BACKGROUND
INFORMATION:
At the August 14, 2025, Orange
County Traffic Committee (Committee) meeting, the following items were
agendized and discussed:
Item A - All-Way
Stop Control
In March 2025, a fatal accident
occurred near the intersection of Skyline Drive and Hunting Horn Drive in North
Tustin. A southbound vehicle on Skyline Drive crossed the centerline, drove
over the sidewalk and struck a pedestrian walking her dog. Following the
incident, multiple residents contacted the Office of the Third Supervisorial
District to express concerns about traffic safety along Skyline Drive,
particularly citing issues related to speeding and limited sight distance at
intersections. In response, the Third District requested that OC Public Works
Traffic Engineering (OC Traffic) conduct a focused investigation of the
intersection.
According to the California Manual
on Uniform Traffic Control Devices (CA MUTCD) Section 2B.07, limited sight
distance may justify multi-way stop control if a driver cannot safely negotiate
the intersection without conflicting traffic also stopping. Based on this
guideline, an all-way stop control can be justified at this intersection.
The Committee reviewed the
evaluation and unanimously approved the recommendation to establish an all-way
stop control at the intersection of Skyline Drive and Hunting Horn Drive. The
recommendation includes installing stop signs, pavement markings and advanced
warning signs. The estimated cost for installing pavement markings and
appropriate signs is $1,500.
Item B - Remove
Parking Restrictions
OC Traffic received a request to
remove the existing timed parking restriction at 10462 Poona Drive in Anaheim,
prompted by increased demand for neighborhood parking.
In response, OC Traffic reviewed
historical records to understand the original justification. On July 17, 2003,
OC Traffic recommended implementing the timed parking restrictions because the
location operated as Arevalo’s Board and Care Home and required space for
patient loading and unloading. The recommendation was approved by the Committee
and subsequently adopted by the Board of Supervisors (Board) on September 9,
2003, via Resolution No. 03-296.
OC Traffic was unable to contact
the care facility via phone call, mail or in-person. The phone line was
disconnected and mailed correspondence was returned, suggesting the property is
now vacant. Based on these findings, staff concludes that the care facility is
no longer in operation and recommends the removal of the timed parking
restriction.
The Committee unanimously approved
to remove the timed parking restrictions in front of 10462 Poona Drive. The
estimated cost to remove the signage is $200.
Item
C - Bike Lanes
OC Traffic received a petition from
North Tustin residents seeking traffic-calming treatments on Prospect Avenue
near Loma Vista Elementary School. The petition cited excessive speeding in
school zones and safety issues at the crosswalk at Prospect Avenue and Carlsbad
Drive.
In response, OC Traffic partnered
with City of Tustin engineering staff to evaluate potential traffic-calming
options. The collaboration resulted in an agreement to reduce travel lane width
to 11 feet and install Class II buffered bike lanes. These enhancements will
connect existing bicycle facilities on Santa Clara Avenue and 17th Street,
improving connectivity for bicyclists. The buffered bike lanes also offer
pedestrian safety benefits by reducing the crossing distance from approximately
64 feet to 33 feet through physical separation between cyclists and vehicular
traffic.
The Committee unanimously approved to
establish Class II bike lanes at Prospect Avenue between 17th Street and
Santa Clara Avenue, including restriping and sign installation. The estimated
cost of restriping and signage is $30,000.
Item
D - One-Way Traffic
OC Traffic received a request from
OC Public Works Operations & Maintenance (O&M) regarding the roundabout
at Modjeska Canyon Road at the Tucker Wildlife Sanctuary parking area. O&M
reported that some drivers were navigating the roundabout clockwise, against
the intended counterclockwise flow, creating dangerous vehicle conflicts.
In response, OC Traffic conducted a
field investigation to evaluate existing conditions of the site. Staff observed
that the lack of directional signage at the roundabout creates confusion about
the intended circulation pattern. While most drivers follow a counterclockwise
direction, some travel clockwise, resulting in conflicts. Due to the narrow
travel way, two vehicles travelling in opposite directions cannot pass
side-by-side safely.
To improve traffic flow and reduce
confusion, the installation of “Keep Right” regulatory signs and object markers
at both the eastern and western ends of the roundabout is recommended to
establish a counterclockwise circulation.
The Committee unanimously approved
to establish one-way traffic on Modjeska Canyon Road, east of Tucker Wildlife
Sanctuary, beginning and ending at the parking lot. The estimated cost to
install signage and object markers is $1,000.
Item
E - Speed Limit
OC Traffic received numerous
concerns from Silverado residents regarding speeding along Silverado Canyon
Road, particularly near the Silverado Community Center and St. Michael’s Abbey.
Residents noted an increase in traffic volume and speeding following the
reopening of Maple Springs Trailhead, which had been previously closed due to
the Airport Fire.
In response, OC Traffic reviewed
the site conditions, including collision history, roadside geometry, speed and
volume. Currently, Silverado Canyon Road, west of Ladd Canyon Road, has no
posted speed limit and the statutory limit of 55 miles per hour (mph) per
California Vehicle Code (CVC) 22349(b) applies. For this study, said portion of
Silverado Canyon Road was separated into two segments: Santiago Canyon Road to
1.2 miles easterly (Segment 1) and 1.2 miles easterly of Santiago Canyon Road
to Ladd Canyon Road (Segment 2).
OC Traffic conducted an Engineering
and Traffic Survey to set the speed limit along each segment. Due to history of
speed related collisions and observed speeding, OC Traffic recommends a speed
limit of 45 mph for Segment 1 and a speed limit of 35 mph for Segment 2.
The Committee unanimously approved
the recommendations, which include installing speed limit signage and in-road
pavement markings. The estimated of implementation is $2,000.
Item
F - Speed Limit
On April 29, 2025, the Office of
the Fifth Supervisorial District held a Townhall meeting for the Rancho Mission
Viejo community to address residents’ concerns about traffic safety following a
recent fatal accident involving a bicyclist. Specific concerns focused on the
existing speed limits within the Sendero neighborhood (Sendero Way, Ascenso
Avenue, Ribera Road and Reata Road).
OC Traffic conducted an Engineering
and Traffic Survey on these streets to determine if a reduction was warranted.
Findings indicated that only Ascenso Avenue met the criteria for a 5 mph
reduction, in compliance with CA MUTCD and CVC guidelines. OC Traffic
recommended reducing the speed limit on Ascenso Avenue from 30 mph to 25 mph.
The Committee reviewed the evaluation and
unanimously approved the recommendation. The estimated cost to install signage
is $1,000.
Compliance
with CEQA:
The proposed project is categorically exempt (Class 1) from the provisions of
CEQA pursuant to CEQA Guidelines Section 15301, because it provides for the
minor alteration of existing public streets including addition of bicycle
facilities, involving negligible or no expansion of existing use.
FINANCIAL
IMPACT:
Appropriations for implementation
of the Recommended Actions are included in Fund 115, OC Road, FY 2025-2026
Budget.
