INTRODUCTION
The City of Buckeye (City) is applying to the Bureau of Land Management (BLM) Hassayampa Field
Office under the Recreation and Public Purposes (R&PP) Act to lease two parcels of BLM-managed land
totaling approximately 640 acres for the purpose of expanding the public trail system and amenities at
Skyline Regional Park.
The existing R&PP lease for Skyline Regional Park is an 8,675-acre mountain preserve in the southern
White Tank Mountains in Buckeye, Arizona, on the western edge of metropolitan Phoenix (Figure 1). It
was developed by the City after entering a 25-year, no-cost lease agreement under Lease #AZA-32053
(01) with the BLM in 2010.
East of the currently leased lands, between Skyline Regional Park and the community of Verrado, are two
BLM parcels totaling approximately 640 acres that are the subject of this Plan of Development (POD).
Both parcels occur in the Sonoran desertscrub biotic community in the foothills of the White Tank
Mountains. Typical plant species include creosote (Larrea tridentata), foothills palo verde (Parkinsonia
microphylla), brittlebush (Encelia farinosa), triangle-leaf bursage (Ambrosia deltoidea), saguaro
(Carnegiea gigantea), teddy bear cholla (Cylindropuntia bigelovii), and buckhorn cholla (Cylindropuntia
acanthocarpa). Both parcels also occur in Desert Tortoise Habitat Management Category 3, which refers
to areas of desert tortoise habitat that are not essential to maintain viable populations.1

This POD describes the design intent for artfully and sensitively arranging trails and trailhead facilities
while minimizing impacts to the natural environment. Supporting infrastructure improvements are
proposed to provide services for restrooms and maintenance and are intended to maintain the natural and
suburban character of the area for the public benefit.
1.1
Background
In 2002, the City submitted an R&PP lease application for approximately 9,315 acres in the southern
White Tank Mountains, south of Maricopa County’s White Tank Mountain Regional Park with the
intention of including all 9,315 acres in Skyline Regional Park. Initial drafts of the City’s environmental
assessment and POD for Skyline Regional Park included the two subject parcels. Additionally, the City
commissioned a Class II cultural survey for the northern parcel and a Class III cultural survey for the
southern parcel, reports for which were submitted to the BLM in March 2006.
However, in 2005 while the City was advancing the POD, DMB – Verrado (DMB), who is developing the
master planned community of Verrado to the east, began conversations with the City regarding the two
subject BLM parcels. At that time, DMB had interest in developing the two subject parcels as an open
space buffer and expansion of several adjacent Verrado neighborhoods. DMB believed the lands suitable
for disposal under Section 206 of the Federal Land Policy and Management Act and was considering a
land exchange with BLM for the two subject parcels with other DMB-owned lands. At DMB’s request,
the City withdrew the two subject parcels from its R&PP lease application, ultimately leasing 8,675 acres
for Skyline Regional Park in its current boundary extent. Also, in response to DMB’s request, BLM
classified the two subject parcels as suitable for sale or exchange in the Bradshaw–Harquahala Approved
Resource Management Plan approved in 2010.2
Over the past few years, DMB has reevaluated the use of the two subject parcels in its future community
plans and believes the lands to be better suited for inclusion in the City’s existing R&PP lease for Skyline
Regional Park. Adding the two subject parcels into the City’s lease agreement will allow the City to
enhance trail connectivity between the existing Skyline Regional Park and its many users coming from
the Verrado community.
1.2
Statement of Need
Buckeye consistently ranks in the top 10 fastest growing communities nationwide (Figure 2).3 In 2000,
the rural farming community had a population of 6,500 residents. In 2010; Buckeye had a population of
51,876, which surged to 91,502 in the 2020 census, for an increase of almost 40 percent, or 40,000 people
over a 10-year period. The City’s 2023 population estimate was 114,000 based on residential permits
issued since the 2020 census data was collected.4 Buckeye is Arizona’s largest city in land area with a
638.8-square-mile planning area and is poised to become one of the largest populated cities in the
Phoenix metropolitan area.5 There are also more than 300,000 proposed dwelling units approved in
various master planned communities within Buckeye, and population estimates show Buckeye to be home

to more than 1.5 million residents at total build out. The Maricopa Association of Governments (MAG)
estimates Buckeye will grow to nearly 460,000 people by 2055.6
Figure 2.
Population growth in Buckeye
The Verrado community on the east side of Skyline Regional Park comprises 8,800 acres and is projected
to include up to 14,080 homes and 4 million square feet of office, light industrial, and retail space at full
build out. The open space that Skyline Regional Park provides is vital to the growing community and
serves as a recreation destination for the entire West Valley area, drawing in thousands of visitors
annually. In 2016, the City installed traffic counters at the main entrance to Skyline Regional Park to
gauge the number of park visitors. Visitation continually increased, and over the following five-year
period, the City estimates visitation grew from 189,000 visitors in 2016 to 425,000 visitors in 2020, about
a 122 percent increase annually. These high visitation numbers demonstrate the desire for mountain parks
and preserves in the West Valley area of metropolitan Phoenix.
Skyline Regional Park currently offers about 22 miles of City-maintained trails for hikers, mountain
bikers, and horseback riders as well as picnic areas and campsites.7 The park also provides support
facilities such as a restroom, programming area, gatehouse, and parking at the trailhead off Watson Road.
Parking demand at this trailhead, however, is starting to outpace the availability of parking stalls
(Figure 3). Visitors accessing the Skyline Regional Park trails from the east side currently park at a
temporary trailhead on Verrado property and use an existing jeep trail through the south parcel to connect
to Skyline Regional Park’s Lost Creek Trail. This popular trailhead, however, will be removed in
Verrado’s next phase of development, leaving the nearest visitor parking access to Skyline Regional Park
via the subject parcels more than a mile away at either Meck Park, a temporary trailhead farther north of
Meck Park, and the Watson Road Trailhead, all of which are already providing other recreational parking
demands. The Canyon Vista Trailhead is also planned in the area approximately two miles from the Lost
Creek Trailhead.

Including the two subject parcels in the City’s R&PP lease for Skyline Regional Park will allow the City
to continue providing trail connectivity to the broader community and will facilitate consistency with
Skyline Regional Park for trail marker signage, emergency trail marker signage, tread surfacing, trail
maintenance, policing, staffing, and volunteerism.

Community Support
The City Council adopted Resolution 21-16 on April 19, 2016, authorizing the submission of an R&PP
lease application to BLM for the two subject parcels east of Skyline Regional Park, which total
approximately 640 acres (Appendix C). The City then filed the R&PP lease application with the BLM in
May of 2016 (Appendix D). This POD builds on that lease application with additional information about
the proposed facilities.
DMB fully supports the City’s efforts to add the two subject parcels into its existing R&PP lease with the
BLM for Skyline Regional Park (see Appendix E for the letter of support from Daniel T. Kelly, Senior
Vice President of DMB Associates).
1.4
Location
The two subject parcels are east of Skyline Regional Park and west of the Verrado community (Figure 4).
Both parcels have existing dirt trails or roads that are currently used by hikers, mountain bikers, and
equestrians. The east side of Skyline Regional Park is accessed off Verrado Way, roughly a mile east of
the two parcels. Additional large undeveloped landowners within a 6-mile radius include BLM, Arizona
State Trust (AST), and the Buckeye Military Reserve.

North Parcel
Figure 5.
View looking north of the north parcel and existing road beyond
The north parcel is mountainous in character, ranging from approximately 1,455 feet to 2,345 feet in
elevation (Figure 6). The site is bounded by Skyline Regional Park on the west and the community of
Verrado to the north, east, and south. The site was once used by Caterpillar, a construction and mining
equipment manufacturer, as a proving grounds for their products. Caterpillar developed a dirt road
approaching the parcel from the east along the Camelback Road alignment. At the southeast corner of the
parcel, the road turns north and runs parallel to and just outside the eastern perimeter of the parcel for
Skyline Regional Park Outlying Parcels R&PP Lease Plan of Development

about 0.6 mile. From there, the road heads northwest, crossing through the north parcel into the White
Tank Mountains. A historical 100-foot-wide right-of-way for the road through the north parcel was
relinquished in 2024 (serial number AZA 001525). The road serves as an alternative access route to
communication sites on top of the White Tank Mountains and as a path for mountain bikers and hikers;
however, the portion of the road on Verrado property will not remain once this area of Verrado is
developed in a future phase of the community. Additionally, a Special Use Airspace zone for Luke Air
Force Base roughly covers the northern third of the parcel.
Figure 6.
Elevational analysis of the north parcel
Most of the parcel exceeds 25 percent grade with a few areas west of the existing dirt road with grades
that are less than 8 percent (Figure 7). While the steep areas may be utilized for trails, facilities that may
accommodate vehicular access or accessible amenities are better suited in the flatter areas of the site to
Skyline Regional Park Outlying Parcels R&PP Lease Plan of Development

minimize grading impacts. The entirety of the north parcel is classified as BLM Visual Resource
Management Class II, which has the objective to retain the existing character of the landscape. The level
of change to the characteristic landscape should be low. Management activities may be seen but should
not attract the attention of the casual observer. Any changes must repeat the basic elements of form, line,
color, and texture found in the predominant natural features of the characteristic landscape.

1.4.2
South Parcel
Figure 8.
View looking west at the south parcel from the Verrado property line
Most of the south parcel is in the foothills zone of the White Tank Mountains, characterized by flatter
terrain segmented by drainage arroyos. Steeper, mountainous topography occurs along the southern
perimeter and in the northwest corner of the site. The site is bordered by Skyline Regional Park to the
west and south and by the Verrado community on the north and east. Verrado is planning to develop
residential lots along the eastern perimeter of the parcel in its next phase of development, along with an
extension of Lost Creek Drive, and is conceptually planning additional residential lots north of the site in
a later phase.
Elevations range from roughly 1,405 feet to 1,920 feet (Figure 9). Most drainage flows east into the
Verrado community though a minor portion of drainage that is directed south from the southwest corner
of the parcel. An existing dirt road, approximately 10 feet wide, runs parallel to and about 250 feet south
of the northern boundary line, connecting Verrado to Skyline Regional Park’s Lost Creek Trail and overall
trail system.

Figure 9.
Elevational analysis of the south parcel
About one-third of the parcel has grades that are less than 8 percent, mostly in the northern half of the
parcel (Figure 10). These flatter areas are better suited for developing trailhead facilities than the steep,
rugged areas to the south and west. Hiking trails are easily adaptable to development in steep terrain,
allowing this portion of the site to be utilized for making trail connections to Skyline Regional Park. The
entirety of the south parcel is classified as BLM Visual Resource Management Class IV, which has the
objective to provide for management activities that require major modifications of the existing character
of the landscape. The level of change to the characteristic landscape can be high. These management
activities may dominate the view and be the major focus of viewer attention. However, every attempt
should be made to minimize the impact of these activities through careful location, minimal disturbance,
and repeating the basic elements.

Site Evaluations
In July of 2024, the City submitted to the BLM two Class III cultural reports, one for the north parcel and
one for the south parcel (Appendices A and B). The surveys evaluated the full parcel extents except where
steep terrain (exceeding 30 percent slope) limited access. The steep terrain area excluded from the surveys
totaled 203 acres in the north parcel and 126.5 acres in the south parcel (Figure 11). In this hilly terrain,
the area was examined from saddles and ridge tops where feasible.
Figure 11.
Areas of steep terrain excluded from cultural surveys
Biological reports evaluating of the subject parcels are underway. The threatened and endangered species
field review evaluated the full area of both parcels except where, similar to the cultural surveys, steep
terrain limited access. Except for proposed trail alignments, areas of the site that exceed 30 percent slope
are not intended for development.

PROPOSED FACILITIES
The site plan concepts shown in the following subsections for the proposed facilities represent what
would be considered the full build out of the subject parcels. During the design process, the proposed
facilities will be developed in further detail to respond to site constraints, comply with applicable zoning
and ordinance requirements in effect at that time, and align with future adjacent development in the
neighboring Verrado community, which is not finalized nor completely defined at this time. However, the
plans shown in this POD have been thoughtfully laid out to work with existing topography to minimize
site disturbance. Potential design or engineering adjustments are not anticipated to be substantial in nature
or extend beyond the biological and cultural surveys conducted in support of this POD. While Verrado’s
future community plans are still in design, the City will work closely with Verrado through its plan
approval process to ensure access and utility accommodations are made for the proposed improvements in
this POD. The proposed facilities shown are intended to be developed over time as funding and
supporting infrastructure become available (see Section 5).
The program for each parcel includes the following elements in different scales and configurations:
◼
Trails to connect to the existing and planned Skyline Regional Park trail network
◼
Trailhead parking
◼
Rest nodes with restrooms, shade structures, seating and site furnishings, and signage
◼
Access roads from the future Verrado road network
◼
Entry features
The south parcel trailhead is intended to be the more developed of the two subject parcels, in part because
it will serve an existing population of trail users that are currently using the temporary trailhead on the
adjacent Verrado property. The flatter topography of the south parcel is also better suited to accommodate
a larger trailhead parking area.
The rugged terrain of the north parcel offers the opportunity for challenging, picturesque trails and a bike
skills area. The smaller scale of the north trailhead facilities suits both the site character and the more
remote location.
The hours of use for the proposed subject parcel facilities will likely follow those currently in place for
Skyline Regional Park. The hours of operation for the Watson Road trailhead are currently from sunrise to
10:00 p.m. due to the presence of campsites; however, the Skyline Regional Park trails are only open
from sunrise to sunset. The City will determine the hours of access to the subject parcels at the time of
opening.
2.1
Trails
Intended Users: The users of the trails will be the general public, including all age groups and varying
physical ability. The adjacent community of Verrado has an active bike community, and it is anticipated
that many mountain bikers will use the trails.
North Parcel Trails Description: The mountainous terrain of the parcel may be well suited for more
physically challenging trails with higher difficulty ratings. The trail shown as a planned Skyline Regional
Park trail on Figure 12 is an existing blazed trail within the Skyline Regional Park boundary that has not
yet been incorporated into Skyline Regional Park trail network as a designated, maintained trail; however,
Skyline Regional Park Outlying Parcels R&PP Lease Plan of Development
Environmental Planning Group, a Terracon Company, June 2025
p a g e
13
when the Skyline Regional Park trail network expands in the future, this trail is planned to be included.
The two proposed trails will connect to the planned trail along new trail alignments to provide better
access to the surrounding community. Drainage crossings will likely be at-grade crossings.
Figure 12.
North parcel trails
Skyline Regional Park Outlying Parcels R&PP Lease Plan of Development
Environmental Planning Group, a Terracon Company, June 2025
p a g e
14
South Parcel Trails Description: The trails in the south parcel are more varied in their topographic
profile and difficulty (Figure 13). The main east-west trail follows an existing two-track road that
connects to Lost Creek Trail in Skyline Regional Park. The trail is characterized by relatively flat terrain
punctuated by steep wash crossings. Most of the crossings would be at-grade crossings, but a pedestrian
bridge is shown at the wash crossing west of the trailhead rest node (Figure 21). The bridge would be
similar in character to the pedestrian bridge at the Watson Road trailhead, though about half the length
(Figure 15). An existing at-grade crossing of the wash south of the proposed restroom will be used as a
secondary crossing. A series of barrier-free loop trails close to the proposed trailhead provide an
accessible trail experience (Figure 14). The remaining proposed trails connect to the existing Skyline
Regional Park trail network south and west of the parcel boundary and range from moderate to difficult.

Park
Design Criteria: The trails are anticipated to be single-track, non-motorized trails for hiking and
mountain biking use consistent with the trails constructed at Skyline Regional Park. The trails will follow
the natural undulation of the topography with minimal cut and fill grading required to achieve a 2- to 4-
foot-tread width and 1- to 2-foot-wide shoulders. More popular trails may be wider, especially when using
existing old jeep trails. Barrier-free trails will have a low level of difficulty and comply with Americans
with Disabilities Act (ADA) requirements for slopes (maximum 5 percent longitudinal slope and
maximum 2 percent cross-slope) and surfacing (concrete, asphalt, chip seal, or stabilized decomposed
granite). Difficult, strenuous trails tend to be narrower as they navigate rocky terrain, and easy to
moderate trails tend to be wider to accommodate a larger number of trail users and range of physical
ability (Figure 16 and Figure 17). Challenge obstacles tailored to mountain bikers, such as drops, jumps,
rock gardens, and or rock rolls may be incorporated into the shared-use trails as short detours off the main
trail (Figure 18). Varying the difficulty level of the challenges creates interest and provides opportunities
for skill progression. Beginner obstacles are usually around 6 inches of height or drop. Intermediate
obstacles would be within the 1- to 3-foot range. Advanced obstacles could be 3 feet or more. All trails
will include directional trail markers at trail intersections and emergency signage posted every quarter
mile.

Trailhead Parking
Intended Users: The day-use trailhead areas will provide vehicular parking for trail users of all ages that
live too far to comfortably walk or bike to the proposed trails. While the trails are intended to be shared-
use for hiking, mountain biking, and equestrian, the parking shown is not intended to accommodate
equestrian trailers since trailer parking is already available at the main Watson Road trailhead.

North Trailhead Parking Description: Situated west of the existing excavated pit on the adjacent Verrado
property on one of the flatter areas of the site, the north parcel trailhead parking is shown on Figure 20 as
58 total stalls grouped in six bays along the singular access drive extending from the Verrado residential
community to the turnaround at the rest node, though the exact number and configuration of parking stalls
will be determined during design. The parking islands between the bays are sited at existing drainage
Figure 20.

washes to support landscape in the islands and minimize the length and impact of drainage crossings. The
parking bays may be constructed in a later phase after the rest node and access road have been added so
that the City can gauge whether parking is needed at this location or if most of the trail users are walking
or cycling to the trails from the adjacent neighborhoods. The turnaround at the end of the parking aisle is
intended to provide the necessary turning movements for larger emergency-access vehicles. It is
important to note that the road location, alignment, and connection into Verrado is schematic as Verrado’s
development layout is not known at this time.
South Trailhead Parking Description: The south parcel trailhead is shown on Figure 21 as 48 initial
parking stalls with room for 78 additional parking stalls that may be added in a future expansion if
parking demand and public interest warrant. The final layout and number of parking stalls will be
determined during design. The drive aisles are designed to accommodate turning movements of large
emergency vehicles around the outer loop of the parking. The large parking islands between drive aisles

South parcel site plan concept
Skyline Regional Park Outlying Parcels R&PP Lease Plan of Development

are intended to help screen parking views from future residential lots and to collect and distribute
rainwater from the parking and drive surfaces to preserve the existing vegetation.
Design Criteria: The parking area will accommodate standard vehicle sizes (e.g., sedans and pickup
trucks) and include accessible parking stalls in accordance with ADA and City standards in place at the
time of permitting. The parking bays on both sites are aligned roughly parallel to the site contours to
minimize longitudinal slopes along the bays, thereby facilitating the accommodation of accessible routes
to the rest node facility with less grading impact. The parking layout shown is configured with
perpendicular parking stalls that are 9.5 feet wide by 20 feet long and two-way drive aisles that are 24 feet
wide in accordance with current City requirements; however, these dimensions may be slightly modified
during design to reflect changes in programming or permitting requirements.8 The trailhead parking area
will feature asphalt surfacing, for which the thickness and subgrade preparation will be based on
geotechnical recommendations made during the design phase. The parking stalls designated as accessible
may be paved in concrete to aid in visual contrast (Figure 19). The parking edging may incorporate a
combination of flush curbs with mounted wheel stops or vertical concrete curbs with curb openings at
drainage outlets based on MAG Standard Details 220 and 2229 and the Greater Phoenix Metro Green
Infrastructure Handbook Standard Details LID-02 and LID-0310 (or similar) to direct stormwater runoff
into adjacent landscape areas for rainwater harvesting and first-flush treatments. Boulders may be used in
lieu of wheel stops to designate the end of the parking stall. Low retaining walls may be incorporated in
sections to minimize site disturbance of cut-fill operations and preserve existing vegetation.
2.3
Rest Nodes
Intended Users: The rest node will consist of a restroom, shade structure, seating, and signage to serve
trail users (Figure 22, Figure 23, and Figure 24). It will serve as a resting place where people can wait for
Figure 22.

2.3.1
Restrooms
Description: The restrooms at the north and south parcels will present a consistent architectural character
to the restroom at the Watson Road trailhead, whether they be customized prefabricated buildings or fully
customized architectural designs (Figure 25). The restrooms shown on the site plans (Figure 20 and
Figure 21) are the same size as the Watson Road trailhead, which accommodates two men’s and two
women’s toilet fixtures as well as storage space. The restrooms will meet current applicable building and
accessibility standards at the time of permitting. The number of toilet fixtures and sinks will be
determined during the design process and will be based on estimated demand, though the building
footprint will be close to what is shown. The restrooms at both the north and south parcels may be vault
toilets, on septic systems, or connected to Verrado’s sewer network. Since Verrado’s sewer engineering is
Skyline Regional Park Outlying Parcels R&PP Lease Plan of Development
Environmental Planning Group, a Terracon Company, June 2025
p a g e
24
unknown at this time, the restroom will connect to Verrado’s infrastructure if feasible. The preference for
supplying water to the developed areas for hand washing sinks and flushable toilets would be to connect
to Verrado waterlines; however, the City may opt to truck in water to be stored in large tanks. If the water
supply is connected to the Verrado service lines, the City may incorporate drinking fountains into the
restroom building or provide them as freestanding units with jug fillers. For the electric service, if not
connected to electric utility lines in Verrado, solar panels may be installed on the restroom roofs to
provide power for low-level security lighting, hand dryers, and maintenance equipment similar to the
Watson Road trailhead (Figure 26). Lighting will be shielded per the State’s dark sky ordinance
ARS 49-1101 to 49-1106.

2.3.2
Shade Structures
Description: The shade structure will be either a custom cantilevered, weathered steel structure to match
the picnic ramadas at the Watson Road trailhead or a manufactured shade structure product with a
comparable aesthetic (Figure 27). The shade structure shown on the site plans (Figure 20 and Figure 21)
is 12 feet by 20 feet; however, the size and configuration will be determined in the design phase. The
trailhead may close at sunset, but the shade structures will include low-level lighting for security.
Figure 27.
Watson Road trailhead picnic ramadas
2.3.3
Seating and Site Furnishings
Description: The seating is envisioned as cast-in-place concrete under the shade structure and, where
possible, near existing trees to match the weathered, board-form finish of the seat walls at the Watson
Road trailhead (Figure 28). These concrete seat walls are intended to be used in lieu of manufactured site
furnishing products like picnic tables or benches; however, the seating may be modified during design to
best fit the site needs and configuration. Support furnishings, such as waste, recycling, and pet waste bag
dispensers, will also be included (Figure 29).

2.3.4
Signage
Description: The signage will include wayfinding maps, general information about the area, and
important considerations for safe trail use. The signage may include a centralized kiosk and individual
signs at the start of the trails similar to signs already installed at the Watson Road trailhead (Figure 30).
The City’s “Happy Trails” Checklist signs currently at the Watson Road Trailhead include information
about heat-related safety considerations for trail use and will be added near the start of trails on the
subject parcels along with notices for heat advisories and fire bans at trailheads. Interpretive signage will
also be added to provide information about the historic and prehistoric context of the site as well as about
native flora and fauna.

2.4
Access Roads
Intended Users: The vehicular access road to the north parcel trailhead may be used solely by park staff
and emergency services if public parking is ultimately not needed or desired at this location. The
vehicular access road to the south trailhead will be open to the public during the hours of operation and
open to park staff and emergency services both during and after hours of operation. Both trailhead access
roads will include walkways that will serve residents in the vicinity going to the sites on foot.
North Parcel Access Road Description: The Verrado community residential areas shown on the
conceptual site plan (Figure 20) east of this parcel are conceptual in nature and have not yet been platted
so the exact connection alignment from the north trailhead access road to the Verrado street network
would have to be engineered after Verrado’s street rights-of-way in the vicinity have been dedicated. It is
anticipated that the streets planned in this area will be two-way local streets that may terminate in a cul-
du-sac. The access road connection as shown on the site plan may shift north or south of where it is
shown, but the access road will keep a similar north-south alignment along most of its length. The City
will work with Verrado during platting to ensure adequate accommodations are made to access the north
parcel by vehicle and include signage indicating users are leaving Verrado and entering Skyline Regional
Park. Regardless of where the connection point ultimately ties in, the access road will need to cross one
wash that runs between the east property line and a parallel existing dirt road. The wash crossing may be
an at-grade crossing or an all-weather culvert crossing, depending on anticipated drainage flows, available
funding, and considerations for future maintenance needs.
South Parcel Access Road Description: The south parcel trailhead will extend from Lost Creek Drive, a
collector street with a wide median that will be extended west from its current terminus northeast of the
parcel boundary by Verrado in its next planned phase of expansion (Figure 21). The City is working with
Verrado to align the access road intersection at Lost Creek Drive to avoid directing headlights into
residential properties on the opposite side of the street. The City will post signage indicating users are
leaving Verrado and entering Skyline Regional Park. The access road will cross a significant wash that
may be bridged, culverted, or crossed at grade depending on drainage engineering recommendations,
available funding, and considerations for future road maintenance needs (Figure 32 shows an example of
a low-water culvert crossing). Construction of the crossing may require cultural monitoring along the
wash terraces during ground disturbance activities.

Design Criteria: The drive lanes and turn radii will be designed to facilitate the two-way driving
movements of the public’s vehicles along with emergency and service vehicles that need access to the
trailhead parking areas and the associated facilities. The access roads will be engineered to:
◼
Comply with the City’s geometric design criteria for rural and hillside streets11
◼
Accommodate site drainage and topography
◼
Fit the available budget
◼
Factor in the anticipated life cycle and maintenance needs of the road
The access road will be paved with asphalt over a structural subgrade based on geotechnical and
engineering recommendations. The road may or may not feature curbing, depending on drainage needs.
The curbing is drawn on the site plans as flush ribbon curbs per MAG Standard Detail 220-1 Type B to
allow stormwater to pass easily into adjacent landscape areas, but it could also be vertical curbs per MAG
Standard Detail 220-1 Type A or Detail 222. If vertical curbs are used, it is recommended that curb
openings per the Greater Phoenix Metro Green Infrastructure Handbook12 Standard Details LID-02 and
LID-03 (or similar) be integrated at regular intervals in accordance with the grading and drainage plans to
distribute runoff more evenly into surrounding landscape areas.
2.5
Entry Features
Intended Users: The entry features will consist of entry monument signage and a vehicular control gate.
The entry signage will serve the public and emergency services in a wayfinding capacity to define arrival
at the park. The gates will be operated by park maintenance staff and, after park hours, notify people that
the park is closed. Police, fire, and rescue personnel will also operate the vehicular gates should an
emergency occur in the area after hours. Additional signage may be posted indicating users are leaving
Verrado and entering Skyline Regional Park.
2.5.1
Entry Monument Signage
Description: The entry monument will be either consistent with the Watson Road trailhead or wayfinding
signage within the Verrado community (Figure 33) in terms of aesthetic style and material selection. The
entry monuments for both parcels will likely occur outside the parcel boundaries at the access road
intersections to Verrado’s streets. The signage will be scaled proportionately to the roadway context
(i.e., the south parcel signage along a collector road may be larger than that of the north parcel sign if that
sign is along a local neighborhood street). Both entry monument signs shall include the address for their
respective facilities to aid emergency services and the public in wayfinding.

Vehicular Control Gates
Description: Where the Watson Road trailhead features a gatehouse with rolling gates, the vehicular
control gates for the two subject parcels will likely be simpler in construction, such as swinging gate arms
with locking posts. Aesthetic consistency could be achieved by using similar weathered steel panels on
the gate arms (Figure 34). As at the Watson Road trailhead, no park entrance fee is intended for use of the
sites’ recreational facilities. The gate locking system will be designed to allow any one of multiple

Bike Skills Area
Intended Users: The bike skills area is intended for riders ranging in skill level from beginner to
advanced as well as spectators. The adjacent community of Verrado has an active bike community, and it
is anticipated that many mountain bikers will use the bike skills course.
Figure 35.
Sedona Posse Grounds Park pump track with preserved vegetation
Description: The bike skills area would utilize the varied terrain of the White Tank Mountains foothills to
offer a variety of bike recreation opportunities, such as pump track style courses, BMX challenge courses,
flow trails, mountain bike trails ranging in difficulty, and training areas for beginners. Surface track
materials could include concrete, asphalt, native dirt treated with a dust palliative, and exposed rocky
outcroppings. Challenge features may include jumps, skinnies, and wall rides. The bike skills trails and
challenges would be sited so that large pockets of natural desert vegetation would remain in place to
preserve the character of the setting. Shaded seating areas may be incorporated as respite areas for riders
and as viewing areas for spectators. As part of the City’s regular maintenance activities, the ranger staff
will inspect the facilities and identify wildcat trails being created by users and block them off with
boulders and vegetation.

PROJECT INFRASTRUCTURE
Currently, there are limited infrastructure improvements in the immediate area of the two subject parcels.
As more homes are developed in the surrounding community, the demand for trail and recreation services
will increase as will the availability of utility services. The City will continue to coordinate with Verrado
through the permitting process to ensure the necessary utility access and engineering criteria will be
incorporated into its development plans to meet the City’s needs for the subject parcels. To reduce
disturbance while still providing reasonable access for repairs to utility lines, it is recommended that
utilities be buried next to the edge of the access drives.
3.1
Water Service
Water, particularly potable water, is a precious resource in the desert. The City currently pays to have
water delivered to the Watson Road trailhead where it is stored in a 5,000-gallon underground tank for use
in the restroom (Figure 36). During the height of the winter visitor season, the tank is refilled two times a
week. As the ongoing maintenance of this process is costly, the City would prefer to connect to waterlines
in the Verrado community when they are expanded with Verrado’s road network. Digging an onsite well is
another water delivery possibility; however, the expense and uncertainty of well exploration and Arizona
Department of Environmental Quality restrictions on groundwater pumping make this alternative
unlikely.

3.2
Electric Service
While it may be possible to connect to future electric lines as Verrado develops, the power requirements
of the proposed facilities are low, primarily limited to hand dryers and security lighting for the restroom
and shade canopies, which can be supplied through onsite solar panel generation.
3.3
Sewer Service
The graywater from handwashing sinks and, potentially, drinking fountains as well as the wastewater
from toilets can be directed to:
◼
Sewer lines in the Verrado community
◼
Septic systems onsite with leach fields
◼
Vaults where the waste would be periodically pumped out and hauled offsite
For both the north and south site plan layouts, gravity sewer lines connecting to the Verrado sanitary
sewer lines are not possible as existing wash crossings and force sewer lines with lift pumps are
maintenance intensive. Septic systems with leach fields provide an alternative sewer option that addresses
wastewater onsite as was done on the Watson Road trailhead. The City and their utility design consultant
will need to evaluate the costs and benefits associated with the options to determine the best alternative
for the given site and budgetary conditions.
3.4
Site Operations
Site operations for both parcels will be based at the Skyline Watson Road trailhead in terms of
maintenance yard space and storage. Trash enclosures and dumpsters will be located at both the north and
south parcel for collected trash. The subject parcels will not have a separate onsite operation base, though
storage space for incidentals may be incorporated into restroom buildings.
The Verrado community has been an active partner with the City in ensuring trail users respect the land
and park rules. Many Verrado community members currently use the existing trails and are helpful in
notifying the City of issues that require maintenance or enforcement.

SUMMARY OF SITE IMPACTS
The site plans shown (Figure 20 and Figure 21) sensitively minimize the footprint of the proposed
facilities to increase users’ enjoyment of the site and limit disturbance to natural habitat. The proposed
facilities have been laid out to scale in AutoCAD on the compiled base topography. The objective of the
park design is to lay lightly on the site to minimize impacts to the beauty of the natural desert
surroundings. To account for disturbance for associated grading and construction activities outside the
trailhead facility footprint (parking, access roads, rest nodes, bike skills area, and barrier-free trail area), a
30-foot offset was used to approximate the average disturbance along the perimeter. This disturbance area
is shown in dark green on Figure 37 and Figure 38.
Figure 37.
North parcel site disturbance area
Skyline Regional Park Outlying Parcels R&PP Lease Plan of Development
Environmental Planning Group, a Terracon Company, June 2025
p a g e
35
Figure 38.
South parcel site disturbance area
The ultimate configuration of the facilities may shift slightly within this disturbance area during final
design to allow for modifications needed to accommodate site conditions and engineering requirements
that may arise when designing to a more accurate, surveyed topographic base file. While the facility
layouts may be modified slightly, the amount of disturbance is intended to be comparable. The facility
area for the non-barrier-free trails is calculated as a 50-foot buffer on both sides of the proposed trail
alignments (Figure 12 and Figure 13).
The site impact calculations listed in Table 3 for the north parcel and Table 4 for the south parcel include
both the proposed disturbance area of both the trailhead facilities and the trails. Areas within the proposed
facility footprint that are already disturbed are then subtracted from the facility footprint.

CONSIDERATION OF AN ALTERNATIVE
The facilities and infrastructure proposed for development as described in Sections 2 and 3 represent the
City’s Preferred Alternative. They are in keeping with the character of the site and adjacent land uses and
reflect recreational needs and interests of the surrounding community as voiced by residents. For the
purposes of exploring an alternative development option, the site plans shown on Figure 20 and Figure 21
have been modified below to show a reduced scope of the improvements for the BLM’s consideration.
In the north parcel, two parking bays have been eliminated (24 parking stalls) and the bike skills area has
been reduced in size. The access road remains as it is critical to providing emergency services. The rest
node remains unchanged as it provides a welcome respite for users and provides the City the opportunity
to post important trail and hazard information at the beginning of the trails. The same trails have also been
included in this alternative as they are the primary recreational use for most visitors.
Figure 39.

In the south parcel, the alternative proposal reduces the scope of the parking by 31 parking stalls but
preserves the trails, rest node, access road, entry feature, and infrastructure.
Figure 40.
South parcel alternative site plan concept
While these options may meet the needs of current park visitors and reduce the proposed disturbance by
1.6 acres to the north parcel and 0.6 acres to the south parcel, the City would prefer to plan for the full
buildout of facilities to accommodate the growing need for outdoor recreation amenities in Buckeye (see
Section 1.2 for the project’s Statement of Need).

PHASING RECOMMENDATIONS
The long-term objective of the City will be to improve the two park parcels to provide public recreational
opportunities that support and enhance Skyline Regional Park. The funding and resources needed for the
implementation, operation, and maintenance of the subject parcels will have to be approved and
incorporated in the sequential funding structure of the City. This, along with the anticipation of future
Verrado expansion to provide street and utility infrastructure for the facilities, will necessitate developing
the trailhead facilities in a series of phases over an extended period. The City does not intend to build the
facilities before Verrado has developed its roadway and utility improvements. Improvements may be
phased beyond 25 years or may be advanced sooner depending on the City’s capital improvement funds
forecasting.
It is likely that the full build out of improvements for the south parcel will be achieved before starting
development of the north parcel. The exception to this assumption is the expanded parking to the south,
which would only be built if public demand for parking exceeds the capacity of the initially provided
parking area and the resulting parking overflow causes a nuisance for neighboring residents. The need and
timing for the expansion is not known and is partially dependent upon Verrado’s continuing and future
development.
Additionally, some facilities may be phased to implement improvements over time. For example, an
initial trailhead development may include vehicular access and parking that are rustic, chip-sealed graded
roadbeds during the initial construction phase. Over time as funding becomes available and as user
demand increases, the chip-sealed roadways may be paved with asphalt as an improvement to enhance
user experience and reduce maintenance.
The phasing priorities outlined below represent the anticipated order of buildout, though the City may
modify this sequence or combine phases to respond to availability of infrastructure, requests from the
public for specific amenities, and available funding.
6.1
Priority Level 1: South Parcel Access Road, Utility
Lines, and Parking
Because Lost Creek Trail already connects Verrado to the Skyline Regional Park trail network via an
existing two-track dirt road, the highest priority after trail access for this parcel is vehicular access,
particularly to meet public demand for parking with the nearby temporary Verrado trailhead that is soon to
be removed. The construction would also include underground utilities aligned under the drives, even if
the restrooms using those utility connections are constructed in a latter phase. Some basic wayfinding
signage at the Lost Creek Drive intersection and at the start of the trails would also be needed.
6.2
Priority Level 2: South parcel rest node
Once vehicular access is provided, the demand for features that increase comfort and enjoyment of the
site will become important to trail users. While it is possible that the south parcel trails may take
precedence over the restroom and rest node, it is foreseeable that the proposed trails shown on Figure 13
that follow existing two-track and single-track trails will sufficiently serve the needs of trail users in their
current state, and may, therefore, be delayed to a future phase.

Environmental Planning Group, a Terracon Company, June 2025
p a g e

6.3
Priority Level 3: South parcel trails
As access to the site is improved, improving the conditions of existing two-track and single-track trails
already onsite will help park staff provide consistency in the level of service provided across Skyline
Regional Park. It will also provide better access to emergency responders in case of emergencies.
6.4
Priority Level 4: North parcel trails
The trails in the north parcel can be constructed and used whether or not additional improvements are
made to the north parcel at the same time. The proposed trails can connect to an existing unimproved trail
through Skyline Regional Park west of the subject parcel and be accessed on the Verrado side by nearby
residents that can walk or cycle to the trails via existing dirt roads. It is possible that the trail construction
for both the south and north parcels could be combined into one phase to reduce the cost associated with
multiple mobilizations for the trail contractor.
6.5
Priority Level 5: North parcel access road, utility
lines, and parking
This phase would be timed to occur after the Verrado streets near the east side of the north parcel property
line have been constructed and utilities extended for the City to connect to. Until that time, park staff
would continue to use existing dirt roads to access this parcel. The parking bays shown along the access
drive in the site plan would likely be constructed as part of this phase if they are deemed an appropriate
use at this site, though they could be developed in a later phase.
6.6
Priority Level 6: North parcel rest node
The rest node at the north parcel could be added to provide similar access to comfort amenities to those
provided at the south parcel.
6.7
Priority Level 7: North parcel bike skills area
The final buildout component would likely be the bike skills area at the north parcel. This feature would
be built if there is enough community support for this type of amenity. It could also be scaled back
depending on interest.

COST EVALUATIONS
Order-of-magnitude cost evaluations are presented to provide a high-level overview for budgetary
planning purposes with the understanding that prices may vary significantly depending on the options
selected for a particular line item (e.g., electric line vs. solar power) and economic fluctuations over the
term of the lease. The order-of-magnitude cost evaluations are broken out separately for the south parcel
(Table 5), north parcel (Table 7), and south parcel parking expansion (Table 9) and reflect the City’s
Preferred Alternative and the phasing priorities discussed in Section 6. The annual project cost escalations
that follow each of the three cost evaluations (Table 6, Table 8, and Table 10) span the 25-year lease and
are intended for City budgetary planning purposes.

MANAGEMENT PLAN
The management of the proposed facilities will be the responsibility of the City’s Community Services
Department. Emergency services for the park are intended to be provided by the Buckeye Police
Department and Fire Department. The City will commit to maintain the area by:
1. Annexing both parcels from unincorporated Maricopa County.
2. Maintaining the subject property, which is open to use by the public, without discrimination or
favor.
3. Developing and managing the lands in accordance with the POD as submitted in the R&PP
application. Any proposed changes to the POD will be sent to BLM for review and concurrence.
The City will provide final development plans to the BLM for review prior to commencement of
construction activities. Depending on the modifications made during final engineering, a separate
NEPA review may be required if the area impacted is not covered by the current Environmental
Assessment.
4. Maintaining the facilities on the parcels in satisfactory condition.
5. Charging no more than reasonable fees for the use of the facilities (whether by concession or
otherwise) and charging no more for entrance than is charged at other comparable facilities
managed by state and local agencies. All charges will be subject to review and modification by
the Secretary of the Interior under due process procedures.

*PARTIAL
The lease of the land herein described is subject to the following conditions:
A.
The lease is subject to City of Buckeye (Lessee) compliance with all applicable regulations
contained in Title 43, Code of Federal Regulations, Parts 2740 and 2912.
B.
The Lessee shall develop the leased lands in accordance with the approved Plan of Development
(POD) and Environmental Assessment (EA) and shall avoid sensitive resources. Any
modifications not analyzed in EA require prior approval from the Bureau of Land Management
(BLM).
1. Any significant deviation from the POD requires prior written approval from the BLM
Authorized Officer (AO).
C.
The Lessee will follow the BLM Phoenix District Office’s (PDO’s) Integrated Weed
Management Plan (BLM PDO 2015), which would be utilized on site during construction and
through the life of the lease.
D.
Lessee must obtain a Maricopa County dust control permit prior to construction.
E.
Any cultural and/or paleontological resources (historic or prehistoric site or object) discovered
by the lessee or any person working on the lessee’s behalf, on public or federal land shall be
immediately reported to the AO. The lessee shall suspend all operations in the immediate area
of such discovery until written authorization to proceed is issued by the AO. An evaluation of
the discovery will be made the AO to determine the appropriate actions to prevent the loss of
significant cultural or scientific values. The lessee will be responsible for the cost of the
evaluation and any decision as to the proper mitigation measures will be made by the AO after
consulting with the lessee.
F.
If any changes are proposed for improvements or developments (ground disturbance) that may
impact cultural resources, consultation needs to be initiated with the BLM Hassayampa Field
Manager. The Hassayampa Field Office Archaeologist would assist the manager in evaluating
the effect of the proposal and recommend appropriate measures to reduce or minimize the
impacts, under Section 106 of the National Historic Preservation Act (NHPA).
G.
The BLM, with possible assistance from the Arizona Site Steward Program, may monitor the
condition of all known cultural sites. If patrols of the known sites indicate that the visitors are
negatively impacting the sites, consultation with the BLM Hassayampa Field Manager and the
archaeologist would be required to address the impacts and develop alternative methods for
deterring such impacts.
H.
Construction and development of the park on BLM administered public land will avoid the
“avoidance area” identified in Exhibit D. This area will be flagged or marked on the ground
before construction begins. All construction workers will be required to stay within the
designated work zones and keep vehicles within marked boundaries. Construction personnel
will also be trained to recognize these markers and understand the associated
equipment‑movement restrictions. Any deviation from this restriction requires prior written

approval from the BLM Authorized Officer (AO).
I.
If human remains are encountered during ground-disturbing activities, all work must
immediately cease within 30 meters (100 feet) of the discovery, and the area must be secured.
The Arizona State Museum, lead agency, SHPO, and appropriate Tribes must be notified of the
discovery. All discoveries will be treated in accordance with NAGPRA (Public Law 101-601;
25 U.S.C. 3001-3013) or Arizona Revised Statutes (A.R.S. § 41-844 and A.R.S. § 41-865), as
appropriate, and work must not resume in this area without authorization from ASM and the
lead agency.
J.
Migratory Bird Stipulations
1. Prior to project initiation, surveys shall be conducted by a qualified wildlife
biologist for the following species:
•
Bendire’s thrasher
•
Gilded flicker
•
Western burrowing owl
2. It is strongly recommended that any activities requiring vegetation removal occur
outside the nesting season (March 1 – August 31) when feasible.
3. If western burrowing owls are detected and the proposed action will impact the
species, the owls shall be relocated by a qualified entity. BLM can facilitate contact
with an organization specializing in burrowing owl relocation.
4. If either Bendire’s thrasher or gilded flicker is detected, a 100‑foot protection buffer
shall be implemented around active nests during the nesting season (March 1 –
August 31).
K.
During construction and operations of the park facilities, “Guidelines for Handling Sonoran
Desert Tortoises Encountered on Development Projects” (Arizona Game and Fish Department
2014) would be followed. (attached)
L.
The following measures from the Recommended Standard Mitigation Measures for Projects in
Sonoran Desert Tortoise Habitat (Arizona Interagency Desert Tortoise Team 2008) would also
be implemented to minimize potential impacts to BLM sensitive species:
1. To the extent possible, construction activities would be scheduled when tortoises are
inactive (typically November 1 to March 1).
2. A desert tortoise protection education program would be presented to all employees,
inspectors, supervisors, contractors, and subcontractors who carry out proposed
construction activities at the project site.
3. Areas of any future proposed new construction or disturbance would be flagged or
marked on the ground prior to construction. All construction workers would strictly
limit their activities and vehicles to areas that have been marked. Construction

personnel would be trained to recognize markers and understand the equipment
movement restrictions involved.
4. Always inspect the work area and beneath all vehicles and equipment prior to starting
and moving equipment to ensure there are no wildlife species in harm’s way, and limit
vehicle use to existing routes to the extent possible. Project-related vehicles should not
exceed 25 mph on unpaved roads within desert tortoise habitat.
5. Project features that might trap or entangle desert tortoises, such as open trenches, pits,
open pipes, etc., would be covered or modified to prevent entrapment and backfilled as
soon as possible.
6. If desert tortoises are encountered during implementation, activities should be modified
to avoid injuring or harming it. If the activities cannot be modified, the tortoise will be
moved according to the Arizona Game and Fish Department’s Guidelines for Handling
Sonoran Desert Tortoises Encountered on Development Projects (AGFD 2014). Take,
possession or harassment of a desert tortoise is prohibited by State law, unless
specifically authorized by AZGFD.
7. Any amendment to the POD that includes additional surface disturbance
would have to be analyzed by the BLM prior to implementation.
M.
The lessee shall comply with all applicable Federal, State and local laws and regulations,
existing or hereafter enacted or promulgated, with regard to any hazardous material, as defined
in this paragraph, that will be used, produced, transported or stored on or within the lease or any
of the lease facilities, or used in the construction, operation, maintenance or termination of the
lease or any of its facilities. “Hazardous material” means any substance, pollutant or
contaminant that is listed as hazardous under CERCLA of 1980, as amended, 42 U.S.C. 9601 et
seq., and its regulations. The definition of hazardous substances under CERCLA includes any
“hazardous waste” as defined in the RCRA of 1976, as amended, 42 U.S.C. 2011 et seq. The
term does not include petroleum, including crude oil or any fraction thereof that is not otherwise
specifically listed or designated as a hazardous substance under CERCLA section 101(14),
U.S.C. 9601 (14), nor does the term include natural gas.
N.
During the period of this lease, the United States, acting through the BLM, shall have the right
to inspect the land covered by the lease at any time, without advance notice. During such
inspections, officials of the BLM may be accompanied by other appropriate federal, state or
local officials.
O.
The lessee or its successor in interest shall comply with and shall not violate any of the terms or
provisions of Title VI of the Civil Rights Act of 1964 (78 Stat. 241) and requirements of the
regulations, as modified or amended, of the Secretary of the Interior issued pursuant thereto (43
