Chapter 13 —Zoning Code, Section 1320—District Provisions, Subsection 1320.05 —Land Use Chart, is hereby amended by replacing the chart in its entirety as follows: 1320.05 Land Use Chart. See attached Attachment "A" for the Land Use Chart with the addition of Solar Energy Systems as an Accessory Use in the R-1, R-2, and R-3 Zoning Districts. SECTION 2. Chapter 13—Zoning Code, Section 1325—General Regulations, Subsection 1325.02—Accessory Uses, is hereby amended by adding a Subdivision 7 as follows: Subd. 7 Solar Energy Systems A Solar energy systems are an accessory use in the R-1 R-2 and R-3 Zoning Districts subject to the following requirements: 1 Height Solar energy systems must meet the following height requirements: a Roof-mounted solar energy systems shall not exceed the maximum allowed building height in any zoning district. b Ground- or pole-mounted solar energy systems shall not exceed 15 feet in height or the height of the principal structure to which it is accessory, whichever is lower, when oriented at maximum tilt. 2 Setback Solar energy systems must meet the accessory structure setback for the zoning district in which the system is located. a Roof-mounted systems: Consistent with the required building setback, the collector surface and mounting devices for roof-mounted solar systems shall not extend beyond the exterior perimeter of the building on which the system is mounted or built. Exterior piping for solar hot water systems shall be allowed to extend beyond the perimeter of the building on a side yard exposure. 225614v1 b. Ground- or pole-mounted solar energy systems are permitted in rear and side vards and may not extend into the required rear or side yard accessory structure setback when oriented at minimum design tilt. 3. Visibility. a. Solar energy systems with mounting devices. i. Roof-mounted systems on pitched roofs shall not have a highest finished pitch steeper than the roof pitch on which the system is mounted, and shall be no higher than 12 inches above the roof. ii. Roof-mounted systems on flat roofs shall be no higher than five feet above the finished roof. b. Solar energy systems using a reflector to enhance solar production shall be prohibited 4. Coverage. Solar energy systems are subject to lot coverage and impervious surface requirements of the underl3jng zoning district. a. Roof-mounted solar energy systems shall be subject to the Building Code to ensure the system meets the wind load standards for the roof and to ensure ready roof access in the event of a fire or other safety occurrence whereby roof access is needed. b. The surface area of ground- or pole-mounted systems shall be factored as part of the maximum lot coverage by structure and shall not exceed the regulations of the underlying zoning district. c. The surface area of ground- or pole-mounted systems shall be treated as impervious coverage as regulated for each zoning district. If the soil under the panel ggay(s) contains vegetative ground cover, the Zoning Administrator may consider allowing additional impervious coverage Allowed impervious coverage may be increased by up to ten percent above maximum lot coverage for the zoning district provided 100 percent of the excess is accounted for by an approved ground- or pole-mounted solar engM system d. Ground- or pole-mounted systems shall be counted as an accessory structure. 5. Plan Approvals. All solar energy systems shall require the issuance of a building permit. a. Applications that meet the requirements of this policy shall be granted zoning approval by the Zoning Administrator. Plan approval by the Zoning Department does not indicate compliance with Building Code or Electric Code. b. A building permit application for a solar energy system shall be accompanied by scaled horizontal and vertical elevation drawings. The drawings must show the location of the system on the building, or on the property for a ground- or pole-mounted system includingthehe propertylines.ines. 1. For all roof-mounted systems other than a flat roof the elevation drawings shall show the highest finished slope of the solar collector and the slope of the finished roof surface on which it is mounted. 2. For flat-roof applications a drawing shall be submitted showing the distance to the roof edge and any pgapets on the building and shall identify the height of the building on the street frontage side,the shortest distance of the system from the street frontage edge of the building and the highest finished height of the solar collector above the finished surface of the roof c. All solar energy systems shall meet approval of local building code officials consistent with the State of Minnesota Building Code and solar thermal systems shall comply with HVAC-related requirements of the Energy d. All solar energy systems shall comply with the Minnesota State Electric Code SECTION 3. This Ordinance shall become effective immediately upon its passage and publication according to law. A Summary of this Ordinance will be published in accordance with state statute. PASSED and ADOPTED this 12th day of February,2024,by the City Council of the City of Arden Hills, Minnesota.
