HomeMy WebLinkAbout3 - Ordinance Amendment - Solar Energy Systems To: Planning Commissioners From: John Hinzman, Community Development Director Date: March 27, 2023 Item: Public Hearing - Amend City Code Chapter 155 – Solar Energy Systems Planning Commission Action Requested Hold a public hearing and recommend action to amend City Code Chapter 155 – Zoning Code establishing requirements for solar energy systems. Purpose The City does not currently have regulations pertaining to installation of solar energy systems. Staff has fielded requests for solar farms and believes regulations are necessary. Solar Energy Systems Solar energy systems collect or store solar energy, transforming it to another form of energy or transfers heat from a collector to another medium. Systems generally include solar panels and related infrastructure necessary for collection and transfer of energy. Types of Systems Planning Commission Memorandum Roof Mounted Wall Mounted General Regulations Solar energy systems would be regulated based on system type as follows: Type Allowable Zoning District Permit Type Performance Standards All Systems under 6 s.f. All Districts No permit needed N\A Wall Mounted All Districts Building Permit Limit visibility to ROW Integrated into building design Comply with minimum setbacks Roof Mounted – Individual Use All Districts Building Permit Flush to roof Angled only if flush not feasible Must meet height requirements Limit view from public ROW Limit glare to neighbors Roof Mounted – Community Solar Garden All Districts on flat roofs Building Permit Flush to roof Angled only if flush not feasible Must meet height requirements Limit view from public ROW Limit glare to neighbors Underground electric connection Decommissioning Plan Ground Mounted – Accessory Use All Districts if property > 5 acres Building Permit Max Height of 15’ Comply with Accessory Setback Prohibited in Front Yard Ground Mounted - Community Solar Garden Agriculture District only > 5 acres Interim Use Permit\Site Plan Minimum 20’setback Screening and buffering Underground electrical connection Stormwater Management Decommissioning Plan Ground Mounted Ground Mounted Solar Farms and Gardens Interim Use Definition The following definition of interim would be added to the definitions section of the zoning code: Interim Use. A temporary use of property until a particular date, until the occurrence of a particular event, or until zoning regulations no longer permit it. Interim Use – Agriculture Zoning District The existing interim use permit language within the zoning code includes only one use – interim waiver of site plan requirements. This has been utilized United Heroes League and Extreme Sandbox to provide for a temporary waiver of Site Plan requirements for a limited period of time. The existing language limiting permits to 18 months has been removed leaving the City the opportunity to structure the length of time based on the individual request. The proposed amendment restructures the existing language and adds provisions for ground mounted community solar gardens and farms. Recommendation Approval of the proposed ordinance is recommended.
