      (3)   An interconnection agreement must be completed with the electric utility in whose service territory the system is located.
      (4)   All structures must comply with setback, height and coverage limitations for the district in which the system is located.
      (5)   Ground-mount systems must comply with all required standards for structures in the district in which the system is located.
   (B)   Solar farms.
      (1)   General provisions.
         (a)   Solar farms are only allowed in the Industrial Districts.
         (b)   Solar farms require a conditional use permit.
         (c)   Solar farms are subject to the city’s stormwater management and erosion and sediment control provisions and National Pollutant Discharge Elimination System (NPDES) permit requirements.

For solar farms located within 500 feet of an airport or within the A or B safety zones of an airport, the applicant must complete and provide the results of the Solar Glare Hazard Analysis Tool (SGHAT) for the Airport Traffic Control Tower cab and final approach paths, consistent with the Interim Policy, FAA Review of Solar Energy Projects on Federally Obligated Airports, or most recent version adopted by the FAA.
      (6)   Agricultural protection. Solar farms must comply with site assessment or soil identification standards that are intended to protect agricultural soils.
      (7)   Proper maintenance. All solar installations shall be maintained according to industry standards and shall be in working order for the duration of its useful life.
