SARIVAL CARIOCA
SARTIVAL AVENUE/PEORIA AVENUE
REVISED TRAFFIC IMPACT ANALYSIS

Executive Summary

The purpose of this traffic study is to evaluate the current and future transportation system
within the project study area surrounding the site without and with the proposed Sarival
Carioca project.

Existing Traffic Data
The existing intersection of Sarival Avenue/Peoria Avenue currently operates at an
adequate level of service (LOS) during the weekday AM and PM peak hours.

Future Traffic Data Without the Project

The existing intersection of Sarival Avenue/Peoria Avenue is anticipated to continue
operating at an adequate LOS in 2023 and 2026 during the weekday AM and PM peak
hours without traffic from the project.

Future Traffic Data With Project

The shared eastbound through/right turn movement at the intersection of Sarival
Avenue/Peoria Avenue is expected to operate at an inadequate LOS in 2026 with traffic
from the project during the weekday AM peak hour. The delay is due to the limited capacity
provided at the intersection and ALL-WAY STOP control becoming inefficient with the
growing traffic volumes in the area, as each vehicle is required to stop and proceed through
the intersection one at a time.

The remaining study intersections are anticipated to operate at an acceptable LOS during
the weekday AM and PM peak hours in 2023 and 2026 without and with traffic from the
project.

Turn Lane Analysis
An eastbound right turn lane is proposed at the intersection of West Access/Peoria Avenue.

The existing two-way center left turn lane on Sarival Avenue is expected to serve
southbound left turning movements at North Access/Sarival Avenue and South
Access/Sarival Avenue. Northbound right turn lanes are also proposed at North Access and
South Access and required at Sarival Avenue/Peoria Avenue per City of Glendale
direction.

The proposed eastbound right turn lane at West Access is expected to serve a queue of 25
feet of storage.

The proposed northbound right turn lane at North Access and South Access are expected
to be free flow movements with minimal, if any, queue length.

The required northbound right turn lane at the intersection of Sarival Avenue/Peoria
Avenue is anticipated to need a queue of 25 feet of storage.

No queue overlap is anticipated to occur between the project driveways and adjacent
intersections.

Crash Analysis

There were seven (7) reported crashes (1 with injury) within the three-year study period at
the intersection of Sarival Avenue/Peoria Avenue. The most common crash type was angle
(57%) and single vehicle (29%) crashes. These types of crashes may be due to the
intersection being in a undeveloped, relatively low volume traffic area, with vehicles not
completing a full stop at the intersection prior to entering the intersection.

Traffic Signal Warrant Analysis
The intersection of Sarival Avenue/Peoria Avenue is expected to meet traffic signal
warrants #1 and #2 in 2023 and 2026 with traffic from the project.

Mitigation

The shared eastbound through/right turn movement at the intersection of Sarival
Avenue/Peoria Avenue is expected to operate at an inadequate LOS in 2026 with traffic
from the project during the weekday AM peak hour. The delay is due to the limited capacity
provided at the intersection and ALL-WAY STOP control becoming inefficient with the
growing traffic volumes in the area, as each vehicle is required to stop and proceed through
the intersection one at a time. This intersection is expected to be widened and signalized
once the northwest and southwest corners of Sarival Avenue/Peoria Avenue are developed
by future adjacent projects. Upon the construction of the future developments all
approaches to the intersection of Sarival Avenue/Peoria Avenue are expected to be
provided an exclusive left turn lane, two through lanes, and a dedicated right turn lane.
These improvements are expected to alleviate the delay at the intersection.

Recommendations

The proposed eastbound right turn lane at West Access and northbound right turn lane at
Sarival Avenue/Peoria Avenue, North Access, and South Access should be constructed
with a minimum 160 feet of storage with 100 feet of taper to meet City of Surprise and
City of Glendale minimum requirements.
