Report to the Board of Supervisors
Prepared by the Maricopa County Planning and Development Department
Board Hearing Date:
March 13, 2024
Case #/Title:
S2021037 – Riverwalk
Supervisor District:
4
Applicant/Owner:
Joe Cable, Bowman / Chris Brown
Request:
Final Plat for 89 residential lots and eight tracts in the R1-6 RUPD
zoning district
Site Location:
NEC of 99th Avenue and Olive Avenue in the Peoria area
Site Size:
Approximately 15 acres
County Island Status:
Yes (City of Peoria)
Additional
Comments:
Staff considers this final plat in substantial conformance with the
approved preliminary plat for Riverwalk (S2021007). This final plat
meets all applicable subdivision regulations and zoning regulations
outlined in the R1-6 RUPD zoning case (Z2021003) approved by the
Board on July 14, 2021. The approved zoning case conditioned that
the developer conduct a Cultural Resource Survey with the state
historic preservation office before the approval of a final plat which
the developer completed. The result of the survey was that there
were no significant cultural artifacts on site (see attached). Another
condition of the approved zoning case was that a land subsidence
report be completed before the approval of the final plat, which the
developer has completed. The report concluded that the site is not
located in an area of land subsidence (see attached). A final
condition of the approved zoning case was that a ‘will serve’ letter
must be obtained from the local fire protection service, which is
attached.
The applicant has routed a copy of the final plat to all utility and
service providers and all municipalities within three miles of the
site. Recording fees will be furnished at the time of plat recordation.

INTRODUCTION
Residential Pursuits Investments, LLC (“RPI”) is requesting final plat to allow construction
of a high quality 89-lot age restricted subdivision on a 15.31 gross acre site located at
north and east of 99th Avenue and Olive Avenue (the “Property”). The Property is located
in unincorporated area of Maricopa County (the “County”), lies in the southeast quarter of
Section 29, Township 3 North, Range 1 East, and identified by the three main Assessor’s
Parcel Numbers 142-62-694, 142-62-695 and 142-62-884. It is surrounded by New River
on the east, and single family residential to the west, New River and Olive Avenue to the
south, and Brook Hollow Apartments and Sunwood Apartments to the north. The property
is currently vacant land consisting of three main parcels. The northernmost parcel was
previously platted as Riverwalk Condominiums but never constructed. The southern two
parcels are vacant.
II.
PURPOSE OF REQUEST
RPI intends to transform this vacant land into a high-quality age restricted community
called Riverwalk (the “Property”), consisting of 89 detached residential lots at a density
of approximately 7.18 DU/acre with open space featuring passive and active amenities.
The local onsite streets will be private, and will be maintained by the property owner’s
association. The Property would add variety to the lot sizes available in the area and
increase the diversity of home ownership opportunities that is consistent with the west
valley’s growth. The current land use designation is Retirement Community, and the
current zoning is R1-6 RUPD. RPI is requesting final plat approval consistent with the
approved R1-6 RUPD zoning (2021003) and approved preliminary plat (S2021007).
Table A below summarizes the Property Data.

DESCRIPTION OF PROPOSAL
Riverwalk is a proposed age-restricted community consisting of 89 single-family detached
homes. The proposed density is approximately 7.18 DU/acre based on the gross area.
This request is for a final plat to develop the property based on the proposed R1-6 RUPD
standards. The design of the community is consistent with the homeowner desires for less
maintenance of yards all while having access to a shared community amenities and
sizeable open space areas that are maintained by the homeowner’s association.
The minimum lot dimensions will be 45 feet wide by 80 feet deep, with a minimum lot size
of 3,600 square feet. The R1-6 RUPD zoning district’s development standard for minimum
area per dwelling unit is 6,000 square feet. With 89 lots on 15.31 acres, the Property will
provide at least 6,000 square feet per dwelling unit when considering both the area of the
lot and the Property open spaces. The Property will include approximately 4.05 acres of
open space, which is more than 26% of the gross area. The central open space is
anticipated to be 1.36 acres of the 4.05 acres of total open space and will have pedestrian
paths that link to the open space amenities. The RUPD Development Standards are
shown below in Table B.
The Primary access to the site will be from 99th Avenue. This entry will include an elegant
entry monument as well as gated entry, bordered by lushly landscaped open space areas,
with a variety of trees, shrubs, and areas of turf. The onsite local streets in this gated
community will be privately owned and maintained by the property owner’s association.
The centralized amenity area will feature a pool with lounge seating, outdoor barbecue
area, and a restroom building with shaded seating and outdoors showers. Adjacent to the
amenity is a community green space providing residents with a usable turf area. Much of
the community is surrounded by broad landscape areas that provide a buffer from the
perimeter streets outside of the community and serve as retention for the development.
All internal drives will be private streets and will include four-foot sidewalks on both sides
to establish pedestrian connectivity throughout the neighborhood, and to ensure
convenient access to the amenity and open space areas.
New landscaping along 99th and Olive Avenues consists of staggered rows of street trees
to buffer the community and to provide pedestrian shade for the sidewalks. Planting areas
inside the community will use the same material plus additional accented areas of colorful
plants. A large, turfed area will be the main community gathering area central to the site
and will also act as the central retention area for the development. Another retention area
will be located in the northeast corner of the Property which will be landscaped with turf.

RELATIONSHIP TO SURROUNDING AREA
The Property is bordered by 99th and Olive Avenues to the west and south, respectively.
It is north and west of the City of Peoria, east and south of the unincorporated community
of Sun City. It is located 1 mile west of Loop 101 Freeway, 2 miles north of the Glendale
Municipal Airport and 2 miles south U.S. Route 60.
The property located at the east boundary is the New River Wash, owned and maintained
by Flood Control District of Maricopa County. Located to the north of the property is the
Sunwood Apartments and Brook Hollow Condominium, zoned R-4. The Sun City Unit 8
lies to the West beyond 99th Avenue, zoned R1-6. Both 99th and Olive Avenues are fully
improved with two lanes in each direction and dedicated left turn lanes, with curb and
gutter. Sidewalk has been constructed along Olive Avenue, but not along 99th Ave. The
dedicated Right-of-Way (ROW) for Olive Ave meets the ultimate street section
requirement of 65’ half street, 130’ full street width. There is 55’ of Right-of-Way dedicated
for the east half width of 99th Ave, 110’ total for the total width. MCDOT granted approval
to keep the ROW at 55’ rather than expanding it to 65’ for principal urban arterial.

LOCATION AND ACCESSIBILITY
The existing arterial roadways that will serve the Property are 99th Avenue and Olive
Avenue. 99th Avenue and Olive Avenue are designated as Urban Principal Arterial per
Maricopa County Department of Transportation’s Major Streets and Routes Plan (2011).
99th Avenue has a north-south alignment and provides two lanes in each direction
separated by a raised median. There are a curb and gutter on both sides of 99th Avenue,
but no bicycle or pedestrian facilities.
Olive Avenue has an east-west alignment and provides two lanes in each direction. There
is a painted median throughout the Property limits and no bicycle lanes. Olive Avenue has
curb and gutter and sidewalks in both directions.
The Loop 101 freeway, US State Highway 60 are the existing regional transportation that
serve the Property. Loop 101 is located 1 mile east of the Property with full interchanges
with access to U.S. Route 60 or 2 miles from the Property.
VI.
CIRCULATION SYSTEM
The traffic circulation is outlined in the Riverwalk Residential Development Traffic Impact
Analysis (“TIA”) prepared November 2020, which was submitted with the rezone and
preliminary plat applications. The site entrance will be on 99th Avenue with a gated entry
into the community. It will be constructed with 20’ wide entry and exit lanes separated by
a landscaped median. The site access driveway is recommended to provide a stop sign
on the new westbound approach from the site to 99th Avenue. The internal streets are
considered private roads to be maintained by the homeowner’s association. A secondary
emergency access from Olive Avenue will be located at the south end and constructed of
4-inch compacted decomposed granite to meet the Sun City Fire District design standards
and the adopted fire code.
The intersections at Olive Avenue/99th Avenue and Caron Drive/99th Avenue were
evaluated for the TIA. The intersection at Olive Avenue/99th Avenue is controlled by a
traffic signal. The signal provides a protected-permitted phase for the eastbound left-turn
onto 99th Avenue. The proposed Property, the intersection will operate an acceptable level
of service during AM/PM peak hours for the years studied, 2021 and 2025. The Property
is anticipated to generate a total of 953 weekday daily trips (entering and exiting) with 75
during the AM peak hour and 100 during the PM peak hour. No improvements are
recommended at the intersection of 99th Avenue and Olive Avenue as the intersection will
operate at an adequate LOS (LOS D or better). A northbound right-turn lane with a
minimum storage length of 160 feet is recommended at 99th Avenue and Caron Drive. The
proposed site access driveway is recommended to provide a STOP sign on the new
westbound approach for traffic exiting the site.
VII.
PROJECT PHASING AND DEVELOPMENT SCHEDULE
This Property will be developed as one single phase. Construction will begin shortly after
final plat and engineering plan approval. Construction will take 6 to 8 months.

Re:
Certificate of Assured Water Supply
Riverwalk
DWR File No. 31-700291.0001
Dear Ms. Hauver:
The Arizona Department of Water Resources (Department) has determined that the criteria for an Assured
Water Supply pursuant to A.R.S. § 45-576 and A.A.C. R12-15-701 et seq. have been met, and therefore the
Director has decided to issue Certificate of Assured Water Supply No. 31-700291.0001, attached.
EPCOR - Sun City will provide water to the subdivision. The source of supply will be groundwater. The
annual estimated water demand of the subdivision is 35.84 acre-feet per year for 91 lots, and the
groundwater allowance for the subdivision for the 100-year period is 143.36 acre-feet. Pursuant to A.R.S.
§ 45-578(F), the total projected average annual replenishment obligation at build-out for each plat under
the Certificate is 34.41 acre-feet per year.
The Department suggests you record your Certificate of Assured Water Supply in the appropriate county
recorder’s office. This will provide you with a permanent public record of the Certificate. This
determination is applicable only to the persons or entities specified on the Certificate and for the plat
reviewed by the Department, including non-material plat changes pursuant to A.A.C. R12-15-708.
Pursuant to A.R.S. § 41-1092.03, the Director’s determination and decision to issue the Certificate is an
appealable agency action. You are entitled to appeal this action. If you wish to appeal this action, you

5. DESCRIPTION OF PROJECT or UNDERTAKING: Arcadia Capital is proposing to develop the Riverwalk
project, a proposed residential development at the northeast corner of North 99th Avenue and West
Olive Avenue in Peoria, Maricopa County, Arizona (Figure 1). The project area is approximately 15 acres
of undeveloped land, and required compliance with City of Peoria rezoning regulations. Arcadia Capital
contracted with SWCA to conduct a cultural resources inventory of the project area to identify cultural
resources that may qualify as historic properties (i.e., cultural properties listed in or eligible for listing
in the Arizona Register of Historic Places [ARHP] or National Register of Historic Places [NRHP]).
6. PROJECT AREA/APE: The project area is a comprised of one 15-acre area of privately owned land.
The maximum dimensions of the project area are approximately 308 m × 271 m.

9. ENVIRONMENTAL CONTEXTS
9a. Landform: Terrace above the New River
9b. Elevation: 1,090 feet above mean sea level
9c. Surrounding Topographic Features: The project area is located approximately 10.4 miles west of
North Mountain and 11.2 miles north of the Estrella Mountains.
9d. Nearest Drainage: The project area is adjacent to west of the New River
9e. Local Geology: The Arizona Geological Survey has identified the surficial geology within
the project area as late and middle Pleistocene surficial deposits composed of poorly to moderately
sorted gravel and sand (Arizona Geological Survey 2013).
9f. Vegetation: The natural vegetation in the project area has been mostly cleared except for the
occasional grasses and shrubs. Prior to this development, the project area would have contained
vegetation characteristic of the Lower Colorado River Subdivision of the Sonoran Desertscrub biotic
community as described by Brown (1994).
9g. Soils/Deposition: Mapped soil units in the project area include Laveen loam, Rillito loam, Vint fine
sandy loam, which range from limy fan to sandy wash to sandy bottom (Natural Resources
Conservation Service 2022).
9h. Buried Deposits: Not likely
9i. Justification: The project area has no surface evidence that would indicate the likelihood for
subsurface cultural deposits.
10. BUILT ENVIRONMENT: The project area is surrounded by paved roads and sidewalks, an apartment
residence to the north with a trail adjacent to the south. In the northeast corner of the project area
there is a small structure likely housing utility access.

12f. Historical Maps: The General Land Office (GLO) map for Township 3 North, Range 1 East, filed in
1868, does not depict any resources within the project area or the 1-mile research buffer.
The 1957 U.S. Geological Survey El Mirage, Arizona, 7.5-minute topographic quadrangle depicts a large
reservoir in the approximate location of the project area. In the 1-mile research buffer there are 99th
Avenue, Peoria Avenue, 107th Avenue, Olive Avenue, Northern Avenue, two improved road, two
unimproved roads, two canals, 22 buildings/structures, two wells, and seven reservoirs.
12g. Land-Managing Agency Files: Not Applicable
12h. Tribal Cultural Resources Files: Not Applicable
12i. Local Government Websites: Not applicable
12j. Other: Historical aerial imagery from 1949 shows two-track roads within the project area. The
surrounding area appears farmland. Imagery from 1959 confirms the reservoir depicted on the 1957
U.S. Geological Survey El Mirage, Arizona, 7.5-minute topographic quadrangle exists within the project
area (Maricopa County 2022).
13. BACKGROUND RESEARCH RESULTS
13a. Previous Projects within the Project Area
Twenty-four archaeological surveys ranging from 2020 to 1985 have been conducted within 1-mile of
the project area, five of which intersects the project area. No reference information is available for the

18. COMMENTS: A Class III cultural resources survey for the Riverwalk Project resulted in no
discoveries of archaeological materials or historic-era buildings, structures, objects, or districts in the
project area. The 1957 U.S. Geological Survey El Mirage, Arizona, 7.5-minute topographic quadrangle
depicts a large reservoir in the approximate location of the project area; however, the project area is
not currently constructed to be used as a reservoir. Therefore, this project will not directly affect
properties listed in or eligible for listing in the ARHP or the NRHP.

Earth Fissure and Land Subsidence Commentary

Chris,
As requested, this addendum has been prepared to discuss ground subsidence and earth fissures
at the above-mentioned project.
Ground Subsidence and Earth Fissure Commentary
The project site is situated within the Basin and Range Province of Arizona in Glendale, Arizona.
The area has been affected by a period of regional extension that resulted in a series of normal
fault-block mountains and basins. The up-thrown side of the normal fault forms a mountain that
rises steeply and the down-dropped side forms low valleys. After tectonic activity ceased, a series
of alluvial fans and pediments formed along the margins of the mountain ranges. Continued
erosion of the mountain ranges buries these normal faults, as well as other discontinuities of the
rock mass, under hundreds of feet of sediments.
Earth fissures in the area are more than likely clustered above or near these normal faults or
buried discontinuities as differential compaction above steeply sloped bedrock surfaces results in
both vertical and horizontal strain in the basin sediments (see the illustration on the following page
for the differing mechanisms of earth fissuring).
Land Subsidence - Land subsidence is a reduction in surface elevation resulting from the loss of
subsurface support at rates that are significant to man-made structures. Land subsidence is
caused by various natural and anthropogenic activities. The most common types of land
subsidence can be attributed to land development and resource extraction (i.e., underground
mining, underground fluid withdrawal, etc.). In southern Arizona subsidence features are closely
linked to long-term withdrawal of groundwater. Both fluid pressures and the aquifer sediments
support the weight of the overburden material above an aquifer. As groundwater is extracted, the
buoyant forces decline, and the drained unconsolidated aquifer soils lose the ability to support
overlying sediments. As a result, a permanent loss of pore volume will occur, and the aquifer will
consolidate as it adjusts to the new stresses. This aquifer consolidation translates at the surface
as land subsidence.

Figure 1: Illustration showing the differing mechanisms of earth fissuring.
Figure 1 referenced from: South-Central Arizona, Earth fissures and subsidence complicate
development of desert water resources, Michael C. Carpenter, U.S. Geological Survey, Tucson,
Arizona.
Earth Fissures - Earth fissures are a localized manifestation of land subsidence that appears as
surficial tensile cracks in unconsolidated soils. Typically, subsidence is not uniform throughout
an area because of subsurface geology, ground water conditions, and ground water pumping
rates. It is when this differential subsidence occurs that fissures arise. Earth fissures develop
from narrow cracks or lines of small shallow depressions into large gaping features most
commonly from surface water runoff.
Please note, earth fissures can only be identified if they are visible at the surface. Very young
fissures typically lack the tell-tale signs (i.e., vegetation, width, continuity, etc.) that allow young,
mature, and old earth fissures to be identified. If local and regional groundwater withdrawal
exceeds groundwater recharge, and land subsidence continues, then there is a risk that earth
fissures may form at locations where no earth fissures currently exist.
The nearest earth fissure study area is known as the Luke Study Area (approximately 2.8 miles
to the west). An Earth Fissure Map of the northern portion of the Luke Study Area is shown below.
The map is referenced from Google Maps and the UA Science, Arizona Geological Survey,

earth fissure(shown in green) 3.0 miles to the west of the site location
In conclusion, during the site investigation performed on November 11, 2020, no evidence of
localized subsidence, such as earth fissures, were detected at the project site. Because no visual
evidence of land subsidence and earth fissures were observed at the site, and because the site
is not located within an active study area, the site is not considered by this firm to be an active
earth fissure site. During construction, if evidence of land subsidence or earth fissures is
encountered, this firm must be contacted to perform a further investigation.
This concludes all items to be addressed by this addendum, which must be attached to the initial
report and made a part thereof. Should any questions arise concerning the content of this
addendum, please feel free to contact this office as soon as possible.
