BACKGROUND In 2004, the Governor signed into law a statute that limited a local agencies ability to deny solar energy systems to facilitate the installation of residential solar energy systems. The statute limited a City's review of solar energy system permits to whether the system would result in adverse impacts upon public health and safety. Although the City's Zoning Code, at the time, provided findings that a solar energy system could not impair views, the City could no longer deny an application based on view impairment, as the State code preempted local codes. On November 18, 2008, the City Council adopted Ordinance No. 481, which amended Title 15 (Building and Construction Code) and Title 17 (Zoning Code) to establish a voluntary Green Building Program and establish specific mandatory "green" practices and development standards. As part of this 2008 code amendment, the City's review process for solar panels was amended to comply with the 2004 State Code noted above. As amended, the City's current 1 rt r ; .' 7gVN ,tj y� CITY OF RANCHO PALOS VERDES MEMORANDUM TO: HONORABLE MAYOR & MEMBERS OF THE CITY COUNCIL FROM: JOEL ROJAS, COMMUNITY DEVELOPMENT DIRECTOR DATE: AUGUST 18, 2015 SUBJECT: ORDINANCE AMENDING SECTION 15.04.070 OF THE RANCHO PALOS VERDES MUNICIPAL CODE RELATING TO EXPEDITED PERMITTING PROCEDURES FOR SMALL RESIDENTIAL ROOFTOP SOLAR ENERGY SYSTEMS AND AMENDING SECTION 17.83.050 OF THE RANCHO PALOS VERDES MUNICIPAL CODE RELATING TO APPLICATION PROCEDURES FOR RENEWABLE ENERGY SYSTEMS REVIEWED: DOUG WILLMORE, CITY MANA, Project Manager: Leza Mikhail, Senior Planner RECOMMENDATION Introduce Ordinance No. , thereby amending Section 15.04.070 of Chapter 15.04 of Title 15 of the Rancho Palos Verdes Municipal Code to provide an expedited, streamlined permitting process for small residential rooftop solar energy systems and amending Section 17.83.050 of Chapter 17.83 of Article VII of Title 17 of the Rancho Palos Verdes Municipal Code relating to application procedures for renewable energy systems. BACKGROUND In 2004, the Governor signed into law a statute that limited a local agencies ability to deny solar energy systems to facilitate the installation of residential solar energy systems. The statute limited a City's review of solar energy system permits to whether the system would result in adverse impacts upon public health and safety. Although the City's Zoning Code, at the time, provided findings that a solar energy system could not impair views, the City could no longer deny an application based on view impairment, as the State code preempted local codes. On November 18, 2008, the City Council adopted Ordinance No. 481, which amended Title 15 (Building and Construction Code) and Title 17 (Zoning Code) to establish a voluntary Green Building Program and establish specific mandatory "green" practices and development standards. As part of this 2008 code amendment, the City's review process for solar panels was amended to comply with the 2004 State Code noted above. As amended, the City's current 1 and allows all solar panels above the height limit provided that the proposed installation will have no adverse impact upon the public health and safety. All solar panel installations require subsequent building permits from the City's Building and Safety Division. On September 21, 2014, Assembly Bill 2188 (Chapter 521, Statutes 201) was signed into law by the Governor, thereby amending the California Solar Rights Act to encourage deployment of solar energy systems by reducing the costs and delays associated with local permitting processes. This new State law requires every city and county to adopt an ordinance that creates an expedited, streamlined permitting process for small residential rooftop solar energy systems, as defined below, on or before September 30, 2015 (Gov't Code § 65850.5(g)(1)). The expedited permitting process is only required for "small residential rooftop solar energy systems" which are defined as systems which meet all of the following requirements (Gov't Code § 65850.50)(3)): • The system is no larger than 10 kilowatts alternating current nameplate rating or 30 kilowatts thermal. • The system conforms to all applicable state fire, structural, electrical, and other building codes as adopted or amended by the city, county, or city and county as well as the electrical safety and performance standards specified in Civil Code Section 714(c)(3). • The system is installed on a single or duplex family dwelling. • The solar panel or module array does not exceed the maximum legal building height as defined by the authority having jurisdiction. Since Assembly Bill 2188 requires changes to the procedures for reviewing small residential rooftop solar energy systems, the City needs to revise its Municipal Code to conform with the new State requirements. Given that the proposed code amendments include revisions to Title 17 (Zoning Code), the Planning Commission was required to review the proposed amended language and forward a recommendation to the City Council for its consideration. As such, on August 11, 2015, the Planning Commission reviewed the proposed code amendment and adopted P.C. Resolution No. 2015-14 (see attachment), thereby recommending that the City Council approve the proposed amended text to the Municipal Code that is before the City Council for its review. DISCUSSION Amendment to Title 17 (Zoning Code) Development Code Section 17.83.050 (Application procedures for renewable energy systems) establishes the current planning review process for solar energy systems. As noted earlier, only roof -mounted solar energy systems above the maximum building height (typically 16'-0") require planning review and approval, and said review is limited to only public health and safety impacts. As a result, since there is no way to deny a roof -mounted solar system based on aesthetics or view impairment issues or concerns, Staff approves every roof -mounted solar system application above 16'-0" without any discretionary review. As such, Staff is recommending that the City's existing Zoning Code be amended to eliminate the need to obtain planning entitlements for all roof -mounted solar systems. This would allow applicants to apply directly to the City's Building and Safety Division for a permit where matters of public health and safety will be addressed. Therefore, Section 17.83.050 is proposed to be amended as follows: 2 17.83.050 - Application procedures for renewable energy systems (photovoltaic and solar water heating). A. This section provides standards and procedures for permitting renewable energy systems, such as photovoltaic (solar panels) and/or solar water heating systems, within all zoning districts. 1. Roof -mounted Renewable Energy Systems. Any roof -mounted renewable energy system may be installed after the applicable building permits have been obtained from the City. Small residential rooftop solar energy systems are governed by Section 15.040.070(8) of the Municipal Code. o Any reef mounted enewabln nneFgy systems, Whinh dG nnf eXGeed the n9a the appliGable building and safe4, peFmits have been obtained from the v'cY' 2. Ground -mounted Energy Systems. Installation of renewable energy systems are permitted in any zoning district through a minor site plan review application, provided that such systems do not encroach into a setback area or exceed twelve feet in height, as measured from existing grade. 3. Renewable Energy Systems on Extreme Slopes. Installation of renewable energy systems are permitted to be constructed on an extreme slope without the need for an extreme slope permit." Amendment to Title 15 (Buildina and Construction Code Given the proposed amendments to Title 17 described above, the City's permit review process for roof -mounted solar energy systems will be limited to review by the City's Building and Safety Division. As such, the State -mandated expedited permitting process will be incorporated into the City's Building and Construction Code (Title 15). A streamlined procedure would be adopted for small residential rooftop solar energy systems. The proposed code amendment will require the City to adopt a checklist of all requirements that an applicant must comply with for a small residential rooftop solar energy system to be eligible for expedited review and post said checklist(s) and required permitting documents (attached) on the City's website. The code amendment will also allow for electronic submittal of the permit application and all associated documents and require and expedited City review. Additionally, the code amendment provides that the Building Official is authorized to administratively approve the small residential solar energy system applications. The proposed ordinance also amends Section 15.040.070(A) by adding a provision that any structure that falls under the definition of "covered occupancies" under California Energy Code 9 IMF MW • • • • . 1 2. Ground -mounted Energy Systems. Installation of renewable energy systems are permitted in any zoning district through a minor site plan review application, provided that such systems do not encroach into a setback area or exceed twelve feet in height, as measured from existing grade. 3. Renewable Energy Systems on Extreme Slopes. Installation of renewable energy systems are permitted to be constructed on an extreme slope without the need for an extreme slope permit." Amendment to Title 15 (Buildina and Construction Code Given the proposed amendments to Title 17 described above, the City's permit review process for roof -mounted solar energy systems will be limited to review by the City's Building and Safety Division. As such, the State -mandated expedited permitting process will be incorporated into the City's Building and Construction Code (Title 15). A streamlined procedure would be adopted for small residential rooftop solar energy systems. The proposed code amendment will require the City to adopt a checklist of all requirements that an applicant must comply with for a small residential rooftop solar energy system to be eligible for expedited review and post said checklist(s) and required permitting documents (attached) on the City's website. The code amendment will also allow for electronic submittal of the permit application and all associated documents and require and expedited City review. Additionally, the code amendment provides that the Building Official is authorized to administratively approve the small residential solar energy system applications. The proposed ordinance also amends Section 15.040.070(A) by adding a provision that any structure that falls under the definition of "covered occupancies" under California Energy Code 9 Section 110.10(a) does not need to comply with the existing Municipal Code requirement that all new homes and major remodels, whereby more than 50 percent of the existing interior and/or exterior walls are removed, shall provide a roof layout plan that illustrates how future installation of a photovoltaic system and/or solar water heating system could be accommodated. Energy Code Section 110.10 establishes mandatory requirements for solar ready buildings and includes as "covered occupancies", single family residences located in subdivisions with ten or more single family residences and where the application for a tentative subdivision map for the residences has been deemed complete on or after January 1, 2014. This code amendment is necessary to ensure that the Municipal Code does not conflict with State law. Therefore, Section 15.04.070 is proposed to be amended as follows: A. Notwithstanding the provisions of Section 15.04.010 (Building Code Adopted) of this chapter, new homes and major remodels, whereby more than 50 percent of the existing interior and/or exterior walls are removed, shall provide a roof layout plan that illustrates how future installation of a photovoltaic system and/or solar water heating system could be accommodated. The property owner shall only be required to provide for the installation of one system. The following requirements for each system are as follows: Photovoltaic Systems. Installation of conduit leading from an exterior south -facing, east - facing or west -facing roof, where a minimum of four hours of direct sunlight is achieved, to a stubbed junction box next to the electrical panel. All exposed conduit shall be capped and provided with adequate flashing. The conduit shall not be located on or in the direction of a north -facing roof. Roof reinforcements shall be addressed at the time of installation. 2. Solar Water Heating System. Installation of three-fourths inch hot and cold copper water pipes from a south -facing, east -facing or west -facing roof, where a minimum of four hours of direct sunlight can be achieved, to an existing water heater/tank. Both ends of the three-fourths inch copper pipes shall be stubbed out and shall not be located on or in the direction of a north -facing roof. All exposed pipes shall be capped and provided with adequate flashing. Roof reinforcements shall be addressed at the time of installation. 3. This paragraph A does not apply to any structure that falls under the definition of covered occupancies under California Energy Code Section 110.10(a) (Mandatory Requirements for Solar Ready Buildings). B. This section provides standards and expedited procedures for permitting small residential rooftop solar energy systems within all zoning districts. A small residential rooftop renewable energy system is defined as: a. A solar energsystem that is no larger than 10 kilowatts alternating current nameplate rating or 30 kilowatts thermal; b. A solar energy system that conforms to all applicable state and county fire, structural, electrical, and other building codes as adopted or amended b the he City and Civil Code Section 714(c)(3); C. A solar energy system that is installed on a single or duplex family dwelling; and El A solar panel or module array that does not exceed the maximum legal building height as defined b the he City, Roof -mounted Renewable Energy Systems a. Any roof -mounted renewable energy systems may be installed after the applicable building permits have been obtained from the City, provided the system does not exceed the maximum building height, as no discretionary zoning approval is necessary: b. A building permit application for any roof mounted renewable energy systems shall be limited to the City's Building Official's review of whether the application meets all applicable health and safes requirements of local, state or federal law. C. The City shall adopt standard plan(s) and checklist(s) of all requirements with which applications for roof -mounted renewable energy systems shall comply with in order for the building permit to be issued. The standard plan(s) and checklist(s) shall substantially conform to recommendations for expedited permitting, including the checklists and standard plans contained in the most current version of the California Solar Permitting Guidebook adopted by the Governor's Office of Planning and Research. The Building Official, or his or her designee, shall prepare the standard plan(s) and checklist(s) in accordance with Government Code section 65850(8)(2). The Building Official, or his or her designee, may amend and update the standard plan(s) and checklist(s) as needed for consistency with state law or to protect the public health and safety. d. All documents required for the submission of a small residential rooftop solar energy system permit application, the standard plan(s), and checklist(s) shall be made available on the publicly accessible City website. Electronic submittal of the required permit application and documents by email, or the internet, shall be available to all small residential rooftop solar energy permit applicants. An applicant's electronic signature shall be accepted on all forms, applications, and other documents in lieu of a wet signature. An application that satisfies the information requirements in the checklist(s) and standard plan(s) shall be deemed complete. If an application is deemed incomplete, a written correction notice detailing all deficiencies in the application and any additional information or documentation required to be eligible for expedited permit issuance shall be sent to the applicant for resubmission. The Building Official shall issue a building permit for any complete application as follows: the same day for over-the-counter applications, within 3 business days for electronic applications, or as soon thereafter as may be practicable. Review of the application shall be limited to the Building Official's review of whether the application meets local, state, and federal health and safety requirements. Any condition imposed on an 5 application shall be designed to mitigate the specific, adverse impact upon health and safety at the lowest possible cost. g. Inspection requests may be submitted by email or the internet. The inspection, conducted by the City, shall be done in a timely manner. The Building Official shall use his or her best efforts to schedule an inspection within one (1) day of a request and provide a two-hour inspection window. If a small residential rooftop solar energy system fails inspection, a subsequent inspection is authorized but need not conform to the requirements of this paragraph q. h. Fees. Fees for permits and inspections associated with this Chapter shall be established by resolution of the Citv Council." ADDITIONAL INFORMATION CEQA Compliance In accordance with the provisions of the California Environmental Quality Act ("CEQA"), Staff has determined that the proposed Municipal Code amendments are exempt from CEQA pursuant to Public Resources Code Section 21080.35 because the Municipal Code amendments will allow for the installation of solar energy systems on the roofs of existing buildings. Additionally, the proposed Municipal Code amendments are exempt from environmental review per CEQA Guidelines under the General Rule (Section 15061(b)(3)) because they provide updates and revisions to existing administrative building permit regulations consistent with California law, specifically Government Code Section 65850.5 and Civil Code Section 714. It can be seen with certainty that the proposed Municipal Code text amendments will have no significant negative effect on the environment because the expedited processing of small residential rooftop renewable energy systems will enable these energy systems to be installed more quickly which will benefit the environment by reducing carbon emissions. CONCLUSION Based on the information described in this Staff Report, Staff recommends that the City Council introduce Ordinance No. _, thereby amending Section 15.04.070 of the City's Building and Construction Code and Section 17.83.050 of the City's Zoning Code would allow rooftop solar panels "by -right" under the Zoning Code and would provide an expedited permitting process for small residential rooftop solar energy systems under the City's Building Code. FISCAL IMPACT Revising the City's Municipal Code (Title 15 and Title 17) to allow solar panels "by -right" under the Zoning Code and an expedited review under the Building and Construction Code will reduce the fees taken in for Minor Site Plan Reviews (subsidized fee of $67.50), however the impact to the City's General Fund will be nominal. Furthermore, allowing solar panels "by -right" will be more business friendly and reduce the burden of permitting on residents. Al • ALTERNATIVES In addition to Staff's recommendation, the following alternatives are available for consideration by the City Council: 1) Direct Staff to revise the amendments proposed in the draft Ordinance and return to the City Council with an amended Ordinance for introduction.
