SUBJECT: Pandemic Travel Patterns and Postpandemic Opportunities
RECOMMENDATION
Review and provide input on information on pandemic travel patterns and
postpandemic opportunities.
BACKGROUND
Since March 2020, the COVID-19 pandemic has produced massive changes in the ways
that people work, their patterns of travel, and methods for accessing services and
opportunities. The unprecedented nature of these changes provides fertile ground for a
range of ideas about how life will be different in the postpandemic era. One question of
interest is the degree to which remote work will continue, the difference that this might
make on future commute patterns, and what strategies could be explored to realize
ongoing improvements in traffic congestion and greenhouse gas (GHG) emissions.
The purpose of this report is to present information regarding observed travel patterns
and changed work configuration in the last 20 months and identify potential
opportunities to leverage any benefits associated with pandemic conditions to achieve
.
To that end, staff has analyzed the journey to work, due to the oversized influence of
commute travel on traffic congestion, GHG emissions and transportation infrastructure
considerations.
Pandemic Travel Patterns and Postpandemic Opportunities
December 1, 2021
Page 2 of 22
However, it should be noted that there are also considerable changes in other trip types
associated with the pandemic. These changes include a reduction in local shopping trips;
an increase in delivery trips; increased use of automated vehicles or personal delivery
devices; reduced carpool, vanpool, taxi and ride-hail (e.g., Uber, Lyft) trips; and changes
in school-based trips.
ANALYSIS
Vehicular Traffic Lightened During the Pandemic and Has Now Rebounded to 90%
In early 2020, concerns about the spread of COVID-19 were accompanied by a shift to
remote work arrangements for many Silicon Valley technology companies as well as
changes in consumer behavior (such as reduced eating out, reduced transit ridership, and
increased grocery shopping trips). These shifts were reflected in a slight downward trend
in vehicular traffic and public transit ridership in early 2020.
This trend became a more dramatic drop in March 2020, when the County of Santa Clara
issued a Shelter-in-Place order to prevent severe public health outcomes. At that time,
office-based employers shifted to work-from-home arrangements, schools shifted to
asynchronous or online learning, and many service businesses paused operations. The
resulting decrease in travel demand is reflected in bridge crossing vehicle volume data,
which the Metropolitan Transportation Commission (MTC) uses as a proxy for Bay Area
travel demand.

After a drop of approximately 50% in March 2020, economic activity somewhat returned
in summer 2020 accompanied by an increase in vehicular traffic on Bay Area bridges to
approximately 75% of January 2020 levels. By August 2021, bridge traffic reached 95% of
January 2020 levels as displayed in Figure 1.

Local traffic data provided by the Caltrans Performance Measurement System (PeMS) for
the U.S. 101 freeway in Santa Clara County suggests that traffic volumes in the vicinity
of Mountain View dropped to approximately 60% of typical levels (accounting for
month-to-month seasonality). Since the initial drop, traffic volumes rebounded to about
80% by summer 2020 and are now at 96% (northbound) to 90% (southbound) of typical
levels (see Figures 2 and 3).

Transit Ridership Dropped Dramatically and Has Slowly Rebounded to 20% to 50%
Pandemic-related travel demand reductions were substantially more dramatic for
public transit than for vehicular transportation. For example, while vehicular traffic on
U.S. 101 in Santa Clara dropped by 40% and is now back at 90% of pre-COVID levels,
transit ridership (using BART ridership as a proxy) dropped by about 95% and is still at
only about 20% of pre-COVID levels (see Figure 4).
Similar patterns of a deeper drop and much more gradual recovery have been observed
for services operating in Santa Clara County, including VTA, Caltrain, and Mountain
View Community Shuttle. Caltrain ridership dropped by 98% between February and
April 2020 and has gradually rebounded to approximately 20% of pre-COVID rates (i.e.,
80% below prepandemic levels). VTA ridership dropped by 75% between February and
April 2020, and rebounded to approximately 50% of pre-COVID rates by October 2021.
Mountain View Community Shuttle ridership dropped by 85% and has now rebounded
to approximately 50% of pre-COVID rates.

Given this substantial lag in recovery of transit ridership compared with vehicle traffic,
staff anticipates that it could take years for transit ridership levels to return to
prepandemic levels, while vehicle traffic levels are already at 90% to 95% of
prepandemic levels. Caltrain and other agencies have implemented promotions to
nudge former riders back to transit.

Figure 4: Public Transit Ridership Relative to January 2020
Transit Hesitancy Is Reducing Vehicle Occupancy and Elevating Roadway Traffic
Hesitancy to get back on transit is related to concerns regarding the spread of COVID-19,
including variants and breakthrough cases after vaccination. This hesitancy affects
transit ridership as well as other high-occupancy modes involving people outside a single
household. These modes include corporate shuttles, vanpools, carpools, and shared ride-
hail services. Regular carpooling and vanpooling is also more difficult when employees
have different schedules throughout the week, with some days of remote work and some
in-office work.

Pandemic Travel Patterns and Postpandemic Opportunities
December 1, 2021
Page 7 of 22
Ongoing transit hesitancy has worrisome implications for traffic congestion in the Bay
Area because typical transit occupancy levels are so much higher than that of motor
vehicles. For example, while a typical vehicle carries 1.2 passengers (including the
driver), a bus carries 60 passengers, and a train carries around 500 passengers. Ridership
on Caltrain services prior to the pandemic represented an equivalent of four freeway
lanes of capacity during peak hours, which means that if former riders are hesitant to get
back to transit, some of those currently driving are new vehicle trips diverted away from
2
transit and not the return of former freeway travelers.
Active Transportation Increased, and These New Habits Are Likely to Persist Somewhat
While transit ridership dramatically decreased during the pandemic, participation in
active transportation modes such as walking and cycling increased as community
members sought local outdoor places to exercise, recreate, and social distance during
shelter-in-place orders. In general, rates of walking and biking increased in residential
and lower-density areas such as much of Mountain View, and decreased in higher
density and more employment-oriented areas such as urban Central Business Districts
and office parks.
Recent research on the expected persistence of these changes suggest that 29% of U.S.
residents expect to walk more frequently than they did in the prepandemic era, and 15%
3
of residents expect to bike more frequently than in the prepandemic era. The results,
from a sample of more than 7,000 walkers and bikers, are shown in Figure 5.
Among those interviewed, almost 45% of those who were not regular walkers before the
pandemic indicated an intention to continue walking at a greater frequency during the
postpandemic era. Additionally, 10% of those who were not regular cyclists expect to
ride at a greater frequency postpandemic. Many of those who expect to ride at a greater
experience and exposure to bike riding during the pandemic.

Figure 5: Expected Level of Participation in Active Transportation Postpandemic
This shift toward active transportation represents an opportunity for cities like
Mountain View to capitalize on new habits developed during the pandemic in order to
encourage more active transportation in the postpandemic era. Efforts to encourage
walking and biking are most suitable for first- and last-mile trips to or from transit as well
as short trips within a walkable or bikeable range of up to about three miles.
For example, the Castro StrEATS program, which was initiated to support the recovery
of downtown businesses, has also helped community members to envision and
experience a more walkable downtown environment and has encouraged short walking
downtown business district and Transit Center area. Likewise,
planned execution of as students return to
school campuses is expected to boost walking and biking access to school through
encouragement events and education efforts focused on building confidence, skills, and
traffic safety knowledge among students.

Some Employment Sectors Have Returned to Work
In the 20 months since March 2020, the pandemic has eased, and vaccines have been
of 2,249 per day on January 5, 2021, are now around 160 per day, and 1.47 million (74%
of all residents) have been fully vaccinated. In this context, most service jobs have
returned to in-person work, and many office-based employers have started the process
of returning employees to the office.
For peak hour trips, which are the focus of congestion analyses, trip types that have
rebounded include commute trips by essential workers and people working in health
care, construction, education, and various service sectors. Additionally, school-related
traffic has rebounded, along with commute trips for a small portion of professional
workers doing office-based work.
almost 50% of jobs
in Santa Clara County are not eligible to be conducted remotely. In-person jobs (and the
need to commute) are skewed toward lower-income households as well as Black and
Latinx communities. For example, only 6% of employees in jobs with an annual income
of less than $40,000 are eligible to work remotely compared to 76% of those in jobs with
an annual income of more than $150,000. Likewise, only 33% of Black workers and 30%
of Latinx workers are employed in jobs where they are eligible for remote work,
5
compared with 51% of White workers.
Regardless of employment sector and remote work eligibility, differences in household
size and access to technology can exacerbate these differences in participation in remote
or in-person work by lower-income households as well as Black and Latinx communities.
Most Tech Workers Have Not Yet Returned to the Office
In Silicon Valley, have started the process of bringing some
employees back to the office through a phased approach that is slated to conclude in early
2022 (see Table 1). For example, Google currently has a voluntary return to the office and
has postponed the mandatory return to the office until January 10, 2022. For Google
employees who return to the office, recent media reports and company blogs indicate
that a hybrid work plan will allow for up to two days of remote work per week.
Additionally, up to 20% of employees may be permitted to work fully remotely with a
salary reduction to reflect cost-of-living differences and the in-
person collaboration. For Intuit, hybrid work arrangements are likely to include up to
5

While there is a hypothesis that the pandemic might shift most office-based employees
to remote work configurations and reduce the number of people working on-site,
academic research, Silicon Valley leadership and unabated development demand in
Mountain View suggest that there is likely to continue to be a strong role for in-person
work and collaboration.
The importance of in-person collaboration and chance encounters in the workplace was
recently highlighted by Sundar Pichai, CEO of Google/Alphabet, as critical to the

technological innovation in the postpandemic era, thereby maintaining the importance
of in-person workplaces alongside a shift to increased levels of remote work.
Researchers at Stanford University also note the limitations of remote work tools such as
videoconferencing for virtual collaboration. These limitations include negative
psychological effects that have been observed in relation to Zoom fatigue, social isolation,
and the pressures of work-life blending in a remote work setting. Along with
collaborative opportunities, these issues of mental health and work-life boundaries are
likely to prompt a return to the workplace for many who could otherwise conduct their
work fully remotely.
Return to Office Plans Will Likely Result in Worse than Prepandemic Traffic
Preliminary information from several Silicon Valley technology companies suggest that
10% to 30% of employees have currently returned to the office. Based on the preliminary
hybrid work plans listed in Table 1, initial postpandemic office-based work may reach
40% to 64% of prepandemic occupancy if most employees continue with remote work
two days per week and some employees are permitted and choose to work fully remotely.
An initial return to the office in early 2022 at 40% to 64% of office capacity would
represent a 100% to 400% increase in travel demand relative to current pandemic rates
for the companies involved.
With current Bay Area vehicle traffic levels of approximately 90% of prepandemic levels
(see Figure 1), a 100% to 400% increase in travel demand for corporate return to office
plans represents substantially higher rates of vehicle traffic than prepandemic levels if
current patterns of transit hesitancy (see Figure 4) persist.
Planned Hot Desk Office Configurations Will Allow Workforce Expansion
A likely scenario is that lower office occupancies associated with increased remote work
will be counteracted by new office configurations that allow for more efficient use of
space. Specifically, in response to increased requirements and demands for social
distancing and remote work, technology companies have accelerated prepandemic
trends toward hot desk office configurations.
Hot desk office configurations have historically been implemented in workplaces with
robust transportation demand management (TDM) programs such as Genentech in South
San Francisco. Such configurations allow companies to make efficient use of office space
when a sizeable portion of the workforce works remotely for some portion of the time.
For example, for the past decade, Genentech has encouraged employees to work from
home one day per week as an employee benefit associated with TDM strategies to meet
Pandemic Travel Patterns and Postpandemic Opportunities
December 1, 2021
Page 12 of 22
freeway on-ramp trip caps. Rather than leaving 20% of desks unutilized when employees
work from home, Genentech offices have been designed with team pods, hot desks, and
conference facilities.
Given the shift toward more robust remote work policies, Google is planning next-
generation COVID-friendly hot desk arrangements for their Mountain View offices.
These arrangements allow for better social distancing through lower-density spacing of
hot desks in team pods to more efficiently utilize facilities.
With these new office configurations and remote work options, it is unlikely that
postpandemic conditions will see underutilization of office spaces. Instead, companies
are finding a way to utilize spaces more efficiently and allow for remote work with team
members using facilities on a rotating basis. Should social distancing become less of a
concern, such reconfigurations of offices into hot desks and team pods will support a
return to prepandemic daily occupancy rates at an existing building spread out over a
higher number of employees. In this sense, hybrid work models are a form of TDM in
that they allow a higher number of employees to work at a building without increasing
the number of daily trips to that building.
From the perspective of the City, remote work conditions at Silicon Valley companies
are, therefore, not expected to result in reduced travel demand relative to prepandemic
levels. Instead, staff anticipates that the conditions will result in workforce expansion
with a similar level of daily trips to prepandemic conditions. If transit hesitancy persists,
higher vehicle trip rates and congestion are expected. This expectation is supported by
the heavy development demand that continues unabated throughout the pandemic.
Higher Rates of Remote Work will Likely Lead to Longer Commutes
Induced travel demand is a phenomenon that has been studied and proven by various
researchers, while controlling for population increase and demographic change. Induced
travel demand is any increase in travel arising from improved travel conditions such
8
as shorter travel times. This phenomenon results in roadways filling up faster than
would otherwise be expected after certain improvements are made. The extent to which
the roadways fill up faster is determined by the elasticity of demand.

Pandemic Travel Patterns and Postpandemic Opportunities
December 1, 2021
Page 13 of 22
Current and potential postpandemic travel improvements that would trigger (or have
already triggered) induced demand effects include:
Opportunities for remote work several days per week, which reduces the total
weekly commute times for all modes;
Reduced traffic congestion and therefore shorter commute times for motorists
during the pandemic;
Projects such as new auxiliary lanes on freeways and new turn lanes on local streets,
which reduce travel delay for motorists; and
Increased availability of free motor vehicle parking near work and other
destinations.
In response to these types of changes, research indicates that travelers change their
behaviors in the immediate, near term, and long term.
In the immediate term, travelers tend to:
Select the most direct route rather than using back routes.
In the near term, travelers tend to:
Select more distant destinations for daily trips instead of living locally;
Add new trips that would otherwise not be taken.
In the long term, travelers tend to:
Make locational investments such as moving to a house in a far-flung area
instead of living in more dense, mixed-use, and transit-oriented areas;
Pandemic Travel Patterns and Postpandemic Opportunities
December 1, 2021
Page 14 of 22
Purchase a second or third car rather than living a car-light lifestyle; and
Develop land or relocate their businesses to more remote areas.
Given the duration of the pandemic, all of these effects have been observed in Silicon
Valley, including long-term real estate investments in more suburban or rural areas such

offices located near transit. As traffic volumes rebound in postpandemic era, a certain
amount of reversal of these patterns can be expected. For example, increased commute
travel and greater flexibility in work conditions is likely to be accompanied by peak
spreadingwith commute patterns spread out throughout the day, and not just in the
peak period.
With the prospect of greater opportunity for more remote work in the postpandemic era,
induced travel demand effects suggest that Mountain View employees will be more likely
to live further away and commute further than in prepandemic times. Given the
geography of California, these locations are likely to be less accessible to transit, thereby
increasing the likelihood that employees drive alone to work (rather than walk, bike, or
use transit) on the days that they do commute. Despite the potential reductions in travel
associated with remote work, the long-term induced travel demand effects could
potentially result in increased rates of single-occupancy vehicle (SOV) travel and
vehicle-miles traveled (VMT) due to the spreading of trip origins and increased rates
of mega-commuting of 50 miles of more.
In Silicon Valley, the phenomenon of mega-commuting includes the following behaviors,
which have been anecdotally reported to City staff by tech sector and other professional
workers:
Vanpool partners who commute from far-flung locations and share the driving.
This type of mega-commuting is more likely to occur when commuters have
consistent daily travel patterns.
SOV mega-commuters who drive alone several times a week from far-flung
residential locations such as Brentwood or Sacramento;
Airplane mega-commuters who commute by airplane between different regions
such as Sacramento, Tahoe, San Diego, Greater Los Angeles, Oregon, Washington,
or Colorado on a daily or weekly basis.

Figure 8: Carbon Footprint of Different Modes of Transportation
As illustrated in Figure 8, mega-commuting on a regular basis by car or airplane is
associated with very high VMT and GHG emissions that have the potential to outweigh
the environmental benefits of less frequent commutes. The more sprawling residential
patterns associated with mega-commuting mean that both commuting and daily travel
patterns are less likely to be accessible by transit and other sustainable modes of
transportation.
In addition to GHG emissions, mega-commuting patterns are also associated with urban
sprawl and higher rates of land consumption, which is, in turn, associated with other
environmental impacts, including increased stormwater runoff, water pollution, soil
erosion, resource consumption, solid waste generation, habitat loss, loss of agricultural
land, and vulnerability to extreme weather events such as wildfires and storms.

Summary: Local Traffic Relief Masks Higher SOV Rates and Potential Postpandemic
Congestion
According to Caltrans data, traffic volumes on freeways in Mountain View are currently
about 5% to 10% lower than in prepandemic times. This moderate traffic relief, however,
masks a number of more concerning patterns, including the following:
There is a significant lag in the recovery of transit ridership relative to vehicle traffic
volumes, which corresponds to lower average vehicle occupancy and high
consumption of motor vehicle lanes.
Most Silicon Valley companies plan to have a majority of employees return to the
office and continue to demonstrate their expectation of face-to-face workplaces with
unabated development activity and plans.
The return to the office for employees from these companies will dramatically
increase the number of people traveling into and through Mountain View.
Companies have accelerated the shift toward hot desk-style office configurations,
which means that more people can use the same amount of office space on a rotating
basis.
The current congestion relief and increased opportunity for remote work is
associated with induced travel demand and induced real estate investment in lower-
density and less transit-accessible areas, which may exacerbate GHG emissions and
traffic congestion concerns when more employees return to the office.
While there is still significant uncertainty about postpandemic travel patterns, the factors
listed above indicate that remote work conditions are not expected to be a sustainable
long-term solution for significantly reducing traffic congestion and VMT in Mountain
View.
DISCUSSION
The City of Mountain View has a multi-pronged array of strategies for reducing SOV
trips, reducing VMT, and encouraging people to shift to more sustainable modes of
transportation.
Pandemic Travel Patterns and Postpandemic Opportunities
December 1, 2021
Page 17 of 22
The City Land Use Plans Provide a Foundation for Transportation Transformation
The City of outlines policies that limit street widening as
a means of improving traffic flow (MOB 3.4 and 10.3) and that encourage a shift toward
more sustainable modes of transportation. The General Plan and Precise Plans for North
Bayshore, San Antonio, East Whisman, El Camino Real, Downtown, and Moffett areas
also encourage a shift from suburban car-oriented travel
patterns to more sustainable transportation patterns, while also protecting key assets
such as habitat areas in the Shoreline Regional Park Community and historic character in
downtown.
These land use plans provide an important foundation for the private market to add
thousands of new market-rate and affordable housing units in Mountain View. Increased
housing supply helps reduce SOV trips and VMT by placing residences within a more
walkable, bikeable, and transit-accessible proximity to jobs and services. For example,
the North Bayshore Precise Plan lays out a plan for adding nearly 10,000 new housing
units in proximity to North Bayshore jobs, with 20% being affordable housing units.
The General Plan and Precise Plans integrate land use planning with multi-modal
transportation investments to address development effects and encourage a shift away
from SOV travel. For example, the Shoreline Boulevard bus lane project is being
implemented to support development within the North Bayshore Precise Plan.
Furthermore, the North Bayshore Precise Plan includes a gateway trip cap with
requirements for measuring the number of cars going in and out of the district every six
months to ensure that the district moves toward its ambitious goal of SOV trip reduction.
Affordable Housing Programs Also Reduce SOV Trips and Average VMT
In addition to long-range plans which facilitate development of new dwelling units, the
City of Mountain View is implementing strategies to preserve the inventory of existing
affordable housing and facilitate new affordable housing development, including
housing for families, seniors, low-wage workers, and developmentally disabled adults.
Low-income housing is particularly helpful for reducing SOV trips and VMT because
lower-income populations have a higher elasticity demand, which means that they are
more likely to respond to efforts to encourage use of modes other than driving alone.
As shown in Figure 9, Mountain View's affordable housing programs are extensive and
distributed across a wide area of the City. These programs include Rent Stabilization
(rent control for units built before 1995); Subsidized Rental Housing (financial assistance
to provide affordable housing), and Below-Market-Rate Housing (developers required to

set aside 15% of all housing units for low- and moderate-income households). There are
currently more than 16,101 affordable dwelling units in Mountain View, including
1,421 subsidized rental apartments and programs for previously unhoused populations,
such as the project Homekey Program.
Multi-Modal Transportation Infrastructure Investments Aim to Create Mode Shift
The City of Mountain View also has key transportation policies and plans that are
These policies
emphasize sustainable transportation modes and provide a framework for shifting away
from SOV trips toward walking, biking, and transit.
Based on priorities outlined in AccessMV, the City is progressively investing in
transportation projects that help to reduce SOV trips and create a path to more
sustainable travel patterns. Projects currently undergoing feasibility analysis, design, or
construction include:
Bus lanes and protected bikeways along Shoreline Boulevard and Charleston Road;
Grade separations at Rengstorff Avenue and Castro Street; and
A pedestrian mall for the 100, 200, and 300 blocks of Castro Street. (This project
draws upon lessons from the Castro StrEATS program, which was implemented to
help facilitate business recovery during COVID while allowing community
members to envision a more walkable downtown.)
In addition to the above projects, the City has been awarded more than $30 million in
grant funding within the last two years for key multi-modal transportation projects,
including:
Pedestrian and bicycle improvements along El Camino Real and Stierlin Road;
A pedestrian/bicycle undercrossing at Bernardo Avenue;
Extension of Stevens Creek Trail; and
Expansion of the Mountain View Community Shuttle service.
All of these investments will help to curb SOV trips by providing attractive alternatives
to driving alone.

City TDM Requirements Encourage Corporations to Do Their Part to Reduce SOV Trips
As employees return to offices, TDM requirements, incentives, and encouragement
programs can play a critical role in helping to shift people out of cars and back to transit
and other sustainable modes.
The City of Mountain View is a regional leader in TDM as exemplified by its cutting-edge
TDM guidelines for the North Bayshore Area. These guidelines support precise plan
goals and provide guidance for developers and corporations to help their employees
walk, bike, and use transit instead of driving alone. Other precise plans, such as the East
Whisman Precise Plan, also include TDM guidelines and requirements for new
development.
The Cityauthority to impose trip reduction requirements and TDM programs is
limited to new development at the time of project approval or entitlement. The City
has been consistently incorporating such requirements in the conditions of approval for
both new commercial and residential developments above a minimum size threshold.
After a project is approved, the City may enforce the trip reduction requirements
included in the conditions of approval; however, the City cannot impose new trip
reduction or TDM requirements. Therefore, efforts and incentives that encourage
voluntary participation in TDM programs by existing commercial and residential
development are essential for shifting people out of SOV travel.
In order to further these TDM efforts, Council has authorized funding for a TDM Analyst,
to be hired in early 2022. The TDM Analyst will help the City to establish a program for
monitoring and achieving compliance with TDM requirements imposed on
developments as a condition of approval. The TDM Analyst will also help to develop a
Citywide TDM ordinance for Mountain View that will establish a more consistent
approach for all new development in the City. The TDM Analyst will also help support
the Transportation Section in Public Works with programs and initiatives for establishing
voluntary TDM programs.
Additional Opportunities to Reduce SOV Trips Postpandemic
There are a number of short- and long-term strategies that the City is pursuing that can
help encourage lower rates of SOV commuting in the postpandemic period as outlined
in Table 2 below.

There are additional strategies to address postpandemic traffic that could be considered;
however, these strategies would require additional staffing and/or budgetary resources.
These strategies include the following:
Augment outreach efforts by transit agencies to encourage increased transit
ridership and carpool and vanpool ridership;
Advocate for expanded transit services serving Mountain View from VTA;
Develop strategies and funding options to expand the fare-free Community Shuttle
services, including the possibility of merging with the fare-free MVgo Shuttle
operated by the Mountain View Transportation Management Association (MTMA);
Increase partnership with the MTMA to explore additional funding sources and
broader delivery of TDM programs; and
Develop or facilitate micro-mobility programs (e.g., e-scooter share).
NEXT STEPS
Staff will continue to monitor the effects of the pandemic on commute travel and other
trips. Staff will also continue to implement the strategies in Table 2. Implementation of
additional strategies or expanded efforts for existing strategies will require Council
consideration as part of the Fiscal Year 2021-22 and Fiscal Year 2022-23 Strategic
Roadmap Action Plan priority projects for commitment of staffing resources and funding.

MEMORANDUM
Public Works Department
DATE: December 1, 2021
TO: Council Sustainability Committee
FROM: Raymond Wong, Senior Project Manager
Lisa Au, Assistant Public Works Director
Dawn S. Cameron, Public Works Director
SUBJECT: Sea Level Rise Planning and Regional Collaboration Efforts
RECOMMENDATION
Receive an update on sea level rise planning and regional collaboration efforts.
BACKGROUND
The City of Mountain View is susceptible to fluvial (river or creek) flooding from
watershed runoff and coastal flooding from high tide and waves from the San Francisco
Bay, especially at the low-lying areas north of U.S. 101 in the North Bayshore Area.
Proper
100-year special flood hazard zone. Flood risk for the area north of U.S. 101 can be
attributed to the following water bodies:
San Francisco Bay from the north which introduces coastal flood risk; and
Permanente Creek and Stevens Creek (including the City storm drain system which
discharges to the two creeks) which introduces fluvial flood risk.
The projected climate change and sea level rise in the San Francisco Bay will increase the
San Francisco Bay water level and coastal flood risk to the northern part of the City.
In 2012, in response to the existing flood risk in the North Bayshore Area and the
anticipated sea level rise flood risk, the City prepared the Shoreline Regional Park
Community Sea Level Rise Study (2012 Study). The study developed a Sea Level Rise
Capital Improvement Program (CIP) to address the existing and the projected Year 2067
Sea Level Rise Planning and Regional Collaboration Efforts
December 1, 2021
Page 2 of 9
coastal flood risk. The CIP consisted of 12 projects, and since that time, staff has been
planning and implementing the CIP based on project priorities and coordination with
other City and regional projects.
In 2018, the California Ocean Protection Council updated the sea level rise estimates and
provided planning resources for coastal communities to develop strategies to address sea
level rise adaptation (Sea Level Rise Guidance 2018). Based on the updated sea level rise
projections and estimates for exceedance probabilities, the low and high ends of the sea
level rise scenarios for the City were updated as follows:
Low Sea Level Rise. Twenty-
High Sea Level Rise. Forty-two
With the new sea level rise protections, staff updated the 2012 Study by reanalyzing sea
level rise impacts to the City and updating the CIP project list. The updated 2021 Sea
Level Rise CIP has 14 projects (Figure 1), with a planning-level program cost estimate of
$121.8 million in year-of-construction dollars ($96.6 million in 2021 dollars) under the
high sea level rise scenario.
Staff presented the update to the City Council on June 22, 2021, and Council directed staff
to use the high sea level rise risk level for the CIP design
criteria. The June 22 Council report is provided as Attachment 1 and contains
background information about sea level rise projections and the updated CIP.

SEA LEVEL RISE STUDY UPDATENEXT STEPS
In the 2021 Sea Level Rise Study Update, staff proposed a number of next steps to plan
and implement sea level rise adaptation for the City. The following lists the next steps
from Attachment 1 and a current progress update for each item.
1. Update the design criteria of the existing Sea Level Rise CIP projects that are
currently in progress based on the 2070 High Sea Level Rise planning scenarios,
where feasible.
Based on the 2012 Study, staff has been implementing sea level rise CIP projects.
The status of each project is summarized in Attachment 1, Table 2. Updates since
the June 2021 report, related to applying the high sea level rise scenario to the
projects, are provided below:
Project 2, Coast-Casey North Levee Improvement
As a part of the South Bay Salt Pond Restoration Project, a draft design for Coast-
Casey North Levee Improvement is being developed by Ducks Unlimited, a project
partner with the California State Coastal Conservancy (CSCC) and U.S. Fish and
Wildlife Services (USFWS). Staff will review the proposed project design to assess
if it meets the updated sea level rise design criteria and update the design criteria as
needed.
Project 3, North Landfill Erosion Protection
This project will use the habitat transition zone that will be established along Pond
A2W and Pond A1, as part of the South Bay Salt Pond Restoration Project, as a base
for the City to continue building up the levee north of the landfill for sea level rise
protection. Staff has begun working on the North Landfill Erosion Protection
project and will use the updated sea level rise design criteria.
Project 6, Lower Stevens Creek Levee Improvements
The draft alternative analysis and preliminary design at the 30% level is completed
based on the design criteria from the 2012 study. With the updated sea level rise
design criteria, the levee will require additional improvements to meet both the
1
freeboard requirements, and stability and seepage design criteria. Staff is
developing an approach to update the alternative analysis and preliminary design,

which will form the basis for environmental permitting, coordination with other
agencies, and engineering design for the project.
Project 9, Sailing Lake Access Road Improvement
Construction activities for this project started in November 2021. This project
focuses on improving the Sailing Lake Access Road located between Sailing Lake
and the Coast-Casey Forebay. The project will improve the safety and reliability of
the Sailing Lake, provide reliable operations and maintenance access, and provide
access and fortify the road in support of the anticipated soil transport for the South
Bay Salt Pond Restoration Project. During the design phase, City staff learned that
the road is actually a dam, due to its location between the two bodies of water with
varying water service elevations, and that the dam falls under the regulatory
jurisdiction of the California Division of Safety of Dams. Since the dam is not
hydraulically connected to the San Francisco Bay, the updated sea level rise design
criteria do not have a direct impact to the project design criteria.
Project 10, Sailing Lake Intake Pump Station Modification
This project is located next to Pond A1 and is currently on hold as the City is
working with the CSCC to first implement the South Bay Salt Pond Project at Pond
A2W. The project is anticipated to restart in 2022. The alternative analysis and
engineering design will be based on the updated sea level rise design criteria.
Project 12, Sea Level Rise Assessment
The project updates the sea level rise assessment presented in Attachment 1. Staff
is currently preparing a technical memorandum to document the sea level rise
projection estimates, flood risk vulnerability, proposed improvements,
implementation plan, detail cost estimate, and budget proposal for each sea level
rise CIP project.
2. For pending and upcoming Sea Level Rise CIP projects, prepare feasibility analysis
and develop performance-based criteria to prioritize the projects and develop an
implementation plan and schedule.
Staff is developing an implementation approach and schedule for the pending
projects listed in Attachment 1, Table 2, and new Projects 11 to 14 recommended in
the 2021 Sea Level Rise Study Update. Staff will conduct additional analyses of these
projects to develop scopes of work and refined cost estimates. Depending on the
Sea Level Rise Planning and Regional Collaboration Efforts
December 1, 2021
Page 6 of 9
timing needs of each project, selected projects will be added for funding
CIP budget preparation.
3. Assess potential changes in long-term groundwater impacts due to sea level rise,
especially the need to revisit its potential effects to the closed landfill operation at
Shoreline at Mountain View.
As part of the operation and South Bay Salt Pond
Restoration Project, there have been studies on the City groundwater system in the
North Bayshore Area. These studies have provided analyses and information to
quantify the existing groundwater condition. Staff is currently evaluating the need to
develop new analyses and studies to assess potential groundwater impacts due to sea
level rise, either as a part of Project 12, Sea Level Rise Assessment and Monitoring, or
as a separate project.
4. Develop recommendations to update the City policy on sea level rise adaptation.
As part of Project 12, Sea Level Rise Assessment and Monitoring, staff will develop
a technical framework to form the basis to recommend updating City policies to take
sea level rise adaptation into consideration by making adjustments on how the City
manages flood risk, infrastructure operations, and land use planning. The Policy
recommendations may affect the City review of proposed developments in the
North Bayshore Area and Shoreline at Mountain View management.
5. Continue to participate and collaborate on regional planning efforts and projects.
Staff has been and will continue to participate and collaborate on regional planning
efforts and projects. Additional information is provided in the Regional
Cooperation section below.
6. Identify additional funding sources for Sea Level Rise CIP implementation.
Staff has been actively identifying and seeking external funding opportunities for
sea level rise project implementation and will collaborate and coordinate with the
to assist with these efforts. Potential external funding
opportunities range from regional grant programs such as Measure AA, Federal
grant programs such as FEMA Hazard Mitigation Grant Program, and cost sharing
in regional collaboration efforts such as the South Bay Salt Pond Restoration Project.
In addition, staff is working with the Valley Water to cost-share the Coast-Casey
North Levee Improvement, as part of the coordination for the Pond A1 component
of the South Bay Salt Pond Restoration Project. Based on input from the City Council
Sea Level Rise Planning and Regional Collaboration Efforts
December 1, 2021
Page 7 of 9
in June 2021, staff will also consider funding sources and collaboration with
businesses and new developments in the City, especially in the North Bayshore
Area.
7. Monitor sea level rise impacts to the City and update the Sea Level Rise CIP in five
years.
This objective is being implemented as a part of Project 12, Sea Level Rise
Assessment and Monitoring, to provide monitoring. Staff started the preparation
this past summer, completed a survey, and established monitoring points along the
existing shoreline levees to monitor levee elevations and long-term subsidence. In
addition, staff is setting up water elevation monitoring at the Mitigation Channel
this winter to monitor water elevation changes and the hydrologic connection
between Mitigation Channel and Pond A2W. Staff will continue to develop a plan
to monitor sea level rise impacts to the City.
REGIONAL COOPERATION
As summarized in the Regional Planning Efforts section of Attachment 1, staff has been
coordinating closely with members of other agencies and working on regional efforts that
In addition to participating in regional
planning efforts such as the San Francisco Bay Regional Coastal Hazards Adaptation
Resiliency Group (CHARG), staff has been working with CSCC, USFWS, and Ducks
Unlimited on Phase II of the South Bay Salt Pond Restoration Project. The project will
restore Pond A1 and Pond A2W to tidal marshes and reestablish tidal flow connection
with South San Francisco Bay by breaching segments of outboard levees. The proposed
gently sloped Habitat Transition Zone will reduce erosion risk along the City shoreline,
which is a vulnerability under anticipated sea level rise conditions.
Listed below is the current status of the Bay Salt Pond
Restoration Project:
Soil Import Permit and LicenseThe City issued an excavation permit and license
agreement in July 2021 to Ducks Unlimited for soil import to the USFWS property
Pond A2W for Habitat Transition Zone construction. Typically, this permit and
license would have been issued after the project itself is fully approved, including
the design plans and agreements, with all regulatory agency permits. However, the
City issued the permit and license in advance of these project milestones to assist in
keeping the project moving forward. Issuing the excavation permit and license
required extensive coordination with Ducks Unlimited, park operations in Shoreline
at Mountain View, other development projects in North Bayshore, and Traffic
Sea Level Rise Planning and Regional Collaboration Efforts
December 1, 2021
Page 8 of 9
Engineering to prepare for and accommodate the large volume of soil import truck
traffic that will impact local traffic and park users.
Project AgreementsStaff is working collaboratively with CSCC and USFWS to
prepare agreements for the full Pond A2W project. The terms of a Memorandum of
Agreement (MOA) and a Habitat Easement Deed and Habitat Maintenance
Agreement (Habitat Agreement) are scheduled for City Council consideration and
approval at the December 14, 2021 Council meeting, pending concurrence from
USFWS. The MOA stipulates the individual project responsibilities for the City and
the USFWS. The Habitat Agreement allows the USFWS to construct part of the
Habitat Transition Zone on City property.
Design PlansThe Ducks Unlimited design team is currently working to finalize
the design plans for Pond A2W. To help move the project forward, City staff
proposed that the City, pending Council approval, design and construct additional
erosion protection along the City shoreline levee at Pond A2W to meet sea level
rise (described under Project 3 previously) and improve the Bay Trail segment
infrastructure. CSCC plans to cost-share some of the improvement costs and will
execute a cost-share agreement with the City.
In addition to the South Bay Salt Pond Restoration Project, staff has also been
coordinating with the United States Army Corps of Engineers (USACE), Valley Water,
the City of Palo Alto, and other agencies on the South San Francisco Bay Shoreline Project
(Shoreline Project) at the Palo Alto Flood Basin. Led by USACE, the project team is
currently working on environmental clearance and studying the feasibility of various
options. The option chosen ; thus,
close coordination is warranted.
Staff is also engaging with neighboring and regional agencies, such as Valley Water, City
of Sunnyvale, NASA Ames Research Center, City of Palo Alto, and San Francisquito
Creek Joint Power Authority, to develop and coordinate sea level rise adaptation plans
and solutions that are consistent across the region and to identify opportunities to
leverage funding and collaboration opportunities.
SUMMARY
Due to climate change and the threats from sea level rise, the City of Mountain View has
been in the forefront of planning and implementing projects to prepare the City for these
changes. These projects are of interest to many stakeholders and have a range of potential
impacts in terms of the environment, wildlife, Shoreline at Mountain View, businesses,

residents, park and trail users, and the closed landfill. The proposed projects and plans
are carefully analyzed to mitigate sea level rise with the needs of the stakeholders. Due
to the size and technical issues associated with the projects, staff has engaged
stakeholders and collaborated with neighboring agencies and regulatory agencies in
planning the project scopes and timing. Staff continues to be involved in regional
planning efforts to seek collaboration, coordinate projects, and identify funding sources
such as grants and cost-sharing opportunities.

BACKGROUND
The City of Mountain View lies on the alluvial plain of Santa Clara Valley with the ground
surface descending from the hills south of the City to the San Francisco Bay (Bay). The
area north of U.S. 101, including the North Bayshore Area, is a low-lying area and is
subject to flooding due to stormwater runoff and high tides and is, therefore, sensitive to
sea level rise impacts (Figure 1).
Even without sea level rise, some properties in the area are within the Federal Emergency
Management -year special flood hazard zone and subject to
special construction and insurance requirements.

North Bayshore AreaExisting Flood Risk
Flood risk for the area north of U.S. 101 is presented from three water bodies: the Bay
from the north, Permanente Creek from the west, and Stevens Creek from the east. Each
is discussed briefly below.
San Francisco Bay
North of Shoreline at Mountain View Regional Park, the City is bounded by three ponds
that were constructed for salt production. One pond (Charleston Slough) was purchased
by the City for wetland restoration. The other two ponds (Pond A1 and Pond A2W) are
owned by the United States Fish and Wildlife Service (USFWS) and are part of the South
Bay Salt Pond Restoration Project (Salt Pond Project) that is being managed by the
California State Coastal Conservancy. Limited coastal flood and sea level rise protection
are provided by the levees that surround these ponds, which are not constructed to the
standards required for certification by FEMA.
The outer (Bay-side) levees will be breached as part of the Salt Pond Project, increasing
Salt Pond Project will
also bolster the levees along Ponds A1 and A2W with installation of a gently sloped
The Habitat
Transition Zone will provide habitat for marsh wildlife as well as wave energy
attenuation that will protect the levees.
Charleston Slough lies between Pond A1 and the Palo Alto Flood Basin (PAFB) and is
protected from the Bay by an outboard levee, with tide gates regulating the flow of Bay
water to the slough. The City has the following three management objectives at
Charleston Slough:
1. Tidal Marsh Restoration: When the City acquired Charleston Slough from the Leslie
Salt Company in 1980, the City inherited a mitigation requirement from the San
Francisco Bay Conservation and Development Commission (BCDC) to restore
53 acres of tidal marsh within the parcel. The restoration effort has been
challenging, and the City is working with BCDC on the effort.
2. Water Supply for the Sailing Lake: The Sailing Lake intake pump station, located at
the southern limit of the slough, provides water supply to the Sailing Lake to
maintain the lake water quality.
2021 Shoreline Sea Level Rise Study Update, Project 21-54

3. Flood Management: The levees along the southern edge of Charleston Slough and
along the western edge of Charleston Slough are low and, therefore, provide limited
protection. The tide gates and levees around Charleston Slough provide some level
of flood protection but are not sufficient under anticipated sea level rise conditions.
The existing floodplain in North Bayshore is connected to the floodplain of the City
of Palo Alto and the PAFB. Therefore, any coastal flood risk management measures
will need to connect and be coordinated with improvements along PAFB in order to
provide continuous protection along the shared shoreline between the two cities.
Permanente Creek
The Permanente Creek levees are not accredited by FEMA, and some areas within North
Bayshore are subject to flooding from Permanente Creek. In recent years,
(formerly Santa Clara Valley Water District) Permanente Creek Flood Protection Project
improved sections of floodwalls and levees along Permanente Creek between U.S. 101
and Shoreline at Mountain View, but additional levee improvements are needed for
anticipated sea level rise conditions.
Stevens Creek
Levees exist on both sides of Stevens Creek from U.S. 101 to Crittenden Lane, protecting
Mountain View to the west and Moffett Field/Sunnyvale to the east. These levees were
accredited by FEMA as providing protection from the 100-year flood event under existing
conditions. Additional improvements are needed for the levees north of Crittenden Lane
that were not accredited by FEMA to protect against existing and anticipated sea level
rise conditions.
2012 Sea Level Rise Study
In 2012, in response to the existing flood risk for the North Bayshore Area and the
anticipated sea level rise risk, the City developed the Shoreline Regional Park
Community Sea Level Rise Study Feasibility report and Capital Improvement Program
report (2012 Study). The 2012 Study proposed a sea level rise planning horizon of Year
2067, projected the future water surface elevations at the Bay with both high and low sea
level rise projections under a 100-year event, estimated the coastal flood vulnerabilities
in North Bayshore, and developed a Sea Level Rise Capital Improvement Program (CIP)
to address the existing and the projected Year 2067 coastal flood risk.

June 22, 2021
Page 5 of 17
Recognizing that there is some uncertainty regarding how much the sea level will rise,
the 2012 Study adopted the following two scenarios to bracket the low and high ends of
the range.
Low Sea Level Rise. Eight inches of sea level rise between 2000 and 2067
(1% (NAVD)).
High Sea Level Rise. Thirty-one inches of sea level rise between 2000 and
2067 (1% NAVD).
The 2012 Study recommended, and Council approved, project implementation based on
-Sea Level Rise CIP projects will be designed
to provide protection from the Low projection (8 of sea level rise) with simple
adaptability to meet the High scenario. For instance, levees would be constructed with a
wider base that can accommodate a future increase in height. Each scenario is shown
diagrammatically in Figure 2.

The Sea Level Rise CIP includes 12 projects to address impacts from sea level rise,
primarily improvements to levees and pump stations (see Table 1). The 2012 estimate
value of the 12 Sea Level Rise projects was $45.7 million.

The North Bayshore Precise Plan incorporated the sea level rise considerations from the
2012 Study into land use planning design guidelines. It includes levee design, storm
drainage improvements, and the minimum finished floor elevation in the low sea level
rise inundation zone to account for sea level rise.

Regional Planning Efforts
Staff has been coordinating closely with members of other agencies working on regional
Phase II of the Salt Pond Project will restore Pond A1 and Pond A2W to tidal marshes
and reestablish tidal flow connection with South San Francisco Bay by breaching
segments of outboard levees. The proposed gently sloped Habitat Transition Zone will
reduce erosion risk along the City shoreline, which is a vulnerability under anticipated
sea level rise conditions. The design of the improvements to Pond A2W is 90% complete,
and staff is working with the Salt Pond project team to complete design, project
agreements, and logistics of hauling a significant amount of soil for construction of the
Habitat Transition Zone. Construction is scheduled to start in summer 2021, with
material hauling through Shoreline at Mountain View to stockpile soil in Pond A2W. The
final design and the project agreements are anticipated to be complete before the end of
2021, which will be followed by full construction work at Pond A2W.
Staff has also been coordinating with the United States Army Corps of Engineers
(USACE), Valley Water, the City of Palo Alto, and other agencies on the South San
Francisco Bay Shoreline Project (Shoreline Project) at the PAFB. Led by USACE, the
project team is currently working on environmental clearance and studying the feasibility
area, so close coordination is warranted.

ANALYSIS
Since 2012, projections for sea level rise have been updated and regional planning efforts
have progressed.
Updated Sea Level Rise Scenarios
State of California Sea-
Level Rise Guidance 2018 Update (OPC 2018 Guidance) provides new estimates and
planning resources for coastal communities to develop strategies to address sea level rise
adaptation.
2021 Shoreline Sea Level Rise Study Update, Project 21-54
June 22, 2021
Page 10 of 17
The OPC 2018 Guidance projected a 66% probability that the sea level rise in Year 2070
will be at or below 23 and considered this to be a low risk aversion scenario. It also
projected a 0.5% probability that the sea level rise in 2070 will be at or above 42 and
considered this to be a medium-to-high risk aversion scenario. The increased sea level
rise projection is a reflection of the increasing rate of ice loss from Greenland and the
Antarctic ice sheets, improved scientific understanding and modeling of sea level rise,
and change in sea level rise with consideration of different greenhouse gas emissions
scenarios.
Based on the updated sea level rise projections and their estimated exceedance
probabilities, the low and high ends of the sea level rise scenarios are updated as follows:
Low Sea Level Rise. Twenty-three inches of sea level rise between 2000 and
2070 (1% sti
2012 Study: Eight inches of sea level rise between 2000 and 2067 (1% still water
level
High Sea Level Rise. Forty-two inches of sea level rise between 2000 and 2070
(1% NAVD).
2012 Study: Thirty-one inches of sea level rise between 2000 and 2067 (1% still
NAVD).
With the latest projections, the planning year has been updated from 2067 to 2070, which
equates to an approximately 50-year planning horizon and is in line with the sea level
rise projection time steps presented in the OPC 2018 Guidance.
Updated Sea Level Rise Study
2019 Storm
Drain Master Plan
Study by reanalyzing sea level rise impacts to the City and updating the CIP project list.
In this sea level rise study update, it is assumed the Salt Pond Project will proceed as
planned, but the analysis did not include implementation of the regional Shoreline
Project (unless noted) due to the uncertainties related to that project scope, timing, and
funding.
The sea level rise study update mapped the 100-year coastal floodplain under existing
conditions and the two projected sea level rise scenarios (Figure 3). Based on this new
2021 Shoreline Sea Level Rise Study Update, Project 21-54
June 22, 2021
Page 11 of 17
analysis, the scope and cost estimate of each project in the 2012 Study are updated under
two scenarios:
Low-Plus Sea Level Rise Scenario: Improvements to provide 100-year flood
protection with 23 of sea level rise by Year 2070, but with a wider levee base sized
for the high sea level rise scenario so additional fill can be more easily added at a
later time.
High Sea Level Rise Scenario: Improvements to provide 100-year flood protection
with 42 of sea level rise by Year 2070.

Page 13 of 17
The updated 2021 Sea Level Rise CIP projects are shown in Figure 4 and Table 3. In
general, the updated Sea Level Rise CIP has a similar list of projects, but the scope of
work has increased for most projects due to the higher sea level rise projections and
design elevations. Construction cost estimates have increased accordingly. Two new
projects have been added, and additional modifications to the scopes of some projects are
made, as described below.
Project 11: Charleston Slough Tide Gate Improvement is updated, and the scope of
work will be expanded to include the mitigation requirements to meet the BCDC
tidal marsh vegetation requirements in Charleston Slough. Project 11 will be
Charleston Slough Mitigation Project
Project 12: Sea Level Rise Assessment and Monitoring is updated to include an
important element to monitor sea level rise impacts to the North Bayshore Area and
City infrastructure and will develop a series of performance-based criteria to plan
and schedule the implementation of specific Sea Level Rise CIP projects.
A new Project 13: Crittenden Pump Station Improvement is added. Based on
recommendations from the 2019 Storm Drain Master Plan, this project will
decommission the Charleston Pump Station and route stormwater flow from the
Charleston Detention Basin to Crittenden Pump Station. This project will improve
the interior drainage system and provide a single discharge to Stevens Creek.
A new Project 14: As-needed Storm Drain Improvements is added. This project
provides as-needed interior drainage improvements, such as backflow prevention
at the creek outfalls to address potential sea level rise impacts.
The updated 2021 Sea Level Rise CIP planning level program cost estimate in 2021 dollars
is as follows:
Low-Plus Sea Level Rise Scenario = $86.7 million
High Sea Level Rise Scenario = $96.6 million

The sea level rise projection has been trending up with each revision. Research in
this field will continue, and staff does not anticipate that estimates will be reduced.

Staff will continue to cooperate with other agencies that are studying or implementing
projects associated with sea level rise to ensure common analysis and develop cost-
effective solutions for the City and other agencies.
NEXT STEPS
Staff proposes the following next steps for sea level rise planning for the City:
Update the design criteria of the existing Sea Level Rise CIP projects that are
currently in progress based on the 2070 High Sea Level Rise planning scenarios,
where feasible.
For the pending and upcoming Sea Level Rise CIP projects, prepare feasibility
analysis and develop performance-based criteria to prioritize the projects and
develop an implementation plan and schedule.
Assess potential changes in long-term groundwater impacts due to sea level rise,
especially the need to revisit its potential effects to the closed landfill operation at
Shoreline at Mountain View.
Develop recommendations to update the City policy on sea level rise adaptation.
Continue to participate and collaborate on regional planning efforts and projects.
Identify additional funding sources for Sea Level Rise CIP implementation.
Monitor sea level rise impacts to the City and update the Sea Level Rise CIP in five
years.
FISCAL IMPACT
This study does not have an immediate financial impact. However, it is anticipated that
over the ensuing years, it may be necessary to issue long-term debt to fund a number of
significant capital projects. Individual projects are CIP.
The recommended updated list of Sea Level Rise CIP projects is estimated to cost
$121.8 million in year-of-construction dollars. Of this amount, $11 million is currently
funded in the CIP. Although staff will continue to seek outside funding sources and
partnering opportunities, it is anticipated that the Shoreline Regional Park Community
Fund will be the primary source for the remaining $110.8 million required to complete
the projects.

CONCLUSION
The 2021 Shoreline Sea Level Rise Study Update provides a framework to plan the
projects required to manage the flood risk to the City due to projected sea level rise.
Under the High Sea Level Rise scenario, the overall planning level program cost is
estimated at $96.6 million in present value ($121.8 million in year of construction dollars).
While there are opportunities to reduce the City share via collaboration with regional
projects, cost-sharing, and grant funding, there are uncertainties on these funding
sources. There are also uncertainties associated with sea level rise planning, including
the projection and timing of sea level rise, scope, funding, and timing of regional projects
that
Coordination with other agencies is essential because the coastal floodplain in North
Bayshore is connected across jurisdictional boundaries. Staff will continue to implement
projects that are under way, prioritize and recommend projects for funding as
appropriate, and continue to seek outside funding sources and partnering opportunities.

MEMORANDUM
DATE: December 1, 2021
TO: Council Sustainability Committee
FROM: Lauren Anderson, Sustainability Analyst II
Steve Attinger, Sustainability Coordinator
VIA: Audrey Seymour Ramberg, Assistant City Manager/Chief Operating
Officer
SUBJECT: Sustainability Action Plan 4 Status Update
PURPOSE
This memorandum presents a status update on Sustainability Action Plan 4 (SAP-4),
including progress since the May 2021 update to City Council and a preview of significant
upcoming items.
RECOMMENDATION
Provide input to staff based on this SAP-4 status update.
BACKGROUND
The City Council adopted an original Environmental Sustainability Action Plan (ESAP)
in March 2009, for Fiscal Years 2008-09 through 2010-
short- and long-term sustainability goals. In April 2012, Council adopted Environmental
Sustainability Action Plan 2 (ESAP-2) for Fiscal Years 2011-12 through 2013-14. In 2015,
Council adopted a communitywide Climate Protection Roadmap and Municipal
(GHG) reduction targets through 2050. In September 2016, the Council adopted
Environmental Sustainability Action Plan 3 (ESAP-3) for Fiscal Years 2016-17 through
2018-19.
In October 2019, the City Council adopted Sustainability Action Plan 4 (SAP-4) as the
for Fiscal Years 2019-20
Sustainability Action Plan 4 Status Update
December 1, 2021
Page 2 of 8
through 2021-22. Among its 81 new actions and 79 already-approved actions, SAP-4
contains smaller projects that provide near-term GHG reductions and larger, longer-term
infrastructure projects that will yield significant GHG reductions over time. SAP-4
actions are organized around 27 high-level goals in the transportation, energy, land use,
zero waste, water, parks and ecosystems, and core sustainability sectors. In May 2021,
staff updated the City Council on the status of SAP-4 implementation. During this
update, Council approved the removal of five actions (because they were no longer
needed or could be combined with other actions) and allocated the available balance
within the Sustainability Fund to support several projects. (The Sustainability Fund was
created when the City Council adopted SAP-4 in October 2019.)
ANALYSIS
Overview of SAP-4 Status
As shown in Table 1, staff has made progress implementing many SAP-4 actions; 75% of
actions are completed or in progress, while 25% of actions have not been started.
Table 1: Progress of 76 New SAP-4 Actions
STATUS NUMBER PERCENT
Completed 15 20%
In Progress/Ongoing 42 55%
Not Started 19 25%
Total New Actions 76 100%
Although many actions have progressed as intended, others have been delayed by the
COVID-19 pandemic and associated impacts. These impacts have included: Shelter-in-
Place orders that temporarily restricted work on capital projects; emergence of new
priorities to respond to community needs related to the pandemic; constraints on the
availability and resources of stakeholders and potential partners as they focused on
COVID-19 recovery; staff vacancies in existing positions and challenges in hiring new
SAP-4 positions; and reduced capacity and resources as staff focused on maintaining City
services in compliance with public health restrictions.

Page 3 of 8
Key Progress Since May 2021
Many SAP-4 projects have started, advanced significantly, or been completed since the
update to the City Council in May 2021, as described below.
Complete final 2018 community GHG inventory (S2.5)
The final 2018 and preliminary 2019 community greenhouse gas inventories were
presented to the City Council on June 22, 2021. Emissions declined between 2017 and 2018
and remained below 2005 baseline inventory levels. Final 2018 emissions were 604,318 MT
COe, slightly lower than estimated in the preliminary 2018 inventory (610,226 MT COe),
22
due to lower emissions from energy, solid waste, and off-road mobile sources.
Run the Cool Block program in Mountain View neighborhoods (S4.5)
While COVID-19 prevented a full launch of the Cool Block program in early 2020, two
groups were able to complete the program virtually in fall 2020. In October 2021, staff
held three well-attended information sessions toward a second launch. Cool Block leader
trainings occurred in November and will continue in December, and the program will
officially relaunch in January 2022.
Develop rebate program for e-bikes and other mobility devices (T3.6)
Staff is finalizing the parameters of an electric bike incentive program and is evaluating
options for program administration. Staff expects to launch the program in spring of
2022.
Develop an Electric Vehicle Action Plan (T7.4)
The Electric Vehicle Action Plan (EVAP) is substantially complete and will be finalized
by the end of 2021. The EVAP is a high-level plan identifying strategies, policies, and
programs to support electric vehicle adoption and infrastructure deployment. The
actions outlined in this plan will be integrated into the next Sustainability Action Plan.
Evaluate a trade-in or rebate program for landscaping equipment (P3.2)
Staff has been working with Silicon Valley Clean Energy (SVCE) and other member
agencies to evaluate the potential of implementing a regional incentive program for
electric landscaping equipment. While several other agencies are interested in promoting
electric landscaping equipment, none currently have the funding or staff capacity to
Sustainability Action Plan 4 Status Update
December 1, 2021
Page 4 of 8
implement an incentive program. SVCE has agreed to implement a pilot program in
Mountain View, with the hope of expanding it to other cities in the future. Staff plans to
launch the incentive program by spring 2022.
Develop a sustainability dashboard for the City's website (S3.3)
Staff has identified a platform that offers the features needed to deploy a sustainability
dashboard on and is evaluating its usability and other details. Table 2
shows a preliminary list of metrics proposed by staff to display on the dashboard. These
metrics may change slightly before the dashboard is completed. Depending on the
complexity of displaying the metrics, staff may roll them out in a phased approach. Staff
will gather the data starting in early 2022 and seek community feedback before launching
the dashboard City-wide, and hopes to release a first version by spring/summer of 2022.

To provide residents with customized information about switching to electric appliances,
installing solar energy, and selecting appropriate electric vehicles and bikes, staff plans
to launch the online Electrify Mountain View platform by late 2021 or early 2022.
Develop a resolution and outreach in support of a plant-based diet (S4.7)
In summer 2021, staff launched an informational campaign that has featured several
webinars promoting plant-based eating. Staff is currently designing a restaurant
engagement program and is evaluating options to increase plant-based eating within City
operations. Staff plans to present a program proposal to the City Council by March 2022.
Community Services Department
Update the Community Tree Master Plan (P2.2)
Staff is reviewing the tree canopy and land cover data produced by certified arborists on
contract with the City. Staff is also assessing current ordinances, guidelines, and
standards; s; and drafting updates needed to address
tree diversity, management, and goals. The public input portion of the Community Tree
Master Plan (CTMP) update is on hold as staff considers how biodiversity influences and
connects to various master plans, including the Community Tree Master Plan, active
transportation plans, the Parks and Recreation Strategic Plan, and wildlife/Shoreline
plans. Staff expects to complete the update by October 2022.
Partner with Canopy to expand tree planting and outreach (P2.3)
The City completed its first full year contract with Canopy in July 2021, through which
21 trees were planted over the course of three planting events. Canopy is a nonprofit
organization focused on tree planting and stewardship, education, and advocacy. The
City recently renewed the contract with Canopy and held a tree planting and tree care
work day in Mountain View in November 2021.

Expand use of electric landscaping equipment and test new models (P3.1)
Staff recently purchased an additional $10,000 of electric landscaping equipment,
including back-pack leaf blowers, for various Parks and Roadway crews to use. About
10% of the landscaping work undertaken by Parks and Roadway crews is completed
using electric landscaping equipment. Going forward, staff will replace any broken gas-
powered equipment with electric versions. No new gas-powered blowers or trimmers
will be purchased.
Conduct a communitywide irrigation audit (W1.3)
Staff has finalized a contractor agreement for a communitywide irrigation audit project.
The contractor began the audit in November 2021.
Public Works Department
Analyze opportunities for electrification during renovations (B4.1)
Staff continues to investigate electrification opportunities for all planned City-owned
facilities projects. As such, an electrification evaluation was conducted for City Hall,
Center for the Performing Arts, and Fire Station No. 1. Based on this evaluation, staff
determined that the HVAC system at Fire Station No. 1 should be converted to all-
electric. This electrification work is anticipated to be completed by the end of January
2022. The new Rengstorff Aquatics Center will also be an all-electric facility, including
the water heating for the pools. This project is scheduled to begin construction in early
2022.
Create dedicated funding for active transportation outreach (T3.1)
Various outreach events were cancelled due to COVID-19. A portion of the funding was
used for COVID-19 active transportation outreach (such as Castro StrEATS and touchless
pedestrian push buttons). Outreach activities are also planned or under way for bikeway
implementation via the repaving of Middlefield Road, from Moffett Boulevard to North
Whisman Road.
Develop a bike rack request program (T3.5)
The bike rack request program has been delayed due to staffing shortages; however,
public input has been obtained via the Bicycle/Pedestrian Advisory Committee for a bike
rack project funded by the Transportation Fund for Clean Air (TFCA) program. SAP-4
provided City matching funds to leverage the $70,000 TFCA grant. With this money, the

Implement Food Ware Packaging Reduction Phase 1 measures from the Zero Waste Plan (Z1.2)
Staff is implementing Phase 1 of the Food Ware Packaging Reduction measures from the
These initiatives are designed to address the landfilled waste,
litter and ocean pollution, and potential negative health impacts of single-use food ware.
As part of this effort, staff developed a Food Ware Packaging Reduction Plan,
participated in regional efforts to align and expand food-ware ordinances and share best
practices, drafted a recommended Food Service Ware Ordinance, and received business
and community input. The Food Service Ware Ordinance was considered by the City
Council for a first reading at a public hearing on November 9, 2021, was approved by
Council and will be presented for adoption on December 14. If adopted, these new
regulations would take effect on January 1, 2023. This ordinance expands the current ban
on polystyrene foam food service ware to other types of single-use plastics, and require
that all nonreusable food service ware (plates, bowls, cups, containers, etc.) be
compostable fiber and certified free of per- and polyfluoroalkyl substances (PFAS) or
made entirely of aluminum, which is recyclable. Additionally, the ordinance prohibits
the use of straws, stirrers, toothpicks, and food picks made from, or packaged in, plastic.

the consumer, beginning January 1, 2022.

adoption, many actions have been completed, but others have been delayed or modified
due to COVID-19 or staffing constraints. Since the sustainability landscape is constantly
evolving, staff will continue to provide updates to the Council Sustainability Committee,
as appropriate, so that it may assess the progress of initiatives and recommend
modifications. Staff will present a final update on SAP-4 implementation to the City
Council in fall 2022. Development of Sustainability Action Plan 5 will begin by summer
2022.
