BACKGROUND
The City received a request from the Principal of Oak Meadows Elementary School to install all-way stop control at the intersection of Poinsettia Street and Nasturtium Lane due to the high volume of pedestrians crossing the intersection to access the school.
This intersection provides direct pedestrian access to the main entrance of Oak Meadows Elementary School. Currently, the intersection is uncontrolled and includes a yellow continental crosswalk on the east leg, along with school crossing signs and advance warning signs.
To evaluate existing conditions, traffic counts, including vehicle, pedestrian, and bicycle volumes, were collected on April 30, 2026, between 7:00 a.m. and 9:00 a.m. and between 2:00 p.m. and 6:00 p.m. to capture typical school-day traffic activity. The counts showed approximately 160 pedestrians crossing Poinsettia Street at this intersection during the morning peak hour and approximately 99 pedestrians during the afternoon peak hour.
Based on the significant pedestrian activity and the need to enhance safety for students and other pedestrians, staff recommends the installation of all-way stop control at the intersection.
The installation of all-way stop control is based on national and state standards outlined in the California Manual on Uniform Traffic Control Devices (CA MUTCD). In general, all-way stops are installed where:
• The volume of traffic on the intersecting roads are approximately equal.
• There is a documented history of collisions; and/or
• Sight distance limitations create unsafe conditions.
All-way stop control may also be installed where engineering study indicates that all-way stop control is needed due to other factors not addressed by warrants. These include:
• The need to control left-turn conflicts,
• At two residential streets of similar design and operating characteristics where all-way stop control would improve traffic operational characteristics of the intersection, or
• Where pedestrian and/or bicyclist movements support the installation of all-way stop control.
Based on the large number of pedestrians crossing at this location, staff recommends installing all-way stop control at the intersection of Poinsettia Street and Nasturtium Lane. Proposed improvements include the installation of stop signs on all approaches, “STOP” pavement markings, limit lines, advance warning signs, and the removal of any conflicting signs and pavement markings.
The proposed striping and signage improvements are expected to cost $5,500. Funding is available in the City’s Neighborhood Traffic Management Program (NTMP), CIP No. 8430 and will utilize Measure A and Gas Tax funds.
FISCAL IMPACT
None.
