RESOLUTION OF THE COUNCIL OF THE CITY OF PALO ALTO
CERTIFYING THE ADEQUACY OF THE FINAL
ENVIRONMENTAL IMPACT REPORT FOR THE EMERGENCY
WATER SUPPLY AND STORAGE PROJECT PURSUANT TO THE
CALIFORNIA ENVIRONMENTAL QUALITY ACT AND
ADOPTING THE MITIGATION MONITORING AND REPORTING
PROGRAM AND THE STATEMENT OF OVERRIDING
CONSIDERATIONS
The Council of the City of Palo Alto does RESOLVE as follows:
SECTION 1. Introduction and Certification.
(a) The following findings are hereby adopted by the City Council of the City of
Palo Alto ("City Council") to comply with the requirements of the California Environmental
Quality Act ("CEQA"; Pub. Resources Code, §§ 21000 et seq.), and Sections 15091, 15092,
15093, and 15162 of the CEQA Guidelines (14 Cal. Code Regs., § 15000 et seq.). These
[ findings are made relative to the conclusions of the City of Palo Alto Emergency Water Supply
and Storage Project Final Environmental Impact Report (State Clearinghouse No. 2066022038)
(the "Final EIR"), which includes the Draft Environmental Impact Report ("Draft EIR"), Public
Comments, and Responses to Comments. The Final EIR addresses the environmental impacts of
the implementation of the proposed Project and is incorporated herein by reference.
(b) Mitigation measures associated with the potentially significant impacts of the
Project will be implemented through the Mitigation Monitoring Program for the Project, which is
the responsibility of the City, thereby ensuring that the City of Palo Alto Emergency Water
Supply and Storage Project (the "Project") will have no significant adverse environmental
impacts, except as noted herein.
(c) The City of Palo Alto is the Lead Agency pursuant to Public Resources Code
section 21067 as it has the principal responsibility to carry out and approve the Project, which
may have a significant impact upon the environment.
(d) Based upon review and consideration of the information contained therein,
the City Council hereby certifies that the Final EIR was completed in compliance with CEQA,
and reflects the City of Palo Alto's independent judgment and analysis. The City Council has
considered evidence and arguments presented during consideration of the Project and the Final
EIR. In determining whether the Project may have a significant impact on the environment, and
in adopting the findings set forth below, the City Council certifies that it has complied with
Public Resources Code sections 21081, 21081.5, and 21082.2.

070403 syn 6050099
( e) The City Council hereby finds, determines, and declares that no significant
new information has been added to the Final EIR so as to warrant recirculation of all or a portion
of the Draft EIR.
SECTION 2. Project Information.
The following Project information is supplied to provide context for the discussion
and findings that follow, but is intended as a summary and not a replacement for the information
contained in the Draft EIR, Final EIR, or Project approval resolution.
The Project, if implemented, would be undertaken by the City of Palo Alto and
would consist of various capital improvements intended to correct an existing deficiency in the
City's emergency water supply. As the City of Palo Alto currently relies on the San Francisco
Public Utilities Commission Hetch Hetchy system for its water supply, the purpose of the Project
is to provide enough water to meet normal and emergency demands of the City in the event of a
temporary shutdown of the Hetch Hetchy aqueducts. Specifically, the Project consists of
upgrades to five existing City wells, construction of up to three new wells (six alternative well
locations are fully analyzed in the Final EIR), construction of one new water storage reservoir
with an associated pump station (four alternative well locations are fully analyzed in the Final
EIR), and upgrade of the existing Mayfield Pump Station. The Project would provide 11,000
gpm of reliable well capacity, and 2.5 million gallons of water storage for emergency use in
'underserved areas of the City.
SECTION 3. Record of Proceedings.
(a) For purposes of CEQA, CEQA Guidelines section 15091(e), and these
findings, the Record of Proceedings for the Project consists of the following documents, at a

Project.
(e) The City Council hereby finds, determines and declares that the above-
referenced documents, materials, and evidence constitute substantial evidence (as that term is
defined by section 15384 of the CEQA Guidelines) to support each of the findings contained
herein.
SECTION 4. Mitigation Monitoring Program.
(a) CEQA requires the lead agency approving a Project to adopt a Mitigation
Monitoring Program (MMP) for the changes made to the Project that it has adopted in order to
mitigate or avoid significant effects on the environment. An MMP has been prepared and is
recommended for adoption by the City Council concurrently with the adoption of these findings
to ensure compliance with mitigation measures during Project implementation. As required by
Public Resources Code section 21081.6, the MMP designates responsibility and anticipated
timing for the implementation of the mitigation measures recommended in the Final EIR. The
MMP will remain available for public review during the compliance period.
(b) The City Council hereby adopts the MMP for the Project attached hereto and
incorporated by reference, and finds, determines, and declares that adoption of the MMP will
ensure enforcement and continued imposition of the mitigation measures recommended in the
Final EIR, and set forth in the MMP, in order to mitigate or avoid significant impacts on the
environment.
SECTION 5. Impacts Determined to be Less Than Significant.
(a) Scoping
A Notice of Preparation for the Project was prepared and distributed on
February 6, 2006 to all responsible and trustee agencies and interested parties. The notice
solicited views of interested persons and agencies as to the scope and content of the
3
070403 syn 6050098
environmental information to be studied in the Draft ElR. The City of Palo Alto also held a
public scoping meeting to receive public comments and suggestions on the Project on March 8,
2006. Through the scoping process, which included both agency consultation pursuant to Public
Resources Code section 21080.4(a) and CEQA Guidelines section 15082, and early public
consultation pursuant to CEQA Guidelines section 15083, the City identified the range of
actions, alternatives, mitigation measures, and significant effects to be analyzed in depth in the
Draft EIR, and eliminated from detailed study issues found not to be important.
(b) Draft and Final EIR Identified Impacts
(1) The Draft EIR and Final EIR concludes that the Project would result
in no impact or a less-than-significant impact in the areas listed below because: (1) mitigating
features are incorporated into the Project; (2) existing standard regulations that apply to the
Project will mitigate the impact; (3) the level of impact will not exceed the identified thresholds
of significance, or (4) the impacts of the Project will be beneficial.
070403 syn 6050098
i. Agricultural resources (see DEIR, p. 3.2-11);
ii. Intensity of overall existing or planned land use patterns (see
DEIR, p. 3.2-12);
iii. Terrain modification (see DEIR, p. 3.3-29);
iv. Shadow of public open space (see DEIR, p. 3.3-29);
v. Division of an established community (Impact 3.2-1);
vi. Conflicts with Land Use and Natural Resource Plans (Impact

xiv. Emergency response plan impacts (Impact 3.11-5);
xv. Wildland fire risk (Impact 3.11-6);
xvi. Cumulative long-term impacts to land use (Impact 4.2);
xvii. Cumulative long-term impacts to water resources (Impact
4.4);
xviii. Cumulative long-term impacts to groundwater resources
(Impact 4.5).

(2) The City Council hereby finds, detennines, and declares that it has
reviewed the Draft EIR and the Final EIR with respect to the areas of potential impact set forth
above, and finds that the conclusions of the Draft EIR and Final EIR are supported by substantial
evidence in the record, including the detailed descriptions of potential impacts contained in the
Draft EIR, and the additional infonnation and analysis contained in the Final EIR. The City
Council further finds that no evidence has been introduced that would tend to call into question
any of the conclusions of the Draft EIR or the Final EIR with respect to such impacts. The City
Council has independently exercised its judgment to conclude that each of the above impacts is
less-than-significant or no impact, and therefore requires no mitigation except as embodied in the
Project.
SECTION 6. Significant Impacts that Can be Avoided or Mitigated to a Less-Than-
Significant Level.
The Draft EIR and the Final EIR concluded that the Project would result in
potentially significant environmental impacts in the areas listed below. Through the imposition
of the identified mitigation measures, the identified potentially significant environmental impacts
will be reduced to less-than-significant impacts.
(a) Land Use, Agricultural Resources, and Recreation
(1) Impact 3.2-3: Recreation Impacts. As set forth on pages 3.2-15 to
J 3 .2-17 of the Draft EIR, construction of some proposed Project facilities could temporarily
disrupt access to or enjoyment of existing recreational facilities, and could temporarily result in
overcrowding of other recreational facilities. The Draft EIR concludes that this impact is
potentially significant.
i. Mitigation Measures 3.2-3a, 3.2-3b (Draft EIR, p. 3.2-17).
These mitigation measures would, among other things, require the City to provide notice to all
surrounding neighbors and other interested parties regarding the park closure and access
disruption schedule. The public notification program would include po stings on the City's
website. During Project construction, the City shall work with the Parks Services division to
reschedule park usage accordingly.
(2) The City Council hereby finds, detennines, and declares that,
pursuant to CEQA Guidelines section 15091(a)(1), changes or alterations have been required in,
or incorporated into, the Project which avoid or substantially lessen the significant environmental
effect identified in the Final EIR. Specifically, the measures required by Mitigation Measures
3.2-3a and 3.2-3b substantially reduce the disruption of access to recreational facilities in the
City. With this mitigation, the potential impacts to the City's recreational facilities are therefore
found to be less-than-significant.
(b) Visual Quality.
(1) Impact 3.3-1: Short-tenn visual effects experienced from nearby
areas during Project construction. As set forth on pages 3.3-29 to 3.3-32 of the Draft EIR,
5
070403 syn 6050098
construction activities associated with the Project could result in short-tenn, potentially
significant visual quality impacts.
i. Mitigation Measures 3.3-1a. 3.3-1b. 3.3-1c. 3.6-2a. 3.6-2b.
3.6-2c. 3.6-2d (Draft EIR, pp. 3.3-32 -3.3-33.). These mitigation measures require attractive
and easy to understand graphics, screening and maintenance, restoration of Project construction
and staging areas, and implementation of a tree protection and preservation plan.
(2) Impact 3.3-2: Alteration of the site's appearance and long-tenn visual
effects. As set forth on pages 3.3-33 to 3.3-35 of the Draft EIR, construction of the Project may
alter the site's appearance and cause potentially significant long-tenn visual effects.
i. Mitigation Measures 3.3-2a, 3.3-2b, 3.6-2a, 3.6-2b, 3.6-2c.
3.6-2d (Draft EIR. p. 3.3-35). These mitigation measures require use of design elements to
enhance the aesthetic appearance of proposed facilities, and use of colors selected based on site-
specific conditions. Implementation of detailed landscaping plans and a tree protection and
preservation plan is also required.
(3) Impact 3.3-3: New sources of light and glare. As set forth on pages
3.3-35 and 3.3-36 of the Draft EIR, the Project may result in potentially significant temporary
light and glare impacts associated with well drilling activities, and potentially significant long-
tenn light and glare impacts associated with security lighting at the new facilities.
i. Mitigation Measures 3.3-3a, 3.3-3b, 3.3-1c (Draft EIR. p. 3.3-
36). To the extent possible, these mitigation measures require construction lighting to be directed
downward and oriented so that no light source is directly visible from neighboring residential
areas. Additionally, highly reflective building material will not be used, and full cutoff, low-
intensity light fixtures will be required to be installed. Restoration of any removed landscaping
is also required.
(4) The City Council hereby finds, detennines, and declares that,
pursuant to CEQA Guidelines section 15091(a)(1), changes or alterations have been required in,
or incorporated into, the Project which avoid or substantially lessen the significant environmental
effects identified in the Final EIR. Specifically, the measures required by Mitigation Measures
3.3-1a, 3.3-1b, 3.3-1c, 3.6-2a, 3.6-2b, 3.6-2c, 3.6-2d, 3.3-2a, 3.3-2d, 3.3-3a, and 3.3-3b
substantially reduce the Project's temporary visual quality impacts. With this mitigation, the
visual quality impacts are therefore found to be less-than-significant.
(c) Geology, Soils and Seismicity
(1) Impact 3.4-1: Ground shaking capable of causing localized collapse
or damage of engineered fills, structural damage, pipeline rupture, or equipment topple. As set
forth on pages 3.4-12 to 3.4-13 of the Draft EIR, earthquake ground shaking could damage
structures, including buildings, roads, bridges, water conveyance pumping equipment,
engineered slopes, buried pipelines and rail lines. This impact is identified as potentially
significant.
6
070403 syn 6050098
i. Mitigation Measure 3.4-1 (Draft EIR, p. 3.4-13). Mitigation
Measure 3.4-1 requires a design-level geotechnical investigation, and implementation of site-
specific criteria using the California and Uniform Building Codes and structural engineers to
mitigate potential risks.
(2) Impact 3.4-2: Liquefaction Impacts. As set forth on page 3,4-14 of
the Draft EIR, certain Project location could be subjected to liquefaction ground failures in the
event of an earthquake. This impact is identified as potentially significant.
i. Mitigation Measure 3.4-2 (Draft EIR, pp. 3.4-14 -3.4-15).
Prior to approval of construction plans, a design level geotechnical investigation shall be
completed, and site-specific design criteria designed to mitigate potential risks shall be
developed and implemented during construction.
(3) Impact 3.4-3: Expansive soils impacts. As set forth on page 3.4-15
of the Draft EIR, several existing and proposed Project sites are underlain by expansive soils and
could be subjected to damage to foundations, pavement, roadways, and facilities over time.
i. Mitigation Measures 3.4-1, 3.4-2 (Draft EIR, p. 3.4-15).
These mitigation measures require a design level geotechnical investigation to be completed, and
site-specific design criteria designed to mitigate potential risks to be developed and
implemented.
(4) The City Council hereby finds, determines, and declares that,
pursuant to CEQA Guidelines section 15091(a)(1), changes or alterations have been required in,
or incorporated into, the Project which avoid or substantially lessen the significant environmental
effects identified in the Final EIR. Specifically, the measures required by Mitigation Measures
3.4-1 and 3.4-2 substantially reduce the Project's ground-shaking, liquefaction, and soils
impacts. With this mitigation, the Project's above-identified ground-shaking, liquefaction, and
soils impacts are therefore found to be less-than-significant.
(d) Hydrology and Water Quality
(1) Impact 3.5·1: Project construction could result in increased erosion
and sedimentation and could increase turbidity and decrease water quality. As set forth on pages
3.5-13 to 3.5-16 of the Draft EIR, construction of the Project could result in potentially
significant impacts related to erosion, sedimentation, and increased turbidity.
i. Mitigation Measures 3.5-1a, 3.5·1b (Draft EIR, pp. 3.5-16 -
3.5-17.) These mitigation measures would require compliance with the NPDES Construction
Activity Storm Water Permit, and implementation of a Storm Water Pollution Prevention Plan
prepared for the Project prior to construction. Additionally, subject to agreement and permit
issuance from appropriate regulatory agencies, stream crossing using open-trench construction
would be required to be limited to the dry season, or microtunneling techniques would be
required to be implemented.
7
070403syn 6050098
(2) Impact 3.5-2: Construction of propose facilities would result in a
minor increase in local storm runoff volumes. As set forth on pages 3.5-17 and 3.5-18 of the
Draft EIR, the Project would result in the construction of three new wells and a below grade
reservoir with attendant facilities. These facilities would result in an incremental increase of .7
acres of impervious surface, which is a potentially significant impact.
i. Mitigation Measure 3.5-2 (Draft EIR, p. 3.5-18). This
mitigation measure requires compliance with applicable NPDES permits, and conveyance of
stormwater runoff to appropriate local drainage systems.
(3) Impact 3.5-3: If necessary, dewatering during construction activities
could result in the discharge of turbid waters into the storm drain systems or nearby creeks. As
set forth on page 3.5-18 of the Draft EIR, dewatering activities, if necessary, may result in
potentially significant impacts associated with degradation of water quality.
i. Mitigation Measure 3.5-1a (Draft EIR, p. 3.5-19). This
mitigation measure requires compliance with the NPDES Construction Activity Storm Water
Permit, and implementation of a Storm Water Pollution Prevention Plan prior to construction.
(4) Impact 3.5-4: Increased groundwater recovery to meet emergency or
drought demands would have the potential to impact aquifer recovery rates and/or result in
'groundwater levels below historical low elevations. As set forth on pages 3.5-19 and 3.5-20 of
the Draft EIR, extraction of groundwater in emergency or drought conditions may impact aquifer
recovery rates, and/or result in groundwater levels below historical low elevations. Without
mitigation, this impact is identified as potentially significant.
i. Mitigation Measures 3.5-4a, 3.5-4b (Draft EIR, p. 3.5-20).
These mitigation measures would require an aquifer test to be conducted to verify the basin's
response to pumping, and will limit the emergency demand pumpage to 1,500 acre feet in one
year.
(5) Impact 3.5-6: Placement of new wells would alter localized
groundwater gradients during emergency operations, and could result in direct effects to the
efficiency of existing wells due to well interference. As set forth on page 3.5-21 of the Draft
EIR, operation of new wells may potentially significantly impact existing production facilities.
i. Mitigation Measure 3.5-6 (Draft EIR, p. 3.5-21). This
mitigation measure would require that new well facilities be located more than 500 feet from
existing municipal production wells.
(6) Impact 3.5-7: Construction and operation of potable supply wells
would have the potential to affect the quality of potable water and public health. As set forth on
pages 3.5-21 to 3.5-22 of the Draft EIR, potable water quality may be affected by the proposed
Project. Without mitigation, this impact would be potentially significant.
8
070403 syn 6050098
i. Mitigation Measure 3.5-7 (Draft EIR, p. 3.5-22). This
mitigation measure requires all new wells to be approved, designed, and operated in compliance
with all applicable California Department of Health Services and Santa Clara Valley Water
District requirements.
(7) The City Council hereby finds, determines, and declares that,
pursuant to CEQA Guidelines section 15091(a)(1), changes or alterations have been required in,
or incorporated into, the Project which avoid or substantially lessen the significant environmental
effect identified in the Final EIR. Specifically, the measures required by Mitigation Measures
3.5-1a, 3.5-1b, 3.5-2, 3.5-4a, 3.5-4b, 3.5-6, and 3.5-7 substantially reduce the Project's
hydrology and water quality related impacts. With this mitigation, the Project's above-identified
hydrology and water quality impacts are therefore found to be less-than-significant.
(e) Biological Resources
(1) Impact 3.6-1: Accidental discharge of sediment or toxic materials to
jurisdictional waters and aquatic habitat. As set forth on pages 3.6-22 to 3.6-26 of the Draft EIR,
there is a possibility that erosion resulting from Project construction activities or an accidental
discharge of sediment or toxic materials could directly impact jurisdictional waters and aquatic
habitat where construction is proposed directly adjacent to npanan areas. This impact is
identified as potentially significant.
i. Mitigation Measure 3.6-1 (Draft EIR, p. 3.6-26). This
mitigation measure requires the City to implement standard best management practices, comply
with the City's stormwater discharge ordinance, and the applicable NPDES permits.
(2) Impact 3.6-2: Implementation of the proposed Project would result in
the removal of, pruning of, and potential damage to trees and other vegetation. As set forth on
pages 3.6-26 to 3.6-31 of the DEIR, Project activities, including construction of pipeline
connections that could extend from a Project site and construction staging areas, could result in
the removal of, pruning of, and potential damage to trees and other vegetation in the Project area.
Without mitigation, this impact is potentially significant.
i. Mitigation Measures 3.6-2a, 3.6-2b, 3.6-2c, 3.6-2d (Draft EIR,
pp. 3.6-31 -3.6-32.) These mitigation measures require preparation and implementation of a
tree protection and preservation plan, protection of trees in accordance with the tree technical
manual, and replacement of any removed trees or other protected vegetation according to the
City's requirements.
(3) Impact 3.6-3: Activities associated with the construction of the
proposed Project could result in adverse impacts on special-status bird species. As set forth on
pages 3.6-32 to 3.6-36 of the Draft EIR, construction activities associated with the proposed
Project components that are implemented during the breeding season, including removal of trees
and other nesting habitat, have the potential to result in direct mortality of special-status birds.
This impact is identified as potentially significant.
9
070403 syn 6050098
i. Mitigation Measure 3.6-3 (Draft EIR, pp. 3.6-36 -3.6-37).
Mitigation Measure 3.6-3 requires the City to avoid disturbance of breeding special status birds.
(4) hnpact 3.6-4: Removal of trees and other proposed construction
activities during the breeding season could result in impacts to special-status bats. As set forth
on pages 3.6-37 to 3.6-41 of the Draft EIR, construction activities associated with the proposed
Project could result in potentially significant impacts to special-status bats.
i. Mitigation Measure 3.6-4 (Draft EIR, pp. 3.6-41 -3.6-42).
This mitigation measure requires the City to avoid disturbance to maternity roosts of special-
status bats during the breeding season.
(5) The City Council hereby finds, determines, and declares that,
pursuant to CEQA Guidelines section 15091(a)(l), changes or alterations have been required in,
or incorporated into, the Project which avoid or substantially lessen the significant environmental
effects identified in the Final EIR. Specifically, the measures required by Mitigation Measures
3.6-1, 3.6-2a, 3.6-2b, 3.6-2c, 3.6-2d, 3.6-3, and 3.6-4 substantially reduce the Project's biological
resources related impacts. With this mitigation, the Project's above-identified biological
resources impacts are therefore found to be less-than-significant.
(f) Cultural Resources
(1) Impact 3.7-1: Potential adverse effects to historical resources or
unique archaeological resources, including those previously unidentified. As set forth on pages
3.7 -10 to 3.7-16, previously unknown and buried prehistoric or historic resources may be present
almost anywhere in the construction zones identified for the Project. As the Project would
involve excavation, the Project could potentially result in the degradation or destruction of
unrecorded cultural resources. This impact is identified as potentially significant.
i. Mitigation Measures 3.7-1a, 3.7-1b (Draft EIR, pp. 3.7-16 -
3.7-19). These mitigation measures require the City to take certain actions upon the discovery
of any prehistoric or historic resources during ground disturbing activities. Additionally, in areas
determined to have high potential for unknown or poorly documented archaeological resources, a
qualified consultant shall be required to monitor ground-disturbing or vegetation removal
activity.
(2) Impact 3.7-2: Potential adverse effect to the Hale Pump House. As
set forth on page 3.7-19 of the DEIR, if the Project requires alteration of the Hale Pump House,
this action would be considered a significant environmental impact.
i. Mitigation Measure 3.7-2 (Draft EIR, p. 3.7-19). This
mitigation measure would require review by the Palo Alto Historic Resources Board, and
implementation of any board recommendations. Additionally, this mitigation measure requires
rehabilitation or reconstruction of the Hale Pump House in accordance with CEQA Guidelines
section 15064.5(b)(3).
10
070403syn 6050098
(3) Impact 3.7-3: Potential adverse effects on paleontological resources.
As·set forth on page 3.7-19 of the Draft EIR, excavation activities associated with construction
of the Project may have a deleterious effect on paleontological resources. This impact, without
mitigation, is identified as potentially significant.
1. Mitigation Measure 3.7-3 (Draft EIR, p. 3.7-3). This
mitigation measure requires notification of a qualified paleontologist of unanticipated
discoveries, and evaluation and assessment of the find pursuant to CEQA Guidelines section
15064.5.
(4) The City Council hereby finds, determines, and declares that,
pursuant to CEQA Guidelines section 15091(a)(1), changes or alterations have been required in,
or incorporated into, the Project which avoid or substantially lessen the significant environmental
effects identified in the Final EIR. Specifically, the measures required by Mitigation Measures
3.7-1a, 3.7-lb, 3.7-2, and 3.7-3 substantially reduce the Project's impacts on cultural resources.
With this mitigation, the Project's above-identified cultural resources impacts are therefore found
to be less-than-significant.
(g) Traffic and Circulation
(1) Impact 3.8-1: Short-term traffic and transportation conditions
dmpacts. As set forth on pages 3.8-11 to 3.8-17 of the Draft EIR, the Project would result in
temporary construction-generated traffic, including movement of construction trucks and
lessening of roadway capacities. Without mitigation, these short term impacts are identified as
potentially significant.
i. Mitigation Measures 3.8-la, 3.8-lb, 3.8-lc, 3.8-ld, 3.8-le,
3.8-1 f, 3.8-lg, 3.8-lh (Draft EIR, pp. 3.8-17 -3.8-18). These mitigation measures would require
the City to obtain all necessary road encroachment permits, prepare and implement a traffic
control and traffic management plan, implement special construction techniques to minimize
impacts to traffic flow, develop circulation and detour plans, coordinate with CalTrans or other
appropriate to minimize cumulative impacts, coordinate bus stop relocations, and develop
circulation and detour plans to minimize the impact to bicycle transportation.
(2) Impact 3.8-2: Short-term emergency access impacts. As set forth on
pages 3.8-18 and 3.8-19 of the Draft EIR, the Project would have temporary, potentially
significant effects on traffic flow that could result in delays for emergency vehicle access in the
vicinity of construction sites.
i. Mitigation Measure 3.8-1 b (Draft EIR, p. 3.8-19). This
mitigation measure requires the City to prepare and implement a traffic control and traffic
management plan.
(3) Impact 3.8-3: Short-term transportation service impacts. As set forth
on page 3.8-19 of the Draft EIR, the Project could temporarily disrupt access to bus stops and
could conflict with bicycle traffic.
11
070403 syn 6050098
i. Mitigation Measure 3.8-1g (Draft EIR, p. 3.8-19). This
mitigation measure requires the City to consult with VTA, Sam Trans, and any other appropriate
transit district to coordinate bus stop relocations and to reduce potential interruption of transit
service.
(4) Impact 3.8-4: Short-term demand for parking spaces. As set forth on
pages 3.8-19 to 3.8-22 of the Draft EIR, during construction activities, the Project would create
temporary parking demand for construction workers and construction vehicles, and would
temporarily reduce the available parking supply at propose well and storage reservoir locations.
This impact is identified as potentially significant.
i. Mitigation Measures 3.8-4a, 3.8-4b, 3.8-4c, 3.8-4d, 3.8-4e,
3.8-4f, 3.8-1e (Draft EIR, p. 3.8-22, as revised in the Final EIR at p. 5-12). These mitigation
measures require that construction parking be provided in the vicinity of the work zone.
Additionally construction must be scheduled to avoid peak shopping seasons, in lieu fees are
required if spaces in the downtown lots are lost, and the parking layout at the California lot shall
be redesigned.
(5) Impact 3.8-5: Traffic Safety Impacts. As set forth on pages 3.8-22 to
3.8-23 of the Draft EIR, construction zones in or near the public right-of-way could increase the
'potential for accidents. This impact is identified as potentially significant.
i. Mitigation Measures 3.8-1b, 3.8-1c, 3.8-1d, 3.8-1e, 3.8-1f,
3.8-1g, 3.8-1h (Draft EIR, p. 3.8-23). These mitigation measures would require the City to
obtain all necessary road encroachment permits, prepare and implement a traffic control and
traffic management plan, implement special construction techniques to minimize impacts to
traffic flow, develop circulation and detour plans, coordinate with CalTrans or other appropriate
to minimize cumulative impacts, coordinate bus stop relocations, and develop circulation and
detour plans to minimize the impact to bicycle transportation.
(6) Impact 3.8-6: Wear-and-tear on the designated haul routes and in
public parking lots used by construction vehicles to access the Project work sites. As set forth on
page 3.8-23 of the Draft EIR, the use of large trucks to transport equipment and material to and
from the Project work sites could affect road conditions on the designated haul routes, and
conditions of parking lots by increasing the rate of road wear. This impact is identified as
potentially significant without mitigation.
i. Mitigation Measure 3.8-6 (Draft EIR, pp. 3.8-23 -3.8-24).
This mitigation measure requires implementation of a road/parking lot rehabilitation program by
the contractor pursuant to an agreement with the City.
(7) The City Council hereby finds, determines, and declares that, with the
exception of the potential parking impacts at the California Avenue parking lot site, pursuant to
CEQA Guidelines section 15091 (a)(1), changes or alterations have been required in, or
incorporated into, the Project which avoid or substantially lessen the significant environmental
12
070403 syn 6050098
effects identified in the Final EIR. Specifically, the measures required by Mitigation Measures
3.8·-la, 3.8-1b, 3.8-1c, 3.8-1d, 3.8-1e, 3.8-lf. 3.8-1g, 3.8-1h, 3.8-4a, 3.8-4b, 3.8-4c, 3.8-4d, 3.8-
4e, 3.8-4f, and 3.8-6 substantially reduce the Project's impacts on traffic and circulation. With
this mitigation, and with the exception of the potential parking impacts at the California Avenue
parking lot site, the Project's above-identified traffic and circulation impacts are therefore found
to be less-than-significant.
(h) Air Quality
(1) Impact 3.9-1: Short-term emissions of criteria pollutants, including
suspended and inhalable particulate matter and equipment exhaust emissions. As set forth on
pages 3.9-7 to 3.9-10 of the Draft: EIR, construction of the proposed Project would require
ground clearing and excavation activities and could generate substantial amounts of fugitive dust
(including PMl 0). This impact is identified as potentially significant.
i. Mitigation Measures 3.9-1a, 3.9-1b (Draft: EIR, pp. 3.9-10 -
3.9-11). These mitigation measures require implementation of the Bay Area Air Quality
Management District's Basic Control Measures, and additional measures where applicable.
Additionally, construction equipment is required to be properly tuned and maintained, diesel
trucks may not idle for greater than five minutes, and construction workers shall be encouraged
to carpool. ,
(2) The City Council hereby finds, determines, and declares that,
pursuant to CEQA Guidelines section 15091(a)(l), changes pr alterations have been required in,
or incorporated into, the Project which avoid or substantially lessen the significant environmental
effects identified in the Final EIR. Specifically, the measures required by Mitigation Measures
3.9-1a and 3.9-1b substantially reduce the Project's short-term air quality impacts. With this
mitigation, the Project's above-identified air quality impacts are therefore found to be less-than-
significant.
(i) Noise and Vibration
(1) Impact 3.10-1: Construction of proposed facilities (including well
drilling) would generate temporary noise levels above existing ambient conditions, resulting in
City Municipal Code violations. As set forth on pages 3.10-11 to 3.10-13 of the Draft: EIR, and
as revised on page 5-17 of the Final EIR, construction activities would generate significant
amounts of noise at the Project sites. These impacts are identified as potentially significant.
i. Mitigation Measures 3.10-1 a, 3.10-1 b, 3.10-1 c, 3.10-1 d, 3.10-
Ie (Draft: EIR, p. 3.10-14). These mitigation measures would require, among other things, that
certain Project components be sited at least 100 feet from sensitive receptors, that an engineered
sound wall or noise blanket be installed and maintained during construction, and that residents
and sensitive receptors within 1,000 feet of construction sites be notified prior to construction.
(2) Impact 3.10-3: Operational noise impacts. As set forth on page 3.10-
15 of the Draft: EIR, operational noise associated with the proposed facilities would include
13
010403 syn 6050098
infrequent use of pumps and emergency generators. This impact is identified as potentially
significant.
i. Mitigation Measures 3. 10-3 a, 3.1O-3b, 3.1O-3c. These
mitigation measures would require pump house and well enclosures to be designed such that
operational noise would meet City performance standards. Additionally, emergency generators
shall be fully enclosed in sound-attenuated housing.
(3) The City Council hereby finds, determines, and declares that, with the
exception of noise impacts related to 24-hour well drilling activities, pursuant to CEQA
Guidelines section 15091(a)(l), changes or alterations have been required in, or incorporated
into, the Project which avoid or substantially lessen the significant environmental effect~·
identified in the Final EIR. Specifically, the measures required by Mitigation Measures 3.l0-1a,
3.1O-1b, 3.l0-1c, 3.10-ld, 3.1O-1e, 3. 10-3 a, 3.1O-3b, and 3.l0-3c substantially reduce the
Project's construction and operational noise impacts. With this mitigation, and with the
exception of noise impacts related to 24-hour well drilling activities, the Project's above-
identified noise impacts are therefore found to be less-than-significant.
G) Hazards and Hazardous Materials
(1) Impact 3.11-1: Exposure of the public or the environment to
lhazardous materials or waste through inadvertent excavation of contaminated soil or
groundwater. As set forth on pages 3.11-8 to 3.11-11 of the Draft EIR, Project construction
would include grading, excavation, trenching, and other activities that would disturb soil and
have the potential to disturb groundwater. If such disturbance occurred on properties
contaminated by hazardous materials, construction workers, the public, and/or the environment
may be exposed to a localized release of compounds considered hazardous to human health or
the environment. This is identified as a potentially significant impact.
i. Mitigation Measures 3.1 I-la, 3.11-1b, 3.11-lc (Draft EIR, pp.
3.11-11 -3.11-12). Among other things, these mitigation measures would require pre-
construction soil and groundwater testing to determine whether the subsurface was impacted by
offsite contaminations. If contaminate soil is encountered, these measures require delineation,
removal, and disposal in accordance with City and state requirements.
(2) Impact 3.11-2: Use of hazardous materials during construction. As
set forth on page 3.11-12 of the Draft EIR, construction activities would require the use of
certain hazardous materials. The potential inadvertent release of hazardous materials is
considered a potentially significant environmental impact.
i. Mitigation Measures 3.11-2a. 3.l1-2b, 3.11-2c, 3.11-2d
(DEIR, pp. 3.11-12 -3.11-13.) These mitigation measures require the contractor to use best
management practices to minimize potential effects on groundwater and soils, and to ensure that,
in the event of a release, containment and cleanup occurs in accordance with all applicable
regulatory requirements. Additionally, these mitigation measures require disposal of spent oil
14
070403syn 6050098
and other solvents in accordance with all applicable regulatory requirements, and preparation of
a construction health and safety plan ..
(3) Impact 3.11-3: Use of hazardous materials, substances, or waste
within one-quarter mile of an existing schoo 1. As set forth on page 3.11-13 of the Draft EIR,
there are schools located within one-quarter mile of several of the proposed Project sites, and
grading and excavation activities have the potential to disturb contaminated soils or groundwater.
The Draft EIR identifies this impact as potentially significant.
i. Mitigation Measures 3.11-la, 3.11-lb (Draft EIR, p. 3.11-13).
Among other things, these mitigation measures would require pre-construction soil and
groundwater testing to determine whether the subsurface was impacted by offsite
contaminations. If contaminate soil is encountered, these measures require delineation, removal,
and disposal in accordance with City and state requirements.
(4) Impact 3.11-4: Operational use of hazardous materials. As set forth
on pages 3.11-13 to 3.11-15 of the Draft EIR, each of the proposed new and renovated well sites
would be designed to temporarily store and utilize two chemical solutions. These chemicals
would be used to chloraminate the groundwater extracted from the wells. These chemicals could
spill or leak from their containers. This impact is identified as potentially significant.
i. Mitigation Measure 3.11-4 (Draft EIR, p. 3.11-5). This
mitigation measure requires the Project to be designed in accordance with the latest adopted
versions of the Building and Fire Codes.
(5) The City Council hereby finds, determines, and declares that,
pursuant to CEQA Guidelines section 15091(a)(1), changes or alterations have been required in,
or incorporated into, the Project which avoid or substantially lessen the significant environmental
effects identified in the Final EIR. Specifically, the measures required by Mitigation Measures
3.11-la, 3.11-1 b, 3.11-lc, 3.11-2a, 3.11-2b, 3.11-2c, 3.11-2d, and 3.11-4 substantially reduce the
Project's hazards and hazardous materials impacts. With this mitigation, the Project's above-
identified hazards and hazardous materials impacts are therefore found to be less-than-
significant.
(k) Public Services and Utilities
(1) Impact 3.12-1: Temporary, planned, or accidental disruption to utility
services. As set forth on pages 3.12-5 of the Draft EIR, construction activities associated with
the Project could potentially result in utility conflicts, due to their potential location within
existing roadways. This impact is identified as potentially significant.
i. Mitigation Measure 3.12-1 (Draft EIR, pp. 3.12-6 -3.12-8).
These mitigation measures require a study to be conducted identifying utilities, obtainment of
encroachment permits, development of procedures for excavation, support, and fill of areas
around utility cables and pipes, and notification of surrounding residents and businesses.
15
070403 syn 6050098
(2) Impact 3.12-2: Short-tenn emergency services impacts. As set forth
onpage 3.12-S of the Draft EIR, the Project has the potential to generate a short tenn increase in
demand for police and fire services if an accident were to occur as a result of the Project. This
impact is identified as potentially significant.
i. Mitigation Measure 3.12-2 (Draft EIR, p. 3.12-S). A copy of
the traffic control plan shall be provided to the relevant police and fire departments prior to
construction, and the City shall provide notice to the relevant departments prior to construction
of individual pipeline segments.
(3) Impact 3.12-3: Project implementation would increase power usage
needs. As set forth on pages 3.12-S and 3.12-9 of the Draft EIR, construction activities would
result in a commitment of natural resources through direct consumption of fossil fuels and use of
materials. Over the long-tenn, consumption of electricity and nonrenewable resources would
occur at the wells and pump stations. These impacts are identified as potentially significant.
i. Mitigation Measure 3.12-3 (Draft EIR, p. 3.12-9). The City
would be required to coordinate design and anticipated energy demands with the City of Palo
Alto Utilities Department, and must ensure that energy efficient equipment is used.
(4) The City Council hereby finds, detennines, and declares that,
pursuant to CEQA Guidelines section 15091(a)(1), changes or alterations have been required in,
lor incorporated into, the Project which avoid or substantially lessen the significant environmental
effects identified in the Final EIR. Specifically, the measures required by Mitigation Measures
3.12-1,3.12-2, and 3.12-3 substantially reduce the Project's public services and utilities impacts.
With this mitigation, the Project's above-identified public services and utilities impacts are
therefore found to be less-than-significant.
SECTION 7. Significant Impacts That Can be Avoided or Mitigated to a Less-Than-
Significant Level.
(a) Construction Related Impacts
(1) Impact 4.1: Concurrent construction of several Projects within the
Project area could result in cumulative short-tenn impacts associated with construction activities.
As set forth on pages 4 .. 10 to 4-14 of the Draft EIR, construction of the Project may result in
potentially significant construction related impacts.
i. Mitigation Measures 4.1 a, 4.1b, 3.3-la, 3.3-lb, 3.3-lc, 3.3-5a,
3.5-la, 3.5-lb, 3.6-3,3.6-4, 3.S-la, 3.S-lb, 3.S-lc, 3.S-ld, 3.S-le, 3.S-lf, 3.S-lg, 3.S-4a, 3.S-4b,
3.S-4c, 3.S-4d, 3.S-4e, 3.S-4f, 3.S-6, 3.9-la, 3.9-lb, 3.1O-la, 3.10-1b, 3.10-lc, 3.10-ld, 3.1O-le,
3.11-1, 3.1l-2a, 3.l1-2b, 3.11-2c, 3.12-1, 3.12-2 (Draft EIR, p. 4-14, as revised in the Final EIR
at pp. 5-19 to 5-20). These mitigation measures require communication and coordination of the
Project construction activities with other agencies in the area, and other such mitigation as is
described above in this Resolution.
16
070403 syn 6050098
(2) Impact 4.3: Concurrent construction of Projects could result in
cumulative long-term impacts to visual quality. As set forth on page 4-15 of the Draft EIR> the
Project and other Projects in the areas may contribute to permanent impacts to surrounding visual
resources. These impacts are identified as potentially significant.
i. Mitigation Measures 4.3, 3.3-2a, 3.3-2b, 3.3-5b (Draft EIR, p.
4-15). Mitigation Measure 4.3 requires implementation of Mitigation Measures 3.3-2a, 3.3-2b,
and 3.3-5b as described above in this Resolution.
(3) Impact 4.6: Concurrent construction of Projects could result in
cumulative long-term impacts to protected trees and other vegetation. As set forth on page 4-17
of the Draft EIR, the proposed Project, and other Projects in the area, may require removal of or
pruning of protected trees and shrubs. This impacts is considered potentially significant.
i. Mitigation Measures 3.6-2a, 3.6-2b, 3.6-2c, 3.6-2d (Draft EIR,
p. 4-17). This mitigation measure requires the implementation of Mitigation Measures 3.6-2a,
3.6-2b, 3.6-2c, and 3.6-2d, as described above in this Resolution.
(4) Impact 4.7: Concurrent construction of Projects could result in
cumulative long-term impacts to cultural resources. As set forth on pages 4-17 and 4-18 of the
Draft EIR, construction of the Project, and other Projects in the area may result in impacts to
known and unknown cultural resources.
i. Mitigation Measures 4.7, 3.7-1a, 3.7-1b, 3.7-2, 3.7-3 (Draft
EIR, p. 4-18). This mitigation measure requires the implementation of Mitigation Measures 3.7-
la, 3.7-lb, 3.7-2, 3.7-3, as described above in this Resolution.
(5) Impact 4.8: Concurrent construction of Projects could result in
cumulative long-term noise impacts. As set forth on page 4-18 of the Draft EIR, the Project, and
other Projects in the area, may result in potentially significant cumulative noise impacts.
i. Mitigation Measures 4.8, 3.1 0-3a, 3.1O-3b, 3.10-3c (Draft
EIR, p. 4-18). This mitigation measure requires the implementation of Mitigation Measures
3.10-3a, 3.1O-3b, and 3.l0-3c, as described above in this Resolution.
(6) Impact 4.9: Concurrent construction of Projects could result in a
cumulative long-term increase in power usage. As set forth on page 4-19 of the Draft EIR, the
Project, and other Projects in the area may contribute to long-term increases in power usage.
This impact is identified as a potentially significant cumulative impact.
i. Mitigation Measures 4.9, 3.12-3 (Draft EIR, p. 4-19). This
mitigation measure requires the implementation of Mitigation Measure 3.12-3, as described
above in this Resolution.
(7) The City Council hereby finds, determines, and declares that,
pursuant to CEQA Guidelines section 15091(a)(1), changes or alterations have been required in,
17
070403syn 6050098
or incorporated into, the Project which avoid or substantially lessen the significant environmental
effects identified in the Final EIR. Specifically, the measures required by Mitigation Measures
4.1a, 4.1 b, 4.3, 3.6-2a, 3.6-2b, 3.6-2c, 3.6-2d, 4.7, 4.8, and 4.9 substantially reduce the Project's
long-term cumulative impacts. With this mitigation, the Project's above-identified long-term
cumulative impacts are therefore found to be less-than-significant.
SECTION 8. Growth Inducement.
(a) Growth can be induced in a number of ways, including through the
elimination of obstacles to growth and development. The removal of obstacles to growth relates
directly to the removal of infrastructure limitations. The proposed Project is intended to correct
an existing deficiency in the City's emergency water supply and provide for water supply during
certain drought conditions. As set forth in Chapter 6 of the Draft EIR, the City Council hereby
fmds that implementation of the Project would not directly foster population growth or result in
the construction of additional housing, and that implementation of the proposed Project would
not result in a direct or indirect increase in population or employment.
SECTION 9. Significant and Unavoidable Impacts.
As found by the City Council in sections V and VII above, the Final EIR identifies
the following potentially significant impacts that cannot be fully avoided or substantially
lessened by the above-referenced mitigation measures.
(a) Impact 3.8-4: Short-term demand for parking spaces. As set forth on pages
3.8-19 to 3.8-22 of the Draft EIR, the permanent loss of parking spaces at the California Avenue
parking lot site would result in a significant unavoidable impact.
(b) Impact 3.10-1: Construction of proposed facilities would generate temporary
noise levels above existing ambient conditions and well drilling activities, resulting in City
Municipal Code Violations. As set forth on pages 3.1 0-11 to 3.1 0-14 of the Draft EIR, impacts
associated with 24-hour drilling activities would be significant and unavoidable.
SECTION 10. Feasibility of Project Alternatives.
(a) Because the Project will result in potentially significant environmental
impacts, the City of Palo Alto must consider the feasibility of any environmentally superior
alternative to the Project.
(b) As described in detail on page 5-3 of the Draft EIR, under the no-Project
alternative, the City of Palo Alto would not implement improvements to correct the existing
deficiency in emergency water supply. As such, the potentially significant environmental
impacts identified in the Final EIR would be avoided.
(1) The City Council hereby finds, determines, and declares that this
alternative is infeasible and less desirable than the Project and rejects this alternative for the
following reasons: (a) the Project will provide many benefits, as described below in Section XI,
18
070403 syn 6050098
and these benefits would not be obtained if this alternative were selected; and (b) this. alternative
will not satisfy any ofthe stated Project objectives.
(c) As described in detail on pages 5-3 to 5-6 of the Draft EIR, the Agency
Connections alternative would use existing connections with the City of Mountain View,
Stanford University and East Palo Alto to obtain additional water supply. As the intertie
connections to adjacent utility districts are already in place, no additional facilities would be
required, and no environmental impacts would be associated with implementation of this
alternative.
(l) The City Council hereby finds, determines, and declares that this
alternative is infeasible and less desirable than the Project and rejects this alternative for the
following reasons: (a) the Project will provide many benefits, as described below in Section XI,
and these benefits would not be obtained if this alternative were selected; and (b) this alternative
would not satisfy the Project objectives of meeting the 8-hour emergency water supply and fire
flow requirements.
(d) As described in detail on pages 5-6 to 5-10 of the Draft EIR, the Santa Clara
Valley Water District Western Pipeline Extension would extend a supply pipeline from the City
of Mountain View to the City of Palo Alto to assist in meeting the City of Palo Alto's emergency
water supply demand. Construction of the approximately 15 mile pipeline would result in
substantial construction related impacts.
(1) The City Council hereby finds, determines, and declares that this
alternative is infeasible and less desirable than the Project and rejects this alternative for the
following reasons: (a) the Project will provide many benefits, as described below in Section XI,
and these benefits would not be obtained if this alternative were selected; (b) this alternative,
which would result in a total disturbance area of approximately 77 acres over an 18 mile linear
corridor would result in the highest overall environmental impacts; and (c) this alternative
would not meet the Project's fire flow objective.
(e) As described in detail on pages 5-10 to 5-16 of the Draft EIR, the
Desalination Plant alternative would result in construction of a desalination plant to meet
emergency demands. Construction of a desalination plant would result in short-term
construction related impacts and long-term operational impacts.
(1) The City Council hereby finds, determines, and declares that this
alternative is infeasible and less desirable than the Project and rejects this alternative for the
following reasons: (a) the Project will provide many benefits, as described below in Section XI,
and these benefits would not be obtained if this alternative were selected; and (b) this alternative,
which would require a 10 to 15 acre site and 4.5 miles of distribution system would result in
greater environmental impacts across all issue areas.
(t) The City Council hereby certifies that the Final EIR describes a reasonable range of
alternatives to the Project sufficient to foster informed public participation and decisionmaking
and permit a reasoned choice. As set forth above, the City Council has evaluated the
19
070403syn 6050098
I
comparative merits of the alternatives, found each of the alternatives infeasible, and has rejected
them in favor of the Project.
SECTION 11. Statement of Overriding Considerations.
(a) As set forth elsewhere in this Resolution, the City Council has found (and the
Final EIR concludes) that the proposed Proj ect, even with incorporation of all feasible mitigation
measures and consideration of alternatives, will potentially result in significant, unavoidable
parking and noise impacts.
(b) The City Council hereby adopts and makes this statement of overriding
considerations concerning the Project's significant and unavoidable parking and noise impacts to
explain why the Project's health, safety, and welfare benefits override and outweigh its
unavoidable impacts.
(c) The Project will bring substantial benefits to the City of Palo Alto, in that the
Project provides emergency water supply and storage necessary for the City to meet the
Department of Health Services recommended eight-hour emergency supply to be provided in the
event of a failure in the Hetch Hetchy water delivery system. Additionally, the Project will
provide emergency water supply and storage necessary for the City to meet fire flow
requirements in every pressure area, and includes facilities that would allow for drought year
supplemental production.
(d) As set forth in the 1999 Water Wells, Regional Storage, and Distribution
System Study (which is incorporated herein by reference), a large earthquake could result in the
shutdown of the City's main water supply for as long as 60 days. Coupled with the need to
extinguish multiple fires in the hour immediately following such an earthquake, the City's
existing water system would not be able to supply sufficient water to meet demands, even if
extensive water conservation measures were implemented during the disaster. The 1999 study
concluded that the best way to provide for basic water needs would be to implement the Project.

appropriate control measures.
Install temporary (or permanent) storm water retention or detention structures in
which treatment can occur.
No stockpiling of excavated soli or other materials shall occur In stream channels. No
excavated soil or other materials shall be disposed of in stream channels, but should
be hauled away for proper disposal. Care should be taken to ensure that pollutant
spills do not occur in stream channels. For example, changing of oil or other fluids
should not be performed in the vicinity of stream channels.
Use tarps to cover any excavation soils storage during the October-April rainy period.
• After completion of slope grading, erosion protection shall be provided and must
include slope planting. Revegetation shall be facilitated by mulching, hydroseedlng or
other methods, and shall be Initiated as soon as possible after completion of grading,

MITIGATION MONITORING AND REPORTING PLAN FOR THE CITY OF PALO ALTO EMERGENCY WATER SUPPLY AND STORAGE PROJECT (Continued)
Mitigation Measures
Measure 3.6-3 (applies to all project components): Avoid disturbance of breeding
special-stetus birds. If conslruction activities (I.e .• ground clearing and grading, including
removal of trees or shrubs) are scheduled to occur during the nonbreeding season
(September 1 through January 31), no mitigation is required.
If construction activities are scheduled to occur during the breeding season (February 1
through August 31), the project proponent will implement the following measures to avoid
potential adverse effects on nesting rapters and other special-status birds:
No more than two weeks prior to construction. a qualified wildlife biologist will conduct
preconstruction SUlVeys of all potential nesting habitat within 500 feet of construction
activ~ies where access is available,
If active nests are found during preconstruction sUlVeys, the project proponent will
create a no-disturbance buffer (acceptable in size to the CDFG) around active raptor
nests and nests of other special-status birds during the breeding season, or until it is
determined that all young have fledged. Typical buffers include 500 feet for raptors
and 250 feet for other nesting birds. The size of these buffer zones and types of
construction activities restricted in these areas may be further modified during
coordination with CDFG and will ba based on existing noise and human disturbance
levels at the project site, Nests initiated during construction are presumed to be
unaffected. and no buffer would be necessary. However. the "take" (mortality, direct
disturbance Of. etc,) of Individual birds will be prohibited.
If preconstruction sUlVeyS indicate that nests are Inactive or potential habitat is
unoccupied during the construction period. no further mitigation is required, Trees and
shrubs within the construction footprint that have baen determined to ba unoccupied
by special-status birds or that are located outside the no-disturbance buffer for active
nests may ba removed,
Measure 3.64 (applies to Hale Well, Fernando Well, Matadero Well, Eleanor Pardee
Well, EI Camino Reservoir, Stanford Shopping Center North Reservoir, and Mayfield
Pump Station sites): Project implementation shall avoid disturbance to maternity roosts
of special-status bats during the breeding season in accordance with the following
procedures. No more than two weeks in advance of any tree removal or demolition or
construction activity involving noisy or intrusive activities, thet will commence during the
breeding season (March 1 through August 31). a qualified bat biologist, acceptable to the
CDFG, shall conduct daytime pre-<:onstruction surveys of all potential special-status bat
breeding habitat in the vicinHy of the planned activity. Under such surveys. potentially
suitable habitat shall be located visually. In addition. night surveys shall be conducted to
detect potential bal roost emergence activity from any suitable habitat. Night surveys shall
be conducted using night vision equipment and/or infrared-capable video cameras. In
addition. the qualified bat biologist shall be proficient in bioacoustic analysis using
ultrasonic detectors. and will use a sufficient number of acoustic detectors to indicate any
areas of bat activity, At least four nighttime emergence surveys shall be undertaken on
nights that are warm enough for bats to be active, as determined by a qualified bat
biologist. SUlVeys should provide. as much as possible, data on species, population, roost
location. and foraging activity. Depending on the survey findings, the following actions
shall be taken to avoid potential adverse effects on breeding special-status bats:
1. If active roosts are identified during pre-<:onstruction SUlVeys, a no-disturbance buffer
will be created by the qualified bat biologist in consultation with the CDFG, around
active roosts during the breeding season, The size of the buffer will take into account
factors such as the following:
a. Noise and human disturbance levels at the project site and the roost site at the
time of the sUlVey and the noise and disturbance expected during the
construction activity;
b. Distance and amount of vegetation or other screening between the project site
and the roost; and
c. Sensitivity of individual nesting species and the behaviors of the bats.
2. If pre-<:onstructlon surveys indicate that no roosts of special-status bats are present.
or that roosts are inactive or potential habitat is unoccupied. no further mitigation is
required.

Mitigation Measures
3. Pre-construction surveys are not required for demolition or construction activities
scheduled to occur during the non-breeding season (September 1 through
February 28).
4. Noisy demolition or construction activnies as described above (or activities producing
similar noise and activity levels in the vicinity) commencing during the non-breading
season and continuing into the breeding season do not require surveys (as It is
assumed that any bats taking up roosts would be acclimated to project-relaled
activities already under way). However, If trees are to be removed during the breeding
season, the trees would be surveyed for roosts prior to their removal, according to lhe
guidelines outlined In 1a through 1c, above.
5. Bat roosts Initiated during demolition or construction activities are presumed to be
unaffected by the activity, and a buffer is not necessary.
6. Destruction of roosts of speclal-status bats and overt interference with roosting
activ~ies of special-status bats shall be prohibited.
Cultural Resources
Measure 3.7·1a (applies to all project components): The Cfty of Palo Alto will Include
the following in the proposed project contract specifications for ground-dlsturbing
activities, including excavation and grading:
• In the event that any prehistoric or historic subsurface cultural resources are
discovered during ground disturbing activities, such as structural features or unusual
amounts of bone or shell, artifacts, human remains, architectural remains (such as
bricks or other foundation elements), or historic archaeological artifacts (such as
antique glass boWes, ceramics, horseshoes, etc.), all work within 1OQ-feet of the
resources shall be haKed and the project proponent and/or lead agency shall consult
with a qualified archaeologist or paleontologist to assess the significance of the find. If
any find is determined to be Significant, representatives of the project proponent
and/or lead agency and the qualified archaeologist and/or paleontologist would meet
to determine the appropriate avoidance measures or other appropriate mitigation, with
the ultimate determination to be made by the City. If recommended by the consu~ing
archaeologist, all significant cultural materials recovered shall be subject to scientific
analysis, professional museum curation, and a report prepared by the qualified
archaeologist according to current professional standards.
In conSidering any suggested mitigation proposed by the consulting archaeologist in
order to mitigate impacts to historical resources or unique archaeological resources,
City Planning Staff shall determine whether avoidance is necessary and feasible in
light of factors such as the nature of the find, project design, costs, and other
considerations. If aVOidance is unnecessary or infeasible, other appropriate measures
(e.g., data recovery) shall be instituted. Work may proceed on other parts of the
project site while mitigation for historical resources or unique archaeological
resources is carried out.
• If the discovery includes human remains, CEQA Guidelines 15064.5 (e){1) shall be
followed, which is as follows:
(e) In the event of the accidental discovery or recognition of any human remains in
any location other than a dedicated cemetery, the following steps should be
taken:
(1) There shall be no further excavation or disturbance of the site or any
nearby area reasonably suspected to overlie adjacent human remains until:
(A) The coroner of the county In which the remains are discovered must
be contacted to determine that no investigation of the cause of death
Is required, and
(B) If the coroner determines the remains to be Native American:
The coroner shall contact the Native American Heritage
Commission within 24 hours.

(6) The descendant identified fails to make a recommendation; or
(C) The landowner or his authorized representative rejects the
recommendation of the descendant, and the mediation by the Native
American Heritage Commission fails to provide measures acceptable
to the landowner,
Measure 3.7-1b (applies to EI Camino Park, Stanford Shopping Center North, and
Stanford Shopping Center South reservoir components): The City of Palo Allo will
retain the services of a qualified archaeological consu~ant that has expertise in California
prehistory to monitor ground-disturbing or vegetation removal activity within areas
determined to have high potential for unknown or poony documented archaeological
resounces, If an intact archaeological deposit is encountered, all soll-disturbing activities in
the vicinity of the deposit will cease, The archaeological monitor will be empowered to
temporarily redirect crews and heavy equipment until the deposit is evaluated, The
monitor will immediately notify the City of Palo AKo of the encountered archaeological
deposit. The monitor will, after making a reasonable effort to assess the identity, integrity,
and significance of the encountered archaeological deposit, present the findings of this
assessment to the City of Palo Alto, If the archaeological monitor determines that the area
being excavated does not contain archaeological materials, the monitor will modify the
level of monitoring as needed, That is, at the discretion of the on-site archaeologis~ the
monitoring conducted can be continuous, intenmillent, or spot-check only,
If the City of Palo Alto, In consultation with the archaeological mon~or, detenmines that a
significant archaeological resource is present and that the resource could be adversely
affected by the proposed project, the City of Palo Alto will:
Redesign the project to avoid any adverse effects on the significant archaeological
resource; or
• Implement an archaeological data recovery program (ADRP) (unless the
archaeologist detenmines that the resource is of greater interpretive than research
significance and that interpretive use of the resource is feasible), If the circumstances
warrant an archaeological data recovery program, an ADRP will be conducted, The
project archaeologist and the City of Palo Alto will meet and consult to detenmine the
scope of the ADRP, The archaeologist will prepare a draft ADRP that will be
submitted to the City of Palo Alto for review and approval. The ADRP will identify how
the proposed data recovery program would preserve the significant infonmalion the
archaeological resource is expected to contain (i.e" the ADRP will identify the
scientificlhlstorical research questions that are applicable to the expected resource,
the data classes the resource is expected to possess, and how the expected data
classes would address the applicable research questions), Data recovery, in general,
should be limited to the portions of the historical property that could be adversely
affected by the proposed project. Destructive data recovery methods will not be
applied to portions of the archaeological resources if nondestructive methods are
practical.
