7. AZ APA Conference September 29, 2011 Solyndra panel close-up- a new kind of solar panel & in the news!!

8. AZ APA Conference September 29, 2011 2011 CREBs/CDP plans

9. AZ APA Conference September 29, 2011 So far so good, but… All of the early solar projects and the CREBs projects were accessory uses to existing buildings, so no zoning issues Zoning official had ruled that commercial solar facilities were generating plants

10. AZ APA Conference September 29, 2011 The Problem-Good land, bad zoning Large plots of unused city land Closed City landfills Zoning of closed landfills: R-1, R-2, SR, RX-1

11. AZ APA Conference September 29, 2011 Why it mattered TEP 2009 RFP for wholesale power looking for sites for large solar farms near distribution lines and close to customers Solar developers looking for land close to transmission lines too City of Tucson Land Use Code only allowed a generating system for the production of energy in Industrial Zones Closed landfills in various other zones, thus not available for solar!!

12. AZ APA Conference September 29, 2011 2010 Land Use Code changes New definition of Renewable Energy Generation (LUC 6.3.12.3) which includes solar, wind, landfill gas, etc Established process for application for solar farms in most zones, with increasing levels of notice and hearing as move from Industrial to Commercial to Residential

13. AZ APA Conference September 29, 2011 2010 Land Use Code changes Basic premise: more public involvement in zones with more potential conflict Industrial zones: Permitted use subject to performance criteria Commercial zones: Limited Notice Procedure (staff review + opportunity for hearing upon request) Residential zones: Full notice and hearing

14. AZ APA Conference September 29, 2011 First case under new code- Plaza del Sol PV Project Ordinance adopted June, 2010 Special Exception Use Zoning sought per revised City Ordinances Zoning Examiner hearing Dec 9, 2010 Zoning Examiner decision Dec 16, 2010 recommending approval Construction started late Dec 2010
