ENVIRONMENTAL REVIEW
Staff will provide an overview of the following chapters at the meeting:
• Visual Quality (pages 3.3-1 through 3.3-56)
• Biological Resources (pages 3.9-1 through 3.9-32)
• Cultural Resources (pages 3.8-1 through 3.8-29)
The comments on these chapters should be focused on whether the information presented in the
Draft EIR adequately covers the environmental impacts that could result from the proposed SUMC
Project. The hearings are not meant to provide a forum for dialogue about the project merits, but to
be opportunities to collect comments on the Draft EIR to ensure that it adequately describes the
environmental impacts of the Project.
1. Visual Quality
Visual Quality impacts are addressed in Section 3.3 of the Draft EIR. Visual quality pertains to how
people see and experience the environment, particularly its visual character. William Kanemoto and
Associates prepared visual simulations analyzed in the chapter.
Significance Thresholds
Based on significance thresholds determined by the City of Palo Alto, the SUMC Project would
result in a significant visual quality impact if it would:
• Substantially degrade the existing visual character or quality ofthe site and its surroundings;
• Significantly alter public viewsheds or view corridors or scenic resources (such as trees,
outcroppings or historic buildings along a scenic roadway);
• Require substantial terrain modifications that would degrade the visual character of the site;
• Allow for new development that would violate existing Comprehensive Plan policies
regarding visual resources;
• Create a new source of substantial light or glare which would adversely affect day or
nighttime views in the area; or
• Substantially shadow public open space (other than public streets and adjacent sidewalks)
between 9:00 a.m. and 3:00 p.m. from September 21 to March 21.
Key Impacts and Mitigations
The following impacts have been identified as significant (S); however the impacts identified in this
chapter can be eliminated through mitigation. The mitigation measures developed for each of the
impacts are identified below.

• VQ-3: Alteration of public viewsheds (S).
• VQ-5: New sources oflight and glare (S).
Mitigation Measure -
Discussion
o VQ-2.l: Compliance with the City's Architectural review process and
recommendations.
Significance determinations for the impact analysis are based on the extent of changes in the visual
character and quality of the SUMC Sites and surroundings, as well as the change in quality of views
from key vantage points. Changes in visual character are affected primarily by building scale, height,
and mass. Landscaping, lighting, exterior architectural treatments, and materials are also considered
in determining the resulting character and its compatibility with surrounding development. Context
and expectations are also considered.
To demonstrate potential impacts from the SUMC Project, visual simulations of existing and
representative post-construction (2025) views from five selected vantage points were prepared.
Figure 3.3-7 of the Draft EIR provides a map of the vantage points.
The SUMC Project would increase on-site massing by adding 1.3 million square feet of building
floor area and raising maximum building height on the SUMC sites from five to seven stories,
reconfigure on-site layout, alter on-site landscaping and lighting, and incorporate new building
materials and treatments.
Mitigation requires the SUMC Project sponsors to submit final building and site plans to the ARB
prior to issuance of any development permits. Architectural Review shall assess the appropriateness
of proposed demolitions, proposed building heights and massing, siting of buildings and structures,
architecture and fa9ade treatments, landscaping, circulation plans, and parking. The ARB may
require alterations to any of the above proj ect features, or the ARB may suggest new features, such as
new landscaping or public art, to improve the proposed SUMC Project design. Any
recommendations made by the ARB with respect to the design of the SUMC Project shall be
implemented by the SUMC Project sponsors.
At the P&TC and City Council meetings the applicant will be providing an overview of the SUMC
Project design, including an animation to provide the Council, P&TC and community an
understanding of each of the Project components, their respective building design intent and how the
different components of the Project tie together.
2. Biological Resources
Biological Resource impacts are addressed in Section 3.9 of the Draft EIR.
Significance Thresholds
Based on significance thresholds determined by the City of Palo Alto, the SUMC Project would
result in a significant biological resource impact if it would:
City of Palo Alto Page 3
• Have a substantial adverse effect, either directly or through habitat modifications, on any
species identified as a candidate, sensitive, or special status species in local or regional plans,
policies, or regulations;
• Have a substantial adverse effect on any riparian habitat or other sensitive natural community
identified in local or regional plans, policies, or regulations, including federally protected
wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to,
marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or
other means;
• Interfere substantially with the movement of any native resident or migratory fish or wildlife
species or with established native resident or migratory wildlife corridors, or impede the use
of native wildlife nursery sites;
• Result in a substantial adverse effect to any "protected tree" as defined by the City of Palo
Alto's Tree Preservation Ordinance (Municipal Code Section 8.10); or
• Conflict with any applicable habitat conservation plan or natural community plan.
Key Impacts and Mitigations
The following impacts have been identified as significant (S); however these impacts can be
eliminated through mitigation. The mitigation measures developed for each of the impacts are
identified below.
• BR-l: Impacts on special-status plant or wildlife resources (S).
Mitigation Measures-
o BR -1.1: Conduct a pre-demolition survey;
o BR-1.2: Avoid roosting areas:
o BR -1.3: Develop and employ bat nest box plan;
o BR-1.4: Avoid tree removal during nesting season:
o BR-1.5: Protect Cooper's hawk in the event of nest discovery.
• BR-3: Use of native wildlife nursery sites (S).
Mitigation Measures-
o BR-3.l: Avoid tree removal during nesting season;
o BR-3.2: Protect birds in the event of nest discovery.
Significant and Unavoidable Impacts
The following impacts have been identified as significant and unavoidable (SU) even after
implementation of mitigation measures:
• BR-4: Result in a substantial adverse effect on any protected tree (SU).
• BR-9: Cumulative impacts on protected trees (SU).
MitigatIOn Measures----------------
o BR -4.1: Prepare a tree preservation report for all trees to be retained;
o BR-4.2: Prepare a solar access study of short and long term effects on protected oaks:
o BR-4.3: Prepare a tree relocation feasibility plan for any protected tree proposed for

Discussion
relocation and retention;
o BR-4.4: Provide a tree preservation bond/security guarantee:
o BR -4.5: Provide optimum tree replacement for loss of publicly-owned trees regulated
tree category.
o BR-4.5: Implement minor site modifications to preserve biologically and
aesthetically significant protected trees.
Approximately 1,562 trees have been identified in the SUMC sites. Coast live oaks and coast
redwoods above a certain size are regulated under the City's Tree Protection and Management
Regulations, which prohibit the removal of these trees, except under limited circumstances. There
are 176 trees large enough to be designated as Protected Trees. 71 Protected trees appear to be within
or sufficiently close to new building footprints or areas associated with the site reconfiguration.
Therefore, removal of up to 71 Protected Trees out of a total of 176 Protected Trees may occur.
Ofthe 71 Protected Trees, approximately 23 trees have been determined by the City to have both
biological and aesthetic resource characteristics. A "Biological Tree Resource" is a protected
category oak or redwood of a certain size as defined in the Palo Alto Municipal Code, Chapter 8.10,
Tree Preservation and Management Regulations. An "Aesthetic Tree Resource" is a Protected Tree
that is deemed important relative to the SUMC Project, as designated by the Department of Planning
and Community Environment or the City Council, because it has one or more of the following
qualities: functions as an important or prominent visual feature; contributes to a larger grove or
landscape theme; and/or possesses unique character as defined in the designation of Heritage Trees
(per Municipal Code Section 8.10.090).
The City has determined that these 23 Protected Trees that are both biologically and aesthetically
significant would require retention and preservation under the SUMC Project. The 23 Protected
Trees include: nine Protected Trees in Kaplan Lawn (located between Pasteur Drive), 12 Protected
Trees in the area ofthe proposed SoM FIM 1 building, one Protected Tree located between the site of
the Blake-Wilbur Clinic building and Welch Road, and one Protected Tree east of the new LPCH
hospital building, along Welch Road.
The new "Hospital District" would create a procedure to permit the removal of the remaining
approximately 48 Protected Trees while preserving the 23 Protected Trees that are considered both
biologically and aesthetically significant. Site planning adjustments could be made to protect some of
the 23 trees, but not all. Therefore, the impact is considered significant and unavoidable.
Tree Preservation Alternative
In an effort to retain as many Protected Trees as possible, the applicant has worked collaboratively
with staff to develop the Tree Preservation Alternative. Section 5 of the Draft EIR describes fully the
Project Alternatives. Although the Alternatives will be di~cus_sed ingreaterd~tail at the luly_IP&TC
meeting and July 26 City Council meeting, it is important to briefly discuss the Tree Preservation
Alternative in context with the Visual Quality and Biological Resources Chapters of the Draft EIR. A
description ofthis Alternative can be found in the Draft EIR on pages 5-15 through 5-22 and Figure
5-1 provides a site plan for this Alternative.
City of Palo Alto PageS
The Tree Preservation Alternative preserves biologically and aesthetically significant oak trees
located in the portion of the SUMC Project known as Kaplan Lawn, outside the proposed FIM 1
building near Pasteur Drive, and outside the new hospital building near Welch Road. The Tree
Preservation Alternative maintains the same square footage and programmatic functions as the
SUMC Project, but proposes design modifications to the new hospital building as well as FIM 1 to
accomplish additional tree preservation. The key difference under the Tree Preservation Alternative
is that the square footage and programmatic functions planned for the hospital module located within
the Kaplan Lawn (Hospital Module Six) would be incorporated into the other hospital modules. The
new design reduces the building footprint and allows all of the trees within the Kaplan Lawn to be
retained. Other changes are proposed to FIM 1 to preserve additional trees.
The Tree Preservation Alternative represents how the project design has changed from the original
application and how it continues to evolve throughout the public review process. The applicant has
identified this Alternative as their preferred alternative and has been working on further developing
the design shown in this Alternative with their Boards of Directors and with the Office of Statewide
Health Planning and Development (OSHPD). The refined SHC and FIM 1 building designs depicted
in the Tree Preservation Alternative, are the designs being supported by Stanford, being reviewed by
ARB and will be the designs presented for consideration after the EIR certification.
The applicant will be providing an overview of the Project design at both the P&TC and City
Council meetings to show how the project design continues to evolve based on information
presented in the Draft EIR (such as the impacts on visual quality and biological resources).
3. Cultural Resources
Cultural Resource impacts are addressed in Section 3.8 of the Draft EIR. This section of the EIR is
based primarily on the report titled Cultural Resources and the Stanford University Medical Center
Facilities Renewal and Replacement Project, prepared by Stanford University and a peer review of
that report prepared by Architectural Resources Group, Inc. (ARG).
Significance Thresholds
Based on significance thresholds determined by the City of Palo Alto, the SUMC Project would
result in a significant cultural resource impact if it would:
• Cause a substantial adverse effect (as defined in CEQA Guidelines section 15064.5(b)) on an
historical resource listed or eligible for listing on the National and/or California Register, or
listed on the City's Historic Inventory;
• Eliminate important examples of major periods of California history or prehistory;
• Cause damage to an historic or unique archaeological resource as defined in Section 15064.5
of the CEQA Guidelines;
----.-Bisturb-Native Am~rican-human-remains, inc1udirrg those interred outside-of fannal
cemeteries;
• Directly or indirectly destroy a unique paleontological resource or site or unique geologic
feature; or

• Directly or indirectly destroy a local cultural resource that is recognized by City Council
resolution.
Key Impacts and Mitigations
The following impacts have been identified as significant (S); however these impacts can be
eliminated through mitigation. The mitigation measures developed for each of the impacts are
identified below.
• CR-2: Impacts on prehistpric or archaeological resources (S).

Discussion
City of Palo Alto Page 7
Seven potential historic resources within the SUMC Sites were evaluated: Governor's Avenue,
Hoover Pavilion, Nurse's Cottage at Hoover Pavilion, 701 Welch Road, 703 Welch Road, 1101
Welch Road, and the Stone Building complex (including the East, West, Core, Boswell, Grant,
Alway, Lane, and Edwards buildings).
The Hoover Pavilion exemplifies the distinctive characteristics of a pre-World War II hospital and
appears to maintain sufficient integrity for listing on the California Register of Historic Resources
(CRHR). The Hoover Pavilion is considered to be an historical resource for purposes of the City's
CEQA analysis.
The Draft ErR concludes that no significant interior spaces remain intact from the period of
significance, exterior modifications would retain significant character defining features and eliminate
non-historic elements, and the proposed medical office building and parking structure retain
significant views and would not result in an adverse, material alternation of significant characteristics
and would result in a less-than-significant impact. Mitigation measures are included to protect the
Hoover Pavilion during construction.
the Stone Building complex was designed by Edward Durell Stone and the landscaping was
designed by Thomas Church. Additionally, the complex is associated with the first heart transplant in
the U.S. Although there have been some alterations to the complex's courtyards and the surrounding
setting; the complex as a whole is largely intact and conveys the original design intent. In addition,
the main entry facades and several architectural elements retain a high degree of integrity and convey
an expression of Stone's work during an important phase of his career. Additionally, enough time
has passed to understand the significance of the heart transplant that occurred at the hospital, and that
the building retains sufficient integrity for association with that time period. Therefore, the Draft
EIR concludes that the Stone Building complex appears eligible for listing on the CRHR and
therefore is an historical resource pursuant to CEQA. The demolition of the Stone Building complex
would result in a significant impact on an historical resource. Mitigation measures CR -1.2 through
CR-1.4 would reduce impacts due to the loss ofthe Stone Building complex; however, the impact
would remain significant and unavoidable.
In combination with the SUMC Project, cumulative development would have cumulatively
significant impacts on historic resources in the City because these would together result in loss of at
least one historically significant structure. Only one other E.D. Stone building in Palo Alto, the Palo
Alto Main Library retains sufficient integrity to be eligible for listing. The demolition ofthe Stone
Building complex would comprise a considerable loss of an historical resource that is a unique and
non-renewable member of a finite class. The demolition ofthe Stone Building complex would have a
cumulatively considerable impact due to the small body ofE.D. Stone's work present in the City that
retains sufficient integrity to be eligible as historicaL resources.
Due to the demolition of the Stone Building complex, the SUMC Project's contribution would
n -remam cumulativelycon.siderable, as this impact cannot be avoided. Implementation of Mitigation
Measures CR -1.2 through CR -1.4 would reduce the SUMC Project's contribution to the cumulative
impact, but not to a less than cumulatively considerable level.

NEXT STEPS
The P&TC will conduct a meeting on June 16 to review the Transportation Chapter and a meeting on
June 23 to review Climate Change and Air Quality. The City Council will review these three topics
on July 12.
Subsequent to public testimony and P&TC and Council comments, along with the written comments
submitted on the Draft EIR during the 69-day public review period, the EIR consultant and staff will
prepare a Final EIRlResponse to Comments. The timing of this document is dependent on the
number of comments received. However, the goal is to complete review of this Project and the EIR
by the end of2010.
Following preparation of the Final EIRIResponse to Comments document, the P&TC will conduct a
public hearing(s) on the Final EIR and provide a recommendation to the City Council. The City
Council will then review the Final EIRlResponse to Comments for action.

The intent of the plan is to aesthetically improve portions of the
project site that would remain unimproved for an extended period
and screen the construction zone from view by passersby along
the public streets and sidewalks. Possible improvements in the
plan include, but are not limited to, the following:
a. The SUMC Project sponsors shall conceal staging areas with
fencing material to be approved by the Planning Director
prior to commencement of use of the staging area for
construction equipment and vehicles.
b. The SUMC Project sponsors shan frequently remove
construction debris and refuse from the SUMC Sites.
c. The SUMC Project sponsors shall install all landscaping as
early as feasible to decrease visual impacts of construction.
Existing landscaping within the SUMC Sites that would not
be removed by the construction shall be maintained.
MITIGATION MEASURE. Mitigation Measure VQ-2.1, below, requires and
ensures compliance with ARB recommendations for final design. Such
compliance would ensure that impacts on on-site visual character and
quality would be less than significant because the ARB's recommendations,
through the Architectural Review process, would address massing, layout,
landscaping, and architectural design impacts from the SUMC Project, as
described further below.

Mitigation Measures
MITIGATION MEASURES. Given the magnitude of the SUMC Project's
infersection impacts, there is no single feasible mitigation measure that can
reduce the impacts to a less-than-significant level. However, there are a
range of measures that, when taken individually, would each contribute to a
partial reduction in tbe SUMC Project's impacts. When combined, these
measures could result in a substantial reduction in the SUMC Project's
impacts.
Under all combinations of feasible mitigation measures below, impacts of
the SUMC Project on intersection LOS would remain significant and
unavoidable. Of all of the feasible combinations, the one that would have
the largest reduction in impact, and that mitigates the greatest number of the
intersection impacts, is the combination of traffic adaptive signal
technology, additional bicycle and pedestrian undercrossings, enhanced
Travel Demand Management (TDM) program, and feasible intersection
improvements. This combination of mitigation measures would reduce the
SUMC Project impacts to a less-than-significant level at all of the impacted
intersections during the AM Peak: Hour. However, intersection impacts
would remain significant and unavoidable in the PM Peak Hour at tbree
intersections with mitigation.
TR-2.1 Install Traffic Adaptive Signal Technology. The SUMC Project
sponsors shall contribute to the Palo Alto Citywide Traffic
Impact Fee program, for the installation of traffic adaptive
signals. However, this fee is not structured to mitigate one
hundred percent of project related impacts, and an additional fee
could be imposed by the City on the SUMC Project sponsors to
mitigate the remaining share of the SUMC Project impacts. In
Menlo Park, the SUMC Project sponsors shall contribute their
fair share amount, which shall be tied to the amount of traffic
added to analyzed intersections by tbe SUMC Project. TIle

SUMC Project sponsors shall contribute their fair share to the
cost of construction of the Everett Avenue undercrossing of the
Caltrain tracks in Palo Alto and the Middle A venue
undercrossing in Menlo Park. In Palo Alto, there is a Citywide
Traffic Impact Fee program that the SUMC Project sponsors
shall contribute to. However, this fee is not structured to
mitigate one hundred percent of the SUMC Project related
impacts, and an additional fee may be imposed by the City to
mitigate the remaining share of the SUMC Project impacts. In

Project. The construction of the Everett Avenue and Middle
Avenue undercrossings would reduce traffic volumes on nearby
streets, such as Ravenswood Avenue and University Avenue.
TR-2.3 Enhance Stanford University Travel Demand Management (IDM)
Program. The SUMC Project sponsors shall enhance the
currently-implemented TDM program in order to achieve 35.1
percent usage of alternative transportation modes (i.e, carpool,
vanpool, bus, Caltrain, bicycle, and walk) by SUMC employees.
The initial enhancements to the SUMC TDM program shall
include the following:
• Provide Caltrain GO Passes, or an equivalent TDM
measure, to all eligible hospital employees and set target
Caltrain mode share for hospital employees equal to 15.8
percent.
• If Caltrain GO Passes would be provided to SUMC
employees, make arrangements with AC Transit to lease 75
spaces at the Ardenwood Park & Ride Lot, to serve SUMC
employees who commute from the East Bay.
• Expand bus service in support of the issuance of GO Passes.
• Expand the Marguerite shuttle bus service, and integrate it
""ith the other City of Palo Alto shuttle bus service.
• Maintain load factors less than 1.00 on the U Line, and less
than 1.25 on the Marguerite shuttle.
• Expand and improve the bicycle and pedestrian networks.
• Provide a full-time on-site TDM coordinator by 2015 for the
hospital components. The coordinator would be responsible
for organizing and disseminating TDM information primarily

to hospital employees and also to hospital patients. A central
location would be made available to provide information on
alternative travel modes. Also, the SUMC or hospitals'
website would contain information on TDM programs.
• Provide a guaranteed ride home program for all employees
who use transit and other transport alternatives like carpool
and vanpool. The guarantee ride home shall allow
employees with dependent children the ability to use
alternative modes to travel to and from work but still be able
to travel home mid-day in case of an emergency.
• Provide employees with shower facilities within the SUMC
Sites to encourage bicycling to work. The SUMC Project
sponsors shall also provide bicycle storage facilities on the
SUMC Sites that would be conveniently located near the
employee showers.
• Establish, in conjunction with the GO Pass implementation,
a "Zip Car" (or other similar car-sharing program) with Zip
Cars available at the medical complex.
• Perform annual TDM monitoring and submit the report to
the City of Palo Alto to ensure that the assumed modal split
to alternative forms of travel and away from autos is actually
achieved.
These enhancements may not immediately change the mode split
for SUMC employees, because many employees would be unable
to change long standing commute patterns overnight. However,
with the passage of a mutually agreed amount of time, it is
expected that the enhanced TDM program would gradually result
in a shift in the mode split of SUMC employees. If this proves

not to be the case, then a second round of improvements to the
TDM program shall be implemented. Examples of additional
measures could be to increase the parking permit charges while
increasing the incentives to those who carpool or do not drive.
If, by the year 2025, at least 35.1 percent of SUMC employees
are not using alternative transportation modes, then a second
round of improvements to the TDM shall be implemented.
Examples of additional measures could be to increase the parking
permit charges while increasing the incentives to those who
carpool or do not drive. Thereafter, SUMC Project sponsors
shall monitor/survey employee use of alternative modes of
transportation on an at least bi-annual basis, and shall continue to
improve its TDM program, until it is confirmed to the
satisfaction of the City that the target of 35.1 percent usage has
been met.
TR-2.4 Fund or Implement those Intersection Improvements that Have
Been Detennined to be Feasible. The SUMC Project sponsors
shall implement the following measures:
• For the intersection of El Camino Real/Page Mill Road -
Oregon Expressway, the SUMC Project sponsors shall pay a
fair share towards (1) provision of exclusive right-tum lane
for westbound Oregon Expressway, in addition to the two
through lanes, (2) increasing the cycle length to 160 seconds.
Improvements to the westbound right tum lane would
require right-of-way from the Santa Clara Valley
Transportation Authority (VTA) park-and-ride lot.
• At the intersection of Arboretum Road/Galvez Street, the
SUMC Project sponsors shall install a traffic signal.

MITIGATION MEASURES. With the provision of additional bicycle and
pedestrian undercrossings (Mitigation Measure TR-2.2), the enhanced
TDM program (Mitigation Measure TR-2.3), and contribution to the City
of Menlo Park shuttle fee (Mitigation Measure TR-7.2), there would still be
significant impacts on four Menlo Park roadways, including Marsh Road,
Willow Road, Sand Hill Road, and Alpine Road. Therefore, the traffic
impacts to Marsh Road, Sand Hill Road, Willow Road, and Alpine Road
would remain significant and unavoidable with mitigation.
MlTIGATION MEASURES. Mitigation Measure TR-4.1, involving funding
and implementation of a traffic impact study, and Mitigation Measure
TR-4.2, involving re-striping of Durand Way, would reduce the SUMC

potential additional reductions were not included in the SUMC Project's

However, it is not likely that the additional reductions in SUMC Project
TAC emissions resulting from their inlplementation would reduce the
SUMC Project health risk to the point where it would not be cumulatively
considerable in the context of Palo Alto's high TAC background levels.
Thus, SUMC Project TAC emissions would remain cumulatively significant
even after the inlplementation of all feasible TAC reduction measures.
MlTIGATION MEASURES. The mitigation measures below, wbich in addition
to the proposed Emissions Reduction Program, would further minimize the
increase in greenhouse gas emissions from this project. However, even

certain exterior surfaces and the removal, cataloging, and storage of
selective historic elements. The Documents are based on National Park
Service and National Fire Protection Agency protection guidelines and
include details on materials and methods of installation for the protective
coverings to prevent damage from nearby demolition. Proper installation,
as required in the Documents would prevent the protective covering itself
from damage the building. The removal of historic elements would ensure
their, protection of some of the more fragile elements from construction
activities and property cataloging and storage of such elements would
ensure their proper care and reinstallation. The Documents include such

CR-7. Cumulative Impacts on Paleontological Resources.
The SUMC Project, in combination with other reasonably
foreseeable probable future development where the
Pleistocene-age creek bed may occur, could have a significant
cumulative impact. Such an impact would occur if the buried
Pleistocene-age creek bed is exposed in lengths greater than
approximately 100 feet (or a sufficient length to support
detailed hydrological study) and if such deposits contain
substantially intact skeletons of extinct species. These
conditions would represent a major find for regional
paleontology. In the case that significant paleontological
finds-such as stretches of buried Pleistocene-age creek bed
greater than 100 feet in length and containing intact skeletons
of extinct species-are made on the SUMC Site, then the

found, no further mitigation is required. If a bat roost is found,
the SUMC Project sponsors shall implement the following
measures to avoid impacts on roosting bats.
BR-I.2 Avoid Roosting Areas. If non-breeding bats are found in a tree or
structure to be removed, the individuals shall be safely evicted,
under the direction of a qualified bat biologist, by opening the
roosting area to allow airflow through the cavity. Demolition
should then follow at least one night after initial disturbance for
airflow. This action should allow bats to leave during darkness,
thus increasing their chance of finding new roosts with a
minimum of potential predation during daylight.
If active maternity roosts are found in structures that will be
removed as part of project construction, demolition of that
structure shall commence before maternity colonies form
(generally before March 1) or after young are flying (generally
by July 31).

Additionally, if more than 5 days elapses between the initial nest
search and the tree removal, it is possible for new birds to move
into the construction area and begin building a nest. If there is
such a delay, another nest survey shall be conducted. If any
active Cooper's hawk nests are detected, the SUMC Project

PH-3. Impacts on Jobs to Employed Residents Ratio. The

jobs to employed residents ratio because it would exceed the
existing Comprehensive Plan and zoning allowances for the

relating to additional commute traffic, including the significant
and unavoidable impacts on air quality and climate change, as

Mitigation Measures
MITIGATION MEASURE. Implementation of Mitigation Measure PH-3.1
would reduce the impact on the City's jobs to employed residents ratio;
however, such implementation would not fully avoid the SUMC Project's
impact on the jobs to employed residents ratio because (1) the measures
would not guarantee provision of housing units to cover the demand from
the 1,052 households (or 8 percent thereof), and (2) due to the various
factors that people consider in choosing where to live, it cannot be
ascertained that the 1,810 workers would choose to live in Palo Alto. Due
to the high concentration of jobs in Palo Alto, it is possible that a strong
affordable housing program would result in reduced traffic congestion,
vehicle miles traveled, and greenhouse gas emissions.
Implementation of Mitigation Measure PH-3.1 is not directly required in
order to mitigate a significant environmental impact, but rather should be
considered as possible additional mitigation for Impacts AQ-2, AQ-7,
CC-l, and CC-2, as discussed in Section 3.5, Air Quality, and Section 3.6,
Climate Change, of this EIR. However, it should be stressed that these
measures are presented here only in conceptual tenDs, and the City may
find that some or all of them are not feasible for various legal, practical, or
other reasons. As such, Mitigation Measure PH-3.1 is presented for
informational purposes, and to ensure that all possible options for
mitigation of these inlpacts are adequately considered.
PH-3.I Reduce the Impacts on the Jobs to Employed Residents Ratio. In
order to reduce tlle SUMC Project's impacts on the City'S jobs to
employed residents ratio, one or more of the following measures
shall be implemented by both the City and the SUMC Project
