Exhibit A
FINDINGS OF FACT IN SUPPORT OF FINDINGS FOR THE
FINAL ENVIRONMENTAL IMPACT REPORT
FOR THE
CITY HALL AND PARK DEVELOPMENT PLAN
NEWPORT BEACH, CALIFORNIA
STATE CLEARINGHOUSE NO, 2009041010
BACKGROUND
California Environmental Quality Act (CEQA) provides that "public agencies should not approve projects
as proposed if there are feasible alternatives or feasible mitigation measures available which would
substantially lessen the significant environmental effects of such projects[.]" (Public Resources Code
section 21002.) The same statute provides that the procedures required by CEQA "are intended to assist
public agencies in systematically identifying both the significant effects of projects and the feasible
alternatives or feasible mitigation measures which will avoid or substantially lessen such significant
effects." Section 21002 goes on to provide that "in the event [that] specific economic, social, or other
conditions make infeasible such project alternatives or such mitigation measures, individual projects may
be approved in spite of one or more significant effects thereof."
Thus, CEQA requires decision makers to balance the benefits of the proposed project against its
unavoidable environmental risks when determining whether to approve the project. If the benefits of the
project outweigh the unavoidable adverse effects, those effects may be considered "acceptable" (State
CEQA Guidelines Section 15093[a].). CEQA requires the agency to support, in writing, the speck
reasons for considering a project acceptable when significant impacts are infeasible to mitigate. Such
reasons must be based on substantial evidence in the Final Environmental Impact Report (EIR) or
elsewhere in the administrative record (State CEQA Guidelines Section 15093 [b]). The agency's
statement is referred to as a "Statement of Overriding Considerations" The following sections provide a
description of the each of the project's environmental impacts. For potentially significant impacts, these
findings provide that all feasible mitigation has been adopted to lessen those impacts. This section also
provides a description of the impacts for which no feasible mitigation or alternative exist that will render
the impact less than significant. The section describes those significant and unavoidable adverse
impacts and the justification for adopting a statement of overriding considerations.
A. PROJECT SUMMARY
The proposed project would result in the relocation of the City of Newport Beach (City) functions (except
for Fire Station No. 2) currently taking place at the existing City Hall located at 3300 Newport Boulevard to
the proposed project site. The proposed project site is located in the City between Avocado Avenue and
MacArthur Boulevard. The proposed project includes eight primary components, including:
(1) construction and operation of an approximately 98,000- square -foot (sf) City Hall administration
building, Community Room, and Council Chambers; (2) a 450 -space parking structure; (3) an
approximately 17,000 sf expansion of the Newport Beach Central Library (Library); (4) a dedicated
4,800 sf Emergency Operations Center (EOC); (5) a Civic Green; (6) construction of a 14.3 -acre (ac)
public park that includes a dog park, wetlands area, bridges over the wetlands, lookouts, and a pedestrian
overcrossing over San Miguel Drive; (7) widening of San Miguel Drive; and (8) reuse of the existing City
Hall structures located at 3300 Newport Boulevard with public facilities uses. Throughout the EIR and the
following Findings of Fact, project components 1 -5 are collectively referred to as the Civic Center.
The following objectives have been established for the Newport Beach City Hall and Development Plan
project and will aid decision - makers in their review of the project and associated environmental impacts:
City Hall and Park Development Plan
CEQA Findings of Fact
Page 1
1. Implement the February 2008, voters' approval of Measure B for a new City Hall, including the City
Hall administration building, Community Room, Council Chambers, and a parking structure on City -
owned property located between MacArthur Boulevard and Avocado Avenue.
2. Incorporate the proposed City Hall into an overall Civic Center Complex at the proposed project site,
which would include a Library Expansion, a dedicated EOC, and a Civic Green. A park and a
pedestrian overcrossing linking the park areas on the northern parcel with the park areas on the
central and southern parcels should also be constructed.
3. Accommodate the relocation of all existing City Hall uses to the proposed project site, with the
exception of the Fire Station.
4. Implement Policy R.1.9 of the City's General Plan by developing a passive park (a park without sports
fields) that is integrated with the proposed Civic Center Complex.
5. Integrate the 3.24 ac parcel (northern parcel) located between MacArthur Boulevard and Avocado
Avenue, and north of San Miguel Drive, as a portion of the proposed public park and incorporate
features that will encourage use of the proposed project site.
6. Provide adequate on -site parking and circulation for all City vehicles, employee vehicles, and visitors
of the new Civic Center Complex uses.
7. Minimize costs to the City by developing the proposed Civic Center Complex on a site that does not
require the condemnation of private property or result in excessive site acquisition costs to the City
and that requires minimal demolition and tenant relocation.
8. Preserve and enhance the existing on -site wetlands.
9. Protect and enhance public views to the ocean and harbor from MacArthur Boulevard by maintaining
the existing Sight Plane above the proposed project site and providing lookouts in the park plan.
10. Improve public infrastructure on and near the proposed project site, including adjacent roadways, to
both serve on -site uses and to enhance operations in the vicinity of the project.
11. Incorporate sustainable features into the project via innovative design techniques to achieve energy
savings, water efficiency, potable water use reduction, carbon dioxide emissions reduction,
operational cost savings, and improved indoor environmental quality compared to conventional
construction.
12. Construct a dedicated EOC to allow better and faster citywide and regional coordination of response
to emergency events, including earthquakes, fires, floods, tsunamis, and air disasters.
13. Expand the capacity of the Newport Beach Central Library and create a distinct linkage between the
Library and the Civic Green, the parking structure, the Community Room, and the City Hall
administration building to promote use of the facilities and create a unified campus through design
features, including a second entry into the Library, food concession, credit union, drop -off area,
shared parking, and landscaping.
B. ENVIRONMENTAL REVIEW PROCESS
In conformance with CEQA, the State CEQA Guidelines, and the City of Newport Beach CEQA
Guidelines, the City conducted an extensive environmental review of the proposed project.
City Hall and Park Development Plan
CEQA Findings of Fad
Page 2
The City determined that an EIR would be required for the proposed project and issued a Notice of
Preparation (NOP) and Initial Study on April 1, 2009. Section 2.2 of the Draft EIR (DEIR) describes
the issues identified for analysis in the DEIR through the Initial Study, NOP, and public scoping
process.
• Based upon the Initial Study and Environmental Checklist Form, the City staff determined that a DEIR
should be prepared for the proposed project. The scope of the DEIR was determined based on the
City's Initial Study, comments received in response to the NOP, and comments received at the
scoping meeting conducted by the City.
• The City prepared a DEIR, which was made available for a 45 -day public review period, beginning
September 1, 2009, and ending October 15, 2009. The City prepared a Final EIR (FEIR), including
the Responses to Comments to the DEIR, the Findings of Fact, and the Statement of Overriding
Considerations. The FEIR/Response to Comments contains comments on the DEIR, responses to
those comments, revisions to the DEIR, and appended documents.
• The City held public hearings on the proposed project on November 24, 2009.

compliance with Public Resources Code Section 21081.6(a)(2) and Guidelines Section 15091(e).
II. FINDINGS OF FACT
A. ENVIRONMENTAL EFFECTS WHICH WERE DETERMINED NOT TO BE POTENTIALLY
AFFECTED BY THE PROPOSED PROJECT
As a result of the Initial Study that was circulated with the NOP by the City on April 1, 2009 (see EIR
Appendix A), the City determined, based upon the threshold criteria for significance, that the project
would not result in significant potential environmental impacts in several areas; therefore, the City
determined that these potential environmental effects would not be addressed in the DER. Based upon
the environmental analysis presented in the FEIR, and the comments received by the public on the DEIR,
no substantial evidence has been submitted to or identified by the City that indicates that the project
would have an impact on the following environmental areas:
Agricultural Resources. The proposed City Hall site is not designated as Prime Farmland, Unique
Farmland, or Farmland of Statewide Importance. In addition, the City's Land Use Element of the General
Plan designates the proposed project site as Public Facility (PF) and Open Space (OS). The proposed
project site is not zoned or used for agricultural use, and no Williamson Act contracts exist for the site.
The proposed City Hall site is primarily vacant (with the exception of the existing Library), but is not used
for agricultural purposes, and is surrounded by commercial and residential development. The proposed
project would not result in the conversion of farmland to nonagricultural use. As a result, no impacts are
anticipated.
Mineral Resources. The proposed project site is not located in any of the mineral resource areas
identified in the Citys General Plan (i.e., the Newport Oil Field or the West Newport Oil Field). Portions of
the project site have been classified by the California Department of Mines and Geology (CDMG) as
being located in MRZ -1 and MRZ -3,' indicating that the project site is located in an area where no
significant mineral deposits are present or in an area containing mineral deposits, the significance of
which cannot be evaluated.
As previously stated, the proposed project site is largely vacant, with the exception of the existing Library.
There are no mineral extraction activities occurring on site. In addition, the project site is designated for
PF and OS uses. The proposed project would not result in the loss of a valuable commercial or locally
important mineral resource. No significant impacts related to known mineral resources would result from
project implementation.
Land Use: Dividing an Established Community. The proposed project includes the construction and
operation of City Hall, a Library expansion, and a public park on an approximately 20 ac site. The
proposed project site is located between two existing roadways (MacArthur Boulevard and Avocado
Avenue) and is surrounded on all sites by existing development. The proposed project would not disrupt
or realign the existing roadway network or affect or disrupt residential neighborhoods in the project
vicinity. Therefore, the proposed project would not physically divide an established community, and no
significant impacts are anticipated.
Land Use: Conflict with any applicable habitat conservation plan. The Central /Coastal Orange County
Subregion Natural Communities Conservation Plan /Habitat Conservation Plan (NCCP /HCP) provides for
the protection of a number of plant and animal species. The proposed project site is located within the
MRZ -1 is defined as an area where adequate information indicates that no significant mineral
deposits are present, or where it is judged that little likelihood exists for their presence. MRZ -3 is
defined as an area containing mineral deposits, the significance of which cannot be evaluated.
City Hall and Park Development Plan
CEQA Findings of Fact

boundaries of the NCCP /HCP. The project is in an area identified as urbanized by the NCCP /HCP and is
not located in the Reserve or other planned open space area. Therefore, the project is consistent with the
provisions of the plan, as it allows development of non - Reserve areas.
Traffic and Circulation: Result in a change in air traffic patterns. The proposed project is located 4.37
miles (mi) from John Wayne Airport (JWA). A small portion of the proposed project site on Avocado
Avenue is located within the Airport Environs Land Use Plan (AELUP) for JWA. The AELUP contains
policies governing the land uses within the JWA area. Specifically, these policies establish development
criteria that protect sensitive receptors from airport noise, persons from risk of operations, and height
guidelines to ensure aircraft safety. As previously stated, the proposed project would be required to
implement the guidelines contained in the AELUP. The airspace over the project site could be used by
commercial aircraft and helicopters; however, both would be at sufficient altitude so as not to be affected
by the proposed project. In addition, the proposed project site is outside the noise contours and safety
zones for JWA.
Cultural Resources: Result in a substantial adverse change to a historical resource. The proposed project
site is currently vacant (with the exception of the existing Library), and there are no existing structures on
or adjacent to the proposed project site that are over 50 years of age or considered to be historically
significant. The City General Plan does not identify any historic resources within or adjacent to the project
site. Therefore, the proposed project would not cause a substantial adverse change to historical
resources.
Geology and Soils: Septic tanks. The project does not include the use of septic tanks or alternative
methods for disposal of wastewater into the subsurface soils. The proposed project would connect to
existing public wastewater infrastructure. No on -site sewage disposal systems (e.g., septic tanks) are
planned. Therefore, the project would not result in any impacts related to septic tanks or alternative
wastewater disposal methods.
Hazards and Hazardous Materials: Vicinity of a private airstrip. The proposed project site is not located in
the vicinity of a private airstrip, and the proposed project would not result in a safety hazard for people
residing or working in the project area.
Hazards and Hazardous Materials: Wildfires. The City defines a wildland fire hazard area as any
geographic area that contains the types and conditions of vegetation, topography, weather, and structure
density that potentially increase the possibility of wildland fires. The area surrounding the proposed
project site is surrounded by urban commercial and residential uses that do not contain the brush- and
grass- covered hillsides often associated with wildfires. According to the City's General Plan (Figure S4),
the proposed project is located in an area designated as "low /none wildfire hazard." Therefore, the project
would not expose people or structures to a significant risk of loss, injury, or death involving wildland fires.
Hydrology and Water Quality: Place housing in a flood hazard area. The project site is located outside of
Flood Hazard Areas determined by the Federal Emergency Management Agency (FEMA). The project
site is located in Zone X (outside the 2 percent annual floodplain) on FEMA Flood Control Maps.
Therefore, the project would not place housing or structures within a 100 -year flood zone.
Hydrology and Water Quality: Place structures in a flood hazard area. The project site is located outside
of Flood Hazard Areas determined by FEMA. The project site is located in Zone X (outside the 2 percent
annual floodplain) on FEMA Flood Control Maps. Therefore, the project would not place housing or
structures within a 100 -year flood zone.
Hydrology and Water Quality: Flooding as a result of the failure of a levee or dam. The proposed project
site is not located within a Flood Hazard Zone (100 -year flood zone or 500 -year flood zone) as identified
in the City's General Plan (Figure S3).
City Hall and Park Development Plan
CEQA Findings of Fact
Page 5
Hydrology and Water Quality: Inundation by seiche tsunami, or mudflow. The City is susceptible to low -
probability but high -risk events such as tsunamis, and, more common, isolated hazards such as storm
surges and coastal erosion. Each of these has a potential to significantly impact Newport Beach residents
and the built environment. Areas within Newport Beach that are most likely to be impacted by a tsunami
and flooding include West Newport, Balboa Peninsula, Lido Isle, Balboa Island, and Upper Newport Bay.
The project site is not located in an area of the City likely to be impacted by tsunami or flood events. In
addition, there are no standing bodies of water in the vicinity of the proposed project site that could cause
flooding due to seiches. Therefore, the project would not expose people or structures to a significant risk
of loss, injury, or death involving flooding or inundation by seiche, tsunami, or mudflow.
Noise: Airport land use plan. Newport Beach is located immediately south of JWA and is under the
primary departure corridor. A small portion of the project site is located within the AELUP for JWA. The
AELUP contains policies governing the land uses within the JWA area. Specifically, these policies
establish development criteria that protect sensitive receptors from airport noise, persons from risk of
operations, and height guidelines to ensure aircraft safety. As previously stated, the proposed project
would be required to implement the guidelines contained in the AELUP. Although aircraft noise can be
heard throughout Newport Beach, the highest noise levels are experienced just south of JWA, in the
Airport Area, Santa Ana Heights Area, Westcliff, Dover Shores, the Bluffs, and Balboa Island, and are
generated by aircraft departures. The proposed project site is located approximately 4.37 mi from the
airport and is outside the 60 A- weighted decibels (dBA) CNEL for JWA; permissible exterior noise
thresholds would not be exceeded. Also, building materials will provide adequate shielding to lower
aircraft - related noise below interior threshold levels with windows and doors open. Therefore, the
proposed project would not be expected to expose people working on site to excessive noise levels
related to its proximity to JWA.
Noise: Private airstrip. The proposed project site is not located in the vicinity of a private airstrip. Hoag
Hospital operates a helicopter and helipad located approximately 3.5 mi from the project site. The helipad
is located on the roof of the emergency area of the hospital. The proposed project site is not located near
Hoag Hospital and is not expected to be affected by helicopter noise. Because the project is not located
within the vicinity of a private airstrip, no potential impacts are anticipated.
Housing. Population. and Employment: Displace substantial numbers of exiting housing. The proposed
project will not displace any existing housing or displace a substantial number of people. The northern
and central parcels of the proposed project site are currently vacant. The southern parcel of the proposed
project site is occupied by the existing Newport Beach Public Library; the Library will remain after project
implementation.
Housing, Population, and Employment: Displace substantial numbers of people. The proposed project will
not displace any existing housing or displace a substantial number of people. The northern and central
parcels of the proposed project site are currently vacant. The southern parcel of the proposed project site
is occupied by the existing Newport Beach Public Library; the Library will remain after project
implementation.
B. ENVIRONMENTAL EFFECTS WHICH WERE DETERMINED TO BE LESS THAN
SIGNIFICANT
Impact: Result in a cumulatively considerable contribution to a significant land use impact.
Development of the proposed project would be consistent with the existing General Plan land use
designation. The conversion of the proposed project site from vacant land to a passive park and Civic
Center complex would not result in a potential inconsistency with the City General Plan or other land
planning documents, nor would the proposed project result in significant land use compatibility issues. As
with the proposed project, cumulative projects would be subject to compliance with the local and regional
plans reviewed in this section. Therefore, implementation of the proposed project would not result in, or
contribute to, a cumulatively significant land use impact.
City Hall and Park Development Plan
CEQA Findings of Fact
Page 6
Impact: Exceed, either individually or cumulatively, a level of service standard established by the
county congestion management agency for designated roads or highways. Project and cumulative
impacts were analyzed for the Congestion Management Plan (CMP) monitored intersections in
accordance with the CMP guidelines. The addition of project - generated trips is not forecast to result in
significant impacts at the CMP study intersections for: 1) existing plus project traffic; 2) forecast year 2013
with committed projects with project traffic; 3) forecast year 2013 with committed and cumulative projects
with project traffic; and 4) for forecast General Plan build out with project traffic. Therefore, impacts to
level of service standards set by the county congestion management agency associated with the
proposed project are considered less than significant.
Impact: Result in inadequate emergency access. Emergency vehicles would have access to the site at
the main entrance at the intersection of Avocado Avenue and Farallon Drive, from the entrance to the
Library along Avocado Avenue south of Farallon Drive, and to the loading dock along Avocado Avenue.
In addition, a fire /medical emergency entrance from MacArthur Boulevard to the top level of the parking
structure would be available to emergency vehicles only. Therefore, the proposed project would not inhibit
or reduce emergency access to the project site. There are no impacts to emergency access associated
with the proposed project.
Impact: Result in inadequate parking capacity. The proposed project would provide 495 parking
spaces which would not exceed projected parking demand for onsite uses. Therefore, the proposed
project would not result in a significant impact related to parking demand.
Impact: Conflict with adopted policies, plans, or programs supporting alternative transportation
(e.g., bus turnouts, bicycle racks). Because existing routes in the vicinity of the proposed project are
operating within capacity and additional ridership resulting from the proposed project could be
accommodated, no significant impacts to public transportation services are anticipated. In addition, the
proposed project would not conflict with or impact adopted policies, plans, or programs supporting
alternative transportation.
Impact: Substantial diverse effect on a scenic vista. Implementation of the proposed project would
modify the views to and from the project site by developing the proposed park and constructing the Civic
Center complex. The proposed project would not result in adverse impacts to existing ocean or harbor
views from the proposed on -site vantage points and adjacent roadways and sidewalks. Motorists along
Avocado Avenue, MacArthur Boulevard, and San Miguel Drive (the City- designated Coastal View Roads
and Public View Corridors) would maintain scenic views of the Pacific Ocean, harbor, and Santa Catalina
Island with implementation of the proposed project. Therefore, the project's impact on scenic vistas,
scenic resources, and views to and from the City- designated Coastal View Roads would be less than
significant.
Impact: Substantially damage scenic resources, including, but not limited to, trees, rock
outcroppings, and historic buildings within a state scenic highway. There are no City- designated
scenic resources (i.e. trees, rock outcroppings, etc) on site. Furthermore, the Pacific Coast Highway is not
a State - designated Scenic Highway, in the vicinity of the proposed project site Therefore, there are no
potential impacts of the proposed project on trees, rock outcroppings, historic buildings and state scenic
highways associated with the proposed project.
Impact: Substantially degrade the existing visual character or quality of the site and its
surroundings. The proposed project would permanently alter the existing visual character and quality of
the proposed project site by converting what is currently an undeveloped site to a graded, landscaped,
and developed Civic Center and park. While the proposed project would permanently alter the visual
conditions of the proposed project site, the changes would not substantially degrade the visual character
or quality of the site and its surrounding. Project impacts related to the visual character or quality of the
site and its surroundings would be are less than significant.
City Hall and Park Development Plan
CEQA Findings of Fad
Page 7
Impact: Result in a cumulatively considerable contribution to a significant aesthetics impact.
Several projects are planned within the City, however, none of these projects are proposed within the
viewshed of the proposed project site and therefore the proposed project would not contribute to
cumulative impacts related to viewsheds or visual character In addition, the proposed project would not
result in a cumulatively considerable contribution to nighttime lighting conditions because project features
and mitigation measures have been identified to reduce project - related impacts to a less than significant
level. Also, the project site is located in an urbanized area, and the incremental contribution of project
lighting after mitigation would not constitute a substantial change to the cumulative nighttime light
conditions.
Impact: Conflict with or obstruct implementation of the applicable air quality plan. The proposed
project emissions would be below the emissions thresholds established in South Coast Air Quality
Management District's (SCAQMD) CEQA Handbook. Therefore, the project would not conflict with the Air
Quality Management Plan (AQMP), and no significant impact would result with respect to implementation
of the AQMP.
Impact: Violate any air quality standard or contribute to an existing or projected air quality
violation.
Operation emissions. The project's emissions (both stationary sources and vehicular sources) would not
exceed the SCAQMD daily emissions thresholds. Therefore, the long -term air quality impacts of the
proposed project would be less than significant.
Long -Term Microscale (Carbon Monoxide FCO1 Hot Spot) Analysis. None of the nine intersections
analyzed would have 8 -hour CO concentration exceeding the federal and State ambient air quality
standards (AAQS) of 9 parts per million (ppm). The 1 -hour CO concentration at these intersections would
also be below the State AAQS of 20.0 ppm and below the federal AAQS of 35 ppm. The proposed project
would have a less than significant impact on local air quality for CO.
Impact: Create objectionable odors affecting a substantial number of people? Some objectionable
odors may emanate from the operation of diesel - powered construction equipment during the construction
of the proposed project. These odors, however, would be limited to the short-term construction period of
the project and are not expected to be substantial; therefore, objectionable odors associated with the
proposed project would be less than significant. An approximate 0.5 ac dog park is proposed as part of
the proposed project. Use of the park would include a requirement for pet owners to remove pet feces.
Therefore, implementation of the proposed project would not add any long -term odor sources to the
project area and project impacts would be less than significant
Impact: Conflict with any local policies or ordinances protecting biological resources, such as a
tree preservation policy or ordinance. The project includes features including use of native species
(PDF BIO -2), wetland habitat enhancement (PDF BIO -1), and the preservation of open space on site in
the form of a passive park. The goals and policies that apply to the proposed project from the City of
Newport Beach's Natural Resource Element of the General Plan speak to the protection of sensitive and
rare terrestrial resources from urban development, including the protection, maintenance, and
enhancement of Southern California wetlands. Implementation of the proposed project is designed to
comply with the Orange County NCCP /HCP; avoid impacts to sensitive natural plant communities,
sensitive wildlife, and wildlife movements; and avoid direct impact to jurisdictional wetlands. Furthermore,
prescribed mitigation measures would require the presence of an experienced biologist to monitor project
construction and development to ensure that sensitive plant communities designated for preservation and
associated wildlife are protected during project construction activities. Therefore, implementation of the
proposed project would not conflict with any local policies or ordinances protecting biological resources,
and no mitigation is required.

PDF BIO -1: Removal of Invasive Exotic Plants. Invasive exotic plant species (e.g., myoporum,
castor bean, pampas grass) associated with the wetland /riparian habitat shall be removed, and
mulefat and willow cuttings and other appropriate plant species shall be installed.
PDF BIO -2: Native Plants. The landscaping palette to be used on site shall include the use of
native plant species in addition to drought tolerant, ornamental, and turf species. The landscaping
palette shall also prohibit the use of invasive exotic plants (i.e., those plant species rated as `High"
or "Moderate" in the California Invasive Plant Council's [Cat -IPCj Invasive Plant Inventory).
Impact: Rupture of a known earthquake fault, as delineated on the most recent Alquist- Priolo
Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other
substantial evidence of a known fault. As the project site is not located in an Alquist - Priolo Earthquake
Fault Zone and there is no evidence of active faulting on or around the immediate project site, the
potential for ground rupture to affect the proposed project site is considered to be less than
significant, and no mitigation is necessary.
Impact: Seismic - related ground failure, including liquefaction. Potential impacts associated with
seismically induced ground failure and liquefaction would be very low and is considered to be a less than
significant impact, and no mitigation is required.
Impact: Landslides. The potential for on -site landslides is low, and the proposed project would not
expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or
death involving landslides, and no mitigation is required.
Impact: Settlement Potential. The majority of the materials underlying the proposed project site consist
of dense terrace deposits and bedrock, and the site is not located within a potential liquefaction zone.
Therefore, potential impacts related to ground settlement are considered to be less than significant.
Impact: Subsidence. The project does not have an oil, gas, or water pump on site and none are located
in the vicinity of the site and has not been used for the extraction of either resource. Subsidence is
therefore not considered a potential constraint or a potentially significant impact of the project, and no
mitigation is required.
Impact: Result in substantial soil erosion or loss of topsoil. The proposed project would result in a
net increase in storm water runoff; however, the proposed project also incorporates two on -site detention
storage tanks and biofiltration swales to manage increased peak runoff from the site. These detention
basins would be sized to detain the volume of storm water necessary to reduce peak discharge from the
project site. As a result, any increase in peak discharge would be negligible. Therefore, the proposed
project would not result in substantial on -site or downstream erosion, siltation, or flooding, and no
mitigation is required.
Impact: Emit hazardous emissions or handle hazardous or acutely hazardous materials,
substances, or waste within one - quarter mile of an existing or proposed school. The proposed
project would not produce hazardous emissions or handle acutely hazardous materials, substances, or
waste. Furthermore, the proposed project site is not located within 0.25 mi of an existing or proposed
school.
Impact: Be located on a site which is included on a list of hazardous materials sites compiled
pursuant to Government Code Section 65962.5 and, as a result, would create a significant hazard
to the public or the environment. The proposed project site is not included on any hazardous materials
sites pursuant to Government Code Section 65962.5 and will not create a significant hazard to the public
or the environment.
Impact: Impair implementation of or physically interfere with an adopted emergency response
plan or emergency evacuation plan. Access to, from, and on site for emergency vehicles would be

reviewed and approved by the Fire Department prior to project construction. All proposed structures
would be required to comply with all applicable codes and ordinances for emergency vehicle access,
which would ensure adequate access to, from, and on site for emergency vehicles. In addition, traffic
generated by the proposed project would not result in significant delays to emergency vehicles. The
proposed project also includes the construction of an EOC on the proposed project site. Therefore,
because the proposed structures would not block emergency vehicle access to the site or to any adjacent
site, would not result in significant delays to emergency vehicles off site (e.g., due to traffic generation)
and allows the City to upgrade and centralize emergency operations, implementation of the proposed
project would not interfere with adopted emergency response plans and would not result in a significant
impact related to emergency response plans for emergency evacuation routes.
Impact: Result in a cumulatively considerable contribution to a significant hazards and hazardous
materials impact. Based on the distance to the nearest cumulative project and the amount of hazardous
materials use and hazardous waste disposal associated with the proposed project and other hazardous
materials effects from past, present, and reasonably foreseeable projects within the City, the project's
contribution to cumulative impacts would be considered to be less than significant. Because the proposed
project is subject to Federal Aviation Administration (FAA) review and the project would not be permitted if
it would result in a potential hazard, the proposed project would not cumulatively contribute to any
potential airport proximity hazards. Also, based on the distance to the nearest cumulative project and the
amount of hazardous materials use and hazardous waste disposal associated with the proposed project
and other hazardous materials effects from past, present, and reasonably foreseeable projects within the
City, there would be no significant cumulative impacts related to hazards and hazardous materials
associated with the proposed project.
Impacts: The following impacts are discussed together in the DEIR and FEIR; each bullet point
represents a potential environmental impact that is discussed below.
Violate any water quality standards or waste discharge requirements.
• Substantially degrade water quality.
• Result in significant alteration of receiving water quality during or following construction.
• Result in a potential for discharge of storm water pollutants from areas of material storage,
vehicle or equipment fueling, vehicle or equipment maintenance (including washing), waste
handling, hazardous materials handling or storage, delivery areas, loading docks or other
outdoor work areas.
Result in the potential for discharge of storm water to affect the beneficial uses of the
receiving waters.
• Create the potential for significant changes in the flow velocity or volume of storm water
runoff to cause environmental harm.
Construction Impacts. Best management practices (BMPs) consistent with Best Available Technologies/
Best Control Technology (BAT /BCT) are required by the Construction General Permit, Drainage Area
Management Plan (DAMP), and Local Implementation Plan (LIP) to be implemented during the
construction phase of the project. Erosion and sediment transport and transport of other potential
pollutants (e.g., construction material - related pollutants) from the project site during the construction
phase would be reduced or prevented through implementation of BMPs meeting BAT /BCT so as to
prevent or minimize environmental impacts and to ensure that discharges during the construction phase
of the project would not cause or contribute to any exceedance of water quality standards in the receiving
waters. Based upon the factors discussed above and adherence to PDF WQ -1, which requires
compliance with the requirements of the General Construction Permit, and PDF WQ -2, which required
compliance with the De Minimus Permit, potential construction impacts related to erosion, siltation
violation of water quality standards or waste discharge requirements, or degradation of water quality
would be less than significant.
City Hall and Park Development Plan
CEQA Findings of Fact
Page 10
Operation Impacts. The change in land use to a Civic Center Complex, including, parking lots /structure,
driveways, a dog park, and other landscaped areas has the potential to increase the types of pollutants in
runoff or increase pollutant loading to City storm drains and Newport Bay. As specified in PDF WO-3, the
project would implement several Source Control, Site Design, and Treatment Control BMPs to reduce the
discharge of pollutants of concern to the maximum extent practical.
PDF -WQ -1: State General Construction Activity NPDES Permit. Prior to and during
construction, the City of Newport Beach shall comply with the requirements of the National
Pollution Discharge Elimination System (NPDES) General Permit, Waste Discharge
Requirements (WDRs) for Discharges of Storm Water Runoff Associated with Construction
Activities (Order No. 99 08 DWQ, NPDES No. CAS000002) and any subsequent permit as they
relate to construction activities. This shall include submission of a Notice of Intent (NOI) to the
Santa Ana Regional Water Quality Control Board (RWQCB) at least 30 days prior to the start of
construction, preparation and implementation of a Storm Water Pollution Prevention Plan
(SWPPP) and submission of a Notice of Termination (NOT) to the Santa Ana RWQCB upon
completion of construction and stabilization of the site. Prior to construction activities and after the
final design phase and environmental determinations, a construction SWPPP and a Monitoring
and Reporting Program shall be developed for the project. The construction phase SWPPP shall
be designed to identify potential pollutant sources associated with construction activities; identify
non -storm water discharges; and identify, implement, and maintain Best Management Practices
(BMPs) to reduce or eliminate pollutants associated with the construction site.
PDF -WQ -2: Short-Term Groundwater Discharges. Prior to commencement of grading
activities, the City of Newport Beach shall determine whether dewatering of groundwater will be
necessary during project construction and whether dewatering activities will require discharge to
the storm drain system or surface waters. If dewatering activities are required, the City of Newport
Beach shall comply with the requirements of the General National Pollutant Discharge Elimination
System (NPDES) Permit/Waste Discharge Requirements (WDR) for Short-Term Groundwater
Discharges and De Minimus Wastewater Discharges (Order No. R8 -2004 -0021, amended by
order R8- 2006 -0065) or subsequent permit. This will include submission of a Report of Waste
Discharge (ROWD) and Notice of Intent for coverage under the permit to the Santa Ana Regional
Water Quality Control Board (RWQCB) at least 45 days prior to the start of dewatering and
compliance with all applicable provisions in the permit, including water sampling, analysis, and
reporting of dewatering - related discharges.
PDF -WQ3: Site Design, Source Control, and Treatment Best Management Practices. The
City of Newport Beach shall comply with the requirements of the Orange County Drainage Area
Management Plan (DAMP), the City of Newport Beach Local Implementation Plan (LIP), and the
City of Newport Beach Council Policies and Municipal Code, as they relate to hydrology and
water quality. Project- specific Site Design, Source Control, and Treatment Control Best
Management Practices (BMPs) contained in the Final Water Quality Management Plan
(WQMP) shall be incorporated into final design. The BMPs shall be properly designed and
maintained to target pollutants of concern and reduce runoff from the project site. The WQMP
shall include an operations and maintenance plan for the prescribed Treatment Control BMPs to
ensure their long -term performance.
Environmental Impact: Would the project substantially deplete groundwater supplies or interfere
substantially with groundwater recharge such that there would be a net deficit in aquifer volume
or a lowering of the local groundwater table level (e.g., the production rate of preexisting nearby
wells would drop to a level which would not support existing land uses or planned uses for which
permits have been granted)? The proposed project is not located in a groundwater recharge area.
Some groundwater dewatering may be required during construction activities. However, dewatering
activities would be temporary, and the volume of groundwater removed would not be substantial.
City Hall and Park Development Plan
CEQA Findings of Fact
Page 11
Groundwater withdrawal would not be required during operation of the project. Therefore, the proposed
project would not impact existing groundwater supplies.
Impacts: The following impacts are discussed together in the DEIR and FEIR; each bullet point
represents a potential environmental impact that is discussed below.
• Substantially alter the existing drainage pattern of the site or area, including through the
alteration of the course of a stream or river, in a manner which would result in a substantial
erosion or siltation on- or off -site.
• Substantially alter the existing drainage pattern of the site or area, including through the
alteration of the course of a stream or river, or substantially increase the rate or amount of
surface runoff in a manner which would result in flooding on- or off -site.
• Create or contribute runoff water which would exceed the capacity of existing or planned
storm water drainage systems or provide substantial additional sources of polluted runoff.
Create significant increases in erosion of the project site or surrounding areas.
Construction Impacts. During construction activities, the project site would be graded and excavated soil
would be exposed, and there would be an increased potential for soil erosion compared to existing
conditions. Additionally, during a storm event, soil erosion could occur at an accelerated rate. There is
also the potential for construction - related pollutants to be discharged into the City's storm drains during
construction activities of the proposed project. Compliance with the requirements of the General
Construction Permit, including preparation of a SWPPP, would result in less than significant impacts
related to erosion and siltation associated with construction of the proposed project.
Operation Impacts. The proposed project would have a less than significant impact on drainage patterns,
on- or off -site erosion or siltation, drainage volumes and velocities, or flood potential downstream.
Impact: Result in a cumulatively considerable contribution to a significant hydrology and/or water
quality impact. New development and redevelopment can result in increased urban pollutants in dry
weather and storm water runoff from project sites. Regional programs and BMPs such as total maximum
daily load (TMDL) programs, the DAMP /LIP, and the MS4 Permit Program have been designed under an
assumption that the San Diego Creek Watershed will continue the pattern of urbanization. The regional
control measures contemplate cumulative effects of proposed development. Compliance with these
regional programs and the General Construction Permit constitutes compliance with programs intended to
address cumulative hydrological and water quality impacts. Therefore, the project's contribution to
cumulative water quality and hydrology impacts would be less than significant.
Impact: Result in exposure of persons to or generation of noise levels in excess of standards
established in the local general plan or noise ordinance, or applicable standards of other
agencies. Under both future year (2013 and General Plan) Buildout scenarios, project - related traffic
would have no perceptible noise level increases along roadway segments in the project vicinity. The
range of traffic noise level increase is less than the thresholds of increase identified in the City's General
Plan Policy N1.8. Therefore, the traffic noise level increase is not considered to be a significant impact.
The proposed project site would, however, be potentially impacted by traffic noise and mitigation is
required. The proposed project would not result in potentially significant impacts related to stationary
noise sources and no mitigation is required.
Impact: Result in exposure of persons to or generation of excessive groundborne vibration or
groundborne noise levels. Due to the distance from the project site of other existing uses on the east
side of MacArthur Boulevard and on the west side of Avocado Avenue, no significant groundborne
vibration would occur at these nearby land uses during project construction. Similarly, due to the distance
to the nearest residences, groundborne vibration associated with on -site vehicle movement would be
much lower than the vibration impact threshold for frequent events and the vibration impact threshold for
infrequent events suggested by the Federal Transit Administration (FTA).
City Hall and Park Development Plan
CEQA Findings of Fact
Page 12
Impact: Result in a cumulatively considerable contribution to a significant noise impact. Under the
future General Plan Build Out with project scenario, traffic noise levels would increase by 1.5 dBA or less
compared to existing conditions along all roadway segments in the project vicinity; noise levels
attributable to the project under future General Plan Build Out would increase by 0.6 dBA along one
roadway segment and by 0.3 dBA or less along all other roadway segments. A noise level increase of 1.5
dBA in an outside environment is not perceptible to the human ear. In addition, although West Coast
Highway from Newport Boulevard to Riverside Avenue and East Coast Highway from Dover Drive to
Bayside exceed the 75 dBA threshold (refer to City Policy N1.8), neither of these roadway segments have
sensitive uses that would be impacted by an increase in the ambient CNEL produced by the proposed
project. Therefore, the project's cumulative traffic noise contribution is considered less than cumulatively
considerable, and no mitigation is required.
Impact: Induce substantial population growth in an area, either directly (for example, by proposing
new homes and businesses) or indirectly (for example, through extension of roads or other
infrastructure). Due to the availability of housing, available workforce, and relatively small percentage of
population growth represented by the proposed project, the proposed project would result in a less than
significant increase in population in the City and County. In addition, the potential social and economic
changes that may result from the proposed project (i.e., increased employment opportunities and
population growth) would not result in a significant physical change to the environment.
Impact: Result in a cumulatively considerable contribution to a significant housing, population, or
employment impact. The proposed project would not result in substantial employment growth and would
not induce significant population or housing growth, either directly or indirectly. Moreover, due to the
availability of housing, available workforce, and relatively small percentage of growth represented by the
proposed project, the project's contribution to cumulative social and economic changes that may result
from the proposed project (i.e., increased employment opportunities and population growth) would be less
than significant.
Impact: Result in substantial adverse physical impacts associated with the provision of new or
physically altered governmental facilities, or need for new or physically altered governmental
facilities, the construction of which could cause significant environmental impacts, in order to
maintain acceptable service ratios, response times, or other performance objectives for fire
protection. The proposed project would be serviceable within the Newport Beach Fire Department's
(NBFD) current staffing and resources, and the proposed project would not increase response times for
fire and emergency vehicles to the existing City Hall site or the proposed project site. According to Project
Design Feature (PDF) PSU -1, the City would also comply with Title 9 of the Municipal Code (Fire Code),
which requires installation of fire sprinklers and articulates fire flow requirements, access requirements,
placement of hydrants, and other fire protection requirements. Compliance with Title 9 would further
reduce potential impacts related to fire protection services within the City.
PDF PSU -1: Fire Code. The City of Newport Beach (City) shall comply with the requirements of
Title 9 (Fire Code) of the City's Municipal Code including installation of fire sprinklers in all new
buildings. Said sprinklers shall be installed prior to each final building inspection.
Impact: Result in substantial adverse physical impacts associated with the provision of new or
physically altered governmental facilities, or need for new or physically altered governmental
facilities, the construction of which could cause significant environmental impacts, in order to
maintain acceptable service ratios, response times or other performance objectives for police
protection. The proposed project would not substantially increase response times or create a substantial
increase in demand for staff, facilities, equipment, or police services. No mitigation is required.
Impact: Result in substantial adverse physical impacts associated with the provision of new or
physically altered governmental facilities, or need for new or physically altered governmental
facilities, the construction of which could cause significant environmental impacts, in order to

maintain acceptable service ratios, response times or other performance objectives for public
schools. The proposed project would not result in a substantial increase in student enrollment in the
Newport Mesa Unified School District. Therefore, potential impacts related to public schools are less than
significant.
Impact: Result in substantial adverse physical impacts associated with the provision of new or
physically altered governmental facilities, or need for new or physically altered governmental
facilities, the construction of which could cause significant environmental impacts, in order to
maintain acceptable service ratios, response times or other performance objectives for library
services. The proposed project includes an approximate 17,000 sf expansion of the existing Newport
Beach Central Library. The expansion area would provide a reading room, tenant space, media room,
and other ancillary uses. Generation of additional demand for library services resulting from a population
increase generated by the proposed project would be offset through the expansion of the Library and
library services, including the City Hall delivery program. Project impacts related to library services would
be less than significant, and no mitigation is required.
Impact: Result in substantial adverse physical impacts associated with the provision of new or
physically altered governmental facilities, or need for new or physically altered governmental
facilities, the construction of which could cause significant environmental impacts, in order to
maintain acceptable service ratios, response times or other performance objectives for public
transportation. Through existing programs, the City encourages the use of alternative transportation,
including public transportation and use of bicycles. Orange County Transportation Authority (OCTA)
indicated that while more riders would be expected as a result of the proposed project, because existing
routes in the vicinity of the proposed project are operating within capacity any additional ridership
resulting from the proposed project could be accommodated. There are existing bicycle facilities (e.g.,
lanes and paths) in the vicinity of the proposed project. Existing bikeways would be maintained as part of
the proposed project. In addition to maintaining current bike lanes, the City would continue to seek new
opportunities to promote commuter carpooling and transit use, as well as alternative transportation for
City employees and visitors to the Civic Center. Therefore, no significant impacts to public transportation
services are anticipated.
Impact: Exceed wastewater treatment requirements of the applicable wastewater treatment
provider. Orange County Sanitation District (OCSD) would provide treatment of wastewater for the
proposed project. Increased wastewater flows from the proposed project can be accommodated within
the existing design capacity of the Reclamation Plant No. 2. Therefore, the proposed project would not
exceed the wastewater treatment requirements of the Santa Ana RWQCB. Project impacts related to
wastewater treatment requirements are less than significant.
Impact: Require or result in the construction of new water or wastewater treatment or collection
facilities or expansion of existing facilities, the construction of which could cause significant
environmental effects.
Water. The project would not necessitate new or expanded water entitlements, and the City would be
able to accommodate the increased demand for potable water through existing water acquisition
programs and pumping from existing wells (see existing setting, above). The only new water infrastructure
that would be required for project build out would occur on site as part of proposed project construction
(i.e., installation of new water pipes and meters on site).
Wastewater. The proposed project would not require, nor would it result in, the construction of new
wastewater treatment or collection facilities or the expansion of existing facilities other than those facilities
to be constructed on site that could cause significant environmental effects. Project impacts related to the
construction of wastewater treatment or collection facilities and the capacity of the wastewater treatment
provider are less than significant

PDF PSU -4: Water Conservation. The proposed project would also utilize additional water
conservation measures in the proposed Civic Center which may include, but is not limited to:
1. Low -flow faucets
2. Dual -flush water - closets and pint (1/8 gallon per flush) urinals
3. Drip irrigation where practical
4. Project landscaping will include drought - tolerant and native species combined with
ornamental species and turf
5. Cooling tower water use reduction via nonchemical water treatment.
Impact: Require or result in the construction of new storm water drainage facilities or expansion
of existing facilities, the construction of which could cause significant environmental effects.
Under the proposed conditions, there would be a net decrease in peak discharge at four of the discharge
points. At the remaining two discharge points, the increase in peak discharge would be no more than 1
percent or 1 -CFS, or both. The stormdrains have sufficient capacity to absorb the predicted increase and
still operate within the standards of the Orange County Hydrology Manual. Because the decrease and /or
negligible increase in peak discharge would not adversely affect the capacity of downstream networks,
construction or expansion of storm water drainage facilities would not be required.
Impact: Necessitate new or expanded water entitlements. The project would not necessitate new or
expanded water entitlements, and the City would be able to accommodate the increased demand for
potable water through existing water acquisition programs and pumping from existing wells (see existing
setting, above). The only new water infrastructure that would be required for project build out would occur
on site as part of proposed project construction (i.e., installation of new water pipes and meters on site).
Impact: Result in a determination by the wastewater treatment provider which serves or may serve
the project that it has inadequate capacity to serve the project's projected demand in addition to
the provider's existing commitments. The project would not necessitate new or expanded water
entitlements, and the City would be able to accommodate the increased demand for potable water
through existing water acquisition programs and pumping from existing wells (see existing setting,
above). The only new water infrastructure that would be required for project build out would occur on site
as part of proposed project construction (i.e., installation of new water pipes and meters on site).
Impact: Result in substantial adverse physical impacts associated with the provision of new or
physically altered energy transmission facilities, the construction of which could cause significant
environmental impacts, in order to maintain acceptable levels of service.
Electricity. The project incorporates aggressive commitments to reduce and minimize electricity
consumption and avoid wasteful or inefficient consumption of energy. Based on California Energy
Commission (CEC) projections for Southern California Edison's (SCE) service area sufficient
transmission and distribution capacity exists and off -site improvements would not be necessary. Impacts
associated with the proposed project's electricity demand would be less than significant.
Natural Gas. The supply and distribution of natural gas within the area surrounding the proposed project
would not be reduced or inhibited as a result of the proposed project, and levels of service to off -site
users would not be adversely affected. In addition, implementation of PDFs GHG -1, GHG -2, and PSU -2
would ensure that energy conservation efforts are incorporated into the project with the intention of
reducing overall demand. Therefore, impacts related to the provision of natural gas services to the
proposed project would be less than significant.
PDF PSU -2: Electricity and Natural Gas. The proposed project shall meet or exceed all State
Energy Insulation Standards and City of Newport Beach codes in effect at the time of application
for building permits. (Commonly referred to as Title 24, these standards are updated periodically

Exterior shading devices
Proper building orientation
Impact: Be served by a landfill with insufficient permitted capacity to accommodate the project's
solid waste disposal needs. Area landfills have indicated that they have sufficient capacity to
accommodate construction debris from the proposed project site as well as meet the project's operational
solid waste disposal demand. Therefore, the proposed project would not result in any significant impacts
to solid waste landfill capacity in the County of Orange (County).
Impact: Fail to comply with federal, State, and local statutes and regulations related to solid
waste. Orange County Waste & Recycling (OCWR) and the City (refer to PDF PSU -3) comply with all
federal, State, and local statutes and regulations related to solid waste. The proposed project would not
inhibit OCWR's or the City's compliance with the requirements of each of the governing bodies.
PDF PSU -3: Solid Waste. In compliance with State legislation (Assembly Bill [AS] 939), the City
of Newport Beach implements programs to recycle, reduce refuse at the source, and compost
solid waste in order to achieve a 50 percent reduction in solid waste disposed of at landfills. AS
939 also requires that all cities conduct a Solid Waste Generation Study (SWGS) and prepare a
Source Reduction Recycling Element (SRRE). In accordance with AS 939, the City of Newport
Beach submits an annual report to the California Integrated Waste Management Board (CIWMB)
summarizing its progress in diverting solid waste disposal.
Impact: Include a new or retrofitted storm water treatment control Best Management Practice
(BMP), (e.g., water quality treatment basin, constructed treatment wetland), the operation of which
could result in significant environmental effects (e.g., increased vectors and odors). The City would
be responsible for all maintenance activities associated with the storm water Treatment Control BMPs.
BMPs would be inspected periodically by a designated staff member, such as the facilities manager, to
ensure they are functioning properly. Routine and periodic maintenance activities such as debris and
sediment removal would be conducted by the City's landscape maintenance crew. Nonroutine
maintenance such as major reconstruction or replacement would be handled by contractors with
experience in constructing storm water Treatment Control BMPs. Because the BMPs would be designed,
inspected, and maintained to prevent ponding, vectors, and odors, impacts related to operation of storm
water Treatment Control BMPs are considered less than significant
Impact: Result in a cumulatively considerable contribution to a significant public service and
utilities impact. Implementation of the proposed project would not have a cumulatively considerable
impact associated with fire protection, police protection, public schools, library services, public
transportation, water, wastewater, electricity, natural gas or solid waste.
City Hall and Park Development Plan
CEQA Findings of Fad
Page 16
Impact: Increase the use of existing neighborhood and regional parks or other recreational
facilities such that substantial physical deterioration of the facility would occur or be accelerated.
Because the proposed project would add parkland to the City's parkland inventory and would not result in
substantial population growth, which is the determining factor in supplying adequate parks and open
space to residents, the proposed project would not result in increased use of existing parks or
recreational facilities that could accelerate physical deterioration of those facilities. Impacts to existing
recreation facilities would be less than significant, and no mitigation is required.
Impact: Include recreational facilities or require the construction of or expansion of recreational
facilities which might have an adverse physical effect on the environment. Development of the
proposed project, including proposed recreation facilities, could result in adverse physical impacts to the
environment. Construction and operation of the proposed park facilities are expected to result in
significant adverse physical effects on the environment as outlined in the DEIR. Even with implementation
of all feasible mitigation, the proposed project may have significant unavoidable impacts involving
construction air quality and global climate change /greenhouse gas emissions. Because each of these
potential significant impacts and potential significant unavoidable impacts relate to a separate
environmental topic analyzed in the DEIR, and there is no identifiable physical impact to the environment
that is unique to recreation resources, additional mitigation is not required.
Impact: Result in a cumulatively considerable contribution to a significant recreation resources
impact. The proposed project would not result in substantial cumulative population that would result in
increased use and physical deterioration of existing parks. In addition, the proposed project includes the
development of a park and park facilities on the proposed project site that would address any increased
demand for improved park space generated by the new City Hall. The provision of additional park
acreage may reduce use and /or redistribute use of existing parks, resulting in a positive effect on park
demand and park acreage within the City. Therefore, the proposed project would not cumulatively
contribute to impacts associated with parks and recreation facilities. There is not identifiable physical
impact to the environment that is unique to recreation because the potentially significant project and
cumulative impacts relate to separate environmental topics analyzed in the DEIR. No additional
recreation- related mitigation is required to address these potential (i.e., air quality and global climate
change) cumulative impacts.
C. ENVIRONMENTAL EFFECTS WHICH WERE DETERMINED TO BE LESS THAN
SIGNIFICANT WITH MITIGATION
The FEIR identified certain potentially significant effects that could result from the proposed project.
However, the Newport Beach City Council finds for each of the significant or potentially significant
impacts identified in this section, based upon substantial evidence in the record, that changes or
alterations have been required or incorporated into the proposed project that avoid or substantially lessen
the significant effects as identified in the FEIR. As a result, adoption of the mitigation measures set forth
below will reduce the identified significant effects to a less than significant level.
Land Use
Impact: Land Use Compatibility. Although construction noise occurring during hours designated in the
City's Municipal Code is exempt, some residents and users of the Library may find construction noise
irritating. The proposed project would result in a potentially significant short-term land use compatibility
impact related to air quality and noise during construction.
Mitigation Measure 4.1.1: Construction Relations Officer. Prior to commencement of grading
activities, the City of Newport Beach (City) Director of Public Works, or designee, shall designate a
construction relations officer to act as a community liaison concerning on -site construction activity and air

quality emissions- and noise - related matters. The City shall post the name of the contact person and
contact information for complaints in a publicly visible location for the duration of construction activities.
Finding: The mitigation measure is feasible and would avoid or substantially reduce potentially
significant impacts related to land use compatibility to a less than significant level for the reasons set forth
in the FEIR. The City Council hereby directs that this measure be adopted. Implementation of this
measure, which has been required or incorporated into the Project, and included in the Mitigation
Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to a less -
than- significant level.
Traffic and Circulation
Impact: Substantial Increase in Traffic. The addition of project - generated trips is forecast to result in a
significant cumulative impact at the Bayside Drive /Coast Highway intersection for Forecast General Plan
build out with project traffic. In addition, the project construction traffic may cause significant impacts at
the intersections of San Miguel Drive with Avocado Avenue and MacArthur Boulevard, if the project haul
route were to include the use of San Miguel Drive.
Mitigation Measure 4.2.1: Bayside Drive. Prior to issuance of building permits, the City of Newport
Beach (City) Director of Public Works or designee shall identify a future project in the City's Capital
Improvement Program that will include restriping the northbound Bayside Drive approach to the East
Coast Highway intersection from two left -turn lanes and a shared left/through /right lane to two left turns, a
shared left/through lane and a right -turn lane. These required improvements shall be implemented within
1 year of when traffic counts completed on behalf of the City in accordance with the schedule for traffic
counts provided for in the City's Traffic Phasing Ordinance result in the finding that the intersection is
operating at, or over, an Intersection Capacity Utilization (ICU) of 0.90.
Mitigation Measure 4.2.2: Construction Area Traffic Management Plan. Prior to commencement of
grading activities, the City of Newport Beach Director of Public Works or designee shall review and
approve a Construction Area Traffic Management Plan for the proposed project. The Plan shall be
designed by a registered Traffic Engineer and shall address traffic control for any temporary street
closures, detours, or other disruptions to traffic circulation and public transit routes. The Plan shall identify
the routes that construction vehicles shall use to access the site, the hours of construction traffic, traffic
controls and detours, vehicle staging areas, and parking areas for the project. The Plan shall specifically
prohibit the use of San Miguel Drive between MacArthur Boulevard and Newport Center Drive as part of
the haul route for removal of excess dirt from the project site. The Plan shall also require project
contractors to keep all haul routes clean and free of debris including, but not limited to, gravel and dirt.
The City of Newport Beach Director of Public Works or designee shall verify that the Construction
Contractor's Agreement requires the construction contractor to comply with the Construction Area Traffic
Management Plan.
Finding: The mitigation measures are feasible and would avoid or substantially reduce potentially
significant impacts related to traffic and circulation to a less than significant level for the reasons set forth
in the FEIR. The City Council hereby directs that these measures be adopted. Implementation of these
measures, which have been required or incorporated into the Project, and included in the Mitigation
Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to a less -
than- significant level.
Impact: Hazards due to design features. The proposed project could result in a significant impact
related to hazards associated with design features because the minimum sight distances at the project
entrance at Avocado Avenue and Farallon Drive would potentially be inadequate. In addition, the
pedestrian bridge over San Miguel Drive is not of sufficient height, it could obstruct views of intersections
and /or traffic signals.
City Hall and Park Development Plan
CEQA Findings of Fact

PDF TRA -1: Pedestrian Overcrossing. The pedestrian overcrossing linking the northern and central
parcels shall be a minimum of 19.5 feet (ft) above the ground surface of San Miguel Drive.
Mitigation Measure 4.2.3: Sight Distance Analysis. Prior to commencement of grading activities, the
City of Newport Beach Director of Public Works or designee shall verify that a detailed sight distance
analysis for the proposed project driveway along Avocado Avenue has been prepared. The sight distance
analysis shall be prepared according to the City of Newport Beach Sight Distance standards and
guidelines and shall include provisions for dedicated limited use areas (i.e., low- height landscaping) and
on- street parking restrictions (i.e., red curb), if necessary. The sight distance analysis report shall also
verify the required height of the pedestrian bridge (19.5 feet above the ground surface of San Miguel
Drive) as specified in PDF TRA -1. The recommendations of the sight distance analysis shall be
incorporated into final project design to ensure than an unobstructed view of the intersections and traffic
control devices would be provided. The findings of the sight distance analysis shall be included in a report
subject to review and approval by the City of Newport Beach Director of Public Works, or designee.
Finding: The mitigation measure and PDF are feasible and would avoid or substantially reduce
potentially significant impacts related to traffic and circulation to a less than significant level for the
reasons set forth in the FEIR. The City Council hereby directs that this mitigation measure be adopted.
Implementation of this measure, which has been required or incorporated into the Project, and included in
the Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a significant
effect to a less- than - significant level.
Aesthetics
Impact: Creation a new source of substantial light or glare which would adversely affect day or
nighttime views. The proposed project would introduce new light sources that are typical of development
projects. These proposed sources of light would change existing nighttime views from adjacent areas,
including the residences located east of the proposed project site that currently have a view of the project
site. Even with features to reduce lighting effects, the proposed project could result in a substantial
amount of new nighttime light, and mitigation is required.
PDF AES -1: Lighting Controls. The proposed project shall include (1) automated internal shades set to
close at specific times in the City Hall administration building and in the Library expansion area to form
part of the glare control strategy, as well as to assist in the reduction of nighttime light pollution to
neighboring sites; (2) exterior lighting that will be controlled by a Lighting Control Panel with an exterior
photo - control and time clock; (3) internal lighting systems that would auto -dim after standard work hours,
leaving small task lighting for janitorial activities and to light areas where staff may be working late; and
(4) exterior light fixtures that would be the cutoff type and dark sky compliant.
Mitigation Measure 4.3.1: Comprehensive Lighting Plan. Prior to issuance of any building permits, the
City of Newport Beach shall prepare a comprehensive lighting plan for review and approval by the City of
Newport Beach Planning Director or designee. The lighting plan shall be prepared by a qualified engineer
and shall be in compliance with applicable standards of the City of Newport Beach General Plan
Municipal Code. The lighting plan shall address all aspects of lighting, including infrastructure, on -site
driveways, recreation, safety, signage, and promotional lighting, if any. The lighting plan shall include the
following in conjunction with other measures, as determined by the illumination engineer:
a. Exterior on -site lighting shall be shielded and confined within site boundaries.
b. No direct rays or glare are permitted to shine onto public streets or adjacent sites.
C. "Walpak" type fixtures are not permitted.
d. Parking area lighting shall have zero cut -off fixtures, and light standards shall not exceed 24
feet in height.
e. The site shall not be excessively illuminated based on the illumination recommendations of
the Illuminating Engineering Society of North America, or, if in the opinion of the City of
City Halt and Park Development Plan
CEQA Findings of Fact
Page 19
Newport Beach Planning Director, the illumination creates an unacceptable negative impact
on surrounding land uses or environmental resources. The City of Newport Beach Planning
Director or designee may order the dimming of light sources or other remediation upon
finding that the site is excessively illuminated.
Mitigation Measure 4.3.2: Photometric Study. Prior to the issuance of any building permits, a
photometric study shall be prepared in conjunction with a final lighting plan for approval by the City of
Newport Beach Planning Director. The survey shall show that lighting values are 1 footcandle or less at
all property lines.
Mitigation Measure 4.3.3: Lighting Inspection. Prior to issuance of the certificate of occupancy or final
building permits, an evening inspection shall be conducted by the City of Newport Beach Code and Water
Quality Enforcement Division to confirm control of light and glare.
Finding: The mitigation measures and PDF are feasible and would avoid or substantially less potentially
significant impacts related to aesthetics (nighttime lighting) to a less than significant level for the reasons
set forth in the FEIR. The City Council hereby directs that these measures be adopted. Implementation
of these measures, which have been required or incorporated into the Project, and included in the
Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to
a less- than - significant level.
Biological Resources
Impact: Substantial adverse effect, either directly or indirectly through habitat modifications, on
any species identified as a candidate, sensitive, or special status species in local or regional
plans, policies, or regulations, or the CDFG or USFWS. While the proposed project would result in the
loss of native habitat, including some foraging habitat for raptors such as the northern harrier, merlin, and
peregrine falcon, development of the project site is covered by the Central /Coastal Orange County
NCCP /HCP that provides tens of thousands of acres of habitat reserve, including substantial areas
suitable for raptor foraging. Specifically, the conservation of Reserve areas and implementation of
adaptive management methods and other conditions of the Central /Coastal Orange County NCCP /HCP
reduce potential adverse impacts as a result of the loss of native vegetation, much of which is potential
raptor foraging habitat.
Coulter's Saltbush is a special interest plant species not covered in the NCCP /HCP. The population of 18
individuals of Coulter's saltbush located along the eastern edge of the Central Parcel would be completely
eliminated on site as a result of the proposed grading activities. Mitigation is required.
A northern harrier was seen flying over the proposed project site but was not observed nesting. Although
the possibility of northern harriers nesting on site is considered to be unlikely, impacts to northern harriers
would be considered significant if they were found to be actively nesting on site. The City would be
required to comply with the federal Migratory Bird Treaty Act (MBTA), which would reduce potential
impacts to this species to a less than significant level.
Mitigation Measure 4.5.1: Translocation of Coulter's Saltbush Population. Prior to approval of the
grading plan, the City of Newport Beach (City) Director of Planning, or designee, shall verify that a
translocation plan for Coulter's saltbush has been prepared by a qualified, experienced biologist. The plan
shall include the following elements:
Location of one or two suitable receptor site(s), in an area or areas of suitable habitat, with
adequate size to accommodate the existing population, as well as future growth of the
population.
• Procedures for site preparation and translocation of the existing population.
City Hall and Park Development Plan
CEQA Findings of Fact
Page 20
• Preparation for and methods of salvaging and translocating the existing population, including
the recovery of topsoil with existing seed bank. Blocks of topsoil shall be moved intact to the
extent feasible.
• Identification of performance standards, i.e., at least half (nine) of the plants are evident in
any given year following the third year of the monitoring period. This mitigation standard may
be adjusted any time prior to the end of the monitoring period under mutual agreement by the
City and the resource agencies (i.e., United States Fish and Wildlife Service [ USFWS] and
California Department of Fish and Game [CDFG]), particularly if factors beyond human
control limit the ability to establish a viable population of Coulter's saltbush within the 5 -year
monitoring period.
• Maintenance and monitoring provisions (for a minimum of 5 years) to promote and document
the success of the effort.
Measures to be implemented if the translocation effort does not achieve the expected results.
If it becomes apparent that the performance standards cannot be achieved, the City and
resource agencies may agree to extend the monitoring period and /or implement remedial
measures.
The plan shall be prepared in cooperation with representatives from the USFWS and the CDFG. The
project biologist shall supervise and monitor implementation of the plan, which shall be initiated prior to
grading in the affected habitat area. Once the population of Coulter's saltbush on site is transplanted to
the suitable receptor site(s), the project biologist shall monitor the population, in accordance with the plan
provisions, including implementation of any requisite maintenance and /or remedial measures and
documenting the progress in annual reports.
Mitigation Measure 4.5.2: Migratory Bird Treaty Act. In the event that project construction or grading
activities should occur within the active breeding season for birds (i.e., February 15— August 15), a nesting
bird survey shall be conducted by the designated project biologist prior to commencement of construction
activities. If active nesting of birds is observed within 100 feet (ft) of the designated construction area prior
to construction, the construction crew shall establish an appropriate buffer around the active nest. The
designated project biologist shall determine the buffer distance based on the specific nesting bird species
and circumstances involved. Once the designated project biologist verifies that the birds have fledged
from the nest, the buffer may be removed. Prior to commencement of grading activities or issuance of any
building permits, the City of Newport Beach Director of Planning, or designee, shall verify that all project
grading and construction plans include specific documentation regarding the requirements of the
Migratory Bird Treaty Act (MBTA), that preconstruction surveys have been completed and the results
reviewed by staff, and that the appropriate buffers (if needed) are noted on the plans and established in
the field with orange snow fencing.
Finding: The mitigation measures are feasible and would avoid or substantially reduce potentially
significant impacts related to biological resources to a less than significant level for the reasons set forth
in the FEIR. The City Council hereby directs that these measures be adopted. Implementation of these
measures, which have been required or incorporated into the Project, and included in the Mitigation
Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to a less -
than- significant level.
Impact: Substantial adverse effect on any riparian habitat or other sensitive natural community
identified in local or regional plans, policies, regulations or by the CDFG or USFWS.
Implementation of the proposed 20 -acre project would result in the direct loss of 11.68 acres of native
plant communities. The proposed project also includes the preservation of 1.56 acres of native plant
communities and 0.24 acre of landscaped and disturbed plant communities associated with the two
natural drainages (wetlands) on site. Overall, the proposed project would result in the direct loss of
approximately 88 percent of the total native habitat on site. Implementation of the proposed project could
result in significant adverse impacts to native habitat on site. Compliance with the provisions of the NCCP
City Hall and Park Development Plan
CEQA Findings of Fact
Page 21
as identified in Mitigation Measure 4.5.4 reduces project - related impacts to wildlife habitat on site to a less
than significant level.
Mitigation Measure 4.5.4: Orange County Central and Coastal Subregion NCCP /HCP. Prior to
commencement of grading activities, the City of Newport Beach (City) shall comply with the terms and
conditions of the Orange County Central and Coastal Subregion Natural Communities Conservation
Plan /Habitat Conservation Plan (NCCP /HCP) Implementation Agreement and construction minimization
measures identified in the NCCP. The following five minimization measures, as outlined in the NCCP, are
designed to reduce potential impacts associated with native habitat and associated general wildlife and
are applicable to the proposed project site.
To the maximum extent practicable, no grading of coastal sage scrub (CSS) habitat that is occupied
by nesting gnatcatchers shall occur during the breeding season (February 15 -July 15). It is expressly
understood that this provision and the remaining provisions of these `construction- related
minimization measures" are subject to public health and safety considerations. These considerations
include unexpected slope stabilization, erosion control measures, and emergency facility repairs. In
the event of such public health and safety circumstances, landowners or public agencies /utilities shall
provide the United States Fish and Wildlife Service /California Department of Fish and Game
(USFWS /CDFG) with the maximum practicable notice (or such notice as is specified in the
NCCP /HCP) to allow for capture of gnatcatchers, cactus wrens, and any other CSS Identified Species
that are not otherwise flushed and shall carry out the following measures only to the extent as
practicable in the context of the public health and safety considerations.
2. Prior to the commencement of grading operations or other activities involving significant soil
disturbance, all areas of CSS habitat to be avoided under the provisions of the NCCP /HCP shall be
identified with temporary fencing or other markers clearly visible to construction personnel.
Additionally, prior to the commencement of grading operations or other activities involving disturbance
of CSS, a survey shall be conducted to locate gnatcatchers and cactus wrens within 100 feet of the
outer extent of projected soil disturbance activities, and the locations of any such species shall be
clearly marked and identified on the construction /grading plans.
3. A monitoring biologist, acceptable to USFWS /CDFG, shall be on site during any clearing of CSS. The
City of Newport Beach Director of Planning or designee shall advise USFWS /CDFG at least 7
calendar days (and preferably 14 calendar days) prior to the clearing of any habitat occupied by
Identified Species to allow USFWS /CDFG to work with the monitoring biologist in connection with bird
flushing /capture activities. The monitoring biologist shall flush Identified Species (avian or other
mobile Identified Species) from occupied habitat areas immediately prior to brush - clearing and earth -
moving activities. If birds cannot be flushed, they shall be captured in mist nets, if feasible, and
relocated to areas of the site to be protected or to the NCCP /HCP Reserve System. It shall be the
responsibility of the monitoring biologist to assure that Identified bird species will not be directly
impacted by brush- clearing and earth - moving equipment in a manner that also allows for construction
activities on a timely basis.
4. Following the completion of initial grading/earth movement activities, all areas of CSS habitat to be
avoided by construction equipment and personnel shall be marked with temporary fencing or other
appropriate markers clearly visible to construction personnel. No construction access, parking, or
storage of equipment or materials will be permitted within such marked areas.
5. CSS identified in the NCCP /HCP for protection and located within the likely dust drift radius of
construction areas shall be periodically sprayed with water to reduce accumulated dust on the leaves
as recommended by the monitoring biologist.
Finding: The mitigation measure is feasible and would avoid or substantially reduce potentially
significant impacts related to biological resources to a less than significant level for the reasons set forth
in the FEIR. The City Council hereby directs that this measure be adopted. Implementation of this
City Hall and Park Development Plan
CEQA Findings of Fact
Page 22
measure, which has been required or incorporated into the Project, and included in the Mitigation
Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to a less -
than- significant level.
Impact: Substantial adverse effect on 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. The proposed project would include the
construction of three pedestrian footbridges across the jurisdictional drainages on site. These bridges are
proposed to span the drainages and avoid any direct impacts to the United States Army Corps of
Engineers (ACOE) or CDFG jurisdictional areas (subject to verification by the ACOE). There are no
proposed support structures or other portions of the bridges that would be installed within the ACOE or
CDFG jurisdictional limits on site. Grading and construction work could result in incidental, or accidental,
discharge of materials into jurisdictional areas, which would be a significant project impact. Therefore,
implementation of Mitigation Measure 4.5.3 is required to prevent any incidental or accidental discharge
of fill into jurisdictional areas during construction activities. The construction of footbridges across the
jurisdictional drainages would provide shade to the vegetation growing under the proposed bridges.
Therefore, constructing the pedestrian bridges could indirectly impact vegetation under the bridges. The
localized areas of shade corresponding to the location of the proposed pedestrian footbridges, would
have a less than significant impact on vegetation or wildlife, and no mitigation is required. Although this is
a less than significant project impact, CDFG may require a streambed alteration agreement to address
the effects of shading.
Mitigation Measure 4.5.3: Wetland /Riparian Habitat Enhancement. Prior to the commencement of
grading activities associated with the central parcel, the City of Newport Beach (City) Director of Planning,
or designee, shall verify that grading plans require the installation of orange snow fencing along the entire
construction perimeter of the jurisdictional drainages. The City of Newport Beach Director of Planning, or
designee, shall also verify that the City has contracted a qualified, experienced biologist to be present on
site when the orange snow fence is installed to ensure that it is installed at the appropriate location
outside of the United States Army Corps of Engineers (ACOE) and the California Department of Fish and
Game (CDFG) jurisdictional limits. The orange snow fencing shall be maintained and left in place until all
construction activities in the Central Parcel are complete. The biological monitor shall be present during
any grading or vegetation removal activities occurring within 300 feet of the orange snow fencing. Prior to
removal of the orange snow fencing at the completion of construction activities in the central parcel, the
biological monitor shall conduct a final inspection of the area. The biological monitor shall, as necessary,
maintain direct contact with the City representative throughout the construction process.
Finding: The mitigation measure is feasible and would avoid or substantially reduce potentially
significant impacts related to biological resources to a less than significant level for the reasons set forth
in the FEIR. The City Council hereby directs that this measure be adopted. Implementation of this
measure, which has been required or incorporated into the Project, and included in the Mitigation
Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to a less -
than- significant level.
Impact: 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. The proposed project would result in the direct loss of
approximately 88 percent of the total native habitat on site, resulting in a locally significant loss of foraging
habitat for wildlife. Implementation of the proposed project would have a direct, locally significant adverse
effect on wildlife and wildlife habitat on site. Implementation of Mitigation Measure 4.5.4 is expected to
reduce project - related impacts to wildlife and wildlife habitat on site to a less than significant level. As
stated above, compliance with the terms and conditions of the NCCP Implementation Agreement and
construction minimization measures identified in the NCCP Environmental Impact Report/Environmental
Impact Statement (EIR/EIS) serve as suitable mitigation for project- specific and cumulative impacts to
City Hall and Park Development Plan
CEQA Findings of Fact
Page 23
native habitat and associated general wildlife on site. In addition, Mitigation Measure 4.5.2 would reduce
potential construction impacts to nesting birds.
Mitigation Measure 4.5.2 — see above
Mitigation Measure 4.5.4 — see above
Finding: The mitigation measures are feasible and would avoid or substantially reduce potentially
significant impacts related to biological resources to a less than significant level for the reasons set forth
in the FEIR. The City Council hereby directs that these measures be adopted. Implementation of these
measures, which have been required or incorporated into the Project, and included in the Mitigation
Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to a less -
than- significant level.
Impact: Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community
Conservation Plan, or other approved local, regional, or state habitat conservation plan.
Compliance with the terms and conditions of the NCCP Implementation Agreement and construction
minimization measures identified in the NCCP EIR/EIS serve as suitable mitigation for project - specific
and cumulative impacts to native habitat and associated general wildlife on site (see Mitigation Measure
4.5.4). Coulter's saltbush is not a covered species in the NCCP, and identified impacts to Coulter's
saltbush are addressed in Mitigation Measure 4.5.1. Implementation of Mitigation Measure 4.5.4 would
ensure that the proposed project would not conflict with the existing NCCP /HCP. No additional mitigation
is required.
Mitigation Measure 4.5.1 — see above
Mitigation Measure 4.5.4 — see above
Finding: The mitigation measures are feasible and would avoid or substantially reduce potentially
significant impacts related to biological resources to a less than significant level for the reasons set forth
in the FEIR. The City Council hereby directs that these measures be adopted. Implementation of these
measures, which have been required or incorporated into the Project, and included in the Mitigation
Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to a less -
than- significant level.
Impact: Result in a cumulatively considerable contribution to a significant biological resources
impact. Compliance with the terms and conditions of the NCCP Implementation Agreement and
construction minimization measures identified in the NCCP EIR/EIS serve as suitable mitigation for
project - specific and cumulative impacts to native habitat and associated general wildlife on site (see
Mitigation Measure 4.5.4). When viewed in the context of how much native habitat has already been
conserved in Orange County as part of the NCCP /HCP, the quantity of native habitat on site that would
be lost is not cumulatively considerable. Therefore, implementation of the proposed project would not
result in potentially significant adverse cumulative impacts to native habitats and associated wildlife.
Mitigation Measure 4.5.4 — see above
Finding: The mitigation measure is feasible and would avoid or substantially reduce potentially
significant impacts related to biological resources to a less than significant level for the reasons set forth
in the FEIR. The City Council hereby directs that these measures be adopted. Implementation of these
measures, which have been required or incorporated into the Project, and included in the Mitigation
Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to a less -
than- significant level.

Cultural Resources
Impact: Substantial adverse change in the significance of an archaeological resource pursuant to
State CE0A Guidelines Section 15064.5. The proposed project site is considered to be sensitive for
archaeological resources. The project includes walking paths in the vicinity of the known archaeological
sites, grading, and other ground disturbance required for project construction. These project activities
have the potential to disturb or otherwise impact known and unknown archaeological resources.
Mitigation Measure 4.6.1: Archaeological and Native American Monitors. Prior to commencement of
any grading activity on site, the City shall retain an archaeological monitor and a Native American monitor
to be selected by the City after consultation with interested Tribal and Native American representatives.
Both monitors shall be present at the pregrade conference in order to explain the cultural mitigation
measures associated with the project. Both monitors shall be present on site during all ground - disturbing
activities (to implement the project Monitoring Plan) until marine terrace deposits are encountered. Once
marine terrace deposits are encountered, archaeological and Native American monitoring is no longer
necessary, as the marine deposits are several hundred thousand years old, significantly predating human
settlement in this area.
Mitigation Measure 4.6.2: Archaeological Monitoring Plan and Accidental Discovery. Prior to
commencement of any grading activity on site, the City shall prepare a Monitoring Plan. The Monitoring
Plan shall be prepared by a qualified archaeologist and shall be reviewed by the City of Newport Beach
Director of Planning. The Monitoring Plan should include at a minimum: (1) a list of personnel involved in
the monitoring activities; (2) a description of how the monitoring shall occur; (3) a description of frequency
of monitoring (e.g., full -time, part-time, spot checking); (4) a description of what resources may be
encountered; (5) a description of circumstances that would result in the halting of work at the project site
(e.g., what is considered a "significant' archaeological site); (6) a description of procedures for halting
work on site and notification procedures; and (7) a description of monitoring reporting procedures. If any
significant historical resources, archaeological resources, or human remains are found during monitoring,
work should stop within the immediate vicinity (precise area to be determined by the archaeologist in the
field) of the resource until such time as the resource can be evaluated by an archaeologist and any other
appropriate individuals. Project personnel shall not collect or move any archaeological materials or
human remains and associated materials. To the extent feasible, project activities shall avoid these
deposits. Where avoidance is not feasible, the archaeological deposits shall be evaluated for their
eligibility for listing in the California Register of Historic Places. If the deposits are not eligible, avoidance
is not necessary. If the deposits are eligible, adverse effects on the deposits must be avoided, or such
effects must be mitigated. Mitigation can include, but is not necessarily limited to: excavation of the
deposit in accordance with a data recovery plan (see California Code of Regulations Title 4(3) Section
5126.4(b)(3)(C)) and standard archaeological field methods and procedures; laboratory and technical
analyses of recovered archaeological materials; production of a report detailing the methods, findings,
and significance of the archaeological site and associated materials; curation of archaeological materials
at an appropriate facility for future research and /or display; an interpretive display of recovered
archaeological materials at a local school, museum, or library; and public lectures at local schools and/or
historical societies on the findings and significance of the site and recovered archaeological materials.
It shall be the responsibility of the City Department of Public Works to verify that the Monitoring Plan is
implemented during project grading and construction. Upon completion of all monitoring /mitigation
activities, the consulting archaeologist shall submit a monitoring report to the City of Newport Beach
Director of Planning and to the South Central Coastal Information Center summarizing all
monitoring /mitigation activities and confirming that all recommended mitigation measures have been met.
The monitoring report shall be prepared consistent with the guidelines of the Office of Historic
Preservation's Archaeological Resources Management Reports (ARMR): Recommended Contents and
Format. The City of Newport Beach Director of Planning or designee shall be responsible for reviewing
any reports produced by the archaeologist to determine the appropriateness and adequacy of findings
and recommendations.
City Hall and Park Development Plan
CEQA Findings of Fact
Page 25
Mitigation Measure 4.6.3: Archaeological Site Avoidance. Grading and excavation in the vicinity of
existing archaeological sites CA -ORA- 167/1117 and CA -ORA -1461 shall be avoided. To achieve level
surfaces for proposed project paths, clean (culturally sterile) soils shall be used to cap and protect the
sites. Capping shall be conducted consistent with the provisions of Public Resources Code (PRC) Section
21083.2(b)(3 and 4). Prior to commencement of grading activities, the City of Newport Beach Director of
Public Works shall verify that project grading plans show avoidance of existing cultural sites. The Director
of Public Works shall also verify that grading plans show that the known cultural sites shall be capped
with a minimum of 12 inches of culturally sterile soils from a known source prior to commencement of any
grading activity within 25 feet of these sites. The boundaries of the site shall be identified by a qualified
archaeologist to ensure the entire site has been capped. Precise archaeological site information is
protected from public disclosure by State law. The grading plan shall be clearly marked to indicate that
any cultural resources information on those plans is not for public distribution.
Finding: The mitigation measures are feasible and would avoid or substantially reduce potentially
significant impacts related to cultural resources (archeological) to a less than significant level for the
reasons set forth in the FEIR. The City Council hereby directs that these measures be adopted.
Implementation of these measures, which have been required or incorporated into the Project, and
included in the Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a
significant effect to a less- than - significant level.
Impact: Directly or indirectly destroy a unique paleontological resource or site or unique geologic
feature. Sensitive sediments that may contain fossil remains do exist within the project areas, and there
is the potential to encounter paleontological resources during all ground- disturbing activities for the
proposed project.
Mitigation Measure 4.6.4: Paleontological Resources Impact Mitigation Program. Prior to
commencement of any grading activity on site, the Director of Planning, or designee, shall verify that a
paleontologist, who is listed on the County of Orange list of certified paleontologists, has been retained
and will be on site during all rough grading and other significant ground- disturbing activities in
paleontologically sensitive sediments. The sensitive sediments that have been identified within the project
include the Middle Pleistocene marine and terrestrial sediments as well as middle Miocene Monterey
formation sediments. A paleontologist will not be required on site if excavation is only occurring in artificial
fill.
The paleontologist shall prepare a Paleontological Resources Impact Mitigation Program (PRIMP) for the
proposed project. The PRIMP should be consistent with the guidelines of the Society of Vertebrate
Paleontologists (SVP) (1995) and should include but not be limited to the following:
• Attendance at the pregrade conference in order to explain the mitigation measures associated with
the project.
• During construction excavation, a qualified vertebrate paleontological monitor shall initially be present
on a full -time basis whenever excavation will occur within the sediments that have a
High paleontological sensitivity rating and on a spot -check basis in sediments that have a Low
sensitivity rating. Based on the significance of any recovered specimens, the qualified paleontologist
may set up conditions that will allow for monitoring to be scaled back to part-time as the project
progresses. However, if significant fossils begin to be recovered after monitoring has been scaled
back, conditions shall also be specified that would allow increased monitoring as necessary. The
monitor shall be equipped to salvage fossils and /or matrix samples as they are unearthed in order to
avoid construction delays. The monitor shall be empowered to temporarily halt or divert equipment in
the area of the find in order to allow removal of abundant or large specimens.
• The underlying sediments may contain abundant fossil remains that can only be recovered
by a screening and picking matrix; therefore, these sediments shall be occasionally be spot- screened
through one - eighth to one - twentieth -inch mesh screens to determine whether microfossils exist. If
City Hall and Park Development Plan
CEQA Findings of Fact
Page 26
microfossils are encountered, additional sediment samples (up to 6,000 pounds) shall be collected
and processed through one - twentieth -inch mesh screens to recover additional fossils. Processing of
large bulk samples is best accomplished at a designated location within the project that will
be accessible throughout the project duration but will also be away from any proposed cut or fill
areas. Processing is usually completed concurrently with construction, with the intent to have all
processing completed before, or just after, project completion. A small corner of a staging or
equipment parking area is an ideal location. If water is not available, the location should
be accessible for a water truck to occasionally fill containers with water.
• Preparation of recovered specimens to a point of identification and permanent preservation. This
includes the washing and picking of mass samples to recover small invertebrate and vertebrate
fossils and the removal of surplus sediment from around larger specimens to reduce the volume of
storage for the repository and the storage cost for the developer.
• Identification and curation of specimens into a museum repository with permanent, retrievable
storage, such as the Natural History Museum of Los Angeles County (LRCM).
Preparation of a report of findings with an appended, itemized inventory of specimens. When submitted to
the City of Newport Beach Director of Planning or designee, the report and inventory would signify
completion of the program to mitigate impacts to paleontological resources.
Finding: The mitigation measure is feasible and would avoid or substantially reduce potentially
significant impacts related to cultural resources (paleontological) to a less than significant level for the
reasons set forth in the FEIR. The City Council hereby directs that this measure be adopted.
Implementation of this measure, which has been required or incorporated into the Project, and included in
the Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a significant
effect to a less- than - significant level.
Impact: Disturb any human remains, including those interred outside of formal cemeteries. The
proposed project site is considered to be sensitive for archaeological remains and was the site of a
human burial that was removed and reburied off site. Although no additional human remains are known to
be on site or are anticipated to be discovered, precautionary mitigation is required.
Mitigation Measure 4.6.5: Human Remains. Consistent with the requirements of California Code of
Regulations (CCR) Section 15064.5(e), if human remains are encountered, work within 25 feet of the
discovery shall be redirected and the County Coroner notified immediately. State Health and Safety Code
Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a
determination of origin and disposition pursuant to Public Resources Code Section 5097.98. If the
remains are determined to be Native American, the County Coroner shall notify the Native American
Heritage Commission (NAHC), which will determine and notify a most likely descendant (MILD). With the
permission of the City of Newport Beach, the MILD may inspect the site of the discovery. The MILD shall
complete the inspection within 48 hours of notification by the NAHC. The MILD may recommend scientific
removal and nondestructive analysis of human remains and items associated with Native American
burials. Consistent with CCR Section 15064.5(d), if the remains are determined to be Native American
and an MLD is notified, the City of Newport Beach shall consult with the MILD as identified by the NAHC
to develop an agreement for the treatment and disposition of the remains.
Upon completion of the assessment, the consulting archaeologist shall prepare a report documenting the
methods and results and provide recommendations regarding the treatment of the human remains and
any associated cultural materials, as appropriate, and in coordination with the recommendations of the
MILD. The report should be submitted to the City of Newport Beach Director of Planning and the South
Central Coastal Information Center. The City of Newport Beach Director of Planning, or designee, shall
be responsible for reviewing any reports produced by the archaeologist to determine the appropriateness
and adequacy of findings and recommendations.

Finding: The mitigation measure is feasible and would avoid or substantially reduce potentially
significant impacts related to cultural resources (disturbance of human remains) to a less than significant
level for the reasons set forth in the FEIR. The City Council hereby directs that this measure be adopted.
Implementation of this measure, which has been required or incorporated into the Project, and included in
the Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a significant
effect to a less- than - significant level.
Impact: Result in a cumulatively considerable contribution to a significant cultural resources
impact. Mitigation Measures 4.6.1 through 4.6.5 would be implemented to reduce potential project
impacts by ensuring avoidance, evaluation, and, as applicable, scientific recovery and study of any
resources encountered. Therefore, with implementation of Mitigation Measures 4.6.1 through 4.6.5, the
project's contribution to the cumulative destruction of known and unknown cultural resources throughout
the City would be reduced to below a level of significance.
Mitigation Measure 4.6.1 — see above
Mitigation Measure 4.6.2 — see above
Mitigation Measure 4.6.3 — see above
Mitigation Measure 4.6.4 — see above
Mitigation Measure 4.6.5 — see above
Finding: The mitigation measures are feasible and would avoid or substantially reduce potentially
significant impacts related to cultural resources (cumulative) to a less than significant level for the reasons
set forth in the FEIR. The City Council hereby directs that these measures be adopted. Implementation
of these measures, which have been required or incorporated into the Project, and included in the
Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to
a less- than - significant level.
Geology and Soils
Impact: Strong seismic ground shaking. As with all of Southern California, the project site is subject to
strong ground motion resulting from earthquakes on nearby faults. Strong seismic ground shaking
generated by seismic activity is considered a potentially significant impact that may affect the proposed
project.
Mitigation Measure 4.7.1: Incorporation of and compliance with the recommendations in the
Geotechnical Study. All grading operations and construction shall be conducted in conformance with the
recommendations included in the geotechnical report on the proposed project site that has been prepared
by Leighton Consulting, Inc. titled Geotechnical Study for the Proposed City Hall and Park Development
Plan for the Environmental Impact Report (EIR), Newport Beach, California (July 2009) (included in
Appendix K of the DEIR). Design, grading, and construction shall be performed in accordance with the
requirements of the City of Newport Beach Building Code and the California Building Code
(CBC) applicable at the time of grading, appropriate local grading regulations, and the recommendations
of the project geotechnical consultant as summarized in a final written report, subject to review by the
Director of the City of Newport Beach Building Department or designee prior to commencement of
grading activities.
Recommendations in the Geotechnical Study for the Proposed City Hall and Park Development Plan for
the Environmental Impact Report (EIR), Newport Beach, California are summarized below.
1. Site Grading. The subgrade below the planned foundations for buildings and improvements planned
in the area of the Library expansion shall be overexcavated in order to provide uniform support for the
buildings. Additional remedial grading shall be required to develop relatively uniform support
City Hall and Park Development Plan
CEQA Findings of Fact
Page 28
characteristics and reduce the potential for postconstruction swell and distortions to the building in
areas where claystone is exposed.
2. Shoring. Shoring shall be required during excavation for the retaining wall proposed along MacArthur
Boulevard due to the anticipated space constraint for slope lay back and adverse bedrock structure.
Design parameters of the temporary shoring and retaining wall shall be based on the bedrock strike
and dip and the final configuration of the wall. In addition, the retaining wall shall be designed to
include possible geologic surcharge from the bedrock. Shoring systems feasible for the site are
expected to include cantilever shoring such as soldier piles and lagging in conjunction with tiebacks in
areas when the depth of excavation exceeds 10 to 15 feet (ft).
3. Dewatering. If groundwater or perched water is encountered during project grading and construction,
dewatering may be necessary. Methods of dewatering shall be submitted by the contractor and
reviewed and approved by the geotechnical consultant and City Building Official prior to
commencement of grading activities.
4. Subsurface Drainage. Groundwater is not expected to be a project constraint. In the unlikely event
groundwater is encountered during construction and is at a depth that would impact project structures
(postconstruction), the subterranean slabs shall be designed to resist hydrostatic uplift, or a
permanent subfloor drainage system shall be included in the design of the slab. The design of
subterranean slabs shall be reviewed and approved by the City Building Official prior to issuance of
building permits.
5. Temporary Excavations. All temporary excavations shall be treated in accordance with the State of
California version of Occupational Safety and Health Administration (OSHA) excavation regulations,
Construction Safety Orders for Excavation General Requirements. The sides of excavations shall be
shored or sloped in accordance with OSHA regulations. OSHA allows the sides of unbraced
excavations, up to a maximum height of 20 ft, to be cut to a 3/4H:1 V (horizontal:vertical) slope for Type
A soils, 1H:1V for Type B soils, and 1.5H:1V for Type C soils. The on -site soils (Terrace
Deposits) within the proposed excavation depths generally conform to OSHA Soil Type B. The
formational bedrock may be classified as Soil Type A but will require careful evaluation by the project
Certified Engineering Geologist. The Type A classification is not recommended where adverse (out -
of- slope) bedding orientations exist, and special site - specific design parameters will be required in
those areas. Heavy construction loads, such as those resulting from stockpiles and heavy machinery,
shall be kept a minimum distance equivalent to the excavation height or 5 ft, whichever is greater,
from the excavation unless the excavation is shored and these surcharges are considered in the
design of the shoring system.
6. Spread Footing Foundations. Upon completion of the grading (cutting) required to establish the
proposed building pad elevations, the proposed structures may be supported by a spread footing
foundation system. Bearing capacities shall be dependent on the final foundation elevation and
structural loadings of the buildings and shall be reviewed by the geotechnical consultant prior to
implementation.
7. Slab on Grade. At -grade floor slabs of the proposed structures may be designed and constructed as
a slab -on -grade supported directly on properly compacted fill or competent bedrock. If a bedrock
artificial fill transition is encountered, the planned subgrade elevation shall be overexcavated at least
3 ft and replaced with properly compacted fill. The structural engineer shall design the slab and
determine the required thickness and reinforcement based on structural load requirements.
8. Retaining Walls. The proposed development is expected to require various types of earth - retaining
structures: free - standing cantilever retaining walls; temporary shoring; and belowgrade walls for
several of the proposed structures. In general, free - standing retaining structures planned at the site
shall be backfilled with granular, very low expansive soil and be constructed with a backdrain.
9. Geotechnical Review and Future Testing. Additional site testing and final design evaluation shall be
conducted by the project geotechnical consultant to refine and enhance these recommendations.
Grading plan review shall also be conducted by the project geotechnical consultant and the Director
of the City of Newport Beach Building Department or designee prior to the start of grading to verify
City Hall and Park Development Plan
CEQA Findings of Fact
Page 29
that the recommendations developed during the geotechnical design evaluation have been
appropriately incorporated into the project plans. Final design shall be based on testing and analyses
of the near - surface soils following the completion of grading. Design, grading, and construction shall
be conducted in accordance with the specifications of the project geotechnical consultant as
summarized in a final report based on the CBC applicable at the time of grading and building and the
City of Newport Beach Building Code. On -site inspection during grading shall be conducted by the
project geotechnical consultant and the City Building Official to ensure compliance with geotechnical
specifications as incorporated into project plans
Mitigation Measure 4.7.2: California Building Code Compliance and Seismic Standards. Structures
and retaining walls shall be designed in accordance with the seismic parameters presented in the
geotechnical study (Leighton, 2009; Appendix K) and applicable sections of Section 1613 of the 2007
California Building Code (CBC). Prior to issuance of building permits for planned structures, the project
soils engineer and the Director of the City of Newport Beach Department of Building, or designee, shall
review building plans to verify that structural design conforms to the recommendations of the geotechnical
study and the City of Newport Beach Building Code.
Finding: The mitigation measures are feasible and would avoid or substantially reduce potentially
significant impacts related to geology and soils (seismic ground shaking) to a less than significant level for
the reasons set forth in the FEIR. The City Council hereby directs that these measures be adopted.
Implementation of these measures, which have been required or incorporated into the Project, and
included in the Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a
significant effect to a less- than - significant level.
Impact: Slope Stability. Due to the topography of the project site and the design of the proposed project,
grading would entail significant cut - and -fill slopes, and construction of retaining walls would be necessary
in some areas. Unstable cut - and -fill slopes and an adverse bedrock structure could create significant
short-term and long -term hazards.
Mitigation Measure 4.7.1 — see above
Finding: The mitigation measure is feasible and would avoid or substantially reduce potentially
significant impacts related to geology and soils (slope stability) to a less than significant level for the
reasons set forth in the FEIR. The City Council hereby directs that this measure be adopted.
Implementation of this measure, which has been required or incorporated into the Project, and included in
the Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a significant
effect to a less- than - significant level.
Impact: Corrosive Soils. Laboratory testing indicates that on -site soils are not corrosive to concrete but
are severely corrosive to ferrous metals.
Mitigation Measure 4.7.3: Corrosive Soils. Prior to issuance of a building permit, the Director of the City
of Newport Beach (City) Building Department or designee shall verify that the City has retained the
services of a licensed corrosion engineer to provide detailed corrosion protection measures. Where steel
may come in contact with on -site soils, project construction shall include the use of steel that is protected
against corrosion. Corrosion protection may include, but is not limited to, sacrificial metal, the use of
protective coatings, and /or cathodic protection. Additional site testing and final design evaluation
regarding the possible presence of significant volumes of corrosive soils on site shall be performed by the
project geotechnical consultant to refine and enhance these recommendations. On -site inspection during
grading shall be conducted by the project geotechnical consultant and City Building Official to ensure
compliance with geotechnical specifications as incorporated into project plans.

Finding: The mitigation measure is feasible and would avoid or substantially reduce potentially
significant impacts related to geology and soils (corrosive soils) to a less than significant level for the
reasons set forth in the FEIR. The City Council hereby directs that this measure be adopted.
Implementation of this measure, which has been required or incorporated into the Project, and included in
the Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a significant
effect to a less- than - significant level.
Impact: Expansive Soil. Based on the laboratory test results, the on -site soils have an Expansion Index
ranging from 0 to 29, indicating a very low to low expansion potential in accordance with Table 18 -1 -B of
the CBC. However, bedrock on site includes strata of claystone that may be potentially expansive. The
potential for expansive soils in areas proposed for construction would be considered a potentially
significant impact.
Mitigation Measure 4.7.4: Expansive Soils. Prior to issuance of building permits, the Director of the City
of Newport Beach (City) Building Department or designee shall verify that building plans require additional
expansion index tests if bedrock claystone is encountered at the planned subgrade elevation or during
other grading activities. If expansion index tests determine that expansive soils are present on the
proposed project site, mitigation may include, but is not limited to, additional remedial grading,
premoistening of soils, use of nonexpansive material, post- tensioned slabs, construction of nonexpansive
building pads, or use of caisson foundations. During construction, the project soils engineer shall verify
that expansive soil mitigation measures are implemented, and the City Building Official shall make site
inspections to ensure compliance with approved measures.
Finding: The mitigation measure is feasible and would avoid or substantially reduce potentially
significant impacts related to geology and soils (expansive soils) to a less than significant level for the
reasons set forth in the FEIR. The City Council hereby directs that this measure be adopted.
Implementation of this measure, which has been required or incorporated into the Project, and included in
the Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a significant
effect to a less- than - significant level.
Hazards and Hazardous Materials
Impacts: The following impacts are discussed together in the DEIR and FEIR; each bullet point
represents a potential environmental impact that is discussed below.
Create a significant hazard to the public or the environment through the routine transport,
use, or disposal of hazardous materials.
Create a significant hazard to the public or the environment through reasonably foreseeable
upset and accident conditions involving the release of hazardous materials into the
environment.
Construction Impacts. Project construction would involve the routine use of hazardous materials
such as fuels, paints, and solvents. Project construction may result in the release of asbestos -
containing building materials (ACMs), lead -based paints (LBPs), and polychlorinated biphenyl (PCBs)
associated with demolition activities and utility relocations.
Operation Impacts. Project operation would involve the use of potentially hazardous materials (e.g.,
solvents, cleaning agents, paints, pesticides) typical of government office building parking, structures,
parks, and library facilities that, when used correctly, would not result in a significant hazard to
employees. Operation of the proposed project would not produce hazardous emissions or handle
acutely hazardous materials, substances, or waste. Fuel would be stored on site for a backup
generator in a generator sub -base fuel storage tank subject to fire department guidelines.
City Hall and Park Development Plan
CEQA Findings of Fact

Mitigation Measure 4.9.1: Contingency Plan. Prior to commencement of grading activities, the City of
Newport Beach Fire Chief or designee shall review and approve a contingency plan that addresses the
potential to encounter on -site unknown hazards or hazardous substances during construction activities.
The plan shall indicate that if construction workers encounter underground tanks, gases, odors,
uncontained spills, or other unidentified substances, the contractor shall stop work, cordon off the
affected area, and notify the Orange County Health Care Agency ( OCHCA). The OCHCA responder shall
determine the next steps regarding possible site evacuation, sampling, and disposal of the substance
consistent with local, State, and federal regulations.
Mitigation Measure 4.9.2: Predemolition Surveys. Prior to commencement of demolition activities, the
Director of the City of Newport Beach (City) Building Department shall verify that predemolition surveys
for asbestos - containing materials (ACMs) and lead -based paints (LBPs) (including sampling and analysis
of all suspected building materials) and inspections for polychlorinated biphenyl (PCB) - containing
electrical fixtures shall be performed. All inspections, surveys, and analyses shall be performed by
appropriately licensed and qualified individuals in accordance with applicable regulations (i.e.: American
Society for Testing and Materials (ASTM) E 1527 -05, and 40 Code of Federal Regulations (CFR),
Subchapter R, Toxic Substances Control Act [TSCA], Part 716). If the predemolition surveys do not find
ACMs, LBPs, or PCB - containing electrical fixtures, the inspectors shall provide documentation of the
inspection and its results to the City of Newport Beach Building Department to confirm that no further
abatement actions are required. If the predemolition surveys find evidence of ACMs, LBPs, or PCB -
containing electrical fixtures, all such materials shall be removed, handled, and properly disposed of by
appropriately licensed contractors according to all applicable regulations during demolition of structures
(40 CFR, Subchapter R, TSCA, Parts 745, 761, and 763). Air monitoring shall be completed by
appropriately licensed and qualified individuals in accordance with applicable regulations both to ensure
adherence to applicable regulations (e.g., South Coast Air Quality Management District [SCAQMD]) and
to provide safety to workers and the adjacent community. The City shall provide documentation (e.g., all
required waste manifests, sampling, and air monitoring analytical results) to the County of Orange Health
Care Agency showing that abatement of any ACMs, LBPs, or PCB - containing electrical fixtures identified
in these structures has been completed in full compliance with all applicable regulations and approved by
the appropriate regulatory agency(ies) (40 CFR, Subchapter R, TSCA, Parts 716, 745, 761, 763, and 795
and California Code of Regulations [CCR] Title 8, Article 2.6). An Operating & Maintenance Plan
(O &M) shall be prepared for any ACM, LBP, or PCB - containing fixtures to remain in place and will be
reviewed and approved by the County of Orange Health Care Agency.
Mitigation Measure 4.9.3: Generator Sub -Base Fuel Storage Tank. Prior to issuance of building
permits, the Director of the City of Newport Beach Building Department or designee shall review
installation plans for the generator sub -base fuel storage tank. The plans shall include the design, details,
and specifications pertaining to the following:
1. Quantities and types of liquids to be stored
2. Distances from tanks and dispensers to property lines, buildings, and other exposures
3. Vehicle access
4. Fire appliance
5. Vehicle impact protection
6. Protected tanks and their supports
7. Methods of storage and dispensing
8. Overfill prevention, spill containment, vents, vapor recovery dispensers, and other equipment and
accessories

Finding: The mitigation measures are feasible and would avoid or substantially reduce potentially
significant impacts related to hazards and hazardous materials (routine transport, use, or disposal of
hazardous materials) to a less than significant level for the reasons set forth in the FEIR. The City
Council hereby directs that these measures be adopted. Implementation of these measures, which have
been required or incorporated into the Project, and included in the Mitigation Monitoring and Reporting
Program, will substantially lessen the severity of a significant effect to a less- than - significant level.
Impact: Result in a safety hazard for people residing or working in a project area located within an
airport land use plan or, where such a plan has not been adopted, within two miles of a public
airport or public use airport. A portion of proposed project site is located within the AELUP and the
20,000 ft Federal Aviation Regulations (FAR) Part 77 Notification Area for JWA. Although there are no
permanent structures proposed for this parcel, the Federal Aviation Administration (FAA) is requiring the
FAR Part 77 review to consider trees or any other improvement that achieves some height.
Mitigation Measure 4.9.4: Determination of No Hazards. The City of Newport Beach (City) shall file a
Notice of Proposed Construction or Alteration (Form 7460 -1) with the Federal Aviation Administration
(FAA) in accordance with Federal Aviation Regulation (FAR) Part 77. The Director of Planning, or
designer, shall verify that the City has received a Determination of No Hazard to Air Navigation prior to
the issuance of building permits for the northern parcel.
Finding: The mitigation measure is feasible and would avoid or substantially reduce potentially
significant impacts related to hazards and hazardous materials (location near a public use airport) to a
less than significant level for the reasons set forth in the FEIR. The City Council hereby directs that this
measure be adopted. Implementation of this measure, which has been required or incorporated into the
Project, and included in the Mitigation Monitoring and Reporting Program, will substantially lessen the
severity of a significant effect to a less- than - significant level.
Noise
Impacts: The following impacts are discussed together in the DEIR and FEIR; each bullet point
represents a potential environmental impact that is discussed below.
• Result in exposure of persons to or generation of noise levels in excess of standards
established in the local general plan or noise ordinance, or applicable standards of other
agencies.
• A substantial permanent increase in ambient noise levels in the project vicinity above levels
existing without the project.
• A substantial temporary or periodic increase in ambient noise levels in the project vicinity
above levels existing without the project.
Two types of short-term noise impacts could occur during construction of the proposed project: (1) traffic
noise associated with construction crew commutes and the transport of construction equipment and
materials to the site; and (2) noise generated during excavation, grading, and erection of buildings on the
project site. Short-term construction- related impacts associated with worker commute, equipment
transport to the project site, and export of excavated materials would be less than significant, and no
mitigation would be required. Construction - related noise impacts from the proposed project would be
potentially significant due to the length of the construction period (24 -30 months) and level of noise from
the combination of construction activities (up to 80 dBA maximum instantaneous noise level [LR,,J).
Mitigation Measure 4.11.1: Construction Noise. Prior to commencement of grading activities or
issuance of building permits, the Director of the City of Newport Beach Planning Department, or
designee, shall verify that the following notes appear on grading and construction plans:
City Hall and Park Development Plan
CEQA Findings of Fact
Page 33
1. During all project site excavation and grading, the project contractors shall equip all construction
equipment, fixed or mobile, with properly operating and maintained mufflers consistent with
manufacturers' standards.
2. The project contractor shall place all stationary construction equipment so that emitted noise is
directed away from sensitive receptors nearest the project site.
3. The construction contractor shall locate equipment staging in areas that will create the greatest
distance between construction - related noise sources and noise - sensitive receptors nearest the
project site during all project construction.
4. The construction contractor shall limit all construction - related activities that would result in high
noise levels to between the hours of 7:00 a.m. and 6:00 p.m., Monday through Friday, and
between the hours of 8:00 a.m. and 6:00 p.m. on Saturdays. No construction would occur outside
of these hours or on Sundays and federal holidays.
Mitigation Measure 4.11.2: Ventilation Requirements. Prior to the issuance of building permits,
documentation shall be provided to the Director of the City of Newport Beach Building Department, or
designee, demonstrating that project buildings meet ventilation standards required by the California
Building Code (CBC) with the windows closed. It is likely that a form of mechanical ventilation, such as an
air - conditioning system, will be required as part of the project design for the City Hall buildings and Library
expansion.
Mitigation Measure 4.11.3: Park Uses. Prior to the issuance of building permits, the Director of the City
of Newport Beach Planning Department, or designee, shall review construction plans and verify that all
potential sensitive uses proposed within the park areas, such as picnic tables, shall be located outside the
70 A- weighted decibels (dBA) Community Noise Equivalent Level (CNEL) impact zone from MacArthur
Boulevard, which would extend to 167 feet (ft) from the roadway centerline north of San Miguel Drive and
to 140 ft from the roadway centerline south of San Miguel Drive.
Finding: The mitigation measures are feasible and would avoid or substantially reduce potentially
significant impacts related to noise (construction noise) to a less than significant level for the reasons set
forth in the FEIR. The City Council hereby directs that these measures be adopted. Implementation of
these measures, which have been required or incorporated into the Project, and included in the Mitigation
Monitoring and Reporting Program, will substantially lessen the severity of a significant effect to a less -
than- significant level.
D. ENVIRONMENTAL EFFECTS SIGNIFICANT EFFECTS THAT CANNOT BE MITIGATED TO A
LESS THAN SIGNIFICANT LEVEL
The following summary describes the unavoidable adverse impacts of the proposed project where either
mitigation measures were found to be infeasible, or mitigation would lessen impacts but not to a less than
significant level. The following adverse impacts would remain significant and unavoidable:
1. Construction Air Quality (Short-Term Project and Short-Term Cumulative)
Impact: Construction emissions from the project would exceed the South Coast Air Quality Management
District (SCAQMD) daily emissions thresholds for nitrous oxide (NOx) and reactive organic compounds
(ROC), and resulting concentrations of particulate matter less than 10 microns in diameter (PM,o) that
would exceed the local significance threshold (LST) threshold. Mitigation measures would be required to
reduce NOx, ROC, and PM10 emissions; however, even with implementation of all available mitigation
measures, project impacts related to construction emissions would remain significant adverse and
unavoidable.
Mitigation Measure 4.4.1: SCAQMD Rules 402 and 403. The City of Newport Beach shall ensure that
the project complies with South Coast Air Quality Management District (SCAQMD) Rules 402 and 403 to
assist in reducing short-term air pollutant emissions. Rule 403 requires that fugitive dust be controlled
City Hall and Park Development Plan
CEQA Findings of Fad
Page 34
with best available control measures so that the presence of such dust does not remain visible in the
atmosphere beyond the property line of the emission source. Rule 402 requires implementation of dust
suppression techniques to prevent fugitive dust from creating a nuisance off site. Applicable dust
suppression techniques from Rule 403 are summarized below. Prior to commencement of grading
activities, the Director of the City of Newport Beach Planning Department or designee shall ensure that
notes are included on grading and construction plans and referenced in the construction contractor's
agreement that the construction contractor shall be responsible for compliance with Rules 402 and 403.
The applicable Rule 403 measures are as follows:
1. Apply nontoxic chemical soil stabilizers according to manufacturers' specifications to all inactive
construction areas (previously graded areas inactive for 10 days or more).
2. Water active sites at least twice daily. (Locations where grading is to occur will be thoroughly
watered prior to earthmoving.)
3. All trucks hauling dirt, sand, soil, or other loose materials are to be covered or should maintain at
least 2 feet (ft) of freeboard in accordance with the requirements of California Vehicle Code
(CVC) Section 23114 (freeboard means vertical space between the top of the load and top of the
trailer).
4. Pave construction access roads at least 100 ft onto the site from main road.
5. Traffic speeds on all unpaved roads shall be reduced to 15 miles per hour (mph) or less.
Mitigation Measure 4.4.2: Dust Suppression. Prior to commencement of grading activities, the Director
of the City of Newport Beach Planning Department or designee shall ensure that notes are included on
construction and grading plans and referenced in the contractor's agreement that requires use of dust
suppression measures in the South Coast Air Quality Management District (SCAQMD) California
Environmental Quality Act (CEQA) Air Quality Handbook during project grading and construction. The
construction contractor shall be responsible for the implementation of the following dust suppression
measures:
1. Revegetate disturbed areas as soon as possible.
2. Increase active site watering to three times daily.
3. All excavating and grading operations shall be suspended when wind speeds (as instantaneous
gusts) exceed 25 miles per hour (mph).
4. When visible soil materials are carried to adjacent streets, those streets shall be swept once per
day to the extent necessary to remove the visible soil material (recommend water sweepers with
reclaimed water).
5. Install wheel washers where vehicles enter and exit unpaved roads onto paved roads, or wash
trucks and any equipment leaving the site each trip.
6. All on -site roads shall be paved as soon as feasible, watered periodically, or chemically
stabilized.
7. The area disturbed by clearing, grading, earthmoving, or excavation operations shall be
minimized at all times.
Mitigation Measure 4.4.3: Construction Equipment. Prior to commencement of grading activities, the
Director of the City of Newport Beach Public Works Department or designee shall ensure that
construction documents require the Construction Contractor to select the construction equipment used on
site based on low- emission factors and high- energy efficiency. Prior to commencement of grading
activities, the Director of the City of Newport Beach Public Works Department, or designee, shall also
verify that construction contracts include a statement that all construction equipment will be tuned and
maintained in accordance with the manufacturer's specifications.
Mitigation Measure 4.4.4: Electric or Alternative Fuel- Powered Equipment. Prior to issuance of a
Notice to Proceed, the Director of the City of Newport Beach Public Works Department or designee shall
verify that construction contracts and /or grading plans include a statement that the Construction
Contractor shall utilize electric or alternative -fuel powered equipment in lieu of gasoline or diesel powered
engines where feasible.

Mitigation Measure 4.4.5: Equipment Shut Off and Smog Season Hours. Prior to issuance of a Notice
to Proceed, the Director of the City of Newport Beach Public Works Department or designee shall verify
that construction contracts and /or grading plans include a statement that work crews will shut off
equipment when not in use. During smog season (May through October), the overall length of the
construction period will be extended to minimize the occurrence of vehicles and equipment operating at
the same time and thereby decreasing the size of the area prepared each day.
Mitigation Measure 4.4.6: Traffic Obstruction Minimization. Prior to issuance of a Notice to Proceed,
the Director of the City of Newport Beach Public Works Department shall verify that construction contracts
and /or grading plans include a statement that construction trucks, to the extent feasible, shall avoid using
the streets during peak -hour traffic; if necessary, a flagperson shall be retained to maintain safety
adjacent to existing roadways.
Mitigation Measure 4.4.7: Ridesharing and Transit Incentives. Prior to issuance of a Notice to
Proceed, the Director of the City of Newport Beach Public Works Department shall verify that construction
contracts and /or grading plans include a statement that the Construction Contractor shall support and
encourage ridesharing and transit incentives for the construction crew.
Mitigation Measure 4.4.8: South Coast Air Quality Management District (SCAQMD) Rule 1113. Prior
to issuance of a Notice to Proceed, the Director of the City of Newport Beach Public Works Department or
designee shall verify that construction contracts and /or grading plans include a statement that the
Construction Contractor shall comply with the SCAQMD Rule 1113 on the use of architectural coatings.
Emissions associated with architectural coatings would be reduced by complying with these rules and
regulations, which include using pre - coated /natural colored building materials, using water -based or low -
volatile organic compounds (VOC) coating, and using coating transfer or spray equipment with high
transfer efficiency.
Finding: Mitigation measures are feasible and substantially lessen the significant construction air quality
impacts of the proposed project. The City Council hereby directs that these measures be adopted.
Implementation of these measures, which have been required or incorporated into the Project, and
included in the Mitigation Monitoring and Reporting Program, will substantially lessen the severity of a
significant effect but not to a less- than - significant level. Implementation of Mitigation Measures 4.4.1
through 4.4.8 would minimize construction emissions generated during project site preparation, grading,
and construction; however, even with implementation of the mitigation measures, NOx emissions would
exceed SCAQMD thresholds during the grading phase, ROC emissions would exceed SCAQMD
thresholds threshold during the grading phase and architectural coating, and PM10 concentrations would
exceed LST thresholds during grading. Construction air quality impacts would remain Significant and
Unavoidable.
2. Global Climate Change (Greenhouse Gases)
Impact: Global Climate Change. The proposed project would strive to reduce greenhouse gases (GHG)
emissions by meeting and exceeding Title 24 standards and by achieving Leadership in Energy and
Environmental Design for New Construction (LEED -NC) Silver Certification. The project would implement
mitigation measures to further reduce energy consumption and vehicular emissions. The City will monitor
the development of implementation requirements of AB 32, as issued by State agencies, and any
subsequently adopted GHG emissions reduction procedures and technologies relevant to the proposed
project.
The proposed project is consistent with and /or furthers the intent of numerous GHG reduction strategies
and is consistent with the City's General Plan goals and Climate Action Protection Program strategies,
which are designed to reduce energy consumption and GHG emissions. Compliance with the reduction
strategies implemented by the City will help to achieve the statewide reduction of GHG to 1990 levels;

however, this cannot ensure that the project would not exceed Threshold 4.8.1 because project
operations would result in more than 6,000 metric tons of carbon dioxide equivalent (COze) per year.
Therefore, the proposed project would result in a significant unavoidable project impact and result in a
cumulatively considerable contribution to an unavoidable cumulative impact related to activities that may
impede achievement of the State's goal for reducing GHG emissions to 1990 levels by 2020.
While the length and intensity of the construction period for this project would result in emissions that
contribute to the project's significant impact, even with implementation of mitigation measures, the short-
term construction - related emissions from this project would not in themselves be considered to present a
cumulatively considerable contribution to the impact of global climate change or may impede
achievement of the State's goal for reducing GHG emissions to 1990 levels by 2020.

source reduction, waste reduction and reuse, purchase of recycled content products, and source
separation and recycling of materials, including composting of biodegradable materials.
3. The City is committed to achieving Leadership in Energy and Environmental Design -New
Construction (LEED -NC) Silver certification for the new City Hall facility and Emergency
Operations Center (EOC) (see Project Design Feature [PDF] GHG -1, above).
4. The City will conduct regular energy audits, and commissioning during new construction and
renovation, as appropriate, with implementation of follow -up improvements to reduce energy
consumption for the new City Hall facility and the Emergency Operation Center (EOC).
5. The City will require contractors to use zero- or low- emission vehicles and equipment when
possible.
6. The City will landscape the proposed project site with a combination of native, drought - tolerant,
and ornamental plants (refer to PDF BIO 2).
7. The City will implement a comprehensive potable water conservation strategy for irrigation and
water service within the City Hall facility and the Emergency Operations Center (EOC).

of the City of Newport Beach Planning Department or designee shall ensure that notes are included on
construction and grading plans and referenced in the contractor's agreement that requires use of dust
suppression measures in the South Coast Air Quality Management District (SCAQMD) California
Environmental Quality Act (CEQA) Air Quality Handbook during project grading and construction. The
construction contractor shall be responsible for the implementation of the following dust suppression
measures:
1. Revegetate disturbed areas as soon as possible.
2. Increase active site watering to three times daily.
3. All excavating and grading operations shall be suspended when wind speeds (as instantaneous
gusts) exceed 25 miles per hour (mph).
4. When visible soil materials are carried to adjacent streets, those streets shall be swept once per

to Proceed, the Director of the City of Newport Beach Public Works Department or designee shall verify
that construction contracts and/or grading plans include a statement that work crews will shut off
equipment when not in use. During smog season (May through October), the overall length of the
construction period will be extended to minimize the occurrence of vehicles and equipment operating at
the same time and thereby decreasing the size of the area prepared each day.
Mitigation Measure 4.4.6: Traffic Obstruction Minimization. Prior to issuance of a Notice to Proceed,
the Director of the City of Newport Beach Public Works Department shall verify that construction contracts
and /or grading plans include a statement that construction trucks, to the extent feasible, shall avoid using
the streets during peak -hour traffic; if necessary, a flagperson shall be retained to maintain safety
adjacent to existing roadways.

encourage ridesharing and transit incentives for the construction crew.
Finding: Mitigation measures are feasible and substantially lessen the significant impacts of the project
related to GHG emissions and global climate change. The City Council hereby directs that these
measures be adopted. Implementation of these measures, which have been required or incorporated into
the Project, and included in the Mitigation Monitoring and Reporting Program, will substantially lessen the
severity of a significant effect but not to a less- than - significant level. Although the City has incorporated
alternative transportation components, including bicycle storage and changing rooms for employees and
Civic Center visitors and enhanced energy efficiency features, approximately 89-90 percent of the
project's total CO2e emissions are related to vehicle exhaust emissions. These vehicle exhaust emissions
themselves are controlled by the State and federal governments and are outside the control of the City;
thus, the City's efforts to improve on conventional construction techniques will not affect mobile source
emissions. The proposed project would result in a significant unavoidable project impact and result in a
cumulatively considerable contribution to an unavoidable cumulative impact related to activities that may
impede achievement of the State's goal for reducing GHG emissions to 1990 levels by 2020. These
impacts would remain Significant and Unavoidable.
Ill. ALTERNATIVES TO THE PROPOSED PROJECT
CEQA requires that an EIR describe a reasonable range of alternatives to the proposed project or to its
location that could feasibly attain most of the basic project objectives, but would avoid or substantially
lessen any of the significant effects, and that it evaluate the comparative merits of each of the
alternatives. Section 15126.6(b) of the State CEQA Guidelines states that the ". . . discussion of
alternatives shall focus on alternatives to the project or its location which are capable of avoiding or
substantially lessening any significant effects of the project, even if these alternatives would impede to
some degree the attainment of the project objectives, or would be more costly." The following section
discusses the project alternatives that were considered and analyzed in the EIR and summarizes the
consistency of these alternatives with the objectives of the proposed project.
The FEIR identified five alternatives as follows:
1. No Project/Development Pursuant to Existing General Plan (Alternative 1)
2. Development Pursuant to Existing Zoning (All park on proposed project site and a new City Hall on
the existing City Hall site) (Alternative 2)
3. Alternative Location at Vacant Land /Corporate Plaza West Site (Alternative 3)
4. Reduced Project (Alternative 4)
5. Modified Construction Schedule (Alternative 5)
City Hall and Park Development Plan
CEQA Findings of Fact
Page 40
The City's findings and facts in support of findings with respect to each of the alternatives considered are
provided below.
No Project Alternative
Description: This alternative, which is required by CEQA, assumes that the proposed project site and the
existing City Hall site would remain in the same condition as they were at the time the NOP was
published (April 2009). The setting of the site at the time the NOP was published is described throughout
Chapter 4.0 of the DEIR with respect to individual environmental issues and forms the baseline of the
impact assessment of the proposed project. This alternative represents the environmental conditions that
would exist if no new development of any kind were to occur on the project site. In addition, the No
Project/No Development Alternative anticipates that the existing City Hall would continue to operate
without new improvements to existing facilities.
Environmental Effects: The No Project/No Development Alternative assumes that the existing
conditions on both the proposed project site and the existing City Hall site would remain unchanged. The
proposed project site is currently vacant with the exception of the existing Library on the southern parcel.
The existing City Hall site is occupied by over 47,809 gross square feet of space in five buildings and five
temporary buildings (trailers). No new air pollutant emissions, construction emissions, or GHG emissions
would be generated by short-term construction emissions since no new construction is proposed. In
addition, no additional vehicle trips would be generated by the site with the No Project/No Development
Alternative therefore this alternative would not result in a significant impact related to global climate
change or GHG emissions.
Ability to Achieve Project Objectives: The No Project/No Development Alternative would partially
achieve two (2) of the 13 project objectives. The No ProjecUNo Development Alternative would preserve
(but not enhance) the on -site wetlands because no changes would occur on site. In addition, the No
ProjecUNo Development Alternative would protect (but not enhance) views from MacArthur Boulevard by
maintaining the existing view plane in the vicinity of the proposed project site. The No Project/No
Development Alternative would not achieve or further any other project objectives.
Findings: The City Council finds, pursuant to Public Resources Code Section 21081(a)(3), that specific
legal, economic, social, technical, or other considerations make the No Project Alternative identified in the
DEIR and FEIR infeasible.
Facts in Support of the Finding: This alternative would not be consistent with the requirements of
Measure B. A Space Utilization Assessment completed in 2002 found that the existing City Hall was
smaller than the city halls of comparable jurisdictions by between 11 and 25 percent and that space
conditions are functionally and qualitatively below desirable levels.' After completion of the Space
Utilization Study, the City added additional temporary buildings (portable buildings or trailers), but overall
the facilities are still considered to be over capacity. On -site parking is also considered to be insufficient to
meet demand. The City currently has no plans to expand staffing levels; however, the existing conditions
related to insufficient space and parking for current staff and service levels would remain under this
alternative.
The existing Library would also remain in its current condition. Due to the high demand for children's
materials and the high numbers of patrons, the existing Children's Room at the Central Library does not
adequately serve the existing community. The number of children in the City nearly doubled from 1990 to
2007. This figure includes the population of Newport Coast, which was annexed by the City in 2002. At
the same time, the percentage of children's materials checked out by Library patrons rose. In 2008,
children's materials accounted for 33 percent of all checkouts in the Newport Beach Public Library

(NBPL) system and 30 percent of all checkouts at the Central Library. No changes to the existing Library
or the Children's Room would occur under this alternative.
In addition to the library and City Hall complex, the alternative would forego various city benefits such as
a Civic Green, various transportation improvements that are part of the project design, as well as the
Emergency Operations Center. It should be noted, as well, that the passive park uses probably could not
be made ADA- compliant without substantial on site grading due to the existing grades. Thus, this
alternative potentially be inconsistent with General Plan Policies R.3.1 (Adequate Access) and R.3.3
(Facility Design), which encourage and require the City to provide park and recreational for persons with
disabilities and to design facilities, including trails, with consideration for views and access for persons in
wheelchairs.
Existing Zoning Alternative
Description: The Existing Zoning Alternative would include improvement of the northern and central
parcels for passive park uses and retention of the existing Library on the southern parcel. No changes/
expansion would occur to the existing Library under this Alternative. In conformance with the land uses
assigned to the project site under PC -27, the Existing Zoning Alternative includes construction and
operation of an approximately 16 ac passive park on the proposed project site. A pedestrian bridge could
be constructed to link the central and northern parcels, but it is unlikely that any public infrastructure
improvements (e.g., Treatment and Structural BMPs or roadway improvements) would occur. The on -site
wetlands could be preserved and enhanced under this alternative. Some water conservation measures
may be incorporated into the park, but overall sustainability options would be limited. For the purposes of
this analysis it is also assumed that City Hall would continue to operate at the existing City Hall site.
Environmental Effects: Because the Existing Zoning Alternative assumes development of a public park
on the entire project site, presumably with less grading, the air emissions from the Existing Zoning
Alternative would be substantially less than that of the proposed project. The Existing Zoning Alternative
would reduce or avoid significant unavoidable air quality impacts of the proposed project. In addition,
fewer additional vehicle trips would be generated by the site with the Existing Zoning Alternative therefore
this alternative would not result in a significant impact related to global climate change or greenhouse gas
emissions.
Ability to Achieve Project Objectives: The Existing Zoning Alternative would be potentially consistent
with four (4, 5, 8, and 9) of the 13 project objectives. The Existing Zoning Alternative would implement
General Plan policies by developing a passive park on the proposed project site, integrating the northern
and central parcels, preserving and enhancing on -site wetlands, and protecting and enhancing public
views from MacArthur Boulevard.
Finding: The City Council finds, pursuant to Public Resources Code Section 21081(a)(3), that specific
legal, economic, social, technical, or other considerations make the Existing Zoning Alternative identified
in the DEIR and FEIR infeasible.
Facts in Support of the Finding. This alternative would not be consistent with the requirements of
Measure B. A Space Utilization Assessment completed in 2002 found that the existing City Hall was
smaller than the City Halls of comparable jurisdictions by between 11 and 25 percent and that space
conditions are functionally and qualitatively below desirable levels.' After completion of the Space
Utilization Study, the City added additional temporary buildings (portable buildings or trailers) to the
existing City Hall site, but overall the existing facilities are still considered to be over capacity. Existing on-
site parking is also considered to be insufficient to meet demand. The City currently has no plans to
expand staffing levels; however, the existing conditions related to insufficient space and parking for
current staff and service levels would remain under this alternative.

The existing Library would also remain in its current condition. Due to the high demand for children's
materials and the high numbers of patrons, the existing Children's Room at the Central Library does not
adequately serve the existing community. The number of children in the City nearly doubled from 1990 to
2007. This figure includes the population of Newport Coast, which was annexed by the City in 2002. At
the same time, the percentage of children's materials checked out by Library patrons rose. In 2008,
children's materials accounted for 33 percent of all checkouts in the Newport Beach Public Library
(NBPL) system and 30 percent of all checkouts at the Central Library. No changes to the existing Library
or the Children's Room would occur under this alternative.
In addition to the library and City Hall complex, the alternative would forego various city benefits such as
a Civic Green and various transportation improvements that are part of the project design. It should be
noted, as well, that the passive park uses probably could not be made ADA- compliant without substantial
on site grading due to the existing grades. Thus, this alternative potentially be inconsistent with General
Plan Policies R.3.1 (Adequate Access) and R.3.3 (Facility Design), which encourage and require the City
to provide park and recreational for persons with disabilities and to design facilities, including trails, with
consideration for views and access for persons in wheelchairs.
Corporate Plaza West Alternative
Description: The Corporate Plaza West site is approximately 10 ac and consists of three existing
buildings located at 1200, 1400, and 1600 Newport Center. Figure 5.1 provides the location of this site.
The three buildings on site are approximately 40,000 sf each, for a total of 120,000 sf on site. Figure 5.2
provides an illustration of the site. The existing buildings are surrounded by surface parking. Although the
existing on -site buildings would provide sufficient office space to meet the needs of City Hall, the
relocation of City Hall to this site would require that the existing buildings on site be retrofitted, and design
modifications would be required to address unique City requirements for large public meeting /assembly
areas (e.g., City Council Chambers). For the purposes of this analysis it was assumed that an EOC
component would not be included in this alternative because of the additional retrofitting /construction
requirements of this use. This alternative assumes that the City would (a) purchase the property from the
Irvine Company or (b) lease office space from the Irvine Company. The current land owner may or may
not be willing to sell. Such a sale could be implemented by the City through eminent domain, but such a
course of action is contrary to the project objectives.
For the purposes of this analysis it is assumed that if the City Hall were not located on the proposed
project site, a 16 ac park would be developed on that site in conformance with the land uses assigned to
the project site under PC -27.
Environmental Effects: The Corporate Plaza West Alternative would result in less than significant air
quality impacts. The air quality emissions from the Corporate Plaza West Alternative would be less than
that of the proposed project. The Corporate Plaza West Alternative would reduce or avoid a significant
unavoidable air quality impact of the proposed project. In addition, the Corporate Plaza West Alternative
would result in less than significant project and cumulative impacts related to GHG emissions. The
Corporate Plaza West Alternative would reduce or avoid a significant unavoidable impact of the proposed
project.
Ability to Achieve Project Objectives: Locating the City Hall at the Corporate Plaza West site would be
potentially consistent with five (4, 5, 6, 8, and 9) of the 13 project objectives. With some modifications, the
Corporate Plaza West site would accommodate all existing City Hall uses. In addition, the construction of
a park on the proposed project site would implement General Plan policy by developing a passive park on
the proposed project site, preserve and enhance on -site wetlands, and protect and enhance public views
from MacArthur Boulevard. Construction of a pedestrian bridge at the proposed project site would
integrate the northern and southern parcels.

Finding: The City Council finds, pursuant to Public Resources Code Section 21081(a)(3), that specific
legal, economic, social, technical, or other considerations make the Corporate Plaza West Alternative
identified in the DEIR and FEIR infeasible.
Facts in Support of the Finding: Measure B was approved by the voters and specifically identifies the
proposed project site for the new City Hall and related improvements. Therefore, this alternative would
not be consistent with the requirements of Measure B, because it would preclude implementation of the
new City Hall at the proposed project site. In addition, it is the City's preference to own the Civic Center
buildings. The current land owner of this alternative site may or may not be willing to sell. Such a sale
could be implemented by the City through eminent domain, but such a course of action is contrary to the
project objectives.
The existing Library would also remain in its current condition. Due to the high demand for children's
materials and the high numbers of patrons, the existing Children's Room at the Central Library does not
adequately serve the existing community. The number of children in the City nearly doubled from 1990 to
2007. This figure includes the population of Newport Coast, which was annexed by the City in 2002. At
the same time, the percentage of children's materials checked out by Library patrons rose. In 2008,
children's materials accounted for 33 percent of all checkouts in the Newport Beach Public Library
(NBPL) system and 30 percent of all checkouts at the Central Library. No changes to the existing Library
or the Children's Room would occur under this alternative.
In addition, the alternative would forego various city benefits such as a Civic Green and various
transportation improvements that are part of the project design. It should be noted, as well, that the
passive park uses probably could not be made ADA- compliant without substantial on site grading due to
the existing grades. Thus, this alternative potentially be inconsistent with General Plan Policies R.3.1
(Adequate Access) and R.3.3 (Facility Design), which encourage and require the City to provide park and
recreational for persons with disabilities and to design facilities, including trails, with consideration for
views and access for persons in wheelchairs.
Reduced Project Alternative
Description: The Reduced Project Alternative evaluates the minimum number /type of improvements
needed to meet the requirements of Measure B. The proposed City Hall would consist of one, single -
story, 68,000 sf building with a 220 -space parking structure and 80 surface parking spaces. Because the
building would be a single story, the building would be below the view plane. As with the proposed
project, access would occur at Farallon Drive and Avocado Avenue, similar to the proposed project. In
addition to reducing the size of the proposed City Hall building, this alternative also eliminates the Library
expansion, eliminates the EOC, and reduces the size of the parking structure. For the purposes of this
analysis, all other project components (e.g., incorporation of conservation measures and project design
features) are considered to be the same as the proposed project. The Reduced Project Alternative would
reduce the quantity of excavated material removed from the project site from approximately 320,000
cubic yards (cy) (proposed project) to 150,000 cy.
Environmental Effects: The Reduced Project Alternative would result in a significant unavoidable
construction air quality impact. Operational air quality impacts would be less than significant. The
Reduced Project Alternative would result in reduced construction air quality impacts when compared to
the proposed project, but they would still be significant and unavoidable. In addition, the Reduced Project
Alternative would result in a significant contribution to a cumulative impact related to GHG emissions. The
Reduced Project Alternative would result in a less than significant project -level impact related to GHG
emissions. The Reduced Project Alternative would avoid a significant unavoidable project -level impact of
the proposed project, but would result in a comparable significant cumulative impact associated with GHG
emissions.

CEOA Findings of Fact
Page 44
Ability to Achieve Project Objectives: The Reduced Project Alternative would be potentially consistent
with 10 of the 13 project objectives (1, 3, 4, 5, 6, 7, 8, 9, 10, and 11). The Reduced Project Alternative
would not achieve three project objectives (2, 12, and 13).
Finding: The City Council finds, pursuant to Public Resources Code Section 21081(a)(3), that specific
legal, economic, social, technical, or other considerations make the Reduced Project Alternative identified
in the DEIR and FEIR infeasible.
Facts in Support of the Finding: The project alternative would not reduce the significant unavoidable
impacts of the proposed project to below a level of significance. In addition, although the Reduced Project
Alternative would result in the construction of a new City Hall on the proposed project site, it would not
incorporate City Hall into a larger Civic Center that would consist of an expanded Library, EOC, and a
Civic Green. The Reduced Project Alternative would not include the expanded Library or any functional or
thematic linkages between the existing Library and the proposed City Hall. Other than shared parking, the
two structures would operate independently of one another and would not be unified through design or
additional service features. The independent function of the two structures is not consistent with the
objective of creating a "Civic Center" type setting.
As noted above, the existing Library would also remain in its current condition. Due to the high demand
for children's materials and the high numbers of patrons, the existing Children's Room at the Central
Library does not adequately serve the existing community. The number of children in the City nearly
doubled from 1990 to 2007. This figure includes the population of Newport Coast, which was annexed by
the City in 2002. At the same time, the percentage of children's materials checked out by Library patrons
rose. In 2008, children's materials accounted for 33 percent of all checkouts in the Newport Beach Public
Library (NBPL) system and 30 percent of all checkouts at the Central Library. No changes to the existing
Library or the Children's Room would occur under this alternative.
In addition to the library and City Hall complex, the alternative would forego various city benefits such as
a Civic Green and various transportation improvements that are part of the project design. It should be
noted, as well, that the passive park uses probably could not be made ADA- compliant without substantial
on site grading due to the existing grades. Thus, this alternative potentially be inconsistent with General
Plan Policies R.3.1 (Adequate Access) and R.3.3 (Facility Design), which encourage and require the City
to provide park and recreational for persons with disabilities and to design facilities, including trails, with
consideration for views and access for persons in wheelchairs.
Modified Construction Schedule
Description: The Modified Construction Schedule Alternative considers construction of the project as
proposed in the FEIR, with a longer construction period and a reduced haul route. The project proposes a
32 -month construction schedule. The Modified Construction Schedule Alternative analyzes a 48 -month
construction schedule (thereby increasing the grading period by 16 months). The proposed project also
assumed that grading material (i.e., dirt from the project site) would be hauled 32 mi to the Prima
Deshecha landfill for disposal. The Modified Construction Schedule Alternative analyzes a construction
haul route of 16 mi, which is roughly the distance between the proposed project site and the planned
Orange County Great Park' project site. For the purposes of the analysis in the FEIR, all other project
components (e.g., incorporation of conservation measures and project design features) were considered
to be the same as the proposed project.
Environmental Effects: The Modified Construction Schedule Alternative would result in significant and
unavoidable construction air quality impacts. Operational air quality impacts would be less than
significant. The Modified Construction Schedule Alternative would result in a less severe impact related to
' The Orange County Great Park is a planned 1,300 -acre park located in the City of Irvine on the
former Marine Corps Air Station El Toro.

NOx than the proposed project. Emissions of ROC and the level of exceedance of the LST for PM10
concentrations would be comparable for this alternative and the proposed project. In addition, the
Modified Construction Schedule Alternative would result in a significant unavoidable impact related to
GHG emissions. The Modified Construction Schedule Alternative would result in impacts related to the
GHG emissions that would be comparable to those of the proposed project.
Ability to Achieve Project Objectives: The Modified Construction Schedule Alternative would be
potentially consistent with all 13 of the project objectives.
Finding: The City Council finds, pursuant to Public Resources Code Section 21081(a)(3), that specific
legal, economic, social, technical, or other considerations make the Modified Construction Schedule
Alternative identified in the DEIR and FEIR infeasible.
Facts in Support of the Finding: The project alternative would not reduce the significant unavoidable
impacts of the proposed project to below a level of significance. It would reduce the significant impact of
the proposed project related to daily NOx emissions during mass grading. However, even with the
substantial reduction in daily emissions of NOx achieved by extending the construction schedule, the
construction emissions still exceed the SCAQMD daily thresholds. The Modified Construction Schedule
Alternative also reduced the haul route distance to bring about a reduction in NOx emissions (NOx is a
pre- cursor of smog, which is produced a few days after the NOx is emitted). Although this alternative
reduces daily NOx emissions, this daily reduction is counterbalanced to a considerable degree by the fact
that the emission period would be substantially extended under this alternative since project NOx
emissions will occur for a period of 16 additional months. Daily NOx emissions would be decreased, but
not below a level of significance, and the extended construction period would extend the period of smog
production for that period of time. In addition, NOx emissions would affect the general region of the haul
route, thereby producing an extended period of smog in the localized haul route region for an additional
16 months.
Moreover, the impacts of PM10 concentrations, which are a localized impact directly related to grading,
could be substantial if they were extended as contemplated under this alternative. With the duration of
grading being extended under the Modified Construction Alternative schedule to 16 months, the effects
on neighboring residents and businesses would have to be endured for this extended period of months to
gain a relatively minor amount of reduction of PM10 (or dust) on a daily basis. Even though the
concentrations of PM10 from grading will be slightly reduced, the off- setting impacts of 16 months of
additional grading would be substantial. In addition, the Modified Construction Schedule Alternative would
require the same application of architectural coatings as the proposed project, and therefore it too would
result in an exceedance of the SCAQMD thresholds for reactive organic compounds (ROC). The
construction emissions of PM10 for Modified Construction Schedule Alternative would result in
concentrations that exceed the LST threshold. Therefore, significant impacts would still result for NO, and
ROC emissions and for PM10 concentrations with this alternative. Finally, the Modified Construction
Schedule Alternative would considerably lengthen the construction period and, therefore, the time frame
that residents would be exposed to disrupting construction traffic, noise, emissions, and other impacts.
In sum, the net reduction in the amount of NOx and PM10 created by the Modified Construction Alternative
does not benefit the environment or the community as much as a shortened period of construction that
would be created by the proposed project. As with the air quality issues above, the Modified Construction
Alternative would lessen the time period of grading and construction on a daily basis, but lengthen the
overall duration of general grading and construction activity at the site affecting traffic from the extended
truck hauling and noise impacts on adjacent properties and the library users for an additional 16 months.
On balance, because the benefits of the Modified Construction Alternative do not substantially reduce the
proposed projects air quality emissions (the daily NOx reductions are offset by the increased duration of
emissions), the relative impacts of extending the construction period by 16 months on the surrounding
community in regard to creation of smog, the affects of dust, the creation of noise and the inconvenience
of haul route truck traffic are not acceptable.

IV. GENERAL FINDINGS
1. The plans for the project have been prepared and analyzed so as to provide for public involvement in
the planning and CEQA processes.
2. To the degree that any impacts described in the FEIR are perceived to have a less than significant
effect on the environment or that such impacts appear ambiguous as to their effect on the
environment as discussed in the DEIR, the City has responded to key environmental issues and has
incorporated mitigation measures to reduce or minimize potential environmental effects of the
proposed project to the maximum extent feasible.
3. Comments regarding the DEIR received during the public review period have been adequately
responded to in written Responses to Comments attached to the FEIR. Any significant effects
described in such comments were avoided or substantially lessened by the standard conditions and
mitigation measures described in the FEIR.
4. The analysis contained in the DEIR and FEIR of the environmental effects and mitigation measures
represents the independent judgment and analysis of the City.

and are applicable to the proposed project site.
1. To the maximum extent practicable, no grading of coastal
sage scrub (CSS) habitat that is occupied by nesting
gnatcatchers shall occur during the breeding season
(February 15 —July 15). It is expressly understood that this
provision and the remaining provisions of these
"construction- related minimization measures" are subject
to public health and safety considerations. These
considerations include unexpected slope stabilization,
erosion control measures, and emergency facility repairs.
In the event of such public health and safety
circumstances, landowners or public agencies /utilities
shall provide the United States Fish and Wildlife
Service /California Department of Fish and Game
(USFWS /CDFG) with the maximum practicable notice (or
such notice as is specified in the NCCP /HCP) to allow for
capture of gnatcatchers, cactus wrens, and any other
CSS Identified Species that are not otherwise flushed
and shall carry out the following measures only to the
extent as practicable in the context of the public health
and safety considerations.
2. Prior to the commencement of grading operations or
other activities involving significant soil disturbance, all
areas of CSS habitat to be avoided under the provisions
of the NCCP /HCP shall be identified with temporary
fencing or other markers clearly visible to construction
personnel. Additionally, prior to the commencement of
grading operations or other activities involving
disturbance of CSS, a survey shall be conducted to
locate gnatcatchers and cactus wrens within 100 feet of
the outer extent of projected soil disturbance activities,
and the locations of any such species shall be clearly
marked and identified on the construction /grading plans.
3. A monitoring biologist, acceptable to USFWS /CDFG,

shall be on site during any clearing of CSS. The City of
Newport Beach Director of Planning or designee shall
advise USFWS /CDFG at least 7 calendar days (and
preferably 14 calendar days) prior to the clearing of any
habitat occupied by Identified Species to allow USFWS/
CDFG to work with the monitoring biologist in connection
with bird flushing /capture activities. The monitoring
biologist shall flush Identified Species (avian or other
mobile Identified Species) from occupied habitat areas
immediately prior to brush- clearing and earth - moving
activities. If birds cannot be flushed, they shall be
captured in mist nets, if feasible, and relocated to areas
of the site to be protected or to the NCCP /HCP Reserve
System. It shall be the responsibility of the monitoring
biologist to assure that Identified bird species will not be
directly impacted by brush - clearing and earth - moving
equipment in a manner that also allows for construction
activities on a timely basis.
4. Following the completion of initial grading /earth
movement activities, all areas of CSS habitat to be
avoided by construction equipment and personnel shall
be marked with temporary fencing or other appropriate
markers clearly visible to construction personnel. No
construction access, parking, or storage of equipment or
materials will be permitted within such marked areas.
5. CSS identified in the NCCP /HCP for protection and
located within the likely dust drift radius of construction
areas shall be periodically sprayed with water to reduce
accumulated dust on the leaves as recommended by the

these deposits. Where avoidance is not feasible, the
archaeological deposits shall be evaluated for their eligibility
for listing in the California Register of Historic Places. If the
deposits are not eligible, avoidance is not necessary. If the
deposits are eligible, adverse effects on the deposits must be
avoided, or such effects must be mitigated. Mitigation can
include, but is not necessarily limited to: excavation of the
deposit in accordance with a data recovery plan (see
California Code of Regulations Title 4(3) Section
5126.4(b)(3)(C)) and standard archaeological field methods
and procedures; laboratory and technical analyses of
recovered archaeological materials; production of a report
detailing the methods, findings, and significance of the
archaeological site and associated materials; curation of
archaeological materials at an appropriate facility for future
research and /or display; an interpretive display of recovered
archaeological materials at a local school, museum, or library;
and public lectures at local schools and /or historical societies
on the findings and significance of the site and recovered
archaeological materials.
It shall be the responsibility of the City Department of Public
Works to verify that the Monitoring Plan is implemented
during project grading and construction. Upon completion of
all monitoring /mitigation activities, the consulting
archaeologist shall submit a monitoring report to the City of
Newport Beach Director of Planning and to the South Central

The sensitive sediments that have been identified within the
project include the Middle Pleistocene marine and terrestrial
sediments as well as middle Miocene Monterey formation

sediments. A paleontologist will not be required on site if
excavation is only occurring in artificial fill.
The paleontologist shall prepare a Paleontological Resources
Impact Mitigation Program (PRIMP) for the proposed project.
The PRIMP should be consistent with the guidelines of
the Society of Vertebrate Paleontologists (SVP) (1995) and
should include but not be limited to the following:
Attendance at the pregrade conference in order to
explain the mitigation measures associated with the
project.
• During construction excavation, a qualified vertebrate
paleontological monitor shall initially be present on a full -
time basis whenever excavation will occur within the
sediments that have a High paleontological sensitivity
rating and on a spot -check basis in sediments that have a
Low sensitivity rating. Based on the significance of any
recovered specimens, the qualified paleontologist may
set up conditions that will allow for monitoring to be
scaled back to part-time as the project progresses.
However, if significant fossils begin to be recovered after
monitoring has been scaled back, conditions shall also be
specified that would allow increased monitoring as
necessary. The monitor shall be equipped to salvage
fossils and/or matrix samples as they are unearthed in
order to avoid construction delays. The monitor shall be
empowered to temporarily halt or divert equipment in the
area of the find in order to allow removal of abundant or
large specimens.
• The underlying sediments may contain abundant fossil
remains that can only be recovered by a screening and
picking matrix; therefore, these sediments shall be
occasionally be spot- screened through one- eighth to one -
twentieth -inch mesh screens to determine
City Hall and Park Development Plan
Mitigation Monitoring and Reporting Program
Page 19

whether microfossils exist. If microfossils are
encountered, additional sediment samples (up to 6,000
pounds) shall be collected and processed through one -
twentieth -inch mesh screens to recover additional fossils.
Processing of large bulk samples is best accomplished at
a designated location within the project that will
be accessible throughout the project duration but will also
be away from any proposed cut or fill areas. Processing
is usually completed concurrently with construction, with
the intent to have all processing completed before, or just
after, project completion. A small corner of a staging or
equipment parking area is an ideal location. If water is not
available, the location should be accessible for a water
truck to occasionally fill containers with water.
• Preparation of recovered specimens to a point of
identification and permanent preservation. This includes
the washing and picking of mass samples to recover
small invertebrate and vertebrate fossils and the removal
of surplus sediment from around larger specimens to
reduce the volume of storage for the repository and the
storage cost for the developer.
• Identification and curation of specimens into a museum
repository with permanent, retrievable storage, such as
the Natural History Museum of Los Angeles County
(LACM).
Preparation of a report of findings with an appended,
itemized inventory of specimens. When submitted to the
City of Newport Beach Director of Planning or designee,
the report and inventory would signify completion of the
program to mitigate impacts to paleontological resources.

specified designee
been prepared by Leighton Consulting, Inc. titled
Geotechnical Study for the Proposed City Hall and Park
Development Plan for the Environmental Impact Report
(EIR), Newport Beach, California (July 2009) (included in
Appendix K of this EIR). Design, grading, and construction
shall be performed in accordance with the requirements of
the City of Newport Beach Building Code and the California
Building Code (CBC) applicable at the time of grading,
appropriate local grading regulations, and the
recommendations of the project geotechnical consultant as
summarized in a final written report, subject to review by the
Director of the City of Newport Beach Building Department or
designee prior to commencement of grading activities.
Recommendations in the Geotechnical Study for the
Proposed City Hall and Park Development Plan for the
Environmental Impact Report (EIR), Newport Beach,
California are summarized below.
• Site Grading. The subgrade below the planned
foundations for buildings and improvements planned in
the area of the Library expansion shall be overexcavated
in order to provide uniform support for the buildings.
Additional remedial grading shall be required to develop
relatively uniform support characteristics and reduce the
potential for postconstruction swell and distortions to the
building in areas where claystone is exposed.
• Shoring. Shoring shall be required during excavation for
the retaining wall proposed along MacArthur Boulevard
due to the anticipated space constraint for slope lay back
and adverse bedrock structure. Design parameters of the
City Hall and Park Development Plan
Mitigation Monitoring and Reporting Program
Page 22
Project Design Features (PDFs) and Mitigation Measures
Responsible Party
Timing for PDF or
Mitigation Measure
temporary shoring and retaining wall shall be based on
the bedrock strike and dip and the final configuration of
the wall. In addition., the retaining wall shall be designed
to include possible geologic surcharge from the bedrock.
Shoring systems feasible for the site are expected to
include cantilever shoring such as soldier piles and
lagging in conjunction with tiebacks in areas when the
depth of excavation exceeds 10 to 15 feet (ft).
Dewatering. If groundwater or perched water is
encountered during project grading and construction,
dewatering may be necessary. Methods of dewatering
shall be submitted by the contractor and reviewed and
approved by the geotechnical consultant and City
Building Official prior to commencement of grading
activities.
• Subsurface Drainage. Groundwater is not expected to
be a project constraint. In the unlikely event groundwater
is encountered during construction and is at a depth that
would impact project structures (postconstruction), the
subterranean slabs shall be designed to resist hydrostatic
uplift, or a permanent subfloor drainage system shall be
included in the design of the slab. The design of
subterranean slabs shall be reviewed and approved by
the City Building Official prior to issuance of building
permits.
Temporary Excavations. All temporary excavations
shall be treated in accordance with the State of California
version of Occupational Safety and Health Administration
(OSHA) excavation regulations, Construction Safety
Orders for Excavation General Requirements. The sides
of excavations shall be shored or sloped in accordance
with OSHA regulations. OSHA allows the sides of
unbraced excavations, up to a maximum height of 20 ft,
to be cut to a %H:1 V (horizontal:vertical) slope for Type A
soils, 1 H:1 V for Type B soils, and 1.51-1:11V for Type C
City Hall and Park Development Plan
Mitigation Monitoring and Reporting Program

Project Design Features (PDFs) and Mitigation Measures
Responsible Party
Timing for PDF or

soils. The on -site soils (Terrace Deposits) within the
proposed excavation depths generally conform to OSHA
Soil Type B. The formational bedrock may be classified
as Soil Type A but will require careful evaluation by the
project Certified Engineering Geologist. The Type A
classification is not recommended where adverse (out -of-
slope) bedding orientations exist, and special site - specific
design parameters will be required in those areas. Heavy
construction loads, such as those resulting from
stockpiles and heavy machinery, shall be kept a minimum
distance equivalent to the excavation height or 5 ft,
whichever is greater, from the excavation unless the
excavation is shored and these surcharges are
considered in the design of the shoring system.
• Spread Footing Foundations. Upon completion of the
grading (cutting) required to establish the proposed
building pad elevations, the proposed structures may be
supported by a spread footing foundation system.
Bearing capacities shall be dependent on the final
foundation elevation and structural loadings of the
buildings and shall be reviewed by the geotechnical
consultant prior to implementation.
• Slab on Grade. At -grade floor slabs of the proposed
structures may be designed and constructed as a slab -
on -grade supported directly on properly compacted fill or
competent bedrock. If a bedrock artificial fill transition is
encountered, the planned subgrade elevation shall be
overexcavated at least 3 ft and replaced with properly
compacted fill. The structural engineer shall design the
slab and determine the required thickness and
reinforcement based on structural load requirements.
• Retaining Walls. The proposed development is expected
to require various types of earth - retaining structures: free-
standing cantilever retaining walls; temporary shoring;
and below grade walls for several of the proposed

structures. In general, free - standing retaining structures
planned at the site shall be backfilled with granular, very
low expansive soil and be constructed with a backdrain.
• Geotechnical Review and Future Testing. Additional
site testing and final design evaluation shall be conducted
by the project geotechnical consultant to refine and
enhance these recommendations. Grading plan review
shall also be conducted by the project geotechnical
consultant and the Director of the City of Newport Beach
Building Department or designee prior to the start of
grading to verify that the recommendations developed
during the geotechnical design evaluation have been
appropriately incorporated into the project plans. Final
design shall be based on testing and analyses of the
near - surface soils following the completion of grading.
Design, grading, and construction shall be conducted in
accordance with the specifications of the project
geotechnical consultant as summarized in a final report
based on the CBC applicable at the time of grading and
building and the City of Newport Beach Building Code.
On -site inspection during grading shall be conducted by
the project geotechnical consultant and the City Building
Official to ensure compliance with geotechnical
specifications as incorporated into project plans.
