DRIVE/ROMA DRIVE
RECOMMENDATION: Adopt City Council Resolution No. 2023- , establishing an all-way stop at the intersection of Lupine Hills Drive and Portofino Drive/Roma 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: None.
PRIOR TRAFFIC COMMISSION ACTION: On June 7, 2023, recommended establishing an all-way stop at the intersection of Lupine Hills Drive and Portofino Drive/Roma Drive (Vote: 5-0) (Commissioner Matheus absent, one vacancy).
STATEMENT ON THE SUBJECT: The City received a request to evaluate the intersection of Lupine Hills Drive and Portofino Drive/Roma Drive for an all-way stop for traffic calming purposes on Lupine Hills Drive.
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 Lupine Hills Drive and Portofino Drive/Roma 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 May 2023, staff collected data that showed the prevailing speeds on Lupine Hills Drive near Portofino Drive/Roma Drive to be around 34 miles per hour. The speed study is attached as Exhibit 5. There has been one reported accident on Lupine Hills Drive between Live Oak Road and Miramar Drive 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 Lupine Hills Drive. Exhibit 6 is a memorandum from the City Traffic Engineer documenting this determination.

Subject: All-Way Stop on Lupine Hills Drive and Portofino Drive / Roma Drive Residents submitted a petition to install an all-way stop at the intersection of Lupine Hills Drive and Portofino Drive / Roma Drive as a traffic calming measure on Lupine Hills Drive 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 Lupine Hills Drive and Portofino Drive / Roma 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 Lupine Hills Drive and Portofino Drive / Roma Drive is the most feasible and effective measure to reduce vehicle speeds on Lupine Hills Drive.
