INTRODUCTION 
The Bethany 303 light industrial development (“the Development”) is being planned 
for the approximate 8-acre subject site located north of the northwest corner of Loop 
303 & Bethany Home Road in Glendale, Arizona.  The Development is currently being 
planned to include two spec general light industrial buildings totaling +/- 151,700 
square feet.  Per input from ownership, build out and full occupancy of the 
Development is planned to occur by year 2026.  
 
Figure 1: Aerial View & Vicinity depicts the location of the subject site within the 
surroundings.  The site plan is presented in Figure 2: Site Plan.  All figures are provided 
in Appendix A: Figures. 
 
This Traffic Statement (TS) has been prepared to accompany the Planned Area 
Development (PAD) amendment and associated site plan and design review 
application of the site.  The TS has been performed in general accordance with 
scoping input provided by the City of Glendale City Traffic Engineer and 
Transportation Department; locally accepted standards and industry practice.  
  
The purpose of this TS is to estimate the weekday, AM peak hour, and PM peak hour 
trip generation of the Development; discuss the site accessibility for the Development; 
and provide the forecasted site traffic volumes at the site access driveway intersections 
on Bethany Home Road; and provide a traffic signal warrant analysis for the shared 
driveway intersection on Bethany Home Road. 
 
SITE DESCRIPTION 
The Development is planned for the PAD subject site located north of the northwest 
corner of Loop 303 & Bethany Home Road, specifically having APN 501-03-009P.  The 
subject site is currently unimproved fallow agricultural land.  North of the subject site is 
unimproved fallow agricultural land; south of the subject site is unimproved fallow 
agricultural land (planned developments include a QuikTrip); east of the subject site is 
the Loop 303; west of the subject site are existing light industrial buildings.  
PROPOSED LAND USE AND DEVELOPMENT 
The Development is currently being planned to include two spec general light 
industrial buildings totaling +/- 151,700 square feet.  
 
SITE ACCESSIBILITY   
Access to the external roadway network for the subject site will be provided via two 
planned shared access points on Bethany Home Road.  “Access A” is an existing full 
movement driveway shared with the adjacent industrial buildings and the south-
adjacent parcel being planned for a QuikTrip convenience store and fueling center.    
 
“Access B” is a future right-in, right-out access shared with the adjacent parcels.  
Access B is planned approximately 380 feet east of the existing Access A (inside edge

2 
 
to inside edge) and will have a right-turn deceleration lane.  Direct site access interior 
to the shared drive network is depicted in the attached site plan in Figure 2.   
SITE TRAFFIC GENERATION  
Estimates of the traffic volumes that will be generated by the proposed development 
at full build out are determined from transportation planning data within the Institute of 
Transportation Engineers (ITE) Trip Generation Manual, 11th Edition, 2021.  ITE Land 
Use Code (LUC) 110 – General Light Industrial is utilized.    
 
Table 1:  Trip Generation – Bethany 303 Light Industrial Development presents the 
estimated daily and peak hour trips generated by the Development for a typical 
weekday.

On a typical weekday, the Development is estimated to generate 112 trips in the AM 
peak hour, 99 trips in the PM peak hour, and 739 daily trips. 
 
SITE TRAFFIC DISTRIBUTION AND ASSIGNMENT 
The assumed trip distribution percentages of the site’s trips are generally based on the 
type of development (employment-based) and connectivity to the Loop 303 and the 
major arterial roadway corridors adjacent to the site Table 2: Trip Distribution 
Percentages presents the assumed trip distribution percentages for the Development.

The forecasted site traffic for the Development is assigned at the shared accesses on 
Bethany Home Road taking into consideration the functionality and location of each 
access relative to the subject site.   Exhibit A below presents the site traffic volumes on 
Bethany Home Road at Access A and Access B.

Exhibit A – Site Traffic Volumes  
 
TRAFFIC SIGNAL WARRANT ANALYSIS – ACCESS A & BETHANY HOME ROAD 
The Manual on Uniform Traffic Control Devices (MUTCD) was utilized to determine if a 
traffic signal is warranted at the shared access driveway intersection of Access A & 
Bethany Home Road for existing, background (2026), and total traffic (2026) volume 
conditions. 
 
Existing 24-hour turning movement traffic counts were collected at the shared Access A 
& Bethany Home Road intersection by United Civil Group on Tuesday, August 27, 
2024.  The existing traffic data is provided in Appendix B: Traffic Data. 
 
Background (non-site) traffic volumes representing the amount of traffic estimated at 
the intersection without the Development are projected for the opening year 2026.  
The projected background traffic volumes include applying a Compound Annual 
Growth Rate (CAGR) of 5% to the existing traffic volumes on Bethany Home Road at 
the intersection, as well as the inclusion of the projected site trips of the known 
adjacent development projects that will utilize the shared Access A.   
 
Per coordination with the City of Glendale, the adjacent development projects to 
include in the background traffic are: the QuikTrip planned for the northeast corner of 
Access A & Bethany Home Road (site trips acquired from the Levine Investments Traffic 
Impact Study, Civtech, February 2023); and the 303 Commerce Center (Scannell 
Properties) project located north of the Development (site trips acquired from the 
Traffic Impact Study for the 303 Commerce Center, United Civil Group, February 2021).  
The Scannell Properties development includes two industrial buildings, one of which is 
constructed.  However, at this time the constructed building does not appear to have a 
tenant and/or is not fully opened and utilized.  Therefore, all of the projected site trips 
from the TIA will be included in the background as it is assumed to be fully built out by

4 
 
2026.  The traffic volumes for the adjacent developments are provided in Appendix D:  
Site Traffic Volumes of Adjacent Developments. 
 
Exhibit B below presents the existing, background (non-site) 2026, and total (with site) 
2026 traffic volumes at the shared Access A & Bethany Home Road intersection.  
 
 
Exhibit B – Traffic Volumes at shared Access A & Bethany Home Road 
 
There are nine specific signal warrants in the MUTCD, however, not all warrants are 
applicable.  The warrants as part of this analysis include: 
Warrant 1 – Eight-Hour Vehicular Volume 
Warrant 2 – Four-Hour Vehicular Volume 
Warrant 3 – Peak-Hour Vehicular Volume 
 
The intersection has recently been constructed, opened, and utilized by the adjacent 
industrial site.  No crash data is available via the Arizona Department of Transportation 
(ADOT) Arizona Crash Information System (ACIS) due to the recent opening. 
 
The highest hourly volumes utilized in the warrants were determined by applying 
hourly adjustment factors to the peak hour volumes associated with the recent 24-hour 
traffic volume count collected at the shared Access A & Bethany Home Road 
intersection.  The results of the traffic signal warrant analyses are provided in Appendix 
C: Traffic Signal Warrant Analyses.

Traffic Signal Warrant Results 
Access A & Bethany Home Road:   
• Existing Conditions 
 Warrant 1, Warrant 2, and Warrant 3 are not met. 
• Background (non-site) Traffic Conditions, Year 2026 
 Warrant 1, Warrant 2, and Warrant 3 are met. 
• Total (with site) Traffic Conditions, Year 2026 
 Warrant 1, Warrant 2, and Warrant 3 are met. 
 
As shown above, the traffic signal volume warrants are not met at the intersection of 
Access A & Bethany Home Road for the existing conditions.  The traffic signal volume 
warrants are met at the intersection of Access A & Bethany Home Road for the 
background (non-site) 2026, and total (with site) 2026 traffic volume conditions. 
 
SIGHT DISTANCE REQUIREMENTS 
Proper intersection sight distance and sight triangles shall be provided and maintained 
at the site accesses intersections of the proposed development (exterior intersections 
as well as interior shared drive intersections) to give drivers exiting the accesses a clear 
view of oncoming traffic.  The landscape and hardscape within the sight triangles must 
not obstruct the driver’s view of the adjacent travel lanes.  To ensure adequate sight 
distances and sight distance triangles, AASHTO’s A Policy on Geometric Design of 
Highways and Streets, and City of Glendale Standard Details G-447 and G-448 should 
be followed as applicable when designing the access points.   
 
CONCLUSIONS 
The Bethany 303 light industrial development is being planned for the approximate 8-
acre subject site located north of the northwest corner of Loop 303 & Bethany Home 
Road in Glendale, Arizona.  The Development is currently being planned to include 
two spec general light industrial buildings totaling +/- 151,700 square feet.  Per input 
from ownership, build out and full occupancy of the Development is planned to occur 
by year 2026.   
 
Access to the external roadway network for the subject site will be provided via two 
planned shared access points on Bethany Home Road.  “Access A” is an existing full 
movement driveway shared with the adjacent industrial buildings and the south-
adjacent parcel being planned for a QuikTrip convenience store and fueling center.  
“Access B” is a future right-in, right-out access shared with the planned Super Star car 
wash.  Access B is planned approximately 380 feet east of the existing Access A (inside 
edge to inside edge).      
 
On a typical weekday the Development is estimated to generate 112 trips in the AM 
peak hour, 99 trips in the PM peak hour, and 739 daily trips.  Exhibit A above presents 
the forecasted site traffic volumes at Access A and Access B during the AM and PM 
peak hours.

Traffic signal volume warrants are not met at the intersection of Access A & Bethany 
Home Road for the existing conditions.  Traffic signal volume warrants are met at the 
intersection of Access A & Bethany Home Road for the background (non-site) 2026, 
and total (with site) 2026 traffic volume conditions. 
 
This Traffic Statement is based on a variety of assumptions related to the site plan and 
land use of the proposed development.  If a greater density, alternate land use, or site 
accessibility is ultimately proposed, the trip generation calculations and criteria 
evaluation may not remain valid.
