6 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan The data analysis and review of existing
documents were supplemented by review
of collision reports and by comprehensive
site visits to observe roadway infrastructure
and traffic operations throughout the City.

Information collected through these activities
was incorporated into the Safety Action Plan.

Subsequently, a set of recommended safety
countermeasures were developed to address
the identified safety issues, and these
countermeasures were prioritized according to
the methodology described in this document.

The Safety Action Plan’s recommendations
include systemic countermeasures (which
can be implemented at multiple locations
throughout the City to address pervasive safety
issues) and location-specific countermeasures
(which address circumstances specific to their
locations). The prioritized list of countermeasures
in this document forms the Action Plan for Safe
Streets for All in the City of Irwindale.

To further inform the plan development, the following relevant plans and documents were reviewed and the Safety Action Plan was coordinated and aligned with their contents as applicable:

The City of Irwindale General Plan
The City of Irwindale Active Transportation Plan
The City of Irwindale Engineering and Traffic Survey
Caltrans Strategic Highway Safety Plan

2. VISION STATEMENT

AND GUIDING PRINCIPLES

2.1. SS4A Vision
Eliminate serious injury and fatal collisions by
creating a transportation network that provides
a comfortable environment for all users and all
modes, promotes traffic safety, and meets the
needs of the community.

2.1. SS4A Vision
Eliminate serious injury and fatal collisions
by creating a transportation network that
provides a comfortable environment for all
users and all modes, promotes traffic safety,
and meets the needs of the community.

1. Have zero fatal and severe injury
collisions on the city roadways

2. Reduce the number of pedestrian and
bicycle collisions on City roadways

3. Partner with traffic safety stakeholders
(fire, police, schools, parks, etc.) to
exchange information and ideas
specific to enhancing roadway safety
performance through engineering,
enforcement, and educational
strategies

4. Improve available collision data and
constantly monitor for improvements

5. Utilize community and traffic
safety stakeholder input to identify
opportunities to improve roadway
safety

6. Reduce the number of rear end,
broadside, and sideswipe collisions

7. Systemically implement safety
countermeasures proven to reduce
speeding and improper turning

2.2. SS4A Guiding Principles

9 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan A dataset of all reported collisions within the
City of Irwindale for a five-year period between
January 1, 2019 and December 31, 2023 was
analyzed to understand the history of collisions
and safety. Within this time period, there were
1,144 collisions in the City of Irwindale (excluding
those on I-210 and I-605). An overview of collision
locations is shown in Exhibit 3. In collision
reporting, the following standard categories are
used to define the severity of collision events:1
Fatality
Severe injury (an injury that prevents the
injured party from walking, driving, or
performing activities they were normally
capable of before the collision)
Other visible injury (an injury, other than
fatal or severe, that is evident to any person
at the collision scene)
Complaint of pain (injuries claimed but not
evident)
Property damage only

Turning (14%, meaning a driver made a turn
prohibited by signage, failed to use turn signals,
or turned at a distance too far from a curb),
and Automobile Right of Way Violation (13%,
meaning a maneuver that is made by a driver
without respecting the right-of-way of another
driver). For fatal and injury collisions, the three
most prevalent PCFs were Unsafe Speed (33%),
Traffic Signals and Signs (17%, meaning the
collision was caused by inadequate, inconsistent,
and/or confusing signage), and Automobile
Right of Way Violation (16%). The numbers and

26 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan Collisions on I-210 and I-605 are not included
in the Collision Trend Analysis because these
facilities are within Caltrans jurisdiction.

However, a basic overview of collision trends
on interstate/Caltrans highways within the City
of Irwindale’s corporate boundaries is included
here.

Between January 1, 2019 and December 31,
2023 there were 1,999 collisions on interstate
highways in Irwindale. Of these, there were 9
fatal collisions, 34 resulting in severe injury, 169
resulting in other visible injury, 357 resulting in
complaint of pain, and 1,430 resulting in property
damage only. The locations and collision severity
are shown on the map in Exhibit 26.

To establish the City’s high-injury network,
network screening was conducted. Network
screening is the process of studying safety
conditions throughout the entire road network of
the relevant jurisdiction. As in previous sections,
I-210 and I-605 were excluded from this analysis
due to being owned and maintained by Caltrans.

The network screening examines collision
trends at intersections and along corridors
(sections of roadway determined by logical
breaks in the road network, which are typically
major signalized intersections and the City
boundary). Consistent with standard practice
for road network safety studies, a radius of 300
feet around each intersection was used for the
analysis of intersection-related collisions, and a
buffer of 100 feet around each road centerline
was used for corridor collision analysis.

3.12. High-Injury
Network

3.13. EPDO Ranking
This analysis establishes the high-injury network based on the Equivalent Property Damage Only (EPDO) weighted score for intersections and corridors. To determine the EPDO ranking, a weighted score was assigned to each collision event based on updated EPDO weights consistent with those used in benefit-cost analysis for the Highway Safety Improvement Program (HSIP), as shown in Exhibit 27.

For intersections, the EPDO score was calculated based on collisions within a 300-foot radius of the intersection’s center. For corridors, the EPDO score per mile was calculated. The top 20 signalized intersections by EPDO rank are listed in Exhibit 28.

53 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan A project website was created on the Social
Pinpoint platform to inform the public about
the SS4A Action Plan and provide a platform
for community members to provide input. The
website included an online interactive map,
where stakeholders could submit comments
about road safety conditions associated with
specific travel modes and locations; and a
survey intended to collect data regarding road
safety conditions and needs in Irwindale.

Public outreach and stakeholder input played a substantial role in identifying the areas where transportation safety improvements are needed and ensuring community members were able to directly influence the development of the plan. A variety of outreach efforts were employed throughout the duration of the project, including in-person and virtual events and feedback opportunities. This section describes the project website that was created to gather community input and share project information; the community events that were held; and the inter- and intra-governmental coordination that took place.

4. PUBLIC AND STAKEHOLDER INPUT

4.1. Public Website and Survey
Publicization of the website was undertaken by
the City’s social media team. The website was
open for receiving comments from July 25 to
November 30, 2024. The website received 68
comments provided by multiple stakeholders
(including comments submitted from in-person
events), and 66 survey responses (including
surveys submitted at in-person events). The
modes associated with the comments are shown
in exhibit 33.. Exhibit 32 displays the top portion
of the homepage for the website, found at:
https://safetyplan.mysocialpinpoint.com/
irwindale-ss4a
Visitors to the page were invited to provide
comments on an interactive project map and
share their thoughts through a project survey.

Exhibit 32. Screenshot of interactive website homepage

54 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan The interactive map feature on the website
allowed the public to drag icons to a location
within the city and leave a comment regarding
driving, pedestrian, bicycle, or other suggestions
at that location. The comments on the interactive
map were integrated into the recommendations
in this SS4A. Exhibit 34 shows the interactive
map feature from the website.

Some of the top locations for public comment,
along with the common comment themes, are
listed below:

Irwindale Avenue directly west of City Hall:

Multiple complaints of speeding, a lack of
signage alerting vehicles to the presence
of children, and poorly timed crossings and

San Gabriel River Trail: Multiple complaints
about homeless encampments making
users feel unsafe on the trail, poor
connectivity between the trail and bike
routes on Peck Road and Myrtle Ave at the
Live Oak Avenue crossing, and multiple
requests for a bridge crossing Arrow
Highway due to feeling unsafe around highspeed vehicles and multiple collisions.

Arrow Highway: Complaints about a lack
of ADA-accessible crossings and sidewalks,
no bicycle connectivity, poor lighting, poor
striping, speeding, and distractions caused
by the palm trees in the median.

Overall: Many people expressed concerns
over speeding on both major roadways
and residential streets, poor pedestrian
crossings (particularly in terms of safety
for children), and other location-specific
comments like requests for red curbs, bad
roadway alignments (Irwindale Avenue
at Calle del Norte and Juarez Street), and
sidewalks and lighting.

on the website to gauge people’s travel patterns
in the city, their primary safety concerns in terms
of driver behavior and infrastructure, and what
they would like to see changed to make them
feel safer. In addition, paper surveys were filled
out by community members at both in-person
outreach events and put into the website. A
breakdown of the results is shown in Exhibit 35
through Exhibit 39.

58 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan Community members were also asked
what one thing they would do to improve
road safety in Irwindale. Answers included:

Improve Pedestrian and Crosswalk
Safety: Add safer pedestrian
crossings, including overpasses/
underpasses, better lighting, school
crossing guards, and enhanced
signage.

Expand and Protect Bike
Infrastructure: Build connected,
protected bike lanes, especially near
the Metro A Line, Santa Fe Dam, and
major streets, with safety-focused
designs to separate cyclists from
vehicles.

Enforce Speed Control: Implement
stricter speed zones, add speed
humps and feedback signs, and
increase traffic patrols to curb
speeding, particularly on Irwindale
Avenue and Cypress East.

Enhance Street Design: Introduce
traffic-calming measures like lane
reductions, medians, and shade trees,
especially near public facilities such
as the Metro station and Santa Fe
Dam.

Fix Infrastructure and Parking
Issues: Repair road surfaces, remove
excessive red curbs for better parking,
and clear streets of junk vehicles.

Educate and Promote Safety:

Provide public education on bike and
pedestrian etiquette while ensuring
the safety of vulnerable users,
including those visually impaired or in
wheelchairs.

The project team hosted two in-person events
and one virtual Zoom event to inform the public
about the SS4A plan and collect input about
transportation safety and concerns in Irwindale.

The first event was a pop-up table hosted at the
city’s “Music in the Park” event on August 1st,
2024, where community members congregated
at the park by City Hall to listen to free music
outdoors. Project team members printed out
bilingual fliers with project information and QR
codes to the website, and then handed them out
to attendees. In addition, bilingual surveys were
printed and filled out by 26 attendees and input
into the website by project staff.

4.2. Community Meetings
The second event was an open house-style
discussion at the Irwindale Senior Center on
October 3rd, 2024. Attendees were split up
into three tables where project staff hosted
roundtable discussions on safety concerns
and specific areas of the city they wanted to
see improvements in. Comments were written
on printed maps and input into the website by
project staff. Attendees were also asked to
provide contact information for future project
updates and to fill out printed surveys. The
event saw about 15 attendees, with 9 surveys
completed and 48 comments input on the map.

59 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan The third event was held virtually on Zoom on
November 21, 2024 to give community members
who were unable to attend in-person events an
opportunity to give feedback and learn about
the project. Project staff prepared a bilingual
presentation and advertised the event both on
social media and flyers at City facilities. Despite
the advertising, the event saw no attendees.

60 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan Project staff identified and established an
Implementation Group charged with the
plan’s development, implementation, and
monitoring, consisting of multi-disciplinary
stakeholders to provide insight, oversight,
and monitoring throughout the project’s
development and in the subsequent
implementation phase. Implementation
Group members included representatives
from the following entities:

City of Irwindale Public Works
Department
City of Irwindale Police Department
City of Irwindale Recreation
Department
City of Irwindale Community
Development
City of Irwindale Chamber of
Commerce
ActiveSGV
Los Angeles County Fire Department
Covina Valley Unified School District
San Gabriel Valley Council of
Governments (SGVCOG)
California Department of
Transportation (Caltrans)
Los Angeles County Metropolitan
Transportation Authority (Metro)
Foothill Transit
The Implementation Group met virtually over
Microsoft Teams five times between July
and December 2024, where members were
introduced to the project, given information
about the safety analysis, presented with initial
and updated countermeasures, updated on
outreach and public feedback, and kept up to
date on project progress. Implementation Group
members were also given the opportunity to
review and comment on the drafts of the final
planning document.

4.3. Implementation Group
In addition to providing guidance for the plan
development process, the Implementation
Group meetings also provided a venue for
inter- and intra-governmental cooperation and
collaboration, functioning as a meeting point for
representatives of various departments within
the City to meet and discuss safety issues, as
well as representatives of external and regional
stakeholder entities.

61 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan The tool uses 2020 census data to identify
the level of impact from each burden
on communities. According to the DOT,
disadvantaged communities are either any
census tract meeting the threshold for one or
more of the burden categories, or any federally
recognized tribe or tribal entity, regardless of if
they have land or not.

The USDOT’s Equitable Transportation
Community Explorer was created to showcase
and track data that identifies communities who
are disadvantaged from a lack of transportation
investment or other burdens, including: Climate
& Disaster Risk, Environmental, Health, and
Social. The tool is maintained by the DOT and
was created as a response to the Justice40
Initiative from the Biden Administration, or
Executive Order 14008.

The development of this plan and its recommended projects and strategies was shaped heavily by ensuring equity for all members of the community. Project staff used input from community outreach efforts and the Implementation Group to give as many community members as possible the opportunity to give feedback for the plan. In addition to seeking direct input from the community, the success of this plan and its focus on equity was shaped using multiple tools that provide quantitative and qualitative data showing disadvantages faced by different members of the community.

5. EQUITY CONSIDERATIONS

5.1. USDOT Equitable Transportation Community Explorer (ETC) As shown in Exhibit 45, when compared to
national data, Irwindale does not meet the
definition of a disadvantaged community.

However, it is considered disadvantaged in terms
of Environmental Burden (92%). Additionally,
under the Transportation Insecurity category,
Irwindale is considered disadvantaged for
Traffic Safety (100%), demonstrating that the
city has a major problem with safety.

62 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan Exhibit 45. USDOT ETC Explorer dashboard for Irwindale census block

63 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan The Climate and Economic Justice Screening
Tool was created in 2021 by the Council of
Environmental Quality to identify communities
considered disenfranchised or overburdened
across the following areas: Climate change,
Energy, Health, Housing, Legacy pollution,
Transportation, Water and wastewater, and
Workforce development. Communities are
considered disadvantaged by the tool under the
same qualifications used by the USDOT ETC tool.

As shown in Exhibit 46, according to the tool,
Irwindale is not considered a disadvantaged
community due to not meeting any burden
thresholds or at least one associated
socioeconomic threshold.

5.2. Climate and Economic Justice Screening Tool
Exhibit 46. Climate and Economic Justice Screening Tool results for Irwindale To be considered disadvantaged for
transportation, census tracts must:

Be at or above the 90th percentile for diesel
particulate matter exposure
OR
Transportation barriers
OR
Traffic proximity and volume
AND
Be at or above the 65th percentile for low
income.

64 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan The California Department of Transportation
(Caltrans) Transportation Equity Index (EQI) tool
was developed to identify transportation-based
priority areas by census tract through spatial
analysis.

Upon analysis, it was found that the EQI
tool did not screen Irwindale. Therefore, it is
underdetermined if Irwindale is considered a
transportation-based priority area.

Transportation
Equity Index (EQI)

5.4. Initial Equity
Assessment
The strategies, projects, and countermeasures
proposed in this Comprehensive Safety Action
Plan are primarily systemic, meaning that they
can be implemented at multiple locations that
have broadly similar roadway characteristics
and/or collision patterns. As such, it is expected
that the range of countermeasures, once
implemented, will not be concentrated in
any particular location and will benefit the
community as a whole. In the prioritization of
projects, emphasis was placed on projects
located in or near the residential areas of the
City and the areas near trail access points,
where more vulnerable road users (pedestrians,
bicyclists, and mobility aid users) are typically
present.

For a community to qualify, it must meet
the following criteria:

Median Household Income:
< HCD-defined low-income cutoff
OR
< 80% statewide median income
OR
Block intersects or is fully contained within
a Tribal Land

Best practices
Engineering judgment
Community and stakeholder input
The Action Items in this section are divided into
the following two categories:

Systemic countermeasures, which can be
implemented at multiple locations that have
broadly similar roadway characteristics
and/or collision patterns. These are typically
lower-cost action items that can be
implemented together as a single project,
incorporated into routine maintenance, or
added onto location-specific projects.

Location-specific countermeasures, which
address circumstances specific to their
locations.

The engineering Action Items recommended in
this section have been drawn from the following
sources:

for California’s Local Road Owners, Version

1.7, April 2024, created by Caltrans in
conjunction with FHWA and SafeTREC.

official traffic control devices in California.

6. STRATEGIES, PROJECTS,

AND COUNTERMEASURES
Countermeasures are listed in Exhibit 47 (for
intersections) and Exhibit 48 (for roadways).

This listing is followed by a detailed
description and conceptual illustration of each
countermeasure.

The majority of these countermeasures are
systemic. However, during the development
of the SS4A Plan, specific locations were
identified where certain countermeasures are
recommended. These are shown on the maps in
Exhibit 51 (for intersections) and Exhibit 52 (for
roadway corridors).

This section contains a comprehensive set of projects and strategies to address the safety problems identified in the Collision Trend Analysis, informed by data, evidence, best practices, public and stakeholder input, and equity considerations.

68 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan Systemic Countermeasures for Signalized Intersections
S1. Convert signal to mast arm (from
pedestal-mounted)
Intersections that have pedestal-mounted
signals may have poor visibility and can
result in vehicles not being able to stop in
time for a signal change. Providing better
visibility of intersection signs and signals
aids the drivers’ advance perception of the
upcoming intersection. Visibility and clarity
of the signal should be improved without
creating additional confusion or distraction
for drivers.

S2. Crosswalk visibility enhancements
High-visibility crosswalks use patterns (i.e.,
bar pairs, continental, ladder) that are
visible to both the driver and pedestrian
from farther away compared to traditional
transverse line crosswalks. They should
be considered at all midblock pedestrian
crossings and uncontrolled intersections.

Agencies should use materials such as inlay
or thermoplastic tape, instead of paint
or brick, for highly reflective crosswalk
markings.

S3. Improve signal hardware: lenses,
back-plates with retroreflective
borders, mounting, size, and number
Signalized intersections with a high
frequency of right-angle and rear-end
crashes occurring because drivers are
unable to see traffic signals sufficiently
in advance to safely negotiate the
intersection being approached. Signal
intersection improvements include new
LED lighting, signal back plates, retroreflective tape outlining the back plates, or visors to increase signal visibility, larger
signal heads, relocation of the signal
heads, or additional signal heads. Providing
better visibility of intersection signals aids
the drivers’ advance perception of the
upcoming intersection. Visibility and clarity
of the signal should be improved without
creating additional confusion for drivers.

69 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan S4. Improve signal timing (coordination,
phases, red, yellow, or operation)
Signalization improvements may include
adding phases, lengthening clearance
intervals, eliminating or restricting higherrisk movements, and coordinating signals at multiple locations. Certain timing, phasing,
and control strategies can produce multiple
safety benefits. Sometimes capacity
improvements come along with the safety
improvements and other times adverse
effects on delay or capacity occur. Corridor
improvements often have the highest
benefit but may take longer to implement.

Projects focused on capacity improvements
(without a separate focus on signal timing
safety needs) may not result in a reduction
in future crashes.

S5. Install near-side signal indicators
Near-side signal indicators are traffic
signal lights placed on the near side of an
intersection, supplementing those that are
mounted on the far side and/or overhead.

These signals are typically positioned close
to the point where vehicles or pedestrians
stop, so drivers or pedestrians can easily see
them when approaching the intersection. In
the case of near-side signals for vehicles,
they are often mounted on the same side
of the road as the approaching traffic
and are visible before the intersection
itself. This setup helps drivers anticipate
changes in the signal and prepare to stop
or go accordingly. Near-side signals are
commonly used in some urban areas or
places with complex intersections where
overhead signals might be obstructed (for
example, by large trucks) or less visible.

S6. Modify signal phasing to implement
a Leading Pedestrian Interval (LPI)
A leading pedestrian interval (LPI) gives
pedestrians the opportunity to enter an
intersection 3-7 seconds before vehicles
are given a green indication. With this head
start, pedestrians can better establish
their presence in the crosswalk before
vehicles have priority to turn right or left.

LPIs provide (1) increased visibility of
crossing pedestrians; (2) reduced conflicts
between pedestrians and vehicles; (3)
Increased likelihood of motorists yielding
to pedestrians; and (4) enhanced safety for
pedestrians who may be slower to start into
the intersection.

70 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan S7. Upgrade signing and striping
Upgrading the signing and striping at an
intersection involves improving or updating
road markings (striping) and traffic signs
(signing) to enhance safety, traffic flow, and
visibility. This can include adding, replacing,
or improving signs that are currently
damaged, deteriorated, or outdated, and
installing new ones to better guide traffic
and pedestrians. It also involves updating
lane markings, crosswalks, stop lines, and
other pavement markings to replace faded
or deteriorated paint markings and upgrade
the intersection to current standards.

S8. Daylight intersections (remove
obstacles to lines of sight by restricting
parking and removing fixed objects)
Daylighting, or removing visual obstructions
like parked cars or fixed objects in advance
of an intersection, can help prevent vehicles
from entering the intersection incorrectly
and increase visibility of pedestrians
crossing the street. Parking restriction
can include the removal of parking space
markings, installation of new “parking
prohibition” pavement markings or curb
paint, and signs. The minimum setback is
20 feet in advance of the crosswalk where
speeds are 25 mph or less, and 30 feet
where speeds are between 26 and 35 mph.

S9. Ensure lighting is adequate at
nighttime
Providing lighting at the intersection
itself, or both at the intersection and on
its approaches, improves the safety of an
intersection during nighttime conditions
by (1) making drivers more aware of the
surroundings at an intersection, which
improves drivers’ perception-reaction
times, (2) enhancing drivers’ available sight
distances, and (3) improving the visibility
of non-motorists. Intersection lighting is of
particular benefit to non-motorized users
as lighting not only helps them navigate the
intersection, but also helps drivers see them
better.

Systemic Countermeasures for Signalized Intersections

71 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan S10. Provide protected left turn phase
(left turn lane already exists)
Left turns are widely recognized as the
highest-risk movements at signalized
intersections. Providing Protected leftturn phases (i.e., the provision for a specific phase for a turning movement)
for signalized intersections with existing
left turn pockets can significantly improve
safety for left-turn maneuvers by removing
the need for the drivers to navigate through
gaps in oncoming/opposing through
traffic. Where left turn pockets are not
protected, the pedestrian and bicyclist
crossing phase often conflicts with these
left turn maneuvers. Protected left-turn
phases are warranted based on a number
of factors; agencies need to document their
consideration of the MUTCD, Section 4D.19.

S11. Increase the length of turn lanes
Increasing the length of an existing turn
lane to provide additional deceleration
and storage for turning vehicles can help
to address safety issues resulting from
queuing, such as crash history or observed
conflicts between vehicles waiting to turn
and vehicles proceeding straight. Extending
the lane may require additional right-ofway and utility relocation.

Systemic Countermeasures for Signalized Intersections

72 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan Systemic Countermeasures for Signalized Corridors
R1. Install raised median (with left turn
pockets as needed)
Upgrading the signing and striping at an
intersection involves improving or updating
road markings (striping) and traffic signs
(signing) to enhance safety, traffic flow, and
visibility. This can include adding, replacing,
or improving signs that are currently
damaged, deteriorated, or outdated, and
installing new ones to better guide traffic
and pedestrians. It also involves updating
lane markings, crosswalks, stop lines, and
other pavement markings to replace faded
or deteriorated paint markings and upgrade
the intersection to current standards.

R2. Install delineators, reflectors and/or
object markers
Daylighting, or removing visual obstructions
like parked cars or fixed objects in advance
of an intersection, can help prevent vehicles
from entering the intersection incorrectly
and increase visibility of pedestrians
crossing the street. Parking restriction
can include the removal of parking space
markings, installation of new “parking

20 feet in advance of the crosswalk where
speeds are 25 mph or less, and 30 feet
where speeds are between 26 and 35 mph.

R3. Install dynamic/variable speed
warning signs
This strategy primarily addresses crashes
caused by motorists traveling too fast
around sharp curves. It is intended to get
the drivers attention and give them a visual
warning that they may be traveling over the
recommended speed for the approaching
curve. Care should be taken to limit the
placement of these signs to help maintain
their effectiveness.

73 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan R4. Install/upgrade pedestrian crossing
(with enhanced safety features)
Adding pedestrian crossings has the
opportunity to greatly enhance pedestrian
safety at locations noted as being
problematic. The enhanced safety elements,
which may include curb extensions, medians
and pedestrian crossing islands, beacons,
and lighting, combined with pavement
markings delineating a portion of the
roadway that is designated for pedestrian
crossing. Care must be taken to warn drivers
of the potential for pedestrians crossing
the roadway and enhanced improvements
added to the crossing increase the likelihood
of pedestrians crossing in a safe manner.

R5. Remove or relocate fixed objects
outside of Clear Recovery Zone
While this strategy does not prevent
the vehicle leaving the roadway, it does
provide a mechanism to reduce the
severity of a resulting crash. A clear zone
is an unobstructed, traversable roadside
area that allows a driver to stop safely
or regain control of a vehicle that has left
the roadway. Removing or moving fixed
objects, flattening slopes, or providing
recovery areas reduces the likelihood of a
crash.

R6. Road Diet (Right-size wide no. 2
lanes by striping parking lanes or bike
lanes where feasible)
A Road Diet, or roadway reconfiguration,
can improve safety, calm traffic, provide
better mobility and access for all road
users, and enhance overall quality of life.

A Road Diet typically involves converting
an existing four-lane undivided roadway
to a three-lane roadway consisting of two
through lanes and a center two-way leftturn lane (TWLTL). The application of this strategy usually reduces the roadway
segment speeds and serious head-on
crashes. In many cases the extra pavement
width can be used for the installation of
bike lanes. In addition to increasing bicycle
safety, these bike lanes can improve the
safety of on-street parking.

Systemic Countermeasures for Signalized Corridors

74 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan R7. Ensure lighting is adequate at
nighttime
Providing roadway lighting improves
the safety during nighttime conditions
by (1) making drivers more aware of the
surroundings, which improves drivers’
perception-reaction times, (2) enhancing
drivers’ available sight distances to perceive
roadway characteristic in advance of the
change, and (3) improving non-motorist’s
visibility and navigation.

7. POLICY AND PROCESS CHANGES
During the process of developing the
Comprehensive Safety Action Plan, the City’s
current policies, plans, guidelines, and processes
were assessed. The following suggested policy
and process changes were identified as having
potential to improve road safety:

Enforce City Code Ch. 8.12 - Abandoned
or Inoperative Vehicles. In some locations
(specifically Alpha Street), it was found
through collision data analysis and site
visits that inoperative vehicles parked
on the street may be obstructing drivers’
view at intersections and driveways
and contributing to safety problems.

Enforcement of existing codes could help to
address this issue.

Enforce existing parking restrictions (red
curbs). Some areas were found to have
vehicles parked in violation of red curbing
and an association with increased collision
trends was observed. Enforcement of
parking restrictions could help to address
this issue.

Conduct a photometric study to assess
lighting adequacy. As shown in the Baseline
Analysis, 31% of collisions occurred at
night with streetlights operating. Based
on site observations, some streetlights are
operating but may not produce adequate
light. To further assess this, the City could
conduct a photometric study to assess
whether the following intersections are
adequately lit:

Arrow Hwy @ Irwindale Ave
Irwindale Ave @ Cll de Paseo
Irwindale Ave @ Juarez St
Irwindale Ave @ Tapia St / Martinez St
N Irwindale Ave @ Adelante St
In addition to the strategies listed in this plan,
the implementation of the above policy and
process changes could contribute to an overall
improvement in road safety.

8. PRIORITIZED ACTION PLAN
An essential part of the Safe Street for All
planning process is the prioritization of
strategies. This section presents the identified
engineering countermeasures for intersections
and corridors ranked according to priority. The
countermeasures were evaluated and prioritized
based on benefit-to-cost ratios following the
methodology prescribed in the current Caltrans
Local Road Safety Manual and using the HSIP
Analyzer for BCR applications provided by
Caltrans.

The prioritization of engineering
for the top ten high-injury intersections is shown
in Exhibit 49, and the prioritization of engineering
countermeasures for the top ten high-injury
corridors is shown in Exhibit 50.

Improper Turning

82 City of Irwindale - Safe Streets for All Comprehensive Safety Action Plan projects and programs to help meet the
requirements of the Clean Air Act. In some cases,
projects that improve safety may also meet
the criteria for CMAQ funding. The California
Office of Traffic Safety provides funding for nonengineering projects to improve safety, such as educational programs.

In addition, the City of Irwindale can look
for opportunities to incorporate safety
enhancements within the Capital Improvement
Program. This can be achieved primarily by
incorporating safety enhancements into routine
maintenance activities, such as periodic road
resurfacing projects. By integrating improved
safety practices into signing and striping and
related design elements when carrying out
scheduled resurfacing, the City can achieve
some safety improvements with minimal
additional cost.

With the adoption of this plan, the City of
Irwindale will be eligible for Implementation
Grant funding through the SS4A program.

Implementation Grants must be used to fund
projects and strategies from this plan within 5
years of agreements being signed.

The Highway Safety Improvement Program
provides grant funding to implement engineering
countermeasures. The HSIP Cycle 15 Call-forProjects will be announced in 2026. HSIP funds can pay for preliminary engineering, right of
way (must be less than 10% of construction
costs), and construction. Proposed projects are
evaluated based on the Benefit/Cost Ratios
(BCRs). All applications without fatal flaws are
prioritized in descending order, statewide, by the
BCRs.

The Active Transportation Program (ATP) funds
projects that further ATP goals, which relate to
increasing active transportation mode share
and safety. Infrastructure projects can be
funded, as well as plans and non-infrastructure
projects. Applications are scored on several
criteria, including an emphasis on safety.

The Bipartisan Infrastructure Law (BIL) continues
the Congestion Mitigation and Air Quality
Improvement Program (CMAQ) to provide
funding to local governments for transportation

Approved by:

Julian A. Miranda, City Manager
Background and Analysis:

Background
Assembly Bill (AB) 2561, codified under Government Code Section 3502.3, was enacted by the California Legislature and signed into law on September 22, 2024. It became effective on January 1, 2025. AB 2561 addresses the growing concern over job vacancies in local government, citing their negative impact on public service delivery and employee relations. The law mandates that public agencies annually assess and present information regarding workforce vacancies during a public hearing. This is intended to support transparency, improve staffing conditions, and strengthen labor relations.

Annual Reporting Requirements
In accordance with AB 2561, the following information must be reported publicly at least once per fiscal year:
• Current status of vacancies
• Recruitment and retention efforts
• Identification of any policy or procedural barriers affecting hiring If a single bargaining unit has a vacancy rate of 20% or higher, additional details must be disclosed:
• Total number of vacancies in that unit
• Total number of applicants for those vacancies
• Average number of applicants for those vacancies
• Opportunities to improve compensation and working conditions Workforce Overview
As of December 31, 2024, the City had a total of 137 budgeted full-time equivalent (FTE) positions, distributed as follows:

Vacancies in 2024
A total of 47 vacancies were created in calendar year 2024 due to various factors including new position approvals, internal promotions, separations, and retirements:

With an additional three vacancies carried over from 2023, the City conducted recruitment for 50 positions in 2024, of which 40 were successfully filled. The average vacancy rate for 2024 was 10%, with a year-end rate of 7.3%, broken down by group:

The following positions were vacant at the end of 2024, contributing to the 7.3% vacancy rate. All were filled between January and April 2025:
• Police Officer (3 FTE) – Filled February & April 2025 • Police Dispatcher/Clerk – Filled February 2025
• Associate Planner – Filled January 2025
• Permit Technician – Filled February 2025
• Assistant Planner – Filled January 2025
• Maintenance Aide (2 FTE) – Filled March 2025
• Part-time Tutor – Filled January 2025

Recruitment and Hiring Metrics for 2024
• New Hire Orientation: Conducted for 42 full-time/part-time employees and 15 seasonal Summer Youth Workers in 2024.
• Average Time to Hire: 46 - 150 calendar days. Extended timelines are primarily due to the Police Department’s rigorous background requirements in compliance with POST standards. • Applications Received: 1,676 for regular positions.
• Job Advertising: Vacancies were posted on GovernmentJobs.com, industry-specific sites, and mailed to all City residents.

The City provides a highly competitive compensation package. According to the most recent classification and compensation study, the City's total compensation exceeds the market median— primarily due to its exceptional health benefits. The City covers 100% of health, dental, and vision insurance premiums for employees and their eligible dependents. While base salaries are maintained at the market median, the overall value of the compensation package is significantly higher. However, many job seekers tend to focus only on base salary when evaluating opportunities. To better communicate the full value of employment with the City, more targeted recruitment messaging has been implemented to emphasize total compensation and benefits.

AB 2561 requires identification of any recruitment-related policy or procedural barriers. At this time, no such barriers have been identified. The City will continue to evaluate and refine processes to support efficient and effective hiring.

Recruitment and retention are critical to sustaining high-quality public services. In a competitive labor market, the City remains committed to hiring and retaining skilled employees who align with its mission and values. The Human Resources Department will continue to monitor, assess, and enhance strategies to reduce vacancies and support workforce stability.
