3. Proposed Site Conditions
The proposed use is a sand and gravel mine to include batch plant operations, with the southern
portion of the site remaining as open space/natural vegetation. The subject site is approximately 77
acres, 63 acres of which are planned for disturbance through mining. The remaining 14 acres south
of the canal will remain undeveloped open space as it is located within the floodway. The site plan
for the proposed use is shown as Exhibit D, and the extent of the mining pit is shown in the Plan of
Operations (PPO), Exhibit A.
The operation will include wet aggregate mining and materials processing through an on-site batch
plant to provide ready-mix concrete. Excavation will occur throughout the operational life of the
mine in response to the demand for materials. The extraction site will be an open, single, pit area.
Extraction areas will be dependent on the location of the reserves on the site. The details of the
extraction pit are included in the Plan of Operations, Appendix A, and the Floodplain Use Permit
(FUP), Appendix B. Due to the extraction methods and the existing groundwater table, a pit lake will
form in the extraction area. Vector controls will be implemented for the standing water.
The processing area will be initially located on the northern end of the site off of Hazen Road. This is
approximately 4.5 acres, and includes the batch plant and the equipment needed to facilitate the
processing operations. The location of the processing area, as well as the locations of the
stockpiles, will not be permanent and will change throughout the duration of the mine operation to
accommodate the expanding mined pit. All equipment and movements on the site are regulated by
the Mining Safety and Health Administration to ensure safe operations. The placement of
equipment will comply with the City’s setback requirements, as shown on the site plan through the
duration of operations.
There will be no permanent buildings on the site. The height of the batch plant is 60’ and will not
exceed 75’ or 150 square feet in height to remain in compliance with the height exceptions for
structures as regulated by Section 4.2.4.C of the Buckeye Development Code.
The site will have 24/7 operations; however, operational hours may vary depending on volumes of
aggregate. The amount of aggregate that will be extracted is dependent on market demand.
The site design and operations will comply with all applicable air, stormwater, and
hazardous/regulated materials management regulations, including the following:
•
Arizona State Mine Inspector (ASMI)
•
Mine Safety and Health Administration (MSHA)
•
Occupational Safety and Health Administration (OSHA)
•
Maricopa County Air Quality Department (MCAQD)
•
Maricopa County Flood Control District
•
Arizona Division of Occupational Safety and Health (ADOSH)
All governing agencies may suspend operations if the site is out of compliance with their
regulations. Operations will comply with the following permits and plans that have been approved
by County and State agencies:
•
Maricopa County Floodplain Use Permit (Appendix B),
6 |
•
Storm Water Pollution Prevention Plan,
•
Spill Prevention, Control, and Countermeasures Plan,
•
Arizona Department of Environmental Quality Air Quality Permit (Appendix C), and
•
Arizona Department of Transportation Material Source Certification Designation.
These plans and permits are included as appendices.
While the mine is operating, parts of the existing agricultural areas on-site will stay active as
farmland. Farming will continue until the mining operation impacts such areas. Although this is not
standard practice, the owner recognizes that there is a community benefit in keeping the existing
agricultural land until it is needed for mining.
3.1 Design and Landscaping
The design of the site will be regulated by the standards of the Mine Safety and Health
Administration, the Arizona State Mine Inspector, and the Arizona Department of Environmental
Quality. The design of the site post-mining is regulated by the Reclamation Plan, required by the
ASMI, which will be bonded to ensure compliance.
Bermed landscaping will be provided along the Hazen Road frontage as shown on the site plan. The
initial landscaping will be installed on the west side along the Hazen Road frontage. Landscaping
will be within a 20-foot landscaped area and will consist of a three-foot berm with decomposed
granite surface, and trees and other plantings, including mulga trees, purple sage shrubs, yucca as
accents, and lantana as ground cover. Plantings will be one (1) tree and five (5) other plantings per
30 linear feet. The existing agricultural operations will not allow for landscaping on the east side of
the Hazen Road frontage until farming operations are ceased due to irrigation needs. Once farming
operations are concluded, GFT will add similar landscaping and berm in this area. The frontage on
the east side will be installed once that area of the site is converted from farmland to mining land.
Until then, the east side will remain agricultural, which is consistent with the surrounding
characteristics on Hazen Road. The berm along Hazen Road will be constructed based on the Site
Plan.
Signage will be posted at the entrance of the site. This signage will identify the responsible parties
for the mining site and is required by the Arizona Department of Environmental Quality and the
Arizona State Mine Inspector. Signage will comply with the specifications from the Arizona
Department of Environmental Quality and Arizona State Mine Inspector.
There is no permanent site lighting planned for the site. Any lighting will be temporary, as it will be
on equipment in working areas to facilitate the extraction and processing operations. All lighting on
site will be downward facing and will comply with City lighting requirements.
3.2
Accessibility and Circulation
The subject site is located along Hazen Road, which is a Maricopa County arterial. Access to the
site will be through two existing driveway access points off Hazen Road for the duration of the
mining operation. A deceleration lane is planned for turn-in access to the site. This lane is planned
to be constructed on the property, as shown on Exhibit D Site Plan.
7 |
On-site, unpaved roads will be located throughout the site for transport related to the extraction
and processing operations. The internal roads will be temporary and will be reconfigured
throughout the duration of the mining operation to accommodate the progression of the operation.
On-site roads will be maintained by the operator. All on-site roads will comply with the
requirements from the Mine Safety and Health Administration, Arizona State Mine Inspector,
Arizona Department of Environmental Quality, and City of Buckeye. No permanent parking areas
are planned for the site.
3.3
Grading and Drainage
The site is located within the FEMA Effective Floodplain Zone AE. A Floodplain Use Permit (FUP) has
been obtained from the Maricopa County Flood Control District. The FUP Report the details about
the structures that will be constructed as erosion control measures. Such structures will include
an earthen berm on the eastern, southern, and western sides of the site. These structures were
approved through the FUP. A variance for the use of launchable riprap on this property for bank and
toe protection along the Gila River was approved by the City of Buckeye through Variance 26-51-01.
The minable area and the earthen berm are shown in Appendix A Plan of Operations.
All stormwater will be stored in the onsite excavation area. No off-site drainage will be permitted.
3.4
Water and Sewer
Water to the site is provided by an on-site well. Portable solid waste disposal will be provided by a
third-party waste contractor. Portable toilets and related facilities will be located outside of the
setbacks, and behind the landscaping berm, within the processing area, so as to not be visible
from Hazen Road.
3.5
Fire and Police Protection
The site is located 1.4 miles from the Buckeye Fire Station 701 and 2.7 miles from the Buckeye
Police Department Station on Apache Road.
3.6
Schools
The site is within the Buckeye Elementary School District and the Buckeye Union High School
District. The closest school to this site is Buckeye Elementary School and Buckeye Elementary
Preschool, on 7th Street.
4. Reclamation & Future Use
The proposed extraction site is located along the Gila River. Due to the proximity to the river, and
the site’s location within the El Rio District Area Plan study area, the site has potential to contribute
to the City’s vision to reclaim the Gila River in conformance with the City’s Sand and Gravel
Reclamation Guidelines and the El Rio District Area Plan.
The ASMI requires all mining sites to prepare a Reclamation Plan that outlines the reclamation
process for mines once operations cease. A Reclamation Plan for this site was submitted to the
ASMI in August 2025. The Reclamation Plan for GFT Ready Mix is included as Appendix D.
Reclamation of the site will occur concurrently with excavation of the site. The reclamation process
is described in the Reclamation Plan. After mining is completed on the site, it will be designated for
8 |
naturalized open space and a pit lake, as well as natural open space in the undisturbed floodway.
These land uses are consistent with the surrounding properties, which are primarily agriculture and
mining/extraction, as well as the “Neighborhood” and “Open Space” General Plan land use
designations for the site. These uses are also consistent with the post-mining use categories in the
City’s 2015 Sand and Gravel Reclamation Guidelines.
The contents of the Reclamation Plan generally align with Buckeye’s Reclamation Guidelines’
recommended components for reclamation plans. The Reclamation Plan was developed pursuant
to the requirements of the Arizona Aggregate Mined Land Reclamation Rules and in accordance
with House Bill 2685. The Reclamation Plan includes a plan for: the post-aggregate mining use,
regrading and erosion control measures, structures and equipment, on-site road reclamation, and
soil conservation and revegetation on the site. The Reclamation Plan provides a conceptual
schedule for disturbance and reclamation and outlines the estimated costs for the reclamation
measures. GFT Ready Mix is required to bond the estimated costs for reclamation of the property.
Additionally, the El Rio District Area Plan characterizes this site as Rural Agriculture in the preferred
Land Use Character Plan. The ultimate use, as described in the site’s Reclamation Plan, is
compatible with the adjacent recreation/parks and riparian/open space uses, as depicted in the El
Rio District Area Plan.
Another future consideration for the subject site is the proposed SR 30 corridor. The corridor has
not been finalized by the Arizona Department of Transportation; however, the proposed corridor
aligns with the segment of Hazen Road north of the subject property. Future development of SR 30
will therefore likely impact the northern boundary of the subject property.

NOTES
1. THE BERM CONSTRUCTION WITH RIPRAP ARMORED BANK AND LAUNCHABLE RIPRAP TRENCH WILL GENERALLY START
FROM THE EAST AND MOVE WESTWARD. THE BERM WITH RIPRAP AND LAUNCHABLE EROSION PROTECTION WILL BE
CONSTRUCTED IN ACCORDANCE WITH THE FLOODPLAIN USE PERMIT APPLICATION. IT IS WORTH NOTING THAT RIPRAP
PROTECTIONS WILL EXTEND AROUND THE SOUTHWEST CORNER OF THE SITE. THE REMAINDER OF THE BERM ALONG
THE WEST SIDE OF THE SITE IS NOT EXPECTED TO BE EXPOSED TO SCOUR FROM THE GILA RIVER AND WILL BE
UNARMORED PER FCDMC COMMENT.
2. THE BERM WITH RIPRAP ARMORED BANK AND LAUNCHABLE RIPRAP PROTECTING THE EASTERN AND SOUTHERN EDGE
OF THE EAST PIT WILL BE CONSTRUCTED BEFORE ANY MINING CAN OCCUR WITHIN THE DESIGNATED FLOODPLAIN OF
THE EAST PIT. THE BERM CONSTRUCTED ALONG THE SOUTHERN BOUNDARY OF THE EAST PIT MUST INCLUDE THE
EASEMENT BETWEEN THE EAST AND WEST PITS. THE BERM PROTECTING THE WEST PIT MUST BE CONSTRUCTED IN
ADVANCE OF MINING SO THAT ACTIVE EXCAVATIONS IN THE WEST PIT AREA ARE PROTECTED FROM FLOOD FLOWS
FROM THE GILA RIVER. TO ACCOMPLISH THIS OBJECTIVE, MINING IN THE WEST PIT WILL GENERALLY PROGRESS FROM
EAST TO WEST AND BERM CONSTRUCTION WILL ADVANCE NO LESS THAN 500 FEET AHEAD OF THE WESTERNMOST
POINT OF EXCAVATION.
3. EXCAVATION OF SAND AND GRAVEL WILL BE CONDUCTED WITH MOBILE EXCAVATING EQUIPMENT AND HAULED TO
THE ON-SITE PROCESSING PLANT WITH A WHEEL LOADER OR TRUCK UNTIL SUCH A POINT THAT THE PIT BOTTOM
REACHES GROUNDWATER. AT THAT POINT, THE PROCESS WILL SWITCH OVER TO WET AGGREGATE MINING AND
MATERIAL PROCESSING. THE EXCAVATION WILL BE CONCURRENTLY RECLAIMED SO THAT FINAL PIT SLOPES WILL BE
ESTABLISHED DURING THE MINING PROCESS AND NO FURTHER RE-GRADING OR SHAPING WILL BE NEEDED TO
ESTABLISH THE FINAL RECLAIMED SURFACE.
4. VULCAN WILL BE EXCAVATING THE PROPOSED PITS THROUGH THE COURSE OF THE OPERATIONAL LIFE OF THE MINE IN
RESPONSE TO LOCAL MATERIALS ORDERS. THE OPERATIONAL LIFE OF THE MINE MAY INCLUDE SHORT PERIODS OF
INACTIVITY BASED ON DIMINISHING LOCAL DEMAND AND REGIONAL ECONOMIC CONDITIONS. DURING THESE CARE
AND MAINTENANCE PERIODS, VULCAN WILL MAINTAIN APPLICABLE PERMITS AND MONITOR SITE CONDITIONS. DURING
OPERATIONAL PERIODS, THE PIT FACES WILL BE CONCURRENTLY EXCAVATED TO THE FINAL PLANNED PIT SLOPES OF
3H:1V ALONG THE INTERNAL SLOPES IN ACCORDANCE WITH THE APPROVED PLAN OF OPERATIONS AND THE ARIZONA
STATE MINE INSPECTOR (ASMI) APPROVED RECLAMATION PLAN. ONCE THE PITS REACH THEIR RESPECTIVE MAXIMUM
PLANNED DIMENSIONS , VULCAN WILL IMPLEMENT THE REMAINDER OF THE APPROVED RECLAMATION PLAN AND
PERMANENTLY CLOSE THE FACILITY.
5. CLOSURE AND RECLAMATION ACTIVITIES ARE GOVERNED BY THE ASMI APPROVED AGGREGATE MINED LAND
RECLAMATION PLAN (PLAN). THE PLAN IDENTIFIES THE SPECIFIC FACILITY DEMOLITION AND REMOVAL, GRADING,
REVEGETATION, AND SECURITY MEASURES FOR THE SITE TO BE RECLAIMED IN A SAFE AND STABLE CONDITION BEFORE
THE RECLAMATION FINANCIAL ASSURANCE MECHANISM CAN BE RELEASED. THE PLAN GENERALLY REFLECTS THE PLAN
OF OPERATIONS CONTAINED IN THIS APPLICATION.
6. THE PLAN REQUIRES THAT THE SITE BE SECURE, THAT POSSIBLE DRAINAGE INTO THE PITS BE ARMORED TO PREVENT
DAMAGING EROSION, AND THAT THE SITE BE GRADED AND NATURALLY REVEGETATED. THE FINANCIAL ASSURANCE
MECHANISM CAN ONLY BE RELEASED AFTER THE PIT HAS BEEN GRADED AND RECLAMATION MEASURES SPECIFIED IN
THE PLAN ARE IMPLEMENTED.
7. THE OPERATOR IS GENERALLY CONDUCTING CONCURRENT EXCAVATION BY MINING TO THE FINAL PIT SLOPES AND HAS
UP TO 12 MONTHS TO COMPLETE RECLAMATION ACTIVITIES ONCE MINING CEASES, AND THE PLAN STIPULATES UP TO
AN ADDITIONAL 36 MONTHS TO OVERSEE THE SITE TO MONITOR REVEGETATION PROGRESS, ENSURE SLOPE STABILITY,
AND MITIGATE WILDCAT DUMPING. ONCE THE SITE-SPECIFIC RECLAMATION MEASURES ARE IMPLEMENTED, THE
OWNER CAN REQUEST THAT THE SITE BE CLOSED. THE ASMI WILL INSPECT THE SITE FOR COMPLIANCE WITH THE PLAN
AND IF THEY CONCUR THAT CLOSURE AND RECLAMATION ACTIVITIES HAVE BEEN CONDUCTED IN ACCORDANCE WITH
THE PLAN, THEY WILL ISSUE AN OFFICIAL CLOSURE DETERMINATION AND RELEASE THE FINANCIAL ASSURANCE
MECHANISM.
8. IT IS IMPORTANT TO NOTE THAT MINING OPERATIONS CAN ENTER A TEMPORARY CARE AND MAINTENANCE
CONDITION DUE TO MARKET VARIABILITY AND SUPPLY CONSIDERATIONS. DURING CARE AND MAINTENANCE, THE
OPERATOR MUST MAINTAIN AND COMPLY WITH ALL PERMITS, SECURE THE FACILITY, AND CONDUCT ANNUAL
INSPECTIONS AND SUBMIT PROPERTY STATUS REPORTS TO THE ASMI. THE OPERATOR CAN KEEP A FACILITY IN CARE
AND MAINTENANCE FOR NO MORE THAN 5 YEARS AND CAN EXTEND THE CARE AND MAINTENANCE PERIOD ONLY WITH
THE CONCURRENCE OF THE ASMI.
9. MINING OPERATIONS WILL COMPLY WITH RELEVANT MINE SAFETY AND HEALTH ADMINISTRATION (MSHA) RULES AND
REGULATIONS INCLUDING THOSE RULES COVERING POWERED HAULAGE. WHERE REQUIRED, THE MINE OPERATOR WILL
BUILD AND MAINTAIN TEMPORARY SAFETY BERMS ALONG ROADWAYS ADJACENT TO PITS OR OTHER HAZARDS TO
WARN DRIVERS OF THE ROADWAY LIMITS. THE OPERATOR IS PERMITTED TO CONSTRUCT, MOVE, AND MAINTAIN
ROADWAYS AND SAFETY BERMS AS NEEDED TO SUPPORT OPERATIONS AND COMPLY WITH THE APPLICABLE MSHA
REGULATIONS. ANY MSHA BERM SHALL NOT DIVERT AND OBSTRUCT THE FLOW TO CAUSE ADVERSE IMPACT TO THE
ADJACENT PROPERTIES, HOWEVER, THE OPERATOR CANNOT BUILD A PERMANENT MSHA BERM THAT INTERFERES WITH
THE DESIGN AND OPERATION OF FLOOD MITIGATION STRUCTURES DESIGNED AND PERMITTED IN THIS APPLICATION.
NOR CAN THE OPERATOR BUILD ANY PERMANENT STRUCTURE THAT OTHERWISE CAUSES A DIVERSION OF WATER NOT
CONSIDERED IN THIS APPLICATION.
10.FOLLOWING ANY SUBSTANTIVE STORM EVENT, THE OPERATOR IS REQUIRED TO INSPECT AND MAINTAIN BERM
OUTLETS AND PERFORM NECESSARY REPAIRS OR MODIFICATIONS TO ENSURE THAT FLOOD-INDUCED EROSION IS
REPAIRED, AND FUTURE FLOWS ARE PROTECTED FROM EROSION.
DRAFT
CONSTRUCTION SEQUENCING NOTES
1. OPERATOR MUST FOLLOW THE CONSTRUCTION DESIGN AND TIMING BASED ON THE EFFECTIVE FEMA MODEL ENERGY
GRADE LINE (EGL) ELEVATION, AS REQUIRED BY FCDMC. EXCAVATION OF SAND AND GRAVEL WILL BE CONDUCTED
WITH MOBILE EXCAVATING EQUIPMENT AND HAULED TO THE ON-SITE PROCESSING PLAN WITH A WHEEL LOADER OR
TRUCK UNTIL SUCH A POINT AS THE PUT BOTTOM REACHES GROUNDWATER. AT THAT POINT, THE PROCESS WILL
SWITCH OVER TO WET AGGREGATE MINING AND MATERIAL PROCESSING. THE EXCAVATION WILL BE CONCURRENTLY
RECLAIMED, ESTABLISHING THE FINAL PIT SLOPES DURING THE MINING PROCESS TO ELIMINATE THE NEED FOR
FURTHER REGRADING OR SHAPING.
2. THE DESIGN INITIATES WITH THE CONSTRUCTION OF EASTERN PROTECTIONS, INCLUDING A BERM, ARMORED BANK,
AND LAUNCHABLE RIPRAP ALONG THE EASTERN BOUNDARY. THIS BEGINS AT BERM STATION 0+00 AT THE NORTHEAST
CORNER OF THE PROPERTY AND EXTENDS TO THE SOUTHEAST CORNER OF THE SITE AT APPROXIMATELY 20+00.
3. THE BERM AND ARMORING THEN TURN AND CONTINUE WESTWARD UNTIL APPROXIMATELY 31+50, THEN
COMPLETION REQUIRED AT APPROXIMATELY 33+95 BEFORE MINING WITHIN THE PIT CAN COMMENCE. THE BERM
ELEVATIONS AND EROSION PROTECTION MEASURES WILL BE CONSTRUCTED IN ACCORDANCE WITH THE PLAN OF
OPERATIONS, DETAILED IN SHEETS C-101 THROUGH C-300 IN THIS SHEETSET.
4. GFT READY MIX WILL EXCAVATE THE PROPOSED PIT THROUGHOUT THE OPERATIONAL LIFE OF THE MINE, RESPONDING
TO LOCAL MATERIALS ORDERS. THE OPERATIONAL LIFE MAY INCLUDE SHORT PERIODS OFINACTIVITY DUE TO
DIMINISHING LOCAL DEMAND AND REGIONAL ECONOMIC CONDITIONS. DURING THESE CARE AND MAINTENANCE
PERIODS, GFT READY MIX WILL MAINTAIN APPLICABLE PERMITS AND MONITOR SITE CONDITIONS.
5. DURING OPERATIONAL PERIODS, THE PIT FACES WILL BE CONCURRENTLY EXCAVATED TO THE FINAL PLANNED PIT
SLOPES OF 3H:1V ALONG THE INTERNAL SLOPES, IN ACCORDANCE WITH THE APPROVED PLAN OF OPERATIONS AND THE
ARIZONA STATE MINE INSPECTOR (ASMI) APPROVED RECLAMATION PLAN. ONCE THE PITS REACH THEIR RESPECTIVE
MAXIMUM PLANNED DIMENSIONS, GFT READY MIX WILL IMPLEMENT THE REMAINDER OF THE APPROVED
RECLAMATION PLAN AND PERMANENTLY CLOSE THE FACILITY.

A Floodplain Regulation for Maricopa County has been in force since February 25, 1974. The
current version of the Floodplain Regulation for Maricopa County, Arizona was adopted on
August 4, 1986, and amended March 23, 1987, April 6, 1988, September 18, 1989,
September 3, 1991, December 15, 1993, November 1, 2000, December 20, 2006, November
30, 2011, April 9, 2014, June 25, 2014, and January 17, 2018. The intent of the Regulations is
to prevent the dangerous and expensive misuse of floodplains in Maricopa County.
A Floodplain or floodprone area as defined in the Regulations is any land area susceptible to
being inundated by water from any source.
Depending on the location of your property it could possibly be inundated by greater frequency
flood events (those occurring more often). A flood greater in magnitude than the 100-year
flood could also occur.
The review your development has undergone is solely for the purpose of determining if your
application conforms with the written requirements of the Floodplain Regulation for Maricopa
County. It is not to be taken as a warranty. Compliance with this Regulation does not insure
complete protection from flooding. The Floodplain Regulation meets established standards for
floodplain management, but neither this review nor the Regulation take into account such flood
related problems as natural erosion, streambed meander or man-made obstructions and
diversions all of which may have an adverse affect in the event of a flood. You are advised to
consult your own engineer or other expert regarding these considerations.
In consideration for the issuance of the requested permit the applicant, owner, agent, engineer
and their successors agree to hold the District harmless from any onsite or offsite damages of
any kind arising from the development of the subject property in accordance with their
submittals as outlined in the attached permit
I have read and understand the above WARNING AND DISCLAIMER OF LIABILITY.

Mine Plan
The proposed GFT Ready Mix Hazen sand and gravel mine will involve both dry and wet aggregate
mining and materials processing within the 77-acre property. Open pit mining will take place in a single
pit area, reaching a depth of approximately 125 feet, with the pit bottom at an elevation of around
707 feet, according to the North American Vertical Datum of 1988 (NAVD88). The Site will comply with
all applicable air, stormwater, and hazardous/regulated materials management regulations. This
application seeks to provide technical evidence supporting approval for the placement, design, and
operation of this proposed aggregate mine.
4.1
PIT DESIGN
Open pit mining will occur in a single pit reaching a depth of approximately 125 feet, with the pit bottom
elevation calculated as approximately 707 feet (all elevations related to this report and drawings are
prepared using the NAVD88 unless otherwise noted). The proposed mining operation area and the open
pit are located within the Effective Floodplain and outside the Effective Floodway of the Gila River to the
south. The Arlington Canal and proposed berms with launchable riprap erosion protection measures will
separate the active mining area from the Gila River.
The nearest, most recent groundwater measurement data comes from an Arizona Department of Water
Resources monitoring well located on the Site. The well, Groundwater Site Inventory
ID: 332108112365701, had its first depth readings on June 5, 1987; the most recent measurement taken
on January 5, 2018, showed a measured depth to water of 8.8 feet, providing a measured water surface
elevation of approximately 821.2 feet above mean sea level. Given the approximate elevation of the
existing farmland grade of 833 feet, the depth to groundwater in the vicinity of the property is about
9 feet below grade. Consequently, standing water will form a pit lake when excavation activities
intersect the water table. This well data is available within Appendix C.
Since most mining will occur below the groundwater table, leading to the formation of pit lakes,
excavation will be conducted using a dredge or dragline. Unconsolidated sediments at depth will yield
pit slopes no steeper than approximately 3 feet horizontal to 1 foot vertical (3H:1V). The mine plan can
be found as the Proposed Plan of Development (POD) – Sheet C-101, located within Appendix B.
The pit will be protected by an earthen berm constructed around the eastern, southern, and western
sides of the project area.
The main operations area of the Site will be located in various positions, as needed for the operator, for
extraction, stockpile, and transport. Overburden will be temporarily stockpiled around the Site before
being sorted and stored within the main operations area. It will also be used in road and berm
construction or sold as clean fill. Fines from the wash plant will be conveyed to the existing pit lake
formed during the extraction process.
5
5.
Modeling
The Site is located within the Federal Emergency Management Agency (FEMA) Effective Floodplain Zone
‘AE’ as defined on FEMA Flood Insurance Rate Map (FIRM) 04013C2580M, effective February 8, 2024.
The Zone ‘AE’ is identified as a Special Flood Hazard with “The 1% annual chance flood (100-year flood),
also known as the base flood, is the flood that has a 1% chance of being equaled, or exceeded, in any
given year. Base Flood Elevations determined.” An annotated FEMA FIRM of the Effective Floodplain
Zone is included in Appendix D. Historic aerial photographs from 1953 to 2019 verifies that the whole of
the Site is outside of the floodway, see aerial exhibits within Appendix E.
The Effective model was developed using the Hydrologic Engineering Centers-River Analysis System
(HEC-RAS). The model was provided by FCDMC and has been used for the development of the berm
using the energy grade line (EGL) to design the berm top elevations (EGL + 1.0-foot), riprap and
launchable riprap sizing and volumetric sizing based on velocities, water surface elevations, and channel
depths. Output information for the HEC-RAS modeling is provided within Appendix F – HEC-RAS Output
Files.

Erosion and Scour
6.1
LATERAL EROSION AND HAZARD ANALYSIS
The scour analysis developed by WEST Consultants (WEST; see Figure 6-1, below) is detailed in the
Salt/Gila River Sediment Transport Modeling Maricopa County Technical Support Data Notebook
(February 2016). It describes a proposed condition where “other modifications were similar to the
existing condition sediment model geometry. The bank stations were used to limit erosion/deposition
within the main channel for all cross-sections, except those with sand and gravel pits where the limits
were expanded to include the pits. For cross-sections containing the grade control structures, a
maximum erosional bed depth of 20 feet was assumed. For cross-sections with offline pits deeper than
the main channel invert, IFAs were added in the pit at the elevation of the nearest bank station to
prevent the model from crashing” (page 50).
Figure 6-1. WEST Proposed Scour Profile
Additional narrative within the report states, “The total cumulative mass inflow for the Salt/Gila River
system under proposed conditions is shown in Figure 6-28. This figure is similar to the cumulative mass
inflow plot for existing conditions, except at the location of proposed sand and gravel mines, sediment
drops out of the system and causes a drop in the cumulative mass outflow (e.g., near RM 197 and 181).
A smaller amount of sediment is delivered to the SR-85 Bridge (compared to the existing conditions)
because additional sediment is deposited in the proposed sand and gravel pits” (page 74).
Based on the evaluation of the FCDMC comment and sediment transport analysis report, engineering
judgment was used to maintain the ‘Proposed Conditions’ HEC-6T in support of the development of this
Site.
Lateral erosion along the southern and eastern boundaries of the property will be mitigated using an
armoured berm and launchable riprap, as calculated in Drainage Design Management System (DDMSW)
version 6.0.5. The calculation results are located in Appendix G of this application. This modified
proposed plan better estimates the long-term degradation and conditions upstream of the pit. The
resulting long-term degradation per river station is shown in Table 1, below.

BERM DESIGN
The proposed pit will be protected by a flood-protective berm on the south, east, and west sides of the
pit area. The height of which is prescribed by the FEMA floodplain modeling information, applying the
EGL plus 1.0 foot, with 3H:1V side-slopes and a 12-foot top width. The southern and eastern face of the
berm will be protected from any potential erosion by riprap along the berm face, and a measure of
launchable riprap along the southern base. Riprap sizing has been conservatively sized to maintain a
single size and thickness along the whole of the berm.
Launchable riprap will begin at 0+00 in the northeast corner and extend around the Site to the south,
then along the western boundary, ending just beyond the southwest corner at 33+95. Bank riprap will
commence where the berm meets the rising ground at approximately 0+00, and will continue to the
same endpoint as the launchable riprap, terminating at 33+95.
Maximum velocity, minimum thalweg elevation, and maximum total scour for all FEMA cross-sections
were used to calculate the riprap design.
Haley & Aldrich is offering alternatives to the typical angular rock riprap by determining appropriate
alternate sizes based on DDMSW processes and the specific gravity of the material, allowing for the use
of angular concrete rubble. The alternative choices are presented in Table 2, below.

Construction Sequencing and Mine Safety and Health Administration
Berm Requirements
7.1
CONSTRUCTION SEQUENCING
Operator must follow the construction design and timing based on the Effective FEMA model EGL
elevation, as required by the FCDMC. Excavation of sand and gravel will be conducted with mobile
excavating equipment and hauled to the on-site processing plant with a wheel loader or truck until such
a point as the pit bottom reaches groundwater. At that point, the process will switch over to wet
aggregate mining and material processing. The excavation will be concurrently reclaimed, establishing
the final pit slopes during the mining process to eliminate the need for further regrading or shaping.
7.1.1
Pit Sequencing
The design initiates with the construction of eastern protections, including a berm, armoured bank, and
launchable riprap along the eastern boundary. This begins at berm Station 0+00 at the northeast corner
of the property and extends to the southeast corner of the Site at approximately 20+00. The berm and
armouring then turn and continue westward until approximately 31+50, then completion required at
approximately 33+95 before mining within the pit can commence. The berm elevations and erosion
protection measures will be constructed in accordance with the POO, detailed in Sheets C-101 through
C-300 within Appendix B.
GFT Ready Mix will excavate the proposed pits throughout the operational life of the mine, responding
to local materials orders. The operational life may include short periods of inactivity due to diminishing
local demand and regional economic conditions. During these care and maintenance periods, GFT Ready
Mix will maintain applicable permits and monitor Site conditions. During operational periods, the pit
faces will be concurrently excavated to the final planned pit slopes of 3H:1V along the internal slopes, in
accordance with the approved POO and the Arizona State Mine Inspector (ASMI) approved Reclamation
Plan. Once the pits reach their respective maximum planned dimensions, GFT Ready Mix will implement
the remainder of the approved Reclamation Plan and permanently close the facility.
7.1.2
Closure and Reclamation Sequencing
Closure and reclamation activities are governed by the ASMI approved aggregate mined land
reclamation plan (Plan). The Plan outlines the specific steps for facility demolition and removal, grading,
revegetation, and security measures to ensure the Site is reclaimed in a safe and stable condition before
the reclamation financial assurance mechanism can be released. The Plan generally aligns with the POO
included in this application.
The Plan requires that the Site be secured, potential drainage into the pits be armoured to prevent
damaging erosion, and graded and naturally revegetated. The financial assurance mechanism can only
be released after the pit has been graded and reclamation measures specified in the Plan are
implemented.
The operator typically conducts concurrent excavation by mining to the final pit slopes and has up to
12 months to complete reclamation activities once mining ceases. The Plan allows for an additional
36 months to oversee the Site, monitor revegetation progress, ensure slope stability, and mitigate
10
wildcat dumping. Once the Site-specific reclamation measures are implemented, the owner can request
Site closure. The ASMI will inspect the Site for compliance with the Plan, and if they concur that closure
and reclamation activities have been conducted in accordance with the Plan, they will issue an official
closure determination and release the financial assurance mechanism.
It is important to note that mining operations can enter a temporary care and maintenance condition
due to market variability and supply considerations. During care and maintenance, the operator must
maintain and comply with all permits, secure the facility, conduct annual inspections, and submit
property status reports to the ASMI. The operator can keep a facility in care and maintenance for no
more than FIVE years, with the possibility of extending this period only with the concurrence of the
ASMI.
7.2
MINE SAFETY AND HEALTH ADMINISTRATION BERM REQUIREMENTS
Mining operations will adhere to the relevant Mine Safety and Health Administration (MSHA) rules and
regulations, including those covering powered haulage. Where necessary, the mine operator will
construct and maintain temporary safety berms along roadways adjacent to pits or other hazards to
warn drivers of the roadway limits. The operator is allowed to build, move, and maintain roadways and
safety berms, as needed, to support operations and comply with the applicable MSHA regulations. Any
MSHA berm must not divert or obstruct the flow in a way that adversely impacts adjacent properties.
However, the operator cannot construct a permanent MSHA berm that interferes with the design and
operation of flood mitigation structures designed and permitted in this application. Additionally, the
operator cannot build any permanent structure that causes a diversion of water not considered in this
application.
After any significant storm event, the operator must inspect and maintain berm outlets, performing
necessary repairs or modifications to ensure that flood-induced erosion is repaired and future flows are
protected from erosion.

Closing
Haley & Aldrich conducted detailed hydraulic modeling for a proposed mining plan at the GFT Ready Mix
– Hazen Plant, located southeast of the intersection of Arizona State Route 85 and West Hazen Road
near the City of Buckeye. Our efforts included designing a conservatively engineered berm along the
eastern, southern, and western boundaries, with appropriate scour protection using the FEMA Effective
100-year storm event. Our findings included:
Lateral erosion potential along the eastern and southern boundary of the property will be
mitigated with an armoured berm and launchable riprap trench.
No mining or pit protection efforts are intended to interfere with or damage access to the
Arlington Canal.
Launchable riprap and berm have been designed to protect the pit from lateral erosion along
the eastern and southern boundaries, with the riprap sized according to the berm’s position
relative to flows in the Gila River.
No mining will occur in the floodplain of the pit prior to the construction of berms along the
eastern, southern, and western portions of the pit.
In conclusion, the proposed pit has been analyzed within this report, and a workable design concept has
been developed that complies with Maricopa County standards. This concept will provide for the safe
and efficient mining operation while maintaining the integrity of the necessary erosion protection
measures, both existing and proposed. The proposed berm structure will prevent any nominal erosion
or lateral erosion hazard based on the regulatory 100-year storm event, given proper installation and
maintenance. However, deviation from the associated POO, which is based on this report, may nullify
the conclusions within, as may variations in climatic conditions, vegetation, and erosion/deposition.

A Floodplain Regulation for Maricopa County has been in force since February 25, 1974. The
current version of the Floodplain Regulation for Maricopa County, Arizona was adopted on
August 4, 1986, and amended March 23, 1987, April 6, 1988, September 18, 1989,
September 3, 1991, December 15, 1993, November 1, 2000, December 20, 2006, November
30, 2011, April 9, 2014, June 25, 2014, and January 17, 2018. The intent of the Regulations is
to prevent the dangerous and expensive misuse of floodplains in Maricopa County.
A Floodplain or floodprone area as defined in the Regulations is any land area susceptible to
being inundated by water from any source.
Depending on the location of your property it could possibly be inundated by greater frequency
flood events (those occurring more often). A flood greater in magnitude than the 100-year
flood could also occur.
The review your development has undergone is solely for the purpose of determining if your
application conforms with the written requirements of the Floodplain Regulation for Maricopa
County. It is not to be taken as a warranty. Compliance with this Regulation does not insure
complete protection from flooding. The Floodplain Regulation meets established standards for
floodplain management, but neither this review nor the Regulation take into account such flood
related problems as natural erosion, streambed meander or man-made obstructions and
diversions all of which may have an adverse affect in the event of a flood. You are advised to
consult your own engineer or other expert regarding these considerations.
In consideration for the issuance of the requested permit the applicant, owner, agent, engineer
and their successors agree to hold the District harmless from any onsite or offsite damages of
any kind arising from the development of the subject property in accordance with their
submittals as outlined in the attached permit
I have read and understand the above WARNING AND DISCLAIMER OF LIABILITY.

NOTES
1. THE BERM CONSTRUCTION WITH RIPRAP ARMORED BANK AND LAUNCHABLE RIPRAP TRENCH WILL GENERALLY START
FROM THE EAST AND MOVE WESTWARD. THE BERM WITH RIPRAP AND LAUNCHABLE EROSION PROTECTION WILL BE
CONSTRUCTED IN ACCORDANCE WITH THE FLOODPLAIN USE PERMIT APPLICATION. IT IS WORTH NOTING THAT RIPRAP
PROTECTIONS WILL EXTEND AROUND THE SOUTHWEST CORNER OF THE SITE. THE REMAINDER OF THE BERM ALONG
THE WEST SIDE OF THE SITE IS NOT EXPECTED TO BE EXPOSED TO SCOUR FROM THE GILA RIVER AND WILL BE
UNARMORED.
2. THE BERM WITH RIPRAP ARMORED BANK AND LAUNCHABLE RIPRAP PROTECTING THE EASTERN AND SOUTHERN EDGE
OF THE PIT WILL BE CONSTRUCTED BEFORE ANY MINING CAN OCCUR WITHIN THE DESIGNATED FLOODPLAIN. THE BERM
CONSTRUCTED ALONG THE SOUTHERN BOUNDARY MUST TIE INTO THE EXISTING BERM.
3. EXCAVATION OF SAND AND GRAVEL WILL BE CONDUCTED WITH MOBILE EXCAVATING EQUIPMENT AND HAULED TO
THE ON-SITE PROCESSING PLANT WITH A WHEEL LOADER OR TRUCK UNTIL SUCH A POINT THAT THE PIT BOTTOM
REACHES GROUNDWATER. AT THAT POINT, THE PROCESS WILL SWITCH OVER TO WET AGGREGATE MINING AND
MATERIAL PROCESSING. THE EXCAVATION WILL BE CONCURRENTLY RECLAIMED SO THAT FINAL PIT SLOPES WILL BE
ESTABLISHED DURING THE MINING PROCESS AND NO FURTHER RE-GRADING OR SHAPING WILL BE NEEDED TO
ESTABLISH THE FINAL RECLAIMED SURFACE.
4. GFT READY MIX WILL BE EXCAVATING THE PROPOSED PIT THROUGH THE COURSE OF THE OPERATIONAL LIFE OF THE
MINE IN RESPONSE TO LOCAL MATERIALS ORDERS. THE OPERATIONAL LIFE OF THE MINE MAY INCLUDE SHORT PERIODS
OF INACTIVITY BASED ON DIMINISHING LOCAL DEMAND AND REGIONAL ECONOMIC CONDITIONS. DURING THESE CARE
AND MAINTENANCE PERIODS, GFT READY MIX WILL MAINTAIN APPLICABLE PERMITS AND MONITOR SITE CONDITIONS.
DURING OPERATIONAL PERIODS, THE PIT FACES WILL BE CONCURRENTLY EXCAVATED TO THE FINAL PLANNED PIT
SLOPES OF 3H:1V ALONG THE INTERNAL SLOPES IN ACCORDANCE WITH THE APPROVED PLAN OF OPERATIONS AND THE
ARIZONA STATE MINE INSPECTOR (ASMI) APPROVED RECLAMATION PLAN. ONCE THE PIT REACHES ITS RESPECTIVE
MAXIMUM PLANNED DIMENSIONS, GFT READY MIX WILL IMPLEMENT THE REMAINDER OF THE APPROVED
RECLAMATION PLAN AND PERMANENTLY CLOSE THE FACILITY.
5. CLOSURE AND RECLAMATION ACTIVITIES ARE GOVERNED BY THE ASMI APPROVED AGGREGATE MINED LAND
RECLAMATION PLAN (PLAN). THE PLAN IDENTIFIES THE SPECIFIC FACILITY DEMOLITION AND REMOVAL, GRADING,
REVEGETATION, AND SECURITY MEASURES FOR THE SITE TO BE RECLAIMED IN A SAFE AND STABLE CONDITION BEFORE
THE RECLAMATION FINANCIAL ASSURANCE MECHANISM CAN BE RELEASED. THE PLAN GENERALLY REFLECTS THE PLAN
OF OPERATIONS CONTAINED IN THIS APPLICATION.
6. THE PLAN REQUIRES THAT THE SITE BE SECURE, THAT POSSIBLE DRAINAGE INTO THE PIT BE ARMORED TO PREVENT
DAMAGING EROSION, AND THAT THE SITE BE GRADED AND NATURALLY REVEGETATED. THE FINANCIAL ASSURANCE
MECHANISM CAN ONLY BE RELEASED AFTER THE PIT HAS BEEN GRADED AND RECLAMATION MEASURES SPECIFIED IN
THE PLAN ARE IMPLEMENTED.
7. THE OPERATOR IS GENERALLY CONDUCTING CONCURRENT EXCAVATION BY MINING TO THE FINAL PIT SLOPES AND HAS
UP TO 12 MONTHS TO COMPLETE RECLAMATION ACTIVITIES ONCE MINING CEASES, AND THE PLAN STIPULATES UP TO
AN ADDITIONAL 36 MONTHS TO OVERSEE THE SITE TO MONITOR REVEGETATION PROGRESS, ENSURE SLOPE STABILITY,
AND MITIGATE WILDCAT DUMPING. ONCE THE SITE-SPECIFIC RECLAMATION MEASURES ARE IMPLEMENTED, THE
OWNER CAN REQUEST THAT THE SITE BE CLOSED. THE ASMI WILL INSPECT THE SITE FOR COMPLIANCE WITH THE PLAN
AND IF THEY CONCUR THAT CLOSURE AND RECLAMATION ACTIVITIES HAVE BEEN CONDUCTED IN ACCORDANCE WITH
THE PLAN, THEY WILL ISSUE AN OFFICIAL CLOSURE DETERMINATION AND RELEASE THE FINANCIAL ASSURANCE
MECHANISM.
8. IT IS IMPORTANT TO NOTE THAT MINING OPERATIONS CAN ENTER A TEMPORARY CARE AND MAINTENANCE
CONDITION DUE TO MARKET VARIABILITY AND SUPPLY CONSIDERATIONS. DURING CARE AND MAINTENANCE, THE
OPERATOR MUST MAINTAIN AND COMPLY WITH ALL PERMITS, SECURE THE FACILITY, AND CONDUCT ANNUAL
INSPECTIONS AND SUBMIT PROPERTY STATUS REPORTS TO THE ASMI. THE OPERATOR CAN KEEP A FACILITY IN CARE
AND MAINTENANCE FOR NO MORE THAN 5 YEARS AND CAN EXTEND THE CARE AND MAINTENANCE PERIOD ONLY WITH
THE CONCURRENCE OF THE ASMI.
9. MINING OPERATIONS WILL COMPLY WITH RELEVANT MINE SAFETY AND HEALTH ADMINISTRATION (MSHA) RULES AND
REGULATIONS INCLUDING THOSE RULES COVERING POWERED HAULAGE. WHERE REQUIRED, THE MINE OPERATOR WILL
BUILD AND MAINTAIN TEMPORARY SAFETY BERMS ALONG ROADWAYS ADJACENT TO PITS OR OTHER HAZARDS TO
WARN DRIVERS OF THE ROADWAY LIMITS. THE OPERATOR IS PERMITTED TO CONSTRUCT, MOVE, AND MAINTAIN
ROADWAYS AND SAFETY BERMS AS NEEDED TO SUPPORT OPERATIONS AND COMPLY WITH THE APPLICABLE MSHA
REGULATIONS. ANY MSHA BERM SHALL NOT DIVERT AND OBSTRUCT THE FLOW TO CAUSE ADVERSE IMPACT TO THE
ADJACENT PROPERTIES, HOWEVER, THE OPERATOR CANNOT BUILD A PERMANENT MSHA BERM THAT INTERFERES WITH
THE DESIGN AND OPERATION OF FLOOD MITIGATION STRUCTURES DESIGNED AND PERMITTED IN THIS APPLICATION.
NOR CAN THE OPERATOR BUILD ANY PERMANENT STRUCTURE THAT OTHERWISE CAUSES A DIVERSION OF WATER NOT
CONSIDERED IN THIS APPLICATION.
10.FOLLOWING ANY SUBSTANTIVE STORM EVENT, THE OPERATOR IS REQUIRED TO INSPECT AND MAINTAIN BERM
OUTLETS AND PERFORM NECESSARY REPAIRS OR MODIFICATIONS TO ENSURE THAT FLOOD-INDUCED EROSION IS
REPAIRED, AND FUTURE FLOWS ARE PROTECTED FROM EROSION.
CONSTRUCTION SEQUENCING NOTES
OPERATOR MUST FOLLOW THE CONSTRUCTION DESIGN AND TIMING BASED ON THE EFFECTIVE FEMA MODEL ENERGY
GRADE LINE (EGL) ELEVATION, AS REQUIRED BY FCDMC. EXCAVATION OF SAND AND GRAVEL WILL BE CONDUCTED WITH
MOBILE EXCAVATING EQUIPMENT AND HAULED TO THE ON-SITE PROCESSING PLAN WITH A WHEEL LOADER OR TRUCK
UNTIL SUCH A POINT AS THE PUT BOTTOM REACHES GROUNDWATER. AT THAT POINT, THE PROCESS WILL SWITCH OVER
TO WET AGGREGATE MINING AND MATERIAL PROCESSING. THE EXCAVATION WILL BE CONCURRENTLY RECLAIMED,
ESTABLISHING THE FINAL PIT SLOPES DURING THE MINING PROCESS TO ELIMINATE THE NEED FOR FURTHER REGRADING
OR SHAPING.
THE DESIGN INITIATES WITH THE CONSTRUCTION OF EASTERN PROTECTIONS, INCLUDING A BERM, ARMORED BANK, AND
LAUNCHABLE RIPRAP ALONG THE EASTERN BOUNDARY. THIS BEGINS AT BERM STATION 0+00 AT THE NORTHEAST CORNER
OF THE PROPERTY AND EXTENDS TO THE SOUTHEAST CORNER OF THE SITE AT APPROXIMATELY 20+00. THE BERM AND
ARMORING THEN TURN AND CONTINUE WESTWARD UNTIL APPROXIMATELY 31+50, THEN COMPLETION REQUIRED AT
APPROXIMATELY 33+95 BEFORE MINING WITHIN THE PIT CAN COMMENCE. THE BERM ELEVATIONS AND EROSION
PROTECTION MEASURES WILL BE CONSTRUCTED IN ACCORDANCE WITH THE PLAN OF OPERATIONS, DETAILED IN SHEETS
C-101 THROUGH C-300 IN THIS SHEETSET.
GFT READY MIX WILL EXCAVATE THE PROPOSED PIT THROUGHOUT THE OPERATIONAL LIFE OF THE MINE, RESPONDING TO
LOCAL MATERIALS ORDERS. THE OPERATIONAL LIFE MAY INCLUDE SHORT PERIODS OF INACTIVITY DUE TO DIMINISHING
LOCAL DEMAND AND REGIONAL ECONOMIC CONDITIONS. DURING THESE CARE AND MAINTENANCE PERIODS, GFT READY
MIX WILL MAINTAIN APPLICABLE PERMITS AND MONITOR SITE CONDITIONS. DURING OPERATIONAL PERIODS, THE PIT
FACES WILL BE CONCURRENTLY EXCAVATED TO THE FINAL PLANNED PIT SLOPES OF 3H:1V ALONG THE INTERNAL SLOPES, IN
ACCORDANCE WITH THE APPROVED PLAN OF OPERATIONS AND THE ARIZONA STATE MINE INSPECTOR (ASMI) APPROVED
RECLAMATION PLAN. ONCE THE PITS REACH THEIR RESPECTIVE MAXIMUM PLANNED DIMENSIONS, GFT READY MIX WILL
IMPLEMENT THE REMAINDER OF THE APPROVED RECLAMATION PLAN AND PERMANENTLY CLOSE THE FACILITY.

CLOSURE NOTES
CLOSURE AND RECLAMATION ACTIVITIES ARE GOVERNED BY THE ARIZONA STATE
MINE INSPECTOR (ASMI) APPROVED AGGREGATE MINED LAND RECLAMATION PLAN
(PLAN). THE PLAN SPECIFIES THE SPECIFIC FACILITY DEMOLITION AND REMOVAL,
GRADING, REVEGETATION AND SECURITY MEASURES FOR THE SITE TO BE
RECLAIMED IN A SAFE AND STABLE CONDITION BEFORE THE RECLAMATION
FINANCIAL ASSURANCE MECHANISM CAN BE RELEASED.
THE PLAN REQUIRES THAT THE SITE BE SECURE, THAT POSSIBLE DRAINAGE INTO
THE PIT BE ARMOURED TO PREVENT DAMAGING EROSION, AND THAT THE SITE BE
GRADED AND NATURALLY REVEGETATED. THE FINANCIAL ASSURANCE MECHANISM
POSTED WITH THE ASMI CAN ONLY BE RELEASED UNTIL AFTER THE GRADING AND
RECLAMATION MEASURES SPECIFIED IN THE PLAN ARE IMPLEMENTED.
THE OPERATOR HAS UP TO 12 MONTHS TO COMPLETE RECLAMATION ACTIVITIES
ONCE MINING CEASES AND THE PLAN STIPULATES UP TO AN ADDITIONAL 36
MONTHS TO OVERSEE THE SITE TO MONITOR REVEGETATION PROGRESS, ENSURE
SLOPE STABILITY, AND MITIGATE WILDCAT DUMPING ONCE THE RECLAMATION
MEASURES ARE IMPLEMENTED, THE OPERATOR CAN REQUEST THAT THE SITE BE
CLOSED. THE ASMI WILL INSPECT THE SITE FOR COMPLIANCE WITH THE PLAN AND
DETERMINE IF CLOSURE AND RECLAMATION ACTIVITIES HAVE BEEN CONDUCTED

Background
The Flood Control District of Maricopa County (FCDMC) provided an existing HEC-RAS model created in
version 4.1 (United States Army Corps of Engineers, 2010) from Stantec’s Lower Gila River Floodplain
Delineation Study Technical Data Notebook. This FEMA Effective model was used for FIRM analyses,
including the geometry files for cross sections extending from river mile 166.24 upstream to river mile
195.05 (existing conditions), known as Reach 2. The proposed pit is located between river mile 181.22
upstream to river mile 181.44.
Modeling
Cross sections in the existing HEC-RAS geometry file were edited to include the pit at full excavation
(proposed conditions) HEC-RAS modeling was completed using program version 6.6.0 to compare water
surface profile and hydraulic results with existing conditions to results obtained for the proposed
conditions.

Launchable Riprap Design
Checked By: CGL
DESIGN APPROACH
Launchable riprap design is based on the riprap gradation required to provide bank protection should
the Gila River erode laterally to the south and approach the pit. Bank riprap was sized using the Flood
Control District of Maricopa County (FCDMC) Drainage Design Management System Program (DDMSW)
version 6.8.0. This program has a riprap sizing function for river banks and requires the user to input
flow velocity, estimated bank slope, unit weight of rock riprap, and the specific weight of water.
The calculations were taken from output of the Federal Emergency Management Agency (FEMA)
effective previously calculated HEC‐RAS 1D model for the Salt/Gila floodplain. This design was
created with the intent of meeting all FEMA and FCDMC criteria.
PROPOSED DESIGN
The Hazen Site will be protected by a single size of riprap. This design incorporates the maximum
velocities and total scour at cross sections of the FEMA effective model only. The values used in the
calculation of each section of riprap is displayed in Table 1. Please note that the elevations used in
DDMSW have been abbreviated into a single vertical launch distance column in Table 1.

BANK RIPRAP SIZING
The bank riprap was sized using the FCDMC DDMSW computer program for a single straight reach. The
results and riprap gradation for concrete rubble and angular rock, are shown below.

SCOUR COMPUTATIONS
General, Bend, Bedform, Low Flow Thalweg, Local, and Long‐Term Scour were considered based on
procedures and equations found in Sections 11.8.2.1 through 11.8.2.6 of the Drainage Design Manual,
Hydraulics (FCDMC, 2013). Scour was calculated at each cross‐section through the proposed pit using
results obtained from the HEC‐RAS model results (C‐101).
General Scour – General Scour was calculated using the Lacey Equation (Equation 11.56 Drainage
Design Manual). A bend coefficient was not used per comments from the Flood District of Maricopa
County. The Lacey Equation is shown below:
Zgeneral=Z(0.47[Q/f]1/3)
Where:
Zgeneral = general scour depth, feet
Q = Design Discharge, cfs
f = Lacey’s silt factor = 1.75(Dm)1/2
Z = multiplying factor (0.25 for straight reach)
Bedform Scour – The Bedform Scour was calculated using the following equation (equation 11.61 from
Drainage Design Manual):
Z bedform = 0.5dh
Where:
Zbedform = bedform scour depth
dh = dune height (dh=yh*(0.15+0.3)/2)

Low Flow Thalweg Scour – This component of scour accounts for bedform irregularities resulting from the
development of a low‐flow channel. Recommended values range from 1 to 2 feet. A value of 1 foot was
used in the scour calculation.
Local Scour – Local Scour is typically encountered due to obstructions in the flow channel that create flow
acceleration and vortices. Obstructions such as these were not observed in the Gila River channel along
the reach that parallels the southern boundary of the proposed pit. Local Scour was assumed to be 0 feet.
Long‐Term Degradation – Long‐Term Degradation values were obtained from the proposed conditions
HEC-6T model featured in the report “Salt/Gila River Sediment Transport Modeling” (West Consultants,
Inc., 2016).
The 2016 West modeling used a long‐term hydrograph based on historic flow data. The long‐term scour
was found to be quite variable over the reach of the Gila River that flows south of the proposed pit. The
decrease in channel invert elevation (Degradation) or the increase in channel invert elevation
(Aggradation) values were used to determine the maximum long-term degradation at the site

ULTIMATE LAUNCHABLE RIPRAP DESIGN
Launchable riprap was designed using the FCDMC DDMSW computer program. Required program inputs
include total sour depth, riprap D50, main channel velocity, the top of launchable riprap protection
elevation, and the channel thalweg invert elevation. The following table contains a summary of program
inputs assuming rock having a unit weight of 160 pounds per cubic foot. Conservatively the worst-case
scenario with the greatest volume of riprap is to be used in the design. For each section of riprap, the
largest difference between the existing ground and channel thalweg was used from across the FEMA
effective model.
Launchable riprap results are shown below for angular rock and concrete rubble.

Introduction
This Reclamation Plan (Plan) was prepared for the GFT Ready Mix Concrete Company Hazen Plant 4
property (Site) collectively owned by MP Hazen Sand & Rock, LLC and operated by GFT Ready Mix
Concrete Company (GFT) in Buckeye, Arizona. This Plan has been developed pursuant to the format and
content prescribed in the Arizona Aggregate Mined Land Reclamation Rules (Arizona Administrative
Code [A.A.C.] R11-3-101, et seq.). Figure 1 presents the facility location map (Project Locus).
This is a new Plan in accordance with House Bill (HB) 2685. Accordingly, GFT has submitted the required
pre-notification statement of the proposed Plan to each residential property owner whose property is
located within a one-half mile radius of the aggregate mining operation as shown on the current
property tax roll. The submitted letter and locations of each residential structure is presented in
Appendix A.
The Site consists of Maricopa County parcels 400-37-003L and 400-37-003K (identified as MP Hazen
Sand & Rock, LLC) that encompass approximately 78 acres and are located within the floodplain and
floodway of the Gila River. An easement associated with the Arlington Canal splits the northern and
southern parcels (400-37-003L and 400-37-003K) and generally serves as the boundary of the floodplain
and floodway on two parcels. The Site is located southeast of the intersection of Arizona State Route 85
and West Hazen Road within unincorporated Maricopa Country near the City of Buckeye, Arizona. More
specifically, Section 12, Township 1 South, Rance 4 West, and Section 7, Township 1 South, Range 3
West, of the Gila and Salt River base and Meridian. The Site can be accessed from one of several farm
road access points directly from West Hazen Road to the north.
GFT is proposing to:
Excavate approximately 63 acres in the northern and central portion of the Site to create the pit
area.
A concrete ready mix batch plant and aggregate processing area will be located within the
northern portion of the Site until the maximum disturbance is achieved. At this time the
processing plant and concrete batch plant will be moved off Site to another location.

CURRENT OPERATION
2.3.1
Description of Current Operations
The existing Site conditions are shown on Figure 2. Features of the properties include:
Two parcels encompassing approximately 78 acres of developed farmland and undeveloped
land within the floodway of the Gila River.
Three existing buildings including a single-family home and two farm operation buildings. These
buildings will be removed as the mining progresses at the Site.
West Hazen Road provides access at the north end of the property.
The southern parcel is entirely undeveloped and within a Federal Emergency Management
Agency (FEMA) Effective Floodway.
The eastern property line has a chain link fence with access restriction signs.
The Site’s ground surface consists of undeveloped land and active farmland that is generally flat with a
gentle slope to the southeast and elevations ranging from 829 feet to 844 feet above mean sea level
(amsl).
Utilities on the Site include:
Water provided by an active on-Site well;
Power provided by hard-line infrastructure from Arizona Public Service;
Sanitary facilities by a septic system; and
Portable solid waste disposal provided by a licensed third-party solid waste contractor.
2.3.2
Current Permits, Licenses, and Approvals
Operations will comply with applicable air, storm water, and hazardous/regulated materials
management regulations. The properties currently have/will obtain the following permits/plans:
Maricopa County Floodplain Use Permit;
Storm Water Pollution Prevention Plan (SWPPP);
Spill Prevention, Control, and Countermeasures Plan;
Arizona Department of Environmental Quality Air Quality Permit; and
Arizona Department of Transportation Material Source Certification Designation
4
2.3.3
Description of Future Disturbance
All future aggregate mining and reclamation activities on the Site are planned to occur within the
property boundaries (Figure 3).
Excavated materials at the Site will be transported to a separate location once mining advances to the
final disturbance area. Prior to this time, materials will be processed and stockpiled, and a concrete
ready-mix batch plant will operate in the northern portion of the Site. The disturbances to the Site are
estimated to be approximately 63 acres on the property primarily from aggregate mining activities.
The pit is estimated to have a maximum final depth of 125 feet below ground surface (bgs). Pit walls will
be mined to a concurrent reclamation slope of 3 Horizontal to 1 Vertical (3H:1V). The setbacks will be
approximately 50 feet back from the property line to the north, east, and west. The setback to the south
will be greater than 100 feet from the property line due to the Arlington Canal easement and unmined
lands within the FEMA Effective Floodway.
To support mining activities, the Site will maintain temporary unpaved haul roads that lead to the
primary crushing, screening, washing, and stockpile areas (disturbance included in pit disturbance area).
2.4
POST-AGGREGATE MINING USE
2.4.1
Description of Total Future Disturbance
The Site will be designated for two post-aggregate mining land uses including the undisturbed floodway
of the Gila River and naturalized open space and pit lake within the excavated area of the northern
parcel. No part of the reclaimed site will be designated for grazing or forestry.
The Site encompasses a total of 78 acres. Approximately 63 acres will make up the pit, with the
remaining 15 acres on the south end of the property being untouched as it encompasses the Arlington
Canal and property within the FEMA Effective Floodway. The final slope of the pit will be 3H:1V with a
maximum final pit depth of approximately 125 feet.
Lands within the Gila River floodway will remain undisturbed while mining operations occur.
2.4.2
Surrounding Area Land Use
The Site is located on undeveloped farmland in Maricopa County. Surrounding land uses generally
consist of:
Open space dominated by the floodplain of the Gila River to the south;
Developed farmland to the west, north, and east;
Planned or existing aggregate operations to the east and south of the property;
Residential development to the north within 0.5 miles of the proposed pit area; and
Industrial and commercial business directly east of the property.
The planned post-aggregate mining land use as naturalized open space is consistent with surrounding
land uses.

2.5
POST-AGGREGATE MINING REGRADING AND EROSION CONTROL
2.5.1
Description of Final Topography
The final topography for all areas planned to be reclaimed will include pit wall slopes no steeper than
3H:1V for the pit (Figure 4). The pit slopes will be mined to reclamation slopes and therefore no
regrading will be required at closure.
Overburden will be temporarily stockpiled around the Site and used in road and berm construction or
sold as clean fill.
Processing plant material stockpiles will be depleted and removed by the end of the mining operations.
2.5.2
Slope Stability Evaluation
Pit wall slopes will be no steeper than 3H:1V, which is safe and stable according to ASMI. No additional
evaluation is necessary.
2.5.3
Erosion Control Plan
Storm water drainage controls have been established as part of a SWPPP for the Site. Specific erosion
control measures include:
Storm water will be routed into the pit so that no off-Site runoff is anticipated.
Riprap will be used to line drainage points where erosion controls are required.
Earthen berms will be used to prevent outfalls and prevent storm water from flowing off Site.
The SWPPP will be followed in addition to Site-specific best management practices.
2.6
POST-AGGREGATE MINING PLAN FOR STRUCTURES AND EQUIPMENT
2.6.1
Structures to be Removed
The excavation areas will have no permanent post-mining structures. Prior to excavating, GFT will
remove the existing ranch structures on the property. All material processing will occur off Site once the
full extent of the mining excavation is achieved.
2.6.2
Facilities, Wells, and Improvements to be Reclaimed
All improvements, facilities, and aboveground storage tanks will be removed during reclamation
activities.
2.6.3
Access Restriction/Public Safety
Final mining slopes will be graded to 3H:1V for the pit to provide an acceptable factor of safety against
deep-seated failure. Earthen berms will be established around the east, south, and west boundaries of
Site, while a fence will be placed along the northern portion in addition to the existing fence along the
eastern boundary. An active pit, operated by Vulcan Materials, will share the western property line.
Access to the Site from the south will be prevented by the presence of the Arlington Canal. Signs and
other markings will be installed and maintained at any access points to the Site to identify any potential
hazards in an effort to prevent access and ensure public safety.
6
2.7
POST-AGGREGATE MINING ROAD RECLAMATION
2.7.1
Road Description
The Site will contain unpaved roads. These roads will be temporary and change as pit mining progresses.
It is planned that an unpaved perimeter road around the full extent of the mining area will be left in
place for facility care and maintenance after mining and reclamation.
2.7.2
Reclaimed Road Erosion Control Plan
Except for the perimeter security and maintenance road, there will be no roads outside of the pit area.
In the event that mining does not achieve the final disturbance boundaries as shown on Figure 3,
remaining compacted, unpaved, and temporary mining roads within the mining area will be reclaimed
by ripping and scarifying to promote natural revegetation.
2.8
SOIL CONSERVATION AND REVEGETATION
2.8.1
Overburden Conservation Plan
The Site is generally excavated to the final disturbance footprint. However, some overburden will be
retained on Site in berms and stockpiles for future reclamation use, as needed.
2.8.2
Revegetation Plan
Natural revegetation is planned for the Site. The slope areas will be roughened using a grader or
scarified with a bulldozer to provide an appropriate surface to promote natural revegetation.
Care and maintenance of the reclamation effort will involve annual inspections of the Site for three
years maximum. Care and maintenance activities will include monitoring for potential slope movement,
illegal dumping, erosion, and vegetation growth.
Annual inspection reports will be published on the anniversary date of Site closure until the Site is
released by the ASMI.
2.9
CONCEPTUAL SCHEDULE FOR DISTURBANCE AND RECLAMATION
The conceptual schedule includes:
Disturbance operations are ongoing.
Excavation completion of the primary pit area will continue through approximately 2045.
Reclamation activities will be concurrent with excavation activities as conditions allow.
If concurrent reclamation is not feasible, areas will be reclaimed after excavation activities
cease. Final post-aggregate reclamation activities will begin within 12 months of the cessation of
excavation activities and is anticipated to be completed within 12 months.
Reclamation will be deemed complete once the ASMI verifies that the owner or operator has
fulfilled the requirements of the approved reclamation plan.

2.10
PROBABLE FUTURE CONDITIONS
The profitable operation of a mine is based on a variety of factors including the amount and quality of
geologic resources available for extraction, site-specific hydrogeologic conditions, permitting
constraints, economic factors affecting the cost of extraction and processing, and market conditions
which influence the supply and demand for these materials or finished products containing these
materials. Changes to any of these factors can have significant impacts to mine profitability and can thus
require operators to modify mining, processing, or operational methods or expand or temporarily cease
operations.
Further, the means and methods described in this Plan to operate a mining facility and implement
reclamation are based on the application of currently available technologies and practices. These
technologies and practices are constantly evolving, and the operations described in this Plan may be
modified if the currently specified means and methods become outdated, obsolete, cost ineffective, or
impracticable.
Consequently, factors affecting profitable operation or means and methods are likely to change due to
unanticipated or unknown future conditions. Therefore, the operator of the facility described in this
Plan reserves the right to adapt their operations or plans to these changing, unanticipated, or unknown
future conditions to the extent that these operational changes do not cause substantial non-compliance
with existing permits or authorizations.
2.11
ESTIMATED RECLAMATION COSTS
The unit costs developed for this Reclamation Plan are based primarily on the cost estimating database
RS Means Facilities Construction Cost Data (2024) along with estimated productivity for material
movement based primarily on the Caterpillar Handbook (Edition 31). Administrative costs were based
on Arizona Rock Products Association and Haley & Aldrich, Inc. recommendations. Material volumes
were calculated using AutoCAD Civil 3D surfaces for cuts and fills. Surface areas were defined by plan
projection of outlined area.
The estimated costs developed for this Reclamation Plan Significant Amendment include:
Mining Pit Areas regrading;
Plant Area regrading;
Road reclamation;
Structure demolition and removal;
Care and maintenance;
General construction;
Plant removal; and
Administrative costs.
A summary of the estimated reclamation costs are presented in Table I at the end of this section. The
sources and calculation of the estimated reclamation costs are provided in Appendix B.
8
2.11.1 Mine Pit Areas Regrading Cost
The mining area will be excavated to final reclamation slopes of 3H:1V above the estimated pit lake
elevation of 821 feet amsl.
There is no cost for pit wall regrading.
2.11.2 Plant Area Regrading Cost
All remaining stockpiles of merchantable materials will be sold or relocated off Site prior to cessation of
mining or used for regrading. Consequently, no removal of stockpiles will be necessary if the Plan is
executed as written. The plant area is included and will be excavated within the maximum disturbance
area and thus regrading is not anticipated for the area.
There are no costs associated with this category.
2.11.3 Road Reclamation Cost
A perimeter road will be used during the active life of mine and remain afterwards. All roads used during
mining will be in the pit area and be consumed by the pit lake.
There are no costs associated with this category.
2.11.4 Structure Demolition and Removal Cost
It is planned that the three ranch structures and the septic tank will be removed prior to completion of
mining. However, costs have been included to remove these facilities from the property.
The cost for structure removal is $13,000.
2.11.5 Care and Maintenance Cost
Care and maintenance for the reclamation effort at this operation consist of:
Three annual inspections of the Site and preparation of the required annual reports describing
the Site conditions; and
Trash removal.
Three annual inspections are estimated to be needed before the Site is released. Approximately 10 tons
of trash removal is assumed for this category. The cost of care and maintenance of the Site is estimated
to be $24,000.
2.11.6 Construction Cost
Construction efforts for reclamation include:
Installation of a fence and site restriction signs.
The cost of construction is estimated to be $12,300.
9
2.11.7 Plant Removal Cost

To Whom it May Concern:
As you may be aware, GFT Ready Mix (GFT) will be operating the Hazen Plant 4 sand and gravel facility located at 25550
West Hazen Road in Buckeye, Arizona (Site). Our Site will be an import source of high-quality construction materials in
the community. In accordance with Arizona law, GFT has begun the forward-looking process of developing a Closure
and Reclamation Plan (Plan) for the Site. Although we will continue to operate for many years, reclamation and closure
planning is an important long-term process that prepares the Site for an eventual productive post-mining land use.
As we begin this important planning process, we are consulting with the Arizona State Mine Inspector and nearby
residents such as yourself. By developing closure plans through a formal Aggregate Mined Land Reclamation Plan, GFT
can best plan for that future and create a post-mining property use that complements the future growth surrounding
and within the area.
As part of this process, we are delivering this notice to nearby residents. While you don’t have to do anything, you may
request a copy of the proposed reclamation plan from the Arizona State Mine Inspector. Should you have any questions
you can contact GFT by email at jcasey@gftmix.com
Sincerely,
John Casey
Owner, MM

Unit Cost Basis
Equipment rental rates and operator labor rates are based on the RS-MEANS CREWS data, as referenced
for each piece of equipment. The unit rates can be adjusted by the city cost index for specific locations,
however, no adjustment was made since the Phoenix Area rates are close to the national average.
