1 To: Palo Alto City Council
From: Rail Safety Ad Hoc Committee
Date: April 15, 2026
Re: Churchill Avenue Rail Crossing: Integrated Policy Analysis and Decision Framework
This memo is the Rail Safety ad hoc committee’s report to the Council which supplements the Staff Report. The Staff Report provides the technical detail on closure impacts, mitigation options, and regulatory requirements. This memo draws on that analysis, the prior XCAP and consultant work, and the JED Foundation’s and CDC’s guidance to offer the Council the policy choices and tradeoffs among the alternatives presented with the goal of informing the public and supporting the Council in well- informed decision-making.
I. The Decision Context
The Council is considering whether to temporarily close the Churchill Ave rail crossing as a lethal-means restriction strategy following recent youth suicides with up to three potential goals; 1) an attempt to break the recent track suicide cluster; 2) reduce daily trauma at Paly from train horn noise; 3) conduct a trial closure to inform what long-term impacts and mitigations may be required for permanent closure.
Not a Choice Between Action and Inaction
The City has already taken significant steps: in part in response to a student-led petition signed by 3700 community members, 24/7 security guards were added at all four at-grade crossings starting February 23, 2026 with costs shared by PAUSD, engagement of the JED Foundation for a community-wide youth mental health and suicide prevention evaluation, and support for Caltrain’s intrusion-prevention and detection work. The question before the Council is which actions best advance safety across the rail corridor and throughout the community, and what are the trade-offs and costs of different actions.
Multiple Goals Are in Play—and They Point to Different Interventions The Staff Report identifies three goals that a closure might serve. The Council’s decision will be clearer if it identifies which goal is primary:
Goal How closure addresses it Alternative approaches
Restrict access to a
known high-risk location
in an attempt to break the
current suicide cluster
systemwide
Temporary physical barrier
eliminates access at Churchill.
Addresses one location; JED
Foundation notes access points
remain across the broader corridor.
24/7 security guards (already in
place); enhanced fencing and
intrusion deterrents. JED
Foundation engagement; a full
range of expanded school and
community-based mental health
services and supports
Reduce daily trauma at
Paly from train horn noise
Temporary closure would eliminate
train horns near campus.
Quiet Zone implementation
(planned FY27 eliminates horn use
without closing the crossing.
A trial closure to gather
real-world data to inform
a permanent closure
decision
A trial closure would provide traffic
and pedestrian behavior data.
Requires extensive planning,
monitoring, and success criteria.
Subsequent permanent closure
would likely require extensive
physical mitigation measures
preceding permanent closure at
high expense over many years.
Traffic modeling tools (such as
Streetlight Data, Replica) may
provide some data and simulation
modeling without a physical closure.
2 II. Policy Tradeoffs
The following tradeoffs reflect considerations the Committee believes are material to the options before the Council. Each has arguments on both sides; the Committee presents them for the Council’s weighing rather than to recommend a direction.
1. Lethal Means Restriction at One Location vs. System-Wide Risk The case for closure draws on public health evidence that reducing access to a known high-risk location can prevent impulsive acts and disrupt a suicide cluster. The Staff Report frames the closure in these terms, and the principle is supported by the JED Foundation, the 2016 CDC Epi-Aid report, and other experts.
At the same time, access to the Caltrain corridor remains available in the community at Meadow, Charleston, Palo Alto Ave, nearby stations, and other points along the line. The JED Foundation letter in the Staff Report (Attachment B) notes that structural interventions at specific crossings are “unlikely to address suicide by train across the broader peninsula, given the many accessible points along the rail corridor.” Given that Meadow and Charleston have historically been the dominant locations of Palo Alto track suicides, the degree to which a Churchill closure reduces system-wide risk—versus relocating it—is unclear and a concern.
2. Guards Already in Place
The Staff Report notes that 24/7 security guards have been in place at all four crossings since February 23, 2026. Critically, during the 2010–2017 period no fatalities occurred while Trackwatch or security guards were present, indicating that monitoring is an effective intervention although no approach is viewed as failsafe. A key question is what additional benefit physical closure provides above active monitoring, and whether that incremental benefit is sufficient to justify the risks, transferred impacts, and costs described in the Staff Report?
3. Transportation and Pedestrian Safety Tradeoffs and Costs The Staff Report and prior XCAP analysis provide substantial detail on the transportation consequences of closure. The Council should weigh these against the safety and trauma-reduction rationales for closure.
Projections are that closure would divert more than 8,000 daily vehicle trips from Churchill, pushing six nearby intersections to Level of Service F—meaning jammed conditions with average peak delays of 50 to 80 seconds per vehicle. The six intersections are Alma/Lincoln, Alma/Embarcadero, Alma/Kingsley, El Camino Real/Embarcadero, El Camino Real/Oregon Expressway, and Alma/Oregon Expressway.
School bus operations (26 buses, 52 daily trips) would require rerouting with potential effects on PAUSD schedules, business impacts to Town and Country Shopping Center and others, and special-event access to Stanford Stadium would be significantly constrained.
Public safety responder impacts to Fire, Police, and ambulance emergency access to Stanford Hospital (affecting the mortality and morbidity rates of ER patients) are broader corridor-congestion concerns, particularly on Embarcadero and Oregon Expressway as primary routes to Stanford Hospital and to major commercial districts. The greater impacts are the delays due to traffic congestion more than the additional travel distance to the nearest crossing.
Supporters of closure assert that traffic impacts are a temporary inconvenience and that travel patterns adjust over time. They also note that the current crossing itself creates ongoing risk, both from the proximity of lethal means and from existing traffic and safety hazards at the intersection, and that some degree of disruption is a reasonable price for the protection closure would provide.
3 The consultant analysis by AECOM and Hexagon, conducted for the XCAP process in YEAR, evaluated closure only as part of a required parallel infrastructure package, never as a standalone action without substantial mitigation investments (XCAP Report, Section 4.1.1, pp. 23–24). That package comprises ten specific mitigations:
• Reconstruction and widening of the Alma Street overpass over Embarcadero Road • New bike/pedestrian overcrossing at Embarcadero Road and Alma Street • Right-turn lane addition from eastbound Embarcadero Road to Kingsley Avenue • Left-turn lane addition from southbound Alma Street to Kingsley Avenue • New traffic signals on the Alma overpass at the Embarcadero slip road and at Kingsley Avenue • New signal at the Embarcadero Road/Kingsley Avenue/High Street intersection • Bicycle and pedestrian improvements along the Embarcadero/High Street corridor • Signal timing optimization and additional turn lanes at El Camino Real/Embarcadero Road • Signalization of Alma Street on/off ramps at Oregon Expressway • Turn capacity improvements and signal optimization at Oregon Expressway/El Camino Real
In addition, XCAP recommended additional measures likely needed (XCAP Report, Section 4.6.1, p. 69):
• A new bike/pedestrian crossing at Seale Avenue (to be built before any grade separations, to provide safe passage for bikes/pedestrians during construction) • Redesign of the Lincoln/Kingsley/High Street intersection to manage traffic spillover • Further improvements along the Embarcadero/High/Emerson corridor • Resolution of student pick-up/drop-off conflicts along the Embarcadero slip road
XCAP also noted that some network-wide congestion effects were not fully modeled, suggesting actual impacts may be understated.
Central to the closure concept as evaluated by the XCAP process is a grade-separated bicycle and pedestrian undercrossing beneath both the rail line and Alma Street—providing cyclists and pedestrians a safe direct crossing. Without it, displaced students and cyclists would rely on three alternatives:
• Embarcadero Road: not currently recommended by the City’s Safe Routes to School program due to high-speed slip lanes and poor pedestrian yielding.
• The north side of Embarcadero is anticipated to receive a significant addition of Paly biking traffic between Emerson and the underpass. This is the same location where additional northbound vehicles on Alma will take Lincoln to Emerson as an informal cloverleaf to reach westbound Embarcadero.
• The most direct route for cyclists heading to Paly from Old Palo Alto and beyond would be the south-side sidewalk, mixing bikes and pedestrians along a busy arterial at peak commute times. A new, high volume of Eastbound bikes are likely to turn onto Emerson from the sidewalk to the street at the same location that new additional vehicles will turn onto Emerson, and adjacent to the new Castilleja parking garage exit.
• California Avenue Tunnel: is very narrow to accommodate bikes and other pedestrians, and its grade exceeds the 8% ADA standard (12%), causing cyclists to accelerate on descent. Additional demand would concentrate more users, including e-bikes and scooters, in an already constrained space.
•
• Homer Tunnel: adds considerable pedestrian distance, depending on the point of origin, making it unlikely for significant use as an alternative route.
Closure advocates argue that the Staff Report’s near-term Embarcadero improvements and enhanced wayfinding, combined with community adaptation over time, would make alternative routes workable, and 4 that a trial period would generate the data needed to assess actual conditions. Those who raise concerns about a closure argue that the specific constraints of available detour routes—and the time period required for traffic and behavioral patterns to stabilize—mean significant safety consequences for students and the general public would likely occur. The degree to which near-term mitigation steps address impacts is a key question. The Staff report also points out that a secondary effect of increased walk/bike time would result in more people driving, creating an absolute increase in car trips that will have a net negative for transportation safety.
4. “Temporary” vs. the Reality of Reopening
The Staff Report describes a 6–12 month closure, which the California Public Utilities Commission (CPUC) would classify as temporary. However, the staff report informs us that the Federal Railroad Administration (FRA) does not have a “temporary” classification and may log the crossing as permanently closed. Reopening would require a new CPUC diagnostic review, redesign, and construction at uncertain costs and timeline. The Staff Report acknowledges this uncertainty.
The Council should be clear about whether it would make this decision as potentially a permanent closure, even if labeled temporary. That framing would affect how the Council weighs the costs of the mitigation package eventually required as well as the implications for the Quiet Zone project currently planned for construction in the fall of FY27.
5. Trauma Reduction: Closure vs. Quiet Zone
An argument for closure is the current psychological “triggering” impact on students, staff, parents, and the broader community” from frequent train horns sounding near Paly.
The Quiet Zone project, if accelerated, would permanently eliminate routine train horn use at Churchill without closing the crossing. A temporary closure would eliminate horn noise for ~six months beginning in the fall of 2026, but may delay the implementation of a permanent Quiet Zone due to FRA regulations. .
6. Equity Across the Community
The Staff Report focuses on Churchill. However, the historical record of incidents along the Palo Alto rail corridor identifies Meadow/Charleston as the predominant location of track suicides. A closure decision that concentrates resources at Churchill invites the question of what are risk-based and equitable actions across the corridor. If fencing, Caltrain anti-intrusion technologies, and guards are adequate security measures at the other crossings, are they adequate at Churchill? If not, why not?
III. Options: Pros, Cons, and Open Questions
For full technical detail on each option, see Staff Report Analysis and Staff Report Attachment A. The Committee’s assessment of the key considerations for each is:
Option A: Proceed with Temporary Closure (6–12 months)
Considerations in favor
• Provides physical, 24/7 access restriction—the
most direct form of lethal-means reduction at this
location
• Specialists in suicide prevention cite the 12
months following a youth suicide as the critical
postvention window; a closure beginning late
summer 2026 would cover the period through
spring of 2027, aligning with that window
• Eliminates triggering effect of train horn near
Paly during the second half of the one-year
postvention window
Considerations against
• Cannot be implemented immediately: closure
requires Caltrain coordination and CPUC
diagnostic meeting, design, regulatory approval,
and construction. Staff estimates the earliest
feasible implementation is late summer 2026
• The most acute period in response to the current
cluster—the spring semester and end of school
year—will have passed before physical closure
and cessation of horns is in place; guards are the
primary available intervention during this period
5 • Provides a visible community commitment to
taking the strongest action
• Could generate real-world traffic data to inform
permanent closure planning
• Direct closure cost estimated at ~$1.2M
(preliminary; includes fencing, signal changes,
detour signage, staff/consultant services, Caltrain
coordination, and data collection)
• Fire Department modeling shows only a ~15-
second average increase in first-arriving unit
response times for incidents near the closure—
assessed by staff as operationally manageable
• Transportation and pedestrian safety impacts
are significant and will occur before identified
mitigation infrastructure is in place
• Pedestrian access to the corridor at other
locations is not eliminated; system-wide
prevention benefit is uncertain
• If closure becomes permanent, Embarcadero
mitigation costs may displace the need for some
elements of the long-term grade separation
program
• FRA would potentially classify the crossing as
permanently closed; reopening process may be
uncertain and costly
• Temporary closure would delay or complicate
the Churchill Quiet Zone (currently planned for
FY27)
• Embarcadero Road improvements
recommended before closure are estimated at
$1.5–$2M (full two-phase project: ~$2.9M); and
not yet in the Capital Improvement Program
• Full long-term mitigation package identified by
XCAP (required if closure becomes permanent)
exceeds $100M and would take as much as a
decade to implement
• Corridor congestion on Embarcadero Road and
Oregon Expressway, the primary Police and Fire
routes to Stanford Hospital, Stanford and Town &
Country Shopping Centers, and major commercial
districts, could reduce routing flexibility and
increase response times, particularly for multi-unit
incidents, special events, and peak-hour calls
• Ambulance transport routes remain available but
travel times would become longer. The
Embarcadero and Oregon underpasses already
present limited overtaking ability for emergency
vehicles due to lane configuration and concrete
barriers
Option B: Maintain Crossing with Enhanced Measures
Continue 24/7 monitoring; accelerate Quiet Zone implementation; advance JED Foundation recommendations; continue Caltrain intrusion-prevention work.
Considerations in favor
• Guards are active at all four crossings as of
February 23, 2026—the primary measure that
provides immediate cluster-interruption capability
during the most acute phase of the postvention
window
• Guards have a documented track record of
effectiveness at monitored locations
• No additional transportation or pedestrian safety
costs
• Quiet Zone acceleration can address long term
trauma-reduction and environmental health goals
at lower cost and disruption
• JED Foundation recommended tools available
for near term earlier implementation consistent
Considerations against
• Physical access to the crossing remains; guards
and other measures are not failsafe
• May be perceived as insufficient action given
community expectations
• Current guard contract costs ~$1.7M/year (split
equally with PAUSD; ~$850K City share);
sustaining this beyond the one-year contract
requires a funding commitment
• Quiet Zone timeline (FY27 design, FY28
construction) means the primary trauma-reduction
benefit is roughly 18 months away even if work
begins immediately
6 with the 2016 CDC Epi-Aid report multi-layered,
corridor-wide approach
• Avoids the ~$1.2M direct closure cost and the
$1.5–$2M in Embarcadero improvements
required before temporary closure could proceed
• Preserves Measure K funding and FY27 timeline
for Churchill Quiet Zone
• No impact on Fire, Police, or ambulance
response times—Embarcadero and Oregon
Expressway remain unaffected as emergency
response corridors
Option C: Trial Closure with Pre-Defined Evaluation Criteria Proceed with closure as a time-limited trial, with explicitly defined metrics for success and failure established before the closure begins.
Considerations in favor
• Provides same near-term benefits as Option A
while framing the decision as data-driven and
revisable
• If implemented late summer 2026 as estimated,
a trial running through spring of 2027 would cover
the latter portion of the 12-month postvention
window experts identify as critical
• Structured evaluation framework supports
accountability and community trust
• Real-world traffic and behavioral data would be
more reliable than modeling alone, although not
able to identify impacts from future traffic growth
• The ~$1.2M direct closure cost covers the full
trial period including data collection and
reopening; no additional trial-specific cost beyond
Option A
• Fire Department’s modeled ~15-second first-
response delay near the closure is assessed as
manageable; the trial period would generate real
data on whether broader corridor impacts
materialize as projected
Considerations against
• Like Option A, cannot be implemented until late
summer 2026 at the earliest; the spring 2026
semester, historically a high-risk period, passes
before closure is in place
• Carries the same transportation and safety
negative impacts as Option A during the trial
period, including the $1.5–$2M Embarcadero
improvement requirement
• FRA permanence issue applies regardless of
trial framing. Reopening costs and process
remain uncertain
• Meaningful only if criteria are genuinely binding;
reopening against community pressure could be
difficult in practice
• If the trial leads to permanent closure, the full
$100M+ mitigation package would eventually be
required
• Same emergency response risks as Option A
apply during the trial: corridor congestion on
Embarcadero and Oregon Expressway could
increase Police, Fire, and ambulance response
times, and the Embarcadero underpass’s physical
constraints limit emergency vehicles’ ability to
bypass congestion
Option D: Phased Approach—Maintain Current Measures, Define Conditions for Future Closure
Continue current measures while advancing mitigation infrastructure and setting defined thresholds that would trigger a closure decision.
Considerations in favor
• Allows XCAP/consultant-identified mitigation
infrastructure to advance before closure, reducing
public safety risk
• Guards are already active and providing cluster-
interruption capability during the current high-risk
period; this option preserves that protection while
building toward safer closure conditions
Considerations against
• Does not provide the immediate complete
physical access restriction at Churchill that
supporters of closure are seeking
• May be seen as deferring action during a period
of acute community need; by the time mitigation
infrastructure is ready, the current cluster’s 12-
month postvention window will have passed
7 • Preserves Quiet Zone timeline and avoids FRA
permanence complication
• Near-term costs are limited to ongoing guard
contract (~$850K/year City share) and
Embarcadero pedestrian safety improvements
(~$2.9M, already recommended and partially
budgeted regardless of closure)
• No near-term impact on emergency response:
Embarcadero and Oregon Expressway remain
available as unrestricted Police, Fire, and
ambulance corridors until and unless closure
proceeds
• Guard contract costs continue to accrue
(~$850K/year City share) with no defined
endpoint; sustained PAUSD cost-sharing is not
guaranteed beyond the current term
• Full XCAP mitigation package (>$100M)
required before closure can be safely
implemented; infrastructure timelines are long and
funding is not identified
• If closure is eventually triggered under this
option, the same emergency response risks
identified under Options A and C would apply at
that time
IV. Questions the Committee Recommends the Council Address Questions Answered by the Staff Report
1. What is the primary goal or goals of closure? The closure is a lethal-means reduction strategy during a suicide cluster, intended to break contagion patterns by restricting access to a known high-risk location. The Council should confirm this framing reflects its intent or identify if an additional goal—such as trauma reduction or infrastructure evaluation—is equally part of the consideration.
2. What evaluation criteria exist for a closure? Preliminary measures are identified including Fire and Police response performance, intersection delays, traffic volumes, pedestrian and bicycle impacts, public feedback, and track-intrusion compliance. A December 2026 check-in is proposed, with the option to terminate early. The Staff Report does not establish specific thresholds that would trigger termination versus continuation. The Council should identify those thresholds before authorizing closure.
3. What is the plan for Meadow and Charleston if closure proceeds? Prioritizing Quiet Zones at Meadow and Charleston during a Churchill closure is recommended to advance those projects while the Churchill Quiet Zone would be delayed. The Council should consider what investments are warranted at those crossings.
Questions Not Answered by the Staff Report
4. What does the recent guard deployment record show? The Staff Report notes the historical effectiveness of guards but does not provide data on interventions or incidents at Churchill since guards were deployed.
5. What is the historical distribution of incidents by crossing and school affiliation? The Staff Report states that most recent fatalities occurred at Churchill but that other locations have been involved over the years. Meadow/Charleston have had the highest proportion of fatalities. What is the data?
6. Could the Quiet Zone be accelerated as an alternative to closure for trauma reduction? The Staff Report gives the current Quiet Zone accelerated timeline (design fall 2026, construction fall 2027 with Measure K funding) and notes closure would delay it.
V. Potential Actions Regardless of Closure Decision
• Commit to funding for 24/7 guard staffing beyond the current one-year contract, including continued PAUSD cost-sharing
• Accelerate JED Foundation engagement and begin implementing available tools and recommendations consistent with the 2016 CDC Epi-Aid report while waiting for the full findings report (expected summer 2026)
• Advance Embarcadero Road pedestrian and bicycle safety improvements 8 • Continue Caltrain partnership on intrusion detection, enhanced fencing, and anti-trespass measures at all crossings
• Develop a corridor-wide safety investment plan that addresses Meadow and Charleston proportionally due to their historical incident rates
