Page 4 of 4
f.
The IND-2 IUPD shall limit the use of the site exclusively to a solar electric generating
facility including ancillary offices and ancillary uses. All other site uses shall require
a Zone Change Major Amendment.
g.
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.
h.
The property owner/s and their successors waive claim for diminution in value if
the County takes action to rescind approval due to noncompliance with
conditions.
i.
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, and at the time of expiration of the Zone Change, 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 the expiration of the Zone Change, 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 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.

Project Summary:
1.
RE Papago LLC is requesting a Zone Change from Rural-43 to IND-2 IUPD with a Plan of
Development for a utility-scale solar development project generating approximately 300
megawatts (MWs) of electricity along with 1,200 megawatt hours (MWhs) of battery
storage. The subject property is designated as a Utilities land use in the Tonopah-Arlington
Area Plan and Maricopa County Vision 2030 Comprehensive Plan following two Major
Comprehensive Plan Amendments approved by the Board of Supervisors on December
11, 2019 and January 20, 2020 respectively.
2.
The site is comprised of approximately 2,806 acres of thirty-six (36) privately owned
parcels. The site is not contiguous as the southern and northern portions of the site are
separated by land owned by the Flood Control District of Maricopa County (FCD). The
applicant submitted applications from the owners authorizing the request for the zone
change. It is anticipated that the parcels will be merged prior to construction
permitting. The applicant is proposing a construction period of 18 to 36 months
beginning in Quarter 3 of 2022. Most properties in the immediate vicinity of the project,
with the exception of the aforementioned land owned by FCD, are privately owned.
3.
Nearly all land used for solar energy projects like this are developed for the large fields
of solar collectors that capture the energy through photovoltaic technology. The
subject site is relatively flat and allows for the development of solar energy with little or
no additional grading. Washes are present on site and the applicant has committed to
avoiding washes in conjunction with agency comments. In addition, the general area
contains significant local electrical infrastructure including power generation facilities
(nuclear, gas, and solar), transmission lines, substations, and switchyards. The project’s
gen-tie line will transmit power from the project’s substation to APS Delaney Substation.
4.
The subject site is currently zoned Rural-43. The applicant is requesting to change the
zone to IND-2 IUPD. The base IND-2 zone and requested zoning standards for the IND-2
IUPD district are listed below:

Z2019121
Page 4 of 11
5.
It should be noted that since the applicant is proposing a site plan (required plan of
development, POD) and although the zone change is a legislative approval, the POD is
administratively approved. Therefore, POD approval is contingent upon prior rezoning
approval.
6.
The applicant is requesting to vary setbacks (rear and side), parking spaces required,
landscaping, sight visibility triangles, site enclosure and screening. The proposed
standards are consistent with other similar utility-scale solar facilities in this area of the
County.
7.
The applicant is requesting to vary the rear and side setbacks to 0’.
8.
The applicant is requesting to waive landscaping in order to preserve existing
landscaping (natural desert vegetation). For screening, the applicant has proposed
chain-link with 1’ of barbed wire fencing in lieu of a 6’ CMU wall abutting rural or
residential zoning. Additionally, the applicant is requesting that site uses be permitted
outside of an enclosed building as the nature of the use (solar panels) requires the use to
be conducted outdoors to generate energy.
9.
The applicant is also requesting to vary required site visibility triangles at all driveways and
intersecting alignments. The MCZO specifies that 25’x25’ sight visibility triangles are to be
provided at the property line where all access points are present and at the corner of
properties with an intersection. Sight visibility triangles are unnecessary at alignments
internal to the site. Additionally, proposed fencing at the intersecting alignments and
driveways will not include slats and thus visibility will not be obstructed. Also, the applicant
requested that there be no parking or loading spaces as no regularly occupied buildings
will be placed on site.

Public Participation Summary:
14.
The applicant complied with the Maricopa County Citizen Review Process with the
required posting of the site and notification by first class mail to adjacent property owners
within 300’ of the subject parcel and interested parties. The applicant submitted a Public
Participation Results Report.
15.
According to the Public Participation Results Report, the applicant received 20 inquiries
from residents and interested parties about the proposed zone change. A majority of
the inquiries were information requests or requests for the applicant to purchase property.
16.
The applicant conducted an open house meeting during the Comprehensive Plan
Amendment public outreach period on August 21, 2019. The applicant elected to not
hold a follow-up meeting for the Zone Change public outreach period as the applicant
felt the prior meeting was sufficient to address concerns. There were 5 citizen attendees
not including staff of the applicant.
17.
The applicant received general questions during door-to-door outreach related to view,
property values, construction impacts, construction noise and the potential for increased
population. The applicant included a summary of their citizen contacts and the manner
in which they responded to those questions.
18.
The Arizona Game and Fish Department submitted standard comments related to
protection of local species such as the burrowing owl to be addressed at the time of
construction permitting.
19.
There is no known opposition or support for the proposed zone change.
Outstanding Concerns from Reviewing Agencies:
20.
N/A
Staff Analysis:
21.
The state and Maricopa County recognize the potential environmental and economic
benefits that solar technology can provide. The RE Papago Solar Photovoltaic Power
and Energy Storage Project will use photovoltaic technology that generates energy from
sun absorption. Photovoltaic technology differs from other models of solar electric
generation that require vast amounts of water to cool the units. In contrast, very little
water is utilized for photovoltaic technology. As a result, this development would not
pose a threat to groundwater depletion.
22.
Staff believes the proposed solar facility is well suited to this rural area, which requires
large amounts of relatively flat land. The majority of the land is flat. Staff agrees with the
applicant that the subject site is suitable due to proximity to electrical transmission lines,
nearby stations and substations, and because the surrounding area is vastly
undeveloped. Staff agrees with the applicant that the project will not detrimentally
affect the visual quality of the area.
Z2019121
Page 9 of 11
23.
The development of solar energy over the past several years in Maricopa County
reinforces the County’s interest in promoting the County as an economic leader for solar
development. Staff believes the RE Papago Solar Photovoltaic Power and Energy
Storage Project would add to this effort in a positive way by providing the potential for
500 temporary construction and operation/maintenance jobs. There may also be a small
number of long-term employment opportunities for County residents.

Z2019121
Page 10 of 11
6.
Drainage review of planning and/or zoning cases is for conceptual design
only and does not represent final design approval nor shall it entitle
applicants to future designs that are not in conformance with Section 1205
of the Maricopa County Zoning Ordinance and the Maricopa County
Drainage Policies and Standards. All development and engineering design
shall be in conformance with Section 1205 of the Maricopa County Zoning
Ordinance and current engineering policies, standards and best practices
at the time of application for construction.
7.
Any disturbance to Special Flood Hazard Areas (floodplains) will require
that a Floodplain Use Permit be issued concurrent with the associated
building permit.
8.
Pads for inverters, other electrical equipment, and any buildings within a
Floodplain must be elevated to the regulatory flood elevation or otherwise
designed to meet the requirements of the Floodplain Use Regulations. All

Z2019121
Page 11 of 11
e.
The Owner or Developer shall address and respond to all recommendations of the
Arizona Game and Fish Department (AZGFD) included in the letter dated May 26,
2021 at the time of construction permitting. The response shall be sent to AZGFD
for review and consideration. The Zoning Inspector and/or their designee shall
review the applicant’s response, and any subsequent comments received from
AZGFD, to determine whether the response issued by the Owner or Developer
addresses AZGFD comments in good faith. Should the Zoning Inspector and/or
their designee decide that the Owner or Developer has not substantially
addressed AZGFD comments in good faith, the Owner or Developer shall be
required to propose and implement alternatives to the recommendations made
by AZGFD.
f.
The IND-2 IUPD shall limit the use of the site exclusively to a solar electric generating
facility including ancillary offices and ancillary uses. All other site uses shall require
a Zone Change Major Amendment.
g.
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.
h.
The property owner/s and their successors waive claim for diminution in value if
the County takes action to rescind approval due to noncompliance with
conditions.
i.
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, and at the time of expiration of the Zone Change, 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 the expiration of the Zone Change, 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 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.

2.0 PURPOSE OF REQUEST
RE Papago LLC, the project applicant, seeks a Zone Change with Overlay from Maricopa County to construct,
operate, maintain, and eventually decommission a solar photovoltaic (PV) electricity-generating and energy
storage facility and associated infrastructure collectively referred to as the RE Papago Photovoltaic Solar Energy
Generation and Storage Project (project). The project as proposed would generate 300 megawatts (MW) of
alternating current (AC) electricity and up to 1,200 megawatt-hours (MWh) of energy storage on approximately
2,805.23 acres of privately owned land currently zoned as “RURAL-43” (Rural Zoning District—One Acre Per
Dwelling Unit) in unincorporated Maricopa County, requiring a Zone Change with Overlay to change the zoning
designation to IND-2 with an Industrial Unit Plan of Development (IUPD).
3.0 DESCRIPTION OF PROPOSAL
3.1
Overview
The proposed project would consist of the following development activities:
x
Site preparation, including mowing/removal of vegetation and grading (as necessary)
x
Installation of PV solar arrays, including approximately 1,396,000 PV modules, and steel support
structures, transformers, and up to 93 electrical inverters
x
Installation of approximately 19,000 feet of both underground and overhead 34.5-kilovolt (kV) electric
collection lines to connect the two non-contiguous parts of the project site, as well as to connect parts
of the site to the project substation
x
Construction of one electrical substation and appurtenant equipment in the southeast portion of the site
as shown on Sheet C3.2 of the Site Plan
x
Construction of a 500-kV generation intertie electric transmission line (gen-tie line) less than 0.3 mile
in length consisting of metal transmission towers, conductors, insulators, optical fiber cables, and safety
equipment which would connect (“tie-in”) to Arizona Public Service’s existing Delaney Substation
adjacent to the project site to bring solar-generated power to the nearby regional electricity grid
x
Installation of an energy storage system at size up to 1,200 MWh, consisting of battery or flywheel
enclosures and electrical cabling and appurtenant equipment. If batteries are selected, up to 360 battery
containers would be installed
x
Construction of temporary and permanent project site perimeter fencing and access gates
x
Construction of temporary and permanent on-site access roads for construction and maintenance
activities
x
Construction of other necessary infrastructure, including one permanent operation and maintenance
(O&M) building, a supervisory control and data acquisition (SCADA) system, and a meteorological
data system
3.2
Proposed Uses
The project would be constructed to provide clean and efficient renewable energy to the regional electric grid.
The project would generate up to 300 MW of AC electricity, and up to 1,200 MWh of energy storage. The project
is compatible with nearby land uses as it is located adjacent to the Delaney Substation, multiple existing high
voltage electric utility lines, as well as the likely corridor for the future Ten West Link high-voltage electric
transmission line, proposed to be in service by 2021. Electricity produced from this project would provide clean
energy for up to approximately 57,000 homes.

3.3
Hours of Operations
Once operational, project solar generation would occur during daylight hours. During the longest days of the year,
this would be from 5:30 am to 8:00 pm. With an energy storage system, stored electricity would also be
transmitted to the grid at other times when needed. O&M activities would occur during the lifetime of the project
and would include occasional cleaning of PV modules and replacement/repair of project equipment and
components as needed. These activities would typically occur during normal daytime business hours between
7:00 am and 5:00 pm.
3.4
Project Components
Below is a description of the individual project components.
3.4.1
Preconstruction Activities and Site Preparation
Preconstruction activities include surveying and staking for various project features such as driveways, array
blocks, utility trenches, equipment pads, and support structures. Temporary work areas would also be laid out.
Site preparation activities that occur prior to general construction include site clearing and grading, preparation
of construction staging areas, and construction of the main internal driveways.
3.4.1.1
Clearing and Grading
Prior to construction, the site would be cleared of vegetation and graded and compacted to the minimum extent
needed. Site clearing and soil preparation would occur incrementally and would not commence until the area is
needed for construction or equipment access. Vegetative cover would be retained for as long as possible, with
overall ground disturbance minimized to the maximum extent practicable.
Large areas of the site would undergo grading for the installation of drainage basins and related structures. Final
grades would be designed to provide for positive drainage, as described in On-site Drainage Areas below (3.4.14).
3.4.1.2
Construction Staging Areas
One or two main staging areas would be located within the site footprint and would likely be located in the
northwest or southwest portions of the site. The staging area or areas would be used for construction offices, worker
parking, a first-aid station, material and equipment storage and assembly, and a parking area for vehicles and
equipment. Additional staging areas may be located throughout the site for temporary material storage and
assembly during construction. The staging areas would encompass up to 10 acres and would be secured with an
8-foot-high fence. As needed, temporary power would be provided via mobile generators or local distribution lines.
3.4.1.3
Temporary Roads and Driveways
Temporary roads and driveways would be installed for use during construction; some of these roads and
driveways would be established as permanent features prior to the start of project operation. Temporary driveway
aprons to points of ingress/egress during construction may be up to 80 feet wide to accommodate construction
traffic.
3.4.2
Permanent Project Site Entrances and Internal Roads
The project’s on-site circulation would include project entrances and internal roads. Roads would be compacted,
may include gravel or equivalent, and would be designed according to Maricopa County standards, rules, and
guidance. Road construction would typically proceed as follows: the ground would be grubbed (cleared of
vegetation), scarified (loosened), moisture conditioned, compacted, and graded with a crown in the center.
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative

Several agricultural canals cross the project site. During construction and operation of the solar facility, the bed
and banks of the canals would be completely avoided and would remain outside of the project site fences.
All roads would be constructed to be consistent with facility maintenance requirements and Maricopa County’s
Rural Metro Fire Department (RMFD) standards, the standards of the Harquahala Fire District (HFD), and/or any
other applicable standards.
Any required road improvements would be developed in coordination with the Maricopa County Department of
Transportation (MCDOT) and would be subject to MCDOT requirements, as well as all applicable requirements
of the Maricopa County Air Quality Department, the Maricopa County Flood Control District (FCD), and the
Maricopa County Planning and Development Department.
3.4.3
PV Modules and Support System
Most of the project site would be occupied by solar PV modules and support structures. The ultimate decision for
the module types and racking systems would depend on market conditions and environmental factors. Solar
thermal technology is not being considered.
Types of modules that may be installed include crystalline silicon (abbreviated as c-Si), amorphous silicon
(abbreviated as a-Si), thin-film (including cadmium telluride [abbreviated as CdTe or “cad tel”] and copper indium
gallium diselenide technologies [abbreviated as CIGS]), or any other commercially available PV technology.
Module mounting systems that may be installed are likely to include tracking technology but could be fixed tilt
depending on the PV modules ultimately selected. Multiple types of modules and racking systems may be installed
across the site.
The PV modules would be manufactured at an off-site location and transported to the project site. Module faces
would be minimally reflective, dark in color, and highly absorptive.
Modules would be arranged on-site in long strings called rows. For single-axis tracking systems, the length of each
row of modules would be approximately 300 feet along the north/south axis. For fixed-tilt systems, a row consists
of multiple tables (4 modules high by 10 modules wide, depending on design), each table approximately 65 feet
along the east/west axis, with 1-foot spacing between each table. Spacing between each row would be a minimum
of 14 feet. The solar module arrays would generate electricity directly from sunlight, and electricity would be
collected to a single point at the project substation.
Structures supporting the PV modules would consist of steel piles (e.g., cylindrical pipes, H-beams, or similar).
Tracking arrays would be oriented along a north-south axis, with modules tracking east to west to follow the
movement of the sun. Fixed-tilt arrays would be oriented along an east-west axis, with modules facing generally
south. The total height of the module system measured from ground surface would be up to 12 feet. For fixed-tilt
systems, the modules would be fixed at an approximate 20- to 60-degree angle or as otherwise determined
necessary during final project design. Details in Sheet C3.0 of the Site Plan show typical elevation drawings of
solar panels and tracking systems.
Where excavations are required, the majority of proposed construction activities would be limited to less than 6
feet in depth; however, some excavations, such as those undertaken for the installation of electricity collection
poles and dead-end structures, may reach depths of 20 feet or more.
3.4.3.1
Solar PV System Installation
Prior to the installation of solar arrays, the perimeter of each project area would be securely fenced and gated to
prevent unauthorized access. Perimeter fencing would consist of 6-foot-high chain-link galvanized metal fence
topped by 3 strands of barbed wire approximately 1 foot high. Fence posts would be spaced approximately 10
feet apart, drilled and grouted or driven pneumatically into the soil profile up to an estimated 5 feet deep.
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative
page 5
Construction of the solar arrays would begin with installation of the steel piles (e.g., cylindrical pipes, H-beams,
or similar), which would be driven into the soil using pneumatic techniques, similar to a hydraulic rock hammer
attachment on the boom of a rubber-tired backhoe excavator. The piles would typically be spaced 10 feet apart.
For a single-axis tracking system, piles typically would be installed to a reveal height of approximately 4 feet
above grade, while for a fixed-tilt system the reveal height would vary based on the racking configuration specified
in the final design. For some single-axis tracking systems and for all fixed- tilt systems, a galvanized metal racking
system, which secures the PV modules to the installed foundations, would then be field-assembled and attached
according to the manufacturer’s guidelines.
Modules would be electrically connected into module strings using wiring secured to the module racking system.
Underground cables, either rated for direct bury or installed inside a polyvinyl chloride (PVC) conduit, would
convey the DC electricity from the modules via combiner boxes located throughout the PV arrays to inverters to
convert the DC power to AC. The output voltage of the inverters would be stepped up to 34.5 kV, the collection
system voltage, via transformers located in close proximity to the inverters.
3.4.4
Electric (34.5-kV) Collection Lines
The 34.5-kV collection cables would be buried underground or installed overhead on wood poles typically 50 feet
tall and up to 70 feet tall at up to 250-foot intervals. Pole diameters would typically be 12 to 14 inches.
Underground collection line cables to connect arrays would be installed using ordinary trenching techniques,
which typically include a rubber-tired backhoe excavator or trencher. Wire depths would be in accordance with
local, state, and federal requirements and would likely be buried at a minimum of 18 inches below grade by
excavating a trench approximately 3 to 6 feet wide to accommodate the conduits or direct buried cables. After
excavation, cable rated for direct burial or cables installed inside a PVC conduit would be installed in the trench,
and the excavated soil would likely be used to fill the trench and lightly compressed. All cabling excavations
would be to a maximum depth of 10 feet.
If parcels comprising the project site are not located contiguous to one another, the applicant will secure easements
on adjacent land (outside of the public right-of-way [ROW]) for the installation of collection lines as needed. The
applicant intends to apply for an easement and ROW permit to accommodate 34.5-kV collection lines across
property owned by the FCD of Maricopa County in order to connect two non-contiguous areas of the project site.
Final design will be determined upon detailed engineering and consultation with the FCD, but the collection lines
are preliminarily anticipated to consist of two (2) parallel double-circuit pole lines. Each set of poles would hold
two circuits consisting of three vertically stacked 34.5-kV cables on each side of the pole, along with one grounding
wire along the top of the poles. The poles are anticipated to have a height of between 65 and 80 feet depending
upon clearances required by the FCD as the lines cross the Saddleback Flood Retarding Structure.
3.4.5
Inverters and Transformers
The project would be designed and laid out in approximately 2-MW increments, which would include an inverter
equipment area measuring either approximately 40 feet by 25 feet (in the event that the energy storage system is
AC coupled) or approximately twice this size (in the event that the energy storage system is DC coupled). Up to
93 inverters would be installed. Each 2-MW increment would include an inverter-transformer station constructed
on a concrete pad or steel skid and centrally located within the PV arrays. Each inverter-transformer station would
contain a DC combiner (which would collect DC electrical power from the PV modules), up to 4 inverters, a
transformer, an auxiliary power transformer, an energy storage enclosure (in the event of DC-coupled energy
storage), and a switchboard approximately 8 to 11 feet high. Refer to Sheet C3.4 of the Site Plan for a typical
inverter-transformer station.
All electrical inverters and transformers would be placed on concrete foundation structures or steel skids. In lieu
of steel skids or pre-cast concrete foundations, foundations for the transformer and inverter locations would be
formed with plywood and reinforced with structural rebar and would use poured-in-place concrete.
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative

3.4.6
Project Substation and Gen-tie
The project would also include one electrical substation, which would receive electricity from consolidated
medium-voltage cables from the collection system and step the voltage up to 500 kV via one or two high voltage
transformer banks consisting of up to four individual transformers as well as switchgear and related substation
facilities. The substation area would include an electrical control building. A conceptual elevation of the control
building enclosure is shown in Sheet C3.2 of the Site Plan. The substation would be located in the southeastern
portion of the site near the Delaney substation, as shown on Sheet C2.8.
The project’s generator intertie electric transmission line or “gen-tie” would then transmit the power at a voltage
of 500 kV from the project substation to the project point of interconnection at Delaney Substation. The gen-tie
would be supported by up to four high-voltage support structures consisting of a combination of A-frame dead-
end structures and either H-frames, monopoles, or three-poles. The number of support structures would be kept
to the minimum needed based on potential engineering constraints. The preferred gen-tie route would run straight
east-west, but there is a possibility that a turning structure could be required. The support structures are anticipated
to be approximately 126 feet in height but not more than 140 feet in height, as shown on Sheet C3.5. The design
and height of the support structures would be refined as building permit applications are completed. Because
support structures up to 140 feet in height would be required due to electrical design considerations, the applicant
is also seeking a variance to the County’s requirements that structures to support electric transmission lines
observe a maximum height of 120 feet (Article 1111.7 of the Maricopa County Zoning Ordinance). This variance
is reflected in the proposed Plan of Development for the project, as described in Table 3 (RE Papago Solar Project
Unit Plan of Development: Proposed Zoning Regulations) at the end of this Narrative. The applicant also plans
to submit an application to the Arizona Corporation Commission for a Certificate of Environmental Compatibility
(CEC) for the proposed gen-tie line and project substation.
Telecommunications infrastructure at the project substation would include the installation of an antenna and may
include the installation of a telecommunications tower up to 100 feet high.
3.4.6.1 Installation of Substation and Gen-Tie
The substation area would be graded and compacted to an approximately level grade. Concrete pads would be
constructed on site as foundations for substation equipment, and the remaining area would be graveled to a
maximum depth of approximately six inches. The substation would be surrounded by an up-to 8-foot- high chain
link fence topped with one foot of barbed wire.
For the gen-tie connection, overhead structure foundations would be installed by excavating foundation holes to
a depth of approximately 35 feet using a truck-mounted drill rig. The size of the footprint for construction of the
pole foundation would be approximately 100 square feet. Poles/support structures would be delivered on a flat-bed
trailer and hoisted into place by a crane. The annular space between poles and holes would be backfilled with
concrete or soil. Conductors would be strung between poles with heavy-duty trucks.
3.4.7
Energy Storage System
The project could include, at the applicant’s option, a battery or flywheel storage system capable of storing up to
1,200 MWh of electricity and conducting energy to the regional electricity grid. The storage system would consist
of battery or flywheel banks housed in electrical enclosures and buried electrical conduit. The project would use
commercially available energy storage technology. Options could include but would not be limited to lithium-ion
(Li-ion) batteries, flow batteries, sodium sulfur, or mechanical fly wheels. Battery systems are operationally silent
(except for noise that could be generated by heating, ventilation, and air conditioning [HVAC] systems that may
be required), and flywheel systems have a noise rating of 45 A-weighted decibels (dBA). Standard HVAC systems
have a noise rating ranging from 60 to 68 dBA.
The energy storage system would either be dispersed throughout the project site, connected to the PV array via DC
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative
page 7
(DC coupled), or concentrated in one location on the site, connected to the PV array via AC (AC coupled).
Whether a DC-coupled system or an AC-coupled system is chosen for installation will depend on market
conditions and the availability of commercial options.
For a DC-coupled system, energy storage containers and a DC to DC converter/optimizer would be co-located at
the inverter equipment areas throughout the site. These containers would include an HVAC system and
monitoring, controls, and operational management systems that will maintain normal battery operation and
provide alerts in the case of malfunction.
For an AC-coupled system, the same energy storage containers with related equipment (minus the DC to DC
converter/optimizer) would be grouped together in one area on the site. The energy storage system would not be
housed in a building. Refer to Sheet C3.1 of the Site Plan for conceptual battery storage and inverter details.
Figure 2 shows the conceptual renderings of the potential appearance of a centralized (AC-coupled) battery
storage system.
Figure 2. Artistic rendering of the AC-coupled/centralized energy storage system option.
The energy storage system monitoring, controls, and operational management systems would connect to the
overall solar facility management system and use sensors to monitor the performance of the energy storage
system, detect malfunctions or conditions requiring maintenance, and provide plant operators with notification of
these conditions in real time. The containers will include fire suppression systems, as necessary, for Li-ion battery
systems. Flow battery containers would include secondary containment, as necessary, for circulating fluid
systems.
Energy from the storage system would be conducted to the grid through the PV system inverters in the case of a
DC-coupled system or directly to the grid from the storage system in the case of an AC-coupled system. With the
use of bi-directional inverters with electricity backflow preventers, both DC-coupled and AC-coupled energy
storage systems could also be charged by the electrical grid (as well as being charged by the PV modules) and
therefore provide grid support.
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative

3.4.7.1 Energy Storage System Installation
Construction of the energy storage systems would include 1) site preparation; 2) installation of the foundations,
structures, and systems; and 3) installation of the inverters, substation, and connection.
If the energy storage system is DC-coupled, the energy storage equipment would be co-located at the inverter and
transformer equipment areas within the individual array blocks throughout the site. Site preparation would likely
occur during installation of the inverter and transformer equipment areas. Each energy storage equipment area
would include battery enclosures on concrete foundations.
For an AC-coupled system, the energy storage equipment, including battery storage containers on concrete
foundations, power conversion equipment, and electrical collection, would be concentrated in a single location
most likely near the project substation. The total area of an AC-coupled system would be less than 17 acres. The
site would be cleared and graded prior to installation. The energy storage system would be largely assembled off-
site and delivered to the project site for final installation. Heavy trucks and other equipment would be used to
deliver and install the infrastructure and battery or flywheel enclosures. After a system is installed, it would be
tested and commissioned.
The energy storage system may be installed during installation of the PV arrays, or it could be installed later while
the facility is in operation.
3.4.8
Construction Schedule and Workforce
Construction of the various project components discussed above could occur simultaneously, sequentially, or
some combination thereof. Construction of the project would commence as early as Quarter 3 (Q3) of 2022.
Active construction is anticipated to last approximately 18 months, with the total construction duration potentially
taking place over the course of up to 36 months. Construction is anticipated to be undertaken in phases that may
overlap one another, including an initial site preparation phase, a phase during which the PV modules and energy
storage system would be installed, and a final phase during which the inverters, transformers, substation and
electrical collection system would be installed. The anticipated construction processes, schedule, and workforce
are further described in this section.
The majority of the labor force is expected to come from the surrounding communities with an average round-
trip commute of 130 miles, and a maximum round-trip commute of up to 170 miles. All workers are expected to
come from within Phoenix’s metropolitan area. There would be an estimated workforce of 240 to 500 full-time
employees during construction.
Construction equipment would generally operate between the hours of 7:00 a.m. and 7:00 p.m., Monday through
Friday, for up to a maximum of eight hours per piece of equipment, daily. Weekend construction work is not
expected to be required, but may occur on occasion, depending on schedule considerations.
However, to meet schedule demands, it may be necessary to work early morning, evening, or nights and on
weekends during certain construction phases. Varying work hours can also improve the work environment by
allowing work to be completed during more favorable temperatures. For safety reasons, certain construction tasks,
including final electrical terminations, may be performed after dark when no electricity is being produced by the
PV modules. All construction work, including any weekend work, would comply with the policies and
requirements established by Maricopa County, including the Maricopa County Noise Ordinance.
3.4.9
Construction Access, Equipment, and Traffic
Access to the eastern part of the project site would be provided via I-10 (Exit 94), West Salome Highway, and
West Indian School Road. Access to the western part of the project site would be provided via the same exit from
I-10, West Salome Highway, West Courthouse Road, 491st Avenue, and other numbered streets in the area of the
RE Papago Photovoltaic Solar Energy Generation and Storage Project

parcels.
All materials for the project’s construction would be delivered by truck. The majority of truck traffic would occur
on designated truck routes and major streets. Flatbed trailers and trucks would be used to transport construction
equipment and materials to the site. Project components would be assembled on-site. Traffic resulting from
construction activities would be temporary and could occur as workers and materials are transported to and from
the project site. Materials deliveries during construction would travel up to 85 miles one way from the source to
the project site.
Anticipated daily peak-hour vehicle trip volumes and equipment to be used for each construction phase are
presented in the Traffic Impact Study included as part of this application. Typical equipment will include pickup
trucks, bulldozers, water trucks, and gravel trucks. Any required road improvements for construction activities
would be developed in coordination with MCDOT and would be subject to MCDOT requirements, as well as all
applicable requirements of the Maricopa County Air Quality Department, the Maricopa County FCD, and the
Maricopa County Planning and Development Department.
3.4.10 Personnel Training
3.4.10.1
Biological Resources
Prior to construction, a qualified biologist would be retained by the project applicant or construction contractor
to conduct environmental awareness training for project construction personnel. Such training would
communicate information related to the protection of sensitive biological resources that might be present at the
project site and would include:
x
A description of species of concern and associated habitats
x
The general provisions of applicable environmental regulations and the need to adhere to the
provisions of the regulations
x
General measures being implemented to conserve the species of concern as they relate to the project
x
A discussion of the defined access routes to the project site and project site boundaries within which
project activities must be accomplished
Construction employees would strictly limit their activities, vehicles, equipment, and construction materials to the
project footprint, designated staging areas, and routes of travel. The construction areas would be the minimal area
necessary to complete the project and would be specified in the construction plans. Construction areas would be
demarcated on-site, and employees would be instructed to limit activities to these areas.
3.4.10.2
Cultural Resources
Prior to construction, a qualified archeologist would conduct a training program for construction personnel. The
training program would inform the construction personnel about the possibility of encountering buried cultural
resources and the proper procedures should cultural resources be encountered.
3.4.10.3
Fire Prevention, Suppression, and Safety Program
The project applicant would coordinate with the RMFD and/or HFD to provide training for personnel to safely
interrupt electrical power in the event of emergency incidents requiring fire suppression or rescue activities.
To minimize fire risk, combustible vegetation or agricultural products on and around the project site boundary
would be actively managed by the project owner or its affiliates. Combustible vegetation would either be limited
in height or removed, consistent with fire-safe requirements and dust control standards of the Maricopa County
Air Quality Control District for solar electrical generation facilities.
The project applicant would also implement the following measures during project construction and operation:
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative
page 10
x
All applicable Maricopa County standards and requirements would be followed to ensure accessibility
and ground clearance of emergency vehicles (e.g., fire engines)
x
Smoking would be prohibited at the project site, except within designated areas
x
Work crews would be required to park vehicles away from flammable vegetation such as dry grass and
brush. At the end of each workday, heavy equipment would be required to be parked over mineral soil,
asphalt, or concrete, where available, to reduce the risk of fire
x
All heavy equipment would be required to include mechanisms for fire suppression, including spark
arresters or turbo-charging (which eliminates sparks in exhaust) and fire extinguishers
3.4.11 Perimeter Fencing and Gates
Perimeter fencing would be installed around the project site with gates located at key access points for both the
construction and O&M phases of the project. All fencing and gates would be installed according to the
specifications and requirements established by Maricopa County within the Maricopa County Zoning Ordinance.
Proposed locations of all fencing and gates are illustrated on figures within the Site Plan provided as part of this
application.
3.4.12 Site Security and Outdoor Lighting
Security cameras would be installed along the perimeter of the project site within the project footprint and/or at
the inverters. Cameras will be mounted on poles approximately 20 feet in height and will face inward to monitor
on-site activity.
Outdoor lighting shall comply with Section 1112 of the Zoning Ordinance and all other County standards,
regulations, and requirements. Lighting would be installed at the substation per utility requirements, along
perimeter fencing, at the facility entrances and interior gates, at the O&M facilities, at the inverter and transformer
equipment areas, and at the substations/switching stations. Exterior lighting would be shielded and directed
downward to minimize the potential for glare or spillover onto adjacent properties. Lighting may be either motion
activated or light sensitive to automatically come on in the evening and shut off in the morning.
3.4.13 Permanent Buildings
Ancillary facilities such as the O&M building, septic system and leach field, exterior lighting, signage, SCADA,
telecommunications, and meteorological data collection system may also be installed with the solar arrays.
3.4.13.1
O&M Building
An O&M building to accommodate up to ten permanent O&M staff would be required for the project. The building
would be approximately 2,000 square feet in size (approximately 40 feet by 50 feet by 15 feet high at its tallest
point) and located near the project substation. The O&M building would include permanent plumbing and
restroom facilities for use by the staff. Additional personnel occasionally on-site to perform periodic module
washing (up to four times per year) would be provided with portable restrooms on the project site as well as
bottled water for drinking and hand washing. The O&M building would be constructed on a concrete foundation.
3.4.13.2
Control Enclosures for Relay and SCADA Equipment
The project would include a comprehensive SCADA system to allow remote monitoring of facility operation
and/or remote control of critical components. The fiber optic or other cabling required for the monitoring system
typically would be installed in buried conduit leading to a SCADA system cabinet centrally located within the
project site or a series of appropriately located SCADA system cabinets constructed within the O&M buildings.
The dimensions of each cabinet would be approximately 20 feet long by 8 feet wide by 9 feet high. External
telecommunications connections to the SCADA system cabinets could be provided through wireless or hard-wired
connections to locally available commercial service providers. The SCADA system would interconnect to a fiber
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative
page 11
optic network. Some trenching work may be required to bury fiber optic cables, or such cables may be installed
on overhead poles.
Through the SCADA system, operations staff would be on-call to respond to alerts generated by the monitoring
equipment at the project site and would analyze collected data on an ongoing basis to schedule maintenance.
Facility outputs and performance would be measured against forecast production to identify equipment failure or
abnormalities. Attributes that would be monitored include amount of energy generated, equipment (for example,
inverters and combiners) failure, and weather.
3.4.13.3
Septic System
A septic system may be installed adjacent to the O&M building to support the restroom facilities and sewage needs
of the permanent staff at the O&M building during operation. If a septic system is proposed, approval of septic
system plans will be sought from Maricopa County prior to building permit approval. Personnel who are on-site
to perform module washing (up to four times per year) would be provided with portable restrooms serviced by a
licensed provider. Anticipated peak flow is less than 300 gallons into the leach field per day during project
operation. No surface discharges are proposed, other than natural stormwater runoff.
3.4.14 On-site Drainage Areas
On-site drainage areas have been delineated, and retention basins are proposed in each to provide the required
storage to accommodate the runoff volume from the specified storm event (see Drainage Report). Although none
are currently proposed, if the final design contains retention basins with ponding depths greater than 3 feet, these
basins will be equipped with a perimeter fence. Final grading plans will specify the location, elevation, and volume
of each on-site retention basin. A combination of percolation and/or dry wells may be used to drain the basins
within 36 hours.
Basins have been designed as berms, which will provide storage up gradient of the basins. Solar panels will be
located within the basin areas, elevated sufficiently to avoid the ponded water.
3.4.15 Operation and Maintenance
Upon commissioning, the project would enter the operation phase. The solar modules at the site would operate
during daylight hours 7 days per week, 365 days per year. The energy storage system would store and dispatch
power during both daylight and non-daylight hours as required by grid operators year-round.
Operational activities at the project site would include:
x
Solar module washing
x
Vegetation, weed, and pest management
x
Security
x
Responding to automated electronic alerts based on monitored data, including actual versus expected
tolerances for system output and other key performance metrics
x
Occasional equipment repair and replacement
x
Communicating with customers, transmission system operators, and other entities involved in facility
operations
3.4.15.1
O&M Workforce
Up to 10 permanent staff could be on the site at any given time for ongoing facility maintenance and repairs. The
duration of scheduled maintenance activities would vary in accordance with the required task but could involve up
to 25 workers full time for up to 2 weeks up to 4 times a year for module washing and a similar number and
duration for workers regularly visiting the site for routine maintenance activities, including maintenance of the
energy storage system. On intermittent occasions, up to 40 workers could be remotely dispatched to the site if
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative
page 12
repairs or replacement of equipment were needed in addition to module washing. A record of inspections would
be kept on-site. The maximum number of staff on-site at any time would be 75 (10 permanent staff and 65
temporary staff). The personnel and time required for emergency maintenance would vary in accordance with the
necessary response.
The operational labor force is expected to be from the Phoenix metropolitan area with a maximum anticipated
commute of 85 miles one way.
3.4.15.2
Site Maintenance
Project site maintenance would be largely conducted during daytime hours. Equipment repairs and preventative
maintenance could take place in the early morning or evening when the plant would be producing the least amount
of energy. Key program elements would include maintenance activities undertaken by staff at the on-site O&M
building and on-site maintenance as required to clear weeds for ground-mount systems.
Maintenance typically would include module repairs; module washing; maintenance of transformers, inverters,
high-voltage systems, and other electrical equipment as needed; maintenance of the substation, including the
oil/water separator system; and road and fence repairs. Visual inspections of the transformers and the oil/water
separator system would be conducted monthly. On-site vegetation would be managed to ensure access to all areas
of the site.
Solar modules would be washed as needed (up to four times each year) using light utility vehicles with tow-behind
water trailers, as needed, to maintain optimal electricity production. No chemical cleaners would be used for
module washing.
As part of ongoing O&M, the energy storage system would be inspected once a year at minimum. Regular
preventative maintenance would include checking security of DC and AC connections; replacement of fans, filters,
and pumps as required or recommended; fire suppression system inspection as required; and validating
measurements of key electrical and environmental sensors.
Typical equipment used during O&M would include pickup trucks, tractors, and portable water trailers.
3.4.15.3
Fire Prevention, Suppression, and Safety Program
During the O&M phase of the project, the Fire Prevention, Suppression, and Safety Program, including all training
and practices, would be consistent with those described above under construction activities.
3.4.15.4
Site Safety and Security Plan
The project is proposed in an unincorporated area of Maricopa County, where law enforcement responsibility and
services are provided by the Maricopa County Sheriff’s Office. The project is designed to avoid placing additional
burden on the resources of the Maricopa County Sheriff’s Office through the implementation of the following
Security Plan.
CONTROLLED ACCESS
The solar facility would be accessed by gated entrances equipped with KnoxBox or similar emergency access
systems. The entrances would feature locked gates approximately 7 feet high.
LIGHTING
Motion sensitive, directional security lights would be installed to provide adequate illumination around the
substation areas, each inverter cluster, at gates, and along perimeter fencing. All lighting would be shielded and
directed downward to minimize the potential for glare or spillover onto adjacent properties. All lighting also would
conform to applicable Maricopa County rules and regulations for outdoor lighting.
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative
page 13
OTHER SECURITY MEASURES
Off-site security personnel could be dispatched during nighttime hours or could be on-site, depending on security
risks and operating needs. Infrared security cameras, motion detectors, and/or other similar technology would be
installed to allow for monitoring of the site through review of live footage 24 hours per day, 7 days per week.
Such cameras or other equipment would be placed along the perimeter of the facility and/or at the inverters.
Security cameras located at the inverters would be posted on poles approximately 20 feet high.
SIGNAGE
During all phases of the project, signage for safety and identification would be posted around the perimeter of the
project site. No large billboards or other forms of advertising signage are proposed. All signage would conform to
Maricopa County requirements.
3.4.15 Water Requirements
During the construction phase, it is anticipated that up to 350 acre-feet of water would be used for dust suppression
and other purposes. Water used during construction could come from an on-site well, a nearby well, or could be
trucked to the site from a source within 60 miles of the site.
During the O&M phase (which could last up to 40 years), up to approximately 10 acre-feet of water would be
required per year for module washing and maintenance and for the O&M building restroom facilities.
3.5
Decommissioning and Site Reclamation
3.5.1
Decommissioning of Facilities
The project is anticipated to have an operating life of up to 40 years. After this period, the project would be either
repowered or decommissioned. Project decommissioning would involve the removal of above-grade facilities,
buried electrical conduit, and all concrete foundations. Equipment would be repurposed off-site, recycled, or
disposed of in a landfill as appropriate. Some or most of the PV modules would be recycled or repurposed.
After the operating life of the project is complete, the energy storage system would be decommissioned along
with the rest of the solar facility. Some or most battery components would be recycled, and other components
may be disposed of as hazardous waste, depending on available technology. Li-ion batteries and their constituent
parts will likely be recycled. Some batteries may have the capacity to be reused at the end of the operating life of
the project.
Decommissioning would take approximately 13 months to complete and would occur in 3 phases: Phase 1 would
involve shutting down the systems and removing hazardous materials and wiring; Phase 2 would include
removing the PV modules, inverters, and substations; and Phase 3 would include removing site fencing and
driveways and the final soils reclamation process.
Decommissioning would involve the use of heavy equipment similar to that used for construction. Appropriate
hazardous materials control and erosion control measures would be used throughout the decommissioning
process. It is anticipated that such controls would be substantially similar to those implemented during
construction, although the intensity of activities would be lower.
3.5.2
Site Reclamation
All roads, driveways, and other areas compacted during original construction or by equipment used for
decommissioning would be tilled in a manner adequate to restore the sub-grade material to the proper density and
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative
page 14
depth consistent with adjacent properties. Low areas would be filled with clean, compatible sub-grade material.
After proper sub-grade depth is established, locally sourced topsoil would be placed to a depth and density
consistent with adjacent properties. Locally sourced compost would be applied to the topsoil, and revegetation
with native seeds or plantings would be accomplished.
4.0 RELATIONSHIP TO SURROUNDING PARCELS
4.1
Project Site Parcels
The size of the Zoning with Overlay change is 2805.23 acres. All parcels in the project footprint are currently zoned
RURAL-43 and designated “Utilities” on the Comprehensive Plan Map. To accommodate the proposed
development, the zoning designation would be converted to IND-2 with an IUPD. Table 1 below lists individual

Surrounding Parcels
The subject property is located adjacent to the Delaney Substation, minimizing the amount of additional power
lines required to facilitate connection to the regional electrical system. The project site is also located near an
existing energy generation facility, the Harquahala Generating Station, 1 mile west of the proposed project site at
the intersection of Thomas Road and 491st Avenue. Thus, the project site is bookended to the west by the
Harquahala Generating Station and to the east by the Delaney Substation; with the construction of the project, the
lands between these two significant pieces of energy infrastructure would be consistent with the surrounding
context of energy generation.
The project site is bisected by property owned and managed by the Maricopa County FCD, and there are canals
and roads within the project site that are within the Harquahala Valley Irrigation District’s ROW. This project
would avoid development within floodplains, with the exception of the proposed 34.5-kV electrical collection
lines described in section 3.4.4 of this Narrative that would span the floodplain in order to connect two non-
contiguous portions of the project. The applicant, RE Papago LLC, intends to obtain an easement and ROW
permit from the FCD of Maricopa County for these collection lines as well as for any construction activities that
traverse the real property of the FCD of Maricopa County. RE Papago LLC will also avoid all development in
the Harquahala Valley Irrigation District’s ROW (extending generally 25 feet from the centerline of irrigation
canals) and seek a perpetual agreement with the Harquahala Valley Irrigation District for use of roads in the
Harquahala Valley FCD’s ROW.
Other adjacent land uses include industrial and rural. Adjacent to the north of the project, the majority of the land
is administered by the Arizona State Lands Department (ASLD). All land use to the north of the project is
classified as Rural Density (0-1) and is zoned as RU-43 (Rural). Adjacent the east of the project, all land is
administered by the ASLD, with the exception of the APS-owned Delaney Substation located adjacent the
southeast corner of the project. All land use here is designated as Rural Density (0-1) and is zoned as RU-43.
Adjacent to the south of the project, the majority of land is administered by the ASLD, the FCD of Maricopa
County and the BLM. Land use to the south of the project is classified as a mix of Rural Density (0-1) and
Industrial, and is zoned as RU-43, C-2 (Intermediate Commercial) and C-3 (General Commercial). Adjacent to
the west of the project, land use is classified as a mix of Rural Density (0-1), Rural Development Area and
Industrial (adjacent to the southwest corner of the project). All zoning adjacent to the west of the project is zoned
as RU-43. The project, as proposed, will be compatible with both industrial and surrounding residential uses. The
project would not produce, use, store, transport, or dispose of hazardous materials as defined in Title 40, Part 335
of the Code of Federal Regulations. Materials such as fuels, inverter coolant, transformer oil, and batteries
installed as part of the energy storage system would be used during construction, operation, and decommissioning
of the proposed project. These materials are subject to local, state, and federal regulations to minimize risk and
exposure to the public and to the environment.
4.3
Benefits to the Community and Surrounding Area
4.3.1
Economic Benefits
During recently conducted public involvement activities for the Major Comprehensive Plan Amendment and the
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative
page 16
Zone Change applications, one important public interest voiced by those who participated was the availability of
jobs created as a result of the project for interested local citizens. The project as proposed will create the need for
a variety of new skilled jobs. Project construction is anticipated to take up to 24 months but could last up to 36
months and will need an estimated workforce of 240 to 500 full-time employees. During operations, there will be
up to 10 permanent full-time employees for ongoing facility management, up to 25 part-time employees for
regularly scheduled module washing and routine maintenance activities, and up to 40 employees on an intermittent
basis for equipment replacement or repair.
4.3.2
Environmental Benefits
The project is a 300-MW solar electric generating and storage facility, which will increase the amount of
renewable energy available to a growing Maricopa County. Tangible environmental benefits from the project
include a reduction in greenhouse gas emissions over the life of the project as well as a corresponding reduction
in emissions that adversely impact air quality. The applicant and its consultant, Transcon Environmental, have
also completed initial screenings in the area of the project for biological resources and cultural resources and have
determined that the subject property does not contain unique habitats, threatened or endangered species, or
important cultural resources. There will not be significant adverse impacts to the natural environment. Visually,
the infrastructure associated with the solar energy generation and storage will be low lying; thus, the impacts to
scenic quality will be limited and highly localized. Additionally, the project will benefit air quality in Maricopa
County and beyond.
4.4
Recent Changes in the Area That Support the Application Request
In addition to the zoning change requested, RE Papago LLC received approval for a Major Comprehensive Plan
Amendment and a related General Comprehensive Plan Amendment for the subject project. This is in line with a
number of other recently approved Comprehensive Plan Amendments for solar energy generation surrounding,
abutting, and immediately adjacent to the proposed project site, including the Sun Valley North, Sun Valley
South, Harquahala Solar, and Almeria Solar projects.
5.0 LOCATION AND ACCESSIBILITY
5.1
Project Location
The project site is located in the western region of unincorporated Maricopa County, south of I-10 and
approximately 5.5 miles west of the community of Tonopah, Arizona. The project site’s location is generally
north of West Courthouse Road, northwest of the Delaney Substation and the junction of West Courthouse Road
and West Salome Highway, east of 491st Avenue, and south of I-10. Indian School Road and West Salome
Highway extend through parts of the project site.
5.2
Accessibility
As the project is located immediately south of I-10, it is anticipated that I-10 would serve as the primary corridor
for both construction traffic and operational traffic serving the proposed project. From I-10, the primary arterial
roads that will be used to access the project site are existing roads, including West Salome Road, Indian School
Road, and West Courthouse Road. From these arterial roads, there are a number of smaller, existing roads, both
named and unnamed, that traverse the project site, which are anticipated to be used and improved for construction
and ongoing operations of the project.
6.0 CIRCULATION SYSTEM
6.1
On-Site
On-site access would consist of only those required for vehicle access and maintenance activities. Roads would
typically be constructed to be 14 feet-wide or less and would be paved or graveled as needed for access and dust
RE Papago Photovoltaic Solar Energy Generation and Storage Project
Zone Change with Industrial Overlay Narrative
page 17
control during construction and O&M phases.
There are no existing access roads within the project on-site boundaries and thus, no improvements are necessary.
6.2
Off-Site
The MCDOT has requested ROW dedications/reservations along the following alignments, which the applicant,
RE Papago LLC, has agreed to:
x
Salome Highway: dedicate to 130 feet (65 feet either side of road centerline) (existing ROW is 66 feet
total)
x
Salome Highway through APNs 506-31-059 and 506-31-061: dedicate to 130 feet (65 feet either side
of road centerline)
x
Indian School Road (west of Salome Highway): preserve 25 feet half-width and/or 50 feet full- width
x
Indian School Road along parcel APN 506-31-059: dedicate to 65 feet
x
Indian School Road along parcel APN 506-31-005: dedicate to 65 feet
x
467th Avenue: preserve 65 feet half-width
x
Campbell Avenue east from Salome Highway to 267th Avenue: preserve 25 feet
There would be no significant increase in traffic during the operational life of the project that would require road
improvements. There would be an increase in the level of traffic during the up to 36 months required for project
construction. This increased traffic would result primarily from the delivery of equipment and supplies and the
commuting of the construction workforce. A detailed traffic impact analysis has been completed as part of the
zoning change process and is included in the application package. RE Papago LLC has agreed to financial
responsibility for repair of roads used during construction, including bonding for such work, so that there is no
public expenditure required for transportation infrastructure associated with the project.
7.0 DEVELOPMENT SCHEDULE
Below is an indicative schedule for development:
x
Q3 2021—Attain all required approvals and permits which may include, but not be limited to the
following: Zone Change with Industrial Overlay, Major Comprehensive Plan Amendment, General

Screening
A solid masonry wall not less than six feet in
height shall be required along and adjacent to
any side or rear property line abutting any
rural or residential zone boundary, or any
alley abutting such zone boundary. Further,
any access gates shall be constructed of view-
obscuring material to provide effective site
screening.
6’ minimum chain-link
fencing (with 1’ of
barbwire permitted)
Because of the low profile of the solar PV panels and because
the site is not located near any population centers or heavily
travelled roads, landscaping, solid walls or other screening
methods would not be required to mitigate a visual impact.
The proposed solar PV panel arrays would be visible from
viewpoints along public roads including West Salome
Highway and Indian School Road, but would be located on
relatively flat lands, and would not block or obscure landscape
views through the site. Chain-link fencing would be consistent
with other solar energy developments in the area.
Landscaping
5’-20’ landscaping strip required along road
frontages
No landscaping strip
required
Installing a landscaping strip on the site along all road
frontages would be cost prohibitive. The project is
designed to minimize the disruption of natural vegetation
as much as possible. Existing natural vegetation will
remain undisturbed along front setback areas.

Utility pole heights up to 140 feet are requested because
utility structures 120 feet or less in height may be
infeasible due to final electrical design considerations. The
applicant’s current preliminary, conceptual designs
indicate that high-voltage dead-end structures up to 127
feet in height may be required, as shown on Sheet C3.2 of
the Site Plan; however, final design has not been
determined yet and the gen-tie may require structures up to
140 feet in height. The applicant requests the flexibility to
make the necessary adjustments, as needed, for future final
designs.
Additional
Regulations
All uses except for parking, loading,
unloading or storage shall be conducted within
a completely enclosed building.
Utility uses are permitted
to be conducted outside of
an enclosed building.
The 2,000-square foot Operations and Maintenance
(O&M) building would be the sole staffed structure on the
site. The operating uses of the site include energy
generation and storage, which would take place within the
solar PV arrays and Battery Energy Storage System
(BESS), respectively, and would not take place within
enclosed structures (with the exception of the unstaffed
project substation and SCADA/control system enclosure).

Mr. Adam Cannon
Maricopa County Planning & Development Department
501 N. 44th Street, Suite 200
Phoenix, AZ 85008
Electronically submitted to: adam.cannon@maricopa.gov
RE: Papago PV Solar Energy Project
Dear Mr. Cannon:
At the request of Maricopa County, the Arizona Game and Fish Department (Department) has
reviewed the Zone Change Narrative for the proposed solar facility in unincorporated Maricopa
County, south of I-10 and approximately 5.5 miles west of the community of Tonopah, Arizona.
The Department understands that RE Papago LLC (Recurrent Energy) is proposing the
development of a photovoltaic solar facility, with the construction of one electrical substation,
associated overhead and underground 34.5 kV electric lines, and an energy storage system on
approximately 2,791.2 acres of privately owned land.
Under Title 17 of the Arizona Revised Statutes, the Department, by and through the Arizona
Game and Fish Commission (Commission), has jurisdictional authority and public trust
responsibilities for management of the state's fish and wildlife resources. It is the mission of the
Department to conserve and protect Arizona’s diverse fish and wildlife resources and manage for
safe, compatible outdoor recreation opportunities for current and future generations. Similarly,
the Department recognizes the importance of planning efforts that contribute to the county and
the state’s economic growth needs and opportunities to develop renewable energy locations. The
Department recognizes that appropriate coordination, proper planning, and voluntary
implementation of best management practices allow projects to be developed that avoid,
minimize, or mitigate potential impacts to wildlife habitat and populations.
To the extent possible, the Department encourages pre-construction surveys and monitoring to
determine species presence as referenced in our Guidelines for Solar Development in Arizona .
The Department is available to review survey designs, provide input on developing
best-management practices, and are available to assist in developing this economically-important
facility while also minimizing any potential impacts to wildlife during construction and operation
of the facility.
Based on Department data, a portion of the project area has been used by the 10J designated,
experimental nonessential population of the endangered Sonoran pronghorn. Sonoran pronghorn
Papago PV Solar Energy
May 26, 2021
Page 2
have specific habitat requirements based on their life history and survival strategy. This
population is relatively new and its range is expanding into previously unused areas. Based on
the proposed location of the project, the Department would welcome the opportunity to work
with Maricopa County and Recurrent Energy to minimize any potential impacts to Sonoran
pronghorn. The Department recommends the following measures to avoid and minimize
potential impacts:
●
Coordination between the Department and Recurrent Energy prior to construction
activities in order to exchange information on current Sonoran pronghorn use in the
project area.
●
If pronghorn are detected during construction activities, please notify the US Fish and
Wildlife Service, Arizona Ecological Services Office (AESO) and the Department’s
Sonoran Pronghorn Program Lead ( jbright@azgfd.gov ) as soon as possible.
The Sonoran desert tortoise ( Gopherus morafkai ) is a Candidate species for listing under the
ESA and has been recorded within the vicinity of your project. . The Department recommends
conducting a survey for Sonoran desert tortoise within suitable habitat, in accordance with the
Desert Tortoise Survey Guidelines for Environmental Consultants, to determine the
presence/absence of this species. If tortoises are identified during the survey, please refer and
adhere to The Recommended Standard Mitigation Measures For Projects In Sonoran Desert
Tortoise Habitat and Guidelines For Handling Sonoran Desert Tortoises Encountered On
Development
Projects.
All
of
these
documents
can
be
found
at
https://www.azgfd.com/wildlife/nongamemanagement/tortoise/.
The western burrowing owl ( Athene cunicularia hypugaea ) is a special status species that is
regulated under the Migratory Bird Treaty Act (MBTA). If suitable habitat for this species is
present within or adjacent to your project area, the Department recommends conducting an
occupancy survey for western burrowing owls to determine if this species occurs within your
project footprint. Guidelines for conducting this survey are found in Burrowing Owl Project
Clearance Guidance for Landowners which can be accessed on-line through the Department’s
website. Please note that the survey should be conducted by a surveyor that is certified by the
Department. If an active burrowing owl burrow is detected, please contact the Department and
the U.S. Fish and Wildlife Service for direction, in accordance with the Burrowing Owl Project
Clearance Guidance for Landowners .
The Department would like to provide the following general recommendations:
●
During construction activities, if wildlife such as the Sonoran desert tortoise are
encountered, please contact the Department to discuss relocation. This also applies to any
wildlife that may need to be removed from the facility once it is operational. The
Department requests the facility provide an annual report of any animal
sightings/occurrences during the construction and operation of the facility. Additionally,
please share wildlife related mortalities from facility operation(s) to pep@azgfd.gov.
●
Sonoran desert habitats and its associated fauna are highly dependent on the minimal
precipitation received each year. The resulting sheet flows contribute significantly to the
hydrology of areas where rain events often occur in isolated patches. Any disruptions to
Papago PV Solar Energy
May 26, 2021
Page 3
surface flows, both in washes and across uplands, could lead to mortality of desert
vegetation and potentially change wildlife species distributions and abundance beyond
the project footprint. The Department recommends avoiding all washes and/or changing
the hydrology of the site.
●
Artificial night lighting, may attract insects and the species that prey on them (e.g. bats).
It could also impair the ability of nocturnal animals to navigate. The Department
recommends using only the minimum amount of light needed for safety. If feasible,
narrow spectrum lighting is wildlife-friendly and should be used as often as possible to
minimize the number of species affected by lighting. It is also beneficial that all lighting
is shielded, canted, or cut to minimize the amount of upward shining light.
●
Birds of prey such as raptors, owls, vultures, and eagles are vulnerable to electrocution
and powerline strikes during construction and operation. There are a number of design
features that can minimize these impacts to these important species. Tuk Jacobson is the
Department’s raptor expert and will be willing to share information on best management
practices; he can be contacted at KJacobson@azgfd.gov or 623-236-7575.
●
Power poles can serve as perches for many birds of prey and there are design features for
structures that can reduce impacts to these important species. Another possible alternative
to reduce mortality is using bird flight diverters to decrease avian mortalities. Again, Mr.
Jacobson has expertise in all of the best management practices and would be available to
share his knowledge in the pre-design phase of this project.
Thank you for the opportunity to provide comments on this proposed project. The Department
looks forward to continued communications with Maricopa County and Recurrent Energy
regarding project development and implementation. Please contact me at 623-236-7222 or
ACavalcant@azgfd.gov if you have any questions, or would like to further discuss our concerns
and recommendations.
