Item 6C - Solar Energy Ordinance Staff ReportITEM 6C M E M O R A N D U M February 9, 2021 TO: Southlake City Council FROM: Kenneth Baker, Sr. Director of Planning and Development Services SUBJECT: Ordinance 480-DDDDD, 2nd Reading, Amendments to Zoning Ordinance 480, to allow the administrative approval of Solar Energy Systems (Solar Panels) meeting certain design and location criteria. The purpose of this item is for the City Council to conduct a public hearing and consider 2nd reading approval of amendments to the City’s Zoning Ordinance 480 that will allow the administrative approval by the City’s Planning and Development Services Department of solar energy systems (solar panels) meeting certain design and location criteria. The City of Southlake currently requires the approval of a Specific Use Permit (SUP) for the installation of all solar energy systems (solar photovoltaic - PV) installations for both commercial and residential properties. Contained in this report are regulation options to consider for inclusion in Section 34 of the City’s Zoning Ordinance-Accessory Use. Also presented in this report are modifications to Section 45-Specific Use Permits of the City’s Zoning Ordinance to reflect modifications in section 34 of the ordinance. Background The price of solar energy systems has declined in recent years, with the average installed cost for residential solar photovoltaics (PV) dropping significantly. Most of this decline has come from falling equipment prices, with the non-equipment costs, also known as soft costs, remaining fairly consistent. On the following page is a graph that illustrates the general cost over time of installing solar panels. The efficiency of the solar systems continues to improve and the cost recovery time on a system continues to be reduced. It is expected that as a result of increasing electrical costs in the region due to population and development demands and improve efficiencies regarding cost recovery times on solar systems, the demand for solar systems for both residential and commercial will increase. Solar Panel Cost Over Time Source: Energysage As mentioned previously, the City’s current regulations require the approval on a SUP for the installation of all energy solar systems. On average it takes approximately 2.5 months to process a Specific Use Permit application for a residential solar system (Time from the application submission to the PDS department to City Council approval). In 2020, the City Council approved five (5) SUP applications for solar systems and in 2019, the City also approved five (5) applications. To date in 2021, City Council has approved two (2) SUP applications for solar energy. The number of SUP applications are expected to increase as the efficiency of the solar energy systems improve. The current SUP solar energy system zoning ordinance requirements are as follows (section 45.1.44): ******************************************************************************************************* Specific Use permit type Zoning Dis trict Allowed Section 45.16 SPECIFIC REGULATIONS FOR SOLAR ENERGY SYSTEMS (As amended by Ordinance No. 480-WWW) The purpose of this section is to establish standards for Solar Energy Systems.

No solar energy system shall be constructed upon a lot until a building permit has been issued or principal use has actually been commenced. b. A line of sight analysis will be required in addition to the applicable submittal requirements under Section 40 (Development Plans and Site Plans) of the City of Southlake Zoning Ordinance. ******************************************************************************************************* Below is a list of recent solar energy system approvals the past 3 years: Case/Location # panels Square footage System kilowatts Approval Date ZA20-0062 – Bent Creek Dr. 37 728 (roof) 12.58kW 1/19/21 ZA20-0063 – Water Lily Dr. 20 385 (roof) 6.8kW 1/19/21 ZA20-0051– Lake Carillon Ln. 23 394 (roof) 6.82kW 11/17/20 ZA20-0044 – Fontaine Dr. 23 408 (patio roof) 7.7kW 10/6/20 ZA20-0010 - Saddleback 40 855 (ground) 15kW 4/21/20 ZA19-0082 – Devon Ct. 29 511 (roof) 7.55kW 2/4/20 ZA19-0076 – Kingswood Dr. 45 788 (roof) 13.95kW 1/21/20 ZA 19-0056-Greenbough Ln. 31 555 (roof) 10.1kW 11/5/19 ZA-19-0051-Harbor Court* 116 2,905(roof) 52.65kW 10/15/19 ZA19-0036-Wyndham Hill Ln. 36 643 (roof) 11.5kW 8/20/19 ZA19-0018 Scenic Dr. 46 843 (roof) 14.95kW 6/4/19 ZA19-0012-Lake Carillon Ln. 28 594 (roof) 10.22kW 4/16/19 ZA18-0042 Regal Oaks Dr. 30 525 (roof) 9kW 11/6/18 * Initially submitted and approved under case ZA18-0041 but revised in case ZA19-0051 In the fall of 2020, both the City Council and PZ Commission requested that the staff review the current solar energy regulations for possible modifications to allow staff the ability for administrative approval. In addition, the City’s 2030 Sustainability Plan recommends that the Solar Energy ordinance be modified to allow by right (administrative) approval of sol ar panels under certain circumstances. As such staff has developed some preliminary administrative approval options related to energy system applications for the committee to discuss. Possible amendments to consider: Amendment #1 Residential Zoning Districts - Allow solar energy systems installed on flat roof structures accessory buildings placed on a permanent foundation (i.e. patios, gazebos) to be approved administratively if the following criteria is met: 1) A line of site analysis demonstrates that the system is not visible from any public or private roadway /right of way. 2) The total solar array is less than 600 square feet (cumulative). Example: Panels installed an outdoor patio. Panels installed an outdoor patio. Amendment #2 Residential Zoning Districts - Allow solar energy systems installed on flat roof structures that are an extension or attached (Patio extension) to the main house be approved administratively if the following criteria is met: 1) A line of site analysis demonstrates that the system is not visible from any public or private roadway/right of way. 2) The total solar array is less than 600 square feet (cumulative). Example: Panels installed on an patio. Amendment #3 Non-Residential Zoning Districts - Allow solar energy systems installed on flat roof structures to be approved administratively if the following criteria is met: 1) A line of site analysis demonstrates that the system is not visible from any public or private roadway/right of way or any residential zoned or residentially land use plan property within 300 feet of the structure.

Message to the City Southlake is a beautiful little city and I want to keep it that way. It's really special and the presence of solar panels would not enhance the beauty. I'm voting against general use of solar panels. They have their place, but they can be, and often are, an eyesore when damaged by wind and hail. If they are on the roof of a commercial building and are not visible to the general public then they might be acceptable. Thank you for all you are doing to keep Southlake the beautiful, safe, and friendly city that it is. Denise Willhoit Sent: Tuesday, January 12, 2021 9:12 AM To: Mayor-Int <Mayor-Int@ci.southlake.tx.us>; Mayor and City Council <MayorandCityCouncil@ci.southlake.tx.us; Mayor <Mayor@ci.southlake.tx.us> Subject: Solar Panels Mayor Hill and City Council Members, In regards to yesterdays phone message of Council/Town Hall Meeting regarding Solar Panels we would like to state our thoughts for the record. We do NOT think Southlake should allow any Solar Panels that would be visible to the public, this includes neighbors whose homes are behind or adjacent. It must be kept in mind how fragile Solar Panels are in hail, especially if mounted on flat commercial style roof. Suggestion to conserve on energy use; we would love to have our Town Square business NOT have their doors open in extreme heat and cold temps. Thank you each for your service!
