Stop Sign Installation at 12 Locations
April 26, 2023
BACKGROUND:
Staff received public requests for the City to consider the installation of stop sign control at eleven T-intersections and one 4 -way intersection (all 12 of which are located within residential neighborhoods):
• Golden Crest Avenue at Erinlea Avenue (Attachment #1) • Homestake Place at Erinlea Avenue (Attachment #1)
• Comstock Place at Erinlea Avenue (Attachment #1)
• Erinlea Avenue at Antelope Place (Attachment #1)
• Mountain Trail Avenue at Golden Crest Avenue (Attachment #1) • Mountain Trail Avenue at Antelope Place (Attachment #1) • Prospector Place at Golden Crest Avenue (Attachment #1) • Antelope Place at Golden Crest Avenue (Attachment #1) • Deer Valley Avenue at Golden Crest Avenue (Attachment #1) • Remington Place at Deer Valley Avenue (Attachment #1) • Spring Canyon Place at Deer Valley Avenue (Attachment #1) • Campbell Avenue at Fordham Avenue (Attachment #2)
The City uses adopted g uidelines to regulate the use of stop signs, published in the California Manual of Uniform Traffic Control Devices (CA MUTCD).
The guidelines recommend the use of a st op sign facing the minor street o f the terminating leg of a T -intersection if certain conditions exist to better clarify and regulate right-of-way at an intersection. The 12 intersections evaluated by staff do not have stop signs posted at any of the approaches.
At T-intersections where stop or yield signs are not posted, Section 21800 of the Vehicle Code requires drivers approaching from the minor street (or the terminating leg) to stop and yield the right -of-way to vehicles on the major street (or through street). The City’s adopted practice is to add stop signs facing the terminating leg of a T -intersection to better clarify and remind motorists the need for vehicles approaching the intersection from the terminating street to yield the right-of-way to the uncontrolled cross street.
For the uncontrolled 4 -way intersection, CA MUTCD recommends stop signs be considered at the intersection of two minor streets where the intersection has more than three approaches, and the ability to see conflicting traffic on an approach is not sufficient to allow a road user to stop or yield in compliance with the normal right-of-way rule if su ch stopping or yielding is necessary. The roadway carrying the lowest volume of traffic should be stop controlled.
DISCUSSION/ANALYSIS:
Staff investigated traffic conditions at the 12 intersections and found that stop signs should be installed to better clarify the rules of the road at each intersection. Stop Stop Sign Installation at 12 Locations

signs are also recommended to mitigate sight distance issues such as corner landscaping, corner perimeter or structure walls, vehicles parked within driver sight lines, and horizontal or vertical road curvature.

The proposed stop signs at the 12 intersections in this report are not intended to control speeds or alleviate traffic volume concerns. The stop signs proposed at these intersections will be consistent with oth er intersections citywide that have stop sign control posted at the minor street or the terminating approach. It is a Stop Sign Installation at 12 Locations

“best engineering practice” to use stop signs to clarify and remind drivers of the proper rules of the road when they approach from the minor street. The Thousand Oaks Police Department has reviewed and concurred with the recommendations.
The Municipal Code provides that the City Council shall, by resolution, designate those intersections that are to be controlled by stop signs . T herefore, a recommendation to install the proposed stop signs at the 12 locations will be forwarded to the City Council with a proposed resolution (Attachment #4) and placed on a future City Council agenda for consideration.
Community Outreach: On April 20, 2023, a total of 161 notices were mailed to properties within proximity of the 12 proposed stop sign locations to advise residents of the proposed stop sign installations to be considered at the April 2 6, 2022, Traffic Commission meeting. The notified properties include the residents within a 300 -foot radius of the intersection of Campbell Avenue and For dham Avenue and the entire Deer Ridge Community located in the southeast quadrant below the intersection of Lynn Road and Wendy Drive. Obtaining community input is a key component of the installation of stop signs, when placed within a residential neighborhood.
