Approved by: Patrick Johnson, City Manager Agenda Location: Consent Calendar SUBJECT: ALL-WAY STOP ON GRAPEVINE ROAD AND HILL DRIVE RECOMMENDATION: Adopt City Council Resolution No. 2022- , establishing an all-way stop at the intersection of Grapevine Road and Hill Drive.
CORRELATION TO CITY COUNCIL GOALS: Traffic: Continue to improve flow of traffic for all forms of travel, reduce congestion, and improve our roads and sidewalks.
PRIOR ACTION: On May 10, 1982, adopted City Council Resolution No. 82-80, designating the intersection of Hill Drive and Grapevine Road as a stop intersection (Vote: 5-0).
PRIOR TRAFFIC COMMISSION ACTION: On September 7, 2022, recommended establishing an all-way stop at the intersection of Grapevine Road and Hill Drive (Vote: 7-0).
STATEMENT ON THE SUBJECT: The City received a request to evaluate the intersection of Grapevine Road and Hill Drive for an all-way stop for traffic calming purposes on Grapevine Road. Staff conducted an evaluation of the intersection using criteria such as traffic volumes, pedestrians, accident history, and other conditions (see Exhibit 2 for evaluation). Staff determined that the intersection of Grapevine Road and Hill Drive does not meet the quantitative criteria for an all-way stop.
Following the staff evaluation, in accordance with the City's Traffic Calming Program, Residents in the area submitted a petition to install an all-way stop at the intersection as a traffic calming measure. The petition (Exhibit 3) and petition verification map (Exhibit 4) indicate that a majority of nearby residents are in support of the all-way stop.
In March 2021, staff collected data that showed the prevailing speeds on Grapevine Road between Grapevine Lane and Hill Drive to be around 35 miles per hour. The speed study is attached as Exhibit 5.
There have also been six reported accidents on Grapevine Road between Moon Road and Jonathan Street in the past five years.
The City Traffic Engineer has determined that an all-way stop is the most feasible solution to manage speeding along Grapevine Road. Exhibit 6 is a memorandum from the City Traffic Engineer documenting this determination.
ACTION: Approved above recommendation, adopted City Council Resolution No. 2022-148.
Vote: 4-0 (Green absent)

Interoffice Memorandum-
Date: August 22, 2022
To: Greg Mayer, City Engineer
From: Sam Hasenin, Principal Engineer
Subject: All-Way Stop on Grapevine Road and Hill Drive Residents submitted a petition to install an all-way stop at the intersection of Grapevine Road and Hill Drive as a traffic calming measure in accordance with the City's Traffic Calming Program. Staff conducted an evaluation of the intersection using criteria such as traffic volumes, pedestrians, accident history, and other conditions. Staff determined that the intersection of Grapevine Road and Hill Drive does not meet the quantitative criteria for an all-way stop.
I evaluated the street segment and I found that based on roadway characteristics, vehicle speeds and accident history, in my engineering judgment and as provided in the City's Traffic Calming Program, an all-way stop at the intersection of Grapevine Road and Hill Drive is the most feasible and effective measure to reduce vehicle speeds on Grapevine Road.
