City Council Staff Report
Report Type: Consent Calendar Meeting Date: 4/26/2021
City of Palo Alto Page 1
Council Priority: Grade Separations
Summary Title: Approval of Amendment # 3 to Contract C18171057 with
AECOM
Title: Approval of Amendment No. 3 to Contract C18171057 with AECOM for
continued services for the Connecting Palo Alto Rail Grade Separation (PL -
17001) effort and to increase compensation by $80,000 for a total not -to-
exceed amount of $2,874,658
From: City Manager
Lead Department: Transportation Department
Recommendation
Staff recommends that the City Council approve and authorize the City Manager or his designee
to execute Amendment No. 3 to Contract C18171057 with AECOM for continued services for
the Railroad Grade Separation and Safety Improvements Capital Improvement Project (CIP PL-
17001) effort and to increase compensation by $80,000 for a total not-to-exceed amount of
$2,874,658.
Background
The City Council approved a contract with AECOM to serve as the primary consultant for the
Connecting Palo Alto rail grade separation project on April 16, 2018. The approved contract
(C18171057), for $1,278,660, is shown with the staff report (CMR 9100).
In addition, City Council also authorized Amendment No. 1 on June 24, 2019 (CMR 10463) and
Amendment No. 2 on June 23, 2020 (CMR 11273) to the AECOM contract. These contract
amendments provided for additional services supporting rail grade separation projec t outreach
efforts and providing assistance to City for technical support for review of the selected rail
grade separation alternatives by the Expanded Community Advisory Panel (XCAP). The
proposed contract amendment is attached to this report as Attachment A.
Discussion
The consultant contract and additional services include the following tasks. These have been
completed to provide for the technical support and completion of technical studies for the
City of Palo Alto Page 2
review of the alternatives in consideration for Grade Separations along the Caltrain corridor at
Churchill Avenue, Meadow Drive, and Charleston Avenue crossings by the XCAP. The project
study report will be completed as part of the next step of the process as the Council reviews the
XCAP recommendations and provides direction in furthering the development of these
alternatives.
• Project Management – until December 2020 providing general project management
tasks required for managing all aspects of the planning effort (administration,
coordination, and quality control). This task also accounts for meetings with outside
agencies relevant to the project (e.g., Caltrain).
• Community Engagement – the virtual Town Hall meeting and platform, 3-D
renderings/photo simulations and 360-degree color 3-D animated videos of the
alternatives and the 11x17 informational fact sheets for all nine (9) alternatives.
• Conceptual Plan Development - Preliminary civil engineering was conducted to help the
XCAP and the City Council review the proposed alternatives.
• Traffic engineering at Churchill, Meadow and Charleston:
o Draft and final traffic memoranda
• Preliminary construction cost estimates
With the onset of COVID19, the XCAP deliberation process was delayed beyond the expected
completion date. This resulted in additional meetings and support from the Consultant. In
addition, the Consultant conducted the noise and vibration analysis and prepared the report to
support the XCAP review of various alternatives. AECOM also reduced their fees for the most
recent contract amendment, in light of the fiscal challenges caused by COVID19.
The XCAP has now completed its review and provided the final report to the City Council (CMR
11797). With the completion and delivery of the XCAP report, Staff anticipated the need for
additional support from the consultant to support the Grade Separation workplan for review of
the proposed alternatives. Based on the grade separation workplan proposed to the City
Council tonight (CMR 12185), Staff anticipates the services of the consultant to provide for such
support at three to four additional City Council meetings.
Therefore, Staff requested AECOM to provide the proposal for ongoing meeting support on a
time and material basis for “not to exceed” cost per meeting including support from
subconsultants as needed at these meetings. This amendment provides for additional AECOM
and Sub Consultants support for up to four (4) meetings on time and material basis to the
existing AECOM Contract for Rail Grade Separation Project.
Timeline
At the direction of the City Council's on the rail grade separation work plan, staff will coordinate
with the Consultant to provide technical and professional assistance needed to support Council
meeting discussions for decision making on alternative selection for rail grade separation at the
Churchill Avenue, Meadow Drive, and Charleston Road Crossings along Caltrain corridor.
City of Palo Alto Page 3
Resource Impact
Funding required for Contract Amendment 3 is available in the FY 2021 Adopted Capital Budget
in the Railroad Grade Separation and Safety Improvement project, PL-17001. The existing
AECOM Contract including Amendment 1 and Amendment 2 is in th e amount of $2,794,658.
Based on the amount of the Contract Amendment No. 3 of $80,000, the total contract amount
for the AECOM Contract will be increased to $2,874,658. It is important to note that this
amendment only provides funding for additional meeting support and does not presume or
allow for additional work beyond the current recommended path forward. Should the City
Council choose to adjust current direction or add additional scope and work, staff will need to
assess needs and return to the City Council with additional amendments to this contract.
Funding for future fiscal years is subject to City Council approval through the annual budget
process.
Stakeholder Engagement
Since June 2019, the XCAP has been conducting regular meetings for the review of the various
alternatives in consideration at the Churchill Avenue, Meadow Drive , and Charleston Road
crossings along the Caltrain corridor. Staff in coordination with AECOM consultants provided
continuous support to the XCAP and conducted other community engagement activities. In
addition to the XCAP, to further engage the community, as part of the project, City hosted a
Virtual Town Hall from August 19, 2020 to September 14, 2020 gaining over 1,000 unique
visitors to the online platform. This virtual platform was designed to inform the community and
seek feedback on the proposed alternatives for the grade at the three separation grade crossing
locations.
A summary report of the virtual Town Hall was provided as an informational report to the City
Council on November 30, 2020. Earlier in 2020, before the pandemic began, the City also
hosted two well attended Rail Town Hall meetings and smaller neighborhood specific open
house meetings to gain community input on the rail alternatives and answer community
questions. Staff also developed and released online surveys and used social media, the City’s
website and electronic newsletters to, inform, answer questions and gain feedback from the
community on this important City priority.
Policy Implications
Goals and policies from the Palo Alto 2030 Comprehensive Plan that are supported and
advanced by the proposed project include:
Goal T-1 Create a sustainable transportation system, complemented by a mix of land
uses, that emphasizes walking, bicycling, use of public transportation and other
methods to reduce GHG emissions and the use of single-occupancy motor
vehicles.
City of Palo Alto Page 4
Policy T-1.19 Provide facilities that encourage and support bicycling and walking.
Policy T-1.10 Support Caltrain modernization and electrification capacity and service
enhancements and extension to Downtown San Francisco.
Policy T-1.25 Pursue transportation funding opportunities for ongoing transportation
improvements that will help mitigate the impacts of future development
and protect residents’ quality of life. When other sources are unavailable,
continue to fund improvements, operations and maintenance through
the general fund.
GOAL T-2 Decrease delay, congestion and VMT with a priority on our worst intersections
and our peak commute times, including school traffic.
Policy T-2.3 Use motor vehicle LOS at signalized intersections to evaluate the
potential impact of proposed projects, including contributions to
cumulative congestion. Use signal warrants and other metrics to evaluate
impacts at unsignalized intersections.
Goal T-3 Maintain an efficient roadway network for all users.
Policy T-3.5 When constructing or modifying roadways, plan for use of the roadway
by all users.
Policy T-3.6 Consider pedestrians, bicyclists, e-bikes and motorcycles when designing
road surfaces, curbs, crossings, signage, landscaping and sight lines.
Policy T-3.14 Continue to prioritize the safety of school children in street modification
projects that affect school travel routes, including during construction.
GOAL T-6 Provide a safe environment for motorists, pedestrians and bicyclists on Palo Alto
streets
Policy T-6.1 Continue to make safety the first priority of citywide transportation
planning. Prioritize pedestrian, bicycle and automobile safety over motor
vehicle level of service at intersections and motor vehicle parking.
Policy T-6.3 Continue to work with Caltrain to increase safety at train crossings,
including improving gate technology and signal coordination.
Goal T-8 Influence the shape and implementation of regional transportation policies and
technologies to reduce traffic congestion and GHG emissions.
Environmental Review
The recommendation in this report does not constitute a project in accordance with the
California Environmental Quality Act and is therefore not subject to environmental review.

CITY OF PALO ALTO OFFICE OF THE CITY ATTORNEY
April 26, 2021
The Honorable City Council
Palo Alto, California
Council Approval of Appointment of Terence Howzell as Chief
Assistant Attorney
Recommendation
The City Attorney recommends that the Council approve the appointment of
Terence J. Howzell to the position of Chief Assistant City Attorney.
Background
The City Attorney makes appointments to positions in the City Attorney’s Office.
The City
Attorney’s appointment to the Chief Assistant position is subject to approval
of the Council. (Municipal Code section 2.08.120(4).)
The Chief Assistant City Attorney position (formerly called “Principal
Attorney”) was approved by the City Council in Fiscal Year 2015. The position
strengthens strategic legal services with respect to both transactional/
counseling and litigation functions. The Chief Assistant manages the day-to-day
operations of the City Attorney’s Office, supports legal team members,
advises key departments with respect to complex and high-risk matters, and
manages the City’s litigation portfolio. The Chief Assistant supports the City
Manager and the Council on selected matters.
Discussion
The City Attorney requests approval of the appointment of Terence J. Howzell to
the position of Chief Assistant City Attorney.
Mr. Howzell has been practicing law for 33 years, including serving in Palo Alto
from November 2015 through January 2021 in the same role of Chief
Assistant City Attorney. Prior to representing Palo Alto, Mr. Howzell spent 18
years in the San Francisco City Attorney’s Office, where he has served in
increasingly senior positions in the areas of employment law, labor relations,
public contracting and general advice matters. He has litigated numerous
disputes in state and federal courts and before a variety of administrative
agencies. Mr. Howzell has served as a team leader with a track record of
mentoring and supporting attorneys. He earned his Juris Doctor from the
University of California, Berkeley, and holds a Bachelor of Arts in English
Literature from Dartmouth College.
Page 2
Mr. Howzell will begin work on April 26, 2021.
Resource Impact
Mr. Howzell will be an at-will employee serving at the pleasure of the City
Attorney. His annual salary will be $254,405, which is within the Council-
approved range for the position, subject to a 13 day reduction in FY 21
ending June 30, 2021, as provided in the FY 2021 Cover Letter to the
Compensation Plan for Management and Professional Personnel, pro-rated
for the period of service. Benefits will be as provided in the Council-
approved Compensation Plan for Management and Professional Personnel.
These costs can be met within the City Attorney’s Office’s FY 21 budget and
are also consistent with planning scenarios departments have been asked
to prepare for consideration for the FY 22 budget. Two senior-level
attorney positions – the Chief Assistant and one Assistant City Attorney
position – have been vacant for four months and six months, respectively,
straining the ability of the City Attorney’s Office to timely meet the legal
services needs of all City departments and officials in an increasingly-
complex environment. Filling one of the two vacant positions will reduce the
use of outside counsel to supplement in-house attorney resources.
Policy Implications
This appointment is consistent with existing City policies.
Environmental Review
Approval of the appointment is not a project subject to environmental review.

Summary Title: PUBLIC HEARING: TEFRA Hearing Oshman Family JCC
Title: TEFRA HEARING Regarding Conduit Financing for the Oshman Family
Jewish Community Center Located at 3921 Fabian Way, Palo Alto, and
Approving the Issuance of Revenue Obligations by the Ca lifornia Enterprise
Development Authority for the Purpose of Financing and Refinancing the
Cost of the Acquisition, Development, Construction, Installation, Equipping
and Furnishing of Various Educational Facilities and Other Matters Relating
Thereto
From: City Manager
Lead Department: Administrative Services
Recommendation
Staff recommends that Council:
1) Conduct a public hearing under the requirements of the Tax Equity and
Fiscal Responsibility Act of 1983 (TEFRA) and the Internal Revenue Code
of 1986, as amended; and
2) Adopt a Resolution (Attachment A) approving the deemed reissuance of
obligations by the California Enterprise Development Authority (CEDA) for
the benefit of Oshman Family Jewish Community Center (Borrower).
Background
Borrower is a California nonprofit public benefit corporation and an organization
described in Section 501(c)(3) of the Internal Revenue Code of 1986 (the “Code”), has
requested that CEDA participate in the reissuance (for federal income tax purposes) of
one or more series of revenue obligations in an aggregate principal amount not to
exceed $37,800,000 (the “Obligations”), for the purpose of the deemed refinancing of
the acquisition, construction, improvements, furnishing and equipping by the Borrower
of a 142,000-square-foot community center. The center includes a cultural arts hall, a
pre-school, meeting rooms, classrooms, indoor and outdoor pools, a fitness center
including a gymnasium, a teen center, a café, a playground and playing field, and
regional offices, all located at 3921 Fabian Way, Palo Alto, California 94303
(collectively, the “Project”). The Project is and will be owned by Borrower.
For the Obligations to qualify as tax-exempt obligations, the City of Palo Alto must
City of Palo Alto Page 2
conduct a public hearing (TEFRA Hearing), providing the members of the community an
opportunity to speak in favor of or against the use of tax -exempt obligations for the
refinancing of the Project. Prior to the hearing, reasonable notice must be provided to
the members of the community. Following the close of the TEFRA Hearing, an
“applicable elected representative” of the governmental unit hosting the Project must
provide its approval of the deemed reissuance of the Obligations for the refinancing of
the Project.
Discussion
The Borrower originally financed the costs of the Project through a conduit financing
with CEDA in March 2013. Since the Project is located within the jurisdiction of the City
of Palo Alto, the City conducted a TEFRA Hearing and adopted a resolution that
approved the issuance of obligations by CEDA for the benefit of Borrower on January
14, 2013 (CMR 3416).
The terms of the 2013 CEDA financing are being amended such that federal tax laws
deem the transaction to be a “reissuance” of the 2013 debt for federal income tax
purposes. This is not a new borrowing or a new project, but rather is a tax law
characterization of an amendment transaction, which nonetheless requires TEFRA
approval again.
A TEFRA Hearing is simply an opportunity for all interested persons to speak or to
submit written comments concerning the proposal to issue the debt and the nature or
location of the facility to be financed; however, there is no formal obligation on the part
of Borrower or Council to respond to any specific comments made during the hearing or
submitted in writing.
CEDA is a joint exercise of powers authority of which the City became a member on
January 14, 2013. The Joint Exercise of Powers Agreement provides that CEDA is a
public entity, separate and apart from each member executing such agreement. The
debts, liabilities, and obligations of the CEDA do not constitute debts, liabilities or
obligations of the members executing such agreement. The Obligations to be deemed
reissued by CEDA for the Project will be the sole responsibility of Borrower, and the City
of Palo Alto will have no financial, legal, moral obligation, liability or responsibility for the
Project or the repayment of the Obligations for the refinancing of the Project. All
financing documents with respect to the deemed reissuance of the Obligations will
contain clear disclaimers that the Obligations are to be paid for solely from funds
provided by Borrower.
The City is in no way exposed to any financial liability by reason of its membership in
CEDA. In addition, participation by the City in CEDA does not impact the City’s
appropriations limits and will not constitute any type of indebtedness by the City.
Outside of holding the TEFRA Hearing and adopting the required resolution, no other
participation or activity of the City or Council with respect to the deemed reissuance of
the Obligations will be required. Based on the benefits of the Project to the Palo Alto
community and the lack of any financial obligations on the part of the City, staff
recommends that Council approve the attached Resolution.
City of Palo Alto Page 3
Resource Impact
As stated, the City will incur no financial obligation from approval of the
recommendations. The City will receive a fee for its services when the Obligations are
deemed reissued.
Policy Implications
Actions recommended in this report are consistent with Council’s prior actions in
supporting non-profit financings under the TEFRA (e.g., recently approving tax-exempt
financing through the California Municipal Finance Authority for Palo Alto Housing
Corporation (CMR: 10976).)
Stakeholder Engagement
City staff has coordinated with representatives of the Oshman Family Jewish
Community Center to prepare for the TEFRA hearing.
Environmental Review
Action on this item does not constitute a project under Section 21065 of the Public
Resources Code.

City of Palo Alto Page 1
Council Priority: Grade Separations
Summary Title: XCAP Final Report and Recommendations
Title: Connecting Palo Alto Rail Grade Separation: Discuss Final Report and
Recommendations From the Expanded Community Advisory Panel (XCAP),
Removal of two Rail Grad e Separation Alternatives From Further
Consideration, and Review of the Draft Work Plan (Continued From March
23, 2021)
From: City Manager
Lead Department: Transportation Department
Recommended Motion
Staff recommends that the City Council:
1. Discuss the final report prepared by the Expanded Community Advisory Panel (XCAP)
(Attachment A) including their findings and recommendations on the Connecting Palo
Alto rail grade crossings at Churchill Avenue, Meadow Drive, and Charleston Road along
the Caltrain corridor;
2. Based on the XCAP recommendations, consider eliminating the following options from
further consideration:
a. South Palo Alto Tunnel (Passenger and Freight)
b. South Palo Alto Tunnel (With At-Grade Freight)
3. Review and discuss the Grade Separation Work Plan on Remaining Alternatives (as
provided in the Final Report) under Council consideration for decision-making and
additional direction to staff.
City of Palo Alto Page 2
Background
On April 22, 2019, City Council approved the structure and membership of an Expanded
Community Working Group for the evaluation of the Connecting Palo Alto railroad grade
separation at crossings along the Caltrain corridor. Thus, the Expanded Community Advisory
Panel (XCAP) was formed in June 2019. Later in September 2019, City Council provided
additional direction and changed the responsibilities of the XCAP, including adding additional
responsibilities, expectations, and members. The City Council set a deadline of April 30, 2020
for the XCAP to evaluate the seven alternatives under consideration for grade separation on
three grade crossings; Churchill Avenue, Charleston Road, and Meadow Drive. At that time, the
City had begun the next phase in the project’s timeline: Community Conversations. This phase
lead to a series of community engagement opportunities ranging from in-person to online.
In an update to the City Council on January 21, 2020, the XCAP presented three (3) new
community-driven ideas for consideration. These community-generated ideas were reviewed
by the XCAP and volunteer retired civil engineers before coming to the City Council. The City
Council directed staff to move forward with exploring two (2) of the three (3) new ideas
presented by the XCAP. Staff and AECOM in coordination with XCAP Technical Working
Subgroup refined these ideas and developed the conceptual plans at a similar level to the
existing seven (7) alternatives.
The final nine (9) alternatives reviewed by XCAP at these grade crossings are as follows:
Churchill Avenue
Churchill Avenue Closure with Mitigation - Option 1 & 2
Churchill Avenue Viaduct
Churchill Partial Underpass
Meadow Drive and Charleston Road
Meadow Charleston Trench
Meadow Charleston Viaduct
Meadow Charleston Hybrid
Meadow Charleston Underpass
South Palo Alto Tunnel (Passenger & Freight)
South Palo Alto Tunnel (With At-Grade Freight)
Since that time, the XCAP has completed its deliberations and prepared a final report providing
their recommendations to the Council. (See links to the final report and its appendix at the end
of this staff report.) This agenda item brings forward for City Council consideration, the current
status of the Connecting Palo Alto railroad grade separation project and the final report and
recommendations prepared by the XCAP for evaluation of grade separation alternatives.
City of Palo Alto Page 3
Discussion
Since September 2019, the XCAP members met regularly to review the details and evaluate the
rail grade separation alternatives at Churchill Avenue, Meadow Drive, and Charleston Road
crossing. During the review process, the XCAP provided updates to the City Council on regular
basis. Consultants and staff continued to support the XCAP and conducted studies, performed
analysis, and provided additional technical information for the review of the alternatives.
Removal of Two Rail Grade Separation Alternatives
With the completion of the XCAP final report (links to the XCAP Final Report and Appendix
provided at the end of the report) providing recommendations to the Council, the study session
on March 23, 2021 was held. At this study session, Council received the final XCAP report, staff
provided an overview of the alternatives in consideration and the XCAP discussed major
recommendations and findings.
Considering the environmental challenges and the estimated costs for the South Palo Alto
Tunnel Alternatives, the XCAP unanimously recommended to remove the tunnel alternatives
from further consideration. Based on the unanimous decision of the XCAP, staff recommends
that the City Council eliminate from further consideration both the South Palo Alto Tunnel
Alternatives that is 1) With Passenger and Freight and 2) With Freight at Grade.
Additional details on these major recommendations and findings of the XCAP are as follows:
Churchill Avenue:
• Six of nine members voted to support the closure of Churchill Ave Crossing
▪ In a follow-on motion by a vote of 7-0-2 additional mitigations and studies
for the Churchill Closure alternative were recommended beyond what was
proposed by the consultants.
▪ In a second follow-on motion, the same seven supported Option 2 of the
bike/pedestrian tunnel (tunnel in the middle of Churchill) for the Closure
with Mitigations alternative with further study of improvements.
Charleston Road and Meadow Drive:
• XCAP unanimously removed from consideration the two short tunnel alternatives for
South Palo Alto due to high cost and significant environmental concerns related to
the potential water table and creek impacts.
• Of the remaining alternatives, XCAP unanimously voted they could not decide with
the current information available.
For the South Palo Alto Tunnel alternatives, the railroad tracks are to be lowered in a trench
south of Oregon Expressway to approximately Loma Verde Avenue. To provide for the tunnel,
34 feet twin-bore tunnel for South Palo Tunnel (Passenger and Freight) alternative and 30 feet
twin-bore tunnel for South Palo Alto Tunnel (With At-Grade Freight) alternative will be
required. These tunnels begin near Loma Verde Avenue and extend to just south of Charleston
City of Palo Alto Page 4
Road. The railroad tracks will then be raised from south of Charleston Road in trench to
approximately Ferne Avenue. The new electrified southbound railroad tracks are proposed to
be built at the same horizontal location as the existing railroad track. However, the northbound
track will need to be moved to the east within the limits of the tunnel to accommodate the
spacing required between the twin bores.
For South Palo Alto Tunnel (Passenger and Freight) Alternative, the railroad tracks will carry
both passenger and freight trains as it does today. However, with the South Palo Alto Tunnel
(With At-Grade Freight) Alternative, the tunnel will carry only passenger trains and the freight
trains will remain at grade.
The estimated costs associated with these alternatives well exceed one billion dollars. Also, the
lowering of the tracks will require the diversion of Adobe and Matadero creeks, resulting in the
need for lift stations/siphons and numerous regulatory agencies ’ permits/approvals.
Negotiations with the regulatory agencies will be lengthy and difficult since there are other
“least impacting” alternatives that could be considered. In addition, pump stations will also be
needed for dewatering since the tunnel will be below the groundwater level. The pump
stations, lift stations, and/or siphons will have increased long-term ongoing maintenance costs
and risk of flooding. These alternatives will also require major utility relocations to construct
the lowered railroad.
Grade Separation Work Plan on Remaining Alternatives
Staff has developed the following draft work plan for an in-depth review of the remaining
alternatives under consideration for further City Council action.
City Council Consideration in Summer:
• Charleston/Meadow detailed review of alternatives in consideration
• Charleston/Meadow direction on additional studies/next phase of the project
City Council Consideration in Fall:
• Churchill detailed review of alternatives in consideration
• Churchill direction on additional studies/next phase of the project
City Council Reconvene the Rail Committee in Fall/Winter:
• Discuss financial considerations
The following graphic illustrates where we are in th e project development process, and some of
the critical phases/steps remaining leading to actual construction. Key considerations as the
City Council deliberates on the next steps are that: (a) the costs involved in further engineering
analyses increase significantly going forward; (b) further studying multiple alternatives in
greater detail will involve significantly greater expenses; and, (c) formal approval from
responsible agencies (including Caltrain, VTA, and potentially Valley Water, the County of Santa
City of Palo Alto Page 5
Clara, and others) will occur much later in the development process and after additional
expense.
Upon the Council’s review and direction at the subsequent discussions and action items
through the work plan, staff will develop alternatives for further review and selection of
preferred alternatives at each of the crossings and prepare the City's final project report. The
development of alternatives, additional studies, and support during the work plan will require
professional consultant support and therefore will require amendment(s) for the additional
scope to perform this work. Based on direction from the City Council, staff will return for
Council adoption of amendments to the existing consultant contracts and expanded scope of
work needed to accomplish additional work. As noted in previous reports, the full funding for
the entire project including design and construction is yet to be fully established.
Potential Next Steps
Following the City Council's review of alternatives and consideration of the XCAP
recommendations and the final report, staff is seeking feedback on proposed next steps in
moving the project forward, including the work plan noted above. While these are options for
Council to consider, it is important to note that some of these next steps may have cost
implications, either financially due to costs associated with additional studies or costs as a
result of carrying forward multiple options before decision making.
Potential Options for further input could include:
• Review and select a final alternative at each of the crossing locations based on the
significant work completed to date.
City of Palo Alto Page 6
• Invite regional partners like Caltrain and Valley Transportation Agency (VTA) to discuss
City Council’s concerns and questions.
• Further narrow the number of alternatives under consideration and seek additional
studies based on Council direction.
• Perform additional studies of selected alternatives as directed at each of the locations
and bring back additional information for Council consideration.
• Direct staff to prepare the initial Project Study Report (PSR) that provides the summary
of actions and demonstrates the purpose, need, and provides the scope of the project
which is necessary to complete studies and the work needed for project approval and
environmental design.
The selection of preferred alternatives will therefore lead to the development of preliminary
engineering and preparation of environmental documents including associated Environmental
Impact Report (EIR). The completion of Environmental documents will better position the City
to seek grant funding from Federal and State programs for such projects. Depending upon the
timing and funding availability, after the approval of EIR, the project will move towards
completion of final design documents and then followed by construction of project
improvements.
As demonstrated in the rail grade separation design and approval process figure above, the
project is in the initial stages of defining project scope as we are working towards the selection
of preferred alternatives at the subject crossings. Any additional studies that provide support to
select the preferred alternative will help develop the draft PSR. The purpose of using the PSR
document is to gain approval for the project studies to move into the Project Approval and
Environmental Document (PA&ED) phase. The refined concept project plans through
preliminary engineering are also developed concurrent ly. The development of concept plans,
environmental documents, and draft PSR helps in developing project estimates, program the
capital outlay support cost needed for various phases of the project, identify and secure
funding needed for the project. These documents further assist in gaining approvals from
various regulatory agencies and develop cooperative agreements for the final design including
preparation of final Plans, Specifications and Cost Estimates (PS&E). With the approval of final
PS&E, the project moves toward construction of improvements.
Resource Impact
The recommendations in this report to discuss the XCAP final report, eliminate South Palo Alto
Tunnel options from consideration, and review and discuss the draft grade separation work
plan do not result in direct resource impact. Funding for currently planned work on grade
separation alternatives evaluation is programmed in the FY 2021 Adopted Capital Budget in
project PL-17001, Railroad Grade Separation. Funding for future years is subject to City Council
approval through the annual budget process. Direction from the City Council regarding further
work on the grade separation projects may lead to future resource impacts. As City Council
direction is provided, corresponding budget adjustments will be brought forward for approval
City of Palo Alto Page 7
as appropriate. This project is historically funded by the General Capital Improvement Fund
through funding sources such as SB1 and Measure B funding in certain instances when
available, or through General Fund support.
Environmental Review
The proposed action is part of a planning study for a possible future action, which has not been
approved, adopted, or funded and is therefore exempt from the California Environmental
Quality Act (CEQA) in accordance with CEQA Guidelines Section 15262. The future decision to
approve construction of any one of the identified potential alternatives would be subject to
CEQA and require preparation of an environmental analysis. Environmental review and design
for the grade separation project will be performed in the subsequent steps of the project
development.

Letter of Transmittal
Dear Mayor DuBois, Vice-Mayor Burt, and Members of the City Council:
We are pleased to present to you our report on potential grade separations for the train crossings at
Churchill, Meadow, and Charleston. Our committee held 47 meetings from June 2019 through
February 2021 for a total of approximately 1500 volunteer hours. In addition, we individually spent
many hours outside the meetings on matters such as reviewing consultant reports, meeting with
volunteer professional advisors, and preparing this report. We recognize that grade separations are
a multi-year project and have prepared our report in a manner so that we hope it will be useful to
you in 2021 and also for decision-makers many years in the future.
Sincerely,
Expanded Community Advisory Panel:

Executive Summary

XCAP Executive Summary
Background
The Need
Palo Alto at-grade crossings have become increasingly congested and dangerous and the planned
increases in trains following completion of Caltrain’s electrification project will make grade
separations essential to prevent near-gridlock at those crossings and adjacent intersections. High-
Speed Rail (HSR) continues to plan to eventually make it to the Peninsula as part of a “blended
system” with Caltrain which would result in even more trains on the rail corridor, further
exacerbating the need for separations.
Initial Steps
In 2017, the City of Palo Alto initiated a grade-separation planning process that was led by Staff and
consultants, with public input coming through Community Meetings. In 2018, City Council concerns
led the former City Manager to change consultants and create a Citizen Advisory Panel (CAP). The
role of the CAP was limited to advising staff and consultants on improving community outreach and
communications. It had no role in analyzing or advising grade separation alternatives.
XCAP
In order to have stronger stakeholder and community involvement, the City Council in June 2019,
created the Expanded Community Advisory Panel (XCAP) and in October 2019, authorized XCAP
to set its agendas, elect a Chair and Vice Chair and recommend grade separation design
alternatives to the City Council. There were initially fourteen XCAP members: eight community
representatives carried over from the CAP, along with six additional representatives. The six
additional members included a former Mayor with experience in high-speed rail policy issues, the
President of the Palo Alto Chamber of Commerce, a representative from Friends of Caltrain, an
employee designated by Palo Alto Unified School District (PAUSD), a member of the Planning and
Transportation Commission, and a resident from the Charleston/Meadows neighborhood. During
the XCAP process PAUSD and the Chamber of Commerce decided that it was not appropriate to
have their representatives participate. In addition, the Friends of Caltrain representative and two of
the community members, for personal reasons, also resigned. This report reflects the
recommendations of the nine remaining members.
XCAP proceeded rapidly to define its processes, identify and fill information gaps, invite proposals
from the public, explore a broader set of alternatives, and narrow options. XCAP established a goal
of making unanimous recommendations and required a two-thirds vote to make a recommendation
to the City Council. The final recommendations in this report are not unanimous, but there is
unanimity on the removal of some alternatives from further consideration and on further work that
needs to be done.
Executive Summary
v
Impacts of the COVID Emergency
The global pandemic has impacted the XCAP process. It caused a hiatus in meetings scheduled
for March. Under the City’s new Zoom protocols, however, XCAP has met nearly weekly since
April 2020, to the conclusion of XCAP’s work in January 2021.
Due to fully online meetings, XCAP members reported difficulty having important communication
with neighborhood groups, residents, or even XCAP meeting attendees who, after a live XCAP
meeting, would typically linger with XCAP members and Staff to better understand and discuss the
issues. The crisis also made it difficult to get the community’s attention on this important issue as
people have been, understandably, focusing on health, safety and living through the pandemic
restrictions. In addition, the sudden collapse of City revenue caused by the pandemic meant that
any further contract amendments for the consultants or additional costs were unlikely, impacting
XCAP’s ability to do any further iterations on the newest, community generated concepts which
some XCAP members thought desirable.
Engagement with key stakeholder groups has also suffered. The Palo Alto Unified School District
had to focus on providing critical educational adjustments rather than on this and other non-
emergency issues. Similarly, coordination with the bicycle community, the business community and
other stakeholder groups suffered as a result of the pandemic.
The pandemic has also impacted the ability for the City to conduct traditional Town Hall meetings,
although the staff and consultants were eventually able to move online to a Virtual Town Hall.
It was held over the summer for four weeks (Aug 19 - Sept 14) and engaged a higher number of
residents than is typical for an in-person Town Hall (over 1000 unique users), allowing a wider
audience flexibility to review the materials and information at their convenience. However, it is
difficult to determine whether this platform was an effective way to clearly communicate and have
discourse about the trade-offs of the various alternatives.
The dramatic drop in ridership of public transit, the fiscal crisis across multiple transit and
government agencies due to the pandemic and the unknowns resulting from the Presidential
election and now the change in administrations has resulted in a high level of uncertainty, leading to
further difficulty in making firm decisions. XCAP remains convinced that while the timeframe for the
need for grade separations will likely be pushed out by a few years, the importance of these
projects necessitates continuous work and focus so Palo Alto can be ready to complete these
projects as funding becomes available.
Findings Overview
Constraints
XCAP was tasked with recommending grade separations for Churchill Avenue, Meadow Drive, and
Charleston Road. The Council’s decision to remove Palo Alto Avenue from XCAP’s purview and
instead include it as part of an eventual Downtown Coordinated Area Plan led to a disjointed
analysis of North Palo Alto. With only seven places citywide for vehicles to cross the tracks
(Palo Alto Avenue, University Avenue, Embarcadero Road, Churchill Avenue, Oregon Expressway/
Executive Summary
vi
Page Mill Road, Meadow Drive and Charleston Road), traffic analysis shows that modifications at
one crossing will likely impact the other crossings.
In 2012, Caltrain and High-Speed Rail signed a Memorandum of Understanding (MOU) that
indicated the need for two additional “passing” tracks somewhere within northern Santa Clara
County so HSR trains can pass Caltrain trains. The need for passing tracks is currently in dispute
between Caltrain and HSR and is being partially addressed through HSR’s Environmental Impact
Report for San Francisco to San Jose. Additional technical studies between Caltrain and HSR are
needed to determine the location of the passing tracks. Caltrain can operate at their maximum
projected capacity under their most recent business plan without needing any additional tracks if
HSR does not share the corridor. There is uncertainty if HSR will get to the Peninsula but passing
tracks must be kept in mind.
Initially, Caltrain had indicated HSR passing tracks would likely be located somewhere between
South Palo Alto (south of Oregon Expressway) and northern Mountain View. During the XCAP
process, and in the absence of a resolution of this issue with HSR, the Caltrain Joint Powers Board
adopted a very conservative Rail Corridor Use Policy essentially preserving the possibility of
needing two additional tracks the entire length of the City of Palo Alto. Caltrain has indicated that if
Palo Alto wants to move forward with designs prior to an HSR/Caltrain decision on the passing
track location, the City will need to show that designs do not preclude the possibility of a future four
track system.
Notably, all of the designs XCAP reviewed assume a two-track system and the impacts of a four-
track system on designs were not addressed since Caltrain’s policy decision was not shared with
XCAP until April 2020. If four tracks are needed, a significant revised XCAP-type study would
have to be undertaken.
Decisions and Recommendations
Churchill Avenue
At Churchill Avenue, XCAP started with two alternatives: A Viaduct or a Churchill closure with
mitigations suggested by the traffic consultants including two options for a bike/pedestrian tunnel
at Churchill. A third, community generated alternative, known as the Partial Underpass, would
depress Churchill on the west side of the tracks, allowing cars to turn north/south onto Alma but
they could no longer cross Alma. From the east side of Alma, traffic traveling westbound towards
Alma could only turn right to head north on Alma.
Ultimately, six of nine members voted to support the closure of Churchill. The remaining three said
they could not support the recommendation without further study.
In a follow-on motion by a vote of 7-0-2 additional mitigations and studies for the Churchill Closure
alternative were recommended beyond what was proposed by the consultants.
Executive Summary
vii
In a second follow-on motion, the same seven supported Option 2 of the bike/pedestrian tunnel
(tunnel in the middle of Churchill) for the Closure with Mitigations alternative with further study of
improvements, while the other two members abstained.
For both follow-on motions, one member abstaining did not support the Closure and therefore did
not vote on the follow-on motions and the other abstaining member thought all bike designs needed
to be re-conceptualized because both designs were unacceptable as they force bikes/pedestrians
into tunnels.
Meadow Drive and Charleston Road
For Meadow Drive and Charleston Road, XCAP originally considered a viaduct, a hybrid (raised
berm), a trench, a short tunnel with freight and a short tunnel with freight at the surface. In
addition, an underpass alternative was developed by a community member and refined by the
City’s consultant which would leave the tracks at their current elevation and have bikes and
pedestrians in dedicated tunnels that separate them from both the train and Alma.
XCAP unanimously removed from consideration the two short tunnel alternatives for South Palo
Alto due to high cost and significant environmental concerns related to potential water table and
creek impacts.
Of the remaining alternatives, XCAP unanimously voted they could not decide with the current
information available. No alternative received the support of more than three members. The pros
and cons of each alternative are described in the body of this report. However, several broad
themes emerged in the deliberations:
1. Every alternative has negatives, there was no clear winner, and there was no enthusiasm
for any particular one.
2. While neighborhood opposition to the above ground solutions --the hybrid and the viaduct--
was vociferous and near unanimous, there was also recognition that the trench, tunnel, and
underpass have serious challenges.
3. Resolution of the four-track issue is essential.
The time delays occasioned by the pandemic may be fruitfully utilized by the City in further studies
and the implementation of small projects such as bike/pedestrian crossings that would mitigate or
even enhance whatever grade separation is ultimately chosen. The report has more detailed
findings, suggested future areas of study and additional recommendations within the report and
provides a summary with additional Lessons Learned in Chapter 7. Among the things the City
needs to work on in the near term include:
1. Groundwater analysis and geotechnical studies.
2. Prioritize participation in the Caltrain Corridor-wide Grade Separation Study.
3. Development of a formal structure to work with PAUSD and Bicycle advocacy groups on
soliciting detailed feedback.
Executive Summary
viii
4. Bike/Pedestrian-specific review of the impact of grade separations on bike/pedestrian
circulation.
5. Study bike/pedestrian crossings at Seale/Alma and vicinity of Loma Verde/Alma/Matadero
Creek.
6. Negotiate with Caltrain and High-Speed Rail regarding the possibility of passing tracks in
Palo Alto and their implications on design, cost, and timeline.
7. Create a framework for soliciting feedback from key stakeholders post-pandemic including
businesses and Stanford.
XCAP was asked not to focus on how to finance these projects and has not, but the panel did
occasionally receive information of how projects have historically been funded and what new
funding sources may emerge.
The completion of grade separations in Palo Alto is arguably the most expensive, complex, and
important transportation infrastructure investment the City will make in the next half century. The
work XCAP has completed to date has significantly improved the understanding of the City’s needs.
The City has been able to capitalize on new technology throughout this process to better
understand the transportation network, the relationship of key roads in the network to the existing
grade crossings and to each other. In addition, technology has helped improve outreach efforts and
XCAP’s deliberations have broadened the community’s understanding of the need for grade
separations and the challenges with the different alternatives. The ongoing flow of additional
information will enable improved designs as the City moves to the next phase. And while the
pandemic has pushed out the timeframe, the City can make productive use of the additional time by
preparing for these transformative changes in the City.
Note for the Reader: Colloquially, Palo Altans refer to Caltrain as traveling North/South. Similarly,
Alma Street is considered to run North/South where Old Palo Alto and Professorville are considered
East of Alma and Palo Alto High School, Southgate and Evergreen Park are considered West of
Alma. When looking at a map, however, Caltrain and Alma generally run from Northwest to
Southeast. All references to North, South, East and West in this report refer to the colloquial
direction, and all images created by the consultants have an arrow in the lower right corner showing
true North.

At-grade Crossing (also known as Level Crossing) - is an intersection where a railway line
crosses a road at the same level, as opposed to the railway line crossing over or under a road using
an overpass or tunnel.
Berm - Like an embankment, it is a long artificial mound of earth and stone built to support a road
or railway.
Blended System - Plan developed by Caltrain and California High-Speed Rail Authority to share
the existing train tracks between San Francisco and San Jose to support operations of High-Speed
Rail on existing Caltrain tracks, with some passing tracks where needed, to maintain operation of
both services.
California High-Speed Rail (CAHSR or HSR) - a project to bring high speed train
service from San Francisco to Los Angeles using the Caltrain corridor between San Jose and
San Francisco.
California Public Utilities Committee (CPUC) - State agency that regulates passenger and freight
rail operations in California. Also regulates electric, natural gas, telecommunications, water, rail
transit, and passenger transportation companies.
Caltrain - Operating agency that provides train service along a 77-mile route to 32 stations between
San Francisco and Gilroy.
Caltrain Business Plan (Long Range Service Vision) - A plan by Caltrain to define and assess
its service vision after completion of the electrification of its line and how that service vision can be
implemented and funded.
Catenary Wires - A system of overhead wires used to deliver electric power to electrified transit
vehicles or locomotives (also known as Overhead Contact System (OCS).
Crossover - Switches and track connections which allow trains to cross from one track to another
or a level crossing between two rail lines without connections.
dBA - Refers to noise levels measured in decibels using an “A-weighted” sound level (expressed in
units of dBA) The A-weighting network approximates the frequency response of the average young
ear when listening to most ordinary sounds. For more information, see pg. 7 of Appendix B-4-1
Noise and Vibration Comparative Analysis Report.
Electric Multiple Unit (EMU) - self-propelled electric rail cars coupled together into one train and
controlled by one engineer. EMUs do not require a locomotive.
Glossary
xv
Electrification - The installation of an overhead wire (catenary) system to enable trains to run on
electric power. Caltrain is in the process of electrifying their right of way between San Francisco
and San Jose, to allow retirement of their passenger diesel locomotives. Another form of
electrification, not used by Caltrain, is third rail.
Embankment - An embankment (also known as a berm) is a long artificial mound of earth and
stone, built to support a road or railway.

standards used by railroads operating in the United States.
Gate Downtime - the period of time that a crossing gate at a grade crossing is in the down position
when it stops traffic to allow trains to cross a roadway or a pedestrian crossing.
Grade - refers to the rate of change in the rise or fall in elevation of a railroad track. A rise of one
foot in elevation in 100 feet of track is a 1% ascending grade. Similarly, a decrease of one foot in
elevation in 100 feet of track is a descending grade of 1%. Also see Vertical Curve.
Grade Crossing - see At-grade Crossing.
Grade Separation - The process of separating a rail line from a road, or another rail line, to
eliminate delays or disruptions to the flow of traffic on both rail and road. Separation is achieved by
building bridges over or tunnels under the crossing site and/or by raising or lowering the rail line
tracks, allowing roads and or railways and canals to pass another without interrupting the flow of
traffic.
Types of grade separation:
● Viaducts are elevated grade separations, where the train is completely elevated above the
roadway on a long bridge or series of bridges, usually supported by a series of arches or on
spans between tall towers.
● Hybrids are where the train is partially elevated on an earthen berm that forms a wall and
the road is sunken down in a shallow trench.
● Tunnels are where the train is completely submerged underground and not visible.
● Trenches are where the train is in an open ditch while cars travel flat across the ditch, are
below grade separations.
Hybrid - A type of grade separation where the train is partially elevated on an earthen berm that
forms a wall and the road is sunken down in a shallow trench.
HSR (or CAHSR) – High-Speed Rail
Level of Service (LOS) - Level of Service (LOS) is a quantitative standard used to determine how
well an intersection (signalized or unsignalized) or street segment (between signalized
intersections) is operating from a traveler's perspective. Typically, six levels of service are defined,
Glossary

locomotive. EMU cars also use a pantograph to make contact with an overhead power wire.
Means Restriction - Reducing a suicidal person’s accessibility to mechanisms that cause injuries
and fatalities, such as access to a train that is considered a lethal means for intentional harm.
Noise Parapet - A low protective wall, roughly six feet high, designed to redirect noise away from
structures along the rail right of way.
Overhead Contact System (OCS) - A system of overhead wires used to deliver electric power to
electrified transit vehicles or locomotives (also known as Catenary Wires).
Peak Period - The heaviest ridership periods which, for the Caltrain Corridor, is defined as 6-10 AM
in the morning and 3-7 PM in the evening. It can also refer to the heaviest traffic period, as in the
peak periods reported in the traffic study.
Peninsula Corridor Joint Power Board (PCJBP or JPB) - The government entity which manages
the Caltrain commuter rail line. The PCJBB consists of three representatives from each of the three
counties in which the Caltrain line provides service: San Francisco, San Mateo and Santa Clara.
Positive Train Control (PTC) - A form of collision avoidance that integrates command, control,
communication, and information systems for controlling train movements with safety, security,
precision, and efficiency.
Right-of-Way (ROW) - Any strip or area of land, including surface, overhead, or underground,
granted by a deed or easement, for construction or maintenance according to designated use.
Caltrain owns its own right-of-way from San Francisco to the Tamien Station in San Jose. A right-
of-way can also be a roadway, public footpath, as well as electrical transmission lines and sewer
lines.
Safe Routes to School (SRTS) - The Palo Alto Safe Routes to School program is a partnership
between the City, the Palo Alto Unified School District, and the Parent Teacher Association (PTA)
to reduce risk to students en route to and from school and to encourage more families to choose
healthy, active, sustainable alternatives to driving solo.
Shoofly - A temporary track built to bypass an obstruction or construction site. Caltrain shoofly
tracks will need to be electrified for Caltrain to maintain passenger train service during grade
separation construction.
Glossary

Sound Wall - A noise barrier (also called a sound wall, noise wall, sound berm, sound barrier,
noise parapet or acoustical barrier) exterior structure designed to protect from noise pollution.
Superelevation - The banking of railroad track on curves which allows the forces produced by the
weight of the train to counteract the outward forces of the speed of the train on the outside rail, thus
allowing higher speeds with greater safety margins.
Trackage Rights Agreement (TRA) - an arrangement where the company that owns the line
retains all rights but allows another company to operate over certain sections of its track. The
agreement may specify whether the latter company can serve customers on the line. The JPB has
a TRA with the Union Pacific railroad, which uses its right-of-way.
Train Preemption - (or signal preemption) Interruption of normal traffic flows on a road at a level
grade crossing to give priority to the safe passage of a train.
Trench - A type of grade separation where the train is in a below ground open concrete box with a
road above it remaining at its current level, crossing the trench on bridges.
Tunnel - A type of grade separation where the train is in an underground concrete tube deep
enough to pass under traffic bearing roads.

1. Introduction
1.1. Connecting Palo Alto
Connecting Palo Alto (formerly the Palo Alto Rail Program) is a community-based process to
address the increased traffic congestion expected when Caltrain completes the electrification of its
tracks and runs more trains through the corridor. The increased train traffic will lead to congestion
at intersections where cars wait for trains to pass. If High-Speed Rail comes to the corridor, the
increased traffic issues will be further compounded by even more trains. Community feedback and
collaboration are a vital part of this decision-making process that will affect future generations to
come. The work presented in this report is part of the Connecting Palo Alto process.
In addition, the City has maintained a lengthy public community engagement process for this project
and has made a concerted effort to engage community members from the start. The City has held
numerous workshops, roundtables, community meetings, a Community Advisory Panel (CAP)
which evolved into the Expanded Community Advisory Panel (XCAP), and City Council Rail
Committee meetings; built a database of interested stakeholders; sent out a questionnaire that
received 800 responses; produced a Connecting Palo Alto e-newsletter; posted extensively on
social media; and contacted local media about workshops, roundtables and the XCAP’s process.
And, during the pandemic, a Virtual Town Hall was created to try to get the word out.
More information about Connecting Palo Alto can be found on the Connecting Palo Alto website at
http://www.cityofpaloalto.org/connectingpaloalto.
More information about the Virtual Town Hall is available in Appendix A-4-7 Draft Virtual Town Hall

1.2. What is XCAP?
The City of Palo Alto has been working on separating cars, bikes and pedestrians from trains at
Caltrain crossings for the last several years. In June 2018, the Palo Alto Council approved a
Community Outreach Plan1 developed by AECOM and Apex Strategies that included plans for a
Community Advisory Panel known as CAP. The CAP was made up of 12 community members who
were chosen to ideally represent a diversity of thought and neighborhood/geographic
representation. The CAP’s responsibility was to connect with other community members/neighbors
to help inform the process. It had no authority to advise on what grade separation alternatives are
best for Palo Alto. The CAP participated in many meetings, but they were unable to create their
own agendas and were ultimately only able to respond to what was given to them by Staff and the
Consultants and communicate that information to their networks.
In April 2019, the City Council voted2 to create the Expanded Community Advisory Panel (XCAP)
which included eight original members from the CAP, and six new appointees. The transition from
CAP to XCAP initially had similar function, where the group was listening to presentations by the
consultants and Staff but were not able to set their own agendas. On September 9, 2020, the
Expanded Community Advisory Panel was formalized3 as a body subject to the Brown Act that can
vote and make recommendations directly to the City Council with the City Manager’s Office
providing Staff to the XCAP. The XCAP is tasked with evaluating all the information related to
grade crossing alternatives, making appropriate recommendations, and providing other relevant
feedback to the City Council.
1.3. What Will Happen Once XCAP Makes Its Recommendations?
XCAP will present its findings to the City Council early 2021, likely through a series of City Council
Study Sessions to be able to answer any in-depth questions the Council might have on the XCAP’s
report and work completed. The XCAP is a volunteer group that has worked diligently to provide
the City Council and the community the best possible information and recommendations with
respect to grade separations. Ultimately, the elected City Council is responsible for making
decisions. The City Council will receive all of the XCAP’s work and may choose to follow all, some,
or none of the XCAP’s recommendations.
1.4. COVID19 Pandemic
In March 2020, the Bay Area began to feel the effects of the coronavirus (COVID19) pandemic.
While the long-term impacts are difficult to predict during the ongoing pandemic, the immediate
impacts and how they’ve impacted this process have been described throughout this report.

1.5. What is an At-Grade Crossing and What is a Grade
Separation?
An at-grade crossing (or level grade crossing) is when there is no separation between trains and
cars and when a train comes at the existing grade, flashing lights and crossing gates prevent cars
from crossing the tracks.
A grade separation is a roadway that is re-aligned over or under a railway to eliminate hazards.
Viaducts are elevated grade separations, where the train is completely elevated above the roadway
on a long bridge or series of bridges, usually supported by a series of arches or on spans between
tall towers. Hybrids are where the train is partially elevated on an earthen berm that forms a wall
and the road is sunken down in a shallow trench. Below grade separations are Tunnels, where the
train is completely submerged underground and not visible, and Trenches, where the train is in an
open ditch while cars travel flat across the ditch.
1.6. Palo Alto’s Grade Crossings
Today, Palo Alto has seven places where the train tracks and roads intersect with the Caltrain
tracks. From North to South, they are Palo Alto Avenue, University Avenue, Embarcadero Road,
Churchill Avenue, Oregon Expressway, Meadow Avenue, and West Charleston Road. University
Avenue (built in 1940) and Embarcadero Road (built in1936) are both hybrids (where the road is
partly depressed, and the tracks are raised) and Oregon Expressway (built in 1959) is an
underpass (where the road is entirely depressed).

The focus of this report is three of the remaining at-grade crossings on the Caltrain Right of Way
(ROW): Churchill Avenue, Meadow Avenue and West Charleston Road. The fourth, Palo Alto
Avenue, will be studied as part of the Downtown Coordinated Area Plan.
1.7. Caltrain’s Grade Separation Plans
Plans to convert the Caltrain system from diesel trains to electric trains have existed since 1998, but
were finally realized in May 2017, when the Caltrain Electrification project finally received funds
from the Federal Transit Administration as part of funding provided for the California High-Speed
Rail Project.4 Electrification of the corridor is currently underway and upon completion (currently
estimated as 2023), Caltrain will be able to run many more trains per hour with greater efficiency.
Running more trains will benefit Palo Alto, but will cause congestion at intersections due to
increased grade crossing gate down time as cars wait for trains. Grade separations are needed to
alleviate that congestion and once built, will help Caltrain continue to expand its service.
In October 2019, the Caltrain Board approved their Business Plan Service Vision which further
details the significant expansion of Caltrain service and the need for a fully grade separated
corridor, with a price tag of between $8.5 and $ 11.1 Billion.5 Caltrain’s studies indicated pent-up
demand that could increase ridership by 3-4x by 2040 (note: these estimates were pre-pandemic).
The forecasted level of ridership would be the equivalent of removing an entire US 101’s worth of
cars off the freeway - and off the local streets leading to and from the freeway.
According to Caltrain’s pre-pandemic plans, Electrification is scheduled to be completed in 2023.
Once completed, there will be an expected increase in peak hour service from a total of 10 peak
hour trains to 12 peak hour trains, which will increase the amount of time that the protective gates
are down and therefore increase crosstown travel delays. In February 2020, before the emergence
of the coronavirus crisis, Caltrain had identified a shorter-term set of investments that could
increase ridership by 20,000 to 25,000 between 2027 and 2030. These investments would enable
increasing frequency to 16 peak hour trains. This change would create noticeable additional delays
for crosstown travel above the 12 peak hour trains planned for 2023.
In addition to Electrification, the passage of Santa Clara County’s Measure B in 2016 provided
some of the funding necessary to begin planning and building these grade separations in Palo Alto.
(See Section 2.8.1 Santa Clara County Measure B and also see Appendix C - History of Grade
Separation Funding Sources). The Electrification of Caltrain and the availability of Measure B funds
has driven the need for Palo Alto to build grade separations.

1.8. Palo Alto’s Need for Grade Separations
Grade separations in Palo Alto are needed to:
● Reduce congestion from increased trains
● Improve safety
● Meet the goals of the City of Palo Alto Comprehensive Plan 2030
● Support public transit goals
1.8.1. Reduce Congestion from Increased Trains
One of the most significant opportunities to reduce traffic congestion in Palo Alto would be the
creation of grade separations. In order to meet State goals of reducing greenhouse gas emissions,
state law favors public transit over car traffic - hence trains have a priority over cars when traveling
through a City.
Normal traffic signals at intersections have a sequence that allows all 4 directions (in a 4-way
signal) to take roughly equal turns in getting through the intersection before restarting the sequence
Since trains have priority over vehicles, this is not true at train/vehicle intersections. Instead, when
a train approaches the intersection the traffic signal modes are changed, the red warning lights
flash and the crossing gates come down to stop cars, bikes, and pedestrians from proceeding and
who thus face delays until the train passes and the signaling system resets.
As the number of trains increases, signal preemption events increasingly interrupt the ability of the
traffic signals to complete their normal sequence. When this happens repeatedly, as is the case
when multiple trains come in a short period of time, cars are unable to clear the intersections
(unclearable queues) leading to increased traffic jams and congestion. (Also see Appendix A-4
Queue lengths at Churchill 10-16-19)
The graphic below from Caltrain estimates the delay times that could occur with their future service
scenarios (Baseline, Moderate and High).6

Note: In the above chart, in the High Growth Scenario, passing tracks are needed, creating a four-track segment. The
FRA requires a grade separation when there are four tracks.
Introduction
8
Pre-COVID, at peak hours in the morning and afternoon, traffic signals were disrupted up to ten
times in a 60-minute period. Due to inconsistencies in the boarding process, the train schedule is
not precise, which means traffic signals cannot be easily synchronized to deal with multiple
preemption events.
1.8.2. Improve Safety
Safety is another reason for removing at-grade crossings. Every time cars, pedestrians, and
cyclists are in close proximity to trains there is potential for conflict. Pre-pandemic, 96 trains a day
traveled the Palo Alto corridor at speeds up to 79 miles per hour, and at the four at-grade crossings
there are a total of over 50,000 crossings per day. According to the Federal Railway
Administration, Charleston Avenue has the 19th highest7 “accident prediction value” in California,
and the second highest on the Caltrain system. Caltrain recently provided the following information
for the corridor8:
7 Charleston Avenue’s rank used to be much higher – today 15 out of the top 20 scores in the FRA’s system are occupied by a light rail
system in San Diego with a top speed of 30 miles per hour. Charleston has the fourth highest score in California amongst non-light-rail
systems.

Introduction

Chapter 6 on Safety includes more detail on both the history of rail accidents in Palo Alto and
specific suggestions to ensure that anything that is constructed is as safe as it can be.
1.8.3. Meet the Goals of Palo Alto’s Comprehensive Plan 2030
The Palo Alto Comprehensive Plan contains the City’s official policies on land use and community
design, transportation, housing, natural environment, safety, business and economics and
community services. The Plan is used by the City Council and the Planning and Transportation
Commission to evaluate land use changes and to make funding and budget decisions. And it is
used by City staff to regulate building and development and to make recommendations on projects.
It is used by citizens and neighborhood groups to understand the City’s long-range plans and
proposals for different geographic areas and it provides the basis for the City’s development
regulations and the foundation for its capital improvements program.
One of the eight major themes of the Comprehensive Plan (Comp Plan) is reducing dependency on
single occupancy vehicles. The City’s multipronged strategy includes improving bicycle and
pedestrian access throughout the City while also supporting the development of further transit
options in the City and throughout the region.
The Comp Plan states “Caltrain grade separations will be prioritized to improve east-west
connections for automobiles, transit, pedestrians and bicyclists, and to reduce traffic
congestion, improve safety and reduce noise impacts.” 9 The Comp Plan also has several
other policies related to grade separations and to creating better East/West bicycle and pedestrian
connectivity across the Caltrain tracks. The plan also “recognizes the regional nature of its

transportation system” and seeks to prioritize “Caltrain service improvements and railroad
grade separations.” The appendix includes the Implementation Plan portion of the
Comprehensive Plan with highlights on all of the visions, goals and policies that might
intersect with future grade separation planning and projects. (See Appendix C-12 Palo Alto
Comprehensive Plan Excerpts for more information)
1.8.4. Support Public Transit Goals
Another goal of the Comprehensive Plan is support of public transit alternatives to reach the goal of
reducing single occupancy vehicle use. Caltrain is the backbone of the transportation systems on
the Peninsula and plays a significant transportation role for Palo Alto and the region. Pre-
pandemic, Palo Alto had the second highest ridership outside of San Francisco given it is a
significant job center in the region. As part of its Long-Range Service Vision (Business Plan),
Caltrain created a booklet highlighting key statistics related to Caltrain in Palo Alto.10
Caltrain’s growth in the region (pre COVID19) and its expected future expansion are fueled by a
number of factors including electrification, worsening of congestion and overall Bay Area growth,
and the eventual completion of the Central Subway project11 (linking the Muni Metro light rail system
to Caltrain at 4th and King streets and Chinatown, with stops in South of Market (SoMa) and Union
Square) allowing a Caltrain connection into the densest parts of San Francisco. The potential

Introduction

arrival of California High-Speed Rail on the Peninsula and the additional trains they might run only
exacerbates the need for grade separations.
Caltrain also plays a key role in Palo Alto’s relationship with Stanford University. Stanford’s growth
is limited by the General Use Permit between Stanford and Santa Clara County whereby Stanford is
committed to keep single occupancy vehicle trips to a minimum. If Stanford goes over the agreed
amount, they must pay for mitigations. As a result, Stanford has developed a commuter program
that relies heavily on Caltrain. In fact, Stanford recently donated $1 million dollars to Caltrain and
signed an agreement to help in the development of Caltrain’s Business Plan to ensure expanded
service to help mitigate the impacts of Stanford’s plans to continue to grow.12
1.9. Impacts of the Pandemic
As of the date of this report, the US economy has been severely impacted in response to Covid19.
Caltrain’s ridership has plummeted as a result of the increased number of people working from
home and the general decline in the economy. Caltrain ridership suffered a greater than 90% drop
since April 2020.13 Caltrain’s ridership relative to other transit agencies has been more severe
because the majority of Caltrain riders prior to the pandemic were typically riders with greater
economic means and who owned vehicles, but still chose to commute by train.14
The near-term economic outlook is highly uncertain, and the timing and shape of the economic
recovery cannot be predicted. During the recovery period there will likely be a transition period
during which Caltrain regains some but not all of its pre-Covid ridership. Thus, it is not possible
now to predict exactly when Caltrain will need to increase its services to accommodate increased
ridership levels. However, the economy of the country and the region has always recovered from
prior economic downturns including the Great Depression, the “Great Recession” of 2008-2009,
and the local “tech bubble” of 2000-2001. There is every reason to believe that the Bay Area will
recover and thrive, because the fundamental drivers of Caltrain ridership, current population jobs
and expected population and jobs growth, are still in place. Directly to this point, a Caltrain “Covid-
19” ridership survey with over 1600 responses indicated that 55% of respondents will ride Caltrain
post-pandemic as often as or more often than before.15 Less than 1% of respondents answered
that their company will expect all employees to work remotely.16
In the meantime, the impacts of the pandemic have shifted Caltrain ridership patterns, with
Palo Alto now being the top transit stop, surpassing San Francisco.

In addition, on November 3, 2020 Measure RR passed, finally providing dedicated funding for
Caltrain (see Section 2.8.3 Measure RR). The fact that during a pandemic in which Caltrain’s
ridership has plummeted, Measure RR surpassed the 66.67% threshold in San Francisco, San
Mateo and Santa Clara Counties is a strong indication of the voters’ confidence that Caltrain
remains an important part of the regional transit system that continues to merit significant
investment.
It is also possible that grade separation projects would be included in a future “economic stimulus”
passed by Congress as part of its response to the current economic situation or as part of a major
infrastructure bill. If history is a guide, qualifying projects will need to be “shovel ready” within
several years of passage of such laws.
For these reasons, XCAP believes it is prudent to continue planning work on grade separation
projects in Palo Alto.
Influencing Factors
13
2. Influencing Factors
This Chapter covers a variety of factors that influence any potential decisions related to grade
separations; from general technical considerations, like freight operations, to relevant Caltrain
and High-Speed Rail policies and the changing need for and funding of grade separations.
While not an exhaustive list, it attempts to draw attention to issues that should be considered.
2.1. City Council Criteria
In September 2017, the City Council adopted evaluation criteria they intended to use for grade
separation evaluations. In 2018-2019 the Council had significant discussion about removing the
tiered levels of the criteria. However, as the process evolved with the formation of the CAP and
XCAP, the criteria never returned to Council for further discussion.
Source: https://connectingpaloalto.com/wp-content/uploads/2019/11/Item-6-Final-Memo-Review-Council-Adopted-Criteria.pdf
The City Council adopted criteria to form the basis for a summary document created by the
consultants known as the Matrix that compares and contrasts the various alternatives.
The Matrix expands upon the Council’s criteria by including other factors that could be used to
make decisions. For more information about how the Comprehensive Plan might be applied to
Council Criteria, Appendix A-4-3 Staff Update: Follow up to XCAP Criteria Questions 4-22-20.

2.2. Eminent Domain and Property Acquisition
In the development of the Council Criteria and in subsequent discussions, the issue of eminent
domain has been a key component. The Council has repeatedly indicated that they want to
minimize the amount of eminent domain, but they very specifically did not prohibit the use of
eminent domain outright and the issue of negotiated property acquisition was not fully pursued.
The criteria specifically state “Cost: minimize right-of-way acquisition by eminent domain”.
XCAP invited land use attorney Norm Matteoni to make a presentation so the public, XCAP,
Council and Staff could better understand the eminent domain process. A transcript17 of that
meeting was posted on the Connecting Palo Alto website, as well as the attachment18 provided
by Mr. Matteoni providing an overview of the eminent domain process and property owners’
rights under the law. This information is available in Appendix B–6 Eminent Domain
Information.
2.3. Freight
Freight trains play a regional role in moving goods through the area and reducing the number of
trucks needed, reducing pollution and traffic. On the Caltrain ROW, Union Pacific carries freight
on diesel trains that travel through Palo Alto three times per night, six nights per week. Even
after Caltrain is electrified, these diesel freight trains will continue to operate. The majority of
the customers using freight are in the Port of Redwood City, South San Francisco, and the Port
of San Francisco.
Caltrain owns the right-of-way in Palo Alto, but Union Pacific has several trackage rights
agreements19 that allow them to travel on the corridor. As part of these agreements, throughout
the Electrification project and any grade separation projects, Caltrain and Union Pacific must be
able to maintain operations. In general, the agreements also provide that Caltrain will work with
Union Pacific when making any changes to the infrastructure on the corridor.
While freight represents less than 5% of all the train operations on the Caltrain corridor, the
technical constraints of considering freight when designing grade separations have a significant
impact on design flexibility. Electrified trains can climb and descend at steeper slopes than
freight trains. The majority of the Caltrain corridor has a maximum of 1% slope and that is the
present Caltrain standard. When raising or lowering the train tracks to go over or under a road,
the grade at which it can travel must be flatter, which in turn requires more distance than a
steeper vertical grade. A rise of one foot in elevation in 100 feet of track is a 1% ascending
grade. Similarly, a decrease of one foot in elevation in 100 feet of track is a descending grade
of 1%. A change from a 1% grade to a 2% is a 50% decrease in the horizontal distance needed
to achieve the change in grade. The following graphic illustrates this concept:

19https://www.caltrain.com/about/JPB-Agreements.html
Influencing Factors
15
Freight trains can travel at steeper than 1% grade, and as can be seen above, a small change
makes a big difference. In 2017, Union Pacific announced they were looking for a company to
sublet their trackage rights to operate freight on the Peninsula. The mayors of San Francisco
and San Jose wrote a letter to Union Pacific asking them to consider finding an operator that
would be comfortable operating at 2% grade because “In anticipation of Caltrain electrification,
the Peninsula cities expect to work with Caltrain to amend the design criteria to provide for a two
percent grade design standard.”20 While this change hasn’t happened yet, it indicates the
importance of this technical requirement on the ability to build grade separations on the corridor
at minimal construction cost. The needs of freight can also make grade separations designs
more expensive independent of grade standards, because they require higher and wider
clearances than Caltrain trains.
A September 2020 report recently revealed that Union Pacific is now considering selling its
trackage rights to freight on the Peninsula and the JPB is in negotiations with Union Pacific to
acquire the short line rights for the tracks north of Santa Clara21 This developing situation could
have implications for design. Policymakers and staff should continue to advocate to
Caltrain for a two percent grade design standard. Five of the nine grade separation design
alternatives considered by XCAP would require a design exception to the one percent standard.
2.4. High Speed Rail and Caltrain Operations
In addition to freight, Caltrain may have High Speed Rail operating on the corridor in the future.
In 2008, voters approved Proposition 1A, which authorized funds for the construction of a high-
speed rail line between San Francisco and Los Angeles, as part of an eventual system that
would also extend to Sacramento in the north and San Diego in the south. HSR trains would
run on the Caltrain line between San Jose and San Francisco. The estimated date for HSR
operation on the Peninsula Corridor has recently been extended to 2031, and the project has
had implementation and funding challenges. Many question whether it will ever arrive on the
Peninsula. At minimum, its arrival date is likely to be later than 2031, but its potential arrival has
impacts on the corridor planning that have to be taken into account.

PCEP+PMOC+Quarterly+Monitoring+Report.pdf
Influencing Factors
16
In 2012, Caltrain and High-Speed Rail signed a Memorandum of Understanding22 committing to
a Blended System on the Caltrain corridor which establishes primarily two shared tracks
substantially within the existing Caltrain corridor. From Caltrain’s website: “Additional system
improvements that need to be defined include HSR stations, passing tracks that can be used by
HSR trains to bypass the Caltrain trains that need to stop more frequently, at-grade crossing
improvements, and system upgrades to support higher train speeds. Grade separations, a
storage/maintenance facility, and other system elements will also be considered in defining the
blended system.”23 According to Caltrain’s Business Plan, if HSR comes to the corridor, it will
need passing tracks in several areas, including Palo Alto and Redwood City to overtake
Caltrain.
HSR thinks otherwise. It claims that it does not need passing tracks in Palo Alto if Caltrain is
willing to wait at stations or on sidings while High-Speed Rail passes. Studies have shown,
however, that this would significantly impact Caltrain’s operational schedule and Caltrain would
be unable to achieve their Business Plan goals. Caltrain recently sent a letter to High-Speed
Rail as part of HSR’s Environmental Impact Report for its proposed San Francisco to San Jose
route that made it clear it finds waiting at stations or sidings unacceptable and expects HSR to
pay for passing tracks if they decide to run service on the Peninsula. (See Appendix B-8-C -
Caltrain Letter to High-Speed Rail - Re: Preferred Alternatives 8-22-19)
It should be noted that under the rules of the FRA, if there are four tracks built, a grade
separation MUST be built, as it is unsafe and unacceptable for cars to drive over four tracks of
trains at a level grade crossing.
2.5. Caltrain Rail Corridor Use Policy and Four-Tracks
The Caltrain Board of Directors, known as the Peninsula Joint Powers Board (JPB) is the owner
and operator of the Caltrain corridor. The JPB has to ultimately approve all designs for
grade separations. As part of its Long-Term Service Vision, Caltrain Board’s recently adopted
the Rail Corridor Use Policy (RCUP) (See Appendix B-8-G Caltrain Rail Corridor Use Policy
2-6-20) which in part states that Caltrain will not allow grade separations to be built that would
preclude the ability to run a four-track system. From Caltrain’s email to Palo Alto City Staff:
“The exact location of a potential four track segment is yet to be defined, however.
For the purposes of RCUP, which governs Caltrain’s use of its own property, we took
the most conservative approach and considered the potential for a 4-track segment
between San Francisquito Creek Bridge in Palo Alto to just through the Mountain
View Station (the area in which a 4-tracks segment is operationally viable for the
intended purpose). The ultimate extent of the area preserved for 4-tracks does not
need to encompass this full length. However, we would need to work with the City to
advance thinking about the City’s potential capital projects along the corridor to then

Influencing Factors
17
make decisions that could constrain the extent of the area under consideration. Until
that time, Caltrain will take a very conservative approach – as specified through the
RCUP – when it comes to any potential long-term encumbrance of our property.”24
Caltrain has made it clear that any alternatives considered for grade crossings should
not preclude the ability to deliver a four-track segment. While the City could initiate the
RCUP review process to petition Caltrain staff review the compatibility, Caltrain says “in order to
be considered for an exception to the RCUP and be considered compatible, the onus would be
on the City to show via conceptual designs that a potential future four track segment
would not be precluded in this area…” Caltrain goes further and explains “even if the City did
this and the proposal was able to be considered ‘potentially viable’ by receiving a compatibility
exception through the RCUP, it would still need to undergo substantial design, engineering, and
regulatory review before it would be approved as a use for JPB property.”
2.6. Caltrain Corridor Wide Grade Separation Study
In July 2020, Caltrain Representative Sebastian Petty described the Caltrain Corridor Wide
Grade Separation Study that is planned. The study represents Caltrain’s first attempt to
develop a cohesive grade separation strategy for the corridor. A synopsis of the Caltrain
presentation was made available in XCAP’s update to City Council in Sept 2020 (see
Appendix C-4-6 Update #6 09-09-20) and is excerpted below:
● Was scheduled to begin Fall of 2020 (funding secured in this past year’s capital budget).
Budget authorized hiring a single point of contact to manage work broken up between
multiple contractors and phases. Phase 1: expected to take 6 months; entire study
about 2.5 years. (This has been delayed due to COVID and, as of the writing of this
report, is expected to start early in 2021).
● Caltrain will not be involved in specific designs for each City. A corridor and community
process, including all local jurisdictions on the corridor, regional and state partners will
work to develop and determine the scope, timeframe, contracting method and how the
study should be governed. Focus will be policy framework, not specific grade separation
or crossing designs.
● Phase 2: Will echo what was heard and seek feedback from city representatives,
especially on standards and construction methods and why they’re needed to
understand mutual implications of all decisions.
● Will consider economies of scale, construction standards and design standards
comprehensively (so individual projects are not asked to go through onerous design
exemption processes) and how construction contracting, and sequencing approaches
can be used to keep costs and impacts under control. Will include organization analysis
and governance around project delivery vs. operations and corridor management,

structure for decision making on issues that span multiple jurisdictions and impact both
cities and rail operations and structure for administering funding.
● Will evaluate, at a corridor level, what standards should be used rather than taking a
case-by-case exception approach to ensure Union Pacific is comfortable.
The Corridor-wide grade separation study is also expected to consider grouping grade
separation projects together to be able to receive more federal funding.
2.7. Caltrain Governance Reform
As part of its Business Plan, Caltrain is reviewing a possible reform of its governance structure
which, if pursued, could also impact how grade separation projects are designed, managed, and
funded. In July 2019, Caltrain completed an Organizational Assessment Report25 which
explained that the California Legislature has provided enabling authority for two types of
structures created for the purpose of building major capital projects. These are Special
Construction Authorities and Grade Separation Districts. A Special Construction Authority is an
independent agency created by the State legislature to plan and construct specific projects,
which, if created, would require comprehensive agreements addressing funding mechanisms,
planning and construction requirements, technical specification reviews, and operational
agreements.26 By contrast, a Grade Separation District could be created if a board of
supervisors in any county could pass a resolution to create a grade separation district, upon a
finding that the safety and welfare of the residents of contiguous areas within the county require
the formation of a district to provide for a separation of grade. The Grade Separation District
would need to be ratified by a majority of the voters within the proposed district in a general
election. Under existing legislation, the district would have a 5-member governing board that
confers broad powers to the agency, including the power to plan, design and build the project
and to exercise the power of eminent domain. A grade separation district also has the power to
issue bonds and to levy property taxes subject to obtaining approval from 2/3 of those who cast
ballots in a duly called election.
From the report:
“Although implementation of grade separation projects to date within the Caltrain rail corridor
have been designed and constructed by means other than a grade separation district (e.g.,
contractual arrangements between local funding agencies, the JPB and the cities or county
in the jurisdiction of the project), there is precedent for the creation of such districts
elsewhere in California. In 1954, the Kern County Board of Supervisors invoked the grade
separation district enabling authority, resulting in the creation of the Greater Bakersfield
Separation of Grade District whose duties were to separate dangerous at-grade
intersections of roadways and railroads by means of underpasses or overpasses.”27

19
If Caltrain and/or Santa Clara County were to pursue either of these governance forms,
the City of Palo Alto would need to consider their impact on Palo Alto’s grade separation
strategies.
2.8. Funding for Grade Separations
The City Council directed XCAP not to consider the financing of grade separations and it has
not. However, since two significant funding events specific to grade separations were part of
the rationale for the City’s decision to invest time and money on this issue (2016 Measure B and
Caltrain Electrification Funding), XCAP believes it appropriate to comment on the present status
of these potential funding sources. Additional historic information related to grade separations
is available in Appendix C-2 History of Grade Separation Funding Sources.
2.8.1. Santa Clara County Measure B (2016)
Santa Clara County’s Measure B (2016), a 30-year, half-cent countywide sales tax to enhance
transit, highways, expressways, and active transportation (bicycles, pedestrians, and complete
streets) is considered a substantive “down payment” for grade separations. The measure
earmarked $700 million for eight grade separations including four in Palo Alto (Palo Alto
Avenue, Churchill Avenue, East Meadow Drive and Charleston Road), two in Mountain View
(Rengstorff Avenue and Castro Street) and two in Sunnyvale (Mary Avenue and Sunnyvale
Avenue). The total cost of the eight grade separations will vastly exceed this amount. In order
for cities to access Measure B funding, projects must include a minimum of 10% contribution of
non-2016 Measure B funding.
Palo Alto, Mountain View and Sunnyvale have yet to negotiate with VTA how the money will be
divided and distributed, but some monies have been distributed to Mountain View to begin
planning and design. Mountain View recently signed the Castro Street Grade Separation
Project Cooperative Agreement28 to access Measure B funding and work is currently underway
for 35% engineering of the Rengstorff project.29
In 2000 and 2008, Santa Clara County passed tax measures aimed at making a variety of
improvements, including for Caltrain, however cost overruns on BART have meant the promised
funds have been raided by VTA. Policymakers must remain focused to ensure that the 2016
Measure B dollars are not raided to cover the cost overruns of the BART extension to San Jose.
2.8.2. Corridor-wide Funding
Caltrain is undertaking a Corridor-wide Grade Separation Study which is expected to look at the
potential need to change historic funding strategies along the corridor in order to achieve their
Long-term Service Vision Goal.

Influencing Factors
20
Policymakers should note that since the need for grade separations is now focused on
public transit as a regional priority to meet transportation and climate goals, the manner
in which these projects are managed, grouped, prioritized, and funded could dramatically
shift away from the previously city/county driven model that focused on grade
separations for vehicle traffic.
2.8.3. Measure RR
Despite being the seventh largest commuter rail service in the nation, unlike most transit
agencies, Caltrain has not had a dedicated source of funding. Since its inception, Caltrain has
relied on revenue from passenger fares (70% of operating budget – highest percentage in the
country) and on contributions from its Member Agencies: San Mateo County Transit District
(SMCTD), Santa Clara Valley Transportation Authority (VTA) and City and County of
San Francisco (CCSF).30
Each of the Member Agencies (a) contributes an equal amount of capital funding each year and
(b) supplements operating funding based on the percentage of system ridership originating in
each County. The levels of both capital and operating funding are determined by the funding
capacity of the Member Agency with the least ability to provide its share of funding in any given
year. The amount that Member Agency can make available then becomes the standard against
which the contributions of the other Member Agencies are calculated.
In the November 2020 election, voters approved Measure RR (2020) establishing a dedicated
source of funding for Caltrain as a 30 year one-eighth cent sales tax in San Francisco,
San Mateo and Santa Clara County which will provide approximately $100 million annually.
The impacts of this dedicated funding and the changes that might come from member agencies
and their previous funding commitments remains to be seen. The amount of money available
from Measure RR seems likely to be dedicated almost exclusively to operations and would likely
not have any excess funds for grade separations.

Ideas Discarded before XCAP Began

3. Ideas Discarded before XCAP Began
Before XCAP began, City Council reviewed and discarded several grade separation concepts
that it determined to be infeasible or undesirable. This section briefly discusses these discarded
alternatives for comprehensiveness purposes and the rationale for their being discarded. The
following Staff report discusses the discarded alternatives:
https://www.cityofpaloalto.org/civicax/filebank/documents/65124.
3.1. Citywide Tunnel
In May 2019, the City Council on a 4-1 vote (Tanaka dissenting, Kniss and Filseth recused)
eliminated the “citywide tunnel” alternative. “Citywide” is a misnomer in that for a tunnel to run
from one end of the City to the other it would have to extend into Menlo Park and Mountain
View. The tunnel proposed would have originated at the University Avenue station and ended
near San Antonio Avenue. The Council’s rationale primarily focused on the estimated cost of
$2.5 to $3.8 billion, but concern was also expressed for the significant property acquisition,
mainly residential, which would be required.
The profile and typical section drawings can be found in the Appendix A 2 and the animation
can be found at: https://vimeo.com/325481133/e987af4a60.
3.2. Traditional Underpasses
Early conceptual designs for traditional Underpasses (where the train remains where it is, and
the road is fully submerged) for Churchill Avenue and Meadow Drive/Charleston Road were
briefly studied and rejected in 2014 based on consultant Hatch Mott McDonald’s study31
because of the very large number of property acquisitions (~40) along Churchill Avenue,
Meadow Drive, Charleston Road and Alma Street which would be required.32
In late 2019, resident Elizabeth Alexis, recognized that the early conceptual work done on the
underpasses at Meadow and Charleston assumed including more traffic lanes than would be
required. She proposed a modified Underpass Alternative for Meadow/Charleston which is
described and considered in Section 5.5.2.5.
3.3. Closure of Meadow Drive
With the Meadow Drive crossing being less than one mile away from Charleston crossing, the
issue of whether Meadow could be closed was raised. According to the Hexagon Traffic
Analysis of August 13, 2020, page 56, “The additional traffic on Charleston Road from the
proposed closure of E. Meadow Drive would cause these intersections to operate at

Ideas Discarded before XCAP Began
22
unacceptable levels of service. Therefore, closure of the E. Meadow Drive railroad crossing is
not recommended.” Based on this study, the XCAP did not consider a closure at Meadow.
3.4. Churchill Hybrid and Churchill Reverse Hybrid
The Churchill Hybrid and Churchill Reverse Hybrid were reviewed by City Council in May 2018.
In the Churchill Hybrid, the road is partially lowered, and the rail is partially raised. The Churchill
Reverse Hybrid (also named Shallow Trench) is where the road is partially raised, and the rail is
partially lowered. The City Staff report33 contains few details about why these options were not
advanced. Early conceptual drawings produced in 2018 show significant negative impacts to
adjacent residential properties due to raising and lowering the roadway which probably would
have required significant property acquisitions.
3.5. Ideas Submitted by XCAP to City Council but Rejected
XCAP received a presentation from its own member, Tony Carrasco, which included a concept
to build a Viaduct with a roundabout at Embarcadero. XCAP presented this concept to the City
Council but the Council chose not to study it.

4.1. Summary of Actions
XCAP evaluated three alternatives, the Closure plus Mitigations, the Partial Underpass and the
Viaduct for the Churchill Avenue rail crossing.34
XCAP voted to recommend Closure with Mitigations on 9/2/20 by a 6-to-3 vote (No: Phil Burton,
Nadia Naik, Keith Reckdahl). XCAP then had two subsequent votes to define the mitigations
and a preference for a Bike/pedestrian option. One that identified mitigations in addition to what
the consultants proposed, passed on 9/16/20 by a 7-0-2 vote (Abstained: Phil Burton, Tony
Carrasco).35 Of the two alternatives for Bike/pedestrian designs, XCAP voted on 9/16/20 7-0-2
vote (Abstained: Phil Burton, Tony Carrasco)36 to recommend Option 2 Bike/pedestrian
alternative for the Churchill Closure, which calls for a bicycle/pedestrian tunnel that runs down
the middle of Churchill east of Alma Street and then proceeds under Alma and the railroad
tracks.
The Recommendations, Majority and Minority Positions and suggestions for future areas of
study are in the latter part of this Chapter. If the Council decides to pursue either the Partial
Underpass or the Viaduct alternative instead, XCAP has also made suggestions on potential
improvements and areas of future study.
Fact Sheets for Churchill are available in Appendix A-1 Fact Sheets, renderings are available in
Appendix A-2 Renderings and Plans and animations and exhibits used for the Virtual Town Hall
are available in Appendix A-5 Links to Animations and Virtual Town Hall.
Note for the Reader: Colloquially, Palo Altans refer to Caltrain as traveling North/South.
Similarly, Alma Street is considered to run North/South where Old Palo Alto and Professorville
are considered East of Alma and Palo Alto High School, Southgate and Evergreen Park are
considered West of Alma. When looking at a map, however, Caltrain and Alma generally run
from Northwest to Southeast. All references to North, South, East and West in this report refer
to the colloquial direction, and all images created by the consultants have an arrow in the lower
right corner showing true North.
4.1.1. Closure with Mitigations
This alternative considers closing Churchill to vehicular traffic across the railroad tracks and
introducing mitigations at Embarcadero Road and Page Mill/Oregon Expressway to handle
traffic diverted from the closed Churchill intersection. In this alternative, the railroad tracks

would remain at their existing location and elevation. A separate tunnel would be provided for
pedestrians and cyclists to cross Alma at Churchill, enabling access to and from Palo Alto High
School, Stanford University, and points beyond.
Churchill Avenue would become a T-intersection with Alma Street on the east side and would
end at Mariposa Avenue on the west side. Two options for the Churchill Bike/pedestrian
undercrossing were studied.
4.1.1.1. Closure Option 1
The first option would allow bikes and pedestrians on the east side of Alma to use a call button
to activate a traffic signal to go across Alma and then descend a ramp that would run alongside
the train tracks, going under the tracks and emerging on the other side of the tracks via another
ramp running alongside the rail right of way. In this option, similar to the condition today, bikes
and pedestrians would cluster at the intersection waiting for the crosswalk signal.
Churchill Avenue
25
Churchill Avenue
26
4.1.1.2. Closure Option 2
The second option would provide a straight path running down the center of Churchill Avenue
under both Alma and the rail tracks, with vehicle traffic allowed on either side of the entrance to
the ramps along the east side. There would be complete separation of vehicle traffic from
cyclists and pedestrians, eliminating the need for bicycles/pedestrians to wait for traffic at Alma.

More detailed information about the Bike/Pedestrian tunnels is available in Appendix A-4-5 Churchill Pedestrian Tunnel Info.
Churchill Avenue
28
4.1.1.3. Additional Mitigations
As part of this alternative, the City would also construct several intersection improvements in
order to mitigate the anticipated diversion in traffic resulting from the closure. These
improvements would be constructed and funded as part of the overall project. They include:
A. Construction of a bike/pedestrian overcrossing at Embarcadero Road and Alma Street.
B. Reconstructing or replacing the existing Alma Street overpass over Embarcadero Road.
C. Adding a right turn lane from eastbound Embarcadero Road to Kingsley Avenue.
D. Adding a left turn lane from southbound Alma Street to Kingsley Avenue.
E. Installation of two new signal lights on the Alma Street overpass at Embarcadero Road,
at the Embarcadero slip road and at Kingsley Avenue.
F. Installing a new signal at Embarcadero Road/Kingsley Avenue/High Street with two
possible options: one that provides full connectivity to and from High Street, or an option
that maintains the movements to and from High Street as they are today.
G. Improvements at Embarcadero Road/High Street for bicycles and pedestrians per the
Neighborhood Traffic Safety and Bicycle Boulevard (NTSBB) projects plans.37
H. Optimize signal timing at El Camino and Embarcadero and install an additional
westbound left turn lane on Embarcadero onto El Camino and northbound right turn lane
on El Camino onto Embarcadero Road.
I. Signalize on Alma Street both on/off ramps at Alma and Oregon Expressway.
J. Optimize signal timing and install a westbound right turn lane and northbound right turn
lane from Oregon Expressway to El Camino Real.
These mitigations are visible in the figures below. Figure 8 shows Mitigations A through G,
Figure 9 shows Mitigation H, Figure 11 shows Mitigation I and Figure 10 shows Mitigation J.

4.1.2. Partial Underpass
The Partial Underpass would separate Churchill Avenue from the current Caltrain tracks via an
underpass. However, there would no longer be through traffic on Churchill Avenue east of
Alma; instead, it would now form a T-intersection.
Churchill Avenue
34
Traffic on eastbound Churchill Avenue from the Palo Alto High School/Castilleja Avenue intersection would descend and pass under
the railroad tracks, which would remain at their current grade. The down ramp would terminate at a lowered, signal-controlled,
T-intersection at Alma Street where vehicles could make a left turn onto northbound Alma Street or a right turn onto southbound
Alma Street, and then ascend and return to existing roadway grade along Alma Street. Thru traffic across Alma is prohibited.

Traffic on westbound Churchill Avenue would terminate at a T-intersection at Alma Street. Right turns only (onto northbound Alma
Street) would be permitted. Similarly, westbound traffic on Kellogg Avenue and Coleridge Avenue approaching Alma Street would be
permitted to make right turns only onto northbound Alma Street.
Churchill Avenue
38
Traffic on southbound Alma Street would operate as it does today except left turns onto Kellogg Avenue, Churchill Avenue and
Coleridge Avenue would not be permitted. The Caltrain tracks would be supported on a new rail bridge spanning a lowered Churchill
Avenue at approximately its current location. A separate pedestrian/bicycle crossing would be provided at Kellogg Avenue. From
westbound Kellogg Avenue, a 10-foot-wide path would descend at the center of the road, at which point it would widen to 20 feet and
cross under both Alma Street and the Caltrain tracks, joining the Embarcadero Bike Path adjacent to Palo Alto High School.

4.1.3. Viaduct
In this alternative the railroad tracks would be elevated on a structure, with the bottom of the structure about 15 feet above ground,
(20 feet above ground to top of rail). The viaduct would be topped by six-foot sound wall barriers (parapets), plus an overhead
contact system for electrical power that reaches a height of about 30 feet above the top of rail.

The new electrified railroad tracks would be built at the same location as the existing railroad
tracks and, going north to south, would begin rising near Homer Avenue, remain elevated over
Churchill Avenue, and return to the existing track grade near the California Avenue Station.
The Stanford game day station38 would be eliminated. The roadway at Churchill Avenue would
remain at its existing grade and have a similar configuration to what exists today. This design
would require expanding the width of Churchill Avenue through the underpass of the railroad to
accommodate a new column supporting the railroad structure.
Please see Appendix A-1-D Churchill Avenue Vicinity Viaduct Fact Sheet for more information.
4.2. Compared with City Council-Adopted Criteria
This section compares the alternatives with the city-council adopted criteria for grade
separations.
4.2.1.1. Facilitate Movement across the Corridor for All Modes of Transportation
Under Closure with Mitigations, Churchill Avenue vehicular traffic will be somewhat impeded
since traffic will be closed to vehicles at the railroad tracks. On the other hand, the movements
of pedestrians and cyclists will be safer and more efficient as they will be grade separated from
both the railroad and Alma vehicular traffic under Bike/Pedestrian Option 2.
In the Viaduct alternative, Churchill Avenue will be grade separated from the railroad for all
modes and will remain open. The Viaduct thus would provide opportunities for additional traffic
volumes for all modes.
With the Partial Underpass alternative, Churchill Avenue would be grade separated from the
railroad for all modes and remain open, with the exception that through traffic on Churchill
Avenue and various turns from and to Alma would no longer be possible. Thus, some vehicular
traffic would have to take alternate routes.
4.2.1.2. Reduce Delay and Congestion for Vehicular Traffic at Rail Crossings
The Closure with Mitigations alternative will reduce delay and congestion and delay on Alma but
will adversely affect nearby intersections. The mitigations described are intended to reduce
these impacts.
Under the Viaduct alternative, rail-crossing-related delay and congestion is eliminated on Alma.
No nearby streets would be negatively affected.
In the Partial Underpass alternative, rail-crossing-related delay and congestion on Alma would
be eliminated, but certain turning movements to and from Alma would also be eliminated.

Questions 4-22-20
Churchill Avenue
45
In all alternatives, the railroad crossing gates and warning lights at Churchill Avenue would
be removed.
4.2.1.3. Support Continued Rail Operations and Caltrain Service Improvements
With the Viaduct alternative, the Stanford game day station would be eliminated.
4.2.1.4. Cost
Closure plus Mitigations is by far the lowest cost option at $50 to $65 million, where the cost
comes primarily from the mitigations.
The Partial Underpass alternative is estimated to cost $160-200 million, and the Viaduct is
estimated to cost $300-$400 million.
4.2.1.5. Minimize Right-of-Way Acquisition
In both the Closure with Mitigations and Viaduct options, no acquisition of private properties
would be required.
In the Closure with Mitigations alternative, there would likely be some minimal impacts to
Palo Alto High School property. There could also be some parking loss on the east side of
Churchill Avenue for the bike/pedestrian undercrossing (Option 2).
In the Partial Underpass alternative, driveway modifications would likely be required due to the
removal of planting strips along Alma Street. Some minor “sliver” acquisition of the high school
and/or residential properties fronting Churchill Avenue on the west side of the tracks might also
be required. Most significantly, this option’s bike/pedestrian tunnel on Kellogg Avenue would
require the elimination of on-street parking on both sides of Kellogg Avenue along the
bike/pedestrian ramp for approximately 250-300 feet from Alma Street at an 8% grade. Two
“sliver” acquisitions on the corners of Kellogg and Alma might also be required.
4.2.1.6. Reduce Rail Noise and Vibration
In all alternatives, train horn noise and crossing gate warning bells would be eliminated with the
removal of the at-grade crossings. Eliminating these horn and bell sounds means that all
alternatives will be at least 10 dBA quieter than the situation today.
Electric multiple unit (“EMU”) trains using electric motors, compared to the diesel engines of
existing Caltrain trains, will also reduce noise. Note that freight trains running on the tracks will
still retain their diesel engines.
Churchill Avenue
46
In general, the Viaduct and the Partial Underpass would have slightly less noise than a Closure
with Mitigations (a difference of about 3 dBA, which is considered barely perceptible)39. If a six-
foot-high noise barrier is added to the Closure with Mitigations, then it becomes equal to the
others. However, if the Partial Underpass gets a noise barrier, it does significantly better (about
6 dBA difference).
The Viaduct would provide the most reduction of vibration impacts for homes on both the east
and west sides of the track. The Closure with Mitigations would have no change in vibration
impacts and the Partial Underpass would have little to no change.
4.2.1.7. Minimize Visual Changes along the Corridor
The Closure with Mitigations alternative, with the railroad tracks remaining at existing grade,
produces the least visual change of the three alternatives. Residual roadway areas from
closure would provide opportunities for landscaping and thus potentially enhance the viewscape
when compared with current conditions.
The visual impact of the Viaduct option is the most significant of three options, with railroad
tracks approximately 20 feet above the current grade and the trains and attendant structures
such as electrical power line poles 30 feet higher. Landscaping with trees could be incorporated
for screening where feasible. Depending on the vantage point, the Partial Underpass option
would have an impact on views, primarily from the underpass structure itself. Also, mature trees
within the Alma Street planting strip, from just north of Kellogg Avenue to just south of Coleridge
Avenue, would be removed with landscaping restoration limited due to space constraints.
4.2.1.8. Minimize Disruption and Duration of Construction
Closure with Mitigations would be the least disruptive alternative, requiring only minimal road
closures for the mitigations (nights/weekends only). Construction would last for approximately
2 years. It would also have minor noise and vibration impacts during construction.
The Viaduct alternative would require extended lane reductions at Alma Street (one lane in each
direction) for the shoofly track. Construction would also last for approximately 2 years and would
have moderate noise and vibration impacts.
The Partial Underpass would require closure of Churchill Avenue between Alma Street and
Mariposa Avenue for the majority of its 2.5 to 3 years of construction. Alma Street would be
one-way northbound for approximately 6+ months. There would be severe noise and vibration
impacts during construction according to the noise report submitted to XCAP.40
39 From PDF page 7 of Appendix B-1-4 Noise and Vibration Comparative Analysis Report: “...it is widely accepted that people are
able to begin to detect sound level increases of 3 dB in typical noisy environments. Further, a 5-dB increase is generally perceived
as a distinctly noticeable increase, and a 10-dB increase is generally perceived as a doubling of loudness. Therefore, a doubling of
sound energy (e.g., doubling the volume of traffic on a highway) that would result in a 3-dB increase in sound level, would generally
be perceived as barely detectable.”
40 See Appendix B-1-4 Noise and Vibration Comparative Analysis Report
Churchill Avenue
47
With the Closure plus Mitigations alternative, no temporary railroad track (“shoofly”) will be
required. With the Partial Underpass alternative, a shoofly is likely to be required unless an
alternate construction methodology and sequencing is acceptable to Caltrain. With the Viaduct
alternative, a shoofly is required.
A shoofly track increases the time of construction and the cost of the project.
4.2.2. Additional Considerations
4.2.2.1. Creek/Drainage Impacts
There is no creek in the vicinity of Churchill, so the only considerations are related to drainage
impacts.
The Closure plus Mitigations alternative would require a pump station for the bike/pedestrian
undercrossing. Also, the pump station at Embarcadero Road would require relocation to
accommodate the widening of Alma Street, as proposed in the mitigations.
Similarly, a pump station would be required for the Partial Underpass, to service both its
lowered roadway and proposed bike/pedestrian undercrossing.
The Viaduct alternative would have no significant drainage impacts.
4.2.2.2. Long-Term Maintenance
Long term maintenance involves maintaining additional structures built as part of any proposed
alternatives. These include the above and below-grade rail and roadway structures and also
pumping system facilities that are required for groundwater pumping.
For the Viaduct, the structures that will be built to provide above grade railroad and
embankments will require long term maintenance. Similarly, for the Partial Underpass, the road
and rail-related structural components will also require long term maintenance.
The Closure Alternative options provide for below-ground pedestrian passageways/tunnels.
Also, for the Partial Underpass alternative, the road will be depressed below the railroad
structure to accommodate adequate vehicular clearance. Due to high groundwater conditions in
the area, the pumping facilities and related structures will be required for these alternatives.
Therefore, these alternatives will require long-term maintenance of such pumping facilities and
structures.
4.2.2.3. Utility Relocations
The Viaduct option has minimal impacts to utilities.
For the Closure plus Mitigations option, there could be minor utility relocations due to
Embarcadero/Alma Street improvements. The potential exists for utility relocations due to the
bike/pedestrian undercrossing.
Churchill Avenue
48
The Partial Underpass option would require major utility relocations because of its lowered
roadways.
4.2.2.4. Local Street Circulation Impacts during Construction
Areas in/around the construction areas will be impacted during construction.
For the Closure plus Mitigations option, these would be:
● The path along Palo Alto High School would temporarily be impacted during
construction.
● Temporary night and weekend closures of lanes on Churchill Avenue, Alma Street,
El Camino Real, Oregon Expressway, and Embarcadero Road.
For the Viaduct option:
● Alma Street reduced to one lane in each direction.
● Removal of right turn lane on southbound Alma Street at Churchill Avenue.
● Temporary night and weekend closures of lanes on Alma Street and Churchill Avenue.
For the Partial Underpass option:
● Lane reduction on Alma Street during construction.
● Likely closure of Churchill Avenue throughout the excavation and construction of the
undercrossing and related features.
● Likely closure of Kellogg Avenue for the duration of the bike/pedestrian underpass
construction; residential driveway access from one direction only.
The longer it takes to build any of these projects, the more complicated future construction
impacts will be due to increased traffic and trains.
4.2.2.5. Caltrain Right-of-Way Impact
The City of Palo Alto would need to negotiate with Caltrain if any encroachment into their right of
way is needed and the probability of approval by Caltrain is unknown at this time.
The Closure plus Mitigations option, requires permanent encroachment inside Caltrain’s right-of-
way for the pedestrian/bike ramps for undercrossing Option 1.
The Viaduct option requires no permanent encroachment inside Caltrain’s right-of-way.
However, options of a linear park or dual use under the viaduct would require Caltrain approval.
Churchill Avenue
49
The Partial Underpass design requires permanent encroachment inside Caltrain’s right-of-way
for the pedestrian/bike ramps (to the undercrossing at Kellogg Ave) and for the lanes/shoulders
for southbound Alma Street.
4.2.2.6. Caltrain Design Exceptions Needed
The Closure plus Mitigations and Partial Underpass options do not require any Caltrain design
exceptions. The Viaduct option requires a 1.6% vertical grade, whereas the current maximum
grade allowed by Caltrain design standards is 1%.
4.2.3. Traffic Studies
The traffic impact of the alternatives has been extensively studied by AECOM’s consultant,
Hexagon Transportation Consultants, which built upon results from previous consultants,
TJKM.41 42 Analyses were performed under existing traffic conditions and projected conditions
in 2030. They also examined potential mitigations and their projected effects on level of service
at various intersections.
41 Appendix B-3-1 Final Traffic Study Hexagon
42 Appendix B-3-2 DRAFT Traffic Study- TJKM - Draft Traffic Impact Study Report - Churchill Ave Closure (Aug 2019)
Churchill Avenue
50
Analyses of the Closure plus Mitigations, Viaduct, Partial Underpass options showed results summarized in the tables below:
Churchill Avenue
51
Traffic conditions at the study intersections were evaluated using Level of Service (LOS). Level
of service is a qualitative description of operating conditions ranging from LOS A, or free-flow
conditions with little or no delay, to LOS F, or jammed conditions with excessive delays. The
acceptable LOS in the City of Palo Alto is LOS D or better for signalized and unsignalized
intersections.43
As Table 1 shows, under existing conditions, both the Closure plus Mitigations and the Partial
Underpass options result in improvements at Alma/Churchill from today’s conditions, raising
LOS in the AM and PM from F and E to Cs in the Closure plus Mitigations option, and to B and
C in the Partial Underpass option, respectively. The Viaduct option trails slightly at LOS of Ds
for both AM and PM.
As Table 2 shows, in 2030, when Electrification is completed but if no improvements are made,
the LOS at Alma/Churchill remains an F, but with even more delay, resulting in unclearable
queues. Of the three alternatives, Partial Underpass provides the best LOS, with Closure plus
Mitigations next and Viaduct last. The Viaduct has the worst LOS at Alma/Churchill because it
serves all traffic movements, rather than divert cars to other intersections.
In the Viaduct and Partial Underpass options, some XCAP members noted that if flow were not
impeded by the train crossing, the traffic on Churchill might increase due to induced flow
attracted by the lack of a train crossing, increasing the possibility of traffic backups in the small
section of Churchill between Alma and El Camino. This was not studied by the consultant.
Some XCAP members desired more work should be done in this area, but the consultant
disagreed.
In addition, further studies are desired by XCAP members to examine the impacts and potential
mitigations of bicycle and pedestrian traffic. (see Section 4.3 Recommendations)

4.3. Recommendations
Six XCAP members voted to recommend Closure with mitigations to the City
Council as the preferred alternative for the Churchill grade separation (No votes: Phil Burton,
Keith Reckdahl and Nadia Naik). More information about the Majority and Minority positions is
in the next section.
The mitigations proposed by the consultants are early conceptual designs, not final plans. In a
follow-on motion, XCAP voted for additional mitigations and areas of study if Council selects the
Closure alternative. XCAP voted 7-0-2 (Abstain: Tony Carrasco and Phil Burton) for the
following additional mitigations:
● Mitigations should include the 2016 Bike Project and evaluate impacts to El Camino and
Embarcadero and Embarcadero/Emerson/High Streets and along both sides of
Embarcadero (see: Appendix B-14 Embarcadero and El Camino Rail Corridor Study)
(approved but removed from the Capital Improvement Program due to COVID - has
been pushed out past the 5-year timeline).
● Unofficial student pick-up/drop off locations along Embarcadero slip road and possible
safety mitigations needed if more cars travel on that road.
Churchill Avenue
53
● Embarcadero intersection should be revisited when alternatives for Palo Alto Avenue
and Downtown are selected.
● Lincoln/Kingsley/High/Embarcadero multi-way intersection issue needs to be addressed
to reduce neighborhood through traffic.
● Consider working with Town & Country on reducing congestion on Embarcadero/
El Camino.
● Review proposed Pedestrian overpass over Embarcadero for safety issues (Mitigation A
in Figure 8)
● Consider creating a comprehensive bike/pedestrian connection plan.
● Bike/pedestrian path at Seale before building the Churchill bike/pedestrian to allow safe
crossing during construction (and how that might be used for phasing a closure).
(Note: bike/pedestrian path is consistent with park use and can be done on dedicated
park land).
● Study whether Park Blvd should be reopened between Southgate and Evergreen Park.
Consider testing an opening. Neighborhood outreach is critical.
● Consider mitigations (ex. stairs) for the northwest corner of the Embarcadero grade
separation, where westbound foot traffic (represented by the red arrow) on the north side
of Embarcadero Road travels under the grade separation and then up through
landscaping on the northwest embankment towards Town & Country, with many
continuing to Palo Alto High School by looping across Embarcadero using the
Embarcadero bike/pedestrian bridge adjacent to the railroad tracks (represented by the
yellow arrow).
Churchill Avenue
54
• Consider a traffic signal at North California/Alma to have fewer cars along Churchill and
to provide a signalized left out of Old Palo Alto.
Of the choice between Bike/Pedestrian Option 1 or Option 2 (which fully grade-separates
bikes/pedestrians from both Alma and Caltrain), XCAP voted in a follow-on motion 7-0-2
(Abstain: Tony Carrasco and Phil Burton) for Option 2 with the following general potential
mitigations:
4.3.1.1. Add Bike/Pedestrian Crossing at Seale
● Recommended in the Rail Corridor Plan.
● Adds a bike/pedestrian crossing that can be built while mitigations are being built.
● Would provide a more direct Safe Route to School for Greene and Walter Hays from
West of Alma and for Palo Alto High School from students West of Alma and South of
Churchill.
● Reduces bike traffic on congested California Avenue bike/pedestrian tunnel and on
Churchill tunnel.
● Bikes on the west side of tracks end up on Park Blvd which is a bike path.
● Alternatives for Seale design could be center of the road or property acquisition to create
bike/pedestrian ramps to separate from Alma and tracks.
4.3.1.2. Bike/Pedestrian Option 2
● Explore closing Churchill to cars on the East side between Alma and Emerson - only
homeowners and their guests would use the road. Residents would enter/exit Churchill
from Emerson Street. Explore need and possibility for a turn-around at the end of
resulting cul-de-sac.
● Consider the effect of changes on moving trucks, garbage trucks, emergency vehicles,
etc. on an altered Churchill Avenue block. Consider any traffic implications including any
additional traffic onto Embarcadero.
● Explore use of the area from curb and landscaping between curb and sidewalk on both
sides of Churchill Avenue to enable an increase in width of ramp.
● Explore flatter, wider, taller, and fully lit crossing with increased sightlines. Consider
moving the entry to ramp further back from Alma to decrease ramp grade.
The main reasons the group preferred Option 2 is the increased safety for bikes and
pedestrians resulting from entirely grade separating them from both Alma and the tracks.
In addition, there is no queuing from bikes gathering at a traffic signal, which leads to faster
bike/pedestrian connections, significantly improving east/west connectivity.
Member Burton abstained because he did not support the Closure and Member Carrasco
thought all bike designs needed to be re-conceptualized because both designs were
unacceptable since they have tunnels, and he prefers at-grade bike/pedestrian alternatives.
Churchill Avenue
55
4.4. Majority Position
Six XCAP members voted to recommend the Closure of Churchill for the following reasons for
the following 5 key reasons:
1. Lowest cost option
2. Minimal aesthetic Impacts
3. Minimize construction time
4. Vehicular traffic moved elsewhere can be mitigated
5. Safer experience for bicycle and pedestrians
4.4.1. Lowest Cost Option
Closure with Mitigations is by far the lowest cost option, estimated at $50-65M. The Partial
Underpass option is estimated at $160-200M, and the Viaduct option is estimated at higher still
costs of $300-400M. The likelihood of achieving a funding goal is maximized when the amount
sought is minimized.
The Majority felt that additional expenditure of public funds to further study the Partial
Underpass is not justified since the Partial Underpass is already an expensive alternative that is
unlikely to be improved with additional design iteration. In addition, the Minority’s no vote on
this motion seems rooted more in their support for further study rather than their belief that the
Partial Underpass is actually a superior alternative.
4.4.2. Minimal Aesthetic Impacts
The Closure plus Mitigations option minimizes visual changes of the surroundings. There are
no large structures being constructed. The bike/pedestrian underpass will create a new below
ground structure, although much smaller in visual impact than a structure that serves vehicles.
Proposed mitigations at Embarcadero will result in modifications in lane designations, improved
accommodations for cyclists and pedestrians, and new traffic signals, but do not include the
construction of large structures nor large modifications of existing structures.
On the other hand, both the Viaduct and Partial Underpass options will have much greater
visual impact and resulting controversy.
The Viaduct option will introduce a new above-ground structure that runs for some length,
visible from Embarcadero to some point beyond Churchill Ave. Those who own houses with
their backyards adjacent to the train tracks will experience a structure with a train running on it
over 40 feet in the air. Because of the width of the rail corridor near Churchill, the viaduct would
be constructed only a few feet from property lines, increasing the impact on the nearby
properties.
During construction, there would be additional visual impact with temporary, shoofly tracks
running on Alma Street with Alma Street narrowed down to two lanes, one in each direction.
Churchill Avenue
56
The Partial Underpass, while below ground, would also create a large concrete structure whose
roadways are more complicated than a simple underpass, due to a design that preserves some
of its turns and not others. There would be concrete retaining walls arranged to support the
proposed turning movements and roadways.
During construction, the Partial Underpass would also require temporary shoofly tracks running
on Alma Street, and a subsequent lane reduction on Alma. Both of these changes will result in
visual impacts during construction.
4.4.3. Minimized Construction Time
Along with the Viaduct option, the Closure plus Mitigation option has the least amount of
construction time at approximately 2 years, thus minimizing any disruption to traffic and the
community. In contrast, the construction time for the Partial Underpass is estimated to be
greater at 2.5 to 3 years.
4.4.4. Vehicular Traffic Moved Elsewhere Can Be Mitigated
As previously discussed in the Traffic Studies section in this chapter, the vehicular traffic
diverted to other roadways by the closure of Churchill can be successfully mitigated, if not
improved in service level.
Mitigations were examined by traffic consultant Hexagon at seven different intersections where
traffic was projected to be rerouted. Details of currently proposed mitigations can be found in
Hexagon’s report available in Appendix B-3 Traffic Studies and Presentations - Final Traffic
Study - Hexagon Traffic Consultants.

A summary of projected results of the mitigations, and the affected intersections, is shown in Table 5 45 below:
45 Ibid., Table 5 page 49.
Churchill Avenue
59
XCAP notes the four existing intersections with STOP signs were analyzed in the traffic study.
These intersections were assigned LOS F due to heavy delays experienced on the side streets.
In the above chart, Intersections 2, 3, 6a and 6b change from STOP signs to traffic signals.
Intersection 1 changes from a STOP sign to a right-turn-only STOP sign. The proposed
changes at these intersections indicate improvement to LOS for existing and 2030 traffic
conditions.
4.4.4.1. Alma Street Intersections (No. 1, 2 and 3)
With the closure of Churchill Avenue, some traffic would be rerouted to Embarcadero Road.
However, the connections for some of the turning movements between Alma Street and
Embarcadero Road are circuitous. Traffic from Alma Street that wants to head west on
Embarcadero Road must use Lincoln Avenue to Emerson Street. Due to the close spacing,
intersections 1, 2 and 3 could be mitigated as a group with the following recommendations
(shown in Figure 8).
● Restrict the intersection of Alma Street/Lincoln Street to right-in/right-out only
movements.
● Divert left-turning traffic off of Lincoln Avenue by adding a left-turn lane to the
Embarcadero Road slip ramp to facilitate left-turns onto Alma Street.
● Install traffic signals at the Alma Street/Embarcadero Road slip ramp and Alma
Street/Kingsley Avenue with one controller.
● Install a traffic signal at the Embarcadero Road/Kingsley Avenue intersection to allow
left- turns from Kingsley Street onto westbound Embarcadero Road.
● Provide a 75 to 100-foot left-turn pocket on southbound Alma Street at Kingsley Avenue.
● Provide two northbound travel lanes on northbound Alma Street at Kingsley Avenue.
Providing two northbound travel lanes on Alma Street at Kingsley Avenue would require
widening of the Alma Street bridge over Embarcadero Road, as the existing width of the bridge
can only accommodate three travel lanes on Alma Street. Widening would require extensive
modification or potential replacement of the existing bridge structure. No additional right-of-way
is needed on Alma Street, south of Embarcadero Road.
These improvements would provide a direct connection between Alma Street and Embarcadero
Road. Diverted traffic from southbound Alma Street would not have to use local streets to
access Embarcadero Road. In addition, existing traffic on northbound Alma Street would no
longer have to go around the block (Lincoln to Emerson) to travel west on Embarcadero. This
traffic on Alma would make a right-turn at Kingsley and a left-turn at the proposed traffic signal
at Embarcadero Road.
With the proposed improvements, the analysis shows that intersections 1, 2 and 3 would
operate at acceptable levels of service during the AM and PM peak hours under existing
(see Table 5) and Year 2030 traffic volumes (see Table 6).
Churchill Avenue
60
Note that Figure 8 shows a conceptual design of potential improvements at the Embarcadero Road and Alma Street interchange.
If this project were to be pursued, many design details would need to be worked out with regard to maintaining access to existing
residential driveways on Embarcadero Road, Kingsley Street, High Street, and the Embarcadero slip ramp.
Churchill Avenue
61
4.4.4.2. El Camino Real and Embarcadero Road (Intersection 4)
The analysis showed that at the VTA Congestion Management Program intersection of
El Camino Real/Embarcadero Road, significant traffic impacts would occur due to reassigned
traffic. It is recommended that an additional westbound left-turn lane and a northbound right-
turn lane be provided along with signal optimization at this intersection (see Figure 9). With
these improvements, the intersection of El Camino Real and Embarcadero Road would operate
at acceptable LOS E during both peak hours under existing and Year 2030 traffic volumes.
Churchill Avenue
62
Churchill Avenue
63
4.4.4.3. El Camino Real and Page Mill Road/Oregon Expressway (Intersection 5)
At the VTA Congestion Management Program intersection of El Camino Real/Oregon
Expressway-Page Mill Road, the traffic analysis identified significant traffic impacts due to
reassigned traffic. The report recommended a westbound right-turn lane from Oregon
Expressway to northbound El Camino Real along with optimizing the signal timing (see
Figure 10). With these improvements, the intersection would operate at acceptable levels of
service during the AM and PM peak hours under existing conditions. Under Year 2030 traffic
conditions, the analysis shows that the intersection would continue to operate at unacceptable
LOS F with the proposed improvements. However, the intersection delay during both the AM
and PM peak hours is projected to be lower than the intersection delay without these
improvements.
Churchill Avenue
64
Churchill Avenue
65
4.4.4.4. Alma Street and Oregon Expressway (Intersections 6A and 6B)
The traffic analysis identified significant impacts to the intersections of Alma Street/Oregon
Expressway with the reassignment. The analysis determined that these intersections currently
meet the peak hour signal warrant and recommends traffic signals at both the on and off ramps
(see Figure 11). With the proposed traffic signals at both the ramp locations, the intersections
of Alma Street and Oregon Expressway are projected to operate at acceptable LOS C or better
during both peak hours under existing and Year 2030 traffic conditions.

4.4.4.5. Impacts to University Avenue
According to the Traffic Study: “Due to the existing congestion on University Avenue, trips from
the potential Churchill closure much more likely would be rerouted to Embarcadero Road or
Oregon Expressway. The potential Churchill Avenue closure is not likely to impact traffic
operations along University Avenue.”46
The Minority raised concerns about the Traffic Study, however the Majority feels the work
presented was professional and persuasive and that the mitigations presented will sufficiently
address the impacts highlighted in the report. It was noted by City Staff that Hexagon
Transportation Consultants is the leading resource for work in this area and that their reputation
and experience was what led AECOM and City Staff to engage them to work on this project.
The Minority also believes that further analysis might find a need for additional mitigations,
which might lead to increased costs. The Majority believes this is piling speculation upon
speculation.
4.4.5. A Safer Experience for Cyclists and Pedestrians
The Churchill/Alma intersection experiences a sizable amount of bicycle and pedestrian traffic,
especially during the weekdays. Given the proximity to Palo Alto High School, hundreds of high
school students travel to and from campus through this intersection.47 This intersection also
serves as a connection from points north and Stanford University, for both pedestrians and
cyclists.
As it stands currently, neither auto traffic nor the train are separated from cyclist or pedestrian
traffic. This pattern creates a hazardous condition that has seen many accidents over the
years48, and is only poised to worsen as Caltrain electrifies its trains and they travel faster and,
over time, more often.
By fully separating bicycle and pedestrian traffic from both vehicular traffic and the train, a safer
and more enhanced crossing condition can be created for cyclists and foot traffic in and near
Churchill Ave. Proposed mitigations at Embarcadero and Alma also address shortcomings in
the current bicycle and pedestrian paths there. These should include improvements relating
to the areas around Embarcadero at Alma, including Kingsley, High, and Emerson at
46 Pg. 50 of Appendix B-3 Traffic Studies and Presentations - Final Traffic Study - Hexagon Traffic Consultants
47 Appendix B-3-2 DRAFT Traffic Study- TJKM - Draft Traffic Impact Study Report - Churchill Ave Closure (Aug 2019) page 33:
Through their daily traffic counts, they saw approximately 258 cyclists on the days they gathered data. Note that this count was only

their PM count time.

4.5. Minority Position
Three members of the XCAP (Phil Burton, Keith Reckdahl, Nadia Naik- the “Minority”) did not
support the motion, stating that they wanted additional information that the current traffic study
did not provide, that the Closure of Churchill would inequitably distribute traffic to other
neighborhoods, and that further evaluation of the Partial Underpass should also be explored
before any decisions are made.
4.5.1. Additional Traffic Information Needed
The Traffic Study provided baseline analysis to facilitate decision making, but ultimately, it was
insufficient for the Minority to support a Closure due to the following areas of concern:
● The few east/west traffic crossings in the City are inextricably linked. The relationship of
the future grade separation of Palo Alto Avenue or changes to the existing University
Avenue and Embarcadero grade separations should be part of the analysis.
● The report included intersection LOS but without a network LOS analysis of proposed
mitigations/improvements, making it difficult to understand the queuing effects of these
mitigations on the entire network and whether they create capacity constraints at other
intersections. A network analysis may uncover deficiencies that require additional
mitigations/improvements, increasing costs.
● The report did not evaluate potential delays to public transit or/and school buses from
concentrating more traffic on fewer roadways.
● Bike/Pedestrian mitigations were identified as an area of future study, but the Minority
felt the available traffic information was insufficient.
● Analysis describing network impacts of the proposed mitigations beyond 2030 are
needed- even if that analysis is within certain bands of uncertainty given the long-range
nature of the forecasts. Future scenario analysis should test how sensitive the LOS
forecast predictions are to changes in the input assumptions.
● Specific impacts to school operations were not evaluated because detailed information
from the school district was unavailable, so additional potential traffic or safety
mitigations remain unknown.
The mitigations do not prevent the Closure from relocating Churchill traffic to other
neighborhoods. Rather, the mitigations only attempt to reduce the impacts of the relocated
traffic.

4.5.2. Embarcadero Bridge Concerns
The widening of the Alma Street bridge (part of the existing Embarcadero grade separation) is
needed to mitigate some of the proposed changes. Today, the pinch point created by the
narrow bridge serves to slow the speed of northbound Alma traffic and the impact of its removal
was not addressed.
In addition, the 1936 Embarcadero grade separation could at some point in time need to be
retrofitted or replaced, whether due to future earthquake damage or because it has reached the
end of its useful life. If rebuilt, it is very unlikely that the new grade separation would retain the
current single eastbound lane and limited turning movements. Furthermore, from a network
resiliency standpoint, the City should weigh the removal of an east/west arterial. In particular,
maintaining the Churchill crossing may be necessary to support traffic during any Embarcadero
underpass reconstruction.
4.5.3. Partial Underpass Study
As described in the main report, significant iteration of the Partial Underpass design was cut
short and key stakeholders, particularly from the school and bike community, weren’t able to
fully participate in design iterations. The Minority’s concerns have been folded into the
upcoming Areas of Future Study section but represent key areas of deficiencies of the
incomplete design iteration. If, with full participation from key stakeholders, an agreeable design
could be achieved, the Partial Underpass could be a viable compromise addressing the issues
of geographic equity. Alternatively, if after full exploration, the Partial Underpass proved
infeasible, it could bolster community support for the Closure.
4.5.4. Irreversible Nature of the Decision
The railroad on the Peninsula has historically closed existing at-grade crossings, not re-opened
or created new ones. Since today’s CPUC is unlikely to grant a reversal, the decision to close
Churchill should only be made after careful review of as many foreseeable issues as possible.
4.6. Areas for Future Study
XCAP members noted potential areas for future exploration. These are:
4.6.1. Churchill Closure with Mitigations
1. The following suggestions were made:
a. Mitigations should include the 2016 Bike Project and evaluate impacts to El Camino and
Embarcadero and Embarcadero/Emerson/High Streets and along both sides of
Embarcadero (see: Appendix B-14 Embarcadero and El Camino Corridor Improvement
Study Aug 2016) (approved but removed from the Capital Improvement Program due to
COVID - has been pushed out past the 5-year timeline).
b. Unofficial student pick-up/drop off locations along Embarcadero slip road and possible
safety mitigations needed if more cars travel on that road.
c. Embarcadero intersection should be revisited when alternatives for Palo Alto Avenue
and Downtown are selected.
Churchill Avenue
70
d. Lincoln/Kingsley/High/Embarcadero multi-way intersection issue needs to be addressed
to reduce neighborhood through traffic.
e. Consider working with Town & Country on reducing congestion on Embarcadero/
El Camino.
f. Review proposed Pedestrian overpass over Embarcadero for safety issues.
g. Consider creating a comprehensive bike/pedestrian connection plan.
h. Bike/Pedestrian path at Seale before building the Churchill Bike/Pedestrian to allow safe
crossing during construction (and how that might be used for phasing a closure). (Note:
bike/pedestrian path is consistent with park use and can be done on dedicated park
land).
i. Study whether Park Blvd should be reopened between Southgate and Evergreen Park.
Consider testing an opening. Neighborhood outreach is critical.
j. Consider mitigations (ex. stairs) for the northwest corner of the Embarcadero grade
separation, where westbound foot traffic (represented by the red arrow) on the north side
of Embarcadero Road travels under the grade separation and then up through
landscaping on the northwest embankment towards Town & Country, with many
continuing to Palo Alto High School by looping across Embarcadero using the
Embarcadero bike/pedestrian bridge adjacent to the railroad tracks (represented by the
yellow arrow).
k. Consider a traffic signal at North California/Alma to have fewer cars along Churchill and
to provide a signalized left out of Old Palo Alto.
2. Additional bike/pedestrian crossing mitigation future study areas.
a. Add bike/pedestrian crossing at Seale.
i. Recommended in the Rail Corridor Plan.
ii. Adds a bike/pedestrian crossing that can be built while mitigations are being built.
iii. Would provide a more direct Safe Route to School for Greene and Walter Hays
from West of Alma and for Palo Alto High School from students West of Alma
and South of Churchill.
iv. Reduces bike traffic on congested California Avenue bike/pedestrian tunnel and
on Churchill tunnel.
v. Bikes on the west side of tracks end up on Park Blvd which is a bike path.
vi. Alternatives for Seale design could be center of the road or property acquisition
to create bike/pedestrian ramps to separate from Alma and tracks.
b. Bike Option 2
i. Explore closing Churchill to cars on the East side between Alma and Emerson -
only homeowners and their guests would use the road. Residents would
enter/exit Churchill from Emerson Street. Explore need and possibility for a
turnaround at the end of resulting cul-de-sac.
Churchill Avenue
71
ii. Consider the effect of changes on moving trucks, garbage trucks, emergency
vehicles, etc. on an altered Churchill Avenue block. Consider any traffic
implications including any additional traffic onto Embarcadero.
iii. Explore use of the area from curb and landscaping between curb and sidewalk
on both sides of Churchill Avenue to enable an increase in width of ramp.
iv. Explore flatter, wider, taller, and fully lit crossing with increased sightlines.
Consider moving the entry to ramp further back from Alma to decrease ramp
grade.
3. Analyze the impacts of widening the Alma Street bridge on the overall traffic network and
any necessary mitigations.
4. Consider a cost-benefit analysis of whether the Embarcadero grade separation might
eventually need replacement, whether opportunities exist to improve all turn movements if
replaced, and what impact that has on other east/west arterials and their planned
improvements since closure of Churchill could impact network resiliency.
5. Consider impacts of any roadway modifications to east/west travel, particularly with regard
to decisions made on the future Downtown coordinated Area Plan and the Palo Alto Avenue
crossing.
6. Given the impacts to the overall project timelines from COVID, it is expected that an updated
Traffic study eventually will be needed. The following suggestions are areas of future study
that could be included:
● Expand Traffic Study to include impacts beyond 2030 - Analysis describing network
impacts of the proposed mitigations beyond 2030 are needed. Given the uncertainty of
long-range forecasts, analysis with certain confidence bands and future scenario
analysis should test how sensitive the LOS forecast predictions are to changes in the
input assumptions.
● Perform network LOS analysis of proposed mitigations and improvements to understand
the queuing effects of these mitigations and whether they create capacity constraints at
other intersections.
● Consider potential delays to public transit or/and school buses that may result from
concentrating more traffic on fewer roadways.
4.6.2. Churchill Partial Underpass
If the Council would like to pursue the Partial Underpass, further design review should seek to
reduce the underpass cost, size, and encroachment within the Caltrain ROW. Some ideas
include:
● Explore whether raising the rail tracks by a few feet, which would reduce both the
underpass depth and length along both Churchill and Embarcadero, potentially reducing
property impacts and cost and improving visual appearances.
● Explore ideas to reduce the width of Churchill’s lanes/shoulders to reduce the underpass
width, further reducing excavation and construction costs.
Churchill Avenue
72
● Explore whether it is possible to design a bike/pedestrian crossing closer to Churchill
itself to address circuitousness created by having the bike/pedestrian crossing at either
Kellogg or Seale.
● Work with Caltrain to address encroachment on their ROW.
● Model whether the building of a Partial Underpass could cause auto traffic inducement.
4.6.3. Churchill Viaduct
If the Council would like to pursue the Viaduct, some ideas for areas of further study include:
● Consider the exploration into a viaduct over Embarcadero, but with a reduced and
diminishing height at the Churchill intersection to allow for a Homer-like bike/pedestrian
underpass.
● Model whether building a Viaduct at Churchill would induce auto traffic.
4.6.4. Future Outreach Opportunities
Although the City did some outreach, the distractions of the pandemic may have inhibited the
community’s ability to fully participate in XCAP’s Churchill designs and eventual decision.
Palo Alto has an incredibly rich bike/pedestrian community, and collaboration with community
members should be encouraged to leverage their insights to improve all future designs. XCAP
recommends that further outreach about the Churchill crossing should include the following
groups:
● Palo Alto Unified School District (PAUSD)
● Palo Alto High Students
● Palo Alto High School PTSA
● Palo Alto Council of Parent Teacher Associations - PTAC
● Safe Routes to School Team (SRTS)
● City/School traffic liaison committee
● Palo Alto Pedestrian and Bicycle Committee (PABAC) and other bicycle-advocacy
organizations
● Stanford University
● Town & Country Village management and merchants
● Palo Alto Chamber of Commerce
● Palo Alto Neighborhoods (PAN)
● Adjacent neighborhood associations
● Castilleja school administration and students
● Caltrain
● Union Pacific Railroad (or future short line operator)
Meadow and Charleston Options

5. Meadow and Charleston Options
5.1. Summary of Actions
The members of XCAP agree that grade separations are important to the community and that
Meadow Drive and Charleston Road are important transportation corridors for bicycles,
pedestrians, and cars that must be separated from the rails.
Throughout the process, XCAP studied each alternative, and gathered useful information for
each option. Importantly, XCAP also championed a new option, the underpass, which was
suggested by a citizen and which many hoped would represent a useful compromise between
the alternatives that had already been presented.
When asked to recommend a single solution for each of Meadow Drive and Charleston Road,
XCAP unanimously agreed they could not decide with the current information available. No
alternative received the support of more than three members. In the end, multiple individual
members championed the hybrid, trench, viaduct, and underpass options for different reasons.
There was, however, unanimous consensus to remove the two South Palo Alto Tunnel
alternatives from further consideration.
To be able to select a preferred alternative, there are a series of important questions to answer.
Larger questions, such as the need for four-track segments in Palo Alto and the ability of
Palo Alto to participate in a corridor-wide grade separation study for the entire CalTrain system,
have been discussed elsewhere in this report. Other more specific questions about the
individual alternatives are enumerated below.
The XCAP hopes that this section will contain a clear enough presentation of the options that
policymakers will be able to gather some of the missing information and make a decision.
5.2. Options Considered by XCAP
At the start of the XCAP process, XCAP members were presented with four options for the
Meadow and Charleston grade crossings.
● Tunnel, in which the train enters an underground tunnel long enough to pass beneath
both Meadow and Charleston.
● Viaduct, in which the train passes over the road on an elevated structure, and the road
remains at its current level.
● Hybrid, in which the train is raised on a berm and the road is lowered into a shallow
trench so that vehicles and pedestrians pass underneath the train tracks.
● Trench, in which the train is depressed below the ground in an open trench and the road
remains at its current level, crossing the trench on a bridge.
Meadow and Charleston Options
74
In addition, during the XCAP process the committee sought additional ideas from residents.
A citizen proposed the underpass design, which XCAP took to City Council and which was
approved for further study.
In this new underpass design, trains stay at grade level, and cars, bicycles, and pedestrians
pass underneath. The underpass design also includes a traffic circle, creating an intersection in
which cars can make certain turning movements without the need for a traffic light. More
information about the development of the underpass design is available in Appendix C-1 History
of Meadow-Charleston Underpass Alternative.
Fact Sheets, for all Meadow-Charleston Alternatives are available in Appendix A-1 Fact Sheets,
renderings are available in Appendix A-2 Renderings and Plans and animations and exhibits
used for the Virtual Town Hall are available in Appendix A-5 Links to Animations and Virtual
Town Hall.
5.2.1. Tunnel Options
5.2.1.1. Citywide Tunnel (removed prior to XCAP)
In May 2018, the City Council voted to study a Citywide tunnel that ran within the limits of
Palo Alto. The term “Citywide” was/is a misnomer because the plans as designed were for a
tunnel originating at the University Avenue Station and ending just before San Antonio Road.
Early design work showed significant property impacts associated with this alternative. The
Citywide tunnel was removed from consideration by the City Council on May 13, 2019, prior to
the formation of the XCAP in June 2019.
The profile and typical section drawings can be found Appendix A-6 Discarded Alternatives and
the animation can be found at: https://vimeo.com/325481133/e987af4a60
5.2.1.2. South Palo Alto Tunnels with and Without Freight
Due to significant community interest in an underground alternative, the City Council added two
tunnel alternatives for South Palo Alto. In one option, freight would travel in the same tunnel as
Caltrain under Meadow and Charleston. In the other, a Caltrain-only tunnel is constructed
under Meadow and Charleston and the three freight trains a day remain on a pair of surface
tracks. (As described in Chapter 2, freight requires a flatter vertical grade than passenger
trains. In theory, this could allow the Caltrain trains to use steeper vertical grades to tunnel
underneath the creeks with a smaller impact and possibly lower costs.)

Ultimately, the South Palo Alto tunnel alternatives were estimated by AECOM as costing
roughly between $1.173 billion and $1.827 billion. Because of this high cost, significant
construction time and other drawbacks, XCAP unanimously decided to remove the
tunnel alternatives from further deliberation.
Fact Sheets, for the South Palo Alto Tunnel Alternatives are available in Appendix A-1 Fact
Sheets, renderings are available in Appendix A-2 Renderings and Plans and animations and
exhibits used for the Virtual Town Hall are available in Appendix A-5 Links to Animations and
Virtual Town Hall.
5.2.2. Viaduct
The viaduct option raises the tracks over both Meadow and Charleston Roads on an elevated
concrete structure. As designed by AECOM, the bottom of the structure is about 20 feet above
ground as it crosses both roads and in between the roads, it rises at about a 1.4 percent grade
to meet that height on both ends. The viaduct would be topped by six-foot sound wall barriers,
plus an overhead contact system for electrical power that reaches a height of about 30 feet
above the tracks.

5.2.3. Hybrid
The hybrid option raises the tracks on an earthen berm with a maximum height of 15 feet, and
simultaneously lowers the roadway of both Meadow and Charleston Roads so that vehicles can
pass under the tracks with the appropriate clearance. The berm would be topped by a six-foot
sound wall barrier, and an overhead contact system for electrical power would rise about 30 feet
above the track height.

5.2.4. Trench
The trench option lowers the track below the current level into a 37-foot-deep trench that is wide
enough for two tracks. Trains enter and exit the trench via a slope with maximum two percent
grade and stay in the trench as they pass below both Meadow and Charleston Roads. Road,
pedestrian, and bicycle traffic would cross the tracks at the current grade level on bridges that
span the trench. There would be a permanent 12-foot fence surrounding the trench, potentially
with higher fencing in the areas where the train is descending into the trench to protect people
from the electrified catenary wires.

5.2.5. Underpass
The underpass design lowers the roadway below the level of the tracks, leaving the rails at their current level. In order to minimize
acquisition of private property, and in order to maximize traffic flow, traffic at Charleston Road is routed to a roundabout, creating a
form of a “continuous-flow intersection” in which cars can make all turning movements, in many cases without having to wait at a
traffic light.

As currently designed by AECOM, this design proposes a more traditional underpass at Meadow Road that does not include the
roundabout option. This was done in part because Meadow Drive is narrower than Charleston, leaving less room for a roundabout
without greater property impacts.

5.3. Choosing Between the Alternatives
The XCAP did not reach a consensus or a majority opinion on the remaining options. However,
each option had some proponents, and some detractors.
Note that the alternatives chosen for Meadow Dr. and Charleston Rd. must be the same when
considering a Tunnel, Viaduct, or Trench, since the distance between them is too short to have,
for example, a Viaduct at Meadow and Trench at Charleston. In the case of the Underpass and
the Hybrid, it is possible to mix the two alternatives. For more information, see Appendix A-4-4
Memo from Office of Transportation Re: Mixing of Underpass and Hybrid Grade Separation
alternatives.
5.3.1. Tunnel
Proponents of the tunnel praised its ability to hide the trains completely from view for part of the
rail corridor. As previously described, XCAP voted to remove tunnel options from future
consideration and this section will not discuss it further.
5.3.2. Viaduct
Proponents of the viaduct argue that the viaduct can be constructed in the least time and with
the least disruption, that it may actually move the tracks further from the nearest homes than
other alternatives, and that land under the viaduct could possibly be used for public benefit
make it worth considering despite the extra cost.
Detractors are concerned with the visual impact of a large concrete structure in what is mostly a
residential area and its possible impact on residents’ privacy.
5.3.3. Hybrid
Proponents of the hybrid cite the fact that it would be the least expensive to construct (half the
cost of the viaduct and underpass and possibly one-quarter the cost of the trench). It also can
be constructed without asking for an exception from Caltrain for a grade greater than one
percent.
Detractors share the same concerns of viaduct detractors in that the hybrid will make trains
more visible and create large berms at Meadow and Charleston.
5.3.4. Trench
Proponents of the trench argue that lowering the trains reduces their impact on the surrounding
residential communities by largely hiding them from view, that some areas over the trench might
be used for public benefit, and that the trench leaves bicycles and pedestrians at grade.
Meadow and Charleston Options
97
Detractors are concerned with the potential for the trench to be the most expensive of the
remaining alternatives, and with the potential for the trench to affect the creeks and
groundwater.
5.3.5. Underpass
Proponents of the underpass argue that, if more work is done to refine the design, the
underpass has the advantage of not raising or lowering the rails and may even reduce traffic
congestion because it makes more traffic movement possible without the need for a traffic light.
It also is the only option that easily supports separate, dedicated bicycle lanes. The underpass
also requires no design exceptions from Caltrain.
Detractors are concerned that the current design has the most severe property impacts of all the
alternatives.
5.4. Detailed Comparison of the Options
5.4.1. City Council-Adopted Criteria
This section distinguishes the alternatives based on Council-adopted criteria. Note that the
criteria are slightly duplicative in places and will be addressed as appropriate.
5.4.1.1. Facilitate Movement across the Corridor for All Modes of transportation
All of the options separate rail and road traffic, however, the underpass, as currently designed,
does not allow for all vehicle movements at all intersections. (Bicyclists and pedestrians are
addressed separately below.)
5.4.1.2. Reduce Delay and Congestion for Vehicular Traffic at Rail Crossings
All of the options reduce the delays caused by the lowering of the crossing gates to allow for
trains to pass. For cars traveling east/west on Charleston across Alma, the underpass further
reduces traffic delays because no traffic lights are required to traverse the Charleston Road
intersection. The underpass also separates bicycles from cars, which further reduces
congestion by reducing delays from mixed modes.
5.4.1.3. Provide Clear, Safe Routes for Pedestrians and Cyclists Crossing the Rail
Corridor, Separate from Vehicles
The underpass option is the only option that includes separate, dedicated bicycle and
pedestrian lanes providing a grade separation from both the train and Alma. For all of the other
alternatives, (viaduct, trench, tunnel, and hybrid) bicycles and pedestrians would operate as
they do today. In general, all of the options presented here would benefit from further careful
refinement of the exact routes for bicycles (See Chapter 7 Recommendations and Lessons
Learned for more details).
Meadow and Charleston Options
98
5.4.1.4. Support Continued Rail Operations and Caltrain Service Improvements
None of the options are significantly different in their support for Caltrain operation and
improvement once the project is complete. However, XCAP does not have enough information
to assess Caltrain’s need for four-track segments in Palo Alto. XCAP also does not have
enough information to determine the relative complexity of converting any of the options from
two to four tracks if Caltrain requires this.
(For information about impacts on Caltrain during construction, see Section 5.4.1.10, Minimize
Disruption and Duration of Construction below.)
5.4.1.5. Finance with Feasible Funding Sources
AECOM’s preliminary engineering produced approximate cost estimates.
While not definitive, these cost estimates provide the following conclusions:
● The viaduct and underpass would cost roughly twice as much as the hybrid.
● The trench would cost roughly twice as much as the viaduct and underpass, or four
times the cost of the hybrid.
● The South Palo Alto tunnel options would cost twice again as much as the trench.
Alternative Cost Estimate (Low) Cost Estimate (High)
Hybrid $190 million $230 million
Underpass $340 million $420 million
Viaduct $400 million $500 million
Trench $800 million $950 million
Tunnel with surface freight $1,173 million $1,759 million
Tunnel including freight $1,218 million $1,827 million
In addition to funding from Measure B, additional funding from local, county, state or federal
sources will likely be needed to fund the projects due to their high costs. (See Section 2.8
Funding)
Opinions in the community and on XCAP differed on the accuracy of the cost estimates
provided by AECOM. Further research on costs is recommended if cost will be a major factor in
the Council’s final decisions. Policymakers should note that none of the cost estimates from
AECOM are for four track alternatives and it is unclear what the cost comparisons across
alternatives might be if four tracks were needed. It should be noted that the Underpass design,
Meadow and Charleston Options
99
which does not move the train tracks at all, may be the least impacted, but further study would
be required to be sure this is accurate.
5.4.1.6. Minimize Right-of-Way Acquisition (Private Property Only)
The underpass, as currently designed, would require the acquisition of several parcels near the
affected intersections. Some other options have smaller property impacts: the hybrid may
require modifications of several driveways, and construction of the trench may affect how some
neighbors on the west side of Alma can use the underground space in their backyard for
swimming pools and trees due to the potential need for ground anchors to support the trench
walls.
5.4.1.7. Reduce Rail Noise and Vibration
Generally, the noise impact of all of the solutions is likely to be about the same, with the
exception that the hybrid will measurably reduce road noise from Alma Street for some areas.
In addition, the viaduct provides the most significant vibration reduction. Specifically, the
AECOM noise report predicts a “significant reduction” in vibration for the viaduct, a “slight
reduction” for the trench and hybrid, and “no change” for the underpass.
In general, noise concerns were raised by many who spoke in public forums and contacted
XCAP. More detailed information is available in the Noise Section 5.7.2.
5.4.1.8. Maintain Access to Neighborhoods, Parks, and Schools along the Corridor,
while Reducing Regional Traffic on Neighborhood Streets
Most of the options would not introduce any changes in these areas. However, the underpass,
which as currently designed does not allow all turning movements at Meadow, may increase
“cut-through” traffic on nearby residential streets. Similarly, southbound Alma traffic destined for
El Camino may choose to turn on Meadow to avoid the Charleston light and roundabout.
However, the Hexagon traffic study indicates that these turning motions currently involve a small
number of vehicles.
5.4.1.9. Minimize Visual Changes along the Corridor
The underpass alternative would not move the train tracks. So, there would be no visual
change to the rail corridor from today’s current conditions, although there would be visual
changes along additional parts of Charleston and Meadow Roads.
The trench alternative lowers the train but will require fencing (similar to the fencing today on
the east side of the tracks along Alma) on both sides of the tracks, with some potentially higher
fencing in the sections where the train is transitioning deeper into the trench.
The hybrid option would raise the train tracks on a berm about 15 feet high and would create
an earthen or concrete wall along the length of the right of way except at intersections. The
viaduct would raise the trains 20 feet in the air compared to today’s existing tracks, but it would
Meadow and Charleston Options
100
keep open space beneath the tracks. As currently designed, this would move the tracks closer
to Alma Street, and farther from homes, than any of the other alternatives. The added height of
both of these options in the vicinity of single-story homes could make the trains more visible
than they are today.
5.4.1.10. Minimize Disruption and Duration of Construction
Caltrain and freight operations must continue throughout the construction of grade separations.
In order to accommodate these operations, temporary, electrified passing tracks (known as
shoofly tracks) must be built for all of the alternatives except the Viaduct. The Viaduct can be
constructed alongside the existing tracks without the need for a temporary track, which is why it
is the alternative with the shortest construction duration (2 years) and requiring minimal road
closures. Other options would potentially take between four and six years to construct, with
either lane reductions on Alma Street or the temporary closure of Meadow and Charleston
roads during parts of construction.
The noise report, mentioned previously, also addresses noise and vibration during construction.
The report predicts “moderate” construction noise impacts for the viaduct, “moderate to severe”
noise impacts for the hybrid, and “severe” noise impacts for the trench and underpass.
5.4.2. Additional Considerations
This section describes other potential issues which affect Charleston/Meadow alternatives.
5.4.2.1. Creek/Drainage Impacts
The trench and possibly tunnel options require diversion of Adobe Creek and either Barron or
Matadero Creeks and the construction of a siphon, pump station, or both to get the creek water
and wildlife safely across the tracks. The Hybrid and Underpass options do not impact the
creeks but will likely require pumping stations to prevent flooding on the depressed sections of
roadway.
5.4.2.2. Long-Term Maintenance
It is likely that the options that require pumping stations will require more maintenance than the
others, but other than that XCAP does not have enough information to fully understand the long-
term maintenance requirements of these options and the quantification and magnitude of costs
relative to normal expenditures.
5.4.2.3. Utility Relocations
Roadways and rail right of ways are typically utility corridors. Utility conflicts with the myriad of
existing water, gas, sanitary sewer, electric, telephone/cable/communications, fiber optic
facilities in the project vicinity could have significant impacts. Sewer systems are often gravity
systems and may require pumps.
Meadow and Charleston Options
101
Grade separation projects could offer an opportunity to modernize aging utilities or upgrade
utilities (Fiber to the Premises Plan, for example). All of the options require some amount of
utility relocations. The degree of impacts and any potential long term maintenance costs are
unknown and further study will be needed as designs continue to progress.
5.4.2.4. Railroad Operation Impacts during Construction
All of the options but the Viaduct require the construction of a “shoofly” track to allow Caltrain
options during construction.
5.4.2.5. Local Street Circulation Impacts during Construction
This is covered above in Section 5.4.1.10 Minimize disruption and duration of construction.
5.4.2.6. Caltrain Right-of-Way Impact
None of the Charleston/Meadow options will have a significant impact on Caltrain’s right-of-way,
although limited right-of-way use could improve the underpass design. For example, right-of-
way use for the underpass ramp from eastbound Charleston to south Alma would shift the
roadway to west, allowing a wider sidewalk and/or less property acquisition on the east side
of Alma.
5.4.2.7. Caltrain Design Exceptions Needed
The Trench and Tunnel options require an exception from Caltrain for a 2% grade on the
tracks, and the Viaduct requires an exception for a 1.4% grade. The underpass does not
require a grade exception, although Caltrain approval would be needed for non-traditional
construction techniques (such as jacked-box construction) to reduce construction time and cost.
5.5. Pros and Cons of Individual Alternatives
5.5.1. Viaduct
5.5.1.1. Viaduct Advantages
● No acquisition of private property is required.
● All existing traffic movements at both Meadow and Charleston are possible.
● Traffic is not diverted into residential neighborhoods.
● It does not impact the creeks and will not require any new drainage systems.
● Land under the viaduct could potentially be used as public space. Other train viaduct
projects around the world, such as in Melbourne, Australia, have successfully created
new public amenities as part of viaduct construction.
● The proposed design by AECOM places the viaduct about 40 feet farther from homes on
Park Boulevard than the current location of the tracks. This would reduce the visual
impact, assuming that Caltrain allows the viaduct to be moved to this outer section of the
right-of-way.
Meadow and Charleston Options
102
● No shoo-fly tracks are necessary.
● It has the shortest construction timeline of all the alternatives.
● Some other alternatives require a 2% Caltrain design exception, whereas a viaduct only
requires 1.4% Caltrain design exception.
● Minimal road closures (only nights and weekends) are required during construction.
● If four tracks are necessary, this alternative likely does not preclude the addition of two
passing tracks, although the additional tracks would be placed close to the neighboring
properties.
● The viaduct will not necessarily produce any more noise than other alternatives.
● The viaduct may significantly reduce the amount of vibrations felt by residents and
businesses near the tracks.
5.5.1.2. Viaduct Disadvantages
● It is the tallest alternative with greatest perceived visual impact.
● There are potential privacy concerns given the height of the viaduct relative to the
homes adjacent to the tracks on Park Blvd, some of which are part of a single-story
overlay zone.
● The viaduct is less expensive than a trench, but more expensive than the hybrid or
underpass options.
● The viaduct design keeps bicycle and pedestrian traffic similar to today; it does not
degrade bicycle/pedestrian safety, but it also does not improve it.
5.5.2. Hybrid
5.5.2.1. Hybrid Advantages
● Pedestrians, cyclists, and vehicle traffic are all separated from rail traffic.
● All current turning movements at both intersections are retained in this design. No traffic
diversions are necessary.
● Maximum height of tracks is 15’ versus 20’ height for a viaduct.
● Use of solid berm under raised tracks versus structure for viaduct will mitigate sound
transmission up to 12 dBA for homes on the west side of the tracks by reducing road
noise from Alma Street.
● No full property acquisitions are necessary, although some driveway modifications are
required.
● No Caltrain right of way is required to construct this alternative.
● Lowest cost estimate of all Meadow-Charleston alternatives.
● If a four-track system is needed for HSR, the hybrid may not preclude the ability to add
two passing tracks.
Meadow and Charleston Options
103
5.5.2.2. Hybrid Disadvantages
● Water pumps are required for lowered sections of roadway. Their location needs to be
determined and additional maintenance costs need to be quantified.
● Shoofly tracks are required during construction, with negative traffic impacts on
Alma Street due to lane closures for several years.
● There will be a noticeable visual impact due to an elevated rail on an earthen berm,
creating a wall for the length of the structure except at intersections.
● The earthen berm could be perceived as dividing the city/neighborhoods.
● There are potential privacy concerns given the height of the hybrid relative to the homes
adjacent to the tracks on Park Blvd, some of which are part of a single-story overlay
zone.
● Bikes (particularly young riders) traveling eastbound head downhill towards the
intersection could have limited sight distance and may need to stop abruptly to wait for
traffic signals.
5.5.3. Trench
5.5.3.1. Trench Advantages
● Enables at-grade crossings over the train tracks for vehicles, pedestrians, and cyclists to
reduce the accident and provide better traffic circulation without delay.
● Improves the visual aspects of the neighborhood as the train (including electrical pole
and wires) will be hidden from view.
● A “lid” on part of the trench could potentially be used as a park or a playground,
therefore improving neighborhood look and feel. However, this would require Caltrain
approval, additional engineering work, and higher cost.
● No acquisition of private properties is required.
5.5.3.2. Trench Disadvantages
● If four tracks are needed, the two-track trench as designed would preclude the possibility
of adding two more tracks in the future except at great expense.
● Temporary shoofly tracks are required.
● Long construction duration: AECOM estimates a construction timeline of 5-6 years.
● High construction price: AECOM’s estimates are $800M to $950M (2025 dollars
estimates).
● Technical challenges on dealing with both creeks: AECOM’s design requires diversion
of Adobe and Barron Creeks resulting in the need for pump stations. With the pump
stations, there will be potential risks to train operations from flooding. Other creek
options such as siphons also have technical challenges.
Meadow and Charleston Options
104
● Unclear how much of an impact a trench 30-40 feet deep will have on the surrounding
groundwater. The AECOM design includes groundwater pumping, which likely would
lower surrounding groundwater levels. The design could eliminate groundwater
pumping by sealing the trench, but even that may disrupt the groundwater flow.
● A non-standard grade of 2% is required.
● The trench design keeps bicycle and pedestrian traffic similar to today; it does not
degrade bicycle/pedestrian safety, but it also does not improve it.
5.5.4. Underpass
5.5.4.1. Underpass Advantages
As described above, among all the alternatives, the AECOM Meadow/Charleston Underpass
was only an initial concept that did not receive sufficient review. As such, the following lists of
pros and cons is a critique of the initial AECOM design meant to inform areas of future study
(see Future Study section).
● Minimal visual impacts without disadvantages of tunnel.
● Bikes/pedestrians are fully grade separated from the four lanes of Alma Street.
● Design serves to improve vehicular traffic flow while avoiding traffic inducement. Traffic
Study shows Underpass design has better LOS than other alternatives
● Design creates a loop system for bikes/pedestrians - with direct connections to frequent
locations. Some trips would be more direct, for others less, but would avoid a lengthy
traffic signal at Alma.
● Lower construction duration and impacts than trench and tunnel.
● Potentially lower cost than tunnel, trench, and viaduct.
5.5.4.2. Underpass Disadvantages
● As currently designed, this option requires significant property acquisitions. There is
strong community opposition to any potential property acquisitions.
● Complex navigation for bikes and cars.
● Limits certain traffic movements.
● Potential minor traffic diversion through neighborhood (page 26/27 of Final Traffic
Report).
● Concerns about accessibility of driveways on arterials being impacted by additional
traffic.
Meadow and Charleston Options
105
5.6. Priority Areas for Future Study
Choices for the Meadow and Charleston crossings share a set of areas for future study areas
with other sections of this report. Specifically:
● CalTrain advocacy and coordination with a corridor-wide grade separation project
● The presence or absence of four-track segments in South Palo Alto
● Formalizing impact from the community on bicycle and pedestrian issues
● Geotechnical and groundwater analysis
5.6.1. Geotechnical and Groundwater Analysis
The hybrid, trench, and underpass alternatives all require significant excavation. The XCAP
recommends that the council authorize a preliminary geotechnical and ground water analysis.
This information is needed to help refine the cost estimates and provide insight about alternative
construction methods.
5.6.2. Construction Methods
A technology referred to as “jacked box construction,” in which a precast box is pushed into
place, was identified early on as a potential construction method that could be used to avoid
needing electrified shoofly tracks which are expensive, disruptive and add significantly to
construction time. This method was most recently used50 in Florida and Long Island, NY,
resulting in significantly shorter construction time.
A design goal of the XCAP Underpass Concept was to avoid moving the tracks at all (to reduce
cost, construction time and complexity), but without further geotechnical studies, it is not
possible to determine whether this approach is feasible. Caltrain has indicated interest in
understanding more about construction methods that could avoid the need to construct
electrified shoofly tracks through its Corridor Wide study.
XCAP recommends that Staff provide Caltrain the materials gathered through XCAP and
through public comment related to Jacked Box construction for incorporation into Caltrain’s
Corridor Wide Grade Separation Study.
5.6.3. Viaduct: Specific Study Areas
● More detailed plans. The plans that XCAP has for the viaduct include very few
dimensions, so it is hard to ascertain the visual and other impacts of the proposal. In
addition, none of the plans describe the actual structure and shape of the viaduct. This
would go a long way to helping the community better understand what is actually being
proposed.

story.html
Meadow and Charleston Options
106
● More renderings. XCAP has a few images that show the proposed visual impacts of the
viaduct, but not nearly enough considering that the visual impacts are a main
disadvantage of this option.
● A plan showing where the viaduct would be placed to one foot of accuracy.
● Cross sections every 100'-200' from east of Alma Street to the first property on
Park Avenue, shown with potential screening and sound mitigations.
● A formal accounting of how many properties are affected by the viaduct showing a
longitudinal profile of the track elevation compared to the lots affected.
● Additional noise analysis, including a prediction for noise levels farther from the tracks.
A large number of commenters are concerned that the viaduct, because of its height, will
transmit sound farther than the other alternatives and they would like to understand what
this will actually mean.
● A partnership with a landscape architect and/or urban designer is highly recommended
to ensure that the planned structure and any improvements to the land under the
structure are compatible with the look and feel of the rest of the city.
5.6.3.1. Usable Space
Policymakers should consider the possibility that negotiating with Caltrain could provide the City
with a new opportunity – space at ground level that would previously have been occupied by
train tracks would now be vacant. What sorts of things could the city do with that space?
For instance, a large transit project in Melbourne that included many viaducts51 included public
art, parks, gardens, and other facilities in the space opened up by the construction project.
Similarly, the Ohlone Greenway in the East Bay runs partially on land adjacent to a BART
viaduct.52 Similar designs could be an asset to Palo Alto.
The XCAP recommends further study of potential uses of this space be considered as part of
Caltrain’s Corridor-wide grade separation study. Caltrain may have multiple places where cities
would be asking for similar use permits, and they could consider acceptable public uses as part
of their study.
5.6.3.2. Maintenance
If the viaduct concept is pursued further, XCAP recommends that Staff work with Caltrain to
negotiate the long-term maintenance of this land after construction and in perpetuity to maintain
attractive landscaping. Standards related to this issue, including whether fencing will be needed
should be clarified and included in formal agreements. More information related to fencing is in
Chapter 6.

Meadow and Charleston Options
107
5.6.3.3. Visual Design and Privacy
To improve the visual appeal of a viaduct, XCAP would recommend consideration of a variety of
construction materials, shapes, and surface treatments that could enhance how a viaduct fits
into the landscape. Any viaduct should be designed in close collaboration with the community,
working with landscape and urban designers, to build community support. The use of noise
barriers as a potential way to increase privacy for the homes along the tracks should be
explored.
5.6.4. Hybrid: Specific Study Areas
● Could the maximum track height be lowered to less than 15 feet? How much can the
tracks be lowered before full or partial property acquisitions are required?
● Could there be some partial acquisitions that could enable some advantage in height?
● Which properties would require driveway modifications?
● What sound mitigations can be done and what do they look like?
● What do the bike and pedestrian pathways look like in more detail?
● Can the maximum grade on the bike and pedestrian ramps be lowered to 5% or less?
What is the impact on total ramp length (and possibly properties)?
● What mitigations are possible for eastbound bikes traveling downhill that may have
limited sight and limited stopping distance approaching the Alma intersection?
● If the building of the grade separation increases capacity and induces more traffic, what
additional protections will be necessary to mitigate more bikes sharing the road?
(Example: Will protected bike lanes be needed and how far would they need to extend?)
● Would this design preclude the ability to add two additional tracks for HSR if required?
● Is there enough queuing space for cyclists traveling eastbound towards each
intersection to accommodate those waiting for a traffic signal?
5.6.5. Trench: Specific Study Areas
The trench is desired by many because it removes the train from view, but a trench design
involves significant engineering challenges. It is important for the community and Council to
have realistic expectations: a trench design will not be easy, but it is not impossible. Because
this is such a complicated design, it is critical that the City select a consultant with trench
experience.
The engineering challenges of a Charleston/Meadow trench include the following:
● Because the water table is relatively shallow in the Charleston/Meadow area, the trench
may affect groundwater both during and after construction. This includes the potential of
the groundwater leaking into the trench and the potential for the trench interfering with
the flow of groundwater.
Meadow and Charleston Options
108
● Because both Baron Creek and Matadero Creek are relatively close to Meadow Drive
and Charleston Road, the trench can potentially interfere with the creeks’ water flow.
Any modification to the flow of these creeks requires the approval of Valley Water and
other regulatory agencies.
● The trench walls must be supported to prevent the walls from caving in. Some methods
for providing such support may extend outside of the trench, possibly affecting or
constraining public and/or private property.
● Because trench involves changing the elevation of the tracks, any trench design affects
train operations and thus requires Caltrain approval. In particular, Caltrain must approve
both the track slope and vertical curvature that is used in the trench.
● Like many of the alternatives, the trench involves extensive construction, requiring both
significant budget and a significant construction duration.
Some of these issues are coupled. For example, some approaches that reduce the
trench/creek interference result in a deeper trench, which may increase groundwater impacts.
Additional information is available in Appendix C-3 Concerns with Meadow-Charleston Trench
Design.
5.6.5.1. Possible Trench Design Techniques
Because of the variety of engineering challenges, any successful trench design will require
many iterations. Possible trench-design approaches to consider include:
● The trench must be deep enough to pass below the Charleston and Meadow bridges.
The current design has the rail 30 feet below the road surface; this trench depth could be
reduced by designing bridges with thin decks and providing minimal clearances under
the bridges. Every foot of reduced trench depth reduces the trench length by 100 feet,
thereby reducing construction costs and potentially reducing trench/creek interference.
○ Designers should consider how to reduce bridge-deck thickness, including using
truss bridge design. In particular, a bow-string arch or tied-arch design with a
short height might produce an attractive design that appeals to the community.
● The Hatch Mott McDonald trench design (October 2014) chose to avoid creek impacts
by routing the trench under the creeks, resulting in a longer, deeper trench.
○ This over-the-trench routing is more feasible for the shallow low-flow Barron
Creek, but routing Adobe Creek’s larger flow above the trench would require
significant collaboration with Valley Water.
○ This longer trench could also impact the Caltrain crossover-track section just
north of San Antonio. Like many other things, any crossover-track relocation
would have to be approved by Caltrain.
● Caltrain’s preferred maximum grade (slope) is a 1% grade but grades up to 2% are
allowed with a Caltrain design exception.
Meadow and Charleston Options
109
○ The trench’s creek interference is affected not only by the maximum allowable
grade, but by the allowable vertical curvature. The vertical curvature affects how
quickly the tracks can change their grade. If Caltrain allows a more-rapid vertical
curvature, the trench will be able to change elevations more rapidly, making it
easier to avoid creek impacts and also reducing the trench length and cost.
○ If Caltrain does not grant a 2% design exception, the trench design might be
impossible. The Hatch Mott McDonald deep trench approach might work, but
there could be potential impacts with the San Antonio Caltrain station.
● Trench interference with Adobe Creek can be reduced by maximizing the slope of the
tracks between Adobe Creek and Charleston Road. That is, move as much vertical
curvature north of Charleston and south of Adobe Creek so that the Charleston/Adobe
stretch is as steep as possible.
○ Slightly elevating the track south of Adobe Creek allows some of the vertical
curvature to occur south of Adobe Creek, allowing the tracks to cross the creek
at an incline.
○ Similarly, moving the vertical curve to the north of Charleston Road also
maximizes the slope between Charleston and Adobe Creek. However, this does
increase the maximum depth of the trench.
5.6.5.2. Questions for Caltrain
● Is it possible for Caltrain to loosen the constraints on maximum grade, maximum vertical
curve, and length between vertical curves allowed for passenger and freight trains?
● Considering that relatively few freight trains operate on the Caltrain corridor, would
reducing the design speed for freight help loosen those constraints further?
● If a trench is constructed for the Charleston and Meadow intersections, would a trench
lid be possible between Charleston/Meadow and how long could the lid sections be
while still allowing adequate spacing for emergency access?
● A crossover track section is currently located north of the San Antonio station. Must this
crossover remain in its current location? If the current location interferes with a grade-
separation design, could the crossover be moved south of the San Antonio station?
5.6.5.3. Adobe Creek Analysis
● Any trench interference with Adobe Creek can potentially be mitigated by widening the
creek below the trench. To the first order, the cross-sectional area of the creek must
match the cross-section of the creek’s culvert under Alma.
○ What are the cross-sectional dimensions of the Adobe Creek culvert currently
under Alma?
● In trench interference with Adobe Creek cannot be avoided, a siphon (either a passive or
powered) could be installed to route the water under the trench.
○ If a passive siphon is used to pass the water under the rail trench, what
maintenance must be performed to keep sediment from reducing the siphon
Meadow and Charleston Options
110
performance? Could a sediment trap be constructed upstream (e.g., near Miller
Ave) to reduce the sediment that reaches the siphon?
○ If a powered siphon is used to pass water under the rail trench, what are the
impacts of a power outage on the siphon? That is, would the unpowered siphons
still allow significant passive flow?
○ During dry periods, would siphons (either passive or powered) allow standing
water which might allow mosquito breeding?
5.6.5.4. Barron Creek Analysis
● If Barron Creek is made to flow over the trench, the trench could be shortened if
Barron Creek can be moved south.
○ Currently, Barron Creek flows north along the west side of the tracks before
crossing under the tracks and Alma. Designers should investigate whether
Barron Creek can be made to cross the trench then flow north on the east side of
the tracks (or on the east side of Alma). That is, make Barron Creek cross the
trench at the same point that it crosses Park Blvd.
5.6.5.5. Groundwater Analysis
● Groundwater can be impacted during construction. Some construction techniques
completely seal the trench during construction, while others require varying amounts of
dewatering pumping during construction. Since large-scale pumping during construction
can dramatically lower the local water table, the trench design should carefully consider
the groundwater impacts during construction.
○ For example, the Carlsbad trench project identified three construction techniques
(Secant Pile Wall, Slurry-Diaphragm Wall, Deep Soil Mixing Wall) which seal the
site in order to minimize the amount of dewatering required during construction.
Would these construction techniques similarly seal a Charleston/Meadow trench?
● While a sealed trench prevents groundwater leakage into the trench, it can still impact
groundwater by interrupting the flow of groundwater. Palo Alto needs to analyze how a
30–40-foot trench affects groundwater flow.
○ For example, after measuring groundwater depths and collecting soil samples,
the Carlsbad trench project performed an analysis to predict the amount of
groundwater mounding on the upgradient side of their trench wall. For a 50-foot
trench model, their analysis predicted groundwater mounding ranging from 0.2 to
4 feet.
○ A similar analysis should be performed for Palo Alto soils to predict the
groundwater impacts for a Charleston/Meadow trench, along with identifying any
possible design techniques (such as permeable fill adjacent to the trench) that
may mitigate groundwater impacts.
○ Considering that developments along El Camino have deep basements, how
much of an incremental effect would a trench have on groundwater flow? Do the
Meadow and Charleston Options
111
El Camino developments push the groundwater flow deeper? Or can
groundwater flow around the buildings?
5.6.5.6. Project Cost and Duration
● While geographic and inflation complicate the comparisons, the AECOM cost estimates
for a Charleston/Meadow trench do not seem consistent with the Reno, San Gabriel, and
Carlsbad trench projects with data that has been publicly available. An independent cost
estimate of AECOM’s work seems warranted given the large disparities and the overall
high cost of the project itself. Any cost comparisons should delineate the reasons for
any cost differences between these projects and a Charleston/Meadow trench.
● Similarly, the AECOM construction duration estimates do not seem consistent with the
actual schedules for Reno and San Gabriel. An independent assessment of
construction duration should include a description of reasons for any schedule difference
between a Charleston/Meadow trench and the Reno and San Gabriel trenches.
5.6.6. Underpass: Specific Study Areas
The Charleston and Meadow Underpass designs were created in response to the criticisms of
the visual impact of the viaduct and hybrid options, the higher costs of a trench or tunnel, the
need to allow for a four-track eventuality, and the prolonged construction impacts of both other
alternatives. Unlike the Churchill Partial Underpass concept, which was submitted by an
engineer and an architect that provided conceptual 3D drawings, the Meadow/Charleston
Underpass concept began with a conceptual sketch. Once COVID hit, the underpass suffered
from limited review and iterative improvements, new restrictions on consulting expenses based
on the new budget limitations, and the limits of Zoom meetings. In addition, the consultants’
design for Meadow differs significantly from the original proposal.
XCAP recommends further iteration of the conceptual designs for Meadow/Charleston. Overall,
concerns raised by the initial concept include:
● The need for property acquisition compared to other alternatives.
● Bike/Pedestrian access, particularly on the west side of the tracks.
● The complexity of routes for bikes, pedestrians, and vehicular traffic.
● Potential traffic diversion into existing neighborhoods.
● Difficulty getting in and out of driveways for homeowners along Charleston on the
East side.
● A lengthy construction period.
5.6.6.1. Underpass Process and Considerations
While the AECOM preliminary design is a useful starting point for understanding the tradeoffs
between ease of turn movements and potential property impacts, a more developed alternative
may differ substantially from what AECOM finally presented to XCAP. While XCAP members
provided cursory feedback on AECOM’s alternative, it was clear further technical iterations were
Meadow and Charleston Options
112
necessary and, for time and budget reasons, substantive comments could not be incorporated
into a revised alternative.
Unfortunately, the COVID emergency also meant that the video prepared for the Virtual Town
Hall which was really a construction phasing video, did not match the renderings and plans, and
thus did not include critical bike connections and did not highlight an additional turn movement
(at Meadow) which had been discussed.
5.6.6.2. Public Outreach
Overall, the XCAP process has made it clear there are no alternatives that stand out as clear
winners that easily achieve consensus community support. All the alternatives have pros and
cons that must be weighed or resolved. The Underpass alternative has the highest possibility of
property acquisition or eminent domain, thus the design refinements and public outreach on this
alternative likely needs to be extensive so the community can understand the trade-offs and
mitigations being considered. This point is especially important if the alternative requires
additional funding from the community.
The Meadow/Charleston Underpass alternatives did not receive the benefit of a live Town Hall
with the ability to explain the concept. The Virtual Town Hall explained the existing AECOM
design, but did not present it as a preliminary concept that needed more iterations to address
the significant issues identified. And the inconsistencies between the drawings and the videos
led to some confusion, further impacting the public’s ability to understand the initial concept.
In the future, it is critical to ensure all work is consistent across all modes of communication,
particularly on bike/pedestrian design.
5.7. Additional Considerations
5.7.1. Traffic Studies
Traffic studies were performed by Hexagon Transportation Consultants. The report can be
found in Appendix B 3 1 Final Traffic Study – Hexagon Traffic Consultants. Traffic analyses
were performed considering Meadow and Charleston together.
5.7.1.1. Meadow and Charleston Viaduct
The results of the traffic study for existing traffic conditions on the Meadow and Charleston
Viaduct are summarized in the table below:
Meadow and Charleston Options
113
Level of Service improves from E or F to Ds if a Viaduct were constructed.
Meadow and Charleston Options
114
Analyses of the traffic in future conditions are summarized in the table below:
The results show that level of service returns to F when modeled under future traffic conditions in 2030, and level of service remains
the same as it does today.
Meadow and Charleston Options
115
5.7.1.2. Meadow and Charleston Hybrid
Traffic impacts would be similar to that of the Viaduct.
5.7.1.3. Meadow and Charleston Partial Underpass – With U-Turn at Alma Village
Circle
Traffic analyses involved three options for the northbound and southbound ramp intersections at
Meadow Drive:
1. Traffic signal at the Alma southbound off-ramp and no control at the Alma northbound
off-ramp. Left-turning traffic from eastbound Meadow would have to find gaps in the
uncontrolled traffic flow on westbound Meadow.
2. Traffic signal at the Alma southbound off-ramp and an all-way stop control at the Alma
northbound on-ramp.
3. Traffic signals at both the southbound off-ramp and northbound on-ramp.
The results are summarized in the table below:
Meadow and Charleston Options
116
When compared to the level of service with existing intersection designs, all three options show improvements in level of service.
The improvements are very similar, with perhaps Option 1 edging out the other two options with slightly more improvement than the
others.
Meadow and Charleston Options
117
5.7.2. Noise
The Noise and Vibration Final Report is available in the Appendix B 4 Noise and Vibration
Comparative Analysis Report. The report explains that of all the types of noise caused by trains
(horns, propulsion/engine noise, wheel/rail noise and other), the most significant source in a
“train pass by event” is the horn. The Federal Railroad Administration requires that train
engineers sound their horn four times when approaching a grade crossing.53 All of the options
would eliminate horn noise, which would very significantly reduce noise compared to the
situation today.
Source: pg. 20 Noise Vibration Comparative Analysis Report
It should be noted in the chart above that the noise report did not consider the possibility of
using a noise parapet (sound wall) to reduce wheel/rail noise, but that if this noise treatment
were applied, there would be a reduction.
Also, in the chart above, Closure is only an alternative for Churchill (not Meadow/Charleston).

quiet#:~:text=Under%20the%20Train%20Horn%20Rule,of%20all%20public%20grade%20crossings.
Meadow and Charleston Options
118
Generally, the noise impact of all of the solutions is likely to be about the same, with the
exception that the hybrid will measurably reduce road noise from Alma Street for some areas.
Commenters to XCAP expressed the desire to learn more about the noise impacts -- in
particular, the noise study provided to XCAP did not provide data on noise effects more than
two homes away from the rail corridor. In addition, the report indicated “Second row homes to
both the east and west receive some acoustical shielding by the first row of homes” but
neighbors questioned this concept since homes along the West side of the track are only one
story and train in some scenarios could be higher than a single-story home. Additional data
may be necessary in order to address community concerns.
For ground vibration, the report found the following:
Source: pg. 24 Noise Vibration Comparative Analysis Report
As can be seen in the figure above, the Viaduct provides the most significant vibration
reduction.
Finally, the report also discussed the relative noise impacts during construction:

5.7.3. Agencies Involved in Groundwater and Creek Issues
According to Joe Terisi, a Registered Civil Engineer54, our local creeks are assigned the
following “listed beneficial uses” by the Regional Board’s San Francisco Bay Basin Plan:
5.7.3.1. Matadero Creek
● Cold Freshwater Habitat (COLD)
● Warm Freshwater Habitat (WARM)
● Fish Migration (MIGR)
● Fish Spawning (SPWN)
● Preservation of Rare and Endangered Species (RARE)
● Wildlife Habitat (WILD)
● Water Contact Recreation (REC-1)
● Noncontact Water Recreation (REC-2)
5.7.3.2. Adobe Creek
● Cold Freshwater Habitat (COLD)
● Warm Freshwater Habitat (WARM)
● Wildlife Habitat (WILD)
● Water Contact Recreation (REC-1)
● Non-Contact Water Recreation (REC-2)
5.7.3.3. Permitting Agencies
Matadero and Adobe Creek are subject to the jurisdiction of several permitting agencies. It is
likely that all of the agencies below would have to be consulted in order to successfully plan any
changes that could affect the creeks:
● Federal Emergency Management Agency
● Valley Water (formerly Santa Clara Valley Water District)
● State Department of Fish & Wildlife Stream Alteration Agreement
● Regional Water Quality Control Board Section 401 Water Quality Cert
● US Army Corps of Engineers Section 404 Permit

2-C Update from Technical Working Group Regarding Review of New Ideas pages 12-16
Rail Safety in Palo Alto
121
6. Rail Safety in Palo Alto
Historically, safety drove grade separation projects in many cities, including the underpass at
Embarcadero Road here in Palo Alto. Operation Lifesaver55, a non-profit funded by both the
federal government and the railroad industry, estimates that 95% of railroad fatalities in the US
are due to either pedestrian trespass or accidents at grade crossings.
This section attempts to record the current state of grade crossing safety in Palo Alto, and
recommend how the City can move forward to ensure that our community will be safer in the
future.
6.1. Incident Data
Between 2008 and August 2020, there were 25 incidents at Palo Alto’s four grade crossings in
which a train struck, or nearly struck, either a pedestrian or a vehicle.56 Eight were fatalities.
In the same period, there were 11 incidents — seven with vehicles and four with pedestrians —
at the Charleston Road crossing alone. All of the pedestrians were killed, and all were ruled a
suicide according to data provided by the Federal Railroad Administration. One of the two
vehicular fatalities was ruled a suicide.
At East Meadow Drive there were six incidents — four with vehicles and two with pedestrians.
Both pedestrians were killed, and both were later ruled suicides according to the FRA database.
In addition, a vehicle went around the gate in 2007 and an occupant was killed, although it was
not ruled a suicide.
At Churchill Avenue there have been seven incidents during the 2008 - 2020 time span, all
involving vehicles, and none fatal. (However, these seven accidents accounted for $63,500 in
vehicle damage according to the FRA.) There has also been one incident at Palo Alto Avenue
in this period, which was not fatal.
The Federal Railroad Administration maintains a system called the Web-Based Accident
Prediction System57 with data about every incident on every rail crossing in the US. A query of
this database on August 6, 2020 produced the following summary data for our crossings in
Palo Alto:

Palo Alto Ave 0.058481 0 96 79 14,200
The “Predicted Collisions” column in this table is described by the FRA as the “probability that a
collision between a train and a highway vehicle will occur at the crossing in a year.”
The value for Charleston Road, in other words, predicts a collision about every two years, and
the aggregated data would suggest at least one grade crossing accident in Palo Alto every year.
This value is currently the 19th-highest prediction score in California, and higher than any other
crossing in Santa Clara County, based on queries to the WBAPS.
This number should be used carefully, however, as the FRA also states: “WBAPS does not
state that specific crossings are the most dangerous. Rather, the WBAPS data provides an
indication that conditions are such that one crossing may possibly be more hazardous than
another based on the specific data that is in the program.” More detailed information is
available on the Web-Based Accident Prediction System website:
https://safetydata.fra.dot.gov/webaps/.
The railroad crossings in Palo Alto have historically created health and safety challenges for
vehicles, pedestrians, and bicyclists. For example, according to the Palo Alto Historical
Association website58, a tragic collision at the crossing near Palo Alto High School in 1927
sparked a movement to improve safety at that intersection. Public advocacy and insistence on
building an underpass (then known as a “subway”) led to the construction of the Embarcadero
underpass nine years later in 1936.
Much later, Palo Alto suffered two youth suicide cluster incidents in 2009-10 and 2014-15,
including the four pedestrian deaths at the Charleston Road grade crossing that were later ruled
suicides. The City of Palo Alto subsequently implemented several measures to support our
youth’s health and well-being, including public education about mental health resources59. A
comprehensive strategy was developed with input from key leaders in adolescent behavioral
health, education, law enforcement, and Caltrain, also evolved to address means restriction
(reducing access) and railroad safety.

In collaboration with Caltrain and the City of Palo Alto’s Emergency Response Department,
several lethal means restriction methods were implemented, including:
● Professional track watch program with monthly incident reports.
● Removal of vegetation to enhance vision along the Caltrain rail corridor.
● Uniform eight-foot-tall fencing with 18-inch anti-climbing winglets on the East side of
Alma Street.
● Intrusion Detection System (IDS) with nine cameras at the East Meadow Drive crossing.
● Warning system to prevent trespassing on the rail corridor.
● Signage for the assistance; crisis/suicide emergency hotline.
6.2. Safety Considerations for all Alternatives
Public safety must be a significant consideration in the implementation of any grade
separation alternative. Regardless of what grade separation alternatives are eventually
chosen, important safety considerations should be applied corridor-wide — not just at the
location of new separations.
The XCAP recommends that the City Council adopt standardized safety protocols for the entire
corridor as part of Caltrain’s Corridor-wide grade separation project.
6.3. The Importance of Means Restriction
According to Harvard School of Public Health’s Means Matter campaign60, restriction to lethal
means is one of the most effective ways to prevent a suicidal person’s access to mechanisms
that cause injuries and fatalities. Although this campaign focuses on firearm-related deaths, the
train is also considered a lethal means for intentional harm.
In 2014, Scott Gabree, PhD, made a presentation titled “Potential Countermeasures to Mitigate
Suicides on the Railroad Right-of-Way.”61 This document shared several prevention efforts,
including the use of blue lights,62 gatekeeper training, public awareness campaigns, signage for
crisis center hotlines, media guidelines, means restrictions such as fencing, and track
surveillance. XCAP recommends the incorporation of this document into discussions with
Caltrain related to corridor wide safety improvements.

61 Potential countermeasures to mitigate suicides on the railroad rights-of-way. From https://www.sprc.org/resources-
programs/potential-countermeasures-mitigate-suicides-railroad-rights-way
62 Some studies suggest that installing blue lighting on train platforms can reduce suicides. For example, this study from 2014:
https://pubmed.ncbi.nlm.nih.gov/25151192/
Rail Safety in Palo Alto
124
According to Frank Frey, general engineer with track safety expertise for the Federal Railroad
Administration,63 the safest option for preventing injuries and fatalities at a dangerous crossing
is closure. He also recommended tall fencing around “hot spot” areas where illegal trespass
has occurred.
6.4. Safe Construction Recommendations
This section includes recommendations based mostly on the research and experience of former
XCAP member Pat Lau, who had previously worked on Project Safety Net.64 These
suggestions are for the Council’s consideration for future design development as they go
beyond the level of design detail available for XCAP at this time.
6.4.1. Fencing
Good fencing is an essential part of means restriction. The City should work to install uniform
eight-foot-tall uniform fencing with an 18-inch anti-climbing winglet along the West side of the
right-of-way to ensure access to the tracks is restricted. In addition, any sound barriers
constructed as part of the grade separations, including for at-grade alternatives, can be
considered an additional safety measure.
When adding fencing, it is also important to consider the “no-person’s land” in between fences,
in case a new fence is installed in parallel to an existing fence — such areas can lead to their
own set of challenges.
6.4.2. Considerations for Trenching and Tunneling
Illegal access to the tracks may be easier in places where the rail line enters a trench or tunnel,
or anywhere near an open trench. Fences and sound barriers at the entrance to any potential
trench or tunnel must be installed at these known “hot spots.” In addition, an Intruder Detection
System (IDS) with multiple cameras and a warning system may be needed to monitor the rail
corridor and identify at-risk behavior for intentional and unintentional injuries and fatalities.
6.4.3. Station Areas
Since grade separations still allow access to the tracks at station areas, additional safety
measures may be necessary for stations to prevent pedestrians from trespassing there. For
example, it will be important to make it clear which agency is responsible for responding to
emergencies at or near stations.
63 Frank Frey, General Engineer, Federal Railroad Administration, interviewed by former XCAP member Pat Lau.
64 Lau’s original safety recommendations submitted at XCAP meeting https://connectingpaloalto.com/wp-content/uploads/

Rail Safety in Palo Alto
125
6.4.4. Considerations for Passing Tracks
Finally, as Caltrain has indicated the potential need for passing tracks in Palo Alto (bringing the
total number of tracks at a given spot from two to three or four), it is important to design and
locate such segments so that they do not make it easier for trespassers to gain access to
the tracks.
6.5. Additional Recommendations
Upon selection of final designs, XCAP recommends that egress and access safety protocols
should be outlined and negotiated with Caltrain to ensure uniform protection across the corridor.
If the City must fund improvements, it should consider the cost of installation and maintenance
of countermeasures to prevent illegal access to the Caltrain rail corridor as part of its budget
process. The injury and fatality prevention efforts may include means restriction equipment
such as standardized eight feet tall fencing with 18-inch winglets, Intruder Detection Systems
(IDS) for track surveillance, flashing lights, warning systems, gatekeeper training, public
awareness campaigns, signage for crisis center hotlines, and media guidelines.
XCAP also recommends that the City/School Liaison Committee, the City/School Traffic
Committee, Safe Routes to School representatives, PABAC, PTAC, and PAUSD be consulted
regarding the safety and efficacy of the recommended redesign alternatives. Mental health
resources should be shared with key stakeholders including schools and community-based
organizations, in an effort to prevent intentional injuries and fatalities on the Caltrain rail corridor.
Recommendations and Lessons Learned
126
7. Recommendations and Lessons Learned
The XCAP has three key sections for future considerations: Policymaker Recommendations,
Technical Recommendations and Lessons Learned.
7.1. Recommendations for Policymakers
The following is a list of general recommendations for policymakers. The goal of these
recommendations is to provide policymakers some alternatives for areas of on-going work.
7.1.1. Review Existing Reports and Policies to Inform Future Study and
Consider Future Additional Criteria
The 2030 Comprehensive Plan (adopted Nov 2017), the City of Palo Alto Bicycle + Pedestrian
Transportation Plan (2012) and the Rail Corridor Report (2013) all provide guiding principles
and foundations which can be reviewed to guide future work.
2030 Comprehensive Plan
Relevant Comprehensive Plan Policies and Goals should be fully incorporated
into the grade separation guidelines and criteria.
The 2030 Comprehensive Plan indicates that the primary sustainable transportation goal
(Goal T-1) is to emphasize walking and bicycling to reduce GHG emissions and the use
of single-occupancy motor vehicles. Future grade separation design iterations
should incorporate this goal as part of the primary focus.
The Comp Plan also calls for prioritizing investments for “enhanced pedestrian access
and bicycle use within Palo Alto” by incorporating improvements from related City plans
like the 2012 Palo Alto Bicycle + Pedestrian Transportation Plan (Policy T-1.19). It also
calls to “increase the number of east-west pedestrian and bicycle crossings
across Alma Street and the Caltrain corridor, particularly south of Oregon
Expressway” (Program T1.19.3). It also seeks to “enhance connections to, from and
between parks, community centers, recreation facilities, libraries and schools for all
users” (Policy T-3.2). In addition, to “avoid major increases in single-occupant vehicle
capacity when constructing or modifying roadways unless needed to remedy severe
congestion or critical neighborhood traffic” - but also that “when capacity is increased,
designs must balance the needs of motor vehicles with those of pedestrians and
bicyclists.” (Policy T-3.3)
The Comprehensive Plan also calls for a study to evaluate the implications of
grade separation on bicycle and pedestrian circulation (Program T3.15.2 ). And that
“until grade separation is completed, improve existing at-grade rail crossings to ensure
the highest feasible level of safety along the corridor and provide additional safe,
Recommendations and Lessons Learned
127
convenient crossings (Policy T-3.17). The plan also calls for improving safety and
minimizing adverse noise, vibrations and visual impacts of operations in the Caltrain rail
corridor on adjoining districts, public facilities, schools and neighborhoods with or without
the addition of High-Speed Rail Policy (T-3.18)
Additional Comp Plan visions, goals and policies that might be relevant for future
planning are available in the Appendix B-12 Palo Alto Comprehensive Plan Excerpts.
City of Palo Alto Bicycle + Pedestrian Transportation Plan (2012)
The 2012 Bike Plan discusses several projects that form part of the bike/pedestrian
network across the Caltrain ROW, including suggested new bike/pedestrian only
crossings that have been recommended for study. (see New Bike/Pedestrian
Connection beyond Meadow/Charleston for Interim Mitigations section below for more
details).
Palo Alto Rail Corridor Study 2013
The 2013 Rail Corridor Study65 identified opportunities to create more East/West
connectivity across the Caltrain corridor for cars, bikes and pedestrians. XCAP
recommends the Council and Staff consider the principles of that report when refining
design concepts for ALL the grade separation alternatives.
The report explored opportunities to improve the circulation framework and connections
while specifically highlighted the following:
● Provide additional rail crossings in the southern section of the study area.
● Strengthen the pedestrian and bicycle circulation framework and make
connections to citywide facilities and amenities.
● Create a walkable, pedestrian and bicycle-friendly community with convenient
and safe access to goods and services.
● Implement a Layered Street Framework.
The existing policies along with the now more developed possible grade separations
alternatives could be used to update the City Council criteria and provide a framework for future
work. More information is also available in Appendix B 13 - Rail Corridor Study – 2012 Excerpts.
7.1.2. Formalizing Bike/Pedestrian Input
Given the importance placed on bikes and pedestrians in the Comprehensive Plan, it is critical
that more formalized, targeted feedback is sought for any additional work on grade separations.
XCAP’s understanding was that Staff would be liaising with the appropriate groups to garner
feedback regarding bike/pedestrian design but that did not occur. Therefore, as part of future
65 https://www.cityofpaloalto.org/civicax/filebank/documents/38025
Recommendations and Lessons Learned
128
work, XCAP recommends the Council and City Staff develop a formal series of feedback
from groups including:
● Palo Alto Unified School District (PAUSD)
● Palo Alto Bicycle Advisory Committee
● Safe Routes to School (SRTS)
● Palo Alto Council of Parent Teacher Associations (PTAC)
● School Facilities personnel
● City/School Traffic Safety Committee
7.1.3. Geotechnical and Groundwater Analysis
The hybrid, trench and underpass alternatives (both Churchill Partial Underpass and
Meadow/Charleston Underpass) all require significant excavation. The XCAP recommends that
the council authorize a preliminary geotechnical and ground water analysis. This information is
needed to help refine the cost estimates and provide insight about alternative construction
methods (such as Jacked Box). (See Construction Methodology section.)
7.1.4. Passing Tracks and their impact on Design
Caltrain has made it clear that when presenting designs for consideration, Palo Alto must be
able to show whether the design “precludes” the ability to add two additional passing tracks to
accommodate High Speed Rail in the future. If HSR decides it needs four tracks, Caltrain and
the City of Palo Alto have indicated HSR should bear the additional cost.
7.1.5. Caltrain Advocacy
The City should prioritize working on the Caltrain Corridor Wide Study and be active participants
in scoping future areas of study - concentrating on the issue of potential passing tracks in
Palo Alto, design standards that might impact Palo Alto’s design alternatives and construction
methodologies that could cut costs.
7.1.6. New Bike/Pedestrian Connections as Key Infrastructure and
Interim Mitigations
The 2012 Palo Alto Bicycle Plan, the 2013 Rail Corridor Study and the 2030 Comprehensive
Plan (2017) all highlight two key additional crossings that should be studied: Seale Avenue/
Peers Park in North Palo Alto and the vicinity of Loma Verde/Alma and Matadero Creek in
South Palo Alto. Each of these projects provides stand-alone improvements that will help
develop Palo Alto’s bike and pedestrian network but, in addition, these projects could be
constructed ahead of any grade separation projects to provide a safe crossing for
bikes/pedestrians during the long construction periods expected for grade separations
(2-6 years). In addition, these projects could be completed regardless of whether or not passing
tracks are needed.
Recommendations and Lessons Learned
129
The Loma Verde/Matadero Creek crossing would close a 1.3 mile bike/pedestrian crossing gap
between the existing California Avenue bike/pedestrian tunnel and the surface crossing on
Meadow Drive. It would provide a path connecting to Hoover Park to the east and beyond. In
addition, it would also bridge a missing link between the South of Midtown neighborhood and
the California/Ventura Mixed Use District and the Ventura neighborhood, then further
connecting to the Bol Park Bike path that leads to Gunn High School and the Stanford Research
Park employment center. And it would also provide a link between the El Carmelo School and
Hoover Park for residents of the Ventura neighborhood.
7.1.7. Safety
Regardless of which grade separation is chosen, important safety considerations should be
applied corridor-wide, not just at the location of new separations. The City Council should
consider adopting standardized safety protocols for means restrictions the entire corridor as part
of Caltrain’s corridor-wide grade separation project.
Policymakers should also consider the cost of installation and maintenance of counter
measures to prevent illegal access to the Caltrain corridor as part of the budget process for
alternatives.
More information about Safety considerations is in Chapter 6.
7.2. General Technical Recommendations
The following are recommendations are technical in nature and relate to all the alternatives:
7.2.1. Noise and Vibration Study Addendum
XCAP received a number of concerns related to the Noise and Vibration Study. This report is
one of the most technical received by XCAP and, while it was likely completed in accordance
with industry standards, would benefit from additional work to explain impacts (or lack thereof) in
relation to specific areas of concerns raised by the public. For example, the diagrams included
impacts to homes in the first and second rows adjacent to the tracks but did not explain what
happens beyond that distance. That should be addressed, particularly because there was
concern that a “typical” noise study considers dwellings that might be two stories, but that the
area in South Palo Alto is primarily a single-story overlay (mostly low slung Eichler homes) and
that sound might carry farther. Any additional information to further contextualize the data for
Palo Alto would be helpful to inform the public.
7.2.2. Urban Designer
XCAP recommends the City consider hiring an Urban Designer who can use all of the
information gathered to date and see if there are ways to make the engineering requirements
into comfortable environments for all modes of movement.
Recommendations and Lessons Learned
130
7.2.3. Safe Construction Recommendations
Uniform 8-foot-tall fencing with an 18-inch anti-climbing winglet should be considered for the
entire west side of the ROW given that current fencing is inconsistent.
If a trench or tunnel is considered, designs should include special fencing or other barriers to
address critical “hot spots” and deter any potential intrusion.
Intruder Detection Systems (IDS) with multiple cameras and a warning system should also
be considered.
More information about Safety is also available in Chapter 6 Rail Safety in Palo Alto.
7.3. Technical Recommendations by Alternative
The following recommendations are specific to each alternative:
7.3.1. Churchill Closure with Mitigations
1. The following suggestions were made:
a. Mitigations should include the 2016 Bike Project and evaluate impacts to El Camino
and Embarcadero and Embarcadero/Emerson/High Street and along both sides of
Embarcadero (see: https://www.cityofpaloalto.org/civicax/filebank/documents/53341)
(approved but removed from the Capital Improvement Program due to COVID - has
been pushed out past the 5-year timeline).
b. Unofficial student pick-up/drop off locations along Embarcadero slip road and
possible safety mitigations needed if more cars travel on that road.
c. Embarcadero intersection should be revisited when alternatives for Palo Alto Avenue
and Downtown are selected.
d. Lincoln/Kingsley/High/Embarcadero multi-way intersection issue needs to be
addressed to reduce neighborhood through traffic.
e. Consider working with Town & Country on reducing congestion on Embarcadero/
El Camino.
f. Review proposed Pedestrian overpass over Embarcadero for safety issues.
g. Consider creating a comprehensive bike/pedestrian connection plan.
h. Bike/Pedestrian path at Seale before building the Churchill bike/pedestrian to allow
safe crossing during construction. (and how that might be used for phasing a
closure) (Note: bike/pedestrian path is consistent with park use and can be done on
dedicated park land).
i. Study whether Park Blvd should be reopened between Southgate and Evergreen
Park. Consider testing an opening. Neighborhood outreach is critical.
Recommendations and Lessons Learned
131
j. Consider mitigations (ex. stairs) for the northwest corner of the Embarcadero grade
separation, where westbound foot traffic (represented by the red arrow) on the north
side of Embarcadero Road travels under the grade separation and then up through
landscaping on the northwest embankment towards Town & Country, with many
continuing to Palo Alto High School by looping across Embarcadero using the
Embarcadero bike/pedestrian bridge adjacent to the railroad tracks (represented by
the yellow arrow).
k. Consider a traffic signal at North California/Alma to have fewer cars along Churchill
and to provide a signalized left out of Old Palo Alto.
2. Additional bike/pedestrian crossing mitigation future study areas:
a. Add Bike/Pedestrian Crossing at Seale
i. Recommended in Rail Corridor Plan
ii. Adds a Bike/Pedestrian crossing that can be built while mitigations are being
built.
iii. Would provide a more direct Safe Route to School for Greene and Walter
Hays from West of Alma and for Palo Alto High School from students West of
Alma and South of Churchill.
iv. Reduces bike traffic on congested California Avenue bike/pedestrian tunnel
and on Churchill tunnel.
v. Bikes on the west side of tracks end up on Park Blvd which is a bike path.
vi. Alternatives for Seale design could be center of the road or property
acquisition to create bike/pedestrian ramps to separate from Alma and tracks.
b. Bike Option 2
i. Explore closing Churchill to cars on the East side between Alma and Emerson
- only homeowners and their guests would use the road. Residents would
enter/exit Churchill from Emerson Street. Explore need and possibility for a
turn-around at the end of resulting cul-de-sac.
ii. Consider the effect of changes on moving trucks, garbage trucks, emergency
vehicles, etc. on an altered Churchill Ave block. Consider any traffic
implications including any additional traffic onto Embarcadero.
iii. Explore use of the area from curb and landscaping between curb and sidewalk
on both sides of Churchill Ave to enable an increase in width of ramp.
iv. Explore flatter, wider, taller and fully lit crossing with increased sightlines.
Consider moving the entry to ramp further back from Alma to decrease ramp
grade.
3. Analyze the impacts of widening the Alma Street bridge on the overall traffic network and
any necessary mitigations.
Recommendations and Lessons Learned
132
4. Consider a cost-benefit analysis of whether the Embarcadero grade separation might
eventually need replacement, whether opportunities exist to improve all turn movements
if replaced, and what impact that has on other east/west arterials and their planned
improvements since closure of Churchill could impact network resiliency.
5. Consider impacts of any roadway modifications to east/west travel, particularly regarding
decisions made on the future Downtown coordinated Area Plan and the Palo Alto
Avenue crossing.
6. Given the impacts to the overall project timelines from COVID, it is expected that an
updated Traffic study eventually will be needed. The following suggestions are areas of
future study that could be included:
● Expand Traffic Study to include impacts beyond 2030 - Analysis describing network
impacts of the proposed mitigations beyond 2030 are needed. Given the uncertainty
of long-range forecasts, analysis with certain confidence bands and future scenario
analysis should test how sensitive the LOS forecast predictions are to changes in the
input assumptions.
● Perform network LOS analysis of proposed mitigations and improvements to
understand the queuing effects of these mitigations and whether they create capacity
constraints at other intersections.
● Consider potential delays to public transit or/and school buses that may result from
concentrating more traffic on fewer roadways.
7.3.2. Churchill Partial Underpass
If the Council would like to pursue the Partial Underpass, further design review should seek to
reduce the underpass cost, size and encroachment within the Caltrain ROW. Some ideas
include:
● Explore whether raising the rail tracks by a few feet, which would reduce both the
underpass depth and length along both Churchill and Embarcadero, potentially reducing
property impacts and cost and improving visual appearances.
● Explore ideas to reduce the width of Churchill’s lanes/shoulders to reduce the underpass
width, further reducing excavation and construction costs.
● Explore whether it is possible to design a bike/pedestrian crossing closer to Churchill
itself to address circuitousness created by having the bike/pedestrian crossing at either
Kellogg or Seale.
● Work with Caltrain to address encroachment on their ROW.
● Model whether the building of a Partial Underpass could cause auto traffic inducement.
Recommendations and Lessons Learned
133
7.3.3. Churchill Viaduct
If the Council would like to pursue the Viaduct, some ideas for areas of further study include:
● Consider the exploration into a viaduct over Embarcadero, but with a reduced and
diminishing height at the Churchill intersection to allow for a Homer-like bike/pedestrian
underpass.
● Model whether building a Viaduct at Churchill would induce auto traffic.
7.3.4. Meadow/Charleston Viaduct
● Provide more detailed plans regarding dimensions, shape and structure to ascertain
visual impacts in order to help communicate to the community what is being proposed.
● Provide more renderings to show the visual impact of the proposed viaduct.
● Provide a plan showing where the viaduct would be placed to one foot of accuracy to
help understand light planes.
● Provide cross sections every 100'-200' from east of Alma Street to the first property on
Park Avenue, shown with potential screening and sound mitigations.
● Provide a formal accounting of how many properties are affected by the viaduct showing
a longitudinal profile of the track elevation compared to the lots affected.
● Additional noise analysis, including a prediction for noise levels farther from the tracks.
A large number of commenters are concerned that the viaduct, because of its height, will
transmit sound farther than the other alternatives and they would like to understand what
this will actually mean.
● Partner with a landscape architect and/or urban designer to ensure that the planned
structure and any improvements to the land under the structure are compatible with the
look and feel of the rest of the city.
Usable Space
Policymakers should consider the possibility that negotiating with Caltrain could provide the City
with a new opportunity – space at ground level that would previously have been occupied by
train tracks would now be vacant.
The XCAP recommends further study of potential uses of this space be considered as part of
Caltrain’s Corridor-wide grade separation study. Caltrain may have multiple places where cities
would be asking for similar use permits, and they could consider acceptable public uses as part
of their study.
Maintenance
If the viaduct concept is pursued further, XCAP recommends that Staff work with Caltrain to
negotiate the long-term maintenance of this land after construction and in perpetuity to maintain
Recommendations and Lessons Learned
134
attractive landscaping. Standards related to this issue, including whether fencing will be needed
should be clarified and included in formal agreements as discussed in the section on Safety.
Visual Design and Privacy
To improve the visual appeal of a viaduct, consider a variety of construction materials, shapes,
and surface treatments that could enhance how a viaduct fits into the landscape. Any viaduct
should be designed in close collaboration with the community, working with landscape and
urban designers, to build community support. The use of noise barriers as a potential way to
increase privacy for the homes along the tracks should be explored.
7.3.5. Meadow/Charleston Hybrid
● Explore whether the maximum track height can be lowered to less than 15 feet with
minimal impact to properties.
● Consider if there might be some partial acquisitions that could enable giving us some
advantage in height and identify which properties could require driveway modifications.
● Consider sound mitigations and explain what they would look like.
● Provide more detail on what the bike and pedestrian pathways would look like.
● Explore whether the maximum grade on the bike and pedestrian ramps can be lowered
to 5% or less and what is the impact on total ramp length (and possibly properties).
● Explore mitigations for eastbound bikes traveling downhill that may have limited sight
and limited stopping distance approaching the Alma intersection.
● Study whether new grade separation designs may increase capacity and induce more
traffic and what additional protections will be necessary to mitigate more bikes sharing
the road. (Ex: Will we need protected bike lanes and how far would they need to
extend?)
● Identify how new grade separation designs will impact Charleston/Arastradero’s design
needs beyond 2030.
● Confirm whether this design precludes the ability to add two additional tracks for HSR if
required?
● Ensure there is enough queuing space for cyclists traveling eastbound towards each
intersection to accommodate those waiting for a traffic signal.
7.3.6. Meadow/Charleston Trench
● Explore whether the trench depth could be reduced by designing bridges with thin decks
and providing minimal clearances under the bridges to reduce construction costs and
potentially reducing trench/creek interference.
● Furthermore, identify designs (such as trusses) that minimize road bridge-deck
thickness. Also quantify the required height of such designs. In particular, explore
Recommendations and Lessons Learned
135
whether a bow-string arch or tied-arch designs could produce an attractive design that
the community might embrace.
● The current AECOM trench design does not completely seal the trench, requiring pumps
to continually remove the slow trickle of groundwater that enters the trench. Explore
whether sealing the trench to avoid groundwater leakage is possible and more desirable.
● Analysis should be done to predict groundwater impacts for any trench design
considered, and design alternatives that provide different mitigations for groundwater
impacts should be identified.
● Explore other methods of trench wall supports (such as overhead struts) not considered
by AECOM to explore alternatives that could reduce vegetation restrictions from the
proposed tiebacks.
● Work with Caltrain to identify any designs that could improve the vertical curve
constraints that impact design flexibility for the trench.
● Explore with Caltrain whether trench lids would be possible between Charleston/
Meadow and how long could the lid sections be while still allowing adequate spacing for
emergency access.
● Explore with Caltrain (and potentially Mt. View) whether the crossover track section
located north of the San Antonio station can be relocated (perhaps south of San Antonio
Station) to provide greater design flexibility.
● Identify the cross-sectional dimensions of the Adobe Creek culvert currently under Alma.
● Explore if a rail trench reduces the vertical clearance of Adobe Creek, whether the
vertical interference could be mitigated by widening and/or deepening the creek as it
passes under the rail trench. If it is possible, identify how wide the creek can be made
and the corresponding vertical clearance that is required to maintain sufficient creek
throughput under the trench.
● Identify what maintenance must be performed to keep sediment from reducing the
siphon performance if a passive siphon is used to pass the water under the rail trench.
Consider whether a sediment trap be constructed upstream (e.g., near Miller Ave) to
reduce the sediment that reaches the siphon.
● Consider if a powered siphon is used to pass water under the rail trench, what would be
the impacts of a power outage on the siphon and whether the unpowered siphons still
allow sufficient passive flow to avoid flooding.
● Explore whether during dry periods, would siphons (either passive or powered) allow
standing water to accumulate and lead to mosquito breeding.
● Barron Creek is relatively shallow, so it may be preferable to have it pass over the trench
instead of under the trench. Since Barron Creek currently takes two 90 degree turns on
the west side of Alma, consider whether Barron Creek instead can take its two
90 degree turns on the east of Alma (or under Alma). Put differently, explore if Barron
Creek could be straightened so it crosses the trench at the same point that it crosses
Park Blvd.
Recommendations and Lessons Learned
136
● Perform ground water analysis to determine whether construction techniques (such as
Secant Pile Wall, Slurry-Diaphragm Wall, Deep Soil Mixing Wall, and Cantilever Wall
with Sheetpile Shoring) will meet criteria for Groundwater Control. Identify if these
construction techniques could similarly seal a Charleston/Meadow trench.
● Evaluate the groundwater in the area surrounding a Charleston/Meadow rail trench and
identify at what depths does groundwater flow occur.
● Identify how a rail trench with a depth of 30-40 feet could interfere with the groundwater
flow. Identify if the groundwater might rise to approximately the same height on both
sides of the trench and whether design techniques (such as permeable fill adjacent to
the trench) can mitigate groundwater impacts of a trench.
● Identify how current/future developments along El Camino that have deep basements or
foundations, might have similar impacts on groundwater flow as the trench or whether
the space between buildings would reduce groundwater impacts.
● Consider obtaining an independent cost estimate and project comparison delineating the
differences between the Charleston/Meadow trench and the Reno, San Gabriel, and
Carlsbad trench projects (with publicly available data if possible, to minimize cost).
● Consider obtaining an independent construction duration estimate and project
comparison delineating the differences between the Charleston/Meadow trench and the
Reno, San Gabriel, and Carlsbad trench projects (with publicly available data if possible,
to minimize cost).
7.3.7. Meadow/Charleston Underpass
7.3.7.1. Bike Design
In the Meadow/Charleston designs, bikes and peds are grade separated from the train and cars
along Alma - which is seen as a potentially significant safety upgrade by providing dedicated
bikeways. As stated in the Comprehensive Plan, safer and more direct bike/pedestrian routes
also help achieve the goal of reducing reliance on single occupancy vehicles, including traffic
levels in the corridor. Additional design review should focus on the necessary elements to make
safety and access to a bike/pedestrian separated corridor.
Issues to address in design:
1. Ensure that the bike and pedestrian crossing over Meadow near Park Blvd would be
designed in such a way to provide convenient and safe access for bikers along Park
Blvd attempting to gain access to the bikeway, as well as for bicyclists exiting the
bikeway and turning onto Park Blvd or continuing in a westward direction along Meadow
but now on the right-hand side of the street.
2. Ensure bike paths are designed to have turning radii that are appropriate for cargo bikes
or bikes pulling trailers.
3. Need to optimize design for flatter slopes to make it for safer bike/pedestrian
connections, especially for young children.
Recommendations and Lessons Learned
137
4. A thinner bridge deck reduces the depth of the bike/pedestrian underpass, reducing the
required slope of the bike/pedestrian path. Work with Caltrain to select a thinner rail
bridge.
5. Reducing the needed vertical clearance (height) of the bike/pedestrian path under the
tracks would reduce its required slope.
The volume of bikers (LOS) and their overall speed may have impacts for widths needed
on the path. A good reference is the Evaluation of Safety, Design, and Operation of
Shared-Use Paths-Final Report created by FHWA (available at:
http://www.pedbikeinfo.org/cms/downloads/Eval_SharedUsePaths_Final.pdf)
7.3.7.2. Reduction of Eminent Domain
Design refinement should seek to reduce or eliminate (if possible) the need for eminent domain.
XCAP received significant community feedback about this issue, especially from those
potentially impacted by early conceptual designs. (See correspondence received in the
appendix.)
Design modification to consider:
1. To reduce property impacts, consider reducing the road speeds thereby increasing
permissible road grade and shortening the underpass length. (Example: Jefferson Ave
in Redwood City has a 20-mph speed limit to allow a steep grade to go from El Camino,
under the tracks to Broadway in a short distance. Palo Alto designs were conceived
using “traditional” design speeds, but are those flexible?
2. Can the Charleston roundabout diameter be decreased in order to reduce the amount of
property acquisition?
7.3.7.3. Noise and Vibration
While the train remains where it is today in the Underpass design, an at-grade noise parapet
could reduce noise from passing trains and should be considered as part of the future design.
7.3.7.4. Construction Methods
A technology referred to as Box Jacking (where a precast box is pushed into place) was
identified early on as a potential construction method that could be used to avoid needing
electrified shoofly tracks which are expensive, disruptive and add significantly to construction
time. This method was most recently used in Florida66 and Long Island, NY, resulting in
significantly shorter construction time.
A design goal of the XCAP Underpass Concept was to avoid moving the tracks at all (to reduce
cost, construction time and complexity), but without further geotechnical studies, it is not
possible to determine whether this is feasible. Caltrain has indicated interest in understanding
66 https://www.orlandosentinel.com/news/transportation/os-ne-brightline-tunnel-construction-20200917-cj66ylrgafah7dlb6iiuekatye-story.html
Recommendations and Lessons Learned
138
more about construction methods that could avoid the need to construct electrified shoofly
tracks through its Corridor Wide study, but the City should continue to advocate for this.
XCAP recommends that Staff provide Caltrain the materials gathered through XCAP and
through public comment related to Box Jacking construction for incorporation into Caltrain’s
Corridor-Wide Grade Separation Study.
7.3.7.5. Bridge-Deck Thickness
Reducing the thickness of the bridge deck reduces the depth of the underpass; this reduced
elevation change reduces the underpass length, lowering costs and mitigating neighborhood
impacts. Identify designs (such as trusses) that minimize road bridge-deck thickness. Also
quantify the required height of such designs. In particular, explore whether bow-string arch or
tied-arch designs with a short height could produce an attractive design that the community
might embrace.
7.3.7.6. Passing Tracks and their impact on Design
Caltrain has made it clear that when presenting designs for consideration, Palo Alto must be
able to show whether the design “precludes” the ability to add two additional passing tracks to
accommodate High Speed Rail in the future. Of all the alternatives, the Underpass design does
not appear to preclude that possibility, but this should be confirmed.
7.3.7.7. Public Outreach
Overall, the XCAP process has made it clear there are no alternatives that stand out as clear
winners that easily achieve consensus community support. All the alternatives have pros and
cons that must be weighed or resolved. The Underpass alternative has the highest possibility of
property acquisition or eminent domain, thus the design refinements and public outreach on this
alternative likely needs to be extensive so the community can understand the trade-offs and
mitigations being considered. This point is especially important if the alternative requires
additional funding from the community.
The Meadow/Charleston Underpass alternatives did not receive the benefit of a live Town Hall
with the ability to explain the concept. The Virtual Town Hall explained the existing AECOM
design, but did not present it as a preliminary concept that needed more iterations to address
the significant issues identified. And the inconsistencies between the drawings and the videos
led to some confusion, further impacting the public’s ability to understand the initial concept. In
the future, it is critical to ensure all work is consistent across all modes of communication,
particularly on bike/pedestrian design.
Recommendations and Lessons Learned
139
7.4. Lessons Learned
The following are lessons learned that XCAP thinks are useful for anyone considering grade
separations in the future.
1. Very few vehicles actually go straight across the Caltrain tracks at Churchill (East/West),
and instead Churchill is mainly used for cars wishing to turn North/South onto Alma.
2. When cyclists are forced to use a call button to cross an intersection, that causes a large
group of bikes to gather at peak times. This large group then impacts design concepts
for creating bike/pedestrian crossings because the design must focus on
accommodating these large bunches, rather than a more typical flow of cyclists. When
bikes and pedestrians can be put on a dedicated path that does not interface with
vehicles, this problem is mitigated.
3. Similarly, grade separating bikes/pedestrians from Alma and train creates safer
environment and greater intersection efficiency.
4. The maximum desirable grade for bikes/pedestrians is 5%, preferably 4%.
5. Intersections that allow all 12 movements generally decrease the amount of cut-through
traffic in neighborhoods.
6. Eliminating at-grade crossings eliminates train horns - giving biggest overall noise
reduction.
7. Trip time in town is driven more by traffic signal interruption than traffic speed. (If trying
to improve safety, slowing traffic isn't a showstopper, but adding lights is).
8. Since smoothly flowing traffic has about two-second spacing between vehicles, reducing
the speed limit has little effect on traffic capacity. As a result, traffic flow is improved by
encouraging steady speeds, not necessarily fast speeds.
9. The closure of Churchill moves cars to more intersections than expected.
10. Consultants should put extra emphasis on bike/pedestrian traffic and be familiar with the
large number of bikes at peak times (that don’t necessarily match up with peak car traffic
times) and needs of the Safe Routes to School program.
11. Future traffic studies need to evaluate Bike and Pedestrian Level of Service in
subsequent phases.
