p. 
All development and engineering design shall be in conformance with Section 
1205 of the Maricopa County Zoning Ordinance; Drainage Policies and Standards; 
Floodplain Regulations for Maricopa County; MCDOT Roadway Design Manual; 
and current engineering policies, standards and best practices at the time of 
application for construction.  
 
q. 
As part of the building permit process, a Floodplain Use Permit will need to be 
obtained from the Floodplain Management and Services Division of the Flood 
Control District. 
 
r. 
Development and use of the site shall comply with requirements for fire protection 
measures as deemed necessary by the Arizona Fire & Medical Authority. Prior to

the applicable fire protection agency, and shall provide written confirmation that 
the site will be developed in accordance with their requirements.  
 
s. 
The applicant or his successor shall obtain approval of any development plans 
from the applicable Fire Marshall prior to any construction.  
 
t. 
This Special Use Permit shall expire forty (40) years from the date of approval by 
the Board of Supervisors, or upon expiration of the lease to the applicant, or upon 
termination of the use, whichever occurs first. All of the site improvements shall be 
removed within 90 days of such termination or expiration.  
 
u. 
The applicant shall submit an annual written report from the date of approval by 
the Board of Supervisors. The status report shall be reviewed by staff to determine 
whether the Special Use Permit remains in compliance with the approved 
stipulations including maintenance of drainage facilities.  
 
v.

application in accordance with Maricopa County Zoning Ordinance Article 304.9. 
 
w. 
Noncompliance with the conditions of approval will be treated as a violation in 
accordance 
with 
the 
Maricopa 
County 
Zoning 
Ordinance. 
Further, 
noncompliance of the conditions of approval may be grounds for the Planning 
and Zoning Commission to take action in accordance with Chapter 3 (Conditional 
Zoning).  
 
x. 
If a building permit for the facility has not been issued by May 11,2027, this SUP and 
the related Comprehensive Plan Amendments (CPA200808, CPA2009016,

Page 4 of 4 
Rural-190 and the related land use designations to Open Space and Rural 
respectively. Additionally, in the event of reversion, the Land Management Plan 
associated with CPA200004 shall be implemented. 
 
y. 
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 is 
temporary and allows the property to enjoy uses in excess of those permitted by 
the zoning existing on the date of application, subject to conditions and 
stipulations. In the event of the failure to comply with any condition or stipulation, 
and at the time of expiration of the Special Use Permit, 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 or 
stipulations, or the expiration of the Special Use Permit, 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 or expiration of the Special 
Use Permit. The Special Use Permit enhances the value of the property above its 
value as of the date the Special Use Permit is granted and reverting to the prior 
zoning results in the same value of the property as if the Special Use Permit had 
never been granted. 
 
z. 
Non-compliance with the regulations administered by the Maricopa County 
Environmental 
Services 
Department, 
Maricopa 
County 
Department 
of 
Transportation, 
Drainage 
Review 
Division, 
Planning 
and 
Development 
Department, or the Flood Control District of Maricopa County may be grounds for 
initiating a revocation of this Special Use Permit as set forth in the Maricopa County 
Zoning Ordinance. 
 
aa. 
Prior to any ground disturbance activities and prior to the issuance of any 
construction permits, the developer shall provide assurance in an amount and 
form acceptable to the  Maricopa County Planning & Development Department 
sufficient to restore or stabilize the entire site in the event the project is abandoned, 
expires, or otherwise becomes defunct. Additionally, in the event of reversion, the 
Land Management Plan associated with CPA200004 shall be implemented. 
 
bb. 
Continued compliance with the conditions of approval for Z2009063 as 
applicable.

Case # 
Page 2 of 7 
Project Summary: 
 
1. 
The purpose of this request is to amend condition ‘j’ on the current SUP for Arlington Valley 
Solar Energy, approved with case Z2009063 (as amended by Z2012043 Condition ‘j’, 
Z2013102 condition ‘a’ and Z2016059 condition ‘j’, approved by the Board of Supervisors 
on May 11, 2011. The site consists of approximately 1,429 acres for a Solar Generation 
Facility. The proposed language for condition ‘j’ of the subject case is presented here in 
legislative edit format, but based off currently approved Z2016059 language:  
 
j.  
Dedication of additional rights-of-way to bring the total half-width dedication to 
65’ for 395th Avenue shall occur within six (6) months of approval of this request by 
the Board of Supervisors, and prior to zoning clearance. All such dedication shall 
be in fee and free of all liens and encumbrances. Prior to acceptance of such 
dedication, the applicant shall provide the County an owner’s title insurance 
policy issued to the County, the Maricopa County Department of Transportation 
(MCDOT) environmental checklist and any and all other requirements as set forth 
in the “MCDOT Right-of-Way Dedication Reference Guide”. Until Maricopa 
County has accepted said dedications, all responsibilities, including but not limited 
to maintenance and repair for the property to be dedicated shall be that of the 
applicant. Preservation of a rights-of-way area to bring the total half-width to 65’ 
for 395th Avenue shall be maintained in the project design. 
 
2. 
The 395th Avenue alignment in question is located on property owned by Arizona State 
Land Department. Arlington Valley Solar Energy (AVSE) does not own the property and 
so it cannot dedicate State land to the County. On May 20, 2021, MCDOT approved a 
ROW preservation to satisfy the intention of this condition, consistent with CPA2009016.  
 
3. 
The applicant also requests that condition ‘x’ of case #Z2013102 (as amended by 
Z2013102 condition ‘b’ and Z2016059 condition ‘z’), be modified to extend the deadline 
for building permit acquisition from May 11, 2022 to May 11, 2027. The proposed language 
for condition 'x' of the subject case is presented here in legislative edit format, but based 
off currently approved Z2013102 language: 
 
x.  
If a building permit for the facility has not been issued by May 11,2022 2027, this 
SUP and the related Comprehensive Plan Amendments (CPA200808, CPA2009016, 
CPA200917, and CPA200919) will be scheduled for public hearing by the 
Maricopa County Board of Supervisors, upon recommendation by the Maricopa 
[County] Planning and Zoning Commission, to consider reverting the zoning to 
Rural-190 and the related land use designations to Open Space and Rural 
respectively. Additionally, in the event of reversion, the Land Management Plan 
associated with CPA200004 shall be implemented.

facility. The proposal is in concert with the amended Area Plan. 
 
Public Participation Summary: 
 
8. 
In anticipation of the subject Modification of Conditions, the applicant re-posted the site 
in the same general locations as was the case for the previous SUP case, in addition to 
sending written notification to area stakeholders. Staff will also send notice of the hearing 
to all property owners within 300’ of the property and published legal ad in accordance 
with the MCZO. As of the writing of this report, staff is unaware of any public support or 
opposition to the application. 
 
Outstanding Concerns from Reviewing Agencies: 
 
9. 
N/A. 
 
Staff Analysis: 
 
10. 
The purpose of the request is twofold: to modify language regarding right-of-way 
dedications that have been completed under MCDOT dedication docket 2011-0728435, 
and to extend the Special Use Permit expiration date. Staff supports this request clarifying 
land ownership challenges regarding State Trust Land, and the intent of the original 
condition has been fulfilled by the right-of-way dedication to MCDOT.  The plan to 
develop the site as a solar generation facility is appropriate for an area with planned 
solar generation uses. Furthermore, this type of development will add skilled employment

opportunities that will foster economic development in this part of the County and 
increases renewable energy sources and reduce dependency on fossil fuels.

x. 
If a building permit for the facility has not been issued by May 11,2027, this SUP and

stipulations. In the event of the failure to comply with any condition or stipulation, 
and at the time of expiration of the Special Use Permit, the property shall revert to

held on the date of application due to such revocation or expiration of the Special 
Use Permit. The Special Use Permit enhances the value of the property above its 
value as of the date the Special Use Permit is granted and reverting to the prior

Re:  Arlington Valley Solar Energy - Special Use Permit Case Z2009063 
 
Dear Mr. Banker, 
 
By this letter and the attached Special Use Permit Modification of Conditions Application, 
Arlington Valley Solar Energy, LLC (“AVSE”) hereby requests modifications of Conditions "j" 
and "x" of SUP case number Z2009063, as amended. 
 
Condition “j” 
 
Z2009063 Condition “j” (as amended by Z2012043 Condition “j”, Z2013102 condition “a”, and 
Z2016059 Condition “j”) presently reads: 
 
“j. 
Dedication of additional rights‐of‐way to bring the total half‐width dedication to 65' 
for 395th Avenue shall occur on the earlier of a) May 11, 2022, or b) zoning clearance. All 
such dedications shall be in fee and free of all liens and encumbrances. Prior to acceptance 
of such dedication, the applicant shall provide the County an owner's title insurance policy 
issued to the County, the Maricopa County Department of Transportation (MCDOT) 
environmental checklist and any and all other requirements as set forth in the "MCDOT 
Right‐Of‐Way Dedications Reference Guide". Until Maricopa County has accepted said 
dedication, all responsibilities, including but not limited to maintenance and repair for the 
property to be dedicated shall be that of the applicant.” 
 
The 395th Avenue alignment in question is located on property owned by Arizona State Land 
Department.  AVSE does not own the property and so it cannot dedicate State land to the County.  
On May 20, 2021, MCDOT approved preservation to satisfy the intention of this Condition.  This 
is consistent with CPA200916.  AVSE requests the language of the Z2009063 Condition “j” be 
revised as follows: 
 
“j. 
Preservation of a rights‐of‐way area to bring the total half‐width to 65' for 395th 
Avenue shall be maintained in the project design.”

Condition “x” 
 
Z2009063 Condition “x” (as amended by Z2013102 Condition “b” and Z2016059 Condition “z”) 
presently reads: 
 
“x. 
If a building permit for the facility has not been issued by May 11, 2022, this SUP 
and the related Comprehensive Plan Amendments (CPA200808, CPA200916, 
CPA200917, and CPA200919) will be scheduled for public hearing by the Maricopa 
County Board of Supervisors, upon recommendation by the Maricopa Planning and 
Zoning Commission, to consider reverting the zoning to Rural-190 and the related land use 
designations to Open Space and Rural respectively. Additionally, in the event of the 
reversion, the Land Management Plan associated with CPA200004 shall be implemented.” 
 
An extension is needed to allow for additional time to complete the development of and finalize 
commercial arrangements for the project.  The timing and sizing of phases of construction will be 
determined in response to future customer and market demands that are not precisely defined at 
this time.  Typical construction duration for a phase is about 18 months; having several years to 
build out customer phases is necessary. AVSE requests the language of the Z2009063 Condition 
“x” be revised as follows: 
 
“x. 
If a building permit for the facility has not been issued by May 11, 2027, this SUP 
and the related Comprehensive Plan Amendments (CPA200808, CPA200916, 
CPA200917, and CPA200919) will be scheduled for public hearing by the Maricopa 
County Board of Supervisors, upon recommendation by the Maricopa Planning and 
Zoning Commission, to consider reverting the zoning to Rural-190 and the related land use 
designations to Open Space and Rural respectively. Additionally, in the event of the 
reversion, the Land Management Plan associated with CPA200004 shall be implemented.” 
 
Please let me know if you have any questions or require additional information. 
 
Best regards,

SUBJECT: 
Arlington Valley Solar requests modifications. Z2022015  
 
The Maricopa County Environmental Services Department (MCESD) has reviewed 
documents received from the Maricopa County Planning and Development Department 
for the above referenced project. This project is the revision of stipulations “x” and “j” 
of Special Use Permit (SUP) Z2009063 for the proposed Arlington Valley Solar Energy 
I facility. The proposed AV Solar facility would be located on a 2,450-acre irregularly 
shaped parcel surrounding the Arlington Valley energy facility near Elliot Road and 
379th Avenue, southwest of Wintersburg. The solar technology for the facility has now 
been selected as a photovoltaic (PV) facility. A Comprehensive Plan Amendment 
(CPA200808) had been approved by MCESD on June 25, 2008.  The SUP Z2009063 
was approved by MCESD on December 8, 2010. The proposed revisions have no direct 
impact on water or wastewater infrastructure requirements. The parcel is not located 
in the urbanized unincorporated area and is therefore, not regulated by the Maricopa 
County Stormwater Quality Program. 
 
Based on our review of previous similar submittals for solar energy facilities, the 
number of onsite operating personnel for a PV system is generally very low and should 
not require the creation of a public water system.  Any onsite facilities can use a private 
well and a septic system for sanitary wastewater management.  
 
If the water system meets the criteria as a Public Water System (serving 25 people or 
more for any 60 days in a year), it will have to become a regulated PWS.  It is our 
understanding that the applicant has already contacted Ms. Korissa Entringer, MCESD 
Safe Drinking Water Program Manager at 602-506-6935 for more information on this 
process. If a PWS is required at the facility, the water system (wells, distribution and 
treatment systems) will require construction approvals from MCESD prior to 
construction.  The wells and distribution system will be permitted by the Subdivision 
Infrastructure & Planning Program; contact Wesley Shonerd, PE at 602-506-0376.  (No 
applications have been received as of this date.) 
 
The narrative stated that a pre-packaged treatment unit to meet the potable water 
requirements.  This system will require an Approval to Construct prior to construction 
and operation. In addition, the narrative discusses the need for evaporation ponds for 
any wastewater from the water treatment process.  The evaporation ponds will require 
an Aquifer Protection Permit (which the narrative acknowledges) prior to construction.

MCESD understands that an initial meeting was conducted with ADEQ on October 1, 
2009 regarding the Aquifer Protection Permit requirements.  The water treatment 
system and, perhaps, the evaporation ponds may require permitting through MCESD 
Water and Waste Treatment program; please contact Mr. Dale Bodiya at 602-506-
6670 for more information on permitting requirements. (No applications have been 
received as of this date.) 
 
Based on the above, MCESD raises no concern to this project to the Planning & 
Development Department in Accela Automation on February 14, 2022 and can allow 
the project to proceed at this time subject to the following stipulations: 
 
Stipulations: 
1. Prior to issuance of the first facility building permit, all required 
permits for any required drinking water, sanitary, and industrial 
wastewater permits  by MCESD and ADEQ must be submitted to 
the appropriate agency.   
2. No facility operation can begin prior to the approval of the above 
permits (issuance of an Approval to Construct) and a construction 
approval (Approval of Construction) of the required facilities 
signed by MCESD. 
 
It should be noted that several other Maricopa County agencies must review and 
recommend approval of this project.  Final approval authority rests with the Maricopa 
County Board of Supervisors.
