Project Summary:
1.
The applicant, Wood Group USA, Inc., is requesting a Major Comprehensive Plan Amendment
(CPA) to change the land use designation in the Vision 2030 Maricopa County Comprehensive
Plan from Rural Development Area to Utilities to allow the development of a utility-scale solar
electric generating project. The project will include solar (photovoltaic) modules and a battery
energy storage system (BESS). The project will have an electrical generation capacity of up to
550 megawatts alternating current (MWac). Likewise, the BESS will have a net power capacity of
up to 550 MWac. Due to the size of the project (1,150 acres), a major CPA is required. The
applicant will be subsequently required to obtain a zone change with overlay to IND-2 IUPD as
part of the entitlement process. A precise plan of development will also be required, either
concurrent with or following approval of the zone change with overlay.
2.
This request for a major CPA is the second such request for the Maricopa Energy Center Project
(originally the Maricopa Solar and Storage Project). In 2020, the Maricopa County Board of
Supervisors approved CPA2020002, which changed the land use designation in the
Comprehensive Plan from Rural Development Area to Utilities on 11,260 acres. Since approval of
this CPA, the project area has been significantly reduced in size. Of the 11,260 acres subject to
CPA2020002, only 3,115 acres will continue to be subject to the project area. Approval of this
request would add 1,150 acres to the project area, for a total project area of 4,265 acres.
3.
This request includes 19 privately owned parcels. Most properties in the immediate vicinity of the
project are also privately owned. According to the narrative, site control options have been
secured for all parcels, as well as the remaining parcels within the project area that were
previously subject to CPA2020002.
4.
Nearly all land used for solar energy projects is developed for large fields of solar collectors that
capture the energy through photovoltaic technology. The project area is relatively flat and allows
for development of solar facilities with little or no additional grading. The subject parcels are
currently native desert land, although many of the nearby properties (including many within the
project area that were subject to CPA2020002) are currently used for row crop cultivation. A
portion of the Centennial Wash is located south of the site, though the narrative assures that no
impacts on the Centennial Wash will occur. Additionally, the general area includes significant
local electrical infrastructure, including a power generation facility, a substation, and a future
interconnect to the APS Delaney Substation.
5.
Adjacent land uses include vacant, agricultural, industrial (utility plants), and very limited rural
residential uses. Previous CPAs for the Almeria Solar Project and Harquahala Solar Project were
approved in 2011 under an older land use designation, although these projects were subsequently
abandoned. More recently, CPAs were approved for the Papago Solar Project nearby to the east.
The APS Delaney Substation and Harquahala Power Plant are located east of the project area.
The interconnect line associated with the project will connect to the APS Delaney Substation.
6.
The narrative asserts that the proposed development meets the Comprehensive Plan
Amendment criteria in the following manner:
Whether the amendment constitutes an overall improvement to the Comprehensive Plan and is
not solely for the good or benefit of a particular landowner or owners at a particular point in time.
The narrative states that the Maricopa Energy Center Project is in direct alignment with the
County’s mission and guiding principles for leadership and strategic priorities. According to the
CPA2023011
Page 3 of 10
narrative, the project would benefit the State, County, local, and regional economy by providing
employment for several hundred crafts over a 2-to-3-year construction window, beginning as early
as 2025. The project will create up to 100 construction jobs per month for 24 months and could
hire as many as 300 workers during peak construction. The applicant will make efforts to hire
individuals from the local area and region. The project will generate revenue opportunities for
local businesses, and the energy generated by the site will supply the County, State, and
Southwest region with electricity. Additionally, there will be little transportation infrastructure or
water resources required to serve the site. Therefore, the Amendment constitutes an overall
improvement to the Vision 2030 Maricopa County Comprehensive Plan and is not solely for the
good or benefit of a particular landowner (or owners) at a particular point in time.
Whether the amendment will adversely impact all or a portion of the planning area.
A. Altering acceptable land use patterns to the detriment of the plan – According to the
narrative, this amendment will not alter any surrounding land uses or land use patterns. The
land is currently used as agricultural land. While this land will be unavailable during the life of
the project, the land can return to its agricultural function when the project ceases. Moreover,
this site is situated near other solar developments and comprises a key use-sector of
unincorporated Maricopa County, including utilities (solar and electric generating stations)
and agriculture.
B. Requiring public expenditures for larger and more expensive infrastructure – The narrative
states that the project would not require public expenditures for larger or more expensive
infrastructure. The costs of the project’s infrastructure needs shall be borne by the applicant.
C. Requiring public improvements to roads, sewer, or water systems that are needed to support
the planned land uses – The narrative states that the project would require improvements to
roads (underground cabling and access), septic, and a potable water system associated with
the O&M building to support the planned land use. Existing roads will serve the project and
any additional project infrastructure needs shall be borne by the applicant.
D. Adversely impacting planned land uses because of increased traffic – The narrative
indicates there would be no significant increase in traffic during the operational life of the
project following the construction phase. With a small number of staff operating the O&M
building during the project’s operating life, planned uses overall will not be adversely
impacted. Potential impacts on traffic during the construction period will be addressed during
review of the subsequent zone change or plan of development, and a construction traffic plan
will be developed to minimize impacts on existing land uses and access to these land uses.
E. Affecting the livability of the area or health or safety of present and future residents – During
construction, dust control measures shall be utilized to minimize fugitive dust generation. Air
emissions will occur from construction equipment; however, long-term air quality will improve
because of the project. Additionally, the project will follow federal, state, and local regulations
regarding the production, use, storage, transport, or disposal of hazardous materials. Wildfire
prevention and mitigation measures will be incorporated into the Plan of Development. Fire
hazard risks will be managed through weed control. Therefore, the project will not affect the
livability of the area or health or safety of present and future residents.
F. Adversely impacting the natural environment or scenic quality of the area in contradiction
to the plan – The applicant states that the project will not significantly impact the natural
environment or overall scenic quality of the area. There are key measures of responsibility
CPA2023011
Page 4 of 10
that demonstrate an applicant’s commitment to avoiding adverse impacts to the natural
environment and scenic quality of a site. These measures are subjective in a sense, but may
include animals, plants, historical resources, scenic views, and hydrology/ground disturbance.
Animals – The applicant has conducted pre-construction wildlife surveys to identify habitats
for creatures. Online tools provided by the Arizona Game and Fish Department (AGFD) and
the US Fish and Wildlife Service (USFWS) were also queried for information on special status
species, including federal threatened and endangered species. No such species or their
associated habitats were identified during these assessments. There is the potential for State
Species of Concern to occur, including three bird species protected under the Migratory Bird
Treaty Act (MBTA). To comply with the MBTA, ground disturbance and vegetation removal
will be avoided to the extent possible during the breeding season for all migratory species. If
construction must take place during this time, pre-construction nest surveys will be
conducted by a qualified biologist. The applicant will consult with USFWS to develop
measures (such as buffers or construction timing restrictions) to prevent disturbing any nests
that may be found. Additionally, project staff and contractors will follow AGFD guidelines for
handing Sonoran Desert tortoise in the unlikely event that any are encountered during
construction.
Plants – For native species protected under Arizona Native Plant Law, a permit will be
obtained from the Arizona Department of Agriculture (ADA) if salvage or relocation of any
such species identified onsite is required. Native plant removal, relocation, or sale will be
noticed as required by Arizona Administrative Code Title 3, Chapter 3, Article II.
Historical Resources – A Class 1 Cultural Resources Inventory was completed and submitted
to the Arizona State Historic Preservation Office (SHPO) during review of CPA2020002. Two
additional Class I Cultural Resources Inventories, as well as a Class III survey, were completed
in 2022. In response to SHPO recommendations, the applicant will conduct a Class II Cultural
Resources Sample Survey prior to construction. Development will avoid any known
archaeological sites.
Scenic Views – The narrative indicates that the project will not significantly impact the scenic
quality of the area. The solar fields will have a low profile and will not be located near densely
populated areas. The applicant previously submitted a glint/glare assessment for
CPA2020002, which showed that there will be little reflection from the solar array along
existing roads, at two airfields, and at residences. To minimize visual impact, an 80% opacity
screen will be constructed in areas adjacent to existing residences, as required.
Hydrology/Ground Disturbance – According to the narrative, hydrologic conditions will be
preserved by avoiding the Centennial Wash and in accordance with agency requirements. No
Waters of the United States (WOTUS) were identified within the project boundaries, and the
U.S. Army Corps of Engineers (USACE) is currently evaluating a Dry Land Approved
Jurisdictional Determination (AJD). To minimize impacts to surface water runoff, appropriate
best management practices and retention basins will be included during design and
construction. The applicant does not anticipate a need for new roads.
Whether the amendment is consistent with the overall intent of the Comprehensive Plan.
The applicant’s narrative states that the request is consistent with the overall intent of the
Comprehensive Plan. In addition to the State, County, local, and regional benefits, the narrative
asserts that the project displays consistency with the County’s vision to work collaboratively and
CPA2023011
Page 5 of 10
effectively for residents and the County’s mission to provide regional leadership by encouraging
solar energy development. Additionally, the applicant believes that the project aligns with the
County’s priorities to leverage resources, plan for effective and efficient infrastructure, and
manage County resources.
The extent to which the amendment is consistent with the specific goals and policies contained
within the plan.
The applicant’s narrative states that the request is consistent with the specific goals and policies
contained within the Comprehensive Plan. The Plan explicitly identifies encouraging solar energy
development as an important goal and strategy to attract solar and other alternative energy
research and development to Maricopa County. The narrative contains a substantial list of Goals
and Policies from the Vision 2030 Maricopa County Comprehensive Plan. This staff report
identifies which Goals and Policies the applicant’s narrative addressed.

Adopted Plan:
10.
Vision 2030 Maricopa County Comprehensive Plan: The entire site (approx. 1,150 acres) is
designated as Rural Development Area (0 – 1 d.u./ac.). This land use designation encourages
low-density rural residential and agricultural uses.
Public Participation Summary:
11.
The applicant posted the project area and staff notified all property owners within 300’ of the
subject parcels. Pursuant to state law, Staff issued enhanced notification letters to all adjacent
and internal jurisdictions to Maricopa County, select State and regional agencies, and Luke Air
Force Base. Staff received four letters from adjacent / internal jurisdictions (Yuma County, Pinal
County, City of Goodyear, and Pima County) expressing no concerns. Moreover, state agencies
such as Arizona Game & Fish Department (AGFD) issued comments. These comments have been
included in the attachments to this staff report and are not actionable until later review of a plan
of development.
12.
According to the public participation results report submitted by the applicant, the applicant
conducted a virtual open house meeting on September 20, 2023, and was advertised for three
weeks in advance in the Arizona Business Gazette. There were no citizen attendees, although a
recording of the meeting was posted on the project website.
13.
Additionally, the public participation results report included a record of all phone calls and
communications. One of these was a request from a nearby property owner to include his parcel
in the Major CPA and the zone change request that will follow. Similarly, the real estate agent of
another property owner inquired as to whether the applicant would be interested in purchasing
two parcels for inclusion in the project. The applicant responded to both communications
confirming that their respective parcels were not of interest to the project. The remainder of these
communications were information requests, including concerns regarding how the project would
impact the use and value of nearby properties. The applicant responded to all communications,
and no follow-up questions or requests for information were received.
14.
County staff received no correspondence from the public either in support or in opposition.
County staff did receive an email from an adjacent property owner inquiring whether it would be
possible to incorporate his parcel into the CPA request or to rezone the property to an Industrial
zoning district. County staff responded to the owner advising that, because the enhanced routing
had been completed and the legal ad had been published, the Planning & Development
Department was unable to incorporate any additional parcels or land as part of the request.
CPA2023011
Page 9 of 10
Nonetheless, the owner was advised that he was welcome to contact the project applicant to
discuss future options. The owner responded that he had reached out to the applicant, who in
turn declined interest in incorporating his parcel into the project area. The owner thanked County
staff for the correspondence.
Outstanding Concerns from Reviewing Agencies:
15.
N/A.
Staff Analysis:
16.
The State of Arizona and Maricopa County recognize the potential environmental and economic
benefits that solar technology can provide. The Maricopa Energy Center Project will use
photovoltaic technology that generates energy from sunlight absorption. Photovoltaic technology
differs from other techniques that require vast amounts of water to cool the units. By contrast,
very little water is used or needed for photovoltaic technology. As a result, this development would
not create concerns related to groundwater depletion.
17.
Staff believes the proposed solar facility is well suited to this rural area. Solar facilities require
large amounts of relatively flat land, and most of the project area is flat. Staff agrees with the
applicant that the project area is suitable due to its proximity to electrical transmission lines and
nearby stations and substations. The project area is also suitable because the surrounding area
is undeveloped. Staff agrees with the applicant that the project will not detrimentally affect the
visual quality of the area. The applicant engaged in a robust and lengthy public participation
process. Additionally, the applicant corresponded with AGFD regarding wildlife preservation.
Since the area is primarily undeveloped vacant land near other existing utility-scale solar projects,
staff believes there will be minimal impacts to the surrounding area.
18.
Promoting the development of solar energy over the past several years in Maricopa County
reinforces the County’s interest in promoting itself as an economic leader for solar development.
Staff believes the Maricopa Energy Center Project would add to this effort in a positive way by
providing potentially hundreds of jobs over a 2-to-3-year construction window, beginning as early
as 2025. There will also be a small number of long-term employment opportunities for Maricopa
County residents.
19.
Staff believes the Maricopa Energy Center Project is consistent with and meets the goals and
policies of the Comprehensive Plan. Staff’s position is that this project, as proposed, represents
proper long-term land use planning in the region and in Maricopa County as a whole.
Recommendation:
20.
Staff recommends the Commission adopt a motion recommending that the Board of Supervisors
approve CPA2023011.

PART A – EXECUTIVE SUMMARY
This narrative report addresses the required information to support the request for a Major
Comprehensive Plan Amendment (CPA) to change the future land use designation from Rural
Development Area to Utilities for the Maricopa Energy Center Project (Project). Maricopa Energy Center,
LLC (MEC), (Applicant), is proposing the construction and operation of an up to 550 megawatt alternating
current (MWac) electrical generation facility consisting of solar (photovoltaic) modules and a battery
energy storage system (BESS), collectively referred to as the Project. The electrical generation capacity of
the solar Project would be up to 550 MWac and the BESS would have a net power capacity of up to 550
MWac. The BESS would likely be designed to go through a single charge/discharge cycle on a 24-hour
basis, storing/discharging up to 3.2 gigawatt hours (GWh). The Project will be joined with previously
approved CPA application 2020002 (see Table 1 below). This CPA application is for up to 1,150 acres of
private land in the Harquahala Valley west of Tonopah, in unincorporated Maricopa County (County),
Arizona. CPA2023011is located adjacent to the retained 3,115 acres from CPA2020002 (Figure 1). The
combined area of 4,265 acres is intended to be developed for solar power generation and become a
unified development. The table below provides a summary of the previous and current Comprehensive
Plan Amendments, as well as a summary of how the size of the Project site has changed since the
approval of CPA2020002.
The Project would include up to 827,067 solar modules, rated at 665 watts direct current (dc) per module,
and mounted on single-axis trackers. It should be noted that watts per module may vary at the time of
construction; however, for planning purposes we have included an approximate module output of 665 watts
dc. In addition to the installation of solar modules, the Project would include the construction of a Project
substation, BESS warehouse, and operation and maintenance (O&M) building that would include a
connection to a septic system. The Project interconnect, a single circuit 500kV transmission line

within the area included in this application (Figure 2). The Project transmission interconnect is anticipated
to be a 500-kilovolt (kV) transmission line on 160- to 180-foot structures above grade within an up to 200-
foot right-of-way (ROW). The ROW width varies based on the location of the transmission line and available
ROW. The design life of the Project is anticipated to be 40 years.
1.1
On-site and Regional Location
The Project site is situated northwest of Saddle Mountain, south of the Big Horn Mountains Wilderness
Area, and northeast of the Eagletail Mountains Wilderness Area. The HVID Canal is within 0.5 mile of the
eastern boundary of the site. Topographically, the site slopes slightly to the south toward Centennial Wash.
Elevations within the site range between approximately 1,219-1,147 feet above mean sea level. The site is
generally used for irrigated row crop cultivation and was historically native desert land. Some portions of
the site are previously disturbed desert land. Portions of sections 21 and 27 in T2N, R9W occupy Flood Zone
AO, which is characterized by sheet flow of between one and three feet. A Floodplain Use Permit is required
to build in a Zone AO. The Project would request a Floodplain Use Permit from Maricopa County Flood
Control District during the zoning phase of the Project. The HVID Canal and Saddleback Flood Retardant
Structure (FRS) are within 1 mile of the eastern boundary of the Project.
The Project site is primarily open desert land and agricultural crop land and was historically native desert
land. The local area has been heavily modified to support energy infrastructure, including, but not limited
to transportation corridors, pipelines, County-maintained Road network, telecommunications, above and
below ground powerlines, and other planned or built solar farms. The Applicant would make all reasonable
efforts to mitigate potential impacts to the natural and human environments; however, at this early planning
stage the Project buildable area is still being defined. The final layout would be presented during the zoning
phase.
The Project is approximately 12 miles west of Tonopah, within unincorporated Maricopa County, on up to
4,265 acres of land, and is bounded by Interstate 10 to the north, 491st Avenue to the east, Thomas Road
to the south, and a point approximately 2 miles west of Harquahala Valley Road to the west (see Figure 1).
Generally, the center of the Project is located at Harquahala Valley Road and Camelback Road. The point of
interconnection would be at the APS Delaney Substation. The Applicant’s Project consists of multiple parcels
of land within the following Township (T), Range (R) and Sections:
•
T2N/R9W: Sections 9, 10, 11, 13, 14, 15, 16, 21, 22, 27.
•
T2N/R8W: Sections 17 and 18.
This request is for parcels in:
•
T2N/R9W: Sections 13, 16, 21, 22, 27.
•
T2N/R8W: Sections 17 and 18.
The Applicant has secured site control options for all parcels included within the Project boundary
(Figure 3). A list of all parcels within the Project boundary and within 300 feet of the Project boundary can
be found in Attachment A.

1.2
CPA Size and Description of Land Use Types by Acreage
The request is for a major CPA to change the future land use of approximately 1,150 acres from Rural
Development Area to Utilities (Figure 4). CPA2020002 had previously changed 11,260 acres from Rural
Development Area to Utilities, although only 3,115 acres subject to approval of CPA2020002will continue
to be part of the Project.
Land uses within and surrounding the site include rural development, irrigated row crops, aquatic
agriculture, some commercial, utilities, and open space (i.e., native desert land). The majority of the site,
including 1,132 acres subject to this request, is zoned as Rural-43 Zoning District-One Acre Per Dwelling
Unit (RU-43), which allows for both farm and non-farm residential uses, as well as farms and recreational
and/or institutional uses. In addition, the site includes nine acres of land zoned as Intermediate Commercial
Zoning District (C-2), as well as nine acres of land zoned as Multiple-Family Residential Zoning District (R-
5).
1.3
Roads/Transportation Systems Serving the Project
The site is currently accessible from the north off Interstate 10 at Salome Road which runs along the
northeast side of the Project site and through the eastern side of the Project. The Project site is currently
accessible from the southeast by Camelback Road. Harquahala Valley Road bisects the Project site north to
south through the approximate center of the site. Several existing graded and asphalt-paved
major/minor/local/farm roads also exist within the site. Detailed plans identifying proposed access routes
and road design would be defined and presented during the zoning phase of the Project.
1.4
Suitability with Surrounding Land Uses
The site is situated in a prime location within the regional electric grid and in a relatively remote area suited
for renewable energy development. Multiple CPAs were approved in 2011 under an older land use
designation (from Rural Development Area to Industrial) for solar projects on or near the Project site,
including the Harquahala Solar Project (CPA2011002), the Almeria Solar Project (CPA2011009), and Sun
Valley North (CPA2011011). Although these projects were ultimately not developed (resulting in the land
use designation reverting to Rural Development Area), two more recent CPAs for Papago Solar
(CPA2019004 and CPA2019012) were approved to the east of the Project site, resulting in a change to the
land use designation from Rural Development Area to Utilities. Moreover, the CPAs for Papago Solar were
followed by a Zone Change request from Rural-43 to IND-2 IUPD, as well as a Plan of Development. The
County’s approval of these types of uses (i.e., solar farms) demonstrates the suitability of this Project with
surrounding land uses. In addition, the nearby high voltage transmission lines, Harquahala Power Plant, and
APS Delaney Substation enhance the suitability of the Project site for the proposed use.
The site and surrounding area are relatively flat, encompassing a combination of agricultural and native
desert land. Dust generation from the Project is anticipated to be relatively low, as the land would lay fallow
beneath solar arrays with minimal ground disturbance or vehicular activity compared to present activities.
The Project would not generate noise that exceeds state statutes or use water during the production of
electricity. The solar array (up to approximately 15 feet above ground when fully tilted) would be noticeable
up to one-quarter to one-half mile away, generally along roads and nearby residences, but would blend
into the background terrain for sensitive viewers at distances greater than one-half to one mile.

PART B - WHETHER THE AMENDMENT CONSTITUTES AN OVERALL IMPROVEMENT TO THE
COMPREHENSIVE PLAN AND IS NOT SOLELY FOR THE GOOD OR BENEFIT OF A PARTICULAR
LANDOWNER OR OWNERS AT A PARTICULAR POINT IN TIME.
The Project would constitute an overall improvement to the Comprehensive Plan and is not being
developed solely for the good or benefit of a particular landowner or owners. The County places
demonstrable value on alternative energy development, as evidenced by the strategic priorities and core
principles of the County’s Vison 2030 Comprehensive Plan. Maricopa County explicitly identifies
encouraging solar energy development as an important goal, particularly in Economic Growth Policy 10,
Energy Goal 2, Energy Policy 6, and Water Resources Policy 5.
The Project, as a utility-scale renewable energy generation and storage facility, is in direct alignment with
the County’s mission and guiding principles for leadership and strategic priorities to leverage its resources
to provide for a balanced regional economy.
The Project would benefit the local, County, state, and regional economy by providing temporary
employment opportunities for several hundred crafts over a 2 to 3-year construction window, beginning as
early as 2025, finishing by 2027-2029. The Project would create up to 100 construction jobs per month for
24 months. As the construction and assembly ramps up for each construction phase, the Project could hire
as many as 300 workers during peak construction (approximately 3-4 months) which would then taper off
gradually. Some workers typically perform various jobs throughout construction (i.e., grading, posting,
fencing, landscaping, etc.), therefore a single worker could theoretically be continuously hired for weeks or
months. Construction managers typically prefer to hire locally, and if Maricopa County can provide available,
trained, and willing workers, those would be typically given higher priority. However, some of these jobs are
very specialized, and it is common that many workers are ‘traveling workers’ transitioning from construction
site to construction site. Wages typically are above federal minimum wage, and many jobs have benefits,
i.e., paid holiday, health insurance, etc. Further, the Project would generate revenue for local businesses
including construction companies, hospitality and building material businesses, as well as generate
additional revenue locally in the forms of property acquisition, tax revenue and construction permitting.
Due to the decommissioning of coal-fired base load generation in Arizona and the existing tenuous
condition of Lake Mead, this Project is being developed to: 1) support future electrical loads in the absence
of these coal and hydro generators; 2) to secure renewable and storable power for the State of Arizona and
greater southwest; and 3) to provide reasonably priced electricity to the regional grid as well as support
affordable regional electrical generation and water conservation.
The Project would allow for the use of existing powerline corridors, existing road infrastructure and existing
energy transmission, and would require minimal disturbance to topography and natural or cultural
resources to generate solar electricity. Further, the electricity generated by the Project would be distributed
to the regional electrical grid and wider west/southwest regions. The generation of solar electricity could
also result in improved air quality through reduced emissions for electric generation, providing a benefit to
air quality in Maricopa County and the State of Arizona as well as aligning with the County’s Environmental
Goal 1. These Project characteristics uphold the County’s Comprehensive Plan strategies, goals, and policies
and constitute an overall improvement to the comprehensive plan, local and regional economy, and

regional energy production, that is not solely for the good or benefit of a particular landowner or other
Project proponent at a particular time.
3
PART C - WHETHER THE AMENDMENT WILL ADVERSELY IMPACT ALL OR A PORTION OF THE
PLANNING AREA BY:
3.1
Altering Acceptable Land Use Patterns to the Detriment of the Plan.
The Project would not alter acceptable land use patterns that would be detrimental to the Comprehensive
Plan. Most of the land uses within the site are associated with agriculture. These land uses would be
temporarily unavailable during the life of the Project (i.e., 40 years). Agricultural practices could resume at
the end of the design life of the Project. Other existing land uses within the site are open space (i.e.,
undeveloped native desert land), and utilities. These land uses would continue with the implementation of
the Project.
3.2
Requiring Public Expenditures for Larger and More Expensive Infrastructure.
The Project would not require any public expenditures for larger and more expensive infrastructure. All costs
of larger or more expensive infrastructure required as a result of the Project, such as gen-tie line and on-
site collection lines and required site access improvements, shall be borne by the Applicant.
3.3
Requiring Public Improvements to Roads, Sewer, or Water Systems that are Needed to Support the
Planned Land Uses.
All costs of public improvements to roads, sewer or water systems required as a result of the Project would
be borne by the Applicant. The Project would require improvements to roads (e.g., underground cabling
and access), septic, and potable water system associated with the O&M building to support the planned
land use. The Project area is served by existing roads and the temporary Project construction traffic is not
anticipated to overburden the existing road system. Costs of the Project’s infrastructure needs, such as
access road improvements, Maricopa County Department of Transportation (MCDOT)-requested road
improvements (e.g., Project required underground conduit and wiring, entrance road apron), septic, limited
temporary and operational water needs and domestic waste, would be borne by the Applicant. Water for
construction and O&M would utilize on-site water wells associated with the Project.
3.4
Adversely Impacting Planned Land Uses Because of Increased Traffic.
The Project would not affect planned land uses during either construction or operation. Access to all
existing land uses within the Project area would remain open and unaffected. Potential traffic alterations
would be addressed as part of the entitlement process for the future zone change application and plan of
development for this Project. A construction traffic plan would be developed to minimize impacts on
existing land uses and access to these land uses.
3.5
Affecting the Livability of the Area or Health or Safety of Present and Future Residents.
The Project would not have an impact on livability or health or safety of present or future residences within
the Project area. Currently there is electrical infrastructure (e.g., transmission corridors, solar electrical
generating facilities) as well as above-ground electrical distribution lines and transportation networks within
the Project area and the region. The Applicant understands that the County would require a site enclosure
and screening to provide screening where the Project is adjacent to existing residences. This screening
CPA2023011Major Comprehensive Plan Amendment Application Project Narrative
Maricopa Energy Center Project
October 3, 2023
Page 6
would be at 80% opacity per County direction. Specific type and location of site enclosures and screenings
would be determined during the entitlement process to meet County zoning requirements. Project site
preparation and construction would generate some emissions due to the use of construction equipment
and dust control measures would be implemented to minimize fugitive dust emissions. Project operations
would not generate air emissions; Project maintenance would generate minimal vehicle and equipment
emissions and fugitive dust emissions from personnel accessing the Project site and utilizing limited vehicles
or equipment. The Project would be managed in accordance with local, state, and federal regulations to
minimize risk and exposure to the public and the environment.
Wildfire prevention and mitigation measures would be incorporated into the Specific Plan of Development
that would be developed during Project zoning. All applicable local and County fire laws and regulations
would be complied with, and all reasonable measures would be taken to prevent fires on the site. Fire hazard
risk may be reduced through the control or suppression of weeds. All weed control would be conducted in
compliance with County regulations. Herbicides would likely be necessary to control the spread of invasive
weeds following construction disturbance as part of an integrated pest management strategy.
3.6
Adversely Impacting the Natural Environment or Scenic Quality of the Area in Contradiction to the
Plan.
The Project would not adversely impact the natural environment or the scenic quality of the area
significantly. The Project will submit a biological resources report that discusses fauna and flora within the
Project area. In addition to a field site investigation, the US Fish and Wildlife Service (USFWS) Information
for Planning and Consultation website and the Arizona Game and Fish Department (AZGFD) Online
Environmental Review Tool have been queried for information on special status species, including federal
threatened and endangered species, for the Project area. No federally listed species or their associated
habitats were identified during this assessment.
In May 2020, Ecosphere Environmental Services conducted a field review of the Project and found that
suitable habitat was not encountered for any federally listed threatened or endangered species. There is,
however, potential for a variety of State Species of Concern to occur. The State of Arizona has identified
these species as having the potential to become threatened or endangered without intervention but are
not currently protected under law. The exceptions are the three bird species: LeConte’s thrasher, ferruginous
hawk, and savannah sparrow, which are protected under the Migratory Bird Treaty Act (MBTA).
To comply with the MBTA, it is suggested that, if possible, ground disturbance/vegetation removal be
avoided during the breeding season for all migratory species. The breeding season varies by species and
region, but for the Sonoran Desert it is generally considered to be March 1 to August 31 (raptors breed in
early February through May). If construction takes place during this time frame, a pre-construction nest
survey will need to be conducted by a qualified biologist 7 to 10 days prior to the onset of construction. If
nests are found, it may be necessary to consult with USFWS to develop measures to prevent disturbing
nests. Measures typically consist of a 100- to 200-foot buffer around the nest and/or construction timing
restrictions. Nesting should not be a concern for ferruginous hawks and savannah sparrows as these species
only have the potential to occur during the non-breeding season.
For native species protected under the Arizona Native Plant Law, it will be necessary to obtain a permit from
the Arizona Department of Agriculture (ADA) if salvage of Arizona protected plants is required. While
CPA2023011Major Comprehensive Plan Amendment Application Project Narrative
Maricopa Energy Center Project

Page 7
Sonoran Desert tortoise are not anticipated in the project area, AZGFD has developed guidelines for
handling Sonoran Desert tortoise on development projects, which should be provided to all Project staff
and contractors in the unlikely event a Sonoran Desert tortoise is encountered during project construction.
Native plants protected under Arizona Native Plant Law, administered by the Arizona Department of
Agriculture, will be identified on the site prior to construction and relocated or salvaged as required. Native
plant removal, relocation, or sale will be noticed as required by Arizona Administrative Code Title 3, Chapter
3, Article II. Further, the Project will avoid the Centennial Wash Floodway as well as identified Waters of the
United States and wetlands. The Project conducted a Jurisdictional Delineation to identify potential Waters
of the United States (WOTUS) on August 1 and 2, 2022. No potential WOTUS were identified and on October
24, 2022, a Dry Land Approved Jurisdictional Determination (AJD) application was made to the United States
Army Corps of Engineers (USACE). The USACE is currently evaluating the AJD. Appropriate best
management practices (BMPs) and retention basins would be included in the Project design and
construction to minimize impacts to surface water runoff.
A Class I Cultural Resources Inventory consisting of a literature review and site files review was completed
for the site and was submitted as part of CPA2020002 (May 29, 2020). Two additional Class I Cultural
Resource Inventories were done in May 2022 (as part of the gen-tie Certificate of Environmental
Compatibility (CEC)) and in August 2022 for the current array footprint. Known archeological sites would be
avoided. Further, the Applicant is in consultation with the Arizona State Historic Preservation (SHPO)
regarding comments received on June 24, 2020. The SHPO provided further recommendation on October
5, 2022, due to the changes in Project acreage. In response to SHPO’s recommendations, the Applicant will
conduct a Class II sample survey on 25% of the Project site. Areas without prior survey or without survey
that meet modern standards were included in a Class III survey conducted by WestLand in April 2022. A
Class II Cultural Resources Sample Survey pursuant to the Arizona Antiquities Act (AAA) would be conducted
on the Project after zoning has been completed, but before construction of the Project. Additionally, the
State of Arizona requires that the inadvertent discovery, during construction, of human remains and
funerary objects be reported to the Director of the Arizona State Museum (ARS §41-865) upon discovery.
The Project would not significantly impact the scenic quality of the area. Currently there is electrical
infrastructure (e.g., transmission lines, solar electrical generating facilities, electrical substations) as well as
above-ground electrical distribution lines and transportation networks within the Project area and the
region. Existing views from within the site would not be significantly obscured, because the height of panels
would not obscure scenic views beyond the site. We have also previously submitted a glint/glare assessment
as part of CPA 2020002 (May 29, 2020) that shows that reflections from the solar array along existing roads,
at two airfields and at residences would not be adverse. The Applicant understands that the County will
require an 80% opacity screen be constructed in areas adjacent to existing residences to minimize visual
impact.
The Project has also sought to maintain compliance with requirements set by the Arizona Corporation
Commission (ACC). In 2022, the Project applied for a CEC from the ACC for the 500kV gen-tie that will
connect the Project switchyard to Delaney Substation. A public hearing by the Line Siting Committee on
October 24 and 25, 2022, took place where three alternate routes were agreed upon. The CEC was
subsequently granted by the ACC in Decision number 78809 on December 15, 2022. The Project is
committed to continue stakeholder and agency conversations through agency consultation and public
comment solicitation to minimize potential impacts of the Project.

PART D - WHETHER THE AMENDMENT IS CONSISTENT WITH THE OVERALL INTENT OF THE
COMPREHENSIVE PLAN.
The resolution adopting the County’s Vision 2030 Comprehensive Plan notes that the Comprehensive Plan
“helps to promote economic prosperity, maintain a vibrant quality of life, and facilitate continued growth in
a coordinated, harmonious, and responsible manner.” Further, the Comprehensive Plan outlines Strategic
Priorities for Maricopa County including “innovatively leverage its resources” and “deploy an effective and
efficient infrastructure.” The Project displays consistency with these priorities and the County’s vision to
work collaboratively and effectively for its residents, as detailed below.
Arizona is a prime location for the generation of solar electricity for both local consumption and export. The
Project, as a utility-scale renewable energy generation and storage facility, is in direct alignment with the
County’s mission and guiding principles for leadership and strategic priorities to leverage its resources to
provide for a balanced regional economy. Construction of the Project would contribute to local, County,
and state economic prosperity by providing employment opportunities for numerous experienced
professionals throughout construction. Additionally, spending for construction activities and workers would
also provide revenue opportunities to local businesses and the tax revenue from the Project would benefit
a wide variety of public services.
Meeting electric power demand with solar and storage projects such as this Project would contribute to an
effective and efficient infrastructure and improve quality of life locally in several ways. This Project would
contribute to improved air quality through reduced emissions as compared to traditional fossil fuel power
sources. As the cost of fossil fuels rises and aging fossil fuel power plants are retired, solar and storage
projects are an affordable and sustainable solution to help to meet the growing regional power demand.
Moreover, water conservation is becoming increasingly important as the country is experiencing historic
drought and reservoirs cannot recharge at the rates that they are being depleted. The Project would be a
low water use facility. Construction will utilize approximately 1,840-acre feet of water, while the O&M
building will utilize approximately 61-acre feet per year. The Project will require approximately 985 gallons
of potable water per month. The Project does not require water in the generation of electrical power and
requires very little water for panel and equipment maintenance. This Project would demonstrate responsible
environmental stewardship and would further the goal of increased water conservation within Maricopa
County.
One of the County’s core principles is to support implementation of the County’s strategic priorities. This
Project directly supports the County’s strategic priorities, as indicated in the discussion of the specific goals
and policies of the Comprehensive Plan in the following section.
5
PART E - THE EXTENT TO WHICH THE AMENDMENT IS CONSISTENT WITH THE SPECIFIC GOALS
AND POLICIES CONTAINED WITHIN THE PLAN.
Maricopa County places demonstrable value on alternative energy development, as evidenced by the
strategic priorities and core principles of the County’s Vision 2030 Comprehensive Plan. Maricopa County
explicitly identifies encouraging solar energy development as an important goal, particularly in Economic
Growth Policy 10, Energy Goal 2, Energy Policy 6, and Water Resources Policy 5 of the Vision 2030
Comprehensive Plan. The County’s strategy encouraging renewable energy development is provided as
follows:
CPA2023011Major Comprehensive Plan Amendment Application Project Narrative
Maricopa Energy Center Project

Page 9
Renewable Energy
Maricopa County has the potential to be a global leader in renewable energy research and
development, especially with respect to solar energy. Maricopa County is one of the most
productive spots in the world for both photovoltaic and concentrated solar energy generation.
Many companies have already discovered this potential, evidenced by the large number of
utility-scale plants being planned in unincorporated areas. Because of the economic and
environmental benefits Maricopa County supports state and local efforts to attract solar
research and development to this region.
Strategies - Attract solar and other alternative energy research and development to Maricopa
County.
The Project, a utility-scale renewable energy facility, is in direct alignment with the County’s strategy to
support the development of solar electrical generation.
The Project would use photovoltaic and battery technology and would require very little water use during
operations, apart from as-needed maintenance for cleaning the solar panels and equipment and water use
associated with the O&M building. Maricopa County recognizes the potential environmental and economic
benefits of solar developments within the Comprehensive Plan, as indicated by multiple goals and policies,
which are highlighted in Table 2.
The Applicant believes the Project is well suited for an agricultural area, because it requires large amounts
of relatively flat land. Further, proximity to the APS Delaney Substation that provides access to the Palo
Verde Nuclear Generating Station makes this location ideal in terms of minimizing the very long electrical
interconnects required for the transmission of electricity to the regional electrical grid. Moreover, the area
surrounding the APS Delaney Substation, as well as most of the land between the solar array and the APS
Delaney Substation, which lies 5.5 miles to the east, is mostly undeveloped.
It is recognized that small pockets of residential land use occur mostly south of the solar array, although
there are also a few residences east of the Project. The existing visual setting has been previously impacted
by agricultural farms and their attendant infrastructure (e.g., water pumps, retention basins, canals, farm
roads, and distribution lines); electrical infrastructure including the Harquahala Power Plant, high voltage
transmission lines, and electrical substations; flood control structures; and the transportation network (e.g.,
arterial roads and Interstate 10).
The Project would contribute to the existing visual clutter within the region; however, given the low-profile
design of the array, BESS, O&M building, and other ancillary facilities, it is not expected to adversely impact
existing views or the existing natural/man-made setting. The most prominent feature on the landscape
would be the Project’s 500kV interconnect, which would be constructed on structures approximately 135 to
200 feet tall and would be visible. However, this interconnect would occur, in part, in an area that already
has a 500kV transmission line present (i.e., from the Harquahala Power Plant to Delaney Substation).
Finally, the Applicant believes that this Project would assist the County in promoting its goal to encourage
solar development and the creation of jobs (both temporary construction jobs and permanent O&M jobs)
associated with these types of development. The Applicant believes the Project is wholly consistent with
specific goals and policies within Maricopa County’s Comprehensive Plan. At this early stage of planning,

estimated revenue to the County has not been calculated; however, as reflected above within the excerpted
statement from the County Comprehensive Plan (Vision 2030 Comprehensive Plan), the County recognizes
these Projects are economically beneficial.

RE:
Maricopa Energy Center Major Comprehensive Plan Amendment (CPA2023011)
Dear Mr. Schlimm:
The Arizona Game and Fish Department (Department) appreciates the opportunity to review the
proposed Maricopa Energy Center project. The Department understands that Maricopa Energy
Center, LLC proposes to construct a 550 MW photovoltaic (PV) solar facility with a battery
energy storage system (BESS) and associated infrastructure on approximately 4,265 acres of
private lands near Tonopah in Maricopa County, Arizona. The facility will be located northwest
of Saddle Mountain, south of the Big Horn Mountains Wilderness Area, and northeast of the
Eagletail Mountains Wilderness Area within the Harquahala Valley in a combination of
undeveloped sonoran desert scrub habitat and lands previously used for agriculture. An
approximately 5.2-mile single circuit 500kV generation intertie (gen-tie) transmission line would
connect the facility to the Arizona Public Service (APS) Delaney Substation.
Under Title 17 of the Arizona Revised Statutes, the Department, by and through the Arizona
Game and Fish Commission, has jurisdictional authority and public trust responsibilities to
conserve and protect the state fish and wildlife resources. In addition, the Department manages
threatened and endangered species through authorities of Section 6 of the Endangered Species
Act and the Department’s Section 10(a)(1)(A) permit. 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.
The Department recognizes the importance of planning efforts to develop renewable energy
locations that contribute to regional and state economic growth needs and would like to work
closely with Wood, Maricopa Energy Center, LLC, and Maricopa County during the planning
and development of this facility. The Department recognizes that appropriate coordination,
proper planning, and voluntary implementation of best management practices allow projects to
be developed that avoid, minimize, or offset potential impacts to wildlife and recreational access
during development and operation of the facilities. For your consideration, the Department
AZGFD – Maricopa Energy Center
July 12, 2023
Page 2
provides the following comments based on the agency's statutory authorities, public trust
responsibilities, and special expertise related to wildlife resources and recreation.
Arizona has recently seen an increase in the number of proposed and in-development renewable
energy generation projects and associated infrastructure. A number of solar projects have been
built or proposed within the vicinity of this project. Although each of these projects individually
may have a minimal impact on the broader landscape, these projects cumulatively could result in
loss of habitat, impact wildlife movements, and affect wildlife-related recreation. Additionally,
long-term effects to wildlife can extend several kilometers beyond the footprint of a solar project
area (Sawyer et al. 2022 ). It is important to consider all potential cumulative effects and to
1
evaluate this project in association with other projects in the area. Department staff are available
to assist in identifying potential cumulative impacts to wildlife and associated voluntary
conservation measures that can be implemented for the project.
The Department recommends conducting surveys in the project area to determine wildlife
species presence. These surveys should be of sufficient duration and intensity to adequately
assess all habitat types and potential species occurrence in and adjacent to the project area.
Department staff are available to assist Wood and Maricopa Energy Center, LLC in determining
appropriate surveys to conduct and design features and best management practices to implement
that can help minimize potential impacts. Based on the information provided, the Department
offers the following recommendations to reduce potential impacts to wildlife and habitat;
additional information can be found in Guidelines for Solar Development in Arizona :
2
●
The endangered Sonoran pronghorn could occur in the project area and adjacent lands.
Sonoran pronghorn have specific habitat requirements based on their life history and
survival strategy. The Department would like to work with Wood and Maricopa Energy
Center, LLC to minimize any potential impacts to this species. The Department
recommends scheduling construction activities outside the fawning season for Sonoran
pronghorn (February 1 to July 15) and requests coordination prior to construction
activities in order to exchange information on current Sonoran pronghorn use in the
project area. If pronghorn are detected during project activities, please notify the U.S.
Fish and Wildlife Service (USFWS) and the Department’s Sonoran Pronghorn Program
3
Lead (jbright@azgfd.gov) as soon as possible.
●
The Sonoran desert tortoise, which is a federal and state species of special concern, has
been documented within 5 miles of the project area. The Department recommends
conducting surveys, in accordance with the Desert Tortoise Survey Guidelines for
Environmental Consultants , to determine the presence of this species or its habitat. If
4
tortoises are identified, please refer to and implement the Recommended Standard

●
The western burrowing owl, a special status species that is regulated under the Migratory
Bird Treaty Act (MBTA), has the potential to occur in the project area. The Department
recommends conducting occupancy surveys for this species in advance of the design
phase to understand distribution of burrowing owls in the project site; avoidance of a
large burrowing owl population may be advisable over removal or other conservation
measures. Guidelines for conducting this survey are found in Burrowing Owl Project
Clearance Guidance for Landowners . Please note that the survey should be conducted
7
by a surveyor who is certified by the Department or has similar training and
qualifications. If an active burrowing owl burrow is detected, please contact the
Department and the USFWS for direction, in accordance with the guidelines.
●
Golden eagles, which are regulated under the Bald and Golden Eagle Protection Act
(BGEPA), could occur within the project vicinity. If uncertain about the effects of the
project on eagles, or if it is anticipated the project will not be in compliance with the
BGEPA, the Department recommends contacting the USFWS for technical assistance.
Additionally,
Tuk
Jacobson,
the
Department’s
eagle
specialist
is
available
at
raptors@azgfd.gov or 623-236-7575 to provide assistance and discuss conservation
measures to avoid or minimize potential effects on eagles.
●
Large-scale solar PV facilities can result in a high rate of bird mortality due to habitat
loss, collision with panels, attraction due to an optical illusion of water, and unknown
causes (Kosciuch et al. 2020 ). The Department recommends conducting avian surveys
8
during the planning stage in order to better understand species presence and to inform
potential conservation measures. Point counts are the preferred method for breeding bird
surveys. These surveys are conducted twice a year during the peak breeding season,
which is mid-January through June in this area; McLaren et al. (2019) outline protocols.
9
Additional surveys for Bendire’s and LeConte’s thrashers, two bird species of
conservation concern, are recommended; a draft protocol
from the Desert Thrashers
10
Working Group is available online.
●
The Department also recommends conducting surveys for nesting birds prior to
vegetation removal and/or construction activities that occur during the breeding season.
The vegetation within the project area may provide nesting opportunities for avian
species that are regulated under the Migratory Bird Treaty Act (MBTA). It is
recommended to avoid activities in the vicinity of any occupied nests within the project
area that could disturb or cause the nest to fail until after fledging has occurred. If it is
anticipated the project will not be in compliance with MBTA, the Department
recommends contacting the USFWS for technical assistance.

●
Burrowing mammal species could occur within the project area and could be influenced
by construction activities and by loss of habitat. Surveys for these species are
recommended to determine their presence and to inform pre-construction activities.
Department staff are available to assist in identifying suitable conservation measures,
such as one-way exclosures on burrows that allow wildlife to exit the burrows and
disperse to adjacent lands in advance of construction.
●
A variety of other Arizona Species of Greatest Conservation Need (SGCN) have the
potential to occur within the project area. If wildlife are encountered during project
activities, the Department recommends moving them out of harm’s way, no more than
0.25 mile outside the project boundary within similar habitat. Please note that the Arizona
State Wildlife Action Plan was recently updated, and the Department has an interactive
website, Arizona Wildlife Conservation Strategy , that includes the most recent list of
11
SGCN to help navigate and identify conservation opportunities.
Maintaining habitat connectivity is a priority for the Department, and wildlife movement
corridors are important for wildlife to respond to changing environmental conditions. The
landscape in which this project is proposed provides important movement pathways for wildlife
and, as identified in the attached Heritage Data Management System (HDMS) Online
Environmental Review Tool (ERT) report (HGIS-19602), this project falls within two county
stakeholder identified wildlife movement areas. The Department would like to meet with Wood
and Maricopa Energy Center, LLC to discuss opportunities to incorporate wildlife connectivity
into the project design, including the following:
●
The Department recommends incorporating project design features to facilitate wildlife
movement within the project area. These include open unfenced wildlife movement
corridors, including within upland habitat, as well as maintaining the ephemeral washes
that occur in the project area in their natural state without fencing or other barriers to
wildlife movement. These washes serve multiple functions in the ecosystem. Not only do
they provide for hydrologic flow, which is especially important in areas that receive
infrequent and isolated precipitation events, but these washes also serve as important
landscape-level conveyance corridors for wildlife movement.
●
The Department recommends conducting minimal grading in the project area and, to the
extent possible, retaining habitat features underneath the panels, including vegetation and
soils. The topography in the majority of the site is flat and would require minimal
trimming of shrubs and existing vegetation to install the panels. Keeping the existing soil
and root structures intact would serve to minimize erosional run-off and help reduce
biodiversity loss within the site (Grodsky and Hernandez 2020 ).
12
●
The Department’s Wildlife Compatible Fencing Guidelines
provide information on how
13
fencing impacts wildlife, ways to design fencing to prevent wildlife entanglement and
impalement, and to ensure wildlife movement is not restricted. Department personnel are
available as resources to help determine appropriate fencing design and layout that will

achieve its objective while reducing impact on wildlife, such as leaving a 6–8-inch gap
between the ground surface and bottom of the fence to allow for smaller wildlife species
to move freely through the area and make use of any habitat within the project boundary.
Finally, the Department offers the following general recommendations to reduce potential
impacts to wildlife and habitat during construction and operation of the facility:
●
Because proposed ground disturbance (both temporary and permanent) will exceed 0.25
acres in areas with native vegetation, please ensure the project complies with the Arizona
Native Plant Law regulations . A Native Plant Inventory may need to be conducted to
14
identify, record, and coordinate plant salvage efforts for species that are protected under
the Arizona Native Plant Law.
●
To minimize the potential introduction or spread of exotic invasive species, including
aquatic and terrestrial plants, animals, insects, and pathogens, the Department encourages
taking precautions to wash and/or decontaminate equipment before entering and leaving
the site. See the Arizona Department of Agriculture website
for a list of prohibited and
15
restricted noxious weeds and the Arizona Native Plant Society
for recommendations on
16
how to control them. To view a list of documented invasive species or to report invasive
species in or near the project area, visit iMapInvasives , which is a national cloud-based
17
application for tracking and managing invasive species.
●
If trenching or digging of large holes necessary for anchoring project infrastructure will
occur for the proposed project, the Department recommends trenching/digging and
backfilling crews be close together to minimize the amount of open holes at any given
time. Where trenches or holes cannot be back-filled immediately, the Department
recommends escape ramps be constructed at least every 90 meters. Escape ramps can be
short lateral trenches or wooden planks sloping to the surface. The Department
recommends that slopes be less than 45 degrees (1:1) and trenches and holes that have
been left open be inspected to remove animals prior to backfilling.
●
The Department recommends following standards established by the Avian Power Line
Interaction Committee (APLIC) for new powerlines, which can be found in Suggested
Practices for Avian Protection on Power Lines: The State of the Art in 2006
and
18
Reduced Avian Collisions with Power Lines: The State of the Art in 2012 . Birds of prey,
19
such as raptors, owls, vultures, and eagles, are vulnerable to powerline strikes and
electrocution during construction and operation of transmission lines; power poles can
also serve as perches for birds of prey. Tuk Jacobson, the Department’s Raptor
Coordinator, can provide further information on specific design features and best
management practices; he can be contacted at raptors@azgfd.gov or 623-236-7575.
●
The Department recommends revegetating disturbed areas with native drought-tolerant
species that represent the natural surrounding landscape. Landscaping with native plants

can help support wildlife and pollinator species in the area while reducing dust and
erosion. In addition, the applicable land management agencies should be consulted
regarding guidelines for revegetation efforts.
●
Artificial lighting could impair the ability of nocturnal animals to navigate (e.g., owls,
migratory birds, bats, and other nocturnal mammals) and may affect wildlife behavior
and populations (Davies et. al. 2013 ). The Department recommends using only the
20
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.
Thank you for the opportunity to provide input on the Maricopa Energy Center. For further
coordination, please contact Teigan Williams at tstruck@azgfd.gov or (928) 341-4069.
Sincerely,
Michael Sumner

Review Date: 6/22/2023 04:07:45 PM
Disclaimer:
1. This Environmental Review is based on the project study area that was entered. The report must be
updated if the project study area, location, or the type of project changes.
2. This is a preliminary environmental screening tool. It is not a substitute for the potential knowledge
gained by having a biologist conduct a field survey of the project area. This review is also not intended to
replace environmental consultation (including federal consultation under the Endangered Species Act),
land use permitting, or the Departments review of site-specific projects.
3. The Departments Heritage Data Management System (HDMS) data is not intended to include potential
distribution of special status species. Arizona is large and diverse with plants, animals, and
environmental conditions that are ever changing. Consequently, many areas may contain species that
biologists do not know about or species previously noted in a particular area may no longer occur there.
HDMS data contains information about species occurrences that have actually been reported to the
Department. Not all of Arizona has been surveyed for special status species, and surveys that have been
conducted have varied greatly in scope and intensity. Such surveys may reveal previously
undocumented population of species of special concern.
4. Arizona Wildlife Conservation Strategy (AWCS), specifically Species of Greatest Conservation Need
(SGCN), represent potential species distribution models for the State of Arizona which are subject to
ongoing change, modification and refinement. The status of a wildlife resource can change quickly, and
the availability of new data will necessitate a refined assessment.
Locations Accuracy Disclaimer:
Project locations are assumed to be both precise and accurate for the purposes of environmental review. The
creator/owner of the Project Review Report is solely responsible for the project location and thus the correctness
of the Project Review Report content.

Recommendations Disclaimer:
1. The Department is interested in the conservation of all fish and wildlife resources, including those
species listed in this report and those that may have not been documented within the project vicinity as
well as other game and nongame wildlife.
2. Recommendations have been made by the Department, under authority of Arizona Revised Statutes
Title 5 (Amusements and Sports), 17 (Game and Fish), and 28 (Transportation).
3. Potential impacts to fish and wildlife resources may be minimized or avoided by the recommendations
generated from information submitted for your proposed project. These recommendations are preliminary
in scope, designed to provide early considerations on all species of wildlife.
4. Making this information directly available does not substitute for the Department's review of project
proposals, and should not decrease our opportunity to review and evaluate additional project information
and/or new project proposals.
5. Further coordination with the Department requires the submittal of this Environmental Review Report with
a cover letter and project plans or documentation that includes project narrative, acreage to be impacted,
how construction or project activity(s) are to be accomplished, and project locality information (including

Project Type Recommendations:
During the planning stages of your project, please consider the local or regional needs of wildlife in regards to movement,
connectivity, and access to habitat needs. Loss of this permeability prevents wildlife from accessing resources, finding
mates, reduces gene flow, prevents wildlife from re-colonizing areas where local extirpations may have occurred, and
ultimately prevents wildlife from contributing to ecosystem functions, such as pollination, seed dispersal, control of prey
numbers, and resistance to invasive species. In many cases, streams and washes provide natural movement corridors
for wildlife and should be maintained in their natural state. Uplands also support a large diversity of species, and should
be contained within important wildlife movement corridors. In addition, maintaining biodiversity and ecosystem functions
can be facilitated through improving designs of structures, fences, roadways, and culverts to promote passage for a
variety of wildlife. Guidelines for many of these can be found
at: https://www.azgfd.com/wildlife/planning/wildlifeguidelines/.
Consider impacts of outdoor lighting on wildlife and develop measures or alternatives that can be taken to increase
human safety while minimizing potential impacts to wildlife. Conduct wildlife surveys to determine species within project
area, and evaluate proposed activities based on species biology and natural history to determine if artificial lighting may
disrupt behavior patterns or habitat use. Use only the minimum amount of light needed for safety. Narrow spectrum bulbs
should be used as often as possible to lower the range of species affected by lighting. All lighting should be shielded,
canted, or cut to ensure that light reaches only areas needing illumination.
Minimize the potential introduction or spread of exotic invasive species, including aquatic and terrestrial plants, animals,
insects and pathogens. Precautions should be taken to wash and/or decontaminate all equipment utilized in the project
activities before entering and leaving the site. See the Arizona Department of Agriculture website for a list of prohibited
and restricted noxious weeds at https://www.invasivespeciesinfo.gov/unitedstates/az.shtml and the Arizona Native Plant
Society https://aznps.com/invas for recommendations on how to control. To view a list of documented invasive species or
to report invasive species in or near your project area visit iMapInvasives - a national cloud-based application for tracking
and managing invasive species at https://imap.natureserve.org/imap/services/page/map.html.
To build a list: zoom to your area of interest, use the identify/measure tool to draw a polygon around your area of
interest, and select “See What’s Here” for a list of reported species. To export the list, you must have an
account and be logged in. You can then use the export tool to draw a boundary and export the records in a csv
file.
Minimization and mitigation of impacts to wildlife and fish species due to changes in water quality, quantity, chemistry,
temperature, and alteration to flow regimes (timing, magnitude, duration, and frequency of floods) should be evaluated.
Minimize impacts to springs, in-stream flow, and consider irrigation improvements to decrease water use. If dredging is a
project component, consider timing of the project in order to minimize impacts to spawning fish and other aquatic species
(include spawning seasons), and to reduce spread of exotic invasive species. We recommend early direct coordination
with Project Evaluation Program for projects that could impact water resources, wetlands, streams, springs, and/or
riparian habitats.
The Department recommends that wildlife surveys are conducted to determine if noise-sensitive species occur within the
project area. Avoidance or minimization measures could include conducting project activities outside of breeding
seasons.

Review Date: 6/22/2023 04:07:45 PM
For any powerlines built, proper design and construction of the transmission line is necessary to prevent or minimize risk
of electrocution of raptors, owls, vultures, and golden or bald eagles, which are protected under state and federal laws.
Limit project activities during the breeding season for birds, generally March through late August, depending on species
in the local area (raptors breed in early February through May). Conduct avian surveys to determine bird species that
may be utilizing the area and develop a plan to avoid disturbance during the nesting season. For underground
powerlines, trenches should be covered or back-filled as soon as possible. Incorporate escape ramps in ditches or
fencing along the perimeter to deter small mammals and herpetofauna (snakes, lizards, tortoise) from entering ditches. In
addition, indirect affects to wildlife due to construction (timing of activity, clearing of rights-of-way, associated bridges and
culverts, affects to wetlands, fences) should also be considered and mitigated.
Based on the project type entered, coordination with State Historic Preservation Office may be required
(https://azstateparks.com/).
Based on the project type entered, coordination with U.S. Fish and Wildlife Service (Migratory Bird Treaty Act) may be
required (https://www.fws.gov/office/arizona-ecological-services).
Vegetation restoration projects (including treatments of invasive or exotic species) should have a completed site-
evaluation plan (identifying environmental conditions necessary to re-establish native vegetation), a revegetation plan
(species, density, method of establishment), a short and long-term monitoring plan, including adaptive management
guidelines to address needs for replacement vegetation.
The Department requests further coordination to provide project/species specific recommendations, please
contact Project Evaluation Program directly at PEP@azgfd.gov.
Project Location and/or Species Recommendations:
Analysis indicates that your project is located in the vicinity of an identified Conservation Opportunity Area (COA). While
there are many areas in Arizona that present abundant conservation opportunities, COAs are specific areas on the
landscape that the Department identified as having the greatest potential for conservation efforts. COAs were identified
using species and habitat data, the presence of unique landscape features, and Departmental expertise. COAs range in
size, scope, and focal species and/or habitats and are strictly a non-regulatory conservation tool for the public and our
conservation partners to consider. For more information regarding this particular COA near your project area and the
Department's suggestions for potential conservation efforts, please visit the COA profile at
https://awcs.azgfd.com/conservation-opportunity-areas.
Analysis indicates that your project is located in the vicinity of an identified wildlife habitat connectivity feature. The
County-level Stakeholder Assessments contain five categories of data (Barrier/Development, Wildlife Crossing Area,
Wildlife Movement Area- Diffuse, Wildlife movement Area- Landscape, Wildlife Movement Area- Riparian/Washes) that
provide a context of select anthropogenic barriers, and potential connectivity. The reports provide recommendations for
opportunities to preserve or enhance permeability. Project planning and implementation efforts should focus on
maintaining and improving opportunities for wildlife permeability. For information pertaining to the linkage assessment
and wildlife species that may be affected, please refer
to: https://www.azgfd.com/wildlife/planning/habitatconnectivity/identifying-corridors/.
Please contact the Project Evaluation Program (pep@azgfd.gov) for specific project recommendations.

She will be able to give you the details of how and where to place your off-site improvements (Salome Highway paving)
that we discussed in this week's earlier meeting. She is the Development- Branch Manager DOT - Transportation
Systems Management and Operations (TSMO).
She will be your point of contact as I have worked with her for other solar projects in the area. Bonnie would probably
be working on the future projects as well making sure improvements are done to the region and costs are spread out
across all developments.
If there is anything else you need from ADOT you all have my contact info. Have a great weekend!

Richard,
ADOT has received your Major Comprehensive Plan Amendment Application via Maricopa County for the subject
project.
Overall this land looks good for solar use and access off Interstate 10 is common.
Traffic issues to keep in mind is that ADOT has recently worked with an additional solar facility that will repair and
widen the asphalt at the Harquahala Valley/Salome HighwayTraffic Interchange. This project should continue their
improvements, paving and widening Salome Highway Road along the unpaved sections of roadway between I-10 and
Courthouse Road. Length to be determined by Maricopa County (Owner).
Contact myself and Gerry Rameriaz for ADOT Permits and Specifications. (grameriaz@azdot.gov)

RE: CPA2023011 - Technical Advisory Committee (TAC) Notification
Good morning Mr. Schlimm,
I apologize for the delayed response on this proposed development. We worked with the applicant to obtain a .KMZ file
with all the proposed tie-in locations and then plotted them under our military training routes and low-flying routes.
Thank you for the opportunity to comment on the Major Comprehensive Plan Amendment Application to change the
land use designation from Rural to Utilities in order to develop and operate a solar generating facility. In addition to
photovoltaic solar, this proposed project would also include a Battery Energy Storage System (BESS). The site contains
approximately 1,150 acres to be added to previously approved acreage for a combined area of 4,265 acres. Ultimately,
the project will contain 160-180ft structures for a connection to a 5.2-mile 500kV transmission line. The proposed site is
located approximately 12 miles west of Tonopah, at Harquahala Valley Road and Camelback Road in unincorporated

As currently proposed, the site is located outside of low-flight corridors and does not impact the flying operations of
Luke AFB. However, please ensure the project is submitted for an informal review through the DoD Siting Clearinghouse
for Energy, Installations, and Environment. Please send the project narrative for review to: osd.dod-siting-
clearinghouse@mail.mil. This response is conditional upon their approval/input.

CPA2023011: Major Comprehensive Plan Amendment – Maricopa Energy Center
CPA2023012: Major Comprehensive Plan Amendment – Belmont Mixed Use
CPA2023013: Major Comprehensive Plan Amendment – Desert Gem Solar Project
Dear Mr. Mueller, Mr. Lorentzen, and Mr. Schlimm:
Thank you for the opportunity to review and comment on Maricopa County Major Comprehensive
Plan Amendments CPA2023011, CPA2023012 and CPA2023013 for solar energy projects and
a mixed use in the county, to change land use designations from Rural Residential to Utilities on
± 2,000 acres and ± 9,300 acres, respectively, for large-scale solar farm and battery storage
systems.
The Maricopa Energy Center major comprehensive plan amendment area is located generally
south of Interstate 10, about halfway between the City of Phoenix and the Arizona/California
boundary.
The Desert Gem Solar project is located about midway between I-8 and I-10 on the west side of
State Highway 85, about 15 miles south of the Town of Buckeye and 20 miles north of Gila Bend.
The proposed solar energy generation and storage projects are located in regions of high solar
exposure, proximity to other existing solar energy farms and adequate energy transmission
infrastructure. Projects should have minimal impact on surrounding properties and generation of
renewable energy would be a benefit to the region. In addition, the project will be retiring
agricultural land and reducing associated water use and increasing regional renewable energy.
The Belmont Mixed Use major comprehensive plan amendment area is located generally north
of Interstate 10, about 40 miles west of central Phoenix. This proposed amendment will contribute
to the economic development and exposed tourism opportunity in the region.
Pima County Development Services Department, Planning Division has no opposition to the
proposed major comprehensive plan amendments.
Sincerely,
Aaron Reid
Planning Intern

Good afternoon Bill,
Since Case CPA2023011 is a request for a major Comprehensive Plan Amendment, only the land use
designation in the Maricopa County Comprehensive Plan will change (from Rural Development Area to
Utilities) following approval of the case by the Board of Supervisors. There is no zone change request
currently under review for the parcels subject to CPA2023011. The applicant does intend to submit a
request for a zone change with overlay (to IND-2 IUPD) after BOS approval of CPA2023011.
On that note, I will advise that CPA2023011 is scheduled to be heard by the Planning & Zoning
Commission on Thursday, November 2nd, after which it will be heard by the Board of Supervisors on
Wednesday, December 6th. Because the enhanced routing for the case has already been completed, and
the legal ad for the case has already been published, the Planning & Development Department is unable
to incorporate any additional parcels or land as part of this case.
However, if you are interested in incorporating your parcel into the Maricopa Energy Center project area
in the future, you are certainly welcome to contact the applicant and discuss options with them. Richard
Knox is the applicant’s point of contact for this case… you are welcome to reach him at
richard.knox@woodplc.com. You may also visit the project website, which provides contact information
for the project: https://maricopaenergycenter.com/2023-mcpa.
I hope this helps. If you have any further questions or concerns regarding CPA2023011, please feel free
to contact me.
Sincerely,
Nick Schlimm

Hi Nicholas:
I am the manager of CBTN Land Holdings, LLC and it appears we are within 300 ft of this project.
We wonder if;
1. What are our options as it relates to this CPA
1. CAN We be added to the the parcels to be re-zoned?
2. CAN We Be rezoned as an industrial parcel?
3. What can we do?
Sincerely,
Bill Seneff
