7.b 1 2016_01_28_CUP supplemental information_v5A WSB Building a legacy—your legacy. Memorandum To: Neil Soltis, City Administrator, City of Scandia Brenda Eklund, Deputy Clerk, City of Scandia Sherri Buss, City Planner, City of Scandia From: Andi Moffatt, WSB & Associates Addison Lewis, WSB & Associates Date: January 28, 2016 Re: Scandia Community Solar Garden CUP WSB Project No. 2619-210 701 Xenia Avenue South Suite 300 Minneapolis, MN 55416 Tel: 763-541-4800 Fax: 763-541-1700 On behalf of Forest Lake Holdco, we would like to address the following items following approval of the requested Conditional Use Permit (CUP) to allow for a community solar garden on Parcel ID 18.032.20.33.0001. Landscaping Plan Condition #2 of Resolution No. 10-20-15-03 required a revised landscaping plan that would provide for screening of approximately 50% of the view of the site from TH 97 and from Manning Avenue. The plan is to include a mix of coniferous and deciduous tree and shrub species and be consistent with Scandia's vegetative requirements and rural character. The revised landscape plan is attached for your review (see Exhibit A). Transformer/Metering Equipment For interconnection purposes, we are requesting to install a transformer box similar to the one shown in the attached picture (see Exhibit 13), approximately 25 feet inside the property line adjacent to the access road in the northeast corner of the site. The installation location is at the request of Xcel and consistent with the utility transformer service locations. Please advise if any permitting or performance standards are required for this type of accessory essential service equipment. Communications Pole Following the approval of our CUP, we were made aware that Xcel Energy will be requiring a wireless communications pole located on the solar garden facility. As such, we would submit that this request be considered under your Essential Services, as the request is at the behest of Equal Opportunity Employer wsbeng.com K:\02619-210\Admin\Docs\CUP submittal\2016_01 28 CUP supplemental information v5.docx January 28, 2016 Page 12 Xcel Energy and is not of any secondary use other than for the health and safety of operations and maintenance by Xcel Energy, similar to other essential services equipment. Our request is to allow for an antenna atop a wooden pole that is to be no higher than 85 feet. The final height will be subject to radio frequency tests to connect the communications equipment from the solar facility to Xcel Energy's substation. The purpose of the pole is solely for Xcel's ability to shut down the solar facility in an emergency, to control power from flowing back into the transmission system, and the maintenance and operations of the electrical transmission distribution system. The proposed pole would be located in the northeast corner of the site, as shown on the attached survey (see Exhibit C), located 1,313 feet from TH 97 and 210 feet from Manning Trail. The proposed pole would be setback 12 feet from the north property line. An example picture of the communications pole is attached (see Exhibit D) and in addition to information provided from Xcel with more detail on the purpose for the communication pole (see Exhibit E). We would also be interested in your comments if Xcel requested us to move the pole at a later time, could we seek administrative approval? Please advise if other information is needed to accommodate this request. Service Roads Condition #10, b. of Resolution No. 10-20-15-03 states that the gravel access road shall be a minimum of 20 feet in width to permit emergency access. A pipeline blanket easement existed on the property in favor of Northern Natural Gas for a pipeline located on the east side of the property. In working with the gas company, a revised easement agreement was developed to establish specific boundaries on the property for the pipeline, as shown on the survey in Exhibit C. The gas company requires an easement of 120 feet in width, which presents a solar panel layout and design challenge. In order to accommodate the pipeline easement and the insure a full 5 megawatt facility as proposed, we are requesting that the required width of the access road be reduced to 16 feet. SolarStone has several projects where this road width has been approved in other jurisdictions. Fencing In order for us to have the ability to finance and insure the solar facility, we would be required to provide a chain link fence around the entire perimeter of the property, which properly secures the site for general liability, equipment security, and human safety. Our request is for an eight foot (8' foot) galvanized chain link fence. The fence location is shown on the attached survey (see Exhibit C). Please provide any comments regarding the proposed fencing and forward any necessary permit applications as applicable. We appreciate your ongoing assistance regarding our community solar garden in the City of Scandia.
