The 
applicant 
seeks 
a 
Major 
Comprehensive 
Plan 
Amendment to change the land use designation in the 
Comprehensive Plan to utilities in order to develop a solar 
installation. The subject site is identified as having Rural 
Development Area land use designation in the Vision 2030 
Maricopa County Comprehensive Plan. All approx. 1,997 
acres are designated as Rural Development Area (0-1 
d.u./acre).  This designation encourages low-density rural 
residential and agricultural uses.  Staff received three (3) 
letters from adjacent/internal jurisdictions (Town of Carefree, 
Yavapai County, Pima County) expressing no concerns.  AZ 
Dept. of Game & Fish commented on the site regarding 
wildlife and hydrology.  AZSHPO and AZAG had no concerns.  
Luke Air Force Base requested that the applicant complete 
the DOD Siting Clearinghouse review.  The applicant did 
contact the DOD and the DOD indicated concerns with the 
usage of cranes at the time of construction may impact flying 
operations.  The applicant agreed to comply with any 
comments received by the DOD and the comments will be 
considered during a future zone change request.  Staff 
received no opposition to this case.

Recommendation: 
On 11/3/22, the Commission voted 9-0 to recommend 
approval of CPA2022009 subject to conditions ‘a’ – ‘d’: 
  
a. 
Development and use of the site shall be in substantial conformance with the 
narrative report entitled “Hyder Energy Center Project” dated revised September 
30, 2022 and stamped received October 3, 2022, except as modified by the 
following conditions.  
 
b. 
Development and use of the site shall be in substantial conformance with the land 
use exhibit entitled “Land Use Exhibit” dated revised September 30, 2022 and 
stamped received October 3, 2022, except as modified by the following 
conditions. 
 
c. 
The land use designation of ‘Utilities’ approved as part of case CPA2022009 shall 
be subject to any applicable time limits set forth in the subsequent zone change. 
  
d. 
The applicant is proposing to develop a photovoltaic solar electric generating 
facility which, pursuant to the Maricopa County Comprehensive Plan, 
necessitates a change in the land use designation from Rural Development Area 
to Utilities. The proposal by the applicant represents a comprehensive approach 
to the subject property and will allow the applicant to pursue the proper 
entitlements pursuant to state law so that they can lawfully operate in 
unincorporated Maricopa County. This particular proposal is an appropriate plan 
for the property and is consistent with the overall intention of the comprehensive 
plan. However, in the event that the zone change or a zone change phase for this 
particular proposal is not approved by Maricopa County Board of Supervisors 
(BOS) within five (5) years from the date of Board approval of this comprehensive 
plan amendment, this amendment shall no longer be effective as the planning 
justification for this comprehensive plan amendment will no longer be present. In 
such instance, a change of the land use designation from Utilities to Rural 
Development Area will occur, and all comprehensive plan land use maps shall be 
altered to reflect as such, because this represents superior long-range planning by 
Maricopa County.

Project Summary: 
 
1. 
Wood Environment & Infrastructure Solutions, 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 phased 
development of a utility-scale solar electric generating project. This site represents Phase 
2 of a larger site in which Phase 1 received a Major CPA for approx. 3,619 acres in 2021.  
Together, both phases would generate approximately 800 megawatts (MWs) of 
electricity along with a battery energy system storing and discharging up to 3.2 gigawatt 
hours.  Due to the size of the project at 1,997 acres, a Major CPA is required. The applicant 
will subsequently be required to obtain a Zone Change with Overlay (including a precise 
Plan of Development) to IND-2 IUPD as part of the entitlement process within five (5) years 
(on a phase or for the entirety of the development).  
 
2. 
The site is comprised of thirty-seven (37) private parcels in five non-contiguous areas.  
Most properties in the immediate vicinity of the project are privately owned and nearby 
the small, sparsely populated town of Hyder, AZ which once served as a rail outpost and 
training area for the military during World War II.  The applicant’s narrative states that site 
control options are secured for all of the parcels.   
 
3. 
Nearly all land used for solar energy projects are developed for the large fields of solar 
collectors that capture the energy through photovoltaic technology. While a majority of 
the topography is flat and allows for the development of solar energy with little or no 
additional grading, there are a number of elevated areas particularly along the southern 
boundary of the site where the Agua Caliente Mountains reside which are expected to 
naturally screen the site.   Development of the hillside areas is not expected as hillside 
areas are generally unsuitable for panel placement. This matter will be addressed more 
thoroughly in a potential Zone Change and Plan of Development application. A majority 
of the site is vacant, native desert land with some large agricultural parcels utilized for 
row crops.  The Gila River is located east of the site and various washes are present 
throughout the site.  In addition, the general area contains significant local electrical 
infrastructure including a battery energy storage facility in Yuma County.  The proposal is 
expected to include a substation to be utilized for the site. 
 
4. 
Adjacent land uses include vacant, agricultural, and very limited rural residential uses.  
There is also an inoperable railroad line controlled by Union Pacific.  Previous CPAs for the 
Verma Solar Project and the original Hyder Phase 1 were approved in 2021 adjacent to 
the site.  Within Yuma County there is a nearby APS battery storage farm and substation 
that the Hyder development is not expected to connect to. The project will connect to 
an interconnect line owned by San Diego Gas and Electric and controlled by the 
California Independent System Operator. 
 
5. 
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.

CPA2022009 
Page 3 of 11 
The narrative states that the Hyder Energy Center Project is an improvement to the 
Comprehensive Plan due to the benefits to the state, county, local and regional 
economy.  According to the narrative, a future solar and battery storage development 
will provide employment for approximately 250-350 construction employees per 18-24 
month construction phase for up to 5 construction phases.  The applicant will make efforts 
to hire individuals from the local area and region.  The narrative also states that the 
proposal is intended to support future electrical loads in the absence of coal and hydro 
generators (i.e. Lake Mead), to secure renewable and storable power for Arizona and 
the greater southwest and provide “reasonably priced” electricity to the regional grid. 
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/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, the amendment will not alter any surrounding land uses or land use 
patterns.  The land is currently vacant or agricultural.  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 in the vicinity of 
other utility uses in both Yuma and Maricopa Counties and comprises a key use-
sector of unincorporated Maricopa County including utilities (solar and electric 
generating stations), agriculture and rural-residential. 
 
B. 
Requiring public expenditures for larger or 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 developer. 
 
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 using on-site wells.  
Existing roads will serve the project and any additional project infrastructure needs 
shall be borne by the developer. 
 
D. 
Adversely impacting planned uses because of increased traffic – The narrative 
indicates there would be increased traffic during the five construction phases 
(approximately 18-24 months per phase) for the delivery of equipment / supplies 
and the commuting of the construction work force, but there would be no 
significant increase in traffic during the operational life of the project following the 
construction phase.  Access to existing uses within and around the site area would 
remain open to owners. 
 
E. 
Affecting the livability of the area or health or safety of present and future residents 
– During the construction period, 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.  Site screening 
would be required for screening for existing and future residential development

CPA2022009 
Page 4 of 11 
during the site.  Additionally, the project will follow federal, state and local 
regulations regarding the production, use, storage, transport or disposal of 
hazardous materials.  Wildlife prevention and mitigation measures will be 
incorporated into the Specific Plan of Development.  Fire hazard risks will be 
controlled 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 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 performed a field-site investigation and conducted pre-
construction wildlife surveys to identify habitats for creatures.  The Arizona Game 
and Fish Department (AZGFD) has commented on the proposed project 
regarding measures to protect wildlife encountered on the site such as the 
Sonoran Desert Tortoise, Sonoran Pronghorn, Kit Fox, Gila Monster, Lowland 
Leopard Frog, Western Burrowing Owl and Bald Eagle.  Satisfaction of those 
comments are only required at the Zone Change with Overlay stage (where a 
precise Plan of Development is required); however, Staff expects coordination to 
occur during the CPA process. The applicant demonstrated active coordination 
with AZGFD on wildlife protection measures as evidenced by the letter by AZGFD 
on September 28, 2022.   
 
Plants 
The applicant will salvage or dispose of protected native plants in accordance 
with AAC Title 3, Chapter 3, Article 11. 
 
 
Historical Resources 
A Class 1 and Class 3 Cultural Resources Inventory and Pedestrian Survey were 
completed and submitted to SHPO.  AZSHPO did not comment on the proposal. 
Satisfaction of SHPO comments is only required at the time of construction 
permitting.  Development will avoid any known archeological sites and any 
discovery of human remains or funerary objects will be reported to the Director of 
the Arizona State Museum upon discovery per state law. 
 
Scenic Views 
The narrative indicates that the height of panels and any screening from 
residential will not obscure scenic views. The applicant noted that screening from 
residential will be required to minimize the visual impact of the solar panels on 
residence owners.   
 
 
Hydrology/Ground Disturbance 
According to the narrative, hydrologic conditions will be preserved by avoiding 
the Gila River and any identified Waters of the United States and wetlands and in 
accordance with agency requirements.  AZGFD issued comments concerned

CPA2022009 
Page 5 of 11 
about on-site ephemeral washes and maintaining those washes to protect the 
riparian habitat.  The applicant will address retention in accordance with 
Maricopa County agency requirements at the zone change stage of the project.  
Grading will occur at appropriate slopes associated with the project and for other 
appropriate facilities.  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 by addressing the Strategic Priorities for Maricopa County such as 
innovatively leveraging its resources and deploying an effective and efficient 
infrastructure. The narrative also states that the proposal is in line with the adopting 
resolution stating the Plan “helps promote economic prosperity, maintain a vibrant 
quality of life and facilitate continued growth in a coordinated, harmonious and 
responsible manner”.  The applicant argues that this is demonstrated through the 
economic benefits provided in consumption and export of the product (solar energy), 
the hiring of workers and government revenue gained through the proposal.  In addition, 
the narrative asserts that the project contributes to an effective and efficient 
infrastructure and improve quality of life by functioning as a low water use facility 
demonstrating responsible environmental stewardship through the provision of 
renewable energy.   
 
The extent to which the amendment is consistent with the specific goals and policies 
contained within the plan. 
 
The applicant’s 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: 
 
9. 
Vision 2030 Maricopa County Comprehensive Plan: The entire site (approx. 1,997 acres) 
is designated as Rural Development Area (0-1 d.u./ac.).  The Rural Development Area 
land use designation encourages low-density rural residential and agricultural uses. 
 
Public Participation Summary: 
 
10. 
The applicant posted the subject site and staff notified all property owners within 300’ of 
the site.  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 (LAFB). Staff received three (3) letters from adjacent/internal 
jurisdictions (Town of Carefree, Yavapai County, Pima County) expressing no concerns.  
The Arizona Attorney General’s Office stated that there are no objections to the request.  
Comments received from Arizona Game & Fish Department (AZGFD) and associated 
responses by the applicant are included in the attachments section and are not 
actionable from the County’s perspective until the Zone Change and Plan of 
Development stage.  The Arizona State Historic Preservation Office (AZSHPO) 
commented that they received notice of the project, but did not issue written comments.  
Instead, they participated in the Technical Advisory Committee meeting and reminded 
the applicant of state law related to burial ground disturbance.  The applicant included 
correspondence between the applicant and the Tohono O’odham Nation regarding 
cultural and biological resources surveys; however, Staff did not receive any direct 
correspondence from the Nation. 
   
11. 
LAFB sent three comment letters to Staff asking the applicant to undergo informal review 
through the Department of Defense (DOD) Siting Clearinghouse for Energy, and 
acknowledge the applicant’s submission to the Clearinghouse.  LAFB also stated that a 
land use designation change would not affect flying operations, but that LAFB reserved 
the right to comment on future site plans received by the County.  In correspondence, 
the applicant demonstrated that they initiated and completed review through the 
Clearinghouse.  The Department of Defense determined that the proposal may impact 
flying operations.  When the applicant requested a clarification from the DOD, the 
agency clarified that it would like to be notified about construction dates and that their 
primary concern is with crane usage during construction.  These comments can be 
conditioned in the zone change and plan of development and are also comments that 
the applicant agreed to comply with.

CPA2022009

12. 
According to the Public Participation Results Report submitted by the applicant, the 
applicant conducted a virtual public meeting on September 14, 2022 which was 
advertised on three separate occasions in advance of the meeting in the Arizona 
Business Gazette.  There were 9 citizen attendees not including staff of the applicant.  The 
applicant received general questions related to infrastructure and technical details 
about energy generation.   
 
13. 
Additionally, the Public Participation Results Report included a record of all phone calls 
and their communications and facilitated virtual meeting accessibility for an out-of-state 
adjacent owner.  The majority of these communications were focused on property 
purchase/lease.  There were a couple of concerns about property values and screening.  
The remainder of these communications were information requests.  The applicant also 
developed a project website which included a questionnaire.  According to the report, 
the applicant received no replies to the questionnaire. 
 
14. 
County Staff received no opposition or support letters for the request.   
 
Outstanding Concerns from Reviewing Agencies: 
 
15. 
N/A 
 
Staff Analysis: 
 
16. 
The state and Maricopa County recognize the potential environmental and economic 
benefits that solar technology can provide.  The Hyder Energy Center Project will use 
photovoltaic technology that generates energy from sun absorption.  Photovoltaic 
technology differs from other techniques that required 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.  The battery storage 
component associated with this proposal assists with additional production and any 
concerns associated with fire will be resolved prior to any construction permit issuance. 
  
16. 
Staff believes the proposed solar facility is well suited to this rural area.  Solar facilities 
require large amounts of relatively flat land, and the vast majority of the subject site is 
flat.   Staff agrees with the applicant that the subject site is suitable due to relative 
proximity to electrical transmission lines, nearby stations and substations, and 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 has 
consulted on a number of occasions with AZGFD on wildlife preservation which is 
important to Staff as it demonstrates the responsibility associated with development large 
swaths of land within unincorporated Maricopa County.  Since the area is primarily 
undeveloped vacant land in near proximity to other existing utility-scale solar projects, 
staff believes there will be minimal impacts to the surrounding area. 
 
17. 
Promoting 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 Hyder Energy Center Project would add to this 
effort in a positive way by providing the potential for 250-350 temporary construction jobs

CPA2022009 
Page 10 of 11 
for up to 5 construction phases lasting approximately 18-24 months each.  There will also 
be small number of long-term employment opportunities for County residents.  
 
18. 
Staff believes the Hyder 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 and 
as governed by the recommended conditions, represent proper long-term land use 
planning in the region and for Maricopa County as a whole.   
 
Recommendation: 
 
19. 
For the reasons outlined in this report, staff recommends the Commission motion for 
Approval, subject to conditions ‘a’ – ‘d’. 
 
a. 
Development and use of the site shall be in substantial conformance with the 
narrative report entitled “Hyder Energy Center Project” dated revised September 
30, 2022 and stamped received October 3, 2022, except as modified by the 
following conditions.  
 
b. 
Development and use of the site shall be in substantial conformance with the land 
use exhibit entitled “Land Use Exhibit” dated revised September 30, 2022 and 
stamped received October 3, 2022, except as modified by the following 
conditions. 
 
c. 
The land use designation of ‘Utilities’ approved as part of case CPA2022009 shall 
be subject to any applicable time limits set forth in the subsequent zone change. 
  
d. 
The applicant is proposing to develop a photovoltaic solar electric generating 
facility which, pursuant to the Maricopa County Comprehensive Plan, 
necessitates a change in the land use designation from Rural Development Area 
to Utilities. The proposal by the applicant represents a comprehensive approach 
to the subject property and will allow the applicant to pursue the proper 
entitlements pursuant to state law so that they can lawfully operate in 
unincorporated Maricopa County. This particular proposal is an appropriate plan 
for the property and is consistent with the overall intention of the comprehensive 
plan. However, in the event that the zone change or a zone change phase for this 
particular proposal is not approved by Maricopa County Board of Supervisors 
(BOS) within five (5) years from the date of Board approval of this comprehensive 
plan amendment, this amendment shall no longer be effective as the planning 
justification for this comprehensive plan amendment will no longer be present. In 
such instance, a change of the land use designation from Utilities to Rural 
Development Area will occur, and all comprehensive plan land use maps shall be 
altered to reflect as such, because this represents superior long-range planning by 
Maricopa County.

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 Hyder Energy Center Project (the Project). Hyder Energy Center, LLC, as the applicant and Developer 
(the Developer), is proposing the construction and operation of an up to 800 megawatt alternating current 
(MWac) electrical generation facility consisting of solar modules and a battery energy storage system (BESS), 
collectively referred to as the Project. The electrical generation capacity of the solar (photovoltaic) Project 
would be up to 800 MWac and the BESS would have a net power capacity of up to 800 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 has at least two CPA application phases 
(see Table 1 below). Permitting phase 2 of the Project, and subject of this CPA, would be located on up to 
1,997 acres of land in unincorporated Maricopa County (County), approximately 30 miles west of the Town 
of Gila Bend. CPA permitting phase 2 of the Project is located adjacent to 3,619 acres (CPA permitting phase 
1 of the Project) that went through the CPA process in 2021 (CPA #2021011) (Figure 1). The entire area of 
5,616 acres is intended to be developed for solar power generation and become a unified development. 
The table below describes past and current land entitlement permitting for both phases of the Project.

The Project would include up to 1,200,000 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, and operation and maintenance (O&M) building that would include a connection to a new 
septic system. The Project would interconnect to one of the 500kV Hoodoo Wash – Hassayampa 
transmission lines owned by San Diego Gas & Electric (SDG&E) and controlled through the California 
Independent System Operator (CAISO), located 0.4 mile north of Hyder Road. The substation, BESS, and 
O&M building would be located on up to 45 acres within the area included in Phase 1, (see Figure 1). The 
Project transmission interconnect is anticipated to be less than 800 feet in length that would connect to a 
500-kilovolt (kV) transmission line on 135- to 155-foot structures above grade within an up to 200-foot 
right-of-way (ROW). The Project plans to apply for a variance to the 120-foot maximum height restriction 
during the zoning application process. The expected maximum net output, at the proposed point of 
interconnection from the combined solar modules and BESS is up to 800 MWac. The design life of the 
Project is anticipated to be 40 years.

1.1 
On-site and Regional Location 
The Developer’s site is situated northeast of the Agua Caliente Mountains and north of the Gila River (Figure 
1). Topographically, the site slopes slightly to the southeast toward the Gila River. Elevations within the 
Project site range between approximately 968 – 448 feet above mean sea level. The site is primarily open 
desert land and agricultural crop land and was historically native desert land. The regional ecological biome 
associated with the site can be characterized as dynamic, occurring south of rugged mountains and north 
of the Gila River. That being said, the local area has been heavily modified to support human habitation to 
include a transportation corridor, pipeline, county-maintained road network, telecommunications, above 
and below ground powerlines, and other planned or built solar farms in addition to the rural desert/ag 
lifestyle presents. The Developer would make all reasonable efforts to mitigate potential impacts to the 
natural and human environments; however, at this early stage the Project buildable area is still being defined 
during this planning phase of the Project. Final layout would be presented during the zoning phase.  
The Project is bounded by Butterfield Stage Road to the north, the Gila River to the east and south, and the 
Maricopa and Yuma County boundary to the west. Generally, the center of the Project is located at Hyder 
Road and Agua Caliente Road. The Project would interconnect to the 500kV Hoodoo Wash - Hassayampa 
line transmission line (Hoodoo 500kV), located 0.4 miles north of Hyder Road. This interconnect is not 
expected to exceed 800-feet from Project switchyard to Hoodoo 500kV The Developer’s site consists of 
multiple parcels of land within the following Township (T), Range (R) and Sections: 
• 
T4SN/10W: Sections 30, 31, and; 
• 
T5S/R10W: Sections 5, 6, 7, 10, 15, 16, 17, and 18. 
The Developer has secured site control options for all parcels included within the Phase 2 Project 
boundary (Figure 2). A list of all parcels within the Phase 2 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 2,010 acres from Rural 
Development Area to Utilities (Figure 3).  
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). Also included within Phase 
1 are three parcels and a portion of four others designated as approved for Special Use as a solar land use 
for the previously approved Verma Solar Hyder Parcels 1 and 2 (CPA2009023 and CPA2009024; 
approximately 182 acres). One parcel, Assessor Parcel Number (APN) 403-29-123C, in Phase 2 has two 
previously approved special use permits for use as an agricultural processing plant (Z91-30) and a cotton 
gin (Z77-26). An out of service Union Pacific Railroad (UP) right of way, the existing 500kV Hoodoo Wash - 
Hassayampa transmission line corridor, and a Kinder Morgan natural gas pipeline all bisect the site parallel 
to Hyder Road. Various above-ground electric lines occur in and around the site. Medium voltage electrical 
(i.e., 34.5kV) connectors would be required to be installed either over or under Hyder Road, the UP ROW 
and other utilities along this corridor. The Developer is pursuing encroachment permits from these entities.

1.3 
Roads/Transportation Systems Serving the Project 
The Project site is located approximately 12 miles north of Interstate 8, via Agua Caliente Road. The Project 
site is currently accessible along Hyder Road, bisecting the site southwest to northeast, as well as by Agua 
Caliente Road, bisecting north to south. The two CPA land areas (Phase 1 and Phase 2) would form a unified 
5,629-acre project and the Project would be accessed using the existing graded and asphalt-paved 
major/minor/local/farm roads within the Project site. There are two portions of the site that were included 
in the parcel acquisition for the Project, but the Developer does not intend to utilize for solar development 
(see Avoidance Areas in Figure 1). 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. Two CPAs were approved in 2011 (Verma Solar Hyder Parcels 1 and 2 
[CPA 2009023 and CPA 2009024]) under an older land use designation for solar Projects within Phase 1. 
Although these sites were never developed, the suitability of this Project with surrounding land uses is 
demonstrated by the County’s approval of these types of uses (i.e., solar farms); high voltage transmission 
lines occur near the site; and existing substation connecting to distribution level lines along Hyder Road. 
Further, the Bureau of Land Management (BLM) has established two Solar Energy Zones in the vicinity of 
the site, Agua Caliente (10 miles to the west) and Gillespie (25 miles to the east). These Solar Energy Zones 
have been identified by BLM as areas well suited for utility-scale production of solar energy, where the BLM 
will prioritize solar energy and associated transmission infrastructure development.  
The site is relatively flat, primarily native desert land and agricultural land and is surrounded by agricultural 
land and native desert land. Dust generation as a result of 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. The nearest residence is located approximately 0.2 miles west of the site, near the junction 
of Yuma County Road 14 and Palomas Road/Hyder Road, in Yuma County. One additional residence is 
located further south on the east side of Avenue 76E in Yuma County. On the south side of the Agua Caliente 
Mountains along Old Agua Caliente Road there is a residence approximately 0.6 miles southwest of the site. 
The Agua Caliente Mountains provide screening of the Project from this residence and other residences 
further west along Old Agua Caliente Road. The next closest residence is located approximately 0.3 miles 
west of the eastern portion of Phase 2. This residence is associated with Desert Springs Tilapia, operated by 
MainStream USA, LLC, a participating landowner.  
The Project is located below three Military Training Routes (MTRs): Visual Route 231, 243, and 245. On these 
routes, pilots are authorized to fly as low as 300 feet above ground level. Wood reached out to Luke Air 
Force Base (LAFB), who provided a letter dated September 15, 2022 stating that LAFB does not expect that 
the proposed CPA would affect LAFB flying operations; however, they request the right to comment further 
as construction plans are submitted to County Planning to determine if any structural impacts exist. 
Additionally, LAFB recommended that the Project go through the Department of Defense (DoD) Informal

Clearinghouse process. The Project initiated the Informal Review process on August 18, 2022, and was 
assigned Tracking Number 2022-08-S-DEV-16. The DoD responded on September 29, 2022, and has 
requested additional information regarding construction of the Project. The Project expects ongoing 
coordination with LAFB and DoD to occur during the zoning phase of the Project.

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 be built in up to five construction phases of up to 300 MWs each. The Project would 
benefit local, County, state, and regional economies by providing temporary employment opportunities for 
several hundred professionals during each phase of construction, which would occur over 18- to 24-month 
construction windows, beginning as early as 2024 and be completed by 2025/2027. The Project expects to 
require 20 daily workers at the start of each construction phase. As the construction and assembly ramps 
up for each construction phase, the Project could hire as many as 250-350 daily 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.

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 use within the site is open space (i.e., undeveloped native desert land). Other existing 
land uses within the site include utilities and commercial/industrial operations. These land uses would 
continue with the implementation of the Project.  
Some 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.  
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 Developer. 
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 shall 
be borne by the Developer. 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, shall be borne by the Developer. 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.  
During construction, traffic would increase in the area. However, this would be a temporary impact to the 
transportation network only during the construction phase. The Project would be built in up to five 
construction phases of up to 300 MWs each. 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 in an effort 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 lines, solar electrical generating 
facilities) as well as above-ground electrical distribution lines and transportation networks within the Project 
area and the region. The Developer understands that the County would require a site enclosure and

screening to provide screening where the Project is adjacent to existing residences. This screening 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. 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 
associated with the Zone Overlay process. 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 team has conducted initial surveys to describe the ecological conditions across the 
Project area several times in 2021 and 2022. In addition to a field site investigation, the US Fish and Wildlife 
Service Information for Planning and Consultation website and the AZGFD Online Environmental Review 
Tool have been queried for information on special status species, including federal threatened and 
endangered species, for the Project area. The Project site and surrounding area is predominately open 
desert lands, with limited agricultural development in the vicinity. The native vegetation present is 
dominated by widely spaced desert scrub vegetation including creosote, saltbush and Sonoran Desert scrub 
habitats. Desert washes are dominated by live and dead or dormant salt-cedar. There are no federally-listed 
plant or wildlife species that are likely to occur in the Project area, but Sonoran pronghorn is considered to 
have low likelihood to occur in the area. In addition, there are some species of concern, such as migratory 
birds and raptors, which have potential to occur in the area.  
The team has been coordinating with wildlife agencies, particularly the Arizona Game and Fish Department 
(Department) since October 2021, during the 2021 CPA (CPA2021011) application process, and began 
coordinating with AGFD for the CPA2022009 in July 2022 to develop protection measures and address 
concerns with these species. The Project is still in the early planning phases and discussions with wildlife 
agencies are still underway. Protection measures may include pre-construction surveys for some species as 
well as biological monitoring during construction.  
Native plants protected under Arizona Native Plant Law, administered by the Arizona Department of 
Agriculture, would be identified on the site prior to construction and relocated or salvaged as required. 
Native plant removal, relocation, or sale would be noticed as required by Arizona Administrative Code Title 
3, Chapter 3, Article II. The Project shall avoid the Gila River as well as identified Waters of the United States 
and wetlands. Appropriate best management practices (BMPs) and retention basins would be included in 
the Project design and construction to minimize impacts to surface water runoff.

Consultation with the Arizona State Historic Preservation Office (SHPO) has been initiated to identify 
significant cultural resources. A Class I and Class III Cultural Resources Inventory and Pedestrian survey were 
completed and the SHPO has concurred that no cultural resources identified are eligible for listing on the 
National Register and no further surveys are warranted. It should be noted, 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.  
Finally, 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. The Developer understands that the County may require 
an 80% opacity screen be constructed in areas adjacent to existing residences to minimize visual impact.

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. Solar and 
storage projects such as 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 such as Lake Mead cannot 
recharge at the rates that they are being depleted. The Project would be a low water use facility 
(construction = approximately 30,000 gallons per acre and O&M = approximately 200 gallons per acre 
per year), 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: 
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, with the exception of 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 1. 
The Developer believes the Project is well suited for the selected area, given the availability of a large 
amount of relatively flat land. Further, proximity to the 500kV Hoodoo Wash - Hassayampa transmission 
line corridor makes this location ideal in terms of minimizing the long electrical interconnects required for 
the transmission of electricity to the regional electrical grid. Moreover, the area surrounding the site is 
mostly undeveloped, although agricultural lands are located to the north and south of the site.  
It is recognized that several residences occur outside of but near the Project, to the west, southwest, and 
one residence north of the southeastern portion of the Project. U.S. Census tract data indicate approximately 
9 households are located within 2 miles of the Project. All landowners within 300 feet of the Project site 
have been sent notification letters soliciting comments, questions, and concerns regarding the proposed 
Project. Signs to notify the public have been posted along County-maintained roadways. The existing visual

setting has been previously impacted by electrical infrastructure including high voltage transmission lines, 
and electrical substations; transportation network (e.g., arterial roads and railway); and agricultural farms 
and their attendant infrastructure (e.g., water pumps, canals, farm roads, distribution lines, agricultural 
processing plant and cotton gin). Further, for residences south of the Project, the Agua Caliente Mountains 
provide screening of the Project from these residences. 
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 an area that already has a 
500kV transmission line present (i.e., the 500kV Hoodoo Wash – Hassayampa transmission line) and would 
be relatively short, anticipated to be less than 1,500 feet in length. 
Finally, the Developer 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 Developer 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. 
Table 1 includes a complete accounting of relevant comprehensive plan elements, their attendant policies, 
and the consistency of the Project with these policies.

resource to generate electricity for the southwest and 
western grid – a demonstration of efficient, orderly 
growth by the County. While this area is currently rural, 
it provides services and infrastructure that urban growth 
areas utilize and would provide a foundation for future 
urban growth patterns to consider.

Consistency with Comprehensive Plan 
Open Space Element 
Open Space 
Goal # 1 
Provide regional leadership to 
promote environmental quality, 
including the preservation of 
open, 
natural 
park 
and 
recreation lands. 
Consistent 
This Project would enable the County to site utility-scale 
solar generation near existing electrical infrastructure 
and agricultural use, in an area that development would 
result in limited impact to open space lands and would 
demonstrate efficient, orderly growth. In addition, the 
Project would generate renewable energy that would 
result in improved air quality through reduced 
emissions for electric generation, allowing Maricopa 
County to provide regional leadership in promoting 
environmental quality through improved air quality in 
the County.  
Open Space 
Policy #2  
Maricopa 
County 
supports 
dedication and improvement of 
trail right-of-way within new 
development, 
including 
the 
Maricopa Trail and Maricopa 
County Regional Trail System. 
Consistent 
While the Project may not include trail development, we 
support the development of recreational resources and 
connectivity for users, including trail right-of-way and 
the greater Maricopa County Regional Trail System.  
Water Resources Element 
Water Resources  
Goal #2 
Provide leadership to promote 
regional water quality and water 
use. 
Consistent 
The Project does not require water in the generation of 
electrical power and requires very little water for panel 
and equipment maintenance. By promoting solar 
electrical generation, the County provides leadership on 
responsible water use by enabling low-water use 
infrastructure to provide the southwest and western 
electrical grid with a renewable source of electricity.  
Water Resources  
Goal #3 
Increase renewable water use. 
Consistent 
Pursuant to the Vision 2030 Comprehensive Plan (p95), 
“Surface water is considered the State’s major 
renewable water source and comes from rivers, streams 
and lakes.” The Project would not increase water 
withdrawal from rivers, streams, and lakes. However, 
effluent is not planned as a source of water for the 
Project.

Water Resources  
Goal #4 
Increase water conservation. 
Consistent  
Electricity generation utilizing traditional fossil fuels is 
highly water intensive. In contrast, solar and storage 
Projects such as this Project require very little water 
(comparatively) 
for 
construction 
and 
operation. 
Meeting electric power demands with solar power & 
battery storage would further the goal of increased 
water conservation within Maricopa County. 
Water Resources  
Policy #2  
Maricopa County supports water 
conservation techniques in the 
planning and design of new 
development. 
Consistent 
The Project does not require water in the generation of 
electrical power and requires very little water for panel 
and equipment maintenance. Very little water would be 
required 
for 
construction 
activities. 
Water 
for 
construction and long term O&M would come from on-
site private ground water wells. The approximate water 
usage for construction is 30,000 gallons per acre and 
during O&M is 200 gallons per acre per annum. The 
Project would be designed to incorporate feasible water 
conservation techniques. 
Water Resources  
Policy #4  
Maricopa 
County 
supports 
compliance with its Drinking 
Water 
and 
Water 
and 
Wastewater 
Treatment 
Programs. 
Consistent 
The Project would be consistent with Maricopa County’s 
Drinking and Wastewater Treatment programs. 
Water Resources  
Policy #5  
Maricopa County supports low 
water 
use 
solar 
electric 
generating technologies. 
Consistent 
The Project does not require water in the generation of 
electrical power and requires very little water for panel 
and equipment maintenance. Panel washing may be 
required if bi-annual rains are not sufficient or if soiling 
of panels is excessive due to dust accumulation. 
Water Resources  
Policy #7  
Maricopa County supports low 
water use and drought-tolerant 
landscaping. 
Consistent 
Any required landscaping for the Project would use 
drought-tolerant low-water-use landscaping. The water 
to support any required Project landscaping would 
come from on-site private wells.

Energy Element 
Energy  
Goal #1 
Provide leadership to promote 
regional environmental quality. 
Consistent 
The electricity generated by the Project would be 
distributed to the regional electrical grid and wider 
west/southwest regions and would result in improved 
air quality through reduced emissions for electric 
generation, providing a benefit to air quality in 
Maricopa County. Appropriate protective measures for 
biological 
and 
cultural 
resources 
would 
be 
implemented to minimize or prevent impacts to these 
resources. The Project would require very little water for 
construction 
and 
operation. 
Amending 
the 
Comprehensive Plan to enable this Project would 
demonstrate 
responsible 
leadership 
to 
promote 
regional environmental quality. 
Energy  
Goal #2 
Make Maricopa County a leader 
in alternative energy research 
and development. 
Consistent 
The Project is a utility-scale solar and storage Project. 
While utility-scale solar is not a “new” technology, the 
battery energy storage system is a fairly new technology 
in utility-scale renewable energy generation. Solar 
industry trends are leaning towards battery storage 
systems in an effort to increase reliability and maximize 
the production of stored energy when the sun sets. 
Energy  
Policy #1 
Maricopa 
County 
supports 
energy efficient design and 
construction 
of 
new 
development. 
Consistent 
The Project would utilize current technologies and best 
practices in all components to support energy efficient 
design and construction. All Project components (e.g., 
panels, inverters, SCADA, batteries) would utilize 
leading edge technology to insure the most efficient 
solar generation and storage system is developed. 
Energy Policy #4  
To limit energy consumption, 
Maricopa 
County 
supports 
alternative 
transportation 
options in new development. 
Consistent 
During construction, employees would be encouraged 
to carpool to the site to reduce the number of personal 
vehicle trips and emissions. Once operational, the 
Project site would require minimal staff (2-3 personnel 
per 8-hour shift [24-hour round the clock staffing]), 
resulting in few vehicle trips to and from the site. 
Energy  
Policy #6  
Maricopa County supports being 
a 
responsible 
leader 
in 
alternative energy research and 
development. 
Consistent 
The Project is a utility-scale solar and battery storage 
Project and would facilitate Maricopa County’s 
continued 
leadership 
in 
alternative 
energy 
development.

Dear Ms. Sprague, 
This letter is a continuation of our discussion associated with our 12 August 2022 correspondence, and 
subsequent meetings we’ve had with the Department. This letter represents the ‘yellow items’ 
associated with your 15 July 2022 letter, and our thoughts related to these yellow items. 
We look forward to continuing to work with the Department and speaking again on 27 September, 
2022. 
Kind regards,

Highlighted Points from Department Letter 
 
[2] The mitigation strategy would not extend beyond project construction (i.e., bird mortality studies, 
bird and mammal migration patterns, post-construction long-term monitoring of presence or absence of 
wildlife, data collection, reporting, etc.) 
[3] Based on our 14 September discussion, we understand that cumulative impacts associated with 
other solar projects in the ‘region’ (i.e., vicinity) is outside of the scope of our responsibility to conduct. 
[6] Previously discussed. 
[8] We intend to include kit fox presence or absence surveys during pre-construction surveys for other 
species (i.e. burrowing owls, MBTA, etc.) 
[11, 12] Would development of a WEAP suffice in training construction workers in the relocation of non-
threatening reptiles, excluding the desert tortoise? 
[19] WestLand conducted a data search of eagle nests in the vicinity of the Project, and determined no 
active eagle nests are present within 10 miles of the Project site. Therefore, there is no need to contact 
USFWS for this species. 
[21] Pursuant to Department’s 2010 Solar Guidelines, and previous discussions with the Department, it 
has been determined the Project site occurs in Resource Category IV that does not retain a no net loss 
requirement. We have identified two areas of the Project site in the southwest and the southeast 
quadrants that we feel would like to set aside for wildlife habit. A map of these areas will be provided. 
[23] Based on our 14 September discussion, the Project site will have numerous naturally occurring 
open corridors along public roadways, transmission lines, utility lines, etc, and also as a result of phase 
construction. 
[24] A preliminary drainage plan has not been developed. We are looking at alternatives to comply with 
county water retention and offsite flow requirements. 
[27] A fencing plan and an advanced site layout have not been developed and will be included in the 
plan of development that accompanies in the zoning application.

 RE: 
 Hyder  Solar  and  Storage  Project  Major  Comprehensive  Plan  Amendment 
 (CPA2022009) 
 Dear Mr. Cannon: 
 The  Arizona  Game  and  Fish  Department  (Department)  appreciates  the  opportunity  to  review  the 
 Hyder  Solar  and  Storage  Project  Major  Comprehensive  Plan  Amendment  (CPA2022009).  The 
 Department  understands  that  Ellwood  Land  Holdings,  LLC  (Ellwood),  is  proposing  construction 
 of  a  500  MW  solar  photovoltaic  (PV)  facility  with  battery  storage  on  2,015  acres  of  land  in 
 unincorporated  Maricopa  County  (County)  approximately  30  miles  west  of  the  Town  of  Gila 
 Bend.  Most  of  the  project  area  occurs  in  desert  scrub  habitat  with  some  portions  in  riparian 
 habitat  and  agricultural  lands  north  and  east  of  the  Agua  Caliente  Mountains,  with  the  southern 
 portion  extending  into  the  mountains.  The  project  is  adjacent  to  3,619  acres  of  a  similar  solar 
 project  that  was  approved  through  the  MCPA  process  in  2021  (CPA2021011).  The  Department 
 understands these two projects would be considered a unified development on 5,634 acres. 
 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  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  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  Ellwood  and  the  County  during  the  planning  and  development  of  this 
 economically-important  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  mitigate  potential  impacts  to  wildlife  and  recreational 
 access  during  development  and  operation  of  the  facilities.  For  your  consideration,  the

 Department  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  solar 
 energy  generation  projects,  including  several  in  the  vicinity  of  the  proposed  Hyder  Solar  facility. 
 Although  each  individual  project  may  have  a  minimal  impact  on  the  broader  landscape,  these 
 projects  cumulatively  could  result  in  substantial  loss  of  habitat,  impact  wildlife  movements,  and 
 affect  wildlife  related  recreation.  It  is  important  for  this  project  to  be  evaluated  in  association 
 with  other  similar  projects  in  the  region.  Long-term  effects  to  wildlife  can  extend  several 
 kilometers  beyond  the  footprint  of  a  project  area  ( Sawyer  et  al.  2022  ),  and  the  Department 
1
 recommends  that  the  County  and  Ellwood  consider  these  effects  in  its  evaluation  of  this 
 application.  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. 
 During  the  planning  process,  the  Department  recommends  surveys  and  monitoring  be  conducted 
 to  determine  species  presence  and  potential  conflicts.  As  referenced  in  Guidelines  for  Solar 
 Development  in  Arizona  ,  these  surveys  should  be  of  sufficient  duration  and  intensity  to 
2
 adequately  assess  all  habitat  types  and  potential  species  occurrence  in  and  adjacent  to  the  project 
 area.  If  this  project  is  approved,  Department  staff  are  available  to  assist  Ellwood  in  determining 
 appropriate  design  features  and  best  management  practices  that  can  help  minimize  potential 
 impacts.  The  Department  offers  the  following  recommendations  to  reduce  impacts  to  wildlife 
 and habitat: 
 ●
 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  the  County  and  Ellwood  to
 minimize  any  potential  impacts  to  this  species  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  US  Fish  and  Wildlife  Service  (USFWS)  Arizona  Ecological  Services  Office  (AESO)
 and  the  Department’s  Sonoran  Pronghorn  Program  Lead  ( jbright@azgfd.gov )  as  soon  as
 possible.
 ●
 Kit  fox  are  likely  to  occur  within  the  project  area  and  could  be  influenced  by  loss  of
 habitat  and  connectivity.  Surveys  for  this  species  are  recommended  to  determine  potential
 impacts  and  to  inform  pre-construction  activities.  Department  staff  are  available  to  assist
 in identifying suitable conservation measures if foxes or their burrows are detected.
 ●
 The  Sonoran  desert  tortoise,  which  is  covered  under  a  Candidate  Conservation
 Agreement  (CCA),  could  occur  in  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
3
 tortoises  are  identified,  please  refer  to  and  implement  the  Recommended  Standard

 ●
 A  number  of  other  reptile  and  amphibian  species  have  potential  to  occur  in  the  project
 vicinity,  including  Gila  monster  and  lowland  leopard  frog,  which  are  Arizona  Species  of
 Greatest  Conservation  Need  (SGCN).  To  the  extent  feasible,  the  Department  recommends
 avoiding  areas  where  these  species  occur.  If  any  are  observed  during  construction
 activities,  the  Department  recommends  moving  them  no  more  than  0.25  mile  outside  the
 project  boundary.  To  aid  with  possible  relocations,  the  Department  recommends  that  all
 personnel  take  venomous  reptile  safety  training  from  a  reputable  source  so  any  Gila
 monsters  or  rattlesnakes  that  may  enter  the  site  can  be  safely  relocated  out  of  harm’s  way
 without injury or mortality to the animal.
 ●
 Large-scale  solar  PV  facilities  can  result  in  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  a  qualified  biologist  survey  for  bird  species
6
 within  the  project  area  to  better  understand  potential  impacts  from  these  projects.
 Adjustments  to  panel  spacing  could  help  break  up  the  illusion  of  water  and  reduce  bird
 mortality;  research  is  currently  being  conducted  to  assess  this  mitigation  option
 (Wilkening  and  Rautenstrauch  2019  ).  Additionally,  the  Department  recommends  surveys
7
 for  nesting  birds  be  conducted  prior  to  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)  and  protected  under  state  law.  Breeding  season  for  birds  in  this  area  is  generally
 mid-January  through  late  June.  If  it  is  anticipated  the  project  will  not  be  in  compliance
 with  MBTA,  the  Department  recommends  contacting  the  U.S.  Fish  and  Wildlife  Service
 (USFWS)  for  their  technical  assistance.  The  USFWS  will  provide  options  to  comply  with
 the MBTA.
 ●
 The  western  burrowing  owl,  a  special  status  species  that  is  regulated  under  the  MBTA,
 could  occur  within  the  project  area.  The  Department  recommends  conducting  occupancy
 surveys  for  western  burrowing  owls  throughout  the  project  area  to  determine  if  this
 species  occurs  within  the  project  footprints.  Guidelines  for  conducting  this  survey  are
 found  in  Burrowing  Owl  Project  Clearance  Guidance  for  Landowners  .  Please  note  that
8
 the  surveys  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  USFWS
 for direction, in accordance with the guidelines.
 ●
 Bald  eagles,  which  are  regulated  under  the  Bald  and  Golden  Eagle  Protection  Act
 (BGEPA),  could  occur  within  the  project  area.  If  uncertain  about  the  effects  of  the  project
 to  eagles,  or  if  it  is  anticipated  the  project  will  not  be  in  compliance  with  the  BGEPA,  the
 Department  recommends  contacting  the  USFWS  for  their  Technical  Assistance,  as  well
 as  Tuk  Jacobson,  the  Department’s  raptor  expert,  at  raptors@azgfd.gov  or  623-236-7575.

 The  USFWS  and  the  Department  will  provide  options  to  comply  with  the  BGEPA,  such 
 as conservation measures to avoid or minimize adverse effects to the eagles. 
 ●
 Protected  plant  species,  such  as  the  golden  cholla,  have  potential  to  occur  within  the
 project  area.  The  Department  recommends  conducting  native  plant  surveys  to  identify
 species  protected  under  Arizona’s  Native  Plant  Law.  Please  refer  to  Arizona's  Native
 Plant  Law  for  regulations,  a  list  of  native  plants  that  are  protected,  and  information  about
9
 conducting a Native Plant Inventory.
 ●
 The  southeastern  portion  of  the  project  area  contains  several  areas  of  riparian  habitat.  The
 Arizona  Game  and  Fish  Commission  and  the  Department  recognize  riparian  habitats  as
 areas  of  environmental  importance  to  wildlife.  The  Department  encourages  management
 practices  that  will  maintain  current  riparian  areas  so  that  there  is  no  net  loss  of  habitat,
 including  maintaining  a  150-foot  buffer  around  these  areas  and  appropriate  connections
 for  wildlife  movement.  Additional  recommendations  to  maintain  the  integrity  of  riparian
 areas can be found in these  Riparian Area Guidelines  .
10
 Maintaining  habitat  connectivity  is  a  high  priority  for  the  Department,  and  wildlife  movement 
 corridors  are  important  for  wildlife  to  respond  to  changing  environmental  conditions.  Attached 
 for  your  review  and  reference  is  the  Heritage  Data  Management  System  (HDMS)  Online 
 Environmental  Review  Tool  (ERT)  report  (HGIS-16731).  As  identified  in  the  report,  this  project 
 falls  within  two  identified  wildlife  movement  areas.  If  this  project  is  approved,  the  Department  is 
 available  to  share  its  expertise  on  measures  to  reduce  impacts  to  connectivity,  including  the 
 following: 
 ●
 The  Department  recommends  conducting  wildlife  movement  studies  in  the  project  area
 and  surrounding  landscape  to  inform  project  design.  Continued  movement  studies  during
 construction  and  post-construction  can  help  assess  the  broader  footprint  of  this  project
 and  inform  future  conservation  measures.  Department  staff  are  available  to  assist
 Ellwood in determining the scope and timeline of these studies.
 ●
 The  Department  recommends  maintaining  open  corridors  across  the  project  area  to
 facilitate  wildlife  movement.  The  Department  is  available  to  assist  in  development  of  the
 site  design  to  provide  input  on  possible  corridors  and  to  discuss  ways  to  maintain  the
 ephemeral  washes  that  occur  in  the  project  area  in  their  natural  state.  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  contain  crucial  riparian  habitat  and  serve  as  important
 landscape-level conveyance corridors for wildlife movement.
 ●
 To  the  extent  possible,  the  Department  recommends  retaining  habitat  features  underneath
 the  panels,  including  vegetation  and  soils,  instead  of  grading  the  entire  site.  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  ).

 The  Department’s  Wildlife  Compatible  Fencing  Guidelines  provide  information  on  how
12
 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  to  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  recommends  that  potential  impacts  to  recreation  and  Department  access 
 for  wildlife  management  activities  be  evaluated  during  the  planning  phase.  The  Department 
 prioritizes  conserving  existing  access  and  modes  of  access  for  hunting,  trapping,  shooting, 
 wildlife  watching,  off-highway  vehicle  use,  dispersed  camping,  and  other  responsible  forms  of 
 outdoor  recreational  use  on  public  lands  and  remains  available  to  assist  with  opportunities  to 
 maintain access within the project footprint.  .

VIA EMAIL: tsprague@azgfd.gov  
 
Dear Ms. Sprague, 
Thank you for your engagement on the proposed Hyder Solar and Storage Project (‘Project’) Ellwood is 
developing in Maricopa County. We appreciate the opportunity to discuss the purpose and need of the 
project with the Department and the insights of the Department in minimizing impacts to wildlife. 
This is in response to the Department letter of July 15th, 2022 to Adam Cannon, associated with the 
Major Comprehensive Plan Amendment (CPA 2022009). It should be understood the Department was 
asked by the County to comment on the project during the MCPA phase, or planning phase, and that 
specifically, we seek a letter from the Department supporting the MCPA while concurrently continuing 
consultation with the Department leading up to the zoning phase. 
In reviewing the recommendations, many items we are in general agreement as appropriate 
management practices to limit impacts to wildlife. However, others appear to be incompatible with 
utility scale solar projects. 
Since our July 21st meeting, we have characterized your recommendations in orange, yellow, and blue. 
• 
Orange – your recommendation is out of scope with typical permitting processes of this type, or 
incompatible with utility scale solar projects. Elaboration below. 
• 
Yellow – more discussion required for your recommendation. 
• 
Blue – Ellwood is in general agreement with your recommendation. 
Your July 15th letter links to the Arizona Game and Fish Department Guidelines for Solar Development in 
Arizona. In this guidance, wildlife habitat within Arizona is defined as either Resource Category I, II, III, or 
IV. Based on definitions of categories in this guidance and the biological studies taken place to date, we 
feel the project occurs in Resource Category IV. We feel it is important to be in agreement with the 
Department related to what Resource Category the project is defined. 
We look forward to continuing to work with the Department and speaking again on August 25th, 2022. 
Kind regards, 
Marcus

Highlighted Points from Department Letter 
 
[6] We feel it is important to be in agreement with the Department related to what Resource Category 
the project is defined. 
[4] [5] The impetus for Department consultation is the MCPA, a mere change of land use, which itself is 
focused solely on the compatibility of project and immediate vicinity with county comprehensive plan. 
And ‘similar’ and ‘region’ are subjective, and potentially leading to tying together the fate of many 
projects. The Project cannot proceed with this recommendation. 
[14] This is incompatible with utility-scale solar. There is no spacing that would break up this purported 
illusion, and yet maintain technical, economical and land acquisition requirements. The Project cannot 
proceed with this recommendation. 
[22] The impetus for Department consultation is the MCPA, a mere change of land use, which itself is 
focused solely on the compatibility of project and immediate vicinity with county comprehensive plan. It 
is not the Project’s mandate to conduct regional programmatic wildlife studies nor is it feasible given 
access constraints. Therefore, the Project cannot proceed with this recommendation. 
[25] This is incompatible with utility-scale solar. Vegetation under panels would interfere with the 
mechanicals of the trackers and present a fire fuel-loading hazard that would be a large risk to humans 
and wildlife and wildlife habitat in the area. The Project cannot proceed with this recommendation.

[28] This is incompatible with utility-scale solar. While ordinarily low risk, the project would carry 
voltage and heat that could harm untrained persons. And this project would be classified as part of the 
national security infrastructure. And personnel safety is of great concern to Ellwood. The Project cannot 
proceed with this recommendation.

 RE: 
 Hyder  Solar  and  Storage  Project  Major  Comprehensive  Plan  Amendment 
 (CPA2022009) 
 Dear Mr. Cannon: 
 The  Arizona  Game  and  Fish  Department  (Department)  appreciates  the  opportunity  to  review  the 
 Hyder  Solar  and  Storage  Project  Major  Comprehensive  Plan  Amendment  (CPA2022009).  The 
 Department  understands  that  Ellwood  Land  Holdings,  LLC  (Ellwood),  is  proposing  construction 
 of  a  500  MW  solar  photovoltaic  (PV)  facility  with  battery  storage  on  2,015  acres  of  land  in 
 unincorporated  Maricopa  County  (County)  approximately  30  miles  west  of  the  Town  of  Gila 
 Bend.  Most  of  the  project  area  occurs  in  desert  scrub  habitat  with  some  portions  in  riparian 
 habitat  and  agricultural  lands  north  and  east  of  the  Agua  Caliente  Mountains,  with  the  southern 
 portion  extending  into  the  mountains.  The  project  is  adjacent  to  3,619  acres  of  a  similar  solar 
 project  that  was  approved  through  the  MCPA  process  in  2021  (CPA2021011).  The  Department 
 understands these two projects would be considered a unified development on 5,634 acres. 
 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  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  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  Ellwood  and  the  County  during  the  planning  and  development  of  this 
 economically-important  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  mitigate  potential  impacts  to  wildlife  and  recreational 
 access  during  development  and  operation  of  the  facilities.  For  your  consideration,  the

 Department  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  solar 
 energy  generation  projects,  including  several  in  the  vicinity  of  the  proposed  Hyder  Solar  facility. 
 Although  each  individual  project  may  have  a  minimal  impact  on  the  broader  landscape,  these 
 projects  cumulatively  could  result  in  substantial  loss  of  habitat,  impact  wildlife  movements,  and 
 affect  wildlife  related  recreation.  It  is  important  for  this  project  to  be  evaluated  in  association 
 with  other  similar  projects  in  the  region.  Long-term  effects  to  wildlife  can  extend  several 
 kilometers  beyond  the  footprint  of  a  project  area  ( Sawyer  et  al.  2022  ),  and  the  Department 
1
 recommends  that  the  County  and  Ellwood  consider  these  effects  in  its  evaluation  of  this 
 application.  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. 
 During  the  planning  process,  the  Department  recommends  surveys  and  monitoring  be  conducted 
 to  determine  species  presence  and  potential  conflicts.  As  referenced  in  Guidelines  for  Solar 
 Development  in  Arizona  ,  these  surveys  should  be  of  sufficient  duration  and  intensity  to 
2
 adequately  assess  all  habitat  types  and  potential  species  occurrence  in  and  adjacent  to  the  project 
 area.  If  this  project  is  approved,  Department  staff  are  available  to  assist  Ellwood  in  determining 
 appropriate  design  features  and  best  management  practices  that  can  help  minimize  potential 
 impacts.  The  Department  offers  the  following  recommendations  to  reduce  impacts  to  wildlife 
 and habitat: 
 ●
 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  the  County  and  Ellwood  to
 minimize  any  potential  impacts  to  this  species  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  US  Fish  and  Wildlife  Service  (USFWS)  Arizona  Ecological  Services  Office  (AESO)
 and  the  Department’s  Sonoran  Pronghorn  Program  Lead  ( jbright@azgfd.gov )  as  soon  as
 possible.
 ●
 Kit  fox  are  likely  to  occur  within  the  project  area  and  could  be  influenced  by  loss  of
 habitat  and  connectivity.  Surveys  for  this  species  are  recommended  to  determine  potential
 impacts  and  to  inform  pre-construction  activities.  Department  staff  are  available  to  assist
 in identifying suitable conservation measures if foxes or their burrows are detected.
 ●
 The  Sonoran  desert  tortoise,  which  is  covered  under  a  Candidate  Conservation
 Agreement  (CCA),  could  occur  in  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
3
 tortoises  are  identified,  please  refer  to  and  implement  the  Recommended  Standard

 ●
 A  number  of  other  reptile  and  amphibian  species  have  potential  to  occur  in  the  project
 vicinity,  including  Gila  monster  and  lowland  leopard  frog,  which  are  Arizona  Species  of
 Greatest  Conservation  Need  (SGCN).  To  the  extent  feasible,  the  Department  recommends
 avoiding  areas  where  these  species  occur.  If  any  are  observed  during  construction
 activities,  the  Department  recommends  moving  them  no  more  than  0.25  mile  outside  the
 project  boundary.  To  aid  with  possible  relocations,  the  Department  recommends  that  all
 personnel  take  venomous  reptile  safety  training  from  a  reputable  source  so  any  Gila
 monsters  or  rattlesnakes  that  may  enter  the  site  can  be  safely  relocated  out  of  harm’s  way
 without injury or mortality to the animal.
 ●
 Large-scale  solar  PV  facilities  can  result  in  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  a  qualified  biologist  survey  for  bird  species
6
 within  the  project  area  to  better  understand  potential  impacts  from  these  projects.
 Adjustments  to  panel  spacing  could  help  break  up  the  illusion  of  water  and  reduce  bird
 mortality;  research  is  currently  being  conducted  to  assess  this  mitigation  option
 (Wilkening  and  Rautenstrauch  2019  ).  Additionally,  the  Department  recommends  surveys
7
 for  nesting  birds  be  conducted  prior  to  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)  and  protected  under  state  law.  Breeding  season  for  birds  in  this  area  is  generally
 mid-January  through  late  June.  If  it  is  anticipated  the  project  will  not  be  in  compliance
 with  MBTA,  the  Department  recommends  contacting  the  U.S.  Fish  and  Wildlife  Service
 (USFWS)  for  their  technical  assistance.  The  USFWS  will  provide  options  to  comply  with
 the MBTA.
 ●
 The  western  burrowing  owl,  a  special  status  species  that  is  regulated  under  the  MBTA,
 could  occur  within  the  project  area.  The  Department  recommends  conducting  occupancy
 surveys  for  western  burrowing  owls  throughout  the  project  area  to  determine  if  this
 species  occurs  within  the  project  footprints.  Guidelines  for  conducting  this  survey  are
 found  in  Burrowing  Owl  Project  Clearance  Guidance  for  Landowners  .  Please  note  that
8
 the  surveys  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  USFWS
 for direction, in accordance with the guidelines.
 ●
 Bald  eagles,  which  are  regulated  under  the  Bald  and  Golden  Eagle  Protection  Act
 (BGEPA),  could  occur  within  the  project  area.  If  uncertain  about  the  effects  of  the  project
 to  eagles,  or  if  it  is  anticipated  the  project  will  not  be  in  compliance  with  the  BGEPA,  the
 Department  recommends  contacting  the  USFWS  for  their  Technical  Assistance,  as  well
 as  Tuk  Jacobson,  the  Department’s  raptor  expert,  at  raptors@azgfd.gov  or  623-236-7575.

 The  USFWS  and  the  Department  will  provide  options  to  comply  with  the  BGEPA,  such 
 as conservation measures to avoid or minimize adverse effects to the eagles. 
 ●
 Protected  plant  species,  such  as  the  golden  cholla,  have  potential  to  occur  within  the
 project  area.  The  Department  recommends  conducting  native  plant  surveys  to  identify
 species  protected  under  Arizona’s  Native  Plant  Law.  Please  refer  to  Arizona's  Native
 Plant  Law  for  regulations,  a  list  of  native  plants  that  are  protected,  and  information  about
9
 conducting a Native Plant Inventory.
 ●
 The  southeastern  portion  of  the  project  area  contains  several  areas  of  riparian  habitat.  The
 Arizona  Game  and  Fish  Commission  and  the  Department  recognize  riparian  habitats  as
 areas  of  environmental  importance  to  wildlife.  The  Department  encourages  management
 practices  that  will  maintain  current  riparian  areas  so  that  there  is  no  net  loss  of  habitat,
 including  maintaining  a  150-foot  buffer  around  these  areas  and  appropriate  connections
 for  wildlife  movement.  Additional  recommendations  to  maintain  the  integrity  of  riparian
 areas can be found in these  Riparian Area Guidelines  .
10
 Maintaining  habitat  connectivity  is  a  high  priority  for  the  Department,  and  wildlife  movement 
 corridors  are  important  for  wildlife  to  respond  to  changing  environmental  conditions.  Attached 
 for  your  review  and  reference  is  the  Heritage  Data  Management  System  (HDMS)  Online 
 Environmental  Review  Tool  (ERT)  report  (HGIS-16731).  As  identified  in  the  report,  this  project 
 falls  within  two  identified  wildlife  movement  areas.  If  this  project  is  approved,  the  Department  is 
 available  to  share  its  expertise  on  measures  to  reduce  impacts  to  connectivity,  including  the 
 following: 
 ●
 The  Department  recommends  conducting  wildlife  movement  studies  in  the  project  area
 and  surrounding  landscape  to  inform  project  design.  Continued  movement  studies  during
 construction  and  post-construction  can  help  assess  the  broader  footprint  of  this  project
 and  inform  future  conservation  measures.  Department  staff  are  available  to  assist
 Ellwood in determining the scope and timeline of these studies.
 ●
 The  Department  recommends  maintaining  open  corridors  across  the  project  area  to
 facilitate  wildlife  movement.  The  Department  is  available  to  assist  in  development  of  the
 site  design  to  provide  input  on  possible  corridors  and  to  discuss  ways  to  maintain  the
 ephemeral  washes  that  occur  in  the  project  area  in  their  natural  state.  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  contain  crucial  riparian  habitat  and  serve  as  important
 landscape-level conveyance corridors for wildlife movement.
 ●
 To  the  extent  possible,  the  Department  recommends  retaining  habitat  features  underneath
 the  panels,  including  vegetation  and  soils,  instead  of  grading  the  entire  site.  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  ).

 The  Department’s  Wildlife  Compatible  Fencing  Guidelines  provide  information  on  how
12
 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  to  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  recommends  that  potential  impacts  to  recreation  and  Department  access 
 for  wildlife  management  activities  be  evaluated  during  the  planning  phase.  The  Department 
 prioritizes  conserving  existing  access  and  modes  of  access  for  hunting,  trapping,  shooting, 
 wildlife  watching,  off-highway  vehicle  use,  dispersed  camping,  and  other  responsible  forms  of 
 outdoor  recreational  use  on  public  lands  and  remains  available  to  assist  with  opportunities  to 
 maintain access within the project footprint.  .

 Dear Mr. Cannon: 
 The  Arizona  Game  and  Fish  Department  (Department)  appreciates  the  opportunity  to  review  the 
 Hyder  Solar  and  Storage  Project  Major  Comprehensive  Plan  Amendment  (CPA2022009).  The

 activities,  the  Department  recommends  moving  them  no  more  than  0.25  mile  outside  the 
 project  boundary.  To  aid  with  possible  relocations,  the  Department  recommends  that  all 
 personnel  take  venomous  reptile  safety  training  from  a  reputable  source  so  any  Gila 
 monsters  or  rattlesnakes  that  may  enter  the  site  can  be  safely  relocated  out  of  harm’s  way 
 without injury or mortality to the animal. 
 ●  Large-scale  solar  PV  facilities  can  result  in  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  a  qualified  biologist  survey  for  bird  species 
6
 within  the  project  area  to  better  understand  potential  impacts  from  these  projects. 
 Adjustments  to  panel  spacing  could  help  break  up  the  illusion  of  water  and  reduce  bird 
 mortality;  research  is  currently  being  conducted  to  assess  this  mitigation  option 
 (Wilkening  and  Rautenstrauch  2019  ).  Additionally,  the  Department  recommends  surveys 
7
 for  nesting  birds  be  conducted  prior  to  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)  and  protected  under  state  law.  Breeding  season  for  birds  in  this  area  is  generally 
 mid-January  through  late  June.  If  it  is  anticipated  the  project  will  not  be  in  compliance 
 with  MBTA,  the  Department  recommends  contacting  the  U.S.  Fish  and  Wildlife  Service 
 (USFWS)  for  their  technical  assistance.  The  USFWS  will  provide  options  to  comply  with 
 the MBTA. 
 ●  The  western  burrowing  owl,  a  special  status  species  that  is  regulated  under  the  MBTA, 
 could  occur  within  the  project  area.  The  Department  recommends  conducting  occupancy 
 surveys  for  western  burrowing  owls  throughout  the  project  area  to  determine  if  this 
 species  occurs  within  the  project  footprints.  Guidelines  for  conducting  this  survey  are 
 found  in  Burrowing  Owl  Project  Clearance  Guidance  for  Landowners  .  Please  note  that 
8
 the  surveys  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  USFWS 
 for direction, in accordance with the guidelines. 
 ●  Bald  eagles,  which  are  regulated  under  the  Bald  and  Golden  Eagle  Protection  Act 
 (BGEPA),  could  occur  within  the  project  area.  If  uncertain  about  the  effects  of  the  project 
 to  eagles,  or  if  it  is  anticipated  the  project  will  not  be  in  compliance  with  the  BGEPA,  the 
 Department  recommends  contacting  the  USFWS  for  their  Technical  Assistance,  as  well 
 as  Tuk  Jacobson,  the  Department’s  raptor  expert,  at  raptors@azgfd.gov  or  623-236-7575.

 The  USFWS  and  the  Department  will  provide  options  to  comply  with  the  BGEPA,  such 
 as conservation measures to avoid or minimize adverse effects to the eagles. 
 ●  Protected  plant  species,  such  as  the  golden  cholla,  have  potential  to  occur  within  the 
 project  area.  The  Department  recommends  conducting  native  plant  surveys  to  identify 
 species  protected  under  Arizona’s  Native  Plant  Law.  Please  refer  to  Arizona's  Native 
 Plant  Law  for  regulations,  a  list  of  native  plants  that  are  protected,  and  information  about 
9
 conducting a Native Plant Inventory. 
 ●  The  southeastern  portion  of  the  project  area  contains  several  areas  of  riparian  habitat.  The 
 Arizona  Game  and  Fish  Commission  and  the  Department  recognize  riparian  habitats  as 
 areas  of  environmental  importance  to  wildlife.  The  Department  encourages  management 
 practices  that  will  maintain  current  riparian  areas  so  that  there  is  no  net  loss  of  habitat, 
 including  maintaining  a  150-foot  buffer  around  these  areas  and  appropriate  connections 
 for  wildlife  movement.  Additional  recommendations  to  maintain  the  integrity  of  riparian 
 areas can be found in these  Riparian Area Guidelines  . 
10
 Maintaining  habitat  connectivity  is  a  high  priority  for  the  Department,  and  wildlife  movement 
 corridors  are  important  for  wildlife  to  respond  to  changing  environmental  conditions.  Attached 
 for  your  review  and  reference  is  the  Heritage  Data  Management  System  (HDMS)  Online 
 Environmental  Review  Tool  (ERT)  report  (HGIS-16731).  As  identified  in  the  report,  this  project 
 falls  within  two  identified  wildlife  movement  areas.  If  this  project  is  approved,  the  Department  is 
 available  to  share  its  expertise  on  measures  to  reduce  impacts  to  connectivity,  including  the 
 following: 
 ●  The  Department  recommends  conducting  wildlife  movement  studies  in  the  project  area 
 and  surrounding  landscape  to  inform  project  design.  Continued  movement  studies  during 
 construction  and  post-construction  can  help  assess  the  broader  footprint  of  this  project 
 and  inform  future  conservation  measures.  Department  staff  are  available  to  assist 
 Ellwood in determining the scope and timeline of these studies. 
 ●  The  Department  recommends  maintaining  open  corridors  across  the  project  area  to 
 facilitate  wildlife  movement.  The  Department  is  available  to  assist  in  development  of  the 
 site  design  to  provide  input  on  possible  corridors  and  to  discuss  ways  to  maintain  the 
 ephemeral  washes  that  occur  in  the  project  area  in  their  natural  state.  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  contain  crucial  riparian  habitat  and  serve  as  important 
 landscape-level conveyance corridors for wildlife movement. 
 ●  To  the  extent  possible,  the  Department  recommends  retaining  habitat  features  underneath 
 the  panels,  including  vegetation  and  soils,  instead  of  grading  the  entire  site.  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  ).

 ●  The  Department’s  Wildlife  Compatible  Fencing  Guidelines  provide  information  on  how 
12
 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  to  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  recommends  that  potential  impacts  to  recreation  and  Department  access 
 for  wildlife  management  activities  be  evaluated  during  the  planning  phase.  The  Department 
 prioritizes  conserving  existing  access  and  modes  of  access  for  hunting,  trapping,  shooting, 
 wildlife  watching,  off-highway  vehicle  use,  dispersed  camping,  and  other  responsible  forms  of 
 outdoor  recreational  use  on  public  lands  and  remains  available  to  assist  with  opportunities  to 
 maintain access within the project footprint.  .

To conserve Arizona's diverse wildlife resources and manage for safe, compatible outdoor recreation
opportunities for current and future generations.
Project Name:
Hyder Solar and Storage Project - MCPA No. CPA2022009
User Project Number:
CPA2022009
Project Description:
request for a Major Comprehensive Plan Amendment (CPA) to change the future land use designation
from Rural (0 - 1 d.u./ac.) to Utilities for the Hyder Solar and Storage Project (the project). Ellwood Land
Holdings, LLC (Ellwood), as the Applicant, is proposing the construction and operation of an up to 500 megawatt
alternating current (MWac) electrical generation facility consisting of solar modules and a battery energy storage
system (BESS), collectively referred to as the project. The electrical generation capacity of the solar
(photovoltaic) project will be up to 500 MWac and the BESS would have a net power capacity of up to 500
MWac. The BESS will likely be designed to go through a single charge/discharge cycle on a 24-hour basis,
storing/discharging up to 2 gigawatt hours (GWh). The project may be developed in at least two phases. The
project would be located on up to 2,015 acres of land in unincorporated Maricopa County (County),
approximately 30 miles west of the Town of Gila Bend. The project is located adjacent to 3,619 acres that went
through the Major Comprehensive Plan Amendment process in 2021 (CPA #2021011). The entire area of 5,634
acres is intended to be developed for solar power generation and become a unified development.

Review Date: 7/5/2022 12:58:33 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. HabiMap Arizona data, specifically Species of Greatest Conservation Need (SGCN) under our State Wildlife
Action Plan (SWAP) and Species of Economic and Recreational Importance (SERI), 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.

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 site map).

Project Type: Energy Storage/Production/Transfer, Energy Production (generation), photovoltaic solar facility
(new)
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.

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 herptefauna (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
(http://azstateparks.com/SHPO/index.html).
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.

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

Re:  Hyder Solar and Storage 2nd Letter (APNs:  401-85-044 thru 403-29-123C) 
 
Dear Mr. Cannon 
 
At the request of the Hyder Solar and Storage Development Team, Luke AFB would like to offer 
the following comments regarding the Comprehensive Plan Amendment Application which proposes a 
land use designation change from Rural Residential to Utilities.  The site sits on approximately 2,015 
acres and is located 30 miles west of the city of Gila Bend, bounded by Hyder Rd and Agua Caliente Rd 
in unincorporated Maricopa County, AZ.  The applicant is proposing the future construction and 
operation of a 500-megawatt electrical generation facility consisting of solar modules and a battery 
energy storage system (BESS).   
 
 
The land designation change from Rural Residential to Utilities will not affect Luke AFB flying 
operations; however, we request the right to comment further as construction plans are submitted to 
County Planning to determine if any structural impacts exist.  The site is located under several Military 
Training Routes (MTR) and therefore we requested the applicant submit for an informal review through 
the DoD Siting Clearinghouse for Energy, Installations, and Environment.  Luke AFB is aware this 
submission was done by the applicant on 18 Aug 2022.     
 
 
If you have any questions, please contact my Community Planner, Mr. Mark James at             
(623) 856-9981. 
 
             Sincerely

PROJECT DESCRIPTION 
This narrative report addresses the required information to support the request for an informal review by 
the Military Aviation and Installation Assurance Siting Clearinghouse to evaluate mission compatibility of 
the Hyder Energy Center Project (the Project). Hyder Energy Center, LLC, as the Applicant, is proposing the 
construction and operation of an up to 800 MWac electrical generation facility consisting of solar modules 
and energy storage system (ESS), collectively referred to as the Project. The electrical generation capacity 
of the solar (photovoltaic) Project will be up to 800 MWac and the ESS would store solar power for up to 
six hours post-sunset. The Project may be developed in two or more phases. The Project would be located 
on up to 5,634 acres of land in unincorporated Maricopa County, approximately 30 miles west of the Town 
of Gila Bend, Arizona. A large portion of the 5,634 acres is intended to be developed for solar power 
generation and become a unified development (see Figure 1). The table below describes past and current 
land entitlement permitting for both phases of the Project. 
 
Name 
Description 
Size in Acres 
Phase 1 – previously 
approved 
2021 Maricopa County Major Comprehensive 
Plan Amendment (CPA2021011)

2022 Maricopa County Major Comprehensive 
Plan Amendment (CPA2022009) 
2,015 
Combined Project 
Phases 1 & 2 
5,634 
 
Generally, the center of the Project is located at Hyder Road and Agua Caliente Road at (33°02’10”N, 
113°18’23”W). The site is bounded by Butterfield Stage Road to the north, the Gila River to the east and 
south, and the Maricopa and Yuma County boundary to the west. The Project will interconnect to the 500kV 
Hoodoo Wash - Hassayampa line transmission line, located 0.4 miles north of Hyder Road. The Project 
would include up to 1,100,000 solar modules, rated at 655 watts direct current (dc) per module, and 
mounted on single-axis trackers (Figure 1, Detail A). The solar array will reach up to approximately 15 feet 
above ground when fully tilted. In addition to the installation of solar modules, the Project would include 
the construction of a Project substation, ESS, and operation and maintenance (O&M) building located on 
up to 45 acres near the NW corner of Agua Caliente and Hyder Roads and will measure up to 40’ in height. 
All other utilities will be located underground. Minimal lighting will be required for the O&M building and 
ESS. 
The Project will interconnect at (33°02’21.84”N, 113°18’34.85”W) to the existing 500kV Hoodoo Wash – 
Hassayampa transmission lines owned by San Diego Gas & Electric and controlled through the California 
Independent System Operator, located 0.4 mile north of Hyder Road. The existing 500kV transmission lines 
are mounted on tall lattice towers, and no work is anticipated on them. The Project interconnect would be 
a short span, anticipated up to 200 feet in length (Figure 1, Detail B) that would connect to a to-be-
constructed new 500kV tap switchyard, 150-160 feet in height, between two existing lattice towers similar 
to the configuration shown in Exhibit A. The expected maximum net output, at the proposed point of

interconnection from the combined solar modules and ESS is up to 800 MWac. The design life of the Project 
is anticipated to be 40 years.

Good afternoon Ms.Skulstad,
 
The review request for the Hyder Energy Center project is still in process and on schedule.  Federal
law gives us 50 calendar days to respond to informal review requests.  However, we usually
complete them in about 4 weeks or so (depending on the current workload). 
 
I’ll be sure to contact you once the review has been completed.  If you haven’t received anything
from me by Monday, September 26th, please contact me. 
 
Thank you again for the opportunity to review your project.  
 
Respectfully,

Hi Dan:

Thank you for clarifying that. I have checked with our client, the Applicant, who expects anti-
reflective coating to be applied on to the modules at the factory.
 
Please let me know if there is anything else you need from us to start your review.
 
Yours,

Hello Ms. Skulstad,
 
No.  We are just verifying that the panels are/will be anti-reflective as we have recently encountered
arrays consisting of panels that were supposed to be photovoltaic but aren’t doing a good job of
absorbing light.  The glint/glare can sometimes impact new pilots training in the area so we are now
verifying this information upfront. 
 
Our website will soon be updated to reflect this new requirement.  Your tracking is 2022-08-S-DEV-
16 which we will include in our response letter once the informal review has been completed.
 
Thank you for the verification. 
 
Respectfully,
 
Dan Townes

Hi Clearinghouse:
 
Thank you for your prompt response to our request. The panels for this project are photovoltaic
panels meant to absorb light to create energy. Are you asking if the panels are the mirrored kind that
reflect light and concentrate it on a tower? If that is your question, we are NOT installing reflective
panels. The panels are photovoltaic panels meant to absorb light to create energy.

Also, is there a tracking number for our request that we can reference?
 
Yours,

project.
 
I am hoping for an expeditious review as we have applied for a Major Comprehensive Plan
Amendment from Maricopa County, Arizona and have deadlines approaching. May I ask if you can
give me an idea of when your review of our project will conclude?
 
Please let me know if there is anything else you need from me in  order to complete your review.

Dear Ms. Skulstad,  
 
As requested, the Military Aviation and Installation Assurance Siting Clearinghouse 
coordinated within the Department of Defense (DoD) an informal review of the Hyder Energy 
Center Project. The results of our review indicated that the solar project, located in Maricopa 
County, Arizona, as proposed, may have an impact on military operations conducted in the area.  
 
The proposed siting location of the solar project may impact U.S. Air Force (USAF) Air 
Education and Training Command and 56th Range Management Office.  The USAF would like 
additional information regarding the construction of the project.  Please contact Mr. David 
Wilson (david.wilson.123@us.af.mil), Deputy Chief, Air Education and Training Command 
Airfield Operations, to discuss this proposal.  Mr. Wilson will coordinate with other USAF 
representatives and facilitate this informal review process. 
 
Please note that this informal review by the DoD Military Aviation and Installation 
Assurance Siting Clearinghouse does not constitute an action under 49 United States Code 
Section 44718 and that the DoD is not bound by the conclusion arrived at under this informal 
review. To expedite our review in the Obstruction Evaluation Airport Airspace Analysis 
(OE/AAA) process, please add the project number 2022-08-S-DEV-16 in the comments section 
of the filing. If you have any questions, please contact me at scott.e.kiernan.civ@mail.mil or at

Mark, Dobie, and John,
Received the attached email from Ms. Jennifer Skulstad, Senior Project Development Coordinator, and she is  cc'd
in the response.
Followed up with a phone call to Ms. Skulstad earlier to advise the form letter issued by DoD Clearinghouse is a
canned response provided when an DoD unit has questions or concerns about the project.   She requested a follow
on email to support our discussion.
****BREAK, BREAK*****
Ms. Skulstad,
We want to thank the project managers for proactively reaching out through the DoD Clearinghouse to obtain
feedback early in the projects development.
The 19 Air Force Airspace and Range Office nor are Luke AFB Airspace Managers opposed to the Hyder Solar
Project (2022-08-S-DEV-16) but initiated a consult seeking confirmation and support of the following:
1.  To be made aware of the projects construction start and termination dates
2.  To made aware of any cranes being used in the construction to include a height and to request they be lowered at
night or lite if remaining erect overnight.

This information requested is essential to ensure the flight safety of aircraft operations in the airspace we manage
which starts at 100' above the ground of the Hyder Solar Project proposed footprint.
Per discussion, you indicated the projects was not intending to use cranes at this juncture and physical construction
was not due to commence until 2024.  However, to ensure the flight safety of aircraft operating in airspace we
manage, and considering plans do change, wea re requesting Luke AFB Airspace Managers receive notification of
the construction start and termination to allow us to again reconfirm no cranes will be used in the effort.
Luke AFB Airspace Managers Contact Information as follows:

Provided these requests can be met we have no further concerns with the project.
NOTE: Being the informal project was filed through the DoD Clearinghouse which enabled the great folks at the Air
Force Mission Sustainment team (SAF/IEIM) to make use aware of potential impacts from the project.  Our

Mr. Cannon,
 
I have reviewed the Notice of Major Comprehensive Plan Amendment No. CPA2022009 in reference
to the Hyder Solar & Storage Project on behalf of the Arizona Attorney General.  This proposed
Amendment does not have any adverse impact upon Luke AFB nor does it appear to have any
significant impact upon local automobile traffic.  Our office has no objection to this proposed
Amendment.

Hi Jen,
Please see record of conversation below:
Avi Buckles phone call to Peter Steere 9/9/2022 12:15 pm
*Pleasantries exchanged
*Avi discussed prior communication to Peter regarding this matter and encouraged him to request the report from the ASLD.
*Peter indicated ASLD is not very communicative now. I said sorry, they are busy.
*Peter asked me again to send them directly to him--I said I cannot do that. But to help him feel more relaxed about the project I told him no prehistoric sites, just Anglo heritage sites...
*He was happy with that and good wishes exchanged
*End of convo
Thanks!

CPA2022009: Major Comprehensive Plan Amendment - Hyder Solar & Storage Project 
CPA2022010: Major Comprehensive Plan Amendment - Harquahala Sun III 
 
Dear Adam: 
 
Thank you for the opportunity to review and comment on Maricopa County Major Comprehensive 
Plan Amendments CPA2022009 and CPA2022010 for a solar energy projects 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 Hyder Solar and Storage Project is located about 12 miles north of Interstate 8 near the 
farming community of Hyder, AZ. The Harquahala Sun III project is located about 8 miles south 
of Interstate 10 and 18 miles west of the Palo Verde Generating Station. Both projects are located 
in extremely remote areas of the state, with surrounding land uses including scattered agricultural 
lands, solar farms, undeveloped lands, and extremely low density rural residential development. 
 
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. Pima County Development Services 
Department, Planning Division has no opposition to the proposed major comprehensive plan 
amendments.
