Traffic Impact Analysis –September 2024 
EXECUTIVE SUMMARY 
INTRODUCTION 
VAI Resort is located on an approximately 60-acre parcel in the southwest corner of 95th Avenue and Cardinals 
Way near State Farm Stadium in Glendale, Arizona. The development will consist of hotel rooms, 
conference/meeting space, a semi-public swimming pool, an island with bar, restaurants, retail, a concert 
venue, and a Mattel Adventure Park. This traffic impact analysis was prepared in accordance with the 
requirements of the City of Glendale. The project generates more than 1,000 peak hour trips. The opening year 
for the proposed development is considered as 2025 for this analysis. The analysis study years include 
existing and horizon years 2025, 2035 and 2045 (20 years after opening). The weekday PM peak hour and 
Saturday peak hour (late afternoon) were studied since they correspond to both the peak operation of the 
proposed development and the adjacent roadway peaks. 
TRIP GENERATION 
Full build-out of the proposed development is anticipated to generate 24,507 weekday daily trips 
(entering/exiting) with 2,552 trips (entering/exiting) during the Weekday PM peak hour and 3,069 trips 
(entering/exiting) during the Saturday Peak Hour. Internal trip reductions were applied to specific uses within 
the development. 
EXISTING LEVEL-OF-SERVICE 
The movements and approaches at the study intersections are currently operating at level of service “E” or 
better during the weekday PM peak hour and Saturday peak hour with existing conditions and signal timings. 
FUTURE LEVEL-OF-SERVICE 
The movements and approaches at the study intersections will operate at level-of-service ‘E’ and above during 
the weekday PM peak hour and Saturday peak hour of the horizon years with the exception of the Loop 
101/Cardinals Way, 95th Avenue/Cardinals Way, 91st Avenue/Cardinals Way, 91st Avenue/Camelback Road, 
95th Avenue/Camelback Road and 99th Avenue/Camelback Road intersections.  
RECOMMENDED MITIGATION MEASURES 
It is recommended to review and optimize existing corridor traffic signal cycle lengths and traffic signal phasing. 
This includes developing various plans for the weekday, weekend and event time periods. Cardinals Way and 
Camelback Road are currently programmed with coordination and 145 second cycle lengths during the PM 
peak hour and 120 second cycle lengths on the weekend. The level-of-service at the Loop 101/Cardinals Way 
and 95th Avenue/Cardinals Way intersections could be improved by reevaluating signal timing with future 
conditions.  
 
A future connection to the Loop 101 from the west side of the development is under consideration. This 
analysis does not account for a potential Loop 101 connection, and therefore makes conservative 
recommendations with the assumption that all traffic will enter/exit the site from 95th Avenue. 
 
Camelback Road 
The daily traffic volume on Camelback Road is projected to reach 47,000 vpd in horizon year 2045 with 
background traffic only and will approach capacity as a four and five-lane roadway warranting a six-lane 
section. To achieve acceptable levels of service at the study intersections on Camelback Road, three through 
lanes in each direction are warranted in the horizon year.

Traffic Impact Analysis –September 2024 
 
The 91st Avenue/Cardinals Way, 91st Avenue/Camelback Road, 95th Avenue/Camelback Road, and 99th 
Avenue/Camelback Road intersections will experience delay with the growth of traffic volumes. The site traffic 
will have an additional impact at the 95th Avenue/Camelback Road and 91st Avenue/Cardinals Way 
intersections, since they are entryways to the site driveways on 95th Avenue and the parking garage on 
Montebello Avenue. In addition to three through lanes in each direction on Camelback Road, the following 
additional turn lanes are recommended: 
 
91st Avenue and Cardinals Way 
 Northbound dual left-turn 
 Eastbound right-turn 
 Westbound dual left-turn 
 Maintain existing turn lanes 
 
91st Avenue and Camelback Road 
 Northbound dual left-turn 
 Northbound right-turn 
 Westbound right-turn 
 Maintain existing turn lanes 
 
95th Avenue and Camelback Road 
 Dual southbound left-turn  
 Dual eastbound left-turn 
 Maintain existing turn lanes including dual southbound right-turn lanes provided with existing conditions 
 
99th Avenue and Camelback Road 
 Northbound right-turn 
 Dual westbound left-turn 
 Dual southbound left-turn  
 Southbound right-turn lane 
 Maintain existing turn lanes 
 
With the above improvements, the movements and approaches at the study intersections are anticipated to 
operate at level of service “E” or better. 
 
Site Access 
Four main driveways are proposed on 95th Avenue. There is also a service-only driveway and employee 
driveway (not included in the analysis). The most northern driveway (Site Access A) is proposed as left-in, 
right-in and right-out and provides access to the hotels and a loop road that goes around the resort. Site 
Access B provides full access to a valet area. The two south driveways on 95th Avenue provide direct access 
to the Mattel Adventure Park while providing access to the loop road around the resort. The driveways near the 
Mattel Adventure Park are designed with a right-out exit only (Site Access C1) driveway and a right-in, left-in 
enter only (Site Access C2) driveway. Site Access D is a driveway to a new parking garage that is proposed on 
Montebello Avenue west of 91st Avenue. Site Access E (right-in and right-out) is a proposed driveway on 91st 
Avenue that will provide additional access to the new garage. There is also a shared ride drop-off/pick-up 
staging area with two driveways provided on Montebello Road east of 95th Avenue. The three existing Black 
Lot driveways on Montebello Road will remain open.

Traffic Impact Analysis –September 2024 
 
The site driveways will be stop sign controlled. Dedicated left-turn lanes will be provided on 95th Avenue at the 
driveways that allow left turns into the site, which include Site Access A, Site Access B and Site Access C2.  
 
Right-turn deceleration lanes are provided at the site driveways on 95th Avenue. 
IMPROVEMENTS BY DEVELOPMENT 
 Install new median and revise striping on 91st Avenue adjacent to the property 
 Revise striping on Montebello Avenue between 91st Avenue and 85th Avenue 
 Restripe southbound 95th Avenue approach at Cardinals Way to provide new right-turn lane 
 Provide one new marked crosswalk on 95th Avenue and Montebello Avenue 
 Install new wayfinding signage on all approaches to the site 
EVENT TRAFFIC MANAGEMENT 
VAI traffic management, circulation and pedestrian accommodations during the Arizona Cardinals gameday, 
and other major events at the adjacent football stadium, will be coordinated with the City staff and law 
enforcement. Additionally, a separate agreement will be entered into between the VAI ownership and the City 
to develop event traffic management plans during special events at the VAI resort and concert venue.
