2011 CREBs/CDP plans


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


The Problem-Good land, bad zoning

• Large plots of unused city land

• Closed City landfillsZoning of closed landfills: R-1, R-2, SR, RX-1


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!!


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


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


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

Plaza Del Sol PV Project

• Project details: 630 kW; single axis trackers

• Meets 20% of mobile home community’s electrical load

• On-line May 2011• Financed with help of

TEP REC purchase and §1603 grant

• Next??
