NEW BUSINESS 4.Subject: Update from Public Works staff on Household Hazardous Waste Program Public Works staff Alex Wykoff updated the Commission on the status of household hazardous waste (HHW) disposal for city residents. Since collection at the door ended on December 31, 2018, and there are constraints with having drop-off sites and temporary events, Cupertino residents can dispose of their HHW through the county-wide Household Hazardous Waste Program (the City pays for this for its residents). Commissioners asked if this information was on the City website, and Wykoff said he would check and confirm. Commissioners also asked for clarification on what HHW is and what Recology picks up at the curb. 3.Subject: Presentation from City staff and consultant on Green Stormwater Infrastructure (GSI) and the City's Municipal Regional Permit (MRP) requirement to adopt a long term GSI Plan Jill Bicknell, EOA, Inc. consultant and Assistant Program Manager for Santa Clara Valley Urban Runoff Pollution Prevention Program, gave a presentation on green stormwater infrastructure (GSI) and responded to 08/29/19 5 of 41 2 Commissioners's questions. Commissioners asked about pervious materials, how projects are reviewed for GSI opportunities, the maintenance and outreach needed for GSI, and GSI opportunities in Cupertino. Bicknell will forward her presentation to staff and Cheri Donnelley will send Gilee Corral (Commission Staff Liaison) the link to the appendixes in the Cupertino Green Stormwater Infrastructure Draft Plan. OLD BUSINESS 2.Subject: Sustainability Speaker Series Subcommittee update and planning for Zero Waste event Sustainability Speaker Series Subcommittee members Vice Chair Latshaw and Commissioner Chen met with staff to plan the logistics of the upcoming Bea Johnson/Zero Waste event. This event will take place at Community Hall on Monday, September 23 from 6:30 p.m. to 8 p.m. with doors opening at 6 p.m. There is a marketing plan which includes a flyer and outreach to the high schools. The activity focused on the zero waste concept is a table with information and items to give away. Reusable cups, utensils, and napkins will be used. Foods served will be along the line of finger foods (veggies, fruits). Johnson will be paid electronically and not with a paper check. Commissioner Swaminathan will introduce Bea Johnson. Donnelley will send Johnson's bio to the Commission. Commissioners discussed if Johnson could address how a zero waste lifestyle can co- exist with Marie Kondo's minimalist lifestyle. Donnelley mentioned that questions for Johnson could be sent in advance. NEW BUSINESS 5.Subject: Fall Festival tabling planning Commissioners discussed their availability to table at the 2019 Fall Family Festival.

This page rst lists and discusses the general steps that most local governments will follow to develop and adopt a reach code below, and then sets out a generalized timeline and provides information that local government sta should know about timing here. General Steps 1.Develop idea for a reach code ordinance 2.Work with stakeholders 3.Obtain a cost-e ectiveness study 4.Develop and draft an ordinance 5.Public process and revisions 6.Formal adoption process 7.Application for approval by California Energy Commission Develop idea for a reach code Ideas for reach codes can come from several places. In some cases, local governments may have clear direction from an elected body, from a General Plan policy, or from a Climate Action Plan measure. Even when a reach code idea is not clearly stated, General Plans and Climate Action Plans are good starting places to help identify what kinds of e orts will be most consistent with a jurisdiction’s goals and objectives. Cities and towns may also want to coordinate Home Process for Reach Code Development & Adoption Process for Reach Code Development & Adoption ABOUT EVENTS SERVICES REACH CODES RESOURCES CONTACT 08/29/19 12 of 41 8/23/2019 Process for Reach Code Development & Adoption – BayREN Codes & Standards https://www.bayrencodes.org/reachcodes/process-for-reach-code-development-adoption/#GeneralizedTimeline 2/5 with neighboring jurisdictions’ e orts in order to provide some consistency to help with implementation and enforcement. Model ordinances, if they exist, may be another good resource. Work with stakeholders Engagement with stakeholders is essential throughout the reach code development process. Both internal stakeholders, in terms of other local government sta and o cials, and external stakeholders, such as local developers, need to be considered.Key stakeholders include, but are not limited to: Elected o cials Building O cial and building department sta Any other sta who will be involved in implementing and enforcing the reach code Local developers and contractors Environmental advocacy groups Energy code consultants Obtain a cost e ectiveness study All reach codes must be shown to be cost e ective. To be cost e ective, the money saved from the reduced energy costs needs to be enough to cover the initial cost within a reasonable period of time. Cost e ectiveness is usually demonstrated through a study prepared by a consultant. Local governments can use any study that applies to the climate zone in which the jurisdiction is located (click here to see a map of energy climate zones). All nal approved cost e ectiveness studies are posted on the California Energy Commission (CEC)’s website here. A cost-e ectiveness study can be funded directly by a city, but most studies are developed under the auspices of the Statewide Investor Owned Utilities Codes and Standards Team (Statewide IOU Team) and funded by ratepayer funds. To request a cost e ectiveness study from the Statewide IOU Team, please contact info@LocalEnergyCodes.com. If the Statewide IOU Team cannot accommodate a local government’s request, BayREN may be able to fund a cost-e ectiveness study. Contact codes@bayren.org for more information. Develop and draft an ordinance The cost-e ectiveness study tells what measures may be legally required as part of a reach code, but the reach code ordinance itself still needs to be developed. Ordinances often include information on: The purpose of the reach code What types of buildings and actions trigger the reach code Whether there are any exceptions to or exemptions from reach code requirements Relevant de nitions and interpretations Any additional administrative requirements Developing a reach code ordinance will frequently involve working with the City Attorney, the Chief Building O cial, the Planning Director, and other city sta who may be involved in implementing or enforcing the reach code. Providing opportunities for input from both internal and external stakeholders while developing an ordinance can help to identify and work out potential areas of con ict early, to smooth the public process. In addition, local governments can 08/29/19 13 of 41 8/23/2019 Process for Reach Code Development & Adoption – BayREN Codes & Standards https://www.bayrencodes.org/reachcodes/process-for-reach-code-development-adoption/#GeneralizedTimeline 3/5 ask the California Energy Commission to review a draft ordinance and provide feedback before or at the start of the public process, so that any issues can be resolved before the ordinance is adopted. Public process and revisions Each jurisdiction will have its own public process for a reach code. In some cases, jurisdictions may have sustainability committees or climate task forces to work with, while in other communities the City Council may wish to drive the process. What will be similar across jurisdictions is that at this point, the draft ordinance will become public, often together with a sta report. Local committees, residents, businesses, and other stakeholders will all have the opportunity to review the draft and provide comments and suggest revisions. In some cases, the draft ordinance may be revised and released for a second, or even third, round of comments, until the ordinance is ready for formal action. Formal adoption process Since a reach code is a local ordinance, it is adopted by the City Council, Town Council, or County Board of Supervisors using the usual procedure for local ordinances. This requires public hearings, public notice in advance of the public hearings, and both a rst reading of the ordinance and second reading of the ordinance at a public meeting. Some jurisdictions may include either the rst reading or the second reading of the ordinance on a consent agenda. Approval by and ling with state agencies California Energy Commission (CEC) Once the local reach code is adopted, but before it can be enforced, the ordinance must be submitted to the CEC. The CEC will verify that the reach code is at least as stringent as the California Energy Code and then post the reach code and accept comments on it for 60 days. At the regularly scheduled business meeting closest to the end of the public comment period, the CEC will consider the reach code. CEC sta typically present the application, and Commissioners deliberate and vote. Local government sta do not need to attend this meeting but can work with CEC sta to make arrangements to call in.To submit a reach code to the CEC, a local government should create a ZIP le with the following attachments and email it to Ingrid Neumann at Ingrid.Neumann@energy.ca.gov: Attachment 1: Cover Letter to CEC (click here for a template) Attachment 2: Copy of nal Sta Report Attachment 3: Copy of signed Ordinance Attachment 4: Supplemental documents, such as guides for applicants (this is optional, but helps illustrate the adopted policy) Attachment 5: Copy of cost e ectiveness study used. If multiple, a brief overview of which study was used for which portion of the policy is recommended. Attachment 6: Notice of Exemption (click here for a template) Attachment 7: Letter from Chief Building O cial (click here for a template) California Building Standards Commission (BSC) All reach codes and other amendments to the California Building Standards (California Code of Regulations, Title 24) need to be led with the BSC. One way to do this is to share the following documents in an email to ordinance lings@dgs.ca.gov: 08/29/19 14 of 41 8/23/2019 Process for Reach Code Development & Adoption – BayREN Codes & Standards https://www.bayrencodes.org/reachcodes/process-for-reach-code-development-adoption/#GeneralizedTimeline 4/5 Attachment 1: Cover Letter (click here for a template) Attachment 2: Proof of publication (as required by your jurisdiction) Attachment 3: Copy of nal Sta Report Attachment 4: Copy of signed Ordinance For more information, visit the BSC website. Generalized Timeline The graphic below shows a generalized timeline for development and adoption of a reach code, which is followed by information on some timing issues of which local government sta should be aware. Reach code timing issues Because local energy codes must be more stringent than the statewide code, each local code needs to be re- approved whenever the statewide code is updated. As a result: Adopting a local code to take e ect early in the code cycle will be most e cient. When adopted late in a code cycle, a local reach code may only be in e ect for a few months. If a jurisdiction has a reach code in e ect and would like to continue it into the next code cycle, the local process needs to be completed early enough that it can be approved by the CEC before the start of the new code cycle, usually no later than September in the year before the updated code takes e ect. Three options local governments can consider in terms of timing are: 08/29/19 15 of 41 8/23/2019 Process for Reach Code Development & Adoption – BayREN Codes & Standards https://www.bayrencodes.org/reachcodes/process-for-reach-code-development-adoption/#GeneralizedTimeline 5/5 1.Adopt a reach code at the time the local updated Building Code is adopted. Each jurisdiction adopts the updated California Building Code, together with any local amendments, usually late in the year before the updated code takes e ect. Because a reach code is an amendment of the Building Code, it often makes sense for a jurisdiction to adopt a reach code at the same time as it adopts the Building Code.However, when they are adopted together, the Building Code and the local reach code usually will not take e ect at the same time. This is because the CEC needs to approve the reach code, while no further approval is needed for the Building Code. As a result, the reach code will likely not take e ect for several months after the updated Building Code has been in place. 1.Adopt a reach code to take e ect at the same time as the updated Building Code. Another option is to adopt a local reach code earlier than the rest of the Building Code, so that they can take e ect at the same time. To do this, the reach code generally needs to be adopted no later than September of the year before the updated Building Code takes e ect. This will allow time for the CEC to review the reach code, provide the required 60-day comment period, and hopefully approve it at their December business meeting. In most cases, local adoption of the California Building Code and any other amendments will then need to occur later in the year.This path may be particularly useful for jurisdictions that have a reach code in place that they wish to continue into the new code cycle. 1.Adopt a reach code at some other time, when it makes sense in terms of the local process. Some jurisdictions may not have previously adopted a reach code they want to continue, and may not be ready to adopt a reach code when the updated Building Code is adopted. In this case, the best option may be to plan to adopt once the local process is complete. Suggest additional links for this page by emailing codes@bayren.org. 2019 © BayREN Codes & Standards.

This exemption is in alignment with the existing and proposed 2019 state wide CALGreen multifamily code (Part 11, Chapter 4, section 4.106.4)1. 2)Minor clarification addressing construction documents in the definition of EV Capable; 3)Clarifications in the Good Design Practices sections between Level 1 and Level 2. Definitions: EV Capable: A parking space linked to a listed electrical panel with sufficient capacity to provide at least 110/120 volts and 20 amperes to the parking space. Raceways linking the electrical panel and parking space only need to be installed in spaces that will be inaccessible in the future, either trenched underground or where penetrations to walls, floors, or other partitions would otherwise be required for future installation of branch circuits. Raceways must be at least 1” in diameter and may be sized for multiple circuits as allowed by the California Electrical Code. The panel circuit directory shall identify the overcurrent protective device space(s) reserved for EV charging as “EV CAPABLE.” Construction documents shall indicate future completion of raceway from the panel to the parking space, via the installed inaccessible raceways. Level 1 EV Ready Circuit: A parking space served by a complete electric circuit with a minimum of 110/120 volt, 20-ampere capacity including electrical panel capacity, overprotection device, a minimum 1” diameter raceway that may include multiple circuits as allowed by the California Electrical Code, wiring, and either a) a receptacle labelled “Electric Vehicle Outlet” 1 The model reach code multifamily $4,500 per unit-parking space utility cost exemption is based on extrapolating the CALGreen 2019 exemption (and associated charging infrastructure requirements) to that of the model reach code charging infrastructure requirements. Specifically, the CALGreen 2019 code includes a $400 per dwelling unit exception and an associated 10% EV capable per parking space requirement. The model reach code has a 100% EV ready requirement per dwelling unit parking space (essentially ten times that of the CALGreen code) equating to a $4,000 per impacted parking space. Further, the $4,000 figure was adjusted to $4,500 to more accurately represent construction costs in San Mateo and Santa Clara Counties as compared to the California average (https://lao.ca.gov/reports/2015/finance/housing-costs/housing- costs.aspx). Finally, the exception was also broadened to address any on-site transformer costs. 08/29/19 35 of 41 Electric Vehicle Infrastructure 2019 Reach Code Language CALGreen Format Version Date: 10 July 2019 Update to Original Version Date: 13 June 2019 2 with at least a ½” font adjacent to the parking space, or b) electric vehicle supply equipment (EVSE). Level 2 EV Ready Circuit: A parking space served by a complete electric circuit with 208/240 volt, 40-ampere capacity including electrical panel capacity, overprotection device, a minimum 1” diameter raceway that may include multiple circuits as allowed by the California Electrical Code, wiring, and either a) a receptacle labelled “Electric Vehicle Outlet” with at least a ½” font adjacent to the parking space, or b) electric vehicle supply equipment (EVSE) with a minimum output of 30 amperes. Electric Vehicle Charging Station (EVCS): A parking space that includes installation of electric vehicle supply equipment (EVSE) with a minimum output of 30 amperes connected to a Level 2 EV Ready Circuit. EVCS installation may be used to satisfy a Level 2 EV Ready Circuit requirement. SECTION 4 RESIDENTIAL MANDATORY MEASURES 4.106.4 Electric vehicle (EV) charging for new construction.
