore, the Reach Code standards can only go into effect if they protect the environment by making buildings more efficient and in a cost-effective manner. 4. The City’s Clean Choice Energy Program enables property owners and developers to take advantage of a statewide effort to build a clean, efficient, and reliable grid to serve expanding energy needs across the State of California. 5. The Intergovernmental Panel on Climate Change estimates that global emissions need to be reduced by 45 percent from 2010 levels by 2030, and 100 percent by 2050 to prevent global catastrophe. However, due to the lack of coordinated action or a comprehensive plan to address this threat at a national level, cities and states across the United States must lead the way. SECTION 6. Violations. Violation of the requirements of this Ordinance shall be considered an infraction of the City of San Luis Obispo Municipal Code, punishable by all the sanctions prescribed in Chapter 1.12. SECTION 7. Effective Date. This Ordinance shall be effective as of September 1, 2020. Ordinance No. 1684 (2020 Series) Page 6 O 1684 SECTION 8. A summary of this ordinance, together with the names of Council members voting for and against, shall be published at least five (5) days prior to its final passage, in The New Times, a newspaper published and circulated in this City. This ordinance shall go into effect at the expiration of thirty (30) days after its final passage. INTRODUCED on the 16th day of June 2020, AND FINALLY ADOPTED by the Council of the City of San Luis Obispo on the 7th day of July 2020, on the following vote: AYES: Council Member Christianson, Stewart, Vice Mayor Gomez and Mayor Harmon NOES: None RECUSED: Council Member Pease ____________________________________ Mayor Heidi Harmon ATTEST: ____________________________________ Teresa Purrington City Clerk APPROVED AS TO FORM: ____________________________________ J.

Adoption of Codes and Applicability. 1. The City of San Luis Obispo hereby adopts the 2019 California Code of Regulations, Title 24, Part 6 (California Energy Code) with local amendments as set forth herein. The provisions of such are hereby referred to, adopted, and made a part hereof as if fully set out in this Chapter except as modified hereinafter. These regulations will be known as the City of San Luis Obispo Energy Reach Code and all prior provisions are hereby superseded. 2. The effective date of this ordinance shall be September 1, 2020 and is applicable to new construction buildings including those that are built after a demolition. The amendments contained in 15.04.110 do not apply to Additions, Alterations, or Attached Accessory Dwelling Units. Residential subdivisions in process of permitting or constructing initial public improvements for any phase of a final map recorded prior to January 1, 2020 are exempt, unless compliance is required by an existing Development Agreement. Additional exemptions and exceptions are identified below. 3. Notwithstanding the requirements of this Chapter and the Council's Clean Energy Choice Policy, and other public health and safety hazards associated with natural gas infrastructure, natural gas may be allowed in a building otherwise subject to the requirements of this ordinance if the authority responsible for entitling or permitting the project makes any of the following findings: a. That current limitations of electric power infrastructure in the vicinity of the project site make it impossible to serve the project without significant upgrades, such as to transformers or other distribution equipment, that are outside the scope of the proposed project and would render it economically infeasible. b. The proposed project would result in a de minimis use of natural gas that could be offset, such as through a sequestration project or other proposal directly tied to the development project. c. Consistent with the purpose and intent of these regulations, the authority granting approval to a project may permit the use of natural gas without requiring the additional efficiency requirements or appliance pre-wiring if it is determined to be necessary to serve public health, safety and welfare. B. Amend Section 100.1(b) by adding the following definitions: ALL-ELECTRIC BUILDING is a building that has no natural gas plumbing installed within the building and that uses electricity as the source of energy for all space heating, water heating, cooking appliances, and clothes drying appliances.
