INTRODUCTION AND SUMMARY 
Introduction 
Rick Engineering Company (RICK) is commissioned to perform a comprehensive traffic impact study to 
evaluate the impact of a proposed multifamily residential development along east side of 91st Avenue 
approximately 630 feet south of the Glendale Avenue and 91st Avenue intersection (parcel # APN 102-
02-001A). The proposed development would consist of no more than 392 multifamily dwelling units.  
 
The study area and scope were determined based on maximum peak hour trip generations from the 
proposed development (100+ trips) and Maricopa County Department of Transportation (MCDOT) 
Traffic Impact Study guidelines (Category I) per several conversations with the City of Glendale (COG) 
and the directions received.  
  
Executive Summary 
As previously mentioned, the proposed development would consist of residential development. The 
following land use codes from the Institute of Transportation Engineers (ITE) was utilized:   
 
❖ Mid-rise multifamily dwelling (392 units) – ITE Code 221 
 
It is proposed that the development will be constructed in a single phase and is expected to be opened 
in the year of 2022. It is estimated that a total of 2,135 trips will be generated from the proposed 
development on a typical weekday. Among these, 131 trips (34-inbound/97-outbound) will be 
generated in the AM peak and 164 trips (100-inbound/64-outbound) will be generated in the PM peak.  
 
The existing year 2021 turning movement counts were obtained on Thursday August 5, 2021. City of 
Glendale database shows a seasonal adjustment factor of 1.099 for data collected in August on a 
Thursday. Therefore, the existing volumes were scaled up with a factor of 1.10 to get 2021 adjusted 
volume. Per a discussion with City of Glendale engineers, a growth factor of 3% was used upon the 2021 
adjusted volumes to calculate the background volumes for the buildout year, 2022 and horizon year, 
2027. 
 
The site traffic was distributed and assigned onto the study area transportation network based on the 
existing traffic turning movement counts, surrounding land use and knowledge of local traffic patterns, 
and directions from the partnering agencies. The site generated traffic was added to the estimated 2022 
and 2027 background traffic, and 2022 and 2027 combined traffic were estimated.  
 
The LOS analyses show that the transportation network accommodates the site traffic without any 
major delay at any major approaches of the network. There are delays in the northbound and 
southbound approach of Glendale at 89th Avenue intersection. But these are minor approaches, and it is 
not uncommon for minor approaches at major intersection to have a delay next to a major arterial such 
as Glendale Avenue. It is noted that the overall LOS is D or better for all scenarios at all intersections.  
 
No queue spill over at any intersections is anticipated. The following improvements are identified and 
recommended: 
❖ Northbound right turn deceleration lane at Driveway A i.e., off to 91st Avenue is constructed 
with at least 75 feet storage and 85 feet taper.

❖ On-site pedestrian crossings and sidewalks in compliance with the Americans with Disabilities 
Act (ADA) ensuring full accessibility to all types of pedestrians 
❖ Appropriate STOP signs at the site driveways to remind the vehicles leaving the property that 
the driveway vehicles are to yield the right-of-way to the through vehicles  
❖ Proper turn-around area at the gates to complete safe turn-around by the vehicles not entering 
the site but visiting the gate by mistake. 
❖ No objects higher than 3 feet is installed in the American Association of State Highway and 
Transportation Officials (AASHTO) recommended sight visibility triangle at the access points.
