Administrative correction to the action taken November 1, 2023 
with regard to Sun Pond II Z2023025 (C-44-24-075-X-00) – a 
request for a zone change from Rural-43 to IND-2 IUPD for a 
proposed photovoltaic solar power generation facility

Additional 
Comments: 
The Board approved Z2023025 subject to the recommendation of 
the Planning and Zoning Commission. However, the conditions of 
approval recommended by the Commission were incorrectly listed 
on the published agenda with references to “Sun Pond I” instead of 
“Sun Pond II”.  The correct verbiage for conditions ‘a’, ‘b’ and ‘c’ is 
shown below in legislative-edit: 
 
a. 
Development of the site shall be in substantial conformance with the site plan entitled 
“Sun Pond 12 Solar Project”, consisting of nine full-size sheets, dated July 2023, and 
stamped received July 19, 2023, except as modified by the following conditions. Staff may 
determine slight refinements to remain in substantial conformance with the approved site 
plan.  Minor and major amendments to the site plan will be determined in accordance with 
Chapter 3 of the Maricopa County Zoning Ordinance. 
 
b. 
Development of the site shall be in substantial conformance with the narrative report 
entitled “Sun Pond I II Solar Project”, consisting of 18 pages, dated July 2023, and stamped 
received July 19, 2023, except as modified by the following conditions. 
 
c. 
A Plan of Development is approved subject to a site plan entitled “Sun Pond 12 Solar 
Project” consisting of nine full-size sheets, dated July 2023, and stamped received July 
19, 2023. The Plan of Development may be amended administratively under a separate 
application as long as the amendment complies with the established IUPD development 
standards as approved by the Board of Supervisors. Staff may determine slight

refinements to remain in substantial conformance with the approved site plan.  Minor and 
major amendments to the site plan will be determined in accordance with Chapter 3 of 
the Maricopa County Zoning Ordinance. 
 
The Commission recommended conditions ‘a’ – ‘o’ are shown 
correctly in final format in the Commission Recommendation.

d. 
Prior to the submission of building permits the developer must conduct a Class I Cultural

that will need to be conducted during the development of the site.  
 
g.

access and maintain wildlife connectivity across the project area.  
 
j. 
The IUPD overlay instrument is applied to restrict the use of the site and this IND-2 IUPD 
shall limit the use of the site to a photovoltaic electric generation facility including any 
ancillary uses of the facility.  The IUPD may be amended to entitle additional uses via 
Modification of Condition application to the Planning & Development Department, but will 
require legislative approval by the Board of Supervisors after recommendation of the 
Planning & Zoning Commission.

n. 
Noncompliance with any Maricopa County Regulation shall be grounds for initiating a 
revocation of this Zone Change as set forth in the Maricopa County Zoning Ordinance.  
 
o. 
The granting of this change in use of the property has been at the request of the applicant, 
with the consent of the landowner.  The granting of this approval allows the property to 
enjoy uses in excess of those permitted by the zoning existing on the date of application, 
subject to conditions.  In the event of the failure to comply with any condition, the property 
shall revert to the zoning that existed on the date of application.  It is, therefore, stipulated 
and agreed that either revocation due to the failure to comply with any conditions, does 
not reduce any rights that existed on the date of application to use, divide, sell, or possess 
the property and that there would be no diminution in value of the property from the value 
it held on the date of application due to such revocation of the Zone Change. The Zone 
Change enhances the value of the property above its value as of the date the Zone Change 
is granted and reverting to the prior zoning results in the same value of the property as if 
the Zone Change had never been granted.
