Roadside Design
Improvements at Curves
Horizontal curves account for 27 percent of all fatal crashes and 80 percent of all fatal crashes at curves are roadway departure crashes.1 Roadside design improvements at curves is a strategy encompassing several treatments that target the high-risk roadside environment along the outside of horizontal curves.
These treatments can reduce roadway departure fatalities and serious injuries by giving vehicles the opportunity to recover safely and by reducing crash severity.
Roadside design improvements can be implemented alone or in combination, and are particularly recommended at horizontal curves—where data indicates a higher risk for roadway departure fatalities and serious injuries.
Roadside Design Improvements to
Provide for a Safe Recovery
In cases where a vehicle leaves
the roadway, having strategic
roadside design elements, including
an added or widened shoulder,
flattened sideslopes, or a widened
clear zone can provide drivers with
an opportunity to regain control and
re-enter the roadway in their lane or
come to a safe stop before rolling
over or encountering a fixed object.
• 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. Agencies should
avoid adding new fixed objects
such as trees and utility cabinets or
poles in the clear zone. AASHTO’s
Roadside Design Guide details the
clear zone width adjustment factors
to be applied at horizontal curves.
• Slope flattening reduces the
steepness of the sideslope to
increase drivers’ ability to keep the
vehicle stable, regain control of the
vehicle, and avoid obstacles. Slopes
of 1V:4H or flatter are considered
recoverable (i.e., drivers can retain
control of a vehicle by slowing or
stopping). Slopes between 1V:3H
and 1V:4H are generally considered
traversable, but non-recoverable
(i.e., errant vehicle will continue to
the bottom of the slope).
• Adding or widening shoulders
gives drivers more recovery area
to regain control in the event of a
roadway departure.
Roadside Design Improvements to
Reduce Crash Severity
Since not all roadside hazards can be
removed, relocated, or redesigned
at curves, installing roadside barriers
to shield unmovable objects or steep
embankments may be an appropriate
treatment. Three common types of
roadside barriers are:
• Cable barrier
is a flexible barrier
made from steel cables mounted
on weak steel posts. Flexible barriers
are more forgiving and have the
most deflection.
• Metal-beam guardrail is a semi-
rigid barrier where a W-beam or
box-beam is mounted on steel
or timber posts. These deflect less
than cable barriers, so they can
be located closer to objects where
space is limited.
• Concrete barrier is a rigid barrier
that has little to no deflection.

Median Barriers
Median barriers are longitudinal barriers that separate opposing traffic on a divided highway and are designed to redirect vehicles striking either side of the barrier. Median barriers significantly reduce the number of cross-median crashes, which are attributed to the relatively high speeds that are typical on divided highways. AASHTO’s Roadside Design Guide (RDG) recommends guidelines for the use of median barriers on high-speed, fully controlled- access roadways for locations where the median is 30 ft in width or less and the average daily traffic (ADT) is greater than 20,000 vehicles per day (vpd).
For locations with median widths greater than 50 ft and where the ADT is less than 20,000 vpd, a median barrier is optional. For locations where the median is between 30 and 50 feet, the RDG suggests an analysis to determine the cost effectiveness of median barrier installation. Median barriers can be cable, metal-beam, or concrete.
• Cable barriers
are flexible barriers,
made from steel cables mounted
on weak steel posts, resulting in
less occupant impact force as it
absorbs energy from the crash,
capturing or redirecting the
vehicle. Due to larger deflection,
median width is an important
consideration. These barriers are
more adaptable to slopes typically
found in medians. Cable barriers
tend to require more frequent
maintenance and repair than
other barrier types.
• Metal-beam guardrails are
considered semi-rigid barriers,
where the W-beam or box-beam
is mounted to steel or timber
posts. When impacted, they are
designed to deform and deflect,
absorbing some of the crash
energy and redirecting the vehicle.
Metal-beam guardrails often do
not require maintenance after
minor impacts. They deflect less
than cable barriers, so they can
be located closer to objects where
space is limited.
• Concrete barriers are usually rigid
and result in little to no deflection.
They redirect rather than absorb
energy from the impact. Rigid
concrete barriers seldom require
repair or maintenance. Some
agencies have used portable
concrete barriers as median
barriers. These barriers require
repositioning after an impact but
are typically less maintenance than
a post mounted barrier.
To reduce cross-median crashes,
transportation agencies should
review their head-on crash history
on divided highways to identify hot
spots. Agencies should also consider
implementing a systemic approach
to median barrier placement based
on cross-median crash risk factors.
Potential risk factors include:
• Traffic volumes.
• Vehicle classifications.
• Median crossover history.
• Crash incidents.
• Vertical and horizontal alignment.
• Median terrain configurations.

Backplates with
Retroreflective Borders
Backplates added to a traffic signal head improve the visibility of the illuminated face of the signal by introducing a controlled-contrast background. The improved visibility of a signal head with a backplate is made even more conspicuous by framing it with a 1- to 3-inch yellow retroreflective border. Signal heads that have backplates equipped with retroreflective borders are more visible and conspicuous in both daytime and nighttime conditions.
This treatment is recognized as a
human factors enhancement of
traffic signal visibility, conspicuity,
and orientation for both older
and color vision deficient drivers.
This countermeasure is also
advantageous during periods of
power outages when the signals
would otherwise be dark, providing a
visible cue for motorists to stop at the
intersection ahead.
Considerations
Transportation agencies should
consider backplates with
retroreflective borders as part
of their efforts to systematically
improve safety performance at
signalized intersections. Adding a
retroreflective border to an existing
signal backplate is a very low-cost
safety treatment. This can be done
by either adding retroreflective
tape to an existing backplate or
purchasing a new backplate with
a retroreflective border already
incorporated. The most efficient
means of implementing this proven
safety countermeasure is to adopt
it as a standard treatment for
signalized intersections across a
jurisdiction or State.
Implementation challenges
include minimizing installation time,
accessing existing signal heads, and
structural limitations due to added
wind load in instances where an
entire backplate is added. Agencies
should consider the design of the
existing signal support structure to
determine if the design is sufficient to
support the added wind load.

Corridor Access
Management
Access management refers to the design, application, and control of entry and exit points along a roadway. This includes intersections with other roads and driveways that serve adjacent properties. Thoughtful access management along a corridor can simultaneously enhance safety for all modes, facilitate walking and biking, and reduce trip delay and congestion.
Every intersection, from a signalized
intersection to an unpaved driveway,
has the potential for conflicts
between vehicles, pedestrians, and
bicyclists. The number and types of
conflict points—locations where the
travel paths of two users intersect—
influence the safety performance of
the intersection or driveway. FHWA
developed corridor-level crash
prediction models to estimate and
analyze the safety effects of selected
access management techniques
for different area types, land uses,
roadway variables, and traffic
volumes.1
The following access management
strategies can be used individually or
in combination with one another:
• Reduce density through driveway
closure, consolidation, or
relocation.
• Manage spacing of intersection
and access points.
• Limit allowable movements at
driveways (such as right-in/
right-out only).
• Place driveways on an intersection
approach corner rather than a
receiving corner, which is expected
to have fewer total crashes.2
• Implement raised medians
that preclude across-roadway
movements.
• Utilize designs such as roundabouts
or reduced left-turn conflicts
(such as restricted crossing U-turn,
median U-turns, etc.).
• Provide turn lanes (i.e., left-only,
right-only, or interior two-way left).
• Use lower speed one-way or two-
way off-arterial circulation roads.
Successful corridor access
management involves balancing
overall safety and mobility for
all users along with the needs of
adjacent land uses.

Dedicated Left- and
Right-Turn Lanes at Intersections
Auxiliary turn lanes—either for left turns or right turns—provide physical separation between turning traffic that is slowing or stopped and adjacent through traffic at approaches to intersections. Turn lanes can be designed to provide for deceleration prior to a turn, as well as for storage of vehicles that are stopped and waiting for the opportunity to complete a turn.
While turn lanes provide measurable
safety and operational benefits at
many types of intersections, they
are particularly helpful at two-way
stop-controlled intersections. Crashes
occurring at these intersections are
often related to turning maneuvers.
Since the major route traffic is free
flowing and typically travels at higher
speeds, crashes that do occur are
often severe. The main crash types
include collisions of vehicles turning
left across opposing through traffic
and rear-end collisions of vehicles
turning left or right with other vehicles
following closely behind. Turn lanes
reduce the potential for these types
of crashes.
Installing left-turn lanes and/or right-
turn lanes should be considered
for the major road approaches
for improving safety at both three-
and four-leg intersections with stop
control on the minor road, where
significant turning volumes exist,
or where there is a history of turn-
related crashes. Pedestrian and
bicyclist safety and convenience
should also be considered when
adding turn lanes at an intersection.
Specifically, offset left- and right-turn
lanes will lengthen crossing distances
for pedestrians.
Offset Turn Lanes
Providing offset of left- and right-
turn lanes to increase visibility can
provide added safety benefits, and
is preferable in many situations,
particularly at locations with higher
speeds, or where free-flow or
permissive movements are possible.
At turn lanes with zero or negative
offset, turning vehicles can block
sightlines. For left-turn lanes, this
usually involves opposing left-turning
vehicles occupying the turn lanes
at the same time. For right-turn
lanes, this typically involves right-
turning vehicles from the major
road and vehicles entering the
intersection from the minor road.
In both scenarios, adding positive
offset to turn lanes enhances the
sight distance to approaching
vehicles that conflict with the turning
movement. Offset turn lanes should
be considered when there is a high
frequency of these types of conflicts
in order to reduce the likelihood of a
severe crash.

Reduced Left-Turn
Conflict Intersections
Reduced left-turn conflict intersections are geometric designs that alter how left-turn movements occur. These intersections simplify decision-making for drivers and minimize the potential for higher severity crash types, such as head-on and angle. Two highly effective designs that rely on U-turns to complete certain left-turn movements are known as the Restricted Crossing U-turn (RCUT) and the Median U-turn (MUT).
Restricted Crossing U-turn
The RCUT intersection, also known
as a J-Turn, Superstreet, or Reduced
Conflict Intersection, modifies
the direct left-turn and through
movements from cross-street
approaches. Minor road traffic makes
a right turn followed by a U-turn at a
designated location—either signalized
or unsignalized—to continue in
the desired direction. The RCUT is
suitable for and adaptable to a wide
variety of circumstances, ranging
from isolated rural, high-speed
locations to urban and suburban
high-volume, multimodal corridors.
It is a competitive and less costly
alternative to constructing an
interchange. RCUTs work well
when consistently used along
a corridor, but also can be
used effectively at individual
intersections. Studies have
shown that installing an RCUT
can result in a 30-percent
increase in throughput and a
40-percent reduction in network
intersection travel time.
1 Median U-turn
The MUT intersection modifies
direct left turns from the major
approaches. Vehicles proceed
through the main intersection,
make a U-turn a short distance
downstream, followed by a right
turn at the main intersection.
The U-turns can also be used for
modifying the cross-street left turns,
similar to the RCUT.
The MUT is an excellent choice for
intersections with heavy through
traffic and moderate left-turn
volumes. Studies have shown a
20- to 50-percent improvement in
intersection throughput for various
lane configurations as a result of
implementing the MUT design. When
implemented at multiple intersections
along a corridor, the efficient two-
phase signal operation of the MUT
can reduce delay, improve travel
times, and create more crossing
opportunities for pedestrians and
bicyclists.

Roundabouts
The modern roundabout is an intersection with a circular configuration that safely and efficiently moves traffic. Roundabouts feature channelized, curved approaches that reduce vehicle speed, entry yield control that gives right-of- way to circulating traffic, and counterclockwise flow around a central island that minimizes conflict points. The net result of lower speeds and reduced conflicts at roundabouts is an environment where crashes that cause injury or fatality are substantially reduced.
Roundabouts are not only a safer
type of intersection; they are also
efficient in terms of keeping people
moving. Even while calming traffic,
they can reduce delay and queuing
when compared to other intersection
alternatives. Furthermore, the lower
vehicular speeds and reduced
conflict environment can create
a more suitable environment for
walking and bicycling.
Roundabouts can be implemented
in both urban and rural areas under
a wide range of traffic conditions.
They can replace signals, two-
way stop controls, and all-way
stop controls. Roundabouts are an
effective option for managing speed
and transitioning traffic from high-
speed to low-speed environments,
such as freeway interchange ramp
terminals, and rural intersections
along high-speed roads.

Systemic Application
of Multiple Low-Cost Countermeasures
at Stop-Controlled Intersections
This systemic approach to intersection safety involves deploying a package of multiple low-cost countermeasures, including enhanced signing and pavement markings, at a large number of stop-controlled intersections within a jurisdiction. These countermeasures increase driver awareness and recognition of the intersections and potential conflicts.
There are several benefits to
systemically applying multiple
low-cost countermeasures at stop-
controlled intersections, including,
• Resources are maximized because
the treatments are low cost.
• A high number of intersections can
receive treatment.
• Improvements are highly cost-
effective, with an average benefit-
cost ratio of 12:1, even assuming a
conservative 3-year service life.
The low-cost countermeasures
for stop-controlled intersections
generally consist of the following
treatments:
On the Through Approach
• Doubled-up (left and right),
oversized advance intersection
warning signs, with supplemental
street name plaques (can also
include flashing beacon).
• Retroreflective sheeting on sign
posts.
• Enhanced pavement markings that
delineate through lane edge lines.
On the Stop Approach
• Doubled-up (left and right),
oversized advance “Stop Ahead”
intersection warning signs (can also
include flashing beacon).
• Doubled-up (left and right),
oversized Stop signs.
• Retroreflective sheeting on sign
posts.
• Properly placed stop bar.
• Removal of vegetation, parking,
or obstructions that limit sight
distance.
• Double arrow warning sign at stem
of T-intersections.

Yellow Change
Intervals
At a signalized intersection, the yellow change interval is the length of time that the yellow signal indication is displayed following a green signal indication. The yellow signal confirms to motorists that the green has ended and that a red will soon follow.
1 Federal Highway Administration. “Automated Traffic Signal Performance,” (2020). 2 (CMF ID:
380,384
) NCHRP Report 731: Guidelines for Timing Yellow and All-Red Intervals at Signalized Intersections, (2011).
Since red-light running is a leading
cause of severe crashes at signalized
intersections, it is imperative that
the yellow change interval be
appropriately timed. Too brief an
interval may result in drivers being
unable to stop safely and cause
unintentional red-light running.
Too long of an interval may result
in drivers treating the yellow as
an extension of the green phase
and invite intentional red-light
running. Factors such as the speed
of approaching and turning
vehicles, driver perception-reaction
time, vehicle deceleration, and
intersection geometry should all be
considered in the timing calculation.
Transportation agencies can improve
signalized intersection safety and
reduce red-light running by reviewing
and updating their traffic signal
timing policies and procedures
concerning the yellow change
interval. Agencies should institute
regular evaluation and adjustment
protocols for existing traffic signal
timing. Refer to the Manual on
Uniform Traffic Control Devices for
basic requirements and further
recommendations about yellow
change interval timing. As part of
strategic signal system modernization
and updates, incorporating
automated traffic signal
performance measures (ATSPMs) is
a proven approach to improve on
traditional retiming processes. ATSPMs
provide continuous performance
monitoring capability and the ability
to modify timing based on actual
performance, without requiring
expensive modeling or data
collection.1

Crosswalk Visibility
Enhancements
Poor lighting conditions, obstructions such as parked cars, and horizontal or vertical roadway curvature can reduce visibility at crosswalks, contributing to safety issues. For multilane roadway crossings where vehicle volumes are in excess of 10,000 Average Annual Daily Traffic (AADT), a marked crosswalk alone is typically not sufficient. Under such conditions, more substantial crossing improvements could prevent an increase in pedestrian crash potential.
Three main crosswalk visibility enhancements help make crosswalks and the pedestrians, bicyclists, wheelchair and other mobility device users, and transit users using them more visible to drivers. These include high-visibility crosswalks, lighting, and signing and pavement markings. These enhancements can also assist users in deciding where to cross. Agencies can implement these features as standalone or combination enhancements to indicate the preferred location for users to cross.
High-visibility crosswalks
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.
Improved Lighting
The goal of crosswalk lighting
should be to illuminate with positive
contrast to make it easier for a driver
to visually identify the pedestrian.
This involves carefully placing the
luminaires in forward locations to
avoid a silhouette effect of the
pedestrian.
Enhanced Signing and
Pavement Markings
On multilane roadways, agencies
can use “YIELD Here to Pedestrians”
or “STOP Here for Pedestrians”
signs 20 to 50 feet in advance of
a marked crosswalk to indicate
where a driver should stop or yield to
pedestrians, depending on State law.
To supplement the signing, agencies
can also install a STOP or YIELD bar
(commonly referred to as “shark’s
teeth“) pavement markings.
In-street signing, such as “STOP Here
for Pedestrians” or “YIELD Here to
Pedestrians” may be appropriate on
roads with two- or three-lane roads
where speed limits are 30 miles per
hour or less.

Bicycle Lanes
Most fatal and serious injury bicyclist crashes occur at non-intersection locations.
Nearly one-third of these crashes occur when motorists are overtaking bicyclists1 because the speed and size differential between vehicles and bicycles can lead to severe injury. Many people are not comfortable riding a bicycle because of their fear that this type of crash may occur. To make bicycling safer and more comfortable for most types of bicyclists, State and local agencies should consider installing bicycle lanes. Providing bicycle facilities can mitigate or prevent interactions, conflicts, and crashes between bicyclists and motor vehicles, and create a network of safer roadways for bicycling. Bicycle Lanes align with the Safe System Approach principle of recognizing human vulnerability—where separating users in space can enhance safety for all road users.
Applications
The FHWA’s
Bikeway Selection Guide
and
Incorporating On-Road Bicycle
Networks into Resurfacing Projects
assist agencies in determining which
facilities provide the most benefit in
various contexts. Bicycle lanes can be
included on new roadways or created
on existing roads by reallocating
space in the right-of-way through
Road Diets. Separated bicycle lanes,
which use vertical elements—such
as flexible delineator posts, curbs, or
vegetation—between the bicycle
lane and motorized traffic lanes
provide additional safety benefits.2,3
For a marked bike lane without vertical
elements, a lateral offset with marked
buffer can help to further separate
bicyclists from vehicle traffic.
Considerations
• In order to maximize a roadway’s
suitability for riders of all ages
and abilities, bicycle lane design
should vary according to roadway
characteristics (number of lanes,
motor vehicle and truck volumes,
speed, presence of transit), user needs
(current and forecasted ridership,
types of bicycles and micromobility
devices in use within the community,
role within the bicycling network), and
land-use context (adjacent land uses,
types and intensity of conflicting uses,
demands from other users for curbside
access). Separated bicycle lanes are
recommended on roadways with
higher vehicle volumes and speeds,
such as arterials.
• City and State policies may require
minimum bicycle lane widths,
although desirable bicycle lane widths
can differ by agency and functional
classification of the road, current
and forecasted bicycle volumes,
and contextual attributes such as
topography.
• Studies have found that roadways did
not experience an increase in crashes
or congestion when travel lane widths
were decreased to add a bicycle
lane.4
• Studies and experience in U.S. cities
show that bicycle lanes increase
ridership and may help jurisdictions
better manage roadway capacity.
• In rural areas, rumble strips can
negatively impact bicyclists’ ability to
ride if not properly installed. Agencies
should consider the dimensions,
placement, and offset of rumble strips
when adding a bicycle lane.5
• Bicycle lanes should be considered on
roadways where adjacent land use
suggests that trips could be served by
varied modes, particularly to meet the
safety and travel needs of low-income
populations likely to use bicycles to
reach essential destinations.6

Rectangular Rapid
Flashing Beacons (RRFB)
A marked crosswalk or pedestrian warning sign can improve safety for pedestrians crossing the road, but at times may not be sufficient for drivers to visibly locate crossing locations and yield to pedestrians. To enhance pedestrian conspicuity and increase driver awareness at uncontrolled, marked crosswalks, transportation agencies can install a pedestrian actuated Rectangular Rapid Flashing Beacon (RRFB) to accompany a pedestrian warning sign. RRFBs consist of two, rectangular- shaped yellow indications, each with a light-emitting diode (LED)-array-based light source.1 RRFBs flash with an alternating high frequency when activated to enhance conspicuity of pedestrians at the crossing to drivers.
For more information on using RRFBs, see the Interim Approval in the Manual on Uniform Traffic Control Devices (MUTCD).1

4 (CMF ID:
9024
) NCHRP Research Report 841 Development of Crash Modification Factors for Uncontrolled Pedestrian Crossing Treatments, (2017).
Applications
The RRFB is applicable to many
types of pedestrian crossings but is
particularly effective at multilane
crossings with speed limits less
than 40 miles per hour.2 Research
suggests RRFBs can result in motorist
yielding rates as high at 98 percent
at marked crosswalks, but varies
depending on the location, posted
speed limit, pedestrian crossing
distance, one- versus two-way road,
and the number of travel lanes.3
RRFBs can also accompany school or
trail crossing warning signs.
RRFBs are placed on both sides of
a crosswalk below the pedestrian
crossing sign and above the
diagonal downward arrow plaque
pointing at the crossing.1 The flashing
pattern can be activated with
pushbuttons or passive (e.g., video or
infrared) pedestrian detection, and
should be unlit when not activated.
Considerations
Agencies should:2
• Install RRFBs in the median rather
than the far-side of the roadway
if there is a pedestrian refuge or
other type of median.
• Use solar-power panels to eliminate
the need for a power source.
• Reserve the use of RRFBs for
locations with significant pedestrian
safety issues, as over-use of RRFB
treatments may diminish their
effectiveness.
Agencies shall not:2
• Use RRFBs without the presence of
a pedestrian, school or trail crossing
warning sign.
• Use RRFBs for crosswalks across
approaches controlled by YIELD
signs, STOP signs, traffic control
signals, or pedestrian hybrid
beacons, except for the approach
or egress from a roundabout.

Leading Pedestrian
Interval
A leading pedestrian interval (LPI) gives pedestrians the opportunity to enter the crosswalk at an intersection 3-7 seconds before vehicles are given a green indication. Pedestrians can better establish their presence in the crosswalk before vehicles have priority to turn right or left .
LPIs provide the following benefits:
• Increased visibility of crossing
pedestrians.
• Reduced conflicts between
pedestrians and vehicles.
• Increased likelihood of motorists
yielding to pedestrians.
• Enhanced safety for pedestrians
who may be slower to start into the
intersection.
FHWA’s Handbook for
Designing
Roadways for the Aging Population
recommends the use of the LPI at
intersections with high turning vehicle
volumes. Transportation agencies
should refer to the Manual on Uniform
Traffic Control Devices for guidance on
LPI timing and ensure that pedestrian
signals are accessible for all users.
Costs for implementing LPIs are very
low when only signal timing alteration
is required.

Medians and
Pedestrian Refuge Islands in Urban
and Suburban Areas
A median is the area between opposing lanes of traffic, excluding turn lanes. Medians in urban and suburban areas can be defined by pavement markings, raised medians, or islands to separate motorized and non- motorized road users.
A pedestrian refuge island (or crossing area) is a median with a refuge area that is intended to help protect pedestrians who are crossing a road. 1 National Center for Statistics and Analysis. (2020, March). Pedestrians:

Pedestrian crashes account for
approximately 17 percent of all traffic
fatalities annually, and 74 percent
of these occur at non-intersection
locations.1 For pedestrians to
safely cross a roadway, they must
estimate vehicle speeds, determine
acceptable gaps in traffic based
on their walking speed, and predict
vehicle paths. Installing a median
or pedestrian refuge island can
help improve safety by allowing
pedestrians to cross one direction of
traffic at a time.
Transportation agencies should
consider medians or pedestrian
refuge islands in curbed sections of
urban and suburban multilane
roadways, particularly in areas with
a significant mix of pedestrian and
vehicle traffic, traffic volumes over
9,000 vehicles per day, and travel
speeds 35 mph or greater. Medians/
refuge islands should be at least
4-ft wide, but preferably 8 ft for
pedestrian comfort. Some example
locations that may benefit from
medians or pedestrian refuge islands
include:
• Mid-block crossings.
• Approaches to multilane
intersections.
• Areas near transit stops or other
pedestrian-focused sites.

Pedestrian Hybrid
Beacons
The pedestrian hybrid beacon (PHB) is a traffic control device designed to help pedestrians safely cross higher-speed roadways at midblock crossings and uncontrolled intersections. The beacon head consists of two red lenses above a single yellow lens. The lenses remain “dark” until a pedestrian desiring to cross the street pushes the call button to activate the beacon, which then initiates a yellow to red lighting sequence consisting of flashing and steady lights that directs motorists to slow and come to a stop, and provides the right- of-way to the pedestrian to safely cross the roadway before going dark again. 1 National Center for Statistics and Analysis. (2020, March). Pedestrians:

) Fitzpatrick, K. and Park, E.S. Safety Effectiveness of the HAWK Pedestrian Crossing Treatment, FHWA-HRT-10-042, (2010).
Nearly 74 percent of pedestrian
fatalities occur at non-intersection
locations, and vehicle speeds are
often a major contributing factor.1
As a safety strategy to address this
pedestrian crash risk, the PHB is an
intermediate option between a
flashing beacon and a full pedestrian
signal because it assigns right of way
and provides positive stop control. It
also allows motorists to proceed once
the pedestrian has cleared their side
of the travel lane(s), reducing vehicle
delay.
Transportation agencies should refer
to the Manual on Uniform Traffic Control
Devices (MUTCD) for information on
the application of PHBs. Transportation
agencies should locate pedestrian
signals to be accessible for all users.
In general, PHBs are used where it
is difficult for pedestrians to cross
a roadway, such as when gaps in
traffic are not sufficient or speed
limits exceed 35 miles per hour.
They are very effective at locations
where three or more lanes will
be crossed or traffic volumes are
above 9,000 annual average daily
traffic. Installation of a PHB must
also include a marked crosswalk
and pedestrian countdown signal.
If PHBs are not already familiar to a
community, agencies should conduct
appropriate education and outreach
as part of implementation.Example of PHBs mounted

Road Diets
(Roadway Reconfiguration)
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 left-turn lane (TWLTL).
Benefits of Road Diet installations
may include:
• Reduction of rear-end and left-turn
crashes due to the dedicated
left-turn lane.
• Reduced right-angle crashes as
side street motorists cross three
versus four travel lanes.
• Fewer lanes for pedestrians to
cross.
• Opportunity to install pedestrian
refuge islands, bicycle lanes,
on-street parking, or transit stops.
• Traffic calming and more consistent
speeds.
• A more community-focused,
Complete Streets environment that
better accommodates the needs
of all road users.
A Road Diet can be a low-cost
safety solution when planned in
conjunction with a simple pavement
overlay, and the reconfiguration can
be accomplished at no additional
cost. Typically, a Road Diet is
implemented on a roadway with
a current and future average daily
traffic of 25,000 or less.

Walkways
A walkway is any type of defined space or pathway for use by a person traveling by foot or using a wheelchair. These may be pedestrian walkways, shared use paths, sidewalks, or roadway shoulders.
With more than 6,200 pedestrian
fatalities and 75,000 pedestrian
injuries occurring in roadway
crashes annually,1 it is important for
transportation agencies to improve
conditions and safety for pedestrians
and to integrate walkways more
fully into the transportation system.
Research shows people living in low-
income communities are less likely
to encounter walkways and other
pedestrian-friendly features.2
Well-designed pedestrian walkways,
shared use paths, and sidewalks
improve the safety and mobility of
pedestrians. Pedestrians should have
direct and connected network of
walking routes to desired destinations
without gaps or abrupt changes. In
some rural or suburban areas, where
these types of walkways are not
feasible, roadway shoulders provide
an area for pedestrians to walk next
to the roadway, although these are
not preferable.
Transportation agencies should work
towards incorporating pedestrian
facilities into all roadway projects
unless exceptional circumstances
exist. It is important to provide and
maintain accessible walkways along
both sides of the road in urban areas,
particularly near school zones and
transit locations, and where there is a
large amount of pedestrian activity.
Walkable shoulders should also be
considered along both sides of rural
highways when routinely used by
pedestrians.

Pavement Friction
Management
Friction is a critical characteristic of a pavement that affects how vehicles interact with the roadway, including the frequency of crashes. Measuring, monitoring, and maintaining pavement friction—especially at locations where vehicles are frequently turning, slowing, and stopping—can prevent many roadway departure, intersection, and pedestrian-related crashes.
Pavement friction treatments, such as High Friction Surface Treatment (HFST), can be better targeted and result in more efficient and effective installations when using continuous pavement friction data along with crash and roadway data.
Continuous Pavement Friction
Measurement
Friction data for safety performance
is best measured with Continuous
Pavement Friction Measurement
(CPFM) equipment. Spot friction
measurement devices, like locked-
wheel skid trailers, cannot safely and
accurately collect friction data in
curves or intersections, where the
pavement polishes more quickly and
adequate friction is so much more
critical. Without CPFM equipment,
agencies will assume the same
friction over a mile or more.
CPFM technology measures friction
continuously at highway speeds and
provides both network and segment
level data. Practitioners can analyze
the friction, crash, and roadway data
to better understand and predict
where friction-related crashes will
occur to better target locations and
more effectively install treatments.1
High Friction Surface Treatment
HFST consists of a layer of durable,
anti-abrasion, and polish-resistant
aggregate over a thermosetting
polymer resin binder that locks the
aggregate in place to restore or
enhance friction and skid resistance.
Calcined bauxite is the aggregate
shown to yield the best results
and should be used with HFST
applications.
Applications
HFST should be applied in locations
with increased friction demand,
including:
• Horizontal curves.
• Interchange ramps.
• Intersection approaches.
o Higher-speed signalized and
stop-controlled intersections.
o Steep downward grades.
• Locations with a history of rear-end,
failure to yield, wet-weather, or red-
light-running crashes.
• Crosswalk approaches.
Considerations
• HFST is applied on existing pavement,
so no new pavement is added.
• If the underlying pavement
structure is unstable, then the
HFST life cycle may be shortened,
resulting in pre-mature failure.
• The automated installation method
is preferred as it minimizes issues
often associated with manual
installation: human error due to
fatigue, inadequate binder mixing,
improper and uneven binder
thickness, delayed aggregate
placement, and inadequate
aggregate coverage.
• The cost can be reduced when
bundling installations at multiple
locations.

Lighting
The number of fatal crashes occurring in daylight is about the same as those that occur in darkness. However, the nighttime fatality rate is three times the daytime rate because only 25 percent of vehicle miles traveled (VMT) occur at night. At nighttime, vehicles traveling at higher speeds may not have the ability to stop once a hazard or change in the road ahead becomes visible by the headlights. Therefore, lighting can be applied continuously along segments and at spot locations such as intersections and pedestrian crossings in order to reduce the chances of a crash.
Adequate lighting (i.e., at or above minimum acceptable standards) is based on research recommending horizontal and vertical illuminance levels to provide safety benefits to all users of the roadway environment. Adequate lighting can also provide benefits in terms of personal security for pedestrians, wheelchair and other mobility device users, bicyclists, and transit users as they travel along and across roadways.
Applications
Roadway Segments
Research indicates that continuous
lighting on both rural and urban
highways (including freeways) has
an established safety benefit for
motorized vehicles.1 Agencies can
provide adequate visibility of the
roadway and its users through the
uniform application of lighting that
provides full coverage along the
roadway and the strategic placement
of lighting where it is needed the most.
Intersections and Pedestrian
Crossings
Increased visibility at intersections at
nighttime is important since various
modes of travel cross paths at these
locations. Agencies should consider
providing lighting to intersections
based on factors such as a history of
crashes at nighttime, traffic volume,
the volume of non-motorized users,
the presence of crosswalks and raised
medians, and the presence of transit
stops and boarding volumes.
Considerations
Most new lighting installations are
made with breakaway features,
shielded, or placed far enough
from the roadway to reduce
the probability and/or severity
of fixed-object crashes. Modern
lighting technology gives precise
control with minimal excessive
light affecting the nighttime sky or
spilling over to adjacent properties.
Agencies can equitably engage
with underserved communities to
determine where and how new and
improved lighting can most benefit
the community by considering their
priorities, including eliminating crash
disparities, connecting to essential
neighborhood services, improving
active transportation routes, and
promoting personal safety.

Local Road
Safety Plans
A local road safety plan (LRSP) provides a framework for identifying, analyzing, and prioritizing roadway safety improvements on local roads.
The LRSP development process and content are tailored to local issues and needs. The process results in a prioritized list of issues, risks, actions, and improvements that can be used to reduce fatalities and serious injuries on local roads. FHWA has developed several resources including an LRSP Do- It-Yourself website which further explains the process and includes resources local agencies and their partners need to create and implement an LRSP.1 1 https://highways.dot.gov/safety/local-rural/local-road-safety-plans 2 Anderson et al. Noteworthy Practices: Addressing Safety on Locally-Owned and Maintained Roads A Domestic Scan, FHWA-SA-09-019, (2010). 3 Developing Safety Plans: A Manual for Local Rural Road Owners, FHWA-SA-12-017, provides guidance on developing an LRSP.
Approximately 75 percent of rural
roads are owned by local agencies.2
While local roads are less traveled
than State highways, they have a
much higher rate of fatal and serious
injury crashes.2 Developing an LRSP is
an effective strategy to improve
local road safety for all road users
and support the goals of a State’s
overall Strategic Highway Safety Plan
(SHSP).
Although the development process
and resulting plan can vary
depending on the local agency’s
needs, available resources, and
targeted crash types, aspects
common to LRSPs include:
• Stakeholder engagement
representing the 4E’s:
engineering,
enforcement,
education, and
emergency
medical services.
• Collaboration
among
municipal,
county, Tribal,
State, and/or
Federal entities
to leverage
expertise and
resources.
• Identification of target crash types
and crash risk with corresponding
recommended proven safety
countermeasures.
• Timeline and goals for
implementation and evaluation.
Local road agencies should consider
developing an LRSP to be used as a
tool for reducing roadway fatalities,
injuries, and crashes.3 LRSPs can
help agencies create a prioritized
list of improvements. LRSPs are
also a proactive risk management
technique to demonstrate an
agency’s responsiveness. The
plan should be viewed as a living
document that can be updated to

Road Safety Audit
While most transportation agencies have established traditional safety review procedures, a road safety audit (RSA) or assessment is unique. RSAs are performed by a multidisciplinary team independent of the project. RSAs consider all road users, account for human factors and road user capabilities, are documented in a formal report, and require a formal response from the road owner. (See the eight steps for conducting an RSA below.) RSAs provide the following
benefits:
• Reduced number and severity of
crashes due to safer designs.
• Reduced costs resulting from early
identification and mitigation of
safety issues before projects are
built.
• Increased opportunities to
integrate multimodal safety
strategies and proven safety
countermeasures.
• Expanded ability to consider
human factors in all facets of
design.
• Increased communication and
collaboration among safety
stakeholders.
• Objective review by independent
multidisciplinary team.
RSAs can be performed in any
phase of project development,
from planning through construction.
Agencies may focus RSAs
specifically on motorized vehicles,
pedestrians, bicyclists, motorcyclists,
or a combination of these roadway
users. Agencies are encouraged
to conduct an RSA at the earliest
stage possible, as all roadway design
options and alternatives are being
explored.

Speeding vehicles, poor visibility for pedestrians, blind curve in crosswalk and for cars turning left onto Solano Way from Hilltop Rd. In 2025 the STOP sign on Hillcrest at this corner of concern was actually run down by speeding vehicle.
Location needs Stop light or STOP signs / Speedbumps for BOTH directions.
Drivers are just heading into and out of town in this area making this strip of Solano Way a very dangerous raceway for drivers and pedestrians. I have personally witnessed many near misses of pedestrians in the crosswalk in the past 5 years in particular.
I have also been the victim of a head on collision in this very same area in 2020. The perpetrator was speeding into the area, lost control and crossed the center divide and collided with our vehicle just past the same Hilltop Rd/Solano Way location. Our car was totaled. I was 17 days post a major abdominal cancer surgery. My hospital bill was $58,000. The guilty driver had minimum insurance coverage.
My husband and I have lived on Hilltop Rd for 40 years and we have witnessed many many dangerous incidents at this location.
Though there is now a “Slow Down” sign past the crosswalk, it is only on one side of the rode. This is sorely inadequate and needs to be updated to a fulll STOP sign or traffic light AND/ or speed bumps on BOTH directions of Crosswalk.
Your attention and funding of this project is badly needed BEFORE someone is killed, not afterward.

My wife and I have lived on Navaronne Way in Concord for over 40 years.
During this time, we have routinely hiked the paths/walkways from Concord to Walnut Creek. During the Pandemic, the paths/walkways were overtaken by Mountain Bikers flying down the hills. Now, young kids have taken over the paths/walkways on Electronic Bikes, flying down the paths/walkways at high rates of speed, with the only indication they are coming from behind you is from the loud sound of the knobby tires against the payment. Numerous times they have flown by us walking on the trails, barely dodging/missing us.
Furthermore, over time it appears as if the paths/walkways have become a throughway for kids commuting back and forth to school and/or friends' houses, as we see the same kids in the same areas constantly. Adults, 16 years of age and older, are required to have an operator's license to operate a motorized vehicle(car/motorcycle) on the streets, be it an internal combustion gas vehicle or an Electronic Vehicle. However, on the paths/walkways, kids with no instruction/operators' licenses, are flying at high rates of speed on Electronic Bikes, as if it were an open roadway for vehicles.
On numerous occasions I have seen people and/or their pets nearly struck by kids on Electronic Bikes and/or kids on the side of the pathways injured from wrecks. In conclusion, it is my belief that the pathways/trails in the Open Spaces are intended for people to walk and/or people to ride conventional bicycles and not have the pathways/trails overrun, by unlicensed kids on motorized vehicles.

In conclusion, it is my belief that the pathways/trails in the Open Spaces are intended for people to walk and/or people to ride conventional bicycles and not have the pathways/trails overrun, by unlicensed kids on motorized vehicles.

Please extend the PH bike lane that ends at CCC all the way along Willow Pass. This area near the mall and 680 is deadly for anyone who's not in a car (and dangerous for car drivers as well).
i see people riding bicycles on the sidewalk here everyday. They should have their own safe lane to travel in the roadway.

The intersection at concord blvd and denkinger is a hot spot for car accidents and a disaster waiting to happen. My family lives in the neighbor hood on the north side of this intersection (on denkinger where it dead ends). Whenever we leave our neighborhood (heading south on denkinger) we almost get a hit by oncoming traffic heading north on denkinger and turning west on concord blvd. Straight has the right of way yet people constantly turn in front of us and my family personally has come very close to be in an accident. There are signs saying left turn needs to yield yet people never do!! This light should be changed to flashing yellow left turn signal from denkinger (heading north) to concord blvd (heading west). This needs to be addressed before something serious happens. I have witnessed accidents myself and like I said have nearly been in accidents with my whole family in the car. My wife has reported the same thing to me while she’s driving our kids! It’s a simple fix that the city should implement to protect people obeying the law. This needs to be addressed if concord is serious about drivers safety! I have even seen a concord police officer not yielding to oncoming traffic at this intersection! Please do something to fix this hot spot

The traffic near Willow Pass and Galindo is nasty much of the time and especially betwen 4 and 6 p.m. with cars blocking traffic because of the timing of the traffic lights. The City of Concord has gone overboard with traffic lights of obnoxiously long cycles so that we often wait for a green light even when there are no other cars. Other cities uses 4-way stop signs . Whenever the lights temporarily stop functioning, drivers take turns and get through intersections safely and faster. I walk and also ride my bicycle and find the cycles to be crummy for them, too. I am sorry we can't do better. I'd love to get a response about this. [email protected]

When turning left from Victory Lane onto Brookview Circle (coming from Monument Boulevard), it is difficult to see oncoming traffic from the opposite direction of Victory Lane. The problem is worsened by cars often parked on the right side of that curve, which block the view for drivers attempting the left turn.

I make a right turn from pine holloe on to comino solano. First you force all traffic into the left lane and then there is a right turning lane. People stay in the right lane and run right into the right turning lane. Those trying to follow the rules are in danger of being hit. It would be safer to just turn the right lane into a right turn only lane and not force us left and then right to make the turn.

There is lots of car traffic in the morning and afternoon during pick up and drop off.
Many parents have complained and witness several close calls with students crossing and cars going too fast. We have 2 crosswalks but neither have cross walk guards. The lights on the ground are tempermental and don’t go off when someone is crossing and also have gone off in the evening when no one is crossing.

First, the 4 way intersection at the corner of Sunshine Dr. and Detroit Ave in front of the "Meadow Homes Park" sign needs to be turned into a traffic light.
This area is so heavily populated with children and pedestrians and I've witnessed countless people and children walking across the street to and from the park or school who have almost gotten hit by drivers running the stop signs all around, or not noticing people walking across the street. This area needs to have walking signals for pedestrians and a light that forces cars to stop or go that is metered. I've also personally experienced almost getting hit a few times walking a stroller with my child in it or walking my dog and it's starting to get out of hand. The park itself is wonderful, but also problematic for children and families most of the time. There are so many people sleeping in their cars around the park, doing drugs, drinking excessively and publicly during school hours while children at Meadow Homes School are present or playing outside. Additionally, people illegally park all up and down the streets surrounding the park, most notably on Sunshine Dr, Detroit Ave, and in all the cul de sacs surrounding Meadow Homes park. They illegally park inside cul de sacs during the week, (Charles Court, Haven Court, etc.) every weekend and most days during the week. We've had issues of people parking illegally inside the cul de sac during medical emergencies where abulances or firetrucks can't get through. Hit and runs of parked cars along Sunshine Drive happens constantly, during the day and during the night time. There aren't enough streetlights, or brighter streetlights on Sunshine Dr, so when people are driving drunk it's dark and they end up smashing into cars that are parked along the sides of homes. This area is also always scattered with broken and smashed alcohol bottles. Overall, this area has such high traffic of families, children and pedestrians and it 's just not safe and progressively gets worse I

This intersection has been a problem since we have moved in 6 years ago. I have seen many accidents and have almost been apart of them multiple times. For some reason people coming from Deckenger and turning left towards concord HS forget that they need to give on coming traffic (from the neighborhood ex Yeoman/ Deckenger drive) the right away. I have almost been hit several times leaving our neighborhood but now always have to proceed with caution. I have seen pedestrians also almost hit by turning cars.
There are several signs posted but that has done nothing. I think something as simple as a flashing yellow left hand signal would change this problem. Also, there are lots of cars driving on Concord BLVD that run yellow and red lights at this intersection. Is there something that can be done to lengthen the time a light turns red to green to prevent accidents? Thank you!

Is there something that can be done to lengthen the time a light turns red to green to prevent accidents? Thank you!

Vehicles entering Estates Drive do not know that the street is technically a dead end after crossing the Highland Drive intersection. It would help if the city install a “not a through street” sign before the intersection so people are aware of this.

I find the intersection of Estates Drive and Overhill road to be dangerous. Cars turning from estates cannot see incoming traffic. I was hoping that the city can install mirrors to help gauge overhill before committing to the turn.

The traffic light changes on Monument Blvd. have made for an absolutely ridiculous time to get from the freeway to Reganti Dr. Today it was 35 min at 3pm! Now people seem to love to gas it after they have passed Victory Ln. due to frustration. Removing the no turn on red at Reganti Dr recently has also made many pedestrians almost get hit. It will be happening soon enough.
Reganti Dr itself is in terrible condition. I would say it needs to be resurfaced with a higher weight limit or something since all the big rigs, fire trucks and large work vehicles go to El Molino and destroy the road with their weight.
There is always a yellow box truck on the corner of Reganti Dr. and Peach Pl. that covers the stop sign, especially on the weekends. I have seen many people not stop since they don’t see it as well as almost hit pedestrians since it makes it a blind corner.

Every single day hundreds if not thousands of drivers illegally make a U-Turn here at this light at panoramic drive during commute hours. If they don't do the U-Turn at the light they will turn on Panoramic and make an illegal turn at the first left which clearly states no u-turns. Super annoying and unsafe as a person who crosses this street every day!

A favorite dead end for racers to do donuts. Look no further than the street to see rubber evidence of unlimited donuts. Multiple vehicles all times of the day. Mostly a black Nissan 350Z and an older silver Mustang with a black stripe on the hood. More patrols in this area and enforcement of parking laws would help. Many vehicles double parked, on the sidewalk, on private property, leaking fluids into the gutter from the nearby auto body shop.

Constant street racers between Detroit and Cowell on Monument. Cars, motorcycles, especially evenings and weekends. I don't understand how they can race so close to the PD and not get noticed, pulled over and cited or towed. I've seen them race past a marked police unit and nothing was done.
There's already been a couple of bad accidents and a rollover at the curve near the cemetery, and trees never grow up very large between Systron and Cowell in the median because they're constantly being wiped out. Large trees in this median would protect opposing traffic from a head-on, but the trees never last that long. It's a matter of time before pedestrians are hit and killed in this vicinity or a gruesome head-on takes place.

We have noticed lately that there has been quite a few accidents on Birch Ave. between Hickory and Fairfield. There is a dip on Birch Ave and Upland Dr and the cars don’t slow down and they speed up trying to avoid it. On the same spot there have been some cars doing donuts. As a matter of fact there was a big accident on the streets mentioned above on 3/14/26. We have seen an increase of traffic in a couple of years because people are trying to make a short cut because the heavy traffic on the freeway. On these streets there are a lot of potholes, these streets have not been paved in a long, long time. On the corner of 2297 Upland Dr and Birch Ave when it rains it collects a big puddle of water and the drainage is on the other side of the street and this is because the street hasn’t been paved for a long time. I got some pictures in case are needed. Thanking you in advance

Traffic light needs to be adjusted at Cowell and Babel. Frequently there is a long line of traffic on Cowell, but light is red d/t sensing of car turning left from Babel to Cowell. Onse the traffic on Cowell gets the green light, it once again turns red as soon as the Babel light senses another car needing to turn left onto Cowell. Sometimes, only 3 cars get to progress down Cowell after the green light only for the light to turn red once again. This leads to a long line at this intersection on Cowell street.

Before we dive into the data.
A short overview of what a Comprehensive Safety Action Plan is — and why Concord is adopting one tonight.
W H A T I T I S
A plan for safer
streets.
A federally-recognized roadmap that
identifies where serious crashes happen
in Concord, why they happen, and the
proven measures that prevent them —
built around the U.S. DOT Safe System
framework.
W H Y W E ’ R E H E R E
It unlocks federal
funding.
Adoption is the federal prerequisite to
apply for the U.S. DOT Safe Streets and
Roads for All program — including the
$15–20M implementation grant due May
26 — plus several state and regional
safety programs.
H O W I T ’ S B U I L T
Data + community
voice.
Five years of Concord-specific crash data,
651 community survey responses, 77
interactive map comments, and alignment
with 14 existing City and regional plans
inform every recommendation.
Tonight, you’ll hear how each of these elements comes together to make Concord safer.

Re: Letter of Support — White Pony Express, Bay REPAIR Local Community Benefits Fund (Seed Grant)
Dear Members of the Bay REPAIR Review Committee,
On behalf of the City of Concord Council, I strongly support White Pony Express (WPE) and their application for a Bay REPAIR Seed Grant. As Mayor of Concord, California, I have seen firsthand what this organization has built — and I am confident that WPE represents exactly the kind of community- led, results-driven work this fund was designed to support.
The Bay REPAIR program was created to direct penalty funds back into the communities that have borne the heaviest air quality burdens. Most of the nonprofits served by WPE are located in these areas.
This grant would allow them to sustain and expand their efforts.
WPE's food recovery model is an emissions reduction strategy. Every day, their volunteer-powered program rescues approximately 12,500 pounds of fresh food from over 100 local food donors — food that would otherwise decompose in landfills and generate methane and CO₂. The numbers are significant: WPE eliminates over 8,035 metric tons of CO₂-equivalent emissions annually. This is not a secondary benefit of their work. It is central to it.
WPE is a proven SB 1383 implementation partner. They have created a certified food recovery pathway for local businesses that did not previously exist — reducing organic waste diversion at the source while connecting surplus food to people who need it. Their track record as a multi-year recipient of the Keller Canyon Mitigation Fund reflects consistent recognition of this environmental impact by local funders.
Today, WPE delivers fresh, healthy food to a total of 56 nonprofit recipients located in communities identified to receive support with this funding— with a waitlist of 22 organizations in these areas alone waiting for free weekly food deliveries. The demand is real, and the capacity to meet it is within reach.
Bay REPAIR Seed Grant funding would allow WPE to expand daily food rescue operations into these underserved corridors, covering the fuel and fleet costs that currently limit their reach. More rescues mean more food diverted from landfills, more methane kept out of the atmosphere, and more healthy food reaching families who face both hunger and the health consequences of living in communities with compromised air quality.
These are not separate problems. WPE treats them as one.
7.a
I fully and enthusiastically endorse White Pony Express's application for Bay REPAIR Seed Grant funding. They have earned this community's trust over more than a decade of service, and they are ready to put these resources to meaningful, measurable use.
Please feel free to contact my office with questions.
Sincerely,
Laura M. Nakamura
